                                  THE COMPANY
 
     Lomak is an independent energy company engaged in oil and gas development,
exploration and acquisition primarily in three core areas: the Midcontinent,
Appalachia and the Gulf Coast. Over the past five years, the Company has
significantly increased its reserves and production through acquisitions and, to
a growing extent, development and exploration of its properties. On a pro forma
basis as of December 31, 1996, the Company had proved reserves of 644 Bcfe with
a Present Value of $974 million. On an Mcfe basis, the reserves were 63%
developed and 77% natural gas, with a reserve life in excess of 13 years.
Properties operated by the Company accounted for 94% of its pro forma Present
Value. After giving effect to the Cometra Acquisition, the Company also owns
over 2,000 miles of gas gathering systems and a gas processing plant in
proximity to its principal gas properties. On a pro forma basis for the nine
months ended September 30, 1996, the Company had revenues of $123 million and
EBITDA of $72 million.
 
     From 1991 through 1996, the Company has made 63 acquisitions, including the
Cometra Acquisition, for an aggregate purchase price of approximately $627
million and has spent $37 million on development and exploration activities.
These activities have added approximately 720 Bcfe at an average cost of $0.75
per Mcfe. As a result, the Company has achieved substantial growth since 1991:
 
     - Reserves increased from 20 Bcfe in 1991 to 644 Bcfe in 1996, a compound
       annual growth rate of 101%;
 
     - Production increased from 2 Bcfe in 1991 to 49 Bcfe in 1996, a compound
       annual growth rate of 88%;
 
     - EBITDA increased from $4 million in 1991 to $72 million for the nine
       months ended September 30, 1996; and
 
     - Net income increased from $427,000 in 1991 to $12 million for the nine
       months ended September 30, 1996.
 
     The Company emphasizes strict cost controls in all aspects of its business.
As a result, combined direct operating and administrative costs have been
reduced from $2.08 per Mcfe in 1991 to $0.90 per Mcfe for the first nine months
of 1996 on a pro forma basis. Consequently, while the average price realized by
the Company has not increased significantly over the last five years, operating
margins have increased from $0.61 per Mcfe in 1991 to $1.65 per Mcfe for the
first nine months of 1996 on a pro forma basis.
 
                            THE COMETRA ACQUISITION
 
     On December 31, 1996, the Company agreed to acquire oil and gas properties
located in West Texas, South Texas and the Gulf of Mexico (the "Cometra
Properties") from American Cometra, Inc. ("Cometra") for a purchase price of
$400 million, subject to adjustment (the "Cometra Acquisition"). The Cometra
Acquisition will increase the Company's proved reserves at December 31, 1996 by
68% to 644 Bcfe and increase its Present Value by 98% to $974 million. The
Cometra Properties, located primarily in the Company's core operating areas,
include 515 producing wells, 401 proven development projects and substantial
additional development and exploration potential on approximately 150,000 gross
acres (90,000 net acres). In addition, the Cometra Properties include 265 miles
of gas pipelines, a 25,000 Mcf/d gas processing plant and an above-market gas
contract with a major Texas gas utility covering approximately 30% of the
December 1996 production from the Cometra Properties.

                               BUSINESS STRATEGY
 
     The Company's objective is to maximize shareholder value through aggressive
growth in its reserves, production, cash flow and earnings through a balanced
program of development drilling and acquisitions, as well as a growing
exploration effort. Management believes that the Cometra Acquisition has
substantially enhanced the Company's ability to increase its production and
reserves through drilling activities. The Cometra Acquisition substantially
increased the Company's inventory of proven drilling locations and, to an even
greater degree, its exploration and exploitation drilling potential. Including
the Cometra Properties, the Company has over 1,100 proven recompletion and
development drilling projects. As a result of the Cometra Acquisition, the
Company believes that it can meet its growth objectives over the next several
years without the benefit of future acquisitions. The Company currently plans to
spend $160 million over the next three years on the further development and
exploration of its properties. Consequently, while acquisitions are expected to
continue to play an important role in the Company's future growth, the primary
emphasis will shift towards exploiting the potential of the Company's larger
property base.
 
     In order to most effectively implement its operating strategy, the Company
has concentrated its activities in selected geographic areas. In each core area,
the Company has established separate acquisition, engineering, geological,
operating and other technical expertise. The Company believes that this
geographic focus provides it with a competitive advantage in sourcing and
evaluating new business opportunities within these areas, as well as providing
economies of scale in developing and operating properties.
 
     Lomak believes the competitive strengths described below will greatly
enhance its ability to achieve its long-term goals and objectives.
 
     - Diversified, Long Lived Reserve Base: Lomak has compiled a diversified
       group of predictable, long lived properties. The Company's oil and gas
       reserves are attributable to 7,280 producing wells that have a reserve
       life index in excess of 13 years. The reserves are concentrated in seven
       basins and are geographically and geologically diversified.
 
     - Substantial Inventory of Development and Exploration Projects: Lomak has
       over 1,100 proven development projects and a substantial number of
       exploration and exploitation drilling projects located within core
       operating areas in which the Company has significant operating and
       technical expertise.
 
     - Successful Acquisition Record: The Company's primary strength has
       historically been to identify and acquire properties that have increased
       reserves, production, cash flow and earnings. Excluding the Cometra
       Acquisition, since 1991 the Company has completed 62 acquisitions for an
       aggregate purchase price of $252 million. These acquisitions have added
       reserves of approximately 422 Bcfe at an average acquisition cost of
       $0.60 per Mcfe.
 
     - Significant Operational Control: Lomak operates properties representing
       nearly 94% of its Present Value. This allows the Company to directly
       control operating and drilling costs and also allows it to dictate the
       timing of development and exploration activities.
 
     - High Operating Margins: The Company's low cost structure, coupled with
       the premium gas price it receives for a significant portion of its
       production, creates high operating margins. For the first nine months of
       1996, Lomak generated operating margins, after deducting direct operating
       and administrative costs, of $1.65 per Mcfe.
 
     - Experienced, Incentivized Management Team: The Company's board of
       directors, executive officers, technical staff and administrative
       personnel have considerable industry experience and will own,
       collectively, shares representing approximately 10% of the outstanding
       shares of Common Stock, after giving effect to the Cometra Acquisition
       and the Common Stock Offering. Over 80% of Lomak's employees either own,
       or hold options to acquire, shares of Common Stock.

                       FINANCING THE COMETRA ACQUISITION
 
     After adjustment for cash flow attributable to the Cometra Properties from
October 1, 1996 to funding, it is expected that the adjusted purchase price for
the Cometra Acquisition, based on a scheduled funding of February 14, 1997, will
be approximately $375 million, of which $30 million will consist of shares of
Common Stock to be issued to Cometra.
 
     The Company will finance the cash portion of the purchase price with $220
million of borrowings under a recently expanded bank credit facility (the
"Credit Facility") and the issuance to Cometra of a $125 million non-interest
bearing promissory note due March 31, 1997, which is secured by a bank letter of
credit. The promissory note will be repaid at maturity through borrowings under
the Credit Facility. The Credit Facility will enable the Company to obtain
revolving credit loans and issue letters of credit from time to time in an
aggregate amount not to exceed $400 million initially. Availability under the
Credit Facility will be reduced to $325 million 180 days after the funding of
the Cometra Acquisition, unless otherwise agreed to by the lenders. Upon
consummation of the Offerings, approximately $230.9 million will be outstanding
under the Credit Facility.
 
     The Company maintains its corporate headquarters at 500 Throckmorton
Street, Fort Worth, Texas 76102 and its telephone number is (817) 870-2601.

(a) Proved reserves and future net cash flows were estimated in accordance with
    the Commission's guidelines. Prices at December 31 in each of the years 1993
    through 1996 were used in the calculation of proved reserves and future net
    cash flows and were held constant through the periods of estimated
    production, except as otherwise provided by contract, in accordance with the
    Commission's guidelines.
(b) The reserve life index is calculated as proved reserves (on an Mcfe basis)
    divided by annual production.
(c) Finding costs are calculated as costs incurred divided by net reserve
    additions. The pro forma cost incurred for 1996 excludes $62 million
    attributable to unproved reserves ($0.16 per Mcfe impact). However, the pro
    forma cost incurred for 1996 includes the value attributable to an
    above-market gas contract of $38 million ($0.10 per Mcfe impact).
(d) Reserve replacement is calculated as net reserve additions divided by the
    Company's actual production for the period, both on an Mcfe basis.
(e) Operating margin is calculated as oil and gas sales less direct operating
    expense and general and administrative expense.

                                  RISK FACTORS
 
     Prior to making an investment decision, prospective investors should
carefully consider, together with the other information contained in this
Prospectus, the following risk factors:
 
VOLATILITY OF OIL AND GAS PRICES
 
     The Company's financial condition, operating results and future growth and
the carrying value of its oil and gas properties are substantially dependent on
prevailing prices of, and demand for, oil and gas. The Company's ability to
maintain or increase its borrowing capacity and to obtain additional capital on
attractive terms is also substantially dependent upon oil and gas prices.
Historically the markets for oil and gas have been volatile and are likely to
continue to be volatile in the future. Prices for oil and gas are subject to
large fluctuations in response to relatively minor changes in the supply of and
demand for oil and gas, market uncertainty and a variety of additional factors
beyond the control of the Company. These factors include weather conditions in
the United States and elsewhere, the economic conditions in the United States
and elsewhere, the actions of the Organization of Petroleum Exporting Countries
("OPEC"), governmental regulation, political stability in the Middle East and
elsewhere, the supply and demand of oil and gas, the price of foreign imports
and the availability and prices of alternate fuel sources. Any substantial and
extended decline in the price of oil or gas would have an adverse effect on the
Company's carrying value of its proved reserves, borrowing capacity, the
Company's ability to obtain additional capital, and its revenues, profitability
and cash flows from operations.
 
     Volatile oil and gas prices make it difficult to estimate the value of
producing properties for acquisition and often cause disruption in the market
for oil and gas producing properties, as buyers and sellers have difficulty
agreeing on such value. Price volatility also makes it difficult to budget for
and project the return on acquisitions and development and exploitation
projects.
 
UNCERTAINTY OF ESTIMATES OF RESERVES AND FUTURE NET REVENUES
 
     This Prospectus contains estimates of the Company's oil and gas reserves
and the future net revenues from those reserves which have been prepared by the
Company and certain independent petroleum consultants. Reserve engineering is a
subjective process of estimating the recovery from underground accumulations of
oil and gas that cannot be measured in an exact manner, and the accuracy of any
reserve estimate is a function of the quality of available data and of
engineering and geological interpretation and judgment. Estimates of
economically recoverable oil and gas reserves and of future net cash flows
necessarily depend upon a number of variable factors and assumptions, such as
historical production from the area compared with production from other
producing areas, the assumed effects of regulations by governmental agencies and
assumptions concerning future oil and 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. Because all
reserve estimates are to some degree speculative, the quantities of oil and gas
that are ultimately recovered, production and operation costs, the amount and
timing of future development expenditures and future oil and gas sales prices
may all vary from those assumed in these estimates and such variances may be
material. In addition, different reserve engineers may make different estimates
of reserve quantities and cash flows based upon the same available data.
 
     The present value of estimated future net cash flows referred to in this
Prospectus should not be construed as the current market value of the estimated
proved oil and gas reserves attributable to the Company's properties. In
accordance with applicable requirements of the Commission, the estimated
discounted future net cash flows from proved reserves are generally based on
prices and costs as of the date of the estimate, whereas actual future prices
and costs may be materially higher or lower. The calculation of the Present
Value of the Company's oil and gas reserves were based on prices on December 31,
1996. Average product prices at December 31, 1996 were $23.58 per barrel of oil
and $3.54 per Mcf of gas and pro forma average product prices at December 31,
1996 were $23.23 per barrel of oil and $3.99 per Mcf of gas, which prices were
substantially higher than historical prices used by the Company to calculate
Present Value in recent years. In addition, the Company's reserves may be
subject to downward or upward revision based upon
 
                                       11
<PAGE>   14
 
production history, results of future development, prevailing oil and gas prices
and other factors. See "Business -- Oil and Gas Reserves."
 
FINDING AND ACQUIRING ADDITIONAL RESERVES
 
     The Company's future success depends upon its ability to find or acquire
additional oil and gas reserves that are economically recoverable. Except to the
extent the Company conducts successful exploration or development activities or
acquires properties containing proved reserves, the proved reserves of the
Company will generally decline as they are produced. There can be no assurance
that the Company's planned development projects and acquisition activities will
result in significant additional reserves or that the Company will have success
drilling productive wells at economic returns. If prevailing oil and gas prices
were to increase significantly, the Company's finding costs to add new reserves
could increase. The drilling of oil and gas wells involves a high degree of
risk, especially the risk of dry holes or of wells that are not sufficiently
productive to provide an economic return on the capital expended to drill the
wells. The cost of drilling, completing and operating wells is uncertain, and
drilling or production may be curtailed or delayed as a result of many factors.
 
     The Company's business is capital intensive. To maintain its base of proved
oil and gas reserves, a significant amount of cash flow from operations must be
reinvested in property acquisitions, development or exploration activities. To
the extent cash flow from operations is reduced and external sources of capital
become limited or unavailable, the Company's ability to make the necessary
capital investments to maintain or expand its asset base would be impaired.
Without such investment, the Company's oil and gas reserves would decline.
 
DEVELOPMENT AND EXPLORATION RISKS
 
     The Company intends to increase its development and exploration activities.
Exploration drilling, and to a lesser extent development drilling, involve a
high degree of risk that no commercial production will be obtained or that the
production will be insufficient to recover drilling and completion costs. The
cost of drilling, completing and operating wells is uncertain. The Company's
drilling operations may be curtailed, delayed or canceled as a result of
numerous factors, including title problems, weather conditions, compliance with
governmental requirements and shortages or delays in the delivery of equipment.
Furthermore, completion of a well does not assure a profit on the investment or
a recovery of drilling, completion and operating costs. See
"Business -- Development Activities" and " -- Exploration Activities."
 
ACQUISITION RISKS
 
     The Company intends to continue acquiring oil and gas properties. It
generally is not feasible to review in detail every individual property involved
in an acquisition. Ordinarily, review efforts are focused on the higher-valued
properties. However, even a detailed review of all properties and records may
not reveal 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 are not always performed on every
well, and environmental problems, such as groundwater contamination, are not
necessarily observable even when an inspection is undertaken. See
"Business -- Acquisition Activities."
 
     The consummation of the Cometra Acquisition will substantially increase the
Company's reserves, cash flow and production. The Company's ability to achieve
any advantages from the Cometra Acquisition will depend in large part on
successfully integrating the Cometra Properties into the operations of the
Company. No assurances can be made that the Company will be able to achieve such
integration successfully.
 
EFFECTS OF LEVERAGE
 
     On a pro forma basis giving effect to the Cometra Acquisition and the
related financings, at September 30, 1996, the Company's outstanding
indebtedness would have been $393 million and the Company's ratio of total debt
to total capitalization would have been 64%. The Company's level of indebtedness
will have several important effects on its future operations, including (i) a
substantial portion of the Company's cash
 
                                       12
<PAGE>   15
 
flow from operations must be dedicated to the payment of interest on its
indebtedness and will not be available for other purposes, (ii) covenants
contained in the Company's debt obligations will require the Company to meet
certain financial tests, and other restrictions will limit its ability to borrow
additional funds or to dispose of assets and may affect the Company's
flexibility in planning for, and reacting to, changes in its businesses,
including possible acquisition activities and (iii) the Company's ability to
obtain additional financing in the future for working capital, capital
expenditures, acquisitions, general corporate purposes or other purposes may be
impaired. The Company's ability to meet its debt service obligations and to
reduce its total indebtedness will be dependent upon the Company's future
performance, which will be subject to oil and gas prices, the Company's level of
production, general economic conditions and to financial, business and other
factors affecting the operations of the Company, many of which are beyond its
control. There can be no assurance that the Company's future performance will
not be adversely affected by some or all of these factors.
 
CAPITAL AVAILABILITY
 
     The Company's strategy of acquiring and developing oil and gas properties
is dependent upon its ability to obtain financing for such acquisitions and
development projects. The Company expects to utilize the Credit Facility among
the Company and several banks (the "Banks") to borrow a portion of the funds
required for any given transaction or project. If funds under the Credit
Facility are not available to fund acquisition and development projects, the
Company would seek to obtain such financing from the sale of equity securities
or other debt financing. There can be no assurance that any such other financing
would be available on terms acceptable to the Company. Should sufficient capital
not be available, the Company may not be able to continue to implement its
strategy.
 
     The Credit Facility limits the amounts the Company may borrow to amounts,
determined by the Banks, in their sole discretion, based upon a variety of
factors including the discounted present value of the Company's estimated future
net cash flow from oil and gas production (the "Borrowing Base"). On a pro forma
basis, at January 15, 1997, the Borrowing Base would have been $400 million, of
which the Company would have had borrowings of $220 million outstanding. The
Borrowing Base will be reduced to $325 million 180 days after the funding of the
Cometra Acquisition, unless otherwise agreed to by the Banks. If oil or gas
prices decline below their current levels, the availability of funds and the
ability to pay outstanding amounts under the Credit Facility could be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition -- Liquidity and Capital Resources."
 
OPERATING HAZARDS AND UNINSURED RISKS; PRODUCTION CURTAILMENTS
 
     The oil and gas business involves a variety of operating risks, including,
but not limited to, unexpected formations or pressures, uncontrollable flows of
oil, gas, brine or well fluids into the environment (including groundwater
contamination), blowouts, cratering, fires, explosions, pipeline ruptures or
spills, pollution and other risks, any of which could result in personal
injuries, loss of life, damage to properties, environmental pollution,
suspension of operations and substantial losses. Although the Company carries
insurance which it believes is reasonable, it is not fully insured against all
risks. Losses and liabilities arising from uninsured or under-insured events
could have a material adverse effect on the financial condition and operations
of the Company.
 
     From time to time, due primarily to contract terms, pipeline interruptions
or weather conditions, the producing wells in which the Company owns an interest
have been subject to production curtailments. The curtailments vary from a few
days to several months. In most cases the Company is provided only limited
notice as to when production will be curtailed and the duration of such
curtailments. The Company is currently not curtailed on any of its production.
 
     Certain of the Cometra Properties are offshore operations in the Gulf of
Mexico which are subject to a variety of operating risks peculiar to the marine
environment, such as hurricanes or other adverse weather conditions, 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.
 
                                       13
<PAGE>   16
 
HEDGING RISKS
 
     The Company has currently hedged approximately 12% of its pro forma
production through April 1997. These hedges have in the past involved fixed
price arrangements and other price arrangements at a variety of prices, floors
and caps. The Company may in the future enter into oil and natural gas futures
contracts, options and swaps. The Company's hedging activities, while intended
to reduce the Company's sensitivity to changes in market prices of oil and gas,
are subject to a number of other risks. In addition, such transactions may
expose the Company to the risk of financial loss in certain circumstances,
including instances in which (i) production is less than expected, (ii) there is
a widening of price differentials between delivery points required by fixed
price delivery contracts to the extent they differ from those of the Company's
production, (iii) the Company's customers or the counterparties to its futures
contracts fail to purchase or deliver the contracted quantities of oil or
natural gas or (iv) a sudden, unexpected event materially impacts oil or natural
gas prices. Additionally, the fixed price sales and hedging contracts limit the
benefits the Company will realize if actual prices rise above the contract
prices. In the future, the Company may increase the percentage of its production
covered by hedging arrangements.
 
GAS CONTRACT RISK
 
     A significant portion of the Company's production is subject to fixed price
contracts. On a pro forma basis, approximately 47% of average gas production for
December 1996 was sold subject to fixed price sales contracts (including a
contract relating to the Cometra Properties described below). These fixed price
contracts are at prices ranging from $2.15 to $3.70 per Mcf. The fixed price
contracts with terms of less than one year, between one and five years and
greater than five years constitute approximately 31%, 65% and 4%, respectively,
of the volume sold under fixed price contracts. The fixed price sales contracts
limit the benefits the Company will realize if actual prices rise above the
contract prices.
 
     As part of the Cometra Acquisition, the Company acquired a gas sales
contract covering 20,000 acres currently producing approximately 20,000 Mcf/d.
The price paid pursuant to the contract was $3.70 per Mcf at December 31, 1996
(55% higher than average 1996 natural gas prices received by the Company) and
escalates at $0.05 per Mcf per annum. The contract is with a large gas utility
and expires in June 2000. This contract represents 14% of the Company's pro
forma December 1996 production on an Mcfe basis.
 
     The Company believes that these fixed price contracts are enforceable and
it has not received any notice or other indication from any of the
counterparties that they intend to cease performing any of their obligations
under these contracts. However, there can be no assurance that one or more of
these counterparties will not attempt to mitigate their obligations under these
contracts. If any of the purchasers under the contracts should be successful in
doing so, then the Company could be required to market its production on less
attractive terms, which could have a material adverse effect on the Company's
earnings and cash flow.
 
GAS GATHERING, PROCESSING AND MARKETING
 
     The Company's gas gathering, processing and marketing operations depend in
large part on the ability of the Company to contract with third party producers
to produce their gas, to obtain sufficient volumes of committed natural gas
reserves, to maintain throughput in the Company's processing plant at optimal
levels, to replace production from declining wells, to assess and respond to
changing market conditions in negotiating gas purchase and sale agreements and
to obtain satisfactory margins between the purchase price of its natural gas
supply and the sales price for such residual gas volumes and the natural gas
liquids processed. In addition, the Company's operations are subject to changes
in regulations relating to gathering and marketing of oil and gas. The inability
of the Company to attract new sources of third party natural gas or to promptly
respond to changing market conditions or regulations in connection with its
gathering, processing and marketing operations could materially adversely affect
the Company's results of operations.
 
LAWS AND REGULATIONS
 
     The Company's operations are affected by extensive regulation pursuant to
various federal, state and local laws and regulations relating to the
exploration for and development, production, gathering and marketing of
 
                                       14
<PAGE>   17
 
oil and gas. These regulations, among other things, control the rate of oil and
gas production, and control the amount of oil that may be imported. The
Company's operations are subject to numerous laws and regulations governing the
discharge of materials into the environment or otherwise relating to
environmental protection. These laws and regulations 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, and impose substantial liabilities for pollution which might
result from the Company's operations. Moreover, the recent trend toward stricter
standards in environmental legislation and regulation is likely to continue. For
instance, legislation has been proposed in Congress from time to time that would
reclassify certain crude oil and natural gas exploration and production wastes
as "hazardous wastes" which would make the reclassified wastes subject to much
more stringent handling, disposal and clean-up requirements. If such legislation
were to be enacted, it could have a significant impact on the operating costs of
the Company, as well as the oil and gas industry in general. Initiatives to
further regulate the disposal of crude oil and natural gas wastes are also
pending in certain states, and these various initiatives could have a similar
impact on the Company. The Company could incur substantial costs to comply with
environmental laws and regulations.
 
COMPETITION
 
     The Company encounters substantial competition in acquiring properties,
marketing oil and gas, securing equipment and personnel and operating its
properties. The competitors in acquisitions, development, exploration and
production include major oil companies, numerous independents, individual
proprietors and others. Many of these competitors have financial and other
resources which substantially exceed those of the Company. Therefore,
competitors may be able to pay more for desirable leases and to evaluate, bid
for and purchase a greater number of properties or prospects than the financial
or personnel resources of the Company will permit.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company depends, and will continue to depend in the foreseeable future,
on the services of its officers and key employees with extensive experience and
expertise in evaluating and analyzing producing oil and gas properties and
drilling prospects, maximizing production from oil and gas properties and
marketing oil and gas production, including John H. Pinkerton, the Company's
President and Chief Executive Officer. However, the Company does not have
employment contracts with any of its officers or key employees. The ability of
the Company to retain its officers and key employees is important to the
continued success and growth of the Company. The loss of key personnel could
have a material adverse effect on the Company. The Company does not maintain key
man life insurance on any of its officers or key employees. See "Management."
 
CERTAIN BUSINESS INTERESTS OF CHAIRMAN
 
     Thomas J. Edelman, Chairman of the Company, is also the President of Snyder
Oil Corporation ("SOCO"), an independent publicly traded oil and gas company,
and Chairman, President and Chief Executive Officer of Patina Oil & Gas Company
("Patina"), a publicly traded oil and gas company in which SOCO owns a majority
interest. The Company currently has no existing business relationships with
either SOCO or Patina, and neither SOCO nor Patina owns any of the Company's
securities. However, as a result of Mr. Edelman's position in these companies,
conflicts of interests may arise between them. The Company has, and it has been
advised that SOCO also has, board policies that require Mr. Edelman to give
notification of any potential conflicts that may arise between the Company and
SOCO. There can be no assurance, however, that the Company will not compete with
SOCO or Patina for the same acquisition or encounter other conflicts of
interest. See "Management" and "Certain Transactions."

                              COMETRA ACQUISITION
 
GENERAL
 
     On December 31, 1996, the Company agreed to acquire the Cometra Properties
for a purchase price of $400 million, subject to adjustment. As a result of the
Cometra Acquisition, the Company will significantly expand its inventory of both
development and exploration projects, increase its proved reserves at December
31, 1996 by 68% to 644 Bcfe and increase the Company's Present Value at December
31, 1996 by 98% to $974 million.
 
COMETRA PROPERTIES
 
     The Cometra Properties include 150,000 gross acres (90,000 net) located
within the Company's core operating areas in West Texas, South Texas and the
Gulf of Mexico. Netherland, Sewell & Associates, Inc., independent petroleum
consultants, estimated that at December 31, 1996, the Cometra Properties had
proved reserves of 202 Bcf of gas and 9.7 Mmbbls of oil with a Present Value of
$482 million. In December 1996, the Cometra Properties produced at a rate of 66
Mmcfe/d through 515 wells. The Cometra Properties include 265 miles of gas
pipelines and a 25,000 Mcf/d capacity gas processing plant.
 
     The West Texas properties are located in the Val Verde and Permian Basins
and account for 81% of the acquired reserves on a Present Value basis. The South
Texas/Gulf of Mexico properties account for 19% of the acquired reserves on a
Present Value basis. All of the Cometra Properties, except for the Gulf of
Mexico properties, are within the Company's existing core operating areas. As a
result, the Company expects to be able to quickly integrate the properties and
begin exploitation activities. To facilitate the integration, the Company plans
to offer positions to substantially all of Cometra's field and technical staff
associated with these properties.
 
     On a Present Value basis, 95% and 70%, respectively, of the West Texas and
South Texas/Gulf of Mexico properties are operated by the Company. The offshore
properties are operated by experienced third parties. Although the Company has
no definitive plans to do so at this time, the Company has previously announced
that it may elect to sell all or part of the Gulf of Mexico properties because
they are not located in the Company's core areas.

</TABLE>
 
     The West Texas properties consist of 450 wells on 99,000 gross acres
(70,000 net) located principally in the Val Verde and Permian Basins. The
Company will assume operations on 95% of the properties on a Present Value basis
and will operate the pipelines and gas processing plant. Existing production
ranges in depth from 3,000 to 7,000 feet. The Company has identified 365 proven
recompletion and development drilling projects in this area. In the Val Verde
Basin, the Company will benefit from a $3.70 per Mcf gas sales contract covering
20,000 acres currently producing approximately 20,000 Mcf/d. The contract is
with a large gas utility and expires in June 2000.
 
     The South Texas/Gulf of Mexico properties consist of 99 wells on 51,000
gross acres (20,000 net). The Company will assume operation of 70% of the
properties on a Present Value basis, primarily in South Texas. The Gulf of
Mexico properties include 14 producing wells on seven offshore platforms, all of
which are
 
                                       17
<PAGE>   20
 
operated by third parties, including British Borneo Exploration, Samedan Oil
Corporation and Seneca Resources. Total net daily production from the South
Texas/Gulf of Mexico properties is 22.3 Mmcfe. Onshore, production comes from
depths ranging from 1,000 to 12,000 feet, and has an estimated reserve life in
excess of seven years. In the Gulf of Mexico, production ranges in depth from
8,000 to 14,000 feet, while water depths vary from 50 to 220 feet. The Company
has identified a total of 36 development projects. Both shallower and deeper
horizons hold potential exploration opportunities, which the Company expects to
evaluate further with the assistance of 3-D seismic technology.
 
GAS PLANTS AND PIPELINES
 
     As part of the Cometra Acquisition, the Company will acquire 265 miles of
gas pipelines and a 25,000 Mcf/d capacity gas processing plant in the Permian
Basin. The gas plant, located outside Sterling, Texas, was constructed in 1995
and is currently processing gas, approximately 50% of which is attributable to
Company-operated wells, at the rate of 21,700 Mcf/d. The Company believes that
the plant's capacity could be expanded to 35,000 Mcf/d for an additional capital
expenditure of approximately $4.0 million.
 
PURCHASE AGREEMENTS
 
     The Company acquired the Cometra Properties pursuant to Purchase and Sale
Agreements dated December 31, 1996 (the "Purchase Agreements"). The Purchase
Agreements have an effective date of October 1, 1996 (the "Effective Date") and
the funding is expected to occur on February 14, 1997 (the "Funding Date").
 
     The Purchase Agreements provide for adjustments to the purchase price for,
among other things, (i) cash flow attributable to the Cometra Properties from
the Effective Date to the Funding Date, (ii) prepaid and unpaid ad valorem,
property, production, severance and similar taxes, (iii) overproduction or
underproduction of natural gas by Cometra as of the Funding Date, (iv)
reimbursement of overhead costs incurred by Cometra from the Effective Date to
the Funding Date, and (v) obligations of Cometra arising under any prepayment
arrangements prior to the Funding Date.
 
     If the Funding Date occurs on February 14, 1997, it is currently estimated
that the adjusted purchase price for the Cometra Properties will be $375
million. Of this amount, $220 million is payable in cash on the Funding Date
(including cash deposits previously made) and $30 million is payable through the
issuance to Cometra of a number of shares of Common Stock determined by dividing
$30 million by the average closing price of the Common Stock on the NYSE for the
five trading days immediately preceding February 14, 1997. The Company will
issue to Cometra a $125 million non-interest bearing promissory note due March
31, 1997, which is secured by a bank letter of credit, for the balance of the
adjusted purchase price. The Cometra Acquisition is subject to certain closing
conditions, including the expiration of any applicable waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.
 
                                 NOTES OFFERING
 
     Concurrently with the Common Stock Offering, the Company is offering $100
million aggregate principal amount of its Senior Subordinated Notes due 2007.
The closings of the Common Stock Offering and the Notes Offering are contingent
upon each other. Neither the Common Stock Offering nor the Notes Offering will
be completed until after the consummation of the Cometra Acquisition. The Notes
will be unconditionally guaranteed on an unsecured, senior subordinated basis,
by each of the Company's subsidiaries, provided that such guarantees will
terminate under certain circumstances. The Indenture for the Notes will contain
certain covenants, including, but not limited to, covenants with respect to the
following matters: (i) limitation on restricted payments; (ii) limitation on the
incurrence of indebtedness; (iii) limitation on issuances and sales of capital
stock by restricted subsidiaries; (iv) limitation on liens; (v) limitation on
disposition of proceeds of asset sales; (vi) limitation on transactions with
affiliates; (vii) limitation on dividends and other payment restrictions
affecting restricted subsidiaries; (viii) restrictions on mergers,
consolidations and transfers of assets; (ix) limitations on subsidiary
indebtedness and preferred stock; and (x) limitation on "layering" indebtedness.

                                USE OF PROCEEDS
 
     The net proceeds of the Common Stock Offering are estimated to be
approximately $79.3 million (assuming an offering price of $21 per share) and
the net proceeds of the Notes Offering are estimated to be approximately $96.7
million, after deducting underwriting discounts and estimated expenses. The
Company intends to use all of such net proceeds to repay certain indebtedness
incurred under the Credit Facility to fund a portion of the cash purchase price
for the Cometra Properties. See "Cometra Acquisition" and "Notes Offering." At
December 31, 1996, indebtedness under the Credit Facility, which expires in
January 2002, had a weighted average interest rate of 6.7%. For additional
information with respect to the interest rates, maturity and covenants related
to the Credit Facility, see "Description of Capital Stock and Indebtedness

    beginning of the last month of each calendar quarter and have been paid at
    the end of such calendar quarter.
 
     Dividends on the Common Stock were initiated in December 1995 and have been
paid in each successive quarter. The $2.03 Convertible Preferred Stock receives
cumulative quarterly dividends at the annual rate of $2.03 per share. If there
is any arrearage in dividends on the $2.03 Convertible Preferred Stock, the
Company may not pay dividends on the Common Stock. The Company has never been in
arrears in the payment of dividends on the $2.03 Convertible Preferred Stock.
See "Description of Capital Stock and Indebtedness."
 
     The payment of dividends is subject to declaration by the Board of
Directors and may depend upon earnings, capital expenditures and market factors
existing from time to time. The Credit Facility and the Indenture for the Notes
contain restrictions on the Company's ability to pay dividends on capital stock.
Under the most restrictive of these provisions, the Company could have paid
$          of dividends as of December 31, 1996.

Comparison of Nine Months Ended September 30, 1996 to Nine Months Ended
September 30, 1995
 
     The Company reported net income for the nine months ended September 30,
1996 of $8.1 million, a 198% increase over the same period in 1995. The increase
is the result of higher production levels and product prices.
 
     During the first nine months of 1996, oil and gas production volumes
increased 77% to 20.8 Bcfe, an average of 75.8 Mmcfe/d. Production revenues also
benefited from a 17% increase in the average price received per Mcfe of
production from $2.06 to $2.40. The average oil price increased 12% from $16.58
to $18.60 per barrel and average gas prices increased 28% from $1.71 to $2.19
per Mcf. As a result of a larger base of producing properties, operating
expenses increased 84% to $18.3 million. However, the operating cost per Mcfe
increased only slightly from $0.85 per Mcfe in the nine months ended September
30, 1995 to $0.88 per Mcfe in the 1996 period.
 
     Gas transportation and marketing revenues rose 77% in the first nine months
of 1996 to $4.1 million versus $2.3 million in the first nine months of 1995.
The higher revenues were due primarily to expanded marketing activities and
increased gas transportation revenues attributable to its larger pipeline
network. The increase in gas transportation and marketing expenses of 103%
reflects higher administration costs associated with the growth in gas
marketing.
 
     Field services revenues increased 47% in the first nine months of 1996 to
$10.5 million versus $7.1 million for the same period of 1995. The higher
revenues were due primarily to a larger base of operated properties. Field
services expenses increased 86% in the nine month period of 1996 versus 1995,
due to lower overall margins on the increasing revenue base. Exploration expense
rose 77% due to the Company's increased involvement in acreage acquisition,
seismic and exploratory drilling.
 
     General and administrative expenses increased 31% from $2.2 million for the
first nine months of 1995 to $2.9 million for the first nine months in 1996. On
a per Mcfe of production basis, general and administrative expenses decreased
from $0.19 in the 1995 period to $0.14 for the same period in 1996. Interest and
other income increased slightly primarily due to a higher level of property
sales. Interest expense increased 46% to $5.6 million as a result of the higher
average outstanding debt balance during the 1996 period due to the financing of
acquisitions in the 1996 period.
 
     Depletion, depreciation and amortization expense rose 69% as a result of
increased production volumes. As a percentage of oil and gas revenues,
depletion, depreciation and amortization expense improved to 33% in the 1996
period from 41% in the 1995 period as a result of increased product prices
during the 1996 period. The Company-wide depletion, depreciation and
amortization rate was $0.73 per Mcfe during both periods.
 
Comparison of 1995 to 1994
 
     The Company reported net income for the year ended December 31, 1995 of
$4.4 million, a 68% increase over 1994. This increase is the result of higher
production volumes attributable to acquisition and development activities.
 
     During the year, oil and gas production volumes increased 66% to 17.9 Bcfe,
an average of 49.2 Mmcfe/d. The increased revenues recognized from production
volumes were partially offset by an 8% decrease in the average price received
per Mcfe of production to $2.08. The average oil price increased 9% to $16.57
per barrel while average gas prices dropped 15% to $1.79 per Mcf. As a result of
the Company's larger base of producing properties and production, oil and gas
production expenses increased 49% to $14.9 million in 1995 versus $10.0 million
in 1994. However, the average operating cost per Mcfe produced decreased 11%
from $0.93 in 1994 to $0.83 in 1995.
 
     Gas transportation and marketing revenues increased 50% to $3.3 million
versus $2.2 million in 1994. Coupled with this increase in gas transportation
and marketing revenues was a 73% increase in associated expenses for the year.
These increases were due primarily to the acquisition of several pipeline
systems, as well as the expansion of the gas marketing efforts.
 
     Field services revenues increased 32% in 1995 to $10.1 million, despite the
September 1994 sale of virtually all well servicing and brine disposal assets in
Ohio. The decrease in activities due to this sale was more than offset by an
increase in well servicing and brine disposal activities in Oklahoma and well
operations
 
                                       30
<PAGE>   33
 
on acquired properties. Field services expenses increased 12% in 1995 to $6.5
million versus $5.8 million. The increase is attributed to the Oklahoma well
servicing and the cost of operating a larger base of properties. The increase in
well operating costs was offset to a great extent by the disposal in September
1994 of the Company's lower margin well servicing and brine hauling and disposal
businesses.
 
     Exploration expense increased 43% to $0.5 million due to the Company's
increased involvement in exploration projects. These costs include delay
rentals, seismic and exploratory drilling activities.
 
     General and administrative expenses increased 10% from $2.5 million in 1994
to $2.7 million in 1995. As a percentage of revenues, general and administrative
expenses were 5% in 1995 as compared to 7% in 1994. This improvement reflects
the spreading of administrative costs over a growing asset base.
 
     Interest and other income rose 180% primarily due to higher sales of
non-strategic properties. Interest expense increased 99% to $5.6 million as
compared to $2.8 million in 1994. This was primarily as a result of the higher
average outstanding debt balance during the year due to the financing of capital
expenditures. The average outstanding balances on the bank credit facility were
$42.0 million and $73.3 million for 1994 and 1995, respectively. The weighted
average interest rate on these borrowings was 6.3% and 7.3% for the years ended
December 31, 1994 and 1995, respectively.
 
     Depletion, depreciation and amortization increased 47% compared to 1994 as
a result of increased production volumes during the year. The increased
depletion of oil and gas properties was partially offset by the reduction of
depreciation of field services assets due to the 1994 sale of field service
assets. The Company-wide depletion, depreciation and amortization rate for 1995
was $0.83 per Mcfe versus $0.93 per Mcfe in 1994 due to the addition of
properties at lower than historical Mcfe costs.
 
Comparison of 1994 to 1993
 
     The Company reported net income for the year ended December 31, 1994 of
$2.6 million, an 88% increase over 1993 net income. This increase can be
attributed primarily to the realization of income from properties acquired in
the fourth quarter of 1993 and 1994, as well as the success of the 1994 drilling
program.
 
     During the year, oil and gas production volumes increased 141% to 10.8
Bcfe, an average of 29.7 Mmcfe per day. The increased revenues recognized from
production volumes were partially offset by a 9% decrease in the average price
received per Mcfe of production to $2.26. The average oil price decreased 5% to
$15.23 per barrel and average gas prices dropped 9% to $2.10 per Mcf. As a
result of the Company's larger base of producing properties and production, oil
and gas production expenses increased 126% to $10.0 million in 1994 versus $4.4
million in 1993. However, the average operating cost per Mcfe produced decreased
5% from $0.98 in 1993 to $0.93 in 1994.
 
     Gas transportation and marketing revenues rose almost 293% to $2.2 million
versus $0.6 million in 1993. Coupled with this increase in gas transportation
and marketing revenues was an increase in associated expenses for the year.
These increases were due primarily to the acquisition of several pipeline
systems in late 1993, as well as the expansion of the gas marketing efforts.
 
     Field services revenues increased 10% in 1994, despite the September 1994
sale of virtually all well servicing and brine hauling and disposal assets in
Ohio. The decrease was offset by a marked increase in well operating revenues
recognized on acquired properties. Field services expenses increased marginally
in 1994 to $5.8 million versus $5.7 million. The slight increase can be
attributed to the cost of operating a growing base of properties. The increase
in well operating costs was offset to a great extent by the disposal in
September 1994 of the Company's low-margin well servicing and brine hauling and
disposal businesses.
 
     Exploration expense increased 317% due to the Company's increased
involvement in drilling projects. The results of these costs can be seen in the
increase in production due partially to its 1994 drilling program.
 
     General and administrative expenses increased 21% from $2.0 million in 1993
to $2.5 million in 1994. As a percentage of revenues, general and administrative
expenses were 7% in 1994 as compared to 11% in 1993. This improvement reflects
the spreading of administrative costs over a growing asset base.
 
                                       31
<PAGE>   34
 
     Interest and other income rose 13% primarily due to a higher level of
non-strategic property sales. Interest expense increased 151% to $2.8 million as
compared to $1.1 million in 1993. This was a result of the higher average
outstanding debt balance during the year due to the financing of acquisitions
and rising interest rates.
 
     Depletion, depreciation and amortization increased 132% compared to 1993 as
a result of increased production volumes during the year. The increased
depletion of oil and gas properties was partially offset by the reduction of
depreciation of field services assets due to the September 1994 sale of field
service assets.
 
LIQUIDITY AND CAPITAL RESOURCES
 
General
 
     Working capital at September 30, 1996 was $9.0 million, representing a $4.6
million increase over the corresponding amount at December 31, 1995. At
September 30, 1996, the Company had $4.9 million in cash and total assets of
$284.2 million. During the nine months, long-term debt rose from $83.0 million
to $121.9 million.
 
     At September 30, 1996, capitalization totaled approximately $235 million,
of which approximately 48% was represented by stockholders' equity and 52% by
long-term debt. All of the long-term debt at that date was comprised of
borrowings under the $250 million revolving bank credit facility provided by the
Credit Facility of which $122 million was outstanding. The Credit Facility
currently provides for quarterly payments of interest with principal payments
beginning February 1999.
 
     In December 1996, the Company sold $55 million of 6% Convertible
Subordinated Debentures Due 2007 (the "Convertible Debentures") in a private
placement. Net proceeds to the Company of approximately $53 million were used,
together with internally generated funds, to reduce the amount outstanding under
the Credit Facility to $61 million at December 31, 1996. The Convertible
Debentures are redeemable by the Company after February 1, 2000 and are
convertible at the option of the holder into Common Stock at any time prior to
maturity or redemption at a conversion price of $19.25 per share, subject to
adjustment in certain circumstances.
 
Cash Flow
 
     The Company has three principal operating sources of cash: (i) sales of oil
and gas; (ii) revenues from field services and (iii) revenues from gas
transportation and marketing. The Company's cash flow is highly dependent upon
oil and gas prices. Decreases in the market price of oil or gas could result in
reductions of both cash flow and the borrowing base under the Credit Facility
which would result in decreased funds available, including funds intended for
planned capital expenditures.
 
     The Company's net cash provided by operations for the years ended December
31, 1993, 1994 and 1995 and for the nine months ended September 30, 1996 was
$4.3 million, $11.2 million, $16.6 million and $24.3 million, respectively. The
consistent increases in the Company's cash flow from operations can be
attributed to its growth primarily through acquisitions and development.
 
     The Company's net cash used in investing for the years ended December 31,
1993, 1994 and 1995 and for the nine months ended September 30, 1996 was $43.5
million, $29.5 million, $76.1 million and $66.8 million, respectively. Investing
activities for these periods are comprised primarily of additions to oil and gas
properties through acquisitions and development and, to a lesser extent,
exploitation and additions of field service assets. These uses of cash have
historically been partially offset through the Company's policy of divesting
those properties that it deems to be marginal or outside the Company's core
areas of operations. The Company's acquisition and development activities have
been financed through a combination of operating cash flow, bank borrowings and
capital raised through equity and debt offerings.
 
     The Company's net cash provided by financing for the years ended December
31, 1993, 1994 and 1995 and for the nine months ended September 30, 1996 was
$38.9 million, $21.2 million, $57.7 million and $44.3 million, respectively.
Sources of financing used by the Company have been primarily borrowings under
its Credit Facility and capital raised through equity and debt offerings.

Capital Requirements
 
     For 1995, the Company incurred capital expenditures for development and
exploration activities of $10.0 million and $0.2 million, respectively. In the
first nine months of 1996, $8.7 million and $0.5 million of expenses were
incurred for development activities and exploration activities, respectively.
Although these expenditures are principally discretionary, the Company is
currently projecting that it will spend approximately $160 million on
development, exploitation and exploration activities, which includes
approximately $45 million on exploitation and exploration expenditures through
1999. Internally generated funds are expected to be sufficient to fund
development and exploration expenditures. See "Business -- Development
Activities" and "-- Exploration Activities."
 
Credit Facility
 
     In connection with the financing of the Cometra Acquisition, the Company
and its subsidiaries will expand the existing credit facility with the bank
lenders. The Credit Facility will enable the Company to obtain revolving credit
loans and to issue letters of credit for the account of the Company from time to
time in an aggregate amount not to exceed $400 million (of which not more than
$125 million may be represented by letters of credit). The Borrowing Base, which
will initially be $400 million under the expanded facility, will be reduced to
$325 million 180 days after the funding of the Cometra Acquisition, unless
otherwise agreed by the lenders. The Borrowing Base is subject to semi-annual
determination and is calculated based upon a variety of factors, including the
discounted present value of estimated future net cash flow from oil and gas
production.
 
     The Company will be required to make a mandatory prepayment of all amounts
outstanding under the Credit Facility in excess of $325 million 180 days after
the funding of the Cometra Acquisition. At the Company's option, loans may be
prepaid, and revolving credit commitments may be reduced, in whole or in part at
any time in certain minimum amounts.
 
     At the Company's option, the applicable interest rates per annum will be
either LIBOR plus a margin ranging from 0.625% to 1.125% or the Alternate Base
Rate (as defined) plus a margin ranging from 0% to 0.25%. The Alternate Base
Rate is the highest of (a) the agent banks' reference rate, (b) the secondary
market rate for certificates of deposit (adjusted for maximum statutory reserve
requirements) plus 1.0% and (c) the federal funds effective rate plus 0.5%.
Until the occurrence of the Trigger Event (as defined below), the interest rate
margins will be increased by 50 basis points prior to March 31, 1997 and 100
basis points thereafter.
 
     The obligations of the Company under the Credit Facility will be
unconditionally and irrevocably guaranteed by each of the Company's direct and
indirect domestic subsidiaries (collectively, the "Subsidiary Guarantors"). In
addition, the Credit Facility will be secured by first priority security
interests in (i) existing mortgaged oil and gas properties of the Company and
the Cometra Properties, (ii) all accounts receivable, inventory and intangibles
of the Company and the Subsidiary Guarantors, and (iii) all of the capital stock
of the Company's direct or indirect subsidiaries. Substantially all of the
assets of the Company will be pledged as collateral if, 90 days after the
funding of the Cometra Acquisition, the Borrowing Base and amounts outstanding
under the Credit Facility have not been reduced to $325 million. Such additional
security interests will be released upon the (i) reduction of the amounts
outstanding under the Credit Facility to $325 million (or the then determined
Borrowing Base) and (ii) issuance of $75 million of Common Stock and/or the sale
of Company assets in excess of the Borrowing Base value attributable to such
assets as agreed by the lenders (the "Trigger Event").
 
     Immediately following the Cometra Acquisition, the Company expects that
approximately $385 million will be outstanding (including $125 million of then
outstanding letters of credit to secure the promissory note issued to Cometra as
part of the purchase price in the Cometra Acquisition) under the Credit
Facility. Upon consummation of the Offerings, approximately $230.9 million will
be outstanding under the Credit Facility. Accordingly, the Company believes that
a Trigger Event will occur upon completion of the Offerings.

Hedging Activities
 
     Periodically, the Company enters into futures, option and swap contracts to
reduce the effects of fluctuations in crude oil and natural gas prices. At
September 30, 1996, the Company had open contracts for oil and gas price swaps
of 280,000 barrels of oil and 586,000 Mcf of gas. These swap contracts are
designed to set average prices of $23.09 per barrel and $1.98 per Mcf. While
these transactions have no carrying value, the Company's mark-to-market exposure
under these contracts at September 30, 1996 was a net loss of $129,000. These
contracts expire monthly through March 1997. In October 1996, the Company
entered into swap contracts for an additional 250,000 barrels of oil at an
average price per barrel of $22.86. These contracts expire monthly through April
1997. The gains or losses on the Company's hedging transactions is determined as
the difference between the contract price and a reference price, generally
closing prices on the New York Mercantile Exchange. The resulting transaction
gains and loses are determined monthly and are included in net income for the
contract month as an adjustment to oil and gas revenue. Net gains relating to
these derivatives for the nine months ended September 30, 1996 approximated
$29,700.

                                    BUSINESS
 
GENERAL
 
     Lomak is an independent energy company engaged in oil and gas development,
exploration and acquisition primarily in three core areas: the Midcontinent,
Appalachia and the Gulf Coast. Over the past five years, the Company has
significantly increased its reserves and production through acquisitions and, to
a growing extent, development and exploration of its properties. On a pro forma
basis as of December 31, 1996, the Company had proved reserves of 644 Bcfe with
a Present Value of $974 million. On an Mcfe basis, the reserves were 63%
developed and 77% natural gas, with a reserve life in excess of 13 years.
Properties operated by the Company accounted for 94% of its pro forma Present
Value. After giving effect to the Cometra Acquisition, the Company also owns
over 2,000 miles of gas gathering systems and a gas processing plant in
proximity to its principal gas properties. On a pro forma basis for the nine
months ended September 30, 1996, the Company had revenues of $123 million and
EBITDA of $72 million.
 
     From 1991 through 1996, the Company has made 63 acquisitions, including the
Cometra Acquisition, for an aggregate purchase price of approximately $627
million and has spent $37 million on development and exploration activities.
These activities have added approximately 720 Bcfe at an average cost of $0.75
per Mcfe. As a result, the Company has achieved substantial growth since 1991:
 
     - Reserves increased from 20 Bcfe in 1991 to 644 Bcfe in 1996, a compound
       annual growth rate of 101%;
 
     - Production increased from 2 Bcfe in 1991 to 49 Bcfe in 1996, a compound
       annual growth rate of 88%;
 
     - EBITDA increased from $4 million in 1991 to $72 million for the nine
       months ended September 30, 1996; and
 
     - Net income increased from $427,000 in 1991 to $12 million for the nine
       months ended September 30, 1996.
 
     The Company emphasizes strict cost controls in all aspects of its business.
As a result, combined direct operating and administrative costs have been
reduced from $2.08 per Mcfe in 1991 to $0.90 per Mcfe for the first nine months
of 1996 on a pro forma basis. Consequently, while the average price realized by
the Company has not increased significantly over the last five years, operating
margins have increased from $0.61 per Mcfe in 1991 to $1.65 per Mcfe for the
first nine months of 1996 on a pro forma basis.
 
BUSINESS STRATEGY
 
     The Company's objective is to maximize shareholder value through aggressive
growth in its reserves, production, cash flow and earnings through a balanced
program of development drilling and acquisitions, as well as a growing
exploration effort. Management believes that the Cometra Acquisition has
substantially enhanced the Company's ability to increase its production and
reserves through drilling activities. The Cometra Acquisition substantially
increased the Company's inventory of proven drilling locations and, to an even
greater degree, its exploration and exploitation drilling potential. Including
the Cometra Properties, the Company has over 1,100 proven recompletion and
development drilling locations. As a result of the Cometra Acquisition, the
Company believes that it can meet its growth objectives over the next several
years without the benefit of future acquisitions. The Company currently plans to
spend $160 million over the next three years on the further development and
exploration of its properties. Consequently, while acquisitions are expected to
continue to play an important role in the Company's future growth, the primary
emphasis will shift towards exploiting the potential of the Company's larger
property base.
 
     In order to most effectively implement its operating strategy, the Company
has concentrated its activities in selected geographic areas. In each core area,
the Company has established separate acquisition, engineering, geological,
operating and other technical expertise. The Company believes that this
geographic focus provides it with a competitive advantage in sourcing and
evaluating new business opportunities within these areas, as well as providing
economies of scale in developing and operating properties.
 
                                       35
<PAGE>   38
 
     Lomak believes the competitive strengths described below will greatly
enhance its ability to achieve its long-term goals and objectives.
 
     - Diversified, Long Lived Reserve Base:  Lomak has compiled a diversified
       group of predictable, long lived properties. The Company's oil and gas
       reserves are attributable to 7,280 producing wells that have a reserve
       life index in excess of 13 years. The reserves are concentrated in seven
       basins and are geographically and geologically diversified.
 
     - Substantial Inventory of Development and Exploration Projects:  Lomak has
       over 1,100 proven development projects and a substantial number of
       exploration and exploitation drilling projects located within core
       operating areas in which the Company has significant operating and
       technical expertise.
 
     - Successful Acquisition Record:  The Company's primary strength has
       historically been to identify and acquire properties that have increased
       reserves, production, cash flow and earnings. Excluding the Cometra
       Acquisition, since 1991 the Company has completed 62 acquisitions for an
       aggregate purchase price of $252 million. These acquisitions have added
       reserves of approximately 422 Bcfe at an average acquisition cost of
       $0.60 per Mcfe.
 
     - Significant Operational Control:  Lomak operates properties representing
       nearly 94% of its Present Value. This allows the Company to directly
       control operating and drilling costs and also allows it to dictate the
       timing of development and exploration activities.
 
     - High Operating Margins:  The Company's low cost structure, coupled with
       the premium gas price it receives for a significant portion of its
       production, creates high operating margins. For the first nine months of
       1996, Lomak generated operating margins, after deducting direct operating
       and administrative costs, of $1.65 per Mcfe.
 
     - Experienced, Incentivized Management Team:  The Company's board of
       directors, executive officers, technical staff and administrative
       personnel have considerable industry experience and will own,
       collectively, shares representing approximately 10% of the outstanding
       shares of Common Stock, after giving effect to the Cometra Acquisition
       and the Common Stock Offering. Over 80% of Lomak's employees either own,
       or hold options to acquire, shares of Common Stock.
 
DEVELOPMENT ACTIVITIES
 
     The Company's development activities include recompletions of existing
wells, infield drilling and installation of secondary recovery projects.
Development projects are generated within core operating areas where the Company
has significant operational and technical expertise. Currently, as described
below, the Company has 1,163 proven development projects in inventory. These
projects are geographically diverse, vary between oil and gas and are balanced
with regard to risk. The following table sets forth information pertaining to
the Company's proven development inventory at December 31, 1996.

     The Company currently anticipates that it will initiate 175 to 200
development projects in 1997. Assuming that 200 projects are initiated per year,
the Company currently has more than a five year inventory of proven development
projects. Lomak expects to spend approximately $115 million over the next three
years for development.

     The Company has a large inventory of moderate risk/moderate reward
exploitation drilling opportunities, as well as higher risk/higher reward
exploration projects. Lomak has identified 267 exploitation drilling projects on
the Cometra Properties, principally consisting of step-out drilling from
existing proved or proved undeveloped locations. In addition, the Company has
identified numerous other exploitation drilling opportunities within its
existing properties. Current exploration projects target deeper horizons within
existing Company-operated fields, as well as establishing new fields in
exploration trend areas in which Lomak's technical staff has experience. The
Company has not previously, and does not currently, plan to participate in
wildcat exploratory drilling outside its core operating areas.
 
     Lomak's strategy is based on limiting its risk by allocating no more than
10% of its cash flow to higher risk exploration activities and by participating
in a variety of projects with differing characteristics. The Company's existing
inventory of exploration projects and leads varies in risk and reward based on
their depth, location and geology. A significant portion of the existing, as
well as future, exploration projects will be enhanced by use of advanced
technology including 3-D seismic and improved completion techniques.
 
     In each of its core operating areas, the Company's geological and
geophysical staff generate both exploitation and exploration projects with the
assistance of the Company's reservoir engineers, landmen and production
engineers. The Company currently estimates that it will spend $25 million on
exploitation activities and $20 million on exploration activities over the next
three years. Existing exploitation and exploration project inventory is
described below.
 
     Midcontinent.  In the Midcontinent region, exploitation and exploration
projects are located on both the Company's existing properties as well as the
Cometra Properties. Exploitation projects include 86 step-out drilling locations
on unproved leasehold acreage adjacent to the Company's production in the
Sterling area of the Permian Basin as well as 134 stepout locations primarily in
the Oakridge and Francis Hill Fields in the Val Verde Basin. In the Big Lake
area of the Permian Basin, the Company is conducting an analysis to determine
the potential for recovery of additional reserves through increased density
drilling. Based on the initial results of the study, the Company believes there
is potential for 200 economic drill sites on its Big Lake area acreage.
 
     Current exploration projects include deeper drilling to the Ellenburger and
Fussleman formations in the Permian and Val Verde Basins. Several projects
targeting the Red Fork, Morrow and Hunton formations are in various stages of
development in the Anadarko Basin. In the San Juan Basin, the Company's acreage
holds exploration potential for production from the Pictured Cliffs, Gallup and
Dakota formations.
 
     Gulf Coast.  In the Gulf Coast region exploitation and exploration projects
have been identified on both the Company's existing properties as well as the
Cometra Properties. Exploitation projects include 34 step-out drilling locations
for the Yegua and Frio formations in South Texas. Deeper, higher risk
exploratory projects have been generated in South Texas targeting the Wilcox and
Vicksburg formations. On the offshore properties, 10 exploitation and
exploration projects have been identified to the Lenticulina and Marginulina
sands. There are four exploration projects targeting the Taylor sand of the
Cotton Valley formation in East Texas.
 
     Appalachia.  In the Appalachian region, the Company has identified
approximately 100 step-out drilling projects on existing leasehold acreage. In
addition, the Company has identified several hundred additional potential
locations near Company-owned gathering systems on acreage the Company believes
will be available for leasing in the future. The Company believes that the
location of its pipelines will provide it with a competitive advantage in
leasing this acreage, which is currently unleased. These locations target the
blanket Clinton and Medina sandstones. Exploration activity in Appalachia
centers around the drilling of deeper formations from leasehold acreage
generally being held by existing production from shallower production. The
targeted formations are in the Knox Sequence trend, which includes the Rose Run,
Beekmantown and Trempealeau. Lomak currently owns leasehold aggregating over
250,000 net acres in the Knox Sequence trend
 
                                       37

area. With the assistance of higher quality 2-D seismic as well as 3-D seismic,
Lomak believes the Knox Sequence trend area could generate substantial reserves
over the next five years.
 
ACQUISITION ACTIVITIES
 
     The Company seeks to acquire properties that are expected to be immediately
accretive to cash flow and earnings and provide long-term growth in reserves and
production. The Company focuses on acquisitions that generally meet the
following criteria.
 
     - Location:  The Company targets potential acquisitions located in its core
       operating areas which typically contain many small operators and where
       the major oil companies are less active.
 
     - Operating Efficiency:  The Company targets potential acquisitions in
       which it believes direct operating cost reductions and administrative
       cost efficiencies can be achieved.
 
     - Potential for Increasing Reserves:  The Company pursues properties that
       it believes have the potential for increased reserves and production
       through development and exploration activities.
 
     - Potential for Incremental Purchases:  The Company seeks acquisitions
       where opportunities to purchase additional interests in the same or
       adjoining properties exist.
 
     - Complex Transactions:  The Company often pursues transactions which are
       more complex as a result of ownership issues or financial structure as it
       believes such transactions will attract fewer potential buyers.
 
     The following table sets forth information pertaining to acquisitions
completed during the period January 1, 1991 through December 31, 1996 (including
the Cometra Acquisition):

     In connection with the evaluation of its reserves, the Company has engaged
the following independent petroleum consultants: Netherland, Sewell &
Associates, Inc. (Cometra Properties), Wright & Company, Inc. (Appalachia), H.J.
Gruy and Associates, Inc. (Midcontinent and Gulf Coast), Huddleston & Co., Inc.
(Midcontinent) and Clay, Holt & Klammer (Appalachia). These engineers have been
employed primarily based on geographic expertise as well as their history in
engineering certain of the acquired properties. At December 31, 1996,
approximately 96% of the proved reserves set forth above were evaluated by
independent petroleum consultants, while the remainder were evaluated by the
Company's engineering staff. All estimates of oil and gas reserves are subject
to significant uncertainty. See "Risk Factors -- Uncertainty of Estimates of
Reserves and Future Net Revenues."
 
     The following table sets forth on a pro forma basis at December 31, 1996
the estimated future net cash flow from and the present value of the proved
reserves. Future net cash flow represents future gross cash flow from the
production and sale of proved reserves, net of production costs (including
production taxes, ad valorem taxes and operating expenses) and future
development costs. Such calculations, which are prepared in accordance with the
Statement of Financial Accounting Standards No. 69 "Disclosures about Oil and
Gas Producing Activities" are based on constant cost and price factors. Average
product prices at December 31, 1996 were $23.58 per barrel of oil and $3.54 per
Mcf of gas and pro forma average product prices at December 31, 1996 were $23.23
per barrel of oil and $3.99 per Mcf of gas. These prices were substantially
higher than historical prices used by the Company to calculate Present Value in
recent years. A decline in prices relative to year end 1996 would cause a
substantial decline in Present Value. For example, a $0.10 decline in gas
prices, holding all other variables constant, would decrease Present Value by
1.9% or
 
                                       41
<PAGE>   44
 
$18.5 million and a $1.00 decline in oil and NGL prices world decrease Present
Value by 1.3% or $12.1 million. Furthermore, there can be no assurance that the
proved reserves will be developed within the periods indicated and it is likely
that actual prices received in the future will vary from those used in deriving
this information. There are numerous uncertainties inherent in estimating
reserves and related information and different reservoir engineers often arrive
at different estimates for the same properties.

GAS GATHERING AND PROCESSING
 
     The Company's natural gas gathering and processing assets are primarily
comprised of (i) its Sterling system, which consists of 265 miles of gas
gathering pipelines and a gas processing plant in the Sterling area of the
Permian Basin, and (ii) over 1,900 miles of gas gathering pipelines in
Appalachia. The Sterling plant is a
 
                                       42
<PAGE>   45
 
refrigerated turbo-expander cryogenic gas plant that was placed in service in
early 1995. The plant, designed for approximately 25,000 Mcf/d, is currently
operating at 87% of capacity. The Company estimates that the plant's capacity
can be increased to 35,000 Mcf/d for approximately $4 million in additional
capital expenditures.
 
     The Appalachian gas gathering systems serve to transport a majority of the
Company's Appalachian gas production as well as third party gas to major
trunklines and directly to industrial end-users. This affords the Company
considerable control and flexibility in marketing its Appalachian production.
Third parties who transport their gas through the systems are charged a
gathering fee ranging from $0.20 to $0.32 per Mcf.
 
OIL AND GAS MARKETING
 
     In order to handle more efficiently the sale of its natural gas, the
Company began to market its own gas production in 1993. On a pro forma basis,
the Company is currently marketing 173 Mmcf/d for its own account as well as
additional volumes for third party producers. The Company's gas production is
sold primarily to utilities and directly to industrial users.
 
     The Company has managed the impact of potential price declines by
developing a balanced portfolio of fixed price and market sensitive contracts
and commodity hedging. On a pro forma basis, approximately 47% of average gas
production at December 31, 1996 was sold subject to fixed price sales contracts.
These fixed price contracts are at prices ranging from $2.15 to $3.70 per Mcf.
The fixed price contracts with terms of less than one year, between one and five
years and greater than five years constitute approximately 31%, 65% and 4%,
respectively, of the volume sold under fixed price contracts.
 
     From time to time, the Company enters into oil and natural gas price hedges
to reduce its exposure to commodity price fluctuations. At December 31, 1996,
approximately 12% on an Mcfe basis of the Company's monthly production for the
period January 1997 to April 1997 was hedged under such arrangements. No
production after this period was hedged. In the future, the Company may hedge a
larger percentage of its production.
 
     Approximately 30% of the Company's pro forma December 1996 gas production
on an Mcfe basis was attributable to Appalachia. Gas production in Appalachia
has historically received a higher price, due to its proximity to the
northeastern gas markets.
 
     The Company's oil production is sold at the well site at posted field
prices tied to the spot oil markets. Oil purchasers are selected on the basis of
price and service.
 
     As part of the Cometra Acquisition, the Company acquired a gas contract,
which expires June 30, 2000, with a major Texas gas utility company representing
18% of the Company's pro forma December 1996 production on an Mcfe basis. The
price paid pursuant to the contract was $3.70 per Mcf at December 31, 1996 (55%
higher than average 1996 natural gas prices received by the Company) and
escalates at $0.05 per Mcf per annum. No other purchaser of the Company's oil or
gas during 1996 exceeded 10% of the Company's total revenues.
 
FACILITIES
 
     The Company owns a 24,000 square foot facility located on approximately
seven acres near Hartville, Ohio. The facility houses certain operating and
administrative personnel. The Company leases approximately 33,000 square feet in
Fort Worth and Oklahoma City under standard office lease arrangements that
expire at various times through December 2003. All facilities are adequate to
meet the Company's existing needs and can be expanded with minimal expense.
 
     The Company owns various rolling stock and other equipment which is used in
its field operations. Such equipment is believed to be in good repair and, while
such equipment is important to its operations, it can be readily replaced as
necessary.

EMPLOYEES
 
     As of January 17, 1997, the Company had 268 full-time employees, 163 of
whom were field personnel. None are covered by a collective bargaining agreement
and management believes that its relationship with its employees is good.
 
LEGAL PROCEEDINGS
 
     The Company is involved in various legal actions and claims arising in the
ordinary course of business. In the opinion of management, such litigation and
claims will be resolved without a material adverse effect on the Company's
financial position.

                              CERTAIN TRANSACTIONS
 
     During 1995, the Company incurred fees of $145,000 with The Hawthorne
Company for advisory services paid in connection with the purchase of oil and
gas properties. Mr. Aikman, a Director of the Company, is an executive officer
and a principal owner of The Hawthorne Company. The amount incurred was on a
basis similar to that paid by the Company to third parties for similar services.
 
     In 1995, the Company acquired SOCO's interest in 468 wells located in
Appalachia for $4 million. The price was determined based on arm's-length
negotiations through a third-party broker retained by SOCO. After completion of
this transaction, the Company and SOCO no longer held interests in any of the
same properties. Mr. Edelman is Chairman of the Company and also an officer,
director and shareholder of SOCO. Therefore, Mr. Edelman has an indirect
interest in the foregoing relationships and transactions between the Company and
SOCO.
 
                 DESCRIPTION OF CAPITAL STOCK AND INDEBTEDNESS
 
     The authorized capital stock of the Company consists of (i) 4,000,000
shares of serial preferred stock, $1.00 par value, and (ii) 35,000,000 shares of
Common Stock $.01 par value. As of January 17, 1997, the Company had outstanding
14,801,654 shares of Common Stock and 1,150,000 shares of $2.03 Convertible
Preferred Stock.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to receive dividends if, when and as
declared by the Board of Directors of the Company out of funds legally available
therefor (however, the Indenture for the Notes and the Credit Facility contain
certain restrictions on the payment of cash dividends. If there is any arrearage
in the payment of dividends on any preferred stock, the Company may not pay
dividends upon, repurchase or redeem shares of its Common Stock. All shares of
Common Stock have equal voting rights on the basis of one vote per share on all
matters to be voted upon by stockholders. Cumulative voting for the election of
directors is not permitted. Shares of Common Stock have no preemptive,
conversion, sinking fund or redemption provisions and are not liable for further
call or assessment. Each share of Common Stock is entitled to share on a pro
rata basis in any assets available for distribution to the holders of the Common
Stock upon liquidation of the Company after satisfaction of any liquidation
preference on any series of the Company's preferred stock. All outstanding
shares of Common Stock have been, and all shares offered in the Common Stock
Offering will be when issued, validly issued, fully paid and nonassessable.
 
OPTIONS
 
     The Company's stock option plan, which is administered by the Compensation
Committee, provides for the granting of options to purchase shares of Common
Stock to key employees and certain other persons who are not employees for
advice or other assistance or services to the Company. The plan permits the
granting of options to acquire up to 2,000,000 shares of Common Stock subject to
a limitation of 10% of the outstanding Common Stock on a fully diluted basis. At
January 17, 1997, a total of 1,239,432 options had been granted under the plan
of which options to purchase 523,932 shares were exercisable at that date. The
options outstanding at January 17, 1997 were granted at an exercise price of
$3.38 to $10.50 per share. The exercise price of all such options was equal to
the fair market value of the Common Stock on the date of grant. All were options
granted for a term of five years, with 30% of the options becoming exercisable
after one year, an additional 30% becoming exercisable after two years and the
remaining options becoming exercisable after three years.
 
WARRANTS
 
     Warrants to acquire 20,000 shares of Common Stock at a price of $12.88 per
share were outstanding at September 30, 1996. These warrants expire in December
1997.
 
PREFERRED STOCK
 
     The Board of Directors of the Company, without action by stockholders, is
authorized to issue shares of serial preferred stock in one or more series and,
within certain limitations, to determine the voting rights
 
                                       49
<PAGE>   52
 
(including the right to vote as a series on particular matters), preferences as
to dividends and the liquidation, conversion, redemption and other rights of
each such series. The Board of Directors could issue a series with rights more
favorable with respect to dividends, liquidation and voting than those held by
the holders of its Common Stock. At January 17, 1997, 1,150,000 shares of
Preferred Stock were outstanding, designated as $2.03 Convertible Exchangeable
Preferred Stock, Series C (the "$2.03 Convertible Preferred Stock").
 
     The $2.03 Convertible Preferred Stock bears an annual dividend rate of
$2.03 payable quarterly. If dividends have not been paid on the $2.03
Convertible Preferred Stock, the Company cannot redeem or pay dividends on
shares of stock ranking junior to the $2.03 Convertible Preferred Stock. No new
serial preferred stock can be created with rights superior to those of the $2.03
Convertible Preferred Stock, as to dividends and liquidation rights, without the
approval of the holders of a majority of the $2.03 Convertible Preferred Stock.
In addition, the holders of the $2.03 Convertible Preferred Stock are entitled
to one vote for each share owned. Additionally, if dividends remain unpaid for
six full quarterly periods, or if any future class of preferred stockholders is
entitled to elect members of the Board of Directors based on actual missed and
unpaid dividends, the number of members of the Board of Directors will be
increased to such number as may be necessary to entitle the holders of the $2.03
Convertible Preferred Stock and such other future preferred stockholders, voting
as a single class, to elect one-third of the members of the Board of Directors.
The $2.03 Convertible Preferred Stock has liquidation rights of $25 per share.
The Company may exchange the $2.03 Convertible Preferred Stock for an aggregate
of $28,750,000 principal amount of 8.125% Convertible Subordinated Notes due
December 31, 2005. Each share of $2.03 Convertible Preferred Stock is
convertible into Common Stock at a conversion price of $9.50 per share, subject
to adjustment under certain circumstances. The conversion price will be reduced
for a limited period (but to not less than $5.21) if a change in control or
fundamental change in the Company occurs at a time that the market price of the
Common Stock is less than the conversion price. The Company may redeem the $2.03
Convertible Preferred Stock at any time after November 1, 1998, at redemption
prices declining from $26.50 to $25.00 per share, plus cumulative unpaid
dividends.
 
6% CONVERTIBLE SUBORDINATED DEBENTURES DUE 2007
 
     On December 27, 1996, the Company sold $55,000,000 aggregate principle
amount of 6% Convertible Subordinated Debentures due 2007 (the "Convertible
Debentures") in a private offering not registered under the Securities Act. The
Convertible Debentures are convertible at any time prior to maturity, unless
previously redeemed or repurchased, into shares of Common Stock, at a conversion
price of $19.25 per share, subject to adjustment under certain circumstances.
The Convertible Debentures are unsecured and subordinate to all senior and
senior subordinated indebtedness and do not restrict the incurrence of
additional indebtedness by the Company or any of its subsidiaries. The
Convertible Debentures will mature on February 1, 2007. The Company may redeem
the Convertible Debentures, in whole or in part, on or after February 1, 2000,
at certain redemption prices, plus accrued but unpaid interest at the date fixed
for redemption. Upon certain changes of control of the Company, the Company is
required to offer to repurchase each holder's Convertible Debentures at a
purchase price equal to 100% of the principal amount thereof, plus accrued and
unpaid interest to the date of repurchase.
 
     Pursuant to a Registration Rights Agreement between the Company and the
initial purchasers of the Convertible Debentures, the Company has agreed to file
a shelf registration statement (the "Shelf Registration Statement") relating to
the Debentures and the shares of Common Stock issuable upon conversion of the
Convertible Debentures. The Company will use its reasonable best efforts to
maintain the effectiveness of the Shelf Registration Statement until the third
anniversary of the issuance of the Convertible Debentures, except that it shall
be permitted to suspend the use of the Shelf Registration Statement during
certain periods under certain circumstances. If the Company fails to meet
certain of its obligations under the Shelf Registration Statement, then a
supplemental payment will be made to the holders of the Convertible Debentures
or shares of Common Stock actually issued upon conversion of the Convertible
Debentures. During the first 90 days of such a default, the supplemental payment
will be $0.05 per week per $1,000 principal amount of the Convertible Debentures
and $0.0005 per week per share of such Common Stock. The amount of such
supplemental payment will increase over time if the default continues, subject
to a maximum
 
                                       50
<PAGE>   53
 
supplemental payment of $0.20 per week per $1,000 principal amount of
Convertible Debentures and $0.002 per week per share of Common Stock.
 
CREDIT FACILITY
 
     In connection with the financing of the Cometra Acquisition, the Company
and its subsidiaries will expand the existing credit facility with the bank
lenders. The Credit Facility will enable the Company to obtain revolving credit
loans and to issue letters of credit for the account of the Company from time to
time in an aggregate amount not to exceed $400 million (of which not more than
$125 million may be represented by letters of credit). The Borrowing Base, which
will initially be $400 million under the expanded facility, will be reduced to
$325 million 180 days after the closing of the Cometra Acquisition, unless
otherwise agreed by the lenders. The Borrowing Base is subject to semi-annual
determination and is calculated based upon a variety of factors, including the
discounted present value of estimated future net cash flow from oil and gas
production.
 
     The Company will be required to make a mandatory prepayment of all amounts
outstanding under the Credit Facility in excess of $325 million 180 days after
the closing of the Cometra Acquisition. At the Company's option, loans may be
prepaid, and revolving credit commitments may be reduced, in whole or in part at
any time in certain minimum amounts.
 
     At the Company's option, the applicable interest rate per annum will be
either LIBOR plus a margin ranging from 0.625% to 1.125% or the Alternate Base
Rate (as defined) plus a margin ranging from 0% to 0.25%. The Alternate Base
Rate is the highest of (a) the agent banks' reference rate, (b) the secondary
market rate for certificates of deposit (adjusted for maximum statutory reserve
requirements) plus 1.0% and (c) the federal funds effective rate plus 0.5%.
Until the occurrence of the Trigger Event, the interest rate margins will be
increased by 50 basis points prior to March 31, 1997 and 100 basis points
thereafter.
 
     The obligations of the Company under the Credit Facility will be
unconditionally and irrevocably guaranteed by each of the Company's direct and
indirect domestic subsidiaries (collectively, the "Subsidiary Guarantors"). In
addition, the Credit Facility will be secured by first priority security
interests in (i) existing mortgaged oil and gas properties of the Company and
the Cometra Properties, (ii) all accounts receivable, inventory and intangibles
of the Company and the Subsidiary Guarantors, and (iii) all of the capital stock
of the Company's direct or indirect subsidiaries. Substantially all of the
assets of the Company will be pledged as collateral if, 90 days after the
closing of the Cometra Acquisition, the Borrowing Base and amounts outstanding
under the Credit Facility have not been reduced to $325 million. Such additional
security interests will be released upon the (i) reduction of the amounts
outstanding under the Credit Facility to $325 million (or the then determined
Borrowing Base) and (ii) issuance of $75 million of Common Stock and/or the sale
of Company assets in excess of the Borrowing Base value attributable to such
assets as agreed by the lenders.
 
     Immediately following the Cometra Acquisition, the Company expects that
approximately $385 million will be outstanding (including $125 million of then
outstanding letters of credit to secure the promissory note issued to Cometra as
part of the purchase price in the Cometra Acquisition) under the Credit
Facility. Upon consummation of the Offerings, approximately $230.9 million will
be outstanding under the Credit Facility. Accordingly, the Company believes that
a Trigger Event will occur upon completion of the Offerings.
 
     The Credit Facility contains various covenants that, among other things,
will restrict the ability of the Company to dispose of assets, incur additional
indebtedness, repay other indebtedness or amend other debt instruments, pay
dividends, create liens on assets, make investments or acquisitions, engage in
mergers or consolidations, make capital expenditures or engage in certain
transactions with affiliates. In addition, under the Credit Facility, the
Company will be required to comply with specified minimum interest coverage and
maximum leverage ratios.

and which are expected to be productive due to both the well log characteristics
and analogous production in the immediate vicinity of the wells.
 
Proved developed producing reserves.  Proved reserves that can be expected to be

The Board of Directors and Stockholders
     Lomak Petroleum, Inc.
 
     We have audited the accompanying consolidated balance sheets of Lomak
Petroleum, Inc. (a Delaware corporation) as of December 31, 1994 and 1995, and
the related consolidated statements of income, stockholders' equity and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Lomak Petroleum, Inc. as of
December 31, 1994 and 1995, and the results of its operations and its cash flows
for the years then ended, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1)  ORGANIZATION AND NATURE OF BUSINESS
 
     Lomak Petroleum, Inc. ("Lomak" or the "Company") is an independent oil and
gas company engaged in the acquisition, development, exploration and enhancement
of oil and gas properties in the United States. Lomak's core areas of operation
are located in Texas, Oklahoma and Appalachia. The company has grown through a
combination of acquisition, development, exploration and enhancement activities.
Since January 1, 1990, 60 acquisitions have been consummated at a total cost of
approximately $200 million and approximately $24 million has been expended on
development and exploration activities. As a result, proved reserves and
production have each grown during this period at a rate in excess of 80% per
annum. At December 31, 1995, proved reserves totaled 298 Bcfe, having a pre-tax
present value at constant prices on that date of $229 million and a reserve life
of nearly 12 years.
 
     Lomak's acquisition effort is focused on properties with prices of less
than $30 million within its core areas of operation. Management believes these
purchases are less competitive than those involving larger property interests.
To the extent purchases continue to be made primarily within existing core
areas, efficiencies in operations, drilling, gas marketing and administration
should be realized. In 1994, Lomak initiated a program to exploit its inventory
of over 500 development projects. In the future, Lomak expects its growth to be
driven principally by a combination of acquisitions and development and, to a
lesser extent, exploration.
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The accompanying financial statements include the accounts of the Company,
all majority owned subsidiaries and its pro rata share of the assets,
liabilities, income and expenses of certain oil and gas properties. Temporary
investments with an initial maturity of ninety days or less are considered cash
equivalents.
 
  Oil and Gas Properties
 
     The Company follows the successful efforts method of accounting for oil and
gas properties. Exploratory costs which result in the discovery of reserves and
the cost of development wells are capitalized. Geological and geophysical costs,
delay rentals and costs to drill unsuccessful exploratory wells are expensed.
Depletion is provided on the unit-of-production method. Oil is converted to Mcfe
at the rate of six Mcf per barrel. The depletion rates per Mcfe were $.74, $.74
and $.73 in 1993, 1994 and 1995, respectively. Approximately $5.3 million, $12.9
million and $12.2 million of oil and gas properties were classified as proved
undeveloped or unproved and, therefore, not subject to depletion as of December
31, 1993, 1994 and 1995, respectively. These costs are assessed periodically to
determine whether their value has been impaired, and if impairment is indicated,
the excess costs are charged to expense.
 
  Gas Transportation and Field Services Assets
 
     The Company owns and operates approximately 1,900 miles of gas gathering
lines in proximity to its principal gas properties. Depreciation is calculated
on the straight-line method based on estimated useful lives ranging from four to
fifteen years.
 
     The Company receives fees for providing field related services. These fees
are recognized as earned. Depreciation is calculated on the straight-line method
based on estimated useful lives ranging from one to six years, except for
buildings which are being depreciated over ten to twenty-five year periods.

                             LOMAK PETROLEUM, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In September 1994, the Company sold substantially all of its brine disposal
and well servicing assets located in the Appalachian region for approximately
$1.8 million. Through an acquisition completed in early 1995, the Company began
conducting brine disposal and well services in Oklahoma.
 
  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 revenues and expenses during the
reporting period. Accrual results could differ from those estimates.
 
  Nature of Business
 
     The Company operates in an environment with many financial risks,
including, but not limited to, the ability to acquire additional economically
recoverable oil and gas reserves, the inherent risks of the search for,
development of and production of oil and gas, the ability to sell oil and gas at
prices which will provide attractive rates of return, and the highly competitive
nature of the industry and worldwide economic conditions. The Company's ability
to expand its reserve base and diversify its operations is also dependent upon
the Company's ability to obtain the necessary capital through operating cash
flow, additional borrowings or additional equity funds.
 
  Financial Instruments
 
     The Company's financial instruments include cash and equivalents, accounts
receivable, accounts payable and debt obligations. The book value of cash and
equivalents, accounts receivable and payable and short term debt are considered
to be representative of fair value because of the short maturity of these
instruments. The Company believes that the carrying value of its borrowings
under its bank credit facility approximates their fair value as they bear
interest at the bank's prime rate or Libor. The Company's accounts receivable
are concentrated in the oil and gas industry. The Company does not view such a
concentration as an unusual credit risk.
 
     Interest rate swap agreements, which are used by the Company in the
management of interest exposure, is accounted for on an accrual basis. Income
and expense resulting from these agreements are recorded in the same category as
expense arising from the related liability. Amounts to be paid or received under
interest rate swap agreements are recognized as an adjustment to expense in the
periods in which they accrue. At December 31, 1995, the Company had $40 million
of borrowings subject to two swap agreements at rates of 6.25% and 6.49% through
no less than July 1997 and no longer than October 1999, respectively.
 
     The Company uses futures, option and swap contracts to reduce the effects
of fluctuations in crude oil and natural gas prices. At December 31, 1995, the
Company had open contracts for natural gas price swaps in the amount of 360,000
MMbtu's. These contracts expire monthly through September 1996. The resulting
transaction gains and losses are included in net income and are determined
monthly. Net gains for the year ended December 31, 1995 approximated $221,000
relating to these derivatives.
 
  Accounting Standards
 
     In March 1995, the Financial Standards Board (FASB) issued SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of." This standard requires the review of long-lived assets for
impairment. Although the Company in the past has routinely reviewed its oil and
gas assets for impairment, the new accounting rules may require a different
grouping which may affect the amount of impairment, if any. SFAS No. 121 is
required to be adopted for financial statements with fiscal

years beginning after December 15, 1995 and allows the cumulative effect of the
accounting change to be reported in net income in the year of adoption. The
Company is currently reviewing the accounting standard and has not yet
determined the effect, if any, on its consolidated financial position or results
of operations.
 
     In October 1995, FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation." This standard requires an audited pro forma footnote disclosure
of what net income and earnings per share would have been for the Company based
upon valuing employee options and other stock based compensation, at their
estimated fair value using an option pricing model. SFAS No. 123 is required to
be adopted for financial statements with fiscal years beginning after December
15, 1995. The Company is currently reviewing the accounting standard and has not
yet determined the effect, if any, on its financial statements.
 
  Earnings per Common Share
 
     Net income per share is computed by subtracting preferred dividends from
net income and dividing by the weighted average number of common and common
equivalent shares outstanding. The calculation of fully diluted earnings per
share assumes conversion of convertible securities when the result would be
dilutive. Outstanding options and warrants are included in the computation of
net income per common share when their effect is dilutive.
 
  Reclassifications
 
     Certain reclassifications have been made to prior period presentation to
conform with current period classifications.
 
(3)  ACQUISITION AND DEVELOPMENT
 
     Since 1990, the Company has acquired $200 million of oil and gas properties
and field service assets. During 1995, the Company completed $71.1 million of
acquisitions. The purchases were funded by working capital, advances under a
revolving credit facility and the issuance of Common Stock. These acquisitions
are discussed below.

at December 31, 1994. Acquisition costs of approximately $46.5 million have been
capitalized in regards to this acquisition. Red Eagle's assets included
interests in approximately 370 producing wells located primarily in the Okeene

     The Company maintains a $250 million revolving bank credit facility. The
facility provides for a borrowing base which is subject to semi-annual
redeterminations. At December 31, 1995, the borrowing base on the credit
facility was $105 million. The facility bears interest at prime rate or LIBOR
plus 0.75% to 1.25% depending upon the percentage of the borrowing base drawn.
Interest is payable quarterly and the loan is payable in sixteen quarterly
installments beginning February 1, 1999. A commitment fee of  3/8% of the
undrawn balance is payable quarterly. It is the Company's policy to extend the
term period of the credit facility annually. The weighted average interest rates
on these borrowings were 6.3% and 7.3% for the years ended December 31, 1994 and
1995, respectively. The weighted average interest rate gives effect to interest
rate swap arrangements which have the effect of fixing the interest rate on $40
million of the credit facility at a rate of 6.4%. The existing interest rate
swap arrangements will remain in effect through no less than July 1997 and no
longer than October 1999. The Company's other debt is comprised of secured
equipment financings.
 
     The debt agreements contain various covenants relating to net worth,
working capital maintenance and financial ratio requirements. Interest paid
during the years ended December 31, 1993, 1994 and 1995 totaled $1.2 million,
$2.8 million and $4.9 million, respectively.
 
     Maturities of indebtedness as of December 31, 1995 were as follows (in

     In January 1995, a lawsuit (the "Lawsuit") was filed in the Delaware Court
of Chancery, New Castle County, against Red Eagle Resources Corporation, each of
the members of the Board of Directors of Red Eagle and the Company. The
Plaintiff sought to represent all holders (the "Class") of Red Eagle Common
Stock, excluding the Red Eagle Directors and Lomak. A settlement was reached
during 1995 under which the Company paid $250,000 in cash plus 74,286 shares of
the Company's Common Stock.
 
     The Company is involved in various other legal actions and claims arising
in the ordinary course of business. In the opinion of management, such

(7)  EQUITY SECURITIES
 
     In 1993, $5,000,000 of 7 1/2% cumulative convertible exchangeable preferred
stock (the "7 1/2% Preferred Stock") was privately placed. The 7 1/2% Preferred
Stock is convertible, at the option of the holders, into 576,945 shares of
Common Stock, at an average conversion price of $8.67 per share. The Company may
convert the 7 1/2% Preferred Stock into Common Stock if the closing price for
the Common Stock exceeds an average price of $11.70 for twenty out of thirty
consecutive trading days. Beginning in July 1996, the Company may redeem the
7 1/2% Preferred Stock at a 7 1/2% premium to liquidation value. Holders of the
7 1/2% Preferred Stock are entitled to two votes per share on matters presented
to the shareholders. At the Company's option, it can exchange the 7 1/2%
Preferred Stock for convertible subordinate notes due July 1, 2003. The notes
carry the same conversion and redemption terms as the 7 1/2% Preferred Stock.
 
     In November 1995, the Company sold 1,150,000 shares of $2.03 convertible
exchangeable preferred stock (the "$2.03 Preferred Stock") for $28.8 million.
The $2.03 Preferred Stock is convertible into the Company's Common Stock at a
conversion price of $9.50 per share, subject to adjustment in certain events.
The $2.03 Preferred Stock is redeemable, at the option of the Company, at any
time on or after November 1, 1998, at redemption prices beginning at 105%. At
the option of the Company, the $2.03 Preferred Stock is exchangeable for the
Company's 8 1/8% convertible subordinated notes due 2005. The notes would be
subject to the same redemption and conversion terms as the $2.03 Preferred
Stock.
 
     In December 1995, the Company privately placed 1.2 million shares of its
Common Stock for $10.2 million to a state sponsored retirement plan. Warrants to
acquired 40,000 shares of Common Stock were outstanding at December 31, 1995.
The warrants have an exercise price of $7.50 per share and expire in December
1996.
 
(8)  STOCK OPTION AND PURCHASE PLAN
 
     The Company maintains a Stock Option Plan which authorizes the grant of
options of up to 1.5 million shares of Common Stock. However, no new options may
be granted which would result in their being outstanding aggregate options
exceeding 10% of the Company's common shares outstanding plus those shares
issuable under convertible securities. Under the plan, incentive and
non-qualified options may be issued to officers, key employees and consultants.
The plan is administered by the Compensation Committee of the Board. All options
issued under the plan vest 30% after one year, 60% after two years and 100%
after three years. The following is a summary of stock option activity:

     In 1993, the Company adopted FASB Statement No. 109, "Accounting for Income
Taxes". Under Statement 109, the liability method is used in accounting for
income taxes. Under this method, deferred tax assets and liabilities are
determined based on differences between financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse. Prior to
the adoption, income tax expense was determined using the deferred method and
the Company reported tax expense equal to current alternative minimum taxes
payable. Deferred taxes have not been provided on temporary differences prior to
adoption due to the existence of net operating loss and other carryforwards.

     As permitted by Statement 109, the Company has elected not to restate prior
year financial statements. As a result of tax basis in excess of the basis on
the financial statements at January 1, 1993, the Company estimated deferred tax
assets of $2.6 million and deferred tax liabilities of $0.9 million, for net
deferred tax assets of $1.7 million. Due to uncertainty as to the realizability
of the tax benefit, a valuation allowance was established for the full amount of
the net deferred tax assets. In 1993, 1994 and 1995, income taxes were reduced
from the statutory rate of 34% by approximately $0.5 million, $0.9 million and
$0.3 million, respectively, through realization of a portion of the valuation
allowance, resulting in $1.2 million, $0.3 million and $40,000, respectively of
the remaining allowance at December 31, 1993, 1994 and 1995.
 
     During 1993, the Company acquired Mark Resources Corporation (See Note 3),
a taxable business combination accounted for as a purchase. Deferred tax assets
of $3.9 million and a deferred tax liability of $8.1 million were recorded in
connection with the business combination. During 1994, the Company acquired
Gillring Oil Company and Grand Banks Energy Company, taxable business
combinations accounted for as purchases. Deferred tax assets of $3.5 million and
deferred tax liabilities of $3.4 million were recorded in connection with these
transactions. The Company acquired Red Eagle Resources Corporation, a taxable
business combination accounted for as a purchase. Deferred tax liabilities of
$12.3 million and deferred tax assets of $0.3 million were recorded in
connection with this transaction.
 
     As a result of the Company's issuance of equity and convertible debt
securities, it experienced a change in control during 1988 as defined by Section
382 of the Internal Revenue Code. The change in control placed limitations to
the utilization of net operating loss carryovers. At December 31, 1995, the
Company had available for federal income tax reporting purposes net operating
loss carryovers of approximately $13.3 million which are subject to annual
limitations as to their utilization and otherwise expire between 1996 and 2010,
if unused. The Company has alternative minimum tax net operating loss carryovers
of $8.2 million which are subject to annual limitations as to their utilization
and otherwise expire from 1996 to 2009 if unused. The Company has statutory
depletion carryover of approximately $8.5 million and an alternative minimum tax
credit carryover of approximately $500,000. The statutory depletion carryover
and alternative minimum tax credit carryover are not subject to limitation or
expiration.
 
(11)  MAJOR CUSTOMERS
 
     The Company markets its oil and gas production on a competitive basis. The
type of contract under which gas production is sold varies but can generally be
grouped into three categories: (a) life-of-the-well; (b) long-term (1 year or
longer); and (c) short-term contracts which may have a primary term of one year,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
but which are cancelable at either party's discretion in 30-120 days. At
December 31, 1995, approximately 59% of the Company's gas production was being
sold under market sensitive contracts which do not contain floor price
provisions. For the year ended December 31, 1995, no one customer accounted for
more than 10% of the Company's total oil and gas revenues. Oil is sold on a
basis such that the purchaser can be changed on 30 days notice. The price
received is generally equal to a posted price set by the major purchasers in the
area. The company sells to oil purchasers on a basis of price and service.
 
     The Company has currently hedged less than 3% of its monthly production
through September 1996. These hedges involve fixed price arrangements and other
price arrangements at a variety of prices, floors and caps. Although these
hedging activities provide the Company some protection against falling prices,
these activities also reduce the potential benefits to the Company of price
increases above the levels of the hedges.

(13)  SUBSEQUENT EVENTS
 
     In February 1996, the Company completed three oil and gas property
acquisitions for $17.5 million of consideration. The properties are located in
Lomak's core operating areas of Appalachia and Texas. In aggregate, the
acquisitions are estimated to contain proved reserves of 20.2 Bcf of gas and
240,000 of Bbls of oil, or 21.6 Bcfe in total.
 
     In March 1996, the Company's Board of Directors approved resolutions
authorizing the Company to repurchase shares of its Common Stock from odd-lot
holders. The Company will acquire any and all shares from stockholders owning 99
or fewer shares for cash at market prices. Additionally, the Board of Directors
approved a dividend of $.01 per share to holders of its Common Stock to be paid
on March 29, 1996.
 
(14)  RELATED PARTY TRANSACTIONS
 
     Mr. Edelman, Chairman of the Company, is also an executive officer and
shareholder of Snyder Oil Corporation ("SOCO"). At December 31, 1995, Mr.
Edelman owned 6.0% of the Company's Common Stock. In 1994, the Company
repurchased 30,000 shares of its Common Stock from SOCO for $240,000. The
purchase price was based upon the prior day's closing price for the stock. In
1995, SOCO sold its remaining shares of the Company's Common Stock.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In 1995, the Company acquired SOCO's interest in certain wells located in
Appalachia for $4 million. The price was determined based on arms-length
negotiations through a third-party broker retained by SOCO. Subsequent to the
transaction, the Company and SOCO no longer held interests in any of the same
properties.
 
     During 1994 and 1995, the Company incurred fees of $369,000 and $145,000,
respectively, to the Hawthorne Company in connection with acquisitions. Mr.
Aikman, a director of the Company, is an executive officer and a principal owner
of the Hawthorne Company. The fees were consistent with those paid by the
Company to third parties for similar services.
 
(15)  UNAUDITED SUPPLEMENTAL RESERVE INFORMATION
 
     The Company's proved oil and gas reserves are located in the United States.
Proved reserves are those quantities of crude oil and natural gas which, upon
analysis of geological and engineering data, can with reasonable certainty be
recovered in the future from known oil and gas reservoirs. Proved developed
reserves are those proved reserves which can be expected to be recovered from
existing wells with existing equipment and operating methods. Proved undeveloped
oil and gas reserves are proved reserves that are expected to be recovered from
new wells on undrilled acreage.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The "Standardized Measure of Discounted Future Net Cash Flows Relating to
Proved Oil and Gas Reserves" (Standardized Measure) is a disclosure requirement
under Statement of Financial Accounting Standards No. 69 "Disclosures about Oil
and Gas Producing Activities". The Standardized Measure does not purport to
present the fair market value of proved oil and gas reserves. This would require
consideration of expected future economic and operating conditions, which are
not taken into account in calculating the Standardized Measure.
 
     Future cash inflows were estimated by applying year end prices to the
estimated future production less estimated future production costs based on year
end costs. Future net cash inflows were discounted using a 10% annual discount
rate to arrive at the Standardized Measure.

(1)  ORGANIZATION
 
     Lomak Petroleum, Inc. ("Lomak" or the "Company") is an independent oil and
gas company engaged in the acquisition, production, development and exploration
of oil and gas in the United States. Lomak's core areas of operation are located
in the Mid-Continent and Appalachia regions. Since January 1, 1990, the Company
has made 68 acquisitions at a total cost of $256 million and $34 million has
been expended on development and exploration activities. As a result, proved
reserves and production have each grown during this period at a rate in excess
of 80% per annum. At December 31, 1995, proved reserves totaled 298 Bcfe, having
a pre-tax present value at constant prices of $229 million and a reserve life of
nearly 12 years.
 
     Lomak's acquisition effort is focused on properties with prices of less
than $30 million within its core areas of operation. Management believes these
purchases are less competitive than those involving larger property interests.
To the extent purchases continue to be made primarily within existing core
areas, efficiencies in operations, drilling, marketing and administration should
be realized. In 1992, Lomak began to exploit its growing inventory of
development projects. In 1994, the Company initiated exploration activities. In
the future, Lomak expects its growth to be driven by a combination of
acquisitions, development and exploration.
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The accompanying financial statements include the accounts of the Company,
all majority owned subsidiaries and its pro rata share of the assets,
liabilities, income and expenses of certain oil and gas properties. Temporary
investments with an initial maturity of ninety days or less are considered cash
equivalents.
 
  Oil and Gas Properties
 
     The Company follows the successful efforts method of accounting.
Exploratory costs which result in the discovery of reserves and the cost of
development wells are capitalized. Geological and geographical costs, delay
rentals and costs to drill unsuccessful exploratory wells are expensed.
Depletion is provided on the unit-of-production method. Oil is converted to Mcfe
at the rate of six Mcf per barrel. The depletion rate per Mcfe produced was $.73
in both the third quarters of 1995 and 1996. Approximately $12.2 million ($11.5
million -- proved undeveloped properties and $.8 million -- unproved acreage)
and $21.7 million ($20.6 million proved undeveloped properties and $1.1
million -- unproved acreage) of oil and gas properties were not subject to
depletion as of December 31, 1995 and September 30, 1996, respectively. These
costs are assessed periodically to determine whether their value has been
impaired. If they have, the amount of any impairment is expensed.
 
  Gas Transportation and Field Service Assets
 
     The Company owns and operates over 1,900 miles of gas gathering systems in
proximity to its principal gas properties. Depreciation of these systems is
calculated on the straight-line method based on estimated useful lives ranging
from four to fifteen years.
 
     The Company receives fees for providing field related services. These fees
are recognized as earned. Depreciation is calculated on the straight-line method
based on estimated useful lives ranging from one to five years, except buildings
which are being depreciated over ten to twenty-five years.
 
     Nature of Business
 
     The Company operates in an environment with many financial risks,
including, but not limited to, the ability to acquire additional economically
recoverable oil and gas reserves, the inherent risks of the search for,

development of and production of oil and gas, the ability to sell oil and gas at
prices which will provide attractive rates of return, and the highly competitive
nature of the industry and worldwide economic conditions. The Company's ability
to expand its reserve base and diversify its operations is also dependent upon
the Company's ability to obtain the necessary capital through cash flow,
borrowings or equity funds.
 
     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 revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Financial Instruments and Hedging Activities

the Company's financial instruments:

</TABLE>
 
     The Company's financial instruments include cash and equivalents, accounts
receivable, accounts payable and debt obligations. The book value of cash and
equivalents, accounts receivable and payable and short term debt are considered
to be representative of fair value because of the short maturity of these
instruments. The Company believes that the carrying value of its borrowings
under its bank credit facility approximates their fair value as they bear
interest at rates indexed at LIBOR. The Company's accounts receivable are
concentrated in the oil and gas industry. The Company does not view such a
concentration as an unusual credit risk.
 
     A portion of the Company's prices received in crude oil and natural gas
sales are periodically hedged against market risks through the use of futures,
option or swap contracts. The gains and losses on these instruments are included
in the valuation of the production being hedged in the contract month and are
included as an adjustment to oil and gas revenue. The company also manages
interest rate risk on its credit facility through the use of interest rate swap
agreements. Gains and losses on swap agreements are included as an adjustment to
interest expenses.
 
  Marketable Securities
 
     In 1996, the Company adopted Statement of Financial Accounting Standards
No. 115, "Accounting for Certain Investments in Debt and Equity Securities."
Under Statement No. 115, debt and marketable equity securities are required to
be classified in one of three categories: trading, available-for-sale, or held
to maturity. The Company's equity securities qualify under the provisions of
Statement No. 115 as available-for-sale. Such securities are recorded at fair
value, and unrealized holding gains and losses, net of the related tax effect,
are not reflected in earnings or as a separate component of stockholders' equity
because the amounts are immaterial. A decline in the market value of an
available-for-sale security below cost that is deemed other than temporary is
charged to earnings and results in the establishment of a new cost basis for the
security. Realized gains and losses are determined on the specific
identification method and are reflected in income.

  Net Income Per Share
 
     Net income per share is computed by subtracting preferred dividends from
net income and dividing by the weighted average number of common and common
equivalent shares outstanding. The calculation of fully diluted earnings per
share assumes conversion of convertible securities when the result would be
dilutive. Outstanding options and warrants are included in the computation of
net income per common share when their effect is dilutive.
 
  Reclassifications
 
     Certain reclassifications have been made to prior period presentations to
conform with current period classifications.
 
(3)  ACQUISITIONS
 
     Since 1990, the Company has acquired over $256 million of oil and gas
properties. During 1995, the Company completed $71.1 million of acquisitions. In
the first nine months of 1996, acquisitions totaling $56.8 million were
completed. The purchases were funded by working capital, advances under a
revolving credit facility and the issuance of common and preferred stock. These
acquisitions are discussed below.
 
  1996 Acquisitions
 
     Mid-Continent
 
     Bannon Interests.  In April 1996, the Company acquired interests in
approximately 270 producing wells and 108 proven recompletion and development
drilling opportunities for $37.0 million. Also included were 17,300 net
undeveloped acres located in east and south Texas.
 
     The Company purchased incremental interests in approximately 40 properties
located in the Laura La Velle Field of east Texas for $.8 million.
 
     Appalachia
 
     Eastern Petroleum Company.  In January 1996, the Company acquired proven
oil and gas reserves and 40 miles of gas gathering lines in Ohio for $13.7
million. In the second quarter of 1996, the Company initiated a program
extending purchase offers to other interest owners in these properties. Through
September 30, 1996, interests in 61 wells had been purchased for approximately
$100,000.
 
     The Company purchased incremental interests in approximately 440 operated
properties in Pennsylvania and Ohio for $5.2 million.
 
  1995 Acquisitions
 
     Mid-Continent
 
     Red Eagle Resources Corporation.  In late 1994, the Company acquired
effective control of Red Eagle through the purchase of two stockholders'
holdings. In early 1995, the remaining stockholders of Red Eagle voted to
approve the merger of Red Eagle with a wholly owned subsidiary of the Company in
exchange for approximately 2.2 million shares of the Company's Common Stock. The
additional equity of Red Eagle acquired in February 1995 was reflected as
minority interest on the Company's balance sheet at December 31, 1994.
Acquisition costs of approximately $46.5 million were capitalized in regards to
this acquisition. Red Eagle's assets included interests in approximately 370
producing wells located primarily in the Okeene Field of Oklahoma's Anadarko
Basin. Subsequently, the Company acquired additional interests in 70 Red Eagle
wells for $1.7 million.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     the Company maintains a $250 million revolving bank credit facility. The
facility provides for a borrowing base which is subject to semi-annual
redeterminations. At November 4, 1996, the borrowing base on the credit facility
was $150 million, of which $112 million was outstanding. The facility bears
interest at the prime rate or LIBOR plus 0.75% to 1.25% depending upon the
percentage of the borrowing base drawn. Interest is payable quarterly and the
loan is payable in sixteen quarterly installments beginning February 1, 1999. A
commitment fee of  3/8% of the undrawn balance is payable quarterly. It is the
Company's policy to extend the term period of the credit facility annually. The
weighted average interest rate on these borrowings were 7.5% and 6.7% for the
nine months ended September 30, 1995 and 1996, respectively. The weighted
average interest rate gives effect to two $20 million interest rate swap
arrangements which have the effect of fixing the interest rate on $40 million of
the credit facility at a rate of 6.4%. The interest rate swaps will remain in
effect through July 1997 and October 1997, respectively, but may be extended at
the counterparties' option for two years.
 
     The debt agreements contain various covenants relating to net worth,
working capital maintenance and financial ratio requirements. Interest paid in
cash during the nine months ended September 30, 1995 and 1996 totaled $3.5
million and $4.1 million, respectively.
 
(5)  FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
 
     The Company uses derivative financial instruments to manage well-defined
commodity price and interest rate risks and does not use them for speculative
purposes.
 
     Periodically, the Company enters into futures, option and swap contracts to
reduce the effects of fluctuations in crude oil and natural gas prices. At
September 30, 1996, the Company had open contracts for oil and gas price swaps
of 280,000 barrels and 586,000 Mcfs. These swap contracts are designed to set
average prices of $23.09 per barrel and $1.98 per Mcf. While these transactions
have no carrying value, their fair value, represented by the estimated amount
that would be required to terminate the contracts, was a net cost of
approximately $129,000 at September 30, 1996. These contracts expire monthly
through March 1997. In October 1996, the Company entered into swap contracts for
an additional 250,000 barrels of oil at an average price per barrel of $22.86.
These contracts expire monthly through April 1997. The gains or losses on the
Company's hedging transactions is determined as the difference between the
contract price and a reference price, generally closing prices on the New York
Mercantile Exchange. The resulting transaction gains and losses are determined
monthly and are included in net income for the contract month as an adjustment
to oil and gas revenue. Net gains relating to these derivatives for the nine
months ended September 30, 1996 approximated $29,700.
 
     Interest rate swap agreements, which are used by the Company in the
management of interest exposure, is accounted for on an accrual basis. Income
and expense resulting from these agreements are recorded in the same category as
expense arising from the related liability. Amounts to be paid or received under
interest rate swap agreements are recognized as an adjustment to expense in the
periods in which they accrue. At September 30, 1996, the Company had $40 million
of borrowings subject to two interest rate swap agreements at rates of 5.25% and
5.49% through July 1997 and October 1997, respectively, but may be extended at
the counterparties' option for two years. The agreements require that the
Company pay the counterparty interest at the above fixed swap rates and requires
the counterparty to pay the Company interest at the 30-day LIBOR rate. The
closing 30-day LIBOR rate on September 30, 1996 was 5.44%. The fair value of the
interest rate swap agreements at September 30, 1996, based upon current quotes
for equivalent agreements, amounted to $87,700, which represents the Company's
income if the agreements were terminated on this date. In October 1996, the
Company entered into a swap arrangement on an additional $20 million of the
credit facility at a rate of 5.7%, which will remain in effect through October
1998, but may be extended at the counterparties' option for two years.
 
     These financial instruments are executed with major financial or

counterparties or groups of counterparties. The credit worthiness of
counterparties is subject to continuing review and full performance is
anticipated.
 
(6)  COMMITMENTS AND CONTINGENCIES
 
     The Company is involved in various legal actions and claims arising in the
ordinary course of business. In the opinion of management, such litigation and
claims are likely to be resolved without material adverse effect on the
Company's financial position.
 
(7)  EQUITY SECURITIES
 
     In 1993, $5 million of 7 1/2% cumulative convertible exchangeable preferred
stock (the "7 1/2% Preferred Stock") was privately placed. In April and May
1996, the Company exercised it's option and converted the 7 1/2% Preferred Stock
into 576,945 shares of Common Stock.
 
     In November 1995, the Company sold 1,150,000 shares of $2.03 convertible
exchangeable preferred stock (the "$2.03 Preferred Stock") for $28.8 million.
The $2.03 Preferred Stock is convertible into the Company's Common Stock at a
conversion price of $9.50 per share, subject to adjustment in certain events.
The $2.03 Preferred Stock is redeemable, at the option of the Company, at any
time on or after November 1, 1998, at redemption prices beginning at 105%. At
the option of the Company, the $2.03 Preferred Stock is exchangeable for the
Company's 8 1/8% convertible subordinated notes due 2005. The notes would be
subject to the same redemption and conversion terms as the $2.03 Preferred
Stock.
 
     In December 1995, the Company privately placed 1.2 million shares of its
Common Stock for $10.2 million to a state employees retirement plan. In April
1996, the Company privately placed 600,000 shares of its Common Stock to a
limited number of institutional investors for approximately $6.9 million.
Warrants to acquire 40,000 shares of Common Stock at a price of $7.50 per share
were exercised in October 1996. Additionally, warrants to acquire 20,000 shares
of Common Stock at a price of $12.88 per share were outstanding at September 30,
1996 and will expire in December 1997.
 
(8)  STOCK OPTION AND PURCHASE PLAN
 
     The Company maintains a Stock Option Plan which authorizes the grant of
options of up to 2.0 million shares of Common Stock. However, no new options may
be granted which would result in their being outstanding aggregate options
exceeding 10% of common shares outstanding plus those shares issuable under
convertible securities. Under the plan, incentive and non-qualified options may
be issued to officers, key employees and consultants. The plan is administered
by the Compensation Committee of the Board. All options issued under the plan
vest 30% after one year, 60% after two years and 100% after three years. During
the nine months ended September 30, 1996, options covering 109,750 shares were
exercised at prices ranging from $3.38 to $8.25 per share. At September 30,
1996, options covering a total of 1.2 million shares were outstanding under the
plan, of which 504,000 options were exercisable. The exercise prices of the
outstanding options range from $3.38 to $10.50.
 
     In 1994, the stockholders approved the 1994 Outside Directors Stock Option
Plan (the "Directors Plan"). Only Directors who are not employees of the Company
are eligible under the Directors Plan. The Directors Plan covers a maximum of
200,000 shares. At September 30, 1996, 76,000 options were outstanding under the
Directors Plan of which 16,800 were exercisable as of that date. The exercise
price of the options ranges from $7.75 to $13.88 per share.
 
     In 1994, the stockholders approved the 1994 Stock Purchase Plan (the "1994
Plan") which authorizes the sale of up to 500,000 shares of Common Stock to
officers, directors, key employees and consultants. Under the Plan, the right to
purchase shares at prices ranging from 50% to 85% of market value may be
granted. The Company had a 1989 Stock Purchase Plan (the "1989 Plan") which was
identical to the 1994 Plan except

that it covered 333,333 shares. Upon adoption of the 1994 Plan, the 1989 Plan
was terminated. The plans are administered by the Compensation Committee of the
Board. During the nine months ended September 30, 1996, the Company sold 100,000
unregistered common shares to officers and outside directors. From inception of
the 1989 Plan through September 30, 1996, a total of 488,000 unregistered shares
had been sold, for a total consideration of approximately $2.8 million at prices
equal to 75% of market value at the time of the sale.
 
(9)  BENEFIT PLAN
 
     The Company maintains a 401(K) Plan for the benefit of its employees. The
Plan permits employees to make contributions on a pre-tax salary reduction
basis. The Company makes discretionary contributions to the Plan. Company
contributions for 1995 totaled $346,000.
 
(10)  INCOME TAXES
 
     In 1993, the Company adopted FASB Statement No. 109, "Accounting for Income
Taxes". As permitted by Statement 109, the Company elected not to restate prior
year financial statements. As a result of tax basis in excess of the basis on
the financial statements at January 1, 1993, the Company estimated deferred tax
assets of $2.6 million and deferred tax liabilities of $900,000, for net
deferred tax assets of $1.7 million. Due to uncertainty as to the Company's
ability to realize the tax benefit, a valuation allowance was established for
the full amount of the net deferred tax assets. In 1993 and 1994, income taxes
were reduced from the statutory rate of 34% by approximately $.5 million and $.3
million, respectively, through realization of the valuation allowance that was
established.
 
     During 1993, the Company acquired Mark Resources Corporation, in a taxable
combination accounted for as a purchase. Deferred tax assets of $3.9 million and
a deferred tax liability of $8.1 million were recorded in the transaction.
During 1994, the Company acquired Gillring Oil Company and Grand Banks Energy
Company, taxable combinations accounted for as purchases. Deferred tax assets of
$3.5 million and deferred tax liabilities of $3.4 million were recorded in these
transactions. In late 1994, the Company acquired Red Eagle Resources
Corporation, a taxable combination accounted for as a purchase. Deferred tax
liabilities of $12.3 million and deferred tax assets of $.3 million were
recorded in this transaction. In 1996, the Company acquired Eastern Petroleum
Company in a taxable combination accounted for as a purchase. A net deferred tax
liability of $2.1 million was recorded in the transaction.
 
     For the nine months ended September 30, 1995 and 1996, the Company made a
provision for federal income taxes of $898,000 and $4.4 million, respectively.
At September 30, 1996, the Company had available for federal income tax
reporting purposes net operating loss carryovers of approximately $16.9 million
which are subject to annual limitations as to their utilization and expire
between 1996 and 2010. The Company has alternative minimum tax net operating
loss carryovers of $11.6 million which are subject to annual limitations as to
their utilization and expire from 1996 to 2009. The Company has statutory
depletion carryover of approximately $8.2 million and an alternative minimum tax
credit carryover of $500,000. The statutory depletion carryover and alternative
minimum tax credit carryover are not subject to limitation or expiration.
 
(11)  MAJOR CUSTOMERS
 
     The Company markets its oil and gas production on a competitive basis. The
type of contract under which gas production is sold varies but can generally be
grouped into three categories: (a) life-of-the-well; (b) long-term (1 year or
longer); and (c) short-term contracts which may have a primary term of one year,
but which are cancelable at either party's discretion in 30-120 days.
Approximately 60% of the Company's gas production is currently sold under market
sensitive contracts which do not contain floor price provisions. For the nine
months ended September 30, 1996, no one customer accounted for 10% or more of
the Company's total oil and gas revenues. Management believes that the loss of
any one customer would not have a material adverse effect on the operations of
the Company. Oil is sold on a basis such that the purchaser can be changed

on 30 days notice. The price received is generally equal to a posted price set
by the major purchasers in the area. Oil is sold on a basis of price and
service.
 
     The Company has currently hedged 88% of its oil production through April
1997. These hedges involve fixed price arrangements and other price arrangements
at a variety of prices, floors and caps. Although these hedging activities
provide the Company some protection against falling prices, these activities
also reduce the potential benefits to the Company of price increases above the
levels of the hedges.

(13)  RELATED PARTY TRANSACTIONS
 
     Mr. Edelman, Chairman of the Company, is also an executive officer and
shareholder of Snyder Oil Corporation ("SOCO"). At September 30, 1996, Mr.
Edelman owned 5.7% of the Company's Common Stock. In 1995, the Company acquired
SOCO's interest in certain wells located in Appalachia for $4 million. The price
was determined based on arms-length negotiations through a third-party broker
retained by SOCO. Subsequent to the transaction, the Company and SOCO no longer
hold interests in any of the same properties.
 
     During 1995, the Company incurred fees of $145,000 to the Hawthorne Company
in connection with acquisitions. Mr. Aikman, a director of the Company, is an
executive officer and a principal owner of the Hawthorne Company. The fees were
consistent with those paid by the Company to third parties for similar services.

We believe that our audits provide a reasonable basis for our opinion.
 
     The accompanying statements of revenues and direct operating expenses
reflect the revenues and direct operating expenses attributable to the American
Cometra Interests, as described in Note 1, and are not intended to be a complete
presentation of the revenues and expenses of the American Cometra Interests.
 
     In our opinion, the statements referred to above present fairly the
revenues and direct operating expenses of the American Cometra Interests, as
described in Note 1, for the years ended December 31, 1994 and 1995 and the nine

                      NOTES TO THE STATEMENTS OF REVENUES
                         AND DIRECT OPERATING EXPENSES
1.  GENERAL:
 
  Organization
 
     The accompanying statements present the revenues and direct operating
expenses of certain working and other interests in oil and gas properties and
the Sterling gas plant and related pipeline owned by American Cometra, Inc. (the
"American Cometra Interests") which were purchased by Lomak Petroleum, Inc.
("Lomak"). Such financial statements were derived from the historical records of
the predecessor owner and represent Lomak's interest.
 
  Basis of Presentation
 
     The historical financial statements reflecting financial position, results
of operations and cash flows required by generally accepted accounting
principles are not presented, as such information is neither readily available
on an individual property basis nor meaningful for the American Cometra
Interests. During the periods presented, the American Cometra Interests were not
accounted for as a separate entity. These statements do not include
depreciation, depletion and amortization, general and administrative, interest,
federal income tax expenses, or federal income tax credits allowed under Section
29 of the Internal Revenue Code. Accordingly, the accompanying financial
statements are not intended to be a complete presentation of the results of
operations of the American Cometra Interests in conformity with generally
accepted accounting principles.
 
  Revenue Recognition
 
     Revenues are recognized when oil and gas production is sold. Direct
operating expenses are accrued when services are provided. Netted against
marketing and gas plant operating activities is $9,758,300, $7,700,000 and
$8,156,900 for the years ended December 31, 1994 and 1995 and the nine months
ended September 30, 1996, respectively, relating to costs associated with those
activities.
 
  Use of Estimates
 
     Management has made a number of estimates and assumptions relating to the
reporting of the revenues and direct operating expenses to prepare these
financial statements in conformity with generally accepted accounting
principles. Actual results could differ from those estimates.
 
2.  SALES TO MAJOR CUSTOMERS:
 
     For the years ended December 31, 1994 and 1995, four purchasers accounted
for 33% and 54% of total revenues, respectively. For the nine months ended
September 30, 1996, four purchasers accounted for 60% of total revenues.
 
3.  OIL AND GAS RESERVES INFORMATION (UNAUDITED):
 
     The estimates of the American Cometra Interests in proved oil and gas
reserves, which are located entirely in the United States, are based on
evaluations by an independent petroleum engineer, Netherland, Sewell &
Associates as of September 30, 1996. These reserves were estimated in accordance
with guidelines established by the Securities and Exchange Commission which
require that reserve reports be prepared under existing economic and operating
conditions with no provision for price escalations except by contractual
arrangements. Reserves as of December 31, 1994 and 1995 were derived from the
September 30, 1996 reserve estimates after considering production and drilling
activities.
 
     Lomak's management emphasizes that reserve estimates are inherently
imprecise. Accordingly, the estimates are expected to change as future
information becomes available.

     The "Standardized Measure of Discounted Future Net Cash Flows Relating to
Proved Oil and Gas Reserves" (Standardized Measure) is a disclosure requirement
under Statement of Financial Accounting Standards No. 69. The Standardized
Measure does not purport to present the fair market value of proved oil and gas
reserves. This would require consideration of expected future economic and
operating conditions, which are not taken into account in calculating the
Standardized Measure.
 
     Future cash inflows were estimated by applying September 30, 1996 prices,
adjusted for fixed and determinable escalations to the estimated future
production less estimated future production costs based on period-end costs and
future development costs. Future net cash inflows were discounted using a 10%
annual discount rate to arrive at the Standardized Measure. Future income tax
estimates are not included, as the historical tax basis of the properties is not
relevant.

The    % Senior Subordinated Notes due 2007 (the "Notes") are being offered (the
"Notes Offering") by Lomak Petroleum, Inc., a Delaware corporation ("Lomak" or
the "Company"). The Company's payment obligations under the Notes will be
jointly, severally and unconditionally guaranteed (the "Guarantees") on a senior
subordinated basis by each Subsidiary of the Company and any future Subsidiary
of the Company (the "Subsidiary Guarantors").
 
Interest on the Notes will accrue at the rate of     % per annum and will be
payable semi-annually in arrears on         and         of each year, commencing
on            , 1997. The Notes mature on            , 2007, unless previously
redeemed. The Notes will be subject to redemption at the option of the Company,
in whole or in part, on or after            , 2002, at the redemption prices set
forth herein, plus accrued and unpaid interest, if any, thereon to the
applicable redemption date. Upon the occurrence of a Change of Control (as
defined), the Company will be required to offer to repurchase all or a portion
of each Holder's Notes at an offer price in cash equal to 101% of the aggregate
principal amount of such Notes plus accrued and unpaid interest, if any, thereon
to the date of repurchase. Prior to            , 2000, the Company may, at its
option, on any one or more occasions, redeem up to 33 1/3% of the original
aggregate principal amount of the Notes at a redemption price equal to     % of
the principal amount thereof, plus accrued and unpaid interest, if any, thereon
to the redemption date, with all or a portion of the net proceeds of public
sales of Common Stock of the Company. See "Description of Notes."
 
Concurrently with the Notes Offering, the Company is offering 4,000,000 shares
of its Common Stock (the "Common Stock Offering" and together with the Notes
Offering, the "Offerings") by a separate prospectus. The closing of the Notes
Offering and the Common Stock Offering are contingent upon each other. Neither
the Notes Offering nor the Common Stock Offering will be completed until after
the Cometra Acquisition (as defined herein) has been consummated.
 
The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to Senior Debt (as defined) of the Company,
which will include borrowings under the Credit Facility (as defined herein). As
of September 30, 1996, after giving pro forma effect to the Offerings, the
application of the proceeds therefrom, as described under "Use of Proceeds," and
the consummation of the Cometra Acquisition, the principal amount of Senior Debt
outstanding would have been $238 million, which represents borrowings under the
Credit Facility (as defined herein). The Company also has $55 million principal
amount outstanding of 6% Convertible Subordinated Debentures due 2007, which are
expressly subordinated to the Notes.
 
The Company does not intend to apply for listing of the Notes on any securities
exchange or inclusion of the Notes in any automated quotation system.

                                 accrued and unpaid interest thereon to the

                                 to             , 2000, the Company may, at its

                                 the principal amount thereof, plus accrued and
                                 unpaid interest, if any, to the redemption
                                 date, with all or a portion of the net proceeds
                                 of public sales of Common Stock of the Company;
                                 provided that at least 66 2/3% of the original
                                 aggregate principal amount of the Notes remains
                                 outstanding immediately after the occurrence of
                                 such redemption. See "Description of the
                                 Notes -- Optional Redemption."
 
CHANGE OF CONTROL.............   Upon the occurrence of a Change of Control, the
                                 Company will generally be required to offer to
                                 repurchase all or a portion of each Holder's
                                 Notes, at an offer price in cash equal to 101%
                                 of the aggregate principal amount of such
                                 Notes, plus accrued and unpaid interest, if
                                 any, to the date of repurchase, and to
                                 repurchase all Notes tendered pursuant to such
                                 offer. The Credit Facility will prohibit the
                                 Company from repurchasing any Notes pursuant to
                                 a Change of Control offer prior to the
                                 repayment in full of the Senior Debt under the
                                 Credit Facility. Therefore, if a Change of
                                 Control were to occur, there can be no
                                 assurance that the Company or the Subsidiary
                                 Guarantors will have the financial resources or
                                 be permitted under the terms of their
                                 indebtedness to repurchase the Notes. If any
                                 Event of Default (as defined) occurs, the
                                 applicable trustee or holders of at least 25%
                                 in principal amount of the applicable Notes
                                 then outstanding may declare the principal of
                                 and the accrued and unpaid interest on such
                                 Notes to be due and payable immediately.
                                 However, such repayment would be subject to
                                 certain subordination provisions in the
                                 Indenture. See "Risk Factors-Risks Relating to
                                 a Change of Control" and "Description of the
                                 Notes--Subordination" and "--Repurchase at the
                                 Option of Holders--Change of Control," and
                                 "--Events of Default and Remedies."
 
RANKING.......................   The Notes will be general, unsecured
                                 obligations of the Company, will be
                                 subordinated in right of payment to Senior Debt
                                 of the Company, which includes borrowings under
                                 the Credit Facility and any other permitted
                                 indebtedness which does not expressly provide
 
                                       A-3
<PAGE>   97
 
                                 that it is on a parity with or subordinated in
                                 right of payment to the Notes. The claims of
                                 the holders of the Notes will be subordinated
                                 to Senior Debt, which, as of September 30,
                                 1996, on a pro forma basis after giving effect
                                 to the Offerings and the application of the
                                 proceeds therefrom, would have been
                                 approximately $238 million, which represents
                                 borrowings under the Credit Facility. See
                                 "Capitalization," "Description of the
                                 Notes-Subordination" and "Description of
                                 Capital Stock and Indebtedness--Credit
                                 Facility."
 
SUBSIDIARY GUARANTEES.........   The Company's payment obligations under the
                                 Notes will be jointly, severally and
                                 unconditionally guaranteed on a senior
                                 subordinated basis (the "Guarantees") by each
                                 Subsidiary of the Company and any future
                                 Subsidiary of the Company. The Guarantees will
                                 be subordinated to Senior Debt of the
                                 Subsidiary Guarantors to the same extent and in
                                 the same manner as the Notes are subordinated
                                 to Senior Debt. See "Description of the Notes-
                                 Guarantees" and "Description of Capital Stock
                                 and Indebtedness -- Credit Facility."
 
CERTAIN COVENANTS.............   The Notes will be issued pursuant to an
                                 indenture (the "Indenture") containing certain
                                 covenants that will, among other things, limit
                                 the ability of the Company and its Subsidiaries
                                 to incur additional indebtedness and issue
                                 Disqualified Stock, pay dividends, make
                                 distributions, make investments, make certain
                                 other Restricted Payments, enter into certain
                                 transactions with affiliates, dispose of
                                 certain assets, incur liens securing
                                 Indebtedness (as defined) of any kind (other
                                 than Permitted Liens, as defined) and engage in
                                 mergers and consolidations. See "Description of
                                 the Notes--Certain Covenants."
 
USE OF PROCEEDS...............   The Company will use the proceeds of the Notes
                                 Offering and the Common Stock Offering to repay
                                 a portion of the indebtedness incurred to fund
                                 the purchase price for the Cometra Properties.
                                 See "Use of Proceeds."
 
                                  RISK FACTORS
 
     See "Risk Factors" for a discussion of certain factors that should be
considered in connection with an investment in the Notes offered hereby,
including information regarding the Company's highly leveraged capital
structure, the uncertainty of oil and gas prices and certain risks associated
with an investment in the Notes offered hereby.
 
                                       A-4
<PAGE>   98
 
[NOTE: THESE RISK FACTORS SUPPLEMENT THE RISK FACTORS CONTAINED IN THE COMMON
STOCK PROSPECTUS.]
 
SUBORDINATION OF NOTES
 
     The Notes will be subordinated in right of payment to all existing and
future Senior Debt of the Company, including borrowings under the Credit
Facility. In the event of bankruptcy, liquidation or reorganization of the
Company, the assets of the Company will be available to pay obligations on the
Notes only after all Senior Debt has been paid in full, and there may not be
sufficient assets remaining to pay amounts due on any or all of the Notes
outstanding. The aggregate principal amount of Senior Debt of the Company, as of
September 30, 1996, would have been $238 million on a pro forma basis.
Additional Senior Debt may be incurred by the Company from time to time, subject
to certain restrictions. In addition to being subordinated to all existing and
future Senior Debt of the Company, the Notes will not be secured by any of the
Company's assets, unlike the borrowings under the Credit Facility. See
"Description of Notes--Subordination."
 
FRAUDULENT CONVEYANCE
 
     The incurrence of indebtedness (such as the Notes) in connection with the
financing and refinancing of the Cometra Acquisition is subject to review under
relevant federal and state fraudulent conveyance statutes in a bankruptcy or
reorganization case or a lawsuit by or on behalf of other creditors of the
Company. The Company's obligations under the Notes will be guaranteed on a
senior subordinated basis by its subsidiaries. To the extent that a court were
to find that (x) the Notes or a Subsidiary Guarantee was incurred with the
intent to hinder, delay or defraud any present or future creditor or that the
Company or such Subsidiary Guarantor contemplated insolvency with a design to
favor one or more creditors to the exclusion in whole or in part of others or
(y) the Company or a Subsidiary Guarantor did not receive fair consideration or
reasonably equivalent value for issuing the Notes or Subsidiary Guarantee and,
at the time thereof, the Company or such Subsidiary Guarantor (i) was insolvent
or rendered insolvent by reason of the issuance of the Notes or the Subsidiary
Guarantee, (ii) was engaged or about to engage in a business or transaction for
which its remaining assets constituted unreasonably small capital or (iii)
intended to incur, or believed that it would incur, debts beyond its ability to
pay such debts as they matured, a court could avoid or subordinate the Notes or
Subsidiary Guarantee in favor of other creditors. Among other things, a legal
challenge of the Subsidiary Guarantee issued by such Subsidiary Guarantor on
fraudulent conveyance grounds may focus on the benefits, if any, realized by
such Subsidiary Guarantor as a result of the issuance by the Company of the
Notes. To the extent the Subsidiary Guarantee issued by a Subsidiary Guarantor
is voided as a fraudulent conveyance or held unenforceable for any other reason,
the Holders of the Notes would cease to have any claim in respect of such
Subsidiary Guarantor and would be creditors solely of the Company and any other
Subsidiary Guarantors.
 
     On the basis of historical financial information, recent operating history
as discussed in "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and other information currently available to it, the
Company believes that the Notes and the Subsidiary Guarantees issued
concurrently with the issuance of the Notes are being incurred for proper
purposes and in good faith and that, after giving effect to Indebtedness
incurred in connection with the issuance of the Notes and the issuance of the
Subsidiary Guarantees, the Company and the Subsidiary Guarantors are solvent,
will have sufficient capital for carrying on their respective businesses and
will be able to pay their debts as such debts become absolute and mature. There
can be no assurance, however, that a court passing on such questions would reach
the same conclusions.
 
ABSENCE OF A PUBLIC MARKET FOR NOTES
 
     There is no existing market for the Notes and, although the Underwriters
have advised the Company that they currently intend to make a market in the
Notes, the Underwriters are not obligated to do so and may discontinue such
market making at any time. The Company does not intend to apply for listing of
the Notes on a securities exchange or to seek approval for quotation through an
automated quotation system. Accordingly, there can be no assurance that an
active market will develop upon completion of the Notes Offering or, if
developed, that such market will be sustained or as to the liquidity of any
market. The initial offering price of
 
                                       A-5
<PAGE>   99
 
the Notes will be determined through negotiations between the Company and the
Underwriters, and may bear no relationship to the market price of the Notes
after the Notes Offering. Factors such as quarterly or cyclical variations in
the Company's financial results, variations in interest rates, future
announcements concerning the Company or its competitors, government regulation,
general economic and other conditions and developments affecting the oil and gas
industry could cause the market price of the Notes to fluctuate substantially.
 
RISKS RELATING TO A CHANGE OF CONTROL
 
     Upon a Change of Control (as defined herein), holders of the Notes will
have the right to require the Company to repurchase all or any part of such
holders' Notes at a price equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of repurchase. The events that
constitute a Change of Control hereunder would constitute a default under the
Credit Facility, which prohibits the purchase of the Notes by the Company in the
event of certain Change of Control events unless and until such time as the
Company's indebtedness under the Credit Facility is repaid in full. There can be
no assurance that the Company and the Subsidiary Guarantors would have
sufficient financial resources available to satisfy all of its or their
obligations under the Credit Facility and the Notes in the event of a Change of
Control. The Company's failure to purchase the Notes would result in a default
under the Indenture and under the Credit Facility, each of which could have
adverse consequences for the Company and the holders of the Notes. See
"Description of Capital Stock and Indebtedness" and "Description of the Notes
- -- Repurchase at the Option of Holders -- Change of Control." The definition of
"Change of Control" in the Indenture includes a sale, lease, conveyance or other
disposition of "all or substantially all" of the assets of the Company and its
Subsidiaries taken as a whole to a person or group of persons. There is little
case law interpreting the phrase "all or substantially all" in the context of an
indenture. Because there is no precise established definition of this phrase,
the ability of a holder of the Notes to require the Company to repurchase such
Notes as a result of a sale, lease, conveyance or transfer of all or
substantially all of the Company's assets to a person or group of persons may be
uncertain.

                                USE OF PROCEEDS
 
     The net proceeds of the Notes Offering are estimated to be approximately
$96.7 million and the net proceeds of the Common Stock Offering are estimated to
be approximately $79.3 million (assuming an offering of $21 per share), after
deducting underwriting discounts and estimated expenses. The Company intends to
use all of such net proceeds to repay certain indebtedness incurred under the
Credit Facility to fund a portion of the cash purchase price for the Cometra
Properties. See "Cometra Acquisition." As of December 31, 1996, indebtedness
under the Credit Facility, which expires in January, 2002, had a weighted
average interest rate of 6.7%. For additional information with respect to the
interest rates, maturity and covenants related to the Credit Facility, see
"Description of Capital Stock and Indebtedness -- Credit Facility."

                            DESCRIPTION OF THE NOTES
 
GENERAL
 
     The Senior Subordinated Notes (the "Notes") will be issued pursuant to an
Indenture (the "Indenture") among the Company, the Subsidiary Guarantors and
                         , as trustee (the "Trustee"). Copies of the Indenture
are filed as exhibits to the Registration Statement of which this Prospectus
forms a part and will be made available to prospective purchasers of the Notes
upon request. The Indenture is subject to and governed by the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act"). The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Notes are subject to all such terms,
and Holders of the Notes are referred to the Indenture and the Trust Indenture
Act for a statement thereof. The following summary of certain provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture, including the definitions therein of certain terms
used below. The definitions of certain terms used in the following summary are
set forth below under "-- Certain Definitions."
 
     The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to Senior Debt. The Notes will be guaranteed on
a senior subordinated basis by each of the Subsidiaries of the Company and any
future Subsidiary of the Company. The obligations of the Subsidiary Guarantors
under the Guarantees will be general unsecured obligations of each of the
Subsidiary Guarantors and will be subordinated in right of payment to all
obligations of the Subsidiary Guarantors in respect of Senior Debt. See "--
Guarantees" and "Risk Factors -- Subordination."
 
     For purposes of this section, the term "Company" means Lomak Petroleum,
Inc.
 
SUBORDINATION
 
     The payment of principal of, premium, if any, and interest on the Notes and
any other payment obligations of the Company in respect of the Notes (including
any obligation to repurchase the Notes) will be subordinated in certain
circumstances in right of payment, as set forth in the Indenture, to the prior
payment in full in cash of all Senior Debt, whether outstanding on the date of
the Indenture or thereafter incurred.
 
     Upon any payment or distribution of property or securities to creditors of
the Company in a liquidation or dissolution of the Company or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or its property, or in an assignment for the benefit of creditors or any
marshalling of the Company's assets and liabilities, the holders of Senior Debt
will be entitled to receive payment in full of all Obligations due in respect of
such Senior Debt (including interest after the commencement of any such
proceeding at the rate specified in the applicable Senior Debt, whether or not a
claim for such interest would be allowed in a proceeding) before the Holders of
the Notes will be entitled to receive any payment with respect to the Notes, and
until all Obligations with respect to Senior Debt are paid in full, any
distribution to which the Holders of the Notes would be entitled shall be made
to the holders of Senior Debt (except that Holders of the Notes may receive
payments made from the trust described under "-- Legal Defeasance and Covenant
Defeasance").
 
     The Company also may not make any payment (whether by redemption, purchase,
retirement defeasance or otherwise) upon or in respect of the Notes (except from
the trust described under "-- Legal Defeasance and Covenant Defeasance") if (i)
a default in the payment of the principal of, premium, if any, or interest on
Designated Senior Debt occurs or (ii) any other default occurs and is continuing
with respect to Designated Senior Debt that permits, or with the giving of
notice or passage of time or both (unless cured or waived) will permit, holders
of the Designated Senior Debt as to which such default relates to accelerate its
maturity and the Trustee receives a notice of such default (a "Payment Blockage
Notice") from the Company or the holders of any Designated Senior Debt. Cash
payments on the Notes shall be resumed (a) in the case of a payment default,
upon the date on which such default is cured or waived and (b) in case of a
nonpayment default, the earlier of the date on which such nonpayment default is
cured or waived or 90 days after the date on which the applicable Payment
Blockage Notice is received, unless the maturity of any Designated Senior Debt
has been accelerated or a default of the type described in clause (ix) under the
caption "Events of
 
                                       A-8
<PAGE>   102
 
Default" has occurred and is continuing. No new period of payment blockage may
be commenced unless and until 360 days have elapsed since the date of
commencement of the payment blockage period resulting from the immediately prior
Payment Blockage Notice. No nonpayment default in respect of Designated Senior
Debt that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent
Payment Blockage Notice.
 
     The Indenture will further require that the Company promptly notify holders
of Senior Debt if payment of the Notes is accelerated because of an Event of
Default.
 
     As a result of the subordination provisions described above, in the event
of a liquidation or insolvency of the Company, Holders of the Notes may recover
less ratably than creditors of the Company who are holders of Senior Debt. On a
pro forma basis, after giving effect to the Cometra Acquisition, the related
financing transactions and the application of the proceeds therefrom, the
principal amount of Senior Debt outstanding at September 30, 1996 would have
been approximately $  million, which includes $  million of borrowings under the
Credit Agreement. See "Description of Capital Stock and Indebtedness." The
Indenture will limit, subject to certain financial tests, the amount of
additional Indebtedness, including Senior Debt, that the Company and its
Subsidiaries can incur. See "-- Certain Covenants -- Incurrence of Indebtedness
and Issuance of Disqualified Stock."
 
GUARANTEES
 
     The Company's payment obligations under the Notes will be jointly,
severally and unconditionally guaranteed (the "Guarantees") by each Subsidiary
of the Company and any future Subsidiary of the Company. The Guarantees will be
subordinated to Indebtedness of the Subsidiary Guarantors to the same extent and
in the same manner as the Notes are subordinated to the Senior Debt. Each
Guarantee by a Subsidiary Guarantor will be limited in an amount not to exceed
the maximum amount that can be guaranteed by the applicable Subsidiary Guarantor
without rendering such Guarantee, as it relates to such Subsidiary Guarantor,
voidable under applicable law relating to fraudulent conveyance or fraudulent
transfer or similar laws affecting rights of creditors generally.
 
     The Indenture will provide that no Subsidiary Guarantor may consolidate
with or merge with or into (whether or not such Subsidiary Guarantor is the
surviving Person), another Person whether or not affiliated with such Subsidiary
Guarantor, unless (i) subject to the provisions of the following paragraph, the
Person formed by or surviving any such consolidation or merger (if other than
such Subsidiary Guarantor) assumes all the obligations of such Subsidiary
Guarantor pursuant to a supplemental indenture in form and substance reasonably
satisfactory to the Trustee in respect of the Notes, the Indenture and the
Guarantees; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; and (iii) such transaction does not violate any of
the covenants described under the heading "-- Certain Covenants."
 
     The Indenture will provide that in the event of a sale or other disposition
of all or substantially all of the assets of a Subsidiary Guarantor to a third
party in a transaction that does not violate any of the covenants in the
Indenture, by way of merger, consolidation or otherwise, or a sale or other
disposition of all of the capital stock of a Subsidiary Guarantor, then such
Subsidiary Guarantor (in the event of a sale or other disposition, by way of
such a merger, consolidation or otherwise, of all of the capital stock of such
Subsidiary Guarantor) or the Person acquiring the property (in the event of a
sale or other disposition of all or substantially all of the assets of such
Subsidiary Guarantor) will be released from and relieved of any obligations
under its Guarantee; provided that the Net Proceeds of such sale or other
disposition are applied in accordance with the covenant described under the
caption "-- Repurchase at the Option of Holders -- Asset Sales."
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Notes will be limited in aggregate principal amount to $100.00 million
and will mature on             , 2007. Interest on the Notes will accrue at the
rate of  % per annum and will be payable semi-annually in arrears
on          -          and          -          of each year, commencing on
            , 1997, to Holders of the Notes of record on the immediately
preceding        and        . Interest on the
 
                                       A-9
<PAGE>   103
 
Notes will accrue from the most recent date on which interest has been paid or,
if no interest has been paid, from the date of original issuance.
 
     Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months. Principal, premium, if any, and interest on the Notes will
be payable at the office or agency of the Company maintained for such purpose
within the City and State of New York or, at the option of the Company, payment
of interest may be made by check mailed to the Holders of the Notes at their
respective addresses set forth in the applicable register of Holders of the
Notes. Until otherwise designated by the Company, the Company's office or agency
in New York will be the office of the Trustee maintained for such purpose. The
Notes will be fully registered as to principal and interest in minimum
denominations of $1,000 and integral multiples of $1,000 in excess thereof.
 
OPTIONAL REDEMPTION
 
     Except as otherwise described below, the Notes will not be redeemable at
the Company's option prior to             , 2002. Thereafter, the Notes will be
subject to redemption at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest thereon to the applicable redemption date, if redeemed during
the twelve-month period beginning on             of the years indicated below:

</TABLE>
 
     Prior to             , 2000, the Company may, at its option, on any one or
more occasions, redeem up to 33 1/3% of the original aggregate principal amount
of the Notes at a redemption price equal to   % of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the redemption date, with
all or a portion of the net proceeds of public sales of Common Stock of the
Company; provided that at least 66 2/3% of the original aggregate principal
amount of the Notes remains outstanding immediately after the occurrence of such
redemption; and provided, further, that such redemption shall occur within 60
days of the date of the closing of the related sale of Common Stock of the
Company.
 
SELECTION AND NOTICE
 
     In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Notes are
listed, or, if such Notes are not so listed, on a pro rata basis, by lot or by
such method as such Trustee shall deem fair and appropriate; provided that no
Note of $1,000 or less shall be redeemed in part. Notices of redemption shall be
mailed by first class mail at least 30 but not more than 60 days before the
redemption date to each Holder of the Notes to be redeemed at its registered
address. If any Note is to be redeemed in part only, the notice of redemption
that relates to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. On and after the redemption date, interest
will cease to accrue on the Notes or portions of them called for redemption.
 
MANDATORY REDEMPTION
 
     Except as set forth below under "-- Repurchase at the Option of Holders,"
the Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes.

REPURCHASE AT THE OPTION OF HOLDERS
 
  Change of Control
 
     Upon the occurrence of a Change of Control, each Holder of the Notes will
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of such Holder's Notes pursuant to the
offer described below (the "Change of Control Offer") at an offer price in cash
equal to 101% of the aggregate principal amount of the Notes plus accrued and
unpaid interest, if any, thereon to the date of purchase (the "Change of Control
Payment"). Within 30 days following any Change of Control, the Company will (i)
mail a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and offer to repurchase the Notes pursuant to
the procedures required by the Indenture and described in such notice and (ii)
(a) offer to repay in full all Obligations under the Credit Agreement and to
repay in full all Obligations of each lender who has accepted such offer or (b)
obtain the requisite consent under the Credit Agreement to permit the purchase
of the Notes as described herein. The Company will comply with the requirements
of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in
connection with the repurchase of the Notes as a result of a Change of Control.
 
     On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all the Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the relevant Notes so accepted together with an Officers' Certificate
stating the aggregate principal amount of such Notes or portions thereof being
purchased by the Company. The Paying Agent will promptly mail to each Holder of
the Notes so tendered the Change of Control Payment for such Notes, and the
Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided that each such new Note will
be in a principal amount of $1,000 or an integral multiple thereof. The
Indenture will provide that, prior to complying with the provisions of this
covenant, but in any event within 90 days following a Change of Control, the
Company will either repay all outstanding Senior Debt or obtain the requisite
consents, if any, under all agreements governing outstanding Senior Debt to
permit the repurchase of the Notes required by this covenant. The Company will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.
 
     Except as described above with respect to a Change of Control, the
Indenture will not contain provisions that permit the Holders of the Notes to
require that the Company repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction.
 
     The Company will not be required to make a Change of Control Offer if a
third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in the Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.
 
     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of the Notes to require the Company to
repurchase such Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.
 
  Asset Sales
 
     The Indenture will provide that the Company will not, and will not permit
any of its Subsidiaries to, engage in an Asset Sale unless (i) the Company or
the Subsidiary, as the case may be, receives consideration at the time of such
Asset Sale at least equal to the fair market value (as determined in good faith
by a
 
                                      A-11
<PAGE>   105
 
resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Trustee, which determination shall be conclusive evidence of
compliance with this provision) of the assets or Equity Interests issued or sold
or otherwise disposed of and (ii) at least 85% of the consideration therefor
received by the Company or such Subsidiary is in the form of cash or Cash
Equivalents; provided that the amount of (x) any liabilities (as shown on the
Company's or such Subsidiary's most recent balance sheet), of the Company or any
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any guarantee thereof) that are assumed by
the transferee of any such assets pursuant to a customary novation agreement
that releases the Company or such Subsidiary from further liability and (y) any
non-cash consideration received by the Company or any such Subsidiary from such
transferee that is converted by the Company or such Subsidiary into cash within
180 days of closing such Asset Sale, shall be deemed to be cash for purposes of
this provision (to the extent of the cash received).
 
     Within 180 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, (a) to reduce Senior
Debt or (b) to acquire a controlling interest in another Oil and Gas Business,
to make capital expenditures in respect of the Company's or its Subsidiaries'
Oil and Gas Business, or to purchase long-term assets that are used or useful in
the Oil and Gas Business. Pending the final application of any such Net
Proceeds, the Company may temporarily reduce Senior Debt that is revolving debt
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds from Asset Sales that are not applied as
provided in the first sentence of this paragraph will (after the expiration of
the periods specified in this paragraph) be deemed to constitute "Excess
Proceeds."
 
     When the aggregate amount of Excess Proceeds exceeds $5 million, the
Company will be required to make an offer to all Holders of the Notes and, to
the extent required by the terms thereof, to all holders or lenders of Pari
Passu Indebtedness (an "Asset Sale Offer") to purchase the maximum principal
amount of the Notes and any such Pari Passu Indebtedness to which the Asset Sale
Offer applies that may be purchased out of the Excess Proceeds, at an offer
price in cash equal to 100% of the principal amount thereof plus accrued and
unpaid interest thereon to the date of purchase, in accordance with the
procedures set forth in the Indenture or the agreements governing the Pari Passu
Indebtedness, as applicable. To the extent that the aggregate principal amount
of the Notes and Pari Passu Indebtedness tendered pursuant to an Asset Sale
Offer is less than the Excess Proceeds, the Company may use any remaining Excess
Proceeds for general corporate purposes. If the aggregate principal amount of
the Notes surrendered by Holders thereof and other Pari Passu Indebtedness
surrendered by holders or lenders thereof, collectively, exceeds the amount of
Excess Proceeds, the Trustee shall select the Notes and Pari Passu Indebtedness
to be purchased on a pro rata basis, based on the aggregate principal amount
thereof surrendered in such Asset Sale Offer. Upon completion of such Asset Sale
Offer, the amount of Excess Proceeds shall be reset at zero.
 
     The Credit Agreement may prohibit the Company from purchasing any Notes and
also provides that certain change of control events with respect to the Company
would constitute a default thereunder. Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control or
Asset Sale Offer occurs at a time when the Company is prohibited from purchasing
the Notes, the Company could seek the consent of its lenders to the purchase or
could attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings, the Company may
remain prohibited from purchasing the Notes. In such case, the Company's failure
to purchase tendered Notes would constitute an Event of Default under the
Indenture which would, in turn, constitute a default under the Credit Agreement.
In such circumstances, the subordination provisions in the Indenture would
likely restrict payments to the Holders of the Notes.
 
CERTAIN COVENANTS
 
  Restricted Payments
 
     The Indenture will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly: (i) declare or pay any
dividend or make any other payment or distribution on account of the Company's
Equity Interests (including, without limitation, any payment in connection with
any merger or
 
                                      A-12
<PAGE>   106
 
consolidation involving the Company) to the direct or indirect holders of the
Company's Equity Interests in their capacity as such (other than dividends or
distributions payable in Equity Interests (other than Disqualified Stock) of the
Company); (ii) purchase, redeem or otherwise acquire or retire for value any
Equity Interests of the Company or any direct or indirect parent or other
Affiliate of the Company that is not a Subsidiary of the Company; (iii) make any
principal payment on, or purchase, redeem, defease or otherwise acquire or
retire for value any Indebtedness that is subordinated to the Notes, except at
final maturity; or (iv) make any Restricted Investment (all such payments and
other actions set forth in clauses (i) through (iv) above being collectively
referred to as "Restricted Payments"), unless, at the time of and after giving
effect to such Restricted Payment:
 
          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and
 
          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     the covenant described below under the caption "-- Incurrence of
     Indebtedness and Issuance of Disqualified Stock"; and
 
          (c) such Restricted Payment, together with the aggregate of all other
     Restricted Payments made by the Company and its Subsidiaries after the date
     of the Indenture (excluding Restricted Payments permitted by clauses (2),
     (3), (5), (6) and (7) of the next succeeding paragraph), is less than the
     sum of (i) 50% of the Consolidated Net Income of the Company for the period
     (taken as one accounting period) from the beginning of the first fiscal
     quarter commencing after the date of the Indenture to the end of the
     Company's most recently ended fiscal quarter for which internal financial
     statements are available at the time of such Restricted Payment (or, if
     such Consolidated Net Income for such period is a deficit, less 100% of
     such deficit), plus (ii) 100% of the aggregate net cash proceeds received
     by the Company from the issue or sale since the date of the Indenture of
     Equity Interests of the Company or of debt securities of the Company that
     have been converted into or exchanged for such Equity Interests (other than
     Equity Interests (or convertible debt securities) sold to a Subsidiary of
     the Company and other than Disqualified Stock or debt securities that have
     been converted into Disqualified Stock), plus (iii) to the extent that any
     Restricted Investment that was made after the date of the Indenture is sold
     for cash or otherwise liquidated or repaid for cash, the lesser of (A) the
     net proceeds of such sale, liquidation or repayment and (B) the initial
     amount of such Restricted Investment, provided, however, that the foregoing
     provisions of this paragraph (c) will not prohibit Restricted Payments in
     an aggregate amount not to exceed $10 million.
 
     The foregoing provisions will not prohibit (1) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (2) the redemption, repurchase, retirement or other acquisition of
any Equity Interests of the Company in exchange for, or out of the proceeds of,
the substantially concurrent sale (other than to a Subsidiary of the Company) of
other Equity Interests of the Company (other than any Disqualified Stock);
provided that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition shall be excluded
from clause (c)(ii) of the preceding paragraph; (3) the defeasance, redemption
or repurchase of subordinated Indebtedness with the net cash proceeds from an
incurrence of subordinated Permitted Refinancing Debt or the substantially
concurrent sale (other than to a Subsidiary of the Company) of Equity Interests
of the Company (other than Disqualified Stock); provided that the amount of any
such net cash proceeds that are utilized for any such redemption, repurchase,
retirement or other acquisition shall be excluded from clause (c)(ii) of the
preceding paragraph; (4) the repurchase, redemption or other acquisition or
retirement for value of any Equity Interests of the Company or any Subsidiary of
the Company held by any of the Company's (or any of its Subsidiaries') employees
pursuant to any management equity subscription agreement or stock option
agreement in effect as of the date of the Indenture; provided that the aggregate
price paid for all such repurchased, redeemed, acquired or retired Equity
Interests shall not exceed $1 million in any twelve-month period; and provided
further that no Default or Event of Default shall have occurred and be
continuing immediately after such transaction; (5) repurchases
 
                                      A-13
<PAGE>   107
 
of Equity Interests deemed to occur upon exercise of stock options if such
Equity Interests represent a portion of the exercise price of such options; (6)
the redemption of the Company's 6% Convertible Subordinated Debentures Due
February 1, 2007; provided that the average closing price of the Company's
common stock for the 30 trading days prior to the date of such redemption is
greater than 120% of the conversion price and (7) conversion of the Company's
$2.03 Convertible Preferred Stock in accordance with its terms.
 
     The amount of all Restricted Payments (other than cash) shall be the fair
market value (as determined in good faith by a resolution of the Board of
Directors set forth in an Officers' Certificate delivered to the Trustee, which
determination shall be conclusive evidence of compliance with this provision) on
the date of the Restricted Payment of the asset(s) proposed to be transferred by
the Company or the applicable Subsidiary, as the case may be, pursuant to the
Restricted Payment. Not later than five days after the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "Restricted
Payments" were computed.
 
  Incurrence of Indebtedness and Issuance of Disqualified Stock
 
     The Indenture will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt) and that the Company will not issue any
Disqualified Stock and will not permit any of its Subsidiaries to issue any
shares of preferred stock; provided, however, that the Company may incur
Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock if:
 
          (i) the Fixed Charge Coverage Ratio for the Company's most recently
     ended four full fiscal quarters for which internal financial statements are
     available immediately preceding the date on which such additional
     Indebtedness is incurred or such Disqualified Stock is issued would have
     been at least 2.5 to 1, determined on a pro forma basis as set forth in the
     definition of Fixed Charge Coverage Ratio; and
 
          (ii) no Default or Event of Default shall have occurred and be
     continuing at the time such additional Indebtedness is incurred or such
     Disqualified Stock is issued or would occur as a consequence of the
     incurrence of the additional Indebtedness or the issuance of the
     Disqualified Stock.
 
     Notwithstanding the foregoing, the Indenture will not prohibit any of the
following (collectively, "Permitted Indebtedness"): (a) the Indebtedness
evidenced by the Notes; (b) the incurrence by the Company of Indebtedness
pursuant to Credit Facilities, so long as the aggregate principal amount of all
Indebtedness outstanding under all Credit Facilities does not, at any one time,
exceed the lesser of (i) $500 million (or, if there is any permanent reduction
in the aggregate principal amount permitted to be borrowed under the Credit
Agreement, such lesser aggregate principal amount) and (ii) the Borrowing Base;
(c) the guarantee by any Subsidiary Guarantor of any Indebtedness that is
permitted by the Indenture to be incurred by the Company; (d) all Indebtedness
of the Company and its Subsidiaries in existence as of the date of the Indenture
after giving effect to the Cometra Acquisition, the related financing
transactions and the application of the proceeds thereof; (e) intercompany
Indebtedness between or among the Company and any of its Wholly Owned
Subsidiaries; provided, however, that (i) if the Company is the obligor on such
Indebtedness, such Indebtedness is expressly subordinate to the payment in full
of all Obligations with respect to the Notes and (ii)(A) any subsequent issuance
or transfer of Equity Interests that results in any such Indebtedness being held
by a Person other than the Company or a Wholly Owned Subsidiary and (B) any sale
or other transfer of any such Indebtedness to a Person that is not either the
Company or a Wholly Owned Subsidiary shall be deemed, in each case, to
constitute an incurrence of such Indebtedness by the Company or such Subsidiary,
as the case may be; (f) Indebtedness in connection with one or more standby
letters of credit, guarantees, performance bonds or other reimbursement
obligations, in each case, issued in the ordinary course of business and not in
connection with the borrowing of money or the obtaining of advances or credit
(other than advances or credit on open account, includible in current
liabilities, for goods and services in the ordinary course of business and on
terms and conditions which are customary in the Oil and Gas Business, and other
than the extension of credit represented by such letter of credit, guarantee or
performance bond itself), not to
 
                                      A-14
<PAGE>   108
 
exceed in the aggregate at any given time 5% of Total Assets; (g) Indebtedness
under Interest Rate Hedging Agreements entered into for the purpose of limiting
interest rate risks, provided that the obligations under such agreements are
related to payment obligations on Indebtedness otherwise permitted by the terms
of this covenant and that the aggregate notional principal amount of such
agreements does not exceed the principal amount of the Indebtedness to which
such agreements relate; (h) Indebtedness under Oil and Gas Hedging Contracts,
provided that such contracts were entered into in the ordinary course of
business for the purpose of limiting risks that arise in the ordinary course of
business of the Company and its Subsidiaries; (i) the incurrence by the Company
of Indebtedness not otherwise permitted to be incurred pursuant to this
paragraph, provided that the aggregate principal amount of all Indebtedness
incurred pursuant to this clause (i), together with all Permitted Refinancing
Debt incurred pursuant to clause (j) of this paragraph in respect of
Indebtedness previously incurred pursuant to this clause (i), does not exceed $[
] million at any one time outstanding; (j) Permitted Refinancing Debt incurred
in exchange for, or the net proceeds of which are used to refinance, extend,
renew, replace, defease or refund, Indebtedness that was permitted by the
Indenture to be incurred (including Indebtedness previously incurred pursuant to
this clause (j)); (k) accounts payable or other obligations of the Company or
any Subsidiary to trade creditors created or assumed by the Company or such
Subsidiary in the ordinary course of business in connection with the obtaining
of goods or services; (l) Indebtedness consisting of obligations in respect of
purchase price adjustments, guarantees or indemnities in connection with the

     The Indenture will provide that (i) the Company will not incur, create,
issue, assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt and senior in any
respect in right of payment to the Notes and (ii) the Subsidiary Guarantors will
not directly or indirectly incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of

foregoing limitations will not apply to distinctions between categories of
Indebtedness that exist by reason of any Liens arising or created in respect of
some but not all such Indebtedness.
 
  Liens
 
     The Indenture will provide that the Company will not, and will not permit

acquired.
 
  Dividend and Other Payment Restrictions Affecting Subsidiaries
 
     The Indenture will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any encumbrance or restriction on the
ability of any Subsidiary to (i)(x) pay dividends or make any other
distributions to the Company or any of its Subsidiaries (1) on its Capital Stock
or (2) with respect to any other interest or participation in, or measured by,
its profits, or (y) pay any indebtedness owed to the Company or any of its
Subsidiaries, (ii) make loans or advances to the Company or any of its
Subsidiaries or (iii) transfer any of its properties or assets to the Company or

under or by reason of (a) the Credit Agreement as in effect as of the date of
the Indenture, and any amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings thereof or any
other Credit Facility, provided that such amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements,
refinancings or other Credit Facilities are no more restrictive with respect to
such dividend and other payment restrictions than those contained in the Credit
Agreement as in effect on the date of the Indenture, (b) the Indenture and the
Notes, (c) applicable law, (d) any instrument governing Indebtedness or Capital
Stock of a Person acquired by the Company or any of its Subsidiaries as in
effect at the time of such acquisition (except, in the case of Indebtedness, to
the extent
 
                                      A-15
<PAGE>   109
 
such Indebtedness was incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person, other than the Person and its
Subsidiaries, or the property or assets of the Person and its Subsidiaries, so
acquired, provided that, in the case of Indebtedness, such Indebtedness was
permitted by the terms of the Indenture to be incurred, (e) by reason of
customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices, (f) purchase money
obligations for property acquired in the ordinary course of business that impose
restrictions of the nature described in clause (iii) above on the property so
acquired, or (g) Permitted Refinancing Debt, provided that the restrictions
contained in the agreements governing such Permitted Refinancing Debt are no
more restrictive than those contained in the agreements governing the
Indebtedness being refinanced.
 
  Merger, Consolidation, or Sale of Assets
 
     The Indenture will provide that the Company may not consolidate or merge
with or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of its properties or assets, in one or more related transactions, to another
Person, and the Company may not permit any of its Subsidiaries to enter into any
such transaction or series of transactions if such transaction or series of
transactions would, in the aggregate, result in a sale, assignment, transfer,
lease, conveyance, or other disposition of all or substantially all of the
properties or assets of the Company to another Person unless (i) the Company is
the surviving corporation or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made (the "Surviving Entity") is a corporation organized or existing under the
laws of the United States, any state thereof or the District of Columbia; (ii)
the Surviving Entity (if the Company is not the continuing obligor under the
Indenture) assumes all the obligations of the Company under the Notes and the

to the Trustee; (iii) immediately before and after giving effect to such
transaction or series of transactions no Default or Event of Default exists;
(iv) immediately after giving effect to such transaction or a series of
transactions on a pro forma basis (and treating any Indebtedness not previously
an obligation of the Company and its Subsidiaries which becomes the obligation
of the Company or any of its Subsidiaries as a result of such transaction or
series of transactions as having been incurred at the time of such transaction
or series of transactions), the Consolidated Net Worth of the Company and its
Subsidiaries or the Surviving Entity (if the Company is not the continuing
obligor under the Indenture) is equal to or greater than the Consolidated Net
Worth of the Company and its Subsidiaries immediately prior to such transaction
or series of transactions and (v) the Company or the Surviving Entity (if the
Company is not the continuing obligor under the Indenture) will, at the time of
such transaction or series of transactions and after giving pro forma effect
thereto as if such transaction or series of transactions had occurred at the
beginning of the applicable four-quarter period, be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the test set forth in the first
paragraph of the covenant described above under the caption "-- Incurrence of
Indebtedness and Issuance of Disqualified Stock."
 
  Transactions with Affiliates
 
     The Indenture will provide that the Company will not, and will not permit
any of its Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any of
its Affiliates (each of the foregoing, an "Affiliate Transaction"), unless (i)

or the relevant Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Subsidiary with an unrelated
Person and (ii) the Company delivers to the Trustee (a) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving

Transactions involving aggregate consideration in excess of $5.0 million, a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (i) above and
that such Affiliate Transaction has been approved in good faith by a majority of
the members of the Board of Directors who are
 
                                      A-16
<PAGE>   110
 
disinterested with respect to such Affiliate Transaction, which resolution shall
be conclusive evidence of compliance with this provision, and (c) with respect
to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $10.0 million, an opinion as to
the fairness to the Holders of such Affiliate Transaction from a financial point
of view issued by an accounting, appraisal, engineering or investment banking
firm of national standing; provided that the following shall not be deemed

transactions described in this Prospectus under the caption "Certain
Transactions".
 
  Additional Subsidiary Guarantees
 
     The Indenture will provide that if the Company or any of its Subsidiaries
shall acquire or create another Subsidiary after the date of the Indenture, then
such newly acquired or created Subsidiary will be required to execute a
Guarantee and deliver an opinion of counsel, in accordance with the terms of the
Indenture.
 
  Business Activities
 
     The Company will not, and will not permit any Subsidiary to, engage in any
material respect in any business other than the Oil and Gas Business.
 
  Commission Reports
 
     Notwithstanding that the Company may not be required to remain subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the
extent permitted by the Exchange Act the Company will file with the Commission
and provide, within 15 days after such filing, the Trustee and Holders and
prospective Holders (upon request) with the annual reports and the information,
documents and other reports which are specified in Sections 13 and 15(d) of the
Exchange Act. In the event that the Company is not permitted to file such
reports, documents and information with the Commission, the Company will provide
substantially similar information to the Trustee, the Holders, and prospective
Holders (upon request) as if the Company were subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act. The Company also will
comply with the other provisions of Section 314(a) of the Trust Indenture Act.
 
EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture will provide that each of the following constitutes an Event
of Default: (i) a default for 30 days in the payment when due of interest on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (ii) a default in payment when due of the principal of or premium,
if any, on the Notes (whether or not prohibited by the subordination provisions
of the Indenture); (iii) the failure by the Company to comply with its
obligations under "Certain Covenants -- Merger, Consolidation or Sale of Assets"
above; (iv) the failure by the Company for 30 days after notice from the Trustee
or the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding to comply with the provisions described under the captions
"Repurchase at the Option of Holders and "Certain Covenants" other than the
provisions described under "-- Merger, Consolidation or Sale of Assets"; (v)
failure by the Company for 60 days after notice from the Trustee or the Holders
of at least 25% in aggregate principal amount of the Notes then outstanding to
comply with any of its other agreements in the Indenture or the Notes; (vi)
except as permitted by the Indenture, any Guarantee shall be held in any
judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect or a Subsidiary Guarantor, or any Person acting
on behalf of such Subsidiary Guarantor, shall deny or disaffirm its obligations
under its Guarantee; (vii) a default under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any of its Subsidiaries
(or the payment of which is guaranteed by the Company or any of its
Subsidiaries) whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, which default (a) is caused by a failure to pay
principal of
 
                                      A-17
<PAGE>   111
 
or premium, if any, or interest on such Indebtedness prior to the expiration of
the grace period provided in such Indebtedness on the date of such default (a
"Payment Default") or (b) results in the acceleration of such Indebtedness prior
to its express maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness
under which there is then existing a Payment Default or the maturity of which
has been so accelerated, aggregates $10.0 million or more; (viii) the failure by
the Company or any of its Subsidiaries to pay final, non-appealable judgments
aggregating in excess of $5.0 million, which judgments remain unpaid or
discharged for a period of 60 days; and (ix) certain events of bankruptcy or
insolvency with respect to the Company or any of its Subsidiaries.
 
     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Notes then outstanding may
declare the principal of and accrued but unpaid interest on such Notes to be due
and payable immediately. Notwithstanding the foregoing, in the case of an Event
of Default arising from certain events of bankruptcy or insolvency, with respect
to the Company or any Subsidiary, all outstanding Notes will become due and
payable without further action or notice. Holders of the Notes may not enforce
the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in principal amount of the Notes then
outstanding may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of the Notes notice of any continuing Default
or Event of Default (except a Default or Event of Default relating to the
payment of principal or interest) if it determines that withholding notice is in
their interest.
 
     The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest or premium on, or the principal of, the Notes.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required, within
five business days of becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance") except for (i) the rights of Holders of such outstanding Notes to
receive payments in respect of the principal of, premium, if any, interest on
such Notes when such payments are due from the trust referred to below, (ii) the
Company's obligations with respect to such Notes concerning issuing temporary
Notes, registration of such Notes, mutilated, destroyed, lost or stolen Notes
and the maintenance of an office or agency for payment and money for security
payments held in trust, (iii) the rights, powers, trusts, duties and immunities
of the Trustee, and the Company's obligations in connection therewith and (iv)
the Legal Defeasance provisions of the Indenture. In addition, the Company may,
at its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default. In the event
Covenant Defeasance occurs, certain events (not including non-payment,
bankruptcy, receivership, rehabilitation and insolvency events) described under
"Events of Default and Remedies" will no longer constitute an Event of Default.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest on the outstanding Notes
on the stated maturity or on the applicable redemption date, as the case may be,
and the Company must specify whether the Notes are being defeased to maturity or
to a particular redemption date; (ii) in the case of Legal Defeasance, the
Company shall have delivered to the Trustee an opinion of counsel in the United
States reasonably acceptable to such Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or
 
                                      A-18
<PAGE>   112
 
(B) since the date of the Indenture, there has been a change in the applicable
federal income tax law, in either case to the effect that, and based thereon
such opinion of counsel shall confirm that, the Holders of the outstanding Notes
will not recognize income, gain or loss for federal income tax purposes as a
result of such Legal Defeasance and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such Legal Defeasance had not occurred; (iii) in the case of Covenant
Defeasance, the Company shall have delivered to the Trustee an opinion of
counsel in the United States reasonably acceptable to such Trustee confirming
that the Holders of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Covenant Defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Covenant Defeasance
had not occurred; (iv) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or insofar
as Events of Default from bankruptcy or insolvency events are concerned, at any
time in the period ending on the 91st day after the date of deposit: (v) such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation
of, or constitute a default under any material agreement or instrument (other
than the Indenture) to which the Company or any of its Subsidiaries is a party
or by which the Company or any of its Subsidiaries is bound; (vi) the Company
must have delivered to the Trustee an opinion of counsel to the effect that
after the 91st day following the deposit, the trust funds will not be subject to
the effect of any applicable bankruptcy, insolvency, reorganization or similar
laws affecting creditors' rights generally; (vii) the Company must deliver to
the Trustee an Officers' Certificate stating that the deposit was not made by
the Company with the intent of preferring the Holders of the Notes over the
other creditors of the Company, or with the intent of defeating, hindering,
delaying or defrauding creditors of the Company or others; and (viii) the
Company must deliver to the Trustee an Officers' Certificate and an opinion of
counsel, each stating that all conditions precedent provided for relating to the
Legal Defeasance or the Covenant Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company is not required to transfer or exchange any Note selected
for redemption. Also, the Company is not required to transfer or exchange any
Note for a period of 15 days before a selection of the Notes to be redeemed.
 
     The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next two succeeding paragraphs, the Indenture or
the Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, the Notes), and any existing default or
compliance with any provision of such Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for the Notes).
 
     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of the Notes whose Holders must consent to an amendment,
supplement or waiver, (ii) reduce the principal of or change the fixed maturity
of any Note, (iii) reduce the rate of or change the time for payment of interest
on any Note, (iv) waive a Default or Event of Default in the payment of
principal of or premium, if any, or interest on the Notes (except a recision of
acceleration of the Notes by the Holders of at least a majority in principal
amount of such Notes and a waiver of the payment default that resulted from such
acceleration), (v) make any Note payable in money other than that stated in the
Notes, (vi) make any change in the provisions of the Indenture relating to
waivers of past Defaults or the rights of Holders of the Notes to receive
payments of principal of or premium,
 
                                      A-19
<PAGE>   113
 
if any, or interest on the Notes or (vii) make any change in the foregoing
amendment and waiver provisions. In addition, any amendment to the provisions of
Article [ ] of the Indenture (which relate to subordination) will require the
consent of the Holders of at least 66 2/3% in principal amount of the Notes then
outstanding if such amendment would adversely affect the rights of Holders of
such Notes. However, no amendment may be made to the subordination provisions of
the Indenture that adversely affects the rights of any holder of Senior Debt
then outstanding unless the holders of such Senior Indebtedness (or any group or
representative thereof authorized to give a consent) consents to such change.
 
     Notwithstanding the foregoing, without the consent of any Holder of the
Notes the Company and the Trustee may amend or supplement the Indenture or the
Notes to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in the case of a merger or consolidation, to make any change that would provide
any additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest, it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue or resign.
 
     The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his own affairs. Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any Holder of the Notes, unless such Holder shall have offered to
such Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

liabilities including liabilities under the Securities Act, and to contribute to

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the DGCL authorizes, inter alia, a corporation to indemnify
any person ("indemnitee") 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 (other than an action
by or in the right of the corporation), by reason of the fact that such person
is or was an officer or director of such corporation, or is or was serving at
the request of such corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that he acted in good
faith and in a manner he reasonably believes 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. A
Delaware corporation may indemnify past or present officers and directors of
such corporation or of another corporation or other enterprise at the former
corporation's request, in an action by or in the right of the corporation to
procure a judgment in its favor under the same conditions, except that no
indemnification is permitted without judicial approval if such person is
adjudged to be liable to the corporation. Where an officer or director is
successful on the merits or otherwise in defense of any action referred to
above, or in defense of any claim, issue or matter therein, the corporation must
indemnify him against the expenses (including attorneys' fees) which he actually
and reasonably incurred in connection therewith. Section 145 further provides
that any indemnification shall be made by the corporation only as authorized in
each specific case upon a determination by the (i) stockholders, (ii) Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding or (iii) independent counsel if a
quorum of disinterested directors so directs. Section 145 provides that
indemnification pursuant to its provision is not exclusive of other rights of
indemnification to which a person may be entitled under any bylaw, agreement,
vote of stockholders or disinterested directors or otherwise.
 
     Section 145 of the DGCL also empowers the Company to purchase and maintain
insurance on behalf of any person who is or was an officer or director of the
Company against liability asserted against or incurred by him in any such
capacity, whether or not the Company would have the power to indemnify such
officer or director against such liability under the provisions of Section 145.

<PAGE>   126
 
     Article SEVENTH, section (5) of the Company's Certificate of Incorporation
provides:
 
          Any former, present or future director, officer or employee of the
     Company or the legal representative of any such director, officer or
     employee shall be indemnified by the Company
 
             (a) against reasonable costs, disbursements and counsel fees paid
        or incurred where such person has been successful on the merits or
        otherwise in any pending, threatened or completed civil, criminal,
        administrative or arbitrative action, suit or proceeding, and any appeal
        therein and any inquiry or investigation which could lead to such
        action, suit or proceeding, or in defense of any claim, issue or matter
        therein, by reason of such person being or having been such director,
        officer or employee, and
 
             (b) with respect to any such action, suit, proceeding, inquiry or
        investigation for which indemnification is not made under (a) above,
        against reasonable costs, disbursements (which shall include amounts
        paid in satisfaction of settlements, judgments, fines and penalties,
        exclusive, however, of any amount paid or payable to the Company) and
        counsel fees if such person also had no reasonable cause to believe the
        conduct was unlawful, with the determination as to whether the
        applicable standard of conduct was met to be made by a majority of the
        members of the Board of Directors (sitting as a committee of the Board)
        who were not parties to such inquiry, investigation, action, suit or
        proceeding or by any one or more disinterested counsel to whom the
        question may be referred to the Board of Directors; provided, however,
        in connection with any proceeding by or in the right of the Company, no
        indemnification shall be provided as to any person adjudged by any court
        to be liable for negligence or misconduct except as and to the extent
        determined by such court.
 
     Article EIGHTH of the Company's Certificate of Incorporation provides:
 
          No director of the Corporation shall be liable to the Corporation or
     its stockholders for monetary damages for breach of fiduciary duty as a
     director, except for liability (i) for any breach of the director's duty of
     loyalty to the Corporation or its stockholders, (ii) for acts or omissions
     not in good faith or which involve intentional misconduct or a knowing
     violation of law, (iii) under Section 174 of the Delaware General
     Corporation Law, or (iv) for any transaction from which the director
     derived an improper personal benefit. This paragraph shall not eliminate or
     limit the liability of a director for any act or omission occurring prior
     to the effective date of its adoption. If the General Corporation Law of
     the State of Delaware is hereafter amended to authorize corporate action
     further limiting or eliminating the personal liability of directors, then
     the liability of a director to the Corporation shall be limited or
     eliminated to the fullest extent permitted by the General Corporation Law
     of the State of Delaware, as so amended from time to time. No repeal or
     modification of this Article VIII, directly or by adoption of an
     inconsistent provision of this Certificate of Incorporation, by the
     stockholders of the Corporation shall be effective with respect to any
     cause of action, suit claim or other matter, but for this Article VIII,
     would accrue or arise prior to such repeal or modification.
 
     Article XII of the Company's Bylaws, incorporating the above provisions,
provides for an indemnification agreement to be entered into by directors' and
designated officers of the Company. All directors of the Company have executed
an indemnification agreement the form of which was approved by stockholders at
the Company's 1994 annual stockholders meeting.
 
     Article XII of the Company's Bylaws also allows the Company to purchase
liability insurance for officers and directors. As of the date hereof, there is
no such insurance in place.
 
     Article XIII of the Company's Bylaws, with certain specified exceptions,
limits the personal liability of the directors to Lomak or its stockholders for
monetary damages for breach of fiduciary duty to the fullest extent permitted by
Delaware law, including any changes in Delaware law adopted in the future.
 
     The form of the Underwriting Agreements filed as Exhibit 1.1 and 1.2 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 17. UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     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 foregoing provisions, 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 in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person 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 of 1933 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 of 1933,
    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 (4) or
    497(h) under the Securities Act of 1933 shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
(2) For purposes of determining any liability under the Securities Act of 1933,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

                           5.07 hereof), to the extent that such difference
                           exceeds one half of one percent (1/2%) of the
                           Purchase Price (without giving effect to this Section
                           2.02 (b)(3));

                                    (4) an amount equal to the value of that
                           portion of the Properties with respect to which (i)
                           Seller is obligated by virtue of any prepayment

                           produced a share of gas in excess of its ownership
                           percentage and Seller is obligated to reduce its
                           share of production under a gas balancing agreement
                           or similar arrangement to allow under-produced

Seller separately represents and warrants the following:

                  (a) Each Seller is a duly organized, validly existing limited
         partnership organized and in good standing under the laws of its state
         of formation and is qualified to do business in the State of Texas.

                  (b) Each Seller has all requisite power and authority,
         partnership, corporate and otherwise, to carry on its business as
         presently conducted, to enter into the Agreement, to sell and convey,
         free and clear of all adverse claims, the Properties on the terms
         described in the Agreement and to perform its other obligations under
         the Agreement.

                  (c) The execution and delivery of this Agreement has been, and
         the execution and delivery of all certificates, documents and
         instruments required to be executed and delivered by Seller at the
         Closing, and the consummation of the transactions contemplated hereby
         as of the Effective Time shall have been duly authorized by all
         necessary partnership and corporate action on the part of the Seller,
         and, assuming expiration or termination of the applicable waiting
         period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
         ("HSR Act"), no further authorization is required by any law, statute,
         regulation, court order or judgment applicable to Seller. This
         Agreement constitutes a legal, valid and binding obligation of Seller
         enforceable in accordance with its terms, subject however, to the
         effects of bankruptcy, insolvency, reorganization, moratorium and
         similar laws, as well as to principles of equity (regardless of whether
         such enforceability is considered in a proceeding in equity or at law).

                  (d) The execution and delivery of the Agreement and the
         consummation of the transactions contemplated hereby will not (i)
         violate, or be in conflict with, any provisions of Seller's agreement
         of limited partnership or other governing documents, (ii) constitute a
         material breach of, or any event of default under, any contract or
         agreement to which Seller is a party or by which it or its assets are

represents and warrants to


                                       7
<PAGE>   13
Seller that:

                  (a) Buyer is a duly organized, validly existing corporation
         organized and in good standing under the laws of the State of its
         incorporation and is qualified to do business in the State of Texas.

                  (b) Buyer has all requisite power and authority, corporate and
         otherwise, to carry on its business as presently conducted, to enter
         into the Agreement, and to perform its obligations under the Agreement.

                  (c) The execution and delivery of this Agreement has been, and

         corporate action on the part of the Buyer and, assuming expiration or
         termination of the applicable waiting period under the HSR Act, no
         further authorization is required by any law, statute, regulation,
         court order or judgment applicable to Buyer. This Agreement constitutes
         a legal, valid and binding obligation of Buyer enforceable in
         accordance with its terms, subject however, to the effects of
         bankruptcy, insolvency, reorganization, moratorium and similar laws, as
         well as to principles of equity (regardless of whether such
         enforceability is considered in a proceeding in equity or at law).

                  (d) The execution and delivery of the Agreement and the
         consummation of the transactions contemplated hereby will not (i)
         violate, or be in conflict with, any provisions of Buyer's articles of
         incorporation, bylaws or governing documents, (ii) constitute a
         material breach of, or any event of default under, any contract or
         agreement to which Buyer is a party or by which it or its assets are
         bound, or constitute the happening of an event or condition upon which
         any other party to such a contract or agreement may exercise any right
         or option which will materially adversely affect the ability of Buyer
         to perform its obligations hereunder, (iii) assuming expiration or
         termination of the applicable waiting period under the HSR Act, violate
         any judgment, decree, order, statute, rule or regulation applicable to
         Buyer, or (iv) result in any material liability to Seller under the
         terms of any contracts or agreements to which Buyer is a party.

                  (e) No suit, action or other proceeding is pending before any
         court or governmental agency as of the date of this Agreement to which
         Buyer is a party and which might materially hinder or impede the
         ability of Buyer to perform its obligations hereunder. Buyer shall
         promptly notify Seller of any such proceeding arising prior to the
         Closing with respect to which Buyer receives actual notice.

                  (f) Buyer has incurred no liability, contingent or otherwise,
         for brokers' or finders' fees relating to the transactions contemplated
         by this Agreement for which Seller shall have any responsibility
         whatsoever.

                  (g) Buyer is a knowledgeable purchaser, owner and operator of
         oil and gas properties, has the ability to evaluate (and in fact has
         evaluated) the Properties for purchase, and is acquiring the Properties
         for its own account and not with the intent to make a distribution
         thereof within the meaning of the Securities Act of 1933 (and the rules
         and regulations pertaining thereto) or a distribution thereof in
         violation of any other applicable securities laws.

                  (h) In entering into this Agreement, Buyer has relied solely
         on the express representations and covenants of Sellers in this
         Agreement, its independent investigation of, and judgment with respect
         to, the Properties and the advice of its own legal, tax, economic,
         environmental, engineering, geological and geophysical advisors and not
         on any comments or statements of Seller or any representatives of, or
         consultants or advisors engaged by Seller.

                  (i) The Buyer's Stock to be issued by Buyer to Seller at
         Closing have been duly authorized for such issuance and, when issued
         and delivered by Buyer in accordance with the provisions of this
         Agreement, will be validly issued, fully paid, and nonassessable. Once
         registered in accordance with the provisions of Section 8.10 hereof,
         the Buyer's Stock shall be freely tradable by Seller or its assignees
         according to Section 8.10 hereof. The issuance of the Buyer's Stock
         under this Agreement is not subject to any preemptive or similar
         rights.

                  (j) Buyer is current in its obligations to file all periodic
         report and proxy statements with the Securities and Exchange Commission
         required to be filed under the Securities Exchange Act of 1934, as
         amended, and applicable rules and regulations promulgated thereunder.
         Buyer's Annual Report on Form-10K for the year ended December 31, 1995
         (the "SEC Document") does not contain an 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. Since December
         31, 1995, there have been no material developments, transactions or
         events affecting Buyer (other than developments or events affecting the
         oil and gas exploration and production industry generally) other than
         as disclosed by Buyer in the SEC Document or to Seller in writing.
         There are no material liabilities of Buyer (contingent or otherwise),
         other than as disclosed in the SEC Document and the financial
         statements included therein.

                  (k) The authorized and outstanding capital stock of Buyer as
         of September 30, 1996, consists solely of (a) 35,000,000 shares of
         Buyer's common stock, of which 14,705,293 shares are duly authorized,
         validly issued and outstanding, fully paid and non-assessable, and (b)
         4,000,000 shares of preferred stock, par value $1.00 per share, of
         which 1,150,000 shares are outstanding and are convertible into
         3,026,316 shares of Buyer's common stock.

                                    COVENANTS

         4.01 - COVENANTS OF SELLER.        Seller covenants and agrees
with Buyer that:

                  (a) Prior to the Closing, Seller will make available to Buyer
         for examination at Seller's office in Fort Worth, Texas, all title and
         other information relating to the Properties insofar as the same are in
         Seller's possession and will cooperate with Buyer in Buyer's efforts to
         obtain, at Buyer's expense, such additional information relating to the
         Properties as Buyer may reasonably desire, to the extent in each case
         that Seller may do so without violating legal constraints or any
         obligation of confidence or other contractual commitment of Seller to a
         third party. Historical file information in Seller's possession
         regarding crude oil and produced water which may have been spilled or
         disposed of on-site and the locations thereof; pits and pit closures;
         burials; landfarming; landspreading; underground injection; and solid
         waste disposal sites will be made available to Buyer for inspection
         prior to Closing. Seller shall permit representatives of Buyer to make
         such environmental tests as they deem appropriate, including without
         limitation Phase I and Phase II testing. Seller shall permit Buyer, at
         Buyer's expense, to inspect and photocopy such information and records
         at any reasonable time during the term of this Agreement but only to
         the extent, in each case, that Seller may do so without violating any
         obligation of confidence or contractual commitment to a third party.
         Seller shall not be obligated to furnish any updated abstracts, title
         opinions or additional title information, but shall cooperate with
         Buyer in Buyer's efforts to obtain, at Buyer's expense, such additional
         title information as Buyer may reasonably deem prudent.

                  (b) From the date of this Agreement Seller shall furnish to
         Buyer and shall cause its independent auditors to furnish to Buyer all
         information regarding the Properties, Seller and its respective
         business, assets, properties, and financial condition which, in the
         reasonable judgment of Buyer and/or its legal counsel and independent
         auditors is necessary to enable Buyer to comply with filing
         requirements under the Securities Act of 1933 (the "Act") and the
         Securities and Exchange Act of 1934 ("Exchange Act") to the extent
         deemed necessary by the Buyer and its representatives.

                  (c) From the date of this Agreement until Closing, Seller (i)
         will cause the Properties to be operated and maintained in a good and
         workmanlike manner consistent with prior practices, and will pay or
         cause to be paid all costs and expenses in connection therewith, (ii)
         will not abandon any Properties, (iii) will maintain insurance now in
         force with respect to the Properties, (iv) will comply with all the
         rules, regulations and orders of the Texas Railroad Commission which
         are applicable to Seller and the Properties, and will timely, properly
         and accurately make all reports required to be filed with the Texas
         Railroad Commission, (v) will perform and comply with all of the
         material covenants and conditions contained in the agreements relating
         to the Properties, and (vi) will pay all taxes and assessments with
         respect to the Properties which become due and payable prior to the
         Closing Date; provided however, in the absence of Buyer's written
         consent, from the date of this Agreement until the Closing, Seller
         shall not conduct or authorize any operation on


                                       10
<PAGE>   16
         the Properties requiring Authority for Expenditure (AFE) approval by
         working interest owners under applicable operating agreements, or an
         expenditure of $100,000.00 or more for the entire 100% of any single
         project (except for emergency operations and except for any AFEs
         identified on Exhibit "H" hereto). With respect to the Properties that
         are operated by Seller, as reimbursement for Seller's operating and
         managing the Properties for the period from the Effective Time to the
         Closing Date, Seller shall retain for its own account the amounts that
         are paid to Seller from third party non-operators as overhead charges
         under the accounting procedure attached to the applicable operating
         agreements with respect to the period after the Effective Time.

                  (d) Without the prior written consent of Buyer, from the date
         of this Agreement until Closing, Seller shall not enter into any new
         agreements or commitments with respect to the Properties, will not
         modify or terminate any of the agreements relating to the Properties,
         shall not encumber, sell, transfer, assign, convey, or otherwise
         dispose of any of the Properties other than personal property which is
         replaced by equivalent property or consumed in the operation of the
         Properties, and will not voluntarily compromise any amounts payable to
         Seller due to any casualty loss or any pending or threatened taking
         related to the Properties.

                  (e) Seller shall use all reasonable efforts to maintain its
         partnership status and to assure that as of the Closing it shall not be
         under any material partnership, legal or contractual restriction that
         would prohibit or delay the timely consummation of this transaction.
         With respect to any third-party consents and notices required under
         preferential rights to purchase provisions, Seller shall make requests
         of such third parties in compliance with applicable agreements, that
         such consents be given or waived and that such preferential rights be
         waived; provided however, nothing contained in this subsection of
         Section 4.01 shall require Seller to pay money or undertake any
         additional legal obligation.

                  (f) From the date of this Agreement until Closing, Seller
         shall permit Buyer's authorized representatives to consult with Seller
         and/or such third-party operator's agents and employees during
         reasonable business hours concerning the operations on or respecting
         the Properties that occur after the Effective Time and to conduct, at
         Buyer's sole risk and expense, on-site inspections (including, without
         limitation, site visits to offshore facilities of Seller),
         environmental assessments, reasonable tests and inventories of the
         Properties as provided in Section 5.03 hereof.

                  (g) As promptly as practicable and in any event not more than
         ten (10) days following the date on which the parties hereto shall have
         executed and delivered this Agreement, Seller will file with the
         Federal Trade Commission and the Department of Justice the notification
         and report form required for the transactions contemplated hereby and
         will as promptly as practicable furnish any supplemental information
         which may be reasonably requested in connection therewith pursuant to
         the HSR Act. Seller shall bear one-half (1/2) of the filing fees
         associated with filings made under the HSR Act and paid

         by Buyer or Seller.


                  (h) During the period from the date of this Agreement to the
         Closing Date, Seller shall use its best efforts to maintain its
         relationships with all suppliers, customers and others having business
         relationships with Seller with respect to the Properties so that such
         relationships will be preserved for Buyer on and after the Closing
         Date.

                  (i) Seller shall give Buyer notice of any litigation initiated

         fees associated with filings made under the HSR Act and paid by Buyer
         or Seller.


                  (c) Buyer shall exercise all due diligence in safeguarding and
         maintaining secure all engineering, geological and geophysical data,

         encumbrances, encroachment, irregularity, defect in or objection to
         Seller's title to the Properties (expressly excluding Permitted
         Encumbrances), that alone or in combination with other defects renders
         Seller's title to the Properties less than Defensible Title.

         (a)      As used herein the term "Defective Interest" shall
         mean

                           (4) That portion of the Properties with respect to
                  which any preferential right to purchase is exercised unless

         with the terms of Section 4.01(e) hereof ("Permitted Activities"),
         subject however, to the following conditions:

                  (a) Buyer shall notify Seller of its desire to enter the
         Properties to conduct Permitted Activities at least 48 hours prior to
         such entry.

                  (b) Upon receipt of such notice, Seller shall allow Buyer and
         its Representatives to enter the Properties during normal business
         hours to conduct Permitted Activities. The Permitted Activities of
         Buyer and its Representatives shall not unreasonably interfere with
         Seller's operations or business, and Buyer and its Representatives

         their Permitted Activities.

                  (c) The Permitted Activities shall be conducted in accordance

         have any right to control and shall not exercise any responsibility
         with respect to the Permitted Activities conducted by Buyer on the
         Properties, except that Seller shall have the right (but not the
         obligation) to prevent any damage to its property or disruption to its
         business. Buyer and its Representatives will undertake all measures
         reasonably necessary to protect all persons conducting the Permitted
         Activities on the Properties and any other persons who may enter the
         Properties during or after completion of the Permitted Activities.

         federal, state, or local agency with respect to environmental
         conditions discovered on the Properties without the prior written

         by applicable law, rule or regulation. Any proposal of Buyer or its
         Representatives to contact any federal, state, or local agency shall be
         delivered in writing to Seller for review and approval.

         AGENTS AND CONTRACTORS HARMLESS FROM AND AGAINST ANY ALL CLAIMS,
         LIABILITIES, CAUSES OF ACTIONS, JUDGMENTS OR DEFENSE EXPENSES
         (INCLUDING REASONABLE ATTORNEYS FEES AND EXPERT EXPENSES) OF ANY 
         PERSON, INCLUDING BUYER, ITS AFFILIATES AND THEIR RESPECTIVE OFFICERS,
         DIRECTORS, EMPLOYEES, AGENTS AND CONTRACTORS, FOR (I) PERSONAL INJURY
         OR DEATH OF ANY PERSON, (II) DAMAGE TO THE PROPERTY OF SELLER, BUYER OR
         ANY OTHER PERSON, OR (III) ALL OTHER DAMAGES OR ECONOMIC LOSSES
         (INCLUDING ANY DAMAGES CAUSED BY THE NEGLIGENCE OF SELLER),
         ATTRIBUTABLE TO OR ARISING FROM THE PERMITTED ACTIVITIES, EXCEPT THERE
         SHALL BE NO LIABILITY OF BUYER TO THE EXTENT ANY SUCH INJURY, DAMAGE,
         OR LOSS IS CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
         SELLER.

         5.04 - NOTICE OF DEFECTIVE INTERESTS.

                  (a) Buyer shall give Seller notice of Defective Interests not
         later than twenty-one (21) days from the date of this Agreement. Such
         notice shall be in writing and shall include (i) a description of the
         Defective Interest (ii) the reason Buyer believes such Properties to be
         a Defective Interest, and (iii) the Defect Value asserted by Buyer with
         respect to the asserted Defective Interest. Buyer's notice(s) of
         Defective Interests shall not be effective unless and until the total
         of the asserted Defect Values for the asserted Defective Interests
         exceeds one-half of one percent (1/2%) of the Purchase Price. Buyer
         shall be deemed to have waived all Defective Interests of which Seller
         has not been given such notice within the time period prescribed in
         this Section 5.04(a).

                  (b) Upon being notified by Buyer pursuant to Section 5.04(a)
         of any asserted Defective Interest the Seller shall give written
         counter-notice to Buyer within five (5) days (i) that it either (A)
         will attempt to correct the asserted Defective Interest, or (B) does
         not intend to attempt to correct the Defective Interest; and (ii)
         whether it agrees or disagrees that the asserted Defective Interest
         exist, and (iii) whether it agrees or disagrees with the Defect Value
         asserted by the Buyer.

                  (c) If Seller gives counter-notice of intent to attempt to
         correct any asserted


                                       17
<PAGE>   23
         Defective Interest, it shall have a period of thirty (30) days from the
         receipt of the Buyer's notice (the "Cure Period") to attempt to correct
         such asserted Defective Interest at its own expense. The Closing shall
         not be extended, but to the extent that the Defect Value allocated to
         the Defective Interest when combined with the Defect Value of all other
         asserted Defective Interests exceeds one-half of one percent (1/2%) of
         the Purchase Price, a downward adjustment of the Purchase Price shall
         be made in such amount according to Section 2.02(b)(5). If Seller shall
         subsequently cure such Defective Interest within the Cure Period, such
         Defect Value as to which curative has been effected shall be a credit
         to Seller in the determination of the Final Settlement according to
         Section 8.01 hereof. If Seller is unable to cure such Defective
         Interest, Seller shall still have the right to assert the provisions of
         Sections 5.04 (d) and (e) below after Closing, in which case Buyer
         shall deposit the amount of the disputed Defect Value with the Escrow
         Agent according to Section 5.06 (b) below.

                  (d) If Seller gives counter-notice (or notice after the Cure
         Period according to Section 5.04 (c)) that it disagrees there is a
         Defective Interest, then the existence (and if it exists, the Defect
         Value), will be determined by arbitration pursuant to Section 5.05
         hereof.

                  (e) If Seller gives counter-notice (or notice after the Cure
         Period according to Section 5.04 (c)) that it disagrees with the Defect
         Value asserted by Buyer in connection with a Defective Interest, then
         the amount of the Defect Value will be determined by arbitration
         pursuant to Section 5.05 hereof.

                  (f) The failure of Seller to deliver written counter-notice
         shall be deemed to be notice that Seller (i) will not attempt to
         correct that asserted Defective Interest, (ii) agrees that there is a
         Defective Interest and (iii) agrees with the Defect Value asserted by
         the Buyer.

                  (g) In determining which portions of the Properties are
         Defective Interests, it is the intent of the parties to include, when
         possible, only that portion of the Properties affected by the defect.


         5.05 - ARBITRATION PROCEDURES. If any matter is required by this
Article to be arbitrated, such arbitration shall be conducted as set forth in
this Section 5.05.

                  (a) The parties shall jointly select an acceptable person to
         serve as the sole arbitrator under this Agreement. If the parties are
         unable to agree upon the designation of a person as arbitrator under
         this Section 5.05, then either Seller or Buyer, or both such parties,
         may in writing request the American Arbitration Association to appoint
         a qualified arbitrator.

                  (b) Any arbitration hearing shall be held at a place in Fort
         Worth, Texas


                                       18
<PAGE>   24
         acceptable to the arbitrator.

                  (c) The arbitrator shall settle disputes regarding the
         existence of Defective Interests and/or the Defect Value thereof and
         Seller's attempts to correct any Title Defects in accordance with the
         Texas General Arbitration Act. Such arbitrator shall hear all
         arbitration matters arising under this Article V. The decision of the
         arbitrator shall be binding upon the parties, and may be enforced in
         any court of competent jurisdiction. Seller and Buyer, respectively,
         shall bear their own legal fees and other costs incurred in presenting
         their respective cases. The charges and expenses of the arbitrator
         shall be shared equally by Seller and Buyer.

                  (d) The arbitration shall commence within ten days after the
         arbitrator is selected as set forth in Section 5.05(a) above. In
         fulfilling his duties hereunder, the arbitrator shall be bound by the
         terms of this Agreement. In fulfilling any of his arbitration duties,
         the arbitrator may consider such other matters as in the opinion of the
         arbitrator are necessary or helpful to make a proper evaluation.
         Additionally, the arbitrator may consult with and engage disinterested
         third parties, including, without limitation, petroleum engineers,
         attorneys and consultants, to advise the arbitrator.

                  (e) If any arbitrator selected hereunder should die, resign or
         be unable to perform his duties hereunder, the parties, or if the
         parties are unable to agree, the American Arbitration Association shall
         select a replacement arbitrator. The aforesaid procedure shall be
         followed from time to time as necessary.

         5.06 - EFFECT OF DEFECTIVE INTERESTS ON THE CLOSING. If Buyer asserts
any Defective Interests the following shall apply:

                  (a) The parties shall proceed to the Closing as provided in
         this Agreement if (i) Seller elects to cure the asserted defect
         according to Section 5.04(c), (ii) Buyer agrees to waive the relevant
         Defective Interest and purchase the Defective Interest notwithstanding
         the asserted Defective Interest, or (iii) Buyer and Seller agree to a
         Defect Value and the Purchase Price is reduced by such amount in
         accordance with Section 2.02(b) hereof.

                  (b) If any matter is referred to arbitration under Section
         5.05 of this Agreement and the Defect Value or Values asserted by Buyer
         with respect to the matters under arbitration when combined with all
         other Defective Interests totals less than ten percent (10%) of the
         Purchase Price (including an agreement by Buyer to waive any
         arbitration award which when combined with all other Defective
         Interests would exceed ten percent (10%) of the Purchase Price), then
         the parties shall proceed to Closing, the asserted Defective Interests
         shall be conveyed to Buyer, and the Closing Amount (defined below)
         shall be reduced by an amount equal to the asserted Defect Values of
         the asserted Defective Interests (the "Withheld Payment"). The Withheld
         Payment shall be placed in escrow with the same entity under
         essentially the same terms as the Earnest Money (defined below). The
         Withheld Payment shall be paid as follows:

                                       19
<PAGE>   25
                  (i) If the arbitrator decides that any Defective Interest
                  asserted by the Buyer is not a Defective Interest, then the
                  Withheld Payment with respect to the asserted Defective
                  Interest shall be paid to the Seller.

                  (ii) If the arbitrator decides that any one or more of the
                  Defective Interests asserted by the Buyer are in fact
                  Defective Interests, then, the Withheld Payment, to the extent
                  it, when combined with all other Defective Interests, exceeds
                  one-half of one percent (1/2%) of the Purchase Price up to the
                  amount of the Defect Value, as determined by the arbitrator,
                  shall be distributed to the Buyer, and the remainder, if any,
                  shall be distributed to the Seller.

                  (c) If any matter is referred to arbitration under Section
         5.05 of this Agreement and the Defect Value asserted by Buyer with
         respect to the matters under arbitration when combined with all other
         Defective Interests totals ten percent (10%) of the Purchase Price or
         more, then, unless the parties otherwise agree, the Buyer waives its
         rights to an arbitration award, which, when combined with all other
         Defective Interests exceeds ten percent (10%) of the Purchase Price, or
         this Agreement is terminated by Seller pursuant to Article IX hereof.
         If none of the foregoing occurs, the Closing shall be postponed until
         the arbitrator renders his final decision . After the arbitrator
         renders his final decision the parties shall proceed to the Closing,
         and the Purchase Price will be reduced by the Defect Value found by the
         arbitrator to the extent it, when combined with all other Defective
         Interests, exceeds one-half of one percent (1/2%) of the Purchase
         Price; provided however, nothing contained in this Section 5.06(c)
         shall be deemed to in any way modify or terminate Seller's or Buyer's
         conditions to Closing under Section 6.01(d) or 6.02(d).

         5.07 - INCREASED INTERESTS OF SELLER.. If Seller owns a greater
undivided interest in the Properties than reflected in the Exhibits hereto which
results in an increase in value of a portion of the Properties, the party
discovering such inaccuracy shall immediately notify the other party and Buyer
and Seller shall endeavor to agree upon an amount that will be set-off against
the Defect Value of the Defective Interests in accordance with Section
2.02(b)(3) (the "Upward Adjustment"). If Buyer and Seller fail to agree to the
Upward Adjustment, Seller may elect to have that portion of the Properties
subject to such increase in value excluded from the Properties to be purchased
by Buyer.

                            OBLIGATIONS AFTER CLOSING

         8.01 - POST-CLOSING ADJUSTMENTS.

                                       24
<PAGE>   30
                  (a) As soon as practicable after the Closing, but not later
         than 60 days after the Closing, Seller shall prepare and deliver to
         Buyer, in accordance with this Agreement and generally accepted
         accounting principles, a statement ("Seller's Final Settlement
         Statement") setting forth each adjustment to Purchase Price that was
         not finally determined as of the Closing and showing the calculation of
         such adjustments. As soon as practicable after receipt of Seller's
         Final Settlement Statement, and no later than 90 days after the Closing
         Date, Buyer shall deliver to the Seller a written report containing any
         changes that Buyer proposes be made to Seller's Final Settlement
         Statement. The parties shall undertake to agree with respect to the
         amounts due pursuant to such Post-Closing adjustment not later than 135
         days after the Closing Date. If Buyer fails to propose any changes to
         the accounting set forth in the Seller's Final Settlement Statement, it
         shall be deemed that Buyer agrees with Seller's Final Settlement
         Statement. The final agreed price paid by Buyer to Seller for the
         Properties after all adjustments is hereinafter referred to as the
         "Final Purchase Price." The date upon which such agreement is reached
         or upon which the Final Purchase Price is established, shall be herein
         called the "Final Settlement Date".

                  (b) If Seller and Buyer are unable to agree upon the Final
         Sales Price within 135 days from the Closing Date, Price Waterhouse,
         independent public accountants, is designated to act as an arbitrator
         and to decide all points of disagreement with respect to the Final
         Sales Price, such decision to be binding upon both parties. If such
         firm is unwilling or unable to serve in such capacity, Seller and Buyer
         shall attempt to, in good faith, designate another acceptable person as
         the sole arbitrator under this Section . If the parties are unable to
         agree upon the designation of a person as substitute arbitrator, then
         Seller or Buyer, or both of them, may in writing request the American
         Arbitration Association to appoint the substitute arbitrator. The
         arbitration shall be conducted under the Texas General Arbitration Act
         and the rules of the American Arbitration Association to the extent
         such rules do not conflict with the terms of such Act and terms hereof.
         The costs and expenses of the arbitrator, whether the firm designated
         above, or a third party appointed pursuant to the preceding sentence
         shall be shared equally by Seller and Buyer. Within five (5) days after
         the decision of the arbitrator, the Buyer or Seller, as the case may
         be, shall promptly make a cash payment to the other equal to the sum as
         may be found to be due as the Final Sales Price. Notwithstanding the
         foregoing provisions of this Section 8.01(b), any questions with
         respect to a Defective Interest or Defect Value shall be resolved
         pursuant to the terms of Article V hereof.

         8.02 - SALES TAXES AND RECORDING FEES. Buyer shall pay all sales taxes
occasioned by the sale of the Properties and all documentary, filing and
recording fees required in connection with the filing and recording of any
assignments.

         8.03 - FURTHER ASSURANCES. After Closing, Seller and Buyer shall
execute, acknowledge and deliver or cause to be executed, acknowledged and
delivered such instruments and take such other action including payment of
monies as may be necessary or advisable to carry out their


                                       25
<PAGE>   31
obligations under this Agreement and under any document, certificate or other
instrument delivered pursuant hereto or required by law.

         8.04 - BUYER'S POST-CLOSING OBLIGATIONS.

                  (a) If at any time subsequent to the Closing, Buyer comes into
         possession of money or property belonging to the Seller that was not
         previously accounted for by credit or adjustment according to this
         Agreement such money or other property shall be promptly delivered to
         the Seller.

                  (b) Buyer assumes all liabilities attributable to the
         Properties arising from, attributable to, or alleged to be arising from
         or attributable to a violation of, or the failure to perform any
         obligation imposed by any and all laws, statutes, ordinances, rules,
         regulations, orders or determinations of any governmental authority
         pertaining to health or environment, including Environmental Laws, in
         effect where the Properties are located, regardless of when such
         violation or failure to perform occurred or is deemed to have occurred,
         EXCEPT THAT Buyer does not assume, and Seller shall retain any
         liability attributable to compliance with, violation of, or the failure
         to perform any obligation with respect to the Properties imposed by any
         Environmental Laws (as defined below) provided that such liability,
         when added to any liability of Rockland, L.P. under the Plant Agreement
         for the violation of, or the failure to perform any obligation imposed
         by any Environmental Law with respect to the assets covered by the
         Plant Agreement, shall not exceed $8,000,000 in the aggregate (the
         "Aggregate Liability Amount"), if and only if (i) such liability or
         obligation occurred prior to the Effective Time, and (ii) Buyer has
         provided written notice of such liability or obligation specifying the
         location and nature of the such liability within one (1) year from the
         Closing Date ("Environmental Liability"). Buyer does assume any
         liability attributable to compliance with, violation of, or the failure
         to perform any obligation with respect to the Properties imposed by,
         any Environmental Laws which occurred prior to the Effective Time and
         which is in excess of the Aggregate Liability Amount. In connection
         with this assumption of liability by Buyer, Buyer agrees that prior to
         Closing it will conduct such inspections of the properties as deemed
         necessary by it to fully evaluate the condition of the Properties. As
         used in this Agreement "Environmental Laws" means all laws, as they
         exist on the date hereof, relating to (a) the control of any pollutant
         or potential pollutant or protection of the air, water, land or the
         environment, (b) solid, gaseous or liquid waste generation, handling,
         treatment, storage, disposal or transportation, or (c) exposure to
         hazardous, toxic, explosive, corrosive or other substances alleged to
         be harmful. "Environmental Laws" shall include, but not be limited to,
         the Clean Air Act, 42 U.S.C. Section 7401 et seq., the Clean Water Act
         33 U.S.C. Section 1251 et seq., the Resource Conservation Recovery Act,
         42 U.S.C. Section 6901 et seq., the Superfund Amendments and
         Reauthorization Act, 42 U.S.C. Section 11001 et seq., the Water
         Pollution Control Act, 33 U.S.C. Section 1251 et seq., the Safe 
         Drinking Water Act, 42 U.S.C. Section 300f et seq., and the 
         Comprehensive Environmental Response, Compensation and Liability Act, 
         42 U.S.C. Section 9601 et seq.

                                       26
<PAGE>   32
                  (c) Except with respect to Environmental Liabilities as
         defined in Section 8.04(b), Buyer assumes all duties and obligations of
         the owner of the Properties which accrue or arise from and after the
         Effective Time. Without limitation of the foregoing, Buyer assumes (i)
         all obligations of Seller under the Contracts arising after the
         Effective Time, (ii) all accounts payable and contractual obligations
         incurred by Seller in accordance with this Agreement with respect to
         the Properties attributable to periods on or after the Effective Time,
         (iii) the obligation to make proper distribution of any suspense
         accounts transferred to Buyer in accordance with standard industry
         practice, regardless of whether the suspense funds accrued prior or
         subsequent to the Effective Time, (iv) all obligations to properly
         remove all pipe and equipment, close pits and to cleanup and restore
         any property included in or affected by the Properties, and (v) all
         liabilities and obligations resulting from injury or death to persons
         and damage to property which occur after the Closing Date.

                  (d) If, pursuant to Section 4.01(d), Seller does not provide
         notice to any third parties under preferential rights to purchase
         provisions requesting waiver of such provisions, or if such request for
         waiver is made by Seller prior to Closing, but the third party's waiver
         of or election to exercise the preferential right is not due under the
         applicable agreement until after Closing, the affected Property shall
         be conveyed to and purchased by Buyer at Closing pursuant to the terms
         of this Agreement subject to the terms of the applicable preferential
         right to purchase. After Closing, Buyer shall, if necessary, provide
         notice to the appropriate third parties requesting waiver of the
         applicable preferential rights to purchase and/or comply with the terms
         of the preferential rights to purchase that are properly exercised
         after Closing, with Buyer receiving all consideration payable upon the
         exercise of such preferential rights to purchase.

                  (e) For a period of one (1) year after the Closing Date,
         Buyer, or its successor who expressly assumes its obligations and
         liabilities hereunder, shall maintain its corporate or other legal
         status and shall at all times own assets having a value net of
         liabilities of not less than $50,000,000.

                  (f) BUYER AGREES TO INDEMNIFY, RELEASE, DEFEND AND HOLD
         HARMLESS SELLER, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,

is not in a significantly disparate bargaining position with Seller. Buyer

assets and perform its obligations under this Agreement has been predicated upon
the inapplicability of the DTPA or any similar statute and this waiver of the
DTPA and any similar statute. Buyer further recognizes that Seller, in
determining to proceed with the entering into of this Agreement has expressly
relied on the provisions of this Section 8.08.

all amounts payable to third parties out of production attributable to the
Properties and held in suspense by Seller.

the statements therein not misleading, and, at the request of Seller, Buyer will
prepare a supplement or amendment to such prospectus so that, as thereafter

stock split or a combination of shares);

                           (ix) make available for inspection by Seller, any
underwriter participating in any disposition pursuant to the Registration
Statement and any attorney, accountant or other agent retained by Seller or
underwriter, all financial and other records (as may be reasonably requested),
pertinent corporate documents and properties of Buyer as shall be reasonably
necessary to enable them to exercise their due diligence responsibility, and
cause Buyer's officers, directors,, employees and independent accountants to
supply all information reasonably requested by Seller, underwriter, attorney,
accountant or agent in connection with the Registration Statement; provided,

information is made


                                       31
<PAGE>   37
generally available to the public and Seller shall cause any attorney,
accountant or agent retained by Seller to keep confidential any information so
deemed;

                           (x) otherwise use reasonable efforts to comply with

11(a) of the Securities Act and Rule 158 thereunder;

                           (ix) in the event of the issuance of any stop order
suspending the effectiveness of the Registration Statement, or of any order
suspending or preventing the use of any related prospectus or suspending the
qualification of any common stock included in the Registration Statement for
sale in any jurisdiction, Buyer will use reasonable efforts promptly to obtain
the withdrawal of such order;

                           (xii) use reasonable efforts to cause the Buyer's
Stock covered by the Registration Statement to be registered with or approved by
such other governmental agencies or authorities as may be necessary to enable
Seller to consummate the disposition of the Buyer's Stock;

period that is recommended in the written opinion of Buyer's managing
underwriter, provided that such period shall not exceed 45 days after the
effective date of the registration statement for the Public Offering.

                                 INDEMNIFICATION

         11.01 - RIGHT TO EMPLOY COUNSEL.

                  (a) When any claim, action, or suit shall be filed or asserted
         in writing against any party which is indemnifiable under the terms of
         this Agreement, the indemnified party shall promptly notify the
         indemnifying party of the same in writing, specifying in detail the


                                       35
<PAGE>   41
         basis of such claim and the facts pertaining thereto, and the
         indemnifying party shall, at its option, have the right to assume the
         defense thereof or participate in the defense thereof and to employ its
         own legal counsel in connection with such defense. Failure of the
         indemnified party to notify the indemnifying party of such claim,
         action, or suit within twenty (20) calendar days after notice to the
         indemnified party of such claim, action, or suit shall constitute a
         waiver of its rights under this Article, unless such failure to notify
         within such time period shall not prejudice the rights of the
         indemnifying party in respect of such claim, action or suit, in which
         case prompt notification as provided above shall be sufficient.

                  (b) The indemnified party shall have the right to employ
         counsel separate from counsel employed by the indemnifying party in any
         such action and to participate in the defense thereof, but the fees and
         expenses of such counsel employed by the indemnified party shall be at
         the sole expense of the indemnified party unless (i) the indemnifying
         party shall have elected not or shall have failed to assume or
         participate in the defense thereof, (ii) the employment thereof has
         been specifically authorized by the indemnifying party in writing, or
         (iii) the parties to any such action (including any impleaded parties)
         include both the indemnifying and indemnified party, and the
         indemnified party shall have been advised by its counsel that there may
         be one or more legal defenses available to it which are different from
         or additional to those available to the indemnifying party (in any
         which case (i), (ii) or (iii) above the indemnifying party shall not
         have the right to assume the defense of such action on behalf of the
         indemnified party and the fees and expenses of such counsel employed by
         the indemnified party shall be at the sole expense of the indemnifying
         party).


                  (c) Prior to effectuating any settlement of any such action or
         proceeding, the indemnified party shall furnish the indemnifying party
         with written notice of any proposed settlement in sufficient time to
         allow the indemnifying party to act thereon. The indemnifying party

                  (a) Seller is a duly organized, validly existing limited
         partnership organized and in good standing under the laws of its state
         of formation and is qualified to do business in the State of Texas.

                  (b) Seller has all requisite power and authority, partnership,
         corporate and otherwise, to carry on its business as presently
         conducted, to enter into the Agreement, to sell and convey, free and
         clear of all adverse claims, the Properties on the terms described in
         the Agreement and to perform its other obligations under the Agreement.

                  (c) The execution and delivery of this Agreement has been, and
         the execution and delivery of all certificates, documents and
         instruments required to be executed and delivered by Seller at the
         Closing, and the consummation of the transactions contemplated hereby
         as of the Effective Time shall have been duly authorized by all
         necessary partnership and corporate action on the part of the Seller,
         and, assuming expiration or termination of the applicable waiting
         period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
         ("HSR Act"), no further authorization is required by any law, statute,
         regulation, court order or judgment applicable to Seller. This
         Agreement constitutes a legal, valid and binding obligation of Seller
         enforceable in accordance with its terms, subject however, to the
         effects of bankruptcy, insolvency, reorganization, moratorium and
         similar laws, as well as to principles of equity (regardless of whether
         such enforceability is considered in a proceeding in equity or at law).

                  (d) The execution and delivery of the Agreement and the
         consummation of the transactions contemplated hereby will not (i)
         violate, or be in conflict with, any provisions of Seller's agreement
         of limited partnership or governing documents, (ii) constitute a


                                       4
<PAGE>   8
         material breach of, or any event of default under, any contract or
         agreement to which Seller is a party or by which it or its assets are
         bound, or constitute the happening of an event or condition upon which
         any other party to such a contract or agreement may exercise any right
         or option which will materially adversely affect any of the Properties
         (except any provision as to (A) required consents to transfer and
         related provisions, (B) maintenance of uniform interests provisions and
         (C) any other third-party approvals contemplated herein), (iii)
         assuming expiration or termination of the applicable waiting period
         under the HSR Act, violate any judgment, decree, order, statute, rule
         or regulation applicable to Seller, or (iv) result in any material
         liability to Buyer under the terms of any contracts or agreements,
         except those obligations related to the Properties after the Effective
         Time and assumed by Buyer pursuant to the terms of the Agreement.

                  (e) Except as shown on Exhibit "D" attached hereto and made a
         part hereof, no suit, action or other proceeding is pending before any
         court or governmental agency as of the date of this Agreement to which
         Seller is a party and which might result in substantial impairment or
         loss of Seller's title to any material part of the Properties or that
         might materially hinder or impede the operation of the Leases or the
         ability of Seller to perform its obligations hereunder.

                  (f) Seller holds such permits, governmental licenses,
         approvals, authorizations and exemptions, including environmental
         permits, that are necessary to carry on its business as presently
         conducted and all of same are transferable to Buyer. The Facilities, as
         currently operated by Seller, do not require certificate authority from
         the Federal Energy Regulatory Commission. Seller has complied with all
         of the laws, regulations and orders of the Texas Railroad Commission
         and the United States Department of Transportation affecting the
         Properties. While Seller has owned the Properties (the "Ownership
         Period"), all necessary reports required by any governmental agency
         with respect to the Properties have been timely, properly and
         accurately made.

                  (g) During the Ownership Period, all ad valorem, property,
         production, severance and similar taxes and assessments based on or
         measured by the ownership of property or the production of hydrocarbons
         or the receipt of proceeds therefrom on the Properties have been
         properly paid.

                  (h) Seller has incurred no liability, contingent or otherwise,
         for brokers' or finders' fees relating to the transactions contemplated
         by this Agreement for which Buyer shall have any responsibility
         whatsoever.

                  (i) The contracts described on Exhibit "C" hereto are the only
         material agreements which provide for the purchase, sale, gathering,
         delivery, compressing, transporting, processing, marketing or any other
         disposition of the gas through the Facilities, and the contracts
         described on Exhibit "C" hereto and the easements described on Exhibit
         "A" hereto are the only agreements relating to the Facilities which
         might require a consent to assign or contain a preferential right to
         purchase or similar provision.


                                       5
<PAGE>   9
                  (j) Seller is not a "foreign person" within the meaning of
         Section 1445 of the Internal Revenue Code of 1986, as amended.

                  (k) The Properties comprise all assets, equipment and
         agreements that are necessary to operate the Properties in the ordinary

         further authorization is required by any law, statute, regulation,

         a legal, valid and binding obligation of Buyer enforceable in
         accordance with its terms, subject however, to the effects of
         bankruptcy, insolvency, reorganization, moratorium and similar laws, as

         consummation of the transactions contemplated hereby will not (i)
         violate, or be in conflict with, any provisions of Buyer's articles of

         material breach of, or any event of default under, any contract or
         agreement to which Buyer is a party or by which it or its assets are

                                       6
<PAGE>   10
         exercise any right or option which will materially adversely affect the
         ability of Buyer to perform its obligations hereunder, (iii) assuming

         court or governmental agency as of the date of this Agreement to which
         Buyer is a party and which might materially hinder or impede the
         ability of Buyer to perform its obligations hereunder. Buyer shall
         promptly notify Seller of any such proceeding arising prior to the
         Closing with respect to which Buyer receives actual notice.

         for brokers' or finders' fees relating to the transactions contemplated
         by this Agreement for which Seller shall have any responsibility
         whatsoever.

                  (g) Buyer is a knowledgeable purchaser, owner and operator of
         oil and gas properties, has the ability to evaluate (and in fact has
         evaluated) the Properties for purchase, and is acquiring the Properties
         for its own account and not with the intent to make a distribution
         thereof within the meaning of the Securities Act of 1933 (and the rules
         and regulations pertaining thereto) or a distribution thereof in
         violation of any other applicable securities laws.

                  (h) In entering into this Agreement, Buyer has relied solely
         on the express representations and covenants of Sellers in this
         Agreement, its independent investigation of, and judgment with respect
         to, the Properties and the advice of its own legal, tax, economic,
         environmental, engineering, geological and geophysical advisors and not
         on any comments or statements of Seller or any representatives of, or
         consultants or advisors engaged by Seller.

         requirements under the Securities Act of 1933 (the "Act") and the
         Securities and Exchange Act of 1934 ("Exchange Act") to the extent
         deemed necessary by the Buyer and its representatives.

         modify or terminate any of the agreements relating to the Properties,

                                    which individually and in the aggregate do
                                    not operate to interfere materially with the
                                    operation, value or use of the Properties;
                                    and

                           (ix)     Those matters described on Exhibit "E"

                  (c) The term "Title Defect" as used herein shall mean any
         encumbrances, encroachment, irregularity, defect in or objection to
         Seller's title to the Properties (expressly excluding Permitted
         Encumbrances), that alone or in combination with other defects renders
         Seller's title to the Properties less than Defensible Title.

<PAGE>   17
                  (a) Buyer shall notify Seller of its desire to enter the
         Properties to conduct Permitted Activities at least 48 hours prior to
         such entry.

                  (b) Upon receipt of such notice, Seller shall allow Buyer and
         its Representatives to enter the Properties during normal business
         hours to conduct Permitted Activities. The Permitted Activities of
         Buyer and its Representatives shall not unreasonably interfere with
         Seller's operations or business, and Buyer and its Representatives
         shall not remain on the Properties subsequent to the completion of
         their Permitted Activities. As soon as reasonably possible, Buyer shall

         result of conducting Permitted Activities.

                  (c) The Permitted Activities shall be conducted in accordance

         Permitted Activities.

                  (d) Buyer will be responsible for the conduct and protection
         of all persons involved in the Permitted Activities. Seller shall not
         have any right to control and shall not exercise any responsibility
         with respect to the Permitted Activities conducted by Buyer on the
         Properties, except that Seller shall have the right (but not the
         obligation) to prevent any damage to its property or disruption to its
         business. Buyer and its Representatives will undertake all measures
         reasonably necessary to protect all persons conducting the Permitted

         AGENTS AND CONTRACTORS HARMLESS FROM AND AGAINST ANY ALL CLAIMS,
         LIABILITIES, CAUSES OF ACTIONS, JUDGMENTS OR DEFENSE EXPENSES
         (INCLUDING REASONABLE ATTORNEYS FEES AND EXPERT EXPENSES) OF ANY
         PERSON, INCLUDING BUYER, ITS AFFILIATES AND THEIR RESPECTIVE OFFICERS,
         DIRECTORS, EMPLOYEES, AGENTS AND CONTRACTORS, FOR


                                       14

         OF SELLER, BUYER OR ANY OTHER PERSON, OR (III) ALL OTHER DAMAGES OR
         ECONOMIC LOSSES (INCLUDING ANY DAMAGES CAUSED BY THE NEGLIGENCE OF
         SELLER), ATTRIBUTABLE TO OR ARISING FROM THE PERMITTED ACTIVITIES,
         EXCEPT THER SHALL BE NO LIABILITY OF BUYER TO THE EXTENT ANY SUCH
         INJURY, DAMAGE, OR LOSS IS CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
         MISCONDUCT OF SELLER.

         5.04 - NOTICE OF DEFECTIVE INTERESTS.

                  (a) Buyer shall give Seller notice of Defective Interests not
         later than twenty-one (21) days from the date of this Agreement. Such
         notice shall be in writing and shall include (i) a description of the
         Defective Interest (ii) the reason Buyer believes such Properties to be
         a Defective Interest, and (iii) the Defect Value asserted by Buyer with
         respect to the asserted Defective Interest. Buyer's notice(s) of
         Defective Interests shall not be effective unless and until the total
         of the asserted Defect Values for the asserted Defective Interests
         exceeds one-half of one percent (1/2%) of the Purchase Price. Buyer
         shall be deemed to have waived all Defective Interests of which Seller
         has not been given such notice within the time period prescribed in
         this Section 5.04(a).


                  (b) Upon being notified by Buyer pursuant to Section 5.04(a)
         of any asserted Defective Interest the Seller shall give written
         counter-notice to Buyer within five (5) days (i) that it either (A)
         will attempt to correct the asserted Defective Interest, or (B) does
         not intend to attempt to correct the Defective Interest; and (ii)
         whether it agrees or disagrees that the asserted Defective Interest
         exist, and (iii) whether it agrees or disagrees with the Defect Value
         asserted by the Buyer.

                  (c) If Seller gives counter-notice of intent to attempt to
         correct any asserted Defective Interest, it shall have a period of
         thirty (30) days from the receipt of the Buyer's notice (the "Cure
         Period") to attempt to correct such asserted Defective Interest at its
         own expense. The Closing shall not be extended, but to the extent that
         the Defect Value allocated to the Defective Interest when combined with
         the Defect Value of all other asserted Defective Interests exceeds
         one-half of one percent (1/2%) of the Purchase Price, a downward
         adjustment of the Purchase Price shall be made in such amount according
         to Section 2.02(b)(5). If Seller shall subsequently cure such Defective
         Interest within the Cure Period, such Defect Value as to which curative
         has been effected shall be a credit to Seller in the determination of
         the Final Settlement according to Section 8.01 hereof. If Seller is
         unable to cure such Defective Interest, Seller shall still have the
         right to assert the provisions of Sections 5.04 (d) and (e) below after
         Closing, in which case Buyer shall deposit the amount of the disputed
         Defect Value with the Escrow Agent according to Section 5.06(b) below.


                                       15
<PAGE>   19
                  (d) If Seller gives counter-notice (or notice after the Cure
         Period according to Section 5.04(c)) that it disagrees there is a
         Defective Interest, then the existence (and if it exists, the Defect
         Value), will be determined by arbitration pursuant to Section 5.05
         hereof.

                  (e) If Seller gives counter-notice (or notice after the Cure
         Period according to Section 5.04(c)) that it disagrees with the Defect
         Value asserted by Buyer in connection with a Defective Interest, then
         the amount of the Defect Value will be determined by arbitration
         pursuant to Section 5.05 hereof.

                  (f) The failure of Seller to deliver written counter-notice
          shall be deemed to be notice that Seller (i) will not attempt to
          correct that asserted Defective Interest, (ii) agrees
         that there is a Defective Interest and (iii) agrees with the Defect
         Value asserted by the Buyer.

                  (g) In determining which portions of the Properties are
         Defective Interests, it is the intent of the parties to include, when
         possible, only that portion of the Properties affected by the defect.

         5.05 - ARBITRATION PROCEDURES. If any matter is required by this
Article to be arbitrated, such arbitration shall be conducted as set forth in
this Section 5.05.

                  (a) The parties shall jointly select an acceptable person as
         the sole arbitrator under this Agreement. If the parties are unable to
         agree upon the designation of a person as arbitrator, then either
         Seller or Buyer, or both such parties, may in writing request the
         American Arbitration Association to appoint a qualified arbitrator.

                  (b) Any arbitration hearing shall be held at a place in Fort
         Worth, Texas acceptable to the arbitrator.

                  (c) The arbitrator shall settle disputes regarding the
         existence of Defective Interests and/or the Defect Value thereof and
         Seller's attempts to correct any Title Defects
         in accordance with the Texas General Arbitration Act. Such arbitrator
         shall hear all arbitration matters arising under this Article V. The
         decision of the arbitrator shall be binding upon the parties, and may
         be enforced in any court of competent jurisdiction.
         Seller and Buyer, respectively, shall bear their own legal fees and
         other costs incurred in presenting their respective cases. The charges
         and expenses of the arbitrator shall be shared equally by Seller and
         Buyer.

                  (d) The arbitration shall commence within ten days after the
         arbitrator is selected as set forth in Section 5.05(a) above. In
         fulfilling his duties hereunder, the arbitrator shall be bound by the
         terms of this Agreement. In fulfilling any of his arbitration duties,
         the arbitrator may consider such other matters as in the opinion of the
         arbitrator are necessary or helpful to make a proper evaluation.
         Additionally, the arbitrator may

                                       16
<PAGE>   20
         consult with and engage disinterested third parties, including, without
         limitation, petroleum engineers, attorneys and consultants, to advise
         the arbitrator.

                  (e) If any arbitrator selected hereunder should die, resign or
         be unable to perform his duties hereunder the parties or if the parties
         are unable to agree, the American Arbitration Association shall select
         a replacement arbitrator. The aforesaid procedure shall be followed
         from time to time as necessary.

         5.06 - EFFECT OF DEFECTIVE INTERESTS ON THE CLOSING. If Buyer asserts
any Defective Interests the following shall apply:

                  (a) The parties shall proceed to the Closing as provided in
         this Agreement if (i) Seller elects to cure the asserted defect
         according to Section 5.04(c), (ii) Buyer agrees to waive the relevant
         Defective Interest and purchase the Defective Interest notwithstanding
         the asserted Defective Interest, or (iii) Buyer and Seller agree to a
         Defect Value and the Purchase Price is reduced by such amount in
         accordance with Section 2.02(b) hereof.

                  (b) If any matter is referred to arbitration under Section
         5.05 of this Agreement and the Defect Value or Values asserted by Buyer
         with respect to the matters under arbitration when combined with all
         other Defective Interests totals less than ten percent (10%) of the
         Purchase Price (including an agreement by Buyer to waive any
         arbitration award which when combined with all other Defective
         Interests would exceed ten percent (10%) of the Purchase Price), then
         the parties shall proceed to Closing, the asserted Defective Interests
         shall be conveyed to Buyer, and the Closing Amount (defined below)
         shall be reduced by an amount equal to the asserted Defect Values of
         the asserted Defective Interests (the "Withheld Payment"). The Withheld
         Payment shall be placed in escrow with the same entity under
         essentially the same terms as the Earnest Money (defined below). The
         Withheld Payment shall be paid as follows:

                           (i) If the arbitrator decides that any Defective
                           Interest asserted by the Buyer is not a Defective
                           Interest, then the Withheld Payment with respect to
                           the asserted Defective Interest shall be paid to the
                           Seller.

                           (ii) If the arbitrator decides that any one or more
                           of the Defective Interests asserted by the Buyer are
                           in fact Defective Interests, then, the Withheld
                           Payment, to the extent it, when combined with all
                           other Defective Interests, exceeds one-half (1/2) of
                           one percent (1/2%) of the Purchase Price up to the
                           amount of the Defect Value, as determined by the
                           arbitrator, shall be distributed to the Buyer, and
                           the remainder, if any, shall be distributed to the
                           Seller.

                  (c) If any matter is referred to arbitration under Section
         5.05 of this Agreement and the Defect Value asserted by Buyer with
         respect to the matters under arbitration when combined with all other
         Defective Interests totals ten percent (10%) of the Purchase Price


                                       17
<PAGE>   21
         or more, then, unless the parties otherwise agree, the Buyer waives its
         rights to an arbitration award which, when combined with all other
         Defective Interests exceeds ten percent (10%) of the Purchase Price, or
         this Agreement is terminated by Seller pursuant to Article IX hereof.
         If none of the foregoing occurs, the Closing shall be postponed until
         the arbitrator renders his final decision. After the arbitrator renders
         his final decision the parties shall proceed to the Closing, and the
         Purchase Price will be reduced by the Defect Value found by the
         arbitrator to the extent it, when combined with all other Defective
         Interests, exceeds one-half of one percent (1/2%) of the Purchase
         Price; provided however, nothing contained in this Section 5.06(c)
         shall be deemed to in any way modify or terminate Seller's or Buyer's
         conditions to Closing under Section 6.01(d) or 6.02(d).

                                  ARTICLE VIII

                            OBLIGATIONS AFTER CLOSING

         8.01 - POST-CLOSING ADJUSTMENTS.

                  (a) As soon as practicable after the Closing, but not later
         than 60 days after the Closing, Seller shall prepare and deliver to
         Buyer, in accordance with this Agreement and generally accepted
         accounting principles, a statement ("Seller's Final Settlement
         Statement" ) setting forth each adjustment to Purchase Price that was
         not finally determined as of the Closing and showing the calculation of
         such adjustments. As soon as practicable after receipt of Seller's
         Final Settlement Statement, and no later than 90 days after the Closing
         Date, Buyer shall deliver to the Seller a written report containing any
         changes that Buyer proposes be made to Seller's Final Settlement
         Statement. The parties shall undertake to agree with respect to the
         amounts due pursuant to such Post-Closing adjustment not later than 135
         days after the Closing Date. If Buyer fails to propose any


                                       21
<PAGE>   25
         changes to the accounting set forth in the Seller's Final Settlement
         Statement, it shall be deemed that Buyer agrees with Seller's Final
         Settlement Statement. The final agreed price paid by Buyer to Seller
         for the Properties after all adjustments is hereinafter referred to as
         the "Final Purchase Price." The date upon which such agreement is
         reached or upon which the Final Purchase Price is established, shall be
         herein called the "Final Settlement Date".

                  (b) If Seller and Buyer are unable to agree upon the Final
         Sales Price within 135 days from the Closing Date, Price Waterhouse,
         independent public accountants, is designated to act as an arbitrator
         and to decide all points of disagreement with respect to the Final
         Sales Price, such decision to be binding upon both parties. If such
         firm is unwilling or unable to serve in such capacity, Seller and Buyer
         shall attempt to, in good faith, designate another acceptable person as
         the sole arbitrator under this Section . If the parties are unable to
         agree upon the designation of a person as substitute arbitrator, then
         Seller or Buyer, or both of them, may in writing request the American
         Arbitration Association to appoint the substitute arbitrator. The
         arbitration shall be conducted under the Texas General Arbitration Act
         and the rules of the American Arbitration Association to the extent
         such rules do not conflict with the terms of such Act and terms hereof.
         The costs and expenses of the arbitrator, whether the firm designated
         above, or a third party appointed pursuant to the preceding sentence
         shall be shared equally by Seller and Buyer. Within five (5) days after
         the decision of the arbitrator, the Buyer or Seller, as the case may
         be, shall promptly make a cash payment to the other equal to the sum as
         may be found to be due as the Final Sales Price. Notwithstanding the
         foregoing provisions of this Section 8.01(b), any questions with
         respect to a Defective Interest or Defect Value shall be resolved
         pursuant to the terms of Article V hereof.

         8.02 - SALES TAXES AND RECORDING FEES. Buyer shall pay all sales taxes
occasioned by the sale of the Properties and all documentary, filing and
recording fees required in connection with the filing and recording of any
assignments.

         8.03 - FURTHER ASSURANCES. After Closing, Seller and Buyer shall
execute, acknowledge and deliver or cause to be executed, acknowledged and
delivered such instruments and take such other action including payment of
monies as may be necessary or advisable to carry out their obligations under
this Agreement and under any document, certificate or other instrument delivered
pursuant hereto or required by law.

         8.04 - BUYER'S POST-CLOSING OBLIGATIONS.

                  (a) If at any time subsequent to the Closing, Buyer comes into
         possession of money or property belonging to the Seller that was not
         previously accounted for by credit or adjustment according to this
         Agreement such money or other property shall be promptly delivered to
         the Seller.

                  (b) Buyer assumes all liabilities attributable to the
         Properties arising from,


                                       22
<PAGE>   26
         attributable to, or alleged to be arising from or attributable to a
         violation of, or the failure to perform any obligation imposed by any
         and all laws, statutes, ordinances, rules, regulations, orders or
         determinations of any governmental authority pertaining to health or
         environment in effect where the Properties are located, regardless of
         when such violation or failure to perform occurred or is deemed to have
         occurred, EXCEPT THAT Buyer does not assume, and Seller shall retain
         any liability attributable to compliance with, violation of, or the
         failure to perform any obligation with respect to the Properties
         imposed by any Environmental Laws (as defined below) provided that such
         liability, when added to any liability of Cometra Energy, L.P. and
         Cometra Production Company, L.P. under the Producing Properties
         Agreement for the violation of, or the failure to perform any
         obligation imposed by any Environmental Law with respect to the assets
         covered by the Producing Properties Agreement, shall not exceed
         $8,000,000 in the aggregate (the "Aggregate Liability Amount"), if and
         only if (i) such liability or obligation occurred prior to the
         Effective Time, and (ii) Buyer has provided written notice of such
         liability or obligation specifying the location and nature of the such
         liability within 180 days from the Closing Date ("Environmental
         Liability"). Buyer does assume any liability attributable to compliance
         with, violation of, or the failure to perform any obligation with
         respect to the Properties imposed by, any Environmental Laws which
         occurred prior to the Effective Time and which is in excess of the
         Aggregate Liability Amount. In connection with this assumption of
         liability by Buyer, Buyer agrees that prior to Closing it will conduct
         such inspections of the properties as deemed necessary by it to fully
         evaluate the condition of the Properties. As used in this Agreement
         "Environmental Laws" means all laws, as they exist on the date hereof,
         relating to (a) the control of any pollutant or potential pollutant or
         protection of the air, water, land or the environment, (b) solid,
         gaseous or liquid waste generation, handling, treatment, storage,
         disposal or transportation, or (c) exposure to hazardous, toxic,
         explosive, corrosive or other substances alleged to be harmful.
         "Environmental Laws" shall include, but not be limited to, the Clean
         Air Act, 42 U.S.C. Section 7401 et seq., the Clean Water Act 33 U.S.C.
         Section 1251 et seq., the Resource Conservation Recovery Act, 42 U.S.C.
         Section 6901 et seq., the Superfund Amendments and Reauthorization Act,
         42 U.S.C. Section 11001 et seq., the Water Pollution Control Act, 33
         U.S.C. Section 1251 et seq., the Safe Drinking Water Act, 42 U.S.C.
         Section 300f et seq., and the Comprehensive Environmental Response,
         Compensation and Liability Act, 42 U.S.C. Section 9601 et seq.

                  (c) Except with respect to Environmental Liabilities defined
         in Section 8.04(b). Buyer assumes all duties and obligations of the
         owner of the Properties which accrue or arise from and after the
         Effective Time. Without limitation of the foregoing, Buyer assumes (i)
         all obligations of Seller under the Easements, System Contracts and
         Permits arising after the Effective Time, (ii) all accounts payable and
         contractual obligations incurred by Seller in accordance with this
         Agreement with respect to the Properties attributable to periods on or
         after the Effective Time, (iii) the obligation to make proper
         distribution of any suspense accounts transferred to Buyer in
         accordance with standard industry practice, regardless of whether the
         suspence funds accrued prior or subsequent to the Effective Time, (iv)
         all obligations to properly remove all pipe and equipment now located
         on the land subject to the Easements or hereafter placed on the
         Easements by


                                       23
<PAGE>   27
         Buyer, its successors and assigns, and cleanup and restore any property
         included in or affected by the Properties, and (v) all liabilities and
         obligations resulting from injury or death to persons and damage to
         property which occur after the Closing Date.

                  (d) If, pursuant to Section 4.01(d), Seller does not provide
         notice to any third parties under preferential rights to purchase
         provisions requesting waiver of such provisions, or if such request for
         waiver is made by Seller prior to Closing, but the third party's waiver
         of or election to exercise the preferential right is not due under the
         applicable agreement until after Closing, the affected Property shall
         be conveyed to and purchased by Buyer at Closing pursuant to the terms
         of this Agreement subject to the terms of the applicable preferential
         right to purchase. After Closing, Buyer shall, if necessary, provide
         notice to the appropriate third parties requesting waiver of the
         applicable preferential rights to purchase and/or comply with the terms
         of the preferential rights to purchase that are properly exercised
         after Closing, with Buyer receiving all consideration payable upon the
         exercise of such preferential rights to purchase.

                  (e) For a period of one (1) year after the Closing Date,
         Buyer, or its successor who expressly assumes its obligations and
         liabilities hereunder, shall maintain its corporate or other legal
         status and shall at all times own assets having a value net of
         liabilities of not less than $50,000,000.

                  (f) BUYER AGREES TO INDEMNIFY, RELEASE, DEFEND AND HOLD
         HARMLESS SELLER, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
         REPRESENTATIVES, AFFILIATES, SUBSIDIARIES, SUCCESSORS AND ASSIGNS FROM
         AND AGAINST ANY CLAIMS, LIABILITIES, LOSSES, DAMAGES, COSTS AND
         EXPENSES (INCLUDING WITHOUT LIMITATION, DAMAGE TO PROPERTY, OR INJURY
         OR DEATH OF PERSONS, COURT COSTS, REASONABLE ATTORNEY'S FEES AND
         EXPENSES OF EXPERTS) CAUSED BY, ARISING FROM OR ATTRIBUTABLE TO THE
         BREACH BY BUYER OF ANY OF ITS OBLIGATIONS UNDER THIS AGREEMENT OR THE
         OWNERSHIP OR OPERATION OF THE PROPERTIES AFTER THE EFFECTIVE TIME,
         REGARDLESS OF WHETHER SUCH CLAIMS, LIABILITIES, LOSSES, DAMAGES, COSTS
         OR EXPENSES ARE DUE IN WHOLE OR IN PART TO THE NEGLIGENCE OF SELLER.

         8.05 - SELLER'S POST-CLOSING OBLIGATIONS.

                  (a) If at any time subsequent to the Closing, Seller comes
         into possession of money or property belonging to the Buyer that was
         not previously accounted for by credit or adjustment according to this
         Agreement such money or other property shall be promptly delivered to
         the Buyer.

                  (b) Except for the obligations assumed by Buyer pursuant to
         Section 8.04 hereof, Seller shall be responsible for and discharge (i)
         Environmental Liabilities as defined


                                       24
<PAGE>   28
         in Section 8.04(b) hereof, and in connection therewith, Buyer shall
         allow Seller reasonable access to the Properties effected by the
         Environmental Liabilities to conduct clean-up and remedial operations,
         and (ii) all other claims, costs, expenses and liabilities with respect
         to the Properties which accrue or relate to the times prior to the

                  (a) When any claim, action, or suit shall be filed or asserted
         in writing against any party which is indemnifiable under the terms of
         this Agreement, the indemnified party shall promptly notify the
         indemnifying party of the same in writing, specifying in detail the
         basis of such claim and the facts pertaining thereto, and the
         indemnifying party shall, at its option, have the right to assume the
         defense thereof or participate in the defense thereof and to employ its
         own legal counsel in connection with such defense. Failure of the
         indemnified party to notify the indemnifying party of such claim,
         action, or suit within twenty (20) calendar days after notice to the
         indemnified party of such claim, action, or suit shall constitute a
         waiver of its rights under this Article, unless such failure to notify
         within such time period shall not prejudice the rights of the
         indemnifying party in respect of such claim, action or suit, in which
         case prompt notification as provided above shall be sufficient.


                                       28
<PAGE>   32
                  (b) The indemnified party shall have the right to employ
         counsel separate from counsel employed by the indemnifying party in any
         such action and to participate in the defense thereof, but the fees and
         expenses of such counsel employed by the indemnified party shall be at
         the sole expense of the indemnified party unless (i) the indemnifying
         party shall have elected not or shall have failed to assume or
         participate in the defense thereof, (ii) the employment thereof has
         been specifically authorized by the indemnifying party in writing, or
         (iii) the parties to any such action (including any impleaded parties)
         include both the indemnifying and indemnified party, and the
         indemnified party shall have been advised by its counsel that there may
         be one or more legal defenses available to it which are different from
         or additional to those available to the indemnifying party (in any
         which case (i), (ii) or (iii) above the indemnifying party shall not
         have the right to assume the defense of such action on behalf of the
         indemnified party and the fees and expenses of such counsel employed by
         the indemnified party shall be at the sole expense of the indemnifying
         party).

                  (c) Prior to effectuating any settlement of any such action or
         proceeding, the indemnified party shall furnish the indemnifying party
         with written notice of any proposed settlement in sufficient time to
         allow the indemnifying party to act thereon. The indemnifying party
         shall not be liable for any settlement of any such action or proceeding
         effected without the written consent of the indemnifying party. The
         indemnifying party shall not effect a settlement of any claim without
         the written consent of the indemnified party unless the indemnifying
         party secures the complete release of the indemnified party as a part
         of such settlement.




         11.02 - CLAIM REIMBURSEMENT AND REDUCTION.

                  (a) Should the indemnified party realize any benefit,
         including any tax benefit, resulting from any loss, liability, cost or
         damage for which such indemnified party has been indemnified under this
         Article, such indemnified party shall reimburse the indemnifying party,
         at the time such benefit is realized, an amount equal to the dollar
         amount of such benefit so realized.

                  (b) Any claim shall be reduced to the extent of any third
         party insurance or condemnation payment actually received by the
         indemnified party or, alternatively, at the option of the indemnified
         party, the rights of the indemnified party against any insurer or
         governmental unit with respect to such claim shall be assigned to the
         indemnifying party.
