ITEMS 1 AND 2:  BUSINESS AND PROPERTIES

GENERAL

    Ocean Energy, Inc. (OEI or the Company) is one of the largest independent
oil and gas exploration and production companies in the U.S. The Company was
created in March 1998 by the strategic merger (the Merger) of OEI and United
Meridian Corporation (UMC). As of December 31, 1998, the Company had estimated
proved reserves of approximately 134.3 MMBbls of oil (46% of total proved
reserves) and 945.8 Bcf of natural gas (54% of total proved reserves) for a
total of 291.9 MMBOE, with a Present Value of Future Net Revenues of
approximately $916.7 million and a Standardized Measure of Discounted Future Net
Cash Flows of approximately $903.8 million. The Company holds a diversified
portfolio of properties with both domestic and international exposure organized
into three primary operating units: (i) the continental shelf and deepwater
areas of the Gulf of Mexico (the Gulf of Mexico Region); (ii) the West African
countries of Cote d'Ivoire, Equatorial Guinea and Angola, the Asian Basin
countries of Pakistan and Bangladesh and the Middle East country of the Republic
of Yemen (the International Region); and (iii) certain onshore areas of North
America, including Western Canada and the Midcontinent and Rocky Mountain
regions of the U.S. (the North American Onshore Region).

RECENT DEVELOPMENTS

     On November 24, 1998, OEI and Seagull Energy Corporation (Seagull) entered
into a merger agreement that provides for a stock-for-stock merger (Seagull
Merger) of OEI with and into Seagull. In connection with the Seagull Merger,
which is anticipated to close by the end of the first quarter of 1999, OEI
stockholders will receive one share of common stock of Seagull for each existing
outstanding share of OEI. Seagull will amend its Articles of Incorporation to
change its name to Ocean Energy, Inc. (New Ocean). After the Seagull Merger, the
stockholders of OEI will own approximately 61.5% of the outstanding common stock
of New Ocean and the stockholders of Seagull will own the remaining 38.5% of the
outstanding common stock of New Ocean. The Seagull Merger is expected to qualify
as a tax-free transaction with no gain or loss recognized for U.S. federal
income tax purposes by the stockholders of OEI upon receipt of New Ocean common
stock in exchange for shares of OEI common stock and is subject to each
Company's stockholders' approval and certain other conditions.

     The combination of OEI and Seagull will create the seventh largest United
States independent oil and gas company based on production and the tenth largest
based on total proved reserves, in each case based on 1997 information. On a pro
forma basis, New Ocean will have estimated proved reserves of approximately
496 MMBOE at year end 1998 and combined 1998 estimated production of
approximately 68 MMBOE. The larger size and scale provided by the merger will
allow New Ocean to capitalize on a wider range of opportunities and to develop
and operate larger exploration and development projects than either OEI or
Seagull would be able to do on a stand-alone basis. This larger size will also
allow New Ocean to operate more competitively in the current low commodity price
environment and to make opportunistic acquisitions.

     OEI and Seagull are developing plans to integrate their operations
immediately after the merger to take full advantage of the benefits and
synergies the merger will create that would not have been available to either
company on a stand-alone basis. Those benefits include substantial cost savings,
a more geographically diversified reserve composition, a larger capital base,
greater financial strength and flexibility and an enhanced ability to make
further acquisitions.

OIL AND GAS PROPERTIES

     The Company's operating activities are focused primarily in three operating
units: (i) the continental shelf and deepwater areas (water depth of over 1,500
feet) of the Gulf of Mexico (Deepwater Gulf), (ii) the West African countries of
Cote d'Ivoire, Equatorial Guinea and Angola, the Asian Basin countries of
Pakistan and Bangladesh and the Middle East country of the Republic of Yemen,
and (iii) certain onshore areas of North America, including Western Canada and
the Midcontinent and Rocky Mountain regions of the U.S. The following table
summarizes the Company's proved reserves by operational area:

     held constant). The amounts are before income taxes and therefore are not
     the same as the "Standardized Measure" disclosed in Note 16 of the Notes to
     Consolidated Financial Statements.

GULF OF MEXICO REGION

    In the Gulf of Mexico Region, the Company held interests in approximately
1.0 million gross (0.6 million net to the Company) acres as of December 31,
1998, and currently holds 138 outer continental shelf and 48 deepwater blocks as
well as approximately 90 state leases. On the continental shelf, the Company's
operations are in three primary areas: (i) the Mississippi River Delta located
in state and federal waters near the mouth of the Mississippi River; (ii) the
Central Gulf of Mexico located in the shallow federal waters offshore Louisiana;
and (iii) the western portion of the Gulf of Mexico. In the deepwater Gulf of
Mexico, the Company's blocks are located offshore Louisiana in water depths
ranging from 2,500 to 7,500 feet, where the Company expects to commence drilling
operations in 1999. The following is a description of each of the Company's
major operating areas in the Gulf of Mexico Region:

     Continental Shelf. The Company's current production operations in the
continental shelf area are comprised of 32 Company operated fields, as well as
15 non-operated fields. These production operations encompass approximately
300,000 gross (180,000 net to the Company) acres, representing approximately
117.5 MMBOE, or 40% of the Company's total proved reserves. For 1998, the
Company's average daily production was 32.9 MBbls of oil and 166.9 MMcf of gas
or 60.7 MBOE. Some of the Company's premier properties in this area include the
South Pass 24 field and the South Pass 27 field located in the highly prolific
area of the East Bay Complex. The Company owns an average 99% working interest
in these fields.

     On March 3, 1998, the Company announced that it was expanding its
exploration program through an exclusive Gulf of Mexico Exploration Alliance
(the Alliance) with Shell Offshore, Inc. (SOI). Pursuant to the terms of the
Alliance, the Company and SOI will initially drill 25 exploration prospects, all
delineated by 3-D seismic, on over 141,000 gross acres across the continental
shelf in the Gulf of Mexico. Ten of the wells under the Alliance have been
drilled through December, 1998. Under the Alliance, the Company will participate
for 25% of SOI's working interest in the Alliance's 25 exploration prospects.

     Deepwater Gulf. The Company is a party to the Deepwater Gulf exploration
venture with Conoco encompassing 155,520 gross (57,658 net to the Company) acres
located off the coast of Louisiana in water depths ranging from 2,500 to 7,500
feet. The Company began drilling the first deepwater well in this venture in
February, 1999. The Company's working interest in this well is 25%. In addition
to the Conoco venture, the Company acquired leases for six blocks located in
Keathley Canyon, encompassing 34,560 gross and net acres, and the Company is a
party to two separate joint venture arrangements encompassing 57,600 gross
(28,800 net to the Company) acres in water depths ranging from 7,000 to 9,000
feet. The Company believes that the Deepwater Gulf provides substantial reserve
and production growth opportunities.

INTERNATIONAL REGION

    In the International Region, the Company currently holds interests in 12
West African blocks (two of which are currently under production). In addition,
the Company has interests in the Asian Basin countries of Pakistan and
Bangladesh where seismic and geophysical evaluations are ongoing. The Company's
acreage in the International Region is generally held pursuant to PSCs with host
governments. Under the Company's 19 PSCs (16 of which the Company operates), the
Company holds contract interests ranging from 15% to 100%. As of December 31,
1998, the

                                       2

Company had approximately 75.4 MMBOE of proved reserves attributable to the
International Region (approximately 26% of the Company's total proved reserves)
with average daily production during 1998 of 24.4 MBOE per day. The following is
a description of each of the Company's major operating areas in the
International Region:

     Cote d'Ivoire. In Cote d'Ivoire, the Company has five PSCs through which it
holds contract interests ranging from 35% to 80% in five blocks totaling
approximately 1.8 million gross (1.0 million net to the Company) acres. As of
December 31, 1998, the Company operated all five PSCs in Cote d'Ivoire. As a
result of the successful discoveries and subsequent production history, the
Company recognized net proved reserves of 6.4 MMBbls of oil and 167.7 Bcf of
natural gas at December 31, 1998. In addition, the Company's net production from
the blocks totaled 1,080 MBbls and 7,824 MMcf for the year ended December 31,
1998. During 1998 in Cote d'Ivoire, the Company participated in four exploratory
wells, two of which were successful. No development wells have been drilled in
1998.

     In 1997, the Company constructed a liquid propane gas (LPG) plant to
extract liquids (propane, butane and natural gasoline) from the current natural
gas production in the country. The plant is capable of handling 75 to 95 MMcf
per day of natural gas flow producing up to 45,000 metric tons of LPG per year
and commenced operations in the fourth quarter of 1998. Total costs incurred on
such plant through December 31, 1998 were approximately $21.4 million.

     Equatorial Guinea. In Equatorial Guinea, the Company has four PSCs through
which the Company holds contract interests ranging from 24% to 94% totaling
approximately 1.7 million gross (1.2 million net to the Company) acres. In
addition, the Company's net production from Block B averaged 17.9 MBOE per day
in 1998. As of December 31, 1998, the Company operated three of the four PSCs in
Equatorial Guinea.

     At December 31, 1998, the Company recognized net proved reserves of 41.0
MMBbls of oil in Equatorial Guinea. In 1998, the Company participated in eight
exploratory wells, three of which were successful, and three development wells,
each of which was successful.

     Work on a new development project on one of the blocks in Equatorial Guinea
began in 1998 to provide additional production capacity to develop the existing
field discoveries in such block. Extensive 3-D seismic shoots are currently
under review to further evaluate opportunities on these blocks.

     Angola. In February and May 1998, the government of the Republic of Angola
awarded the Company participations in two exploration blocks with 20% and 15%
contract interests, respectively. In addition, in May 1998, the government of
the Republic of Angola consented to the Company's participation in an additional
exploration block with a 30% interest. In the aggregate, the three blocks cover
2.7 million gross (0.5 million net to the Company) acres, two of which are
located in the high potential deepwater basins offshore Angola where several
major discoveries have been announced. The Company will operate one of the
blocks.

     Pakistan. The Company has signed five PSCs with the government of Pakistan,
covering 7.7 million gross (6.7 million net to the Company) acres. The Company
holds contract interests of 85% in each of four blocks and 95% in the remaining
block. The Company operates all five of these PSCs. Geological and geophysical
studies have begun and will be conducted during the next two years of the
exploration license on the five blocks, with possible drilling by the end of
1999.

    Bangladesh. In February 1997, the Company signed a PSC covering a block in
the Chittagong Hills tracts onshore Bangladesh, which PSC the Company currently
operates. The Company has geological and geophysical work currently underway
toward possible drilling in 1999. The block covers 3.3 million gross (3.0
million net to the Company) acres. The Company currently holds a 90% contract
interest in this PSC.

     Republic of Yemen. In August 1998, the Company acquired a 60% contract
interest in South Howarime Block 43. The contract covers 0.7 million gross (0.4
million net to the Company) acres and the Company is the operator. The Company
anticipates acquiring seismic data and drilling two exploratory wells over the
next several years.

NORTH AMERICAN ONSHORE REGION

    In its North American Onshore Region, the Company had interests in 3.0
million gross (1.2 million net to the Company) acres in 15 states and Western
Canada as of December 31, 1998. Domestically, the Company conducts

activities in two primary areas: (i) certain Midcontinent areas, including the
Anadarko Basin and onshore Texas; and (ii) certain Rocky Mountain areas,
including operations in Montana and Wyoming. The Company's Canadian assets are
generally located in Western Alberta, Canada. As of December 31, 1998, the
Company had approximately 99.0 MMBOE of proved reserves attributable to the
North American Onshore Region (approximately 34% of the Company's total proved
reserves) with average daily production during 1998 of 30.7 MBOE per day. The
following is a description of each of the Company's major producing areas in the
North America Onshore Region:

     Rocky Mountains. The Rocky Mountain area comprises approximately 550,000
net acres and represents approximately 40.7 MMBOE, or 14% of the Company's
proved reserves. The Company's largest property in the Rocky Mountain area is
the Bearpaw field in the north central portion of Montana where shallow,
low-cost development drilling has made the Company the largest producer of
natural gas in the state. The Company holds interests in nearly 500 wells,
currently producing in excess of 62.3 MMcf of natural gas gross (36.6 MMcf net
to the Company) per day. Other properties of importance in the area include
projects that are underway in the Powder River Basin and the East Triangle Field
in Wyoming.

     Midcontinent. The Company's Midcontinent area comprises approximately
262,000 net acres and represents approximately 36.0 MMBOE, or 12% of the
Company's total proved reserves. Projects in this area include continued
low-risk development drilling in the Anadarko Basin and West Texas and several
waterflood oil projects. Some of the Company's most significant properties in
the Midcontinent area are in the Young Mendota Field in Texas, and the Buffalo
and Longhorn areas of West Texas.

     Canada. The Western Canada area comprises approximately 359,000 net acres
and represents approximately 22.4 MMBOE, or nearly 8% of the Company's total
proved reserves. On February 8, 1999, Company announced its intention to divest
its interests in all Canadian oil and gas properties and related assets during
1999.

     There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
development expenditures, including many factors beyond the control of the
Company. Reserve engineering is a subjective process of estimating underground
accumulations of oil and natural gas that cannot be measured in an exact manner,
and the accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment.
The quantities of oil and natural gas that are ultimately recovered, production
and operating costs, the amount and timing of future development expenditures
and future oil and natural gas sales prices may all differ from those assumed in
these estimates. Therefore, the Present Value of Future Net Revenues figures
shown above should not be construed as the current market value of the estimated
oil and natural gas reserves attributable to the Company's properties. The
information set forth in the

                                       4

<PAGE>   7

foregoing tables includes revisions of certain volumetric reserve estimates
attributable to proved properties included in the preceding year's estimates.
Such revisions are the result of additional information from subsequent
completions and production history from the properties involved or the result of
a decrease (or increase) in the projected economic life of such properties
resulting from changes in product prices.

     In accordance with the Commission's guidelines, the engineers' estimates of
future net revenues from the Company's properties and the Present Value of
Future Net Revenues thereof are made using oil and natural gas sales prices in
effect as of the dates of such estimates and are held constant throughout the
life of the properties except where such guidelines permit alternate treatment,
including the use of fixed and determinable contractual price escalations.
Prices for natural gas and, to a lesser extent, oil are subject to substantial
seasonal fluctuations and prices for each are subject to substantial
fluctuations as a result of numerous other factors. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Oil and Gas
Marketing and Major Customers."

</TABLE>

     Productive wells consist of producing wells and wells capable of
production, including gas wells awaiting pipeline connections. Wells that are
completed in more than one producing horizon are counted as one well. Of the
gross wells reported above, 113 had multiple completions.

    Acreage Data. Undeveloped acreage includes leased acres on which wells have
not been drilled or completed to a point that would permit the production of
commercial quantities of oil and gas, regardless of whether or not such acreage
contains proved reserves. A gross acre is an acre in which an interest is owned.
A net acre is deemed to exist when the sum of fractional ownership interests in
gross acres equals one. The number of net acres is the sum of the fractional
interests owned in gross acres expressed as whole numbers and fractions thereof.
The following table sets forth the approximate developed and undeveloped acreage
in which the Company held a leasehold mineral or other interest at December 31,
1998.

DRILLING ACTIVITIES

     Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered. There can be no
assurance that new wells drilled by the Company will be productive or that the
Company will recover all or any portion of its investment. Drilling for oil and
natural gas may involve unprofitable efforts, not only from dry wells, but from
wells that are productive but do not produce sufficient net revenues to return a
profit after drilling, operating, and other costs. The cost of drilling,
completing and operating wells is often uncertain. The Company's drilling
operations may be curtailed, delayed or canceled as a result of numerous
factors, many of which are beyond the Company's control, including title
problems, weather conditions, compliance with governmental requirements and
shortages or delays in the delivery of equipment and services. Many of the
Company's prospects are located in deepwater areas, and exploration and
development of these prospects requires use of deepwater drilling rigs.
Availability of such deepwater rigs may be limited in certain parts of the
world.

</TABLE>

OIL AND GAS MARKETING AND MAJOR CUSTOMERS

     The revenues generated by the Company's operations are highly dependent
upon the prices of, and demand for, oil and natural gas. The price received by
the Company for its oil and natural gas production depends on numerous factors
beyond the Company's control, including seasonality, the condition of the U.S.
economy, particularly the manufacturing sector, foreign imports, political
conditions in other oil-producing and natural gas-producing countries, the
actions of the Organization of Petroleum Exporting Countries and domestic
government regulation, legislation and policies. Declines in the prices of oil
and natural gas have had an adverse effect on the carrying value of the
Company's proved reserves and the Company's revenues, profitability and cash
flow. Although the Company is not currently experiencing any significant
involuntary curtailment of its oil or natural gas production, market, economic
and regulatory factors may in the future materially affect the Company's ability
to sell its oil or natural gas production. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

     The Company markets its oil and gas production to numerous purchasers under
a combination of short and long-term contracts. During 1998, Mobil Sales and
Supply Corporation accounted for 15% of the Company's oil and gas revenues as
the purchaser of the Company's production in Equatorial Guinea. In addition,
sales to SOI accounted for 12% of the Company's oil and gas revenues for the
year ended December 31, 1998. The Company had no other purchasers that accounted
for greater than 10% of its oil and gas revenues for the year ended December 31,
1998. See Note 9 to the Company's Consolidated Financial Statements.

     Due to the availability of other markets and pipeline connections, the
Company does not believe that the loss of any single oil or natural gas customer
would adversely affect the Company's results of operations.

COMPETITION

     The oil and gas industry is highly competitive in all of its phases. The
Company encounters competition from other oil and gas companies in all areas of
its operations, including the acquisition of producing properties. The Company's
competitors include major integrated oil and natural gas companies and numerous
independent oil and natural gas companies, individuals and drilling and income
programs. Many of its competitors are large, well established companies with
substantially larger operating staffs and greater capital resources than the
Company's and which, in many instances, have been engaged in the energy business
for a much longer time than the Company. Such companies may be able to pay more
for productive oil and natural gas properties and exploratory prospects and to
define, evaluate, bid for and purchase a greater number of properties and
prospects than the Company's financial or human resources permit. The Company's
ability to acquire additional properties and to discover reserves in the future
will be dependent upon its ability to evaluate and select suitable properties
and to consummate transactions in a highly competitive environment.

     Capital available for investment in the oil and natural gas industry may
decline significantly as a result of decreases in product prices, future changes
in federal income tax laws and adverse economic conditions generally affecting
the industry and the country as a whole.

OPERATING HAZARDS AND UNINSURED RISKS

     The Company's operations are subject to hazards and risks inherent in
drilling for and production and

                                       6

<PAGE>   9


transportation of oil and natural gas, such as uncontrollable flows of oil, gas
or well fluids, fires, natural disasters, explosions, encountering formations
with abnormal pressures, blowouts, cratering, pipeline ruptures, spills,
pollution, releases of toxic gas and other environmental hazards and risks, any
of which can result in loss of hydrocarbons, environmental pollution, personal
injury claims, and other damage to properties of the Company and others. In
addition, the Company may be liable for environmental damages caused by previous
owners of property purchased by the Company or its predecessors. As a result,
substantial liabilities to third parties or governmental entities may be
incurred, the payment of which could reduce or eliminate the funds available for
exploration, development or acquisitions, or result in loss of the Company's
properties. Additionally, certain of the Company's oil and gas operations are
located in an area that is subject to tropical weather disturbances, some of
which can be severe enough to cause substantial damage to facilities and
possibly interrupt production. As protection against operating hazards and in
accordance with customary industry practices, the Company maintains insurance
coverage against some, but not all, potential losses. The Company's coverages
include, but are not limited to, operator's extra expense, physical damage on
certain assets, employer's liability, comprehensive general liability,
automobile, workers' compensation and loss of production income insurance. The
Company believes that its insurance is adequate and customary for companies of a
similar size engaged in operations similar to those of the Company, but losses
could occur for uninsurable or uninsured risks or in amounts in excess of
existing insurance coverage. The occurrence of an event that is not fully
covered by insurance could have an adverse impact on the Company's financial
condition and results of operations.

EMPLOYEES

     As of December 31, 1998, the Company had approximately 800 full-time
employees, none of whom is represented by any labor union. Included in the total
were approximately 500 corporate employees located in the Company's Houston,
Texas; Lafayette, Louisiana; Denver, Colorado; Calgary, Alberta; Abidjan, Cote
d'Ivoire; and Malabo, Equatorial Guinea offices and in various field locations
whose functions are associated with management, engineering, geology,
geophysics, operations, land, legal, accounting, financial planning and
administration. Of this amount, approximately 300 full-time employees are
responsible for the supervision and operation of its field activities. The
Company considers its relations with its employees to be good.

OTHER FACILITIES

    The Company leases its Houston, Texas headquarters under a lease covering
approximately 112,000 square feet, expiring in December 2006. In addition, the
Company leases approximately 33,000 square feet of office space in Denver,
Colorado, approximately 8,600 square feet of office space in Baton Rouge,
Louisiana, approximately 71,000 square feet of office space in Lafayette,
Louisiana and approximately 1,150 square feet of office space in New Orleans,
Louisiana, where some of the Company's technical personnel are collectively
located. The Company also leases additional space in its Calgary, Alberta office
and for its division and field operating offices in the U.S and certain foreign
locations.

     The Company also leases dock and warehouse space in Venice, Louisiana;
Morgan City, Louisiana; and Abidjan, Cote d'Ivoire.

TITLE TO PROPERTIES

     The Company believes it has satisfactory title to all of its producing
properties in accordance with standards generally accepted in the oil and gas
industry. The Company's properties are subject to customary royalty interests,
liens incident to operating agreements, liens for current taxes and other
burdens which the Company believes do not materially interfere with the use of
or affect the value of such properties. The Minerals Management Service (MMS)
and Louisiana State Mineral Board must approve all transfers of record title or
operating rights on its respective leases. The MMS and Louisiana State Mineral
Board approval process can in some cases delay the requested transfer for a
significant period of time.

GOVERNMENTAL REGULATION

     The Company's oil and gas exploration, production and related operations
are subject to extensive rules and regulations promulgated by Federal and state
agencies. Failure to comply with such rules and regulations can result in
substantial penalties. The regulatory burden on the oil and gas industry
increases the Company's cost of doing

                                       7

<PAGE>   10


business and affects its profitability. Because such rules and regulations are
frequently amended or reinterpreted, the Company is unable to predict the future
cost or impact of complying with such laws.

     The State of Louisiana and many other states require permits for drilling
operations, drilling bonds, and reports concerning operations and impose other
requirements relating to the exploration and production of oil and gas. Such
states also have statutes or regulations addressing conservation matters,
including provisions for the unitization or pooling of oil and gas properties,
the establishment of maximum rates of production from wells, and the regulation
of spacing, plugging, and abandonment of such wells.

     Historically, the transportation and sale for resale of natural gas in
interstate commerce have been regulated pursuant to the Natural Gas Act of 1938,
the Natural Gas Policy Act of 1978 (the NGPA), and the regulations promulgated
thereunder by the Federal Energy Regulatory Commission (the FERC). In the past,
the federal government has regulated the wellhead price of natural gas.
Deregulation of wellhead sales in the natural gas industry began with the
enactment of the NGPA. In 1989, the Natural Gas Wellhead Decontrol Act was
enacted, which amended the NGPA to remove wellhead price controls on all
domestic natural gas as of January 1, 1993. While sales by producers of natural
gas, and all sales of oil, condensate and natural gas liquids, can currently be
made at uncontrolled market prices, Congress could re-enact price controls in
the future.

     Several major regulatory changes have been implemented by the FERC from
1985 to the present that have had a major impact on natural gas pipeline
operations, services and rates and thus have significantly altered the marketing
and price of natural gas. Commencing in April 1992, the FERC issued Order Nos.
636, 636-A and 636-B (collectively, "Order No. 636"), which, among other things,
require each interstate pipeline company to "restructure" to provide
transportation separate or "unbundled" from the sale of gas and to make
available on an open and nondiscriminatory basis numerous constituent services
(such as gathering services, storage services, firm and interruptible
transportation services) and to adopt a new ratemaking methodology to determine
appropriate rates for those services. To the extent the pipeline company or its
sales affiliate makes gas sales as a merchant in the future, it does so in
direct competition with all other sellers pursuant to private contracts;
however, pipeline companies and their affiliates were not required to remain
"merchants" of gas and several of the interstate pipeline companies have become
"transporters" only. Following the conclusion of individual restructuring
proceedings for each interstate pipeline pursuant to Order No. 636, the FERC has
approved, with modifications, all of the restructuring plans implementing Order
No. 636 on every interstate pipeline.

     On July 16, 1996, the Court of Appeals for the District of Columbia Circuit
(D.C. Circuit) issued its opinion on review of Order No. 636. The opinion upheld
most elements of Order No. 636 including the unbundling of sales and
transportation services, curtailment of pipeline capacity, implementation of the
capacity release program and the mandatory imposition of straight-fixed-variable
(SFV) rate design for interstate pipeline companies. The D.C. Circuit did remand
certain aspects of Order No. 636 to the FERC for further explanation including,
inter alia, the FERC's decision to exempt pipelines from sharing in gas supply
realignment (GSR) costs caused by restructuring; FERC's selection of a
twenty-year term matching cap for the right-of-first-refusal mechanism; the
FERC's restriction on the entitlement of no-notice transportation service to
only those customers receiving bundled sales service at the time of
restructuring; and FERC's determination that pipelines should focus on
individual customers, rather than customer classes, in mitigating the effects of
SFV rate design. On May 12, 1997, the United States Supreme Court denied
certiorari of the D.C. Circuit's decision.

     On February 27, 1997, the FERC issued its order on remand (Order No.
636-C). The order reaffirmed the holding of Order No. 636 that pipelines should
be entitled to recover 100 percent of their prudently incurred GSR costs.
Moreover, the FERC determined that since Order No. 636, the average length of
transportation contracts was substantially less than 20 years. Thus, FERC
reduced the contract matching cap for the right-of-first-refusal mechanism to
five years. In light of the varied post-restructuring experience with no-notice
service, the FERC also decided to no longer limit a pipeline's no-notice service
to its bundled sales customers at the time of restructuring. Finally, the FERC
reaffirmed that pipelines should focus on individual customers, rather that
customer classes, in mitigating the effects of SFV rate design. On May 28, 1998,
FERC denied requests for rehearing of Order No. 636-C. Appeals of individual
pipeline restructuring orders are still pending before the D.C. Circuit.

     On May 31, 1995, the FERC issued a policy statement on how interstate
natural gas pipelines can recover the costs of new pipeline facilities. The
policy statement focused on whether projects would be priced on a rolled-in
basis (rolling in the expansion costs with the existing facilities) or on an
incremental basis (establishing separate cost-of

                                       8

<PAGE>   11


services and separate rates for the existing and expansion facilities). The
policy statement established a presumption in favor of rolled-in rates when the
rate increase to existing customers from rolling in the new facilities is 5% or
less. In the policy statement, the FERC contemplated that the resolution of
pricing methodology would take place in individual proceedings based on the
facts and circumstances of the project. The Company cannot predict what action
the FERC will take in the individual proceedings.

     In October of 1992 Congress passed the Energy Policy of 1992 (Energy Policy
Act). The Energy Policy Act deemed petroleum pipeline rates in effect for the
365-day period ending on the date of enactment of the Energy Policy Act or that
were in effect on the 365th day preceding enactment and had not been subject to
complaint, protest or investigation during the 365-day period to be just and
reasonable under the Interstate Commerce Act. The Energy Policy Act also
provides that complaints against such rates may only be filed under the
following limited circumstances: (i) a substantial change has occurred since
enactment in either the economic circumstances or the nature of the services
which were a basis for the rate; (ii) the complainant was contractually barred
from challenging the rate prior to enactment; or (iii) the rate is unduly
discriminatory or preferential. The Energy Policy Act further required FERC to
issue rules establishing a simplified and generally applicable ratemaking
methodology for petroleum pipelines, and to streamline procedures in petroleum
pipeline proceedings. On October 22, 1993, the FERC responded to the Energy
Policy Act directive by issuing Order No. 561, which adopts a new indexing rate
methodology for petroleum pipelines. Under the new regulations, which were
effective January 1, 1995, petroleum pipelines are able to change their rates
within prescribed ceiling levels that are tied to the Producer Price Index for
Finished Goods, minus one percent. Rate increases made pursuant to the index
will be subject to protest, but such protests must show that the portion of the
rate increase resulting from application of the index is substantially in excess
of the pipeline's increase in costs. The new indexing methodology can be applied
to any existing rate, even if the rate is under investigation. If such rate is
subsequently adjusted, the ceiling level established under the index must be
likewise adjusted.

     In Order No. 561, FERC said that as a general rule pipeliners must utilize
the indexing methodology to change their rates. FERC indicated, however, that it
was retaining cost-of-service ratemaking, market-based rates, and settlements as
alternatives to the indexing approach. A cost-of-service methodology will also
continue to be used to determine just and reasonable initial rates for new
services. A pipeline can also follow a cost-of-service approach when seeking to
increase its rates above index levels for uncontrollable circumstances. A
pipeline can seek to charge market-based rates if it can establish that it lacks
market power. Finally, a pipeline can establish rates pursuant to settlement if
agreed upon by all current shippers.

     On May 10, 1996, the D.C. Circuit affirmed Order No. 561. The Court held
that by establishing a general indexing methodology along with limited
exceptions to indexed rates, FERC had reasonably balanced its dual
responsibilities of ensuring just and reasonable rates and streamlining
ratemaking through generally applicable procedures. Because of the novelty and
uncertainty surrounding the indexing methodology, as well as the possibility of
the use of cost-of-service ratemaking and market-based rates, the Company is not
able at this time to predict the effects of Order No. 561, if any, on the
transportation costs associated with oil production from the Company's oil
producing operations.

     Under the Outer Continental Shelf Lands Act (OCSLA), the FERC also
regulates certain activities on the outer continental shelf (OCS). Under OCSLA,
all gathering and transporting of oil and natural gas on the OCS must be
performed on an "open and non-discriminatory" basis. Consequently, the Company's
gathering and transportation facilities located on the OCS must be made
available to third parties. In addition, the MMS imposes regulations relating to
development and production of oil and gas properties in federal waters. Under
certain circumstances, the MMS may require any Company operations on federal
leases to be suspended or terminated. Any such suspensions or terminations could
materially and adversely affect the Company's financial condition and
operations.

     Certain of the Company's businesses are subject to regulation by the
Federal Natural Gas Pipeline Safety Act of 1968 and other state and Federal
environmental statutes and regulations.

     The Oil Pollution Act (OPA) imposes a variety of regulations on
"responsible parties" related to the prevention of oil spills and liability for
damages resulting from such spills in U.S. waters. A "responsible party"
includes the owner or operator of an onshore facility, vessel or pipeline, or
the lessee or permittee of an 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

                                       9

<PAGE>   12


spill was caused by gross negligence or willful misconduct or resulted from
violation of a federal safety, construction or operating regulation. If the
party fails to report a spill or to cooperate fully in its cleanup, liability
limits likewise do not apply. Few defenses exist to the liability imposed by the
OPA.

     The OPA also imposes ongoing requirements on a responsible party, 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 million 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 barrels (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 by most facilities range from $10 million in specified
state waters to $35 million in federal OCS waters, with higher amounts, up to
$150 million in certain limited circumstances where the MMS believes such a
level is justified by the risks posed by the quantity or quality of oil that is
handled by the facility. On March 25, 1997, the MMS promulgated a proposed rule
implementing these OPA financial responsibility requirements. Under the proposed
rule, the amount of financial responsibility required for a facility would
depend on the "worst case" oil spill discharge volume calculated for the
facility. For oil and gas producers such as the Company operating offshore
facilities in OCS waters, worst case discharge volumes of up to 35,000 barrels
will require a financial responsibility demonstration of $35.0 million, while
worst case discharge volumes in excess of 35,000 barrels will require
demonstrations ranging from $70.0 million to $150.0 million.

     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 or proposed
rule will result in the imposition of substantial additional annual costs to the
Company in the future or otherwise materially adversely effect 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 Region. OPA also imposes other requirements on facility operators,
such as the preparation of an oil spill contingency plan. The Company has such
plans in place. The failure to comply with ongoing requirements or inadequate
cooperation in a spill event may subject a responsible party to civil or even
criminal liability.

U.S. ENVIRONMENTAL MATTERS

     The Company's operations and properties are subject to extensive and
changing federal, state and local laws and regulations relating to environmental
protection, including the generation, storage, handling, emission,
transportation and discharge of materials into the environment, and relating to
safety and health. The recent trend in environmental legislation and regulation
is generally toward stricter standards, and this trend will likely continue.
These laws and regulations may require the acquisition of a permit or other
authorization before construction or drilling commences and for certain other
activities; limit or prohibit construction, drilling and other activities on
certain lands lying within wilderness or wetlands and other protected areas; and
impose substantial liabilities for pollution resulting from the Company's
operations. The permits required for various of the Company's operations are
subject to revocation, modification and renewal by issuing authorities. The
Company believes that its operations currently are in substantial compliance
with applicable environmental regulations.

     Governmental authorities have the power to enforce compliance with their
regulations, and violations are subject to fines, injunction, or both. The
Company does not expect environmental compliance matters to have a material
adverse effect on its financial position. It is also not anticipated that the
Company will be required in the near future to expend amounts that are material
to the financial condition or operations of the Company by reason of
environmental laws and regulations, but because such laws and regulations are
frequently changed, and may impose increasingly stricter requirements, the
Company is unable to predict the ultimate cost of complying with such laws and
regulations.

The following are examples of environmental, safety and health laws that relate
to the Company's operations:

    Solid Waste. The Company's operations may generate and result in the
transportation, treatment, and disposal of both hazardous and nonhazardous solid
wastes that are subject to the requirements of the federal Resource Conservation
and Recovery Act (RCRA) and comparable state and local requirements. The
Environmental Protection

                                       10

<PAGE>   13


Agency (EPA) is currently considering the adoption of stricter disposal
standards for nonhazardous waste. Further, it is possible that some wastes that
are currently classified as nonhazardous, perhaps including wastes generated
during pipeline, drilling and production operations, may in the future be
designated as "hazardous wastes," which are subject to more rigorous and costly
treatment, storage, transportation and disposal requirements. Such changes in
the regulations may result in additional expenditures or operating expenses by
the Company. On August 8, 1998, the EPA added four petroleum refining wastes to
the list of RCRA hazardous wastes. While the full impact of the rule has yet to
be determined, the rule may, as of February 1999, impose increased expenditures
and operating expenses on the Company, which may take on increased obligations
relating to the treatment, storage, transportation and disposal of certain
petroleum refining wastes that previously were not regulated as hazardous
wastes.

    Hazardous Substances. The Comprehensive Environmental Response, Compensation
and Liability Act (CERCLA) and comparable state statutes, also known as
"Superfund" laws, impose liability, without regard to fault or the legality of
the original conduct, on certain classes of persons for the release or
threatened release of a "hazardous substance" into the environment. These
persons include the current and past owner or operator of a site, and companies
that transport, dispose of or arrange for the disposal of the hazardous
substances found at the site. CERCLA also authorizes the EPA or state agency,
and in some cases, third parties to take actions in response to releases or
threats of releases of hazardous substances and to seek to recover from the
classes of responsible persons the costs they incur. Although "petroleum" is
excluded from CERCLA's definition of a "hazardous substance," in the course of
its ordinary operations the Company may generate other materials which may fall
within the definition of a "hazardous substance", and certain petroleum refining
wastes that previously were not regulated as hazardous waste may now fall within
the definition of CERCLA hazardous substance. The Company may be responsible
under CERCLA for all or part of the costs required to clean up sites at which
such wastes have been disposed and for natural resource damages. The Company has
not received any notification that it may be potentially responsible for cleanup
costs under CERCLA or any comparable state law.

     Air. The Company's operations are subject to the Clean Air Act (CAA) and
comparable state and local requirements. Amendments to the CAA were adopted in
1990 and contain provisions that may result in the gradual imposition of certain
pollution control requirements with respect to air emissions from the operations
of the Company, particularly where a company constructs a new facility or
modifies an existing facility. The EPA has been developing regulations to
implement these requirements. The Company may be required to incur certain
capital expenditures in the next several years for air pollution control
equipment in connection with maintaining or obtaining operating permits and
approvals addressing other air emission-related issues. However, the Company
does not believe its operations will be materially adversely affected by any
such requirements.

     Water. The Federal Water Pollution Control Act (FWPCA) or Clean Water Act
(CWA) imposes restrictions and strict controls regarding the discharge of
produced waters and other oil and gas wastes into navigable waters. Such
discharges are typically authorized by National Pollutant Discharge Elimination
System (NPDES) permits. The FWPCA provides for civil, criminal and
administrative penalties for any unauthorized discharges and along with the Oil
Pollution Act of 1990, imposes substantial potential liability for the costs of
removal, remediation and damages. State laws for the control of water pollution
also provide varying civil, criminal and administrative penalties and
liabilities in the case of a discharge of petroleum, its derivatives or
hazardous substances into state waters. In addition, the Coastal Zone Management
Act authorizes state implementation and development of programs of management
measures for non-point source pollution to restore and protect coastal waters.
As of January 1, 1997, the Company's federal NPDES permits prohibit the
discharge of produced water, and other substances generated by the oil and gas
industry, from wells located in the coastal waters of Louisiana. The Louisiana
Department of Environmental Quality (LDEQ), as administrator of the NPDES
permits in Louisiana, issued on December 30, 1996, and reissued on February 28,
1997, an emergency rule to allow continued discharge of produced waters in the
coastal area, subject to a zero discharge requirement by no later than December
31, 1999 for produced water being currently discharged into major deltaic passes
of the Mississippi River. On February 24, 1997, LDEQ issued to the Company a
compliance order allowing it to temporarily discharge produced water into
Southwest Pass, a major deltaic pass of the Mississippi River. The Company has
submitted to LDEQ a compliance plan for achievement of zero discharge of
produced water at its East Bay Central Facilities by no later than July 1, 1999,
and has commenced operations to drill injection wells and install miscellaneous
equipment. The Company is also in the process of reformatting a portion of its
East Bay facilities to allow for discharge of produced water in the offshore
areas, to the extent allowed by its NPDES permits. Although the costs to
reformat Company operations to comply with these zero discharge mandates under
federal or state law may be significant, the Company believes that these costs
will not have a material adverse impact on the Company's financial conditions
and operations.

                                       11

<PAGE>   14


     Protected Species. The Endangered Species Act (ESA) seeks to ensure that
activities do not jeopardize endangered or threatened animal, fish and plant
species, nor destroy or modify the critical habitat of such species. Under the
ESA, exploration and production operations, as well as actions by federal
agencies, may not significantly impair or jeopardize the species or its habitat.
The ESA provides for criminal penalties for willful violations of the ESA. Other
statutes which provide protection to animal and plant species and which may
apply to the Company's operations include, but are not necessarily limited to,
the Marine Mammal Protection Act, the Marine Protection, Research and
Sanctuaries Act, the Fish and Wildlife Coordination Act, the Fishery
Conservation and Management Act, the Migratory Bird Treaty Act and the National
Historic Preservation Act.

     Wetlands. Pursuant to the FWPCA, the United States Corps of Engineers, with
oversight by the EPA, administers a complex program that regulates activities in
wetland areas. Some of the Company's operations are in areas that have been
designated as wetlands and, as such, are subject to permitting requirements.
Failure to properly obtain a permit or violation of permit terms could result in
the issuance of compliance orders, restorative injunctions and a host of civil,
criminal and administrative penalties. The Company believes that it is currently
in substantial compliance with these permitting requirements.

     Wildlife Refuges/Bird Sanctuaries. Portions of the Company's properties are
located in or adjacent to federal and state wildlife refuges and bird
sanctuaries. The Company's operations in such areas must comply with regulations
governing air and water discharge which are more stringent than in its other
areas of operations. The Company has not been, and does not anticipate that it
will be, materially affected by any such requirements.

     Safety and Health. The Company's operations are subject to the requirements
of the federal Occupational Safety and Health Act (OSHA) and comparable state
statutes. The OSHA hazard communication standard, the EPA
community-right-to-know regulations under Title III of the Federal Superfund
Amendment and Reauthorization Act, and similar state statutes require that
certain information be organized and maintained about hazardous materials used
or produced in operations. Certain of this information must be provided to
employees, state and local government authorities and citizens.

CANADIAN ENVIRONMENTAL MATTERS

     The oil and natural gas industry is subject to environmental regulation
pursuant to local, provincial and federal legislation in Canada. Environmental
legislation provides for restrictions and prohibitions on releases or emissions
of various substances produced in association with certain oil and gas industry
operations. In addition, legislation requires that well and facility sites be
abandoned and reclaimed to the satisfaction of provincial authorities. A breach
of such legislation may result in the imposition of fines and penalties.
Environmental legislation in Alberta was substantially revised in 1993 to update
and consolidate the various acts applicable to environmental protection. The
various acts were consolidated into the Environmental Protection and Enhancement
Act, proclaimed April 22, 1993 and became effective September 1, 1993. Under the
new Act, environmental standards and compliance for releases, clean-up and
reporting are stricter. Also, the range of enforcement actions available and
severity of penalties are significantly increased. The changes had an
incremental but not material effect on the cost of conducting operations in
Alberta. The full extent of the impact will not be known until the Government of
Alberta releases its enforcement policy. Federal environmental regulations are
generally restricted to the use and transport of certain restricted and
prohibited substances and the environmental assessment of projects which require
an approval from a federal authority. The Company anticipates making necessary
expenditures of both a capital and expense nature as a result of the
increasingly stringent laws relating to the protection of the environment. The
Company believes that it is in material compliance with applicable environmental
laws and regulations in Canada.

ABANDONMENT COSTS

     The Company is typically responsible for payment of abandonment costs on
the oil and gas properties it operates. As of December 31, 1998, total future
abandonment costs on the Company's oil and gas properties estimated to be
incurred were approximately $156.5 million. Estimates of abandonment costs and
their timing may change due to many factors including actual production results,
inflation rates, and changes in environmental laws and regulations.

     In connection with its acquisition of certain properties in the Mississippi
River Delta, the Company entered into two escrow agreements to provide for the
future plugging and abandonment costs of these properties. One agreement

                                       12

<PAGE>   15


requires the Company to make monthly deposits until the escrow account equals
$40.0 million. The other agreement requires monthly deposits until the escrow
account equals $7.5 million. Such funds are restricted as to withdrawal by the
agreement. With respect to any specifically planned plugging and abandonment
operation, funds are partially released to the Company when it presents to the
escrow agent the planned plugging and abandonment operations approved by the
applicable governmental agency, with the balance to be released upon the
presentation by the Company to the trustee of evidence from the governmental
agency that the operation was conducted in compliance with applicable laws and
regulations. As of December 31, 1998, the escrow balances totaled $10.8 million.
The Company is currently in negotiations to release these escrow balances.

     In addition, the MMS requires lessees of OCS properties to post bonds to
cover the costs of the plugging and abandonment of wells located offshore and
the removal of all production facilities. Operators in the OCS waters of the
Gulf of Mexico are currently required to post area wide bonds of $3.0 million or
$500,000 per producing lease and supplemental bonds at the discretion of the
MMS. The Company has posted with the MMS an area wide bond of $3.0 million and
during 1998 became exempt from any requirement to post supplemental bonds. The
Company does not anticipate that the cost of any such bonding requirements will
materially affect the Company's financial position. Under certain circumstances,
the MMS may require any Company operations on federal leases to be suspended or
terminated. Any such suspensions or terminations could have a material adverse
effect on the Company's financial condition and operations.

ITEM 3.  LEGAL PROCEEDINGS

     The two lawsuits brought on behalf of stockholders of UMC, Newman v.
Carson, et al. (Civil Action No. 16109-NC) in the Court of Chancery of the State
of Delaware and Ross v. Brock, et al. (Cause No. 98-00845) in the 164th Judicial
District Court of Harris County, Texas were settled and dismissed during the
fourth quarter 1998. As part of the settlements, the Company made additional
disclosures concerning the merger with UMC and paid certain legal fees. The
effects of the settlements are not considered material to the Company.

     The EPA has indicated that the Company may be potentially responsible for
costs and liabilities associated with alleged releases of hazardous substances
at two sites in Louisiana under CERCLA. Given the extremely large number of
companies that have been identified as potentially responsible for releases of
hazardous substances at the sites and the small volume of hazardous substances
allegedly disposed of by the companies whose properties the Company acquired,
management believes that the Company's potential liability arising from these
sites, if any, will not have a material adverse impact on the Company.

     In February 1998, the Tulane Environmental Law Clinic (Clinic), claiming to
represent several southeastern Louisiana environmental groups, gave notice that
it intended to file a CWA citizens' suit against the Company after a sixty-day
waiting period expired in connection with the discharge of produced water in
East Bay. As of June 1, 1998, this sixty-day waiting period has expired and no
such suit has been filed by the Clinic. The Clinic claimed that the Company was
violating the CWA by discharging produced water from its East Bay Central
Facilities into Southwest Pass, and stated that it would seek an injunction to
require the Company to cease its discharge of produced water, and would seek
civil penalties and attorney's fees. If the Clinic were to successfully obtain
an injunction, certain production operations at the Company's East Bay
Facilities could be interrupted until favorable resolution of the issue in court
or accelerated completion of the Company's plan to reformat operations to
provide for alternative produced water disposal. The Company believes that its
zero discharge compliance plan, which permits the temporary continued discharge
of produced water into Southwest Pass through July 1, 1999, is completely lawful
as authorized by a Compliance Order issued by the LDEQ, and intends to
vigorously defend any such citizens' suit, if filed The Clinic has delivered
similar notices to other Louisiana coastal producers.

     The Company is a named defendant in lawsuits and is a party in governmental
proceedings from time to time arising in the ordinary course of business. While
the outcome of such lawsuits or other proceedings against the Company cannot be
predicted with certainty, management does not expect these matters to have a
material adverse effect on the financial position or results of operations of
the Company.

(1) Nonrecurring merger costs of $39.0 million have been recorded in the first
    quarter of 1998. These costs consist primarily of investment banking and
    other transaction fees, employee severances and relocation costs as well as
    the write-off of deferred financing costs related to the former credit
    facilities replaced by the Existing Credit Facility in March 1998. Before
    consideration of the $39.0 million of nonrecurring merger costs and the
    $539.9 million write-down of oil and gas properties, net income (loss) would
    have been $(39.2) million for the year ended December 31, 1998.

(2) Earnings before interest, taxes, depreciation, depletion and amortization.
    EBITDA has not been reduced for the nonrecurring merger costs incurred in
    the quarter ended March 31, 1998, the write-downs of oil and gas properties
    in 1998 or the extraordinary loss for the year ended December 31, 1997.
    EBITDA is not intended to represent cash flow in accordance with generally
    accepted accounting principles and does not represent the measure of cash
    available for distribution. EBITDA is not a generally accepted accounting
    principle measure, but provides additional information for evaluating the
    Company's ability to make payments in respect of the Notes. EBITDA is not
    intended as an alternative to earnings from continuing operations or net
    income.

(3) Excludes results of hedging activities which increased (decreased) revenue
    recognized in the year ended December 31, 1998, 1997, 1996, 1995 and 1994 by
    $24.5 million, $(1.3) million, $(22.6) million, $3.6 million and $1.4
    million, respectively. Including the effect of hedging activities, the
    Company's average oil price per Bbl received was $13.21, $18.54, $20.24,
    $17.05 and $14.67 in the years ended December 31, 1998, 1997, 1996, 1995 and
    1994, respectively, and the average gas price per Mcf received was $1.89,
    $2.28, $2.18, $1.60 and $1.72 in the years ended December 1998, 1997, 1996,
    1995 and 1994, respectively.

 (4) Excludes production and ad valorem taxes.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     Effective March 27, 1998, pursuant to that certain Agreement and Plan of
Merger dated December 22, 1997 (as amended, the "UMC Merger Agreement"), UMC was
merged with and into the Company. As a result of the Merger, the separate
existence of UMC ceased and the Company succeeded to all of the rights and
obligations of UMC. Pursuant to the UMC Merger Agreement, at the effective time
of the Merger, the Company's stockholders received 2.34 shares of the combined
Company's common stock for each share of the Company's common stock then owned,
and UMC stockholders received 1.30 shares of the combined Company's common stock
for each share of UMC stock then owned. The Merger, completed on March 27, 1998,
was treated as a pooling of interests for accounting purposes.

     This financial review summarizes the combined financial condition and
results of operations giving retroactive effect to the Merger and should be read
in conjunction with the Company's consolidated financial statements and the
notes thereto included elsewhere in this Form 10-K.

GENERAL

     The Company's operating activities are organized into three primary
operating units: (i) the continental shelf and deepwater areas of the Gulf of
Mexico, (ii) the West African countries of Cote d'Ivoire, Equatorial Guinea and
Angola, the Asian Basin countries of Pakistan and Bangladesh, and the Middle
East country of the Republic of Yemen and (iii) certain onshore areas of North
America, including Western Canada and the Midcontinent and Rocky Mountain
regions of the U.S. As of December 31, 1998, the Company had estimated proved
reserves of approximately 134.3 MMBbls of oil and 945.8 Bcf of natural gas, or
an aggregate of approximately 291.9 MMBOE, with a Present Value of Future Net
Revenues before income taxes of approximately $916.7 million and a Standardized
Measure of Discounted Future Net Cash Flows of approximately $903.8 million. On
a BOE basis, approximately 46% of the Company's proved reserves at December 31,
1998 were oil.

ANTICIPATED EFFECT OF SEAGULL MERGER

     New Ocean intends to account for the Seagull Merger as a purchase under
generally accepted accounting principles. Because OEI stockholders will own a
majority of the New Ocean common stock, the accounting treatment of the Seagull
Merger will reflect OEI acquiring Seagull in a "reverse purchase". Under this
method of accounting, New Ocean's historical results for periods prior to the
Seagull Merger will be the same as OEI's historical results. On the date of the
Seagull Merger, New Ocean will record the assets acquired and liabilities
assumed from OEI based upon their historical costs and the assets and
liabilities of Seagull will be recorded at their estimated fair market values.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1998 AND 1997

     Operating revenues. The Company's total operating revenues decreased $28.9
million, or 5%, to $523.3 million for the year ended December 31, 1998, from
$552.2 million for 1997. Production levels for 1998 increased 25% to 42,279 MBOE
from 33,699 for 1997 in spite of significant storm-related shut-ins of
production in the Gulf of Mexico during the third quarter of 1998. The decrease
in oil and gas revenues is due to the precipitous decline in world crude oil and
natural gas prices experienced in 1998 offset by increased oil volumes in the
Gulf of Mexico and Equatorial Guinea and overall higher gas volumes.

     Oil revenues decreased $34.9 million, or 10%, to $300.2 million for 1998
from $335.1 million for 1997, the result of increased worldwide production
volumes more than offset by a decline in the average realized price

received. Oil production increased 26% to 22,728 MBbls for 1998 as compared to
1997 due primarily to increased oil production in the Gulf of Mexico and
Equatorial Guinea. The average sales price before hedging for oil decreased 35%
to $12.13 for 1998 compared to $18.54 for 1997.

     Natural gas revenues increased $7.9 million, or 4%, to $222.0 million for
1998 from $214.1 million for 1997, the result of increased worldwide production
which more than offset the decline in prices received for gas. Natural gas
production for 1998 was 117,305 MMcf, an increase of 25% over 1997 volumes due
primarily to increased production in the Gulf of Mexico, Cote d'Ivoire and
Canada and the impact of acquisitions, offset by property sales, storm-related
shut-ins in the Gulf of Mexico and natural production declines in North America.
The average sales price before hedging for natural gas decreased 18% to $1.89
per Mcf for 1998 as compared to $2.30 for 1997.

     For the year ended December 31, 1998, the Company's total revenues were
further affected by a $25.8 million increase in hedging revenues. In order to
manage its exposure to price risks in the sale of its crude oil and natural gas,
the Company from time to time enters into price hedging arrangements. The
Company's average sales prices including hedging for oil and natural gas for
1998 were $13.21 per Bbl and $1.89 per Mcf compared to $18.54 per Bbl and $2.28
per Mcf for 1997.

     Production costs. Total production costs increased $38.5 million, or 31%,
to $162.9 million for 1998 from $124.4 million for 1997. This increase primarily
results from fluctuations in normal operating expenses, including operating
expenses associated with increased production from new facilities, timing of
workover and maintenance activities, and the impact of property acquisitions.
Production and operating costs (costs incurred to operate and maintain wells and
related equipment, excluding ad valorem and production taxes) increased $0.33
per BOE, or 11%, to $3.35 per BOE for 1998, from $3.02 per BOE for 1997. This
unit increase is primarily the result of the timing of certain workover and
maintenance activities.

     General and administrative expenses. General and administrative expenses
increased $11.2 million, or 37%, to $41.4 million for 1998 from $30.2 million
for 1997. This increase is primarily due to costs of increased corporate
staffing associated with both an increase in drilling activities and the
Company's property acquisitions in 1997. In addition, costs related to a new
systems implementation, partially offset by an increase in the capitalization of
a portion of the salaries paid to employees directly engaged in the acquisition,
exploration and development of oil and gas properties in accordance with the
full cost method of accounting, contributed to the increase. As a result of
these factors, general and administrative expenses per BOE increased by $0.08
per BOE, or 9%, to $0.98 per BOE for 1998, from $0.90 per BOE for 1997.

     Depreciation, depletion and amortization expense. Depreciation, depletion
and amortization (DD&A) expense increased $45.5 million, or 18%, to $293.9
million for 1998, from $248.4 million for 1997. This variance is primarily
attributable to the Company's increased production and related current and
future capital costs from the 1997 and 1998 Gulf of Mexico and international
drilling programs and acquisitions, partially offset by the effect of an
increase in proved reserves resulting from such programs and acquisitions. Oil
and gas DD&A decreased $.43 per BOE, or 6%, to $6.80 per BOE for 1998, from
$7.23 per BOE for 1997. The non-cash write-downs of oil and gas properties
recognized in 1998 contributed to the decrease.

     Write-down of oil and gas properties. As required under the full cost
method of accounting, capitalized costs are limited to the sum of the present
value of future net revenues using current unescalated pricing discounted at 10%
related to estimated production of proved reserves and the lower of cost or
estimated fair value of unevaluated properties, all net of expected income tax
effects. At June 30, 1998, the Company recognized a non-cash impairment of oil
and gas properties in the amount of $218.4 million pre-tax ($135.4 million
after-tax) pursuant to this ceiling limitation required by the full cost method
of accounting for oil and gas properties, using certain improvements in pricing
experienced after period end. The Company recognized an additional write-down at
December 31, 1998 in the amount of $321.5 million pre-tax ($199.3 million after
tax). The write-downs are primarily the result of the precipitous decline in
world crude oil and natural gas prices experienced during 1998.

     Interest and debt expense. Reported interest and debt expense increased
$13.7 million, or 28%, to $62.8 million for 1998, from $49.1 million for 1997.
This increase is primarily the result of an increase in debt levels during 1998
resulting from the capital spending program for 1998 and lower than expected
cash flows due to the deterioration in product prices, offset by an increase in
capitalized interest on significant projects in process. Average total debt
outstanding for 1998 was $1,022.1 million as compared to $556.6 million for
1997.

                                       18

     Merger Costs. Merger costs of $39.0 million relating to the Company's
merger with UMC were recorded in the first quarter of 1998. These costs consist
primarily of investment banking and other transaction fees, employee severance
and relocation costs as well as the write-off of deferred financing costs
related to the former credit facilities replaced by the OEI Credit Facility in
March 1998. All such costs were paid in 1998. See "-- Liquidity and Capital
Resources."

     Income tax provision (benefit). An income tax benefit of $209.7 million (of
which $3.8 million is a current provision and $213.5 million is a deferred
benefit) was recognized for 1998, compared to a provision of $41.0 million (of
which $6.2 million was a current provision and $34.8 million was a deferred
provision) for 1997. Current taxes include a $3.6 million non-cash provision
representing current taxes incurred in Cote d'Ivoire which, under the terms of
the production sharing contract, will be paid by the Ivorian government from
their production proceeds. During the fourth quarter, the Company determined
that a valuation allowance would be required relating to the probability that
certain NOLs would expire in 1999 unutilized. As such, a valuation allowance of
$4.5 million was recorded as of December 31, 1998. The deferred tax benefit for
1998 is further impacted by the non-cash write-down of oil and gas properties
and the tax treatment of certain merger costs, a portion of which is not
deductible for tax purposes. Consistent with Statement of Financial Accounting
Standards (SFAS) No. 109, Accounting for Income Taxes, the deferred income tax
provision or benefit was derived primarily from changes in deferred income tax
assets and liabilities recorded on the balance sheet.

     Net income (loss). Due to the factors described above, the net loss for
1998 was $406.9 million, a decrease of $449.8 million from net income of $42.9
million for 1997.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

     Operating revenues. The Company's total operating revenues increased
approximately $156.4 million, or 40%, to $552.2 million for the year ended
December 31, 1997, from $395.8 million for the comparable period in 1996.
Production levels for the year ended December 31, 1997, increased 41% to 33,699
MBOE from 23,904 MBOE for the comparable period in 1996. The increase in oil and
gas revenues is due to increased oil volumes in the Gulf of Mexico Region and
Equatorial Guinea, resulting from a full year's production from the Central Gulf
Properties and Block B in Equatorial Guinea ("Block B") and higher U.S. gas
volumes.

     Oil revenues increased 43% to $335.1 million, the result of significantly
increased worldwide production volumes offset by a drop in the average realized
price received. Oil production increased 57% to 18,078 MBbls in 1997 due
primarily to increased oil production in the Gulf of Mexico Region and
Equatorial Guinea. The average sales price before hedging for oil decreased 13%
to $18.54 in 1997 compared to 1996.

     Natural gas revenues increased 33% to $214.1 million, the result of slight
increases in natural gas prices and the impact of certain hedging activities,
offset by certain property sales. The average sales price before hedging for
natural gas remained constant at $2.30 per Mcf in 1997 and 1996. Natural gas
production for 1997 was 93,723 MMcf, an increase of 26% over 1996 volumes due
primarily to acquisitions and increased production in the Gulf of Mexico Region,
Cote d'Ivoire and Canada, offset by property sales and natural production
declines in North America.

     For the year ended December 31, 1997, the Company's total revenues were
further affected by a $1.3 million decrease in hedging revenues. In order to
manage its exposure to price risks in the sale of its oil and natural gas, the
Company from time to time enters into price hedging arrangements. The Company's
average sales prices including hedging for oil and natural gas for the year
ended December 31, 1997 were $18.54 per Bbl and $2.28 per Mcf compared with
$20.24 per Bbl and $2.18 per Mcf in the prior period.

     Production costs. For the year ended December 31, 1997, total production
costs were $124.4 million, as compared to $98.4 million in the 1996 period, an
increase of 26%. This increase primarily results from fluctuations in normal
operating expenses, including operating expenses associated with increased
production from new facilities and an increase of approximately $11.8 million
relating to production costs of the Central Gulf Properties acquired in 1996.
Production and operating costs (costs incurred to operate and maintain wells and
related equipment, excluding ad valorem and production taxes) decreased to $3.02
per BOE for the year ended December 31, 1997, from $3.26 per BOE in the
comparable 1996 period. This decrease is primarily the result of increased
production in the Company's offshore Gulf of Mexico Region and Equatorial Guinea
fields, which have substantial fixed operating costs due to the capital
intensive nature of the facilities, further impacted by the under-utilization of
capacity in the Gulf of Mexico Region fields.

                                       19

<PAGE>   22


     General and administrative expenses. For the year ended December 31, 1997,
general and administrative expenses were $30.2 million as compared to $27.4
million in the comparable 1996 period, an increase of 10%. This increase is
primarily due to costs of increased corporate staffing associated with both an
increase in drilling activities and the Company's acquisitions in 1996 and 1997.
In addition, a new systems implementation partially offset by an increase in
1997 in the capitalization of a portion of the salaries paid to employees
directly engaged in the acquisition, exploration and development of oil and gas
properties in accordance with the full cost method of accounting contributed to
the increase. General and administrative expenses per BOE decreased to $0.90 per
BOE for the year ended December 31, 1997, from $1.14 per BOE for the comparable
1996 period. This unit decrease is primarily the result of increased production
in the Gulf of Mexico Region and Equatorial Guinea fields.

     Depreciation, depletion and amortization expense. For the year ended
December 31, 1997, DD&A expense was $248.4 million as compared to $147.6 million
in the comparable 1996 period, an increase of 68%. This variance can primarily
be attributed to the Company's increased production and related current and
future capital costs from the 1996 and 1997 Gulf of Mexico Region and
international drilling programs and acquisitions, partially offset by the
increase in proved reserves resulting from such programs and acquisitions. On a
BOE basis, oil and gas DD&A for the year ended December 31, 1997, was $7.23 per
BOE as compared to $6.06 per BOE for the year ended December 31, 1996. This unit
increase is primarily the result of increased production in the Gulf of Mexico
Region and Equatorial Guinea fields.

     Interest and debt expense. For the year ended December 31, 1997, interest
and debt expense increased 20% to $49.1 million, from $40.8 million in the
comparable 1996 period. This increase is primarily the result of an increase of
approximately $11.5 million from the comparable 1996 period relating to the 
9 3/4% Notes issued in September 1996 and interest and debt expense of
approximately $8.9 million related to the issuance of $200 million of the 8 7/8%
Notes in July 1997. In addition, interest and debt expense increased in both
periods due to a higher average balance on the Company's bank credit facilities.
The increase was partially offset by a decrease in interest expense of
approximately $7.0 million as a result of the Company's purchase of $124.8
million of the $125.0 million in original principal amount of the Company's 
13 1/2% Senior Notes due 2004 (the "Existing Senior Notes") on July 22, 1997,
and by an increase in the amount of interest capitalized in the 1997 period
resulting from an increase in the Company's unevaluated assets, including
additional acreage and seismic data.

     Income tax expense (benefit). An income tax provision of $41.0 million (of
which $6.2 million is a current provision and $34.8 million is a deferred
provision) was recognized for 1997, compared to a provision of $26.2 million (of
which $0.8 million was a current provision and $25.4 million was a deferred
provision) for 1996. A significant portion of current taxes in 1997 is a $4.6
million non-cash provision representing current taxes incurred in Cote d'Ivoire
which, under the terms of the production sharing contract, will be paid by the
Ivorian government from their production proceeds. Consistent with SFAS No. 109,
Accounting for Income Taxes, the deferred income tax provision was derived
primarily from changes in deferred income tax assets and liabilities recorded on
the balance sheet. The 1996 deferred tax provision was affected by the use of
$13.0 million of net operating loss ("NOL") carryforwards to essentially
eliminate 1996 taxable income and the deferred tax effect of exercised stock
options. At December 31, 1997, the Company had $122.7 million of U.S. NOL
carryforwards, $67.0 million of Equatorial Guinea NOL carryforwards and $32.2
million of Canadian federal tax pools. The Company paid cash income taxes in
1997 and 1996 of $1.8 million and $0.4 million, respectively, to several states,
Canada and the U.S.

     Extraordinary loss on early extinguishment of debt. On July 22, 1997, the
Company purchased approximately $124.8 million of the $125.0 million original
principal amount of the Existing Senior Notes for approximately $151.5 million.
This repurchase resulted in an after-tax extraordinary charge of $19.3 million,
representing the difference between the purchase price and the net carrying
value of the Existing Senior Notes.

     Net income. Due to the factors described above, net income before an
extraordinary charge for the year ended December 31, 1997, increased to $62.2
million, an increase of $7.2 million or 13% from net income of $55.0 million for
the comparable 1996 period. Including the effect of the extraordinary charge,
the Company recorded net income of $42.9 million for the year ended December 31,
1997.

</TABLE>

     For the year ended December 31, 1998, net cash provided by operating
activities decreased by $107.5 million, or 32% as compared to the year ended
December 31, 1997, resulting primarily from the precipitous drop in the price of
oil and gas experienced during the year and the $39.0 million in nonrecurring
merger costs.

     Cash used in investing activities during the year ended December 31, 1998,
increased to $970.7 million, as compared to $803.7 million for 1997. This
increase relates primarily to the Company's exploration and development project
expenditures.

     Financing activities during the year ended December 31, 1998, generated
cash of $737.5 million as compared to $415.0 million in the comparable 1997
period, resulting from increased incurrences of long-term debt, including bank
debt and the $500.0 million offering of Senior and Senior Subordinated Notes,
and the issuance of the $50.0 million of Series A Preferred Stock.

     Capital requirements. The Company's capital investments to date have
focused primarily on exploration, acquisitions and development of proved
properties. The Company's expenditures for property acquisition, exploration and
development for the years ended December 31, 1998, 1997 and 1996:

</TABLE>

     The Company makes, and will continue to make, substantial capital
expenditures for the acquisition, exploration, development, production and
abandonment of its oil and natural gas reserves. The Company has historically
funded its operations, acquisitions, exploration and development expenditures
from cash flows from operating activities, bank borrowings, sales of equity and
debt securities, sales of non-strategic oil and natural gas properties, sales of
partial interests in exploration concessions and project finance borrowings.

     Due to the current pricing environment, the Company's stand-alone capital
expenditure budget for 1999 is expected to decrease to approximately $150.0
million focused on the Company's three operating regions. In addition, the
Company will evaluate its level of capital spending throughout the year based
upon drilling results, commodity prices, cash flows from operations and property
acquisitions. Actual capital spending may vary from the capital expenditure
budget.

     Upon the closing of the merger with Seagull, the capital budgets of the
Company and Seagull will be modified, and the combined total is expected to be
approximately $400.0 to $500.0 million for 1999. In addition, the credit
facilities of the Company and Seagull will be combined and initial discussions
with certain banks have indicated that

                                       21

<PAGE>   24


the gross available credit will be approximately $800.0 million. See "Business
and Properties -- Recent Developments."

     The Company's debt to total capitalization ratio increased to 78.5% at
December 31, 1998, from 48.1% at December 31, 1997. The Company's interest
coverage ratio (calculated as the ratio of income from operations plus DD&A and
impairment of proved oil and gas properties to reported interest expense plus
capitalized interest less non-cash amortization of debt issue costs) was 3.8 to
1 for 1998 compared with 6.8 to 1 for 1997. The Company plans to pursue
additional property sales in 1999 to pay down amounts outstanding under the
Credit Facility as a means of improving this ratio.

     Concurrent with the closing of the Merger on March 27, 1998, the Company
entered into a $750.0 million five-year unsecured revolving credit facility (OEI
Credit Facility) which combined and replaced the Company's and UMC's existing
credit facilities. The OEI Credit Facility, which is with a group of commercial
banks, provides for various borrowing options under either a base rate or
Eurodollar margin rates and provided a $600.0 million initial borrowing base.
Borrowings against the facility were repaid in July 1998 with the proceeds from
a $500.0 million Notes Offering made by the Company pursuant to Rule 144A, which
notes were subsequently exchanged for publicly-traded instruments with identical
terms. At that time, the credit facility was amended and restated to a $400.0
million, five-year revolving credit facility with an initial borrowing base of
$300.0 million. On November 10, 1998, the Company received commitments to
increase the borrowing base under the facility to $400.0 million. As of December
31, 1998, total borrowings outstanding against the facility were approximately
$357.0 million, leaving approximately $43.0 million of available credit. In
February 1999, the Company put in place a $20.0 million facility, primarily to
support certain outstanding letters of credit.

     The OEI Credit Facility contains certain financial and ratio covenants. The
Company's financial results through December 31, 1998 did not comply with one of
these covenant tests. This event of noncompliance, and subsequent application of
this covenant, was waived by the lenders until the Company's planned merger with
Seagull or the September 30, 1999 reporting date. The Company has planned and
potential asset sales and other financing opportunities believed available which
could be used to achieve compliance with this covenant. Accordingly, the Company
believes it is probable it will comply with this covenant throughout 1999. The
amount outstanding under the OEI Credit Facility has been classified as
long-term in the accompanying December 31, 1998 balance sheet.

     On November 10, 1998, the Company completed a private placement of 50,000
shares of Series A Convertible Preferred Stock for $38.0 million of oil and gas
properties and $12.0 million in cash from one of its institutional investors.
The Series A shares have a 6.5% cumulative dividend payable semi-annually
beginning April 1, 1999.

     In addition to developing its existing reserves, the Company attempts to
increase its reserve base, production and operating cash flow by engaging in
strategic acquisitions of oil and gas properties. In order to finance other
possible future acquisitions, the Company may seek to obtain additional debt or
equity financing. The availability and attractiveness of these sources of
financing will depend upon a number of factors, some of which will relate to the
financial condition and performance of the Company, and some of which will be
beyond the Company's control, such as prevailing interest rates, oil and gas
prices and other market conditions. There can be no assurance that the Company
will acquire any additional producing properties. In addition, the ability of
the Company to incur additional indebtedness and grant security interests with
respect thereto will be subject to the terms of the Indentures governing the
Company's public debt and the OEI Credit Facility, while the ability of the
Company to grant certain liens will be subject to the terms of the Indentures.

     Liquidity. The Company currently expects that its cash flow from
operations, proceeds from asset dispositions and availability under the OEI
Credit Facility will be adequate to execute its 1999 business plan. However, no
assurance can be given that the Company will not experience liquidity problems
from time to time in the future or on a long-term basis. There can be no
assurance that the Company will be successful in its proposed asset
dispositions. If the Company's cash flow from operations, proceeds from asset
dispositions and availability under the OEI Credit Facility are not sufficient
to satisfy its cash requirements, there can be no assurance that additional debt
or equity financing will be available to meet its requirements, especially in
light of the Company's existing leverage and the state of the applicable capital
markets.

     Effects of Leverage. The Company has outstanding long-term indebtedness of
approximately $1,371.9 million as of December 31, 1998. The Company's level of
indebtedness has several important effects on its future operations,

                                       22

<PAGE>   25


including (i) a substantial portion of the Company's cash flow from operations
must be dedicated to the payment of interest on its indebtedness and will not be
available for other purposes, (ii) the covenants contained in the various
indentures require the Company to meet certain financial tests, and contain
other restrictions which limit the Company's ability to borrow additional funds
or to dispose of assets and may affect the Company's flexibility in planning
for, and reacting to, changes in its business, including possible acquisition
activities and (iii) the Company's ability to obtain additional financing in the
future for working capital, expenditures, acquisitions, general corporate
purposes or other purposes may be impaired. None of the indentures place
significant restrictions on a wholly-owned subsidiary's ability to make
distributions to the parent company.

     The Company's ability to meet its debt service obligations and to reduce
its total indebtedness will be dependent upon the Company's future performance,
which will be subject to oil and gas prices, general economic conditions and to
financial, business and other factors affecting the operations of the Company,
many of which are beyond its control. There can be no assurance that the
Company's future performance will not be adversely affected by such economic
conditions and financial, business and other factors.

OTHER MATTERS

     Price fluctuations and volatile nature of markets. Despite the measures
taken by the Company to attempt to control price risk, the Company remains
subject to price fluctuations for natural gas and oil sold on the spot market.
Prices received for natural gas sold on the spot market are volatile due
primarily to seasonality of demand and other factors beyond the Company's
control. Domestic oil prices generally follow worldwide oil prices which are
subject to price fluctuations resulting from changes in world supply and demand.
Any significant decline in prices for oil and gas could have a material adverse
effect on the Company's financial position, results of operations and quantities
of reserves recoverable on an economic basis.

     Environmental. The Company's business is subject to certain federal, state,
and local laws and regulations relating to the exploration for, and the
development, production and transportation of, oil and natural gas, as well as
environmental and safety matters. Many of these laws and regulations have become
more stringent in recent years, often imposing greater liability on a larger
number of potentially responsible parties. Although the Company believes it is
in substantial compliance with all applicable laws and regulations, the
requirements imposed by such laws and regulations are frequently changed and
subject to interpretation, and the Company is unable to predict the ultimate
cost of compliance with these requirements or their effect on its operations.
Under certain circumstances, the MMS may require any Company operations on
federal leases to be suspended or terminated. Any such suspensions, terminations
or inability to meet applicable bonding requirements could materially and
adversely affect the Company's financial condition and operations. Although
significant expenditures may be required to comply with governmental laws and
regulations applicable to the Company, to date such compliance has not had a
material adverse effect on the earnings or competitive position of the Company.
It is possible that such regulations in the future may add to the cost of
operating offshore drilling equipment or may significantly limit drilling
activity.

     The OPA imposes ongoing requirements on a responsible party 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 $10.0 million depending on gross
tonnage. With respect to offshore facilities, proof of greater levels of
financial responsibility may be applicable. This amount is subject to upward
regulatory adjustment up to $150.0 million.

     Year 2000 compliance. Historically, most computer systems, including
microprocessors embedded into field equipment and other machinery, utilized
software that recognized a calendar year by its last two digits. Beginning in
the year 2000, these systems will require modification to recognize a calendar
year by four digits.

     Accordingly, the Company has initiated a comprehensive plan to address the
year 2000 issues associated with its operations and business. OEI's board has
been briefed about the year 2000 problem generally and as it may affect OEI. The
board has assigned its Audit Committee to oversee the adoption and
implementation of a year 2000 plan. A committee of senior executives has been
created to develop a plan and manage its implementation. The aim of the plan is
to take reasonable steps to prevent OEI's mission-critical functions from being
impaired due to the year 2000 problem.

                                       23
<PAGE>   26
    The plan includes several phases - (a) assessment of all of the Company's
systems and technology; (b) implementation and testing of modifications to or
replacements of existing systems and technology, both financial and operational;
(c) communication with key business partners; and (d) contingency planning.

     In planning and developing the project, OEI has considered both its
information technology ("IT") and its non-IT systems. The term "computer
equipment and software" includes systems that are commonly thought of as IT
systems, including accounting, data processing, telephone systems, scanning
equipment, and other miscellaneous systems. Those items not considered IT
technology include alarm systems, metering devices, monitors for field
operations, and other miscellaneous systems. Both IT and non-IT systems may
contain embedded technology, which complicates OEI's year 2000 identification,
assessment, remediation, and testing efforts. Based upon its identification and
assessment efforts to date, OEI is in the process, where necessary, of
reprogramming or replacing the computer equipment and software it currently uses
to become year 2000 compliant. In addition, the Company's primary information
systems are in the process of being replaced with fully compliant new systems as
part of a regularly scheduled upgrade to meet the Company's growing capacity and
performance requirements. The testing of the systems under consideration should
be completed by April 1999.

     The Company is utilizing both internal and external resources to reprogram,
or replace, and test much of its IT systems, primarily financial and operational
software, for necessary modifications identified in its assessment of year 2000
issues. As of the date of this filing, the Company estimates that approximately
60% of its year 2000 plan for these IT systems has been implemented and
anticipates that the remainder of the plan, including any necessary remedial
action, will be completed by June 30, 1999. During July 1998, the Company began
utilizing internal and external resources to evaluate its vulnerability to year
2000 issues related to its non-IT systems, primarily field operational systems
and equipment. The Company has also initiated formal communications with all of
its key business partners to determine the extent to which the Company is
vulnerable to those third parties' potential failure to remediate their own year
2000 issues. The evaluation of non-IT systems and communications with key
business partners is well underway, and the Company estimates that the remainder
of the year 2000 plan concerning these areas will be completed by June 1999.

     The Company is currently in the process of developing contingency plans for
both financial and operational systems. OEI's contingency plans are being
designed to minimize the disruptions or other adverse effects resulting from
year 2000 incompatibilities regarding these systems, and to facilitate the early
identification and remediation of year 2000 problems that first manifest
themselves after January 1, 2000.

     The failure to correct a material year 2000 issue could result in an
interruption in, or a failure of, certain normal business activities, thereby
having a material, adverse effect on the Company's results of operations,
liquidity and financial position. The Company's remediation efforts are expected
to significantly reduce the Company's level of uncertainty about year 2000
compliance and the possibility of interruptions of normal operations. However,
there can be no guarantee that the systems of other companies, on which the
Company's systems rely, will be timely converted, or that a failure to convert
by another company, or a conversion that is incompatible with the Company's
systems, would not have a material adverse effect on the Company. Disruptions to
the oil and gas transportation networks controlled by third-party carriers could
result in reduced production volumes delivered to market. In addition, risks
association with foreign operations may increase with the uncertainty of year
2000 compliance by foreign governments and their supporting infrastructures.

     The total costs for the year 2000 compliance review, evaluation, assessment
and remediation efforts are not expected to be in excess of $1,000,000. Of this
amount, approximately $200,000 had been incurred as of December 31, 1998.

     The costs of these projects and the dates on which the Company plans to
complete modifications and replacements are based on management's best
estimates, which were derived utilizing numerous assumptions of future events
including the continued availability of certain resources, third party
modification plans and other factors. However, there can be no guarantee that
these estimates will be achieved and actual results could differ materially from
those plans.

the Notes to Consolidated Financial Statements, are "forward-looking
statements", within the meaning of Section 21E of the Securities Exchange Act of
1934, that are subject to certain events, risk and uncertainties that may be
outside the Company's control. These forward-looking statements include
statements of management's plans and objectives for the Company's future
operations and statements of future economic performance, information regarding
the Seagull Merger, information regarding drilling schedules, expected or
planned production or transportation capacity, future production levels of
international and domestic fields, the Company's capital budget and future
capital requirements, the Company's meeting its future capital needs, the
Company's realization of its deferred tax assets, the level of future
expenditures for environmental costs and the outcome of regulatory and
litigation matters, and the assumptions described in this report underlying such
forward-looking statements. Actual results and developments could differ
materially from those expressed in or implied by such statements due to a number
of factors, including, without limitation, those described in the context of
such forward-looking statements, fluctuations in the price of crude oil and
natural gas, the success rate of exploration efforts, timeliness of development
activities, risk incident to the drilling and completion for oil and gas wells,
future production and development costs, the political and economic climate in
which the Company conducts operations and the risk factors described from time
to time in the Company's other documents and reports filed with the Securities
and Exchange Commission.

ITEM 7.a.  QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

     Energy swap agreements. The Company engages in futures contracts with
certain of its production through master swap agreements (Swap Agreements). The
Company considers these futures contracts to be hedging activities and, as such,
monthly settlements on these contracts are reflected in oil and gas sales. In
order to consider these futures contracts as hedges, (i) the Company must
designate the futures contract as a hedge of future production and (ii) the
contract must reduce the Company's exposure to the risk of changes in prices.
Changes in the market value of futures contracts treated as hedges are not
recognized in income until the hedged item is also recognized in income. If the
above criteria are not met, the Company will record the market value of the
contract at the end of each month and recognize a related gain or loss. Proceeds
received or paid relating to terminated contracts or contracts that have been
sold are amortized over the original contract period and reflected in oil and
gas sales. The Company enters into hedging activities in order to secure an
acceptable future price relating to a portion of future production. The primary
objective of these activities is to protect against decreases in price during
the term of the hedge.

     The Swap Agreements provide for separate contracts tied to the New York 
Mercantile Exchange (NYMEX) light sweet oil and natural gas futures contracts.
The Company has contracts which contain specific contracted prices (Swaps) that
are settled monthly based on the differences between the contract prices and the
average NYMEX prices for each month applied to the related contract volumes. To
the extent the average NYMEX price exceeds the contract price, the Company pays
the spread, and to the extent the contract price exceeds the average NYMEX price
the Company receives the spread. In addition, the Company has combined contracts
which have agreed upon price floors and ceilings (Costless Collars). To the
extent the average NYMEX price exceeds the contract ceiling, the Company pays
the spread between the ceiling and the average NYMEX price applied to the
related contract volumes. To the extent the contract floor exceeds the average
NYMEX price, the Company receives the spread between the contract floor and the
average NYMEX price applied to the related contract volumes. Under the terms of
the Swap Agreements, certain counterparties have extended the Company a $5.0
million line of credit for use in conjunction with its hedging activities. As of
December 31, 1998, the Company had no outstanding oil or natural gas Swaps and
the fair market value of the natural gas Costless Collars was approximately $7.3
million.

     As of December 31, 1998, the Company's open forward position on its
outstanding natural gas Costless Collars was as follows:

     The Company currently has no outstanding hedging arrangements and it
intends to commit no more than 50% of its production on a BOE basis to such
arrangements at any point in time. A portion of the Company's oil and natural
gas production will be subject to price fluctuations unless the Company enters
into additional hedging transactions.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Board of Directors of
Ocean Energy, Inc.:

     We have audited the accompanying consolidated balance sheets of Ocean
Energy, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1998
and 1997 and the related consolidated statements of income, cash flows and
changes in stockholders' equity 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 Ocean Energy, Inc. 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.

                               OCEAN ENERGY, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 ORGANIZATION

     The accompanying consolidated financial statements of Ocean Energy, Inc.
(OEI or the Company), a Delaware corporation, have been prepared pursuant to the
rules and regulations of the Securities and Exchange Commission (SEC).

     The Company is an independent energy company engaged in the exploration,
development, production and acquisition of oil and natural gas offshore Gulf of
Mexico, across North America and in the oil and natural gas producing regions of
Cote d'Ivoire, Equatorial Guinea, Pakistan, Bangladesh, Angola and the Republic
of Yemen.

     Effective March 27, 1998, pursuant to the Agreement and Plan of Merger
dated December 22, 1997, United Meridian Corporation (UMC) was merged into the
Company (the Merger). As a result of the Merger, each outstanding share of UMC
common stock was converted into 1.3 shares of OEI common stock with
approximately 46 million shares issued to the shareholders of UMC representing
approximately 46% of all of the issued and outstanding shares of OEI. The
Company's shareholders received 2.34 shares of OEI common stock for each share
outstanding immediately preceding the Merger representing approximately 54% of
all of the issued and outstanding shares of OEI. The Merger was accounted for as
a pooling of interests. Accordingly, the accompanying consolidated financial
statements for periods prior to the Merger have been restated to combine the
historical results of OEI and UMC. All common share data throughout these
financial statements have been restated to reflect the impact of the respective
stock splits resulting from the Merger.

     On November 24, 1998, OEI and Seagull Energy Corporation (Seagull) entered
into a merger agreement that provides for a stock-for-stock merger (Seagull
Merger) of OEI with and into Seagull. In connection with the Seagull Merger OEI
stockholders will receive one share of common stock of Seagull for each existing
outstanding share of OEI. Seagull will amend its Articles of Incorporation to
change its name to Ocean Energy, Inc. (New Ocean). After the Seagull Merger, the
stockholders of OEI will own approximately 61.5% of the outstanding common stock
of New Ocean and the shareholders of Seagull will own the remaining 38.5% of the
outstanding common stock of New Ocean. The Seagull Merger is expected to qualify
as a tax-free transaction and is subject to each Company's stockholders'
approval and certain other conditions. The transaction will be treated as a
purchase business combination for accounting purposes and is anticipated to
close by the end of the first quarter of 1999.

NOTE 2  SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its majority-owned affiliates. Interests in joint ventures, limited
liability companies and partnerships are accounted for under the proportional
consolidation method. All significant intercompany balances and transactions
have been eliminated in consolidation.

     The consolidated financial statements reflect all adjustments that, in the
opinion of management, are necessary for a fair presentation.

     Certain reclassifications of amounts previously reported have been made to
conform to current year presentation.

CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments with an original
maturity of three months or less when purchased to be cash equivalents.

INVENTORY

     The Company conducts a portion of its oil and gas activities with a small
group of institutional and corporate investors. In connection therewith, the
Company periodically acquires oil and gas properties with the intention of
selling a portion of its interests to such investors or industry partners. To
the extent those properties are to be resold, costs are carried as a current
asset and classified as inventory. No gain or loss is recognized on inventoried
properties. 


                                       34
<PAGE>   37

At December 31, 1998 and 1997, costs of properties to be resold included in
inventory were not significant. The remaining inventory consists of tubular
goods and other equipment.

OIL AND GAS PROPERTIES

     The Company's exploration and production activities are accounted for under
the full cost method. Under this method, all acquisition, exploration and
development costs, including certain related employee costs and a portion of
interest expense, incurred for the purpose of finding oil and gas are
capitalized. Such amounts include the cost of drilling and equipping productive
wells, dry hole costs, lease acquisition costs, delay rentals and costs related
to such activities. Employee costs associated with production operations and
general corporate activities are expensed in the period incurred. Transactions
involving sales of reserves in place, unless unusually significant, are recorded
as adjustments to oil and gas properties. Capitalized costs are limited to the
sum of the present value of future net revenues using current unescalated
pricing discounted at 10%, related to estimated production of proved reserves
and the lower of cost or estimated fair value of unevaluated properties, all net
of expected income tax effects.

     Depreciation, depletion and amortization of oil and gas properties is
computed on a country-by-country basis using a unit-of-production method based
on estimated proved reserves. All costs associated with evaluated oil and gas
properties, including an estimate of future development, restoration,
dismantlement and abandonment costs associated therewith, are included in the
computation base. A majority of the oil and gas reserves are estimated
periodically by independent petroleum engineers. The Company evaluates all
unevaluated oil and gas properties on a quarterly basis to determine if any
impairment has occurred or if the property has been otherwise evaluated. If a
property has been evaluated, or if there is determined to be any impairment,
costs related to the particular unevaluated properties are reclassified as an
evaluated oil and gas property, and thus subject to amortization if there are
proved reserves associated with the related cost center. Otherwise, such
impairment will be recognized in the period in which it occurs. At June 30,
1998, the Company recognized a non-cash impairment of oil and gas properties in
the amount of $218.4 million pre-tax ($135.4 million after-tax) pursuant to this
ceiling limitation required by the full cost method of accounting for oil and
gas properties. The Company recognized an additional write-down at December 31,
1998, in the amount of $321.5 million pre-tax ($199.3 million after tax). The
write-downs were primarily the result of the precipitous decline in world crude
oil and natural gas prices experienced during 1998.

OTHER PROPERTY AND EQUIPMENT

     Other property consists primarily of furniture, office equipment, leasehold
improvements and computers. The majority of these assets are depreciated on a
straight-line basis with estimated useful lives ranging from three to seven
years.

GAS IMBALANCES

     The Company follows the entitlements method of accounting for gas
imbalances. Under this method, the Company records as revenue only that portion
of gas production sold and allocable to its ownership interest in the related
well. Imbalance payables are recorded at historical amounts and imbalance
receivables are valued at the lower of (i) the price in effect at the time of
production, (ii) the current market value or (iii) the contract price net of
selling expenses. Gas imbalances arise when a purchaser takes delivery of more
or less gas volume from a well than the Company's actual interest in the
production from that well. Such imbalances are reduced either by subsequent
recoupment of over-and-under deliveries or by cash settlement, as required by
applicable contracts. Under-deliveries are included in Other assets and
over-deliveries are included in Deferred credits and other liabilities.

HEDGING

     The Company periodically enters into contracts in order to hedge against
the volatility of oil and gas prices. The Company enters into such transactions
for the purpose of managing the overall impact of commodity price volatility.
These transactions generally take the form of swaps or price collars, and are
placed with major financial institutions. The results of such transactions are
included as Oil or Gas sales in the Consolidated Statement of Income as the
related production volumes are sold.



                                       35
<PAGE>   38

     The Company enters into interest rate hedge contracts from time to time
with major financial institutions. These transactions are made to protect
against higher future interest costs on the Company's floating rate long-term
debt. The results of interest rate hedges are included in Interest and debt
expense on the Consolidated Statement of Income.

FEDERAL INCOME TAXES

     The Company follows the provisions of Statement of Financial Accounting
Standards (SFAS) No. 109, Accounting for Income Taxes, under which deferred tax
assets or liabilities are estimated at the financial statement date based upon
(i) temporary differences between the tax basis of assets and liabilities and
their reported amounts in the financial statements and (ii) net operating loss
and tax credit carryforwards for tax purposes.

EARNINGS PER SHARE

     The Company adopted SFAS No. 128, Earnings Per Share, during the fourth
quarter of 1997. In accordance with this new pronouncement, basic earnings per
share is computed by dividing net income (loss) available to common stockholders
by the weighted average number of common shares outstanding during the period.
Diluted earnings per share is determined on the assumption that outstanding
stock options have been converted using the average price for the period. For
purposes of computing earnings per share in a loss year, common stock
equivalents have been excluded from the computation of weighted average common
shares outstanding because their effect is antidilutive. Prior period amounts
have been restated in accordance with the requirements of the pronouncement.

STATEMENT OF CASH FLOWS

     Cash flows from operating activities for 1998, 1997 and 1996, include cash
payments for interest of $54.8 million, $49.6 million, and $42.9 million and
income taxes of $0.3 million, $1.8 million and $0.4 million, respectively.

FOREIGN CURRENCY TRANSLATION

     The United States (U.S.) dollar is the functional currency for all
international locations except for Canada, which uses the Canadian dollar. The
financial position and results of operations attributable to the Company's
Canadian operations are translated into U.S. currency in accordance with SFAS
No. 52, Foreign Currency Translation. Accordingly, the assets and liabilities of
the financial statements are translated using the currency exchange rate in
effect at the balance sheet date while the revenues, expenses, gains and losses
are translated using the exchange rate for the periods in which they occurred.
The effects of such translations are reflected as adjustments to stockholders'
equity as shown in the Consolidated Statement of Changes in Stockholders' Equity
and are included as a component of Comprehensive Income.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period.
Actual results could differ from those estimates.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 131, Disclosures about Segments of an Enterprise and Related Information.
This statement requires a company to report financial information by operating
segment. Operating segments are defined as the basis on which the chief
operating decision maker disaggregates the company for making operating
decisions and assessing performance. The Company, which has one reportable
segment, adopted the provisions of SFAS No. 131 and has included geographic
information in Notes 15 and 16 to the Consolidated Financial Statements.

     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which establishes a new model for accounting
for derivatives and hedging activities. SFAS 133, which will be effective for
the Company's fiscal year 2000, requires that all derivatives be recognized in
the balance sheet as either assets or liabilities and measured at fair value.
The statement also requires that changes in fair value be reported in earnings


                                       36
<PAGE>   39

unless specific hedge accounting criteria are met. The Company is currently
evaluating the effect of the adoption of the Statement on its consolidated
financial position and results of operations.

     Of the $488,689 of net unproved property costs (primarily seismic and lease
acquisition costs) at December 31, 1998, being excluded from the amortizable 
base, $299,795 was incurred in 1998, $134,930 was incurred in 1997, $40,927 was 
incurred in 1996 and $13,037 was incurred in prior years. The majority of the 
costs will be evaluated over a five-year period.


     As part of its on-going operations, the Company continually sells producing
and undeveloped reserves and related assets. Significant acquisitions and
dispositions for the three years ending December 31, 1998 are discussed below.

1998 TRANSACTIONS

     On September 15, 1998, the Company acquired additional contract interests
in certain production sharing contracts in Cote d'Ivoire for a net purchase
price of $20.2 million.

     On November 10, 1998, the Company completed the acquisition of incremental
interests in several North American oil and gas properties in which it already
owned a working interest. The properties were acquired from John Hancock Mutual
Life Insurance Company for a net purchase price of $38.0 million. The
acquisition was financed through the issuance of Series A Convertible Preferred
Stock (see Note 6).

     In December 1998, the Company completed its acquisition of certain contract
interests in Angola for $38.6 million and in Yemen for $5.0 million.

     Merger costs of $39.0 million relating to the Company's merger with UMC
were recorded in the first quarter of 1998. These costs consist primarily of
investment banking and other transaction fees, employee severance and relocation
cots as well as the write-off of deferred financing costs related to the former
credit facilities replaced by the OEI Credit Facility in March 1998. All such
costs were paid in 1998.

1997 TRANSACTIONS

     On March 7, 1997, the Company completed an acquisition of certain interests
in various state leases in the Main Pass Block 69 field (the Main Pass
Acquisition), offshore Plaquemines Parish, Louisiana, for a net purchase price
of $55.9 million. The Main Pass Acquisition included interests situated
contiguous to the Company's existing Main Pass 69 holdings acquired from Shell
Oil Company, its affiliates and subsidiaries (Shell) in June 1992.

     On October 15, 1997, the Company acquired certain oil and gas interests in
various federal leases in the South Pass 61 and 65 fields (the South Pass
Properties) from Shell for a net purchase price of $59.9 million. The Company
acquired a 50% working interest in the fields and became operator of the
properties. The acquisition included interests in 95 producing wells located on
approximately 26,250 gross acres. Also on October 15, 1997, the Company entered
into an exploratory joint venture agreement with Shell which establishes an Area
of Mutual Interest (AMI) covering approximately 240 square miles located in
coastal and offshore areas of Plaquemines Parish, Louisiana. Under the terms of
the oil and gas exploration agreement, the Company and Shell have agreed to
contribute existing leasehold, project inventory and proprietary 3-D seismic
data within the AMI.

     In 1997, the Company acquired additional interests in various properties it
operates and in which it holds an existing working interest position from
several of its institutional partners. The net cost of the additional interests
acquired from the Company's institutional partners was approximately $49.6
million. In addition, the Company acquired interests in other North American
properties for total consideration of $13.0 million.

     During 1997, the Company sold additional non-strategic North American
properties for total proceeds of $19.4 million.

1996 TRANSACTIONS

     On September 26, 1996, the Company acquired from Mobil Oil and Producing
Southeast, Inc. (Mobil), certain interests in eleven oil and gas producing
fields and related production facilities primarily situated in the shallow
federal waters of the central Gulf of Mexico, offshore Louisiana (the Central
Gulf Properties), for approximately $117.6 million. At December 31, 1996, one of
the eleven Central Gulf Properties was included in Inventory. The subject
property was sold on January 3, 1997, for $37.2 million. No gain or loss was
recognized on the sale.

     In 1995, the Company agreed to assign to Yukong Limited a portion of its
interests in Blocks CI-01 and CI-02 in Cote d'Ivoire and Blocks B, C and D in
Equatorial Guinea. Mobil Equatorial Guinea, Inc. subsequently exercised its
preferential right to purchase the interest in Block B in lieu of the proposed
assignment to Yukong Limited. Under the agreements, the Company received $40.1
million in cash in 1996 and 1995.

     In June 1996, Ocean Energy Resources Canada, Ltd. (Resources), the
Company's wholly-owned Canadian subsidiary, sold all of its interest in the
Rocanville area in the province of Saskatchewan, effective May 1, 1996. Net
proceeds from the sale were $6.7 million.

     In September 1996, the Company executed an agreement with Shell Exploration
Africa B.V. to sell a 55% contract interest in Block CI-105 in Cote d'Ivoire for
total cash proceeds of $3.3 million, including $0.9 million relating to
reimbursement of certain exploration costs.

     During 1996, the Company sold various other non-strategic North American
properties for total proceeds of $22.1 million.

NOTE 4 RESTRICTED DEPOSITS

     The Company, as the operator of certain oil and gas properties, is a party
to two escrow agreements. The first, related to its interest in the East Bay
Fields, requires monthly deposits until the escrow account equals $40.0 million.
The second agreement, related to its interest in the Main Pass 69 field,
required an initial deposit of $250,000 and monthly deposits thereafter until
the escrow account equals $7.5 million. These deposits are to provide for the
future plugging and abandonment costs associated with the oil and gas
properties. Such funds are restricted as to withdrawal by the agreements. With
respect to any specifically planned plugging and abandoning operation, funds are
partially released when the Company presents to the escrow agent the planned
plugging and abandoning operations approved by the applicable governmental
agency, with the balance released upon the presentation by the Company to the
escrow agent of evidence from the governmental agency that the operation was
conducted in compliance with applicable laws and regulations. The escrow agent
for both agreements is an unrelated financial institution. As of December 31,
1998 and 1997, the escrow balances were approximately $10.8 million and $8.5
million, respectively. The Company is currently in negotiations to release the
escrow balances.

</TABLE>

OEI CREDIT FACILITY

     Concurrent with the closing of the Merger on March 27, 1998, the Company
entered into a $750.0 million five-year unsecured revolving credit facility (OEI
Credit Facility) which provided for a $600.0 million initial borrowing base and
which combined and replaced both the Revolving Credit Facility and the Global
Credit Facility discussed below. The OEI Credit Facility, which is with a group
of commercial banks, provides for various borrowing options under either a base
rate or Eurodollar margin rates. Total borrowings outstanding against the
facility were repaid in July 1998 with the proceeds from a $500.0 million Notes
Offering, discussed below, made by the Company pursuant to Rule 144A. At that
time, the OEI Credit Facility was restated and amended to a $400.0 million,
five-year revolving credit facility, with an initial borrowing base of $300.0
million. In November 1998, the borrowing base was increased to $400.0 million.
As of December 31, 1998, total borrowings outstanding against the OEI Credit
Facility were approximately $357.0 million, leaving approximately $43.0 million
of available credit. In February 1999, the Company put in place a $20.0 million
facility, primarily to support certain outstanding letters of credit.

     The OEI Credit Facility contains certain financial and ratio covenants. The
Company's financial results through December 31, 1998 did not comply with one of
these covenant tests. This event of noncompliance, and subsequent application of
this covenant, was waived by the lenders until the Company's planned merger with
Seagull or the September 30, 1999 reporting date. The Company has planned and
potential asset sales and other financing opportunities believed available which
could be used to achieve compliance with this covenant. Accordingly, the Company
believes it is probable it will comply with this covenant throughout 1999. The
amount outstanding under the OEI Credit Facility has been classified as
long-term in the accompanying December 31, 1998 balance sheet.

NOTES OFFERING

     On July 8, 1998, the Company closed an offering of $500.0 million Senior
and Senior Subordinated Notes receiving net proceeds of approximately $487.8
million, after deducting underwriting discounts and expenses. The 


                                       40
<PAGE>   43

offering, made pursuant to Rule 144A, comprised three separate indentures
including $125.0 million of 7 5/8% Senior Notes due July 1, 2005, $125.0 million
of 8 1/4% Senior Notes due July 1, 2018, and $250.0 million of 8 3/8% Senior
Subordinated Notes due July 1, 2008. The proceeds from the offering were used to
pay off amounts then outstanding under the OEI Credit Facility at the closing of
the offering. The excess net proceeds of the offering over the amounts
outstanding under the OEI Credit Facility have since been used for capital
expenditures and general corporate purposes. On September 21, 1998, the Company
filed a registration statement on Form S-4 with the SEC to exchange the Notes
for publicly-traded instruments with identical terms. Such exchange offer was
completed on October 23, 1998.

REVOLVING CREDIT FACILITY

     The Revolving Credit Facility was a three-year $250.0 million facility with
a $200.0 million borrowing base, maturing on October 31, 2000.

     At the Company's option, borrowings under the Revolving Credit Facility
bore interest either at the base rate (the higher of the federal funds rate plus
0.5% per annum or the Agent's prime commercial lending rate) or the London
Interbank Offered Rate (LIBOR), in the latter case plus an applicable margin of
125 to 175 basis points, depending upon the percentage of usage on the Revolving
Credit Facility.

GLOBAL CREDIT FACILITY

     As of January 1997, the Global Credit Facility provided a borrowing base
amount of $200.0 million. In November 1997, the borrowing base was increased to
$300.0 million.

     During 1997 and 1996, the Global Credit Facility provided the Company with
various interest rate options based upon prime and LIBOR rates.

13 1/2% SENIOR NOTES

     On December 7, 1994, in conjunction with the OEI initial public offerings,
the Company completed an offering of $125.0 million of 13 1/2% Senior Notes due
December 1, 2004 (the 13 1/2% Notes). Interest was payable semi-annually on June
1 and December 1 of each year, commencing June 1, 1995. On July 22, 1997, the
Company amended the indenture governing its 13 1/2% Notes and purchased
approximately $124.8 million of the $125.0 million in original principal amount
of the 13 1/2% Notes for approximately $151.5 million. This purchase resulted in
an extraordinary charge of $19.3 million, net of a deferred tax benefit of $11.6
million. The extraordinary charge represented the difference between the
purchase price and related expenses and the net carrying value of the 13 1/2%
Notes.

10 3/8% SENIOR SUBORDINATED NOTES

     On October 30, 1995, the Company completed a public offering of $150.0
million of 10 3/8% Senior Subordinated Notes (10 3/8% Notes) due 2005 at an
initial price of 99.5% of face value. Proceeds of $144.9 million (after
deducting underwriting discounts, commission and expenses of the offering) were
used to reduce debt under the Global Credit Facility. Interest is payable
semi-annually on April 15 and October 15 of each year, commencing April 15,
1996. The 10 3/8% Notes are general unsecured senior obligations of the Company
and are guaranteed by Ocean Louisiana, but are subordinate to the OEI Credit
Facility. The 10 3/8% Notes are redeemable at the option of the Company, in
whole or in part, at any time after October 15, 2000 at certain premiums to face
value.

9 3/4% SENIOR SUBORDINATED NOTES

     On September 26, 1996, the Company completed the offering of $160.0 million
of 9 3/4% Senior Subordinated Notes due 2006 (9 3/4% Notes) at a discount for
net proceeds of approximately $154.0 million (after offering costs). Interest on
the 9 3/4% Notes is payable semi-annually on April 1 and October 1 of each year.
The 9 3/4% Notes are general unsecured senior obligations of the Company and are
guaranteed by Ocean Louisiana, but are subordinate to the OEI Credit Facility.
Proceeds to the Company were used primarily to complete the acquisition of the
Central Gulf Properties.

<PAGE>   44



8 7/8% SENIOR SUBORDINATED NOTES

     On July 2, 1997, the Company completed the offering of $200.0 million of
8 7/8% Senior Subordinated Notes due 2007 (8 7/8% Notes) at a discount for
proceeds of approximately $195.2 million (after offering costs). Interest is
payable semi-annually on January 15 and July 15 of each year. The 8 7/8% Notes
are general unsecured senior obligations of the Company and are guaranteed by
Ocean Louisiana, but are subordinate to the OEI Credit Facility. Proceeds to the
Company were used primarily to finance the purchase of the 13 1/2% Notes and to
repay outstanding indebtedness under the Revolving Credit Facility.

OTHER LONG-TERM DEBT

     Havre Pipeline Company LLC, a limited liability corporation in which the
Company had a 58% interest at December 31, 1998, entered into a credit agreement
(Havre Credit Agreement) which provided a Term Loan due September 30, 2005. The
Company's proportionate share outstanding at December 31, 1998 is $6.5 million,
including current maturities. A new credit agreement was executed in January,
1999. The term note has a three-year draw down period and a ten-year payment
schedule with payments required quarterly. Additional principal payments may be
required under the Havre Credit Agreement if operating cash flows of the limited
liability corporation exceed predetermined levels. The Havre Credit Agreement is
currently guaranteed by a subsidiary of the Company.

OTHER DISCLOSURES

     Effective January 18, 1994, the Company entered into five-year fixed LIBOR
interest rate swap contracts that provided for fixed interest rates to be
realized on notional amounts of $45.0 million from 1995 through 1998. The
agreement included varying annual fixed interest rates ranging from 3.66% in
1994 to 6.40% in 1998, plus interest rate margins. In 1995 and 1996, the Company
had in place a two-year LIBOR interest rate cap contract on an additional
notional amount of $45.0 million at interest rate caps of 7.60% and 8.30%,
respectively, plus interest rate margins. The contracts expired in January,
1999.

NOTE 6  CAPITAL STOCK

     In 1997, the Company adopted a shareholder rights plan (the Rights Plan),
pursuant to which preferred stock purchase rights (the Rights) have been
distributed to holders of the Company's common stock. The Rights Plan is
designed to deter coercive takeover tactics and to prevent an acquirer from
attempting to gain control of the Company without negotiating with the Board of
Directors. The Company is not aware of any effort to acquire control of the
Company, but adopted the Rights Plan concurrently with its execution of the
Agreement and Plan of Merger with UMC.

     The Rights will expire on December 22, 2007. The Rights will be exercisable
only if a person acquires beneficial ownership of 15 percent or more of the
Company's common stock (an Acquiring Person), or commences a tender offer which
would result in ownership of 15 percent or more of such stock. Under the Rights
Plan, one Right to purchase one one-hundredth of a share of a new series of
junior preferred stock of the Company at an exercise price of $240.00 per one
one-hundredth of a share (subject to adjustment) was issued for each outstanding
share of the Company's common stock held at the close of business on January 9,
1998 (the Record Date).

     Under certain circumstances, the Rights "flip in" and enable the holders
(other than an Acquiring Person) to buy the Company's common stock at a 50
percent discount. Under other circumstances, the Rights "flip over" and entitle
the holders (other than an Acquiring Person) to buy shares of the acquirer's
common stock at a 50 percent discount.

     The Company will generally be entitled to redeem the Rights in whole, but
not in part, at $0.001 per Right payable in cash or common stock, subject to
adjustment, at any time until 10 business days (subject to extension) after the
first public announcement that an Acquiring Person has become such.

     The Company has authorized 250,000,000 shares of common stock, 8,000,000
shares of preferred stock and 2,000,000 shares of junior preferred stock.

     The following table summarizes the calculation of annual weighted average
common shares outstanding for purposes of the computations of earnings per share

     As of December 31, 1998 and 1997, the Company and its subsidiaries had U.S.
federal net operating loss (NOL) carryforwards of approximately $193.0 million
and $122.7 million, respectively, and Equatorial Guinea NOL carryforwards of
approximately $137.6 million and $67.0 million, respectively. The Company's
Canadian subsidiary also had $55.1 million and $32.2 million in Canadian Tax
Pool carryforwards as of December 31, 1998 and 1997, respectively.

     The Company is subject to taxation under the laws of Cote d'Ivoire,
Equatorial Guinea and other foreign jurisdictions. Income taxes in these
jurisdictions will be taken as a credit or deduction against the Company's
United States tax liability.

     A valuation allowance is provided for that portion of a tax asset for which
it is deemed more likely than not that it will not be realized. Due to the
recent decrease in oil and gas prices, management provided a $4.5 million
valuation allowance for the deferred tax asset related to the NOL that will
expire in 1999. The Company has recognized a deferred tax asset relating to the
remaining NOL carryforwards. The U.S. federal NOLs expire as follows (in
thousands):

     For federal income tax purposes, certain limitations are imposed on an
entity's ability to utilize its NOLs in future periods if a change of control,
as defined for federal income tax purposes, has taken place. In general terms,
the limitation on utilization of NOLs and other tax attributes during any one
year is determined by the value of an acquired entity at the date of the change
of control multiplied by the then-existing long-term, tax-exempt interest rate.
The manner of determining an acquired entity's value has not yet been addressed
by the Internal Revenue Service. The Company has determined that, for federal
income tax purposes, a change of control occurred as a result of the stock
purchases made by the Company's shareholders, and future utilization of NOLs
will be limited in the manner described above. The use of NOLs acquired as a
result of corporate acquisitions were already subject to limitations computed at
the time of each acquisition. While the effect of such limitations may be to
defer the use of existing NOL carryforwards, the Company does not believe such
limitations will significantly impact the Company's ability to utilize the NOLs.

     As of December 31, 1997, the Company and its subsidiaries had investment
tax credit carryforwards of approximately $1.0 million. The amount of investment
tax credit carryfowards at December 31, 1998, was not significant. To the extent
not utilized, these carryforwards will expire in the years 1998 through 2001.
For purposes of computing the net deferred tax liability as of December 31,
1997, none of these carryforwards were utilized.

     The plans provide that directors, officers and key employees may be awarded
options to purchase Common Stock of the Company at a price equal to the market
value of OEI Common Stock on the award date. New options granted will vest over
a three-year period. As a result of the Merger, virtually all options
outstanding became fully vested and are exercisable by the optionees. On
November 23, 1998, the Company cancelled options which had been issued during
fiscal year 1998 under the Long Term Incentive Plan for Non-Executive Employees
and reissued them at an option price which reflected current market value of the
Company's stock as of that date. No compensation expense was recognized by the
Company for fiscal year 1998 as a result of the transaction. The following table
reflects summarized information about stock options outstanding at December 31,
1998:

     The Company accounts for these plans under Accounting Principles Board 
Opinion (APB) Opinion No. 25, Accounting for Stock Issued to Employees, under
which no compensation cost has been recognized. Had compensation cost for these
plans been determined consistent with SFAS 123, Accounting for Stock-Based
Compensation, the Company's reported net income (loss) and earnings (loss) per
share would have been adjusted to the following pro forma amounts (in thousands,
except per share amounts):

     The fair value of each option is estimated on the date of grant using the
Black-Scholes option pricing model, with the following assumptions used for
grants in 1998, 1997 and 1996, respectively; risk-free interest rates of 4.73%
to 5.75%, 6.16% to 6.83%, and 5.40% to 6.76%; expected dividend yields of 0%, 0%
and 0%; expected lives of 5.0 years to 6.5 years, 5.0 years to 6.5 years and 5.0
years to 6.5 years; and expected volatility of 61.03%, 42.67% to 54.13%, and
39.34% to 43.14%. Under SFAS 123, the acceleration of vesting of options due to
the Merger resulted in the recognition of all remaining unamortized compensation
expense relating to those options.

RESTRICTED STOCK

     On November 24, 1998, the Company, under its 1998 Long Term Incentive Plan,
awarded a total of 560,000 shares of restricted stock with a fair market value
of $10.25 per share to six executive officers at no cost to the employees. The
stock will vest over a period of three years and any unvested shares must be
forfeited in the event employment is terminated for any reason other than death,
disability or retirement. Upon a change in control of the Company any unvested
shares automatically become vested and all restrictions lapse. The Company
accounts for this stock in accordance with APB Opinion No. 25.

SAVINGS PLAN

     The Company maintains defined contribution savings plans for the benefit of
its U.S. employees. During 1998, 1997 and 1996, the Company made contributions
to the Plans on behalf of all participants totaling $2.3 million, $1.6 million
and $1.3 million, respectively.

     Resources maintains a separate group savings plan for its employees. During
1998, 1997 and 1996, this subsidiary contributed $73,000, $76,000, and $67,000,
respectively, to the Plan for the benefit of its employees.

NOTE 9  MAJOR CUSTOMERS

     The Company markets its oil and gas production to numerous purchasers under
a combination of short and long-term contracts. During 1998, 1997 and 1996,
Shell Oil Company accounted for 12%, 21% and 28%, respectively, of the Company's
oil and gas revenues. Mobil Sales and Supply Corporation accounted for 15% of
the Company's oil and gas revenues in 1998 and 1997 as the purchaser of the
Company's production in Equatorial Guinea. During 1998, 1997 and 1996, the
Company had no other purchasers that accounted for greater than 10% of its oil
and gas revenues. The Company believes that the loss of any single customer
would not have a material adverse effect on the results of operations of the
Company.

NOTE 10 COMMITMENTS AND CONTINGENCIES

     The Company, as working interest owner, is responsible for payment of its
share of plugging and abandonment costs on its properties. As of December 31,
1998, the total future abandonment costs on the Company's oil and gas properties
estimated to be incurred were approximately $156.5 million. The estimates of
plugging and abandonment costs and their timing may change due to many factors
including, among others, actual production results, inflation rates, and changes
in environmental laws and regulations.

     In August 1993, the Minerals Management Service (MMS) provided notice to
lessees of Outer Continental Shelf (OCS) leases that new levels of lease and
area wide bonds would be required effective November 26, 1993, in connection
with the plugging and abandoning of wells located offshore and the removal of
all production facilities. The coverage is designed to reflect an appropriate
balance between encouraging the maximum economic recovery of oil and natural gas
from federal offshore leases while providing the federal government an adequate
level of protection in the event the lessee defaults on its obligations to
properly abandon lease wells and remove platforms and other structures from the
property.

     The MMS requires lessees of OCS properties to post bonds in connection with
the plugging and abandonment of wells located offshore and the removal of all
production facilities. Operators in the OCS waters of the Gulf of Mexico are
currently required to post area wide bonds of $3.0 million or $500,000 per
producing lease and supplemental bonds at the discretion of the MMS. The Company
has posted with the MMS an area wide bond of $3.0 million and in 1998 became
exempt from supplemental bonding requirements. The Company does not anticipate
that the cost of any such bonding requirements will materially affect the
Company's financial position. Under certain circumstances, the MMS may require
any Company operations on federal leases to be suspended or terminated. Any such
suspensions or terminations could have a material adverse effect on the
Company's financial condition and operations. The MMS also intends to adopt
financial responsibility regulations under the Oil Pollution Act of 1990 (OPA).
The OPA regulations 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 an 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 regulation. If the party fails to report a spill or to 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 a responsible party, 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 $10.0 million depending
on gross tonnage. With respect to offshore facilities, proof of greater levels
of financial responsibility may be applicable. This amount is subject to upward
regulatory adjustment up to $150.0 million.

     The Company has entered into operating leases for office space and
equipment for which $3.6 million, $3.1 million, and $1.9 million, in rental
expense has been included in the accompanying financial statements for the years
ended December 31, 1998, 1997 and 1996, respectively. Future minimum rental
payments required for the years ending December 31, 1999 through 2003 are $3.0
million, $3.1 million, $3.4 million, $3.4 million and $3.6 million,
respectively.

     Resources has an agreement with Nova Corporation, a natural gas pipeline
company, to transport specified quantities of natural gas. Future minimum
transportation expense payments required for years ending December 31, 1999
through 2003 are $0.9 million, $0.6 million, $0.5 million, $0.3 million and $0.3
million, respectively.

     The Company has entered into agreements for transportation of specified
quantities of natural gas across Canada for sales to the Great Lakes region.
Future minimum transportation expense payments required for years ending
December 31, 1999 through 2003 are $5.4 million, $3.0 million, $3.0 million,
$2.8 million, and $1.6 million, respectively.

NOTE 11 RELATED PARTY TRANSACTIONS

     The Company currently conducts a portion of its oil and gas activities in
conjunction with a group of institutional and corporate investors that
participate in certain of the Company's acquisition, development and exploration
programs, and provide the Company with certain carried interests and management
fees. Management fee income of $3.0 million, $3.0 million and $1.8 million,
related to the years ended December 31, 1998, 1997 and 1996, respectively, is
included in the Consolidated Statement of Income.

     During 1998, 1997 and 1996, the Company paid $0.8 million, $1.5 million and
$1.4 million, respectively, to an affiliate of a stockholder associated with an
overriding royalty interest owned by it.

     In 1996, the Company executed agreements with various entities controlled
by two former directors of UMC covering coventures in Pakistan, Bangladesh and
possible other international exploration opportunities.

     Effective November 1, 1995, the Company entered into a consulting agreement
for geological services with a party related to an officer of the Company. The
original term of this agreement expired on October 31, 1997, and the term was
extended such that the new expiration date of the agreement was October 31,
1999. In 1998, 1997, and 1996, the Company paid $134,823, $107,952, and
$110,565, respectively, relating to the agreement.

     All transactions with the aforementioned entities are under normal industry
terms and conditions.

NOTE 12 LITIGATION AND CLAIMS

     The U.S. Environmental Protection Agency has indicated that the Company may
be potentially responsible for costs and liabilities associated with alleged
releases of hazardous substances at two sites in Louisiana under the
Comprehensive Environmental Response, Compensation and Liability Act. Given the
extremely large number of companies that have been identified as potentially
responsible for releases of hazardous substances at the sites and the small
volume of hazardous substances allegedly disposed of by the companies whose
properties the Company acquired, management believes that the Company's
potential liability arising from these sites, if any, will not have a material
adverse impact on the Company.

     In February 1998, the Tulane Environmental Law Clinic (Clinic), claiming to
represent several southeastern Louisiana environmental groups, gave notice that
it intends to file a Clean Water Act citizens' suit against the Company after a
sixty-day waiting period expires in connection with the discharge of produced
water in East Bay. The Clinic claims that the Company is violating the Clean
Water Act by discharging produced water from its East Bay Central Facilities
into Southwest Pass, and has stated that it will seek an injunction to require
the Company to cease its discharge of produced water, and will seek civil
penalties and attorney's fees. If the Clinic were to successfully obtain an
injunction, certain production operations at the Company's East Bay Facilities
could be interrupted until favorable resolution of the issue in court or
accelerated completion of the Company's plan to reformat operations to provide
for alternative produced water disposal. The Company believes that its zero
discharge compliance plan, which permits the temporary continued discharge of
produced water into Southwest Pass through July 1, 1999, is completely lawful as
authorized by a Compliance Order issued by the Louisiana Department of
Environmental Quality, and intends to vigorously defend any such citizens' suit,
if filed. The Clinic has delivered similar notices to other Louisiana coastal
producers.

     The Company is a named defendant in lawsuits and is a party in governmental
proceedings from time to time arising in the ordinary course of business. While
the outcome of such lawsuits or other proceedings against the Company cannot be
predicted with certainty, management does not expect these matters to have a
material adverse effect on the financial position or results of operations of
the Company.

NOTE 13 CREDIT RISK AND PRICE PROTECTION AGREEMENTS

TRADE RECEIVABLES AND PAYABLES

     Substantially all of the Company's accounts receivable at December 31,
1998, result from oil and gas sales and joint interest billings to other
companies in the oil and gas industry and institutional partners. This
concentration of customers and joint interest owners may impact the Company's
overall credit risk, either positively or negatively, in 


                                       49
<PAGE>   52

that these entities may be similarly affected by industry-wide changes in
economic or other conditions. Receivables from oil and gas sales are generally
not collateralized. Credit losses incurred by the Company on receivables
generally have not been significant in prior years.

OIL AND GAS MARKET HEDGES

     The Company's revenues are primarily the result of sales of its oil and
natural gas production. Market prices of oil and natural gas fluctuate and may
adversely affect operating results. To mitigate this risk, the Company has, from
time to time, entered into oil and natural gas price hedging contracts to reduce
its exposure to price reductions on its production. These transactions have been
entered into with major financial institutions, thereby minimizing credit risk.

     The Company hedges certain of its production through master swap agreements
(Swap Agreements). The Company considers these futures contracts to be hedging
activities and, as such, monthly settlements on these contracts are reflected in
oil and gas sales. In order to consider these futures contracts as hedges, (i)
the Company must designate the futures contract as a hedge of future production
and (ii) the contract must reduce the Company's exposure to the risk of changes
in prices. Changes in the market value of futures contracts treated as hedges
are not recognized in income until the hedged item is also recognized in income.
If the above criteria are not met, the Company will record the market value of
the contract at the end of each month and recognize a related gain or loss.
Proceeds received or paid relating to terminated contracts or contracts that
have been sold are amortized over the original contract period and reflected in
oil and gas sales. The Company enters into hedging transactions for the purpose
of securing a price for a portion of future production that is acceptable at the
time the transaction is entered into. The primary objective of these activities
is to protect against decreases in price during the term of the hedge.

     The Swap Agreements provide for separate contracts tied to the New York
Mercantile Exchange (NYMEX) light sweet oil and natural gas futures contracts.
The Company has contracts which contain specific contracted prices (Swaps) that
are settled monthly based on the differences between the contract prices and the
average NYMEX prices for each month applied to the related contract volumes. To
the extent the average NYMEX price exceeds the contract price, the Company pays
the spread, and to the extent the contract price exceeds the average NYMEX price
the Company receives the spread. In addition, the Company has combined contracts
which have agreed upon price floors and ceilings (Costless Collars). To the
extent the average NYMEX price exceeds the contract ceiling, the Company pays
the spread between the ceiling and the average NYMEX price applied to the
related contract volumes. To the extent the contract floor exceeds the average
NYMEX price, the Company receives the spread between the contract floor and the
average NYMEX price applied to the related contract volumes. Under the terms of
the Swap Agreements, certain counterparties have extended the Company a $5
million line of credit for use in conjunction with its hedging activities. As of
December 31, 1998, the Company had no outstanding oil or natural gas Swaps and
the fair market value of the natural gas Costless Collars was approximately $7.3
million.

     As of December 31, 1998, the Company's open forward position on its
outstanding natural gas Costless Collars was as follows:

</TABLE>

     These Collars were cancelled in January 1999, resulting in net proceeds of
$6.9 million. The Company currently has no outstanding hedging arrangements.

     The results of hedging increased (decreased) natural gas and oil revenues
by $24.5 million, ($1.3) million and ($22.6) million for the years ended
December 31, 1998, 1997 and 1996, respectively.

NOTE 16 DISCLOSURE OF OIL AND GAS OPERATIONS (UNAUDITED)

PROVED RESERVES

     Substantially all reserve estimates presented herein were prepared by
either Ryder Scott Company, Netherland, Sewell & Associates, Inc., or McDaniel &
Associates Consultants Ltd., independent petroleum engineers. The Company
cautions that there are many uncertainties inherent in estimating proved reserve
quantities, in projecting future production rates and in the timing of future
development expenditures. In addition, reserve estimates of new discoveries are
more imprecise than those of properties with a production history. Accordingly,
these estimates are subject to change as additional information becomes
available.

     Proved oil and gas reserves are the estimated quantities of oil,
condensate, natural gas and natural gas liquids that geological and engineering
data demonstrate with reasonable certainty to be recoverable in future years
from known reservoirs under existing economic and operating conditions. Proved
developed oil and gas reserves are those reserves expected to be recovered
through existing wells with existing equipment and operating methods.

     Information presented for the Company's international locations relates to
contract interests held in multiple production sharing contracts between the
Company, its joint venture partners and the governments of Cote d'Ivoire and
Equatorial Guinea. The Company has no ownership interest in the oil and gas
reserves but does have the right to share revenues and/or production and is
entitled to recover most field and other operating costs. The reserve estimates
are subject to revision as prices fluctuate due to the cost recovery feature
under the production sharing contract.

     Net quantities of proved reserves and proved developed reserves of oil
(including condensate and natural gas liquids) and natural gas, as well as the
changes in proved reserves during the periods indicated, are set forth in the
tables below:

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS

    The following table sets forth the standardized measure of the discounted
future net cash flows attributable to the Company's proved oil and gas reserves.
Future cash inflows were computed by applying year-end prices of oil and gas to
the estimated future production of proved oil and gas reserves. Gas prices were
escalated only where existing contracts contained fixed and determinable
escalation clauses. Contractually provided gas prices in excess of estimated
market clearing prices were used in computing the future cash inflows only if
the Company expects to continue to receive higher prices under legally
enforceable contract terms. Future prices actually received may differ from the
estimates in the standardized measure.

     Future production and development costs represent the estimated future
expenditures (based on current costs) to be incurred in developing and producing
the proved reserves, assuming continuation of existing economic conditions.
Future income tax expenses were computed by applying statutory income tax rates
to the difference between pre-tax net cash flows relating to the Company's
proved oil and gas reserves and the tax basis of proved oil and gas properties.
In addition, the effects of statutory depletion in excess of tax basis,
available net operating loss carryforwards and investment tax credit
carryforwards were used in computing future income tax expense. The resulting
annual net cash inflows were then discounted using a 10% annual rate (in
thousands):

NOTE 17  SUPPLEMENTAL GUARANTOR INFORMATION

     Ocean Louisiana, the Company's only direct subsidiary, has unconditionally
guaranteed the full and prompt performance of the Company's obligations under
the 10 3/8% Notes, the 13 1/2%, the 9 3/4% Notes and the 8 7/8% Notes and
related indentures, including the payment of principal, premium (if any) and
interest. None of the referenced indentures places significant restrictions on a
wholly-owned subsidiaries' ability to make distributions to the parent. Other
than intercompany arrangements and transactions, the consolidated financial
statements of Ocean Louisiana are equivalent in all material respects to those
of the Company and therefore the separate consolidated financial statements of
Ocean Louisiana are not material to investors and have not been included herein.
However, in an effort to provide meaningful financial data relating to the
guarantor (i.e., Ocean Louisiana on an unconsolidated basis), the following
condensed consolidating financial information has been provided following the
policies set forth below:

     (1) Investments in subsidiaries are accounted for by the Company on the
         cost basis. Earnings of subsidiaries are therefore not reflected in the
         related investment accounts.

     (2) Certain reclassifications were made to conform all of the financial
         information to the financial presentation on a consolidated basis. The
         principal eliminating entries eliminate investments in subsidiaries and
         intercompany balances.

     Certain intercompany notes and the related accrued interest were
transferred from the Company to a newly formed non-guarantor subsidiary
effective as of January 1, 1997.

                               AMENDMENT NO. 1 TO
                              EMPLOYMENT AGREEMENT

         This Amendment No. 1 (this "Amendment") to that certain Employment

         WHEREAS, the Company anticipates entering into an Agreement and Plan of
Merger with Seagull Energy Corporation, a Texas corporation ("Seagull"),

to amend certain provisions of the Employment Agreement, with all such
amendments to be effective as of the consummation of the Merger, except the
amendment to Section 7(b) of the Employment Agreement which shall be effective
as of the Amendment Date;

representations, warranties and agreements contained in this Amendment, and for
other valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties agree as follows: 

         1. Upon the consummation of the Merger, Section 2 of the Employment
Agreement shall be amended by adding the following sentence at the end of such
section:

                  "Furthermore, notwithstanding any other sentence of this
                  Section 2, Employee shall retire as an employee of the Company
                  (the "Retirement") effective as of the consummation of the
                  merger of the Company with and into Seagull Energy Corporation
                  ("Seagull"), with Seagull being the surviving corporation (the
                  "Surviving Company," and the transaction being referred to as
                  the "Merger") at which time the retirement shall be treated as
                  a resignation for Good Reason pursuant to Section 7(e)
                  hereof."

                  expiration of Employee's term as member of the Board of
                  Directors of the Surviving Company, a position to which he is
                  to be elected effective as of the consummation of the Merger,
                  the Surviving Company agrees to use its reasonable best
                  efforts to cause Employee to be re-elected or re-appointed as
                  member of the Board of Directors of the Surviving Company for
                  a three year term."

         3. Upon the consummation of the Merger, Section 6 of the Employment
Agreement shall be amended by adding the following sentence at the end of such
section:

                  "The Surviving Company agrees to amend the Company's
                  Supplemental Benefit Plan (the "SBP") to permit up to
                  twenty-two percent (22%) of any payments made under clause (A)
                  of Section 7(c) hereof to be deferrable under the SBP. In the
                  event of a Termination, the Company agrees, if necessary, to
                  provide for the establishment of a rabbi trust for the
                  accounts covered by the SBP in the event of a change in
                  control. In addition, the Surviving Company also agrees to
                  amend the SBP to provide for the establishment of a rabbi
                  trust for the accounts covered by the SBP in the event of a
                  Change in Control. A "Change in Control" for purposes of the
                  preceding sentence shall occur if (i) the Surviving Company
                  shall not be the surviving entity in any merger or
                  consolidation (or survives only as a subsidiary of another
                  entity), (ii) the Surviving Company sells all or substantially
                  all of its assets to any other person or entity (other than a
                  wholly-owned subsidiary), (iii) the Surviving Company is to be
                  dissolved and liquidated, or (iv) as a result of or in
                  connection with a contested election for the members of the
                  Board of Directors of the Surviving Company such that the
                  members constituting the Board of Directors of the Surviving
                  Company immediately following the consummation of the Merger
                  shall cease to constitute a majority of the Board of Directors
                  of the Surviving Company."

         4. As of the Amendment Date, Section 7(b) of the Employment Agreement
is deleted in its entirety and replaced with the following:

                  "(b) Death. If Employee's employment is terminated due to his
                  death, Employee's spouse or estate, as the case may be, shall
                  receive the same compensation and benefits set forth in
                  Section 7(c)(i)."

         5. Upon the consummation of the Merger, Section 7(c)(i) of the
Employment Agreement is deleted in its entirety and replaced with the following:

                  "(i) The Surviving Company may terminate this Agreement and
                  Employee's employment for any reason deemed sufficient by the
                  Surviving Company upon notice as provided in Section 10.
                  However, in the event that Employee's employment is terminated
                  during the Term by the Surviving Company for any reason other
                  than his Misconduct or Disability (as such terms are defined
                  below), then, subject to Section 7(h) below: (A) within five


                                       2

<PAGE>   3


                  business days of the Date of Termination, the Surviving
                  Company shall pay to Employee a lump sum amount in cash equal
                  to three times the sum of (1) Employee's Base Compensation and
                  (2) Employee's Target Bonus; (B) for the 36-month period after
                  such Date of Termination, the Surviving Company, at its sole
                  expense, shall continue to provide or arrange to provide
                  Employee (and Employee's dependents) with health insurance
                  benefits no less favorable than the health plan benefits
                  provided by the Surviving Company (or any successor) during
                  such 36-month period to any senior executive officer of the
                  Surviving Company (including after Employee's death if it
                  occurs at the beginning of or during the 36-month period);
                  provided, further, to the extent the coverage or benefits
                  received are taxable to Employee, the Surviving Company shall
                  make Employee "whole" on a net after tax basis; (C) on the
                  Date of Termination all then outstanding Company or Surviving
                  Company stock-based awards of Employee, whether under this
                  Agreement, a Company or Surviving Company stock plan or
                  otherwise, shall become immediately exercisable and payable in
                  full, as the case may be, with any performance goals
                  associated therewith being deemed to have been achieved at the
                  maximum levels; (D) for the 36-month period after the Date of
                  Termination, the Surviving Company shall pay, at a monthly
                  rate of $6,250 for Employee's office rent, expenses,
                  secretarial assistance, computers, and parking; (E) for the
                  36-month period after the Date of Termination, the Surviving
                  Company shall continue to pay for the same club dues and
                  Company related expenses of Employee for which the Surviving
                  Company is paying on the Date of Termination, and, (F) in the
                  case of Retirement only, and contingent upon continued service
                  on the Board of Directors of the Surviving Company or the
                  Surviving Company's successor, the Surviving Company shall
                  grant Employee a stock option covering 25,000 shares of
                  Surviving Company stock on terms and conditions substantially
                  similar to those granted to outside directors on March 27,
                  1998 under the Company's 1998 Long Term Incentive Plan.
                  Notwithstanding anything in this Agreement to the contrary, if
                  any payment to Employee in respect of a Company or Surviving
                  Company stock-based award would give rise to a short-swing
                  profit liability to Employee under Section 16(b) of the
                  Securities Exchange Act of 1934, then both the payment and the
                  entitlement to payment thereof shall automatically be deferred
                  until the earliest date at which the payment of such benefit
                  would not result in a short-swing profit liability to

                               AMENDMENT NO. 1 TO
                              EMPLOYMENT AGREEMENT


         This Amendment No. 1 (this "Amendment") to that certain Employment
Agreement entered into effective as of March 27, 1998, by and between Ocean
Energy, Inc., a Delaware corporation ("Company"), and James C. Flores
("Employee," and such employment agreement, the "Employment Agreement") is
entered into as of November 24, 1998 (the "Amendment Date") between the Company
and Employee.

         WHEREAS, the Company anticipates entering into an Agreement and Plan of
Merger with Seagull Energy Corporation, a Texas corporation ("Seagull"),
pursuant to which the Company will merge with and into Seagull, with Seagull
being the surviving corporation (the "Merger"); and

         WHEREAS, in anticipation of the Merger, the Company and Employee desire
to amend certain provisions of the Employment Agreement, with all such
amendments to be effective as of the consummation of the Merger, except the
amendment to Section 7(b) of the Employment Agreement which shall be effective
as of the Amendment Date;

         NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained in this Amendment, and for
other valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties agree as follows:

         1. Upon the consummation of the Merger, Section 3 of the Employment
Agreement is deleted in its entirety and replaced with the following:

                           "3. Employee's Duties. During the Term, Employee
                  shall serve as the Chairman of the Board of Directors of
                  Seagull Energy Corporation, the surviving corporation of the
                  merger between the Company and Seagull Energy Corporation (the
                  "Surviving Company"), with such customary duties and
                  responsibilities as may from time to time be assigned to him
                  by the Board, provided that such duties are at all times
                  consistent with the duties of such position. Employee shall
                  report directly to the Board.

                           Employee agrees to devote his full attention and time
                  during normal business hours to the business affairs of the
                  Surviving Company and to use reasonable best efforts to
                  perform faithfully and efficiently such duties and
                  responsibilities. Notwithstanding the foregoing, during the
                  Term Employee may engage in the following activities so long
                  as they do not interfere in any material respect with the
                  performance of Employee's duties and responsibilities
                  hereunder: (i) serve on corporate, civic or charitable boards
                  or committees, (ii) deliver lectures, fulfill speaking
                  engagements or teach on a part-time basis at educational



<PAGE>   2



                  institutions, and (iii) manage his personal investments
                  including, but not limited to, Sable Minerals, Inc., a
                  Louisiana corporation; provided, however, in no event shall
                  the conduct of any of such activities by Employee be deemed to
                  materially interfere with Employee's duties hereunder until
                  Employee has been notified in writing thereof by the Board and
                  given a reasonable period in which to cure such interference."

         2. As of the Amendment Date, Section 7(b) of the Employment Agreement
is deleted in its entirety and replaced with the following:

                  "b. Death. If Employee's employment is terminated due to his
                  death, Employee's spouse or estate, as the case may be, shall
                  receive the same compensation and benefits set forth in
                  Section 7(c)(i)."

         3. Upon the consummation of the Merger, Section 7(e) of the Employment
Agreement is amended by deleting the word "or" after paragraph (v), and
inserting the word "or" and the following paragraph after paragraph (vi):

                  "(vii) A material breach of any provision of this Agreement by
                  the Surviving Company."

         4. Capitalized terms used in this Amendment, but not otherwise defined,
shall have the meanings ascribed in the Employment Agreement.

         5. Unless otherwise expressly modified by this Amendment, all terms and
conditions set forth in the Employment Agreement shall remain in full force and
effect. The parties acknowledge that the only terms and conditions modified by
this Amendment are those expressly set forth herein.

         6. The validity, interpretation, construction and performance of this
Amendment shall be governed by the laws of the State of Texas without reference
to rules relating to conflicts of law.

         7. This Amendment may be executed in one or more counterparts, each of
which shall be deemed to be an original, but all of which together will
constitute one and the same instrument.

                               AMENDMENT NO. 1 TO
                         SEVERANCE PROTECTION AGREEMENT


         This Amendment No. 1 (this "Amendment") to that certain Severance
Protection Agreement, dated as of December 20, 1997, by and among United
Meridian Corporation, UMC Petroleum Company (a wholly-owned subsidiary of United

protection agreement, the "Severance Protection Agreement") is entered into as
of November 24, 1998 (the "Amendment Date") between Executive and Ocean Energy,

         WHEREAS, the obligations of the Severance Protection Agreement were
assumed by the Company by operation of law in connection with the merger of the
Company and United Meridian Corporation;

         WHEREAS, the Company anticipates entering into an Agreement and Plan of
Merger with Seagull Energy Corporation, a Texas corporation ("Seagull"),
pursuant to which the Company will merge with and into Seagull, with Seagull

         WHEREAS, in anticipation of the Merger, the Company and Executive
desire to amend certain provisions of the Severance Protection Agreement, with
all such amendments to be effective as of the consummation of the Merger;

         NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained in this Amendment, and for
other valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties agree as follows:

         1. Upon the consummation of the Merger, Section 2(b)(3) of the

         2. Upon the consummation of the Merger, the following paragraphs are
added after Section 2(b)(4) and before Section 2(c) of the Severance Protection
Agreement:

                           "(5) Seagull Energy Corporation, as the surviving
                  corporation (the "Surviving Company") of the merger of Ocean
                  Energy, Inc. with and into Seagull Energy Corporation, shall
                  deem Executive "retired" for the purposes of all options
                  granted to the Executive under all stock option plans
                  sponsored by the Company, the Surviving Company or any of
                  their predecessors in order to permit Executive to have the
                  maximum term possible under such plans in which to exercise
                  such options.

                           (6) The Surviving Company shall pay to Executive a
                  cash amount equal to $54,000, which amount represents the
                  total 


<PAGE>   2



                  cost of continuing Executive's current car allowance for
                  thirty-six (36) months plus a $3,600 for gasoline costs.

                           (7) During the term of the Consultancy (as defined
                  below), the Surviving Company shall continue to pay the same
                  club dues for which the Company (or the Surviving Company, as
                  the case may be) is paying on the date of termination of
                  Executive's employment.

                           (8) The Surviving Company shall reimburse Executive
                  in an amount of up to $10,000 for any outplacement costs.

                           (9) The Surviving Company shall reimburse Executive
                  in an amount of up to $20,000 for the cost of any financial or
                  tax consulting.

                           (10) From and after the date of termination of
                  employment upon which benefits become payable under this
                  Section 2(b), the Surviving Company and the Executive agree
                  that the Executive shall be employed by the Surviving Company
                  as a consultant reporting to [Chairman/CEO/President/Board]
                  (the "Consultancy") on a month to month basis for up to twelve
                  (12) months after which the Consultancy shall end. The
                  Consultancy may be earlier terminated by Executive with one
                  month's prior notice at any time during the Consultancy. In
                  consideration for Executive's employment for each month of the
                  Consultancy, Executive shall receive one-twelfth (1/12) of the
                  Base Amount, which shall be payable at the end of each such
                  month (if any). In addition, during the period of the
                  Consultancy, the Surviving Company shall provide the Executive
                  with an allowance for office space, equipment, computers,
                  parking and secretarial assistance of $6,250 per month.

                           (11) Any amount payable under this Section 2(b) shall
                  include an additional amount of cash which will equal any
                  taxes withheld on the portion not deferred such that the net
                  amount of the total payment shall equal the result obtained as
                  if no withholding taxes applied. Should any taxes be due upon
                  the provision of any benefits hereunder (other than taxes due
                  under the operation of Section 4999 of the Code which Section
                  of the Code is addressed in Section 2(d) hereof), the
                  Surviving Company shall pay Executive an amount equal to such
                  taxes (and any taxes thereon) so that Executive incurs no
                  taxes on any benefits received hereunder."

         customary procedures, (C) be for the account of the Company or one of
         its Subsidiaries, and (D) expire not later than the earlier of three
         (3) years after the issue date of such Letter of Credit or five (5)
         days before the Termination Date.

         (iii) In conjunction with the issuance of a Letter of Credit, the
         Company shall execute a Letter of Credit Agreement. In the event of any
         conflict between any provision of a Letter of



                                       18
<PAGE>   25



         Credit Agreement and this Agreement, the Company, the Agents and the
         Lenders hereby agree that the provisions of this Agreement shall
         govern. Such conflicts include, without limitation, provisions in a
         Letter of Credit Agreement providing for an interest rate different
         from the interest rate provided in this Agreement and provisions in a
         Letter of Credit Agreement requiring or relating to collateral to
         secure the obligations thereunder.

         (c) LOANS UNDER PRIOR CREDIT AGREEMENT. On the Effective Date:

         (i) the Company shall pay all accrued and unpaid fees outstanding under
         the Prior Credit Agreement for the account of each "Lender" under the
         Prior Credit Agreement;

         (ii) to the extent outstanding on the Effective Date, each "Base Rate
         Loan" and "Eurodollar Loan" under the Prior Credit Agreement shall be
         repaid and the Company shall pay to the lenders thereunder any amounts
         due under Section 5.05 of the Prior Credit Agreement;

         (iii) all letters of credit issued under the Prior Credit Agreement
         (which are scheduled on Schedule 2.01) shall be deemed to be issued
         under Section 2.02(d) hereof as of the Effective Date; and

         (iv) the Prior Credit Agreement and the commitments thereunder shall be
         superseded by this Agreement and such commitments shall be amended and
         restated as set forth herein.

         SECTION 2.02 BORROWINGS, CONTINUATIONS AND CONVERSIONS; ISSUANCE OF
LETTERS OF CREDIT.

         (a) BORROWINGS. The Company shall give the Administrative Agent (which
shall promptly notify the Lenders) advance notice as hereinafter provided of
each borrowing, continuation, and conversion hereunder of a Loan, which shall
specify the aggregate amount of such borrowing, continuation or conversion, the
Type and date (which shall be a Business Day) of the Loans to be borrowed,
continued or converted, and (in the case of Eurodollar Loans) the duration of
the Interest Period therefor.

         (b) MINIMUM AMOUNTS. All Base Rate Loans (as part of the same
borrowing) shall be in aggregate amounts among all Lenders of at least
$1,000,000 (or whole multiples thereof) or the remaining unused portion of the
Commitments. All Eurodollar Loans (as part of the same borrowing) shall be in
aggregate amounts among all Lenders of at least $3,000,000 (or a whole multiple
of $1,000,000 in excess thereof).

         (c) NOTICES, ETC. FOR LOANS. All borrowings, continuations and
conversions relating to Loans shall require advance written notice from the
Company to the Administrative Agent, in the form of Exhibit C, or such other
form as may be accepted by the Administrative Agent from time to time, which in
each case shall be irrevocable and effective only upon receipt by the
Administrative Agent not later than (i) in the case of a Base Rate Loan, 11:00
a.m. Houston time on the date of such borrowing, continuation or conversion; and
(ii) in the case of a Eurodollar Loan, 12:00 noon Houston time on a day which is
not less than three (3) Business Days prior to the date of such borrowing,
continuation or conversion. Not later than 12:00 noon Houston time on the date
specified for each borrowing hereunder of a Loan, each Lender shall make
available the amount of the Loan to be made by such Lender on such date to the
Administrative Agent, at an account maintained by the Administrative Agent at
the Principal Office, in immediately available funds for the account of the



                                       19
<PAGE>   26




Company. The amounts so received by the Administrative Agent shall, subject to
the terms and conditions of this Agreement, be made available to the Company by
depositing the same, in immediately available funds, in an account of the
Company designated by the Company and maintained with the Administrative Agent
at the Principal Office.

         (d) LETTERS OF CREDIT. The Company shall give the Administrative Agent
(which shall promptly notify the Lenders) advance notice as provided in Section
2.02(c) not less than one (1) Business Day prior thereto of each request for the
issuance, renewal, or extension of a Letter of Credit hereunder which request
shall specify the amount of such Letter of Credit, the date (which shall be a
Business Day) such Letter of Credit is to be issued, renewed or extended, the
duration thereof, the beneficiary thereof, and such other terms as the
Administrative Agent may reasonably request, all of which shall be reasonably
satisfactory to the Administrative Agent. Subject to the terms and conditions of
this Agreement, on the date specified for the issuance, renewal or extension of
a Letter of Credit, the Administrative Agent shall issue such Letter of Credit
to the beneficiary thereof.

         (e) CONTINUATION OPTIONS. Subject to the terms of this Agreement, the
Company may elect to continue all or any part of any Eurodollar Loan beyond the
expiration of the then current Interest Period relating thereto by giving
advance notice to the Administrative Agent of such election, specifying the
amount of such Eurodollar Loan to be continued and the Interest Period therefor.
In the absence of such a timely and proper election, the Company shall be deemed
to have elected to convert such Eurodollar Loan to a Base Rate Loan. All or any
part of any Eurodollar Loan may be continued as provided herein, provided that
(i) the principal amount of all or any part of a Loan so continued shall be not
less than $3,000,000 in the aggregate for all Lenders and (ii) no Default shall
have occurred and be continuing. If a Default shall have occurred and be
continuing, each Eurodollar Loan shall be converted to a Base Rate Loan on the
last day of the Interest Period applicable thereto.

         (f) CONVERSION OPTIONS. The Company may elect to convert any Eurodollar
Loan on the last day of the then current Interest Period relating thereto to a
Base Rate Loan by giving advance notice to the Administrative Agent of such
election. Subject to the terms of this Agreement, the Company may elect to
convert all or any part of a Base Rate Loan at any time and from time to time to
a Eurodollar Loan by giving advance notice to the Administrative Agent of such
election. All or any part of any outstanding Loan may be converted as provided
herein, provided that any conversion of any Base Rate Loan into a Eurodollar
Loan shall be (as to each such Loan into which there is a conversion for an
applicable Interest Period) in the principal amount not less than $3,000,000 in
the aggregate for all Lenders. If no Default shall have occurred and be
continuing, each Loan may be converted as provided in this Section. If a Default
shall have occurred and be continuing, no Loan may be converted into a
Eurodollar Loan.

         SECTION 2.03 EXTENSIONS AND CHANGES OF COMMITMENTS.

         (a) EXTENSION OF TERMINATION DATE.

                  (i) At any time during the 60-day period beginning February
1st of a year and ending on April 1st of such year, the Company may request in
writing that, in connection with the forthcoming redetermination of the
Borrowing Base, the Lenders extend the Termination Date for a period of one (1)
additional year; provided, that any such extension shall require the consent of
all of the Lenders, which consent may be withheld in each such Person's sole
discretion; and provided, further, that if any



                                       20
<PAGE>   27




Lender has not responded to such request in writing within 45 days after receipt
of the written request of the Company by the Administrative Agent, such failure
shall be deemed a denial of said request.

                  (ii) Notwithstanding the foregoing clause (i), if the Required
Lenders (but not all Lenders) have agreed to extend the then applicable
Termination Date as provided in Section 2.03(a)(i), then the Company may
terminate, in whole but not in part, the Commitment of any Lender which has
refused to grant such extension (a "Terminated Lender") upon five (5) Business
Days' notice, during the period commencing on the expiration of the 45-day
notice period referred to above (or, if earlier, the date of receipt by the
Company of notice of such Terminated Lender's refusal) and ending on the date
thirty (30) days after the end of such 45-day period, by giving written notice
to the Terminated Lender and the Administrative Agent (such notice referred to
herein as a "Notice of Termination"). In order to effect the termination of the
Commitment of the Terminated Lender, the Company shall: (1) obtain an agreement
with one or more Lenders to increase its respective Commitment and/or (2)
request any one or more other financial institutions to become parties to this
Agreement in place of such Terminated Lender; provided, that any such financial
institution is reasonably acceptable to the Administrative Agent and becomes
party to this Agreement by executing an Assignment and Acceptance (the Lender or
other financial institutions that agree to accept in whole or in part the
Commitment of the Terminated Lender being referred to herein as the "Replacement
Lender") and to assume the Commitment and Loans of the Terminated Lender, such
that the aggregate increased and/or accepted Commitments of the Replacement
Lender(s) under clauses (1) and (2) equal the Commitment of the Terminated
Lender. If the Company is unable to obtain one or more Replacement Lenders to
accept the Commitment and to assume the Loans of the Terminated Lender, then, if
no Default or Event of Default has occurred at the time of such proposed
extension, the Company shall either elect by written notice to the
Administrative Agent to forego the requested extension or reduce the Aggregate
Commitments by an amount equal to the Commitment of the Terminated Lender. (The
failure to give such notice will be deemed an election by the Company to forego
the requested extension.) If a Default or Event of Default has occurred and is
continuing, no extension will be permitted without the consent of all Lenders.
Any assignment to a Replacement Lender shall be effected pursuant to Section
12.06(b).

         (b) OPTIONAL REDUCTION. The Company shall have the right to terminate
or to reduce the Aggregate Commitments at any time or from time to time upon not
less than one (1) Business Day's prior written notice to the Administrative
Agent (which shall promptly notify the Lenders) of each such termination or
reduction, which notice shall specify the effective date thereof and the amount
of any such reduction (which shall not be less than $5,000,000, or any whole
multiple of $1,000,000 in excess thereof). Such notice shall be irrevocable and
effective only upon receipt by the Administrative Agent.

         (c) REINSTATEMENT. The Aggregate Commitments once terminated or reduced
may not be reinstated. The amount of the Available Commitment may increase or
decrease from time to time in accordance with the terms hereof, including, but
not limited to Section 2.09.

         SECTION 2.04 FACILITY FEE AND OTHER FEES.

         (a) FACILITY FEE. The Company shall pay to the Administrative Agent for
the account of the Lenders a facility fee (the "Facility Fee") in an aggregate
amount equal to the Facility Fee Rate times an amount equal to the average daily
Available Commitment. The Facility Fee will accrue for the period from and
including the Effective Date to and including the Termination Date, without
regard



                                       21
<PAGE>   28


to the outstanding principal amount of Loans outstanding. Accrued Facility Fees
shall be payable in arrears on each Quarterly Date and on the Termination Date.

         (b) LETTER OF CREDIT FEE. The Company agrees to pay to the
Administrative Agent for the account of the Lenders a quarterly fee for issuing
the Letters of Credit, calculated separately for each Letter of Credit, in an
aggregate amount for each Letter of Credit equal to 1/4 of the product of (i)
the LC Fee Rate, as then in effect, and (ii) the daily average balance during
such quarter of the amount of the Letter of Credit upon which drafts may be
drawn from time to time commencing on the date of issuance of such Letter of
Credit (or on the Effective Date for Letters of Credit issued under the Prior
Credit Agreement and outstanding on the Effective Date); provided that each
respective Letter of Credit shall bear an aggregate minimum quarterly fee equal
to $350, or such other fee as may be specifically agreed by the Company and the
Administrative Agent in each respective Letter of Credit Agreement. All fees for
all Letters of Credit (including all fees incurred for any amendments to Letters
of Credit) shall be payable in arrears on each Quarterly Date.

         (c) ISSUING FEE. In addition to the fees described in Section 2.04(b),
the Company shall pay to the Administrative Agent for its own account a
quarterly fee for issuing each Letter of Credit, calculated separately for each
Letter of Credit, in an aggregate amount for each Letter of Credit equal to 1/4
of the product of (i) .125% per annum and (ii) the daily average balance during
such quarter of the amount of the Letter of Credit upon which drafts may be
drawn from time to time commencing on the date of issuance of such Letter of
Credit (or on the Effective Date for Letters of Credit issued under the Prior
Credit Agreement and outstanding on the Effective Date). All fees for all
Letters of Credit (including all fees incurred for any amendments to Letters of
Credit) shall be payable in arrears on each Quarterly Date.

         (d) FEE LETTERS. The Company shall pay to the Administrative Agent and
its Affiliates and the Lenders such other amounts as are set forth in the Fee
Letters on the dates set forth therein.

         SECTION 2.05 LENDING OFFICES. The Loans of each Type made by each
Lender shall be made and maintained at such Lender's Applicable Lending Office
for Loans of such Type.

         SECTION 2.06 SEVERAL OBLIGATIONS. The failure of any Lender to make any
Loan to be made by such Lender or to provide funds for disbursements under
Letters of Credit on the date specified therefor shall not relieve any other
Lender of its obligation to make its Loan or provide such funds on such date,
but no Lender shall be responsible for the failure of any other Lender to make a
Loan to be made by such other Lender or to provide funds to be provided by such
other Lender.

         SECTION 2.07 NOTES.

         (a) NOTES. The Loans made by each Lender shall be evidenced by a single
promissory note of the Company in substantially the form of Exhibit A, dated as
of the Effective Date or such later date that a Lender becomes a party hereto,
payable to the order of such Lender in a principal amount equal to the maximum
amount of its Commitment as originally in effect and otherwise duly completed.
The date, amount, Type and interest rate of each Loan made by each Lender, and
all payments made on account of the principal thereof, shall be recorded by such
Lender on its books and, prior to any transfer of the Note held by it, endorsed
by such Lender on the schedule attached to such Note or any continuation
thereof; provided that the failure of a Lender to make any notation shall not
affect the Company's obligations in respect of such Loan.



                                       22
<PAGE>   29


         (b) NO RIGHT TO SUBDIVIDE. No Lender shall be entitled to have its
Notes subdivided, by exchange for promissory notes of lesser denominations or
otherwise, except in connection with a permitted assignment of all or any
portion of such Lender's Commitment, Loans and Notes pursuant to Section
12.06(b).

         SECTION 2.08 PREPAYMENTS.

         (a) OPTIONAL PREPAYMENTS. The Company may prepay Loans on any Business
Day upon notice to the Administrative Agent (which shall promptly notify the
Lenders), which notice (i) shall be given by the Company not later than 12:00
noon Houston time on such Business Day, (ii) shall specify the amount of the
prepayment (which shall be not less than $1,000,000 or the remaining balance of
Base Rate Loans outstanding, if less) and (iii) shall be irrevocable and
effective only upon receipt by the Administrative Agent. Interest on the
principal prepaid, accrued to the prepayment date, shall be paid on the
prepayment date. Any prepayment of any Eurodollar Loans shall be subject to the
provisions of Section 5.05.

         (b) MANDATORY PREPAYMENT UPON REDUCTION OF COMMITMENT. If, after giving
effect to any termination or reduction of the Aggregate Commitments pursuant to
Section 2.03, the sum of the outstanding aggregate principal amount of the Loans
and the LC Exposure exceeds the Aggregate Commitments, then the Company shall on
the date of such termination or reduction pay or prepay the amount of such
excess for application first, towards reduction of all amounts previously drawn
under Letters of Credit, but not yet funded as a Loan pursuant to Section
4.07(b) or reimbursed, second, if necessary, towards reduction of the
outstanding principal balance of the Notes by prepaying Base Rate Loans, if any,
then outstanding, third, if necessary, toward a reduction of the outstanding
principal balance of the Notes by prepaying Eurodollar Loans, if any, then
outstanding, and fourth, if necessary, paying such amount to the Administrative
Agent as cash collateral for outstanding Letters of Credit, which amount shall
be held by the Administrative Agent as cash collateral to secure the Company's
obligation to reimburse the Administrative Agent and the Lenders for drawings
under the Letters of Credit. The Company shall on the date of such termination
or reduction also pay any amounts payable pursuant to Section 5.05 in connection
therewith.

         (c) MANDATORY PREPAYMENT UPON REDETERMINATION. Upon any adjustment or
redetermination of the amount of the Borrowing Base in accordance with (1)
Section 2.09, (2) Section 8.05(d), (3) Section 9.01(e), (4) Section 9.01(o), (5)
Section 9.16(b) or (6) Section 9.21 or otherwise, if the adjusted or
redetermined Borrowing Base is less than the sum of the aggregate outstanding
principal amount of the Loans, the LC Exposure and all Pari Passu Debt then
outstanding (a "Borrowing Base Deficiency"), then the Company shall within 90
days of receipt of written notice thereof either (i) take such steps as may be
approved by the Administrative Agent to increase the Borrowing Base by an amount
equal to or greater than the amount of such Borrowing Base Deficiency or (ii)
prepay the amount of such Borrowing Base Deficiency for application first,
towards reduction of all amounts previously drawn under Letters of Credit, but
not yet funded as a Loan pursuant to Section 4.07(b) or reimbursed, second, if
necessary, towards reduction of the outstanding principal balance of the Notes
by prepaying Base Rate Loans, if any, then outstanding, third, if necessary,
towards a reduction of the outstanding principal balance of the Notes by
prepayment of Eurodollar Loans, if any, then outstanding, and fourth, if
necessary, towards payment of such amount to the Administrative Agent as cash
collateral for outstanding Letters of Credit, which amount shall be held by the
Administrative Agent as cash collateral to secure the Company's obligation to
reimburse the Administrative Agent and the Lenders for drawings under the
Letters of Credit; provided however that



                                       23
<PAGE>   30




if a Borrowing Base Deficiency occurs during the period from and after the
Effective Date up to and including the redetermination to occur as of March 31,
1999, such Borrowing Base Deficiency must be repaid within 30 days. The Company
shall also pay any amounts payable pursuant to Section 5.05 in connection
therewith.

         (d) MANDATORY PAYMENTS UPON ISSUANCE OF EQUITY. If the Company shall
issue any shares of capital stock, on or prior to March 31, 1999, then on the
date not less than 30 days after such issuance, the Company shall make a payment
on the Loans and/or post cash collateral for Letters of Credit by an amount
equal to the lesser of (i) the net cash proceeds of such issuance or (ii) the
excess of the sum of the Loans then outstanding, the LC Exposure and the Pari
Passu Debt over the Threshold Amount; provided that the foregoing requirement
will be waived following a written certification from the Company setting forth
that such net cash proceeds have been or are being contemporaneously utilized by
it or one of its Restricted Subsidiaries to purchase Oil and Gas Properties
which are substantially all proved producing.

         (e) NO PENALTY OR PREMIUMS. Subject to compensation requirements of
Section 5.05, all prepayments shall be without premium or penalty.

         SECTION 2.09 BORROWING BASE.

         (a) (i) The initial Borrowing Base shall be $650,000,000 and the
         initial Threshold Amount shall be $550,000,000. From and after the
         redetermination of the Borrowing Base scheduled to occur on March 31,
         1999, the Borrowing Base, as redetermined, shall be equal to the
         Threshold Amount and thereafter, the rights and obligations of the
         parties hereunder shall be determined with reference to the Borrowing
         Base only.

         (ii) Subject to the terms of Section 2.09(a)(i), the Borrowing Base
         shall be determined in accordance with Sections 2.09(b), (c) and (d) by
         the Technical Agents with the approval or deemed approval of the
         Required Lenders (provided that any increase in the Borrowing Base
         shall require the approval or deemed approval of all the Lenders).
         Subject to the rights of the parties under Section 2.09(e), the
         Borrowing Base will initially be redetermined as of March 31, 1999 in
         accordance with Section 2.09(b), and thereafter, the Borrowing Base
         will be redetermined semi-annually on May 1st and November 1st of each
         year in accordance with Section 2.09(b), commencing November 1, 1999.
         Upon any redetermination of the Borrowing Base, such redetermination
         shall remain in effect until the next successive Redetermination Date.

         (iii) Notwithstanding the fact that the Borrowing Base exceeds or may
         from time to time exceed the Aggregate Commitments, the obligations of
         the Lenders hereunder is limited as contemplated in the definition of
         "Available Commitment."

         (b) REDETERMINATION. On or before March 15, 1999, and thereafter, on or
before April 1st and October 1st of each year, commencing October 1, 1999, the
Technical Agents shall propose in writing to the Company and the Lenders a new
Borrowing Base in accordance with Section 2.09(c) (assuming receipt by the
Technical Agents of the Engineering Reports in a timely and complete manner).
After having received notice of such proposal by the Technical Agents, each
Lender shall have ten (10) days to agree with such proposal or disagree by
proposing an alternate Borrowing Base. If at the end of ten (10) days, any
Lender has not communicated its approval or disapproval, such


                                                        

                                       24
<PAGE>   31


silence shall be deemed to be an approval. If, however, at the end of such
10-day period, all of the Lenders in the case of the redetermination scheduled
for March 31, 1999, and thereafter, the Required Lenders, have not approved or
deemed to have approved, as aforesaid, the proposed Borrowing Base, then the
Borrowing Base shall be determined in accordance with Section 2.09(d). After
such redetermined Borrowing Base is approved by the requisite Lenders or is
otherwise determined as provided in Section 2.09(d), it shall become effective
and applicable to the Company, the Agents, the Lenders as of March 31, 1999 (in
the case of the March 1999 redetermination only) or the next succeeding May 1st
or November 1st, as applicable.

         (c) ENGINEERING REPORTS. Upon receipt of the Reserve Reports and such
other reports, data, and supplemental information as may, from time to time, be
reasonably requested by the Required Lenders (the "Engineering Reports"),
together with a certificate from the President or chief financial officer of the
Company that, to the best of his knowledge and in all material respects, (i) the
information contained in the Engineering Reports is true and correct, (ii) the
certificate identifies the Properties covered by the Engineering Reports that
have not been previously included in any prior Engineering Reports, and (iii) no
other Oil and Gas Properties have been sold since the date of the last Borrowing
Base determination except as set forth on an exhibit to the certificate, which
certificate shall list all Oil and Gas Properties sold or disposed of in
compliance with Section 9.16 (or pursuant to a waiver thereof) and in such
detail as reasonably required by the Technical Agents, the Technical Agents will
evaluate such information. The Technical Agents, with the approval or deemed
approval of the requisite Lenders as set forth in Section 2.09(b), but subject
to the terms of Section 2.09(d), shall redetermine the Borrowing Base based upon
such information and such other information (including, without limitation, the
Indebtedness) as the Technical Agents deem appropriate and consistent with their
normal oil and gas lending criteria as it exists at the particular time
(including, without limitation, the status of title information with respect to
Properties in the Engineering Reports and the existence of any other Debt). Such
redetermination shall be accomplished not later than and effective as of March
31, 1999, in the case of the initial redetermination, and thereafter as of the
first (1st) day of each May and November of each calendar year, assuming that
the Company shall have furnished the Engineering Reports in a timely and
complete manner.

         (d) CONSENSUS AND FAILURE OF CONSENSUS. Except as otherwise provided in
this Section 2.09, the decision of the Required Lenders with respect to any
Borrowing Base determination shall control; however, if the Required Lenders
have not approved or are not deemed to have approved the Borrowing Base as of
the date such a determination is called for in Section 2.09(b), the Technical
Agents shall poll the Lenders to ascertain the highest Borrowing Base then
acceptable to a number of Lenders sufficient to constitute the Required Lenders
for purposes of this Section 2.09 and such amounts shall then become the
Borrowing Base for the next Redetermination Period. Notwithstanding the
foregoing, however, (i) approval of the Borrowing Base determined any time after
the Effective Date to and including the Borrowing Base determined as of March
31, 1999, and (ii) thereafter any increase in the Borrowing Base, shall require
the consent of all the Lenders.

         (e) INTERIM REDETERMINATIONS. The Company may, at its option one time
during a 12 month period, initiate an interim redetermination of the Borrowing
Base and the Threshold Amount. The Administrative Agent (at the direction of the
Required Lenders, in their option) may, one time during any 12 month period,
initiate an interim redetermination of the Borrowing Base; provided however that
the Agents and the Lenders hereby waive their right to do so prior to the
redetermination under Section 2.09(b) occurring on or before March 31, 1999.




                                       25
<PAGE>   32



         (f) OTHER ADJUSTMENTS. The Borrowing Base is also subject to adjustment
as set forth in Sections 8.05(d), 9.01(e)(iii), 9.01(o), 9.16(b) and 9.21. If
during any Redetermination Period prior to and including the date of the
redetermination of the Borrowing Base scheduled to occur March 31, 1999, the
Borrowing Base is adjusted pursuant to any of the foregoing sections, then the
Threshold Amount shall also automatically reduce by an amount equal to the
Threshold Amount prior to such adjustment times a fraction the numerator of
which is the amount of the Borrowing Base outstanding after giving effect to
such adjustment and the denominator of which is the Borrowing Base outstanding
prior to giving effect to such adjustment.

                                   ARTICLE III
                       PAYMENTS OF PRINCIPAL AND INTEREST

         SECTION 3.01 REPAYMENT OF LOANS. The Company will pay on the
Termination Date to the Administrative Agent for the account of each Lender the
then-outstanding principal amount of each Loan made by such Lender.

         SECTION 3.02 INTEREST.

         (a) The Company will pay to the Administrative Agent for the account of
each Lender interest on the unpaid principal amount of each Loan made by such
Lender for the period commencing on the date of such Loan to but excluding the
date such Loan shall be paid in full, at the following rates per annum:

         (i) if such Loan is a Base Rate Loan, the Base Rate (as in effect from
         time to time) plus the Applicable Margin for Base Rate Loans, but in no
         event to exceed the Highest Lawful Rate; and

         (ii) if such Loan is a Eurodollar Loan, for each Interest Period
         relating thereto, the Eurodollar Rate for such Loan plus the Applicable
         Margin for Eurodollar Loans, but in no event to exceed the Highest
         Lawful Rate.

         Notwithstanding the foregoing, the Company will pay to the
Administrative Agent for the account of each Lender interest at the applicable
Post-Default Rate on any principal of any Loan made by such Lender, and, to the
fullest extent permitted by law, on any other amount payable by the Company or
OEI-Louisiana hereunder or under any Loan Document, that shall not be paid in
full when due (whether at stated maturity, by acceleration or otherwise), for
the period commencing on the due date thereof until the same is paid in full,
but in no event to exceed the Highest Lawful Rate.

         (b) Accrued interest on each Base Rate Loan shall be payable quarterly
on each Quarterly Date. Accrued interest on each Eurodollar Loan shall be
payable on the last day of the Interest Period therefor and, if such Interest
Period is longer than three months or ninety (90) days, at three-month or ninety
(90) day intervals, as appropriate, following the first day of such Interest
Period. In any event, interest payable at the Post-Default Rate shall be payable
from time to time on demand and interest on any Eurodollar Loan that is
converted into a Base Rate Loan pursuant to Section 5.04 shall be payable on the
date of conversion (but only to the extent so converted).

         (c) Promptly after the determination of any interest rate provided for
herein or any change therein, the Administrative Agent shall notify the Company
and the Lenders to which such interest is



                                       26
<PAGE>   33




payable thereof. Upon notice to the Administrative Agent of the incurrence of
Debt pursuant to Section 8.01(g), the incurrence of any Pari Passu Debt or
Subordinated Debt and/or any change in the amount of the Indebtedness (including
the LC Exposure) outstanding hereunder, the Administrative Agent shall promptly
determine the Percentage Usage and, in the event such circumstances result in a
change in the Applicable Margin, the Facility Fee Rate and the LC Fee Rate, the
Administrative Agent shall notify the Lenders and the Company. Such new
Applicable Margin, the Facility Fee Rate and the LC Fee Rate will be applicable
until the next day on which events described in this Section 3.02(c) result in a
change and notice thereof is given by the Administrative Agent.

                                   ARTICLE IV
                PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

         SECTION 4.01 PAYMENTS. Except to the extent otherwise provided herein,
all payments of principal, interest and other amounts to be made by the Company
under this Agreement, the Notes and other Loan Documents shall be made in
Dollars, in immediately available funds, to the Administrative Agent at an
account maintained by the Administrative Agent at the Principal Office, not
later than 1:00 p.m. Houston time on the date on which such payments shall
become due (each such payment made after such time on such due date to be deemed
to have been made on the next succeeding Business Day). The Company shall,
subject to Section 4.02, at the time of making each payment under this
Agreement, any Note or any other Loan Document, specify to the Administrative
Agent the Loans, Letters of Credit or other amounts payable by the Company
hereunder to which such payment is to be applied (and in the event that it fails
to so specify, and such day is not a Quarterly Date or other day on which a
payment of either interest or principal is due, then such payments shall be
applied in the following order: first, to interest accrued on Loans maintained
as Base Rate Loans, second, any excess to reduce the aggregate principal amount
then outstanding on Loans maintained as Base Rate Loans, third, any excess to
interest accrued on Loans maintained as Eurodollar Loans, and fourth any excess
to reduce the aggregate principal amount then outstanding on Loans maintained as
Eurodollar Loans; provided that if an Event of Default has occurred and is
continuing, the Administrative Agent may distribute such payment to the Lenders
in such manner as it or the Majority Lenders may determine to be appropriate,
subject to Section 4.02). Each payment received by the Administrative Agent
under this Agreement, any Note or any other Loan Document for the account of a
Lender shall be paid promptly to such Lender, in immediately available funds,
for account of such Lender's Applicable Lending Office for the Loan, Letter of
Credit or other amount in respect of which such payment is made. Except as
provided in clause (ii) of the provisions of the definition of Interest Period,
if the due date of any payment under this Agreement, any Note or any other Loan
Document would otherwise fall on a day which is not a Business Day such date
shall be extended to the next succeeding Business Day and interest shall be
payable for any principal so extended for the period of such extension.

         SECTION 4.02 PRO RATA TREATMENT. Except as set forth in Sections
2.03(a)(ii) or Section 5.07(b) or to the extent otherwise provided herein: (a)
(i) each borrowing from the Lenders under Section 2.01 shall be made from the
Lenders in such amounts as may be necessary so that, after giving effect to such
borrowing, the outstanding Loans shall have been made pro rata by the Lenders
based on their respective Commitment Percentages as then in effect, (ii) each
payment of Facility Fee or other fees under Sections 2.04(a) and (b) shall be
made for the account of the Lenders pro rata according to their respective
Commitment Percentages, and (iii) each termination or reduction of the amount of
the Commitments under Section 2.03 shall be applied to the Commitments of the
Lenders pro rata according to their respective Commitment Percentage; (b) each
payment of principal of Loans by the Company shall be made for the account of
the Lenders pro rata in accordance with the



                                       27
<PAGE>   34




respective unpaid principal amount of the Loans held by the Lenders; (c) each
payment of interest on Loans by the Company shall be made for the account of the
Lenders pro rata in accordance with the amounts of interest due and payable on
such Loans to the respective Lenders; and (d) each reimbursement by the Company
of disbursements under Letters of Credit shall be made for the account of the
Lenders pro rata in accordance with the amounts of reimbursement obligations due
and payable on such Letters of Credit to the respective Lenders.

         SECTION 4.03 COMPUTATIONS. Interest on Eurodollar Loans shall be
computed on the basis of a year of 360 days and actual days elapsed (including
the first day but excluding the last day) occurring in the period for which such
interest is payable (unless such calculation would result in a rate of interest
that would exceed the Highest Lawful Rate for any Lender in which event such
calculation for such Lender shall be computed on the basis of a year of 365 or
366 days, as the case may be). Interest on Base Rate Loans and fees shall be
computed on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed (including the first day but excluding the last day)
occurring in the period for which payable.

         SECTION 4.04 NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT. Unless
the Administrative Agent shall have been notified by a Lender or the Company
prior to the date on which a payment is scheduled to be made to the
Administrative Agent of (in the case of a Lender) the proceeds of a Loan to be
made by it hereunder or under a Letter of Credit or (in the case of the Company)
a payment to the Administrative Agent for account of one or more of the Lenders
hereunder (such payment being herein called a "Required Payment"), which notice
shall be effective upon receipt, that it does not intend to make the Required
Payment to the Administrative Agent, the Administrative Agent may assume that
the Required Payment has been made and may, in reliance upon such assumption
(but shall not be required to), make the amount thereof available to the
intended recipient(s) on such date. If such Lender or the Company (as the case
may be) has not in fact made the Required Payment to the Administrative Agent,
the recipient(s) of such payment shall, on demand, repay to the Administrative
Agent the amount so made available together with interest thereon in respect of
each day during the period commencing on the date such amount was so made
available by the Administrative Agent until the date the Administrative Agent
recovers such amount at a rate per annum equal to the Base Rate for such day,
but in no event to exceed the Highest Lawful Rate.

         SECTION 4.05 SHARING OF PAYMENTS, ETC.

         (a) The Company agrees that, in addition to (and without limitation of)
any right of set-off, bankers' lien or counterclaim a Lender may otherwise have,
each Lender shall be entitled (after consultation with the Administrative
Agent), at its option, during the existence of an Event of Default, to offset
balances held by it for account of the Company at any of its offices, in Dollars
or in any other currency, against any principal of or interest on any of such
Lender's Loans or any other amount payable to such Lender hereunder or under any
other Loan Document which is not paid when due (regardless of whether such
balances are then due to the Company), in which case such Lender shall promptly
notify the Company and the Administrative Agent thereof, provided that such
Lender's failure to give such notice shall not affect the validity thereof.

         (b) If any Lender shall obtain payment of any principal of or interest
on any Loan made by it to the Company under this Agreement or payment of any
reimbursement obligation under a Letter of Credit Agreement through the exercise
of any right of set-off, banker's lien or counterclaim or similar right or
otherwise, and, as a result of such payment, such Lender shall have received a
greater



                                       28
<PAGE>   35




percentage of the principal or interest or reimbursement obligation then due
hereunder or under the respective Letter of Credit Agreement, as the case may
be, by the Company to such Lender than the percentage received by any other
Lenders, such Lender shall promptly purchase from such other Lenders
participations in (or, if and to the extent specified by such Lender, direct
interests in) the Loans made by such other Lenders (or in interest due thereon,
as the case may be) or reimbursement obligations under the Letter of Credit
Agreements in such amounts, and make such other adjustments from time to time as
shall be equitable, to the end that all the Lenders shall share the benefit of
such excess payment (net of any expenses which may be incurred by such Lender in
obtaining or preserving such excess payment) pro rata in accordance with the
unpaid principal and/or interest on the Loans held by each of the Lenders or pro
rata in accordance with the unpaid reimbursement obligation owed to each of the
Lenders. To such end, all the Lenders shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such payment
is rescinded or must otherwise be restored. The Company agrees that any Lender
so purchasing a participation (or direct interest) in the Loans made by other
Lenders (or in interest due thereon, as the case may be) or in the reimbursement
obligations owed to the other Lenders may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender were a direct holder of Loans or reimbursement
obligations, as the case may be, in the amount of such participation. Nothing
contained herein shall require any Lender to exercise any such right or shall
affect the right of any Lender to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or obligation
of the Company. If under any applicable bankruptcy, insolvency or other similar
law, any Lender receives a secured claim in lieu of a set-off to which this
Section 4.05 applies, such Lender shall, to the extent practicable, exercise its
rights in respect of such secured claim in a manner consistent with the rights
of the Lenders entitled under this Section 4.05 to share the benefits of any
recovery on such secured claim.

         SECTION 4.06 ASSUMPTION OF RISKS. The Company assumes all risks of the
acts or omissions of beneficiaries of any of the Letters of Credit with respect
to its use of the Letters of Credit. Except in the case of gross negligence or
willful misconduct on the part of such Person or any of its employees, neither
the Administrative Agent, the Administrative Agent's correspondents, any other
Agent, nor any Lender shall be responsible: (a) for the validity or genuineness
of certificates or other documents, even if such certificates or other documents
should in fact prove to be invalid, fraudulent or forged; (b) for errors,
omissions, interruptions or delays in transmissions or delivery of any messages
by mail, telex, or otherwise, whether or not they be in code; (c) for errors in
translation or for errors in interpretation of technical terms; or (d) for any
other consequences arising from causes beyond the Administrative Agent's
control. In addition, neither the Administrative Agent, any other Agent nor any
Lender shall be responsible for any error, neglect, or default of any of the
Administrative Agent's correspondents which were chosen in good faith; and none
of the above shall affect, impair or prevent the vesting of any of the
Administrative Agent's rights or any Lender's rights or powers hereunder or
under the Letter of Credit Agreements, all of which rights shall be cumulative.
The Administrative Agent and the Administrative Agent's correspondents may
accept certificates or other documents that appear on their face to be in order,
without responsibility for further investigation. In furtherance and not in
limitation of the foregoing provisions, the Company agrees that any action,
inaction or omission taken or not taken by the Administrative Agent or any
correspondent in the absence of gross negligence or willful misconduct by the
Administrative Agent or any correspondent in connection with any Letter of
Credit, or any related drafts, certificates, documents or instruments, shall be
binding on the Company and shall not put the Administrative Agent or its
correspondents or any Lender under any resulting liability to the Company.

         SECTION 4.07 OBLIGATION TO REIMBURSE AND TO PREPAY.

         (a) If any draft or claim shall be presented for payment under a Letter
of Credit, after confirming that such draft or claim complies with all
requirements of the relevant Letter of Credit, the Administrative Agent shall
promptly notify the Company and each Lender orally (confirming such notice
promptly in writing) of the date and the amount of the draft or claim presented
for payment, the Business Day on which such draft or claim is to be honored and,
in the case of each Lender, the ratable share of such draft or claim
attributable to such Lender on the basis of its Commitment Percentage then in
effect.

         (b) If a disbursement by the Administrative Agent is made under any
Letter of Credit and no Default under this Agreement shall have occurred and be
continuing, the Company may elect, and if no election is made, the Company shall
be deemed to have elected, to have the amount of such disbursement treated as a
Loan to the Company as provided, and subject to the limitations, in Section
2.01(a), subject to the terms and conditions set forth in this Agreement. With
respect to any disbursement under a Letter of Credit after and during the
continuance of a Default, the amount of such disbursement shall be due and
payable immediately and the Company shall pay to the Administrative Agent,
promptly after notice of such disbursement is received by the Company, in
federal or other immediately available funds, the amount of such disbursement,
together with interest on the amount disbursed from and including the date of
disbursement until payment in full of such disbursed amount at a varying rate
per annum equal to (i) the Base Rate (as in effect from time to time) plus the
Applicable Margin for Base Rate Loans (but in no event to exceed the Highest
Lawful Rate) for the first Business Day following the date of such disbursement
and (ii) the Post-Default Rate for Base Rate Loans for the period from and
including the second Business Day following the date of such disbursement to and
including the date of repayment in full of such disbursed amount.

         (c) The Company's obligation to make each such payment shall be
absolute and unconditional and shall not be subject to any defense or be
affected by any right of setoff, counterclaim or recoupment which the Company
may now or hereafter have against any beneficiary of any Letter of Credit, the
Administrative Agent, any other Agent, any Lender or any other Person for any
reason whatsoever (but, without prejudice to any other provisions hereof, any
such payment shall not waive, impair or otherwise adversely affect any claim, if
any, that the Company may have against any beneficiary of a Letter of Credit,
the Administrative Agent, any other Agent, any Lender or any other Person).

         (d) If an Event of Default shall have occurred and be continuing, the
Company shall, upon request of the Majority Lenders, pay to the Administrative
Agent as cash collateral an amount equal to the LC Exposure. The Company's
obligation to provide such cash collateral shall be absolute and unconditional
without regard to whether any beneficiary of any such Letter of Credit has
attempted to draw down all or a portion of such amount under the terms of a
Letter of Credit. In addition, the Company's obligation shall not be subject to
any defense or be affected by a right of setoff, counterclaim or recoupment
which the Company may now or hereafter have against any such beneficiary, any
Agent, any Lender or any other Person for any reason whatsoever (but, without
prejudice to any other provisions hereof, any such payment shall not waive,
impair or otherwise adversely affect any claim, if any, that the Company may
have against any beneficiary of a Letter of Credit, the Administrative Agent,
any other Agent, any Lender or any other Person). The Company hereby grants to
the Administrative Agent, for the benefit of the Agents and the Lenders, a
security interest in all such cash to secure the LC Exposure and any and all
other Indebtedness now or hereafter



                                       30
<PAGE>   37




owing hereunder. If the Company shall provide cash collateral under this Section
4.07 or shall prepay any Letter of Credit pursuant to Section 2.08 and
thereafter either (i) drafts or other demands for payment complying with the
terms of such Letters of Credit are not made prior to the respective expiration
dates thereof, or (ii) such Event of Default shall have been waived or cured,
then the Agents and the Lenders agree that the Administrative Agent is hereby
authorized, without further action by any other Agent or Lender, to release the
Lien in such cash and will direct the Administrative Agent to remit to the
Company amounts for which the contingent obligations evidenced by such Letters
of Credit have ceased.

         SECTION 4.08 OBLIGATIONS FOR LETTERS OF CREDIT.

         (a) Immediately, (i) upon issuance of any Letter of Credit by the
Administrative Agent and (ii) effective on the Effective Date with respect to
Letters of Credit outstanding under the Prior Credit Agreement on the Effective
Date, each Lender shall be deemed to be a participant through the Administrative
Agent in the obligation of the Administrative Agent under such Letter of Credit.
Upon the delivery by such Lender to the Administrative Agent of funds requested
for a disbursement pursuant to Section 4.08(c), such Lender shall be deemed as
having purchased a participating interest in the Company's reimbursement
obligations with respect to such Letter of Credit in an amount equal to such
funds delivered to the Administrative Agent.

         (b) Each Lender severally agrees with the Administrative Agent and the
Company that it shall be unconditionally liable to the Administrative Agent,
without regard to the occurrence of any Default or Event of Default, for its pro
rata share, based upon its Commitment Percentage, of disbursements under any
Letter of Credit, and agrees to reimburse on demand the Administrative Agent for
its pro rata share of each such disbursement.

         (c) The Administrative Agent shall promptly request from each Lender
its ratable share of any disbursement under any Letter of Credit that the
Company has not elected hereunder to treat as a Loan pursuant to Section 4.07,
which amount shall be made available by each Lender to the Administrative Agent
at the Principal Office in immediately available funds no later than 2:00 p.m.
Houston time on the date requested. If such amount due to the Administrative
Agent is made available later than 2:00 p.m. Houston time on the date requested,
then such Lender shall pay to the Administrative Agent such amount with interest
thereon in respect of each day during the period commencing on the date such
amount was requested until the date the Administrative Agent receives such
amount at a rate per annum equal to the Base Rate (but not to exceed the Highest
Lawful Rate).

                                    ARTICLE V
                         YIELD PROTECTION AND ILLEGALITY

         SECTION 5.01 ADDITIONAL COSTS.

         (a) EURODOLLAR REGULATIONS. The Company shall pay directly to each
Lender such amounts as such Lender may determine to be necessary to compensate
it for any increased costs incurred by the Lender which such Lender determines
are attributable to its making or maintaining any Eurodollar Loans or its
obligation to make any Eurodollar Loans hereunder, or any reduction in any
amount receivable by such Lender hereunder in respect of any of such Loans or
such obligation (such increases in costs and reductions in amounts receivable
being herein called "Additional Costs"), resulting from any Regulatory Change
which: (i) changes the basis of taxation of any amounts payable



                                       31
<PAGE>   38




to such Lender under this Agreement or its Notes in respect of any of such Loans
(other than franchise taxes, taxes on capital and/or gross receipts or taxes
imposed on the overall net income of such Lender or of its Applicable Lending
Office for any of such Loans by the jurisdiction in which such Lender has its
principal office or such Applicable Lending Office ("Excluded Taxes")); or (ii)
imposes or modifies any reserve, special deposit, minimum capital, capital ratio
or similar requirements relating to any extensions of credit or other assets of,
or any deposits with or other liabilities of, such Lender (including any of such
Loans or any deposits referred to in the definition of "Eurodollar Rate" in
Section 1.02 hereof), or any Commitment of such Lender; or (iii) imposes any
other condition affecting this Agreement or its Notes (or any of such extensions
of credit or liabilities) or Commitment.

          (b) SUSPENSION OF EURODOLLAR LOANS. If any Lender requests
compensation from the Company under Section 5.01(a), the Company may, by notice
to such Lender (with a copy to the Administrative Agent), suspend the obligation
of such Lender to make additional Loans of the Type with respect to which such
compensation is requested until the Regulatory Change giving rise to such
request ceases to be in effect (in which case the provisions of Section 5.04
shall be applicable). Without limiting the effect of the foregoing provisions of
this Section 5.01(b), in the event that, by reason of any Regulatory Change, any
Lender either (i) incurs Additional Costs based on or measured by the excess
above a specified level of the amount of a category of deposits or other
liabilities of such Lender which includes deposits by reference to which the
interest rate on Eurodollar Loans is determined as provided in this Agreement or
a category of extensions of credit or other assets of such Lender which includes
Eurodollar Loans or (ii) becomes subject to restrictions on the amount of such a
category of liabilities or assets which it may hold, then, such Lender may elect
by notice to the Company (with a copy to the Administrative Agent), to suspend
its obligation to make additional Eurodollar Loans until such Regulatory Change
ceases to be in effect (in which case the provisions of Section 5.04 shall be
applicable).

         (c) CAPITAL ADEQUACY. Without limiting the effect of Section 5.01(a)
and (b), but without duplication, after any Regulatory Change, the Company shall
pay directly to each Lender such amounts as such Lender may reasonably determine
to be necessary as a result of such Regulatory Change to compensate such Lender
(or its parent or holding company) for any costs which it determines are
attributable to the maintenance by such Lender (or its parent or holding company
or its Applicable Lending Office) of its capital in respect of its Commitment,
its Note, any Loans and/or any interest held by it in any Letter of Credit. Such
compensation shall include, without limitation, an amount equal to any reduction
of the rate of return on assets or equity of such Lender (or any Applicable
Lending Office) to a level below that which such Lender (or any Applicable
Lending Office) could have achieved but for such law, regulation,
interpretation, directive or request.

         SECTION 5.02 LIMITATION ON EURODOLLAR LOANS. Notwithstanding any other
provision of this Agreement, if, on or prior to the determination of any
Eurodollar Rate for any Interest Period:

         (a) the Administrative Agent determines (which determination shall be
conclusive, absent manifest error) that quotations of interest rates for the
relevant deposits referred to in the definition of "Eurodollar Rate" in Section
1.02 are not being provided in the relevant amounts or for the relevant
maturities for purposes of determining rates of interest for Eurodollar Loans as
provided herein; or

         (b) the Administrative Agent shall determine (which determination shall
be conclusive, absent manifest error) that the relevant rates of interest
referred to in the definition of "Eurodollar Rate" in Section 1.02 upon the
basis of which the rate of interest for Eurodollar Loans for such Interest



                                       32
<PAGE>   39




Period is to be determined are not sufficient to adequately cover the cost to
the Lenders of making or maintaining Eurodollar Loans;

then the Administrative Agent shall give the Company and each Lender prompt
notice thereof and so long as such condition remains in effect, the Lenders
shall be under no obligation to make additional Eurodollar Loans (in which case
the provisions of Section 5.04 shall be applicable).

         SECTION 5.03 ILLEGALITY. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans hereunder, then such Lender shall promptly notify the Company thereof
(with a copy to the Administrative Agent) and such Lender's obligation to make
Eurodollar Loans shall be suspended until such time as such Lender may again
make and maintain Eurodollar Loans (in which case the provisions of Section 5.04
shall be applicable).

         SECTION 5.04 BASE RATE LOANS PURSUANT TO SECTIONS 5.01, 5.02 AND 5.03.
If the obligation of any Lender to make Eurodollar Loans shall be suspended
pursuant to Section 5.01, 5.02 or 5.03 ("Affected Loans"), all Affected Loans
which would otherwise be made by such Lender shall be made instead as Base Rate
Loans (and, if an event referred to in Section 5.03 has occurred and such Lender
so requests by notice to the Company with a copy to the Administrative Agent,
all Affected Loans of such Lender then outstanding shall be automatically
converted into Base Rate Loans on the date specified by such Lender in such
notice). To the extent that Affected Loans are so made as (or converted into)
Base Rate Loans, all payments of principal which would otherwise be applied to
such Lender's Affected Loans shall be applied instead to the Loans so converted.

         SECTION 5.05 COMPENSATION. The Company shall pay to the Administrative
Agent for account of each Lender, upon the request of such Lender through the
Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense which such Lender determines are attributable to:

         (a) any payment, prepayment or conversion of a Eurodollar Loan for any
reason (including, without limitation, the acceleration of the Loans pursuant to
Section 10.01) on a date other than the last day of the Interest Period for such
Loan; or

         (b) any failure by the Company for any reason (including but not
limited to, the failure of any of the conditions precedent specified in Article
VI to be satisfied, but excluding failures arising out of the negligence, gross
negligence or wilful misconduct of a Lender or Agent) to borrow, continue or
convert a Eurodollar Loan from such Lender on the date for such borrowing,
continuation or conversion specified in the relevant notice of borrowing given
pursuant to Section 2.02.

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (x) the amount of interest
which otherwise would have accrued on the principal amount so paid, prepaid or
converted for the period from the date of such payment, prepayment or conversion
to the last day of the then current Interest Period for such Loan (or, in the
case of a failure to borrow, convert or continue, the Interest Period for such
Loan which would have commenced on the date specified for such borrowing,
conversion or continuation) at the applicable rate of interest for such Loan
provided for herein over (y) the interest component of the amount such Lender
would have bid in the London interbank market for Dollar deposits of leading
banks in amounts comparable to such



                                       33
<PAGE>   40




principal amount and with maturities comparable to such period (as reasonably
determined by such Lender).

         SECTION 5.06 ADDITIONAL COST IN RESPECT OF TAX.

         (a) PAYMENTS FREE AND CLEAR. Each payment to be made by the Company
hereunder or in connection herewith to any Agent or Lender or any other Person
shall be made free and clear of and without deduction for or on account of any
Tax unless the Company is required to make such payment subject to the deduction
or withholding of Tax, in which case (except for Excluded Taxes) the sum payable
by the Company in respect of which such deduction or withholding is required to
be made shall be increased to the extent necessary to ensure that, after the
making of such deduction or withholding, such Person receives and retains (free
from any liability in respect of any such deduction or withholding) a net sum
equal to the sum which it would have received and so retained had not such
deduction or withholding been made or required to be made.

         (b) OBLIGATION TO INDEMNIFY. If (i) any Agent or Lender is required by
law to make any payment on account of any Tax (except for Excluded Taxes) on or
in relation to any sum received or receivable hereunder by such Agent or Lender
or (ii) any liability in respect of any such payment is asserted, imposed,
levied or assessed against such Agent or Lender, then the Company shall promptly
pay to such Agent or Lender, as the case may be, any additional amounts
necessary to compensate it for such payment together with any interest,
penalties and expenses payable or incurred in connection therewith. If an Agent
or a Lender has paid over on account of Tax (other than Excluded Taxes) an
amount paid to it by the Company pursuant to the foregoing indemnification and
the amount so paid over is subsequently refunded to the recipient Agent or
Lender, in whole or in part, then the recipient Agent or Lender shall promptly
remit such amount refunded to the Company.

         (c) NOTICE OF CHANGES; PROOF OF PAYMENT. If at any time the Company is
required by law to make any deduction or withholding from any sum payable by it
hereunder or in connection herewith (or if thereafter there is any change in the
rates at which or the manner in which such deductions or withholdings are
calculated), the Company shall promptly notify the Administrative Agent thereof.
If the Company makes any payment hereunder or in connection herewith for which
it is required by law to make any deduction or withholding, it shall pay the
full amount to be deducted or withheld to the relevant taxation or other
authority within the time allowed for such payment under applicable law and
shall deliver to the Administrative Agent within thirty (30) days after it has
made such payment to the applicable authority (i) a receipt issued by such
authority or (ii) other evidence reasonably satisfactory to the Administrative
Agent evidencing the payment to such authority of all amounts so required to be
deducted or withheld from such payment.

         SECTION 5.07 AVOIDANCE OF TAXES AND ADDITIONAL COSTS.

         (a) CHANGE APPLICABLE FUNDING OFFICE. If a Lender makes any claim under
Section 5.01 or Section 5.06 in respect of Additional Costs or Taxes, such
Lender shall be obligated to use reasonable efforts to designate a different
Applicable Lending Office for the Commitment or the Loans of such Lender
affected by such event if such designation will avoid the need for, or reduce
the amount of, such compensation or the imposition of any Taxes and will not, in
the sole opinion of such Lender, be disadvantageous to such Lender; provided
that such Lender shall have no obligation to so designate an Applicable Lending
Office located in the United States.

<PAGE>   41



         (b) REPLACEMENT. If any Lender claims (i) payment of Additional Costs,
(ii) the inability to make or maintain the Eurodollar Rate for its Loans
pursuant to Section 5.01 or 5.03 (when such inability is not then being claimed
by substantially all of the Lenders) or (iii) payment of any Taxes pursuant to
Section 5.06, then the Company shall have the right, upon payment of such
requested Additional Costs or Taxes, if applicable, to (i) prepay the Loans made
by such Lender and terminate the Commitment of such Lender on a non pro rata
basis or (ii) subject to the approval of the Administrative Agent (such approval
not to be unreasonably withheld or delayed), find one or more Persons willing to
assume the Loans, Commitment and other obligations of such Lender and replace
such Lender pursuant to an Assignment and Acceptance. Any such assumption shall
be effected pursuant to Section 12.06(b). The Company shall not, however, be
entitled to replace any Lender if an event which with notice or lapse of time,
or both, would constitute a Default or an Event of Default exists at the time.

         SECTION 5.08 LENDER TAX REPRESENTATION. Each Lender represents that it
is either (a) a corporation organized under the laws of the United States of
America or any state thereof or (b) entitled to complete exemption from United
States withholding tax imposed on or with respect to any payments, including
fees, to be made to it pursuant to this Agreement, the Notes and the other Loan
Documents (i) under an applicable provision of a tax convention to which the
United States of America is a party or (ii) because it is acting through a
branch, agency or office in the United States of America and any payment to be
received by it hereunder is effectively connected with a trade or business in
the United States of America. Each Lender that is not a corporation organized
under the laws of the United States of America or any state thereof agrees to
provide to the Company and the Administrative Agent on the Effective Date, or on
the date of its delivery of the Assignment and Acceptance pursuant to which it
becomes a Lender, and at such other times as required by United States law, two
accurate and complete original signed copies of either Internal Revenue Service
Form 4224 (or successor form) certifying that all payments to be made to it
hereunder will be effectively connected to a United States trade or business or
Internal Revenue Service Form 1001 (or successor form) certifying that it is
entitled to the benefit of a tax convention to which the United States of
America is a party which completely exempts from United States withholding tax
all payments to be made to it hereunder. If a Lender determines, as a result of
any Regulatory Change or other change in its circumstances, that it is unable to
submit any form or certificate that it is obligated to submit pursuant to this
Section 5.08, or that it is required to withdraw or cancel any such form or
certificate previously submitted, it shall promptly notify the Company and the
Administrative Agent of such fact.

         SECTION 5.09 LIMITATION ON RIGHT TO COMPENSATION. Any demand for
compensation pursuant to Article V (other than Section 5.06) must be made on or
before six (6) months after the Lender incurs the expense, cost or economic loss
referred to or such Lender shall be deemed to have waived the right to such
compensation. Any demand for compensation pursuant to Section 5.06 must be made
on or before twelve (12) months after the Lender incurs the expense, cost or
economic loss referred to or such Lender shall be deemed to have waived the
right to such compensation.

         SECTION 5.10 COMPENSATION PROCEDURE. Each Lender will notify the
Administrative Agent and the Company of any event occurring after the date of
this Agreement which will entitle such Lender to compensation or indemnification
pursuant to this Article V as promptly as practicable after it obtains knowledge
thereof and determines to request such compensation. Each Lender will furnish
the Administrative Agent and the Company with a certificate setting forth the
basis and amount of each request by such Lender for compensation or
indemnification and specify the Section pursuant to which it is claiming
compensation or indemnification. Such certificate shall also include (i)
calculations in



                                       35
<PAGE>   42




reasonable detail computing such claim, and (ii) a statement from such Lender
that it is asserting its right for indemnity or compensation not solely with
respect to the Indebtedness outstanding under this Agreement, but is generally
making such claims with respect to similar borrowers in connection with
transactions similar to the one contemplated in this Agreement. Determinations
and allocations by any Lender for purposes of this Article V of the effect of
any Regulatory Change pursuant to Sections 5.01(a) or (b), or of the effect of
capital maintained pursuant to Section 5.01(c), on its costs or rate of return
of maintaining Loans or issuing or participating in Letters of Credit or its
obligation to make Loans or issue or participate in Letters of Credit, or on
amounts receivable by it in respect of Loans or such obligations, and of the
additional amounts required to compensate such Lender under Section 5.01, 5.05
or 5.06, shall be conclusive, provided that such determinations and allocations
are made on a reasonable basis.

                                   ARTICLE VI
                              CONDITIONS PRECEDENT

Eurodollar Loans which have matured in the normal course on the last day of an
Interest Period therefor or pursuant to Section 5.03) or of the Administrative

         (b) CERTIFICATION AS TO REPRESENTATIONS. Each notice of borrowing,

obligation of each of such Person, enforceable against it in accordance with
their terms, except as may be limited by applicable bankruptcy, insolvency,
reorganization or other similar laws affecting creditors' rights and general

<PAGE>   46



reasonably be expected to have a Material Adverse Effect, no authorizations,
approvals or consents of, and no filings or registrations with, any Governmental
Authority ("Approvals") are necessary for the execution, delivery or performance
by the Company or OEI-Louisiana of this Agreement, the Notes, the Loan Documents
to which it is a party or for the validity or enforceability thereof. It is
understood that continued performance by the Company and its Subsidiaries of
this Agreement and the other Loan Documents to which such Persons are a party
will require various Approvals, such as filings related to environmental
matters, ERISA matters, Taxes and intellectual property, filings required to
maintain corporate and similar standing and existence, filings pursuant to the
Uniform Commercial Code and other security filings and recordings, filings
required by the SEC, routine filings in the ordinary course of business, and

of remedies in connection with the Loan Documents.

         SECTION 7.07 USE OF LOANS AND LETTERS OF CREDIT. The proceeds of the

<PAGE>   47




indirectly through its Restricted Subsidiaries) will own in the aggregate, in
all material respects, the net interests in production attributable to the wells

to the maintenance, development and operations of such Properties in an amount
materially in excess of the working interest of such Properties set forth in the
Initial Reserve Reports. The Company has, or has caused its Restricted

no information, exhibit or report furnished to any Agent or Lender by the
Company or any of its Restricted Subsidiaries in connection with the negotiation
of this Agreement or any Loan Document contained any material misstatement of
fact or omitted to state a material fact or any fact necessary to make the

provisions of The Natural Gas Act or any other Federal or State law or any of

all necessary rate filings, certificate applications, well category filings,
interim collection filings and notices, and any other filings or certifications,
and have received all necessary regulatory authorizations (including without

<PAGE>   48



of them or others respecting said Oil and Gas Properties or production
therefrom) required under said laws and regulations with respect to all of the
Oil and Gas Properties or production therefrom so as not to have a Material
Adverse Effect. To the best of the Company's knowledge, said material rate
filings, certificate applications, well category filings, interim collection

operation and equipment requirements imposed by OPA or will comply with such
requirements scheduled to be imposed by OPA in the future during the term of

         SECTION 7.19 DEFAULTS. The Company and its Restricted Subsidiaries are
not in default and no event or circumstance has occurred which, but for the
passage of time or the giving of notice, or both, would constitute a default
under any agreement or other instrument to which either the Company or any of
its Restricted Subsidiaries is a party or by which it is bound in any manner
that could reasonably be expected to have a Material Adverse Effect. No Default
or Event of Default hereunder has occurred and is continuing.

         SECTION 7.20 COMPLIANCE WITH THE LAW. The Company and its Restricted
Subsidiaries have not violated any Governmental Requirement or failed to obtain
any license, permit, franchise or other governmental authorization necessary for
the ownership of any of their respective Properties or the conduct of their
respective business which violation or failure could reasonably be expected to
have a Material Adverse Effect.

         SECTION 7.21 RISK MANAGEMENT AGREEMENTS. Schedule 7.21 sets forth, as
of the Effective Date, a true and complete list of all Risk Management
Agreements (including commodity price swap agreements, forward agreements or
contracts of sale which provide for prepayment for deferred shipment or delivery
of oil, gas or other commodities) of the Company and its Restricted
Subsidiaries, the material terms thereof (including the type, term, effective
date, termination date and notional amounts or volumes), the net mark to market
value thereof, all credit support agreements relating thereto (including any
margin required or supplied), and the counterparty to each such agreement.

         SECTION 7.22 GAS IMBALANCES. As of the Effective Date, except as set
forth on Schedule 7.22 or on the most recent certificate delivered pursuant to
Section 8.05(c), on a net basis there are no gas imbalances, take or pay or
other prepayments with respect to the Company and its Restricted Subsidiaries'
Oil and Gas Properties which would require the Company or such Subsidiary to
deliver Hydrocarbons produced from the Oil and Gas Properties at some future
time without then or thereafter receiving substantially full payment therefor
exceeding 10,000,000 mcf of gas in the aggregate.

         SECTION 7.23 SOLVENCY. The Company (a) is not insolvent and will not be
rendered insolvent as a result of the execution, delivery and performance of the
Notes and this Agreement or the making of the Loans or issuance of Letters of
Credit hereunder, (b) is not engaged in business or a transaction, or about to
engage in a business or a transaction, for which it has unreasonably small
capital, and (c) does not intend to incur, or believe it will incur, debts that
will be beyond its ability to pay as such debts mature.

         SECTION 7.24 YEAR 2000 COMPLIANCE. Except where failure to do so would
not have a Material Adverse Effect, any reprogramming required to permit the
proper functioning, in and following the year 2000, of (i) the computer systems
of the Company and its Subsidiaries and (ii) equipment containing embedded
microchips (including systems and equipment supplied by others or with which the
systems of the Company and its Subsidiaries interface) and the testing of all
such systems and equipment, as so reprogrammed, will be completed by August 1,
1999. The cost to the Company and its Subsidiaries of such reprogramming and
testing and of the reasonably foreseeable consequences of year 2000 to the
Company and its Subsidiaries (including, without limitation, reprogramming
errors and the failure of others' systems or equipment) will not result in a
Default or Event of Default or otherwise have a Material Adverse Effect. Except
for such of the reprogramming referred to in the preceding sentence as may be
necessary, the computer and management information systems of the Company and
its Subsidiaries are and, with ordinary course upgrading and maintenance,



                                       43
<PAGE>   50




will continue for the term of this Agreement to be, sufficient to permit the
Company and its Subsidiaries to conduct their business without Material Adverse
Effect.

                                       45
<PAGE>   52



         (i) Promptly after the Company or any of its Restricted Subsidiaries is

senior financial officer of the Company: (i) to the effect that no Default or
Event of Default has occurred and is continuing (or, if any Default or Event of

it or on its income or profits or on any of its Property prior to the date on
which penalties attach thereto, except for any such tax, assessment, charge or
levy the payment of which is being contested in good faith and by proper
proceedings and against which

<PAGE>   53



adequate reserves are being maintained; (iv) permit representatives of any
Lender or the Administrative Agent, during normal business hours, to examine,
copy and make extracts from its books and records, inspect its Properties, and
discuss its business and affairs with its officers, all to the extent reasonably
requested by such Lender or the Administrative Agent (as the case may be); and
(v) keep insured by financially sound and reputable insurers all Property of a

capable of producing Hydrocarbons in economically reasonable amounts as
determined by the Company in its sole judgment, (ii) for sales or other
dispositions of Oil and Gas Properties permitted by Section 9.16, (iii) if such

         SECTION 8.04 ENVIRONMENTAL MATTERS. The Company shall, and shall cause
each of its Subsidiaries to, promptly notify the Administrative Agent and the
Lenders in writing of any existing, pending or threatened action, investigation
or inquiry by any Governmental Authority (of which the Company or any of its
Subsidiaries has actual knowledge) in connection with any Environmental Laws,
excluding routine testing and corrective action, which would involve a violation
of any Environmental Law or remedial obligation (individually or in the
aggregate) sufficient to have a Material Adverse Effect.

         SECTION 8.05 ENGINEERING REPORTS.

         (a) On or before February 28, 1999, and thereafter, March 15 of each
year commencing March 15, 2000, the Company shall furnish to the Technical
Agents and the Lenders a Reserve Report as of the preceding January 1st in form
and substance reasonably satisfactory to the Technical Agents. The January 1
Reserve Report of each year shall be comprised of two reports; one being
prepared by or under the supervision of certified independent petroleum
engineers or other independent petroleum consultant(s) reasonably acceptable to
the Technical Agents and evaluating Oil and Gas Properties comprising not less
than eighty percent (80%) of the SEC Value of the Oil and Gas Properties of the
Company and its Restricted Subsidiaries which Properties the Company desires to
have included in the Borrowing Base, and the other being prepared by or under
the supervision of the chief petroleum engineer of the Company (utilizing
substantially similar procedures to those used by its independent petroleum
engineers) and evaluating the Oil and Gas Properties comprising the remaining
SEC Value of the Oil and Gas Properties of the Company and its Restricted
Subsidiaries which Properties the Company desires to have included in the
Borrowing Base. Notwithstanding the foregoing, the January 1 Reserve Report
relating to any Oil and Gas Properties not located in the geographical
boundaries of the United States of America and Canada and surrounding waters
shall be prepared by certified independent petroleum engineers or other
independent petroleum consultant(s) reasonably acceptable to the Technical
Agents.

         (b) On or before September 15 of each year commencing September 15,
1999, the Company shall furnish to the Technical Agents and the Lenders a
Reserve Report prepared as of the immediately preceding July 1 by the chief
engineer of the Company (who shall certify such report to have been prepared in
accordance with the procedures used in the immediately preceding January 1
Reserve Report), which shall further evaluate the Oil and Gas Properties
evaluated in the immediately preceding Reserve Report. For any unscheduled
redetermination pursuant to Section 2.09(d), the Company shall provide such
Reserve Report (which shall be prepared by its chief engineer) with an "as of"
date as specified by the Required Lenders, as soon as possible, but in any event
no later than 75 days following the receipt of the request by the Administrative
Agent.

         (c) With the delivery of each Reserve Report required in Section
8.05(a) and (b), the Company shall provide to the Lenders a statement reflecting
(i) any material changes in the net revenue interest of each well or lease as
reflected in the Reserve Report delivered for the prior period, after giving
effect to all encumbrances listed therein from the net revenue interests as
reflected in such report, along with an explanation as to any material
discrepancies between the two net revenue interest disclosures, and (ii) that,
except as set forth on an exhibit thereto, on a net basis there are no gas
imbalances, take or pay or other prepayments with respect to their Oil and Gas
Properties evaluated in such Reserve Report which would require the Company or
any of its Restricted Subsidiaries to deliver Hydrocarbons produced from such
Oil and Gas Properties at some future time without then or thereafter receiving
full payment therefor.



                                       48
<PAGE>   55


         (d) If the Technical Agents desire to exclude an Oil and Gas Property
included in the Borrowing Base on the basis that title to such Oil and Gas
Property is unsatisfactory, the Administrative Agent shall give the Company
written notice thereof and the Company shall have 90 days to cure such defect.
If the Company is unable to cure any such title defect requested to be cured
within the 90-day period, such default shall not be a Default or an Event of
Default, but instead, if the aggregate value of all such Oil and Gas Properties
which have unsatisfactory title defects (and which have not previously resulted
in the invocation of the remedy set forth in this Section) constitutes 5% or
more of the then current amount of the Borrowing Base, the Technical Agents
shall have the right, by sending written notice to the Company, to reduce the
then outstanding Borrowing Base by an amount as reasonably determined by the
Technical Agents to reflect the impairment to the Borrowing Base caused by such
title defect. This adjustment to the Borrowing Base shall become effective
immediately after receipt of such notice.

         SECTION 8.06 STOCK OF RESTRICTED SUBSIDIARIES. Except as provided in
Section 9.08 and Exhibit D, the Company will at all times legally and
beneficially own all issued and outstanding shares of all classes of stock of
its Restricted Subsidiaries as listed on Exhibit D.

         SECTION 8.07 FURTHER ASSURANCES. The Company shall, and shall cause its
Restricted Subsidiaries to, cure promptly any defects in the creation and
issuance of the Notes and the execution and delivery of the Loan Documents,
including this Agreement. The Company and its Restricted Subsidiaries will at
their expense promptly execute and deliver to the Administrative Agent upon
request all such other and further documents, agreements and instruments (a) in
compliance with or accomplishment of the covenants and agreements of the Company
and OEI-Louisiana in the Loan Documents, including this Agreement, (b) to
further evidence and more fully describe the collateral, if any, intended as
security for the Notes, (c) to correct any omissions in the Loan Documents, or
more fully state the security obligations set out herein or in any of the Loan
Documents, (d) to perfect, protect or preserve any Liens created pursuant to any
of the Loan Documents, or (e) to make any recordings, to file any notices, or
obtain any consents, all as may be necessary or appropriate in connection
therewith.

         SECTION 8.08 PERFORMANCE OF OBLIGATIONS. The Company will pay the Notes
according to the reading, tenor and effect thereof; and the Company will and
will cause each Subsidiary to do and perform every act and discharge all of the
obligations to be performed and discharged by them under this Agreement and the
other Loan Documents, at the time or times and in the manner specified.

                                   ARTICLE IX
                               NEGATIVE COVENANTS

applicable exception, and such classification shall not be deemed to be a

                                   ARTICLE XI
                                   THE AGENTS

         SECTION 11.01 APPOINTMENT, POWERS AND IMMUNITIES. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent, the Syndication
Agent, the Documentation Agent, the Technical Agents and each Co-Agent to act as
its agent hereunder with such powers as are specifically delegated to it by the
terms of this Agreement or any Loan Document, together with such other powers as
are reasonably incidental thereto. (As of the Effective Date, the Co-Agents have
been delegated no specific powers or responsibilities under this Agreement,
except in their capacities as Lenders.) Each Agent (which term as used in this
sentence and in Section 11.05 and the first sentence of Section 11.06 shall
include reference to its Affiliates and its own and its Affiliates' officers,
directors, employees and agents): (a) shall have no duties or responsibilities
except those expressly set forth in this Agreement and the other Loan Documents
and shall not by reason of this Agreement or any other Loan Document be a
trustee for any other Agent or Lender; (b) shall not be responsible to any other
Agent or the Lenders (i) for the accuracy of any recitals, statements,
representations or warranties contained in this Agreement or any Loan Document
or in any certificate or other document referred to or provided for in, or
received by any of them under, this Agreement; (ii) for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement, any
Note or any Loan Document or any other document referred to or provided for
herein; or (iii) for any failure by the Company, OEI-Louisiana or any other
Person to perform any of its obligations hereunder or thereunder; (c) shall not
be required to initiate or conduct any litigation or collection proceedings
hereunder except as may be expressly required under this Agreement or any other
Loan Document; and (d) shall not be responsible for any action taken or omitted
to be taken by it hereunder or under any other Loan Document, except for its own
gross negligence or willful misconduct. The Agents may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it in good faith. Each Agent
may deem and treat the payee of any Note as the holder thereof for all purposes
hereof unless and until a written notice of the



                                       62
<PAGE>   69



assignment or transfer thereof shall have been filed with the Administrative
Agent, together with the written consent of the Company to such assignment or
transfer.

         SECTION 11.02 RELIANCE BY AGENTS. Each Agent shall be entitled to rely:
(a) upon any certification, notice or other communication (including any thereof
by telephone, telex, telegram or cable) believed by it to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person or Persons;
and (b) upon advice and statements of legal counsel, independent accountants and
other experts selected by any Agent in good faith. As to any matters not
expressly provided for by this Agreement or any Loan Document, each Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder in accordance with instructions signed by the Majority Lenders; and
such instructions of the Majority Lenders and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders.

         SECTION 11.03 DEFAULTS. No Agent shall be deemed to have knowledge of
the occurrence of a Default (other than, in the case of the Administrative
Agent, the non-payment of principal of or interest on Loans or of fees or the
non-payment of reimbursement obligations of the Company in connection with
Letters of Credit) unless it has received notice from either a Lender or the
Company specifying such Default and stating that such notice is a "Notice of
Default". In the event that any Agent receives such a notice of the occurrence
of a Default, it shall promptly give notice to the Administrative Agent who
shall thereafter give prompt notice thereof to the Lenders.

         SECTION 11.04 RIGHTS AS A LENDER. With respect to its Commitment and
the Loans made by it and the Letters of Credit issued by it or in which it is
participating, each Agent (and any successor acting as an Agent) in its capacity
as a Lender hereunder shall have the same rights and powers hereunder as any
other Lender and may exercise the same as though it were not acting as an Agent,
and the term "Lender" or "Lenders" shall include each Agent in its individual
capacity. Each Agent (and any successor acting as an Agent) and its Affiliates
may (without having to account therefor to any other Agent or Lender) accept
deposits from, lend money to and generally engage in any kind of banking, trust
or other business with the Company and its Subsidiaries or any of the Company's
Affiliates as if it were not acting as an Agent. Each Agent and its Affiliates
may accept fees and other consideration from the Company or any of its
Affiliates for services in connection with this Agreement, any Loan Document or
otherwise without having to account for the same to any other Agent or the
Lenders.

         SECTION 11.05 INDEMNIFICATION. The Lenders agree to indemnify each
Agent (to the extent not reimbursed under Section 12.03, but without limiting
the obligations of the Company under Section 12.03), ratably in accordance with
the aggregate principal amount of the Loans made by the Lenders (or, if no Loans
are at the time outstanding, ratably in accordance with their respective
Commitments), for any and all Indemnity Matters of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against such Agent
in any way relating to or arising out of: (a) this Agreement or any other Loan
Document or the transactions contemplated hereby and thereby (including, without
limitation, the costs and expenses which the Company is obligated to pay under
Section 12.03 but excluding, unless a Default has occurred and is continuing,
normal administrative costs and expenses incident to the performance of its
agency duties hereunder); or (b) the enforcement of any of the terms hereof or
of any other Loan Document; provided that no Lender shall be liable for any
Indemnity Matter to the extent it arises from the gross negligence or willful
misconduct of the Person to be indemnified; and provided further that no Lender
shall be liable for any Indemnity Matters arising solely by reason of claims
among the Agents and their shareholders. THE FOREGOING



                                       63
<PAGE>   70

INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES NOTWITHSTANDING THE SOLE OR
CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR
PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT
LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT
(SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF
STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNIFIED
PARTIES. TO THE EXTENT THAT AN INDEMNIFIED PARTY IS FOUND BY A FINAL,
NON-APPEALABLE JUDGMENT OF A COURT OR BY AGREEMENT TO HAVE COMMITTED AN ACT OF
GROSS NEGLIGENCE OR WILFUL MISCONDUCT, THIS CONTRACTUAL OBLIGATION OF
INDEMNIFICATION SHALL CONTINUE BUT SHALL ONLY EXTEND TO THE PORTION OF THE CLAIM
THAT IS DEEMED TO HAVE OCCURRED BY REASON OF EVENTS OTHER THAN THE GROSS
NEGLIGENCE OR WILFUL MISCONDUCT OF THE PARTY SEEKING INDEMNIFICATION. IN
ADDITION, THE FOREGOING INDEMNITIES EXCLUDE ALL INDEMNITY MATTERS ARISING SOLELY
BY REASON OF CLAIMS AMONG INDEMNIFIED PARTIES AND THEIR SHAREHOLDERS.

         SECTION 11.06 NON-RELIANCE ON AGENTS AND OTHER LENDERS. Each Lender
agrees: (a) that it has, independently and without reliance on any Agent or any
other Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Company and its Subsidiaries
and decision to enter into this Agreement; and (b) that it will, independently
and without reliance upon any Agent or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own analysis and decisions in taking or not taking action under this
Agreement or any other Loan Document. No Agent shall be required to keep itself
informed as to the performance or observance by the Company, OEI-Louisiana or
any other Person of its obligations under this Agreement or any other Loan
Document or document referred to or provided for herein or to inspect the
Properties or books of the Company and its Subsidiaries. Except for notices,
reports and other documents and information expressly required to be furnished
to the Lenders by an Agent hereunder or under a Loan Document, no Agent shall
have any duty or responsibility to provide any other Agent or Lender with any
credit or other information concerning the affairs, financial condition or
business of the Company and its Subsidiaries (or any of their Affiliates) which
may come into the possession of such Agent or any of their Affiliates.

         SECTION 11.07 ACTION BY AGENTS. Except for action or other matters
expressly required of an Agent hereunder, such Agent shall in all cases be fully
justified in failing or refusing to act hereunder unless it shall (i) receive
written instructions from the Majority Lenders specifying the action to be
taken, and (ii) be indemnified to its satisfaction by the Lenders against any
and all liability and expenses which may be incurred by it by reason of taking
or continuing to take any such action, and such instructions of the Majority
Lenders and any action taken or failure to act pursuant thereto shall be binding
on all of the Lenders. If a Default has occurred and is continuing, the
Administrative Agent shall take such action with respect to such Default as
shall be directed by the Majority Lenders in the written instructions (with
indemnities) described in this Section 11.07, provided that, unless and until
the Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default as it shall deem advisable in
the best interests of the Lenders. In no event, however, shall the
Administrative Agent be required to take any action which exposes it to personal
liability or which is contrary to this Agreement and the Loan Documents or
applicable law.

         SECTION 11.08 RESIGNATION OR REMOVAL OF AGENTS. Subject to the
appointment and acceptance of a successor Agent as provided in this Section
11.08, any Agent may resign at any time by giving notice thereof to the Lenders
and the Company, and any Agent may be removed at any time, for cause,



                                       64
<PAGE>   71



by the Required Lenders. Upon any such resignation or removal, the Required
Lenders, with the consent of the Company (which consent shall not be
unreasonably withheld or delayed), shall have the right to appoint a successor
Agent. If no successor shall have been so appointed by the Required Lenders and
shall have accepted such appointment within 30 days after either the retiring
Agent's giving of notice of resignation or the Required Lenders' removal of the
retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint
its successor. Upon the acceptance of any appointment as an Agent hereunder by a
successor, such successor shall thereupon succeed to and become vested with all
the rights, powers, privileges and duties of the retiring Agent and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation or removal hereunder, the provisions of this
Article XI shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as an Agent.

                                   ARTICLE XII
                                  MISCELLANEOUS

         SECTION 12.01 WAIVER. No failure on the part of any Agent or any Lender
to exercise, no delay in exercising, and no course of dealing with respect to,
any right, power or privilege under this Agreement or any Loan Document shall
operate as a waiver thereof; and no single or partial exercise of any right,
power or privilege under this Agreement or any Loan Document shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The remedies provided herein are cumulative and not exclusive of any
remedies provided by law.

         SECTION 12.02 NOTICES. All notices and other communications provided
for herein and in the other Loan Documents (including, without limitation, any
modifications of, or waivers or consents under, this Agreement or the other Loan
Documents) shall be given or made by telecopy, telegraph, cable or in writing
and telecopied, telegraphed, cabled, mailed or delivered to the intended
recipient at the "Address for Notices" specified below its name on the signature
pages hereof; or, as to any party, at such other address as shall be designated

this Agreement, all such communications shall be deemed to have been duly given
when transmitted by telecopier, delivered to the telegraph or cable office or
personally delivered or, in the case of a mailed notice, upon receipt, in each
case given or addressed as aforesaid.

         SECTION 12.03 PAYMENT OF EXPENSES, INDEMNITIES, ETC. The Company agrees
to:

         (a) whether or not the transactions hereby contemplated are
consummated, pay all reasonable expenses of the Administrative Agent in the
administration (both before and after the execution hereof and including advice
of counsel as to the rights and duties of the Agents and the Lenders with
respect thereto) of, and in connection with the negotiation, investigation,
preparation, execution and delivery of, recording or filing of, preservation of
rights under, enforcement of, and refinancing, renegotiation or restructuring

waiver or consent relating thereto (including, without limitation, the
reasonable fees and disbursements of counsel for the Administrative Agent and in
the case of enforcement for any of the Lenders); and promptly reimburse each
Agent or Lender for all amounts expended, advanced or incurred by such Agent or
Lender to satisfy any obligation of the Company or OEI-Louisiana under this

of "Applicable Margin" or reduces the interest rate (other than as a result of
waiving the applicability of any post-Default increases in such rates), modifies
the amount of principal due on any payment date or modifies the payment dates
for payments of either principal or interest on any Loan, modifies any fees
payable under any of the Loan Documents, increases the Borrowing Base or
releases or modifies the obligations of OEI-Louisiana under the Guaranty
Agreement shall be effective without consent of all Lenders; and (d) no
amendment, modification or waiver which modifies the rights, duties or
obligations or fees of any Agent shall be effective without the consent of such
Agent.

         SECTION 12.05 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

         SECTION 12.06 ASSIGNMENTS AND PARTICIPATIONS.

         (a) The Company may not assign its rights or obligations hereunder,
under the Notes or under any Letter of Credit Agreement without the prior
consent of all of the Lenders and the Administrative Agent.

         (b) Each Lender may, upon the written consent of the Company and the
Administrative Agent which consent shall not be unreasonably withheld or delayed
(provided that if an Event of Default has occurred and is continuing,
assignments may be made hereunder without the Company's consent), assign to one
or more assignees all or a portion of its rights and obligations under this
Agreement pursuant to an Assignment and Acceptance Agreement substantially in
the form of Exhibit G (an "Assignment and Acceptance"); provided that (i) any
such assignment shall be in the aggregate amount of at least $5,000,000, the
entire amount of a Lender's Commitment, if less, or such other lesser amount to
which the Company has consented, and (ii) the assignee shall pay to the
Administrative Agent a processing and recordation fee of $3,500; provided that
such fee shall not be payable in conjunction with any assignments occurring
within 30 days of the Effective Date. Any such assignment will become effective
upon the issuance by the Administrative Agent of a letter of



                                       67
<PAGE>   74




acknowledgment reflecting such assignment and the resultant effects thereof on
the Commitments of the assignor and assignee, and the principal amount
outstanding of the Loans owed to the assignor and assignee, the Administrative
Agent hereby agreeing to effect such issuance no later than five (5) Business
Days after its receipt of an Assignment and Acceptance executed by all parties
thereto. Promptly after receipt of an Assignment and Acceptance executed by all
parties thereto, the Administrative Agent shall send to the Company a copy of
such executed Assignment and Acceptance. Upon receipt of such executed
Assignment and Acceptance, the Company, will, at its own expense, execute and
deliver new Notes to the assignor and/or assignee, as appropriate, in accordance
with their respective interests as they appear on the Administrative Agent's
letter of acknowledgment. Upon the effectiveness of any assignment pursuant to
this Section, the assignee will become a "Lender," if not already a "Lender,"
for all purposes of this Agreement and the other Loan Documents. Subject to the
terms of Section 12.10 of this Agreement and the Sections referred to therein,
the assignor shall be relieved of its obligations hereunder to the extent of
such assignment (and if the assigning Lender no longer holds any rights or
obligations under this Agreement, such assigning Lender shall cease to be a
"Lender" hereunder). The Administrative Agent will prepare on the last Business
Day of each month during which an assignment has become effective pursuant to
this Section 12.06(b), a new Annex I giving effect to all such assignments
effected during such month, and will promptly provide the same to the Company
and each of the Lenders.

         (c) Each Lender may transfer, grant or assign participations in all or
any part of such Lender's interests hereunder pursuant to this subsection to any
Person, provided that: (i) such Lender shall remain a "Lender" for all purposes
of this Agreement and the transferee of such participation shall not constitute
a "Lender" hereunder; and (ii) no participant under any such participation shall
have rights to approve any amendment to or waiver of this Agreement, the Notes
or any Loan Document except to the extent such amendment or waiver would (x)
extend the Termination Date, (y) reduce the principal amount of any Loan
outstanding , the interest rate (other than as a result of waiving the
applicability of any post-default increases in interest rates) or fees
applicable to any of the Commitments or Loans in which such participant is
participating, or postpone the payment of any thereof, or (z) release
OEI-Louisiana from its obligations under the Guaranty Agreement. In the case of
any such participation, the participant shall not have any rights under this
Agreement or any of the Loan Documents (the participant's rights against the
granting Lender in respect of such participation to be those set forth in the
agreement with such Lender creating such participation), and all amounts payable
by the Company hereunder shall be determined as if such Lender had not sold such
participation, provided that if such participant has made and complied with the
representations contained in Section 5.08, such participant shall be entitled to
receive additional amounts under Article V on the same basis as if it were a
Lender other than amounts paid by reason of such participant's noncompliance
with Section 5.08. In addition, each agreement creating any participation must
include agreements by the participant to be bound by the provisions of Section
12.14 if such participant is to receive any confidential information.

         (d) Notwithstanding any other provisions of this Section 12.06, no
transfer or assignment of the interests or obligations of any Lender hereunder
or any grant of participations therein shall be permitted if such transfer,
assignment or grant would require the Company to file a registration statement
with the SEC or to qualify the Loans or any interest therein under the "Blue
Sky" laws of any state.

         (e) The Lenders may furnish any information concerning the Company in
the possession of the Lenders from time to time to assignees and participants
(including prospective assignees and



                                       68
<PAGE>   75




participants); provided that, such Persons agree in writing to be bound by the
provisions of Section 12.14 hereof.

         (f) Notwithstanding anything in this Section 12.06 to the contrary, any
Lender may assign and pledge all or any of its Notes to any Federal Reserve Bank
or the United States Treasury as collateral security pursuant to Regulation A of
the Board of Governors of the Federal Reserve System and any operating circular
issued by such Federal Reserve System and/or such Federal Reserve Bank. No such
assignment and/or pledge shall release the assigning and/or pledging Lender from
its obligations hereunder.

         SECTION 12.07 INVALIDITY. In the event that any one or more of the
provisions contained in the Notes, this Agreement or in any other Loan Document
shall for any reason be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other
provision of such Note, this Agreement or any other Loan Document.

         SECTION 12.08 ENTIRE AGREEMENT. The Notes, this Agreement, the Guaranty
Agreement and the other Loan Documents embody the entire agreement and
understanding between the Lenders, the Agents, the Company and its Subsidiaries
party thereto and supersede all prior agreements and understandings between such
parties relating to the subject matter hereof and thereof. There are no
unwritten oral agreements between the parties.

         SECTION 12.09 REFERENCES. The words "herein," "hereof," "hereunder" and
other words of similar import when used in this Agreement refer to this
Agreement as a whole, and not to any particular article, section or subsection.
Any reference herein to a Section shall be deemed to refer to the applicable
Section of this Agreement unless otherwise stated herein. Any reference herein
to an exhibit or schedule shall be deemed to refer to the applicable exhibit or
schedule attached hereto unless otherwise stated herein.

         SECTION 12.10 SURVIVAL. The obligations of the Company, each Agent and
the Lenders under Sections 5.01, 5.05, 5.06, 12.03 and 12.14 shall survive the
repayment of the Loans, the expiration of the Letters of Credit and the
termination of the Commitments and any assignment by a Lender of all its Loans
or Commitments pursuant to Section 12.06(b).

         SECTION 12.11 CAPTIONS. Captions and section headings appearing herein
or any Loan Document are included solely for convenience of reference and are
not intended to affect the interpretation of any provision of this Agreement or
such Loan Document.

         SECTION 12.12 COUNTERPARTS. This Agreement and each Loan Document
(other than the Notes) may be executed in any number of counterparts, all of
which taken together shall constitute one and the same instrument and any of the
parties hereto may execute this Agreement or any such Loan Document by signing
any such counterpart.

         SECTION 12.13 GOVERNING LAW; SUBMISSION TO JURISDICTION.

         (a) THIS AGREEMENT AND THE NOTES (INCLUDING, BUT NOT LIMITED TO, THE
VALIDITY AND ENFORCEABILITY HEREOF AND THEREOF) SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS.




                                       69

         (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT, THE
NOTES OR THE OTHER LOAN DOCUMENTS TO WHICH THE COMPANY IS A PARTY MAY BE BROUGHT
IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE
SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT,
THE COMPANY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS
SUBMISSION TO JURISDICTION IS NONEXCLUSIVE AND DOES NOT PRECLUDE THE
ADMINISTRATIVE AGENT OR ANY LENDER FROM OBTAINING JURISDICTION OVER THE COMPANY
IN ANY COURT OTHERWISE HAVING JURISDICTION.

         (c) The Company irrevocably consents to the service of process of any
of the aforementioned courts in any such action or proceeding by the mailing of
copies thereof by registered or certified mail, postage prepaid, to it, as the
case may be, at its said address, such service to become effective 30 days after
such mailing.

         (d) Nothing herein shall affect the right of any Agent or any Lender or
any holder of a Note to serve process in any other manner permitted by law or to
commence legal proceedings or otherwise proceed against the Company in any other
jurisdiction.

         (e) THE COMPANY, EACH AGENT AND EACH LENDER HEREBY (I) IRREVOCABLY AND
UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN
ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY LOAN DOCUMENT
AND FOR ANY COUNTERCLAIM THEREIN; (II) IRREVOCABLY WAIVE, TO THE MAXIMUM EXTENT
NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH
LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES
OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (III) CERTIFY THAT NO PARTY
HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (IV)
ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN
DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.13.

         SECTION 12.14 CONFIDENTIALITY. Each Lender and each Agent agree that
they will use their best efforts not to disclose without the prior written
consent of the Company (other than to their employees, auditors or counsel or to
another Lender if the Lender or such Lender's holding or parent company or the
Administrative Agent in its sole discretion determines that any such party
should have access to such information) any information with respect to the
Company or any of its Subsidiaries which is furnished pursuant to this Agreement
and which is designated by the Company to the Lenders and the Administrative
Agent in writing as confidential, provided that any Lender and the
Administrative Agent may disclose any such information (a) as has become
generally available to the public, (b) as may be required or appropriate in any
report, statement or testimony submitted to any municipal, state or Federal
regulatory body having or claiming to have jurisdiction over such Lender or the
Administrative



                                       70
<PAGE>   77



Agent or to the Federal Reserve Board, the Federal Deposit Insurance Company,
National Association of Insurance Commissioners or similar organizations
(whether in the United States or elsewhere) or their successors, (c) as may be
required or appropriate in response to any summons or subpoena or in connection
with any litigation, (d) in order to comply with any law, order, regulation or
ruling applicable to such Lender or the Administrative Agent, and (e) to the
prospective transferee in connection with any contemplated transfer of any of
the Notes or any interest therein by such Lender or to any Affiliate of a
Lender, provided that such prospective transferee, participant or Affiliate
executes an agreement with the Company containing provisions substantially
identical to those contained in this Section.

         SECTION 12.15 INTEREST. It is the intention of the parties hereto that
each Agent and Lender shall conform strictly to usury laws applicable to it.
Accordingly, if the transactions contemplated hereby would be usurious as to any
Agent or Lender under laws applicable to it (including the laws of the United
States of America and the State of Texas or any other jurisdiction whose laws
may be mandatorily applicable to such Agent or Lender notwithstanding the other
provisions of this Agreement), then, in that event, notwithstanding anything to
the contrary in the Notes, this Agreement or any other Loan Document, it is
agreed as follows: (a) the aggregate of all consideration which constitutes
interest under law applicable to any Agent or Lender that is contracted for,
taken, reserved, charged or received by such Agent or Lender under the Notes,
this Agreement or under any of the other aforesaid Loan Documents or agreements
or otherwise in connection with the Notes shall under no circumstances exceed
the maximum amount allowed by such applicable law, and any excess shall be
canceled automatically and if theretofore paid shall be credited by such Agent
or Lender on the principal amount of the Indebtedness (or, to the extent that
the principal amount of the Indebtedness shall have been or would thereby be
paid in full, refunded by such Agent or Lender to the Company); and (b) in the
event that the maturity of the Notes is accelerated by reason of an election of
the holder thereof resulting from any Event of Default under this Agreement or
otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Agent or
Lender may never include more than the maximum amount allowed by such applicable
law, and excess interest, if any, provided for in this Agreement or otherwise
shall be canceled automatically by such Agent or Lender as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited by such
Agent or Lender on the principal amount of the Indebtedness (or, to the extent
that the principal amount of the Indebtedness shall have been or would thereby
be paid in full, refunded by such Agent or Lender to the Company). All sums paid
or agreed to be paid to any Agent or Lender for the use, forbearance or
detention of sums due hereunder shall, to the extent permitted by law applicable
to such Agent or Lender, be amortized, prorated, allocated and spread throughout
the term of the Loans evidenced by the Notes until payment in full so that the
rate or amount of interest on account of any Loans or other amounts hereunder
does not exceed the maximum amount allowed by such applicable law. If at any
time and from time to time (i) the amount of interest payable to any Agent or
Lender on any date shall be computed at the Highest Lawful Rate applicable to
such Agent or Lender pursuant to this Section 12.15 and (ii) in respect of any
subsequent interest computation period the amount of interest otherwise payable
to such Agent or Lender would be less than the amount of interest payable to
such Agent or Lender computed at the Highest Lawful Rate applicable to such
Agent or Lender, then the amount of interest payable to such Agent or Lender in
respect of such subsequent interest computation period shall continue to be
computed at the Highest Lawful Rate applicable to such Agent or Lender until the
total amount of interest payable to such Agent or Lender shall equal the total
amount of interest which would have been payable to such Agent or Lender if the
total amount of interest had been computed without giving effect to this Section
12.15.




                                       71
<PAGE>   78



         To the extent that the Texas Credit Title is relevant to any Agent or
Lender for the purpose of determining the Highest Lawful Rate, each such Agent
and Lender hereby elects to determine the applicable rate ceiling under the
Texas Credit Title by the weekly rate ceiling from time to time in effect.

         SECTION 12.16 EFFECTIVENESS. This Agreement and the Loan Documents
shall not be effective until the date (the "Effective Date") that (a) each of
them is delivered to the Administrative Agent in the State of Texas, (b) each of
them is accepted by the Administrative Agent in such State, and (c) the
conditions set forth in Section 6.01 have been satisfied or waived.

         SECTION 12.17 SURVIVAL OF OBLIGATIONS. To the extent that any payments
on the Indebtedness or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy
law, common law or equitable cause, then to such extent, the Indebtedness so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and the Administrative Agent's (held for the benefit of the Agents
and the Lenders) Liens (if any), rights, powers and remedies under this
Agreement and each Loan Document shall continue in full force and effect. In
such event, each Loan Document shall be automatically reinstated and the Company
shall, and shall cause each of its Restricted Subsidiaries to, take such action
as may be reasonably requested by the Administrative Agent and the Lenders to
effect such reinstatement.

         SECTION 12.18 DEBT CHARACTERIZATION FOR INDENTURE PURPOSES; SPECIFIED
OR DESIGNATED SENIOR INDEBTEDNESS.

         (a) If so designated by the Company in its internal records (which
designation may be made in its sole and absolute discretion), any Debt incurred
hereunder and all guarantees thereof shall constitute "Indebtedness" other than
"Permitted Indebtedness" or "Permitted Subsidiary Indebtedness" (as such terms
are defined in the 95 Indenture, the 96 Indenture, the 97 Indenture and the 98
Senior Subordinated Indenture) for purposes of any Indenture.

         (b) The Company hereby represents and warrants that:

         (i) this Agreement, the Notes, the Loan Documents and the obligations
         of the Company and OEI-Louisiana hereunder and thereunder are "Senior
         Indebtedness" and "Specified Senior Indebtedness" and "Guarantor Senior
         Indebtedness" and "Specified Guarantor Senior Indebtedness",
         respectively, under and for purposes of the 95 Indenture; and

         (ii) this Agreement, the Notes, the Loan Documents and the obligations
         of the Company and OEI-Louisiana hereunder and thereunder are "Senior
         Indebtedness" and "Designated Senior Indebtedness" and "Guarantor
         Senior Indebtedness" and "Designated Guarantor Senior Indebtedness",
         respectively, under and for purposes of the 96 Indenture, the 97
         Indenture and the 98 Senior Subordinated Indenture;

         and that as such, the Agents and the Lenders are entitled to the rights
         and privileges afforded holders of Senior Indebtedness, Specified
         Senior Indebtedness or Designated Senior Indebtedness, Senior Guarantor
         Indebtedness, Specified Guarantor Senior Indebtedness or Designated
         Guarantor Senior Indebtedness under each of said Indentures.




                                       72
<PAGE>   79




         (c) To the extent permitted and required by the terms of any Indenture
or any other instrument evidencing Subordinated Debt which the Company may
hereafter incur, the Company covenants and agrees to give (and maintain without
revocation) any notices or designations to the trustee, agent or other
representative thereunder designating (A) the Indebtedness as "senior
indebtedness", "specified senior indebtedness", "designated senior indebtedness"
or any other similar designation, and (B) the Guaranty Agreement as "guarantor
senior indebtedness", "specified guarantor senior indebtedness", "designated
guarantor senior indebtedness" or any other similar designation.

         SECTION 12.19 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS
AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS,
CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY
INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING
ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED
THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT
IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT
IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD
NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT
"CONSPICUOUS."

         SECTION 12.20 INTERCREDITOR AGREEMENT. Each Agent and Lender hereby
authorizes the Administrative Agent to execute and deliver on its behalf a
Master Release acknowledging the termination of the Intercreditor Agreement and
the obligations of the parties thereunder, other than those obligations which by
their terms expressly survive such termination.

                                 THE GUARANTY

         SECTION 2.01 OBLIGATIONS GUARANTEED. The Guarantor hereby irrevocably
and unconditionally guarantees the prompt payment at maturity of the
Obligations.

         SECTION 2.02 NATURE OF GUARANTY. This guaranty is an absolute,
irrevocable, completed and continuing guaranty of payment and not a guaranty of
collection, and no notice of the Obligations or any extension of credit already
or hereafter contracted by or extended to the Company need be given to the
Guarantor. This guaranty may not be revoked by the Guarantor and shall continue
to be effective with respect to debt under the Obligations arising or created
after any attempted revocation by the Guarantor and shall remain in full force
and effect until the Obligations are paid in full and the Aggregate Commitments
are terminated, notwithstanding that from time to time prior thereto no
Obligations may be outstanding. The Company, the Agents and the Lenders may
modify, alter, rearrange, extend for any period and/or renew from time to time,
the Obligations and the Agents and the Lenders may waive any Defaults or Events
of Default without notice to the Guarantor and in such event the Guarantor will
remain fully bound hereunder on the Obligations. Subject to the terms of the
Credit Agreement, this Guaranty Agreement may be enforced by the Agents and/or
the Lenders and any subsequent holder of the Obligations and shall not be
discharged by the assignment or negotiation of all or part of the Obligations.
The Guarantor hereby expressly waives presentment, demand, notice of
non-payment, protest and notice of protest and dishonor, notice of Event of
Default, notice of intent to accelerate the maturity and notice of acceleration
of the maturity and any other notice in connection with the Obligations, and
also notice of acceptance of this Guaranty Agreement, acceptance on the part of
the Agents and the Lenders being conclusively presumed by their request for
this Guaranty Agreement and delivery of the same to the Administrative Agent.

         SECTION 2.03 LENDERS' RIGHTS. Subject to the terms of the Credit
Agreement, the Guarantor authorizes the Lenders (or the Administrative Agent on
behalf of the Lenders), without notice or demand and without affecting the
Guarantor's obligation hereunder, to take and hold agreed-upon security for the
payment of the Obligations, and exchange, enforce, waive and release any such
security; and to apply such security and direct the order or manner of sale
thereof as the Agents and the Lenders in their discretion may determine; and to
obtain a guaranty of the Obligations from any one or more Persons and at any
time or times to enforce, waive, rearrange, modify, limit or release any of
such other Persons from their obligations under such guaranties.

         SECTION 2.04 GUARANTOR'S WAIVERS. The Guarantor waives any right to
require the Agents and the Lenders to (a) proceed against the Company or any
other Person liable on the Obligations, (b) enforce their rights against any
other guarantor of the Obligations, (c) proceed or enforce their rights against
or exhaust any security given to secure the Obligations, (d) have the Company
joined with the Guarantor in any suit arising out of this Guaranty Agreement
and/or the Obligations, or (e) pursue any other remedy whatsoever. Neither



                                       2
<PAGE>   5

the Agents nor the Lenders shall be required to mitigate damages or take any
action to reduce, collect or enforce the Obligations. The Guarantor waives any
defense arising by reason of any disability, lack of corporate authority or
power, or other defense of the Company or any other guarantor of the
Obligations, and shall remain liable hereon regardless of whether the Company
or any other guarantor be found not liable thereon for any reason.

         SECTION 2.05 MATURITY OF OBLIGATIONS; PAYMENT. The Guarantor agrees
that if the maturity of the Obligations is accelerated by bankruptcy or
otherwise, such maturity shall also be deemed accelerated for the purpose of
this Guaranty Agreement without demand or notice to the Guarantor. The
Guarantor will, forthwith upon notice from the Administrative Agent of the
Company's failure to pay the Obligations at maturity, pay to the Administrative
Agent for the benefit of the Agents and the Lenders at the Administrative
Agent's Principal Office, the amount due and unpaid by the Company and
guaranteed hereby. The failure of the Administrative Agent to give this notice
shall not in any way release the Guarantor hereunder.

         SECTION 2.06 LENDERS' EXPENSES. If the Guarantor fails to pay the
Obligations after notice from the Administrative Agent of the Company's failure
to pay any Obligations at maturity (whether by acceleration or otherwise), and
if the Agents or the Lenders obtain the services of an attorney for collection
of amounts owing by the Guarantor hereunder, or obtain advice of counsel in
respect of any of their rights under this Guaranty Agreement, or if suit is
filed to enforce this Guaranty Agreement, or if proceedings are had in any
bankruptcy, receivership or other judicial proceedings for the establishment or
collection of any amount owing by the Guarantor hereunder, or if any amount
owing by the Guarantor hereunder is collected through such proceedings, the
Guarantor agrees to pay to the Administrative Agent at its Principal Office the
reasonable attorneys' fees of the Agents and the Lenders.

         SECTION 2.07 OBLIGATION. It is expressly agreed that the obligation of
the Guarantor for the payment of the Obligations guaranteed hereby shall be
primary and not secondary.

         SECTION 2.08 EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING THE
GUARANTOR'S OBLIGATIONS. The Guarantor hereby consents and agrees to each of
the following to the fullest extent permitted by law, agrees that its
obligations under this Guaranty Agreement shall not be released, diminished,
impaired, reduced or adversely affected by any of the following, and waives any
rights (including without limitation rights to notice) which it might otherwise
have as a result of or in connection with any of the following:

         (a) Modifications, etc. Any renewal, extension, modification, or
increase in the amount of the Aggregate Commitments as in effect on the
Effective Date, decrease, alteration or rearrangement of all or any part of the
Obligations, any Loan Document or any instrument executed in connection
therewith, or any contract or understanding between the Company, any Agent
and/or the Lenders, or any other Person, pertaining to the Obligations;

         (b) Adjustment, etc. Any adjustment, indulgence, forbearance or
compromise that might be granted or given by the Agents or the Lenders to the
Company, the Guarantor or any Person liable on the Obligations;

         (c) Condition of the Company or the Guarantor. The insolvency,
bankruptcy, arrangement, reorganization, adjustment, composition, liquidation,
disability, dissolution or lack of power of the Company or the Guarantor or any

Obligations; or any sale, lease or transfer of any or all of the assets of the
Company or the Guarantor, or any changes in the shareholders of the Company or
the Guarantor;

         (d) Invalidity of Obligations. The invalidity, illegality or
unenforceability of all or any part of the Obligations or any Loan Document,
including the Notes, for any reason whatsoever, including without limitation
the fact that the Obligations, or any part thereof, exceed the amount permitted
by law, the act of creating the Obligations or any part thereof is ultra vires,
the officers or representatives executing any Loan Document or otherwise
creating the Obligations acted in excess of their authority, the Obligations
violate applicable usury laws, the Company has valid defenses, claims or
offsets (whether at law, in equity or by agreement) which render the
Obligations wholly or partially uncollectible from the Company, the creation,
performance or repayment of the Obligations (or the execution, delivery and
performance of any Loan Document) is illegal, uncollectible, legally impossible
or unenforceable, or the Credit Agreement, the Notes or other Loan Documents
have been forged or otherwise are irregular or not genuine or authentic;

         (e) Release of Obligors. Any full or partial release of the obligation
of the Company on the Obligations or any part thereof, of any co-guarantors, or
any other Person now or hereafter liable, whether directly or indirectly,
jointly, severally, or jointly and severally, to pay, perform, guarantee or
assure the payment of the Obligations or any part thereof, it being recognized,
acknowledged and agreed by the Guarantor that the Guarantor may be required to
pay the Obligations in full without assistance or support of any other Person,
and the Guarantor has not been induced to enter into this Guaranty Agreement on
the basis of a contemplation, belief, understanding or agreement that other
parties other than the Company will be liable to perform the Obligations, or
that the Agents and the Lenders will look to other parties to perform the
Obligations;

         (f) Security. The taking or accepting of any security, collateral or
guaranty, or other assurance of payment, for all or any part of the
Obligations;

         (g) Release of Collateral, etc. Any release, surrender, exchange,

         (h) Care and Diligence. The failure of any Agent or any Lender or any
other Person to exercise diligence or reasonable care in the preservation,
protection, enforcement, sale or other handling or treatment of all or any part
of such collateral, Property or security;

         (i) Status of Liens. The fact that any collateral, security or Lien
contemplated or intended to be given, created or granted as security for the
repayment of the Obligations shall not be properly perfected or created, or
shall prove to be unenforceable or subordinate to any other Lien, it being
recognized and agreed by the Guarantor that the Guarantor is not entering into
this Guaranty Agreement in reliance on, or in contemplation of the benefits of,
the validity, enforceability, collectability or value of any of the collateral
for the Obligations;

         (j) Payments Rescinded. Any payment by the Company to any Agent or
Lender is held to constitute a preference under the bankruptcy laws, or for any
reason an Agent or Lender is required to refund such payment or pay such amount
to the Company or someone else; or

         (k) Other Actions Taken or Omitted. Any other action taken or omitted
to be taken with respect to the Credit Agreement or the other Loan Documents,
the Obligations, or the security and collateral therefor, whether or not such
action or omission prejudices the Guarantor or increases the likelihood that
the Guarantor will be required to pay the Obligations pursuant to the terms
hereof; it being the unambiguous and unequivocal



                                       4
<PAGE>   7
intention of the Guarantor that the Guarantor shall be obligated to pay the
Obligations when due, notwithstanding any occurrence, circumstance, event,
action, or omission whatsoever, whether contemplated or uncontemplated, and
whether or not otherwise or particularly described herein, except for the full
and final payment and satisfaction of the Obligations.

         SECTION 2.09 LIMITATIONS ON OBLIGATION OF THE GUARANTOR HEREUNDER. The
parties hereto (i) intend that the obligation of the Guarantor hereunder be
limited to the maximum amount that would not result in the obligation created
hereby being avoidable under Section 548 of the Federal Bankruptcy Code (11
U.S.C. Section 548; hereinafter "Section 548") or other applicable state
fraudulent conveyance or transfer law and (ii) agree that this Guaranty
Agreement shall be so construed. Accordingly, the obligation of the Guarantor
hereunder is limited to an amount that is the greater of (x) the "reasonably
equivalent value" or "fair consideration" received by the Guarantor in exchange
for the obligation incurred hereunder, within the meaning of Section 548, as
amended, or any applicable state fraudulent conveyance or transfer law, as
amended; or (y) the lesser of (1) the maximum amount that will not render the
Guarantor insolvent or (2) the maximum amount that will not leave the Guarantor
with any Property deemed an unreasonably small capital. Clauses (1) and (2) are
and shall be determined pursuant to Section 548, as amended, or other applicable
state fraudulent conveyance or transfer law, as amended.

         SECTION 2.10 SUBROGATION. The Guarantor shall not exercise any rights
which it may acquire by way of subrogation, reimbursement, exoneration,
indemnification or participation, by any payment made under this Guaranty
Agreement, under any other Loan Document or otherwise until the Obligations have
been paid in full and the Aggregate Commitments are terminated; provided that,
notwithstanding the foregoing, the Guarantor reserves its rights of contribution
and reimbursement, if any, from its co-guarantors, if any, and other Persons
liable on the Obligations or otherwise. Except as described in this Section
2.10, the Guarantor further waives any benefit of any right to participate in
any security now or hereafter held by the Agents and/or the Lenders.

                                  ARTICLE III
                   REPRESENTATIONS, WARRANTIES AND COVENANTS

         SECTION 3.01 REPRESENTATIONS AND WARRANTIES. In order to induce the
Agents and the Lenders to accept this Guaranty Agreement, the Guarantor

warranties will survive the creation of the Obligations and any extension of
credit thereunder) that:

         (a) Benefit to the Guarantor. The Guarantor is a wholly-owned
Subsidiary of the Company and the Guarantor's guaranty pursuant to this Guaranty
Agreement reasonably may be expected to benefit, directly or indirectly, the
Guarantor; and the Guarantor has determined that this Guaranty Agreement is

now being conducted; and (iii) is qualified to do business in all jurisdictions
in which the nature of the business conducted by it makes such qualification
necessary and where failure so to qualify would have a Material Adverse Effect.

                                        5
<PAGE>   8

         (c) No Breach. The execution and delivery by the Guarantor of this
Guaranty Agreement and the other Loan Documents to which it is a party, the
consummation of the transactions herein or therein contemplated, and the
compliance with the terms and provisions hereof will not (i) conflict with or
result in a breach of, or require any consent under (A) the charter or by-laws
of the Guarantor, or (B) any applicable law or regulation, or any order, writ,
injunction or decree of any court or other Governmental Authority, or any
material agreement or instrument to which the Guarantor is a party or by which
it is bound or to which it is subject in each case in such manner as could
reasonably be expected to have a Material Adverse Effect; or (ii) constitute a
default under any such agreement or instrument, or result in the creation or
imposition of any Lien upon any of the revenues or Property of the Guarantor in
each case in such manner as could reasonably be expected to have a Material
Adverse Effect.

         (d) Corporate Action. The Guarantor has all necessary corporate power
and authority to execute, deliver and perform its obligations under this
Guaranty Agreement and the Loan Documents to which it is a party; and the
execution, delivery and performance by the Guarantor of this Guaranty Agreement
and the other Loan Documents to which such Person is a party have been duly
authorized by all necessary corporate action on its part. This Guaranty
Agreement and the Loan Documents to which the Guarantor is a party constitute
the legal, valid and binding obligation of the Guarantor, enforceable against
the Guarantor in accordance with their terms, except as may be limited by
applicable bankruptcy, insolvency, reorganization or other similar laws
affecting creditors' rights and general principals of equity.

         (e) Approvals. Other than consents heretofore obtained or described in
the Credit Agreement, no authorizations, approvals or consents of, and no
filings or registrations with, any Governmental Authority are necessary for the
execution, delivery or performance by the Guarantor of this Guaranty Agreement
or the Loan Documents to which it is a party or for the validity or
enforceability thereof. It is understood that continued performance by the
Guarantor of this Guaranty Agreement and the other Loan Documents to which it is
a party will require various filings, such as filings related to environmental
matters, ERISA matters, Taxes and intellectual property, filings required to
maintain corporate and similar standing and existence, filings pursuant to the
Uniform Commercial Code and other security filings and recordings and filings
required by the SEC, routine filings in the ordinary course of business, and
filings required in connection with the exercise by the Lenders and the Agents
of remedies in connection with the Loan Documents.

         (f) Solvency. The Guarantor (i) is not insolvent and will not be
rendered insolvent as a result of this Guaranty Agreement, (ii) is not engaged
in a business or a transaction, or about to engage in a business or a
transaction, for which any Property or assets remaining with the Guarantor are
unreasonably small capital, and (iii) does not intend to incur, or believe it
will incur, debts that will be beyond its ability to pay as such debts mature.

         (g) No Representation by Agents or Lenders. Neither any Agent, any
Lender nor any other Person has made any representation, warranty or statement
to the Guarantor in order to induce the Guarantor to execute this Guaranty
Agreement.

         SECTION 3.02 COVENANTS. The Guarantor acknowledges that it is has read
the Credit Agreement and hereby covenants and agrees to comply with covenants
and agreements set forth therein which restrict Restricted Subsidiaries of the

                                   ARTICLE IV
                         SUBORDINATION OF INDEBTEDNESS

         SECTION 4.01 SUBORDINATION OF ALL GUARANTOR CLAIMS. As used herein, the
term "Guarantor Claims" shall mean all debts and obligations of the Company to
the Guarantor, whether such debts and obligations now exist or are hereafter
incurred or arise, or whether the obligation be direct, contingent, primary,
secondary, several, joint and several, or otherwise, and irrespective of whether
such debts or obligations be evidenced by note, contract, open account, or
otherwise, and irrespective of the Person or Persons in whose favor such debts
or obligations may, at their inception, have been, or may hereafter be created,
or the manner in which they have been or may hereafter be acquired by the
Guarantor. Except for payments permitted by the Credit Agreement, until the
Obligations shall be paid and satisfied in full, the Aggregate Commitments are
terminated and the Guarantor shall have performed all of its obligations
hereunder and the Loan Documents to which it is a party, the Guarantor shall not
receive or collect, directly or indirectly, from the Company any amount upon the
Guarantor Claims.

         SECTION 4.02 CLAIMS IN BANKRUPTCY. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor's relief, or other insolvency
proceedings involving the Company, the Administrative Agent on behalf of the
Agents and the Lenders shall have the right to prove their claim in any
proceeding, so as to establish their rights hereunder and receive directly from
the receiver, trustee or other court custodian, dividends and payments which
would otherwise be payable upon Guarantor Claims. The Guarantor hereby assigns
such dividends and payments to the Administrative Agent for the benefit of the
Agents and the Lenders. Should any Agent or Lender receive, for application upon
the Obligations, any such dividend or payment which is otherwise payable to the
Guarantor, and which, as between the Company and the Guarantor, shall constitute
a credit upon the Guarantor Claims, then upon payment in full of the
Obligations, the Guarantor shall become subrogated to the rights of the Agents
and the Lenders to the extent that such payments to the Agents and the Lenders
on the Guarantor Claims have contributed toward the liquidation of the
Obligations, and such subrogation shall be with respect to that proportion of
the Obligations which would have been unpaid if the Agents and the Lenders had
not received dividends or payments upon the Guarantor Claims.

         SECTION 4.03 PAYMENTS HELD IN TRUST. In the event that notwithstanding
Sections 4.01 and 4.02, the Guarantor should receive any funds, payments, claims
or distributions which is prohibited by such Sections, the Guarantor agrees (a)
to hold in trust for the Agents and the Lenders an amount equal to the amount of
all funds, payments, claims or distributions so received, and (b) that it shall
have absolutely no dominion over the amount of such funds, payments, claims or
distributions except to pay them promptly to the Administrative Agent, for the
benefit of the Agents and the Lenders; and the Guarantor covenants promptly to
pay the same to the Administrative Agent.

         SECTION 4.04 LIENS SUBORDINATE. The Guarantor agrees that, until the
Obligations are paid in full and the Aggregate Commitments terminated, any Liens
upon the Company's assets securing payment of the Guarantor Claims shall be and
remain inferior and subordinate to any Liens upon the Company's assets securing
payment of the Obligations, regardless of whether such encumbrances in favor of
the Guarantor, any Agent or Lender presently exist or are hereafter created or
attach. Without the prior written consent of the Administrative Agent, the
Guarantor, during the period in which any of the Obligations are outstanding or
the Aggregate Commitments are in effect, shall not (a) exercise or enforce any
creditor's right it may have against the Company, or (b) foreclose, repossess,
sequester or otherwise take steps or institute any action or proceeding
(judicial or otherwise, including without limitation the commencement of or
joinder in any liquidation, bankruptcy, rearrangement, debtor's relief or
insolvency proceeding) to enforce any Lien, mortgages, deeds of


                                       7
<PAGE>   10

trust, security interest, collateral rights, judgments or other encumbrances on
assets of the Company held by the Guarantor.

         SECTION 4.05 NOTATION OF RECORDS. All promissory notes and, upon the
request of the Administrative Agent, all accounts receivable ledgers or other
evidence of the Guarantor Claims accepted by or held by the Guarantor shall
contain a specific written notice thereon that the indebtedness evidenced
thereby is subordinated under the terms of this Guaranty Agreement.

                                   ARTICLE V
                                 MISCELLANEOUS

         SECTION 5.01 SUCCESSORS AND ASSIGNS. This Guaranty Agreement is and
shall be in every particular available to the successors and assigns of the
Agents and the Lenders and is and shall always be fully binding upon the legal
representatives, successors and assigns of the Guarantor, notwithstanding that
some or all of the monies, the repayment of which this Guaranty Agreement
applies, may be actually advanced after any bankruptcy, receivership,
reorganization or other event affecting either the Company or the Guarantor.

         SECTION 5.02 NOTICES. Any notice or demand to the Guarantor under or in
connection with this Guaranty Agreement may be given and shall conclusively be
deemed and considered to have been given and received in the manner and to the
address of the Guarantor as provided for in Section 12.02 of the Credit
Agreement.

         SECTION 5.03 AUTHORITY OF ADMINISTRATIVE AGENT. The Guarantor
acknowledges that the rights and responsibilities of the Administrative Agent
under this Guaranty Agreement with respect to any action taken by the
Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option, right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Guaranty Agreement shall, as between
the Agents and the Lenders, be governed by the Credit Agreement and by such
other agreements with respect thereto as may exist from time to time among them,
but, as between the Administrative Agent and the Guarantor, the Administrative
Agent shall be conclusively presumed to be acting as agent for the Lenders with
full and valid authority so to act or refrain from acting; and the Guarantor
shall not be under any obligation, or entitlement, to make any inquiry
respecting such authority.

         SECTION 5.04 CONSTRUCTION.

         (a) THIS GUARANTY AGREEMENT (INCLUDING, BUT NOT LIMITED TO, THE

                                THIRD AMENDMENT

                           FOR NONEXECUTIVE EMPLOYEES

     WHEREAS, there is reserved to the Board of Directors of Ocean Energy, Inc. 
in Section 7 of the Ocean Energy, Inc. Long-Term Incentive Plan for 
Nonexecutive Employees (the "Plan") the right to amend the Plan;



     NOW, THEREFORE, as of May 20, 1998, the Plan is hereby amended as follows:

  1. Section 4(a) is amended to read as follows:

     "Shares Available. Subject to adjustment as provided in Section 4(c), the 
     number of Shares with respect to which Awards may be granted under the Plan
     shall be 3,400,000; provided, however, if as of any January 1 the number of
     Shares that are available for Awards under the Plan is less than 3,400,000
     Shares, the maximum number of Shares available for Awards shall be
     increased automatically on such January 1 by the number of Shares necessary
     to equal 3,400,00 Shares available for Awards. If any Shares covered by an
     Award granted under the Plan, or to which such an Award relates, are
     forfeited, or if an Award otherwise terminates or is canceled without the
     delivery of Shares or of other consideration, then the Shares covered by
     such Award, or to which such Award relates, or the number of Shares
     otherwise counted against the aggregate number of Shares with respect to
     which Awards may be granted, to the extent of any such forfeiture,
     termination or cancellation, shall again be, or shall become, Shares with
     respect to which Awards may be granted, but only if, and to the extent
     that, the number of Shares then available for Awards does not exceed
     3,400,000 Shares."

Except as amended by this third Amendment, the Plan shall continue without 
interruption or change.
