COMPANY'S INDEPENDENT PRODUCER FINANCE PROGRAM.

                                  THE COMPANY

     Domain is an independent oil and gas company engaged in the exploration,
development, production and acquisition of domestic oil and natural gas
properties, principally in the Gulf Coast region. The Company complements these
activities with its Independent Producer Finance Program (the "IPF Program")
pursuant to which it invests in oil and natural gas reserves through the
acquisition of term overriding royalty interests. The Company's future growth
will be driven by development, exploitation and exploration drilling on its
existing properties, by the continuation of an opportunistic acquisition
strategy in the Gulf Coast region and by further expansion of the IPF Program.

     The Company was formed in December 1996 by the management of Tenneco
Ventures Corporation and an affiliate of First Reserve Corporation to acquire
(the "Acquisition") Tenneco Ventures Corporation and certain of its affiliates
(collectively, "Tenneco Ventures"). Senior management of the Company
established Tenneco Ventures in 1992 as a separate business unit of its former
parent, Tenneco Inc. ("Tenneco"), to engage in exploration and production, oil
and gas program management, producer finance and related activities. All of the
Company's executive officers are veterans of the Tenneco organization, and 11 of
the Company's 19 technical personnel have Tenneco Oil Company backgrounds.
Approximately 90% of the Company's employees, including all of its management,
have purchased shares of Common Stock in the Company.

     During the last four years, the Company has grown primarily through the
opportunistic acquisition of Gulf of Mexico properties and the subsequent
development, exploitation and exploration of these properties, resulting in
substantial increases in its reserves and production. The Company believes that
its acquisition costs, lease operating costs and net general and administrative
costs on a per Mcfe basis are low relative to other companies operating
principally in the Gulf Coast region. From 1994 through 1996, the Company
completed 11 acquisitions aggregating $106.9 million, with an average cost of
proved reserves estimated at the time of acquisition of $0.48 per Mcfe. Eight of
the 11 acquisitions were Gulf Coast region properties. In 1996 the Company
achieved a lease operating expense of $0.44 per Mcfe of production and a net
general and administrative expense (excluding Tenneco overhead allocations) of
$0.12 per Mcfe of production.

     The Company's pro forma estimated net proved reserves as of December 31,
1996 were 153.8 Bcfe, and its pro forma average daily production during 1996 was
85.6 MMcfe, each of which represents a twelvefold increase from levels in 1993.
Approximately 60% of these reserves were natural gas, and approximately 67% of
proved reserves were classified as proved developed producing. On a pro forma
basis

                                       3
<PAGE>
as of December 31, 1996, the Company had a PV-10 Reserve Value of $213.0
million, which does not include reserve value attributable to the IPF Program.

     Through the IPF Program, the Company complements its exploration and
production activities by providing capital to independent producers in return
for term overriding royalty interests in oil and gas properties owned by such
producers. From inception through December 31, 1996, the IPF Program has
generated an average return on net assets in excess of 20%. In addition, the
Company believes that the IPF Program offers a lower level of reserve,
production and price risk than that associated with working interest ownership.
From inception through December 31, 1996, the Company completed 40 transactions
under its IPF Program. At December 31, 1996, based on Company estimates and
assuming prices of $2.10 per Mcf of natural gas and $21.00 per Bbl of oil, the
net present value attributable to IPF Program assets was $25.0 million.

     The Company generated earnings before interest, taxes and depreciation and
amortization ("EBITDA") plus IPF Program return of capital of $41.6 million in
1996, $27.6 million in 1995 and $8.7 million in 1994. IPF Program return of
capital was $4.6 million in 1996, $2.6 million in 1995 and $3.5 million in 1994.
The Company's 1996 pro forma EBITDA plus IPF Program return of capital was $59.2
million.

     The Company's Board of Directors has authorized a capital budget of $125.0
million for 1997. These planned expenditures consist of $23.0 million for
development and exploitation expenditures on the Company's existing Gulf Coast
region properties, $6.0 million for exploratory drilling, $36.0 million for IPF
Program investments and $60.0 million for acquisitions in the Company's core
operating area, $30.0 million of which is pending. See " -- Pending
Transactions -- The Funds Acquisition."

BUSINESS STRATEGY

     The Company's objective is to maximize shareholder value by growing
reserves, production, cash flow and earnings through the opportunistic
acquisition of Gulf Coast region properties with underexploited value. The
Company applies 3-D seismic and other advanced technologies to development,
exploitation and exploration. These activities are complemented by the continued
expansion of the IPF Program. Fundamental to the execution of the Company's
strategy is its foundation of experienced technical talent strengthened by a
high level of financial, transactional and risk-management expertise resulting,
in part, from the former association of the Company and its employees with
Tenneco.

     GEOGRAPHIC FOCUS.  The Company concentrates its primary oil and gas
activities in the Gulf Coast region, specifically in state and federal waters
off the coast of Texas and Louisiana. The Company believes this region remains
attractive for future development, exploration and acquisition activities. This
is due to the availability of seismic data, significant reserve potential and a
well developed infrastructure of gathering systems, pipelines and platforms with
ready access to drilling services and equipment in the region. In addition, the
Company's relationships with major oil companies and independent producers
operating in the region allow continued access to new opportunities. This
geographic focus has enabled the Company to build and utilize a base of
region-specific geological, geophysical, engineering and production expertise.
The Company's geographic focus allows it to manage a large asset base with
relatively few employees, thus permitting the Company to control expenses and
add Gulf of Mexico production at a relatively low incremental cost.

     ACQUISITION OF PROPERTIES WITH UNDEREXPLOITED VALUE.  The Company employs
an acquisition strategy targeted primarily at purchases of Gulf Coast region
producing properties from major oil companies and large independents. These
properties provide opportunities to increase reserves, production and cash flow
through development and exploitation drilling and lease operating expense
reduction. The Company manages its acquired properties by working proactively
with its joint interest partners to accelerate development, identify
exploitation opportunities and implement cost controls on these properties.

                                       4
<PAGE>
     DEVELOPMENT, EXPLOITATION AND EXPLORATION.  The Company integrates its
reservoir and production engineering expertise with its geologic and seismic
interpretation abilities to enhance the results of its exploration and
production business. The Company applies workovers, recompletions, secondary
recovery operations and other production enhancement techniques on its existing
properties to increase recoverable reserves, production and cash flow.
Additionally, the Company uses advanced technology in both its development and
exploration activities to reduce drilling risks and finding costs and to
prioritize its drilling prospects based on return potential. The Company's
ability to obtain 3-D seismic data and its balanced integration of reservoir and
production engineering with such data allows it to identify multiple development
and exploratory prospects in mature producing fields that were not identified
through earlier technologies. The Company currently employs six geoscientists
with an average experience level of more than 16 years and operates two
geophysical workstations interpreting 3-D seismic data over twelve fields and
six exploratory programs. The Company intends to expand its geoscience team in
1997.

     The Company has assembled a multiyear inventory of development,
exploitation and exploratory drilling opportunities in the Gulf Coast region and
has identified more than 70 drilling and recompletion opportunities for 1997.
Most of the properties comprising this inventory are located in fields that have
well-established production histories. The Company believes these properties may
yield significant additional recoverable reserves through the application of
advanced exploration and development technologies. The Company participated in
the drilling of nine development wells and 33 exploratory wells in 1996, of
which 78% and 61%, respectively, were successful.

     CONTINUED EXPANSION OF THE IPF PROGRAM.  The Company has leveraged its
expertise in oil and gas reserve appraisal and evaluation to develop and grow
the IPF Program. The Company believes this program offers an attractive
risk/reward balance and stable earnings. The oil and gas companies that
establish a relationship with the Company through the IPF Program often come to
view the Company as a prospective working interest partner for their drilling or
acquisition projects. Management believes that the investment opportunities,
market information and business relationships generated as a result of the IPF
Program provide the Company with a strategic advantage over other independent
oil and gas companies that are not engaged in this business. As a result of the
Company's efficiency in originating and closing IPF Program transactions in the
$0.5 to $5.0 million range, the Company currently encounters only limited
competition from alternate sources of capital for investment in quality
properties and projects of independent oil and gas companies.

     The Company closed six IPF Program transactions in the first quarter of
1997 for an aggregate of $9.1 million. In addition, the Company is currently
evaluating over 30 transactions, all of which satisfy the Company's initial
screening criteria. The Company has budgeted $36.0 million for investment in IPF
Program transactions in 1997.

PENDING TRANSACTIONS

     THE FUNDS ACQUISITION.  The Company previously sponsored and managed two
oil and gas investment programs (collectively, the "Funds") for institutional
investors. The Company has reached an agreement with the investors in the Funds
to acquire certain property interests from such investors upon consummation of
the Offering (the "Funds Acquisition"). These property interests are primarily
located in the Gulf Coast region and have combined proved reserves of 33.0 Bcfe.
Furthermore, these interests include 17,821 net undeveloped leasehold acres with
3-D seismic-based exploration potential. The Company expects to acquire these
property interests at an aggregate cost of $30.0 million, effective January 1,
1997, for a unit cost of $0.65 per Mcfe of net proved reserves. The Funds
Acquisition will provide the Company with a larger interest in certain of its
existing properties, including the West Delta 30 Field in the Gulf of Mexico.

     THE MICHIGAN DISPOSITION.  The Company has substantially completed
negotiations and expects to close the sale of its interests in a natural gas
development project located in northwestern Michigan (the

                                       5
<PAGE>
"Michigan Development Project") in the near future. The Company views this
transaction (the "Michigan Disposition") as a disposition of non-core assets
and a further enhancement of its focus on the Gulf Coast region. The aggregate
sales price including assumption of debt is expected to be $32.2 million net to
the Company's interest. Upon consummation of the transaction, the Company will
sell 28.8 Bcfe of proved reserves as of December 31, 1996 (of which 3.3 Bcfe
were proved developed producing as of December 31, 1996) and interests in a
pipeline company and a processing company.

DEVELOPMENT, EXPLOITATION AND EXPLORATION PROJECTS

     RABBIT ISLAND FIELD.  In 1993 the Company purchased a 25% interest in the
Rabbit Island Field located in Louisiana state waters. The field has produced in
excess of 1.2 Tcf of gas and 46 MMBbls of oil. A 105 square-mile 3-D survey was
interpreted in 1993, and six of seven wells drilled since that time have been
successful, discovering 34.3 Bcfe of gross proved reserves (7.2 Bcfe net to the
Company's interest). The Company, Texaco Exploration and Production Inc.
("Texaco") and Shell Offshore Inc. ("Shell") are conducting a joint field
study to delineate additional exploitation opportunities in this field. This
study is expected to be completed in the third quarter of 1997. The preliminary
results of the study indicate at least 25 potential exploitation opportunities.

     WEST DELTA 30.  In 1995 the Company purchased a 70% working interest in the
West Delta 30 Field in the Gulf of Mexico from Shell and initiated an integrated
geological, geophysical and 3-D seismic study in the first half of 1996. As a
result of this study, the Company identified eight additional development
drilling locations and three deeper pool prospects that the Company believes
have significant exploratory potential. Based on the Company's proposal, Exxon
Company, U.S.A. ("Exxon"), the operator, has committed to drill a well to test
this field's deeper exploratory potential in mid-year 1997 and a development
well by year-end 1997.

     MATAGORDA ISLAND 519.  In late 1994 the Company purchased 13 producing
fields in the Gulf of Mexico from Pennzoil Company ("Pennzoil") for $51.3
million (the "Pennzoil Acquisition"), including the Matagorda Island 519
Field. The Company owns working interests of 17% and 25% in this field, which is
operated by Amoco Production Company ("Amoco"). Workover operations on three
wells in this field are scheduled to be performed in 1997. Amoco completed such
operations on the first well in January 1997, increasing gross production by 10
MMcf per day, a 50% increase in production attributable to the well. The Company
believes that significant development and exploratory potential remains in the
field. Amoco has purchased a 3-D seismic survey to delineate these
opportunities, in which the Company owns a 25% working interest.

     HIGH ISLAND 110/111.  The Company purchased its initial interest in this
Texaco-operated field as part of the Pennzoil Acquisition and currently holds a
17% working interest. The Company has identified several recompletion zones and
two proved undeveloped drilling locations in the field using 3-D seismic data to
reinterpret an internal field study. These wells are scheduled to be drilled in
1997.

     MUSTANG ISLAND 846/847.  The Company operates and owns a 100% working
interest in this field, which it acquired as part of the Pennzoil Acquisition.
Although the field was previously not producing and scheduled for abandonment by
Pennzoil, the Company initiated a three-well recompletion program on the field
shortly after its acquisition resulting in production of 8.8 MMcf per day. The
Company has conducted a detailed field study and identified a development
location that the Company believes has significant reserve potential. The
Company plans to drill this location by mid-year 1997.

     WASSON FIELD.  In June 1996 the Company acquired a 34.7% working interest
in the Cornell Unit in the Wasson Field in West Texas. Approximately 1.5 billion
Bbls of oil have been produced from the San Andres reservoir from which the
Cornell Unit produces. The field was initially waterflooded in 1965, and a CO2
flood was initiated in 1985 utilizing the water alternating-gas injection method
of enhanced oil recovery. Because the field has been restored to its original
pressure as the result of tertiary recovery activities, at year-end 1996 the
Company recommended the cessation of CO2 purchases for the next four to

                                       6

five years. This recommendation was adopted by the unit working interest owners.
As a result, the Company expects to increase its annual cash flow from the field
by $1.9 million. The Company, working with unit operator Exxon, has identified
up to 30 infill drilling locations. Furthermore, pressure tests performed
recently in an adjoining unit indicate that the upper gas-bearing sands may be
produced separately from the oil reservoir. Exxon and the Company plan to test
the feasibility of producing these gas-bearing sands in 1997.

- ------------
(1) IPF Activities includes income from the Company's IPF Program and the
    Company's "GasFund" partnership with a financial investor. See "Business
    and Properties -- Producer Investment Activities."
(2) Net income per share has been computed based on the net income shown above
    and assuming that the 7,177,682 shares of Common Stock purchased in
    connection with the Acquisition, the 486,013 shares of Common Stock
    purchased by the Company's employees in 1997, the 849,702 shares of Common
    Stock reserved for issuance pursuant to outstanding options under the Stock
    Purchase and Option Plan, and the 6,000,000 shares of Common Stock to be
    issued in connection with the Offering were outstanding since January 1,
    1996.
(3) EBITDA represents earnings before interest expense, income taxes,
    depreciation, depletion and amortization. The Company believes that EBITDA
    may provide additional information about the Company's ability to meet its
    future requirements for debt service, capital expenditures and working
    capital. EBITDA is a financial measure commonly used in the oil and gas
    industry and should not be considered in isolation or as a substitute for
    net income, operating income, net cash provided by operating activities or
    any other measure of financial performance presented in accordance with
    generally accepted accounting principles or as a measure of a company's
    profitability or liquidity. Because EBITDA excludes some, but not all, items
    that affect net income and may vary among companies, the EBITDA calculation
    presented above may not be comparable to similarly titled measures of other
    companies.
(4) To more accurately reflect the actual cash flow generated by the Company,
    IPF Program return of capital is identified separately to allow such cash
    receipts to be combined with EBITDA.

ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE PURCHASING
THE SHARES OF COMMON STOCK OFFERED HEREBY.

VOLATILITY OF OIL AND NATURAL GAS PRICES; MARKETABILITY OF PRODUCTION

     The Company's financial condition, profitability, future rate of growth and
ability to borrow funds or obtain additional capital, as well as the carrying
value of its oil and natural gas properties, are substantially dependent upon
prevailing prices of, and demand for, oil and natural gas. The energy markets
have historically been, and are likely to continue to be, volatile, and prices
for oil and natural gas are subject to large fluctuations in response to
relatively minor changes in the supply and demand for oil and natural gas,
market uncertainty and a variety of additional factors beyond the control of the
Company. These factors include the level of consumer product demand, weather
conditions, the actions of the Organization of Petroleum Exporting Countries,
domestic and foreign governmental regulations, political stability in the Middle
East and other petroleum producing areas, the foreign and domestic supply of oil
and natural gas, the price of foreign imports, the price and availability of
alternative fuels and overall economic conditions. A substantial or extended
decline in oil or natural gas prices could have a material adverse effect on the
Company's financial position, results of operations, quantities of oil and
natural gas reserves that may be economically produced, carrying value of its
proved reserves, borrowing capacity and access to capital. In addition, the
marketability of the Company's production depends upon a number of factors
beyond the Company's control, including the availability and capacity of
transportation and processing facilities, the effect of federal and state
regulation of oil and natural gas production and transportation, changes in
supply due to drilling by other producers and changes in demand. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

RISK OF HEDGING ACTIVITIES

     The Company's use of energy swap arrangements to reduce its sensitivity to
oil and natural gas price volatility is subject to a number of risks. If the
Company's reserves are not produced at the rates estimated by the Company due to
inaccuracies in the reserve estimation process, operational difficulties or
regulatory limitations, or otherwise, the Company would be required to satisfy
its obligations under potentially unfavorable terms. If the Company enters into
financial instrument contracts for the purpose of hedging prices and the
estimated production volumes are less than the amount covered by these
contracts, the Company would be required to mark-to-market these contracts and
recognize any and all losses within the determination period. Further, under
financial instrument contracts the Company may be at risk for basis
differential, which is the difference in the quoted financial price for contract
settlement and the actual physical point of delivery price. The Company will
from time to time attempt to mitigate basis differential risk by entering into
basis swap contracts. Substantial variations between the assumptions and
estimates used by the Company in its hedging activities and actual results
experienced could materially adversely affect the Company's anticipated profit
margins and its ability to manage risk associated with fluctuations in

                                       11
<PAGE>
oil and natural gas prices. Furthermore, the fixed price sales and hedging
contracts limit the benefits the Company will realize if actual prices rise
above the contract prices.

     As of March 15, 1997, on a pro forma basis, approximately 34.0% of the
Company's projected 1997 oil production and approximately 41.7% of its projected
1997 natural gas production were committed to hedging contracts. In addition,
the Company has hedges in place covering a portion of its projected oil
production through the year 2000. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Other Matters -- Hedging
Activities."

RESERVE REPLACEMENT RISKS

     The Company's future performance is dependent upon its ability to identify,
acquire and develop additional oil and natural gas reserves that are
economically recoverable. Without successful drilling or acquisition activities,
the Company's reserves and revenues will decline. No assurances can be given
that the Company will be able to identify, acquire or develop additional
reserves at an acceptable cost.

     The successful acquisition of producing properties requires an assessment
of recoverable reserves, future oil and natural gas prices, operating costs,
potential environmental and other liabilities and other factors beyond the
Company's control. This assessment is necessarily inexact and its accuracy is
inherently uncertain. In connection with such an assessment, the Company
typically performs, or retains a third party to perform, a review of the subject
properties, which review the Company believes is generally consistent with
industry practices. This review, however, will not reveal all existing or
potential problems, nor will it permit the Company to become sufficiently
familiar with the properties to assess fully their deficiencies and
capabilities. Inspections may not be performed on every well, and structural and
environmental problems are not necessarily observable even when an inspection is
undertaken. The Company generally assumes preclosing liabilities, including
environmental liabilities, in connection with property acquisitions and
generally acquires interests in the properties on an "as is" basis. With
respect to its acquisitions to date, the Company has no material commitments for
capital expenditures to comply with existing environmental requirements. There
can be no assurance that any properties acquired by the Company will be
successfully developed or produced, and any such properties that are not
successfully developed or produced could have a material adverse effect on the
Company.

     Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered. There can be no
assurance that any 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. In addition, the Company's
use of 3-D seismic requires greater pre-drilling expenditures than traditional
drilling strategies. 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 economic conditions, mechanical problems, title
problems, weather conditions, compliance with governmental requirements and
shortages or delays in the delivery of equipment and services. There can be no
assurances that any of the Company's future drilling activities will be
successful, and unsuccessful drilling activities by the Company may have a
material adverse effect on the Company. See "Business and
Properties -- Operating Hazards and Drilling Risks."

NON-OPERATOR STATUS

     With the exception of the Mustang Island 846/847 Field and the Company's
interests in Michigan, all of the Company's oil and gas properties are operated
by others. As a result, the Company has a limited ability to exercise control
over operations or the associated costs of such operations. The success of the
Company's investment in a drilling or acquisition activity is therefore
dependent upon a number of factors that are outside of the Company's control,
including the competence and financial resources of the operator. Such factors
include the availability of future capital resources of the other participants
for the drilling of wells and the approval of other participants of the drilling
of wells on the properties in which the Company has an interest. The Company's
reliance on the operator and other working interest owners and its limited

                                       12
<PAGE>
ability to control certain costs could have a material adverse effect on the
realization of expected rates of return on the Company's investment in drilling
or acquisition activities.

OPERATING RISKS

     The oil and natural gas business involves a variety of operating risks,
including the risk of fire, explosions, blow-outs, pipe failure, abnormally
pressured formations and environmental hazards such as oil spills, gas leaks,
ruptures or discharges of toxic gases. Any of these occurrences could result in
substantial losses to the Company due to injury or loss of life, severe damage
to or destruction of property, natural resources and equipment, pollution or
other environmental damage, clean-up responsibilities, regulatory investigation
and penalties and suspension of operations. Moreover, offshore operations are
subject to a variety of operating risks peculiar to the marine environment,
including hurricanes or other adverse weather conditions, more extensive
governmental regulation (including regulations that may, in certain
circumstances, impose strict liability for pollution damage) and interruption or
termination of operations by governmental authorities based on environmental or
other considerations. The presence of unanticipated pressure or irregularities
in formations, miscalculations or accidents may cause a drilling or production
operation to be unsuccessful, resulting in a total loss of the Company's
investment in such operation. Although the Company maintains insurance coverage
it believes is customary in the industry for companies of similar size, it is
not fully insured against certain of these risks, either because such insurance
is not available or because of the high premium costs. The Company does not
carry business interruption insurance. There can be no assurance that any
insurance obtained by the Company will be adequate to cover any losses or
liabilities, or that such insurance will continue to be available or available
on terms that are acceptable to the Company. See "Business and
Properties -- Operating Hazards and Drilling Risks."

RELIANCE ON ESTIMATES OF OIL AND NATURAL GAS RESERVES

     The reserve data set forth in this Prospectus represent only estimates of
DeGolyer and MacNaughton ("DeGolyer"), Netherland, Sewell & Associates, Inc.
("Netherland, Sewell"), and other third-party petroleum engineers. The
estimation of reserve data is a subjective process of estimating the recovery of
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 the available data, the assumptions made, and engineering and
geological interpretation and judgment. Estimates of economically recoverable
oil and natural gas reserves and future net cash flows therefrom necessarily
depend upon a number of variable factors and assumptions, including historical
production from the area compared with production from other producing areas,
the assumed effects of regulation by governmental agencies and assumptions
concerning future oil and natural gas prices, future operating costs, severance
and excise taxes, development costs and workover and remedial costs, all of
which may in fact vary considerably from actual results. Any such estimates are
therefore inherently imprecise, and estimates by other engineers, or by the same
engineers at a different time, might differ materially from those included
herein. Actual prices, production, development expenditures, operating expenses
and quantities of recoverable oil and natural gas reserves will vary from those
assumed in the estimates, and it is likely that such variances will be
significant. Any significant variance from the assumptions could result in the
actual quantity of the Company's reserves and future net cash flows therefrom
being materially different from the estimates set forth in this Prospectus. In
addition, the Company's estimated reserves may be subject to downward or upward
revision, based upon production history, results of future exploration and
development, prevailing oil and natural gas prices, operating and development
costs and other factors. The Company's properties may also be susceptible to
hydrocarbon drainage from production by other operators on adjacent properties.
See "Business and Properties -- Oil and Natural Gas Reserves."

     The present value of future net cash flows set forth in this Prospectus
should not be construed as the current market value or the value at any prior
date of the estimated oil and natural gas reserves attributable to the Company's
properties. In accordance with applicable requirements of the Securities and
Exchange Commission (the "Commission"), the estimated discounted future net
cash flows from estimated proved reserves are based on prices and costs as of
the date of the estimate unless such prices or costs are

                                       13
<PAGE>
contractually determined at such date. Actual future prices and costs may be
materially higher or lower. Actual future net cash flows also will be affected
by factors such as actual production, supply and demand for oil and natural gas,
curtailments or increases in consumption by natural gas purchasers, changes in
governmental regulations or taxation and the impact of inflation on costs. In
addition, the 10% discount factor used to calculate the present value of future
net cash flows is not necessarily the most appropriate discount factor based on
interest rates in effect from time to time and risks associated with the Company
or the oil and gas industry in general.

CERTAIN RISKS AFFECTING THE COMPANY'S IPF PROGRAM

     The Company's IPF Program involves an up-front cash payment for the
purchase of a term overriding royalty interest pursuant to which the Company
receives an agreed upon share of revenues from identified properties. The
producer's obligation to deliver such revenues is nonrecourse to the producer
insofar as the producer generally is not liable to the Company for any failure
to meet its payment obligation except for such failures attributable to the
producer's failure to operate prudently, title failure or certain other causes
within the control of the producer. Consequently, the Company's ability to
realize successful investments through its producer finance business is subject
to the Company's ability to estimate accurately the volumes of recoverable
reserves from which the applicable production payment is to be discharged and
the operator's ability to recover these reserves. The Company's interest is
believed to constitute a property interest and, therefore, in the event of the
producer's bankruptcy or similar event, outside of the reach of the producer's
creditors; however, such creditor (or the producer as debtor-in-possession or a
trustee for the producer in a bankruptcy proceeding) may argue that the
transaction should be characterized as a loan, in which case the Company may
have only a creditor's claim for repayment of the amounts advanced. As non-
operating interests, the Company's ownership of these production payments should
not expose the Company to liability attendant to the ownership of direct working
interests, such as environmental liabilities and liabilities for personal injury
or death or damage to the property of others, although no assurances can be made
in this regard. Finally, as the producer's obligation is only to deliver a
specified share of revenues, subject to the ability of the burdened reserves to
produce such revenues, the Company bears the risk that future revenues delivered
will be insufficient to amortize the purchase price paid by the Company for the
interest or to provide any investment return thereon.

     The Company operates the IPF Program through its indirect wholly-owned
subsidiary, Domain Energy Finance Corporation ("IPF Company"). IPF Company has
a $20.0 million revolving credit facility with a bank (the "IPF Company Credit
Facility") pursuant to which it finances a portion of the IPF Program. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources -- IPF Company Credit Facility."

EFFECTS OF LEVERAGE

     On a pro forma basis as of December 31, 1996, the Company would have had
total consolidated indebtedness for money borrowed of approximately $25.3
million (including approximately $19.1 million outstanding under the Company's
revolving credit facility with a group of banks (the "Revolving Credit
Facility") and approximately $6.2 million outstanding under the IPF Company
Credit Facility) and stockholders' equity of approximately $106.2 million. The
Company intends to incur additional indebtedness for money borrowed in the
future, including in connection with the exploration for, and development,
production and acquisition of, oil and natural gas properties. These activities
could cause the Company's leverage to increase, which could have important
consequences to its stockholders, including the following: (i) the Company's
ability to obtain additional financing for working capital, capital
expenditures, acquisitions or general corporate purposes could be impaired in
the future; (ii) a substantial portion of the Company's cash flow from
operations could be required for the payment of principal and interest on its
indebtedness for money borrowed, thereby reducing the funds available to the
Company for its operations and other purposes; (iii) the Company may be
substantially more leveraged than certain of its competitors, which could place
the Company at a competitive disadvantage; and (iv) the Company's substantial
degree of leverage could hinder its ability to adjust rapidly to changing market
conditions and could make it more

                                       14
<PAGE>
vulnerable in the event of a downturn in general economic conditions or its
business. In addition, the Company's borrowings are and are expected to continue
to be at variable rates, which exposes the Company to the risk of increased
interest rates. See " -- Substantial Capital Requirements" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources -- Revolving Credit Facility."

     The Company's ability to make scheduled payments of principal of and to pay
interest on, or to refinance, its indebtedness for money borrowed depends upon
its future performance and successful strategy implementation, which is subject
not only to its own actions but also to general economic, financial,
competitive, legislative, regulatory and other factors beyond its control, as
well as to the prevailing market prices for oil and natural gas. There can be no
assurance that the Company's business will generate sufficient cash flow from
operations or that future credit will be available in an amount sufficient to
enable the Company to service its indebtedness for money borrowed, or make
necessary capital expenditures. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."

RESTRICTIVE DEBT COVENANTS

     The Revolving Credit Facility contains covenants that, among other things,
restrict the ability of the Company to dispose of assets, incur additional
indebtedness or grant liens on its properties, repay other indebtedness, pay
dividends, enter into certain investments or acquisitions, repurchase or redeem
capital stock, engage in mergers or consolidations, or engage in certain
transactions with subsidiaries and affiliates and that will otherwise restrict
corporate activities. There can be no assurance that such restrictions will not
adversely affect the Company's ability to finance its future operations or
capital needs or engage in other business activities that may be in the
interests of the Company. In addition, the Revolving Credit Facility requires
the Company to maintain a specified minimum tangible net worth and to comply
with certain prescribed financial ratios. The ability of the Company to maintain
such tangible net worth or to comply with such ratios may be affected by events
beyond the Company's control. A breach of any of these covenants or the
inability of the Company to maintain such tangible net worth or to comply with
the required financial ratios could result in a default under the Revolving
Credit Facility. The Company believes that the Company is currently in
compliance with the terms of the Revolving Credit Facility. However, in the
event of any such default, the lenders thereunder (the "Lenders") could elect
to terminate the Company's ability to borrow thereunder, to declare all
borrowings outstanding thereunder, together with accrued interest and other
fees, to be immediately due and payable, and to exercise foreclosure or other
remedies against the Company and its assets. The Revolving Credit Facility is
secured by approximately 80% of the aggregate value of the Company's oil and
natural gas properties and substantially all of the Company's other property
(other than the IPF Program properties), including the capital stock of the
Company's operating subsidiaries. Although the remaining approximately 20% of
the aggregate value of the Company's oil and natural gas properties is not
mortgaged to the Lenders under the Revolving Credit Facility, such properties
are nevertheless subject to the restrictions set forth therein, including a
prohibition on granting any security interests therein. If the indebtedness
under the Revolving Credit Facility were to be accelerated, there can be no
assurance that the assets of the Company would be sufficient to repay such
indebtedness in full. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital
Resources -- Revolving Credit Facility."

     The IPF Company Credit Facility restricts the ability of the IPF Company to
dividend cash to its parent, Domain Energy Ventures Corporation, or otherwise
advance cash to the Company. Consequently, cash generated by the IPF Company may
not be available to the Company, whether for repayment of the Revolving Credit
Facility or for other purposes. The IPF Company Credit Facility is secured by
substantially all of IPF Company's oil and gas interests, including the notes
receivable generated therefrom. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources -- IPF Company Credit Facility."

                                       15

SUBSTANTIAL CAPITAL REQUIREMENTS

     Historically, the Company has financed its activities primarily with
internally generated funds and advances from Tenneco. The Company currently has
plans for substantial capital expenditures to continue its exploration,
development, production and acquisition activities. In 1997, excluding
acquisitions, the Company's budget for capital expenditures and IPF Program
investments is $65.0 million. The Company's business plan is dependent upon the
Company's ability to obtain financing beyond its internally generated cash flow,
for exploring for, developing, producing and acquiring oil and natural gas
properties. Management believes that the Company will have sufficient cash
provided by operating activities and borrowings under the Revolving Credit
Facility to fund planned capital expenditures in 1997. The Revolving Credit
Facility limits the amounts the Company may borrow thereunder to amounts
determined by the Lenders in their sole discretion, based upon the Lenders'
projection of the Company's discounted future net revenues from oil and natural
gas properties and other considerations, and restricts the amounts the Company
may borrow under other credit facilities. The Lenders may periodically adjust
the borrowing base under the Revolving Credit Facility and may require that
outstanding borrowings in excess of the borrowing base be repaid within 30 days
of the date such excess occurs. All amounts owed under the Revolving Credit
Facility are due and payable on December 31, 1999. In addition, the borrowing
base under the Revolving Credit Facility is scheduled to be redetermined as of
December 31, 1997 and may be reduced substantially from its February 28, 1997
level of $63.3 million and all amounts outstanding in excess of such reduced
borrowing base must be paid in full at such date. If revenues or the Company's
borrowing base decrease as a result of lower oil and natural gas prices,
operating difficulties, declines in reserves or otherwise, the Company's ability
to expend the capital necessary to undertake or complete future activities may
be significantly limited. No assurances can be given that the Company will have
adequate funds available to it under the Revolving Credit Facility to carry out
its strategy or that the Company will be able to make any mandatory principal
payments required by the Lenders. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources" and " -- Revolving Credit Facility."

CONTROL BY EXISTING STOCKHOLDERS AND POTENTIAL CONFLICTS OF INTEREST

     Upon completion of the Offering, the Company's existing stockholders will
own approximately 56.1% the outstanding shares of Common Stock (approximately
52.6% if the Underwriter's over-allotment option is exercised in full). First
Reserve Fund VII, Limited Partnership, a Delaware limited partnership ("Fund
VII"), the managing general partner of which is First Reserve Corporation, a
Delaware corporation ("First Reserve"), individually will own approximately
52.5% of the outstanding shares of Common Stock (approximately 49.3% if the
Underwriter's over-allotment option is exercised in full). As a result of such
stock ownership, these stockholders, as a group, and Fund VII, individually,
will be able to elect all members of the Company's board of directors (the
"Board of Directors") and to control the vote on matters submitted to the
Board of Directors or stockholders, including, without limitation, matters
relating to the Company's exploration, development, capital, operating and
acquisition expenditure plans, as well as mergers and other business
combinations, asset sales, financings, issuances of securities and other
significant transactions.

     Such concentration of ownership of Common Stock may have an adverse effect
on the market price of the Common Stock. Conflicts of interest may arise in the
future between the Company and First Reserve and its affiliates with respect to,
among other things, potential competitive business activities or business
opportunities, issuances of additional shares of voting securities, the election
of directors or the payment of dividends, if any, by the Company or the exercise
by First Reserve, as managing general partner of Fund VII, of its ability to
control the management and affairs of the Company. There are no contractual or
other restrictions on the ability of First Reserve or its affiliates to engage
in oil and gas exploration and production or to pursue other investment
opportunities in the energy industry. Circumstances could arise in the future in
which the Company and First Reserve or its affiliates engage in activities in
competition with one another.

                                       16
<PAGE>
DEPENDENCE ON KEY PERSONNEL

     The Company's operations are dependent upon a relatively small group of
management and technical personnel. The loss of one or more of these individuals
could have a material adverse effect on the Company. The Company in particular
is substantially dependent on the efforts of Michael V. Ronca, its President and
Chief Executive Officer. If Mr. Ronca becomes unable or unwilling to continue in
his present role, the Company's business, operations and prospects would be
adversely affected. In connection with the consummation of the acquisition by
the Company of the capital stock of its operating subsidiaries, Mr. Ronca
entered into an Employment Agreement with the Company (the "Ronca Employment
Agreement"). Under the terms of the Ronca Employment Agreement, Mr. Ronca would
be entitled to terminate his employment (i) upon a "Change of Control," which
is defined therein as the acquisition by any person or entity, or group thereof,
excluding Fund VII and other affiliates of First Reserve of more than 50% of the
outstanding voting stock of the Company, or (ii) otherwise for "Good Reason,"
which is defined therein to include, among other things, material reductions in
Mr. Ronca's duties, responsibilities or base salary. See "Management -- Ronca
Employment Agreement."

COMPETITION

     The Company encounters competition from other companies in all areas of its
operations, including the acquisition of producing properties and its IPF
Program. 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 and, in the case of its IPF Program, affiliates
of investment, commercial and merchant banking firms and affiliates of large
interstate pipeline companies. 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 oil and gas business for a much longer time than the
Company. Such companies may be able to pay more for producing 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, as well as its ability to
grow its IPF Program, will be dependent upon its ability to evaluate and select
suitable properties and to consummate transactions in this highly competitive
environment.

GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS

     Oil and natural gas operations are subject to various federal, state and
local governmental laws and regulations that may be changed from time to time in
response to economic, political or other conditions. Matters subject to
regulation include discharge permits for drilling operations, drilling and
abandonment bonds, reports concerning operations, the spacing of wells,
unitization and pooling of properties and taxation. From time to time,
regulatory agencies have imposed price controls and limitations on production by
restricting the rate of flow of oil and natural gas wells below actual
production capacity in order to conserve supplies of such resources. In
addition, the production, handling, storage, transportation and disposal of oil
and natural gas, by-products thereof and other substances and materials produced
or used in connection with oil and natural gas operations are subject to
regulation under federal, state and local laws and regulations primarily
relating to protection of human health and the environment. These laws and
regulations have imposed increasingly strict requirements for water and air
pollution control and solid waste management. To date, the Company's
expenditures related to compliance with these laws and regulations have not been
significant, although no assurances can be given that such expenditures will not
be significant in the future. The Company believes that the trend of more
expansive and stricter environmental legislation and regulations, including
regulations that may be promulgated under the Oil Pollution Act of 1990, will
continue, and that such legislation and regulations may result in additional
costs to the Company in the future. Amendments to the Resource Conservation and
Recovery Act to regulate further the handling, transportation, storage and
disposal of oil and natural gas exploration and production wastes have been
considered by Congress and may be adopted. Such legislation, if enacted, could
have a material adverse impact on the Company's operating costs. See "Business
and Properties -- Regulation."

                                       17

NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE; DILUTION

     Prior to the Offering, there has been no public market for the Common
Stock. The initial public offering price will be determined by negotiations
among the Company, First Reserve, and the Underwriters and may not be indicative
of the future market price for the Common Stock. See "Underwriting" for a
discussion of the factors to be considered in determining the initial public
offering price. Application will be made for approval for listing of the Common
Stock on the New York Stock Exchange. However, no assurance can be made that an
active trading market for the Common Stock will develop or, if developed, that
it will be sustained. The market price of the Common Stock could also be subject
to significant fluctuation in response to variations in results of operations
and other factors. In addition, Fund VII and certain employees of the Company
acquired their shares of Common Stock at a per share price that is substantially
less than the initial public offering price. Investors in the Common Stock
offered hereby will experience immediate and substantial dilution in the net
tangible book value of their shares of Common Stock. At an assumed public
offering price of $14.00 per share, the dilution to new investors would be $6.23
per share. These investors will also experience additional dilution upon the
exercise of outstanding options for the Common Stock. See "Dilution."

SHARES ELIGIBLE FOR FUTURE SALE

     The Company, each of the Company's directors and executive officers and
Fund VII have agreed not to dispose of any shares of Common Stock without the
prior consent of PaineWebber Incorporated for a period of 180 days from the date
of this Prospectus other than pursuant to the Offering or in connection with the
Company's employee benefit plans. The shares of Common Stock held by the
Company's officers and by Fund VII are deemed "restricted securities" within
the meaning of Rule 144 under the Securities Act of 1933, as amended (the
"Securities Act"), and may be resold after the 180-day period only upon
registration under the Securities Act or pursuant to an exemption from
registration, including exemptions contained in Rule 144. Pursuant to the terms
of the Securityholders Agreement, dated as of December 31, 1996, among the
Company, Fund VII and the Company's officers who have subscribed for Common
Stock, upon the consummation of the Offering and after expiration of the 180-day
period referred to above, Fund VII will have the right to demand registration of
its shares of Common Stock. See "Certain Transactions -- Securityholders
Agreement." Fund VII has informed the Company that it has no immediate plans to
sell or otherwise dispose of shares of the Common Stock. As of the date hereof,
options exercisable for 849,702 shares of Common Stock are outstanding under the
Amended and Restated 1996 Stock Purchase and Option Plan for Key Employees of
Domain Energy Corporation and Affiliates (the "Stock Purchase and Option
Plan"). Generally, all shares issued upon the exercise of such options will be
freely tradeable under the Securities Act. Sales of substantial amounts of
Common Stock in the public market, or the perception of the availability of
shares for sale, following the Offering could adversely affect the prevailing
market price of the Common Stock. The Company is unable to make any prediction
as to the effect, if any, that the future sales of Common Stock or the
availability of Common Stock for sale will have on the market price of the
Common Stock prevailing from time to time. See "Shares Eligible for Future
Sale."

BLANK CHECK PREFERRED STOCK

     The Company's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") authorizes "blank check" preferred stock,
which may have the effect of discouraging unsolicited acquisition proposals. See
"Description of Capital Stock -- Preferred Stock."

                                USE OF PROCEEDS

     The net proceeds to the Company of the Offering, calculated at an assumed
initial public offering price of $14.00 per share, are expected to be
approximately $77.1 million ($88.8 million if the Underwriters' over-allotment
option is exercised in full), after deducting underwriting discounts and
commissions and estimated Offering expenses. The Company will use approximately
$30.0 million of the net proceeds to consummate the Funds Acquisition. It is
anticipated that the remainder of the proceeds to the Company of the Offering
will be used to repay $42.1 million of indebtedness outstanding under the
Revolving Credit

                                       18
<PAGE>
Facility and $5.0 million of indebtedness outstanding under the IPF Company
Credit Facility. Pending application of the net proceeds of the Offering, such
net proceeds will be invested in short-term, interest bearing instruments.

     In December 1996, the Company entered into the Revolving Credit Facility
under which the borrowing base was $63.3 million as of February 28, 1997. At
such date, borrowings outstanding under the Revolving Credit Facility totalled
$61.0 million. The initial borrowings under the Revolving Credit Facility were
used to finance a portion of the costs of the Acquisition. The Revolving Credit
Facility is a three-year revolving credit facility with the entire outstanding
principal amount maturing on December 31, 1999. In addition, the borrowing base
under the Revolving Credit Facility is scheduled to be redetermined as of
December 31, 1997 and may be reduced substantially from its current level. All
amounts outstanding in excess of such reduced borrowing base must be paid in
full at such date. Absent a default or an event of default (as defined therein),
outstanding borrowings under the Revolving Credit Facility accrue interest at
LIBOR plus a margin of 1.50% to 2.50% per annum depending on the total amount
drawn or, at the option of the Company, at the greater of (i) the prime rate and
(ii) the federal funds effective rate plus one-half of 1%, plus a margin of
0.50% to 1.50% depending on the total amount drawn. As of February 28, 1997, the
weighted average interest rate applicable to outstanding borrowings under the
Revolving Credit Facility was 8.05% per annum. For a description of the
Revolving Credit Facility, including certain mandatory prepayment terms, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources -- Revolving Credit Facility."

     IPF Company is a party to the IPF Company Credit Facility, which provides
for a maximum $20.0 million revolving line of credit. Borrowings under this
facility are used to finance IPF Company's investment activities under the IPF
Program. The IPF Company Credit Facility matures June 1, 1998 at which time all
amounts owed thereunder are due and payable. The borrowing base under the
facility as of February 28, 1997 was $18.0 million and is subject to a scheduled
redetermination by the lender every six months and such other redeterminations
as the lender may elect to perform each year. As of February 28, 1997,
approximately $11.2 million was outstanding under the IPF Company Credit
Facility and the weighted average interest rate applicable to such outstanding
amount was 7.625% per annum. So long as no default or event of default (as
defined therein) is outstanding, borrowings under the IPF Company Credit
Facility accrue interest at LIBOR plus a margin of 2.25% or, at the option of
IPF Company, the prime rate published in THE WALL STREET JOURNAL. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources -- IPF Company Credit Facility."

                                DIVIDEND POLICY

     The Company intends to retain its earnings to provide funds for
reinvestment in the Company's businesses, including exploration, development and
production activities, and, therefore, does not anticipate declaring or paying
cash dividends in the foreseeable future. The Company is a holding company that
conducts substantially all of its operations through its subsidiaries. As a
result, the Company's ability to pay dividends on the Common Stock would be
dependent on the cash flows of its subsidiaries. Payment of dividends is also
subject to then existing business conditions and the business results, cash
requirements and financial condition of the Company, and will be at the
discretion of the Board of Directors. In addition, the terms of the Revolving
Credit Facility currently prohibit the payment of dividends by the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

                                    DILUTION

     "Dilution" means the difference between the initial public offering price
per share of Common Stock and the pro forma net tangible book value per share of
Common Stock after giving effect to the Offering. "Net tangible book value per
share" represents the amount of total tangible assets less total liabilities
divided by the total number of shares of Common Stock outstanding. At December
31, 1996, after giving effect to the purchase of Common Stock by the Company's
employees in 1997, the Company's pro forma net tangible book value was $29.062
million, or approximately $3.79 per share of Common Stock. Assuming the sale of
6,000,000 shares pursuant to the Offering at a price of $14.00 per share and
assuming the use of the net proceeds thereof as specified in "Use of
Proceeds," the pro forma net tangible book value of the Company at December 31,
1996 would have been $7.77 per share, representing an immediate increase in pro
forma net tangible book value of $3.98 per share to the Company's existing
stockholders and an immediate dilution in pro forma net tangible book value of
$6.23 per share to new investors purchasing shares of Common Stock in the
Offering. The following table illustrates such pro forma per share dilution at
December 31, 1996:

               UNAUDITED CONDENSED PRO FORMA FINANCIAL STATEMENTS

     The unaudited pro forma consolidated balance sheet as of December 31, 1996
gives effect to (i) the sale of shares of Common Stock to the Company's
employees in 1997, (ii) the completion of the Offering and (iii) the completion
of the Funds Acquisition and the Michigan Disposition, as if all such
transactions (the "Transactions") occurred on December 31, 1996. The unaudited
pro forma consolidated income statement for the year ended December 31, 1996
gives effect to (i) the Acquisition and (ii) the completion of the Funds
Acquisition and the Michigan Disposition, as if all such transactions had
occurred on January 1, 1996. The unaudited condensed pro forma balance sheet is
based on the Consolidated Balance Sheet of the Company included elsewhere in
this Prospectus. The unaudited condensed pro forma income statement is based on
the historical Combined Statement of Income of the Company and unaudited
financial information related to the Fund Acquisition.

     The pro forma adjustments are based upon available information and certain
assumptions that management of the Company believes are reasonable. The pro
forma financial information does not purport to represent what the Company's
financial position or results of operations would actually have been had the
Transactions in fact occurred on such dates. In addition, the pro forma
financial statements are not necessarily indicative of the results of future
operations of the Company and should be read in conjunction with
"Capitalization," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," and the Combined and Consolidated
Financial Statements of the Company and the related notes thereto included

               NOTES TO CONDENSED PRO FORMA FINANCIAL STATEMENTS
                                  (UNAUDITED)

BASIS OF PRESENTATION

     The following pro forma adjustments have been prepared as if the
Transactions had taken place on December 31, 1996, in the case of the pro forma
balance sheet or as of January 1, 1996, in the case of the pro forma statement
of income. The adjustments are based upon currently available information and
certain estimates and assumptions, and therefore the actual adjustments made to
effect the Transactions may differ from the pro forma adjustments. However,
management believes that the assumptions provide a reasonable basis for
presenting the significant effects of the Transactions as contemplated and that
the pro forma adjustments give appropriate effect to these assumptions and are
properly applied in the pro forma financial information.

PRO FORMA ADJUSTMENTS TO THE BALANCE SHEET

A.   Reflects the issuance of 486,013 shares of Common Stock at $4.18 per share
     pursuant to two private offerings made to the employees of the Company
     prior to the Offering. For the sale of such shares the Company received
     $1.5 million in cash and notes receivable of $0.6 million. The notes
     receivable have been reflected as a reduction of stockholders' equity. Also
     reflects the effect of the 754-for-one stock split on shares of Common
     Stock issued in connection with the Acquisition.

B.   Reflects (i) the proceeds from the issuance of 6,000,000 shares of Common
     Stock at $14.00 per share pursuant to the Offering and (ii) use of the
     proceeds as summarized below (in millions):

Proceeds from the Offering..............  $    84.0
Offering expenses.......................       (6.9)
                                          ---------
          Net proceeds..................  $    77.1
                                          =========
Use of proceeds:
     Cash for Funds Acquisition.........  $    30.0
     Repayment of long-term debt........       47.1
                                          ---------
          Net proceeds..................  $    77.1
                                          =========

C.   Reflects the pending acquisition of the oil and gas properties of the Funds
     for $30.0 million.

D.   Reflects the pending sale of the Michigan Development Project. After
     repayment by the Company and assumption by the buyer of an aggregate of
     $12.2 million of long-term debt, the Company will receive $1.9 million in
     cash at closing and will receive an additional $5.8 million from the
     payment of an interest-bearing note receivable.

E.   Reflects the repayment of the indebtedness to Fund VII with the proceeds
     from the sale of an $8.0 million certificate of deposit that was released
     as collateral for Domain Energy Guarantor Corporation's guarantee of the
     Michigan Senior Debt as a result of the Michigan Disposition.

PRO FORMA ADJUSTMENTS TO THE INCOME STATEMENT

F.   Reflects the reduction in the depreciation, depletion, and amortization
     rate as a result of the allocation of the Acquisition purchase price in
     accordance with the purchase method of accounting.

G.   Reflects a reduction in general and administrative expenses of $4.8 million
     resulting from the elimination of the components of the corporate overhead
     allocation from Tenneco that were related to severance, retention bonuses,
     and other costs resulting from the merger between Tenneco and an affiliate
     of El Paso Natural Gas Company. In addition, the Company has estimated and
     included $1.0 million of additional costs related to legal, treasury,
     audit, and other services it expects will be incurred by the Company on a
     pro forma basis.

H.   Reflects the adjustments to interest expense computed as follows (in
     thousands):

(1)  The Acquisition financing:
       Revolving Credit Facility........  $   4,896
       IPF Company Credit Facility......        550
       Indebtedness to Fund VII.........        368

                                          ---------
(2)  Repayment of debt using Offering
  proceeds:
       Revolving Credit Facility........     (3,066)
       IPF Company Credit Facility......       (400)    (3,466)
                                          ---------
(3)  Michigan Disposition:
       Michigan Senior Debt.............       (319)
       Repayment of indebtedness to Fund
          VII...........................       (368)      (687)
                                          ---------
(4)  Amounts capitalized -- Funds
  Acquisition...........................       (702)      (702)

       Total pro forma interest expense
          adjustment....................             $    (319)
                                                     =========

    The total pro forma interest expense adjustment reflects a change in the
    interest rate from 8% to 7% for the Revolving Credit Facility due to a
    reduction in the amount of outstanding debt below the borrowing base amount.
    If the interest expense rate increases by 1/8 of 1%, the total pro forma
    interest expense would increase by $31,616.

I.   Reflects the interest income on a certificate of deposit used as collateral
     for the Michigan Development Project.

J.   Reflects the income tax effect of pro forma adjustments computed at an
     estimated effective rate of 38.0%.

K.   Reflects the changes in operating income items from the Michigan
     Disposition.

L.   Reflects change in interest income from:
     (1)  Increase from the note receivable received in the Michigan
          Disposition.
          (2)  Reduction from the Michigan Development Project certificate of
               deposit.

M.  Reflects the changes in operating income items from the Funds Acquisition.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion is intended to assist in understanding the
Company's historical financial position and results of operations as of and for
each year of the three-year period ended December 31, 1996. The Company's
historical financial statements and notes thereto included elsewhere in this
Prospectus contain detailed information that should be referred to in
conjunction with this discussion.

GENERAL

     On December 31, 1996, the Company acquired all of the outstanding capital
stock of its operating subsidiaries, Domain Energy Ventures Corporation
("Ventures Corporation") and Domain Energy Production Corporation
("Production Corporation"). The Company has accounted for the acquisition (the
"Acquisition") using the purchase method of accounting, under which the
purchase price has been allocated to the assets acquired and liabilities assumed
based upon their fair values at the acquisition date.

     The Company is an independent oil and gas company engaged in the
exploration, development, production and acquisition of domestic oil and natural
gas properties, principally in the Gulf Coast region. The Company complements
these activities with its IPF Program pursuant to which it invests in oil and
natural gas reserves through the acquisition of term overriding royalty
interests accounted for as notes receivable. As of December 31, 1996, the
Company had estimated net proved reserves of 149.6 Bcfe. Approximately 60% of
the Company's net proved reserves at such date were natural gas and
approximately 64% of proved reserves were classified as proved developed
producing. As of December 31, 1996, the Company had a PV-10 Reserve Value of
$184.8 million, which does not include reserve value attributable to the IPF
Program.

     The Company's selected historical combined and consolidated financial data
included elsewhere in this Prospectus have been derived from the audited
Combined and Consolidated Financial Statements of the Company. The selected
balance sheet data at December 31, 1996 reflects the Acquisition that occurred
on that date. The selected balance sheet and income statement data at other
dates and for other periods reflects the combined financial position and results
of operations of Ventures Corporation and Production Corporation with
intercompany transactions and account balances eliminated.

     Prior to the Acquisition, these companies and their subsidiaries were
included in the consolidated federal income tax return of Tenneco, as a result
of which Tenneco will receive all benefit for such entities' historical tax
losses. In connection with the Acquisition, the Company agreed to file an
election under Sections 338(g) and 338(h)(10) of the Internal Revenue Code of
1986, as amended, pursuant to which the Company will allocate the purchase price
paid by the Company among the assets of these companies to determine the basis
of assets acquired in accordance with the principles of Treasury Regulation
1.338(h)(10)-1(f)(1)(ii).

(1) In February 1997 the Company paid an additional $500,000 as a post-closing
    adjustment to the Acquisition purchase price.

     The Company's objective is to maximize shareholder value by growing
reserves, production, cash flow and earnings through the opportunistic
acquisition of Gulf Coast region properties with underexploited value. The
Company applies 3-D seismic and other advanced technologies to development,
exploitation and exploration. These activities are complemented by the continued
expansion of the IPF Program. Fundamental to the execution of the Company's
strategy is its foundation of experienced technical talent strengthened by a
high level of financial, transactional and risk-management expertise, resulting
in part, from the former association of the Company and its employees with
Tenneco.

     The Company's revenue, profitability and future rate of growth are
substantially dependent upon prevailing prices for oil and natural gas, which
are dependent upon numerous factors beyond the Company's control, such as
economic, political and regulatory developments and competition from other
sources of energy. The energy markets have historically been highly volatile,
and future decreases in oil or natural gas prices could have a material adverse
effect on the Company's financial position, results of operations, quantities of
oil and natural gas reserves that may be economically produced, and access to
capital.

     The Company uses the full cost method of accounting for its investments in
oil and natural gas properties. Under such methodology, all costs of
exploration, development and acquisition of oil and natural gas reserves are
capitalized into a "full cost pool" as incurred and properties in the pool are
depleted and charged to operations using the unit-of-production method based on
a ratio of current production to total proved oil and natural gas reserves. To
the extent that such capitalized costs (net of accumulated depreciation,
depletion, and amortization) less deferred taxes exceed the present value (using
a 10% discount rate) of estimated future net cash flows from proved oil and
natural gas reserves and the lower of cost or fair value of unproved properties,
such excess costs are charged to operations. If a write-down were required, it
would result in a non-cash charge to earnings but would not have an impact on
cash flows.

ACCOUNTING FOR IPF PROGRAM ACTIVITY

     Through its IPF Program, the Company acquires term overriding royalty
interests in oil and gas properties owned by independent producers. Because the
capital advanced to a producer for these interests is repaid from an agreed upon
share of cash revenues from the sale of production until the capital advanced
plus a contractual return is paid in full, the Company accounts for the term
overriding royalty interests as notes receivable. Under this accounting method,
the Company recognizes only the interest income portion of payments received
from a producer as revenues on its income statement. The remaining cash receipts
are recorded as a reduction in notes receivable on the Company's balance sheet
and as IPF Program return of capital on the Company's statement of cash flows.

                                       29
<PAGE>
     If instead of acquiring dollar-denominated term overriding royalty
interests, the Company were purchasing term overriding royalty interests
requiring delivery of a specified quantity of oil and gas, IPF Program results
would be accounted for differently. Specifically, in 1996, Company EBITDA would
increase by $4.3 million and IPF Program return of capital in the Combined
Statement of Cash Flows would decrease by the same amount. To more accurately
reflect the actual cash flows generated by the Company, IPF Program return of
capital is identified separately to allow such cash receipts to be combined with
EBITDA.

     Although, to date, the Company has not incurred any losses on notes
outstanding under the IPF Program, as of December 31, 1996, the Company
established a non-cash reserve for potential future losses of $437,000.

RESULTS OF OPERATIONS

     The Company has experienced significant growth in reserves, production,
cash flow and earnings over the past three years. The following table summarizes
certain operating and financial data, production volumes, average realized

    EBITDA is a financial measure commonly used in the oil and gas industry and
    should not be considered in isolation or as a substitute for net income,
    operating income, net cash provided by operating activities or any other
    measure of financial performance presented in accordance with generally
    accepted accounting principles or as a measure of a company's profitability
    or liquidity. Because EBITDA excludes some, but not all, items that affect
    net income and may vary among companies, the EBITDA calculation presented

    1995 and 1996 would be $0.23, $0.20 and $0.28, respectively.

  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Oil and natural gas revenues increased from $34.9 million in 1995 to $52.9
million in 1996, an increase of $18.0 million, or 51.6%. Production volumes for
oil and condensate increased from 424 MBbls in 1995 to 574 MBbls in 1996, an
increase of 150 MBbls, or 35.4%. Production volumes for natural gas increased
from 18.1 Bcf in 1995 to 21.5 Bcf in 1996, an increase of 3.4 Bcf, or 19.4%. The
increase in oil and natural gas production was due to new wells being
successfully drilled and completed during 1996, as well as acquisitions of
producing properties. The increase in total net production increased revenues by
$7.6 million. In addition, the Company experienced a 14.0% increase in average
oil and condensate prices and a 27.9% increase in average natural gas prices.
Increases in average oil and natural gas prices were directly attributable to
general improved market conditions.

     As a result of hedging activities, the Company realized an average oil
price of $18.60 per Bbl and an average gas price of $1.96 per Mcf for the year
ended December 31, 1996, compared to average prices of $20.73 per Bbl and $2.40
per Mcf, respectively, that otherwise would have been received. These hedging
activities decreased oil and natural gas revenues by approximately $10.7
million. This loss of revenue was the result of hedges made at the direction of
Tenneco in late 1995.

     Revenues from IPF Activities increased from $2.4 million in 1995 to $4.4
million in 1996, an increase of $2.0 million, or 85.4%. This increase was the
result of a $1.0 million increase in IPF Program revenues and a $1.0 million
increase in GasFund revenues. See "Business and Properties -- Producer
Investment Activities." IPF Program revenues increased as the result of an
increase in IPF Program investments attributable to a 100% increase in IPF
Program customers at year-end 1996 compared to year-end 1995.

     Lease operating expenses increased from $8.0 million in 1995 to $11.0
million in 1996, an increase of $3.0 million, or 37.4%. On an Mcfe basis, lease
operating expenses increased from $0.39 in 1995 to $0.44 in 1996, an increase of
$0.05, or 12.8%. The increase in lease operating expenses was primarily
attributable to increased production volumes. On a per unit basis, the increase
was primarily attributable to the acquisition in June 1996 of an interest in the
Wasson Field, which is undergoing tertiary enhanced recovery and the expenses
associated therewith.

     Depreciation, depletion and amortization ("DD&A") expense remained flat
at $22.7 million from 1995 to 1996. This was the result of higher oil and gas
production volumes partially offset by an 18.5% decrease in the DD&A rate. The
reduced DD&A rate was attributable to the acquisition of low cost reserves in
the Wasson Field and the Company's investment in the Michigan Development
Project. See "Business and Properties -- Pending Transactions -- The Michigan
Disposition."

     General and administrative expense, net of capitalized amounts, increased
from $4.1 million in 1995 to $8.2 million in 1996, an increase of $4.1 million,
or 102.2%. The increase was primarily due to a $3.6 million increase in the
corporate overhead allocation from Tenneco which included costs directly related
to severance payments, retention bonuses and other costs associated with the
merger of Tenneco with an affiliate of El Paso Natural Gas Company and also
reflects that during 1996 the Company was not paid any arrangement fees from
investors in the Funds.

                                       31
<PAGE>
     Income tax expense increased from $0.9 million in 1995 to $5.6 million in
1996, an increase of $4.7 million, or 545%. This was due to an increase in
income before taxes from $2.2 million in 1995 to $13.6 million in 1996 and an
increase in the effective tax rate from 38.9% in 1995 to 40.8% in 1996.

     Net income was $8.2 million in 1996 compared to $1.4 million in 1995, as a
result of the factors described above.

  YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994

     Oil and natural gas revenues increased from $5.3 million in 1994 to $34.9
million in 1995, an increase of $29.6 million, or 553%. Production volumes for
oil and condensate increased from 83 MBbls in 1994 to 424 MBbls in 1995, an
increase of 341 MBbls, or 411%. Production volumes for natural gas increased
from 2.3 Bcf in 1994 to 18.1 Bcf in 1995, an increase of 15.8 Bcf, or 674%. The
increase in oil and natural gas production was due to increased drilling
activities, as well as the Pennzoil Acquisition and other acquisitions of
producing properties. The increase in total net production increased revenues by
$32.8 million. In addition, the Company experienced a 9% increase in average oil
and condensate prices, and a 13% decrease in average natural gas prices.

     As a result of hedging activities, the Company realized an average oil
price of $16.76 per Bbl for the year ended December 31, 1995, compared to an
average price of $15.87 per Bbl that otherwise would have been received. These
hedging activities increased oil revenues by approximately $0.4 million.

     Revenues from IPF Activities increased from $1.4 million in 1994 to $2.4
million in 1995, an increase of $1.0 million, or 66%. This increase was
primarily attributable to GasFund loan activity.

     Lease operating expenses increased from $1.8 million in 1994 to $8.0
million in 1995, an increase of $6.2 million, or 346%. However, on an Mcfe
basis, lease operating expenses decreased from $0.63 in 1994 to $0.39 in 1995, a
decrease of $0.24, or 38%. The decrease in lease operating cost per Mcfe was
primarily attributable to significant increases in production volumes, following
several substantial asset acquisitions.

     DD&A expense increased from $3.1 million in 1994 to $22.7 million in 1995,
an increase of $19.6 million, or 632%. This increase was due to the increase in
oil and gas production volumes and a 5% increase in the DD&A rate.

     General and administrative expense, net of capitalized amounts, increased
from $0.1 million in 1994 to $4.1 million in 1995, an increase of $4.0 million.
The increase includes a $1.3 million corporate overhead allocation from Tenneco.
Excluding the corporate overhead allocation, the remainder of the increase was
primarily attributable to increased staffing requirements resulting from
acquisitions.

     Income tax expense decreased from $1.1 million in 1994 to $0.9 million in
1995, a decrease of $0.2 million, or 22.1%. This was primarily due to a decrease
in the effective tax rate from 53.2% in 1994 to 38.9% in 1995.

     Net income was $1.4 million in 1995 compared to $1.0 million in 1994, as a
result of the factors described above.

LIQUIDITY AND CAPITAL RESOURCES

     Funding for the Company's exploration and development activities,
acquisitions and IPF Program investments has historically been provided by
operating cash flows, revolving credit borrowings, asset sales and advances from
Tenneco. The Company's Board of Directors has authorized a capital budget of
$125.0 million for 1997 to be spent on exploratory and development drilling, IPF
Program investments and acquisitions of oil and gas properties. The Company
intends to finance these expenditures with a portion of the net proceeds from
this Offering, cash flow from operations and borrowings under its revolving
credit facilities.

     As a result of borrowings under the Revolving Credit Facility and the IPF
Company Credit Facility in order to finance a portion of the costs of the
Acquisition, the Company has incurred substantial indebtedness and has minimal
borrowing availability under either of such facilities. As of December 31, 1996,
the Company had total consolidated indebtedness for money borrowed of
approximately $92.7 million. On a

                                       32
<PAGE>
pro forma basis as of December 31, 1996, the Company would have had total
consolidated indebtedness for money borrowed of approximately $25.3 million,
resulting in availability for additional borrowings of $44.2 million and $11.8
million under the Revolving Credit Facility and the IPF Company Credit Facility,
respectively (assuming a borrowing base of $63.3 million and $18.0 million,
respectively.)

     The borrowing base under the Revolving Credit Facility is scheduled to be
redetermined based on the Company's January 1 and June 30, 1997 reserve reports.
Depending on the price outlook for oil and natural gas and the levels of the
Company's cash flows and capital expenditures, the borrowing base may be re-set
below the amounts outstanding under the Revolving Credit Facility, and in such
case the Company may need to refinance a portion of the principal amount of such
indebtedness prior to its maturity. The Company believes that cash flow from
operations, proceeds from the Offering and revolving credit borrowings will be
adequate to meet future liquidity needs, including satisfying the Company's
financial obligations and funding its capital investment program.

     REVOLVING CREDIT FACILITY.  In connection with the Acquisition, the Company
entered into the $65.0 million Revolving Credit Facility maturing on December
31, 1999 with a group of banks led by The Chase Manhattan Bank (the
"Lenders"). The Revolving Credit Facility is secured by approximately 80% of
the aggregate value of the Company's oil and gas properties and substantially
all of the Company's other property (other than IPF Program properties),
including the capital stock of Ventures Corporation and Production Corporation.
Although the remaining approximately 20% of the aggregate value of the Company's
oil and natural gas properties is not mortgaged to the Lenders thereunder, such
properties are nevertheless subject to the restrictions set forth therein,
including a prohibition on granting any security interests therein. The
borrowing base under the facility was $63.3 million as of February 28, 1997, and
is subject to a scheduled redetermination every six months (and such other
redeterminations as the Lenders may elect to perform each year) by the Lenders
at the Lenders' sole discretion and in accordance with their customary practices
and standards in effect from time to time for reserve-based loans to borrowers
similar to the Company. Determination of the borrowing base may be affected by,
among other things, estimates and projections of reserves and production rates
with respect to the Company's oil and natural gas properties and changes in oil
and natural gas prices. The Company's obligations under the Revolving Credit
Facility are guaranteed by its wholly-owned subsidiaries, Ventures Corporation
and Production Corporation.

     If the Company's borrowing base is reduced, the amount available to the
Company under the Revolving Credit Facility will be reduced and, to the extent
that the borrowing base is less than the amount then outstanding thereunder, the
Company will be obligated to provide additional collateral or prepay such excess
amount within 30 days following the date on which the excess amount first
occurred. The borrowing base under the Revolving Credit Facility is scheduled to
be redetermined as of December 31, 1997 and may be reduced substantially from
its current level. All amounts outstanding in excess of such reduced borrowing
base must be paid in full at such date. In addition, if at the end of any fiscal
quarter of the Company during 1997 the amount then outstanding thereunder
exceeds $43.3 million (as such amount may be adjusted from time to time pursuant
to the Revolving Credit Facility), the Company will be obligated to prepay the
outstanding indebtedness thereunder in an amount equal to 100% of the Company's
"excess cash flow" (as defined therein) for such fiscal quarter. Excess cash
flow is defined to include a portion of the net proceeds to the Company of the
Offering.

     Absent a default or an event of default (as defined therein), borrowings
under the Revolving Credit Facility accrue interest at LIBOR plus a margin of
1.50% to 2.50% per annum depending on the total amount outstanding or, at the
option of the Company, at the greater of (i) the prime rate and (ii) the federal
funds effective rate plus 0.50%, plus a margin of 0.50% to 1.50% depending on
the total amount outstanding. The Company incurs a quarterly commitment fee
ranging from 0.375% to 0.50% per annum on the average unused portion of the
Lenders' aggregate commitment, depending on the total amount outstanding.

     The Revolving Credit Facility contains a number of covenants that, among
other things, restrict the ability of the Company to dispose of assets, incur
additional indebtedness or grant liens on its properties,

                                       33
<PAGE>
repay other indebtedness, pay dividends, enter into certain investments or
acquisitions, repurchase or redeem capital stock, engage in mergers or
consolidations, or engage in certain transactions with subsidiaries and
affiliates and that will otherwise restrict corporate activities. In addition,
such facility requires the Company to maintain a specified minimum tangible net
worth and to comply with certain prescribed financial ratios. Further, under
such facility, an event of default is deemed to occur if any person, other than
the Company's officers, Fund VII or any other investment fund, the managing
general partner of which is First Reserve, becomes the beneficial owner,
directly or indirectly, of more than 40% of the outstanding shares of Common
Stock.

     IPF COMPANY CREDIT FACILITY.  IPF Company, an indirect wholly-owned
subsidiary of the Company, has a $20.0 million revolving credit facility with
Compass Bank-Houston pursuant to which it finances a portion of the IPF Program.
The IPF Company Credit Facility matures June 1, 1998 at which time all amounts
owed thereunder are due and payable. The IPF Company Credit Facility is secured
by substantially all of IPF Company's oil and gas interests, including the notes
receivable generated therefrom. The borrowing base under the facility as of
February 28, 1997 was $18.0 million and is subject to a scheduled
redetermination by the lender every six months and such other redeterminations
as the lender may elect to perform each year. As of February 28, 1997,
approximately $11.2 million was outstanding under the IPF Company Credit
Facility. So long as no default or event of default (as defined therein) is
outstanding, borrowings under the IPF Company Credit Facility accrue interest at
LIBOR plus a margin of 2.25% or, at the option of IPF Company, the prime rate
published in THE WALL STREET JOURNAL.

     The IPF Company Credit Facility contains a number of covenants that, among
other things, restrict the ability of IPF Company to incur additional
indebtedness or grant liens on its properties, guarantee indebtedness of any
other person, dispose of assets, make loans in excess of $100,000 other than in
the ordinary course of its business, issue additional shares of capital stock,
engage in certain transactions with affiliates, enter into any new line of
business or amend certain of its material contracts. In addition, such facility
requires IPF Company to maintain a specified minimum tangible net worth.

     The IPF Company Credit Facility restricts the ability of IPF Company to
dividend cash to its parent, Ventures Corporation, or otherwise advance cash to
the Company. As of December 31, 1996, IPF Company net assets of approximately
$8.0 million were restricted.

CAPITAL EXPENDITURES AND FUTURE OUTLOOK

     The following table sets forth the Company's capital expenditures and IPF
Program investments for each of the past three years.

     The Company's Board of Directors has authorized a capital budget of $125.0
million for 1997. The Company expects that $23.0 million of such capital
expenditures will be spent on completion, development and exploitation
activities on 10 Gulf of Mexico lease-blocks and $6.0 million will be spent on
drilling in connection with six exploratory programs. In addition, the Company
expects to invest $36.0 million in new IPF Program assets. The balance of
projected capital expenditures is attributable to $60.0 million in acquisitions
in the Company's core operating area, $30.0 million of which will be used to
finance the Funds Acquisition. The Company expects to finance these expenditures
with proceeds from the Offering, cash flow from operations and borrowings under
the Company's revolving credit facilities.

     Although certain of the Company's costs and expenses may be affected by
inflation, inflationary costs have not had a significant effect on the Company's
results of operations.

OTHER MATTERS

     HEDGING ACTIVITIES.  In an effort to achieve more predictable cash flows
and earnings and reduce the effects of the volatility of the price of oil and
natural gas on the Company's operations, the Company has in the past and may in
the future hedge oil and natural gas prices through the use of commodity
futures, options and swap agreements and other hedge devices. While the use of
these hedging arrangements limits the downside risk of adverse price movements,
it may also limit future gains from favorable movements. The Company accounts
for these transactions as hedging activities and, accordingly, gains and losses
are included in oil and natural gas revenues in the period in which the related
production occurs. The Company does not engage in speculative hedges. The
Revolving Credit Facility imposes certain limitations on the Company's ability
to enter into hedging transactions, but such limitations are not expected to
constrain the Company's hedging activities in any material respect.

     The annual average oil and natural gas prices received by the Company have
fluctuated significantly over the past three years. The Company's weighted
average natural gas price received per Mcf (including the effects of hedging
transactions) was $1.76, $1.54 and $1.96 during the years ended December 31,
1994, 1995, and 1996, respectively. Hedging transactions resulted in a $0.43
reduction in the Company's weighted average natural gas price received per Mcf
in 1996. The Company's weighted average oil price received per Bbl during the
years ended December 31, 1994, 1995 and 1996 was $14.93, $16.76 and $18.60,
respectively. Hedging transactions resulted in a $2.15 reduction in the
Company's weighted average oil price received per Bbl in 1996.

     The following table sets forth the Company's open hedging contracts for oil
and natural gas and the corresponding weighted average prices to be received
under various swap agreements as of March 15, 1997 and, assuming a market price
based on the NYMEX twelve-month strip as of December 31, 1996, the Company's
projected losses from hedging activities from 1997 to 2000.

     NATURAL GAS BALANCING.  The Company incurs certain gas production volume
imbalances in the ordinary course of business and utilizes the sales method to
account for such imbalances. Under this method, income is recorded based on the
Company's net revenue interest in production taken for delivery. Management does
not believe that the Company had any material gas imbalances as of December 31,
1995 or 1996.

     ACCOUNTING PRONOUNCEMENTS.  On October 23, 1995, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("SFAS 123"), which establishes a
fair value method for accounting for stock-based compensation plans either
through recognition or disclosure. SFAS 123 encourages, but does not require,
companies to adopt the fair value method of accounting in place of the existing
intrinsic value method of accounting for stock-based compensation. The Company
currently utilizes the intrinsic value method of accounting and will continue to
use this method. When applicable, the Company will disclose the pro forma
adjustments to net income and earnings per share as required by SFAS 123 in the
notes to the Combined and Consolidated Financial Statements of the Company
included elsewhere in this Prospectus.

                            BUSINESS AND PROPERTIES

THE COMPANY

     Domain is an independent oil and gas company engaged in the exploration,
development, production and acquisition of domestic oil and natural gas
properties, principally in the Gulf Coast region. The Company complements these
activities with its Independent Producer Finance Program (the "IPF Program")
pursuant to which it invests in oil and natural gas reserves through the
acquisition of term overriding royalty interests. The Company's future growth
will be driven by development, exploitation and exploration drilling on its
existing properties, by the continuation of an opportunistic acquisition
strategy in the Gulf Coast region and by further expansion of the IPF Program.

     The Company was formed in December 1996 by the management of Tenneco
Ventures Corporation and an affiliate of First Reserve Corporation to acquire
(the "Acquisition") Tenneco Ventures Corporation and certain of its affiliates
(collectively, "Tenneco Ventures"). Senior management of the Company
established Tenneco Ventures in 1992 as a separate business unit of its former
parent, Tenneco Inc. ("Tenneco"), to engage in exploration and production, oil
and gas program management, producer finance and related activities. All of the
Company's executive officers are veterans of the Tenneco organization, and 11 of
the Company's 19 technical personnel have Tenneco Oil Company backgrounds.
Approximately 90% of the Company's employees, including all of its management,
have purchased shares of Common Stock in the Company.

     During the last four years, the Company has grown primarily through the
opportunistic acquisition of Gulf of Mexico properties and the subsequent
development, exploitation and exploration of these properties, resulting in
substantial increases in its reserves and production. The Company believes that
its acquisition costs, lease operating costs and net general and administrative
costs on a per Mcfe basis are low relative to other companies operating
principally in the Gulf Coast region. From 1994 through 1996, the Company
completed 11 acquisitions aggregating $106.9 million, with an average cost of
proved reserves estimated at the time of acquisition of $0.48 per Mcfe. Eight of
the 11 acquisitions were Gulf Coast region properties. In 1996 the Company
achieved a lease operating expense of $0.44 per Mcfe of production and a net
general and administrative expense (excluding Tenneco overhead allocations) of
$0.12 per Mcfe of production.

     The Company's pro forma estimated net proved reserves as of December 31,
1996 were 153.8 Bcfe, and its pro forma average daily production during 1996 was
85.6 MMcfe, each of which represents a twelvefold increase from levels in 1993.
Approximately 60% of these reserves were natural gas, and approximately 67% of
proved reserves were classified as proved developed producing. On a pro forma
basis as of December 31, 1996, the Company had a PV-10 Reserve Value of $213.0
million, which does not include reserve value attributable to the IPF Program.

     Through the IPF Program, the Company complements its exploration and
production activities by providing capital to independent producers in return
for term overriding royalty interests in oil and gas properties owned by such
producers. From inception through December 31, 1996, the IPF Program has
generated an average return on net assets in excess of 20%. In addition, the
Company believes that the IPF Program offers a lower level of reserve,
production and price risk than that associated with working interest ownership.
From inception through December 31, 1996, the Company completed 40 transactions
under its IPF Program. At December 31, 1996, based on Company estimates and
assuming prices of $2.10 per Mcf of

                                       36
<PAGE>
natural gas and $21.00 per Bbl of oil, the net present value attributable to IPF
Program assets was $25.0 million.

     The Company generated earnings before interest, taxes and depreciation and
amortization ("EBITDA") plus IPF Program return of capital of $41.6 million in
1996, $27.6 million in 1995 and $8.7 million in 1994. IPF Program return of
capital was $4.6 million in 1996, $2.6 million in 1995 and $3.5 million in 1994.
The Company's 1996 pro forma EBITDA plus IPF Program return of capital was $59.2
million.

     The Company's Board of Directors has authorized a capital budget of $125.0
million for 1997. These planned expenditures consist of $23.0 million for
development and exploitation expenditures on the Company's existing Gulf Coast
region properties, $6.0 million for exploratory drilling, $36.0 million for IPF
Program investments and $60.0 million for acquisitions in the Company's core
operating area, $30.0 million of which is pending. See " -- Pending
Transactions -- The Funds Acquisition."

     The Company's principal executive offices are located at 1100 Louisiana,
Suite 1500, Houston, Texas 77002 and its telephone number is (713) 757-5662. The
mailing address of the Company's principal executive offices is P.O. Box 2511,
Houston, Texas 77252.

BUSINESS STRATEGY

     The Company's objective is to maximize shareholder value by growing
reserves, production, cash flow and earnings through the opportunistic
acquisition of Gulf Coast region properties with underexploited value. The
Company applies 3-D seismic and other advanced technologies to development,
exploitation and exploration. These activities are complemented by the continued
expansion of the IPF Program. Fundamental to the execution of the Company's
strategy is its foundation of experienced technical talent strengthened by a
high level of financial, transactional and risk-management expertise resulting,
in part, from the former association of the Company and its employees with
Tenneco.

     GEOGRAPHIC FOCUS.  The Company concentrates its primary oil and gas
activities in the Gulf Coast region, specifically in state and federal waters
off the coast of Texas and Louisiana. The Company believes this region remains
attractive for future development, exploration and acquisition activities. This
is due to the availability of seismic data, significant reserve potential and a
well developed infrastructure of gathering systems, pipelines and platforms with
ready access to drilling services and equipment in the region. In addition, the
Company's relationships with major oil companies and independent producers
operating in the region allow continued access to new opportunities. This
geographic focus has enabled the Company to build and utilize a base of
region-specific geological, geophysical, engineering and production expertise.
The Company's geographic focus allows it to manage a large asset base with
relatively few employees, thus permitting the Company to control expenses and
add Gulf of Mexico production at a relatively low incremental cost.

     ACQUISITION OF PROPERTIES WITH UNDEREXPLOITED VALUE.  The Company employs
an acquisition strategy targeted primarily at purchases of Gulf Coast region
producing properties from major oil companies and large independents. These
properties provide opportunities to increase reserves, production and cash flow
through development and exploitation drilling and lease operating expense
reduction. The Company manages its acquired properties by working proactively
with its joint interest partners to accelerate development, identify
exploitation opportunities and implement cost controls on these properties.

     DEVELOPMENT, EXPLOITATION AND EXPLORATION.  The Company integrates its
reservoir and production engineering expertise with its geologic and seismic
interpretation abilities to enhance the results of its exploration and
production business. The Company applies workovers, recompletions, secondary
recovery operations and other production enhancement techniques on its existing
properties to increase recoverable reserves, production and cash flow.
Additionally, the Company uses advanced technology in both its development and
exploration activities to reduce drilling risks and finding costs and to
prioritize its drilling prospects based on return potential. The Company's
ability to obtain 3-D seismic data and its balanced integration of reservoir and
production engineering with such data allows it to identify multiple development
and exploratory prospects in mature producing fields that were not identified
through earlier

                                       37
<PAGE>
technologies. The Company currently employs six geoscientists with an average
experience level of more than 16 years and operates two geophysical workstations
interpreting 3-D seismic data over twelve fields and six exploratory programs.
The Company intends to expand its geoscience team in 1997.

     The Company has assembled a multiyear inventory of development,
exploitation and exploratory drilling opportunities in the Gulf Coast region and
has identified more than 70 drilling and recompletion opportunities for 1997.
Most of the properties comprising this inventory are located in fields that have
well-established production histories. The Company believes these properties may
yield significant additional recoverable reserves through the application of
advanced exploration and development technologies. The Company participated in
the drilling of nine development wells and 33 exploratory wells in 1996, of
which 78% and 61%, respectively, were successful.

     CONTINUED EXPANSION OF THE IPF PROGRAM.  The Company has leveraged its
expertise in oil and gas reserve appraisal and evaluation to develop and grow
the IPF Program. The Company believes this program offers an attractive
risk/reward balance and stable earnings. The oil and gas companies that
establish a relationship with the Company through the IPF Program often come to
view the Company as a prospective working interest partner for their drilling or
acquisition projects. Management believes that the investment opportunities,
market information and business relationships generated as a result of the IPF
Program provide the Company with a strategic advantage over other independent
oil and gas companies that are not engaged in this business. As a result of the
Company's efficiency in originating and closing IPF Program transactions in the
$0.5 to $5.0 million range, the Company currently encounters only limited
competition from alternate sources of capital for investment in quality
properties and projects of independent oil and gas companies.

     The Company closed six IPF Program transactions in the first quarter of
1997 for an aggregate of $9.1 million. In addition, the Company is currently
evaluating over 30 transactions, all of which satisfy the Company's initial
screening criteria. The Company has budgeted $36.0 million for investment in IPF
Program transactions in 1997.

PENDING TRANSACTIONS

     THE FUNDS ACQUISITION.  The Company previously sponsored and managed two
oil and gas investment programs (collectively, the "Funds") for institutional
investors. The Company has reached an agreement with the investors in the Funds
to acquire certain property interests from such investors upon consummation of
the Offering (the "Funds Acquisition"). These property interests are primarily
located in the Gulf Coast region and have combined proved reserves of 33.0 Bcfe.
Furthermore, these interests include 17,821 net undeveloped leasehold acres with
3-D seismic based exploration potential. The Company expects to acquire these
reserves at an aggregate cost of $30.0 million, effective January 1, 1997, for a
unit cost of $0.65 per Mcfe of net proved reserves. The Funds Acquisition will
provide the Company with a larger interest in certain of its existing
properties, including the West Delta 30 Field in the Gulf of Mexico.

     THE MICHIGAN DISPOSITION.  The Company has substantially completed
negotiations and expects to close the sale of its interests in a natural gas
development project located in northwestern Michigan (the "Michigan Development
Project") in the near future. The Company views this transaction (the
"Michigan Disposition") as a disposition of non-core assets and a further
enhancement of its focus on the Gulf Coast region. The aggregate sales price
including assumption of debt is expected to be $32.2 million net to the
Company's interest. Upon consummation of the transaction, the Company will sell
28.8 Bcfe of proved reserves as of December 31, 1996 (of which 3.3 Bcfe were
proved developed producing as of December 31, 1996) and interests in a pipeline
company and a processing company.

     The Company retained its interests in Oceana Exploration Company, L.C., a
Michigan exploration company. See "Business and Properties -- Exploration
Programs -- Michigan."

DEVELOPMENT, EXPLOITATION AND EXPLORATION PROJECTS

     Set forth below is a description of the development and exploitation
projects that the Company's management expects to pursue during calendar year
1997. While the Company presently intends to

                                       38
<PAGE>
complete these projects, the number, type and timing thereof are subject to
change as a result of many factors, including the availability of capital to
fund such projects, initial test results, results of drilling by third parties
on adjacent blocks, weather, oil and gas prices and other general economic
conditions that are beyond the control of the Company. In addition, because the
Company does not operate most of its properties, it can influence but does not
have the ability to control the initiation and timing of many capital projects.
The Company currently anticipates spending approximately $23.0 million during
calendar year 1997 on some of the following projects. There can be no assurance
that any of these projects can be successfully developed within budget, or that,
once developed, such projects will be commercially productive. See "Risk
Factors -- Volatility of Oil and Natural Gas Prices; Marketability of
Production," "-- Reserve Replacement Risks," "-- Reliance on Estimates of
Oil and Natural Gas Reserves" and "-- Substantial Capital Requirements."

     RABBIT ISLAND FIELD.  In 1993 the Company purchased a 25% interest in the
Rabbit Island Field located in Louisiana state waters. The field has produced in
excess of 1.2 Tcf of gas and 46 MMBbls of oil. A 105 square-mile 3-D survey was
interpreted in 1993, and six of seven wells drilled since that time have been
successful, discovering 34.3 Bcfe of gross proved reserves (7.2 Bcfe net to the
Company's interest). The Company, Texaco Exploration and Production Inc.
("Texaco") and Shell Offshore Inc. ("Shell") are conducting a joint field
study to delineate additional exploitation opportunities in this field. This
study is expected to be completed in the third quarter of 1997. The preliminary
results of the study indicate at least 25 potential exploitation opportunities.

     WEST DELTA 30.  In 1995 the Company purchased a 70% working interest in the
West Delta 30 Field in the Gulf of Mexico from Shell and initiated an integrated
geological, geophysical and 3-D seismic study in the first half of 1996. As a
result of this study, the Company identified eight additional development
drilling locations and three deeper pool prospects that the Company believes
have significant exploratory potential. Based on the Company's proposal, Exxon
Company, U.S.A. ("Exxon"), the operator, has committed to drill a well to test
this field's deeper exploratory potential in mid-year 1997 and a development
well by year-end 1997.

     MATAGORDA ISLAND 519.  In late 1994 the Company purchased 13 producing
fields in the Gulf of Mexico from Pennzoil Company ("Pennzoil") for $51.3
million (the "Pennzoil Acquisition"), including the Matagorda Island 519
Field. The Company owns working interests of 17% and 25% in this field, which is
operated by Amoco Production Company ("Amoco"). Workover operations on three
wells in this field are scheduled to be performed in 1997. Amoco completed such
operations on the first well in January 1997, increasing gross production by 10
MMcf per day, a 50% increase in production attributable to the well. The Company
believes that significant development and exploratory potential remains in the
field. Amoco has purchased a 3-D seismic survey to delineate these
opportunities, in which the Company owns a 25% working interest.

     HIGH ISLAND 110/111.  The Company purchased its initial interest in this
Texaco-operated field as part of the Pennzoil Acquisition and currently holds a
17% working interest. The Company has identified several recompletion zones and
two proved undeveloped drilling locations in the field using 3-D seismic data to
reinterpret an internal field study. These wells are scheduled to be drilled in
1997.

     MUSTANG ISLAND 846/847.  The Company operates and owns a 100% working
interest in this field, which it acquired as part of the Pennzoil Acquisition.
Although the field was previously not producing and scheduled for abandonment by
Pennzoil, the Company initiated a three-well recompletion program on the field
shortly after its acquisition resulting in production of 8.8 MMcf per day. The
Company has conducted a detailed field study and identified a development
location that the Company believes has significant reserve potential. The
Company plans to drill this location by mid-year 1997.

     WASSON FIELD.  In June 1996 the Company acquired a 34.7% working interest
in the Cornell Unit in the Wasson Field in West Texas. Approximately 1.5 billion
Bbls of oil have been produced from the San Andres reservoir from which the
Cornell Unit produces. The field was initially waterflooded in 1965, and a CO2
flood was initiated in 1985 utilizing the water alternating-gas injection method
of enhanced oil recovery. Because the field has been restored to its original
pressure as the result of tertiary recovery

                                       39
<PAGE>
activities, at year-end 1996 the Company recommended the cessation of CO2
purchases for the next four to five years. This recommendation was adopted by
the unit working interest owners. As a result, the Company expects to increase
its annual cash flow from the field by $1.9 million. The Company, working with
unit operator Exxon, has identified up to 30 infill drilling locations.
Furthermore, pressure tests performed recently in an adjoining unit indicate
that the upper gas-bearing sands may be produced separately from the oil
reservoir. Exxon and the Company plan to test the feasibility of producing these
gas-bearing sands in 1997.

PRODUCER INVESTMENT ACTIVITIES

     IPF PROGRAM.  The Company complements its exploration and production
activities with its IPF Program pursuant to which it invests in oil and natural
gas reserves through the acquisition of term overriding royalty interests. From
inception through December 31, 1996, the IPF Program has generated an average
return on assets employed in excess of 20%. The IPF Program was established in
1993 and is funded by a combination of equity provided by the Company and
third-party debt. The IPF Program enables independent producers to obtain
nonrecourse financing, while maintaining ownership of their properties, through
the sale to the Company of term overriding royalty interests. Transaction sizes
for the program generally have ranged from $0.5 million to $5.0 million. A
strong customer focus has resulted in a large majority of IPF Program customers
having returned for additional funding requests and approximately a 100% average
annual growth in year-end customers over the last two years. From inception
through December 31, 1996, the Company completed 40 transactions under the IPF
Program. At December 31, 1996, based on Company estimates and assuming prices of
$2.10 per Mcf of natural gas and $21.00 per Bbl of oil, the net present value
attributable to IPF Program assets was $25.0 million.

     The Company believes that the IPF Program offers a lower level of reserve,
production and price risk than that associated with working interest ownership.
Such risks are mitigated through strict adherence to the Company's IPF Program
underwriting guidelines and the Company structuring its investment to receive an
agreed upon share of revenues from identified properties until a contractual
return is attained. The Company's underwriting guidelines include the
requirement of sufficient reserve value, or collateral coverage, in excess of
the IPF Program investment and the requirement that the IPF Program investments
be structured so as not to bear production expenses. Additionally, because the
Company originates dollar-denominated IPF Program assets, the effect of
commodity price declines on the expected return on these assets is reduced as
compared to working interest ownership. This reduction in price risk occurs
because the Company structures its IPF Program term overriding royalty interests
to result in a contractual return before the overriding royalty interest is
discharged. As a result, IPF Program customers must deliver proceeds from the
sale of oil and gas production until such return is achieved by the Company on
its investment, regardless of the commodity price realized by the customer over
the term of the transaction.

     On June 7, 1996, the Company's indirect wholly-owned subsidiary, IPF
Company, entered into the IPF Company Credit Facility pursuant to which it
finances the purchase of term overriding royalty interests under the IPF
Program. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources -- IPF Company Credit
Facility."

     THE GASFUND.  In May 1993, Ventures Corporation and EnCap Ventures 1993
Limited Partnership ("EnCap") finalized a partnership arrangement named the
GasFund ("GasFund"). The GasFund was a financing vehicle that utilized bank
debt supported by limited Company and EnCap credit enhancements, which provided
production-based financing to independent producers for oil and gas projects
generally exceeding $10.0 million.

     Currently, there are no existing obligations and no outstanding
transactions associated with the GasFund. As a result of the Company's
assessment that the market to provide financing in amounts greater than $10.0
million is competitive to the point of unattractive returns, and the reduced
credit enhancement capabilities of the Company as a result of the Acquisition,
the Company does not anticipate participating in any future GasFund
transactions.

EXPLORATION PROGRAMS

     During 1996 the Company participated in 33 exploration wells with 20
completions, for a 60.6% success rate. In addition to the exploration that the
Company may conduct on its existing properties, the Company intends to continue
participation in exploration activities through various joint venture programs,
including those summarized below.

     SOUTH TEXAS -- COX & PERKINS DRILLING PROGRAM.  The Cox & Perkins drilling
program is an exploration effort in the expanded Yegua gas trend within Jackson
and Wharton Counties, Texas. The Company holds a 10% working interest in this
program, which utilizes 3-D seismic data to delineate potential structural and
stratigraphic traps within the trend. The program sponsor and operator is Cox &
Perkins Exploration, Inc., a privately-held, independent exploration and
production company. Twenty-six wells have been drilled to date, of which 18 are
productive. Current gross daily production from the wells is approximately 42
MMcf of natural gas and 1,070 Bbls of condensate. One well is currently being
drilled, with four additional wells scheduled to be drilled in 1997.

     SOUTH TEXAS -- KENEDY RANCH.  The Kenedy Ranch program is an exploration
effort to delineate expanded Frio reservoir traps on this large ranch in Kenedy
County along the southern Texas Gulf Coast. Output Exploration Company, Inc.,
Hunt Petroleum Company and the Company have shot a 180 square mile 3-D seismic
survey and acquired 49,000 acres in defining potential drill sites. The program
operator is Hunt Petroleum Company. Interpretation of the seismic data has
identified five primary prospect areas. The Company holds a 12.5% working
interest in this project.

     SOUTH LOUISIANA SALT DOMES.  The Company and an affiliate of Shell,
together with the operator, Texaco, are engaged in an effort to delineate the
exploitation and exploration potential of three salt domes in southern
Louisiana, including the Rabbit Island Field. The group is utilizing 3-D seismic
to identify remaining potential. Nine out of 11 wells drilled to date have been
successful, discovering approximately 62.2 Bcfe of gross proved reserves (12.2
Bcfe net to the Company's interest). The Company's net working interest in these
program wells ranges from 7.6% to 25%.

     ANADARKO BASIN.  The Anadarko Basin seismic program is an exploration
effort within the Morrow Sand trend. The Company and the operator, Brigham
Exploration Company, are utilizing 3-D seismic technology to delineate potential
gas reservoirs in the channel-controlled Upper Morrow Sand. Additional
objectives are present both above and below the main objective. The program
participants hold 13,000 gross acres under lease, are pursuing another 12,000
gross acres and hold options on an additional 80,000 gross acres. Six 3-D
seismic surveys have been shot and the evaluation thereof is in progress. Five
wells have been drilled to date with two completions. The Company holds a 70%
working interest in two of the 3-D areas, a 37.5% working interest in three of
the 3-D areas and a 35% working interest in the remainder. Six additional wells
are currently being drilled or are scheduled to be drilled in the first half of
1997.

     PERMIAN BASIN.  The Permian Basin drilling program is an exploration effort
targeting the Strawn Formation. The Company and the operator, Rand Paulson Oil
Company, Inc., a privately-held, independent exploration and production company,
combine 3-D seismic technology with detailed, bio-stratigraphic zonation work to
delineate potential traps. Numerous secondary objectives exist above the primary
targets. The program participants hold 32,000 gross acres under lease. To date,
the Company has participated in nine wells with three completions. Thirteen
additional prospects have been identified on acreage held by the participants
with three wells currently being drilled and three additional wells scheduled to
be drilled by mid-year 1997. The Company holds a 50% working interest in the
program.

     MICHIGAN.  Oceana Exploration Company, L.C., a Texas limited liability
company and 80% owned subsidiary of Ventures Corporation, is obligated to drill,
or cause to be drilled, four exploratory wells in Oceana County, Michigan by the
end of 1997. Two such wells have been permitted and are expected to spud in the
first half of 1997. Through this program, the Company is targeting the Niagaran
reef trend, which the Company believes has significant exploratory potential.

     MATAGORDA ISLAND 519 FIELD.  The Matagorda Island Block 519 Field is
located offshore Texas, approximately 12 miles southeast of Matagorda County, in
approximately 69 feet of water. Amoco discovered the field in 1983 and is the
current operator. Four wells produce gas from lower Miocene Sands at a depth of
approximately 14,800 feet to 17,000 feet. This field is currently producing 58.9
MMcf of gas per day and 134 Bbls of oil per day (7.7 MMcf and 17.4 Bbls net to
the Company's interest). The Company acquired an average 20% working interest in
the field effective October 1, 1994 pursuant to the Pennzoil Acquisition.

     WEST DELTA 30 FIELD.  The West Delta 30 Field is located offshore
Louisiana, approximately 65 miles south-southeast of New Orleans, in
approximately 50 feet of water. The field was discovered in 1954 and has had
over 200 wells drilled, the last of which was drilled in the early 1990s.
Effective January 1, 1995, the Company acquired 28% of Shell's working interests
in this field, which ranged from 50% to 100%. Cumulative production to date is
approximately 300 Bcf of gas and 200 MMBbls of oil and the field currently
produces 4.8 MMcf of gas per day and 1,489 Bbls of oil per day (1.4 MMcf and 417
Bbls net to the Company's interest). Seneca Resources Corporation and Exxon are
the operators of the field. The West Delta 30 Field produces from Pliocene and
Miocene Sands at a depth of approximately 6,500 feet to 11,000 feet that are
trapped against a salt dome feature.

     HIGH ISLAND 110/111 FIELD.  High Island Blocks 110 and 111 are located
offshore Texas, approximately 20 miles offshore of Jefferson County, in
approximately 30 feet of water. The field was discovered in 1973 and is
currently operated by Texaco. The 17.7% average working interest owned by the
Company was acquired from Pennzoil in 1994 and Sonat Exploration Company in
1995. Cumulative production to

                                       42
<PAGE>
date from this field has been approximately 309 Bcf of gas and 2.6 MMBbls of oil
and the field currently produces 8.8 MMcf of gas per day and 170 Bbls of oil per
day (1.3 MMcf and 24.1 Bbls net to the Company's interest). The High Island
110/111 Field produces from Miocene Sands at a depth of approximately 7,500 feet
to 12,500 feet that are trapped in a faulted anticline, downthrown to a major
listric fault.

     MUSTANG ISLAND 846/847 FIELD.  Mustang Island Blocks 846 and 847 are
located offshore Texas, approximately 23 miles south of Corpus Christi in
approximately 124 feet of water. This field was discovered in 1984 and has
produced approximately 16 Bcf of gas. The field is currently producing 4.4 MMcf
of gas per day and 5.0 Bbls of oil per day (3.7 MMcf and 4.2 Bbls net to the
Company's interest). The Company acquired a 100% working interest in this field
as a result of the Pennzoil Acquisition. The Mustang Island 846/847 Field
produces from lower Miocene Sands at a depth of approximately 6,000 feet to
7,200 feet. The reservoir trap is a low relief rollover, downthrown to a
regional fault.

     EUGENE ISLAND 372 FIELD.  Eugene Island Block 372 is located offshore
Louisiana, approximately 168 miles southwest of New Orleans, in approximately
400 feet of water. This field was discovered in 1978 and has produced
approximately 44 Bcf of gas and 1.5 MMBbls of oil from nine wells. Currently,
there are five active wells in this field. The Company acquired its 37.5%
working interest in this field as a result of the Pennzoil Acquisition. The
Eugene Island 372 Field produces from Pleistocene Sands at a depth of
approximately 5,100 feet to 9,900 feet. The reservoir trap is characterized by
complex faulting and highly stratigraphic sands. Unocal Corporation
("Unocal"), the current operator, is in the process of interpreting a new 3-D
seismic survey covering the block and has identified several untested seismic
amplitudes. Work is in progress to evaluate the size and economic viability of
these leads.

     RABBIT ISLAND.  The Rabbit Island Field is located in Louisiana state
waters, approximately 95 miles southwest of New Orleans in approximately ten
feet of water. This field was discovered in 1939 and has produced in excess of
1.2 Tcf of gas and 46 MMBbls of oil. The field is currently producing 32.2 MMcf
of gas per day and 112 Bbls of oil per day (6.1 MMcf and 21.1 Bbls net to the
Company's interest). Benton Oil & Gas Company of Louisiana ("Benton") earned a
50% working interest in this field from Texaco by acquiring and interpreting a
105 square mile 3-D seismic survey across the field. In 1993, the Company bought
a 25% working interest from Benton. In early 1996, Shell acquired Benton,
leaving Texaco, Shell, and the Company as working interest owners. The
productive interval is Miocene Sands at a depth of approximately 1,600 feet to
12,000 feet. The field is a piercement salt dome with associated radial
faulting.

     MAIN PASS 74.  Main Pass Block 74 is located in Louisiana state waters,
approximately 85 miles southeast of New Orleans in approximately 75 feet of
water. This field was discovered in 1981 and is currently operated by Exxon.
Cumulative production from this field has been approximately 20 MMBbls of oil
and 41 Bcf of gas. The Company acquired an average working interest of 14.4% in
this field as a result of the Pennzoil Acquisition. All production from the Main
Pass 74 Field has come from Miocene Puma Sand at a depth of approximately 10,000
feet to 10,500 feet. The reservoir trap is a westerly-dipping, stratigraphic
trap. The Company has identified one additional drilling location within the
field, and Exxon has expressed an interest in drilling a horizontal well into
the reservoir.

     WASSON FIELD.  The Wasson Field is located in Gaines and Yoakum Counties,
Texas, approximately 80 miles northwest of Midland, Texas. In June 1996 the
Company acquired from Kerr-McGee Corporation 34.7% and .17% working interests in
the Cornell and Denver Units at this field, respectively. These two units are
currently producing 40,301 Bbls of oil per day (548.8 Bbls net to the Company's
interest). The Wasson Field was discovered in 1937. The Cornell and Denver Units
are currently operated by Exxon and Altura Energy, Inc. (a joint venture between
Shell and Amoco), respectively. Approximately 1.5 billion barrels of oil have
been produced from the San Andres reservoir. The San Andres produces in both the
Cornell and Denver Units at depths of approximately 5,500 feet to 6,000 feet.
This field was initially waterflooded in 1965, and a CO2 flood was initiated in
1985 utilizing the water-alternating-gas injection method of enhanced oil
recovery.

(1) The present values as of December 31, 1996 were prepared using a weighted
    average sales price of $22.50 per Bbl of oil and $3.38 per Mcf of natural
    gas. The pro forma present values as of December 31, 1996 were prepared
    using a weighted average sales price of $23.63 per Bbl of oil and $3.59 per
    Mcf of natural gas. By comparison, the present values as of December 31,
    1995 were prepared using a weighted average sales price of $18.76 per Bbl of
    oil and $3.30 per Mcf of natural gas.
(2) Except for the standardized measure calculation, excludes minority interest
    attributable to the Michigan Development Project.

     The estimation of reserve data is a subjective process of estimating the
recovery of 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 the available data, the assumptions made, and
engineering and geological interpretation and judgment. Estimates of
economically recoverable oil and natural gas reserves and future net cash flows
therefrom necessarily depend upon a number of variable factors and assumptions,
including historical production from the area compared with production from
other producing areas, the assumed effects of regulation by governmental
agencies and assumptions concerning future oil and natural gas prices, future
operating costs, severance and excise taxes, development costs and workover and
remedial costs, all of which may in fact vary considerably from actual results.
Any such estimates are therefore inherently imprecise, and estimates by other
engineers, or by the same engineers at a different time, might differ materially
from those included herein. Actual prices, production, development expenditures,
operating expenses and quantities of recoverable oil and natural gas reserves
will vary from those assumed in the estimates and it is likely that such
variances will be significant. Any significant variance

                                       44
<PAGE>
from the assumptions could result in the actual quantity of the Company's
reserves and future net cash flow therefrom being materially different from the
estimates set forth in this Prospectus. In addition, the Company's estimated
reserves may be subject to downward or upward revision, based upon production
history, results of future exploration and development, prevailing oil and
natural gas prices, operating and development costs and other factors.

     Estimates with respect to proved undeveloped reserves that may be developed
and produced in the future are often based upon volumetric calculations and upon
analogy to similar types of reserves rather than actual production history.
Estimates based on these methods are generally less reliable than those based on
actual production history. Subsequent evaluation of the same reserves based upon
production history will result in variations, which may be substantial, in the
estimated reserves.

     The present value of future net cash flows shown above should not be
construed as the current market value, or the market value as of December 31,
1996, or any prior date, of the estimated oil and natural gas reserves
attributable to the Company's properties. In accordance with applicable
requirements of the Commission, the estimated discounted future net cash flows
from estimated proved reserves are based on prices and costs as of the date of
the estimate unless such prices or costs are contractually determined at such
date. Actual future prices and costs may be materially higher or lower. Actual
future net cash flows also will be affected by factors such as actual
production, supply and demand for oil and natural gas, curtailments or increases
in consumption by natural gas purchasers, changes in governmental regulations or
taxation and the impact of inflation on costs.

     The Company's PV-10 Reserve Value as of December 31, 1996 was prepared
using a weighted average sales price of $22.50 per Bbl of oil and $3.38 per Mcf
of natural gas. These prices were substantially higher than prices used by the
Company to calculate PV-10 Reserve Value in recent years. The Company estimates
that a substantial decline in prices relative to year-end 1996 would cause a
substantial decline in the Company's PV-10 Reserve Value. For example, compared
to the pro forma data set forth in the above table as of December 31, 1996, a
$0.10 per Mcf decline in natural gas prices, holding all other variables
constant, would decrease the Company's pro forma December 31, 1996 PV-10 Reserve
Value by approximately $6.4 million, or 2.8%, and a $1.00 per Bbl decline in oil
and condensate prices would decrease the Company's PV-10 Reserve Value by
approximately $4.0 million, or 1.8%. While the foregoing calculations should
assist the reader in understanding the effect of a decline in oil or natural gas
prices on the Company's PV-10 Reserve Value, such calculations assume that
quantities of recoverable reserves are constant and therefore would not be
accurate if prices decreased to a level at which reserves would no longer be
economically recoverable.

     In accordance with methodology approved by the Commission, specific
assumptions were applied in the estimates of future net cash flows. Under this
methodology, estimated future net cash flows are determined by reducing
estimated future gross cash flows to the Company for oil and natural gas sales
by the estimated costs to develop and produce the underlying reserves, including
future capital expenditures, operating costs, transportation costs, royalty and
overriding royalty burdens. Estimated future production costs were based on
actual annual production costs incurred during the reported period. A portion of
the Company's proved reserves are undeveloped, and future development costs
thereon were calculated based on a continuation of present economic conditions.

     Future net cash flows were discounted at 10% per annum to arrive at
discounted future net cash flows. The 10% discount factor used to calculate
present value is required by the Commission, but such rate is not necessarily
the most appropriate discount rate. Present value of future net cash flows,
irrespective of the discount rate used, is materially affected by assumptions as
to timing of future natural gas and oil prices and production, which may prove
to be inaccurate. In addition, the calculations of estimated net revenues do not
take into account the effect of certain cash outlays, including among other
things, general and administrative costs, interest expense and dividends.

     The Company's estimated proved reserves have not been filed with or
included in reports to any federal authority or agency.

     The information contained in the foregoing table should not be considered
indicative of future performance, nor should it be assumed that there is
necessarily any correlation between the number of productive wells drilled and
the oil and natural gas reserves generated therefrom.

     From January 1, 1997 through March 15, 1997, the Company participated in
drilling activities on 15 gross wells. Of the 15 wells, 5 (1.4 net) have been
completed as commercial producers, 4 (0.6 net) were dry holes, and 6 (2.3 net)
are currently being drilled.

OIL AND GAS MARKETING

     The Company's production is priced based on short-term spot prices and is
marketed to third parties consistent with industry practices. The Company is
aided by the presence of multiple delivery points near its production in the
Gulf Coast region. From time to time, the Company has hedged a portion of its
oil and gas production to achieve more predictable cash flows and to reduce its
exposure to fluctuations in oil and gas prices. Despite the measures taken by
the Company to attempt to control price risk, 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 United States economy (particularly
the manufacturing sector), foreign imports, political conditions in other
natural gas-producing and oil-producing countries, the actions of OPEC and
domestic government regulation, legislation and policies. Decreases in the
prices of oil and natural gas could have a material 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, transportation economic and regulatory factors may in the future
materially adversely affect the Company's ability to sell its oil or natural gas
production. See "Risk Factors -- Volatility of Oil

                                       48
<PAGE>
and Natural Gas Prices; Marketability of Production" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

COMPETITION

     The Company encounters competition from other companies in all areas of its
operations, including the acquisition of producing properties and its IPF
Program. The Company's competitors include major integrated oil and gas
companies and numerous independent oil and gas companies, individuals and
drilling and income programs and, in the case of its IPF Program, affiliates of
investment, commercial and merchant banking firms and affiliates of large
interstate pipeline companies. 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 oil and gas business for a much longer time than the Company.
Such companies may be able to pay more for productive natural gas and oil
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, and to grow its IPF Program,
will be dependent upon its ability to evaluate and select suitable properties
and to consummate transactions in this highly competitive environment.

REGULATION

     The availability of a ready market for oil and natural gas production
depends upon numerous factors beyond the Company's control. These factors
include regulation of oil and natural gas production, federal, state and local
laws and regulations governing environmental quality and pollution control,
state limits on allowable rates of production by a well or proration unit, the
supply of oil and natural gas available for sale, the availability of adequate
pipeline and other transportation and processing facilities and the marketing of
competitive fuels. For example, a productive natural gas well may be "shut-in"
because of an oversupply of natural gas or the lack of an available natural gas
pipeline in the areas in which the Company conducts its operations. Federal,
state and local laws and regulations generally are intended to prevent waste of
oil and natural gas, protect rights to produce oil and natural gas between
owners in a common reservoir, control the amount of oil and natural gas produced
by assigning allowable rates of production and control contamination of the
environment.

     REGULATION OF OIL AND NATURAL GAS EXPLORATION AND PRODUCTION.  The
Company's exploration and production operations are subject to various types of
regulation at the federal, state and local levels. Such regulation includes
requiring permits for the drilling of wells, maintaining bonding requirements in
order to drill or operate wells, and regulating the location of wells, the
method of drilling and casing wells, the surface use and restoration of
properties upon which wells are drilling and the plugging and abandonment of
wells. The Company's operations are also subject to various conservation laws
and regulations. These include the regulation of the size of drilling and
spacing units or proration units and the density of wells that may be drilled
and unitization or pooling of oil and gas properties. In this regard, some
states allow the forced pooling or integration of tracts to facilitate
exploration while other states rely on voluntary pooling of lands and leases. In
addition, state conservation laws establish maximum rates of production from oil
and natural gas wells, generally prohibit the venting or flaring of natural gas
and impose certain requirements regarding the ratability of production. The
effect of these regulations is to limit the amounts of oil and natural gas the
Company's operator or the Company can produce from its wells, and to limit the
number of wells the Company can drill or the locations thereof. In addition,
numerous departments and agencies, both federal and state, are authorized by
statute to issue rules and regulations binding on the oil and gas industry and
its individual members, some of which carry substantial penalties for failure to
comply. The regulatory burden on the oil and gas industry increases the
Company's cost of doing business and, consequently, affects its profitability.
Inasmuch as such laws and regulations are frequently expanded, amended or
reinterpreted, the Company is unable to predict the future cost or impact of
complying with such regulations.

                                       49
<PAGE>
     NATURAL GAS MARKETING AND TRANSPORTATION.  Federal legislation and
regulatory controls in the United States have historically affected the price of
the natural gas produced by the Company and the manner in which such production
is marketed. The transportation and sale for resale of natural gas in interstate
commerce are regulated pursuant to the Natural Gas Act of 1938 (the "NGA"),
the Natural Gas Policy Act of 1978 (the "NGPA") and the Federal Energy
Regulatory Commission (the "FERC"). Although maximum selling prices of natural
gas were regulated in the past, on July 26, 1989, the Natural Gas Wellhead
Decontrol Act of 1989 ("Decontrol Act") was enacted, which amended the NGPA to
remove completely by January 1, 1993 price and nonprice controls for all "first
sales" of domestic natural gas, which include all sales by the Company of its
production; consequently, sales of the Company's natural gas production
currently may be made at market prices, subject to applicable contract
provisions. The FERC's jurisdiction over natural gas transportation was
unaffected by the Decontrol Act.

     The FERC also regulates interstate natural gas transportation rates and
service conditions, which affect the marketing of natural gas produced by the
Company, as well as the revenues received by the Company for sales of such
natural gas. Since the latter part of 1985, the FERC has endeavored to make
interstate natural gas transportation more accessible to natural gas buyers and
sellers on an open and nondiscriminatory basis. The FERC's efforts have
significantly altered the marketing and pricing 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 interstate pipelines to
"restructure" to provide transportation separate or "unbundled" from the
pipelines' sales of natural gas. Also, Order No. 636 requires pipelines to
provide open-access transportation on a basis that is equal for all natural gas
supplies. Order No. 636 has been implemented through negotiated settlements in
individual pipeline service restructuring proceedings. In many instances, the
result of the Order No. 636 and related initiatives has been to reduce
substantially or bring to an end the interstate pipelines' traditional role as
wholesalers of natural gas in favor of providing only storage and transportation
services. The FERC has issued final orders in virtually all pipeline
restructuring proceedings, and has now commenced a series of one year reviews to
determine whether refinements are required regarding individual pipeline
implementations of Order No. 636.

     Recently, the FERC issued policy statements on how interstate natural gas
pipelines can recover the costs of new pipeline facilities and on how the FERC
intends to regulate natural gas gathering facilities owned (or previously owned
but either "spun down" to an affiliate or "spun off" to a non-affiliate) by
interstate pipeline companies after Order No. 636. While the FERC's policy
statement on new construction cost recovery affects the Company only indirectly,
in its present form, the new policy should enhance competition in natural gas
markets and facilitate construction of gas supply laterals. However, requests
for rehearing of this policy statement are currently pending. The FERC has
approved the spin down or spin off by several interstate pipelines of their
gathering facilities. These approvals were given despite the strong protests of
a number of producers concerned that any diminution in FERC's oversight of
interstate pipeline-related gathering services might result in a denial of open
access or otherwise enhance the pipelines' monopoly power. While the FERC has
stated that it will retain limited jurisdiction over such gathering facilities
and will hear complaints concerning any denial of access, it is unclear what
effect the FERC's new gathering policy will have on producers such as the
Company and the Company cannot predict what further action the FERC will take on
these matters.

     Proposals and proceedings that might affect the natural gas industry are
considered from time to time by Congress, the FERC, state regulatory bodies and
the courts. The Company cannot predict when or if any such proposals might
become effective, or their effect, if any, on the Company's operations. The
natural gas industry historically has been very heavily regulated; therefore,
there is no assurance that the less stringent regulatory approach recently
pursued by the FERC and Congress will continue indefinitely into the future.

     FEDERAL OFFSHORE LEASING.  Certain of the Company's operations are
conducted on federal oil and gas leases administered by the Minerals Management
Service ("MMS"). The MMS issues such leases through competitive bidding. These
leases contain relatively standardized terms and require compliance with
detailed MMS regulations and orders pursuant to the Outer Continental Shelf
Lands Act ("OCSLA") (which are subject to change by the MMS). For offshore
operations, lessees must obtain MMS approval for

                                       50
<PAGE>
exploration plans and development and production plans prior to the commencement
of such operations. In addition to permits required from other agencies (such as
the Coast Guard, the Army Corps of Engineers and the Environmental Protection
Agency), lessees must obtain a permit from the MMS prior to the commencement of
drilling. The MMS has promulgated regulations requiring offshore production
facilities located on the Outer Continental Shelf ("OCS") to meet stringent
engineering and construction specifications, and has recently proposed
additional safety-related regulations concerning the design and operating
procedures for OCS production platforms and pipelines. The MMS also has issued
regulations restricting the flaring or venting of natural gas, and has recently
proposed to amend such regulations to prohibit the flaring of liquid
hydrocarbons and oil without prior authorization. Similarly, the MMS has
promulgated other regulations governing the plugging and abandonment of wells
located offshore and the removal of all production facilities. To cover the
various obligations of lessees on the OCS, the MMS generally requires that
lessees post substantial bonds or other acceptable assurances that such
obligations will be met. The cost of such bonds or other security can be
substantial and there is no assurance that the Company can obtain bonds or other
security in all cases. See " -- Environmental Matters."

     The MMS has recently issued a notice of proposed rulemaking in which it
proposes to amend its regulations governing the calculation of royalties and the
valuation of natural gas produced from federal leases. The principal feature in
the amendments, as proposed, would establish an alternative market-index based
method to calculate royalties on certain natural gas production sold to
affiliates or pursuant to non-arm's-length contracts. The MMS has proposed this
rulemaking to facilitate royalty valuation in light of changes in the natural
gas marketing environment. The Company cannot predict what action the MMS will
take on these matters, nor can it predict at this state of the rulemaking
proceeding how the Company might be affected by amendments to the regulations.

     The OCSLA requires that all pipelines operating on or across the OCS
provide open-access, non-discriminatory service. Although the FERC has opted not
to impose the regulations of Order No. 509, which implements these requirements
of the OCSLA, on gatherers and other non-jurisdictional entities, the FERC has
retained the authority to exercise jurisdiction over those entities if necessary
to permit non-discriminatory access to services on the OCS. If the FERC were to
apply Order No. 509 to gatherers in the OCS, eliminate the exemption of
gathering lines, and redefine its jurisdiction over gathering lines, the result
would be a reduction in available pipeline space for existing shippers in the
Gulf of Mexico and elsewhere.

     OIL SALES AND TRANSPORTATION RATES.  Sales of crude oil, condensate and gas
liquids by the Company are not regulated and are made at market prices. The
price the Company receives from the sale of these products is affected by the
cost of transporting the products to market. Effective as of January 1, 1995,
the FERC implemented regulations establishing an indexing system for
transportation rates for oil pipelines, which, subject to certain conditions and
limitations, would generally index such rates to inflation. The Company is not
able to predict with certainty what effect, if any, these regulations will have
on it, but other factors being equal, under certain conditions the regulations
may cause increased transportation costs and may reduce wellhead prices for such
commodities.

ENVIRONMENTAL MATTERS

     The Company's operations are subject to federal, state and local laws and
regulations governing the discharge of materials into the environment or
otherwise relating to environmental protection. These laws and regulations may
require the acquisition of a permit before drilling commences, restrict the
types, quantities and concentration of various substances that can be released
into the environment in connection with drilling and production activities,
limit or prohibit drilling activities on certain lands lying within wilderness,
wetlands and other protected areas, require remedial measures to prevent
pollution from former operations, such as pit closure and plugging abandoned
wells, and impose substantial liabilities for pollution resulting from the
Company's operations. In addition, these laws, rules and regulations may
restrict the rate of oil and natural gas production below the rate that would
otherwise exist. The regulatory burden on the oil and gas industry increases the
cost of doing business and consequently affects its profitability. Changes in
environmental laws and regulations occur frequently, and any changes that result
in more stringent and costly waste handling, disposal and clean-up requirements
could have a significant impact on the operating

                                       51
<PAGE>
costs of the Company, as well as the oil and gas industry in general. Management
believes that the Company is in substantial compliance with current applicable
environmental laws and regulations and that continued compliance with existing
requirements will not have a material adverse impact on the Company.

     The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without
regard to fault or the legality of the original conduct, on certain classes of
persons who are considered to be responsible for the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or sites where the release occurred and companies that
disposed or arranged for the disposal of the hazardous substances. Under CERCLA,
such persons may be subject to joint and several liability for the costs of
cleaning up the hazardous substances that have been released into the
environment (including pre-remedial investigations and post-remedial
monitoring), for damages to natural resources. In some instances, neighboring
landowners and other third parties file claims based on common law theories of
tort liability for personal injury and property damage allegedly caused by the
release of hazardous substances at a CERCLA site.

     The Oil Pollution Act of 1990 (the "OPA") and regulations thereunder
impose a variety of requirements on "responsible parties" related to the
prevention of oil spills and liability for damages resulting from such spills in
"waters of the United States." A "responsible party" includes the owner or
operator of a facility or vessel, or the lessee or permittee of the area in
which an offshore facility is located. The term "waters of the United States"
has been broadly defined to include not only the waters of the Gulf of Mexico
but also inland waterbodies, including wetlands, playa lakes and intermittent
streams. A 1996 amendment to the OPA also requires owners and operators of
"offshore facilities" (including those located in coastal inland waters, such
as bays or estuaries) to establish $35.0 million in financial responsibility to
cover environmental cleanup and restoration costs likely to be incurred in
connection with an oil spill. Offshore facilities are facilities used for
exploring for, drilling for or producing oil or transporting oil from facilities
engaged in oil exploration, drilling or production. If it is determined that an
increase in the amount of financial responsibility required is warranted, the
President has the authority to raise such to an amount not exceeding $150.0
million. In any event, the impact of any adjustment to the annual required
financial responsibility is not expected to be any more burdensome to the
Company than it will be to other similarly situated companies involved in oil
and gas exploration and production.

     OPA imposes a variety of additional requirements on responsible parties for
vessels or oil and gas facilities related to the prevention of oil spills and
liability for damages resulting from such spills in waters of the United States.
OPA assigns liability to each responsible party for oil spill removal costs and
a variety of public and private damages from oil spills. OPA establishes a
liability limit for offshore facilities of all removal costs plus $75.0 million.
A party cannot take advantage of liability limits if the spill is caused by
gross negligence or willful misconduct or resulted from violation of a federal
safety, construction or operating regulation. If a 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 for oil spills imposed by OPA. OPA also
imposes other requirements on facility operators, such as the preparation of an
oil spill contingency plan. Failure to comply with ongoing requirements or
inadequate cooperation in a spill event may subject a responsible party to civil
or criminal enforcement actions. As of the date hereof, the Company is not the
subject of any civil or criminal enforcement actions under the OPA and is in
substantial compliance with the requirements of the OPA.

     In addition, the OCSLA authorizes regulations relating to safety and
environmental protection applicable to lessees and permittees operating in the
OCS. Specific design and operational standards may apply to OCS vessels, rigs,
platforms, vehicles and structures. Violations of lease conditions or
regulations issued pursuant to OCSLA can result in substantial civil and
criminal penalties, as well as potential court injunctions curtailing operations
and the cancellation of leases. Such enforcement liabilities can result from
either governmental or private prosecution. As of the date hereof, the Company
is not the subject of any civil or criminal enforcement actions under the OCSLA
and is in substantial compliance with the requirements under the OCSLA.

                                       52
<PAGE>
     The Clean Water Act ("CWA") imposes restrictions and strict controls
regarding the discharge of produced waters and other oil and gas wastes into
navigable waters. Permits must be obtained to discharge pollutants into state
and federal waters. The CWA provides for civil, criminal and administrative
penalties for any unauthorized discharges of oil and other hazardous substances
in reportable quantities and, along with the OPA, imposes substantial potential
liability for the costs of removal, remediation and damages. State laws for the
control of water pollution also provide civil, criminal and administrative
penalties and liabilities in the case of a discharge of petroleum or its
derivatives into state waters. The U.S. Environmental Protection Agency
("EPA") issued general permits prohibiting the discharge of produced water and
produced sand derived from oil and gas point source facilities into coastal
waters in Louisiana and Texas, which became effective as of January 1, 1997.
Although the costs of compliance with zero discharge mandates under federal or
state law may be significant, the entire industry will experience similar costs
and the Company believes that these costs will not have a material adverse
impact on the Company's financial condition and operations. Certain oil and gas
exploration and production facilities are required to obtain permits for their
storm water discharges and costs may be associated with treatment of wastewater,
or developing storm water pollution prevention plans. In addition, the Coastal
Zone Management Act authorizes state implementation and development of
management measures for nonpoint source pollution designed to restore and
protect coastal waters.

OPERATING HAZARDS AND DRILLING RISKS

     The oil and natural gas business involves a variety of operating risks,
including the risk of fire, explosions, blow-outs, pipe failure, abnormally
pressured formations and environmental hazards such as oil spills, gas leaks,
ruptures or discharges of toxic gases. Any of these occurrences could result in
substantial losses to the Company due to injury or loss of life, severe damage
to or destruction of property, natural resources and equipment, pollution or
other environmental damage, clean-up responsibilities, regulatory investigation
and penalties and suspension of operations. Moreover, offshore operations are
subject to a variety of operating risks peculiar to the marine environment, such
as hurricanes or other adverse weather conditions, to more extensive
governmental regulation, including regulations that may, in certain
circumstances, impose strict liability for pollution damage, and to interruption
or termination of operations by governmental authorities based on environmental
or other considerations. The presence of unanticipated pressure or
irregularities in formations, miscalculations or accidents may cause such
activity to be unsuccessful, resulting in a total loss of the Company's
investment in such activity. Although the Company maintains insurance coverage
considered to be customary in the industry, it is not fully insured against
certain of these risks, either because such insurance is not available or
because of the high premium costs. The Company does not carry business
interruption insurance. There can be no assurance that any insurance obtained by
the Company will be adequate to cover any losses or liabilities, or that such
insurance will continue to be available or available on terms which are
acceptable to the Company. See "Risk Factors -- Operating Risks."

     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
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, mechanical problems, compliance with governmental
requirements and shortages or delays in the delivery of equipment and services.
The Company's future drilling activities may not be successful and, if
unsuccessful, such failure may have a material adverse effect on the Company's
future results of operations and financial condition.

     In addition, the Company's use of 3-D seismic requires greater pre-drilling
expenditures than traditional drilling strategies. Although the Company believes
that its use of 3-D seismic will increase the probability of success of its
exploratory wells and should reduce average finding costs through the

                                       53
<PAGE>
elimination of prospects that might otherwise be drilled solely on the basis of
2-D seismic data and other traditional methods, unsuccessful wells are likely to
occur. There can be no assurance that the Company's participation in drilling
programs will be successful or that unsuccessful drilling efforts will not have
a material adverse effect on the Company.

ABANDONMENT COSTS

     The Company is responsible for the payment of abandonment costs on its oil
and natural gas properties pro rata to its working interest. The Company accrues
for its expected future abandonment liabilities as a component of depletion,
depreciation and amortization as the properties are produced. As of December 31,
1996, total pro forma undiscounted abandonment costs estimated to be incurred
through the year 2006 were approximately $16.6 million for properties in federal
and state waters. The Company does not consider abandonment costs estimated to
be incurred on its onshore properties to be significant at this time. Estimates
of abandonment costs and their timing may change due to many factors, including
actual drilling and production results, inflation rates, and changes in
environmental laws and regulations.

     The MMS requires lessees of OCS properties to post bonds in connection with
the plugging and abandonment of wells located offshore on the federal OCS and
the removal of all production facilities. Operators in the OCS waters of the
Gulf of Mexico are currently required to post an area-wide bond of $3.0 million
or $500,000 per producing lease, which the Company has provided. Under certain
circumstances, the MMS has the authority to suspend or terminate operations on
federal leases for failure to comply with the applicable bonding requirements or
other regulations applicable to plugging and abandonment. Any such suspensions
or terminations of the Company's operations could have a material adverse effect
on the Company's financial condition and results of operations.

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. Prior to completing an acquisition of producing oil and natural gas
leases, the Company obtains title opinions on the most significant leases.
However, as is customary in the oil and gas industry, the Company makes only a
cursory review of title to farmout acreage and to undeveloped oil and natural
gas properties upon execution of the contracts pursuant to which the Company
acquires rights thereto. Prior to the commencement of drilling operations, a
thorough title examination is conducted and curative work is performed with
respect to significant defects. To the extent title opinions or other
investigations reflect title defects affecting farmout acreage or undeveloped
properties, the Company, rather than the seller of the undeveloped property, is
typically responsible for curing any such title defects at its expense. If the
Company were unable to remedy or cure any title defect of a nature such that it
would not be prudent to commence drilling operations on the property, the
Company could suffer a loss of its entire investment in the property. The
Company has obtained title opinions on substantially all of its producing
properties and believes that it has satisfactory title to such properties in
accordance with standards generally accepted in the oil and gas industry.

     The Company's oil and natural gas properties are subject to customary
royalty interests, 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. Approximately 80% of the aggregate value of the Company's oil and
natural gas properties (other than the IPF Program properties) are and will
continue to be mortgaged to secure borrowings under the Revolving Credit
Facility. Although the remaining approximately 20% of the aggregate value of the
Company's oil and natural gas properties are not mortgaged to the Lenders under
the Revolving Credit Facility, such properties are nevertheless subject to the
restrictions set forth therein, including a prohibition on granting any security
interests therein.

EMPLOYEES

     On February 28, 1997, the Company employed 38 full-time persons and four
full-time contractors. The Company believes that its relationships with its
employees are good. None of the Company's employees are covered by a collective
bargaining agreement.

                                       54
<PAGE>
OFFICES

     The Company currently leases approximately 31,000 square feet of office
space in Houston, Texas, where its principal offices are located.

LEGAL PROCEEDINGS

     Various claims have been filed naming joint working interest owners of the
Company in the ordinary course of business, particularly claims alleging
personal injuries, for which the Company would be responsible for its pro rata
share of any uninsured damages or settlement costs. In addition, the Company's
partner in the Michigan Development Project has informed the Company that it
believes that is has a preferential purchase right with respect to a portion of
the Company's interests in the project that the Company plans to sell to another
party pursuant to the Michigan Disposition. Such partner has indicated that it
may take legal action to enforce its alleged preferential purchase right and
prevent the Company from consummating the Michigan Disposition. The Company
believes that such partner's claim has no merit and intends to proceed with the
Michigan Disposition. No pending or threatened claims, actions or proceedings
against the Company are expected to have a material adverse effect on the
Company's financial condition or results of operations.

     The Company's Board of Directors currently has four members. Following the
Offering, the Company intends to increase the size of its Board of Directors to
six persons. The two individuals to be nominated for appointment to the Board of
Directors following the Offering will not be employees of or otherwise
affiliated with the Company, Fund VII or First Reserve. The new directors will
be elected by the current directors. All directors are elected annually to serve

COMMITTEES OF THE BOARD OF DIRECTORS

     Following the Offering the Company will have an Audit Committee and a
Compensation Committee.

     AUDIT COMMITTEE.  The Board of Directors intends to name directors to an
Audit Committee after consummation of the Offering. The Audit Committee will
have responsibility for, among other things, (i) recommending the selection of
the Company's independent accountants, (ii) reviewing and approving the scope of
the independent accountants' audit activity and extent of non-audit services,
(iii) reviewing

                                       57
<PAGE>
with management and the independent accountants the adequacy of the Company's
basic accounting systems, (iv) reviewing with management and the independent
accountants the Company's financial statements and exercising general oversight
of the Company's financial reporting process and (v) reviewing the Company's
litigation and other legal matters that may affect the Company's financial
condition and monitoring compliance with the Company's business ethics and other
policies.

     COMPENSATION COMMITTEE.  The Compensation Committee consists of Messrs.
Ronca, Linker and Pruett. This committee has general supervisory power over, and
the power to grant options under, the Stock Purchase and Option Plan. The
Compensation Committee additionally has responsibility for, among other things,
(i) reviewing the recommendations of the Chief Executive Officer as to
appropriate compensation of the Company's principal executive officers and
certain other key personnel and establishing the compensation of such key
personnel and the Chief Executive Officer, (ii) examining periodically the
general compensation structure of the Company and (iii) supervising the employee
benefit plans and compensation plans of the Company.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During the Company's fiscal year ended December 31, 1996, the Company had
no compensation committee or other committee of the Board of Directors
performing similar functions. Decisions concerning compensation of Mr. Ronca
were made during such fiscal year by the Compensation Committee of the board of
directors of Tenneco, the former indirect parent of the Company's operating
subsidiaries. Decisions concerning compensation of the other executive officers
of the Company were made during fiscal year 1996 by the compensation committee
of Tennessee Gas Pipeline Company, the former parent of the Company's operating
subsidiaries. Mr. Ronca served as a member of the compensation committee of
Tennessee Gas Pipeline Company during fiscal year 1996.

RONCA EMPLOYMENT AGREEMENT

     In connection with the Acquisition, the Company entered into a three-year
employment agreement with Mr. Ronca on December 31, 1996 pursuant to which Mr.
Ronca serves as the Company's President and Chief Executive Officer. Under the
Ronca Employment Agreement, Mr. Ronca receives an annual base salary of $180,000
and is entitled to receive an annual cash bonus based on the satisfaction of
performance criteria determined by the Board of Directors, in target and maximum
amounts equal to 50% and 90%, respectively, of such base salary. The Ronca
Employment Agreement also provides that Mr. Ronca will receive $20,000 annually
to be used, at his discretion, for perquisites and other fringe benefits
associated with his position as President and Chief Executive Officer of the
Company. Mr. Ronca is additionally entitled to participate in all other employee
compensation and welfare benefit plans and programs available to the Company's
other senior executive officers, including health, dental, group life,
disability and retirement plans, and expense reimbursement. In the event Mr.
Ronca's employment is terminated prior to December 31, 1999 and under certain
circumstances, including an election by Mr. Ronca to terminate his employment
following a Change of Control (as therein defined) or for Good Reason (as
therein defined), he would be entitled under such employment agreement to
receive up to the full amount of the base salary he would have received
thereunder for the remaining term thereof had his employment not been so
terminated. Under the Ronca Employment Agreement, a "Change of Control" is
defined as the acquisition by any person or entity, or group thereof, excluding
Fund VII and other affiliates of First Reserve of more than 50% of the
outstanding voting stock of the Company, and "Good Reason" is defined to
include, among other things, material reductions in Mr. Ronca's duties,
responsibilities or base salary.

COMPENSATION OF DIRECTORS

     Prior to the Offering, directors of the Company have not received
compensation for their services in such capacity. The Company anticipates that,
after consummation of the Offering, directors who are employees of the Company
will not be paid any fees or additional compensation for service as members of
the Board of Directors or any committee thereof and that the Company will enter
into customary

                                       58
<PAGE>
arrangements respecting fees and other compensation (including expense
reimbursement) for other directors of the Company.

EXECUTIVE COMPENSATION

                           SUMMARY COMPENSATION TABLE

     The following table sets forth certain information with respect to the
compensation of the Company's chief executive officer and for each of its other
executive officers (the "named executive officers") during fiscal year 1996.

STOCK PURCHASE AND OPTION PLAN

     The Company recently adopted the Amended and Restated 1996 Stock Purchase
and Option Plan for Key Employees of Domain Energy Corporation and Affiliates
(the "Stock Purchase and Option Plan"). The objectives of the Stock Purchase
and Option Plan are (i) to attract and retain management personnel with the
training, experience and ability to enable them to make a substantial
contribution to the success of the Company's business, (ii) to motivate
management personnel by means of growth-related incentives to achieve long range
goals and (iii) to further the alignment of interests of participants with those
of the Company's stockholders through opportunities for increased stock or
stock-based ownership in the Company.

     The Stock Purchase and Option Plan authorizes the issuance of options to
acquire up to 867,100 shares of Common Stock, and the Company has reserved
867,100 shares of Common Stock for issuance in connection therewith. The Stock
Purchase and Option Plan will be administered by the Compensation Committee of
the Board of Directors. Pursuant to the Stock Purchase and Option Plan, the
Company may grant to employees, directors or other persons having a unique
relationship with the Company or its affiliates, singly or in combination,
Incentive Stock Options, Other Stock Options, Stock Appreciation Rights,
Restricted Stock, Purchase Stock, Dividend Equivalent Rights, Performance Units,
Performance Shares or Other Stock-Based Grants, in each case as such terms are
defined therein. See " -- Stock Option Agreements." The terms of any such
grant will be determined by the Compensation Committee and set forth in a
separate grant agreement. The exercise price will be at least equal to 100% of
fair market value of the Common Stock on the date of grant in the case of
Incentive Stock Options and the exercise price of Other Stock Options will be at
least equal to 50% of fair market value of the Common Stock on the date of
grant, provided that options to purchase up to 433,550 shares of Common Stock
may be granted with an exercise price equal to $.01 per share, which is the par
value of the Common Stock. Non-Qualified Stock Options and Other Stock Options
may be exercisable for up to ten years. The Compensation Committee

                                       59
<PAGE>
may provide that an optionee may pay for shares upon exercise of an option: (i)
in cash; (ii) in already-owned shares of Common Stock; (iii) by payment through
a cash or margin arrangement with a broker; (iv) in shares otherwise issuable
upon exercise of the option; or (v) by any combination of (i) through (iv) as
authorized by the Compensation Committee. In the event of certain extraordinary
transactions, including a merger, consolidation, a sale or transfer of all or
substantially all assets or an acquisition of all or substantially all the
Common Stock, vesting of such options will generally be accelerated. The Stock
Purchase and Option Plan will terminate on December 31, 2006.

STOCK OPTION AGREEMENTS

     On February 21, 1997 (the "Grant Date"), the Company granted to the
following persons the following options under the Stock Purchase and Option
Plan, pursuant to separate Non-Qualified Stock Option Agreements between the
Company and each of such persons (collectively, as amended, the "Stock Option
Agreements"): (i) an option to purchase up to 339,300 shares of Common Stock to
Michael V. Ronca, the President and Chief Executive Officer of the Company, (ii)
an option to purchase up to 113,100 shares of Common Stock to Herbert A.
Newhouse, an Executive Vice President of the Company, (iii) an option to
purchase up to 113,100 shares of Common Stock to Catherine L. Sliva, an
Executive Vice President and the Secretary of the Company, (iv) an option to
purchase up to 50,267 shares of Common Stock to Rick G. Lester, a Vice
President, the Chief Financial Officer and the Treasurer of the Company, (v) an
option to purchase up to 50,267 shares of Common Stock to Douglas H. Woodul, the
Vice President -- Production of the Company, (vi) an option to purchase up to
50,267 shares of Common Stock to Steven M. Curran, the Vice
President -- Exploration of the Company, (vii) an option to purchase up to
18,850 shares of Common Stock to Dean R. Bouillion, the Vice President -- Land
of the Company, and (viii) an option to purchase up to 18,850 shares of Common
Stock to Lucynda S. Herrin, an Assistant Controller of the Company. In addition,
the Company has granted options to purchase an aggregate of 95,162 shares of
Common Stock to other employees of the Company. Under the terms of the Stock
Option Agreements, 50% of the options granted to each such person are designated
as time options (collectively, the "Time Options"), with an exercise price
equal to $4.18 per share, and 50% are designated as performance options
(collectively, the "Performance Options"), with an exercise price equal to
$.01 per share. The Time Options become exercisable as to 20% of the shares of
Common Stock subject thereto on the first anniversary of the Grant Date and are
thereafter exercisable as to an additional 20% of such shares upon each
anniversary thereafter. The Performance Options become exercisable at any time
following the second anniversary of the Grant Date, when the Investment Return
Hurdle (as such term is defined below) is met; provided that the Performance
Options become exercisable as to 100% of the shares of Common Stock subject
thereto on the ninth anniversary of the Grant Date.

     The following terms have the following meanings under the Stock Option
Agreements:

     "EQUITY VALUE" means the sum of:

      (i)  all amounts actually received by the FRC Entities from time to time
           on a cumulative basis through the date of determination of (A) cash
           (x) through any cash dividend or other distribution on account of the
           Investor Stock or (y) in connection with either (1) any disposition
           (whether by way of redemption, repurchase, repayment, merger or
           otherwise) of all or any part of the Investor Stock or of securities
           or other non-cash property previously received by way of a dividend
           or other distribution on account of the Investor Stock, but only to
           the extent Investor Stock or other securities or non-cash property is
           so disposed and excluding any disposition to one or more other FRC
           Entities, (2) a disposition of any or all of the assets of the
           Company or any of its subsidiaries, or (3) a recapitalization of the
           Company or its subsidiaries, or (B) securities or any other non-cash
           property (valued at their fair market value) in connection with
           either (x) any disposition (whether by sale, merger or otherwise) of
           all or any part of the Investor Stock to a third party, but only to
           the extent Investor Stock is so disposed and excluding any
           disposition to one or more other FRC Entities, or (y) any disposition
           of any or all of the assets of the Company or any of its subsidiaries
           (it being understood that for purposes of this clause (i), the terms
           "disposition," "dispose," and "disposed" shall not include the
           creation of a pledge, lien or

                                       60
<PAGE>
           other similar encumbrance unless and until foreclosed upon);
           PROVIDED, that when determining the amount actually received by the
           FRC Entities after delivery of a notice that the options will be
           terminated upon the merger of the Company, the exchange of all or
           substantially all of its assets for the securities of another
           Company, a Change of Control, or the recapitalization,
           reclassification, liquidation or dissolution of the Company, the
           amount actually received will be deemed to include any amounts to be
           received by the FRC Entities pursuant to the transaction giving rise
           to the termination of the options (to the extent such amounts would
           otherwise qualify as amounts received pursuant to clauses (A) and (B)
           above); plus, if applicable,

     (ii)  to the extent the Equity Value is being determined prior to the fifth
           anniversary of the Grant Date, an amount with respect to each unsold
           share of Common Stock then owned by the FRC Entities equal to the
           Trading Value (as therein defined) thereof as of such date.

     "FRC ENTITIES" means investment funds or other entities for which First
Reserve acts as a general and/or managing partner or in respect of which First
Reserve provides investment advice, either directly or through entities
controlled by it.

     "INVESTMENT" means $30.0 million invested by the FRC Entities in Investor
Stock on the closing date of the Acquisition, plus the amount of any additional
cash invested by the FRC Entities in Investor Stock after such closing date.
Expressly excluded from such term is the $8.0 million loan made by Fund VII to
Domain Energy Guarantor Corporation and evidenced by the Subordinated Promissory
Note dated December 31, 1996. See "Certain Transactions -- Indebtedness to Fund
VII."

     "INVESTMENT RETURN HURDLE" will be satisfied when the Equity Value with
respect to the Investor Stock is equal to or greater than, as of the date of
determination, the amount determined by increasing the Investment at a
compounded annual rate of 25% commencing on the date of any cash investment by
the FRC Entities (as to that portion of the Investment made on such date)
through and including such date of determination.

     "INVESTOR STOCK" means issued and outstanding shares of capital stock of
any class or series of the Company, so long as such shares were originally
acquired by the FRC Entities from the Company.

401(K) PLAN

     The Company has offered its employees an employee 401(k) savings plan (the
"401(k) Plan"), which became effective upon inception of the Company. The
401(k) Plan covers all employees and entitles each to contribute up to 15% of
his or her annual compensation subject to maximum limitations imposed by the
Internal Revenue Code. The 401(k) Plan allows for employer matching of up to 8%
of the employee's contributions based on years of participation in the plan,
including years of participation in the 401(k) plan previously offered by
Tenneco.

LIMITATION OF DIRECTORS' LIABILITY; INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Company's Certificate of Incorporation provides that no director of the
Company shall be liable to the Company or its stockholders for monetary damages
for breach of fiduciary duty or the duty of care as a director, except for
liability for breach of the director's duty of loyalty, acts not in good faith,
intentional misconduct or knowing violations of law, unlawful payment of
dividends or stock purchases or redemptions, or transactions in which the
director derived an improper personal benefit. The Certificate of Incorporation
also provides for the indemnification of officers and directors to the fullest
extent permitted by Delaware law. The Company also maintains directors' and
officers' liability insurance coverage.

     Generally, Section 145 of the Delaware General Corporation Law, as amended
(the "DGCL"), provides that a corporation may indemnify any person who is or
was a party or is threatened to be made a party to any threatened, pending or
completed action, including any action by or in the right of the corporation
(unless such person was adjudged liable to the corporation, in which event
indemnification is permitted if, but only to the extent that, the court in which
such action was brought determined such indemnification is fair and reasonable)
by reason of the fact that such person is or was a director, officer, employee
or agent of the corporation, or is or was serving in such capacity for another
corporation or entity

                                       61
<PAGE>
at the request of the corporation, if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Such indemnification may
include all expenses (including attorneys' fees) and, in the case of any action
other than an action by or in the right of the corporation, all judgments, fines
and amounts paid in settlement, to the extent such expenses, judgments, fines
and amounts were actually paid and reasonably incurred by the indemnified party
in connection with such action.

                              CERTAIN TRANSACTIONS

SECURITYHOLDERS AGREEMENT

     The Company, Fund VII and the Company's officers who have purchased Common
Stock (the "Management Investors") are parties to Securityholders Agreement
dated as of December 31, 1996 (the "Securityholders Agreement"). The
Securityholders Agreement contains provisions governing the management of the
Company, voting of shares, election of directors and restrictions on transfer of
shares, all of which terminate automatically upon the completion of the
Offering. In addition, the Securityholders Agreement provides Fund VII, after
the Offering, the right on four occasions to require the Company to register all
or part of Fund VII's registrable shares of Common Stock under the Securities
Act, and the Company is required to use its reasonable best efforts to effect
such registration, subject to certain conditions and limitations. Upon the
Company's receipt of a demand from Fund VII to register all or part of its
registrable shares, the Company is required to notify the other parties to the
Securityholders Agreement of the demand, and such parties shall, subject to
certain conditions and limitations, have the right to include the registrable
shares held by them in such registration. The Securityholders Agreement also
provides all the parties thereto with piggyback registration rights on any
offering by the Company of any of its securities to the public except a
registration on Forms S-4 or S-8 under the Securities Act; provided, however,
that until two years after the date of the Offering, the Management Investors
will not have piggyback registration rights with respect to any registration in
which Fund VII or any of its permitted transferees are not participating. The
Company will bear the expenses of all registrations under the Securityholders
Agreement. Fund VII has waived its registration rights with respect to a
Registration Statement filed by the Company with respect to the Offering.

MANAGEMENT INVESTOR SUBSCRIPTION AGREEMENTS AND RELATED TRANSACTIONS

     Shortly before the Offering, each of the Management Investors entered into
a Management Investor Subscription Agreement with the Company pursuant to which
the Management Investors purchased an aggregate of 390,311 shares of Common
Stock. To facilitate such purchases, the Company loaned the Management Investors
the following amounts: (i) Mr. Ronca ($249,200), (ii) Mr. Newhouse ($87,000),
(iii) Ms. Sliva ($35,445), (iv) Mr. Lester ($50,011), (v) Mr. Woodul ($49,763),
(vi) Mr. Curran ($50,376) and (vii) Ms. Herrin ($24,231). All such indebtedness
of such persons accrues interest at the rate of 8% per annum, payable
semiannually; provided that each Management Investor may elect to satisfy his or
her semiannual interest payment obligation by increasing the principal amount of
the indebtedness owed to the Company by the amount of interest otherwise
payable. As security for such loans made by the Company, each Management
Investor pledged to the Company, and granted a first priority security interest
in, the shares of Common Stock purchased by such Management Investor pursuant to
its respective Management Investor Subscription Agreement and is required to
pledge, and grant a first priority security interest in, all other shares of
Common Stock that each such person may subsequently acquire, including, without
limitation, upon exercise of options to purchase shares of Common Stock. As of
March 31, 1997, the outstanding indebtedness of each Management Investor to the
Company was equal to the original principal amount loaned to such Management
Investor as indicated above plus interest accrued thereon.

INDEBTEDNESS TO FUND VII

     Prior to the Acquisition, Tennessee Gas Pipeline Company ("TGPL"), the
former wholly-owning parent of Ventures Corporation, was a guarantor with
respect to certain indebtedness (the "Michigan Senior

                                       62
<PAGE>
Debt") of a partnership formed to participate in the Michigan Development
Project in which Ventures Corporation was at the time a general partner. In
connection with the Acquisition, the Company formed Domain Energy Guarantor
Corporation, a Delaware corporation ("Guarantor Corporation"), for the sole
purpose of assuming the obligations of TGPL under such guaranty. As security for
its obligations under the guaranty, Guarantor Corporation purchased an $8.0
million certificate of deposit issued by the lender in respect of the Michigan
Senior Debt and assigned and pledged such certificate to the lender.

     To enable Guarantor Corporation to purchase the $8.0 million certificate
pledged as collateral for its guaranty of the Michigan Senior Debt, Fund VII
loaned Guarantor Corporation $8.0 million evidenced by a Subordinated Promissory
Note dated December 31, 1996 (the "Note"). The full principal amount of the
Note matures on December 31, 1999. Interest accrues on the Note at a rate per
annum equal to the interest rate per annum earned by Guarantor Corporation on
the $8.0 million certificate and is payable quarterly. The obligations of
Guarantor Corporation under the Note are expressly made subordinate and subject
in right of payment to the prior payment in full of the Michigan Senior Debt.
Upon consummation of the Michigan Disposition, the Michigan Senior Debt will be
repaid in full and the pledge of the $8.0 million certificate will be released.

FUND VII OPTION TO ACQUIRE COMMON STOCK

     Pursuant to the Subscription Agreement dated December 31, 1996 (the "First
Reserve Subscription Agreement"), between the Company and Fund VII, the Company
granted to Fund VII an option (the "First Reserve Option") to acquire
1,914,048 shares of Common Stock for an aggregate purchase price of $8.0 million
plus any cash interest payment on the Note actually received by Fund VII (the
"Option Price"). The Option Price may be paid by Fund VII (i) prior to the
date on which the Note has been paid in full, by delivery to the Company of the
Note together with the payment in cash of any principal or interest payments on
the Note previously received by Fund VII and (ii) after the date on which the
Note has been paid in full, by payment of the Option Price in cash. Fund VII has
irrevocably waived its right to exercise the First Reserve Option effective upon
consummation of the Offering. The Note will be repaid in full upon consummation
of the Offering with the proceeds of the liquidation of the $8.0 million
certificate pledged as collateral by Guarantor Corporation for its guaranty of
the Michigan Senior Debt.

FIRST RESERVE TRANSACTION FEE

     In connection with the Acquisition, the Company agreed to pay First Reserve
a fee of $500,000. First Reserve has irrevocably waived its right to receive
this fee effective upon consummation of the Offering.

    Corporation and may therefore be deemed to share beneficial ownership of the
    shares shown as beneficially owned by First Reserve Corporation. Mr. Linker
    is the sole stockholder of an entity that is a limited partner of Fund VII
    and may therefore be deemed to have beneficial ownership of the shares shown

    and Linker disclaim beneficial ownership of such shares.

                          DESCRIPTION OF CAPITAL STOCK

     THE FOLLOWING SUMMARY DESCRIPTION OF THE COMPANY'S CAPITAL STOCK IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE COMPANY'S CERTIFICATE OF
INCORPORATION, A COPY OF WHICH HAS BEEN INCLUDED AS AN EXHIBIT TO THE
REGISTRATION STATEMENT OF WHICH THIS PROSPECTUS IS A PART. ALL CAPITALIZED TERMS
USED AND NOT DEFINED BELOW HAVE THE RESPECTIVE MEANINGS ASSIGNED TO THEM IN THE
CERTIFICATE OF INCORPORATION.

COMMON STOCK

     The Company is authorized to issue up to 25,000,000 shares of Common Stock,
$.01 par value per share. As of the date of this Prospectus, there were
7,663,695 shares of Common Stock issued and outstanding. Immediately after
completion of the Offering, 13,663,695 shares of Common Stock will be issued and
outstanding.

     Holders of Common Stock are entitled to one vote for each share held, are
not entitled to cumulative voting for the purpose of electing directors and have
no preemptive or similar right to subscribe for, or to purchase, any shares of
Common Stock or other securities to be issued by the Company in the future.
Accordingly, the holders of more than 50% in voting power of the shares of
Common Stock voting generally for the election of directors will be able to
elect all of the Company's directors. Immediately after completion of the
Offering, Fund VII will own 52.5% of the outstanding shares of Common Stock of
the Company (or 49.3% if the over-allotment option is exercised in full) and
will be in a position to control actions that require the consent of
stockholders, including the election of directors, payment of dividends,

                                       64
<PAGE>
amendment of the Certificate of Incorporation and mergers or a sale of
substantially all of the assets of the Company.

     Holders of shares of Common Stock have no exchange, conversion or
preemptive rights and such shares are not subject to redemption. All outstanding
shares of Common Stock are, and upon issuance the shares of Common Stock offered
hereby will be, duly authorized, validly issued, fully paid and nonassessable.
Subject to the prior rights, if any, of holders of any outstanding class or
series of capital stock having a preference in relation to the Common Stock as
to distributions upon the dissolution, liquidation and winding-up of the Company
and as to dividends, holders of Common Stock are entitled to share ratably in
all assets of the Company which remain after payment in full of all debts and
liabilities of the Company, and to receive ratably such dividends, if any, as
may be declared by the Company's Board of Directors from time to time out of
funds and other assets legally available therefor. See "Dividend Policy" and
"Capitalization."

PREFERRED STOCK

     The Board of Directors is authorized, without action by the holders of
Common Stock, to issue up to 5,000,000 shares of preferred stock, $.01 par value
(the "Preferred Stock"), in one or more series, to establish the number of
shares to be included in each such series and to fix the designations,
preferences, relative, participating, optional and other special rights of the
shares of each such series and the qualifications, limitations and restrictions
thereof. Such matters may include, among others, voting rights, conversion and
exchange privileges, dividend rates, redemption rights, sinking fund provisions
and liquidation rights that could be superior and prior to the Common Stock.

     The issuance of one or more series of the Preferred Stock could, under
certain circumstances, adversely affect the voting power of the holders of the
Common Stock and could have the effect of discouraging or making more difficult
any attempt by a person or group to effect a change in control of the Company.

DELAWARE BUSINESS COMBINATION STATUTE

     The Company is a Delaware corporation and is subject to Section 203 of the
DGCL ("Section 203"). In general, Section 203 prevents an "interested
stockholder" (defined generally as a person owning 15% or more of a
corporation's outstanding voting stock) from engaging in a "business
combination" (as therein defined) with a Delaware corporation for three years
following the time that such person became an interested stockholder, unless (i)
before such person became an interested stockholder, the board of directors of
the corporation approved the business combination in question or the transaction
which resulted in such person becoming an interested stockholder, (ii) upon
consummation of the transaction that resulted in the interested stockholder's
becoming such, the interested stockholder owns at least 85% of the voting stock
of the corporation outstanding at the time such transaction commenced (excluding
stock held by directors who are also officers of the corporation and by employee
stock plans that do not provide employees with rights to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer), or (iii) at or following the transaction in which
such person became an interested stockholder, the business combination is
approved by the board of directors of the corporation and authorized at a
meeting of stockholders by the affirmative vote of the holders of not less than
66 2/3% of the outstanding voting stock of the corporation not owned by the
interested stockholder. Under Section 203, the restrictions described above do
not apply to certain business combinations proposed by an interested stockholder
following the announcement (or notification) of one of certain extraordinary
transactions involving the corporation and a person who had not been an
interested stockholder during the preceding three years or who became an
interested stockholder with the approval of the corporation's directors or at a
time when the restrictions imposed by Section 203 did not apply in accordance
with the terms thereof, and which transactions are approved or not opposed by a
majority of the members of the board of directors then in office who were
directors prior to any person becoming an interested stockholder during the
previous three years or were recommended for election or elected to succeed such
directors by a majority of such directors. Fund VII is not subject to the
restrictions contained in Section 203 because the transaction that resulted in
Fund VII becoming an interested stockholder (i.e., the sale of shares of Common
Stock to Fund

                                       65

VII to finance the Acquisition pursuant to the First Reserve Subscription
Agreement) was approved by the Board of Directors.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Upon completion of the Offering, the Company will have outstanding an
aggregate of 13,663,695 shares of Common Stock. All of the 6,000,000 shares sold
in the Offering (6,900,000 shares if the over-allotment option granted to the
Underwriters is exercised in full) will be freely tradeable without restriction
or further registration under the Securities Act, except for any shares
purchased by "affiliates" of the Company, as that term is defined in Rule 144
under the Securities Act (whose sales would be subject to certain limitations
and restrictions described below).

     The 7,663,695 shares of Common Stock held by the Company's existing
stockholders were issued and sold by the Company in reliance on an exemption
from the registration requirements of the Securities Act. The outstanding shares
of Common Stock held by such stockholders after the Offering will be subject to
the "lock-up" agreement described below. After expiration of such lock-up
agreement 180 days after the date of this Prospectus, the Common Stock then
owned by such stockholders may be resold only upon registration under the
Securities Act or pursuant to an exemption from such registration requirements,
including exemptions contained in Rule 144. The Securityholders Agreement
provides Fund VII, after the Offering, the right on four occasions to require
the Company to register all or part of Fund VII's registrable shares of Common
Stock under the Securities Act, and the Company is required to use its
reasonable best efforts to effect such registration, subject to certain
conditions and limitations. Upon the Company's receipt of a demand from Fund VII
to register all or part of its registrable shares, the Company is required to
notify the other parties to the Securityholders Agreement of the demand and such
parties shall, subject to certain conditions and limitations, have the right to
include the registrable shares held by them in such registration. The
Securityholders Agreement also provides all the parties thereto with piggyback
registration rights on any offering by the Company of any of its securities to
the public except a registration on Forms S-4 or S-8 under the Securities Act;
provided, however, that until two years after the date of the Offering, the
Management Investors will not have piggyback registration rights with respect to
any registration in which Fund VII or any of its permitted transferees are not
participating. Fund VII has waived its registration rights with respect to a
Registration Statement filed by the Company with respect to the Offering and has
informed the Company that it has no immediate plans to sell or otherwise dispose
of shares of the Common Stock.

     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares of a public
company for at least two years (including the holding period of any prior owner
except an affiliate) that were not acquired in a public offering is entitled to
sell in "broker's transactions" or to market makers, within any three-month
period, a number of shares that does not exceed the greater of (i) 1% of the
number of shares of Common Stock then outstanding (approximately 136,636 shares
immediately after the Offering) or (ii) generally, the average weekly trading
volume in the Common Stock during the four calendar weeks preceding the required
filing of a Form 144 with respect to such sale. Sales under Rule 144 are
generally subject to the availability of current public information about the
Company. Under Rule 144(k), a person who is not deemed to have been an affiliate
of the Company at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least three years, is
entitled to sell such shares without having to comply with the manner of sale,
public information, volume limitation or notice filing provisions of Rule 144.
Effective as of April 29, 1997, the holding period requirements contained in
Rule 144 have been changed from two years and three years to one year and two
years, respectively.

     As soon as practicable following the Offering, the Company intends to file
a registration statement on Form S-8 under the Securities Act covering 867,100
shares of Common Stock reserved for issuance pursuant to its Stock Purchase and
Option Plan. Shares of Common Stock issued upon exercise of the stock

                                       66
<PAGE>
options granted under the Stock Purchase and Option Plan after the effective
date of such registration statement will be freely tradeable, except for any
such shares acquired by an "affiliate" of the Company, as that term is defined
in Rule 144 under the Securities Act.

     The Company, each of the Company's directors and executive officers and
Fund VII have agreed not to sell, offer to sell, contract to sell, grant any
option for the sale of or otherwise dispose of, directly or indirectly, any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for any Common Stock owned by any of them prior to the expiration
of 180 days from the date of this Prospectus, except (i) for shares of Common
Stock offered hereby, (ii) with the prior written consent of PaineWebber
Incorporated, and (iii) for the issuance of shares pursuant to employee benefit
plans of the Company, provided that the Company has agreed not to grant options
to purchase shares of Common Stock at a price less than the Offering price.

     Prior to the Offering, there has been no public market for the Common
Stock, and no prediction can be made as to the effect, if any, that future sales
of shares or the availability of shares for sale will have on the market price
for Common Stock prevailing from time to time. Sales of substantial amounts of
Common Stock in the public market, or the perception of the availability of
shares for sale, could adversely affect the prevailing market price of the
Common Stock and could impair the Company's ability to raise capital through the
sale of its equity securities.

                                  UNDERWRITING

     Subject to the terms and conditions set forth in the Underwriting Agreement
(the "Underwriting Agreement"), the Company has agreed to sell to each of the
Underwriters named below (the "Underwriters"), and each of the Underwriters,
for whom PaineWebber Incorporated, Prudential Securities Incorporated, and
Morgan Keegan & Company, Inc. are acting as Representatives (the
"Representatives"), has severally agreed to purchase from the Company, the
respective number of shares set forth opposite their names below:

                                            NUMBER
              UNDERWRITER                  OF SHARES
- ----------------------------------------   ---------
PaineWebber Incorporated................

Morgan Keegan & Company, Inc............

                                           ---------
     Total..............................   6,000,000
                                           =========

     The Underwriting Agreement provides that the obligations of the
Underwriters to purchase the shares of Common Stock listed above are subject to
certain conditions. The Underwriting Agreement also provides that the
Underwriters are committed to purchase, and the Company is obligated to sell,
all of the shares of Common Stock offered by this Prospectus, if any of the
shares of Common Stock being sold pursuant to the Underwriting Agreement are
purchased (without consideration of any shares that may be purchased through the
exercise of the Underwriters' over-allotment option).

     The Representatives have advised the Company that the Underwriters propose
to offer the shares of Common Stock to the public initially at the public
offering price set forth on the cover page of this Prospectus and to certain
dealers at such price less a concession not in excess of $     per share. The
Underwriters may allow, and such dealers may reallow, a concession to other
dealers not in excess of $     per share. After the initial public offering of
the shares of the Common Stock, the public offering

                                       67
<PAGE>
price, the concessions to selected dealers and the reallowance to other dealers
may be changed by the Representatives.

     The Company has granted to the Underwriters an option, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to an
additional 900,000 shares of Common Stock at the initial public offering price
set forth on the cover page of this Prospectus, less the underwriting discounts
and commissions. The Underwriters may exercise such option only to cover
over-allotments, if any, incurred in the sale of shares of Common Stock. To the
extent the Underwriters exercise such option, each of the Underwriters will
become obligated, subject to certain conditions, to purchase such percentage of
such additional shares of Common Stock as is approximately equal to the
percentage of shares of Common Stock that it is obligated to purchase as shown
in the table set forth above.

     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.

     The Representatives have informed the Company that they do not intend to
confirm sales to any account over which they exercise discretionary authority.

     The Company, each of the Company's directors and executive officers and
Fund VII have agreed not to sell, offer to sell, contract to sell, grant any
option for the sale of or otherwise dispose of, directly or indirectly, any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for any Common Stock owned by any of them prior to the expiration
of 180 days from the date of this Prospectus, except (i) for shares of Common
Stock offered hereby, (ii) with the prior written consent of PaineWebber
Incorporated and (iii) for the issuance of shares pursuant to employee benefit
plans of the Company, provided that the Company has agreed not to grant options
to purchase shares of Common Stock at a price less than the Offering price.

     Prior to the Offering, there has been no public market for the Common
Stock. The initial public offering price will be determined pursuant to
negotiations among the Company, First Reserve, and the Representatives. Among
the factors to be considered in determining the initial public offering price,
in addition to prevailing market conditions, will be certain financial
information of the Company, the history of, and the prospects for, the Company
and the industry in which it competes, an assessment of the Company's
management, its past and present operations, the prospects for, and timing of,
future revenues of the Company, the present state of the Company's development,
and the above facts in relation to market values and various valuation measures
of other companies engaged in activities similar to the Company. The initial
public offering price set forth on the cover page of this Prospectus should not,
however, be considered an indication of the actual value of the Common Stock.
Such price is subject to change as a result of market conditions and other
factors. There can be no assurance that an active trading market will develop
for the Common Stock or that the Common Stock will trade in the public market
subsequent to the Offering at or above the initial public offering price.

     In connection with the Acquisition, the Company paid PaineWebber
Incorporated a fee of $2.1 million for financial advisory services.

     In connection with this Offering, certain Underwriters and selling group
members and their respective affiliates may engage in transactions that
stabilize, maintain or otherwise affect the market price of the Common Stock.
Such transactions may include stabilization transactions effected in accordance
with Rule 104 of Regulation M, pursuant to which such persons may bid for or
purchase Common Stock for the purpose of stabilizing its market price. The
Underwriters also may create a short position for the account of the
Underwriters by selling more Common Stock in connection with the Offering than
they are committed to purchase from the Company and the Selling Stockholders,
and in such case may purchase Common Stock in the open market following
completion of the Offering to cover all or a portion of such short position. The
Underwriters may also cover all or a portion of such short position, up to
900,000 shares of Common Stock, by exercising the Underwriters' over-allotment
option referred to above. In addition, PaineWebber Incorporated, on behalf of
the Underwriters, may impose "penalty bids" under contractual arrangements
with the Underwriters whereby it may reclaim from an Underwriter (or dealer
participating in the Offering)

                                       68
<PAGE>
for the account of the other Underwriters, the selling concession with respect
to Common Stock that is distributed in the Offering but subsequently purchased
for the account of the Underwriters in the open market. Any transactions
described in this paragraph may result in the maintenance of the price of the
Common Stock at a level above that which might otherwise prevail in the open
market. None of the transactions described in this paragraph is required, and,
if they are undertaken, they may be discontinued at any time.

     Application will be made for approval for listing of the Common Stock on
the New York Stock Exchange. In connection with the possibility of the listing
of the Common Stock on the New York Stock Exchange, the Underwriters have
undertaken to sell round lots of 100 shares or more to a minimum of 2,000
beneficial owners.

                                 LEGAL MATTERS

     The validity of the shares of Common Stock offered hereby will be passed on
for the Company by Weil, Gotshal & Manges LLP, Houston, Texas and for the
Underwriters by Baker & Botts, L.L.P., Houston, Texas.

                          INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders of
  Domain Energy Corporation

We have audited the accompanying consolidated balance sheet of Domain Energy
Corporation and subsidiaries (the "Company"), the Successor, as of December
31, 1996 and the accompanying combined balance sheet of Tenneco Ventures
Corporation and Tenneco Gas Production Corporation (the "Tenneco Entities"),
the Predecessor, as of December 31, 1995 and the related combined statements of
income, stockholder's equity and cash flows for each of the three years in the
period ended December 31, 1996. 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, such financial statements present fairly, in all material
respects, the consolidated financial position of the Company and its
subsidiaries as of December 31, 1996 and the combined financial position of the
Tenneco Entities as of December 31, 1995 and the combined results of their
operations and their combined cash flows for each of the three years in the
period ended December 31, 1996 in conformity with generally accepted accounting
principles.

            NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS

1.  ORGANIZATION, BASIS OF PRESENTATION AND NATURE OF OPERATIONS

     For the years ended December 31, 1994 and 1995 and for the period from
January 1, 1996 through December 11, 1996, Tenneco Ventures Corporation
("Ventures") and Tenneco Gas Production Corporation ("Production" and,
together with Ventures, the "Tenneco Entities") were indirect subsidiaries of
Tenneco, Inc. ("Tenneco"). As a result of a merger between Tenneco and a
subsidiary of El Paso Natural Gas Company ("El Paso"), Ventures and Production
became wholly owned indirect subsidiaries of El Paso for the period from
December 12, 1996 to December 31, 1996. On December 31, 1996, Domain Energy
Corporation ("Domain") acquired all of the outstanding common stock of
Ventures and Production (the "Acquisition"). Domain was incorporated in
Delaware in December 1996 to acquire such common stock and had no operations
prior to the Acquisition.

     Unless otherwise indicated, references to the Company are to Domain and its
subsidiaries at and subsequent to December 31, 1996 and to the combined
activities of the Tenneco Entities prior to December 31, 1996. References to the
Parent are to Tenneco or its affiliates prior to December 11, 1996 and to El
Paso from December 12, 1996 to December 31, 1996.

     The Company was capitalized on December 31, 1996 with the issuance of
9,519.4717 shares of common stock for $30.0 million and borrowings of $66.2
million under its credit facilities. The Company completed the Acquisition for a
total cash purchase price of approximately $95.8 million and the assumption of
liabilities of approximately $31.2 million. The Company has accounted for the
Acquisition using the purchase method of accounting. The assets and liabilities
of the Tenneco Entities have been recorded in the Company's balance sheet at
December 31, 1996 at their estimated fair market values, summarized as follows
(in thousands):.

ASSETS:
     Accounts receivable -- trade....  $   13,404
     IPF Program notes receivable....      21,710

     The financial statements of the Tenneco Entities at December 31, 1995 and
for each of the years ended December 31, 1994, 1995 and 1996 have been combined
to reflect their combined historical financial position and historical results
of operations.

     The following unaudited pro forma summary presents the consolidated results
of operations of the Company for the years ended December 31, 1995 and 1996 as
if the Acquisition had occurred at the beginning of 1995 (in thousands):

     NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
Program") pursuant to which it invests in oil and natural gas reserves through
the acquisition of term overriding royalty interests.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION AND COMBINATION -- The consolidated balance
sheet at December 31, 1996 includes the accounts of the Company and its
majority-owned subsidiaries. The combined financial statements of the Tenneco
Entities include their combined accounts and the combined accounts of their
majority-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.

     OIL AND GAS PROPERTIES -- Investments in oil and gas properties are
accounted for using the full cost method of accounting. All costs associated
with the acquisition, exploration, exploitation and development of oil and gas
properties are capitalized.

     Oil and gas properties are amortized using the unit-of-production method
using estimates of proved reserve quantities. Investments in unproved properties
are not amortized until proved reserves associated with the projects can be
determined or until impairment occurs. If the results of the assessment indicate
that the properties are impaired, the amount of impairment is added to the
proved oil and gas property costs to be amortized. The amortizable base includes
future development costs and, where significant, dismantlement, restoration, and
abandonments costs, net of estimated salvage values. The depletion rate per Mcfe
for the years ended December 31, 1994, 1995 and 1996 was $1.03, $1.08 and $0.91,
respectively.

     Sales of proved and unproved properties are accounted for as adjustments of
capitalized costs with no gain or loss recognized, unless such adjustments would
significantly alter the relationship between capitalized costs and proved
reserves. Abandonments of properties are accounted for as adjustments of
capitalized costs with no loss recognized.

     In addition, the total capitalized costs of oil and gas properties are
subject to a "ceiling test", which limits such costs to the estimated present
value, discounted at a 10% interest rate, of future net cash flows from proved
reserves, based on current economic and operating conditions, plus the cost of
unproved prospects. If capitalized costs exceed this limit, the excess is
charged to depreciation, depletion and amortization.

     INDEPENDENT PRODUCER FINANCE PROGRAM -- Through its IPF Program, the
Company acquires term overriding royalty interests in oil and gas properties
owned by independent producers. Because the funds advanced to a producer for
these interests are repaid from an agreed upon share of cash proceeds from the
sale of production until the amount advanced plus interest is paid in full, the
Company accounts for the term overriding royalty interests as notes receivable.
Under this accounting method, the Company recognizes only the interest income
portion of payments received from a producer as revenues on its income
statement. The remaining cash receipts are recorded as a reduction in notes
receivable on the Company's balance sheet and as IPF Program return of capital
on the Company's statement of cash flows. The Company records an impairment for
its investments on a case-by-case basis when it determines repayment to be
doubtful.

     INCOME TAXES -- Through December 31, 1996, the Company's taxable income is
included in a consolidated United States income tax return with the Parent. The
intercompany tax allocation policy between the Company and the Parent provided
that each member of the consolidated group compute a provision for income taxes
on a separate return basis. The Company records its income taxes utilizing an
asset and liability approach which requires recognition of deferred tax assets
and liabilities for the expected future tax consequences of temporary
differences between the book carrying amounts and the tax basis of assets and
liabilities. All current amounts due to or from the Parent are included in
Parent advances on the combined balance sheet.

     OIL AND GAS HEDGING ACTIVITIES -- The Company periodically uses derivative
financial instruments to manage price risks related to oil and natural gas sales
and not for speculative purposes. For book purposes,

     NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
gains and losses related to the hedging of anticipated transactions are
recognized as income when the hedged transaction occurs.

     The Company primarily utilizes price swap agreements with major energy
companies to accomplish its hedging objectives. The price swap agreements
generally provide for the Company to receive or make counter-party payments on
the differential between a fixed price and a variable indexed price. Total oil
and natural gas sales hedged during the years ended December 31, 1996 and 1995
were 258,710 Bbls and 16,025 MMcf and 65,840 Bbls and -0- MMcf, respectively.
There were no hedging transactions in 1994. Gains (losses) realized by the
Company under such hedging arrangements, and reported as an increase (reduction)
of revenues, were ($10.5 million) and $0.2 million for the years ended December
31, 1996 and 1995, respectively. The following table sets forth the Company's
open hedging contracts for oil and natural gas under various price swap
agreements with major energy companies as of December 31, 1996:

</TABLE>
     REVENUE RECOGNITION -- The Company recognizes oil and gas revenue from its
interests in producing wells as oil and gas is produced from those wells. Oil
and gas sold in production operations is not significantly different from the
Company's share of production. The Company recognizes financing revenues from
its producer financing activities using the effective interest rate method.

     The Company utilizes the sales method to account for gas production volume
imbalances. Under this method, income is recorded based on the Company's net
revenue interest in production taken for delivery. Management does not believe
that the Company had any material natural gas imbalances at December 31, 1996 or
1995.

     FINANCIAL INSTRUMENTS -- The Company's financial instruments consist of
cash, accounts and notes receivable, payables, long-term debt and oil and
natural gas commodity hedges. The carrying amount of cash, accounts receivable
and payables approximates fair value because of the short-term nature of these
items. Based on current industry and other conditions, management believes that
the carrying value of its IPF Program notes receivable approximates, at a
minimum, their fair value. The carrying value of long-term debt approximates
fair value because the individual borrowings bear interest at floating market
rates. Assuming a market price based on the twelve-month strip as of December
31, 1996, the Company's projected losses from these open hedge contracts was
approximately $2.7 million as of December 31, 1996. Considerable judgment is
required in developing these estimates and, accordingly, no assurance can be
given that the estimated values presented herein are indicative of amounts that
would be realized in a full market exchange.

     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 and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses during
the reporting periods. Actual results could differ from these estimates.
Significant estimates include depreciation, depletion and amortization of proved
producing oil and natural gas properties; estimates of proved oil and natural
gas reserve volumes; and discounted future net cash flows.

     CONCENTRATION OF RISK -- Substantially all of the Company's accounts and
notes receivable result from oil and natural gas sales, joint interest billings
and lending activities to third parties in the oil and natural gas industry.
This concentration of customers, joint interest owners and borrowers may impact
the Company's

     NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
overall credit risk in that these entities may be similarly affected by changes
in economic and other conditions. Historically, the Company has not experienced
credit losses on such accounts and notes receivable.

     STATEMENTS OF CASH FLOWS -- The statements of cash flows are presented
using the indirect method and consider all highly liquid investments with
maturities at the time of purchase of three months or less to be cash
equivalents.

     Supplemental cash flow information may be summarized as follows (in
thousands):

     Liabilities assumed.............      --          --          31,200

     EMPLOYEE STOCK-BASED COMPENSATION -- In October 1995, Financial Accounting
Standards Board Statement No. 123, "Accounting for Stock Based Compensation"
("SFAS 123") was issued. Under SFAS No. 123, the Company is permitted to
either record expenses for stock options and other stock-based employee
compensation plans based on their fair value at the date of grant or to apply
the existing standard, Accounting Principles Board Opinion No. 25 ("APB 25")
and recognize compensation expense, if any, based on the intrinsic value of the
equity instrument at the measurement date. The Company has elected to continue
to follow APB 25. When applicable, the Company will disclose pro forma net
income and earnings per share computed as if the Company utilized SFAS 123.

3.  NOTES RECEIVABLE -- INDEPENDENT PRODUCER FINANCING

     At December 31, 1996 and 1995, the Company had total outstanding notes
receivable related to its IPF Program of $21.7 million and $8.0 million,
respectively. The notes receivable result from the Company's purchase of a
production payment in the form of a term overriding royalty interest in exchange
for an agreed upon share of revenues from identified properties until the amount
invested and a specified rate of return on investment is paid in full. While the
independent producer's obligation to deliver such revenues is nonrecourse to the
producer, management believes that the Company's overriding royalty interest
constitutes a property interest and therefore, such property interest and the
underlying oil and gas reserves effectively serves as security for the notes
receivable. Based on reserve data available, the Company has estimated that $7.9
million and $2.2 million of notes receivable at December 31, 1996 and 1995 will
be repaid in the next twelve months and has classified such amounts as current
assets.

4.  UNEVALUATED PROPERTY

     Oil and natural gas properties not subject to amortization consist of the
cost of undeveloped leaseholds, exploratory and developmental wells in progress,
and secondary recovery projects before the assignment of proved reserves. These
costs are reviewed periodically by management for impairment, with the
impairment provision included in the cost of oil and natural gas properties
subject to amortization. Factors considered by management in its impairment
assessment include drilling results by the Company and other operators, the
terms of oil and gas leases not held by production, production response to
secondary recovery activities

                                       =========  ==========

     REVOLVING CREDIT FACILITY -- In connection with the Acquisition, the
Company entered into a $65.0 million revolving credit facility maturing on
December 31, 1999 (the "Revolving Credit Facility") with a group of banks led
by The Chase Manhattan Bank. The Revolving Credit Facility is secured by
approximately 80% of the aggregate value of the Company's oil and gas properties
and substantially all of the Company's other property (other than IPF Program
related properties), including the capital stock of Ventures and Production and
is also guaranteed by Ventures and Production. Amounts available under the
Revolving Credit Facility are subject to a borrowing base with scheduled
redeterminations every six months (and such other redeterminations as the lender
may elect to perform) by the lenders at the lenders' sole discretion and in
accordance with their customary practices and standards in effect from time to
time for reserve-based loans to borrowers similar to the Company. The borrowing
base under the Revolving Credit Facility at December 31, 1996 was $65.0 million.
On December 31, 1997, the Company is required to reduce its outstanding
indebtedness under the Revolving Credit Facility to $43.3 million. In addition,
if at the end of any fiscal quarter of the Company during 1997 the amount then
outstanding thereunder exceeds $43.3 million (as such amount may be adjusted
from time to time pursuant to the Revolving Credit Facility), the Company will
be obligated to prepay the outstanding indebtedness thereunder in an amount
equal to 100% of the Company's "excess cash flow" (as defined therein) for
such fiscal quarter. Excess cash flow is defined to include a portion of the net
proceeds to the Company of the Offering.

     Absent a default or an event of default, borrowings under the Revolving
Credit Facility accrue interest at LIBOR plus a margin of 1.50% to 2.50% per
annum depending on the total amount outstanding or, at the option of the
Company, at the greater of (i) the prime rate and (ii) the federal funds
effective rate plus 0.50%, plus a margin of 0.50% to 1.50% depending on the
total amount outstanding. The Company also

<PAGE>
                           DOMAIN ENERGY CORPORATION
     NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
incurs a quarterly commitment fee ranging from 0.375% to 0.50% per annum on the
average unused portion of the lenders' aggregate commitment depending on the
total amount outstanding. The interest rate on the amounts outstanding at
December 31, 1996 was 8.04%.

     The Revolving Credit Facility contains a number of covenants that, among
other things, restrict the ability of the Company to dispose of assets, incur
additional indebtedness, pay dividends, enter into certain investments or
acquisition, repurchase or redeem capital stock, engage in mergers or
consolidations, or engage in certain transactions with subsidiaries and
affiliates and that will otherwise restrict corporate activities. In addition,
such facility requires the Company to maintain a specified minimum tangible net
worth and to comply with certain prescribed financial ratios. Further, under
such facility, an event of default is deemed to occur if any person, other than
the Company's officers, Fund VII or any other investment fund, the managing
general partner of which is First Reserve, becomes the beneficial owner,
directly or indirectly, of more than 40% of the outstanding shares of Common
Stock.

     IPF COMPANY CREDIT FACILITY -- IPF Company, an indirect wholly-owned
subsidiary of the Company, has a $20.0 million revolving credit facility with
Compass Bank-Houston (the "IPF Company Credit Facility") pursuant to which it
finances a portion of the IPF Program. The IPF Company Credit Facility matures
June 1, 1998 at which time all amounts owed thereunder are due and payable. The
IPF Company Credit Facility is secured by substantially all of IPF Company's oil
and gas term overriding royalty interests, including the notes receivable
generated therefrom. The borrowing base under the facility as of February 28,
1997 was $18.0 million and is subject to a scheduled redetermination by the
lender every six months and such other redeterminations as the lender may elect
to perform each year. Absent a default or an event of default (as defined
therein), borrowings under the IPF Company Credit Facility accrue interest at
LIBOR plus a margin of 2.25% or, at the option of the IPF Company, the prime
rate published in THE WALL STREET JOURNAL.

     The IPF Company Credit Facility contains a number of covenants that, among
other things, restrict the ability of IPF Company to incur additional
indebtedness or grant liens on its properties, guarantee indebtedness of any
other person, dispose of assets, make loans in excess of $100,000 other than in
the ordinary course of its business, issue additional shares of capital stock,
engage in certain transactions with affiliates, enter into any new line of
business or amend certain of its material contracts. In addition, such facility
requires IPF Company to maintain a specified minimum tangible net worth.

     The IPF Company Credit Facility restricts the ability of IPF Company to
dividend cash to its parent, Ventures, or otherwise advance cash to the Company.
At December 31, 1996, IPF Company net assets of approximately $8.0 million were
restricted.

     MICHIGAN SENIOR DEBT -- To finance the Company's Michigan Development
Project, two affiliates of the Company (Michigan Production Company, L.L.C.
("MPC") and Michigan Energy Company, L.L.C. ("MEC")) entered into a $30.0
million Credit Agreement with Bank of America Illinois (the "Bank of America
Facility") in May 1996. As of December 31, 1996, the two companies had
collectively borrowed $11.5 million under the facility. The Company fully
consolidates the activities of MPC, which borrowed $4.6 million of these
advances, and accounts for MEC on the equity based method of accounting. The
Bank of America Facility is secured by the assets of MPC and MEC, but has no
recourse to the assets of the Company. Advances under the facility bear interest
at LIBOR plus 2.0%, or, at the option of the companies, at the higher of (i) the
Bank of America prime rate or (ii) the federal funds rate plus .50%. A
commitment fee of .25% is payable quarterly. Additionally, Bank of America is
entitled to receive a net profits interest from MPC and MEC of 10% until the
bank receives a rate of return of 14%, after which the net profits interests
reduce to 2%. In 1996 the bank received no payments pursuant to the net profits
interests.

     Bank of America will redetermine the borrowing base semi-annually beginning
on September 1, 1997. Certain financial covenants become effective after
September 1, 1997, including the maintenance of (i)

                                      F-12

     NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
tangible net worth in excess of $3.0 million, (ii) a current ratio greater than
1:1, and (iii) cash flow coverage greater than 1:1 until September 1, 1998 and
greater than 3:1 after September 1, 1998.

     INDEBTEDNESS TO FUND VII -- Prior to the Acquisition, Tennessee Gas
Pipeline Company ("TGPL"), the former wholly-owning parent of Ventures, was a
guarantor with respect to certain indebtedness (the "Michigan Senior Debt") of
a partnership formed to participate in a development project in Michigan in
which Ventures was at the time a general partner. In connection with the
Acquisition, the Company formed Domain Energy Guarantor Corporation ("Guarantor
Corporation"), for the sole purpose of assuming the obligations of TGPL under
such guaranty. As security for its obligations under the guaranty, Guarantor
Corporation purchased an $8.0 million certificate of deposit issued by the
lender in respect of the Michigan Senior Debt and assigned and pledged such
certificate to the lender.

     To enable Guarantor Corporation to purchase the $8.0 million certificate
pledged as collateral for its guaranty of the Michigan Senior Debt, First
Reserve Fund VII, Limited Partnership ("Fund VII"), the Company's sole
stockholder at December 31, 1996, loaned Guarantor Corporation $8.0 million
evidenced by a Subordinated Promissory Note dated December 31, 1996 (the
"Note"). The full principal amount of the Note matures on December 31, 1999.
Interest accrues on the Note at a rate per annum equal to the interest rate per
annum earned by Guarantor Corporation on the $8.0 million certificate and is
payable quarterly. The obligations of Guarantor Corporation under the Note are
expressly made subordinate and subject in right of payment to the prior payment
in full of the Michigan Senior Debt. As the Company expects that in 1997 the
Michigan properties will be sold, the Michigan Senior Debt will be repaid, the
restrictions on the certificate of deposit will be removed, and the Note will be
repaid, the Note has been classified at December 31, 1996 as current maturities
of long-term debt.

     WESTSHORE LOAN AGREEMENT -- Effective October 1, 1996, Westshore Processing
Company, L.L.C. ("Westshore") and MPC entered into a non-recourse loan
agreement. This agreement provides term financing from Westshore to MPC for
construction of a 10-inch diameter natural gas pipeline. The note accrues
interest at an annual rate of 5.98%, compounded semi-annually, with all
outstanding principal and interest due and payable on the completion of the
pipeline. The Company at December 31, 1996 had outstanding debt under this
agreement in the amount of $7.7 million.

6.  RELATED PARTY TRANSACTIONS

     GENERAL AND ADMINISTRATIVE EXPENSES -- Prior to the Acquisition, the
Company paid an affiliate of the Parent for various administrative support
services. Included in general and administrative expenses was approximately $1.3
million and $4.8 million for the years ended December 31, 1995 and 1996.

     Prior to the Acquisition, the Parent also advanced various amounts to the
Company for working capital and capital expenditure requirements. The Parent did
not charge the Company any interest expense on the funds utilized by the
Company. The average amounts of advances outstanding from the Parent were
approximately $31.6 million, $107.7 million and $118.5 million for the years
ended December 31, 1994, 1995 and 1996, respectively. A summary of the activity
in the advances from Parent account follows (in thousands):

     NOTES TO COMBINED AND CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In connection with the Acquisition, the Company agreed to pay First Reserve
Corporation ("First Reserve"), the managing partner of Fund VII, a fee of
$500,000. First Reserve has waived its right to receive this fee effective upon
consummation of the Offering.

7.  STOCKHOLDERS' EQUITY

     COMMON STOCK -- Immediately prior to the Offering the Company will be
authorized to issue up to 25,000,000 shares of Common Stock, $.01 par value per
share. As of December 31, 1996, there were 9519.4717 shares of Common Stock
issued and outstanding. Immediately before consummation of the Offering, a
754-for-one stock split will be effected. Holders of Common Stock are entitled
to one vote for each share held and are not entitled to cumulative voting for
the purpose of electing directors and have no preemptive or similar right to
subscribe for, or to purchase, any shares of Common Stock or other securities to
be issued by the Company in the future. Accordingly, the holders of more than
50% in voting power of the shares of Common Stock voting generally for the
election of directors will be able to elect all of the Company's directors.

     PREFERRED STOCK -- Immediately prior to the Offering the Board of Directors
will be authorized, without action by the holders of Common Stock, to issue up
to 5,000,000 shares of preferred stock, $.01 par value per share (the
"Preferred Stock"), in one or more series, to establish the number of shares
to be included in each such series and to fix the designations, preferences,
relative, participating, optional and other special rights of the shares of each
such series and the qualifications, limitations and restrictions thereof. Such
matters may include, among others, voting rights, conversion and exchange
privileges, dividend rates, redemption rights, sinking fund provisions and
liquidation rights that could be superior and prior to the Common Stock. As of
December 31, 1996, no shares of preferred stock were issued and outstanding.

     STOCK PURCHASE AND OPTION PLAN -- The Company recently adopted the Amended
and Restated 1996 Stock Purchase and Option Plan for Key Employees of Domain
Energy Corporation and Affiliates (the "Stock Purchase and Option Plan"). The
Stock Purchase and Option Plan authorizes the issuance of options to acquire up
to 867,100 shares of Common Stock and the Company has reserved 867,100 shares of
Common Stock for issuance in connection therewith. The Stock Purchase and Option
Plan will be administered by the Compensation Committee of the Board of
Directors. Pursuant to the Stock Purchase and Option Plan, the Company may grant
to employees, directors or other persons having a unique relationship with the
Company or its affiliates, singly or in combination, Incentive Stock Options,
Other Stock Options, Stock Appreciation Rights, Restricted Stock, Purchase
Stock, Dividend Equivalent Rights, Performance Units, Performance Shares or
Other Stock-Based Grants, in each case as such terms are defined therein. The
terms of any such grant will be determined by the Compensation Committee and set
forth in a separate grant agreement. The exercise price will be at least equal
to 100% of fair market value of the Common Stock on the date of grant in the
case of Incentive Stock Options and the exercise price of Other Stock Options
will be at least equal to 50% of fair market value of the Common Stock on the
date of grant, provided that options to purchase up to 433,550 shares of Common
Stock may be granted with an exercise price equal to $.01 per share, which is
the par value of the Common Stock. Non-Qualified Stock Options and Other Stock
Options may be exercisable for up to ten years.

     On February 21, 1997 (the "Grant Date"), the Company granted to the
officers of the Company, pursuant to separate Non-Qualified Stock Option
Agreements (collectively the "Stock Option Agreements") between the Company
and each of such persons, options to purchase a total of 754,000 shares of
Common Stock under the Stock Purchase and Option Plan. In addition, the Company
has granted options to purchase an aggregate of 95,702 shares of Common Stock to
other employees of the Company. Under the terms of the Stock Option Agreements,
50% of the options granted to each such person are designated as time options
(collectively, the "Time Options"), with an exercise price equal to $4.18 per
share, and 50%

are designated as performance options (collectively, the "Performance
Options"), with an exercise price equal to $.01 per share. The Time Options
become exercisable as to 20% of the shares of Common Stock subject thereto on
the first anniversary of the Grant Date and are exercisable as to an additional
20% of such shares upon each anniversary of the Grant Date thereafter. The
Performance Options become exercisable at any time following the second
anniversary of the Grant Date, when the Investment Return Hurdle (as such term
is defined) is met; provided that the Performance Options become exercisable as
to 100% of the shares of Common Stock subject thereto on the ninth anniversary
of the Grant Date.

     MANAGEMENT INVESTOR SUBSCRIPTION AGREEMENTS AND RELATED TRANSACTIONS -- On
February 21, 1997, each of the Company's officers (the "Management Investors")
entered into a Management Investor Subscription Agreement with the Company
pursuant to which the Management Investors purchased an aggregate of 390,311
shares of Common Stock at an average price of $4.18 per share. To facilitate
such purchases, the Company loaned the Management Investors an aggregate of
approximately $546,000. All such indebtedness of such persons accrues interest
at the rate of 8% per annum, payable semiannually; provided that each Management
Investor may elect to satisfy his or her semiannual interest payment obligation
by increasing the principal amount of the indebtedness owed to the Company by
the amount of interest otherwise payable. As security for such loans made by the
Company, each Management Investor pledged to the Company, and granted a first
priority security interest in, the shares of Common Stock purchased by such
Management Investor pursuant to its respective Management Investor Subscription
Agreement and is required to pledge, and grant a first priority security
interest in, all other shares of Common Stock that each such person may
subsequently acquire, including, without limitation, upon exercise of options to
purchase shares of Common Stock. In addition, in April 1997, other employees of
the Company purchased 95,702 shares of Common Stock at an average price of $4.18
per share.

     OPTION TO ACQUIRE COMMON STOCK -- Pursuant to the Subscription Agreement,
dated December 31, 1996 (the "First Reserve Subscription Agreement"), between
the Company and Fund VII, the Company granted to Fund VII an option (the "First
Reserve Option") to acquire 1,914,048 shares of Common Stock for an aggregate
purchase price of $8.0 million plus any cash interest payment on the Note (see
Note 5) actually received by Fund VII (the "Option Price"). The Option Price
may be paid by Fund VII (i) prior to the date on which the Note has been paid in
full, by delivery to the Company of the Note together with the payment in cash
of any principal or interest payments on the Note previously received by Fund
VII and (ii) after the date on which the Note has been paid in full, by payment
of the Option Price in cash. Fund VII has waived its right to exercise the First
Reserve Option effective upon consummation of the Offering. The Note will be
paid in full upon consummation of the Offering with the proceeds of the
liquidation of the $8.0 million certificate pledged as collateral by Guarantor
Corporation for its guaranty of the Michigan Senior Debt.

     The following table sets forth a reconciliation of the statutory federal
income tax with the Company's effective taxes allocated by the Parent (in
thousands):

     Deferred income taxes reflect the tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts calculated for income tax purposes.

     The Company's deferred tax liability as of December 31, 1995 was
$13,349,000. This amount represents the temporary difference in the tax and book
basis of the Company's oil and natural gas properties and investments.

     As of December 31, 1996, the Company had no deferred tax liability. As a
result of the Acquisition and the corresponding election made by El Paso and the
Company to step-up the tax basis in the assets acquired, there are no temporary
differences in the carrying amounts of assets and liabilities for financial
reporting and income tax purposes.

9.  COMMITMENTS AND CONTINGENCIES

     From time to time, the Company is a party to certain lawsuits and claims
arising in the ordinary course of business. While the outcome of lawsuits and
claims cannot be predicted with certainty, management does not expect these
matters to have a materially adverse effect on the Company's financial
condition, results of operations or cash flow.

     401(K) PLAN -- Effective December 31, 1996, the Company has offered its
employees an employee 401(k) savings plan (the "401(k) Plan"). The 401(k) Plan
covers all employees and entitles each to contribute up to 15% of his or her
annual compensation subject to maximum limitations imposed by the Internal
Revenue Code. The 401(k) Plan allows for employer matching of up to 8% of the
employee's contributions based on years of participation in the plan, including
years of participation in the 401(k) plan previously offered by Tenneco.

     RESERVES -- Proved reserves are estimated quantities of oil and natural gas
which 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 reserves are proved reserves that can
reasonably be expected to be recovered through existing wells with existing
equipment and operating methods.

     Proved oil and natural gas reserve quantities and the related discounted
future net cash flows before income taxes for the periods presented are based on
estimates prepared by DeGolyer and MacNaughton, Netherland, Sewell & Associates,
Inc., and other third-party independent petroleum engineers. Such estimates have
been prepared in accordance with guidelines established by the Securities and
Exchange Commission.

     The table of Standardized Measure of Discounted Future Net Cash Flows
includes the consolidation of the Michigan properties for 1996. The minority
interest's share of standardized measure of future net cash flows is
approximately $14,400.

     Future cash flows are computed by applying year end prices of oil and
natural gas to year end quantities of proved oil and natural gas reserves.
Future operating expenses and development costs are computed primarily by the
Company's petroleum engineers by estimating the expenditures to be incurred in
developing and producing the Company's proved oil and natural gas reserves at
the end of the year, based on year end costs and assuming continuation of
existing economic conditions.

     Future income taxes are based on year end statutory rates, adjusted for
operating loss carryforwards and tax credits. A discount factor of 10% was used
to reflect the timing of future net cash flows. The standardized measure of
discounted future net cash flows is not intended to represent the replacement
cost or fair market value of the Company's oil and gas properties.

     The standardized measure of discounted future net cash flows does not
purport, nor should it be interpreted, to present the fair value of the
Company's oil and natural gas reserves. An estimate of fair value would also
take into account, among other things, the recovery of reserves not presently
classified as

SCOPE OF INVESTIGATION

     This report presents an appraisal, as of December 31, 1996, of the extent
and value of the proved crude oil, condensate, and natural gas reserves of
certain property interests owned by (i) Domain Energy Ventures Corporation
(Domain), (ii) the Matrix Limited Partnership owned by Domain, and (iii) Domain
Energy Production Corporation through the Investment Fund I (DEPC Fund I) and
the Investment Fund II (DEPC Fund II). DEPC Fund I is composed of four
investors, one of which is Domain Energy Corporation. Domain Energy Corporation
is the managing partner for DEPC Fund I and its ownership interest is 10 percent
of the total working interest owned by DEPC Fund I. The other investors
participate as net profits interest owners in the remaining 90 percent of the
total working interest taken by DEPC Fund I. The interests evaluated herein are
the total of Domain Energy Corporation's 10 percent and the 90 percent owned by
the other three Participants in DEPC Fund I. DEPC Fund II is composed of four
investors, one of which is Domain Energy Corporation. Domain Energy Corporation
is the managing partner for DEPC Fund II and its ownership interest is 30
percent of the total working interest owned by DEPC Fund II. The other investors
participate as net profits interest owners in the remaining 70 percent of the
total working interest taken by DEPC Fund II. The interest evaluated herein are
the total of Domain Energy Corporation's 30 percent and the 70 percent owned by
the other three participants in DEPC Fund II. Those properties consist of
certain productive leasehold interests located in Alabama, Louisiana,
Mississippi, and Texas and offshore from Alabama, Louisiana, and Texas.

     This report estimates values for proved reserves using initial prices and
costs based on data provided by Domain with no increases in the future based on
inflation. A detailed explanation of the future price and cost assumptions is
included in the Valuation of Reserves section of this report.

     Reserves estimated in this report are expressed as gross and net reserves.
Gross reserves are defined as the total estimated petroleum remaining to be
produced from these properties after December 31, 1996. Net reserves are defined
as that portion of the gross reserves attributable to the interests of Domain,
DEPC Fund I, or DEPC Fund II after deducting royalties and interests owned by
others.

     Values of the net reserves in this report are expressed in terms of
estimated future gross revenue, future net revenue, and present worth. Future
gross revenue is that revenue which will accrue from the production and sale of
the estimated production taxes, operating expenditures, and capital costs from
the future gross revenue. Operating expenditures include field operating costs,
ad valorem taxes, and the estimated expenses of direct supervision but do not
include that portion of general administrative costs sometimes allocated to
production. Future income tax expenses were not taken into account in the
preparation of these estimates. Present worth is defined as future net revenue
discounted at a specified arbitrary discount rate compounded

monthly over the expected period of realization. This report shows present worth
values using a discount rate of 10 percent.

     Estimates of oil, condensate, and gas reserves and future net revenue
should be regarded only as estimates that may change as further production
history and additional information become available. Not only are such reserves
and revenue estimates based on that information which is currently available,
but such estimates are also subject to the uncertainties inherent in the
application of judgmental factors in interpreting such information.

AUTHORITY

     This report was prepared at the request of Mr. Douglas H. Woodul, Vice
President -- Production, Domain.

SOURCE OF INFORMATION

     Information used in the preparation of this report was obtained from the

                           CLASSIFICATION OF RESERVES

     Petroleum reserves included in this report are classified as proved and are
judged to be economically producible in future years from known reservoirs under
existing economic and operating conditions and assuming continuation of current
regulatory practices using conventional production methods and equipment. In the
analyses of production-decline curves, reserves were estimated only to the limit
of economic rates of production under existing economic and operating conditions
using prices and costs as of the date the estimate is made, including
consideration of changes in existing prices provided only by contractual
arrangements but not including escalations based upon future conditions. The
petroleum reserves are classified as follows:

          PROVED -- Reserves that have been proved to a high degree of certainty
     by analysis of the producing history of a reservoir and/or by volumetric
     analysis of adequate geological and engineering data. Commercial
     productivity has been established by actual production, successful testing,
     or in certain cases by favorable core analyses and electrical-log
     interpretation when the producing characteristics of the formation are
     known from nearby fields. Volumetrically, the structure, areal extent,
     volume, and characteristics of the reservoir are well defined by a
     reasonable interpretation of adequate subsurface well control and by known
     continuity of hydrocarbon-saturated material above known fluid contacts, if
     any, or above the lowest known structural occurrence of hydrocarbons.

          DEVELOPED -- Reserves that are recoverable from existing wells with
     current operating methods and expenses.

          Developed reserves include both producing and nonproducing reserves.
     Estimates of producing reserves assume recovery by existing wells producing
     from present completion intervals with normal operating methods and
     expenses. Developed nonproducing reserves are in reservoirs behind the
     casing or at minor depths below the producing zone and are considered
     proved by production from other wells in the field, by successful
     drill-stem tests, or by core analyses from the particular zones.
     Nonproducing reserves require only moderate expense to be brought into
     production.

          UNDEVELOPED -- Reserves that are recoverable from additional wells yet
     to be drilled.

          Undeveloped reserves are those considered proved for production by
     reasonable geological interpretation of adequate subsurface control in
     reservoirs that are producing or proved by other wells but are not
     recoverable from existing wells. This classification of reserves requires
     drilling of additional wells, major deepening of existing wells, or
     installation of enhanced recovery or other facilities.

     Reserves recovered by enhanced recovery methods, such as injection of
external fluids to provide energy not inherent in the reservoirs, may be
classified as proved developed or proved undeveloped reserves depending upon the
extent to which such enhanced recovery methods are in operation. These reserves
are considered to be proved only in cases where a successful fluid injection
program is in operation, a pilot program indicates successful fluid injection,
or information is available concerning the successful application of such
methods in the same reservoir and it is reasonably certain that the program will
be implemented.

                             ESTIMATION OF RESERVES

     Estimates of reserves were prepared by the use of standard geological and
engineering methods generally accepted by the petroleum industry. The method or
combination of methods used in the analysis of each reservoir was tempered by
experience with similar reservoirs, stage of development, quality and
completeness of basic data, and production history.

     When applicable, the volumetric method was used to estimate the original
oil in place (OOIP) and original gas in place (OGIP). Structure maps were
prepared to delineate each reservoir, and isopach maps were constructed to
estimate reservoir volumes. Electrical logs, radioactivity logs, core analyses,
and other available data were used to prepare these maps as well as to calculate
representative values for porosity and water saturation. When adequate data were
available and when circumstances justified, material balance and other
engineering methods were used to estimate OOIP or OGIP.

     Estimates of ultimate recovery were obtained after applying recovery
factors to OOIP or OGIP. These recovery factors were based on consideration of
the type of energy inherent in the reservoirs, analyses of the petroleum, the
structural positions of the properties, and the production histories. When
applicable, material balance and other engineering methods were used to estimate
recovery factors. An analysis of reservoir performance, including production
rate, reservoir pressure, and gas-oil ratio behavior, was used in the
calculation of reserves.

     For depletion-type reservoirs or those whose performance disclosed a
reliable decline in producing-rate trends or other diagnostic characteristics,
reserves were estimated by the application of appropriate decline curves or
other performance relationships. In the analyses of production-decline curves,
reserves were estimated only to the limits of economic production based on
current economic conditions.

     In certain cases, when the previously named methods could not be used,
reserves were estimated by analogy with similar wells or reservoirs for which
more complete data were available.

     Future oil and gas producing rates estimated for this report are based on
production rates considering the most recent data available or, in certain
cases, are based on estimates provided by Domain. The rates used for future
production are estimated to be within the capacity of a well or reservoir to
produce.

     Data available from wells drilled on the appraised properties through
December 31, 1996, were used in estimating gross ultimate recovery. Gross
production estimated to December 31, 1996, when applicable, was deducted from
gross ultimate recovery to arrive at estimates of gross reserves. This required
that production rates be estimated for up to 5 months since production data were
available only through July 1996 in certain fields.

      Gas reserves are expressed as salable reserves at a temperature of 60
degrees Fahrenheit (degree F) and at the legal pressure bases of the states or
areas in which the reserves are located. Condensate reserves estimated herein
are those to be obtained by normal separator recovery.

using guidelines established by the Securities and Exchange Commission (SEC) and
the Financial Accounting Standards Board (FASB). The initial and future prices
and producing rates used in this report have been reviewed by Domain and it has
represented that the gas prices and rates used herein are those that Domain
could reasonably expect to receive.

     In this report, values for proved reserves are based on projections of
estimated future production and revenue prepared for these properties. The
assumptions used for estimating future prices and costs are as follows:

DOMAIN

        The oil reserves shown include crude oil and condensate. Oil volumes are
expressed in barrels which are equivalent to 42 United States gallons. Gas
volumes are expressed in thousands of standard cubic feet (MCF) at the contract
temperature and pressure bases.

                                      A-12

        The estimated reserves and future revenue shown are for proved developed
producing, proved developed non-producing, and proved undeveloped reserves. In
accordance with SEC guidelines, our estimates do not include any value for
probable or possible reserves which may exist for these properties. Our
estimates do not include any value which could be attributed to interests in
undeveloped acreage beyond those tracts for which undeveloped reserves have been
estimated.

        Future gross revenue is Domain and DEPC Fund's share of the gross
(8/8ths) revenue from the properties. Future net revenue is after deducting
future capital costs, operating expenses, any applicable payments to net profits
interests, and abandonment costs, but before consideration of federal income
taxes. In accordance with SEC guidelines, the future net revenue has been
discounted at an annual rate of 10 percent to determine its "present worth." The
present worth is shown to indicate the effect of time on the value of money and
should not be construed as being the fair market value of the properties.

        For the purposes of this report, a field inspection of the properties
has not been performed nor has the mechanical operation or condition of the
wells and their related facilities been examined. We have not investigated
possible environmental liability related to the properties; therefore, our
estimates do not include any costs which may be incurred due to such possible
liability. Also, our estimates do not include any salvage value for the lease
and well equipment, but do include our estimates of the costs to abandon the
wells, platforms, and production facilities. Abandonment costs are included with
other capital investments.

        The oil and gas prices used in this report are the actual prices
received on December 31, 1996. Oil and gas prices are held constant in
accordance with SEC guidelines.

        Lease and well operating costs are based on operating expense records of
Domain Energy Corporation. These costs include the per-well overhead expenses
allowed under joint operating agreements along with costs estimated to be
incurred at and below the district and field levels. Headquarters general and
administrative overhead expenses of Domain Energy Corporation are not included.
Lease and well operating costs are held constant in accordance with SEC
guidelines. Capital costs are included as required for workovers, new
development wells, and production equipment.

        We have made no investigation of potential gas volume and value
imbalances which may have resulted from overdelivery or underdelivery to the
Domain or the DEPC Fund interests. Therefore, our estimates of reserves and
future revenue do not include adjustments for the settlement of any such
imbalances; our projections are based on Domain and the DEPC Fund receiving
their net revenue interest share of estimated future gross gas production.

        The reserves included in this report are estimates only and should not
be construed as exact quantities. They may or may not be recovered; if
recovered, the revenues therefrom and the costs related thereto could be more or
less than the estimated amounts. A substantial portion of these reserves are for
behind pipe zones and undeveloped locations. Therefore, these reserves are based
on estimates of reservoir volumes and recovery efficiencies along with analogies
to similar production. As such reserve estimates are usually subject to greater
revision than those based on substantial production and pressure data, it may be
necessary to revise these estimates up or down in the future as additional
performance data become available. The sales rates, prices received for the
reserves, and costs incurred in recovering such reserves may vary from
assumptions included in this report due to governmental policies and
uncertainties of supply and demand. Also, estimates of reserves may increase or
decrease as a result of future operations.

        In evaluating the information at our disposal concerning this report, we
have excluded from our consideration all matters as to which legal or
accounting, rather than engineering and geological, interpretation may be
controlling. As in all aspects of oil and gas evaluation, there are
uncertainties inherent in the interpretation of engineering and geological data;
therefore, our conclusions necessarily represent only informed professional
judgments.

        The titles to the properties have not been examined by Netherland,
Sewell & Associates, Inc., nor has the actual degree or type of interest owned
been independently confirmed. The data used in our estimates were obtained from
Domain Energy Ventures Corporation, Domain Energy Corporation, other interest
owners, various operators of the properties, and the nonconfidential files of
Netherland, Sewell & Associates, Inc. and were accepted as accurate. We are
independent petroleum engineers, geologists, and geophysicists; we do not own an
interest in these properties and are not employed on a contingent basis. Basic
geologic and field performance data together with our engineering work sheets
are maintained on file in our office.

                                               Very truly yours,

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 102 of the DGCL allows a corporation to eliminate the personal
liability of directors of a corporation to the corporation or to any of its
stockholders for monetary damage for a breach of his fiduciary duty as a
director, except in the case where the director breached his duty of loyalty,
failed to act in good faith, engaged in intentional misconduct or knowingly
violated a law, authorized the payment of a dividend or approved a stock
repurchase in violation of Delaware corporate law or obtained an improper
personal benefit. The Company's Certificate of Incorporation, a copy of which is
filed as Exhibit 3.1, contains a provision which, in substance, eliminates
directors' personal liability as set forth above.

     Section 145 of the DGCL provides that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was a director, officer, employee or agent of the corporation or is or was
serving at its request in such capacity in another corporation or business
association against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Company's Certificate
of Incorporation, a copy of which is filed as Exhibit 3.1, contains a provision
which, in substance, provides for indemnification as set forth above.

     The Company has purchased directors' and officers' liability insurance,
which will indemnify the directors and officers of the Company against damages
arising out of certain kinds of claims that might be made against them based on
their negligent acts or omissions while acting in their capacity as such.

     The form of Underwriting Agreement filed as Exhibit 1.1 to this
Registration Statement contains certain provisions for indemnification of
directors and officers of the Company and the Underwriters against civil
liabilities under the Securities Act.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     On December 31, 1996, the Company sold 7,177,682 shares of Common Stock at
$4.1796 per share to Fund VII and, through a wholly-owned subsidiary of the
Company, issued an $8.0 million promissory note in favor of Fund VII, which, at

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes to provide to the
Underwriters, at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person of the registrant in connection
with the securities being registered, the registrant will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.

     The undersigned registrant hereby undertakes that:

          (1)  For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or

                                   OF

                        DOMAIN ENERGY CORPORATION


            DOMAIN ENERGY CORPORATION, a corporation duly incorporated by the
filing of its original Certificate of Incorporation with the Secretary of State
of the State of Delaware on December 30, 1996 (the "Company"), desiring to amend
said Certificate of Incorporation, such amended and restated Certificate of
Incorporation having been duly adopted in accordance with Section 245 of the

which the Company shall have authority to issue is 30,000,000 shares, consisting

purpose(s) as the Board of Directors may from time to time determine.

               Shares of Preferred Stock may be issued from time to time in one
or more series of any number of shares as may be determined from time to time by
the Board of Directors; provided that the aggregate number of shares issued and

accounts of the Company.

respect of any matter occurring, or any cause of action, suit or claim that, but
for this paragraph (a) of this Article, would accrue or arise, prior to such
amendment, repeal or adoption of an inconsistent provision.

                           (b)  The Corporation shall indemnify
any person who was or is a party or is threatened to be made a party to, or
testifies in, any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative in nature, by reason of

the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, employee benefit plan, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action,

                                ARTICLE I

                              STOCKHOLDERS

            SECTION 1. ANNUAL MEETINGS. The annual meeting of stockholders for

stockholder. Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

            The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by this
section or the books of the Corporation, or to vote in person or by proxy at any
meeting of stockholders.

            SECTION 5. QUORUM. Except as otherwise provided by law or the
Corporation's Certificate of Incorporation, a quorum for the transaction of
business at any meeting of stockholders shall consist of the holders of record
of a majority of the issued and outstanding shares of the capital stock of the
Corporation entitled to vote at the meeting, present in person or by proxy. At
all meetings of the stockholders at which a quorum is present, all matters,
except as otherwise provided by law or the Certificate of Incorporation, shall
be decided by the vote of the holders of a majority of the shares entitled to
vote thereat present in person or by proxy. If there be no such quorum, the
holders of a majority of such shares so present or represented may adjourn the
meeting from time to time, without further notice, until a quorum shall have
been obtained. When a quorum is once present it is not broken by the subsequent
withdrawal of any stockholder.

            SECTION 6. ORGANIZATION. Meetings of stockholders shall be presided
over by the Chairman, if any, or if none or in the Chairman's absence the
Vice-Chairman, if any, or if none or in the Vice-Chairman's absence the
President, if any, or if none or in the President's absence a VicePresident, or,
if none of the foregoing is present, by a chairman to be chosen by the
stockholders entitled to vote who are present in person or by proxy at the
meeting. The Secretary of the Corporation, or in the Secretary's absence an
Assistant Secretary, shall act as secretary of every meeting, but if neither the
Secretary nor an Assistant Secretary is present, the presiding officer of the
meeting

                                        2
<PAGE>
shall appoint any person present to act as secretary of the meeting.

            SECTION 7. VOTING; PROXIES; REQUIRED VOTE. (a) At each meeting of
stockholders, every stockholder shall be entitled to vote in person or by proxy
appointed by instrument in writing, subscribed by such stockholder or by such
stockholder's duly authorized attorney-in-fact (but no such proxy shall be voted
or acted upon after three years from its date, unless the proxy provides for a
longer period), and, unless the Certificate of Incorporation provides otherwise,
shall have one vote for each share of stock entitled to vote registered in the
name of such stockholder on the books of the Corporation on the applicable
record date fixed pursuant to these By-laws. At all elections of directors the
voting may but need not be by ballot and a plurality of the votes cast there
shall elect. Except as otherwise required by law or the Certificate of
Incorporation, any other action shall be authorized by a majority of the votes
cast.

            (b) Any action required or permitted to be taken at any meeting of
stockholders may, except as otherwise required by law or the Certificate of
Incorporation, be taken without a meeting, without prior notice and without a
vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of record of the issued and outstanding capital stock of
the Corporation having a majority of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted, and the writing or writings are filed with the permanent
records of the Corporation. Prompt notice of the taking of corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing.

            SECTION 8. INSPECTORS. The Board of Directors, in advance of any
meeting, may, but need not, appoint one or more inspectors of election to act at
the meeting or any adjournment thereof. If an inspector or inspectors are not so
appointed, the person presiding at the meeting may, but need not, appoint one or
more inspectors. In case any person who may be appointed as an inspector fails
to appear or act, the vacancy may be filled by appointment made by the directors
in advance of the meeting or at the meeting by the person presiding thereat.
Each inspector, if any, before entering upon the discharge of his or her duties,
shall take

<PAGE>
and sign an oath faithfully to execute the duties of inspector at such meeting
with strict impartiality and according to the best of his ability. The
inspectors, if any, shall determine the number of shares of stock outstanding
and the voting power of each, the shares of stock represented at the meeting,
the existence of a quorum, and the validity and effect of proxies, and shall
receive votes, ballots or consents, hear and determine all challenges and
questions arising in connection with the right to vote, count and tabulate all
votes, ballots or consents, determine the result, and do such acts as are proper
to conduct the election or vote with fairness to all stockholders. On request of
the person presiding at the meeting, the inspector or inspectors, if any, shall
make a report in writing of any challenge, question or matter determined by such
inspector or inspectors and execute a certificate of any fact found by such
inspector or inspectors.


                               ARTICLE II

Delaware. The number of directors constituting the entire Board shall be six
(6), or such larger number as may be fixed from time to time by action of the
stockholders or Board of Directors, one of whom may be selected by the Board of
Directors to be its Chairman. The use of the phrase "entire Board" herein refers

no vacancies.

            (b) Directors who are elected at an annual meeting of stockholders,
and directors who are elected in the interim to fill vacancies and newly created
directorships, shall hold office until the next annual meeting of stockholders

<PAGE>
            (c) Directors may be paid their expenses, if any, of attendance at
each meeting of the Board of Directors and may be paid a fixed sum for
attendance at each meeting of the Board of Directors or a stated salary as
director. No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

            SECTION 3. QUORUM AND MANNER OF VOTING. Except as otherwise provided
by law, a majority of the entire Board shall constitute a quorum. A majority of
the directors present, whether or not a quorum is present, may adjourn a meeting
from time to time to another time and place without notice. The vote of the
majority of the directors present at a meeting at which a quorum is present

            SECTION 4. CHAIRMAN OF THE BOARD. The Chairman of the Board of
Directors, if there be one, shall be elected by a majority of the directors
present and shall preside at all meetings of the Board of Directors and shall

may be held at any place within or without the State of Delaware, as may from
time to time be fixed by resolution of the Board of Directors, or as may be
specified in the notice of meeting.

stockholders, the newly elected Board of Directors shall meet for the purpose of
the election of officers and the transaction of such other business as may
properly come before the meeting. Such meeting may be held without notice

            SECTION 1. LOCATION. The books and records of the Corporation may be
kept at such place or places within or outside the State of Delaware as the
Board of Directors or the respective officers in charge thereof may from time to
time determine. The record books containing the names and addresses of all

(a) In order that the Corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted by
the Board of Directors and which record date shall not be more than 60 nor less
than 10 days before the date of such meeting. If no record date is fixed by the
Board of Directors, the

                                  9
<PAGE>
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held. A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

            (b) In order that the Corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors and which date shall not be more than 10 days after the date upon
which the resolution fixing the record date is adopted by the Board of
Directors. If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the Board of Directors is
required, shall be the first date on which a signed written consent setting
forth the action taken or proposed to be taken is delivered to the Corporation
by delivery to its registered office in this State, its principal place of
business, or an officer or agent of the Corporation having custody of the book
in which proceedings of meetings of stockholders are recorded. Delivery made to
the Corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been fixed by
the Board of Directors and prior action by the Board of Directors is required by
law, the record date for determining stockholders entitled to consent to
corporate action in writing without a meeting shall be at the close of business
on the day on which the Board of Directors adopts the resolution taking such
prior action.

            (c) In order that the Corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix a record date, which record date
shall not precede the date upon which the resolution fixing the record date is
adopted and which record date shall be not more than 60 days

                                  10
<PAGE>
prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business

                               ARTICLE VI

                     CERTIFICATES REPRESENTING STOCK

            SECTION 1. CERTIFICATES; SIGNATURES. The shares of the Corporation
shall be represented by certificates, provided that the Board of Directors of
the Corporation may provide by resolution or resolutions that some or all of any
or all classes or series of its stock shall be uncertifi- cated shares. Any such
resolution shall not apply to shares represented by a certificate until such
certificate is surrendered to the Corporation. Notwithstanding the adoption of
such a resolution by the Board of Directors, every holder of stock represented
by certificates and upon request every holder of uncertificated shares shall be
entitled to have a certificate, signed by or in the name of the Corporation by
the Chairman or Vice-Chairman of the Board of Directors, or the President or
Vice-President, and by the Treasurer or an Assistant Treasurer, or the Secretary
or an Assistant Secretary of the Corporation, representing the number of shares
registered in certificate form. Any and all signatures on any such certificate
may be facsimiles. In case any officer, transfer agent or registrar who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the Corporation with the same effect
as if he were such officer, transfer agent or registrar at the date of issue.
The name of the holder of record of the shares represented thereby, with the
number of such shares and the date of issue, shall be entered on the books of
the Corporation.

            SECTION 2. TRANSFERS OF STOCK. Upon compliance with provisions
restricting the transfer or registration of transfer of shares of stock, if any,
shares of capital stock shall be transferable on the books of the Corporation
only by the holder of record thereof in person, or by duly authorized attorney,
upon surrender and cancellation of certificates for a like number of shares,
properly endorsed, and the payment of all taxes due thereon.

                                  11
<PAGE>
            SECTION 3. FRACTIONAL SHARES. The Corporation may, but shall not be
required to, issue certificates for fractions of a share where necessary to
effect authorized transactions, or the Corporation may pay in cash the fair
value of fractions of a share as of the time when those entitled to receive such
fractions are determined, or it may issue scrip in registered or bearer form
over the manual or facsimile signature of an officer of the Corporation or of
its agent, exchangeable as therein provided for full shares, but such scrip
shall not entitle the holder to any rights of a stockholder except as therein
provided.

            The Board of Directors shall have power and authority to make all
such rules and regulations as it may deem expedient concerning the issue,
transfer and registration of certificates representing shares of the
Corporation.

            SECTION 4. LOST, STOLEN OR DESTROYED CERTIFICATES. The Corporation
may issue a new certificate of stock in place of any certificate, theretofore
issued by it, alleged to have been lost, stolen or destroyed, and the Board of
Directors may require the owner of any lost, stolen or destroyed certificate, or
his legal representative, to give the Corporation a bond sufficient to indemnify
the Corporation against any claim that may be made against it on account of the
alleged loss, theft or destruction of any such certificate or the issuance of
any such new certificate.

            Subject always to the provisions of law and the Certificate of
Incorporation, the Board of Directors shall have full power to determine whether
any, and, if any, what part of any, funds legally available for the payment of
dividends shall be declared as dividends and paid to stockholders; the division
of the whole or any part of such funds of the Corporation shall rest wholly
within the lawful discretion of the Board of Directors, and it shall not be
required at any time, against such discretion, to divide or pay any part of such
funds among or to the stockholders as dividends or otherwise; and before payment
of any dividend, there may be set aside out of any funds of the Corporation
available for dividends such sum or sums as the Board of Directors from time to
time, in its absolute discretion,

                                  12
<PAGE>
thinks proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the Corporation, or
for such other purpose as the Board of Directors shall think conducive to the
interest of the Corporation, and the Board of Directors may modify or abolish
any such reserve in the manner in which it was created.

                              RATIFICATION

            Any transaction, including any transaction questioned in any lawsuit
on the ground of lack of authority, defective or irregular execution, adverse
interest of director, officer or stockholder, non-disclosure, miscomputation, or
the application of improper principles or practices of accounting, may be
ratified before or after judgment, by the Board of Directors or by the
stockholders, and if so ratified shall have the same force and effect as if the
questioned transaction had been originally duly authorized. Such ratification
shall be binding upon the Corporation and its stockholders and shall constitute
a bar to any claim or execution of any judgment in respect of such transaction.

such form and contain such other words and/or figures as the Board of Directors
shall determine. The corporate seal may be used by printing, engraving,
lithographing, stamping or otherwise making, placing or affixing, or causing to
be printed, engraved, lithographed, stamped or otherwise made, placed or
affixed, upon any paper or document, by any process whatsoever, an impression,
facsimile or other reproduction of said corporate seal.

                        ARTICLE III. CORPORATE GOVERNANCE

            SECTION 3.1.  BOARD OF DIRECTORS.

            (a) The Securityholders and the Company hereby agree that at all
times after the Closing Date, the Board of Directors of the Company and the
board of directors (or comparable governance body of any partnership or similar
entity) of each significant subsidiary (each, a "Subsidiary Board"), shall
consist entirely of the members described in this Section 3.1(a), except that
(i) the First Reserve Stockholders may in their discretion elect (which election
may be revoked at any time by the First Reserve Stockholders) to designate fewer
than three persons, or no persons at all, to be members of any Subsidiary Board
and (ii) the Management Investors may in their discretion elect (which election
may be revoked at any time by the Management Investors) to designate fewer than
two persons, or no persons at all, to be members of any Subsidiary Board,
PROVIDED, HOWEVER, that if the Management Investors designate only one person to
any such board of directors, such person must be the Chief Executive Officer of
the Company. On the Closing Date, and from time to time thereafter, the
Securityholders shall take all such actions as may be necessary or appropriate
to cause the persons described below to be elected or re-elected as the members
of the Board of Directors and each Subsidiary Board and to be maintained in such
positions at all times:

                  (i) three persons designated by the First Reserve
            Stockholders; and

                                       16
<PAGE>
                  (ii) two persons designated by the Management Investors, one
            of whom must be the Chief Executive Officer of the Company;

            PROVIDED, HOWEVER, that (i) if Michael V. Ronca is not the Chief
Executive Officer of the Company, the First Reserve Stockholders shall have the
right to designate all of the members of the Board of Directors and the right of
the Management Investors to designate members of the Subsidiary Boards shall
terminate, (ii) if the First Reserve Stockholders own less than 50% of the
outstanding Common Stock, calculated on a fully diluted basis, the First Reserve
Stockholders shall have the right to designate two members of the Board of
Directors and (iii) if the First Reserve Stockholders own less than 10% of the
outstanding Common Stock, calculated on a fully diluted basis, the First Reserve
Stockholders shall have the right to designate one member of the Board of
Directors. For the purposes of this Article III, all actions to be taken by the
First Reserve Stockholders shall be taken only by the holders of a majority of
the Stock owned by the First Reserve Stockholders at the time such action is
taken. For the purposes of this Article III, all actions to be taken by the
Management Investors will be taken only by the holders of a majority of the
Stock owned by the Management Investors at the time such action is taken.

            (b) Each Securityholder hereby agrees to vote all shares of Stock
owned or held of record by such Securityholder, at each annual or special
meeting of stockholders of the Company at which directors of the Company are to
be elected, in favor of, or to take all actions by written consent in lieu of
any such meeting as are necessary to cause, the election or re-election as
members of the Board of Directors of those individuals described in Section

            (c) Each committee of the Board of Directors and each Subsidiary
Board shall include a number of directors designated by the First Reserve
Stockholders and the Management Investors (rounded up to the nearest whole
number) equivalent in each case to the proportion of directors designated by
each of them who are then serving on the whole Board of Directors or such whole
Subsidiary Board, as applicable; PROVIDED, HOWEVER that the Management Investors
shall not have the right to designate any directors to serve on any audit
committee or similar committee of the Board of Directors or any Subsidiary Board
and the Compensation Committee of the Board of Directors will be constituted as
described below. The committees of the Board of Directors shall consist of an
Audit Committee and a Compensation 

                                       17
<PAGE>
Committee each of which shall, subject to Section 2.1, have functions
customarily performed by such committees. The Audit Committee shall consist of
two directors, each of whom were designated by the First Reserve Stockholders to
sit on the Board of Directors. The Compensation Committee shall consist of three
directors, two of whom were designated by the First Reserve Stockholders to sit
on the Board of Directors and one of whom is the Chief Executive Officer of the
Company.

            (d) Unless otherwise agreed by the parties hereto, the Board of
Directors and each Subsidiary Board shall follow the following procedures:

                      (i) MEETINGS. Special Meetings of the applicable board of
      directors may be held at any time upon the call of at least two directors,
      including (in the event the First Reserve Stockholders have a designee on
      such board of directors) one designee of the First Reserve Stockholders,
      by oral, telephonic, telegraphic or facsimile notice duly given or sent at
      least one day, or by written notice sent by express mail at least three
      days, before the meeting to each director. Reasonable efforts shall be
      made to ensure that each director actually receives timely notice of any
      meeting. The annual meeting of the Board of Directors and each Subsidiary
      Board shall be held without notice immediately following the annual
      meeting of stockholders of the Company or such subsidiary, as the case may
      be.

                     (ii) AGENDA. A reasonably detailed agenda shall be supplied
      to each director reasonably in advance of each meeting of the applicable
      board of directors, together with other appropriate documentation with
      respect to agenda items calling for board action, to inform adequately
      directors regarding matters to come before the board. Any director wishing
      to place a matter on the agenda for any meeting of the applicable board of
      directors may do so by communicating with the chairman of such board of
      directors sufficiently in advance of the meeting of the applicable board
      of directors so as to permit timely dissemination to all directors of
      information with respect to the agenda items.

            (e) Each of the First Reserve Stockholders that is not directly
represented on the Board of Directors or any Subsidiary Board shall be entitled
to designate a nonvoting observer to attend meetings of any such Board of
Directors or Subsidiary Board (which designation shall be provided in writing to
the Company or a Subsidiary, as the case may be, a reasonable time in advance of
such meetings). The Company or the subsidiary, as the 

                                       18
<PAGE>
case may be, shall provide each such observer with the same notice of, and
information regarding, meetings of the Board of Directors or Subsidiary Board as
that provided to directors. Each such observer shall be provided reasonable
access to the books, records and properties of the Company or the subsidiary and
shall be provided with a reasonable opportunity to discuss the business and
affairs of the Company or subsidiary with the officers of the Company or
subsidiary, provided that the First Reserve Stockholders shall cause all
information relating to the Company or the subsidiary that is provided to such
observer to be held in strict confidence.

            (f) The Company shall pay the reasonable out-of-pocket expenses
incurred by each director in connection with attending (i) the meetings of the
Board of Directors, any Subsidiary Board and any committee thereof and (ii) any
other meetings at the request of the Company or any of its subsidiaries. So long
as any director designated pursuant to Section 3.1(a) serves on the Board of
Directors or a Subsidiary Board and for six years thereafter, the Company shall
maintain directors and officers indemnity insurance coverage satisfactory to the
holders of a majority of the then outstanding Common Stock and the
organizational documents of each of the Company and each of its subsidiaries, as
appropriate, shall provide for indemnification and exculpation of directors to
the fullest extent permitted under applicable law.

            SECTION 3.2. REMOVAL. If a director designated and elected pursuant
to Section 3.1,

                      (i) has been designated pursuant to Section 3.1(a)(i),
      and, during such director's term as director, the First Reserve
      Stockholders request by written notice to the other Securityholders that
      such director be removed;

                     (ii) has been designated pursuant to Section 3.1(a)(ii),
      and, during such director's term as director, the Management Investors
      request by written notice to the other Securityholders that such directors
      be removed; or

                    (iii) has been designated pursuant to Section 3.1(a)(ii) and
      Michael V. Ronca is not the Chief Executive Officer of the Company, and
      the First Reserve Stockholders request by written notice to the other
      Securityholders that such director be removed;

then such director shall be removed upon the affirmative vote of the holders of
a majority of the outstanding shares of Stock, and 

                                       19
<PAGE>
each Securityholder hereby agrees promptly to vote all shares of Stock owned or
held of record by it and to take all such other actions as may be necessary or
appropriate to effect such removal in accordance with such request.

            SECTION 3.3. VACANCIES. In the event that a vacancy is created on
the Board of Directors at any time by the death, disability, retirement,
resignation or removal of any director or for any other reason there shall exist
or occur any vacancy on the Board of Directors, each Securityholder hereby
agrees to take such actions as will result in the election or appointment of a
new director or directors in accordance with Section 3.1.


                      ARTICLE IV. TRANSFERS OF SECURITIES.

            SECTION 4.1. RESTRICTIONS ON TRANSFER. (a) Each Securityholder
agrees that it will not, directly or indirectly, offer, sell, transfer, assign
or otherwise dispose of (or make any exchange, gift, assignment or pledge of)

of its shares of Stock or Stock Rights, except (i) as provided in Section 4.2,

4.1 (a) shall not apply to any of the following transfers: 

            (a) From any First Reserve Stockholder to any affiliate of the First
Reserve Stockholders, provided that such affiliate shall assume in writing the
obligations hereunder of a First Reserve Stockholder, which writing shall in
form and substance be reasonably satisfactory to the Company and the Management
Investors' board designees.

            (b) From any Management Investor to a trust solely for such Person's
benefit or the benefit of such Person's spouse or children (a "Purchaser's
Trust"), PROVIDED that such Person acts as trustee and retains the sole power to
direct voting and disposition of such shares; and, PROVIDED, FURTHER, that any
such 

                                       20

            (e)   To the public pursuant to a Public Offering.

Agreement as follows:

            (b) The obligations of each party hereto shall be binding upon each
transferee to whom shares of Stock or Stock Rights are transferred by any party

                           ARTICLE V. PURCHASE RIGHTS.

            SECTION 5.1.  TRANSFERS BY A MANAGEMENT INVESTOR.

            Except for transfers permitted by Section 4.2(b) or a sale of shares
of Stock pursuant to an effective registration statement under the Securities
Act filed by the Company or pursuant to Sections 5.2, 5.4 or 5.5 of this
Agreement, each Management Investor agrees that he will not transfer any shares
of the Stock of the Company at any time prior to the fifth anniversary of the
date hereof. No transfer of any such shares in violation hereof shall be made or
recorded on the books of the Company and any such transfer shall be void and of
no effect.

            If at any time after the fifth anniversary of the date hereof and
prior to a Public Offering, a Management Investor receives a bona fide offer to
purchase any or all of his shares of Stock (the "Offer") from a third party (the
"Offeror") which such Management Investor wishes to accept, such Management
Investor shall cause the Offer to be reduced to writing and shall 

                                       22
<PAGE>
notify the Company in writing of his wish to accept the Offer. A Management
Investor's notice shall contain an irrevocable offer to sell such shares of
Stock to the Company (in the manner set forth below) at a purchase price equal
to the price contained in, and on the same terms and conditions of, the Offer,
and shall be accompanied by a true copy of the Offer (which shall identify the
Offeror). At any time within 30 days after the date of the receipt by the
Company of a Management Investor's notice, the Company shall have the right and
option to purchase, or to arrange for a third party to purchase, all of the
shares of Stock covered by the Offer either (i) at the same price and on the
same terms and conditions as the Offer or (ii) if the Offer includes any
consideration other than cash, then at the sole option of the Company, at the
equivalent all cash price, determined in good faith by the Company's Board of
Directors, by delivering a certified bank check or checks in the appropriate
amount (and any such non-cash consideration to be paid) to the applicable
Management Investor at the principal office of the Company against delivery of
certificates or other instruments representing the shares of the Stock so
purchased, appropriately endorsed by the applicable Management Investor. If at
the end of such 30 day period, the Company has not tendered the purchase price
for such shares in the manner set forth above, the applicable Management
Investor may during the succeeding 60 day period sell not less than all of the
shares of Stock covered by the Offer to the Offeror at a price and on terms no
less favorable to such Management Investor than those contained in the Offer.
Promptly after such sale, the applicable Management Investor shall notify the
Company of the consummation thereof and shall furnish such evidence of the
completion and time of completion of such sale and of the terms thereof as may
reasonably be requested by the Company. If, at the end of 60 days following the
expiration of the 30 day period for the Company to purchase the Stock, the
applicable Management Investor has not completed the sale of such shares of the
Stock as aforesaid, all the restrictions on sale, transfer or assignment
contained in this Agreement shall again be in effect with respect to such shares
of the Stock.

            SECTION 5.2.  PUTS AND CALLS.

            The Company and each Management Investor (which term, for purpose of
this Section 5.2, shall include all Permitted Transferees thereof as the context
may require) shall be subject to the following purchase and sale obligations and
rights:

            (a) Subject to Section 5.2(c), upon any termination of employment of
a Management Investor by reason of:

         (ii)     retirement from the Company and its subsidiaries at age 62 or
                  over (or such other age as may be approved by the Board of
                  Directors of the Company) after having been employed by the
                  Company or any subsidiary for at least three years after the
                  Closing Date ("Normal Retirement"), or

        (iii)     involuntary termination from the Company and its subsidiaries
                  without Cause or voluntary termination from the Company and
                  its subsidiaries for Good Reason,

the Management Investor and his Permitted Transferees or his or their
representative shall be entitled for a period of 120 days following the
effective date of such termination of employment to exercise a put (any such
put, a "Put") to the Company of all of the Stock and Vested Stock Rights of such
Management Investor or Permitted Transferees by requiring the Company to (A)
purchase such Stock at a price per share (the "Put Price") equal to (i) if such
purchase is consummated prior to the second anniversary of the Closing Date, the
Book Value or (ii) if such purchase is consummated on or after the second
anniversary of the Closing Date, the Fair Market Value and (B) purchase such
Vested Stock Rights at a price (the "Option Put Price") equal to the excess of
(x) the product of the Put Price multiplied by the number of shares to be
received upon exercise of the Vested Stock Rights over (y) the aggregate
exercise price of those shares. A Put shall be exercised by delivery of written
notice to the Company. The purchase shall be consummated within 30 days after
receipt of such notice by the Company.

            (b) (i) Subject to Section 5.2(c), upon the termination of
      employment of any Management Investor for any reason, including, without
      limitation, death or permanent disability, and provided such Management
      Investor or his Permitted Transferee shall not have previously exercised a
      Put pursuant to Section 5.2(a), the Company shall be entitled for a period
      of one year after the effective date of such termination of employment to
      exercise a call (any such call, a "Call") on all of the shares of Stock
      and all Vested Stock Rights owned by such Management Investor and his
      Permitted Transferees by requiring such Management Investor and his
      Permitted Transferees to sell to the Company all of such shares at the Put
      Price and all of such Vested Stock Rights at the Option Put Price;
      provided, however, if a Management Investor's employment is terminated by
      the Company without Cause or by the Management Investor 

                                       24
<PAGE>
      for Good Reason and the Management Investor does not desire to exercise a
      Put pursuant to Section 5.2(a), the Company shall defer its Call pursuant
      to this Section 5.2(b)(i) until the second anniversary of the date of this
      Agreement. The Company may exercise its Call by delivery of written notice
      to such Management Investor and his Permitted Transferees. Consummation of
      the sale shall occur within 30 days after delivery of such notice, at a
      purchase price per share, subject to Section 5.2(b)(ii), determined in
      accordance with the provisions of Section 5.2(a).

                     (ii) Notwithstanding Section 5.2(b)(i), any purchase of
      Stock by the Company pursuant to the exercise of any Call as a result of
      termination by the Company for Cause or termination by the Management
      Investor without Good Reason shall be made at a purchase price per share
      (the "Section 5.2(b)(ii) Call Price") equal to (1) if such purchase is
      consummated prior to the second anniversary of the Closing Date, the lower
      of (x) Book Value and (y) the price per share originally paid by such
      Management Investor (appropriately adjusted for any stock dividends,
      splits, reverse splits, combinations, recapitalizations and the like
      occurring after the Closing Date) ("Cost"), or (2) if such purchase is
      consummated on or after the second anniversary of the Closing Date, the
      lower of (x) Book Value and (y) Fair Market Value.

                    (iii) Notwithstanding Section 5.2(b)(i), any purchase of
      Vested Stock Rights by the Company pursuant to any Call as a result of
      termination by the Company for Cause or termination by the Management
      Investor without Good Reason shall be made at a price equal to the excess
      of (x) the product of the Section 5.2(b)(ii) Call Price multiplied by the
      number of shares to be received upon exercise of the Vested Stock Rights
      over (y) the aggregate exercise price of those shares.

            (c) Notwithstanding anything in Section 5.2(a) or 5.2(b) to the
contrary, if there exists and is continuing a default or an event of default on
the part of the Company or any subsidiary of the Company under any loan,
guarantee or other agreement under which the Company or any subsidiary of the
Company has borrowed money or if the repurchases referred to in Section 5.2(a)
or 5.2(b) would result in a default or an event of default on the part of the
Company or any subsidiary of the Company under any such agreement or if a
repurchase would not be permitted under the DGCL (or if the Company
reincorporates in another state, the business corporation law of such state)
(each 

                                       25
<PAGE>
such occurrence being an "Event"), the Company shall not be obligated to
repurchase any of the Stock or the Vested Stock Rights from the Management
Investor or the Permitted Transferee, as the case may be, until the first
business day which is 10 calendar days after all of the foregoing Events have
ceased to exist (the "Repurchase Eligibility Date"); provided, that the Company
shall repurchase an amount of Stock or Stock Rights (the "Permitted Number")
which is less than all of the Stock or Stock Rights held by such Management
Investor or Permitted Transferee but as to which, the purchase of a single
additional share of Stock would violate applicable law or any loan, guarantee or
other agreement described above.

            (d) The Board of Directors shall determine whether the Company will
exercise its call rights to purchase a Management Investor's (or Permitted
Transferee's) Stock pursuant to Sections
5.2(b) or 5.2(c) hereof.

            (e) If any Management Investor's marital relationship is terminated
by the death of his spouse or divorce and he does not succeed to his or her
spouse's interest in any Stock or Stock Rights, he shall have the option to
purchase all such spouse's interest and the interests of any of his or her
Permitted Transferees in any shares of Stock or Stock Rights, but only to the
extent such interests arise from such spouse's community or marital property
rights and such spouse or the executor or administrator of his or her estate and
any such Permitted Transferees (any such spouse, executor, administrator or
Permitted Transferee, the "Spouse") shall be obligated to sell such Stock or
Stock Rights to such Management Investor. The price per share at which such
Stock and Stock Rights shall be purchased shall be determined in accordance with
the provisions of Section 5.2(a). Such option must be exercised within 90 days
after such death or divorce. If such Management Investor should fail to exercise
such option within such 90 day period, the Spouse shall give prompt written
notice of such failure to the Company and each of the other Management
Investors, which notice shall describe the nature of the above referenced
interests of the Spouse in such Stock and Stock Rights. The Company shall be
entitled to exercise a call (a "Spouse Call") on all of the shares of such Stock
and on all Stock Rights owned by such Spouse, within 120 days after receiving
such notice, by requiring such Spouse to sell to the Company all of such shares.
The Company may exercise its call by delivery of written notice to such Spouse.
Consummation of the sale shall occur within 30 days after delivery of such
notice at a purchase price per share determined in accordance with the
provisions of Section 5.2(a).

                                       26
<PAGE>
            (f) If by reason of Section 5.2(c) above the Company purchases less
than all (or none) of the shares of Stock and Vested Stock Rights held by a
Seller (provided that the Company shall have purchased the Permitted Number),
then notwithstanding anything to the contrary in Section 5.2(a), 5.2(b) or
5.2(c), the Company may elect, in the case of any such Call or Spouse Call, and
shall elect, in the case of any such Put, by delivering written notice to such
Seller at the time of such purchase (or, if no such shares are purchased, within
30 days after delivery of the notice, in accordance with the provisions of
Sections 5.2(a), 5.2(b) or 5.2(c), as the case may be, of the Put or Call in
respect of such Seller), to purchase, as soon as possible after all of the
Events have ceased to exist, the remainder of such Stock and Vested Stock
Rights, up to but in no event more than the Permitted Number at the time of each
purchase and each subsequent purchase necessary to allow purchase of all the
shares and Vested Stock Rights subject to the Put or Call. In such event the
Company shall deliver to such Seller as soon as it is possible to purchase such
shares a written notice of such purchase, and such purchase shall be on the
terms and subject to the limitations contained in this Section 5.2 (including
Section 5.2(c) above), except that the purchase price to be paid shall be the
price determined with reference to the first notice given exercising the Put or
Call with respect to such Seller, plus interest thereon from the 31st day after
the date of delivery of the first notice to the closing of the applicable
purchase at the Prime Rate.

            (g) The Company shall exercise its call rights to purchase a
Management Investor's (or a Spouse's or Permitted Transferee's) Stock and Vested
Stock Rights pursuant to Sections 5.2(b), 5.2(c) or 5.2(d) hereof.
Notwithstanding the foregoing, the Company may request, but not require, the
First Reserve Stockholders to exercise the Company's rights and obligations to
purchase such Stock and Vested Stock Rights (and, if such request is made, the
First Reserve Stockholders may decide in their sole discretion whether to
exercise the Company's rights and obligations). Should the Board of Directors
fail to exercise a call on the Stock as provided in Sections 5.2(b), 5.2(c) or
5.2(d), or be unable to purchase all of the Stock and Vested Stock Rights for
cash pursuant to a Put or Call, (an "Unexercised Right"), each Management
Investor (and his Permitted Transferees) then owning Stock, other than the
Management Investor (and his Permitted Transferees) subject to the call, shall
be entitled to exercise a call (any such call, a "Management Call"), on up to a
pro rata basis (based upon the number of shares of Fully Diluted Common Stock
then beneficially owned, within 10 days after notice by the Company to the
Management Investor that it will not 

                                       27
<PAGE>
exercise its call or is unable to purchase all of the Stock for cash and Vested
Stock Rights pursuant to a Put or a Call. A Management Call shall be exercised
by delivery of written notice to the Company and to the Management Investor (or
Spouse or Permitted Transferee) whose shares and Vested Stock Rights were
subject to the Unexercised Right.

            SECTION 5.3. RIGHT OF FIRST REFUSAL FOR NEW SECURITIES.

            (a) The Company hereby grants to the Securityholders a pro rata
right of first refusal to purchase shares of any New Securities (as defined
below) which the Company may, from time to time, propose to sell and issue. Such
right of first refusal shall allow each Securityholder to purchase a pro rata
portion of the shares of Stock or Stock Rights or other securities as may be
included in the New Securities proposed to be issued. Such pro rata portions
shall be determined by reference to the aggregate number of shares of (i) Fully
Diluted Common Stock in the case of issuances to the First Reserve Stockholders
or any of their affiliates or (ii) outstanding Common Stock in the case of
issuances to Persons other than to the First Reserve Stockholders or any of
their affiliates, as the case may be, owned in each case by each Securityholder
(including the First Reserve Stockholders) before the proposed issuance of New
Securities. The right of first refusal granted hereunder shall terminate if
unexercised within thirty (30) days after receipt of the notice described in
Section 5.3(c) below.

            (b) "New Securities" shall mean any authorized but unissued shares,
and any treasury shares, of Capital Stock (including, without limitation, Common
Stock) of the Company and all rights, options or warrants to purchase Capital
Stock of the Company (including, without limitation, Stock Rights), and
securities of any type whatsoever that are, or may become, convertible into
Capital Stock of the Company; PROVIDED, HOWEVER, that the term "New Securities"
does not include (i) shares of Common Stock issued upon the exercise of Stock
Rights or other rights to acquire Stock that are (x) outstanding on the date
hereof (including, without limitation, the First Reserve Option) or (y) issued
after the date hereof in a transaction in which the Securityholders have the
right to purchase their respective pro rata portions of the relevant Stock
Rights or other rights pursuant to Section 5.3(a) hereof, in each such case in
accordance with the terms thereof or (ii) shares of Stock issued in connection
with any stock split, stock dividend or recapitalization of the Company, (iii)
securities issued by the Company pursuant to the acquisition of another
corporation or 

                                       28
<PAGE>
other entity by merger, purchase of all or substantially all of the assets or
other recapitalization, reorganization or business combination, (iv) shares of
Common Stock and Options to purchase shares of Common Stock issued to employees,
officers or directors of the Company pursuant to the Stock Purchase and Option
Plan, provided that the aggregate number of shares of Common Stock issued
pursuant to the Stock Purchase and Option Plan shall not exceed 1,000 or (v) up
to 529 shares of Common Stock issued and sold by the Company to the Management
Investors at a price per share of $3,151.4354, PROVIDED, such issuance and sale
shall have been consummated on or before February 15, 1997.

            (c) In the event the Company proposes to undertake an issuance of
New Securities, it shall give each Securityholder written notice of its
intention, describing the number of shares of Stock and/or Stock Rights or other
securities it intends to issue as New Securities, the purchase price therefor
(which shall be payable solely in cash) and the terms upon which the Company
proposes to issue the same. Each Securityholder shall have 30 days from the date
such notice is received to determine whether to purchase all or any portion of
the Securityholder's pro rata share of such New Securities for the purchase
price and upon the terms specified in the Company's notice by giving written
notice to the Company and stating therein the quantity of New Securities to be
purchased.

            (d) The obligations of the Company under this Section 5.3 shall
terminate immediately prior to any Public Offering pursuant to a firm
underwriting commitment.

            SECTION 5.4.  RIGHT TO JOIN IN SALE.

            (a) If any Securityholder or group of Securityholders proposes to
sell, dispose of or otherwise transfer in any single transaction or series of
related transactions any Securities representing more than 10% of the Fully
Diluted Common Stock (each a "Disposing Stockholder") other than (i) to the
Company, (ii) to the Company or its designee pursuant to Section 5.1 hereof or
(iii) any transfer by a First Reserve Stockholder to any affiliate of such First
Reserve Stockholder, such Disposing Stockholder shall refrain from effecting
such transaction unless, prior to the consummation thereof, each other
Securityholder shall have been afforded the opportunity to join in such sale on
a pro rata basis, as hereinafter provided.

            (b) Prior to consummation of any proposed sale, disposition or
transfer (a "Sale") of the Securities described in Section 5.4(a), the Disposing
Stockholder shall cause the Person 

                                       29
<PAGE>
or group that proposes to acquire such shares (the "Proposed Purchaser") to
offer (the "Purchase Offer") in writing to each other Securityholder (each, a
"Tag-Along Offeree") to purchase shares of Stock and/or Stock Rights owned by
such Tag-Along Offeree which are the same type, class or series proposed to be
sold by the Disposing Stockholders, such that the sum of the number of shares of
such Stock so offered to be purchased and the number of shares of Stock then
represented by the Stock Rights so offered to be purchased from such Tag-Along
Offeree shall be equal to the product obtained by multiplying the total number
of shares of the same type, class or series of Stock or other Securities being
sold by the Disposing Stockholder then owned by such Tag-Along Offeree by a
fraction, the numerator of which is the aggregate number of shares of each type,
class or series of Stock or other Securities proposed to be purchased by the
Proposed Purchaser from the Disposing Stockholder and the denominator of which
is the aggregate number of outstanding shares of each type, class or series of
Stock or other Securities that are owned by the Disposing Stockholder; PROVIDED,
however, that if after the consummation of such Sale the First Reserve
Stockholders will own less than 50% of the outstanding Common Stock, then each
Tag-Along Offeree may elect to include in such Sale all of the shares of Stock
and/or Stock Rights owned by such Tag-Along Offeree and any Purchase Offer shall
be amended to reflect any such election by the Tag-Along Offeree. Such purchase
shall be made at the price per share and on such other terms and conditions as
the Proposed Purchaser has offered to purchase each type, class or series of
Stock or other Securities, as the case may be, to be sold by the Disposing
Stockholder. Each Tag-Along Offeree shall have 20 calendar days from the date of
receipt of the Purchase Offer in which to accept such Purchase Offer, and the
closing of such purchase shall occur at the same time as the closing of the
Sale. The number of shares of Stock and/or Stock Rights, as the case may be, to
be sold to the Proposed Purchaser by the Disposing Stockholder shall be reduced
by the aggregate number of shares of Stock and/or Stock Rights, as the case may
be, purchased by the Proposed Purchaser from the Tag-Along Offerees pursuant to
the acceptance by them of Purchase Offers in accordance with the provisions of
this Section 5.4(b). In the event that a sale or other transfer subject to this
Section 5.4 is to be made to a Proposed Purchaser who is not a Securityholder,
the Disposing Stockholder shall notify the Proposed Purchaser that the sale or
other transfer is subject to this Section 5.4 and shall ensure that no sale or
other transfer is consummated without the Proposed Purchaser first complying
with this Section 5.4. It shall be the responsibility of each Disposing
Stockholder to determine whether any transaction to which it is a party is
subject to this Section 5.4.

            SECTION 5.5.  RIGHTS TO COMPEL SALE.

            (a) If the First Reserve Stockholders and their respective
affiliates propose to make a transfer of 100% of their Stock in the Company, at
any time when the First Reserve Stockholders and their affiliates own at least
50% of the Fully Diluted Common Stock, to a Person that is neither an affiliate
of the First Reserve Stockholders nor a Person with respect to which the First
Reserve Stockholders or any of their affiliates has a direct or indirect
economic interest, then the First Reserve Stockholders shall have the right,
exercisable as set forth below, to require all of the other Securityholders (the
"Remaining Securityholders") to sell all of the Stock and Vested Stock Rights
then owned by such Remaining Securityholders (the "Transfer Stock") to the
proposed transferee (the "Acquiror") for the same consideration per share of
Stock or Vested Stock Right as is being paid to the First Reserve Stockholders,
which consideration shall consist entirely of cash and/or Marketable Securities
and otherwise on the same terms as are applicable to the First Reserve
Stockholders. The purchase price for each Vested Stock Right in any such
transfer shall equal the "spread" between the exercise price for such Vested
Stock Right and the purchase price per share of Stock. The terms and conditions
other than the consideration to be received by the Remaining Securityholders for
Stock and Vested Stock Rights sold pursuant to this Section 5.5 shall be as set
forth in the applicable Purchase Agreement between the First Reserve
Stockholders and the Acquiror.

            (b) (i) the First Reserve Stockholders shall cause the terms of the
      transfer to be reduced to writing and shall provide a written notice (the
      "Compelled Sale Transfer Notice") of such transfer to the Company and the
      Company shall provide such Compelled Sale Transfer Notice to the Remaining
      Securityholders. The Compelled Sale Transfer Notice shall contain written
      notice of the exercise of the First Reserve Stockholders rights pursuant
      to Section 5.5(a) hereof, setting forth the consideration to be paid by
      the Acquiror for each type of Stock and Stock Right and the other terms
      and conditions of the transfer. Within 20 calendar days following the date
      of receipt of the Compelled Sale Transfer Notice, each of the Remaining
      Securityholders shall deliver to the First Reserve Stockholders (the
      "Notice Designee") certificates representing the Stock and instruments
      representing Stock Rights owned by such Remaining Stockholder, duly
      endorsed, together with all other documents required to be executed in
      connection with such transfer or, if such delivery is not permitted by

                                       31
<PAGE>
      applicable law, an unconditional agreement to deliver such certificates
      pursuant to this Section 5.5(b) at the closing for such transfer against
      delivery to such Remaining Securityholder of the consideration therefor.
      Such certificates shall be held by the First Reserve Stockholders in
      escrow for the benefit of the appropriate Remaining Securityholder and, if
      requested by the Remaining Securityholder, the First Reserve Stockholders
      shall execute such form of escrow agreement as is reasonably satisfactory
      to the First Reserve Stockholders and such Remaining Securityholder and
      which assures that the relevant Stock and/or Stock Rights are not
      considered property of the First Reserve Stockholders. In the event that a
      Remaining Securityholder should fail to deliver such certificates as
      aforesaid, the Company shall cause the books and records of the Company to
      show that such Stock and Stock Rights are bound by the provisions of this
      Section 5.5(b) and that such Stock and Stock Rights shall be transferred
      only to the Acquiror upon surrender for transfer by the Remaining
      Securityholder thereof.

                     (ii) If, within 150 calendar days (or such longer period
      not exceeding 210 calendar days as may be necessary to comply with any
      applicable provisions of the Hart-ScottRodino Antitrust Improvements Act
      of 1976, as amended, or to obtain other required regulatory approval)
      after the First Reserve Stockholders give the Compelled Sale Transfer
      Notice, it has not completed the sale of all the Transfer Stock, the First
      Reserve Stockholders shall return to each of the Remaining Securityholders
      all certificates representing Stock and Stock Rights that such Remaining
      Securityholders delivered for sale pursuant hereto, and all the
      restrictions on sale or other disposition contained in this Agreement with
      respect to such Stock and Stock Rights and the Stock owned by the First
      Reserve Stockholders shall again be in effect.

                    (iii) Upon the consummation of the sale of Stock held by the
      First Reserve Stockholders and the Remaining Securityholders pursuant to
      this Section 5.5, the First Reserve Stockholders shall give notice thereof
      to the Remaining Securityholders, shall (or shall cause the purchaser to)
      remit to each of the Remaining Securityholders a net amount with respect
      to the Stock and Stock Rights of such Remaining Securityholders sold
      pursuant thereto, after deduction of a pro rata portion of any related
      out-of-pocket fees and expenses payable to Persons other than the First
      Reserve Stockholders or any of its affiliates, and shall 

                                       32
<PAGE>
      furnish such other evidence of the completion and time of completion of
      such sale or other disposition and the terms thereof as may be reasonably
      requested by such Remaining Securityholders, PROVIDED that if the cash or
      the fair market value of the Marketable Securities payable to any
      Remaining Securityholder exceeds $5,000,000, such Remaining Securityholder
      shall be entitled to have such cash and/or Marketable Securities (net of
      any fees and expenses that are to be deducted in accordance with this
      Section) paid directly to the Remaining Securityholder by the Acquiror at
      the closing of the transaction.

                        ARTICLE VI. REGISTRATION RIGHTS.

            SECTION 6.1.  DEMAND REGISTRATIONS.

            (a) At any time after the first to occur of (1) a Qualified Public
Offering or (2) the first anniversary of the Closing Date, the First Reserve
Stockholders may request in writing that the Company effect the registration
under the Securities Act (other than a shelf registration made pursuant to Rule
415 of the Securities Act) of all or part of their Registrable Securities,
specifying in the request the number and types of Registrable Securities to be
registered by each such holder and the intended method of disposition thereof
(such notice is hereinafter referred to as a "Holder Request"). Upon receipt of
such Holder Request, the Company will promptly give written notice of such
requested registration to all other holders of Registrable Securities, which
other holders shall have the right, subject to the provisions of Section 6.1(h)
hereof, to include the Registrable Securities held by them in such registration
and thereupon the Company will, as expeditiously as possible, use reasonable
best efforts to effect the registration under the Securities Act of:

               (i)        the Registrable Securities which the Company has
      been so requested to register by the First Reserve
      Stockholders; and

              (ii) all other Registrable Securities which the Company has been
      requested to register by any other holder thereof by written request given
      to the Company within 30 calendar days after the giving of such written
      notice by the Company,

all to the extent necessary to permit the disposition of the Registrable
Securities so to be registered pursuant to an 

                                       33
<PAGE>
Underwritten Offering or by such other method of disposition as the First
Reserve Stockholders may specify in the Holder Request; PROVIDED, HOWEVER, that
the Company shall not be obligated to file a registration statement pursuant to
any Holder Request under this Section 6.1(a):

                  (A) Unless the Company shall have received requests for such
            registration with respect to at least 10% of the Fully Diluted
            Common Stock; or

                  (B) Other than a registration statement on Form S-3 or a
            successor short form registration statement, within a period of 6
            months after the effective date of any other registration statement
            relating to any registration request under this Section 6.1(a) that
            was not effected on Form S-3 (or any successor short form).

                  (C) Within the six month period immediately following the
            effective date of a registration previously effected by the Company
            pursuant to this Section 6.1.

            (b) Notwithstanding the foregoing provisions of Section 6.1(a), and
except as provided in Section 6.1(h), the Company shall not be obligated to file
more than an aggregate of four (4) registration statements pursuant to this
Section 6.1.

            (c) If the Company proposes to effect a registration requested
pursuant to this Section 6.1 by the filing of a registration statement on Form
S-3 (or any successor short-form registration statement), the Company will
comply with any request by the managing underwriter to effect such registration
on another permitted form if such managing underwriter advises the Company that,
in its opinion, the use of another form of registration statement is of material
importance to the success of such proposed offering.

            (d) A registration requested pursuant to Section 6.1 (a) will not be
deemed to have been effected unless the applicable registration statement has
become effective; PROVIDED, that, if after it has become effective, the offering
of Registrable Securities pursuant to such registration statement is interfered
with by any stop order, injunction or other order or requirement of the SEC or
other governmental agency or court, such registration will be deemed not to have
been effected.

                                       34
<PAGE>
            (e) The Company will pay all Registration Expenses in connection
with each of the registrations of Registrable Securities effected by it pursuant
to this Section 6.1.

            (f) Subject to any existing commitments of the Company, the First
Reserve Stockholders shall have the right to select the investment bank (or
investment banks) that shall manage the offering (collectively, the "managing
underwriter") involving a registration under this Section 6.1; provided that
such managing underwriter is reasonably acceptable to the Company.

            (g) Whenever a requested registration pursuant to this Section 6.1
involves a firm commitment underwriting (an "Underwritten Offering"), the only
shares that may be included in such Underwritten Offering are (i) Registrable
Securities, and (ii) securities of the Company which are not Registrable
Securities included in such Underwritten Offering upon the written consent of
the First Reserve Stockholders ("Company Securities").

            (h) If a registration pursuant to this Section 6.1 involves an
Underwritten Offering and the managing underwriter shall advise the Company
that, in its judgment, the number of shares proposed to be included in such
Underwritten Offering should be limited due to market conditions, then the
Company will promptly so advise each holder of Registrable Securities that has
requested registration, and the Company Securities, if any, shall first be
excluded from such Underwritten Offering to the extent necessary to meet such
limitation; and if further exclusions are necessary to meet such limitation,
Registrable Securities requested to be registered pursuant to Section 6.1(a)(i)
or Section 6.1(a)(ii) shall be excluded pro rata, based on the respective
numbers of shares of Common Stock as to which registration shall have been
requested by such Persons. If the number of Registrable Securities requested to
be registered pursuant to Section 6.1(a)(i), but that are excluded from
registration pursuant to this Section 6.1(h), is equal or greater to 10% of the
total number of Registrable Securities requested to be so registered, then such
registration by the Company shall not count as a registration for the purposes
of Section 6.1(b) only.

            (i) Notwithstanding the foregoing, this Section 6.1 shall not apply
at such time as the First Reserve Stockholders own less than 5% of the Fully
Diluted Common Stock.

            SECTION 6.2. PIGGYBACK REGISTRATIONS.

            (a) If the Company at any time proposes to register any of its
equity or debt securities under the Securities Act (other than a registration on
Form S-4 or S-8 or any successor or similar forms thereto and other than
pursuant to a registration under Section 6.1), whether or not for sale for its
own account, on a form and in a manner that would permit registration of
Registrable Securities for sale to the public under the Securities Act, it will
give written notice to all the holders of Registrable Securities promptly of its
intention to do so, describing such securities and specifying the form and
manner and the other relevant facts involved in such proposed registration
(including, without limitation, (x) whether or not such registration will be in
connection with an underwritten offering of Registrable Securities and, if so,
the identity of the managing underwriter and whether such offering will be
pursuant to a "best efforts" or "firm commitment" underwriting and (y) the price
(net of any underwriting commissions, discounts and the like) at which the
Registrable Securities are reasonably expected to be sold) if such disclosure is
acceptable to the managing underwriter. Upon the written request of any such
holder delivered to the Company within 30 calendar days after the receipt of any
such notice (which request shall specify the Registrable Securities intended to
be disposed of by such holder and the intended method of disposition thereof),
the Company will use its reasonable best efforts to effect the registration
under the Securities Act of all of the Registrable Securities that the Company
has been so requested to register; PROVIDED, HOWEVER, that:

               (i) If, at any time after giving such written notice of its
      intention to register any securities and prior to the effective date of
      the registration statement filed in connection with such registration, the
      Company shall determine for any reason not to register such securities,
      the Company may, at its election, give written notice of such
      determination to each holder of Registrable Securities who made a request
      as provided herein and thereupon the Company shall be relieved of its
      obligation to register any Registerable Securities in connection with such
      registration (but not from its obligation to pay the Registration Expenses
      in connection therewith), without prejudice, however, to the rights of the
      holders of the Registrable Securities to request that such registration be
      effected as a registration under Section 6.1; and

                                       36
<PAGE>
              (ii) If such registration involves an Underwritten Offering, all
      holders of Registrable Securities requesting some or all of their
      Registrable Securities to be included in the Company's registration must
      sell that portion of their Registrable Securities to the underwriters
      selected by the Company on the same terms and conditions as apply to the
      Company.

No registration effected under this Section 6.2 shall relieve the Company of its
obligation to effect registration upon request under Section 6.1.

            (b) The Company shall not be obligated to effect any registration of
Registrable Securities under this Section 6.2 incidental to the registration of
any of its securities in connection with mergers, acquisitions, exchange offers,
dividend reinvestment plans or stock option or other employee benefit plans.

            (c) The Registration Expenses incurred in connection with each
registration of Registrable Securities requested pursuant to this Section 6.2
shall be paid by the Company.

            (d) If a registration pursuant to this Section 6.2 involves an
Underwritten Offering and the managing underwriter advises the Company that, in
its opinion, the number of securities proposed to be included in such
registration should be limited due to market conditions, then the Company will
include in such registration (i) first, the securities the Company proposes to
sell, and (ii) second, the number of shares of Common Stock requested to be
included in such registration that, in the opinion of such managing underwriter,
can be sold, such amount to be allocated pro rata among all such requesting
holders on the basis of the class of securities and the relative number of
shares of Registrable Securities, as the case may be, each such holder has
requested to be included in such registration.

            (e) In connection with any Underwritten Offering with respect to
which holders of Registrable Securities shall have requested registration
pursuant to this Section 6.2, the Company shall have the right to select the
managing underwriter with respect to the offering; provided that such managing
underwriter is reasonably acceptable to the First Reserve Stockholders if
Registrable Securities of such First Reserve Stockholders are being registered
in connection therewith.

            (f) Notwithstanding the foregoing, until the earlier of (i) the
second anniversary of the date of a Qualified Public 

                                       37
<PAGE>
Offering and (ii) January 1, 2000, Management Investors and their Permitted
Transferees shall not have piggyback registration if none of the First Reserve
Stockholders are participating in the Public Offering to which this Section 6.2
could apply.

            SECTION 6.3.  REGISTRATION PROCEDURES.

            (a) If and whenever the Company is required to use its reasonable
best efforts to effect or cause the registration of any Registrable Securities
under the Securities Act as provided in Section 6.1 or 6.2, the Company will, as
expeditiously as possible:

               (i) Prepare and, in any event within 60 calendar days after the
      end of the period within which requests for registration may be given to
      the Company, file with the SEC a registration statement with respect to
      such Registrable Securities and use reasonable best efforts to cause such
      registration statement to become and remain effective, PROVIDED that the
      Company may discontinue any registration of its securities that is being
      effected pursuant to Section 6.2 at any time prior to the effective date
      of the registration statement relating thereto.

              (ii) Prepare and file with the SEC such amendments (including
      post-effective amendments) and supplements to such registration statement
      and the prospectus used in connection therewith as may be necessary to
      keep such registration statement effective for a period as may be
      requested by the First Reserve Stockholders (if Registrable Securities of
      such First Reserve Stockholders are being registered) not exceeding nine
      months and to comply with the provisions of the Securities Act with
      respect to the disposition of all Securities covered by such registration
      statement during such period in accordance with the intended methods of
      disposition by the seller or sellers thereof set forth in such
      registration statement, PROVIDED, that before filing a registration
      statement or prospectus relating to the sale of Registrable Securities, or
      any amendments or supplements thereto, the Company will furnish to counsel
      and to each holder of Registrable Securities covered by such registration
      statement or prospectus, copies of all documents proposed to be filed,
      which documents will be subject to the review of such counsel, and the
      Company will give reasonable consideration in good faith to any comments
      of such counsel.

                                       38
<PAGE>
             (iii) Furnish to each holder of Registrable Securities covered by
      the registration statement and to each underwriter, if any, of such
      Registrable Securities, such number of copies of a prospectus and
      preliminary prospectus for delivery in conformity with the requirements of
      the Securities Act, and such other documents, as such Person may
      reasonably request, in order to facilitate the public sale or other
      disposition of the Registrable Securities.

              (iv) Use its reasonable best efforts to register or qualify such
      Registrable Securities covered by such registration statement under such
      other securities or blue sky laws of such jurisdictions as each seller
      shall reasonably request, and do any and all other acts and things which
      may be reasonably necessary or advisable to enable such seller to
      consummate the disposition of the Registrable Securities owned by such
      seller, in such jurisdictions, except that the Company shall not for any
      such purpose be required (A) to qualify to do business as a foreign
      corporation in any jurisdiction where, but for the requirements of this
      Section 6.3(a)(iv), it is not then so qualified, or (B) to subject itself
      to taxation in any such jurisdiction, or (C) to take any action which
      would subject it to general or unlimited service of process in any such
      jurisdiction where it is not then so subject.

               (v) Use its reasonable best efforts to cause such Registrable
      Securities covered by such registration statement to be registered with or
      approved by such other governmental agencies or authorities as may be
      necessary to enable the seller or sellers thereof to consummate the
      disposition of such Registrable Securities.

              (vi) Immediately notify each seller of Registrable Securities
      covered by such registration statement, at any time when a prospectus
      relating thereto is required to be delivered under the Securities Act
      within the appropriate period mentioned in Section 6.3(a)(ii), if the
      Company becomes aware that the prospectus included in such registration
      statement, as then in effect, includes an untrue statement of a material
      fact or omits to state any material fact required to be stated therein or
      necessary to make the statements therein not misleading in the light of
      the circumstances then existing, and, at the request of any such seller,
      deliver a reasonable number of copies of an amended or supplemented
      prospectus as may be necessary so that, as thereafter delivered to the
      purchasers of such Registrable Securities, such prospectus shall not
      include an 

                                       39
<PAGE>
      untrue statement of a material fact or omit to state a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading in the light of the circumstances then existing.

             (vii) Otherwise use its reasonable best efforts to comply with all
      applicable rules and regulations of the SEC and make generally available
      to its security holders, in each case as soon as practicable, but not
      later than 45 calendar days after the close of the period covered thereby
      (90 calendar days in case the period covered corresponds to a fiscal year
      of the Company), an earnings statement of the Company which will satisfy
      the provisions of Section 11(a) of the Securities Act.

            (viii) Use its reasonable best efforts in cooperation with the
      underwriters to list such Registrable Securities on each securities
      exchange as they may reasonably designate.

              (ix) In the event the offering is an Underwritten Offering, use
      its reasonable best efforts to obtain a "cold comfort" letter from the
      independent public accountants for the Company in customary form and
      covering such matters of the type customarily covered by such letters and
      as the First Reserve Stockholders may reasonably request (if Registrable
      Securities of such First Reserve Stockholder are being registered), in
      order to effect an underwritten public offering of such Registrable
      Securities.

               (x) Execute and deliver all instruments and documents (including
      in an Underwritten Offering an underwriting agreement in customary form)
      and take such other actions and obtain such certificates and opinions as
      the First Reserve Stockholders may reasonably request (if Registrable
      Securities of such First Reserve Stockholders are being registered) in
      order to effect an underwritten public offering of such Registrable
      Securities.

              (xi) Make available for inspection by the seller of such
      Registrable Securities covered by such registration statement, by any
      underwriter participating in any disposition to be effected pursuant to
      such registration statement and by any attorney, accountant or other agent
      retained by any such seller or any such underwriter, all pertinent
      financial and other records, pertinent corporate documents and properties
      of the Company, and cause all of the Company's officers, directors and
      employees to supply all information reasonably requested by any such
      seller, 

                                       40
<PAGE>
      underwriter, attorney, accountant or agent in connection with such
      registration statement.

             (xii) Obtain for delivery to the underwriter or agent an opinion or
      opinions from counsel for the Company in customary form and in form and
      scope reasonably satisfactory to such underwriter or agent and their
      counsel.

            (b) Each holder of Registrable Securities will, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 6.3(a)(vi), forthwith discontinue disposition of the Registrable
Securities pursuant to the registration statement and prospectus covering such
Registrable Securities until such holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 6.3(a)(vi).

            (c) If a registration pursuant to or described in Section 6.1 or 6.2
involves an Underwritten Offering, each holder of Registerable Securities
agrees, whether or not such holder's Registrable Securities are included in such
registration, not to effect any public sale or distribution, including any sale
pursuant to Rule 144 under the Securities Act, of any Registrable Securities, or
of any security convertible into or exchangeable or exercisable for any
Registrable Securities (other than as part of such Underwritten Offering),
without the consent of the managing underwriter, during a period commencing
seven calendar days before and ending 180 calendar days (or such lesser number
as the managing underwriter shall designate) after the effective date of such
registration.

            (d) If a registration pursuant to or described in Section 6.1 or 6.2
involves an Underwritten Offering, the Company agrees, if so required by the
managing underwriter, not to effect any public sale or distribution of any of
its equity or debt securities, as the case may be, or securities convertible
into or exchangeable or exercisable for any of such equity or debt securities,
as the case may be, during a period commencing seven calendar days before and
ending 180 calendar days (or such lesser number as the managing underwriter
shall designate) after the effective date of such registration, except for such
Underwritten Offering or except in connection with a stock option plan, stock
purchase plan, savings or similar plan, or an acquisition, merger or exchange
offer.

            (e) If a registration pursuant to or described in Section 6.1 or 6.2
involves an Underwritten Offering, any holder of Registrable Securities
requesting to be included in such 

                                       41
<PAGE>
registration may elect, in writing, prior to the effective date of the
registration statement filed in connection with such registration, not to
register such securities in connection with such registration, unless such
holder has agreed with the Company or the managing underwriter to limit its
rights under this Section 6.3.

            (f) It is understood that in any Underwritten Offering in addition
to any shares of stock (the "initial shares") the underwriters have committed to
purchase, the underwriting agreement may grant the underwriters an option to
purchase up to a number of additional shares of stock (the "option shares")
equal to 15% of the initial shares (or such other maximum amount as the NASD may
then permit), solely to cover overallotments. Shares of stock proposed to be
sold by the Company and the other sellers shall be allocated between initial
shares and option shares as agreed or, in the absence of agreement, pro rata
among the Company and all such Sellers on the basis of the relative number of
shares to be included by each in such registration.

            SECTION 6.4.  INDEMNIFICATION.

            (a) In the event of any registration of any securities of the
Company under the Securities Act pursuant to Section 6.1 or 6.2, the Company
will, and it hereby agrees to, indemnify and hold harmless, to the extent
permitted by law, each seller of any Registrable Securities covered by such
registration statement, each affiliate of such seller and their respective
directors, officers, employees and agents or general and limited partners (and
directors, officers, employees and agents thereof) and, if such seller is a
portfolio or investment fund, its investment advisors or agents, each other
Person who participates as an underwriter in the offering or sale of such
securities and each other Person, if any, who controls such seller or any such
underwriter within the meaning of the Securities Act, as follows:

               (i) against any and all loss, liability, claim, damage or expense
      whatsoever arising out of or based upon an untrue statement or alleged
      untrue statement of a material fact contained in any registration
      statement (or any amendment or supplement thereto), including all
      documents incorporated therein by reference, or the omission or alleged
      omission therefrom of a material fact required to be stated therein or
      necessary to make the statements therein not misleading, or arising out of
      an untrue statement or alleged untrue statement of a material fact
      contained in any preliminary prospectus or prospectus (or any amendment or
      supplement thereto) or the omission or alleged omission 

                                       42
<PAGE>
      therefrom of a material fact required to be stated therein or necessary in
      order to make the statements therein not misleading;

              (ii) against any and all loss, liability, claim, damage and
      expense whatsoever to the extent of the aggregate amount paid in
      settlement of any litigation, or investigation or proceeding by any
      governmental agency or body, commenced or threatened, or of any claim
      whatsoever based upon any such untrue statement or omission, or any such
      alleged untrue statement or omission, if such settlement is effected with
      the written consent of the Company; and

             (iii) against any and all expense reasonably incurred by them in
      connection with investigating, preparing or defending against any
      litigation, or investigation or proceeding by any governmental agency or
      body, commenced or threatened, or any claim whatsoever based upon any such
      untrue statement or omission, or any such alleged untrue statement or
      omission to the extent that any such expense is not paid under
      subparagraph (i) or (ii) above;

Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such seller or any such director, officer,
employee, agent, general or limited partner, investment advisor or agent,
underwriter or controlling Person and shall survive the transfer of such
securities by such seller.

            Notwithstanding the foregoing, the Company shall not be liable to
any person described in Section 6.4(a) in any such case to the extent that any
such loss, liability, claim, damage or expense whatsoever arises out of or is
based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement or amendment or supplement
thereto or in any such preliminary, final or summary prospectus in reliance upon
and in conformity with written information furnished to the Company through an
instrument duly executed by such person specifically stating that it is for use
in the preparation thereof. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such person or the
Company and shall survive the transfer of such securities by such seller.

            (b) The Company may require, as a condition to including any
Registrable Securities in any registration statement filed in accordance with
Section 6.1 or 6.2, that the 

                                       43
<PAGE>
Company shall have received an undertaking reasonably satisfactory to it from
the prospective seller of such Registrable Securities or any underwriter, to
indemnify and hold harmless (in the same manner and to the same extent as set
forth in Section 6.4(a)) the Company and its directors, officers, employees,
agents and controlling Persons with respect to any statement or alleged
statement in or omission or alleged omission from such registration statement,
any preliminary, final or summary prospectus contained therein, or any amendment
or supplement, if such statement or alleged statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such seller or underwriter
specifically stating that it is for use in the preparation of such registration
statement, preliminary, final or summary prospectus or amendment or supplement.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Company or any such director, officer,
employee, agent or controlling Person and shall survive the transfer of such
securities by such seller. In that event, the obligations of the Company and
such sellers pursuant to this Section 6.4 are to be several and not joint;
PROVIDED, HOWEVER, that, with respect to each claim pursuant to this Section,
the Company shall be liable for the full amount of such claim, and each such
seller's liability under this Section 6.4 shall be limited to an amount equal to
the net proceeds (after deducting the underwriting discount and expenses)
received by such seller from the sale of Registrable Securities held by such
seller pursuant to this Agreement.

            (c) Promptly after receipt by an indemnified party hereunder of
written notice of the commencement of any action or proceeding involving a claim
referred to in this Section 6.4, such indemnified party will, if a claim in
respect thereof is to be made against an indemnifying party, give written notice
to such indemnifying party of the commencement of such action; PROVIDED,
HOWEVER, that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligations under this
Section 6.4, except to the extent (not including any such notice of an
underwriter) that the indemnifying party is materially prejudiced by such
failure to give notice. In case any such action is brought against an
indemnified party, unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may exist
in respect of such claim (in which case the indemnifying party shall not be
liable for the fees and expenses of, with respect to the First Reserve
Stockholders, more than one firm of counsel selected by the First Reserve

                                       44
<PAGE>
Stockholders, or with respect to the underwriters, more than one firm of counsel
for the underwriters in connection with any one action or separate but similar
or related actions), the indemnifying party will be entitled to participate in
and to assume the defense thereof, jointly with any other indemnifying party
similarly notified, to the extent that it may wish with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party for
any legal or other expenses subsequently incurred by such indemnifying party in
connection with the defense thereof provided that the indemnifying party will
not agree to any settlement without the prior consent of the indemnified party
(which consent shall not be unreasonably withheld) unless such settlement
requires no more than a monetary payment for which the indemnifying party agrees
to indemnify the indemnified party and includes a full, unconditional and
complete release of the indemnified party, provided, however, that the
indemnified party shall be entitled to take control of the defense of any claim
as to which, in the reasonable judgment of the indemnifying party's counsel,
representation of both the indemnifying party and the indemnified party would be
inappropriate under the applicable standards of professional conduct due to
actual or potential differing interests between them. In the event that the
indemnifying party does not assume the defense of a claim pursuant to this
Section 6.4(c), the indemnified party will have the right to defend such claim
by all appropriate proceedings, and will have control of such defense and
proceedings, and the indemnified party shall have the right to agree to any
settlement without the prior consent of the indemnifying party. Each indemnified
party shall, and shall cause its legal counsel to, provide reasonable
cooperation to the indemnifying party and its legal counsel in connection with
its assuming the defense of any claim, including the furnishing of the
indemnifying party with all papers served in such proceeding. In the event that
an indemnifying party assumes the defense of an action under this Section
6.4(c), then such indemnifying party shall, subject to the provisions of this
Section 6.4, indemnify and hold harmless the indemnified party from any and all
losses, claims, damages or liabilities by reason of such settlement or judgment.

            (d) The Company and each seller of Registerable Securities shall
provide for the foregoing indemnity (with appropriate modifications) in any
underwriting agreement with respect to any registration or other qualification
of securities under any federal or state law or regulation of any governmental
authority.

                                       45
<PAGE>
            SECTION 6.5. CONTRIBUTION. In order to provide for just and
equitable contribution in circumstances under which the indemnity contemplated
by Section 6.4 is for any reason not available or insufficient for any reason to
hold harmless an indemnified party in respect of any losses, claims, damages or
liabilities referred to therein, the parties required to indemnify by the terms
thereof shall contribute to the aggregate losses, liabilities, claims, damages
and expenses of the nature contemplated by such indemnity agreement incurred by
the Company, any seller of Registrable Securities and one or more of the
underwriters, except to the extent that contribution is not permitted under
Section 11(f) of the Securities Act. In determining the amounts which the
respective parties shall contribute, there shall be considered the relative
benefits received by each party from the offering of the Registrable Securities
by taking into account the portion of the proceeds of the offering realized by
each, and the relative fault of each party by taking into account the parties'
relative knowledge and access to information concerning the matter with respect
to which the claim was asserted, the opportunity to correct and prevent any
statement or omission and any other equitable considerations appropriate under
the circumstances. The Company and each Person selling securities agree with
each other that no seller of Registrable Securities shall be required to
contribute any amount in excess of the amount such seller would have been
required to pay to an indemnified party if the indemnity under Section 6.4(b)
were available. The Company and each such seller agree with each other and the
underwriters of the Registrable Securities, if requested by such underwriters,
that it would not be equitable if the amount of such contribution were
determined by pro rata or per capita allocation (even if the underwriters were
treated as one entity for such purpose) or for the underwriters' portion of such
contribution to exceed the percentage that the underwriting discount bears to
the initial public offering price of the Registrable Securities. For purposes of
this Section 6.5, each Person, if any, who controls an underwriter within the
meaning of Section 15 of the Securities Act shall have the same rights to
contribution as such underwriter, and each director and each officer of the
Company who signed the registration statement, and each Person, if any, who
controls the Company or a seller of Registrable Securities within the meaning of
Section 15 of the Securities Act shall have the same rights to contribution as
the Company or a seller of Registrable Securities, as the case may be.

            SECTION 6.6. RULE 144. If the Company shall have filed a
registration statement pursuant to the requirements of Section 12 of the
Exchange Act or a registration statement pursuant to 

                                       46
<PAGE>
the requirements of the Securities Act, the Company covenants that it will file
the reports required to be filed by it under the Securities Act and the Exchange
Act and the rules and regulations adopted by the SEC thereunder (or, if the
Company is not required to file such reports, it will, upon the request of any
holder of Registrable Securities, make publicly available other information),
and it will take such further action as any holder of Registrable Securities may
reasonably request, all to the extent required from time to time to enable such
holder to sell shares of Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by (i) Rule 144
under the Securities Act, as such Rule may be amended from time to time, or (ii)
any similar rule or regulation hereafter adopted by the SEC. Upon the request of
any holder of Registrable Securities, the Company will deliver to such holder a
written statement as to whether it has complied with such requirements,

                            ARTICLE VII. TERMINATION.

            SECTION 7.1.  CERTAIN TERMINATIONS.

            (a) Except to the extent specifically provided elsewhere in this
Agreement, the provisions of Articles II, III, IV and V shall terminate on the
date on which there occurs a Qualified Public Offering.

provided elsewhere in this Agreement, this Agreement shall in any event
terminate with respect to any Securityholder when such Securityholder no longer
owns any shares of Common Stock or Stock Rights.

                          ARTICLE VIII. MISCELLANEOUS.

            SECTION 8.1. SUCCESSORS AND ASSIGNS. Except as provided in Section
4.2 and as otherwise provided herein, all of the terms and provisions of this
Agreement shall be binding upon, shall inure to the benefit of and shall be
enforceable by the respective successors and assigns of the parties hereto. No
Securityholder may assign any of its rights hereunder to any Person other than a
transferee that has complied with the requirements of Sections 4.1 and 4.2 as
provided therein in all respects. The Company may not assign any of its rights
hereunder to any Person other than an affiliate of the Company. If any
transferee of any Securityholder shall acquire any shares of 

                                       47
<PAGE>
Stock or Stock Rights, in any manner, whether by operation of law or otherwise,
such Stock or Stock Rights shall be held subject to all of the terms of this
Agreement, and by taking and holding such Securities such Person shall be
entitled to receive the benefits of and be conclusively deemed to have agreed to
be bound by and to comply with all of the terms and provisions of this
Agreement, provided, however, that any transferee from a Management Investor
shall have only those rights, benefits and obligations of a Management Investor
hereunder.

            SECTION 8.2. AMENDMENT AND MODIFICATION; WAIVER OF COMPLIANCE.

            (a) This Agreement may be amended only by a written instrument duly
executed by the First Reserve Stockholders. No amendment to this Agreement which
adversely affects the rights of the Management Investors hereunder may be
effected without the prior written consent of Management Investors holding a
majority of the shares of Stock or Stock Rights at the time held by the
Management Investors, calculated on the basis of Fully Diluted Common Stock. In
the event of the amendment or modification of this Agreement in accordance with
its terms, the Securityholders shall cause the Board of Directors of the Company
to meet within 30 calendar days following such amendment or modification or as
soon thereafter as is practicable for the purpose of adopting any amendment to
the Certificate of Incorporation and By-Laws of the Company that may be required
as a result of such amendment or modification to this Agreement, and, if
required, proposing such amendments to the Securityholders entitled to vote
thereon, and the Securityholders agree to vote in favor of such amendments.

            (b) Except as otherwise provided in this Agreement, any failure of
any of the parties to comply with any obligation, covenant, agreement or
condition herein may be waived by the party entitled to the benefits thereof
only by a written instrument signed by the party granting such waiver, but such
waiver or failure to insist upon strict compliance with such obligation,
covenant, agreement or condition shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure.

            (c) In the event of any conflict between the provisions of this
Agreement and the provisions of any other agreement, the provisions of this
Agreement shall govern and prevail, except as otherwise provided herein.

            SECTION 8.3. NOTICES. Any notice, request, claim, demand, document
or other communication hereunder to any party 

                                       48

      set forth in the stock records of the Company; and

            SECTION 8.4.  ENTIRE AGREEMENT; GOVERNING LAW.

            (a) This Agreement and the other writings referred to herein or

undertakings among the parties hereto with regard to this subject 

                                       49

matter. The Company represents to the Securityholders that the rights granted to
the holders hereunder do not in any way conflict with and are not inconsistent
with the rights granted or obligations accepted under any other agreement
(including the Certificate of Incorporation) to which the Company is a party.

            (b) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE INTERNAL LAWS OF THE STATE OF DELAWARE (WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICTS OF LAW THEREOF THAT WOULD REQUIRE THE APPLICATION OF THE
LAWS OF ANY JURISDICTION OTHER THAN DELAWARE).

            SECTION 8.5. INJUNCTIVE RELIEF. The Securityholders acknowledge and
agree that a violation of any of the terms of this Agreement will cause the
Securityholders irreparable injury for which adequate remedy at law is not
available. Therefore, the Securityholders agree that each Securityholder shall
be entitled to an injunction, restraining order or other equitable relief from
any court of competent jurisdiction, restraining any Securityholder from
committing any violations of the provisions of this Agreement.

            SECTION 8.6. INSPECTION. For so long as this Agreement shall be in
effect, this Agreement shall be made available for inspection by any
Securityholder at the principal executive offices of the Company.

            SECTION 8.7. HEADINGS. The section and paragraph headings contained
in this Agreement are for reference purposes only and shall not affect in any
way the meaning or interpretation of this Agreement.

            SECTION 8.8. RECAPITALIZATIONS, EXCHANGES, ETC., AFFECTING THE
SECURITIES. The provisions of this Agreement shall apply to the full extent set
forth herein with respect to the Stock and the Stock Rights, and to any and all
equity or debt securities of the Company or any successors or assigns of the
Company (whether by merger, consolidation, sale of assets, or otherwise) which
may be issued in respect of, in exchange for, or in substitution of, such Stock
and Stock Rights or equity or debt securities and shall be appropriately
adjusted for any stock dividends, splits, reverse splits, combinations,
reclassifications, recapitalizations, reorganizations and the like occurring
after the date hereof.

            SECTION 8.9. COUNTERPARTS. This Agreement may be executed in one or
more counterparts, each of which shall be 

                                       50
<PAGE>
deemed an original, but all of which together shall constitute one and the same
instrument.

            SECTION 8.10. ADDITIONAL MANAGEMENT INVESTORS. If the Company shall
at any time issue, grant, sell or otherwise transfer any options, shares of
Common Stock or other equity securities of the Company to any employee of the
Company or its Affiliates then, prior to such issuance such employee and his/her
spouse (if applicable) will become a "Management Investor" party to this
Agreement pursuant to a written instrument in form and substance reasonably
satisfactory to the First Reserve Investors and the Company. Upon execution and
delivery of such written instrument, such employee shall become a "Management
Investor" party to this Agreement and have all of the rights and obligations of

(ii) all payments made by the Companies after June 30, 1996 relating to advances
made by Tenneco and its affiliates (other than the Companies), including, after
the Merger, the Seller and its affiliates; provided, however, that advances by
Tenneco and its affiliates (other than the Companies), including, after the
Merger, by the Seller and its affiliates, from, but not including, June 30,
1996, to the Companies shall be excluded to the extent such advances represent
(x) non-cash charges for general and administrative, corporate overhead and
similar services and/or payment of expenses incurred by the Companies in
connection with the transactions contemplated hereby or other efforts to sell
the Stock, except such expenses incurred by the Companies to assist the Buyer in
connection herewith or (y) amounts or actual charges related to, and/or
provisions for, federal or state income taxes. The Shareholder Advance Balance
set forth in the Statement shall be determined using the same accounting
methods, policies, practices and procedures, with consistent classification,
judgments and estimation methodology as used in determining such amounts for the
purpose of the unaudited consolidated balance sheet of Ventures and its
subsidiaries as of June 30, 1996 and the unaudited consolidated balance sheet of
TGP and its subsidiaries as of June 30, 1996 (collectively, the "Balance
Sheets"), and shall not take into account any changes in circumstances or events
occurring after the close of business on the Closing Date.

               (c) The Statement delivered by the Seller to the Buyer and the
computation of the Closing Shareholder Advance Balance and the Adjusted Purchase
Price annexed thereto shall be conclusive and binding upon the parties unless
the Buyer, within 15 days after receipt by the Buyer of the Statement, notifies
the Seller in writing that the Buyer disputes any of the amounts set forth
therein, specifying the nature of the dispute and the basis therefor. The
parties shall in good faith attempt to resolve any dispute, in which event the
Statement and the computation of the Closing Shareholder Advance Balance and the
Adjusted Purchase Price, as amended to the extent necessary to reflect the
resolution of the dispute, shall be conclusive and binding upon the parties. If
the parties do not reach agreement resolving the dispute within 10 days after
notice is given by the Buyer to the Seller pursuant to the second preceding
sentence, the parties shall submit the dispute to a nationally recognized
independent accounting firm mutually agreeable to the parties, which firm shall
not have had a material relationship with either the Buyer or the Seller or
their respective affiliates within the two years preceding the appointment (the
"Arbiter"), for resolution. If the parties cannot agree on the selection of the
independent accounting firm to act as Arbiter, the parties shall request the
American Arbitration Association to appoint such a firm, and such appointment
shall be conclusive and binding upon the parties. Promptly, but no later than 20
days after its acceptance of its appointment as Arbiter, the Arbiter shall
determine, based solely on presentations by the Buyer and the Seller, and not by
independent review, only those issues in dispute and shall render a report as to
the dispute and the resulting computation of the Statement, the

                                     3
<PAGE>
Closing Shareholder Advance Balance and the Adjusted Purchase Price, which shall
be conclusive and binding upon the parties. In resolving any disputed item, the
Arbiter shall be bound by the provisions of this Agreement governing the
calculation of such amounts. The fees, costs and expenses of the Arbiter (i)
shall be borne by the Buyer in the proportion that the aggregate dollar amount
of such disputed items so submitted that are unsuccessfully disputed by the
Buyer (as finally determined by the Arbiter) bears to the aggregate dollar
amount of such items so submitted and (ii) shall be borne by the Seller in the
proportion that the aggregate dollar amount of such disputed items so submitted
that are successfully disputed by the Buyer (as finally determined by the
Arbiter) bears to the aggregate dollar amount of such items so submitted.
Whether any dispute is resolved by agreement among the parties or by the
Arbiter, changes to the Statement shall be made hereunder only for items as to
which the Buyer has taken exception as provided herein. The Buyer and the Seller
each shall make available to the other (upon the request of the other ) their
respective work papers generated in connection with the preparation or review of
the Statement.

               (d) The Purchase Price shall be increased by the amount of the
Shareholder Advance Balance, if such balance is a positive number, or the
Purchase Price shall be decreased by the amount of the Shareholder Advance
Balance, if such balance is a negative number (the Purchase Price as so
increased or decreased shall be referred to herein as the "Adjusted Purchase
Price"). If the Closing Date Amount is less than the Adjusted Purchase Price,
the Buyer shall pay to TGPL the amount by which the Adjusted Purchase Price
exceeds the Closing Date Amount and, if the Closing Date Amount is more than the
Adjusted Purchase Price, the Seller shall cause TGPL to pay to the Buyer the
amount by which the Closing Date Amount exceeds the Adjusted Purchase Price (the
amount due pursuant to this sentence shall be referred to herein as the
"Purchase Price Adjustment Payment"). Notwithstanding the foregoing, the Closing
Date Amount shall only be adjusted pursuant to this Paragraph (d) to the extent
any such adjustment to the Closing Date Amount would result in an adjustment to
the Closing Date Amount of $500,000 or more.

               (e) The amount of any Purchase Price Adjustment Payment shall
bear interest at an annual rate equal to the reference rate from time to time of
The Chase Bank plus 1% (the "Rate") from and including the Closing Date to, but
not including, the date of payment. Any amount payable as a Purchase Price
Adjustment Payment (plus interest determined pursuant to the immediately
preceding sentence) shall be paid by wire transfer of immediately available
funds to an account designated in writing by the Buyer or the Seller, as the
case may be. Such payment shall be made on the third business day following (i)
the last day on which the Buyer may, pursuant to the first sentence of Section
1.04(c), notify the Seller that it disputes any of the amounts set forth in the
Statement, if there shall have been no dispute between the parties with respect
thereto, or such earlier date as the Buyer shall advise the Seller of the
absence of any dispute, (ii) the

                                     4
<PAGE>
date mutual agreement is reached as to the amount of the Adjusted Purchase
Price, if any, in the event of a dispute that is settled by the parties without
resort to the Arbiter or (iii) the receipt of the report of the Arbiter in the
event of a dispute which is settled by the Arbiter, as applicable.

            1.05. TGP CONSENTS. If the unconditional consents of each of the
General Electric Pension Trust, the GTE Service Corporation Plan for Employees'
Pensions and the Delta Master Trust (collectively, the "TGP Investors") to sell
the issued and outstanding common stock of TGP (the "TGP Stock") pursuant hereto
(the "TGP Consents") are not obtained prior to the Closing Date, the TGP Stock
will not be sold on such date and an amount of $12,700,000 (such sum, the "TGP
Allocated Value") will be withheld from the Closing Date Amount. In such event,
the Seller may notify the Buyer that the Seller desires to continue seeking to
obtain such consents, and the Buyer will use all reasonable efforts to cooperate
with the Seller in connection therewith for a period not to exceed six months
from the Closing Date (the "Interim Period"). If the Seller determines not to
continue to seek such consents, the Seller may terminate this Agreement with
regard to the TGP Stock, and, if so terminated, neither party will have any
further liability or obligation to the other with respect thereto except, to the
extent applicable, pursuant to Section 4.03 and Section 11.09 hereof. During the
Interim Period, the provisions of Articles IV and V hereof will continue to
apply with respect to TGP and its subsidiaries. If at the termination of the
Interim Period, or any date prior thereto, the TGP Consents have been obtained
(the "TGP Closing Date"), on such date the Seller will cause TGPL to sell to the
Buyer, and the Buyer will purchase from TGPL, the TGP Stock, for the TGP
Allocated Value. If at the termination of the Interim Period the TGP Consents
have not been obtained, either the Seller or the Buyer may terminate this
Agreement with regard to the TGP Stock, and, if so terminated, neither party
will have any further liability or obligation to the other with respect thereto
except, to the extent applicable, pursuant to Section 4.03 and Section 11.09
hereof.

            1.06. NPI CONVERSION. If the NPI Conversion for any of the TGP
Investors (as defined in Section 6.11(b)) has not occurred prior to the Closing
Date, at the sole option of the Seller, the TGP Stock will not be sold on such
date and an amount equal to the TGP Allocated Value will be withheld from the
Closing Date Amount. In such event, the Seller may notify the Buyer that the
Seller desires to continue to seek the occurrence of all of the NPI Conversions,
and the Buyer will use all reasonable efforts to cooperate with the Seller in
connection therewith for the Interim Period. If the Seller determines not to
continue to seek the occurrence of all of the NPI Conversions, the Seller may
terminate this Agreement with regard to the TGP Stock, and, if so terminated,
neither party will have any further liability or obligation to the other with
respect thereto except, to the extent applicable, pursuant to Section 4.03 and
Section 11.09 hereof. During the Interim Period, the provisions of Articles IV
and V hereof will continue to apply with respect to TGP and its subsidiaries. If
at the termination of the Interim Period,

                                     5
<PAGE>
or any date prior thereto, all of the NPI Conversions shall have occurred, on
such date the Seller will cause TGPL to sell to the Buyer, and the Buyer will
purchase from TGPL, the TGP Stock, for the TGP Allocated Value. If at the
termination of the Interim Period all of the NPI Conversions shall not have
occurred, either the Seller or the Buyer may terminate this Agreement with
regard to the TGP Stock, and, if so terminated, neither party will have any
further liability or obligation to the other with respect thereto except, to the
extent applicable, pursuant to Section 4.03 and Section 11.09 hereof.

            1.07. TGP STOCK CLOSING ADJUSTMENTS. Notwithstanding anything to the
contrary in this Agreement, if the closing of the acquisition of the TGP Stock
does not occur at the Closing, appropriate adjustments will be made to the
Closing Date Amount, the Statement, the Closing Shareholder Advance Balance, the
Shareholder Advance Balance, the Shareholder Advance Amount and the Adjusted
Purchase Price to reflect the fact that the Buyer is not acquiring the TGP
Stock. At the subsequent closing relating to the acquisition of the TGP Stock
(if any), provisions comparable to the provisions of Sections 1.03 and 1.04 will
be implemented with respect to the acquisition and payment for the TGP Stock.

            1.08. ESCROW CLOSING. Notwithstanding the provisions of Sections
1.05 and 1.06, in the event the TGP Consents are not obtained, or if the NPI
Conversion does not occur, in each case, on or prior to the Closing, the parties
hereto agree to close the acquisition of the TGP Stock in escrow at the Closing
pursuant to an Escrow Agreement, in form, scope and substance reasonably
satisfactory to the Buyer and the Seller.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

            The Seller represents and warrants to the Buyer, as of the date
hereof, as follows:

            2.01. CAPITALIZATION. The authorized capital stock of (i) Ventures
consists of 200 shares of common stock, par value $5.00 per share, of which 200
shares are issued and outstanding and (ii) TGP consists of 200 shares of common
stock, par value $5.00 per share of which 200 shares are issued and outstanding;

issued, fully paid and non-assessable. There are outstanding no securities
convertible into, exchangeable for, or carrying the right to acquire, equity
securities of the Companies, or subscriptions, warrants, options, rights or
other arrangements or commitments obligating the Companies to issue or dispose
of any of their respective equity securities and/or partnership interests or any
ownership interest

                                     6
<PAGE>
therein. The sale and delivery of the Stock to the Buyer pursuant to Article I
hereof will vest in the Buyer legal and valid title to the Stock, free and clear
of all liens, security interests or other encumbrances ("Encumbrances") (other
than Encumbrances created by the Buyer).

            2.02. LITIGATION. There is no action or proceeding in any court or
before any governmental authority ("Litigation") pending or, to the Seller's
knowledge, threatened against the Seller or Tenneco, or any of their respective
affiliates, any Company or any of the subsidiaries of any of the Companies,
(collectively, the "Subsidiaries") with respect to which there is a reasonable
likelihood of a determination which would have a material adverse affect on the
ability of the Seller to perform its obligations under this Agreement. Neither
the Seller, nor Tenneco, nor any of their respective affiliates, is subject to
any outstanding orders, rulings, judgments or decrees which would have a
material adverse effect on the ability of the Seller to perform its obligations
under this Agreement.

            2.03. CORPORATE POWER AND AUTHORITY; EFFECT OF AGREEMENT. Each of
the Seller, TGPL, and each Company is a corporation duly organized, validly

and has all requisite corporate power and authority to execute, deliver and
perform this Agreement and to consummate the transactions contemplated hereby.
The execution, delivery and performance by the Seller of this Agreement and the
consummation by the Seller of the transactions contemplated hereby have been
duly authorized by all necessary corporate action on the part of the Seller.
This Agreement has been duly and validly executed and delivered by the Seller
and constitutes the valid and binding obligation of the Seller, enforceable
against the Seller, in accordance with its terms, except to the extent that such
enforceability (i) may be limited by bankruptcy, insolvency, reorganization,

(ii) is subject to general principles of equity. The execution, delivery and
performance by the Seller of this Agreement and the consummation by the Seller
of the transactions contemplated hereby will not, with or without the giving of
notice or the lapse of time, or both, (x) violate any provision of law, rule or
regulation to which the Seller, TGPL, any Company or any of the Subsidiaries is
subject, (y) violate any order, judgment or decree applicable to the Seller,
TGPL, any Company or any of the Subsidiaries or (z) violate any provision of the
Certificate of Incorporation or the By-laws or other constituent documents of
the Seller, TGPL, any Company or any of the Subsidiaries; except, in each case,
for violations which in the aggregate would not materially hinder or impair the
consummation of the transactions contemplated hereby.

            2.04. CONSENTS. No consent, approval or authorization of, or
exemption by, or filing with, any governmental authority is required to be
obtained or made by the Seller in connection with the execution, delivery and
performance by the Seller of this

                                     7
<PAGE>
Agreement or the taking by the Seller of any other action contemplated hereby,
except where the failure to obtain such consent, approval, authorization or
exemption or the failure to so file, as applicable, does not have a material
adverse effect on the business or financial condition of the Companies and the
Subsidiaries taken as a whole (a "Material Adverse Effect").

            2.05. INTERCOMPANY AGREEMENTS. At the Closing, except as set forth
in Schedule 2.05, to the extent the agreements specified in Schedule 2.05 are
based on market terms, and except with respect to the Transitional Services
Agreement (as defined in Section 7.05), all intercompany agreements between the
Seller and its affiliates, other than the Companies, on the one hand, and the
Companies, on the other hand, shall be canceled and be of no force and effect.

            2.06. DISCLAIMER. NOTWITHSTANDING ANYTHING CONTAINED IN ANY OTHER
PROVISION OF THIS AGREEMENT, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO THAT
THE SELLER IS MAKING NO REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR
IMPLIED, BEYOND THOSE EXPRESSLY GIVEN IN THIS AGREEMENT, AND IT IS UNDERSTOOD
THAT, EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES EXPRESSLY GIVEN IN THIS
AGREEMENT, THE BUYER TAKES THE STOCK AND THE BUSINESS AND ASSETS OF THE
COMPANIES AND/OR THE SUBSIDIARIES AS IS AND WHERE IS. WITHOUT LIMITING THE
GENERALITY OF THE IMMEDIATELY FOREGOING, EXCEPT FOR THOSE REPRESENTATIONS AND
WARRANTIES EXPRESSLY GIVEN IN THIS AGREEMENT, THE SELLER HEREBY (A) EXPRESSLY
DISCLAIMS AND NEGATES ANY REPRESENTATION OR WARRANTY, EXPRESSED OR IMPLIED, AT
COMMON LAW, BY STATUTE OR OTHERWISE, RELATING TO (i) THE CONDITION OF THE ASSETS
OF THE COMPANIES AND/OR THE SUBSIDIARIES (INCLUDING WITHOUT LIMITATION ANY
IMPLIED OR EXPRESSED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE), OR (ii) ANY INFRINGEMENT BY ANY COMPANY OR ANY SUBSIDIARY OR ANY OF
THEIR RESPECTIVE AFFILIATES OF ANY PATENT OR PROPRIETARY RIGHT OF ANY THIRD
PARTY; AND (B) NEGATE ANY RIGHTS OF THE BUYER UNDER STATUTES TO CLAIM DIMINUTION
OF CONSIDERATION AND ANY CLAIMS BY THE BUYER FOR DAMAGES BECAUSE OF REDHIBITORY
VICES OR DEFECTS, WHETHER KNOWN OR UNKNOWN, IT BEING THE INTENTION OF THE SELLER
AND THE BUYER THAT THE BUSINESS AND ASSETS OF THE COMPANIES AND/OR THE
SUBSIDIARIES ARE TO BE ACCEPTED BY THE BUYER IN THEIR PRESENT CONDITION AND
STATE OF REPAIR.

            3.05. LITIGATION. There is no Litigation pending or, to the Buyer's

material adverse effect on the ability of the Buyer to perform its obligations
under this Agreement.

            3.06. PURCHASE FOR INVESTMENT. The Buyer is purchasing the Stock for
investment and not with a view to any public resale or other distribution
thereof, except in compliance with applicable securities laws. The Buyer
acknowledges that it has received, or has had access to, all information which
it considers necessary or advisable to enable it to make a decision concerning
its purchase of the Stock.

                                  ARTICLE IV

                           COVENANTS OF THE SELLER

            The Seller hereby covenants and agrees with the Buyer as follows:

            4.01. COOPERATION BY THE SELLER. From the date hereof and prior to
the Closing, the Seller will use its reasonable efforts, and will cooperate with
the Buyer, to secure all necessary consents, approvals, authorizations,
exemptions and waivers from third parties (excluding consents, approvals,
authorizations, exemptions and waivers required from third parties pursuant to
the terms of any agreement, contract or commitment (whether or not in writing)
to which any Company or any Subsidiary is a party or by which their respective
properties are bound (collectively, "Commitments"), as shall be required in
order to enable the Seller and TGPL to effect the transactions contemplated
hereby, and will otherwise use its reasonable efforts to cause the consummation
of such transactions in accordance with the terms and conditions hereof.

            4.02. CONDUCT OF BUSINESS. Except as may be otherwise contemplated
by this Agreement, or except as the Buyer may otherwise consent to in writing
(which consent shall not be unreasonably withheld), from the date hereof through
the Closing, the Seller will not take any action to cause the Companies to
operate their respective businesses or purchase, or sell or otherwise dispose
of, material assets outside the ordinary course of business. Notwithstanding
anything to the contrary in this Agreement, until the close of business on the
business day immediately preceding the Closing Date,

                                     10
<PAGE>
the Seller shall be entitled to withdraw any and all cash from the Companies and
the Subsidiaries; provided, any such withdrawals must be effected by means of
reductions of the Shareholder Advance Balance. In addition, the Seller shall be
entitled to cause the Companies and the Subsidiaries to transfer the Marks (as
defined in Section 5.05(b)) to the Seller or one of its affiliates (other than
the Companies and the Subsidiaries).

            4.03. ACCESS. (a) From the date hereof and prior to the Closing, the
Seller shall provide the Buyer and the Financing Sources with such information
as the Buyer or the Financing Sources may from time to time reasonably request
with respect to any Company, the Subsidiaries and the transactions contemplated
by this Agreement, and shall provide the Buyer and the Financing Sources and
their respective representatives reasonable access during regular business hours
and upon reasonable notice to the properties, books and records of each Company
and each of the Subsidiaries as the Buyer or the Financing Sources may from time
to time reasonably request; PROVIDED, HOWEVER, that the Seller shall not be
obligated to provide the Buyer or the Financing Sources with any information
relating to trade secrets or which would violate any law, rule or regulation or
term of any Commitment, or if the provision thereof would adversely affect the
ability of the Seller or any of its affiliates (including any Company and the
Subsidiaries) to assert attorney-client, attorney work product or other similar
privilege. Any disclosure whatsoever during such investigation by the Buyer or
the Financing Sources shall not constitute an enlargement of or additional
representations or warranties of the Seller beyond those specifically set forth
in this Agreement.

               (b) (i) The Buyer shall, and shall cause its representatives and
the Financing Sources and their representatives, to keep confidential all
information and records, whether prepared by the Seller, its advisors or
otherwise, and whether written or oral, which were obtained, directly or
indirectly, by the Buyer, the Financing Sources or their respective
representatives concerning the business of the Companies and/or the Subsidiaries
("Confidential Information"). The Buyer shall, and shall cause its
representatives, the Financing Sources and their respective representatives to,
use Confidential Information solely in connection with its analysis and review
of the transactions contemplated by this Agreement or in connection with
operating the business of the Companies and the Subsidiaries.

                        (ii) The Buyer may disclose Confidential Information to
(x) the Financing Sources and (y) any of its and the Financing Sources'
respective directors, officers, employees, agents and advisors (each a
"Representative" and, collectively, the "Representatives") who need to know such
Confidential Information for the purpose of assisting the Buyer and the
Financing Sources in connection with the transactions contemplated by this
Agreement; PROVIDED, HOWEVER, that prior to making such disclosure, the Buyer
shall advise the Financing Sources and each such Representative of the Buyer's
obligations under this Section 4.03(b) and the Buyer shall

                                     11
<PAGE>
be responsible for any breach of this Agreement by the Financing Sources or any
such Representative. The Buyer may disclose Confidential Information if required
by legal process or by operation of applicable law; PROVIDED, HOWEVER, that the
Buyer shall first promptly advise and consult with the Seller and its counsel
concerning the information the Buyer proposes to disclose. The Seller shall have
the right to seek an appropriate protective order or other remedy concerning the
Confidential Information the Buyer proposes to disclose and the Buyer will
cooperate with the Seller to obtain such protective order. In the event that
such protective order or other remedy is not obtained by the Seller, the Buyer
will disclose only that portion of the Confidential Information which, in the
written opinion of the Buyer's counsel, the Buyer is legally required to
disclose, and the Buyer will use its best efforts to obtain assurances that
confidential treatment will be accorded to such information.

                        (iii) The Buyer's obligations under clauses (i) and (ii)
of this Section 4.03(b) do not apply to information which (A) at the time of
disclosure is generally available to and known by the public other that as a
result of disclosure in violation of clause (i) or (ii) of this Section 4.03(b)
or (B) was or becomes available to the Buyer on a non-confidential basis from a
source other than the Seller or its agents or advisors; PROVIDED, HOWEVER, that
such source is not bound by a confidentiality agreement or obligation of secrecy
to the Seller in respect thereof.

                        (iv) In the event that the transaction contemplated
hereby is not consummated, all Confidential Information whether or not then in
the Buyer's possession, and any copies thereof, or notes or extracts therefrom
shall be returned to the Seller, without retaining any copies thereof, and the
Buyer shall destroy, as soon as practicable, all copies of any analyses,
studies, compilations or other documents prepared by the Buyer or any of its
Representatives to the extent that they contain, reflect or are generated from
any Confidential Information.

                        (v) The Buyer acknowledges and agrees that any breach by
it of the provisions of this Section 4.03(b) will cause the Seller irreparable
injury and damage, for which the Seller cannot be adequately compensated in
damages. The Buyer, therefore, expressly agrees that the Seller shall be
entitled to seek injunctive relief and/or other equitable relief to prevent any
anticipatory breach or continuing breach of the provisions of this Section
4.03(b), or any part thereof, and to secure their enforcement. Nothing herein
shall be construed as a waiver by the Seller of any right it may now have or
hereafter acquire to monetary damages by reason of any injury to its property,
business or reputation or otherwise arising out of any wrongful act or omission
of the Buyer under the provisions of this Section 4.03(b).

            4.04. FURTHER ASSURANCES. At any time or from time to time after the
Closing, the Seller shall, at the request of the Buyer and at the Buyer's
expense, execute

                                     12
<PAGE>
and deliver any further instruments or documents and take all such further
action as the Buyer may reasonably request in order to evidence the consummation
of the transactions contemplated hereby.

            4.05. CONTRIBUTION OF PROPERTY. At or prior to the Closing, the
Seller shall, or shall cause Tenneco and/or TGPL to, contribute to the
Companies, "AS IS, WHERE IS" and without warranties, express or implied, all
rights, title and interest in and to the furniture, fixtures and equipment
located in the Companies' office space at 1100 Louisiana, Houston, Texas 77002
and used in connection with the business of the Companies as of the date hereof;
provided that the Seller shall not be required to, or shall not cause Tenneco or

that, except as specified in Section 1.05, no representation, warranty or

                                 TAX MATTERS

            6.01. TAX INDEMNIFICATION BY THE SELLER. (a) The Seller shall be
liable for, and shall indemnify the Buyer and its affiliates and hold them
harmless from and against, any (i) Income Taxes arising out of or attributable
to any consolidated, combined or unitary Income Tax Return filed or required to
be filed by the Seller, Tenneco or any Related Party which includes the
Companies and/or the Subsidiaries (without giving effect to any reserves with
respect thereto), including, without limitation, any liability of the Companies
and/or the Subsidiaries for Income Taxes under Section 1.1502-6 of the Treasury
Regulations (or any analogous provision of state, local or foreign law), (ii)
Income Taxes (other than those described in clause (i) above) of the Companies
and/or the Subsidiaries for taxable periods or portions of taxable periods
ending on or before the Closing Date to the extent such Income Taxes exceed any
reserves for such Income Taxes included in the Statement (other than reserves
for deferred Income Taxes), and (iii) subject to Section 6.07, any loss, damage,
liability or expense, including, but not limited to, reasonable fees for
attorneys and other outside consultants, incurred in connection with Income
Taxes described in (i) and (ii) in this Section 6.01(a).

               (b) Payments required under this Section 6.01 shall be made
within 30 days of the Buyer furnishing the Seller with written evidence that the
Buyer has paid such amounts or such amounts are due and payable to a Taxing
Authority.

            6.02. APPORTIONMENT OF TAXES. In order to apportion appropriately
any Income Taxes relating to any Straddle Period, the parties hereto shall, to
the extent permitted under applicable law, elect with the relevant Tax Authority
to treat for all purposes, the Closing Date as the last day of the taxable year
or period of the Companies and/or the Subsidiaries, and such period shall be
treated as a short taxable year and a PreClosing Period for purposes of this
Article VI. In any case where applicable law does not permit a Company or a
Subsidiary to treat the Closing Date as the last day of the taxable year or
period of such Company or Subsidiary with respect to Income Taxes that are
payable with respect to a Straddle Period, the portion of any such Income Taxes
that are

                                     17
<PAGE>
allocable to the portion of the taxable year ending on the Closing Date shall be
deemed to be equal to the amount which would be payable if the taxable year or
period ended on the Closing Date (except that, solely for purposes of
determining the marginal tax rate applicable to income or receipts during such
period in a jurisdiction in which such tax rate depends upon the level of income
or receipts, annualized income or receipts may be taken into account, if
appropriate, for an equitable sharing of such Income Taxes).

            6.03. FILING RESPONSIBILITY. (a) With respect to jurisdictions in
which the Companies are required to file a consolidated, combined or unitary
Income Tax Return with the Seller, Tenneco or any Related Party, or (i) are
eligible to file a consolidated, combined or unitary Income Tax Return with the
Seller, Tenneco or any Related Party and (ii) have filed a consolidated,
combined or unitary Income Tax Return with the Seller, Tenneco or any Related
Party in the most recent taxable period for which a Return was due, the Seller
shall include, or cause to be included, the Companies and the Subsidiaries in
such Returns for all taxable periods ending on or prior to the Closing Date
("PreClosing Tax Periods") and all taxable periods beginning prior to and ending
after the Closing Date ("Straddle Periods"); provided, that in the case of a
Straddle Period, the Companies and the Subsidiaries shall not be included in
such Returns for periods after the Closing Date. The Seller shall timely prepare
and file, or cause to be timely prepared and filed, all such Returns. With
respect to all other Income Tax Returns for Pre-Closing Tax Periods, the Seller
shall timely prepare, or cause to be timely prepared, and deliver to the Buyer,
and the Buyer shall cause to be timely filed, all such Income Tax Returns. The
Seller shall timely prepare and file, or cause to be timely prepared and filed,
all NonIncome Tax Returns the due date for filing of which is on or before the
Closing Date. All Returns prepared pursuant to this Section 6.03(a) shall be
prepared or completed in a manner consistent with prior practice of the Seller
and/or the Related Party concerning the income, properties or operations of the
Companies and the Subsidiaries (including elections and accounting methods and
conventions), except as otherwise required by law, and in the case of Returns
prepared in accordance with the second preceding sentence, shall be subject to
the Buyer's review and approval (which approval shall not be unreasonably
withheld). The Seller shall timely pay, or cause to be timely paid, when due,
all Taxes relating to the Returns which it is required to prepare and file
pursuant to this Section 6.03(a). The Seller shall pay, or cause to be paid, to
the Buyer, all Income Taxes relating to Returns which it is required to prepare
and deliver to the Buyer for filing pursuant to this Section 6.03(a) within 10
days prior to the date on which the related Tax liability is due.

               (b) The Buyer shall prepare and file, subject to the Seller's
review and approval (which approval shall not be unreasonably withheld), all
Income Tax Returns of the Companies and the Subsidiaries for any Straddle Period
with respect to which the Seller does not have filing responsibility pursuant to
Section 6.03(a). Except as otherwise required by law, such Returns shall be
prepared or completed in a manner consistent with

                                     18
<PAGE>
prior practice of the Seller concerning the income, properties or operations of
the Companies and the Subsidiaries (including elections and accounting methods
and conventions). Any Income Taxes of the Companies and the Subsidiaries payable
pursuant to such Returns shall be apportioned between the Seller, on the one
hand, and the Buyer, on the other hand, in accordance with the principles of
Treasury Regulation Section 1.1502-76(b) applied to the portion of such period
ending on the Closing Date and the portion of such period beginning on the day
following the Closing Date, respectively. Any amounts apportioned to the Seller
pursuant to the preceding sentence shall be paid by the Seller to the Buyer not
later than 5 days prior to the date on which the related Tax liability is due.
The Buyer shall prepare and file all non-Income Tax Returns the due date for
filing of which is after the Closing Date. The Buyer shall timely pay when due
all Taxes relating to the Returns which it is required to file pursuant to this
Section 6.03(b).

            6.04. REFUNDS AND CARRYBACKS. (a) The Seller shall be entitled to
any refunds of Income Taxes attributable to the Companies and/or the
Subsidiaries (including refunds paid by means of credit against other or future
income) for a Pre-Closing Period or the portion of a Straddle Period ending on
or before the Closing Date other than refunds arising from a carryback of a loss
or credit from any period other than a PreClosing Tax Period.

               (b) The Buyer shall forward to the Seller any refunds to which
the Seller is entitled (pursuant to the terms of this Section 6.04) within 5
days after receipt thereof. In the case of a refund received in the form of a
credit against other or future Tax liabilities, reimbursement in respect of such
refund shall be due on the due date for payment of the Taxes against which such
refund has been credited.

               (c) Nothing in this Agreement shall require the Seller to file a
carryback claim or amended Tax Return on behalf of the Buyer. In the case of all
Tax Returns (other than Tax Returns filed by the Company on a separate basis),
the Buyer agrees to elect to relinquish its entire carryback period with respect
to any loss occurring for a period ending after the Closing Date.

            6.05. COOPERATION. After the Closing Date, each of the Buyer and the
Seller shall make available to the other, as reasonably requested, and to any
Taxing Authority, all information, records and documents relating to Tax
liabilities or potential Tax liabilities relating to the Companies and/or the
Subsidiaries and shall preserve all such information, records and documents
until the expiration of any applicable statute of limitations or extension
thereof.

            6.06.  TAX SHARING.  Any and all existing Tax sharing, allocation,
compensation or like agreements or arrangements that include any Company or any

                                     19
<PAGE>
Subsidiary shall be terminated with respect to the applicable Company or
Subsidiary as of the Closing Date without liability to the applicable Company or
Subsidiary and shall have no further effect for any taxable year.

            6.07 AUDITS. The Buyer shall promptly notify the Seller in writing
upon receipt of notice of any pending or threatened Income Tax audits or
assessments which may affect the Tax liabilities of any Company or any
Subsidiary relating to a period with respect to which the Seller would be liable
pursuant to Section 6.01; PROVIDED, HOWEVER, that a failure to give such notice
will not affect the Buyer's or the Companies' and/or the Subsidiaries' rights to
indemnification hereunder, except to the extent, if any, that, but for such
failure, the Seller could have avoided the Tax liability in question. The Seller
shall represent its own interests and the interests of the Companies and the
Subsidiaries in any Tax matter, including any audit, examination, assessment,
notice of deficiency or other adjustment or proposed adjustment, or
administrative or judicial proceeding, the settlement of any of the foregoing,
or the filing of any amended return (a "Tax Matter"), involving an Income Tax
liability relating to a period with respect to which the Seller would be liable
pursuant to Section 6.01 and to employ counsel of its choice at its expense;
PROVIDED, HOWEVER, that the Buyer shall have the right to participate at its own
expense, and its consent shall be required prior to settlement, which consent
shall not be unreasonably withheld, in any such Tax Matter that could have a
material adverse effect on the amount or timing of any Tax of the Buyer or any
of its affiliates. Notwithstanding the foregoing, the Buyer shall represent its
own interest and the interests of the Companies and the Subsidiaries in any Tax
Matters involving an Income Tax liability relating to a period with respect to
which the Buyer has filing responsibility pursuant to Section 6.03(b); PROVIDED,
HOWEVER, that the Seller shall have the right to participate at its own expense,
and its consent shall be required prior to settlement, which consent shall not
be unreasonably withheld, in any such Tax Matter that could have a material
adverse effect on the amount or timing of any Tax of the Seller. The Buyer and
the Seller and their respective affiliates shall cooperate fully with each other
and their respective counsel in the defense or compromise of any Tax Matter
including, without limitation, the provision of any necessary powers of
attorney. Notwithstanding anything herein to the contrary, the Seller shall have
the exclusive right to control, settle and resolve any Tax Matter relating to
the NPI Conversion.

                                TERMS OF FACILITY

            2.1 REVOLVING LINE OF CREDIT. (a) Upon the terms and conditions
(including, without limitation, the right of the Lender to decline to make any
Loan so long as any Default or Event of Default exists) and relying on the
representations and warranties contained in this Agreement, the Lender agrees,
during the Commitment Period, to make Loans, in immediately available funds at
the Applicable Lending Office or the Principal Office, to or for the benefit of
the Borrower, from time to time on any Business Day designated by the Borrower
following receipt by the Lender of a Borrowing Request; provided, however, no
Loan shall exceed the then existing Available Commitment.

            (b) Subject to the terms of this Agreement, during the Commitment
Period, the Borrower may borrow, repay, and reborrow and convert Loans of one
type or with one Interest Period into Loans of another type or with a different
Interest Period. Except for prepayments made pursuant to Section , each
borrowing, conversion, and prepayment of principal of Loans shall be in an
amount at least equal to $100,000. Each borrowing, prepayment, or conversion of
or into a Loan of a different type or, in the case of

                                      16
<PAGE>
a Fixed Rate Loan, having a different Interest Period, shall be deemed a
separate borrowing, conversion, and prepayment for purposes of the foregoing,
one for each type of Loan or Interest Period. Anything in this Agreement to the
contrary notwithstanding, the aggregate principal amount of LIBO Rate Loans
having the same Interest Period shall be at least equal to $100,000; and if any
LIBO Rate Loan would otherwise be in a lesser principal amount for any period,
such Loan shall be a Floating Rate Loan during such period.

            (c) The Loans shall be made and maintained at the Applicable Lending
Office or the Principal Office and shall be evidenced by the Note.

            2.2   USE OF LOAN PROCEEDS.  Proceeds of all Loans shall
be used solely to fund the purchase of production payments on Oil
and Gas Properties subsequent to the Closing Date.

            2.3 INTEREST. Subject to the terms of this Agreement (including,
without limitation, Section ), interest on the Loans shall accrue and be payable
at a rate per annum equal to the Floating Rate for each Floating Rate Loan and
the Adjusted LIBO Rate for each LIBO Rate Loan. Interest on all Floating Rate
Loans 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) during the period for which payable. Interest on all LIBO Rate 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) during the period for which
payable. Notwithstanding the foregoing, interest on past-due principal and, to
the extent permitted by applicable law, past-due interest, shall accrue at the
Default Rate, 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) during the period for which payable, and shall be payable upon demand by
the Lender at any time as to all or any portion of such interest. In the event
that the Borrower fails to select the duration of any Interest Period for any
Fixed Rate Loan within the time period and otherwise as provided herein, such
Loan (if outstanding as a Fixed Rate Loan) will be automatically converted into
a Floating Rate Loan on the last day of the then current Interest Period for
such Loan or (if outstanding as a Floating Rate Loan) will remain as, or (if not
then outstanding) will be made as, a Floating Rate Loan. Interest provided for
herein shall be calculated on unpaid sums actually advanced and outstanding
pursuant to the terms of this Agreement and only for the period from the date or
dates of such advances until repayment.

            2.4 REPAYMENT OF LOANS AND INTEREST. Accrued and unpaid interest on
each outstanding Floating Rate Loan shall be due and payable monthly commencing
on the first day of July, 1996, and

                                      17
<PAGE>
continuing on the first day of each calendar month thereafter while any Floating
Rate Loan remains outstanding, the payment in each instance to be the amount of
interest which has accrued and remains unpaid in respect of the relevant Loan.
Accrued and unpaid interest on each outstanding Fixed Rate Loan shall be due and
payable on the last day of the Interest Period for such Fixed Rate Loan and, in
the case of any Interest Period in excess of three months, on the day of the
third calendar month following the commencement of such Interest Period
corresponding to the day of the calendar month on which such Interest Period
commenced, the payment in each instance to be the amount of interest which has
accrued and remains unpaid in respect of the relevant Loan. The Loan Balance,
together with all accrued and unpaid interest thereon, shall be due and payable
at Final Maturity. At the time of making each payment hereunder or under the
Note, the Borrower shall specify to the Lender the Loans or other amounts
payable by the Borrower hereunder to which such payment is to be applied. In the
event the Borrower fails to so specify, or if an Event of Default has occurred
and is continuing, the Lender may apply such payment as it may elect in its sole
discretion.

            2.5 OUTSTANDING AMOUNTS. The outstanding principal balance of the
Note reflected by the notations by the Lender on its records shall be deemed
rebuttably presumptive evidence of the principal amount owing on the Note. The
liability for payment of principal and interest evidenced by the Note shall be
limited to principal amounts actually advanced and outstanding pursuant to this
Agreement and interest on such amounts calculated in accordance with this
Agreement.

            2.6 TIME, PLACE, AND METHOD OF PAYMENTS. All payments required
pursuant to this Agreement or the Note shall be made in lawful money of the
United States of America and in immediately available funds, shall be deemed
received by the Lender on the next Business Day following receipt if such
receipt is after 2:00 p.m., Central Standard or Daylight Savings Time, as the
case may be, on any Business Day, and shall be made at the Principal Office.
Except as provided to the contrary herein, if the due date of any payment
hereunder or under the Note 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.

            2.7 BORROWING BASE DETERMINATIONS. (a) The Borrowing Base as of the
Closing Date is acknowledged by the Borrower and the Lender to be $9,000,000.

            (b) The Borrowing Base shall be redetermined semi-annually beginning
November 1, 1996, on the basis of information supplied by the Borrower in
compliance with the provisions of this Agreement, including, without limitation,
Reserve Reports, and all

                                      18
<PAGE>
other information available to the Lender. Notwithstanding the foregoing, the
Lender may at its discretion redetermine the Borrowing Base at any time and from
time to time.

            (c) Upon each determination of the Borrowing Base by the Lender, the
Lender shall notify the Borrower orally (confirming such notice promptly in
writing) of such determination, and the Borrowing Base so communicated to the
Borrower shall become effective upon such written notification and shall remain
in effect until the next subsequent determination of the Borrowing Base.

            (d) The Borrowing Base shall represent the determination by the
Lender, in accordance with the applicable definitions and provisions herein
contained and its customary lending practices for loans of this nature, of the
value, for loan purposes, of the Mortgaged Properties, subject, in the case of
any increase in the Borrowing Base, to the credit approval process of the
Lender. Furthermore, the Borrower acknowledges that the determination of the
Borrowing Base contains an equity cushion (market value in excess of loan
value), which is acknowledged by the Borrower to be essential for the adequate
protection of the Lender. The Borrowing Base shall be determined by using the
Lender's then current engineering and credit standards.

            2.8 MANDATORY PREPAYMENTS. If at any time the Loan Balance exceeds
the Borrowing Base then in effect, the Borrower shall, within 45 days of notice
from the Lender of such occurrence, (a) prepay, or make arrangements acceptable
to the Lender for the prepayment of, the amount of such excess for application
on the Loan Balance, (b) provide additional collateral, of character and value
satisfactory to the Lender in its sole discretion, to secure the Obligations by
the execution and delivery to the Lender of security instruments in form and
substance satisfactory to the Lender, or (c) effect any combination of the
alternatives described in clauses (a) and (b) of this Section and acceptable to
the Lender in its sole discretion. In the event any prepayments are made on any
production payment, the Borrower will, within 5 business days of such
prepayment, reduce the amount outstanding hereunder by the principal amount so
prepaid. Such prepayments will not reduce the amount of the Borrowing Base.

            2.9 VOLUNTARY PREPAYMENTS AND CONVERSIONS OF LOANS. Subject to
applicable provisions of this Agreement, the Borrower shall have the right at
any time or from time to time to prepay Loans and to convert Loans of one type
or with one Interest Period into Loans of another type or with a different
Interest Period; provided, however, that (a) the Borrower shall give the Lender
notice of each such prepayment or conversion of all or any portion of a Fixed
Rate Loan no less than two Business Days prior to prepayment or conversion, (b)
any Fixed Rate Loan may be prepaid or converted only on the last day of an
Interest Period for such Loan,

                                      19
<PAGE>
(c) the Borrower shall pay all accrued and unpaid interest on the amounts
prepaid or converted, and (d) no such prepayment or conversion shall serve to
postpone the repayment when due of any Obligation.

            2.10 COMMITMENT FEE. In addition to interest on the Note as provided
herein and the Engineering Fees and Facility Fees payable hereunder and to
compensate the Lender for maintaining funds available, the Borrower shall pay to
the Lender, in immediately available funds, on the first day of July, 1996, and
on the first day of each third calendar month thereafter during the Commitment
Period, a fee in the amount of one-half percent (1/2%) per annum, calculated 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), on the average
daily amount of the Available Commitment during the preceding quarterly period.

            2.11 ENGINEERING FEE. In addition to interest on the Note as
provided herein and the Commitment Fees and Facility Fees payable hereunder and
to compensate the Lender for the costs of evaluating the Mortgaged Properties
and reviewing the Reserve Reports, the Borrower shall pay to the Lender, in
immediately available funds, on the date of each redetermination of the
Borrowing Base each November and June during the term hereof, an engineering fee
in the amount of $10,000 and on each additional redetermination of the Borrowing
Base the actual cost to Lender of such redetermination.

            2.12 FACILITY FEE. In addition to interest on the Note as provided
herein and Commitment Fees and Engineering Fees payable hereunder and to
compensate the Lender for the costs of the extension of credit hereunder, the
Borrower shall pay to the Lender on the Closing Date, in immediately available
funds, a facility fee in the amount of $22,500. One-half of such fee was paid
upon the acceptance of the preliminary term sheet and the remaining one-half
shall be paid on the Closing Date.

            2.13 LOANS TO SATISFY OBLIGATIONS OF BORROWER. The Lender may, but
shall not be obligated to, make Loans for the benefit of the Borrower and apply
proceeds thereof to the satisfaction of any condition, warranty, representation,
or covenant of the Borrower contained in this Agreement or any other Loan
Document. Any such Loan shall be evidenced by the Note and shall be made as a
Floating Rate Loan.

            2.14 SECURITY INTEREST IN ACCOUNTS; RIGHT OF OFFSET. As security for
the payment and performance of the Obligations, the Borrower hereby transfers,
assigns, and pledges to the Lender and grants to the Lender a security interest
in all funds of the Borrower now or hereafter or from time to time on deposit
with the Lender, with such interest of the Lender to be retransferred,

                                      20
<PAGE>
reassigned, and/or released by the Lender, as the case may be, at the expense of
the Borrower upon payment in full and complete performance by the Borrower of
all Obligations. All remedies as secured party or assignee of such funds shall
be exercisable by the Lender upon the occurrence of any Event of Default,
regardless of whether the exercise of any such remedy would result in any
penalty or loss of interest or profit with respect to any withdrawal of funds
deposited in a time deposit account prior to the maturity thereof. Furthermore,
the Borrower hereby grants to the Lender the right, exercisable at such time as
any Obligation shall mature, whether by acceleration of maturity or otherwise,
of offset or banker's lien against all funds of the Borrower now or hereafter or
from time to time on deposit with the Lender, regardless of whether the exercise
of any such remedy would result in any penalty or loss of interest or profit
with respect to any withdrawal of funds deposited in a time deposit account
prior to the maturity thereof.

            2.15 GENERAL PROVISIONS RELATING TO INTEREST. (a) It is the
intention of the parties hereto to comply strictly with the usury laws of the
State of Texas and the United States of America. In this connection, there shall
never be collected, charged, or received on the sums advanced hereunder interest
in excess of that which would accrue at the Highest Lawful Rate. For purposes of
Article 5069-1.04, Vernon's TEXAS CIVIL STATUTES, as amended, the Borrower
agrees that the Highest Lawful Rate shall be the "indicated (weekly) rate
ceiling" as defined in such Article, provided that the Lender may also rely, to
the extent permitted by applicable laws of the State of Texas or the United
States of America, on alternative maximum rates of interest under other laws of
the State of Texas or the United States of America applicable to the Lender, if
greater.

            (b) Notwithstanding anything herein or in the Note to the contrary,
during any Limitation Period, the interest rate to be charged on amounts
evidenced by the Note shall be the Highest Lawful Rate, and the obligation, if
any, of the Borrower for the payment of fees or other charges deemed to be
interest under applicable law shall be suspended. During any period or periods
of time following a Limitation Period, to the extent permitted by applicable
laws of the State of Texas or the United States of America, the interest rate to
be charged hereunder shall remain at the Highest Lawful Rate until such time as
there has been paid to the Lender (i) the amount of interest in excess of that
accruing at the Highest Lawful Rate that the Lender would have received during
the Limitation Period had the interest rate remained at the otherwise applicable
rate, and (ii) all interest and fees otherwise payable to the Lender but for the
effect of such Limitation Period.

            (c) If, under any circumstances, the aggregate amounts paid on the
Note or under this Agreement or any other Loan Document include amounts which by
law are deemed interest and which would

                                      21
<PAGE>
exceed the amount permitted if the Highest Lawful Rate were in effect, the
Borrower stipulates that such payment and collection will have been and will be
deemed to have been, to the extent permitted by applicable laws of the State of
Texas or the United States of America, the result of mathematical error on the
part of the Borrower and the Lender; and the Lender shall promptly refund the
amount of such excess (to the extent only of such interest payments in excess of
that which would have accrued and been payable on the basis of the Highest
Lawful Rate) upon discovery of such error by the Lender or notice thereof from
the Borrower. In the event that the maturity of any Obligation is accelerated,
by reason of an election by the Lender or otherwise, or in the event of any
required or permitted prepayment, then the consideration constituting interest
under applicable laws may never exceed the Highest Lawful Rate; and excess
amounts paid which by law are deemed interest, if any, shall be credited by the
Lender on the principal amount of the Obligations, or if the principal amount of
the Obligations shall have been paid in full, refunded to the Borrower.

            (d) All sums paid, or agreed to be paid, to the Lender for the use,
forbearance and detention of the proceeds of any advance hereunder shall, to the
extent permitted by applicable law, be amortized, prorated, allocated, and
spread throughout the full term hereof until paid in full so that the actual
rate of interest is uniform but does not exceed the Highest Lawful Rate
throughout the full term hereof.

            2.16 YIELD PROTECTION. (a) Without limiting the effect of the other
provisions of this Section (but without duplication), the Borrower shall pay to
the Lender from time to time such amounts as the Lender may determine are
necessary to compensate it for any Additional Costs incurred by the Lender.

            (b) Without limiting the effect of the other provisions of this
Section (but without duplication), the Borrower shall pay to the Lender such
amounts as shall be sufficient in the reasonable opinion of the Lender to
compensate it for any loss, cost, or expense incurred by and as a result of:

                  (i) any payment, prepayment, or conversion by the Borrower of
            a Fixed Rate Loan on a date other than the last day of an Interest
            Period for such Loan; or

                  (ii) any failure by the Borrower to borrow a Fixed Rate Loan
            from the Lender on the date for such borrowing specified in the
            relevant Borrowing Request;

                                       22
<PAGE>
such compensation to include, without limitation, with respect to any LIBO Rate
Loan, an amount equal to the excess, if any, of (A) the amount of interest which
would have accrued on the principal amount so paid, prepaid, converted, or not
borrowed for the period from the date of such payment, prepayment, conversion,
or failure to borrow to the last day of the then current Interest Period for
such Loan (or, in the case of a failure to borrow, the Interest Period for such
Loan which would have commenced on the date of such failure to borrow) at the
applicable rate of interest for such Loan provided for herein over (B) the
interest component (as reasonably determined by the Lender) of the amount (as
reasonably determined by the Lender) the Lender would have bid in the London
interbank market for Dollar deposits of amounts comparable to such principal
amount and maturities comparable to such period.

            (c) Determinations by the Lender for purposes of this Section of its
costs or rate of return, maintaining Loans, its obligation to make Loans, or on
amounts receivable by it in respect of Loans, or such obligations, and the
additional amounts required to compensate the Lender under this Section shall be
conclusive, absent manifest error, provided that such determinations are made on
a reasonable basis. The Lender shall furnish the Borrower with a certificate
setting forth in reasonable detail the basis and amount of increased costs
incurred or reduced amounts receivable as a result of any such event, and the
statements set forth therein shall be conclusive, absent manifest error. The
Lender shall (i) notify the Borrower, as promptly as practicable after the
Lender obtains knowledge of any Additional Costs or other sums payable pursuant
to this Section and determines to request compensation therefor, of any event
occurring after the Closing Date which will entitle the Lender to compensation
pursuant to this Section; provided that the Borrower shall not be obligated for
the payment of any Additional Costs or other sums payable pursuant to this
Section to the extent such Additional Costs or other sums accrued more than 90
days prior to the date upon which the Borrower was given such notice; and (ii)
designate a different Applicable Lending Office for the Loans of the Lender
affected by such event if such designation will avoid the need for or reduce the
amount of such compensation and will not, in the sole opinion of the Lender, be
disadvantageous to the Lender. If the Lender requests compensation from the
Borrower under this Section, the Borrower may, by notice to the Lender, require
that the Loans by the Lender of the type with respect to which such compensation
is requested be converted into Floating Rate Loans in accordance with Section .
Any compensation requested by the Lender pursuant to this Section shall be due
and payable to the Lender within five days of delivery of any such notice by the
Lender to the Borrower.

            (d) The Lender agrees that it shall not request, and the Borrower
shall not be obligated to pay, any Additional Costs or other sums payable
pursuant to this Section unless similar

                                      23
<PAGE>
additional costs and other sums payable are also generally assessed by the
Lender against other customers of the Lender similarly situated where such
customers are subject to documents providing for such assessment.

            2.17 LIMITATION ON TYPES OF LOANS. Anything herein to the contrary
notwithstanding, no more than six separate Loans shall be outstanding at any one
time, with, for purposes of this Section, all Floating Rate Loans constituting
one Loan, and all LIBO Rate Loans for the same Interest Period constituting one
Loan. Anything herein to the contrary notwithstanding, if, on or prior to the
determination of any interest rate for any LIBO Rate Loan for any Interest
Period therefor:

            (a) the Lender determines (which determination shall be conclusive)
      that quotations of interest rates for the deposits referred to in the
      definition of "LIBO Rate" in Section are not being provided in the
      relevant amounts or for the relevant maturities for purposes of
      determining the rate of interest for such Loan as provided in this
      Agreement; or

            (b) the Lender determines (which determination shall be conclusive)
      that the rates of interest referred to in the definition of "LIBO Rate" in
      Section upon the basis of which the rate of interest for such Loan for
      such Interest Period is to be determined do not accurately reflect the
      cost to the Lender of making or maintaining such Loan for such Interest
      Period,

then the Lender shall give the Borrower prompt notice thereof; and so long as
such condition remains in effect, the Lender shall be under no obligation to
make LIBO Rate Loans or to convert Loans of any other type into LIBO Rate Loans,
and the Borrower shall, on the last day of the then current Interest Period for
each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or convert
such Loan into another type of Loan in accordance with Section . Before giving
such notice pursuant to this Section, the Lender will designate a different
available Applicable Lending Office for LIBO Rate Loans or take such other
action as the Borrower may request if such designation or action will avoid the
need to suspend the obligation of the Lender to make LIBO Rate Loans hereunder
and will not, in the opinion of the Lender, be disadvantageous to the Lender.

            2.18 ILLEGALITY. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for the Lender or its
Applicable Lending Office to (a) honor its obligation to make any type of Fixed
Rate Loans hereunder, or (b) maintain any type of Fixed Rate Loans hereunder,
then the Lender shall promptly notify the Borrower thereof; and the obligation
of the Lender

                                      24
<PAGE>
hereunder to make such type of Fixed Rate Loans and to convert other types of
Loans into Fixed Rate Loans of such type shall be suspended until such time as
the Lender may again make and maintain Fixed Rate Loans of such type, and the
outstanding Fixed Rate Loans of such type shall be converted into Floating Rate
Loans in accordance with Section 2.9. Before giving such notice pursuant to this
Section, the Lender will designate a different available Applicable Lending
Office for Fixed Rate Loans or take such other action as the Borrower may
request if such designation or action will avoid the need to suspend the
obligation of the Lender to make Fixed Rate Loans and will not, in the opinion
of the Lender, be disadvantageous to the Lender.

            2.19 REGULATORY CHANGE. In the event that by reason of any
Regulatory Change, the Lender (a) 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 the Lender which includes deposits by reference to which
the interest rate on any Fixed Rate Loan is determined as provided in this
Agreement or a category of extensions of credit or other assets of such Lender
which includes any Fixed Rate Loan, or (b) becomes subject to restrictions on
the amount of such a category of liabilities or assets which it may hold, then,
at the election of the Lender with notice to the Borrower, the obligation of the
Lender to make such Fixed Rate Loans and to convert Floating Rate Loans into
such Fixed Rate Loans shall be suspended until such time as such Regulatory
Change ceases to be in effect, and all such outstanding Fixed Rate Loans shall
be converted into Floating Rate Loans in accordance with Section 2.9.

            2.20 LIMITATIONS ON INTEREST PERIODS. Each Interest Period selected
by the Borrower (a) which commences on the last Business Day of a calendar month
(or, with respect to any LIBO Rate Loan, any day for which there is no
numerically corresponding day in the appropriate subsequent calendar month)
shall end on the last Business Day of the appropriate subsequent calendar month,
(b) which would otherwise end on a day which is not a Business Day shall end on
the next succeeding Business Day (or, if such next succeeding Business Day falls
in the next succeeding calendar month, on the next preceding Business Day), (c)
which would otherwise commence before and end after Final Maturity shall end on
Final Maturity, and (d) shall have a duration of not less than one month, as to
any LIBO Rate Loan, and, if any Interest Period would otherwise be a shorter
period, the relevant Loan shall be a Floating Rate Loan during such period.

            2.21 LETTERS IN LIEU OF TRANSFER ORDERS. The Lender agrees that none
of the letters in lieu of transfer or division orders provided by the Borrower
pursuant to Section 3.1(g)(iii) or Section 5.8 will be sent to the addressees
thereof prior to the occurrence of an Event of Default, at which time the Lender
may, at

                                      25
<PAGE>
its option and in addition to the exercise of any of its other rights and
remedies, send any or all of such letters.

            2.22 POWER OF ATTORNEY. The Borrower hereby designates the Lender as
its agent and attorney-in-fact, to act in its name, place, and stead for the
purpose of completing and, upon the occurrence of an Event of Default,
delivering any and all of the letters in lieu of transfer orders delivered by
the Borrower to the Lender pursuant to Section 3.1(g)(iii) or Section 5.8,
including, without limitation, completing any blanks contained in such letters
and attaching exhibits thereto describing the relevant Collateral. The Borrower
hereby ratifies and confirms all that the Lender shall lawfully do or cause to
be done by virtue of this power of attorney and the rights granted with respect
to such power of attorney. This power of attorney is coupled with the interests
of the Lender in the Collateral, shall commence and be in full force and effect
as of the Closing Date and shall remain in full force and effect and shall be
irrevocable so long as any Obligation remains outstanding or unpaid or any
Commitment exists. The powers conferred on the Lender by this appointment are
solely to protect the interests of the Lender under the Loan Documents and shall
not impose any duty upon the Lender to exercise any such powers. The Lender
shall be accountable only for amounts that it actually receives as a result of
the exercise of such powers and shall not be responsible to the Borrower or any
other Person for any act or failure to act with respect to such powers, except
for gross negligence or willful misconduct.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

            To induce the Lender to enter into this Agreement and to make the
Loans, the Borrower represents and warrants to the Lender (which representations
and warranties shall survive the delivery of the Note) that:

            4.1 DUE AUTHORIZATION. The execution and delivery by the Borrower of
this Agreement and the borrowings hereunder, the execution and delivery by the
Borrower of the Note, the repayment of the Note and interest and fees provided
for in the Note and this Agreement, the execution and delivery of the Security
Instruments by the Borrower and the performance of all obligations of the
Borrower under the Loan Documents are within the power of the Borrower, have
been duly authorized by all necessary corporate action by the Borrower, and do
not and will not (a) require the consent of any Governmental Authority, (b)
contravene or conflict with any Requirement of Law, (c) contravene or conflict
with any indenture, instrument, or other agreement to which the Borrower is a
party or by which any Property of the Borrower may be presently

                                      30
<PAGE>
bound or encumbered, or (d) result in or require the creation or imposition of
any Lien in, upon or of any Property of the Borrower under any such indenture,
instrument, or other agreement, other than the Loan Documents.

            4.2 CORPORATE EXISTENCE. The Borrower is a corporation duly
organized, legally existing, and in good standing under the laws of its state of
incorporation and is duly qualified as a foreign corporation and is in good
standing in all jurisdictions wherein the ownership of Property or the operation
of its business necessitates same, other than those jurisdictions wherein the
failure to so qualify will not have a Material Adverse Effect.

            4.3 VALID AND BINDING OBLIGATIONS. All Loan Documents when duly
executed and delivered by the Borrower, will be the legal, valid, and binding
obligations of the Borrower, enforceable against the Borrower in accordance with
their respective terms.

            4.4 SECURITY INSTRUMENTS. The provisions of each Security Instrument
are effective to create in favor of the Lender, a legal, valid, and enforceable
Lien in all right, title, and interest of the Borrower in the Collateral
described therein, which Liens, assuming the accomplishment of recording and
filing in accordance with applicable laws prior to the intervention of rights of
other Persons, shall constitute fully perfected first-priority Liens on all
right, title, and interest of the Borrower in the Collateral described therein.

            4.5 TITLE TO ASSETS. The Borrower has good and indefeasible title to
all of its Properties, free and clear of all Liens except Permitted Liens.

            4.6 SCOPE AND ACCURACY OF PROFORMA BALANCE SHEET. The proforma
balance sheet of the Borrower as of April 30, 1996, present fairly the financial
position of the Borrower in accordance with GAAP as at the relevant point in
time or for the period indicated, as applicable. No event or circumstance has
occurred since April 30, 1996, which could reasonably be expected to have a
Material Adverse Effect.

            4.7 NO MATERIAL MISSTATEMENTS. No information, exhibit, statement,
or report furnished to the Lender by or at the direction of the Borrower in
connection with this Agreement contains any material misstatement of fact or
omits to state a material fact or any fact necessary to make the statements
contained therein not misleading as of the date made or deemed made.

            4.8 LIABILITIES, LITIGATION, AND RESTRICTIONS. Other than as listed
under the heading "Liabilities" on Exhibit attached hereto, the Borrower has no
liabilities, direct, or contingent, which may materially and adversely affect
its business

                                      31
<PAGE>
or operations or its ownership of the Collateral. Except as set forth under the
heading "Litigation" on Exhibit hereto, no litigation or other action of any
nature affecting the Borrower is pending before any Governmental Authority or,
to the best knowledge of the Borrower, threatened against or affecting the
Borrower which might reasonably be expected to result in any impairment of its
ownership of any Collateral or have a Material Adverse Effect. To the best
knowledge of the Borrower, after due inquiry, no unusual or unduly burdensome
restriction, restraint or hazard exists by contract, Requirement of Law, or
otherwise relative to the business or operations of the Borrower or the
ownership and operation of the Collateral other than such as relate generally to
Persons engaged in business activities similar to those conducted by the
Borrower.

            4.9 AUTHORIZATIONS; CONSENTS. Except as expressly contemplated by
this Agreement, no authorization, consent, approval, exemption, franchise,
permit, or license of, or filing with, any Governmental Authority or any other
Person is required to authorize or is otherwise required in connection with the
valid execution and delivery by the Borrower of the Loan Documents or any
instrument contemplated hereby, the repayment by the Borrower of the Note and
interest and fees provided in the Note and this Agreement, or the performance by
the Borrower of the Obligations.

            4.10 COMPLIANCE WITH LAWS. The Borrower and its Property, including,
without limitation, the Mortgaged Property, are in compliance with all
applicable Requirements of Law, including, without limitation, Environmental
Laws, the Natural Gas Policy Act of 1978, as amended, and ERISA, except to the
extent non-compliance with any such Requirements of Law could not reasonably be
expected to have a Material Adverse Effect.

            4.11 ERISA. No Reportable Event has occurred with respect to any
Single Employer Plan, and each Single Employer Plan has complied with and been
administered in all material respects in accordance with applicable provisions
of ERISA and the Code. To the best knowledge of the Borrower, (a) no Reportable
Event has occurred with respect to any Multiemployer Plan, and (b) each
Multiemployer Plan has complied with and been administered in all material
respects with applicable provisions of ERISA and the Code. The present value of
all benefits vested under each Single Employer Plan maintained by the Borrower
or any Commonly Controlled Entity (based on the assumptions used to fund such
Plan) did not, as of the last annual valuation date applicable thereto, exceed
the value of the assets of such Plan allocable to such vested benefits. Neither
the Borrower nor any Commonly Controlled Entity has had a complete or partial
withdrawal from any Multiemployer Plan for which there is any withdrawal
liability. As of the most recent valuation date applicable to any Multiemployer
Plan, neither the Borrower nor any Commonly Controlled Entity would become
subject to any liability under ERISA if the Borrower or such Commonly

                                      32
<PAGE>
Controlled Entity were to withdraw completely from such Multiemployer Plan.
Neither the Borrower nor any Commonly Controlled Entity has received notice that
any Multiemployer Plan is Insolvent or in Reorganization. To the best knowledge
of the Borrower, no such Insolvency or Reorganization is reasonably likely to
occur. Based upon GAAP existing as of the date of this Agreement and current
factual circumstances, the Borrower has no reason to believe that the annual
cost during the term of this Agreement to the Borrower and all Commonly
Controlled Entities for post-retirement benefits to be provided to the current
and former employees of the Borrower and all Commonly Controlled Entities under
Plans which are welfare benefit plans (as defined in Section 3(1) of ERISA)
will, in the aggregate, have a Material Adverse Effect.

            4.12 ENVIRONMENTAL LAWS. To the best knowledge and belief of the
Borrower, except as would not have a Material Adverse Effect, or as described on
Exhibit V under the heading "Environmental Matters:"

            8.4 PARTIES IN INTEREST. Subject to the restrictions on changes in
corporate structure set forth in Section and other applicable restrictions
contained herein, all covenants and agreements herein contained by or on behalf
of the Borrower or the Lender shall be binding upon and inure to the benefit of
the Borrower or the Lender, as the case may be, and their respective legal
representatives, successors, and assigns.

            8.5 RIGHTS OF THIRD PARTIES. All provisions herein are imposed
solely and exclusively for the benefit of the Lender and the Borrower. No other
Person shall have any right, benefit, priority, or interest hereunder or as a
result hereof or have standing to require satisfaction of provisions hereof in
accordance with their terms, and any or all of such provisions may be freely
waived in whole or in part by the Lender at any time if in its sole discretion
it deems it advisable to do so.

            8.6 RENEWALS; EXTENSIONS. All provisions of this Agreement relating
to the Note shall apply with equal force and effect to each promissory note
hereafter executed which in whole or in part represents a renewal or extension

<PAGE>
failure or delay by the Lender with respect to exercising any of its rights
under any Loan Document shall operate as a waiver thereof. The rights of the
Lender under the Loan Documents shall be cumulative and the exercise or partial
exercise of any such right shall not preclude the exercise of any other right.
The making of any Loan shall not constitute a waiver of any of the covenants,
warranties, or conditions of the Borrower contained herein. In the event the
Borrower is unable to satisfy any such covenant, warranty, or condition, the
making of any Loan shall not have the effect of precluding the Lender from
thereafter declaring such inability to be an Event of Default as hereinabove
provided.

            8.8 SURVIVAL UPON UNENFORCEABILITY. In the event any one or more of
the provisions contained in any of the Loan Documents or in any other instrument

invalidity, illegality, or unenforceability shall not affect any other provision
of any Loan Document or of any other instrument referred to herein or executed
in connection with such Obligations.

            8.9 AMENDMENTS; WAIVERS. Neither this Agreement nor any provision
hereof may be amended, waived, discharged, or terminated orally, but only by an
instrument in writing signed by the party against whom enforcement of the
amendment, waiver, discharge, or termination is sought.

            8.10 CONTROLLING AGREEMENT. In the event of a conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control.

            8.11 DISPOSITION OF COLLATERAL. Notwithstanding any term or
provision, express or implied, in any of the Security Instruments, the
realization, liquidation, foreclosure, or any other disposition on or of any or
all of the Collateral shall be in the order and manner and determined in the
sole discretion of the Lender; provided, however, that in no event shall the
Lender violate applicable law or exercise rights and remedies other than those
provided in such Security Instruments or otherwise existing at law or in equity.

            8.12 GOVERNING LAW. THIS AGREEMENT AND THE NOTE SHALL BE DEEMED TO
BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF

                                 [Closing Date]

Attention:  Energy Lending Group

      Re:   Credit Agreement dated as of June 7, 1996, by and between Compass
            Bank-Houston and Tenneco Ventures Finance Corporation (as amended,
            restated, or supplemented from time to time, the "CREDIT AGREEMENT")

Ladies and Gentlemen:

            We have acted as counsel to Tenneco Ventures Finance Corporation
(the "BORROWER") in connection with the transactions contemplated in the Credit
Agreement. This Opinion is delivered pursuant to Section of the Credit
Agreement, and the Lender is hereby authorized to rely upon this Opinion in
connection with the transactions contemplated in the Credit Agreement. Each
capitalized term used but not defined herein shall have the meaning assigned to
such term in the Credit Agreement.

            In our representation of the Borrower, we have examined an executed
counterpart of each of the following (the "LOAN DOCUMENTS"):

            (a)   the Credit Agreement;

            (b)   the Note;

            (c) Mortgage, Deed of Trust, Indenture, Security Agreement,
      Assignment of Production, and Financing Statement dated of even date
      herewith from the Borrower in favor of the Lender (the "MORTGAGE"); and

            (d) Financing Statements from the Borrower, as debtor, constituent
      to the Mortgage (the "FINANCING STATEMENT").

            We have also examined the originals, or copies certified to our
satisfaction, of such other records of the Borrower, certificates of public
officials and officers of the Borrower

                                       IV-i
<PAGE>
agreements, instruments, and documents as we have deemed necessary as a basis
for the opinions hereinafter expressed.

            In making such examinations, we have, with your permission, assumed:

            (a) the genuineness of all signatures to the Loan Documents other
      than those of the Borrower;

            (b) the authenticity of all documents submitted to us as originals
      and the conformity with the originals of all documents submitted to us as
      copies;

            (c) the Lender is authorized and has the power to enter into and
      perform its obligations under the Credit Agreement;

            (d) the due authorization, execution, and delivery of all Loan
      Documents by each party thereto other than the Borrower; and

            (e) the Borrower has title to all Property covered or affected by
      the Mortgage.

            Based upon the foregoing and subject to the qualifications set forth
herein, we are of the opinion that:

            1. The Borrower is a corporation duly organized, legally existing,
      and in good standing under the laws of its state of incorporation and is
      duly qualified as a foreign corporation and is in good standing in all
      jurisdictions wherein the ownership of its Property or the operation of
      its business necessitates same.

            2. The execution and delivery by the Borrower of the Credit
      Agreement and the borrowings thereunder, the execution and delivery by the
      Borrower of the other Loan Documents to which the Borrower is a party, and
      the payment and performance of all Obligations of the Borrower thereunder
      are within the power of the Borrower, have been duly authorized by all
      necessary corporate action, and do not (a) require the consent of any
      Governmental Authority, (b) contravene or conflict with any Requirement of
      Law, (c) to our knowledge after due inquiry, contravene or conflict with
      any indenture, instrument, or other agreement to which the Borrower is a
      party or by which any Property of the Borrower may be presently bound or
      encumbered, or (d) result in or require the creation or imposition of any
      Lien upon any Property of the Borrower other than as contemplated by the
      Loan Documents.

                                       IV-ii
<PAGE>
            3. The Loan Documents to which the Borrower is a party constitute
      legal, valid, and binding obligations of the Borrower, enforceable against
      the Borrower in accordance with their respective terms.

            4. The forms of the Mortgage and the Financing Statement and the
      description of the Mortgaged Property (as such term is defined in the
      Mortgage and so used herein) situated in the State of Texas (the "STATE")
      satisfy all applicable Requirements of Law of the State and are legally
      sufficient under the laws of the State to enable the Lender to realize the
      practical benefits purported to be afforded by the Mortgage.

            5. The Mortgage creates a valid lien upon and security interest in
      all Mortgaged Property situated in the State to secure the Indebtedness
      (as such term is defined in the Mortgage and so used herein).

            6. The Mortgage and the Financing Statement are in satisfactory form
      for filing and recording in the offices described below.

            7. The filing and/or recording, as the case may be, of (a) the
      Mortgage in the office of the county clerk of each county in the State in
      which any portion of the Mortgaged Property is located, and as a financing
      statement and utility security instrument in the office of the Secretary
      of State of the State, and (b) the Financing Statement in the Uniform
      Commercial Code records in each county in the State in which any portion
      of the Mortgaged Property is located are the only recordings or filings in
      the State necessary to perfect the liens and security interests in the
      Mortgaged Property created by the Mortgage or to permit the Lender to
      enforce in the State its rights under the Mortgage. No subsequent filing,
      re-filing, recording, or rerecording will be required in the State in
      order to continue the perfection of the liens and security interests
      created by the Mortgage except that (a) a continuation statement must be
      filed with respect to the Mortgage filed as a financing statement in the
      office of the Secretary of State of the State and with respect to the
      Financing Statement in the Uniform Commercial Code records in each county
      in the State in which any portion of the Mortgaged Property is located,
      each within six months prior to the expiration of five years from the date
      of the relevant initial financing statement filing, (b) a subsequent
      continuation statement must be filed within six months prior to the
      expiration of each subsequent five-year period from the date of each
      initial
                                      IV-iii
<PAGE>
      financing statement filing, and (c) amendments or supplements to the
      Mortgage filed as a financing statement and the Financing Statement and/or
      additional financing statements may be required to be filed in the event
      of a change in the name, identity, or structure of the Borrower or in the
      event the financing statement filing otherwise becomes inaccurate or
      incomplete.

            8. To our knowledge after due inquiry, except as disclosed in
      Exhibit to the Credit Agreement, no litigation or other action of any
      nature affecting the Borrower is pending before any Governmental Authority
      or threatened against the Borrower. To our knowledge after due inquiry, no
      unusual or unduly burdensome restriction, restraint, or hazard exists by
      contract, Requirement of Law, or otherwise relative to the business or
      operations of the Borrower or the ownership and operation of any
      Properties of the Borrower other than such as relate generally to Persons
      engaged in business activities similar to those conducted by the Borrower.

            9. No authorization, consent, approval, exemption, franchise, permit
      or license of, or filing (other than filing of Security Instruments in
      appropriate filing offices) with, any Governmental Authority or any other
      Person is required to authorize or is otherwise required in connection
      with the valid execution and delivery by the Borrower of the Loan
      Documents or any instrument contemplated thereby, or the payment
      performance by the Borrower of the Obligations.

            10. No transaction contemplated by the Loan Documents is in
      violation of any regulations promulgated by the Board of Governors of the
      Federal Reserve System, including, without limitation, Regulations G, T,
      U, or X.

            11. The Borrower is not, nor is the Borrower directly or indirectly
      controlled by or acting on behalf of any Person which is, an "investment
      company" or an "affiliated person" of an "investment company" within the
      meaning of the Investment Company Act of 1940, as amended.

            12. The Borrower is not a "holding company," or an "affiliate" of a
      "holding company" or of a "subsidiary company" of a "holding company,"
      within the meaning of the Public Utility Holding Company Act of 1935, as
      amended.

      The opinions expressed herein are subject to the following qualifications
and limitations: 

                                     IV-iv
<PAGE>
            A. We are licensed to practice law only in the State and other
      jurisdictions whose laws are not applicable to the opinions expressed
      herein; accordingly, the foregoing opinions are limited solely to the laws
      of the State, applicable United States federal law, and the corporation
      laws of the State of [_______________].

            B. The validity, binding effect, and enforce-ability of the Loan
      Documents may be limited or affected by bankruptcy, insolvency,
      moratorium, reorganization, or other similar laws affecting rights of
      creditors generally, including, without limitation, statutes or rules of
      law which limit the effect of waivers of rights by a debtor or grantor;
      provided, however, that the limitations and other effects of such statutes
      or rules of law upon the validity and binding effect of the Loan Documents
      should not differ materially from the limitations and other effects of
      such statutes or rules of law upon the validity and binding effect of
      credit agreements, promissory notes, and security instruments generally.

            C. The enforceability of the respective obligations of the Borrower
      under the Loan Documents is subject to general principles of equity
      (whether such enforceability is considered in a suit in equity or at law).

            This Opinion is furnished by us solely for the benefit of the Lender
in connection with the transactions contemplated by the Loan Documents and is
not to be quoted in whole or in part or otherwise referred to or disclosed in
any other transaction.

                                    Very truly yours,

               (h)  TITLE TO PROPERTIES; ENCUMBRANCES.

                           (i) The Company, the Tenneco Entities and the Tenneco
               Entities' Subsidiaries have good and marketable title to the
               respective real properties and oil and gas reserves that they own
               and which are reflected on the Balance Sheet and other 1995
               financial statements referred to in Section 5.1(f) or were
               acquired since December 31, 1995, including all joint ventures
               and other investments (collectively, the "FEE PROPERTIES") free
               and clear of all Liens except (a) capitalized financing leases,
               (b) Liens for ad valorem real property taxes not yet due or
               payable, due but not yet payable or due and payable but not yet
               delinquent, (c) mechanics', materialmen's, operators, tax or
               similar Liens affecting the Fee Properties (but not excepting any
               such Liens which secure obligations which are delinquent unless
               such delinquent obligations are being contested in good faith by
               appropriate legal proceedings), (d) purchase money Liens arising
               in the ordinary course of business which may be delinquent
               PROVIDED, such delinquent Liens are being contested in good faith
               by appropriate legal proceedings, (e) those mortgages, pledges
               and other Liens identified on SCHEDULE 5.1(H)(I), (f) the
               mortgages, security interests and Liens granted pursuant to the
               Credit Agreement or any documents executed in connection
               therewith and (g) such imperfections of title, easements and
               other similar encumbrances, if any, which do not in the aggregate
               materially detract from the value or materially interfere with
               the present use by the Company, the Tenneco Entities and the
               Tenneco Entities' Subsidiaries, as the case may be, of the Fee
               Properties. Fee Properties consisting of oil and gas reserves are
               sometimes hereinafter referred to as "FEE RESERVES."

                          (ii) The Company has made available to the Buyer all
               agreements (collectively, with any and all amendments,
               supplements or other modifications thereto, the "OIL AND GAS
               LEASES") pursuant to which the Company, the Tenneco Entities and
               the Tenneco Entities' Subsidiaries lease, sublease or otherwise
               possess any occupancy, usage rights or Oil and Gas Interests with
               respect to any real property (such properties are hereinafter
               referred to collectively as the "LEASED PROPERTIES"; the Leased
               Properties together with the Fee Properties, collectively, the
               "PROPERTIES") or the reserves of oil and gas described on the
               1995 financial statements referred to in Section 5.1(f) (the
               "LEASED RESERVES"). The Leased Reserves together with the Fee
<PAGE>
               Reserves are hereinafter collectively referred to as the
               "RESERVES". Except with respect to the Reserves, the Company, the
               Tenneco Entities and the Tenneco Entities' Subsidiaries have no
               reserves of oil and gas and the Reserves are all of the oil and
               gas reserves utilized by the Company, the Tenneco Entities and
               the Tenneco Entities' Subsidiaries in its business.

                         (iii) The Tenneco Entities or one of the Tenneco
               Entities' Subsidiaries is a party to each of the Oil and Gas
               Leases pursuant to which the Tenneco Entities or one of the
               Tenneco Entities' Subsidiaries leases the Leased Properties and
               the Leased Reserves. Each of the Oil and Gas Leases is validly
               executed by the lessee, in full force and effect and represents a
               binding obligation of the Tenneco Entities, the Tenneco Entities'
               Subsidiary (as the case may be) and, to the Knowledge of the
               Company, the lessor thereunder in accordance with the terms
               thereof. Except as set forth in SCHEDULE 5.1(H)(I), there is no
               default by the Tenneco Entities or any of the Tenneco Entities'
               Subsidiaries under the Oil and Gas Leases or to the Knowledge of
               the Company by any of the other parties to the Oil and Gas
               Leases, nor, to the Knowledge of the Company, has any event
               occurred which with notice, the passage of time or both would
               constitute such a default. The Company has no Knowledge of any
               adverse claims to the Leased Reserves or the rights described in
               the Oil and Gas Leases, nor have the Tenneco Entities received
               any notice of default under the Oil and Gas Leases and the quiet
               and peaceful possession of the Leased Reserves by the Tenneco
               Entities or one of the Tenneco Entities' Subsidiaries has not
               been disturbed. Except as disclosed on SCHEDULE 5.1(H)(I), the
               Tenneco Entities have no Knowledge of any facts which, through
               notice or the passage or time, would constitute grounds for a
               forfeiture of any of the Leased Reserves under any of the Oil and
               Gas Leases. Except as otherwise may be set forth in any of the
               Oil and Gas Leases, to the Knowledge of the Company, each of the
               lessors or sub-lessors under the Oil and Gas Leases has title to
               the Leased Reserves leased pursuant thereto. For purposes hereof,
               the term "title" shall mean that the party possessing the same
               has good and marketable title to all oil and gas to which such
               expression is directed, together with all rights necessary to
               remove such oil and gas, the necessary rights to conduct such
               removal and the right to lease or sublease same to the Tenneco
               Entities and the Tenneco Entities' Subsidiaries in accordance
               with the terms of the Oil and Gas Leases.

                          (iv)      Except as set forth in SCHEDULE 5.1(H)(IV),
               to the Knowledge of the Company, (i) the operations of
<PAGE>
               the Tenneco Entities and the Tenneco Entities' Subsidiaries are
               not dependent upon any rights to the use of real properties of
               others except under the Oil and Gas Leases, the Licenses and the
               Contracts and (ii) all buildings, structures, machines and
               equipment used in the operations of the Tenneco Entities and the
               Tenneco Entities' Subsidiaries have been maintained in all
               respects in a state of adequate repair and are otherwise
               generally adequate for their normal operation, except for such
               failures that, individually or in the aggregate, would not have a
               Material Adverse Effect. Except as set forth in SCHEDULE
               5.1(H)(IV), (A) the Tenneco Entities have not received any notice
               that (1) any of such buildings, structures, machines, equipment
               or (2) the current use of the Properties does not conform in all
               material respects with all applicable ordinances, regulations and
               zoning or other laws, (B) such machinery and equipment is in all
               material respects in useable condition, and (C) to the Knowledge
               of the Company, there is no pending or threatened condemnation,
               eminent domain or similar proceeding affecting any part of the
               Properties or the Reserves.

                           (v) Other than in the ordinary course of business,
               neither the Tenneco Entities nor any of the Tenneco Entities'
               Subsidiaries have leased, subleased, optioned, assigned or
               otherwise transferred or entered into any agreement to lease,
               sublease, option, assign or otherwise transfer any interest in
               the Reserves so as to materially reduce its interest in the
               Reserves as reflected in the financial statements referred to in
               Section 5.1(f). No rights of reassignment, preferential purchase
               rights, option rights, back-in rights or other rights to transfer
               any material interest in any of the Reserves to any third party
               exist that would be triggered or violated by this Agreement.

                          (vi) To the Knowledge of the Company, the Tenneco
               Entities and the Tenneco Entities' Subsidiaries own or control
               all material ancillary rights, including surface access rights,
               rights-of-way, water rights, access to utilities and the like
               necessary to gain vehicular and pedestrian access to, produce,
               process and market Reserves from the Properties in the same
               manner and at the same rates as were in effect as of December 31,
               1995.

                         (vii) With respect to the Fee Reserves, there are no
               parties in possession or, to the Knowledge of the Company,
               asserting a right of possession adverse to the possession of the
               Tenneco Entities or the Tenneco Entities' Subsidiaries, and, to
               the Knowledge of the
<PAGE>
               Tenneco Entities, there are no parties asserting title adverse to
               the title of the Tenneco Entities or any of the Tenneco Entities'
               Subsidiaries which, if successful, would materially detract from
               the value or materially interfere with the present use by the
               Tenneco Entities and the Tenneco Entities' Subsidiaries of the
               Fee Reserves and the Fee Properties.

               (i) ABSENCE OF LIENS. Except as described in SCHEDULE 5.1(I),
        each of the Tenneco Entities and the Tenneco Entities' Subsidiaries has
        good title, free of all Liens, to all equipment, machinery and fixtures
        (to the extent they constitute personal property) owned or utilized in
        its business (or a valid and binding lease therefor) and all its
        receivables (the "PERSONAL PROPERTIES") except for (A) capitalized
        financing leases, (B) Liens for ad valorem personal property taxes not
        yet due or payable, due but not yet payable, or due and payable but not
        yet delinquent, (C) landlords' or similar Liens affecting the Personal
        Properties, (D) purchase money Liens arising in the ordinary course of
        business, (E) the mortgages, security interests and Liens granted
        pursuant to the Credit Agreement or any documents executed in connection
        therewith, (F) Liens permitted under the Credit Agreement and (G) Liens
        which do not, individually or in the aggregate, materially detract from
        the value of the Personal Properties or materially interfere with the
        present uses thereof.

               (j) INSURANCE AND BONDS. All policies of insurance,
        self-insurance permits (other than insurance provided to employees) and
        reclamation, workers compensation and other bonds relating to the
        Tenneco Entities and the Tenneco Entities' Subsidiaries and their
        respective businesses, assets and employees as of the date hereof

        Tenneco Entities' Subsidiaries are insured in such amounts and against
        such risks as are usually insured against by Persons owning or operating
        similar properties in the localities where such properties are located.

               (k) CONTRACTS. Except for the Transaction Documents, the Oil and
        Gas Leases, the insurance policies and bonds referred to in Section

                           (i) Each "employee benefit plan", as defined in
               Section 3(3) of the Employee Retirement Income Security Act of
               1974, as amended ("ERISA") (including each multiemployer plan
               within the meaning of 3(37) of ERISA), each bonus, fringe
               benefit, incentive, stock option, deferred compensation,
               employment, consulting, severance and all other employee benefit
               plans, programs, policies, agreements and arrangements,
<PAGE>
               whether or not covered by ERISA under which the Company, the
               Tenneco Entities or any of the Tenneco Entities' Subsidiaries has
               or could have any present or future material obligation or
               liability (collectively, the "BENEFIT PLANS") are listed in
               SCHEDULE 5.1(O). The Company or the Tenneco Entities have
               delivered to the Buyer, to the extent requested by the Buyer,
               current, correct and complete copies of each Benefit Plan and any
               related agreements or funding instruments (or, to the extent no
               such copy exists, a current, correct and complete description
               thereof) and, to the extent applicable, (A) the most recent
               summary plan description and Internal Revenue Service
               determination letter, if any, relating to each Benefit Plan and
               (B) for the two most recent plan years (I) the form 5500 and
               attached schedules; (II) audited financial statements; (III)
               actuarial valuation reports; and (IV) attorney's response to an
               auditor's request for information.

                          (ii) No Benefit Plan is a "multiemployer plan" as such
               term is defined in Section 4001(a)(3) of ERISA ("MULTIEMPLOYER
               PLAN"). Neither the Company, the Tenneco Entities, nor any of the
               Tenneco Entities' Subsidiaries nor any trade or business, whether
               or not incorporated, which is under common control with the
               Company or the Tenneco Entities within the meaning of Code
               Section 414(b), (c), (m) or (o) or ERISA Section 4001 (excluding
               El Paso and its subsidiaries other than the Tenneco Entities and
               the Tenneco Entities Subsidiaries') (collectively, the
               "CONTROLLED GROUP") have incurred any liability in connection
               with a complete or partial withdrawal from a Multiemployer Plan.
               To the Knowledge of the Company and the Tenneco Entities, no such
               Multiemployer Plan is in "reorganization" or is "insolvent"(as
               those terms are defined in Section 4241 and Section 4245 of
               ERISA, respectively).

                         (iii) Each Benefit Plan, which is intended to be
               "qualified" within the meaning of Section 401(a) of the Internal
               Revenue Code of 1986, as amended (the "CODE") (a "PENSION PLAN"),
               is so qualified and has received a favorable determination letter
               as to its qualification, and nothing has occurred which would
               cause the loss of such qualification, in each case except for
               such circumstances that, individually or in the aggregate, would
               not have a Material Adverse Effect.

                          (iv) Each Benefit Plan is intended by the Company and
               the Tenneco Entities to have been, and to the Knowledge of the
               Company has been, established, maintained and administered in all
               material respects in accordance with its terms and the
               requirements of
<PAGE>
               applicable law, including without limitation ERISA and the Code.
               There are not now, nor have there been, any "accumulated funding
               deficiencies" as defined in Section 412 of the Code (whether or
               not waived) with respect to any Benefit Plan which have not been
               fully satisfied. No "reportable event" (as that term is defined
               in Section 4043(b) of ERISA) has occurred with respect to any
               Benefit Plan.

                           (v) No Pension Plan maintained by a member of the
               Controlled Group which is subject to Title IV of ERISA has been
               terminated, in whole or in part, and no proceedings to terminate
               a Benefit Plan pursuant to Subtitle C of Title IV of ERISA have
               been instituted or, to the Knowledge of the Company, threatened.
               As of the date of this Agreement, there are no pending or
               threatened claims, actions, suits, complaints or proceedings by
               or before any court, Governmental Authority, administrative
               agency or commission alleging a breach or breaches of fiduciary
               duties or violation of other applicable laws with respect to such
               Benefit Plans, or otherwise involving the Benefit Plans, which
               could result in material liability on the part of the Company,
               the Tenneco Entities, any of the Tenneco Entities' Subsidiaries
               or on a Benefit Plan or a Pension Plan maintained by a member of
               the Controlled Group (other than benefit claims in the ordinary
               course), nor, to the Knowledge of the Company, is there any basis
               for any such claims, actions, suits, complaints or proceedings.

                          (vi) There has been no material adverse change in the
               funded status of any Benefit Plan that is subject to Title IV of
               ERISA since the most recent valuation date.

                         (vii) No Benefit Plan exists which could result in the
               payment by the Company, the Tenneco Entities, any of the Tenneco
               Entities' Subsidiaries, any member of its Controlled Group or the
               Buyer of money or any other property or rights, or accelerate or
               provide any other rights or benefits, to any person as a result
               of the Transactions, including without limitation the sale of
               Company Shares hereunder, whether or not such payment would
               constitute a parachute payment within the meaning of Section 280G
               of the Code, other than as expressly provided for in the
               Transaction Documents.

                        (viii) The maximum liability under the obligations being
               assumed by the Company under Section 9.04 of the Stock Purchase
               Agreement does not exceed $1,400,000.

               (p)  LICENSES AND GOVERNMENT APPROVALS.  Except as set
        forth on SCHEDULE 5.1(P), the Company does not have
<PAGE>
        Knowledge of any impediment to the renewal of any license, permit,
        approval, consent, franchise and other authorization of any federal,
        state, local or foreign Governmental Authority (collectively,
        "LICENSES") possessed by or granted to the Company, the Tenneco Entities
        or the Tenneco Entities' Subsidiaries and material to their respective
        businesses as currently and during the past year have been conducted. To
        the Knowledge of the Company, all such Licenses are valid and in full
        force and effect and no proceeding is pending or, to the Knowledge of
        the Company, threatened seeking the suspension, modification, revocation
        or limitation of any such License. The Company, the Tenneco Entities and
        the Tenneco Entities' Subsidiaries have all the necessary Licenses that
        are required to permit the continued operation after the date hereof of
        the businesses of the Company, the Tenneco Entities and the Tenneco
        Entities' Subsidiaries as they are now being and during the past year
        have been conducted, with the exception of any change or changes in the
        operation of such businesses as would not, individually or in the
        aggregate, have a Material Adverse Effect. The Company, the Tenneco
        Entities and the Tenneco Entities' Subsidiaries reasonably believe that,
        other than for such exceptions that would not, individually or in the
        aggregate, have a Material Adverse Effect: each of their Licenses will
        be timely renewed and complied with, without material expense; and that
        any additional Licenses that may be required of any of them to permit
        any of their operations as planned will be timely obtained and complied
        with, without material expense. Except as disclosed on SCHEDULE 5.1(P)
        and except for the expiration or termination of all applicable waiting
        periods under the HSR Act, the execution, delivery and performance of
        this Agreement and the other Transaction Documents and the consummation
        by the Company and the Tenneco Entities of the transactions contemplated
        hereby and thereby (including without limitation the sale of the Company
        Shares contemplated hereby and the borrowings contemplated by the Credit
        Agreement) will not require the consent, approval or authorization of
        any Governmental or regulatory Authority or any other Person under any
        License, agreement, indenture or other instrument to which the Company,
        the Tenneco Entities or any of the Tenneco Entities' Subsidiaries is a
        party or to which any of their respective properties are subject that
        have not already been obtained, and no declaration, filing or
        registration with any Governmental or regulatory Authority is required
        in connection with such transactions.

               (q) BROKER'S OR FINDER'S FEES. Except for PaineWebber
        Incorporated, neither the Company or the Tenneco Entities nor any
        Affiliate or agent of either of them have authorized any Person to act
        as a broker or finder or in any similar capacity in connection with the
        transactions contemplated by this Agreement. The Company has previously
        delivered to the Buyer a true, correct and complete copy of all
        agreements,
<PAGE>
        arrangements and undertakings between the Company and
        PaineWebber Incorporated.

               (r) TRANSACTIONS WITH AFFILIATES. Except as disclosed in SCHEDULE
        5.1(R), neither the Company, the Tenneco Entities nor any of the Tenneco
        Entities' Subsidiaries has any outstanding contract, agreement or other
        arrangement with the Company, the Tenneco Entities, or any of the
        Affiliates of the Company or the Tenneco Entities (other than those to
        which the only parties are the Company, the Tenneco Entities and/or the
        Tenneco Entities' Subsidiaries). Except as disclosed in Schedule 5.1(r),
        neither El Paso nor any of its Affiliates has issued any performance
        bonds, payment bonds, bid bonds, letters of credit, guaranties or
        similar instruments for the benefit of the Company, the Tenneco
        Entities, the Tenneco Entities' Subsidiaries nor the Investments.

               (s) CORPORATE RECORDS. The books and records of the Company, the
        Tenneco Entities and the Tenneco Entities' Subsidiaries are complete and
        correct in all material respects and have been maintained in accordance
        with good business practices.

               (t) LABOR MATTERS. Except as set forth in SCHEDULE 5.1(T),
        neither the Company, the Tenneco Entities, any of the Tenneco Entities'
        Subsidiaries nor any member of the Controlled Group is subject to or a
        party to any collective bargaining agreement, employment contract or
        consulting agreement and no collective bargaining agreement, employment
        agreement or consulting agreement is being negotiated. Except as
        disclosed in SCHEDULE 5.1(T), there are no strikes, slowdowns, work
        stoppages or other material labor controversies pending or, to the
        Knowledge of the Company, threatened against or otherwise affecting the
        Company, the Tenneco Entities or the Tenneco Entities' Subsidiaries.
        Neither the Company, the Tenneco Entities nor any of the Tenneco
        Entities' Subsidiaries has experienced any labor strike, slowdown, work
        stoppage or other material labor controversy within the past three
        years. Other than certain severance payments and retention bonuses due
        to certain employees of the Company which will be paid in due course,
        the Company, the Tenneco Entities and the Tenneco Entities' Subsidiaries
        have paid in full to all their respective employees all wages, salaries,
        commissions, bonuses, benefits and other compensation due to such
        employees or otherwise arising under any policy, agreement, program,
        statute or other law. Neither the Company, the Tenneco Entities nor any
        of the Tenneco Entities' Subsidiaries is a party to, or otherwise bound
        by, any consent decree with, or citation by, any court or Governmental
        Authority relating to employees or employment practices. To the
        Knowledge of the Company, during the past three years none of the
        Company, the Tenneco Entities or any
<PAGE>
        of the Tenneco Entities' Subsidiaries has received any petition from any
        employees to form, join, or assist labor organizations to bargain
        collectively through representatives of the employees' choosing or has
        received information about employees engaging in other concerted
        activities for the purpose of collective bargaining.

               (u)  TAX MATTERS.  Except as set forth in the last
        sentence of this Section 4.1(u) and in SCHEDULE 5.1(U):

                           (i) All Tax Returns (as hereinafter defined) required
               by law to be filed (and/or maintained) on or prior to the date
               hereof by, or with respect to the operations, activities or
               assets of the Company, the Tenneco Entities or any of the Tenneco
               Entities' Subsidiaries (other than any consolidated, combined or
               unitary income or franchise tax returns filed by either Tenneco,
               Inc. or El Paso (as common parent) on behalf of any of the
               Tenneco Entities or the Tenneco Entities' Subsidiaries) have been
               properly and timely filed with the appropriate governmental
               agencies (and/or maintained, as the case may be), and all such
               Tax Returns are correct, accurate and complete in all material
               respects. All Taxes (as hereinafter defined) shown as due on such
               Tax Returns have been paid. For purposes of this Agreement, "TAX"
               or "TAXES" will mean any and all federal, state, local, foreign
               and other taxes and tax withholding obligations (including
               interest, additions to tax, penalties and fines with respect
               thereto) including, without limitation, taxes imposed on, or
               measured by, income, franchise, profits, or gross receipts, and
               also ad valorem, value added, sales, use, service, real or
               personal property, capital stock, license, payroll, withholding,
               employment, social security, workers' compensation, unemployment
               compensation, utility, severance, production, excise, stamp,
               occupation, premium, windfall profits, transaction, and joint
               taxes, and customs duties. "TAX RETURN" or "TAX RETURNS" will
               mean any report, return or other information, or any amendment
               thereof, filed or required to be filed, maintained or supplied in
               connection with the calculation, determination, assessment,
               collection or remittance of any Tax.

                          (ii) With respect to the Company, the Tenneco Entities
               and each of the Tenneco Entities' Subsidiaries, except as set
               forth in SCHEDULE 5.1(U), (A) no audit of any Tax Return is in
               progress or pending or, to the Knowledge of the Company,
               threatened, (B) no waiver of any statute of limitations has been
               given and is in effect with respect to the assessment of any Tax
               and (C) no deficiency has been assessed for any Tax by any
               Governmental Authority.
<PAGE>
                         (iii) Set forth in SCHEDULE 5.1(U) is a list of all
               current deficiencies asserted and assessments made by the IRS or
               the state equivalent with respect to the Tenneco Entities and the
               Tenneco Entities' Subsidiaries which deficiencies and assessments
               have not been paid, settled, withdrawn, overturned or dismissed.

                          (iv) True, correct and complete copies of all notices
               of deficiencies, assessments, audit reports, closing agreements
               with and other notices from any taxing authority for all years
               with respect to which the statute of limitations has not expired
               will be delivered to the Buyer prior to the Initial Closing Date.

                           (v) Neither the Company, the Tenneco Entities nor any
               of the Tenneco Entities' Subsidiaries has adopted a plan of
               complete liquidation and no consent has been filed on behalf of
               the Company, the Tenneco Entities or any of the Tenneco Entities'
               Subsidiaries pursuant to Section 341(f) of the Code or any
               predecessor provision.

                          (vi) The Company, the Tenneco Entities and the Tenneco
               Entities' Subsidiaries have collected all sales and use Taxes
               required to be collected, and have remitted, or will remit on a
               timely basis, such amounts to the appropriate Governmental
               Authorities where the failure to collect or remit would in the
               aggregate have a Material Adverse Effect, or have been furnished
               properly completed exemption certificates for all exempt
               transactions. Each of the Company, the Tenneco Entities and the
               Tenneco Entities' Subsidiaries has maintained in its possession
               all records and supporting documents required by applicable sales
               Tax statutes and regulations regarding the collection and payment
               of all sales and use Taxes required to be collected and paid over
               and regarding all exempt transactions for all periods open under
               the applicable statutes of limitations as of the Initial Closing
               Date.

                         (vii) The liabilities for Taxes reflected in the
               Balance Sheet set forth on SCHEDULE 5.1(F) are accurate and the
               amounts reflected for Taxes therein are sufficient for the
               payment of all accrued, unpaid or deferred Taxes of the Tenneco
               Entities and the Tenneco Entities' Subsidiaries for all periods
               ended on or prior to December 31, 1995, whether or not disputed.

                        (viii) The Company (a) has not been a member of an
               affiliated group filing a consolidated federal income Tax Return
               (other then a group the common parent of which is the Company)
               and (b) has no liability for Taxes of any Person (other than the
               Company, the
<PAGE>
               Tenneco Entities and the Tenneco Entities' Subsidiaries) under
               U.S. Treasury regulation ss. 1.1502-6 (or any similar provision
               of state, local or foreign law), as a transferee or successor, by
               contract or otherwise.

                          (ix) Neither the Company nor the Tenneco Entities is a
               United States real property holding corporation within the
               meaning of Section 897 of the Code, or will have been a U.S. real
               property holding corporation within the five years preceding the
               date hereof or the Initial Closing Date. The shares of capital
               stock of the Tenneco Entities acquired by the Company pursuant to
               the Stock Purchase Agreement are not United States real property
               interests within the meaning of Section 897 of the Code.

                           (x) The Company and the Tenneco Entities will
               promptly notify or arrange for the notification of the Buyer of
               any event materially affecting the continuing accuracy of any
               representation in this Section 5.1(u) between the date hereof and
               the Initial Closing Date.

The foregoing representations and warranties contained in this Section 4.1(u)
shall not apply to any Taxes attributable to any consolidated Tax Return filed
or required to be filed by El Paso or by Tenneco, Inc. as the common parent or
parent corporation of a group including the Tenneco Entities or the Tenneco
Entities' Subsidiaries.

               (v)  ENVIRONMENTAL MATTERS.  (i) Except as set forth on
        SCHEDULE 5.1(V), other than exceptions to the following
        that, individually or in the aggregate, would not reasonably
        be expected to have a Material Adverse Effect:

                           (A) The Company, the Tenneco Entities, the Tenneco
               Entities' Subsidiaries and, to the Knowledge of the Company, the
               Investments are in compliance with all applicable Environmental
               Laws; neither the Company, the Tenneco Entities nor any of the
               Tenneco Entities' Subsidiaries has received any written

        execution, delivery and performance by the Buyer of this Agreement and
        the Securityholders Agreement and the consummation by it of the
        transactions contemplated hereby and thereby. This Agreement and the
        Securityholders Agreement have been duly executed and delivered by the
        Buyer and, assuming due authorization, execution and delivery by the
        parties other than the Buyer hereto and thereto, constitute the legal,

        bankruptcy, insolvency, reorganization, moratorium or other laws
        relating to or limiting creditors' rights generally or by equitable
        principles relating to enforceability.

               (c) NO CONFLICT. Neither the execution and delivery of this
        Agreement and the Securityholders Agreement nor the performance by the
        Buyer of the transactions contemplated hereby and thereby, including

        any obligation under any mortgage, indenture, deed of trust, lease,
        contract, agreement, license or other instrument or violate any
        provision of any law, order, judgment, decree, restriction or ruling of

        distribution of any of the Company Shares. The Buyer acknowledges that
        it has such knowledge and experience in financial and business matters
        that it is capable of evaluating the merits and risks of purchasing the
        Company Shares, making an informed investment decision and of bearing
        the economic risk of the purchase of the Company Shares.

               (e) LITIGATION. No action, claim, suit or legal proceeding is now
        pending, or, to the knowledge of the Buyer, threatened, against the

        commission, agency or instrumentality of any Federal, state or local
        government or of any agency or subdivision thereof, or before any
        arbitrator or panel of arbitrators, which would adversely affect the
        Buyer's ability to perform the obligations under this Agreement, the
        Securityholders Agreement and other documents related hereto and thereto
        to which the Buyer is a party.

               (f) OWNERSHIP OF BUYER SUBORDINATED NOTE. On the date of any

        actions of the Company.

        or warranty of the Buyer contained in this Agreement contains any untrue
        statement of a material fact or omits to state a material fact necessary

        Subsidiaries intact and to keep available the services of the present
        employees and agents of the Tenneco Entities and the Tenneco Entities'
        Subsidiaries and to preserve the good will of customers, suppliers,
        employees, agents and sales representatives, distributors and others
        having business relations with the Tenneco Entities and the Tenneco
        Entities' Subsidiaries and no change will be made in existing practices
        relating to profit sharing, bonuses or commissions;

               (j) Each of the Company, the Tenneco Entities and the Tenneco

Subsidiaries, it is understood that the Company's obligation with respect
thereto is only to use all reasonable efforts to cause El Paso to cause the
Tenneco Entities and the Tenneco Entities' Subsidiaries to observe and comply
with such covenants.

               6.2. ACCESS TO INFORMATION CONCERNING PROPERTIES AND RECORDS;
CONFIDENTIALITY. (a) During the period commencing on the date hereof and ending

efforts to cause El Paso and its Affiliates to, and to cause the Tenneco

afford to the Buyer, its counsel, accountants and other professional advisers
reasonable access during normal business hours to the offices, plants,
properties, contracts, books and records of the Company, the Tenneco Entities
and the Tenneco Entities' Subsidiaries (and permit the Buyer and its counsel,
accountants and other authorized representatives to make copies of such
contacts, books and records at their own expense), in order that the Buyer may
have the full opportunity to make such reasonable investigations as it desires
to make of the affairs of the Company, the Tenneco Entities and the Tenneco
Entities' Subsidiaries, PROVIDED that no investigation pursuant to this SECTION
7.2 will affect any representations or warranties or the conditions to the
obligations of the parties hereto to consummate the purchase of the Company
Shares as contemplated hereby or the other transactions contemplated hereby. The
Company agrees that it will, and will cause the Tenneco Entities and the Tenneco
Entities' Subsidiaries and their respective officers, accountants and other
professional advisers, to, furnish to the Buyer such additional information as
the Buyer may from time to time reasonably request.

               (b) The Buyer agrees that it will, and will cause its officers,
employees, advisors and representatives to, hold in strict confidence all data
and information obtained from the Company, the Tenneco Entities or any of the
Tenneco Entities' Subsidiaries or on their behalf (other than information which
(i) is or becomes publicly available or (ii) which was already in the possession
of the Buyer, in each case other than as a result of a breach by the Buyer or
any of its officers, employees, advisors and representatives of this covenant or
other confidentiality agreement or legal or fiduciary obligation of secrecy to
the Company, the Tenneco Entities or any of the Tenneco Entities' Subsidiaries)
and will not, and will insure that such other persons do not, disclose such data
and information to others without the prior written consent of the Company,
except that the
<PAGE>
Buyer may provide such data and information in response to legal process or
applicable governmental regulations, but only that portion of the data and
information which, in the opinion of counsel for the Buyer, is legally required
to be furnished, and PROVIDED that the Buyer notifies the Company in writing of
its obligation to provide such confidential data and information and fully
cooperate with the Company to protect the confidentiality of such data and
information.

               6.3. RELEASES. Each party hereto agrees that it will not, without
the consent of the Buyer and the Company, issue any press release or make any
other public statement or disclosure with respect to the transactions
contemplated hereby or their terms.

               6.4. FURTHER ACTIONS. Subject to the terms and conditions
contained herein, each of the parties hereto agrees to use all reasonable
efforts promptly to take, or cause to be taken, all actions and to do, or cause
to be done, all things necessary, proper or advisable to consummate and make
effective the transactions contemplated by this Agreement, including using its
reasonable efforts to satisfy the conditions precedent to the obligations of the
parties hereto, to obtain all necessary waivers, consents and approvals, to
effect all necessary registrations and filings and to proceed with the Initial
Closing as expeditiously as practicable; PROVIDED that this obligation will not
require any party to take any action materially adverse to such party,
including, without limitation, agreeing to divest or hold separate any assets,
and PROVIDED FURTHER that no contract or other agreement will be amended to
increase the amount payable thereunder or to otherwise modify the terms thereof
in a manner adverse to the Company, the Tenneco Entities or any of the Tenneco
Entities' Subsidiaries in order to obtain any such consent, approval,
authorization or otherwise without first obtaining the written approval of the
Buyer.

               6.5. APPLICATION OF PROCEEDS. The payments to be made by the
Buyer pursuant to Section 1.2 shall be used by the Company exclusively for the
purpose of paying a portion of the purchase price for the shares of the Tenneco
Entities pursuant to the Stock Purchase Agreement.

               6.6. OPTION SHARES. At all times prior to the earlier of the
expiration of the Exercise Period without the Option having been exercised or
the issuance of the Option Shares, the Company shall reserve and keep available
for issuance pursuant to the Option a number of duly authorized shares of Common
Stock equal to the number of Option Shares.

                          ARTICLE VIII INDEMNIFICATION

               8.1. INDEMNIFICATION BY THE COMPANY. Subject to the limitations
set forth in Sections 8.6(a) and (b), the Company hereby agrees to indemnify the
Buyer and its Affiliates, and each of their respective officers, directors,
employees and representatives (each a "BUYER INDEMNIFIED PARTY" and collectively
the "BUYER INDEMNIFIED PARTIES") against, and agrees to protect, save and keep
harmless the Buyer Indemnified Parties from payment, and hereby assumes
liability for the payment, of any and all liabilities (including liabilities for
Taxes), obligations, losses, damages, penalties, claims, actions, suits,
judgments or settlements of any nature or kind, whether known or unknown,
absolute or contingent, accrued or unaccrued, realized or unrealized, direct or
indirect, liquidated or unliquidated and including all costs, expenses and
disbursements (including reasonable cost of investigation by, and reasonable
attorneys', accountants' and expert witnesses' fees and expenses payable to,
third parties) (collectively, "LOSS" or "LOSSES"), arising out of, resulting
from or in connection with (a) any breach by the Company of a representation or
warranty contained herein or in any certificate delivered pursuant to Section
7.1 or (b) any failure by the Company to perform any agreement or covenant
contained herein.

               8.2. INDEMNIFICATION BY THE BUYER. Subject to the limitations set
forth in Sections 8.6(a) and (b), the Buyer hereby agrees to indemnify the
Company and its officers, directors, and employees, and their Affiliates and
representatives (each a "COMPANY INDEMNIFIED PARTY" and collectively the
"COMPANY INDEMNIFIED PARTIES") against, and agrees to protect, save and keep
harmless the Company Indemnified Parties from payment, and hereby assumes
liability for the payment, of any or all Losses or Loss arising out of or
resulting from (a) any breach by the Buyer of a representation or warranty
contained herein or in any certificate delivered pursuant to Section 7.2 or (b)
any failure by the Buyer to perform any agreement or covenant contained herein.
<PAGE>
               8.3. PROCEDURE FOR GENERAL CLAIMS. (a) GENERAL CLAIMS BY THE
BUYER. The Buyer will give prompt written notice to the Company of any claim or
event other than a Third Party Claim (as defined in SECTION 8.4) with respect to
which the Buyer believe it is or may be entitled to indemnification pursuant to
SECTION 8.1 hereof (a "NOTICE OF CLAIM"), PROVIDED that the failure to provide a
Notice of Claim shall not relieve the Company of its obligations under this
Section 8 except to the extent the Company is actually prejudiced thereby. The
Notice of Claim will state the nature and basis of such claim or event, the
amount thereof to the extent known and the basis of the Buyer's belief that a
Buyer Indemnified Party is or may be entitled to indemnification with respect
thereto. The Company shall be entitled, at its option, to satisfy its
indemnification obligations with respect to any claim under this Section 8.3(a)
either (i) in cash, (ii) in shares of Common Stock or (iii) with an
Indemnification Note, PROVIDED that as long as any amounts remain outstanding
under the Credit Agreement, the Company shall satisfy its indemnity obligations
in Common Stock. If the Company elects to satisfy its obligations in shares of
Common Stock, the number of shares of Common Stock to be delivered in
satisfaction of such indemnification obligation shall be equal to the dollar
amount of the Loss or Losses divided by the Fair Market Value per Share as of
the date the Notice of Claim is delivered. For the purposes of this Section
8.3(a), the "FAIR MARKET VALUE PER SHARE" shall be the Fair Market Value (as
such term is defined in the Securityholders Agreement) per share of Common
Stock. If the Company and such Buyer Indemnified Party are unable to reach an
agreement on a Fair Market Value per Share within 30 days following the receipt
by the Company of the Notice of Claim, the Company and such Buyer Indemnified
Party shall engage a nationally-recognized investment banking firm familiar with
the oil and gas industry in the Gulf Coast/U.S. Gulf of Mexico and as mutually
agreed by them to determine as expeditiously as possible the aggregate fair
market value of all outstanding shares of Common Stock as if the entire Company
were being sold in a private sale and such aggregate market value for all
outstanding shares of Common Stock divided by the number of shares of Common
Stock outstanding immediately prior to the issuance of shares under this Section
8.3(a) shall be the Fair Market Value per Share. The fees of such investment
banking firm shall be paid by the Company.

               (b) GENERAL CLAIMS BY THE COMPANY. The Company will give prompt
written notice to the Buyer with respect to any claim or event with respect to
which the Company believes a Company Indemnified Party is or may be entitled to
indemnification pursuant to SECTION 8.2 hereof. The notice will state the nature
and basis of said claim or event, the amount thereof to the extent known, and
the basis of the Company's belief that a Company Indemnified Party is or may be
entitled to indemnification with respect thereto.
<PAGE>
                     8.4. PROCEDURE FOR THIRD PARTY CLAIMS.

               (a) CLAIMS BY THE BUYER AND THE COMPANY. The Buyer, on behalf of
itself or any Buyer Indemnified Party, on the one hand, or the Company, on
behalf of itself or any Company Indemnified Party on the other hand (the
"INDEMNIFIED PARTY"), will give prompt written notice to the party from whom
indemnification is sought (the "INDEMNIFYING PARTY") pursuant to SECTION 8.1 OR
SECTION 8.2 hereof of any and all Losses or Loss arising out of or resulting
from any claim, action, suit or proceeding brought by any third party relating
to litigation, administrative proceedings or similar actions (collectively,
"THIRD PARTY CLAIMS") with respect to which such Indemnified Party believes it
is entitled to indemnification hereunder, together with an estimate of the
amount in dispute thereunder and a copy of any claim, process, legal pleadings
or correspondence with respect thereto received by the Indemnified Party. In
connection with any such Third Party Claim, the Indemnifying Party may, at its
election and expense, participate in the defense of such Third Party Claim and
no such Third Party Claim will be settled without the consent of the
Indemnifying Party, which will not be unreasonably withheld. With respect to any
Third Party Claim relating solely to the payment of money damages and which will
not result in the Indemnified Party becoming subject to injunctive or other
equitable relief, within 30 days of receipt of notice of such Third Party Claim,
the Indemnifying Party may, by written notice to the Indemnified Party, assume
the defense of such Third Party Claim through counsel of its own choosing which
is reasonably acceptable to the Indemnified Party, which will not be
unreasonably withheld, and with all expenses thereof to be paid by the
Indemnifying Party, in which event the Indemnifying Party will control the
defense of such Third Party Claim and the Indemnified Party may participate in
the defense thereof with all expenses thereof to be paid by such Indemnified
Party, PROVIDED that such Indemnified Party will have the right to employ
separate counsel to represent such Indemnified Party if, in such Indemnified
Party's reasonable judgment, a conflict of interest between the Indemnifying
Party and such Indemnified Party exists with respect to such Third Party Claim
in which event all reasonable expenses of such separate counsel will be paid by
the Indemnifying Party. If the Indemnifying Party fails to assume the defense of
such Third Party Claim by delivering a written notice of the Indemnifying
Party's intention to assume such defense within 30 days of receipt of the
initial notice thereof, or thereafter abandons or fails to diligently pursue
such defense, the Indemnified Party may assume such defense. In the event the
Indemnifying Party exercises its right to undertake the defense against any such
Third Party Claim as provided above, the Indemnified Party will cooperate with
the Indemnifying Party in such defense and make available to the Indemnifying
Party all pertinent records, materials and information in its possession or
under its control relating thereto as is reasonably required by the Indemnifying
Party, with all expenses incurred in connection therewith to be paid by the
Indemnifying Party. Similarly, in
<PAGE>
the event the Indemnified Party is, directly or indirectly, conducting the
defense against any such Third Party Claim as provided above, the Indemnifying
Party will cooperate with the Indemnified Party in such defense and make
available to the Indemnified Party all such records, materials and information
in the Indemnifying Party's possession or under the Indemnifying Party's control
relating thereto as is reasonably required by the Indemnified Party, with all
expenses incurred in connection therewith to be paid by the Indemnifying Party.
Notwithstanding anything in this SECTION 8.4 to the contrary, however, in the
event of a claim with respect to which the Indemnifying Party has agreed to
assume the defense thereof, the Indemnifying Party will not thereafter be
entitled to dispute, and hereby agrees not to dispute, the Indemnified Party's
right to indemnification therefor pursuant to SECTION 8.1 or SECTION 8.2 hereof
or any subsequent claims of the Indemnified Party with respect to such Third
Party Claim.

               (b)  SETTLEMENT OR DECISION OF THIRD PARTY CLAIMS.  The
Indemnifying Party will not, without the written consent of the Indemnified
Party, (i) settle or compromise any Third Party Claim or consent to the entry of
any judgment which does not include as an unconditional term thereof the
delivery by the claimant or plaintiff to the Indemnified Party of a written
release from all liability in respect of such Third Party Claim or (ii) settle
or compromise any Third Party Claim in any manner that may, in the reasonable
judgment of the Indemnified Party, adversely affect the Indemnified Party
(including without limitation any settlement or compromise that includes any
admission of negligence or other malfeasance on the part of the Indemnified
Party). Similarly, no Third Party Claim which is being defended in good faith by
the Indemnified Party in accordance with the terms of this Agreement will be
settled by the Indemnified Party without the written consent of the Indemnifying
Party, which consent will not be unreasonably withheld. Upon the settlement or
compromise of any Third Party Claim, the order of a court of competent
jurisdiction or arbitrator with respect thereto or the final, non-appealable
order of any appellate court with respect thereto, as the case may be, any
resulting settlement, award, damages or judgment will be paid (i) in the case of
any such Third Party Claim with respect to which the Indemnifying Party is the
Buyer, by the Buyer and (ii) in the case of any such Third Party Claim with
respect to which the Company is the Indemnifying Party, by the Company.

               8.5.  INDEMNIFICATION MATTERS.  In cases where any
Indemnified Party has made a prior payment with respect to any liability that is
the subject of indemnification under SECTION 8.1 OR 8.2 hereof, the Indemnifying
Party will also pay interest on such funds at a rate per annum equal to the
published prime rate of The Chase Manhattan Bank in effect from time to time
during the relevant period, such interest to be due from the date of such prior
payment to the date of payment of any such funds by the Indemnifying Party. The
parties agree that payments by an
<PAGE>
Indemnifying Party made under SECTION 8.1 OR 8.2 hereof will be treated as an
adjustment to the Purchase Price for Tax purposes. The provisions of this
Article VII will not be deemed to be a limitation or waiver of any other remedy
afforded by law to the Buyer or the Company for indemnification under SECTION
8.1 OR 8.2 hereof.

               8.6.  GENERAL PROVISIONS.

               (a) LIMITATIONS ON INDEMNIFICATION. (i) Notwithstanding anything
in this ARTICLE VII to the contrary other than the next succeeding sentence, an
Indemnifying Party will be required to indemnify and hold harmless an
Indemnified Party under SECTION 8.1 or SECTION 8.2 hereof with respect to any
Loss or Losses incurred by any such Indemnified Party only to the extent that
the aggregate amount of all Losses of the applicable Indemnified Parties (that
is, either the Buyer Indemnified Parties or the Company Indemnified Parties, as
the case may be) exceeds $2,000,000 in the aggregate, in which event the
Indemnifying Party will only be liable for the excess of such Loss or Losses
over $2,000,000. The foregoing limitations will not be applicable to any willful
breach by any party of any representation, warranty, covenant or agreement
hereunder.

               (ii) With respect to any claim by the Buyer Indemnified Parties,
Losses (a) will include any Loss or Losses incurred by the Buyer which arises
from or relates to the diminution in the value per share of Common Stock caused
by any breach by the Company of a representation or warranty contained herein
and (b) will fully take into account the diminution in value of the Company
Shares held by the Buyer Indemnified Parties in the aggregate (determined by
reference to the number of shares of Common Stock outstanding on a fully diluted
basis) resulting from the indemnification payment made by the Company (whether
made in cash, in stock or in the form of a note). As an example of the operation
of clause (b) of the preceding sentence, if the Losses suffered by the Buyer
Indemnified Parties prior to the operation of clause (b) were $100,000 and the
Buyer Indemnified Parties in the aggregate owned 90% of the total issued and
outstanding Common Stock at the time of delivery of their Notice of Claim, the
indemnification payment made by the Company pursuant to this ARTICLE VII would
be $1 million (or its equivalent in stock if paid in stock pursuant to Section
8.3). Notwithstanding anything to the contrary in this Section 8.6, for the
purpose of determining whether a Loss or Losses to a Buyer Indemnified Party
resulting from a diminution in the value per share of Common Stock exceeds
$2,000,000, such Loss or Losses shall be measured as the amount of such Loss or
Losses without giving effect to clause (b) of this Section 8.6(a)(ii). As an
example of the operation of the preceding sentence, total Losses to the Company
of $1,800,000 would not be indemnifiable by the Company to the Buyer Indemnified
Parties despite the fact that the operation of clause (b) of this Section
8.6(a)(ii) would
<PAGE>
otherwise have caused the indemnification payment to exceed
$2,000,000.

               (b) TERMINATION OF INDEMNIFICATION. The obligations to indemnify
and hold harmless an Indemnified Party pursuant to SECTIONS 8.1 AND 8.2 will
terminate with respect to any theretofore unasserted claim when the applicable
representation or warranty terminates pursuant to SECTION 5.3; PROVIDED,
HOWEVER, that such obligations to indemnify and hold harmless will not terminate
with respect to any item as to which the Person to be indemnified will have,
before the expiration of the applicable period, previously made a claim by
delivering a notice pursuant to SECTION 8.3 or SECTION 8.4 hereof to the
Indemnifying Party.


                            ARTICLE IX MISCELLANEOUS

               9.1.  TERMINATION AND ABANDONMENT.  (a)  GENERAL.  This

        decree or ruling or taken any other action restraining, enjoining or
        otherwise prohibiting the transactions contemplated hereby or with
        respect to any of the other Transactions and such order, decree, ruling
        or other action will have become final and nonappealable; or

               (iii) if the Initial Closing will not have occurred by January
        31, 1997, despite the reasonable efforts of the parties hereto to close.

               (b) PROCEDURE UPON TERMINATION. In the event of the termination
and abandonment of this Agreement, written notice thereof will promptly be given
to the other parties hereto and this Agreement will terminate and the
transactions contemplated hereby will be abandoned without further action by any
of the parties hereto.

               9.2. FEES AND EXPENSES. If the transactions contemplated hereby

compliance with any representations, warranties, covenants or agreements
contained herein, and in any documents delivered or to be delivered pursuant to
this Agreement and in connection with the Initial and the Subsequent Closing

                                  LITIGATION
PLAINS RESOURCES:
            A settlement has been reached in a lawsuit between Nicklos Drilling
Company and Plains Resources et. al. The lawsuit stemmed from costs incurred
when drillpipe was stuck in the Boagni #1 well, which led to a total loss of the
wellbore, necessitating a redrill of the well. Tenneco Ventures' share of the
settlement, which includes Joint Interest Billings and legal costs, is $230,000.
This settlement will be paid in January of 1997.

GECKO:
            In late 1995, three employees of a storage tank rental firm were
killed while cleaning out one of their tanks that had previously been used on a
location in which Tenneco Ventures had a working interest. The problem stemmed
from the employees having been exposed to Hydrogen Sulfide (H2S). According to
the operator of the well, Gecko Operating, the tank was tested prior to being
moved from a well site and found to be free of any H2S contamination. The source
of the H2S was traced to wash water utilized by the employees in their own yard.
The water had reportedly been taken from a different tank in their yard and
neither the source water nor the tank water was connected in any way to Gecko's
operations. Despite this background, Tenneco Ventures has received word that a
lawsuit is being filed against Gecko which could subsequently expose Tenneco
Ventures' to the litigation. The potential liability of Tenneco Ventures, if
any, is unknown.

WEST DELTA 30:
            Tenneco Ventures has been advised that legal action is being pursued
by an individual as a result of injuries sustained while working at a platform
on the West Delta 30 block. The potential liability of Tenneco Ventures, if any,
is unknown.

MUSTANG ISLAND 847:
            In the Fall of 1995, a helicopter pilot under contract to OCS,
Tenneco Ventures' contract operator for the field, inadvertently stepped off
into a stairwell while tying down his aircraft on the B platform at Mustang
Island 847. The pilot reportedly received minor cuts, bruises and contusions,
was held overnight at a hospital for observation, and released. To Tenneco
Ventures' knowledge, no claims have been made or are
<PAGE>
pending relating to this incident, which is being identified as the only known
injury sustained on a property operated by Tenneco Ventures.

WEST COTE BLANCHE BAY
            Tenneco Ventures and Tenneco Gas Production Corporation ("TGPC")
have 7.19889% and 3.59890% working interests, respectively, in West Cote Blanche
Bay. In connection with those interests, Tenneco Ventures and TGPC are alleged
by Texaco Exploration and Production, Inc. ("Texaco") to owe a portion of $1.3
million, which represents total debt outstanding to Texaco from Benton Oil and
Gas Company of Louisiana, Tenneco Ventures and TGPC. Texaco has indicated that
it will pursue all available remedies to collect amounts owing. Management
believes that the likely exposure of Tenneco Ventures and TGPC does not exceed
$175,000, and efforts are underway with Texaco to resolve this dispute.

            Shortly after Tenneco Ventures Corporation acquired West Delta 30,
in the course of repairs to a flowline the personnel representing Seneca
Resources, the Operator, noticed small sheens occurring coincidentally with
movement of divers working on the bottom. To the best of their knowledge, the
personnel believe that the source was a pre-existing condition of the mudline
and the previous owner, Shell, was notified accordingly by Seneca.

                               ARTICLE I.

                              SUBSCRIPTION

            Section 1.1. SUBSCRIPTION FOR SHARES. Subject to the terms and
provisions of this Investment Agreement, the Investor hereby irrevocably
subscribes for and agrees to purchase 237.9868 Shares (the "Investor Shares") at
$3,151.4354 per Share. Such aggregate subscription price

                                  2
<PAGE>
(the "Subscription Price") shall be payable in part in cash and in part by the
delivery by the Investor to the Company of a promissory note in the form of that
attached hereto as Exhibit A (the "Note") and a Pledge Agreement pledging the
Investor Shares and other equity securities issued by the Company, in the form
of that attached hereto as Exhibit B (the "Pledge Agreement"). The amount of the
Note will be equal, at the option of the Investor, to a maximum of $249,200.00
(calculated by multiplying 40% by the $623,000.00 severance and retention bonus
payment due the Investor from Tenneco, the obligation to pay which has been
assumed by the Company). The Subscription Price will be paid promptly following
the receipt by the Investor of the severance and retention bonus payment
referred to above, net of applicable withholdings. Upon delivery of the
Subscription Price and the Pledge Agreement, the Company will issue the 237.9868
Investor Shares.

            Section 1.2. INDEMNIFICATION. The Investor understands and
acknowledges the meaning and legal consequences of the representations,
warranties and agreements made by the Investor in this Investment Agreement and
that the Company has relied upon such representations, warranties and
agreements, and the Investor hereby agrees to indemnify and hold harmless the
Company, and all directors, officers, employees, stockholders, agents and
representatives thereof, from and against any and all claims, demands, losses,
damages, expenses or liabilities (including without limitation attorneys' fees)
due to or arising out of a breach of any such representations, warranties or
agreements. Notwithstanding the foregoing, however, no representation, warranty
or agreement made herein by the Investor shall in any manner be deemed to
constitute a waiver of any rights available to the Investor under federal or
state securities laws.

                               ARTICLE II.

                      INVESTMENT CONSIDERATIONS AND
                REPRESENTATIONS, WARRANTIES AND COVENANTS

            Section 2.1. CERTAIN INVESTMENT CONSIDERATIONS. In addition to the
other information reviewed by the Investor in connection with the Investor's
evaluation of an investment in the Shares and in addition to the other
investment considerations set forth in this Investment Agreement, the Investor
understands and has carefully considered each of the following investment
considerations prior to the Investor's investment in the Investor Shares:

                                  3
<PAGE>
            (a) CONTROL BY THE FIRST RESERVE ENTITIES. Upon consummation of the
Ventures Companies Acquisition and the issuance and sale of the Shares under the
First Reserve Subscription Agreement and the Management Investors Subscription
Agreements (assuming all Management Investors' Shares offered thereby are fully
subscribed), (i) the First Reserve Entities will collectively own 9,519.4717
shares of Common Stock, representing 94.8426% of the then issued and outstanding
shares of Common Stock, and (ii) the Management Investors will collectively own
517.6542 shares of Common Stock, representing 5.1574% of the then issued and
outstanding shares of Common Stock. As a consequence thereof, the First Reserve
Entities will have voting control of the Company. Under the terms of the
Securityholders' Agreement, (i) the Board will consist of five members, three of
whom the First Reserve Entities will have the right to designate and two of whom
the Management Investors will have the right to designate, and (ii) all
Significant Transactions (as such term is defined in the Securityholders'
Agreement, and which term includes mergers and sales of assets) may be
authorized and effected only by a vote of at least a majority of the whole
Board. Because such a majority requires three members of the Board, the First
Reserve Entities will have the ability to control all Significant Transactions
by means of their three Board designees.

            (b) NO ASSURANCE OF PROFITS. The Investor recognizes that no
assurances of profits, ability to repay debt, cash distributions or capital
appreciation have been made or can be made regarding the Company.

            (c) INDEBTEDNESS AND CAPITAL STRUCTURE. In connection with the
consummation of the Ventures Companies Acquisition, the Company has entered into
a Credit Agreement among the Company, certain subsidiaries of the Company, as
subsidiary guarantors (the "Subsidiary Guarantors"), certain lenders
(collectively, the "Lenders"), and The Chase Manhattan Bank, as Administrative
Agent for the Lenders (the "Credit Agreement"). The Company has borrowed
approximately $61.2 million under the Credit Agreement to finance in part the
Ventures Companies Acquisition. Consequently, the Company has a substantial
level of outstanding indebtedness. Specifically, as a result of the Ventures
Companies Acquisition and related transactions, the Company has total
consolidated indebtedness for money borrowed of approximately $89.4 million and,
upon consummation of the subscriptions by the Management Investors, will have
stockholders' equity of approximately $31.6 million. The total debt-to-total
capitalization ratio of the Company upon the consummation of the Ventures
Companies Acquisition and the subscriptions by

                                  4
<PAGE>
the Management Investors is expected to be approximately .74 to 1.0 on a fully
consolidated basis.

            The indebtedness incurred in connection with the financing of the
Ventures Companies Acquisition will pose substantial risks to the holders of the
Shares. Such risks include, but are not limited to, the following: (i)
significant interest expense and principal repayment obligations will be
incurred by the Company; (ii) the ability of the Company to satisfy its
obligations and to reduce its debt will depend upon the Company's future
operating performance, general economic conditions, interest rates, future
prices of oil and gas, and other factors, including factors beyond the control
of the Company; (iii) the Company might not generate sufficient cash flow to pay
interest on or principal of the indebtedness under the Credit Agreement; (iv)
the indebtedness incurred will limit the Company's ability to effect future
financings or acquisitions or to take advantage of significant business
opportunities that may arise and may otherwise restrict corporate activities and
limit the Company's ability to withstand competitive pressures or adverse
economic conditions; and (v) the Company will have restrictions on operations
and use of available cash flow. In addition, as a result of the increased level
of indebtedness and related debt service obligations, the Company will be less
able to meet its obligations in the event of a downturn in the oil and gas
business generally or in the economy.

            (d) ASSET ENCUMBRANCES. The Company and the Subsidiary Guarantors
have granted to the Lenders liens on and security interests in substantially all
of their assets. In the event of a default under the Credit Agreement (whether
as a result of the failure to comply with a payment or other covenant, a
cross-default provision or otherwise), the Lenders, who have a prior, secured
claim on substantially all of the assets of the Company and the Subsidiary
Guarantors, may attempt to foreclose on their collateral, in which event the
Company's financial condition, and the value of the Shares would be materially
adversely affected.

            (e) RESTRICTIONS AND COVENANTS. The Credit Agreement contains
numerous financial and operating covenants, including restrictions on use of
available cash flow and restrictions on additional financings. Such covenants
and restrictions may limit the Company's ability to conduct its business. The
Company's ability to comply with the terms of the Credit Agreement (including
its ability to comply with such covenants) and to satisfy its other debt
obligations will depend, in part, on the future performance

                                  5
<PAGE>
of the Company and its subsidiaries. Such future performance will be subject to
prevailing economic conditions and to financial, business and other factors,
including factors beyond the control of the Company. In the event the Company
fails to comply with the various covenants contained in the Credit Agreement, it
could be declared in default thereunder and the debt thereunder could be
accelerated, in which event the Company's financial condition, and the value of
the Shares would be materially adversely affected.

            (f) INTEREST RATE SENSITIVITY. The indebtedness incurred under the
Credit Agreement will bear interest at rates which will fluctuate with the Prime
Rate and the Eurodollar rate (as defined therein). Any significant increase in
prevailing interest rates could have a material and adverse effect on the
Company's financial condition.

            (g) COMPETITION. The Company's business is highly competitive. A
number of United States and foreign entities will compete with the Company, and
many of the Company's competitors will have greater financial resources than the
Company.

            (h) ENVIRONMENTAL MATTERS. As a result of the Ventures Companies
Acquisition, the Company is subject to extensive federal, state and local
environmental laws, regulations and permit requirements. The Company's business
will inherently expose it to various risks, such as the potential for harmful
substances escaping into the environment and causing damage or injury.
Significant costs could be incurred on account of environmental laws or
regulations in the future, and the Company cannot predict the impact on its
operations of new or changed laws or regulations.

            (i) TRANSFER RESTRICTIONS; COMPANY CALL. Pursuant to the terms of
the Securityholders' Agreement, the Investor may not sell, transfer or otherwise
dispose of the Shares being purchased by the Investor until the earlier of (i)
five years after the date hereof and (ii) the occurrence of a Qualified Public
Offering (as defined in the Securityholders' Agreement). In addition, the
Securityholders' Agreement generally provides that upon the termination of the
Investor's employment with the Company, the Company has the option, on the terms
and subject to the conditions of the Securityholders' Agreement, to purchase the
Shares being purchased by the Investor pursuant to this Investment Agreement.

                                  6
<PAGE>
            Section 2.2. REPRESENTATIONS, WARRANTIES AND COVENANTS. The
Investor, by executing this Investment Agreement, acknowledges, covenants,
agrees, represents and warrants that:

            (1) INVESTMENT FOR OWN ACCOUNT. The Investor Shares are being
acquired by the Investor solely for the Investor's own account, for investment
purposes only and not with a view to, and not for offer or sale in connection
with, any distribution or resale of the Investor Shares, and no one other than
the Investor has or will have any beneficial interest in the Investor Shares.

            (2) ADEQUATE INFORMATION. The Company has made available and the
Investor has fully and completely reviewed all such information that the
Investor considers necessary or appropriate to evaluate the risks and merits of
an investment in the Investor Shares (including without limitation, the Stock
Purchase Agreement, the First Reserve Subscription Agreement, the
Securityholders' Agreement and the Credit Agreement). The Investor has not
distributed this Investment Agreement or such information to any person or
entity other than the Investor's legal and tax advisors, if any, and no one
other than such persons and entities and the Investor has used this Investment
Agreement or such information.

            (3) OPPORTUNITY TO QUESTION. The Investor has had the opportunity to
question, and has questioned, to the extent the Investor has deemed necessary or
appropriate, representatives of the Company so as to receive answers and verify
information obtained in the Investor's examination of the Company, including
without limitation the information referred to in paragraph (2) of this Section
2.2 and all other documents or information that the Investor has reviewed in
relation to his or her investment in the Investor Shares.

            (4) NO OTHER REPRESENTATIONS. No oral or written representations
have been made to the Investor in connection with the Investor's acquisition of
the Investor Shares that were in any way inconsistent with the information
reviewed by the Investor.

            (5) KNOWLEDGE AND EXPERIENCE. The Investor has such knowledge and
experience in financial, tax and business matters, including without limitation
substantial experience in evaluating and investing in common stock and other
securities (including without limitation the common stock and other securities
of new and speculative companies and companies engaged in oil and gas
exploration and production), so as to enable the Investor to utilize the
information

                                  7
<PAGE>
referred to in paragraph (2) of this Section 2.2 and all other information made
available to the Investor in order to evaluate the risks and merits of an
investment in the Investor Shares and to make an informed investment decision
with respect thereto. In addition, the Investor has been advised to consult with
an attorney regarding legal matters concerning the Company and to consult with a
tax advisor regarding the tax consequences of investing in the Company and
purchasing the Investor Shares.

            (6) INDEPENDENT DECISION. The Investor is not relying on the Company
or any references to any legal or other opinion in the materials reviewed by the
Investor with respect to the tax considerations of the Investor relating to an
investment in the Investor Shares pursuant to Section 1.1 hereof. The Investor
has relied solely on its own examination and independent investigation of the
Company, the Investor Shares and Securityholders' Agreement in making its
decision to acquire the Investor Shares.

            (7) FINANCIAL CONDITION. The Investor's financial condition and
income are such that (i) the Investor is under no present need to dispose of any
portion of the Investor Shares to satisfy any existing or contemplated
undertaking or indebtedness and (ii) the Investor is able to bear the economic
risk of investment in the Investor Shares, including the risk of losing the
entire investment and the risk of not being able to sell or transfer any of the
Investor Shares for an indefinite period of time. In this regard, the Investor
recognizes that the Securityholders' Agreement contains a prohibition on any
transfer of such Shares for a period of five years from the date of issuance.

            (8) RESTRICTED SECURITIES. The Investor understands that the
Investor may be required to bear the economic risk of investment in the Investor
Shares for an indefinite period of time because the Investor Shares (a) may not,
without full compliance with the registration and prospectus delivery
requirements of the Securities Act and applicable Blue Sky Laws, be offered,
sold or delivered except in a transaction exempt from, or not subject to, the
registration and prospectus delivery requirements of the Securities Act and
applicable Blue Sky Laws and (b) are additionally subject to all of the
prohibitions, restrictions and other limitations on transfer set forth in the
Securityholders' Agreement. The Investor understands that the Company has no
obligation to cause or permit the registration of any of the Investor Shares
under the Securities Act or any Blue Sky Laws except as may be set forth in the
Securityholders' Agreement.

                                  8
<PAGE>
            (9) RESTRICTIONS ON RESALE OR TRANSFER. The Investor will not
transfer or pledge any or all of the Investor Shares in violation of the
Securityholders' Agreement or the Securities Act or any applicable Blue Sky Laws
and in the event that the Investor pledges any of the Investor Shares (to the
extent permitted under the Securityholders' Agreement, the Securities Act and
any applicable Blue Sky Laws), the Investor will comply with the
Securityholders' Agreement in connection therewith, will advise the pledgee of
the transfer restrictions imposed on the Investor Shares by this Investment
Agreement and will use its best efforts to obtain an undertaking from such
pledgee not to transfer such Investor Shares in violation of the Securities Act
or applicable Blue Sky Laws.

            (10) RESTRICTIVE LEGEND. The certificates from time to time
evidencing the Investor Shares may, at the Company's sole option, bear a legend
that provides that the Investor Shares have not been registered under the
Securities Act or any applicable Blue Sky Laws and that the Investor Shares may
not be transferred unless the Company is first delivered a legal opinion,
satisfactory to the Company in its sole discretion, to the effect that such
transfer may be made without compliance with the registration and prospectus
delivery requirements of the Securities Act and applicable Blue Sky Laws. Such
legal opinion shall be given by counsel satisfactory to the Company in its sole
discretion, at the Investor's expense. Under the terms of the Securityholders'
Agreement, the certificates representing the Shares are required to bear the
following legend:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
      ANY APPLICABLE STATE SECURITIES LAWS, AND ARE SUBJECT TO THE PROVISIONS
      (INCLUDING THE RESTRICTIONS ON TRANSFER) SET FORTH IN THAT CERTAIN
      SECURITYHOLDERS' AGREEMENT DATED AS OF DECEMBER 31, 1996 AMONG DOMAIN
      ENERGY CORPORATION (THE "COMPANY"), FIRST RESERVE FUND VII, LIMITED
      PARTNERSHIP AND THE INDIVIDUALS AND TRUSTS SIGNATORY THERETO, AS SUCH
      AGREEMENT MAY BE AMENDED (AS AMENDED, IF AMENDED, THE "SECURITYHOLDERS'
      AGREEMENT"), A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.
      THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT (AND THE HOLDER OF
      THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE, AGREES THAT SUCH
      SECURITIES MAY NOT AND WILL NOT) BE TRANSFERRED, SOLD, ASSIGNED, PLEDGED,
      HYPOTHECATED OR OTHERWISE

                                  9
<PAGE>
      DISPOSED OF (1) EXCEPT IN COMPLIANCE WITH THE SECURITYHOLDERS' AGREEMENT
      AND (2) EXCEPT AS OTHERWISE PROVIDED IN THE SECURITYHOLDERS' AGREEMENT,
      UNLESS AND UNTIL SUCH SECURITIES ARE REGISTERED UNDER THE SECURITIES ACT
      AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL FOR THE
      HOLDER SATISFACTORY TO THE COMPANY IS OBTAINED TO THE EFFECT THAT SUCH
      REGISTRATION IS NOT REQUIRED. ADDITIONALLY, IF THE HOLDER IS A CITIZEN OR
      RESIDENT OF ANY COUNTRY OTHER THAN THE UNITED STATES, OR THE HOLDER
      DESIRES TO EFFECT ANY SUCH TRANSACTION IN ANY SUCH COUNTRY, THE COMPANY
      MUST BE FURNISHED WITH A SATISFACTORY OPINION OR OTHER ADVICE OF COUNSEL
      FOR THE HOLDER THAT SUCH TRANSACTION WILL NOT VIOLATE THE LAWS OF SUCH
      COUNTRY."

The Investor has read and understands the restrictions on transfer set forth in
such legend and in the Securityholders' Agreement and agrees to comply with all
such restrictions.

            (11) FURTHER ACTIONS. The Investor shall, at the Company's expense,
take all further actions necessary to facilitate the issuance of the Investor
Shares to the Investor under an appropriate exemption from registration under
the Securities Act and applicable Blue Sky Laws, including without limitation
providing the Company with such information as the Company may require to
complete a Form D and any related or similar forms or applications required
under the Securities Act or applicable Blue Sky Laws.

            (12) AUTHORIZATION; LEGAL COMPETENCE. The Investor has full power
and authority to execute this Investment Agreement and to invest in the Investor
Shares, and this Investment Agreement constitutes the valid and legally binding
obligation of such Investor, enforceable against such Investor in accordance
with its terms.

            (13) ACCREDITED INVESTOR; BLUE SKY LAWS. The Investor is an
"accredited investor" as that term is defined in Rule 501 of Regulation D
promulgated under the Securities Act of 1933, as amended. The Investor
understands that no commissioners of securities or equivalent officials of any
state have made any finding or determination relating to the fairness of an
investment in the Shares and that no such person has recommended or endorsed the
Shares. The Investor is a "sophisticated investor" as such term is defined by
the Texas Blue Sky Regulations relating to limited offering exemptions, in that
the purchase of the Investor Shares by the Investor does not exceed 20% of the
Investor's net worth

                                  10
<PAGE>
on the date hereof, and the Investor has knowledge of finance, securities and
investments, generally.

            This Amended and Restated Management Investor Subscription Agreement
amends, supersedes and restates in its entirety the Management Investor
Subscription Agreement by the Investor for the benefit of the Company dated as
of December 31, 1996. The provisions hereof shall inure to the benefit of the
Company, its successors and assigns and shall be binding upon the Investor, its
legal representatives, successors and assigns.

which failure amounts to a material neglect of duties to the Company or any of
its affiliates; and "Good Reason" shall mean, except as otherwise provided in an
employment agreement between the Company and the Executive, (x) any material

responsibilities (except in connection with the termination of the Executive's
employment for Cause, as a result of Permanent Disability, as such term is

sentence, the definitions in any employment agreement in effect on the date
hereof between the Company and the Executive of "Cause" and "Good Reason" shall

immediately preceding sentence and shall be deemed incorporated by reference in

termination of employment by the Executive at age 62 or older (or such other age
as may be approved by the Board of Directors of the Company) after having been
employed by the Company for at least three years after the date hereof.

any rights hereunder. If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition. The
Executive shall remain liable for any deficiency if the proceeds of any sale or
other disposition of Collateral are insufficient to pay the Obligations and the
fees and disbursements of any attorneys employed by the Company to collect such
deficiency.

terms or provisions of this Agreement may be waived, amended, supplemented or
otherwise modified except by a written instrument executed by the Executive and
the Company, PROVIDED that any provision of this Agreement may be waived by the

deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default ot Event of Default or in any breach of any of the terms and conditions

remedies provided by law.

            (a) NO ASSURANCE OF PROFITS. The Investor recognizes that no
assurances of profits, ability to repay debt, cash distributions or capital
appreciation have been made or can be made regarding the Company.

            (b) INVESTMENT FOR OWN ACCOUNT. The Investor Shares are being
acquired by the Investor solely for the Investor's own account, for investment
purposes only and not with a view to, and not for offer or sale in connection
with, any distribution or resale of the Investor Shares, and no one other than
the Investor has or will have any beneficial interest in the Investor Shares.

            (c) ADEQUATE INFORMATION. The Company has made available and the
Investor has fully and completely reviewed the Memorandum and all such other
information that the Investor considers necessary or appropriate to evaluate the
risks and merits of an investment in the Investor Shares (including without
limitation, the Stock Purchase Agreement, the First Reserve Subscription
Agreement, the Securityholders' Agreement and the Credit Agreement). The
Investor has not distributed the Memorandum or this Investment Agreement or such
information to any person or entity other than the Investor's legal, tax and
accounting advisors, if any.

            (d) OPPORTUNITY TO QUESTION. The Investor has had the opportunity to
question, and has questioned, to the extent the Investor has deemed necessary or
appropriate, representatives of the Company so as to receive answers and verify
information contained in the Memorandum or obtained in the Investor's

the Investor Shares that were in any way inconsistent with the Memorandum or the
other information reviewed by the Investor.

            (f) KNOWLEDGE AND EXPERIENCE. The Investor has such knowledge and
experience in financial, tax and business matters, including without limitation
substantial experience in evaluating and investing in common stock and other
securities (including without limitation the common stock and other securities
of new and speculative companies and companies engaged in oil and gas
exploration and production), so as to enable the Investor to utilize the
information referred to in paragraph (c) of this Section 2.1 and all other
information made available to the Investor in order to evaluate the risks and
merits of an investment in the Investor Shares and to make an informed
investment decision with respect thereto. In addition,

<PAGE>
the Investor has been advised to consult with an attorney regarding legal
matters concerning the Company and to consult with a tax and/or accounting
advisor regarding the tax consequences of investing in the Company and
purchasing the Investor Shares.

            (g) INDEPENDENT DECISION. The Investor is not relying on the Company
or any references to any legal or other opinion in the materials reviewed by the
Investor with respect to the tax considerations of the Investor relating to an
investment in the Investor Shares pursuant to Section 1.1 hereof. The Investor
has relied solely on its own examination and independent investigation of the
Company, the Investor Shares and Securityholders' Agreement in making its
decision to acquire the Investor Shares.

            (h) FINANCIAL CONDITION. The Investor's financial condition and
income are such that (i) the Investor is under no present need to dispose of any
portion of the Investor Shares to satisfy any existing or contemplated
undertaking or indebtedness and (ii) the Investor is able to bear the economic
risk of investment in the Investor Shares, including the risk of losing the
entire investment and the risk of not being able to sell or transfer any of the
Investor Shares for an indefinite period of time. In this regard, the Investor
recognizes that the Securityholders' Agreement contains a prohibition on any
transfer of such Shares for the period described in the Memorandum.

            (i) RESTRICTED SECURITIES. The Investor understands that the
Investor may be required to bear the economic risk of investment in the Investor
Shares for an indefinite period of time because the Investor Shares (i) may not,
without full compliance with the registration and prospectus delivery
requirements of the Securities Act and applicable Blue Sky Laws, be offered,
sold or delivered except in a transaction exempt from, or not subject to, the
registration and prospectus delivery requirements of the Securities Act and
applicable Blue Sky Laws and (ii) are additionally subject to all of the
prohibitions, restrictions and other limitations on transfer set forth in the
Securityholders' Agreement. The Investor understands that the Company has no
obligation to cause or permit the registration of any of the Investor Shares
under the Securities Act or any Blue Sky Laws except as set forth in the
Securityholders' Agreement.

            (j) RESTRICTIONS ON RESALE OR TRANSFER. The Investor will not
transfer or pledge any or all of the Investor Shares in violation of the
Securityholders' Agreement or the Securities Act or any applicable Blue Sky Laws
and in the event that the Investor pledges any of the Investor Shares to a
person or entity other than the Company or another party to the Securityholders'
Agreement (to the extent permitted under the Securityholders' Agreement, the
Securities Act and any applicable Blue Sky

                                        5
<PAGE>
Laws), the Investor will comply with the Securityholders' Agreement in
connection therewith, will advise the pledgee of the transfer restrictions
imposed on the Investor Shares by this Investment Agreement and will use his or
her best efforts to obtain an undertaking from such pledgee not to transfer such
Investor Shares in violation of the Securities Act or applicable Blue Sky Laws.

            (k) RESTRICTIVE LEGEND. The certificates from time to time
evidencing the Investor Shares may, at the Company's sole option, bear a legend
that provides that the Investor Shares have not been registered under the
Securities Act or any applicable Blue Sky Laws and that the Investor Shares may
not be transferred unless the Company is first delivered a legal opinion,
satisfactory to the Company in its sole discretion, to the effect that such
transfer may be made without compliance with the registration and prospectus
delivery requirements of the Securities Act and applicable Blue Sky Laws. Such
legal opinion shall be given by counsel satisfactory to the Company in its sole
discretion, at the Investor's expense. Under the terms of the Securityholders'
Agreement, the certificates representing the Shares are required to bear the
following legend:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
      ANY APPLICABLE STATE SECURITIES LAWS, AND ARE SUBJECT TO THE PROVISIONS

      ENERGY CORPORATION (THE "COMPANY"), FIRST RESERVE FUND VII, LIMITED
      PARTNERSHIP AND THE INDIVIDUALS AND TRUSTS SIGNATORY THERETO, AS SUCH
      AGREEMENT MAY BE AMENDED (AS AMENDED, IF AMENDED, THE "SECURITYHOLDERS'
      AGREEMENT"), A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.
      THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT (AND THE HOLDER OF
      THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE, AGREES THAT SUCH
      SECURITIES MAY NOT AND WILL NOT) BE TRANSFERRED, SOLD, ASSIGNED, PLEDGED,
      HYPOTHECATED OR OTHERWISE DISPOSED OF (1) EXCEPT IN COMPLIANCE WITH THE
      SECURITYHOLDERS' AGREEMENT AND (2) EXCEPT AS OTHERWISE PROVIDED IN THE
      SECURITYHOLDERS' AGREEMENT, UNLESS AND UNTIL SUCH SECURITIES ARE
      REGISTERED UNDER THE SECURITIES ACT

                                        6
<PAGE>
      AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL FOR THE
      HOLDER SATISFACTORY TO THE COMPANY IS OBTAINED TO THE EFFECT THAT SUCH
      REGISTRATION IS NOT REQUIRED. ADDITIONALLY, IF THE HOLDER IS A CITIZEN OR
      RESIDENT OF ANY COUNTRY OTHER THAN THE UNITED STATES, OR THE HOLDER
      DESIRES TO EFFECT ANY SUCH TRANSACTION IN ANY SUCH COUNTRY, THE COMPANY
      MUST BE FURNISHED WITH A SATISFACTORY OPINION OR OTHER ADVICE OF COUNSEL
      FOR THE HOLDER THAT SUCH TRANSACTION WILL NOT VIOLATE THE LAWS OF SUCH
      COUNTRY."

The Investor has read and understands the restrictions on transfer set forth in
such legend and in the Securityholders' Agreement and agrees to comply with all
such restrictions.

            (l) FURTHER ACTIONS. The Investor shall, at the Company's expense,
take all further actions necessary to facilitate the issuance of the Investor
Shares to the Investor under an appropriate exemption from registration under
the Securities Act and applicable Blue Sky Laws, including without limitation
providing the Company with such information as the Company may require to
complete a Form D and any related or similar forms or applications required
under the Securities Act or applicable Blue Sky Laws.

            (m) AUTHORIZATION; LEGAL COMPETENCE. The Investor has full power and
authority to execute this Investment Agreement and to invest in the Investor
Shares, and this Investment Agreement constitutes the valid and legally binding
obligation of such Investor, enforceable against such Investor in accordance
with its terms.

            (n) NO "MERIT REVIEW". The Investor understands that no
commissioners of securities or equivalent officials of any state have made any
finding or determination relating to the fairness of an investment in the Shares
and that no such person has recommended or endorsed the Shares.

            The provisions hereof shall inure to the benefit of the Company, its
successors and assigns and shall be binding upon the Investor, his or her legal
representatives, successors and assigns.

                             PROMISSORY NOTE


$87,000.00                                      Houston, Texas
                                                February __, 1997


            FOR VALUE RECEIVED, the undersigned, Herbert A. Newhouse (the
"Executive"), hereby unconditionally promises to pay to the order of Domain
Energy Corporation, a Delaware corporation (the "Company") at its offices, in
lawful money of the United States of America, the principal amount of
EIGHTY-SEVEN THOUSAND DOLLARS ($87,000.00). The principal amount shall be paid
on the earliest to occur of (i) if there has occurred a Qualified Public
Offering (as such term is defined in the Securityholders Agreement (the
"Securityholders Agreement") dated as of December 31, 1996 by and among the
Company, the Executive and the individuals and trusts party thereto), the
Executive's termination of employment by the Company for Cause or without Good
Reason by the Executive, (ii) if there has occurred a Qualified Public Offering,
one year after the Executive's termination of employment without Cause by the
Company or with Good Reason by the Executive, (iii) the disposition of any of
the Investor Shares (as such term is defined in the Management Investor
Subscription Agreement referred to below) by the Executive, provided, that the
Executive shall be required only to pay that amount of the principal amount
which is equal to the proceeds received from any such disposition (with any
outstanding unpaid principal remaining subject to this sentence) and (iv)
December 31, 2003 (the "Maturity Date"). The Executive further agrees to pay
interest in like money at such office on the unpaid principal amount hereof from
time to time outstanding at an interest rate equal to 8% on (x) June 30 and
December 31 of each year (each such date, a "Interim Interest Payment Date"),
(y) the Maturity Date and (z) with respect to the amount of any optional
repayment, on the date of any such optional repayment; provided, however, that
with respect to interest payments due pursuant to clause (x) above, on written
notice given to Company not less than 15 days prior to any Interim Interest
Payment Date the Executive may elect to satisfy his or her interest payment
obligations by increasing the principal amount of this note by the amount of
such interest due. Such an election shall apply to all interest payments due on
all future Interim Interest Payment Dates until revoked. "Cause" shall mean,
except as otherwise provided in an employment agreement between the Company and
the Executive, (i) the commission of an act of fraud or embezzlement or other
willful misconduct against the Company or its affiliates (including the
unauthorized disclosure of confidential or proprietary information of the
Company or any of its subsidiaries

<PAGE>
which results in material financial loss to the Company or any of its
affiliates), (ii) the commission by the Executive of a felony, or (iii) the
willful failure to render services to the Company or any of its affiliates in
accordance with his or her employment which failure amounts to a material
neglect of duties to the Company or any of its affiliates; and "Good Reason"
shall mean, except as otherwise provided in an employment agreement between the
Company and the Executive, (x) any material reduction by the Company of the
Executive's authority, duties or responsibilities (except in connection with the
termination of the Executive's employment for Cause, as a result of Permanent
Disability, as such term is defined below, or as a result of the Executive's
death or Retirement, as such term is defined below), (y) any reduction by the
Company in the Executive's base salary or (z) the Company's moving the
Executive's place of employment outside the Houston, Texas metropolitan area.
Notwithstanding the immediately preceding sentence, the definitions in any
employment agreement in effect on the date hereof between the Company and the
Executive of "Cause" and "Good Reason" shall supersede and replace the
definitions of "Cause" and "Good Reason" in the immediately preceding sentence
and shall be deemed incorporated by reference in this Note in their entirety.

            The following shall constitute "Events of Default" under the terms
of this Note:

                  (i) default in payment when due and payable, upon acceleration
            or otherwise, of principal of this Note;

                  (ii) default for five (5) days or more in the payment when due
            of interest on the Note.

            "Default" means any event that is or with the passage of time or the
giving of notice or both would be an Event of Default.

            For purposes of this Note, the Executive shall be deemed to have a
"Permanent Disability" if the Executive is unable to engage in the activities
required by the Executive's job by reason of any medically determined physical
or mental impairment which can be expected to result in death or which can be
expected to last for a continuous period of not less than 12 months.

            For purposes of this Note, "Retirement" shall mean the voluntary
termination of employment by the Executive at age 62 or older (or such other age
as may be approved by the Board of Directors of the Company) after having been
employed by the Company for at least three years after the date hereof.

                                        2

            This Note is subject to optional prepayment in whole or in part at
any time. Reference is hereby made to the Pledge Agreement for a description of
the properties and assets in which a security interest has been granted.

            Upon the occurrence of any one or more of the Events of Default, all
amounts then remaining unpaid on this Note shall become, or may be declared to
be, immediately due and payable by the Company.

            All parties now and hereafter liable with respect to this Note,
whether maker, principal, surety, guarantor, endorser or otherwise, hereby waive
presentment, demand, protest and all other notices of any kind.

            Capitalized terms not otherwise defined herein shall have the
meanings assigned to such terms in the Management Investor Subscription
Agreement dated as of February __, 1997 between the Company and the Executive
(the "Management Investor Subscription Agreement").

            THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

of law, including, without limitation, Section 9-504(l)(c) of the Code, need the

                                                February 21, 1997

            FOR VALUE RECEIVED, the undersigned, Michael V. Ronca (the
"Executive"), hereby unconditionally promises to pay to the order of Domain
Energy Corporation, a Delaware corporation (the "Company") at its offices, in
lawful money of the United States of America, the principal amount of TWO
HUNDRED FORTY-NINE THOUSAND, TWO HUNDRED DOLLARS ($249,200.00). The principal
amount shall be paid on the earliest to occur of (i) if there has occurred a
Qualified Public Offering (as such term is defined in the Securityholders
Agreement (the "Securityholders Agreement") dated as of December 31, 1996 by and
among the Company, the Executive and the individuals and trusts party thereto),
the Executive's termination of employment by the Company for Cause or without
Good Reason by the Executive, (ii) if there has occurred a Qualified Public
Offering, one year after the Executive's termination of employment without Cause
by the Company or with Good Reason by the Executive, (iii) the disposition of
any of the Investor Shares (as such term is defined in the Management Investor
Subscription Agreement referred to below) by the Executive, provided, that the
Executive shall be required only to pay that amount of the principal amount
which is equal to the proceeds received from any such disposition (with any
outstanding unpaid principal remaining subject to this sentence) and (iv)
December 31, 2003 (the "Maturity Date"). The Executive further agrees to pay
interest in like money at such office on the unpaid principal amount hereof from
time to time outstanding at an interest rate equal to 8% per annum on (x) June
30 and December 31 of each year (each such date, a "Interim Interest Payment
Date"), (y) the Maturity Date and (z) with respect to the amount of any optional
repayment, on the date of any such optional repayment; provided, however, that
with respect to interest payments due pursuant to clause (x) above, on written
notice given to Company not less than 15 days prior to any Interim Interest
Payment Date the Executive may elect to satisfy his or her interest payment
obligations by increasing the principal amount of this note by the amount of
such interest due. Such an election shall apply to all interest payments due on
all future Interim Interest Payment Dates until revoked. "Cause" shall mean,
except as otherwise provided in an employment agreement between the Company and
the Executive, (i) the commission of an act of fraud or embezzlement or other
willful misconduct against the Company or its affiliates (including the
unauthorized disclosure of confidential or proprietary information of the
Company or any of its subsidiaries which results in material
<PAGE>
financial loss to the Company or any of its affiliates), (ii) the commission by
the Executive of a felony, or (iii) the willful failure to render services to
the Company or any of its affiliates in accordance with his or her employment
which failure amounts to a material neglect of duties to the Company or any of
its affiliates; and "Good Reason" shall mean, except as otherwise provided in an
employment agreement between the Company and the Executive, (x) any material
reduction by the Company of the Executive's authority, duties or
responsibilities (except in connection with the termination of the Executive's
employment for Cause, as a result of Permanent Disability, as such term is
defined below, or as a result of the Executive's death or Retirement, as such
term is defined below), (y) any reduction by the Company in the Executive's base
salary or (z) the Company's moving the Executive's place of employment outside
the Houston, Texas metropolitan area. Notwithstanding the immediately preceding
sentence, the definitions in any employment agreement in effect on the date
hereof between the Company and the Executive of "Cause" and "Good Reason" shall
supersede and replace the definitions of "Cause" and "Good Reason" in the
immediately preceding sentence and shall be deemed incorporated by reference in
this Note in their entirety.

            The following shall constitute "Events of Default" under the terms
of this Note:

                  (i) default in payment when due and payable, upon acceleration
            or otherwise, of principal of this Note;

                  (ii) default for five (5) days or more in the payment when due
            of interest on the Note.

            "Default" means any event that is or with the passage of time or the
giving of notice or both would be an Event of Default.

            For purposes of this Note, the Executive shall be deemed to have a
"Permanent Disability" if the Executive is unable to engage in the activities
required by the Executive's job by reason of any medically determined physical
or mental impairment which can be expected to result in death or which can be
expected to last for a continuous period of not less than 12 months.

            For purposes of this Note, "Retirement" shall mean the voluntary
termination of employment by the Executive at age 62 or older (or such other age
as may be approved by the Board of Directors of the Company) after having been
employed by the Company for at least three years after the date hereof.

be, immediately due and payable by the Company.

            All parties now and hereafter liable with respect to this Note,

demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or
upon the Executive or any other Person (all and each of which demands, defenses,
advertisements and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, assign, give option or options to
purchase or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or

board or office of Company or elsewhere upon such terms and conditions as it may
deem advisable and at such prices as it may deem best, for cash or on credit or
for future delivery without assumption of any credit risk. The Company shall
have the right upon any such public sale or sales, and, to the extent permitted
by law, upon any such private sale or sales, to purchase the whole or any part
of the Collateral so sold, free of any right or equity of redemption in the
Executive, which right or equity is hereby waived or released. The Company shall
apply any Proceeds from time to time held by it and the net proceeds of any such
collection, recovery, receipt, appropriation, realization or sale, after

thereof or incidental to the care or safekeeping of any of the Collateral or in
any way relating to the Collateral or the rights of the Company hereunder,
including, without limitation, reasonable attorneys' fees and disbursements of
counsel to the Company, to the payment in whole or in part of the Obligations,

Company account for the surplus, if any, to the Executive. To the extent
permitted by applicable law, the Executive waives all claims, damages and
demands it may acquire against the Company arising out of the exercise by it of
any rights hereunder. If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition. The
Executive shall remain liable for any deficiency if the proceeds of any sale or
other disposition of Collateral are insufficient to pay the Obligations and the
fees and disbursements of any attorneys employed by the Company to collect such
deficiency.

      8. EXECUTION OF FINANCING STATEMENTS. Pursuant to Section 9-402 of the
Code, the Executive authorizes the Company to file financing statements with
respect 
                                  5
<PAGE>

such filing offices as the Company reasonably determines appropriate to perfect
the security interests of the Company under this Agreement. A carbon,
photographic or other reproduction of this Agreement shall be sufficient as a
financing statement for filing in any jurisdiction.

the Executive to be effective shall be in writing (or by telex, facsimile or
similar electronic transfer confirmed in writing) and shall be deemed to have
been duly given or made (1) when delivered by hand or (2) if given by mail, when

for notices by notice in the manner provided in this Section 9.

unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      11. AMENDMENTS IN WRITING; NO WAIVER; CUMULATIVE REMEDIES. (a) None of the
terms or provisions of this Agreement may be waived, amended, supplemented or
otherwise modified except by a written instrument executed by the Executive and
the Company, PROVIDED that any provision of this Agreement may be waived by the
Company in a letter or agreement executed by the Company or by telex or
facsimile transmission from the Company.

            (b) The Company shall not by any act (except by a written instrument
pursuant to paragraph 11(a) hereof), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default ot Event of Default or in any breach of any of the terms and conditions
hereof. No failure to exercise, nor any delay in exercising, on the part of the
Company, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Company of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Company would otherwise have on any future occasion.

            (c) The rights and remedies herein provided are cumulative, may be

                              EMPLOYMENT AGREEMENT

               AGREEMENT, made December 31, 1996, by and between
Domain Energy Corporation, a Delaware corporation (the "Company")
and Michael V. Ronca ("Executive").

                                    RECITALS

               In order to induce Executive to serve as the President and Chief
Executive Officer of the Company, the Company desires to provide Executive with
compensation and other benefits on the terms and conditions set forth in this
Agreement.
               Executive is willing to accept such employment and perform
services for the Company, on the terms and conditions hereinafter set forth.
               It is therefore hereby agreed by and between the parties as
follows:
               1.  EMPLOYMENT.
               1.1 Subject to the terms and conditions of this Agreement, the
Company hereby employs Executive during the term hereof as its President and
Chief Executive Officer. In his capacity as the President and Chief Executive
Officer of the Company, Executive shall report to the Board of Directors of the
Company (the "Board") and shall have the customary powers, responsibilities and
authorities of chief executive officers of corporations of the size, type and
nature of the Company, as it exists from time to time, as are assigned by the
Board.
               1.2  Subject to the terms and conditions of this
Agreement, Executive hereby accepts employment as the President
<PAGE>
and Chief Executive Officer of the Company and agrees to devote his full working
time and efforts, to the best of his ability, experience and talent, to the
performance of services, duties and responsibilities in connection therewith.
Executive shall perform such duties and exercise such powers, commensurate with
his position, as the President and Chief Executive Officer of the Company, as
the Board shall from time to time delegate to him on such terms and conditions
and subject to such restrictions as such Board may reasonably from time to time
impose. Executive also agrees to serve, if elected, as a member of the Board.
               1.3 Nothing in this Agreement shall preclude Executive from
engaging, so long as, in the reasonable determination of such Board, such
activities do not interfere with his duties and responsibilities hereunder, in
charitable and community affairs, from managing any passive investment made by
him in equity securities or other assets (provided that no such investment may
exceed 5% of the equity of any entity, without the prior approval of such Board
of Directors and Executive shall give the Board of Directors prior written
notice of any investment in an entity that is not publicly traded) or from
serving, subject to the prior approval of such Board of Directors, as a member
of boards of directors or as a trustee of any other corporation, association or
entity. For purposes of the preceding sentence, any approval of the Board
required therein shall not be unreasonably withheld.
               2.  TERM OF EMPLOYMENT.  Executive's term of employment
under this Agreement shall commence as of the date hereof and,
<PAGE>
subject to the terms hereof, shall terminate on the earlier of (i) December 31,
1999 (the "Termination Date") or (ii) termination of Executive's employment
pursuant to this Agreement; PROVIDED, HOWEVER, that any termination of
employment by Executive (other than for death, Permanent Disability or Good
Reason) may only be made upon 60 days prior written notice to the Company and
any termination of employment by Executive for Good Reason may only be made upon
30 days prior written notice to the Company.
               3.  COMPENSATION.
               3.1 SALARY. The Company shall pay Executive a base salary ("Base
Salary") at the rate of $180,000 per annum for the period commencing on the
beginning of Executive's term of employment hereunder and ending on the
Termination Date. Base Salary shall be payable in accordance with the ordinary
payroll practices of the Company. Any increase in Base Salary shall be in the
discretion of the Board and, as so increased, shall constitute "Base Salary"
hereunder.
               3.2 ANNUAL BONUS. In addition to his Base Salary, Executive shall
be paid an annual cash bonus (the "Bonus") during the term of his employment
hereunder with a target amount equal to 50% of Base Salary (the "Target Bonus")
and a maximum amount equal to 90% of Base Salary based on performance criteria
determined by the Company's Board of Directors in its sole discretion.
               3.3  COMPENSATION PLANS AND PROGRAMS.  Executive shall
be entitled to participate in any compensation plan or program
<PAGE>
maintained by the Company in which other senior executives of the Company
participate on terms comparable to those applicable to such other senior
executives.
               4.  EMPLOYEE BENEFITS.
               4.1  EMPLOYEE BENEFIT PROGRAMS, PLANS AND PRACTICES.  The
                    ----------------------------------------------
Company shall provide Executive during the term of his employment
hereunder with coverage under all employee pension and welfare
benefit programs, plans and practices (commensurate with his
positions in the Company and to the extent permitted under any
employee benefit plan) in accordance with the terms thereof, which
the Company makes available to its senior executives (including,
without limitation, participation in health, dental, group life,
disability, retirement and all other plans and fringe benefits to
the extent generally provided to such senior executives).
               4.2 VACATION AND FRINGE BENEFITS. Executive shall be entitled to
no less than twenty-five (25) business days paid vacation in each calendar year,
which shall be taken at such times as are consistent with Executive's
responsibilities hereunder. Such vacation time shall accrue at a rate of 2.08
vacation days for each calendar month worked. Unless otherwise approved by the
Board, any vacation days not taken in any calendar year shall be forfeited
without payment therefor. In addition, Executive shall be entitled to the
perquisites and other fringe benefits commensurate with his position with the
Company, which the parties agree shall be $20,000 annually (excluding such paid
vacation). Such annual amount shall be paid to the Executive on
<PAGE>
the same periodic basis as his Base Salary, and Executive shall have the right
to determine the utilization and apportionment thereof among such perquisites
and other fringe benefits. The Company shall furnish Executive with a private
office and a private secretary and all other reasonable assistance and
accommodations.
               5. EXPENSES. Executive is authorized to incur reasonable expenses
in carrying out his duties and responsibilities under this Agreement and
promoting the business of the Company, including, without limitation, expenses
for travel, lodgings, entertainment and similar items related to such duties and
responsibilities. The Company will reimburse Executive for all such expenses
upon presentation by Executive from time to time of appropriately itemized and
approved (consistent with the Company's policy) accounts of such expenditures.
               6.  TERMINATION OF EMPLOYMENT.
               6.1 TERMINATION NOT FOR CAUSE OR TERMINATION FOR GOOD REASON. (a)
Subject to the terms and conditions of this Agreement, the Company may terminate
Executive's employment at any time for any reason. If Executive's employment is
terminated by the Company other than for Cause (as defined in Section 6.4(b)
hereof) or other than as a result of Executive's death, Retirement (as defined
below in this Section 6.1(a)) or Permanent Disability (as defined in Section 6.2
hereof) or if Executive terminates his employment for Good Reason (as defined in
Section 6.1 (c) hereof) prior to the Termination Date, Executive shall
<PAGE>
receive all such payments, if any, under applicable compensation and employee
benefit plans or programs, including but not limited to those referred to in
Section 3.3 hereof, to which he is entitled pursuant to the terms of such plans
or programs. In addition, Executive shall receive a lump sum cash payment (the
"Termination Amount") in lieu of any Bonus in respect of all or any portion of
the fiscal year in which such termination occurs and any other cash compensation
(other than the Vacation Payment and the Compensation Payment referred to
below). The Termination Amount shall consist of the greater of (i) an amount
equal to the Executive's Base Salary at its then current annual rate plus the
amount of Executive's Target Bonus for the entire year in which his termination
occurs (irrespective of whether the performance criteria have been met) or (ii)
the aggregate amount of Base Salary which Executive would have received for the
remaining term of this Agreement. In addition, Executive shall receive a cash
lump sum payment in respect of accrued but unused vacation days (the "Vacation
Payment") and all compensation earned but not yet paid (including any deferred
Bonus payments) (the "Compensation Payment"). "Retirement" means the termination
of Executive's employment with the Company and all of its affiliates as a result
of his reaching a retirement age (not less than 62 years of age) established by
the Board for his retirement.
               (b) The Termination Amount, the Vacation Payment and the
Compensation Payment shall be paid by the Company to Executive within 30 days
after the termination of Executive's employment by check payable to the order of
Executive or by wire
<PAGE>
transfer to an account specified by Executive. Payments or amounts to which
Executive is entitled under applicable compensation and employee benefit plans
or programs will be paid to Executive pursuant to the terms of such plans or
programs.
               (c) For purposes of this Agreement, "Good Reason" shall mean any
of the following (without Executive's express prior written consent):
               (i) any removal of Executive as the President and Chief Executive
        Officer of the Company or any material reduction by the Company of
        Executive's authority, duties or responsibilities (except in connection
        with the termination of Executive's employment for Cause, as a result of
        Permanent Disability, or as a result of Executive's death or
        Retirement);

            (ii) any reduction by the Company in Executive's Base Salary, other
        than a reduction which is part of a uniformly applied general salary
        reduction program affecting senior executives of the Company;

               (iii)  the Company's moving Executive's place of
        employment outside the Houston, Texas metropolitan area; or

               (iv) Executive's election to terminate his employment for any
        reason within 30 calendar days following a Change of Control (as defined
        in the Non-Qualified Stock Option Agreement attached hereto as Exhibit A
        (the "Option Agreement")).

               6.2 PERMANENT DISABILITY. If the Executive becomes totally and
permanently disabled (as defined in the Company's Long-Term Disability Benefit
Plan applicable to senior executive officers as in effect on the date hereof)
("Permanent Disability"), the Company or Executive may terminate Executive's
employment on written notice thereof, and in any such case Executive shall
receive or commence receiving:
               (i) as soon as possible under the terms thereof, all amounts
        payable pursuant to the terms of any disability insurance policy or
        similar arrangement which the Company maintains during the term hereof;
<PAGE>
            (ii) within 30 days after the giving or receipt of such notice by
        the Company, as the case may be, the Target Bonus in respect of the
        fiscal year in which his termination occurs (irrespective of whether the
        performance criteria have been met), prorated by a fraction, the
        numerator of which is the number of days of the fiscal year until
        termination and the denominator of which is 365;

           (iii) within 30 days after the giving or receipt of such notice by
        the Company, as the case may be, the Vacation Payment and the
        Compensation Payment; and

            (iv) as soon as possible under the terms thereof, all such payments
        under applicable plans or programs, including but not limited to those
        referred to in Sections 3.3 and 4.1 hereof, to which he is entitled
        pursuant to the terms of such plans or programs, in accordance with
        their terms.

               6.3 DEATH. In the event of Executive's death during the term of
his employment hereunder, Executive's estate or designated beneficiaries shall
receive or commence receiving:
               (i) within 30 days after the Company knows of Executive's death,
        the Target Bonus in respect of the fiscal year in which his death occurs
        (irrespective of whether the performance criteria have been met),
        prorated by a fraction, the numerator of which is the number of days of
        the fiscal year until his death and the denominator of which is 365;

           (ii)  within 30 days after the Company knows of
        Executive's death, the Vacation Payment and the
        Compensation Payment; and

            (iii) as soon as possible under the terms thereof, all such payments
        under applicable plans or programs, including but not limited to those
        referred to in Sections 3.3 and 4.1 hereof, to which Executive's estate
        or designated beneficiaries are entitled pursuant to the terms of such
        plans or programs, in accordance with their terms.

               6.4  VOLUNTARY TERMINATION BY EXECUTIVE; DISCHARGE FOR
CAUSE.  (a)  The Company shall have the right to terminate the
employment of Executive for Cause.  In the event that Executive's
employment is terminated by the Company for Cause, as hereinafter
defined, or by Executive other than for Good Reason or other than
<PAGE>
as a result of the Executive's Permanent Disability, Retirement or death,
Executive shall only be entitled to receive, within 30 days after such
termination, the Compensation Payment and the Vacation Payment and any other
then-vested benefits under any compensation or employee benefit plans or
programs to which he is entitled pursuant to the terms of such plans or
programs. Executive shall not be entitled, among other things, to the payment of
any Bonus in respect of all or any portion of the fiscal year in which such
termination occurs. After the termination of Executive's employment under this
Section 6.4, the obligations of the Company under this Agreement to make any
further payments, or provide any benefits other than those specified herein, to
Executive shall thereupon cease and terminate.
               (b) As used herein, the term "Cause" shall be limited to (i)
Executive's commission of any act of fraud or embezzlement against the Company
or any of its affiliates, irregardless of whether such act results in material
financial loss to the Company or any of its affiliates, or other willful
malfeasance or willful misconduct by Executive in connection with his employment
that results in material financial loss to the Company or any of its affiliates,
(ii) continuing refusal by Executive to perform his duties hereunder or any
lawful direction of the Board as required under Section 1.2, after written
notice of any such refusal to perform such duties or direction was given to
Executive by the Board and Executive has been given a 30-day cure period after
receipt of such notice to take reasonable corrective
<PAGE>
action, (iii) any material breach of the provisions of Section 13 of this
Agreement by Executive or any other material breach of this Agreement by
Executive after written notice of any such breach was given to Executive by the
Board and Executive has been given a 30-day cure period after receipt of such
notice to take reasonable corrective action or (iv) the conviction of Executive
for any felony. Termination of Executive pursuant to Section 6.4 shall be made
by delivery to Executive of a copy of a resolution duly adopted by the
affirmative vote of not less than a majority of the entire Board at a meeting of
the Board called and held for such purpose (after 30 days prior written notice
(which may include the 30 day period referred to in (ii) above) to Executive and
reasonable opportunity for Executive to be heard before the Board prior to such
vote), finding that in the reasonable judgment of such Board, Executive was
guilty of conduct set forth in any of clauses (i) through (iv) above and
specifying the particulars thereof.
               7. STOCK ARRANGEMENTS. Executive and the Company shall enter into
the Common Stock Management Investor Subscription Agreement attached hereto as
Exhibit B (the "Subscription Agreement"). In addition, on the date of the
purchase of common stock under the Subscription Agreement, the Company shall
issue to the Executive an option to purchase up to 450 shares of the Company's
Common Stock, par value $.01 per share, pursuant to the Option Agreement.
                8.  MITIGATION OF DAMAGES.  Executive shall not be
required to mitigate any damages or the amount of any payment
<PAGE>
provided for under this Agreement by seeking other employment or otherwise after
the termination of his employment hereunder, and any amounts earned by
Executive, whether from self-employment, as a common-law employee or otherwise,
shall not reduce the amount of any Termination Amount or other payments or
amounts otherwise payable to him.
               9.     NOTICES.  All notices or communications hereunder

intestate succession) or by the Company, except that the Company may assign this
Agreement to any successor (whether by merger, purchase or otherwise) to all or
substantially all of the stock, assets or businesses of the Company, if such
successor expressly agrees to assume the obligations of the Company hereunder.
<PAGE>
               12.  AMENDMENT.  This Agreement may only be amended by
written agreement of the parties hereto.
               13. NONDISCLOSURE OF CONFIDENTIAL INFORMATION; NON- COMPETITION.
(a) Executive shall not, without the prior written consent of the Company, use,
divulge, disclose or make accessible to any other person, firm, partnership,
corporation or other entity any Confidential Information pertaining to the
business of the Company or any of its affiliates, except (i) while employed by
the Company, in the business of and for the benefit of the Company, or (ii) when
required to do so by a court of competent jurisdiction, by any governmental
agency having supervisory authority over the business of the Company, or by any
administrative body or legislative body (including a committee thereof) with
jurisdiction to order Executive to divulge, disclose or make accessible such
information. For purposes of this Section 13(a), "Confidential Information"
shall mean non-public information concerning the financial data, strategic
business plans, product development (or other proprietary product data),
customer lists, marketing plans and other non-public, proprietary and
confidential information of the Company, First Reserve Corporation or their
respective affiliates (the "Restricted Group") or customers, that, in any case,
is not otherwise available to the public (other than by Executive's breach of
the terms hereof).
               (b) During the period of his employment hereunder and for six (6)
months thereafter, Executive agrees that, without the prior written consent of
the Company, (A) he will not, directly
<PAGE>
or indirectly, either as principal, manager, agent, consultant, officer,
stockholder, partner, investor, lender or employee or in any other capacity,
carry on, be engaged in or have any financial interest in, any business or
entity which is in competition with the business of any member of the Restricted
Group engaged in the oil and gas exploration and production business and (B) he
shall not, on his own behalf or on behalf of any person, firm or company,
directly or indirectly, solicit or offer employment to any person who has been
employed by any member of the Restricted Group engaged in the oil and gas
exploration and production business at any time during the 12 months immediately
preceding such solicitation.
               (c) For purposes of this Section 13, a business shall be deemed
to be in competition with a member of the Restricted Group engaged in the oil
and gas exploration and production business if it is also principally engaged in
the oil and gas exploration and production business within the same geographic
area in which such member of the Restricted Group is so engaged. Nothing in this
Section 13 shall be construed so as to preclude Executive from investing in any
publicly or privately held company, provided Executive's beneficial ownership of
any class of such company's securities does not exceed 5% of the outstanding
securities of such class.
               (d) Executive and the Company agree that this covenant not to
compete is a reasonable covenant under the circumstances, and further agree that
if in the opinion of any court of competent jurisdiction such restraint is not
reasonable in any
<PAGE>
respect, such court shall have the right, power and authority to excise or
modify such provision or provisions of this covenant as to the court shall
appear not reasonable and to enforce the remainder of the covenant as so
amended. Executive agrees that any breach of the covenants contained in this
Section 13 would irreparably injure the Company. Accordingly, Executive agrees
that the Company may, in addition to pursuing any other remedies it may have in
law or in equity, cease making any payments otherwise required by this Agreement
(until any such breach is cured) and obtain an injunction against Executive from
any court having jurisdiction over the matter restraining any further violation
of this Agreement by Executive.
               14. BENEFICIARIES; REFERENCES. Executive shall be entitled to
select (and change, to the extent permitted under any applicable law) a
beneficiary or beneficiaries to receive any compensation or benefit payable
hereunder following Executive's death, and may change such election, in either
case by giving the Company written notice thereof. In the event of Executive's
death or a judicial determination of his incompetence, reference in this
Agreement to Executive shall be deemed, where appropriate, to refer to his
beneficiary, estate or other legal representative. Any reference to the
masculine gender in this Agreement shall include, where appropriate, the
feminine.
               15.  SURVIVORSHIP.  The respective rights and
obligations of the parties hereunder shall survive any
termination of this Agreement to the extent necessary to the
intended preservation of such rights and obligations.  The
<PAGE>
provisions of this Section 15 are in addition to the survivorship provisions of
any other section of this Agreement.
               16.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED,
INTERPRETED AND GOVERNED IN ACCORDANCE WITH THE LAWS OF THE STATE
OF DELAWARE, WITHOUT REFERENCE TO RULES RELATING TO CONFLICTS OF
LAW.
               17. EFFECT ON PRIOR AGREEMENTS. This Agreement contains the
entire understanding between the parties hereto with respect to the subject
matter hereof and supersedes in all respects any prior or other agreement or
understanding between the Company or any affiliate of the Company and Executive
with respect to such subject matter, other than the Option Agreement.
               18.    WITHHOLDING.  The Company shall be entitled to
withhold from payment any amount of withholding required by law.
               19.  COUNTERPARTS.  This Agreement may be executed in
two or more counterparts, each of which will be deemed an
original.

            CREDIT AGREEMENT dated as of December 31, 1996, between:

            (1) DOMAIN ENERGY CORPORATION, a corporation duly organized and
      validly existing under the laws of the State of Delaware (the "COMPANY");

            (2) each of the Subsidiaries of the Company identified under the
      caption "SUBSIDIARY GUARANTORS" on the signature pages hereto
      (individually, a "SUBSIDIARY GUARANTOR" and, collectively, the "SUBSIDIARY
      GUARANTORS" and, together with the Company, the "OBLIGORS");

            (3) each of the lenders that is a signatory hereto identified under
      the caption "LENDERS" on the signature pages hereto and each lender that
      becomes a "Lender" after the date hereof pursuant to Section 12.06(b)
      hereof (individually, a "LENDER" and, collectively, the "LENDERS"); and

            (4) THE CHASE MANHATTAN BANK, a New York bank, as agent for the
      Lenders (in such capacity, together with its successors in such capacity,
      the "ADMINISTRATIVE AGENT").

            Each of the Obligors has requested the Lenders to make loans to the
Company in an aggregate principal amount not exceeding $65,000,000 at any one
time outstanding to provide financing for the Acquisition (as hereinafter
defined), to provide working capital and for other general corporate purposes of
the Company and each of its Subsidiaries. The Company and the Subsidiary
Guarantors are engaged as an integrated group in the O&G Business (as
hereinafter defined) and in related businesses, and in furnishing the required
supplies, services, equipment, credit and other facilities for such integrated
operation. The integrated operation requires financing on such a basis that
credit supplied to the Company be made available from time to time to the
Subsidiary Guarantors, as required for the continued successful operation of the
Obligors, separately, and the integrated operation as a whole.

            To induce the Lenders to make such loans, the Obligors, the Lenders
and the Administrative Agent propose to enter into this Agreement pursuant to
which the Lenders will make loans to the Company, and each Subsidiary Guarantor
will guarantee the loans so made to the Company and each of the Obligors will
agree to execute and deliver mortgages and security agreements providing for
security interests and liens to be granted by the Obligors on at least 80% of
their O&G Properties given value in determining the Borrowing Base and
substantially all of the balance of their respective properties as collateral
security for the obligations of the Obligors to the Lenders and the
Administrative Agent hereunder. Each of the Obligors expects to derive benefit,
directly or indirectly, from the loans so made to the Company, both in its
separate capacity and as a member of the integrated group, since
<PAGE>
                                      -2-

the successful operation of each of the Obligors is dependent on the continued
successful performance of the functions of the integrated group as a whole.

            Accordingly, the parties hereto agree as follows:

            Section 1.  DEFINITIONS AND ACCOUNTING MATTERS.

through ownership of securities or partnership or other ownership interests, by
contract or otherwise), PROVIDED that, in any event, any Person that owns
directly or indirectly securities having 5% or more of the voting power for the

provide or refer to the law of the state where such Lender is located), then
such federal laws shall to such extent govern as to the rate of interest which
such Lender is allowed to contract for, take, reserve, charge or receive under
its Note and this Agreement.

an Unrestricted Subsidiary (as designated in Schedule III hereto) to be a
Restricted Subsidiary; provided that the Company may, without such approval,
designate (by notice to the Administrative Agent which shall promptly notify the
Lenders) a corporation or other entity that is formed or acquired as a direct or
indirect Subsidiary of the Company after the date hereof (no part of the
business or assets of which was owned by the Company or a Restricted Subsidiary
prior to the date of such formation or acquisition) to be an Unrestricted
Subsidiary on or prior to the date of such formation or acquisition if, after
giving effect thereto, no Default shall have occurred and be continuing.

            Section 2.  COMMITMENTS, LOANS, NOTES AND PREPAYMENTS.

            2.01 LOANS. Each Lender severally agrees, on the terms and
conditions of this Agreement, to make loans to the Company in Dollars during the
period from and including the Closing Date to but not including the Commitment
Termination Date in an 
<PAGE>
                                      -28-

aggregate principal amount at any one time outstanding up to but not exceeding
the amount of the Commitment of such Lender as in effect from time to time.
Subject to the terms and conditions of this Agreement, during such period the
Company may borrow, repay and reborrow the amount of the Commitments by means of
ABR Loans and Eurodollar Loans and may Convert Loans of one Type into Loans of
another Type (as provided in Section 2.08 hereof) or Continue Loans of one Type
as Loans of the same Type (as provided in Section 2.08 hereof); PROVIDED that no
more than six separate Interest Periods in respect of Eurodollar Loans from each
Lender may be outstanding at any one time.

            2.02 BORROWINGS. The Company shall give the Administrative Agent
notice of each borrowing hereunder as provided in Section 4.05 hereof. Not later
than 1:00 p.m. New York time on the date specified for each borrowing hereunder,
each Lender shall make available the amount of the Loan or Loans to be made by
it on such date to the Administrative Agent, at an account in New York, New York
specified by the Administrative Agent, in immediately available funds, for
account of the Company. The amount 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 Chase in
New York, New York.

            2.03  CHANGES OF COMMITMENTS.

            (a) The aggregate amount of the Commitments shall be automatically
reduced to zero on the Commitment Termination Date.

            (b) The Company shall have the right at any time or from time to
time (i) so long as no Loans are outstanding, to terminate the Commitments and
(ii) to reduce the aggregate unused amount of the Commitments; PROVIDED that (x)
the Company shall give notice of each such termination or reduction as provided
in Section 4.05 hereof and (y) each partial reduction shall be in an aggregate
amount at least equal to $5,000,000 (or a larger multiple of $1,000,000).

            (c) The Commitments once terminated or reduced may not be
reinstated.

            2.04 COMMITMENT FEE. The Company shall pay to the Administrative
Agent for account of each Lender a commitment fee on the daily average unused
amount of such Lender's Commitment, for the period from and including the date
hereof to but not including the earlier of the date such Commitment is
terminated and the Commitment Termination Date, at a rate per annum equal to the
Applicable Commitment Fee Rate as in effect from 
<PAGE>
                                      -29-

time to time. Accrued commitment fee shall be payable on each Quarterly Date and
on the earlier of the date the Commitments are terminated and the Commitment
Termination Date.

            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.

            2.06 SEVERAL OBLIGATIONS; REMEDIES INDEPENDENT. The failure of any
Lender to make any Loan to be made by it on the date specified therefor shall
not relieve any other Lender of its obligation to make its Loan on such date,
but neither any Lender nor the Administrative Agent shall be responsible for the
failure of any other Lender to make a Loan to be made by such other Lender, and
(except as otherwise provided in Section 4.06 hereof) no Lender shall have any
obligation to the Administrative Agent or any other Lender for the failure by
such Lender to make any Loan required to be made by such Lender. The amounts
payable by the Company at any time hereunder and under the Notes to each Lender
shall be a separate and independent debt and each Lender shall be entitled to
protect and enforce its rights arising out of this Agreement and the Notes, and
it shall not be necessary for any other Lender or the Administrative Agent to
consent to, or be joined as an additional party in, any proceedings for such
purposes.

            2.07  NOTES.

            (a) The Loans made by each Lender shall be evidenced by a single
promissory note of the Company substantially in the form of Exhibit A hereto,
dated the date hereof, payable to such Lender in a principal amount equal to the
amount of its Commitment as originally in effect and otherwise duly completed.

            (b) The date, amount, Type, interest rate and duration of Interest
Period (if applicable) of each Loan made by each Lender to the Company, and each
payment 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 such Lender to make any such recordation
or endorsement shall not affect the obligations of the Company to make a payment
when due of any amount owing hereunder or under such Note in respect of the
Loans.

            (c) No Lender shall be entitled to have its Note substituted or
exchanged for any reason, or subdivided for promissory notes of lesser
denominations, except in connection with a permitted assignment of all or any
portion of such Lender's Commitment, Loans and Note pursuant to Section 12.06
hereof (and, if requested by any Lender, the Company agrees to so exchange any
Note).

            2.08 OPTIONAL PREPAYMENTS AND CONVERSIONS OR CONTINUATIONS OF LOANS.
Subject to Sections 2.10, 4.04 and 5.05 hereof, the Company shall have the right
to prepay Loans, or to Convert Loans of one Type into Loans of another Type or
Continue Loans of one Type as Loans of the same Type, at any time or from time
to time, PROVIDED that:

            (a) the Company shall give the Administrative Agent notice of each
      such prepayment, Conversion or Continuation as provided in Section 4.05
      hereof (and, upon the date specified in any such notice of prepayment, the
      amount to be prepaid shall become due and payable hereunder); and

            (b) any Conversion or Continuation of Eurodollar Loans shall be
      subject to the proviso set forth at the end of Section 2.01 hereof.

Notwithstanding the foregoing, and without limiting the rights and remedies of
the Lenders under Section 10 hereof, in the event that any Event of Default
shall have occurred and be continuing, the Administrative Agent may (and at the
request of the Majority Lenders shall) suspend the right of the Company to
Convert any Loan into a Eurodollar Loan, or to Continue any Loan as a Eurodollar
Loan, in which event all Eurodollar Loans shall be Converted (on the last day(s)
of the respective Interest Periods therefor) into ABR Loans.

            2.09  MANDATORY PREPAYMENTS AND REDUCTIONS OF COMMITMENTS.

            (a) BORROWING BASE. If the aggregate principal amount of the Loans
shall at any time exceed the lesser of (i) the aggregate amount of the
Commitments in effect at such time and (ii) the Borrowing Base at such time
(such condition being herein called an "OVERAGE"), the Company shall (subject to
Sections 2.10 and 5.05 hereof) prepay Loans in an amount equal to the amount of
such overage. Such prepayment shall be made no later than the date 30 days
following the date on which such overage first occurred unless the Company shall
theretofore have eliminated such overage (through a redetermination of the
Borrowing Base as provided in Section 2.11 hereof) in a manner acceptable to the
Administrative Agent and the Required Lenders, PROVIDED that if the Borrowing
Base has decreased by reason of a sale, lease, transfer or other disposition of
any Property of the Company or any of its Restricted Subsidiaries or any other
voluntary action taken by an Obligor, such prepayment shall be made on such
earlier date or dates as the Required Lenders (through the Administrative Agent)
may specify to the Company.

            (b) THRESHOLD AMOUNT. If the aggregate principal amount of the Loans
shall at any time after the first anniversary of the Closing Date exceed the
Threshold Amount at such time, the Company shall (subject to Sections 2.10 and
5.05 hereof) immediately prepay Loans in an amount equal to such excess.
Notwithstanding any provision of this Agreement 
<PAGE>
                                      -31-

to the contrary, on any date after the first anniversary of the Closing Date,
any reference in this Agreement or any of the other Basic Documents to the
"Threshold Amount" shall be deemed to be a reference to the "Borrowing Base."

            (c) EXCESS CASH FLOW. If at the end of any fiscal quarter of the
Company the aggregate principal amount of the Loans shall exceed the Threshold
Amount (each such fiscal quarter, a "SPECIFIED QUARTER"), then the Company shall
(subject to Sections 2.10 and 5.05 hereof) prepay a principal amount of the
Loans and accrued interest thereon in an aggregate amount equal to 100% of
Excess Cash Flow for such Specified Quarter. Such prepayment shall be made no
later than the date 30 days after the end of such Specified Quarter.

            (d) Any prepayment of principal of the Loans made pursuant to clause
(b) or (c) of this Section 2.09 shall automatically reduce the Borrowing Base
and the Threshold Amount, if applicable, by the amount of such prepayment.

            2.10 MINIMUM AMOUNT OUTSTANDING. Notwithstanding anything in
Sections 2.08 and 2.09 to the contrary (but without limiting Section 3.01
hereof), following the making of the initial Loan hereunder, the Company shall
not, nor shall the Company be obligated to, prepay any Loan or Loans if, after
giving effect to such prepayment, the aggregate principal amount of Loans
outstanding would be less than $100.

            2.11  BORROWING BASE AND THRESHOLD AMOUNT DETERMINATIONS AND
COMPUTATIONS.

            (a) INITIAL AMOUNTS. The Borrowing Base in effect on the date of
this Agreement is hereby determined to be $65,000,000 (as such amount may be
reduced pursuant to Section 2.09(d) hereof), and the Threshold Amount in effect
on the date of this Agreement is hereby determined to be $45,000,000. The
Borrowing Base and the Threshold Amount shall remain at the respective amounts
determined pursuant to the first sentence of this Section 2.11(a) until the date
on which the Administrative Agent shall next establish the Borrowing Base and
Threshold Amount (prior to the first anniversary of the Closing Date) as
provided in Section 2.11(b) hereof or Section 2.11(c) hereof.

            (b) SCHEDULED REDETERMINATIONS. (i) As promptly as practicable, but
      in any event within 30 days, following the receipt of any Reserve Report
      required to be delivered under Section 9.01(e), the Administrative Agent
      (in consultation with the Lenders) shall (A) redetermine the Borrowing
      Base and the Threshold Amount on the basis of such Reserve Report in the
      manner provided in clause (ii) of this Section 2.11(b), (B) notify the
      Lenders of such redetermination and (C) if such redetermination is
      approved by the Required Lenders (provided that if any Lender
<PAGE>
                                      -32-

      fails to respond to the notification from the Administrative Agent
      delivered pursuant to clause (B) within 15 days of the delivery thereof,
      such Lender shall be deemed to have approved the proposed
      redetermination), notify the Lenders of the Borrowing Base and, if prior
      to the first anniversary of the Closing Date, the Threshold Amount as so
      redetermined. Such redetermined Borrowing Base and the Threshold Amount
      shall become effective on the date on which the Company receives written
      notice of the redetermined Borrowing Base or Threshold Amount, as
      applicable (or such later date as notified by the Administrative Agent to
      the Company and the Lenders) and shall remain effective until again
      redetermined pursuant to this Section 2.11. Each date on which a
      redetermination of the Borrowing Base or, if prior to the first
      anniversary of the Closing Date, the Threshold Amount becomes effective as
      provided in the preceding sentence is herein called a "REDETERMINATION
      DATE".

                     (ii) Each redetermination by the Administrative Agent of
            the Borrowing Base (and the Required Lenders' approval thereof)
            shall be made on the basis of parameters which may include the
            Present Value of Reserves attributable to O&G Properties as set
            forth in the related Reserve Report, as adjusted by the
            Administrative Agent with the approval of the Required Lenders, in
            its and their reasonable discretion, using the rates, factors,
            values, estimates, assumptions and computations set forth in such
            Reserve Report and any other relevant information or factors (such
            adjustments being herein called "BORROWING BASE ASSUMPTIONS").

            (c) UNSCHEDULED REDETERMINATIONS. Not later than the date 45 days
after any Redetermination Event, the Administrative Agent may (and (i) if
requested by the Required Lenders or (ii) if such Redetermination Event is an
event referred to in paragraph (b) of the definition of such term in Section
1.01 hereof, shall), by notice to the Company and the Lenders, re-establish the
Borrowing Base and, if prior to the first anniversary of the Closing Date, the
Threshold Amount with the approval of the Required Lenders. In determining the
Borrowing Base and, if prior to the first anniversary of the Closing Date, the
Threshold Amount pursuant to this Section 2.11(c), the Administrative Agent
shall (with the approval of the Required Lenders) be entitled to give effect to
the occurrence of any events or circumstances giving rise to or constituting the
relevant Redetermination Event. Any determination of the Borrowing Base
following a Redetermination Event referred to in paragraph (d) of the definition
of such term in Section 1.01 hereof shall be made by the Administrative Agent
and the Required Lenders in their sole discretion based on such factors as they
deem relevant. The effective date of the redetermined Borrowing Base and
Threshold Amount, if applicable, shall be established in accordance with Section
2.11(b) hereof, provided that no Reserve Report shall be required for a
determination of the Borrowing Base following a Redetermination Event referred
to in paragraph (d) of the definition of such term in Section 1.01 hereof.

            (d) DETERMINATIONS. Each determination of the Borrowing Base
pursuant to Sections 2.11(b) and (c) hereof shall be the Administrative Agent's
determination of the aggregate value of the Obligor's interest in the O&G
Properties, and shall be the Borrowing Base until the date on which the
Administrative Agent, with the approval of the Required Lenders, shall next
establish the Borrowing Base as provided in Section 2.11(b) or 2.11(c) hereof.
Each determination of the Threshold Amount pursuant to Sections 2.11(b) and (c)
hereof shall be the Administrative Agent's, with the approval of the Required
Lenders, determination of the aggregate value of the Obligor's interest in the
O&G Properties, and shall be the Threshold Amount until the date on which the
Administrative Agent, with the approval of the Required Lenders, shall next
establish the Threshold Amount as provided in Section 2.11(b) or 2.11(c) hereof.
In determining the Borrowing Base and the Threshold Amount pursuant to Sections
2.11(b) and (c) hereof or the definition of "Present Value of Reserves" in
Section 1.01 hereof, the Administrative Agent shall (in consultation with the
Lenders), (x) employ the oil and gas lending criteria generally employed by
Chase on the date of such determination with respect to borrowers similar to the
Company, and (y) be entitled to take into account such rates, factors, values,
estimates and assumptions as the Administrative Agent shall, in its reasonable
discretion, deem relevant for the purpose of such determination, together with
the report most recently delivered under Section 9.01(e) hereof.

            Section 3.  PAYMENTS OF PRINCIPAL AND INTEREST.

            3.01 REPAYMENT OF LOANS. The Company hereby promises to pay to the
Administrative Agent for account of each Lender the entire outstanding principal
amount of such Lender's Loans, and each Loan shall mature, on the Commitment
Termination Date.

            3.02 INTEREST. The Company hereby promises to pay to the
Administrative Agent for account of each Lender interest on the unpaid principal
amount of each Loan made by such Lender for the period from and including the
date of such Loan to but excluding the date such Loan shall be paid in full, at
the following rates per annum:

            (a) during such periods as such Loan is an ABR Loan, the Alternate
      Base Rate (as in effect from time to time) PLUS the Applicable Margin; and

            (b) during such periods as such Loan is a Eurodollar Loan, for each
      Interest Period relating thereto, the Eurodollar Rate for such Loan for
      such Interest Period PLUS the Applicable Margin.
<PAGE>
                                      -34-

Notwithstanding the foregoing, the Company hereby promises to pay to the
Administrative Agent for account of each Lender interest at the applicable
Post-Default Rate:

            (x)   on any principal of any Loan made by such Lender and on any
      other amount payable by the Company hereunder or under the Note held by
      such Lender to or for account of such Lender, that shall not be paid in
      full when due (whether at stated maturity, by acceleration, by mandatory
      prepayment or otherwise), for the period from and including the due date
      thereof to but excluding the date the same is paid in full and

            (y) on any principal of any Loan made by such Lender during any
      period when an Event of Default shall have occurred under Section 10(a)
      hereof and for so long as such Event of Default shall be continuing.

Accrued interest on each Loan shall be payable (i) in the case of an ABR Loan,
on the last Business Day of each month, (ii) in the case of a Eurodollar Loan,
on the last day of each Interest Period therefor and, if such Interest Period is
longer than three months, at three-month intervals following the first day of
such Interest Period, and (iii) in the case of any Loan, upon the payment or
prepayment thereof or the Conversion of such Loan to a Loan of another Type (but
only on the principal amount so paid, prepaid or Converted), except that
interest payable at the Post-Default Rate shall be payable from time to time on
demand. Promptly after the determination of any interest rate provided for
herein or any change therein, the Administrative Agent shall give notice thereof
to the Lenders to which such interest is payable and to the Company.

            Section 4.  PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

            4.01  PAYMENTS.

            (a) Except to the extent otherwise provided herein, all payments of

            (b) Any Lender for whose account any such payment is to be made may
(but shall not be obligated to) debit the amount of any such payment that is not
made by such time to any ordinary deposit account of the Company with such
Lender (with notice to the Company and the Administrative Agent), PROVIDED that
such Lender's failure to give such notice shall not affect the validity thereof.


            (c) The Company shall, at the time of making each payment under this
Agreement or any Note for account of any Lender, specify to the Administrative
Agent (which shall so notify the intended recipient(s) thereof) the Loans or
other amounts payable by the Company hereunder to which such payment is to be
applied (and in the event that the Company fails to so specify, or if an Event
of Default has occurred and is continuing, the Administrative Agent may
distribute such payment to the Lenders for application in such manner as it or
the Majority Lenders, subject to Section 4.02 hereof, may determine to be
appropriate).

            (d) Each payment received by the Administrative Agent under this
Agreement or any Note for account of any Lender shall be paid by the
Administrative Agent promptly to such Lender, in immediately available funds,

would otherwise fall on a day that 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.

            4.02 PRO RATA TREATMENT. Except to the extent otherwise provided
herein: (a) each borrowing from the Lenders under Section 2.01 hereof shall be
made from the Lenders, each payment of commitment fee under Section 2.04 hereof
shall be made for account of the Lenders, and each termination or reduction of
the amount of the Commitments under Section 2.03 hereof shall be applied to the
respective Commitments of the Lenders, pro rata according to the amounts of
their respective Commitments; (b) except as otherwise provided in Section 5.04
hereof, Eurodollar Loans having the same Interest Period shall be allocated pro
rata among the Lenders according to the amounts of their respective Commitments
(in the case of the making of Loans) or their respective Loans (in the case of
Conversions and Continuations of Loans); (c) each payment or prepayment of
principal of Loans by the Company shall be made for account of the Lenders pro
rata in accordance with the respective unpaid principal amounts of the Loans
held by them; and (d) each payment of interest on Loans by the Company shall be

            4.03 COMPUTATIONS. Interest on Loans and commitment fee shall be

different Types or, in the case of Eurodollar Loans, having different Interest
Periods at the same time hereunder to be deemed separate borrowings, Conversions
and prepayments for purposes of the foregoing, one for each Type or Interest
Period), PROVIDED that the aggregate principal amount of Eurodollar Loans having
the same Interest Period shall be in an amount at least equal to $5,000,000 or a
larger multiple of $1,000,000 and, if any Eurodollar Loans would otherwise be in
a lesser principal amount for any period, such Loans shall be ABR Loans during
such period.

Agent of determinations or reductions of the Commitments and of borrowings,
Conversions, Continuations and optional prepayments of Loans, of Types of Loans

Borrowing or prepayment of, Conversions
into, Continuations as, or duration of
Interest Period for, Eurodollar Loans                     3

Each such notice of termination or reduction shall specify the amount of the

Conversion, Continuation or optional prepayment shall specify the Loans to be
borrowed, Converted, Continued or prepaid and the amount (subject to Section
4.04 hereof) and Type of each Loan to be borrowed, Converted, Continued or
prepaid and the date of borrowing, Conversion, Continuation or optional
prepayment (which shall be a Business Day). Each such notice of the duration of
an Interest Period shall specify the Loans to which such Interest Period is to
relate. The Administrative Agent shall promptly notify the Lenders of the
contents of each such notice. In the event that the Company fails to select the
Type of Loan, or the duration of any Interest Period for any Eurodollar Loan,
within the time period and otherwise as provided in this Section 4.05, such Loan
(if outstanding as a Eurodollar Loan) will be automatically Converted into an
ABR Loan on the last day of the then current Interest Period for such Loan or
(if outstanding as an ABR Loan) will remain as, or (if not then outstanding)
will be made as, an ABR Loan.

            4.06 NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT. Unless the
Administrative Agent shall have been notified by a Lender or the Company (the
"PAYOR") prior to the date on which the Payor is to make payment to the
Administrative Agent of (in the case of a Lender) the proceeds of a Loan to be
made by such Lender hereunder 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 the "REQUIRED PAYMENT"), which notice shall be
effective upon receipt, that the Payor 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

                                      -38-

be required to), make the amount thereof available to the intended recipient(s)
on such date; and, if the Payor 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 (the
"ADVANCE 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 Federal Funds Rate for such day and, if such recipient(s) shall
fail promptly to make such payment, the Administrative Agent shall be entitled
to recover such amount, on demand, from the Payor, together with interest as
aforesaid, PROVIDED that if neither the recipient(s) nor the Payor shall return
the Required Payment to the Administrative Agent within three Business Days of
the Advance Date, then, retroactively to the Advance Date, the Payor and the
recipient(s) shall each be obligated to pay interest on the Required Payment as
follows:

                      (i) if the Required Payment shall represent a payment to
            be made by the Company to the Lenders, the Company and the
            recipient(s) shall each be obligated retroactively to the Advance
            Date to pay interest in respect of the Required Payment at the
            Post-Default Rate (without duplication of the obligation of the
            Company under Section 3.02 hereof to pay interest on the Required
            Payment at the Post-Default Rate), it being understood that the
            return by the recipient(s) of the Required Payment to the
            Administrative Agent shall not limit such obligation of the Company
            under said Section 3.02 to pay interest at the Post-Default Rate in
            respect of the Required Payment; and

                     (ii) if the Required Payment shall represent proceeds of a
            Loan to be made by the Lenders to the Company, the Payor and the
            Company shall each be obligated retroactively to the Advance Date to
            pay interest in respect of the Required Payment pursuant to
            whichever of the rates specified in Section 3.02 hereof is
            applicable to the Type of such Loan, it being understood that the
            return by the Company of the Required Payment to the Administrative
            Agent shall not limit any claim the Company may have against the
            Payor in respect of such Required Payment.

            4.07  SHARING OF PAYMENTS, ETC.

            (a) Each Obligor agrees that, in addition to (and without limitation
of) any right of set-off, banker's lien or counterclaim a Lender may otherwise
have, each Lender shall be entitled, at its option (to the fullest extent
permitted by law), to set off and apply any deposit (general or special, time or
demand, provisional or final), or other indebtedness, held by it for the credit
or account of such Obligor 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 
<PAGE>
                                      -39-

amount payable to such Lender hereunder, that is not paid when due (regardless
of whether such deposit or other indebtedness are then due to such Obligor), in
which case it shall promptly notify such Obligor 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 from any Obligor payment of any
principal of or interest on any Loan owing to it or payment of any other amount
under this Agreement or any other Loan Document through the exercise of any
right of set-off, banker's lien or counterclaim or similar right or otherwise
(other than from the Administrative Agent as provided herein), and, as a result
of such payment, such Lender shall have received a greater percentage of the
principal of or interest on the Loans or such other amounts then due hereunder
or thereunder by such Obligor to such Lender than the percentage received by any
other Lender, it shall promptly purchase from such other Lenders participations
in (or, if and to the extent specified by such Lender, direct interests in) the
Loans or such other amounts, respectively, owing to such other Lenders (or in
interest due thereon, as the case may be) 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 that
may be incurred by such Lender in obtaining or preserving such excess payment)
pro rata in accordance with the unpaid principal of and/or interest on the Loans
or such other amounts, respectively, owing 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.

            (c) The Company agrees that any Lender so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Lender were a direct holder of Loans or other amounts (as the case
may be) owing to such Lender in the amount of such participation.

            (d) Nothing contained herein shall require any Lender to exercise
any such right or shall affect the right of any Lander to exercise, and retain
the benefits of exercising, any such right with respect to any other
indebtedness or obligation of any Obligor. 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 4.07 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 4.07 to
share in the benefits of any recovery on such secured claim.

            Section 5.  YIELD PROTECTION, ETC.

            5.01  ADDITIONAL COSTS.

            (a) The Company shall pay directly to each Lender from time to time
such amounts as such Lender may reasonably determine to be necessary to
compensate such Lender for any costs that such Lender determines are
attributable to its making or maintaining of 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
that:

                      (i) shall subject any Lender (or its Applicable Lending
            Office for any of such Loans) to any tax, duty or other charge in
            respect of such Loans or its Note or changes the basis of taxation
            of any amounts payable to such Lender under this Agreement or its
            Note in respect of any of such Loans (excluding changes in the rate
            of tax on the overall net income of such Lender or of such
            Applicable Lending Office by the jurisdiction in which such Lender
            has its principal office or such Applicable Lending Office); or

                     (ii) imposes or modifies any reserve, special deposit or
            similar requirements (other than the Reserve Requirement utilized in
            the determination of the Eurodollar Rate for such Loan) relating to
            any extensions of credit or other assets of, or any deposits with or
            other liabilities of, such Lender (including, without limitation,
            any of such Loans or any deposits referred to in the definition of
            "Eurodollar Base Rate" in Section 1.01 hereof), or any commitment of
            such Lender (including, without limitation, the Commitment of such
            Lender hereunder); or

                    (iii) imposes any other condition affecting this Agreement
            or its Note (or any of such extensions of credit or liabilities) or
            its Commitment.

If any Lender requests compensation from the Company under this 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 thereafter to make or Continue
Eurodollar Loans, or to Convert ABR Loans into Eurodollar Loans, until the
Regulatory Change giving rise to such request ceases to be in effect (in which
case the provisions of Section 5.04 hereof shall be applicable), PROVIDED that
such suspension shall not affect the right of such Lender to receive the
compensation so requested.
<PAGE>
                                      -41-

            (b) Without limiting the effect of the foregoing provisions of this
Section 5.01 (but without duplication), the Company shall pay directly to each
Lender from time to time on request such amounts as such Lender may reasonably
determine to be necessary to compensate such Lender (or, without duplication,
the bank holding company of which such Lender is a subsidiary) for any costs
that it determines are attributable to the maintenance by such Lender (or any
Applicable Lending Office or such bank holding company), pursuant to any law or
regulation or any interpretation, directive or request (whether or not having
the force of law and whether or not failure to comply therewith would be
unlawful) of any court or governmental or monetary authority (i) following any
Regulatory Change or (ii) implementing any risk-based capital guideline or other
requirement (whether or not having the force of law and whether or not the
failure to comply therewith would be unlawful) hereafter issued by any
government or governmental or supervisory authority implementing at the national
level the Basle Accord, of capital in respect of its Commitment or Loans (such
compensation to 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 or such bank holding company) to a level below that which such Lender (or
any Applicable Lending Office or such bank holding company) could have achieved
but for such law, regulation, interpretation, directive or request).

            (c) Each Lender shall notify the Company of any event occurring
after the date hereof entitling such Lender to compensation under paragraph (a)
or (b) of this Section 5.01 as promptly as practicable, but in any event within
45 days, after such Lender obtains actual knowledge thereof; PROVIDED that (i)
if any Lender fails to give such notice within 45 days after it obtains actual
knowledge of such an event, such Lender shall, with respect to compensation
payable pursuant to this Section 5.01 in respect of any costs resulting from
such event, only be entitled to payment under this Section 5.01 for costs
incurred from and after the date 45 days prior to the date that such Lender does
give such notice and (ii) each Lender will designate a different Applicable
Lending Office for the Loans of such Lender affected by such event if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the sole opinion of such Lender, be disadvantageous to such
Lender, except that such Lender shall have no obligation to designate an
Applicable Lending Office located in the United States of America. Each Lender
will furnish to the Company a certificate setting forth in reasonable detail the
basis and amount of each request by such Lender for compensation under paragraph
(a) or (b) of this Section 5.01. Determinations and allocations by any Lender
for purposes of this Section 5.01 of the effect of any Regulatory Change
pursuant to paragraph (a) of this Section 5.01, or of the effect of capital
maintained pursuant to paragraph (b) of this Section 5.01, on its costs or rate
of return of maintaining Loans or its obligation to make Loans, or on amounts
receivable by it in respect of Loans, and of the amounts required to 
<PAGE>
                                      -42-

compensate such Lender under this Section 5.01, shall be conclusive, PROVIDED
that such determinations and allocations are made in good faith and on a
reasonable basis.

            5.02 LIMITATION ON TYPES OF LOANS. Anything herein to the contrary
notwithstanding, if, on or prior to the determination of any Eurodollar Base
Rate for any Interest Period:

            (a) the Administrative Agent determines in good faith, which
      determination shall be conclusive, that quotations of interest rates for
      the relevant deposits referred to in the definition of "Eurodollar Base
      Rate" in Section 1.01 hereof 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 Majority Lenders determine in good faith, which
      determination shall be conclusive, and notify the Administrative Agent
      that the relevant rates of interest referred to in the definition of
      "Eurodollar Base Rate" in Section 1.01 hereof upon the basis of which the
      rate of interest for Eurodollar Loans for such Interest Period is to be
      determined are not likely adequately to cover the cost to such Lenders of
      making or maintaining Eurodollar Loans for such Interest Period;

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, to Continue
Eurodollar Loans or to Convert ABR Loans into Eurodollar Loans, and the Company
shall, on the last day(s) of the then current Interest Period(s) for the
outstanding Eurodollar Loans, either prepay such Loans or Convert such Loans
into ABR Loans in accordance with Section 2.08 hereof.

            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 (and, in the sole opinion of such Lender, the designation of a
different Applicable Lending Office would either not avoid such unlawfulness or
would be disadvantageous to such Lender), then such Lender shall promptly notify
the Company thereof (with a copy to the Administrative Agent) and such Lender's
obligation to make or Continue, or to Convert Loans of any other Type into,
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
hereof shall be applicable).

            5.04 TREATMENT OF AFFECTED LOANS. If the obligation of any Lender to
make Eurodollar Loans or to Continue, or to Convert ABR Loans into, Eurodollar
Loans shall be suspended pursuant to Section 5.01 or 5.03 hereof, such Lender's
Eurodollar Loans shall be 
<PAGE>
                                      -43-

automatically Converted into ABR Loans on the last day(s) of the then current
Interest Period(s) for Eurodollar Loans (or, in the case of a Conversion
resulting from a circumstance described in Section 5.03 hereof, on such earlier
date as such Lender may specify to the Company with a copy to the Administrative
Agent) and, unless and until such Lender gives notice as provided below that the
circumstances specified in Section 5.01 or 5.03 hereof that gave rise to such
Conversion no longer exist:

            (a) to the extent that such Lender's Eurodollar Loans have been so
      Converted, all payments and prepayments of principal that would otherwise
      be applied to such Lender's Eurodollar Loans shall be applied instead to
      its ABR Loans; and

            (b) all Loans that would otherwise be made or Continued by such
      Lender as Eurodollar Loans shall be made or Continued instead as ABR
      Loans, and all ABR Loans of such Lender that would otherwise be Converted
      into Eurodollar Loans shall remain as ABR Loans.

If such Lender gives notice to the Company with a copy to the Administrative
Agent that the circumstances specified in Section 5.01 or 5.03 hereof that gave
rise to the Conversion of such Lender's Eurodollar Loans pursuant to this
Section 5.04 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans made by other
Lenders are outstanding, such Lender's ABR Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Eurodollar Loans, to the extent necessary so that, after giving
effect thereto, all Loans are allocated among the Lenders ratably (as to
principal amounts, Types and Interest Periods) in accordance with their
respective Commitments.

            5.05 COMPENSATION. The Company shall pay to the Administrative Agent
for account of each Lender, upon the written request of such Lender through the
Administrative Agent (which request shall set forth in reasonable detail the
basis therefor), such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense (including, without limitation, any loss, cost or expense incurred by
reason of the liquidation or reemployment of deposits or other funds required by
such Lender to fund its Eurodollar Loans but excluding in any event the loss of
anticipated profits) that such Lender determines is attributable to:

            (a) any payment, mandatory or optional prepayment or Conversion of a
      Eurodollar Loan made by such Lender for any reason (including, without
      limitation, the acceleration of the Loans pursuant to Section 10 hereof)
      on a date other than the last day of the Interest Period for such Loan; or
<PAGE>
                                      -44-

            (b) any failure by the Company for any reason (including, without
      limitation, the failure of any of the conditions precedent specified in
      Section 7 hereof to be satisfied) to borrow a Eurodollar Loan from such
      Lender on the date for such borrowing specified in the relevant notice of
      borrowing given pursuant to Section 2.02 hereof (other than as a result of
      a default by such Lender of its obligations pursuant to Section 2.01 or
      2.02 hereof or by the Administrative Agent of its obligations pursuant to
      Section 2.02 hereof).

            5.06  U.S. TAXES.

            (a) The Company agrees to pay to each Lender that is not a U.S.
Person such additional amounts as are necessary in order that the net payment of
any amount due to such non-U.S. Person hereunder after deduction for or
withholding in respect of any U.S. Taxes (other than U.S. Taxes attributable to
payments that are effectively connected with the conduct of a trade or business
within the United States of America, within the meaning of Section 864 of the
Code as in effect on the date hereof) imposed with respect to such payment (or
in lieu thereof, payment of such U.S. Taxes by such non-U.S. Person), will not
be less than the amount stated herein to be then due and payable, PROVIDED that
the foregoing obligation to pay such additional amounts shall not apply:

                      (i) to any payment to any Lender hereunder unless such
            Lender is, on the date hereof (or on the date it becomes a Lender
            hereunder as provided in Section 12.06(b) hereof), on the date of
            each payment hereunder and on the date of any change in the
            Applicable Lending Office of such Lender, either entitled to submit
            a Form 1001 (relating to such Lender and entitling it to a complete
            exemption from withholding on all interest to be received by it
            hereunder in respect of the Loans) or Form 4224 (relating to all
            interest to be received by such Lender hereunder in respect of the
            Loans), or

                     (ii) to any U.S. Taxes imposed solely by reason of the
             failure by such non-U.S. Person (or, if such non-U.S. Person is not
             the beneficial owner of the relevant Loan, such beneficial owner)
             to comply with applicable certification, information, documentation
             or other reporting requirements concerning the nationality,
             residence, identity or connections with the United States of
             America of such non- U.S. Person (or such beneficial owner, as the
             case may be) if such compliance is required by statute or
             regulation of the United States of America as a precondition to
             relief or exemption from such U.S. Taxes.

For the purposes of this Section 5.06(a), (A) "U.S. PERSON" shall mean a
citizen, national or resident of the United States of America, a corporation,
partnership or other entity created or 
<PAGE>
                                      -45-

organized in or under any laws of the United States of America or any State
thereof, or any estate or trust that is subject to Federal income taxation
regardless of the source of its income, (B) "U.S. TAXES" shall mean any present
or future tax, assessment or other charge or levy imposed by or on behalf of the
United States of America or any taxing authority thereof or therein, (C) "FORM
1001" shall mean Form 1001 (Ownership, Exemption, or Reduced Rate Certificate)
of the Department of the Treasury of the United States of America and (D) "FORM
4224" shall mean Form 4224 (Exemption from Withholding of Tax on Income
Effectively Connected with the Conduct of a Trade or Business in the United
States) of the Department of the Treasury of the United States of America. Each
of the Forms referred to in the foregoing clauses (C) and (D) shall include such
successor and related forms as may from time to time be adopted by the relevant
taxing authorities of the United States of America to document a claim to which
such Form relates.

            (b) Within 30 days after paying any amount to the Administrative
Agent or any Lender from which it is required by law to make any deduction or
withholding, and within 30 days after it is required by law to remit such
deduction or withholding to any relevant taxing or other authority, the Company
shall deliver to the Administrative Agent for delivery to such non-U.S. Person
evidence satisfactory to such Person of such deduction, withholding or payment
(as the case may be).

            (c) If any Lender shall be entitled to compensation under this
Section 5.06, such Lender, within a reasonable time after becoming entitled to
such compensation, shall (unless otherwise required by a Government Authority or
a result of any law, rule, regulation, order or similar directive applicable to
such Lender) designate a different Applicable Lending Office from that initially
selected by such Lender to which payments are to be made under the Basic
Documents, if such designation would avoid the need for (or reduce the amount
of) such compensation and would not, in the sole opinion of such Lender, be
otherwise disadvantageous to such Lender.

            5.07 REPLACEMENT OF LENDERS. If any Lender defaults in its
obligation to make Loans under Section 2.01 hereof or requests compensation
pursuant to Section 5.01 or 5.06 hereof, or any Lender's obligation to make or
Continue, or to Convert Loans of any Type into, any other Type of Loan shall be
suspended pursuant to Section 5.01 or 5.03 hereof (any such Lender so defaulting
or requesting such compensation or whose obligations are so suspended, being
herein called a "RELEVANT LENDER"), the Company, upon three Business Days notice
given when no Default shall have occurred and be continuing, may require that
such Relevant Lender transfer all of its right, title and interest under this
Agreement and such Relevant Lender's Notes to any bank or other financial
institution identified by the Company that is satisfactory to the Agent, in its
discretion reasonably exercised (a "PROPOSED LENDER"), provided that (i) such
Proposed Lender agrees to assume
<PAGE>
                                      -46-

all of the obligations of such Relevant Lender hereunder, and to purchase all of
such Relevant Lender's Loans hereunder for consideration equal to the aggregate
outstanding principal amount of such Relevant Lender's Loans, together with
interest thereon to the date of such purchase, and arrangements satisfactory to
such Relevant Lender are made for payment to such Relevant Lender of all other
amounts payable hereunder to such Relevant Lender on or prior to the date of
such transfer (including any fees accrued hereunder and any amounts that would
be payable under Section 5.05 hereof as if all of such Relevant Lender's Loans
were being prepaid in full on such date) and (ii) if such Relevant Lender has
requested compensation pursuant to Section 5.01 or 5.06 hereof, such Proposed
Lender's aggregate requested compensation, if any, paid pursuant to Section 5.01
or 5.06 hereof with respect to such Relevant Lender's Loans is lower than that
of the Relevant Lender. Subject to the provisions of Section 12.06(b) hereof,
such Proposed Lender shall be a "Lender" for all purposes hereunder. Without
prejudice to the survival of any other agreement of the Company hereunder, the
agreements of the Company contained in Sections 5.01, 5.06 and 12 hereof
(without duplication of any payments made to such Relevant Lender by the Company
or the Proposed Lender) shall survive for the benefit of such Relevant Lender
under this Section 5.07 with respect to the time prior to such replacement.

            Section 6.  GUARANTEE.

            6.01 THE GUARANTEE. The Subsidiary Guarantors hereby jointly and
severally guarantee to each Lender and the Administrative Agent and their
respective successors and assigns the prompt payment in full when due (whether
at stated maturity, by acceleration or otherwise) of the principal of and
interest on the Loans made by the Lenders to, and the Note held by each Lender
of, the Company and all other amounts from time to time owing to the Lenders or
the Administrative Agent by the Company under this Agreement and under the Notes
and by any Obligor under any of the other Loan Documents, and all obligations of
the Company or any of its Restricted Subsidiaries to any Lender in respect of
any Swap Transactions, in each case strictly in accordance with the terms
thereof (such obligations being herein collectively called the" GUARANTEED
OBLIGATIONS"). The Subsidiary Guarantors hereby further jointly and severally
agree that if the Company shall fail to pay in full when due (whether at stated
maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the
Subsidiary Guarantors will promptly pay the same, without any demand or notice
whatsoever, and that in the case of any extension of time of payment or renewal
of any of the Guaranteed Obligations, the same will be promptly paid in full
when due (whether at extended maturity, by acceleration or otherwise) in
accordance with the terms of such extension or renewal.

            6.02 OBLIGATIONS UNCONDITIONAL. The obligations of the Subsidiary
Guarantors under Section 6.01 hereof are absolute and unconditional, joint and
several, irrespective of the value, genuineness, validity, regularity or
enforceability of the obligations of the Company under this Agreement, the Notes
or any other agreement or instrument referred to herein or therein, or any
substitution, release or exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section 6.02 that the obligations of the
Subsidiary Guarantors hereunder shall be absolute and unconditional, joint and
several, under any and all circumstances. Without limiting the generality of the
foregoing, it is agreed that the occurrence of any one or more of the following
shall not alter or impair the liability of the Subsidiary Guarantors hereunder
which shall remain absolute and unconditional as described above:

                      (i) at any time or from time to time, without notice to
            the Subsidiary Guarantors, the time for any performance of or
            compliance with any of the Guaranteed Obligations shall be extended,
            or such performance or compliance shall be waived;

                     (ii) any of the acts mentioned in any of the provisions of
            this Agreement or the Notes or any other agreement or instrument
            referred to herein or therein shall be done or omitted;

                    (iii) the maturity of any of the Guaranteed Obligations
            shall be accelerated, or any of the Guaranteed Obligations shall be
            modified, supplemented or amended in any respect, or any right under
            this Agreement or the Notes or any other agreement or instrument
            referred to herein or therein shall be waived or any other guarantee
            of any of the Guaranteed Obligations or any security therefor shall
            be released or exchanged in whole or in part or otherwise dealt
            with; or

                     (iv) any lien or security interest granted to, or in favor
            of, the Administrative Agent or any Lender or Lenders as security

of payment, protest and all notices whatsoever, and any requirement that the
Administrative Agent or any Lender exhaust any right, power or remedy or proceed
against the Company under this Agreement or the Notes or any other agreement or
instrument referred to herein or therein, or against any other Person under any
other guarantee of, or security for, any of the Guaranteed Obligations. Each
Subsidiary Guarantor agrees that its obligations pursuant
<PAGE>
                                      -48-

to this Section 6 shall not be affected by any assignment or participation
entered into by any Lender pursuant to Section 12.06 hereof.

            6.03 REINSTATEMENT. The obligations of the Subsidiary Guarantors
under this Section 6 shall be automatically reinstated if and to the extent that
for any reason any payment by or on behalf of the Company in respect of the
Guaranteed Obligations is rescinded or must be otherwise restored by any holder
of any of the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise and the Subsidiary Guarantors jointly
and severally agree that they will indemnify the Administrative Agent and each
Lender on demand for all reasonable costs and expenses (including, without
limitation, fees of counsel) incurred by the Administrative Agent or such Lender
in connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment
constituted a preference, fraudulent transfer or similar payment under any
bankruptcy, insolvency or similar law.

            6.04 SUBROGATION. Each Subsidiary Guarantor hereby waives all rights
of subrogation or contribution, whether arising by contract or operation of law
(including, without limitation, any such right arising under the Bankruptcy
Code) or otherwise by reason of any payment by it pursuant to the provisions of
this Section 6 and further agrees with the Company for the benefit of each of
its creditors (including, without limitation, each Lender and the Administrative
Agent) that any such payment by it shall constitute a contribution of capital by
such Subsidiary Guarantor to the Company (or an investment in the equity capital
of the Company by such Subsidiary Guarantor).

            6.05 REMEDIES. The Subsidiary Guarantors jointly and severally agree
that, as between the Subsidiary Guarantors and the Lenders, the obligations of
the Company under this Agreement and the Notes may be declared to be forthwith
due and payable as provided in Section 10 hereof (and shall be deemed to have
become automatically due and payable in the circumstances provided in said
Section 10) for purposes of Section 6.01 hereof notwithstanding any stay,
injunction or other prohibition preventing such declaration (or such obligations
from becoming automatically due and payable) as against the Company and that, in
the event of such declaration (or such obligations being deemed to have become
automatically due and payable), such obligations (whether or not due and payable
by the Company) shall forthwith become due and payable by the Subsidiary
Guarantors for purposes of said Section 6.01.

            6.06 INSTRUMENT FOR THE PAYMENT OF MONEY. Each Subsidiary Guarantor
hereby acknowledges that the guarantee in this Section 6 constitutes an
instrument for the payment of money, and consents and agrees that any Lender or
the Administrative Agent, at its sole option, in the event of a dispute by such
Subsidiary Guarantor in the payment of any
<PAGE>
                                      -49-

moneys due hereunder, shall have the right to bring motion-action under New York
CPLR Section 3213.

            6.07 CONTINUING GUARANTEE. The guarantee in this Section 6 is a
continuing guarantee, and shall apply to all Guaranteed Obligations whenever
arising.

            6.08 RIGHTS OF CONTRIBUTION. The Subsidiary Guarantors hereby agree,
as between themselves, that if any Subsidiary Guarantor shall become an Excess
Funding Guarantor (as defined below) by reason of the payment by such Subsidiary
Guarantor of any Guaranteed Obligations, each other Subsidiary Guarantor shall,
on demand of such Excess Funding Guarantor (but subject to the next sentence),
pay to such Excess Funding Guarantor an amount equal to such Subsidiary
Guarantor's Pro Rata Share (as defined below and determined, for this purpose,
without reference to the Properties, debts and liabilities of such Excess
Funding Guarantor) of the Excess Payment (as defined below) in respect of such
Guaranteed Obligations. The payment obligation of a Subsidiary Guarantor to any
Excess Funding Guarantor under this Section 6.08 shall be subordinate and
subject in right of payment to the prior payment in full of the obligations of
such Subsidiary Guarantor under the other provisions of this Section 6 and such
Excess Funding Guarantor shall not exercise any right or remedy with respect to
such excess until payment and satisfaction in full of all of such obligations.

            For purposes of this Section 6.08, (i) "EXCESS FUNDING GUARANTOR"
shall mean, in respect of any Guaranteed Obligations, a Subsidiary Guarantor
that has paid an amount in excess of its Pro Rata Share of such Guaranteed
Obligations, (ii) "EXCESS PAYMENT" shall mean, in respect of any Guaranteed
Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro
Rata Share of such Guaranteed Obligations and (iii) "PRO RATA SHARE" shall mean,
for any Subsidiary Guarantor, the ratio (expressed as a percentage) of (x) the
amount by which the aggregate present fair saleable value of all Properties of
such Subsidiary Guarantor (excluding any shares of stock of any other Subsidiary
Guarantor) exceeds the amount of all the debts and liabilities of such
Subsidiary Guarantor (including contingent, subordinated, unmatured and
unliquidated liabilities, but excluding the obligations of such Subsidiary
Guarantor hereunder and any obligations of any other Subsidiary Guarantor that
have been Guaranteed by such Subsidiary Guarantor) to (y) the amount by which
the aggregate fair saleable value of all Properties of all of the Subsidiary
Guarantors exceeds the amount of all the debts and liabilities (including
contingent, subordinated, unmatured and unliquidated liabilities, but excluding
the obligations of the Company and the Subsidiary Guarantors hereunder and under
the other Loan Documents) of all of the Subsidiary Guarantors, determined (A)
with respect to any Subsidiary Guarantor that is a party hereto on the Closing
Date, as of the Closing Date, and (B) with respect to any other 
<PAGE>
                                      -50-

Subsidiary Guarantor, as of the date such Subsidiary Guarantor becomes a
Subsidiary Guarantor hereunder.

            6.09 GENERAL LIMITATION ON GUARANTEE OBLIGATIONS. In any action or
proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Subsidiary Guarantor under
Section 6.01 hereof would otherwise, taking into account the provisions of
Section 6.08 hereof, be held or determined to be void, invalid or unenforceable,
or subordinated to the claims of any other creditors, on account of the amount
of its liability under said Section 6.01, then, notwithstanding any other
provision hereof to the contrary, the amount of such liability shall, without
any further action by such Subsidiary Guarantor, any Lender, the Administrative
Agent or any other Person, be automatically limited and reduced to the highest
amount that is valid and enforceable and not subordinated to the claims of other
creditors as determined in such action or proceeding.

            Section 8. REPRESENTATIONS AND WARRANTIES. The Company represents
and warrants to the Administrative Agent and the Lenders that:

            8.01 CORPORATE EXISTENCE. Each of the Company and its Restricted
Subsidiaries: (a) is a corporation, partnership or other entity duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization; (b) has all requisite corporate or other power, and has all
material governmental licenses, authorizations, consents and approvals necessary
to own its assets and carry on its business as now being or as proposed to be
conducted; and (c) is qualified to do business and is in good standing in all
jurisdictions in which the nature of the business conducted by it makes such
qualification necessary and where failure so to qualify could (either
individually or in the aggregate) have a Material Adverse Effect.

            8.02 FINANCIAL CONDITION. The Company has heretofore furnished to
each of the Lenders consolidated and consolidating balance sheets of TGPC and
TVC, as predecessors in interest of the Company and its consolidated
Subsidiaries (in such capacity, 
<PAGE>
                                      -56-

the "PREDECESSORS") as at December 31, 1995 and the related consolidated and
consolidating statements of income, retained earnings and cash flows of the
Predecessors for the fiscal year ended on said date, and the consolidated and
consolidating balance sheets of the Predecessors as at September 30, 1996 and
the related consolidated and consolidating statements of income, retained
earnings and cash flows of the Predecessors for the nine-month period ended on
such date. All such financial statements are complete and correct and fairly
present the consolidated financial condition of the Predecessors and (in the
case of said consolidating financial statements) the respective unconsolidated
financial condition of the Predecessors, as at said dates and the consolidated
and unconsolidated results of their operations for the fiscal year and
nine-month period ended on said dates (subject, in the case of such financial
statements as at September 30, 1996, to normal year-end audit adjustments), all
in accordance with generally accepted accounting principles and practices
applied on a consistent basis. None of the Company nor any of its consolidated
Subsidiaries has on the date hereof any material contingent liabilities,
liabilities for taxes or royalties, unusual forward or long-term commitments or
unrealized or anticipated losses from any unfavorable commitments, except as
referred to or reflected or provided for in said balance sheets as at said
dates. Since December 31, 1995, except as contemplated by the Basic Documents,
there has been no material adverse change in the business, consolidated
condition (financial or otherwise), results of operations, Properties or
liabilities taken as a whole of the Predecessors (or the Company and its
Subsidiaries) from that set forth in said financial statements as at said date
except as disclosed on Schedule VII hereto (and on the Closing Date the Company
shall deliver a certificate of its Chief Financial Officer to the effect set
forth in this sentence).

            8.03 LITIGATION. Except as disclosed on Schedule V hereto, there are
no legal or arbitral proceedings, or any proceedings by or before any
governmental or regulatory authority or agency, now pending or (to the knowledge
of the Company) threatened against the Company or any of its Subsidiaries that,
if adversely determined could (either individually or in the aggregate) have a
Material Adverse Effect.

            8.04 NO BREACH. None of the execution and delivery of this Agreement
and the Notes and the other Basic Documents, the consummation of the
transactions herein and therein contemplated or compliance with the terms and
provisions hereof and thereof will conflict with or result in a breach of, or
require any consent under, the charter or by-laws of any Obligor, or any
applicable law or regulation, or any order, writ, injunction or decree of any
court or governmental authority or agency, or any agreement or instrument to
which the Company or any of its Restricted Subsidiaries is a party or by which
any of them or any of their Property is bound or to which any of them is
subject, or constitute a default under any such agreement or instrument, or
(except for the Liens created pursuant to the Security Documents) result in the
creation or imposition of any Lien upon any Property of the 
<PAGE>
                                      -57-

Company or any of its Restricted Subsidiaries pursuant to the terms of any such
agreement or instrument.

            8.05 ACTION. Other than the Notification and Report Form in respect
of the Acquisition and the Equity Documents furnished to the Department of
Justice and the Federal Trade Commission pursuant to the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, each Obligor has all necessary corporate
power, authority and legal right to execute, deliver and perform its obligations
under each of the Basic Documents to which it is a party; the execution,
delivery and performance by each Obligor of each of the Basic Documents to which
it is a party have been duly authorized by all necessary corporate action on its
part (including, without limitation, any required shareholder approvals); and
this Agreement has been duly and validly executed and delivered by each Obligor
and constitutes, and each of the Notes and the other Basic Documents to which it
is a party when executed and delivered by such Obligor (in the case of the
Notes, for value) will constitute, its legal, valid and binding obligation,
enforceable against each Obligor in accordance with its terms, except as such
enforceability may be limited by (a) bankruptcy, insolvency, reorganization,
moratorium or similar laws of general applicability affecting the enforcement of
creditors' rights and (b) the application of general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

            8.06 APPROVALS. No authorizations, approvals or consents of, and no
filings or registrations with, any governmental or regulatory authority or

legality, validity or enforceability hereof or thereof, except for filings and

            8.07 ERISA. Each Plan, and, to the knowledge of the Company, each
Multiemployer Plan, is in compliance in all material respects with, and has been
administered in all material respects in compliance with, the applicable
provisions of ERISA, the Code and any other Federal or State law, and no event
or condition has occurred and is continuing as to which the Company would be
under an obligation to furnish a report to the Lenders under Section 9.01(d)
hereof. The Company has no ERISA Affiliates other than its Subsidiaries.

            8.08 TAXES. The Company and its corporate Subsidiaries are members
of an affiliated group of corporations filing consolidated returns for Federal
income tax purposes, of which (prior to giving effect to the Acquisition) El
Paso is the "common parent" (within the meaning of Section 1504 of the Code) of
such group. Immediately following the Acquisition, the Company and its corporate
Subsidiaries will be members of an affiliated 
<PAGE>
                                      -58-

group of corporations filing consolidated returns for Federal income tax
purposes, of which the Company will be the "common parent" (within the meaning
of said Section 1504) of such group. Immediately following the Acquisition,
there will be no tax sharing, tax allocation or similar agreement in effect
providing for the manner in which tax payments owing by the members of such
affiliated group (whether in respect of Federal or state income or other taxes)
are allocated among the members of the group except as permitted by Section
9.13. Except for Federal income tax returns and other tax returns, the failure
of either of which to file or pay could not reasonably be expected to have a
Material Adverse Effect, the Company and its corporate Subsidiaries have filed
(either directly, or indirectly through El Paso (which term includes, for
purposes of this Section 8.08, El Paso's predecessors in interest)) all Federal
income tax returns and all other material tax returns that are required to be
filed by them and have paid (either directly, or indirectly through El Paso) all
taxes due pursuant to such returns or pursuant to any assessment received by El
Paso or by the Company or any of its Subsidiaries. The charges, accruals and
reserves on the books of the Company and its Subsidiaries in respect of taxes
and other governmental charges are, in the opinion of the Company, at all times
immediately following the Closing Date adequate.

            be the continuing or surviving corporation or (ii) any other such
            Restricted Subsidiary; PROVIDED that (x) if any such transaction
            shall be between a Restricted Subsidiary and a Wholly Owned
            Subsidiary which is a Restricted Subsidiary, the Wholly Owned

            Owned Subsidiary which is a Restricted Subsidiary of the Company;
            PROVIDED that if any such sale is by a Restricted Subsidiary
            Guarantor to a Restricted Subsidiary of the Company not a Subsidiary
            Guarantor, then such Restricted Subsidiary shall have assumed all of
            the obligations of such Subsidiary Guarantor hereunder and under the
            other Loan Documents;

                     (iv) the Company or any Restricted Subsidiary of the

            $2,000,000, (y) the Company shall or shall cause its Restricted

on a consolidated basis, in respect of all such obligations to exceed $500,000
payable in any period of 12 consecutive calendar months.

            9.13 TRANSACTIONS WITH AFFILIATES. Except as expressly permitted by

with a Person not an Affiliate.

            Without limiting the generality of the foregoing, the Company and
its Subsidiaries will not be party to any tax sharing or similar arrangement
with El Paso or any other Subsidiaries of El Paso (or make payments to El Paso
or any other Subsidiaries of El Paso of amounts intended to reimburse El Paso or
such other Subsidiaries for having paid any such Federal or state income taxes)
if the effect thereof would be to require the Company and its Subsidiaries to
make payments in respect of income taxes (or in respect of reimbursement for
such taxes) to El Paso or any of such other Subsidiaries in amounts the
cumulative sum of which exceeds the cumulative sum of income taxes that the
Company and its Subsidiaries would have paid in respect of Federal and state
income taxes if the Company and its Subsidiaries had at all times (including at
all times prior to the date hereof) filed a separate consolidated Federal income
tax return, with the Company as the "common parent" (with the meaning of Section
1504 of the Code), and taking into account all net operating loss carryforwards

Company and its Subsidiaries had they filed such a separate return.

            9.14 USE OF PROCEEDS. The Company will use the proceeds of the Loans
hereunder solely to finance the Acquisition, to provide working capital and for
other general corporate purposes of the Company and each of its Restricted

Owned Subsidiary, the Company will cause such new Restricted Subsidiary that is
a Wholly Owned Subsidiary to become a "Subsidiary Guarantor" (and, thereby, an
"Obligor") hereunder, to pledge and grant a security interest in its Property
pursuant to the Security Documents to the Administrative Agent for the benefit
of the Lenders, pursuant to one or more written instruments in form and
substance satisfactory to the Administrative Agent and to deliver such proof of

ensure that each of its Restricted Subsidiaries, other than the Exempted
Restricted Subsidiaries, is a Wholly Owned Subsidiary. In the event that any
additional shares of stock shall be issued by any Restricted Subsidiary, the
respective Obligor agrees forthwith to deliver to the Administrative Agent
pursuant to the Pledge and Security Agreement the certificates evidencing such
shares of stock, accompanied by undated stock powers executed in blank and to
take such other action as the Administrative Agent shall request to perfect the
security interest created therein pursuant to the Pledge and Security Agreement.

            (c) CERTAIN RESTRICTIONS. The Company will not permit any of its
Restricted Subsidiaries to enter into, after the date hereof, any indenture,

Company or (y) the distribution of any Dividend Payments except as

which the Company or such Restricted Subsidiary intends to use for substantially
the same purpose or purposes as the property sold or transferred; PROVIDED that
this Section 9.19 shall not prohibit a sale and leaseback transaction in respect
of any Property of the Company or any such Restricted Subsidiary, if and to the
extent the Company or such Restricted Subsidiary would be entitled to mortgage,
pledge, encumber, or create a lien, charge or security interest upon, such
Property pursuant to Section 9.06 hereof.

            Section 11. THE ADMINISTRATIVE AGENT.

            11.01 APPOINTMENT, POWERS AND IMMUNITIES. Each Lender hereby
appoints and authorizes the Administrative Agent to act as its agent hereunder
and under the other Loan Documents with such powers as are specifically
delegated to the Administrative Agent by the terms of this Agreement and of the
other Loan Documents, together with such other powers as are reasonably
incidental thereto. The Administrative Agent (which term as used in this
sentence and in Section 11.05 and the first sentence of Section 11.06 hereof
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 in the other Loan Documents, and shall not
      by reason of this Agreement or any other Loan Document be a trustee for
      any Lender;

            (b) shall not be responsible to the Lenders for any recitals,
      statements, representations or warranties contained in this Agreement or
      in any other Loan Document, or in any certificate or other document
      referred to or provided for in, or received by any of them under, this
      Agreement or any other Loan Document, or for the value, validity,
      effectiveness, genuineness, enforceability or sufficiency of this
      Agreement, any Note or any other Loan Document or any other document
      referred to or provided for herein or therein or for any failure by the
      Company or any other Person to perform any of its obligations hereunder or
      thereunder;
<PAGE>
                                      -86-

            (c) shall not, except to the extent expressly instructed by the
      Majority Lenders with respect to collateral security under the Security
      Documents, be required to initiate or conduct any litigation or collection
      proceedings hereunder or under any other Loan Document;

            (d) shall not be responsible for any action taken or omitted to be
      taken by it hereunder or under any other Loan Document or under any other
      document or instrument referred to or provided for herein or therein or in
      connection herewith or therewith, except for its own gross negligence or
      willful misconduct; and

            (e) shall have no liability or other obligation to the Company or
      any Lender in respect of any determination made or to be made by the
      Administrative Agent relating to the method used or to be used, any
      assumption made or to be made or any other matter relating to the
      computation of the Borrowing Base, the Threshold Amount or any component
      of any thereof, other than (i) to the extent practicable, to consult with
      the Lenders as to any such determination and (ii) to make any such
      determination in good faith and in a manner consistent with the express
      requirements of this Agreement.

The Administrative Agent 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. The Administrative Agent may
deem and treat the payee of a Note as the holder thereof for all purposes hereof
unless and until a notice of the assignment or transfer thereof shall have been
filed with the Administrative Agent, together with the consent of the Company to
such assignment or transfer (to the extent required by Section 12.06(b) hereof).

            11.02 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely upon any certification, notice or other communication
(including, without limitation, any thereof by telephone, telecopy, telegram or
cable) reasonably 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 upon advice
and statements of legal counsel, independent accountants and other experts
selected by the Administrative Agent. As to any matters not expressly provided
for by this Agreement or any other Loan Document, the Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder or thereunder in accordance with instructions given 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.

            11.03 DEFAULTS. Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has 
<PAGE>
                                      -87-

received notice from a Lender or the Company specifying such Default and stating
that such notice is a "Notice of Default". In the event that the Administrative
Agent receives such a notice of the occurrence of a Default, the Administrative
Agent shall give prompt notice thereof to the Lenders. The Administrative Agent
shall (subject to Section 11.07 hereof) take such action with respect to such
Default as shall be directed by the Majority Lenders, 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 interest of the Lenders except to the extent that this
Agreement expressly requires that such action be taken, or not be taken, only
with the consent or upon the authorization of the Majority Lenders or all of the
Lenders.

            11.04 RIGHTS AS A LENDER. With respect to its Commitment and the
Loans made by it, Chase (and any successor acting as Administrative 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 the Administrative Agent, and the term "Lender" or "Lenders" shall,
unless the context otherwise indicates, include the Administrative Agent in its
individual capacity. Chase (and any successor acting as Administrative Agent)
and its affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in and generally engage in any
kind of banking, trust or other business with the Obligors (and any of their
Subsidiaries or Affiliates) as if it were not acting as the Administrative
Agent, and Chase (and any such successor) and its affiliates may accept fees and
other consideration from the Obligors for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

            11.05 INDEMNIFICATION. The Lenders agree to indemnify the
Administrative Agent (to the extent not reimbursed under Section 12.03 hereof,
but without limiting the obligations of the Company under said Section 12.03,
and including in any event any payments under any indemnity that the
Administrative Agent is required to issue to any bank referred to in Section
4.02 of the Pledge and Security Agreement to which remittances in respect of
Accounts, as defined therein, are to be made) ratably in accordance with the
aggregate principal amount of the Loans held by the Lenders (or, if no Loans are
at the time outstanding, ratably in accordance with their respective
Commitments), for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever that may be imposed on, incurred by or asserted
against the Administrative Agent (including by any Lender) arising out of or by
reason of any investigation in or in any way relating to or arising out of this
Agreement or any other Loan Document or any other documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
(including, without limitation, the 
<PAGE>
                                      -88-

costs and expenses that the Company is obligated to pay under Section 12.03
hereof, and including also any payments under any indemnity that the
Administrative Agent is required to issue to any bank referred to in Section
4.02 of the Pledge and Security Agreement to which remittances in respect of
Accounts, as defined therein, are to be made, 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 the enforcement
of any of the terms hereof or thereof or of any such other documents, PROVIDED
that no Lender shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the party to be indemnified.

            11.06 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender agrees that it has, independently and without reliance on the
Administrative 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 that
it will, independently and without reliance upon the Administrative 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 under any other Loan
Document. The Administrative Agent shall not be required to keep itself informed
as to the performance or observance by any Obligor of this Agreement or any of
the other Loan Documents or any other document referred to or provided for
herein or therein or to inspect the Properties or books of the Company or any of
its Subsidiaries. Except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by the
Administrative Agent hereunder or under the Security Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Company or any of its Subsidiaries (or any of their
affiliates) that may come into the possession of the Administrative Agent or any
of its affiliates.

            11.07 FAILURE TO ACT. Except for action expressly required of the
Administrative Agent hereunder and under the other Loan Documents, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction from the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and expense
that may be incurred by it by reason of taking or continuing to take any such
action.

            11.08 RESIGNATION OR REMOVAL OF ADMINISTRATIVE AGENT. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Company, and the Administrative Agent may be removed at
any time with or without cause 
<PAGE>
                                      -89-

by the Majority Lenders. Upon any such resignation or removal, the Majority
Lenders shall have the right to appoint a successor Administrative Agent. If no
successor Administrative Agent shall have been so appointed by the Majority
Lenders and shall have accepted such appointment within 30 days after the
retiring Administrative Agent's giving of notice of resignation or the Majority
Lenders' removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, that shall be a bank that has an office in New York, New
York with a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations hereunder. After any
retiring Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Section 11 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 the Administrative Agent.

            11.09 CONSENTS UNDER OTHER LOAN DOCUMENTS.

            (a) Except as otherwise provided in Section 12.04 hereof with
respect to this Agreement, the Administrative Agent may, with the prior consent
of the Majority Lenders (but not otherwise), consent to any modification,
supplement or waiver under any of the Loan Documents, PROVIDED that,
notwithstanding any provision of Section 12.04, without the prior consent of
each Lender, the Administrative Agent shall not (except as provided herein or in
the Security Documents) release any collateral or otherwise terminate any Lien
under any Security Document providing for collateral security, agree to
additional obligations being secured by such collateral security (unless the
Lien for such additional obligations shall be junior to the Lien in favor of the
other obligations secured by such Security Document, in which event the
Administrative Agent may consent to such junior Lien provided that it obtains
the consent of the Majority Lenders thereto), alter the relative priorities of
the obligations entitled to the benefits of the Liens created under the Security
Documents.

            (b) Notwithstanding anything in Section 11.09(a) hereof to the
contrary, no consent of the Lenders or the Majority Lenders, as applicable,
shall be required, and the Administrative Agent is hereby authorized, to release
any Lien covering Property which is the subject of a disposition of Property
permitted hereunder or to which the Lenders or the Majority Lenders, as
applicable, have consented.

            (c) Notwithstanding anything in Section 11.09(a) hereof to the

Administrative Agent is hereby 
<PAGE>
                                      -90-

authorized, to release any Lien covering any portion of the Mortgaged Properties

recent determination of the Borrowing Base or Threshold Amount pursuant to
Section 2.11 hereof prior to the date of such request and (y) Properties
permitted to be sold, transferred or otherwise disposed of pursuant to Section
9.05 hereof. Upon the request and at the expense of the Company, the
Administrative Agent shall, not later than 30 days after the later of the date
(x) of such request and (y) on which the Administrative Agent receives all
documents and other evidence that the Administrative Agent may reasonably
request to determine whether such release is authorized under this Section
11.09(c), execute and deliver to the Company such documents as the Company shall
have delivered to the Administrative Agent to the extent the same are necessary
to effect the release of Property authorized to be released under this
paragraph.

            11.10 COLLATERAL SUB-AGENTS. Each Lender by its execution and
delivery of this Agreement agrees, as contemplated by Section 4.03 of the Pledge
and Security Agreement, that, in the event it shall hold any Permitted
Investments referred to therein, such Permitted Investments shall be held in the
name and under the control of such Lender, and such Lender shall hold such
Permitted Investments as a collateral sub-agent for the Administrative Agent
thereunder. The Company by its execution and delivery of this Agreement hereby
consents to the foregoing.

            Section 12. MISCELLANEOUS.

            12.01 WAIVER. No failure on the part of the Administrative Agent or
any Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under this Agreement or any Note shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under this Agreement or any Note 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.

            12.02 NOTICES. All notices and other communications provided for

interest contemplated by any Security Document or any other document referred to

liabilities, claims, damages or expenses incurred by any of them (including,
without limitation, any and all losses, liabilities, claims, damages or expenses
incurred by the Administrative Agent to any Lender, whether or not the
Administrative Agent or any Lender is a party thereto) arising out of or by
reason of any investigation or litigation or other proceedings (including any
threatened investigation or litigation or other proceedings) relating to the
Loans hereunder or any actual or proposed use by the Company or any of its

            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.

            12.06 ASSIGNMENTS AND PARTICIPATIONS.

            (a) No Obligor may assign any of its rights or obligations hereunder
or under the Notes without the prior consent of all of the Lenders and the
Administrative Agent.

            (b) Each Lender may assign any of its Loans, its Note, and its
Commitment (but only with the consent of the Company and the Administrative
Agent, such consents not to be unreasonably withheld); PROVIDED that

                      (i) no such consent by the Company or the Administrative
            Agent shall be required in the case of any assignment to another
            Lender or any assignment to an affiliate of the assigning Lender;
<PAGE>
                                      -94-

                     (ii) except to the extent the Company and the
            Administrative Agent shall otherwise consent, any such partial
            assignment (other than to another Lender) shall be in an amount at
            least equal to $5,000,000; and

                    (iii) each such assignment by a Lender of its Loans, Note or
            Commitment shall be made in such manner so that the same portion of
            its Loans, Note and Commitment is assigned to the respective
            assignee.

Upon execution and delivery by the assignee to the Company and the
Administrative Agent of an instrument in writing pursuant to which such assignee
agrees to become a "Lender" hereunder (if not already a Lender) having the
Commitment and Loans specified in such instrument, and upon consent thereto by
the Company and the Administrative Agent to the extent required above, the
assignee shall have, to the extent of such assignment (unless provided in such
assignment with the consent of the Company and the Administrative Agent), the
obligations, rights and benefits of a Lender hereunder holding the Commitment
and Loans (or portions thereof) assigned to it (in addition to the Commitment
and Loans, if any, theretofore held by such assignee) and the assigning Lender
shall, to the extent of such assignment, be released from the Commitment (or
portion thereof) so assigned. Upon each such assignment the assigning Lender
shall pay the Administrative Agent an assignment fee of $3,000.

            (c) A Lender may sell or agree to sell to one or more other Persons
(each a "PARTICIPANT") a participation in all or any part of any Loans held by
it, or in its Commitment, PROVIDED that such Participant shall not have any
rights or obligations under this Agreement or any Note or any other Loan
Document (the Participant's rights against such Lender in respect of such
participation to be those set forth in the agreements executed by such Lender in
favor of the Participant). All amounts payable by the Company to any Lender
under Section 5 hereof in respect of Loans held by it, and its Commitment, shall
be determined as if such Lender had not sold or agreed to sell any
participations in such Loans and Commitment, and as if such Lender were funding
each of such Loan and Commitment in the same way that it is funding the portion
of such Loan and Commitment in which no participations have been sold. In no
event shall a Lender that sells a participation agree with the Participant to
take or refrain from taking any action hereunder or under any other Loan
Document except that such Lender may agree with the Participant that it will
not, without the consent of the Participant, agree to (i) increase or extend the
term of such Lender's Commitment, (ii) extend the date fixed for the payment of
principal of or interest on the related Loan or Loans or any portion of any fee
hereunder payable to the Participant, (iii) reduce the amount of any such
payment of principal, (iv) reduce the rate at which interest is payable thereon,
or any fee hereunder payable to the Participant, to a level below the rate at
which the Participant is entitled to receive such interest or fee or (v) consent
to 
<PAGE>
                                      -95-

any modification, supplement or waiver hereof or of any of the other Loan
Documents to the extent that the same, under Section 11.09 or 12.04 hereof,
requires the consent of each Lender.

            (d) In addition to the assignments and participations permitted
under the foregoing provisions of this Section 12.06, any Lender may (without
notice to the Company, the Administrative Agent or any other Lender and without
payment of any fee) assign and pledge all or any portion of its Loans and its
Note to any Federal Reserve Bank as collateral security pursuant to Regulation A
and any Operating Circular issued by such Federal Reserve Bank, and such Loans
and Note shall be fully transferrable as provided therein. No such assignment
shall release the assigning Lender from its obligations hereunder.

            (e) A Lender may furnish any information concerning the Company or
any of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject, however, to Section 12.12(b) hereof.

            (f) Anything in this Section 12.06 to the contrary notwithstanding,
no Lender may assign or participate any interest in any Loan held by it
hereunder to the Company or any of its Affiliates or Subsidiaries without the
prior consent of each Lender.

            12.07 SURVIVAL. The obligations of the Company under Sections 5.01,
5.05, 5.06 and 12.03 hereof, the obligations of each Subsidiary Guarantor under
Section 6.03 hereof, and the obligations of the Lenders under Section 11.05
hereof, shall survive the repayment of the Loans and the termination of the
Commitments and, in the case of any Lender that may assign any interest in its
Commitment or Loans hereunder, shall survive the making of such assignment,
notwithstanding that such assigning Lender may cease to be a "Lender" hereunder.
In addition, each representation and warranty made, or deemed to be made by a
notice of any Loan, herein or pursuant hereto shall survive the making of such
representation and warranty, and no Lender shall be deemed to have waived, by
reason of making any Loan, any Default that may arise by reason of such
representation or warranty proving to have been false or misleading,
notwithstanding that such Lender or the Administrative Agent may have had notice
or knowledge or reason to believe that such representation or warranty was false
or misleading at the time such Loan was made.

            12.08 CAPTIONS. The table of contents and captions and section
headings appearing herein are included solely for convenience of reference and

            12.11 WAIVER OF JURY TRIAL. EACH OF THE OBLIGORS, THE ADMINISTRATIVE
AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED

ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE NOTES OR
THE TRANSACTIONS CONTEMPLATED HEREBY.

            12.12 TREATMENT OF CERTAIN INFORMATION; CONFIDENTIALITY. (a) The
Company acknowledges that from time to time financial advisory, investment
banking and other services may be offered or provided to the Company or one or

Company hereby authorizes each Lender to share any information delivered to such
Lender by the Company and its Subsidiaries pursuant to this Agreement, or in
connection with the decision of such Lender to enter into this Agreement, to any
such subsidiary or affiliate. Such authorization shall survive the repayment of
the Loans and the termination of the Commitments.

            (b) Each Lender and the Administrative Agent agrees (on behalf of
itself and each of its affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with their customary procedures for handling confidential information
of the same nature and in accordance with safe and sound banking practices, any

herein shall limit
<PAGE>
                                      -97-

the disclosure of any such information (i) to the extent required by statute,
rule, regulation or judicial process, (ii) to counsel for any of the Lenders or
the Administrative Agent, (iii) to regulatory personnel, auditors or
accountants, (iv) to the Administrative Agent or any other Lender (or to Chase

assignee or participant (or prospective assignee or participant) so long as such
assignee or participant (or prospective assignee or participant) first executes
and delivers to the respective Lender an acknowledgement to the effect that it
is bound by the provisions of this Section 12.12(b), which acknowledgement may
be included as part of the respective assignment or participation agreement
pursuant to which such assignee or participant acquires an interest in the Loans
hereunder).

            12.13 INTEREST. It is the intent of the Lenders and the Obligors in
the execution and performance of this Agreement and all matters incidental and
related hereto and the other Loan Documents or any agreement or instrument
executed in connection herewith or therewith or with any Indebtedness of the
Obligors to the Lenders to remain in strict compliance with all laws applicable
to the Lenders from time to time in effect, including, without limitation, usury
laws. In furtherance hereof, each Lender and the Obligors stipulate and agree
that none of the terms and provisions contained in or pertaining to this
Agreement or in the other Loan Documents or any other agreement or instrument
("OTHER AGREEMENT") executed in connection herewith or therewith or with any
Indebtedness of the Obligors to such Lender shall ever be construed to create a
contract to pay for the use, forbearance or detention of money with interest at
a rate or in an amount in excess of the Maximum Rate for such Lender or maximum
amount of interest permitted to be charged by such Lender under all laws in
effect and applicable to the Lender. For purposes of this Agreement and the Note
held by any Lender, "interest" shall include the aggregate of all amounts which

                          ENVIRONMENTAL MATTERS

            Shortly after Tenneco Ventures Corporation acquired West Delta 30,
in the course of repairs to a flowline the personnel representing Seneca
Resources, the Operator, noticed small sheens occurring coincidentally with
movement of divers working on the bottom. To the best of their knowledge, the
personnel believe that the source was a pre-existing condition of the mudline
and the previous owner, Shell, was notified accordingly by Seneca.

                               LITIGATION

PLAINS RESOURCES:
            A settlement has been reached in a lawsuit between Nicklos Drilling
Company and Plains Resources et. al. The lawsuit stemmed from costs incurred
when drillpipe was stuck in the Boagni #1 well, which led to a total loss of the
wellbore, necessitating a redrill of the well. Tenneco Ventures' share of the
settlement, which includes Joint Interest Billings and legal costs, is $230,000.
This settlement will be paid in January of 1997.

GECKO:
            In late 1995, three employees of a storage tank rental firm were
killed while cleaning out one of their tanks that had previously been used on a
location in which Tenneco Ventures had a working interest. The problem stemmed
from the employees having been exposed to Hydrogen Sulfide (H2S). According to
the operator of the well, Gecko Operating, the tank was tested prior to being
moved from a well site and found to be free of any H2S contamination. The source
of the H2S was traced to wash water utilized by the employees in their own yard.
The water had reportedly been taken from a different tank in their yard and
neither the source water nor the tank water was connected in any way to Gecko's
operations. Despite this background, Tenneco Ventures has received word that a
lawsuit is being filed against Gecko which could subsequently expose Tenneco
Ventures to the litigation. The potential liability of Tenneco Ventures, if any,
is unknown.

WEST DELTA 30:
            Tenneco Ventures has been advised that legal action is being pursued
by an individual as a result of injuries sustained while working at a platform
on the West Delta 30 block. The potential liability of Tenneco Ventures, if any,
is unknown.

MUSTANG ISLAND 847:
            In the Fall of 1995, a helicopter pilot under contract to OCS,
Tenneco Ventures' contract operator for the field, inadvertently stepped off
into a stairwell while tying down his aircraft on the B platform at Mustang
Island 847. The pilot reportedly received minor cuts, bruises and contusions,
was held overnight at a hospital for

<PAGE>
observation, and released. To Tenneco Ventures' knowledge, no claims have been
made or are pending relating to this incident which is being identified as the
only known injury sustained on a property operated by Tenneco Ventures.

WEST COTE BLANCHE BAY:
            Tenneco Ventures and Tenneco Gas Production Corporation ("TGPC")
have 7.19889% and 3.59890% working interests, respectively, in West Cote Blanche
Bay. In connection with those interests, Tenneco Ventures and TGPC are alleged
by Texaco Exploration and Production, Inc. ("Texaco") to owe a portion of $1.3
million, which represents total debt outstanding to Texaco from Benton Oil and
Gas Company of Louisiana, Tenneco Ventures and TGPC. Texaco has indicated that
it will pursue all available remedies to collect amounts owing. Management
believes that the likely exposure of Tenneco Ventures and TGPC does not exceed
$175,000, and efforts are underway with Texaco to resolve this dispute.

                        MATERIAL ADVERSE CHANGES


After December 31, 1995, the following series of transactions were entered into
by Tenneco Ventures Corporation and its Subsidiaries related to Michigan
activities.

CONTRIBUTION AGREEMENT
On March 29, 1996, a Contribution Agreement was executed among Hi P Limited
Partnership, Montana BC Limited Partnership, Dwain Immel, Manistee Gas Limited
Liability Company ("Manistee"), and Michigan Gas Fund I.

The agreement provided for the formation of Michigan Production Company, LLC
("MPC") and Michigan Energy Company, LLC ("MEC"). Debt owed by Manistee and
Basin Pipeline Company, LLC ("Basin") to Michigan Gas Fund I of, collectively,
approximately $18.7 million was contributed by Michigan Gas Fund I to MPC and
MEC in exchange for substantially all of the assets of Manistee and Basin.
Except for approximately $2.6 million, the obligations of Manistee and Basin to
repay such debt was forgiven. The $2.6 million of remaining obligation is
recourse only to certain property and equipment still owned by Manistee, with a
purchase option by MEC.

PARTICIPATION, OWNERSHIP, AND OPERATING AGREEMENT FOR WEST SHORE PROCESSING
COMPANY, LLC. ("WEST SHORE") On May 2, 1996, the referenced agreement was
executed providing for the creation of West Shore and the contribution of $16.7
million of capital by MarkWest Michigan, LLC ("MarkWest") to the activities of
West Shore and Basin. In exchange for the contribution, MarkWest earns up to a
60% ownership interest in West Shore and Basin. The capital is primarily
dedicated to building pipeline extensions and a processing plant. MPC and Oceana
Exploration Company, L.C. have also dedicated present and future gas reserves to
West Shore pursuant to a Gas Gathering Treating and Processing Agreement.

AMONG MPC AND MEC, AS THE BORROWERS AND BANK OF AMERICA ILLINOIS, AS THE LENDER

3.    ADMINISTRATION OF PLAN

      (a) The Plan shall be administered by the Committee. Except as provided in

Grants under the Plan; provided, however, that the members of the Committee
shall qualify to administer the Plan for purposes of Rule 16b-3 (and any other
applicable rule) promulgated under Section 16(b) of the Exchange Act to the
extent that the Corporation is subject to such rule. The

                                     3
<PAGE>
Committee may adopt its own rules of procedure, and action of a majority of the
members of the Committee taken at a meeting, or action taken without a meeting
by unanimous written consent, shall constitute action by the Committee. The
Committee shall have the power and authority to administer, construe and
interpret the Plan, to make rules for carrying it out and to make changes in
such rules. Any such interpretations, rules, and administration shall be
consistent with the basic purposes of the Plan.

      (b) The Committee may delegate to the Chief Executive Officer and to other
senior officers of the Corporation its duties under the Plan subject to such
conditions and limitations as the Committee shall prescribe except that only the
Committee may designate and make Grants to Participants who are subject to
Section 16 of the Exchange Act.

      (c) The Committee may employ attorneys, consultants, accountants,

the Plan or the Grants, and all members of the Committee shall be fully

Corporation or any of its Affiliates, and in such form and having such terms,
conditions and limitations as the Committee may determine. Grants may be granted
singly, in combination or in tandem. The terms, conditions and limitations of
each Grant under the Plan shall be set forth in a Grant Agreement, in a form
approved by the Committee, consistent, however, with the terms of the Plan;
provided, however, such Grant Agreement shall contain provisions dealing with
the treatment of Grants in the event of the termination, death or disability of
a Participant, and may also include provisions concerning the treatment of
Grants in the event of a Change of Control of Corporation.

                                     4
<PAGE>
5.    GRANTS

      From time to time, the Committee will determine the forms and amounts of
Grants for Participants. Such Grants may take the following forms in the
Committee's sole discretion:

      (a) INCENTIVE STOCK OPTIONS - These are stock options within the meaning
of Section 422 of the Internal Revenue Code of 1986, as amended ("Code"), to
purchase Common Stock. In addition to other restrictions contained in the Plan,
an option granted under this Paragraph 5(a), (i) may not be exercised more than
10 years after the date it is granted, (ii) may not have an option price less
than the Fair Market Value of Common Stock on the date the option is granted,
(iii) must otherwise comply with Code Section 422, and (iv) must be designated
as an "Incentive Stock Option" by the Committee. The maximum aggregate Fair
Market Value of Common Stock (determined at the time of each Grant) with respect
to which Incentive Stock Options are first exercisable with respect to any
Participant under this Plan and any Incentive Stock Options granted to the
Participant for such year under any plans of the Corporation or any Subsidiary
in any calendar year is $100,000. Payment of the option price shall be made in
accordance with the terms of Paragraph 6, the Grant Agreement, and of any
applicable guidelines of the Committee in effect at the time.

      (b) OTHER STOCK OPTIONS - These are options to purchase Common Stock which
are not designated by the Committee as "Incentive Stock Options". At the time of
the Grant the Committee shall determine, and shall include in the Grant
Agreement or other Plan rules, the option exercise period, the option price, and
such other conditions or restrictions on the grant or exercise of the option as
the Committee deems appropriate, which may include the requirement that the
grant of options is predicated on the acquisition of Purchase Shares under
Paragraph 5(e) by the Optionee. In addition to other restrictions contained in
the Plan, an option granted under this Paragraph 5(b), (i) may not be exercised
more than 10 years after the date it is granted and (ii) may not have an option
exercise price less than 50% of the Fair Market Value of Common Stock on the
date the option is granted, PROVIDED that options to purchase up to 575 shares
of Common Stock may be granted with an exercise price of $.01 per share. Payment
of the option price shall be made in accordance with the terms of Paragraph 6,
the Grant Agreement and of any applicable guidelines of the Committee in effect
at the time.

      (c) STOCK APPRECIATION RIGHTS - These are rights that on exercise entitle
the holder to receive the excess of (i) the Fair Market Value of a share of
Common Stock on the date of exercise over (ii) the Fair Market Value on the date
of Grant (the "base value") multiplied by

                                     5
<PAGE>
(iii) the number of rights exercised as determined by the Committee. Stock
Appreciation Rights granted under the Plan may, but need not be, granted in
conjunction with an Option under Paragraph 5(a) or 5(b). The Committee, in the
Grant Agreement or by other Plan rules, may impose such conditions or
restrictions on the exercise of Stock Appreciation Rights as it deems
appropriate, and may terminate, amend, or suspend such Stock Appreciation Rights
at any time. No Stock Appreciation Right granted under this Plan may be
exercised less than 6 months or more than 10 years after the date it is granted
except in the event of death or disability of a Participant. To the extent that
any Stock Appreciation Right that shall have become exercisable, but shall not
have been exercised or cancelled or, by reason of any termination of employment,
shall have become non-exercisable, it shall be deemed to have been exercised
automatically, without any notice of exercise, on the last day on which it is
exercisable, provided that any conditions or limitations on its exercise are
satisfied (other than (i) notice of exercise and (ii) exercise or election to
exercise during the period prescribed) and the Stock Appreciation Right shall
then have value. Such exercise shall be deemed to specify that the holder elects
to receive cash and that such exercise of a Stock Appreciation Right shall be
effective as of the time of automatic exercise.

      (d) RESTRICTED STOCK - Restricted Stock is Common Stock delivered to a
Participant with or without payment of consideration with restrictions or
conditions on the Participant's right to transfer or sell such stock; provided
that the price of any Restricted Stock delivered for consideration and not as
bonus stock may not be less than 50% of the Fair Market Value of Common Stock on
the date such Restricted Stock is granted or the price of such Restricted Stock
may be the par value. If a Participant irrevocably elects in writing in the
calendar year preceding a Grant of Restricted Stock, dividends paid on the
Restricted Stock granted may be paid in shares of Restricted Stock equal to the
cash dividend paid on Common Stock. The number of shares of Restricted Stock and
the restrictions or conditions on such shares shall be as the Committee
determines, in the Grant Agreement or by other Plan rules, and the certificate
for the Restricted Stock shall bear evidence of the restrictions or conditions.
No Restricted Stock may have a restriction period of less than 6 months, other
than in the case of death or disability.

      (e) PURCHASE STOCK - Purchase Stock refers to shares of Common Stock
offered to a Participant at such price as determined by the Committee, the
acquisition of which will make him eligible to receive under the Plan,
including, but not limited to, Other Stock Options; provided, however, that the
price of such Purchase Shares may not be less than 50% of the Fair Market Value
of the Common Stock on the date such shares of Purchase Stock are offered.

                                     6
<PAGE>
      (f) DIVIDEND EQUIVALENT RIGHTS - These are rights to receive cash payments
from the Corporation at the same time and in the same amount as any cash
dividends paid on an equal number of shares of Common Stock to shareholders of
record during the period such rights are effective. The Committee, in the Grant
Agreement or by other Plan rules, may impose such restrictions and conditions on
the Dividend Equivalent Rights, including the date such rights will terminate,
as it deems appropriate, and may terminate, amend, or suspend such Dividend
Equivalent Rights at any time.

      (g) PERFORMANCE UNITS - These are rights to receive at a specified future
date payment in cash of an amount equal to all or a portion of the value of a
unit granted by the Committee. At the time of the Grant, in the Grant Agreement
or by other Plan rules, the Committee must determine the base value of the unit,
the performance factors applicable to the determination of the ultimate payment
value of the unit and the period over which the Corporation's performance will
be measured. These factors must include a minimum performance standard for the
Corporation below which no payment will be made and a maximum performance level
above which no increased payment will be made. The term over which the
Corporation's performance will be measured shall be not less than six months.

      (h) PERFORMANCE SHARES - These are rights to receive at a specified future
date payment in cash or Common Stock, as determined by the Committee, of an
amount equal to all or a portion of the average Fair Market Value for all days
that the Common Stock is traded during the last forty-five (45) days of the
specified period of performance of a specified number of shares of Common Stock
at the end of a specified period based on the Corporation's performance during
the period. At the time of the Grant, the Committee, in the Grant Agreement or
by Plan rules, will determine the factors which will govern the portion of the
rights so payable and the period over which the Corporation's performance will
be measured. The factors will be based on the Corporation's performance and must
include a minimum performance standard for the Corporation below which no
payment will be made and a maximum performance level above which no increased
payment will be made. The term over which the Corporation's performance will be
measured shall be not less than six months. Performance Shares will be granted
for no consideration.

      (i) OTHER STOCK-BASED GRANTS - The Committee may make other Grants under
the Plan pursuant to which shares of Common Stock (which may, but need not, be
shares of Restricted Stock pursuant to Paragraph 5(d)) or other equity
securities of the Corporation are or may in the future be acquired, or Grants
denominated in stock units, including ones valued using measures other than
market value. Other Stock-Based Grants may be granted

                                     7
<PAGE>
with or without consideration; provided, however, that the price of any such
Grant made for consideration that provides for the acquisition of shares of
Common Stock or other equity securities of the Corporation may not be less than
50% of the Fair Market Value of the Common Stock or such other equity securities
on the date of grant of such Grant. Such Other Stock-Based Grants may be made
alone, in addition to or in tandem with any Grant of any type made under the
Plan and must be consistent with the purposes of the Plan.

6.    PAYMENT OF OPTION PRICE FOR STOCK OPTIONS

      The payment of the option price for all shares purchased pursuant to the
exercise of Stock Options shall be (w) by cash or check in full on the date of
exercise (such cash or check may be delivered on behalf of a Participant by a
stock broker designated by the Corporation to whom the Participant has submitted
an irrevocable notice of election, on forms approved by the Corporation, to sell
shares of Common Stock deliverable upon exercise of a Stock Option), (x) through
the delivery of shares of Common Stock having a Fair Market Value equal to the
full amount of the exercise price, (y) by the withholding by the Corporation
from the shares of Common Stock issuable upon any exercise of the option that
number of shares having a Fair Market Value equal to such exercise price
pursuant to a written election delivered to the Committee prior to the date of
exercise, or (z) by a combination of such methods. The Committee shall determine
acceptable methods for tendering Common Stock and may impose such limitations
and prohibitions on the use of Common Stock to exercise a Stock Option as it
deems appropriate.

7.    LIMITATIONS AND CONDITIONS

      (a) The number of Shares available for Grants under this Plan shall be
1,150 shares of the authorized Common Stock as of the effective date of the
Plan, subject to adjustment in accordance with Section 9 or 10 hereof. The
number of Shares subject to Grants under this Plan to any one Participant shall
not be more than 450 shares, subject to adjustment in accordance with Section 9
or 10 hereof. Unless restricted by applicable law, Shares related to Grants that
are forfeited, terminated, cancelled or expire unexercised, shall immediately
become available for Grants.

      (b) No Grants shall be made under the Plan beyond ten years after the
effective date of the Plan, but the terms of Grants made on or before the
expiration of the Plan may extend beyond such expiration. At the time a Grant is
made or amended or the terms or conditions of a Grant are changed, the Committee
may provide for limitations or conditions on such Grant.

                                     8
<PAGE>
      (c) Nothing contained herein shall affect the right of the Corporation to
terminate any Participant's employment at any time or for any reason.

      (d) Deferrals of Grant payouts may be provided for, at the sole discretion
of the Committee, in the Grant Agreements.

      (e) Except as otherwise prescribed by the Committee, the amounts of the
Grants for any employee of a Affiliate, along with interest, dividend, and other
expenses accrued on deferred Grants, shall be charged to the Participant's
employer during the period for which the Grant is made. If the Participant is
employed by more than one Affiliates or by both the Corporation and an Affiliate
during the period for which the Grant is made, the Participant's Grant and
related expenses will be allocated between the companies employing the
Participant in a manner prescribed by the Committee.

      (f) Other than as specifically provided with regard to the death of a
Participant, no benefit under the Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or
charge, and any attempt to do so shall be void. No such benefit shall, prior to
receipt thereof by the Participant, be in any manner liable for or subject to
the debts, contracts, liabilities, engagements, or torts of the Participant.

      (g) Participants shall not be, and shall not have any of the rights or
privileges of, stockholders of the Corporation in respect of any Shares
purchasable in connection with any Grant unless and until certificates
representing any such Shares have been issued by the Corporation to such
Participants.

      (h) No election as to benefits or exercise of Stock Options, Stock
Appreciation Rights, or other rights may be made during a Participant's lifetime
by anyone other than the Participant except by a legal representative appointed
for or by the Participant.

      (i) Absent express provisions to the contrary, any grant under this Plan
shall not be deemed compensation for purposes of computing benefits or
contributions under any retirement plan of the Corporation or its Subsidiaries
and shall not affect any benefits under any other benefit plan of any kind now
or subsequently in effect under which the availability or amount of benefits is
related to level of compensation. This Plan is not a "Retirement Plan" or
"Welfare Plan" under the Employee Retirement Income Security Act of 1974, as
amended.

                                     9
<PAGE>
      (j) Unless the Committee determines otherwise, no benefit or promise under
the Plan shall be secured by any specific assets of the Corporation or any of
its Subsidiaries, nor shall any assets of the Corporation or any of its
Subsidiaries be designated as attributable or allocated to the satisfaction of
the Corporation's obligations under the Plan.

8.    TRANSFERS AND LEAVES OF ABSENCE

      For purposes of the Plan, unless the Committee determines otherwise: (a) a
transfer of a Participant's employment without an intervening period of
separation among the Corporation and any Affiliate shall not be deemed a
termination of employment, and (b) a Participant who is granted in writing a
leave of absence shall be deemed to have remained in the employ of the
Corporation during such leave of absence.

9.    ADJUSTMENTS

      In the event of any change in the outstanding Common Stock by reason of a
stock split, spin-off, stock dividend, stock combination or reclassification,
recapitalization or merger, Change of Control or similar event, or as required
under any Grant Agreement, the Committee may adjust appropriately the number of
Shares subject to the Plan and available for or covered by Grants and Share
prices related to outstanding Grants and make such other revisions to
outstanding Grants as it deems are equitably required.

10.   MERGER, CONSOLIDATION, EXCHANGE,
      ACQUISITION, LIQUIDATION OR DISSOLUTION

      In its absolute discretion, and on such terms and conditions as it deems
appropriate, coincident with or after the grant of any Stock Option or any
Stock-Based Grant, the Committee may provide, with respect to the merger or
consolidation of the Corporation into another corporation, the exchange of all
or substantially all of the assets of the Corporation for the securities of
another corporation, a Change of Control or the recapitalization,
reclassification, liquidation or dissolution of the Corporation, either a) that
such Stock Option or Stock-Based Grant cannot be exercised after such event, in
which case the Committee shall also provide, either by the terms of such Stock
Option or Stock-Based Grant or by a resolution adopted prior to the occurrence
of such event, that for some period of time prior to such event, such Stock
Option or Stock-Based Grant shall be exercisable as to all shares subject
thereto which are exercisable or, by virtue of the event, become exercisable,
notwithstanding anything to the contrary herein (but subject to the provisions
of Paragraph 7(b)) and that, upon the occurrence of such event, such Stock
Option or Stock-Based Grant

                                     10
<PAGE>
shall terminate and be of no further force or effect; or b) that even if the
Stock Option or Stock-Based Grant shall remain exercisable after such event,
from and after such event, any such Stock Option or Stock-Based Grant shall be
exercisable only for the kind and amount of securities and/or other property, or
the cash equivalent thereof, receivable as a result of such event by the holder
of a number of shares of stock for which such Stock Option or Stock-Based Grant
could have been exercised immediately prior to such event.

            In addition, in the event of a Change of Control, the Committee may,
in its absolute discretion and on such terms and conditions as it deems
appropriate, provide, either by the terms of such Stock Option or Stock-Based
Grant or by a resolution adopted prior to the occurrence of the Change of
Control, that such Stock Option or Stock-Based Grant shall be exercisable as to
all or any portion of the shares subject thereto, notwithstanding anything to
the contrary herein (but subject to the provisions of Paragraph 7(b)).

11.   AMENDMENT AND TERMINATION

      The Committee shall have the authority to make such amendments to any
terms and conditions applicable to outstanding Grants as are consistent with
this Plan provided that, except for adjustments under Paragraph 9 or 10 hereof,
no such action shall modify such Grant in a manner adverse to the Participant
without the Participant's consent except as such modification is provided for or
contemplated in the terms of the Grant.

      The Board of Directors may amend, suspend or terminate the Plan except
that no such action, other than an action under Paragraph 9 or 10 hereof, may be
taken which would, without shareholder approval (but only if such approval is
necessary for exemption under Section 16(b) of the Exchange Act), increase the
aggregate number of Shares available for Grants under the Plan, decrease the
price of outstanding Options or Stock Appreciation Rights, change the
requirements relating to the Committee or extend the term of the Plan.

12.   WITHHOLDING TAXES

      The Corporation shall have the right to deduct from any cash payment made
under the Plan any federal, state or local income or other taxes required by law
to be withheld with respect to such payment. It shall be a condition to the
obligation of the Corporation to deliver shares upon the exercise of a Stock
Option or Stock Appreciation Right, upon payment of Performance units or shares,
upon delivery of Restricted Stock or upon exercise, settlement or payment of any
Other Stock-Based Grant that the Participant pay to the Corporation such amount
as may be requested by the Corporation for the purpose of

                                     11
<PAGE>
satisfying any liability for such withholding taxes. Any Grant Agreement may
provide that the Participant may elect, in accordance with any conditions set
forth in such Grant Agreement, to pay a portion or all of such withholding taxes
in shares of Common Stock.

13.   EFFECTIVE DATE AND TERMINATION DATES

      The Plan shall be effective on and as of the date of its approval by the
stockholders of the Corporation and shall terminate ten years later, subject to
earlier termination by the Board of Directors pursuant to Paragraph 11;
PROVIDED, HOWEVER, that any payment under the Plan which would constitute a
"parachute payment" under section 280G of the Code must be approved by a vote of
75% of the Corporation's stockholders to be effective.
