                               PROSPECTUS SUMMARY
 
The following summary is qualified in its entirety by, and should be read in
conjunction with, the more detailed information and financial statements,
including the notes thereto, appearing elsewhere in this Prospectus. Unless
otherwise indicated, the information in this Prospectus (i) gives effect to the
combination (the "Combination Transaction") in September 1997 of Araxas Energy
Corporation ("Araxas"), South Coast Exploration Company ("South Coast"), SOCO
Exploration, L.P. ("SOCO") and Interactive Exploration Solutions, Inc. ("INEXS"
and, together with South Coast and SOCO, the "South Coast Companies"), (ii)
assumes that the Underwriters' over-allotment option will not be exercised and
(iii) has been adjusted to reflect the     -for-      split of the Common Stock
effected in        1997. Unless otherwise indicated by the context, references
herein to the "Company" or "XPLOR" are to XPLOR Energy, Inc., a Delaware
corporation, and its corporate and partnership subsidiaries and predecessors,
and information with respect to the reserves and operating history of the
Company includes the combined reserves and operating history of Araxas and the
South Coast Companies. Certain terms used herein relating to the oil and gas
industry are defined in the Glossary of Certain Industry Terms included
elsewhere in this Prospectus.
 
                                  THE COMPANY
 
XPLOR is an independent energy company engaged in the exploration for and
development of oil and gas reserves, primarily in the Louisiana and Texas Gulf
Coast region. The Company focuses on growth through drilling, combining
sophisticated technologies such as 3-D seismic data and interactive computer
analytical techniques with an experienced technical staff and management. XPLOR
applies a disciplined exploration methodology consisting of traditional
subsurface geology followed by acquisition and analysis of specifically
targeted 3-D seismic data, integrated with sound engineering and economic
principles. This methodology is designed to use 3-D seismic data cost-
effectively to confirm rather than to generate prospects.
 
XPLOR was formed through the strategic combination of Araxas and the South
Coast Companies in the Combination Transaction. Management believes that the
Combination Transaction will enhance the Company's ability to increase its
reserves, production and cash flow per share by combining the complementary
strengths of Araxas's operating expertise, the South Coast Companies'
geophysical expertise and the two companies' portfolios of exploration
prospects concentrated in the Gulf Coast region.
 
Between December 31, 1994 and September 30, 1997, the Company increased its net
proved reserves from approximately 8 Bcfe to approximately 58 Bcfe. Average net
production increased from 280 Mcfe per day for the year ended December 31, 1994
to approximately 9,500 Mcfe per day for the nine months ended September 30,
1997.
 
Drilling new wells and interpreting 3-D seismic and other data over existing
fields have together generated approximately 60% of the increase in the
Company's estimated proved reserves from December 31, 1994 to September 30,
1997. The Company drilled 48 gross wells during that time, consisting of 29
exploratory wells, of which 15 were commercially productive, and 19 development
wells, of which 17 were commercially productive. The Company also has added
reserves through acquisitions, which accounted for the balance of the reserve
increase from December 31, 1994 to September 30, 1997. During this period, the
Company completed major acquisitions of substantial working interests in the
Adams-Baggett field in Crockett County, Texas, and the Main Pass 35 field in
the shallow state waters of Louisiana. The Company's reserve growth has been
achieved at an average finding cost of $0.72 per Mcfe and an average
acquisition cost of $0.70 per Mcfe. Although the Company expects that its
future reserve and production growth will result primarily from its drilling
program, the Company will consider acquisitions with significant growth
potential.
 
The Company has acquired over 700 square miles of 3-D seismic data and has
leased or optioned acreage in 17 project areas. Within these project areas,
XPLOR currently has 98 exploration and development prospects
 
                                       4
<PAGE>
 
scheduled to be drilled over the next two to three years. Prior to the
Offering, capital constraints limited the Company's ability to drill its
prospect inventory. At the closing of this Offering, however, the Company
expects to have available for its drilling program $   million in net proceeds
from the Offering and an additional $20.0 million available for borrowing under
the Company's revolving credit facility. XPLOR has budgeted total capital
expenditures of approximately $41.0 million through the end of 1998, which
includes funds for drilling approximately 80% of its currently identified
exploration and development prospects. The Company believes that its current
prospect inventory includes both moderate potential, lower risk prospects and
higher potential, higher risk prospects that, if successful, may result in
significant increases in proved reserves.
 
                                   STRENGTHS
 
XPLOR believes it has the following strengths that are integral to its overall
growth strategy:
 
Experienced Technical Team
 
The Company has assembled a technical team that has extensive experience in
applying sophisticated exploration techniques and that it believes has the
capacity to adapt to rapidly changing technological demands. The Company
employs 11 geoscientists, consisting of four geologists and seven
geophysicists, all of whom have 15 to 25 years of experience in exploring for
oil and gas. The Company also has an experienced group of engineers who
participate in the evaluation of the Company's potential projects and also
manage the Company's drilling and production operations.
 
Advanced Technology
 
The Company's experienced technical team applies advanced technology in oil and
gas exploration and has access to the latest enhancements in such technologies.
The Company provides its technical team with a sophisticated in-house computer-
based work environment, which enables the team to evaluate and integrate data
efficiently. XPLOR has a networked environment consisting of 10 workstations
running the latest 3-D design, modeling, interpretation, mapping, processing
and visualization software applications.
 
INEXS, the Company's geophysical consulting subsidiary, is an integral part of
the Company's technology base and gives the Company access to the latest
advances in geoscientific technologies. INEXS has specialized in 3-D seismic
interpretation and project management services since 1990 and has interpreted
over 180 3-D seismic surveys for over 133 companies, including major
integrated, foreign national and independent oil and gas companies. INEXS's
clients have drilled more than 100 wells based on INEXS's interpretation work,
over 70% of which the Company believes have been completed as commercial
producers. As a result of this high level of activity, INEXS has formed working
relationships with a number of technology providers. Consequently, INEXS has
participated in the design and testing of new applications, providing access to
emerging technologies prior to their availability for general use.
 
Existing Prospect Inventory and Proved Reserves
 
XPLOR has an existing inventory of 98 exploration and development prospects
scheduled to be drilled within the next two to three years. The Company has
leased or optioned acreage for all 98 prospects. Of these prospects, 70 are
exploratory and 28 are development. The Company also has identified additional
exploratory prospects in various stages of evaluation, planning and
implementation. The Company had total proved reserves of approximately 58 Bcfe
at September 30, 1997, of which approximately 29 Bcfe were proved developed.
For the nine months ended September 30, 1997, net production averaged
approximately 9,500 Mcfe per day.
 
Experienced Management
 
XPLOR's executive management has experience in both traditional exploratory and
operational areas and in the application of the latest technological advances.
The Company's executive management has an average of over 20
 
                                       5
<PAGE>
 
years of industry experience in engineering, geology, geophysics and finance,
primarily with major integrated and large independent oil and gas companies.
The Company has established both short-term and long-term incentive plans for
management designed to align compensation with the interests of stockholders.
 
                               BUSINESS STRATEGY
 
XPLOR intends to increase its oil and gas reserves, production and cash flow
per share by emphasizing the following:
 
Growth Through Exploration and Development
 
The Company believes that its future growth in reserves, production and cash
flow per share will result principally from a combination of exploratory and
development drilling on the Company's inventory of prospects. In addition to
its 98 exploration and development prospects scheduled to be drilled over the
next two to three years, the Company has identified additional exploratory
prospects in various phases of evaluation, planning and implementation. The
Company follows a disciplined methodology for the evaluation of its prospects.
The methodology comprises four phases: (i) identification of prospects in
prolific trends with a high density of potential reservoirs and traps; (ii)
data acquisition and quality control; (iii) data integration and
interdisciplinary review; and (iv) final decision-making based upon a thorough
analysis of economic and technical information.
 
Prospect Generation
 
XPLOR seeks to generate internally the majority of the prospects in which it
participates. This focus on internal prospect generation enables the Company to
control the entire process, from idea formulation to management of prospective
risk and drilling decisions. The Company focuses on defining prospects that
have multiple objectives based on subsurface geology before acquiring 3-D
seismic data. The Company's inventory of prospects has also enabled the Company
to trade for additional desirable prospects held by other oil and gas
companies. In addition, third-party evaluations performed by INEXS provide the
Company with opportunities to participate in exploratory prospects with
industry partners. XPLOR may also pursue acquisition opportunities with
significant growth potential.
 
Balanced Drilling Program
 
The Company engages in an active drilling program and attempts to maintain a
balanced portfolio of exploratory and development prospects. The Company's
exploratory prospect portfolio consists of both moderate potential, lower risk
prospects and higher potential, higher risk prospects that, if successful, may
result in significant increases in proved reserves. The Company considers
balancing the relationship between risk and reward in its exploration program
an important component of its business strategy.
 
Geographic Focus
 
XPLOR's operating activities are focused onshore and in state waters along the
Gulf Coast, primarily in Louisiana and Texas, where the Company has substantial
technical experience and expertise. Given the region's prolific production
history, the existing infrastructure and the opportunities that have been
created by advances in seismic and drilling technology, the Company believes
that the Gulf Coast represents one of the most attractive exploration regions
in North America. The Company has access to an extensive technical database of
well logs, production information and speculative seismic data for the Gulf
Coast region, and has assembled a technical staff with substantial experience
and expertise in the area. From January 1, 1994 to September 30, 1997, the
Company drilled 42 wells along the Gulf Coast and acquired a database of
geological and engineering data and approximately 400 square miles of 3-D
seismic data in the region.

                          THE COMBINATION TRANSACTION
 
All of the operations of the Company were previously conducted through Araxas
and the South Coast Companies, the interests of which were acquired, directly
or indirectly, by the Company in the Combination Transaction. An aggregate of
   shares of Common Stock and $3.0 million aggregate principal amount of the
Company's notes (the "Combination Notes") were issued in exchange for such
acquired interests. As a result of the Combination Transaction, Araxas and the
South Coast Companies became wholly owned subsidiaries of XPLOR. See "The
Combination Transaction."

                              SUMMARY RESERVE DATA
 
The following table sets forth summary data with respect to the Company's
estimated net proved oil and gas reserves and the estimated future net pretax
cash flows attributable thereto as of December 31, 1996, on a combined basis
giving effect to the Combination Transaction, and as of September 30, 1997. See
"The Combination Transaction." All information in this Prospectus relating to
estimated net proved oil and gas reserves as of December 31, 1996 and September
30, 1997 and the estimated future net revenues attributable thereto is based
upon the reserve reports (the "Netherland Sewell Reports") prepared by
Netherland, Sewell & Associates, Inc. ("Netherland Sewell") for XPLOR. A
summary of the Netherland Sewell Report with respect to reserves as of
September 30, 1997 is included as Appendix A to this Prospectus. All
calculations of estimated net proved reserves have been made in accordance with
applicable requirements of the Securities and Exchange Commission (the
"Commission") and, except as otherwise indicated, give no effect to federal or
state income taxes otherwise attributable to estimated future net revenues from
the sale of oil and gas. There are numerous uncertainties inherent in
estimating quantities of proved reserves and in projecting future rates of
production and timing of development expenditures, including many factors
beyond the control of the Company. See "Risk Factors--Uncertainty of Reserve
Information and Future Net Revenue Estimates" and "Business--Oil and Gas
Reserves."

(1) The prices used as of December 31, 1996 averaged $24.23 per Bbl of oil and
$3.97 per Mcf of gas and do not give effect to hedging arrangements required by
the Company's former debt agreement. During September 1997, the Company closed
all of its outstanding hedging arrangements. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Hedging" and
"Business--Marketing." Giving effect to such hedging arrangements, the prices
used as of December 31, 1996 would have been $18.10 per Bbl of oil and $3.49
per Mcf of gas, and estimated future net revenues before income taxes and
present value of estimated future net revenues before income taxes as of such
date would have been $158,732,000 and $86,534,000, respectively.
(2) The prices used as of September 30, 1997 averaged $19.93 per Bbl of oil and
$2.60 per Mcf of gas.
(3) The declines in proved reserves from December 31, 1996 to September 30,
1997 reflect production during the period and the exclusion of certain reserves
that were no longer economic at September 30, 1997 prices. During this period,
the Company's capital constraints limited additions to proved reserves.
(4) The present value of estimated future net revenues attributable to the
Company's reserves was prepared using constant prices as of the calculation
date (see Note 1), discounted at 10% per annum on a pretax basis.

                                  RISK FACTORS
 
This Prospectus contains certain forward-looking statements. These statements
include, among others, statements regarding oil and gas reserves, future
drilling and operations, future production of oil and gas, future net cash
flows and future capital expenditures. Actual results could differ materially
from those projected in the forward-looking statements as a result of various
factors, including, without limitation, those set forth below and elsewhere in
this Prospectus. Prospective investors should carefully consider the following
factors, in addition to other information contained in this Prospectus, in
connection with an investment in the shares of Common Stock offered hereby.
 
DEPENDENCE ON EXPLORATORY DRILLING ACTIVITIES
 
The success of the Company will be materially dependent upon the success of its
exploratory drilling program, which will be funded in part with the proceeds
from the Offering. Exploratory drilling involves numerous risks, including the
risk that no commercially productive oil or gas reservoirs will be encountered.
The cost of drilling, completing and operating wells is often uncertain, and
drilling operations may be curtailed, delayed or canceled as a result of a
variety of factors, including unexpected drilling conditions, pressure or
irregularities in formations, equipment failures or accidents, adverse weather
conditions, compliance with governmental requirements and shortages or delays
in the availability of drilling rigs and the delivery of equipment. Although
the Company believes that its use of 3-D seismic data and other advanced
technologies should increase the probability of success of its exploratory
wells and should reduce average finding and development costs through
elimination of marginal or uneconomic prospects that might have otherwise been
drilled solely on the basis of 2-D seismic data and other traditional methods,
exploratory drilling remains a speculative activity. Even when fully utilized
and properly interpreted, 3-D seismic data and other advanced technologies only
assist geoscientists in identifying subsurface structures and do not enable the
interpreter to determine whether hydrocarbons are in fact present in such
structures. In addition, the use of 3-D seismic data and other advanced
technologies requires greater pre-drilling expenditures than traditional
drilling strategies, and the Company could incur losses as a result of such
expenditures. Moreover, the Company may identify prospects through a number of
methods that do not include interpretation of 3-D seismic data or the use of
other advanced technologies. The Company's future drilling activities may not
be successful, and if unsuccessful, such failure will have a material adverse
effect on the Company's results of operations and financial condition. There
can be no assurance that the Company's overall drilling success rate or its
drilling success rate for activity within a particular project area will not
decline. The Company may choose not to acquire option and lease rights prior to
acquiring seismic data and may identify a prospect or drilling location before
seeking option or lease rights in the prospect or location. Although the
Company has identified or budgeted for numerous drilling prospects, there can
be no assurance that such prospects will ever be drilled (or drilled within the
scheduled time frame) or that oil or gas will be produced from any such
prospects or any other prospects. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
VOLATILITY OF OIL AND GAS PRICES
 
The Company's revenues, future rate of growth, results of operations, financial
condition and ability to borrow funds or obtain additional capital, as well as
the carrying value of its properties, are substantially dependent upon
prevailing prices of oil and gas. Historically, the markets for oil and gas
have been volatile, and such markets are likely to continue to be volatile in
the future. Prices for oil and gas are subject to wide 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 the level of consumer product demand, weather
conditions, domestic and foreign governmental regulations, the price and
availability of alternative fuels, political conditions in the Middle East, the
foreign supply of oil and gas, the price of foreign imports and overall
economic conditions. It is impossible to predict future oil and gas price
movements with certainty. Declines in oil and gas prices may materially
adversely affect the Company's financial condition, liquidity, ability to
finance planned capital expenditures and results of operations. Lower oil and
gas prices also may reduce the amount of oil and gas that the Company can
produce economically. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business--Marketing."
 
                                       11
<PAGE>
 
The Company periodically reviews the carrying value of its oil and gas
properties under the full cost accounting rules of the Commission. Under these
rules, capitalized costs of proved oil and gas properties may not exceed the
present value of estimated future net revenues from proved reserves, discounted
at 10%. Application of this "ceiling" test generally requires pricing future
revenue at the unescalated prices in effect as of the end of each fiscal
quarter and requires a write-down for accounting purposes if the ceiling is
exceeded, even if prices were depressed for only a short period of time. The
Company may be required to write down the carrying value of its oil and gas
properties when oil and gas prices are depressed or unusually volatile, which
would result in a charge to earnings but would not affect cash flow from
operating activities. Once incurred, a write-down of oil and gas properties is
not reversible at a later date.
 
The Company's former debt agreement required the Company to put into place
significant long-term hedging arrangements in an effort to reduce the effects
of short-term fluctuations in the price of oil and gas. Such arrangements were
required at the closing of such financing and at the times of additional
drawdowns thereunder. The Company repaid and terminated its former debt
agreement in September 1997, and the Company's current credit facility does not
require the Company to maintain hedges. During September 1997, the Company
closed all its outstanding hedging arrangements, resulting in losses of $2.8
million. The Company currently does not intend to hedge more than one-third of
its production, but may reevaluate its hedging policy from time to time. The
Company may also close out any portion of hedges that may exist from time to
time as determined to be appropriate by management. Any future hedging
arrangements would apply to only a portion of the Company's production and
would provide only partial price protection against declines in oil and gas
prices. Such hedging may expose the Company to risk of financial loss in
certain circumstances, including instances where production is less than
expected, where the Company's customers fail to purchase contracted quantities
of oil or gas or where a sudden, unexpected event materially affects oil or gas
prices. In addition, such hedging would limit the benefit to the Company of
increases in the price of oil and gas. During the year ended December 31, 1996,
the Company received a fixed price and paid the New York Mercantile Exchange
("NYMEX") price with respect to 575 MMBtus of gas and 60 MBbls of oil under
commodity price arrangements, realizing losses of $598,000. During the first
six months of 1997, the Company received a fixed price and paid the NYMEX price
with respect to 338 MMBtus of gas and 177 MBbls of oil under commodity price
swap arrangements, realizing losses of $739,000. The Company did not engage in
hedging prior to 1996. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Hedging" and "Business--Marketing."
 
RESERVE REPLACEMENT RISK
 
In general, the volume of production from oil and gas properties declines as
reserves are depleted, with the rate of decline depending on reservoir
characteristics. Except to the extent the Company conducts successful
exploration and development activities or acquires properties containing proved
reserves, or both, the proved reserves of the Company will decline as reserves
are produced. The Company's future oil and gas production is, therefore, highly
dependent upon its level of success in finding or acquiring additional
reserves. The business of exploring for, developing or acquiring reserves is
capital intensive. During 1997, the Company's capital constraints have limited
its ability to add to proved reserves. 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 investment to maintain or
expand its asset base of oil and gas reserves would be impaired. In addition,
there can be no assurance that the Company's future exploration, development
and acquisition activities will result in additional proved reserves or that
the Company will be able to drill productive wells at acceptable costs.
Furthermore, although the Company's revenues could increase if prevailing
prices for oil and gas increase significantly, the Company's finding and
development costs could also increase. Of the Company's 98 currently identified
drilling prospects, approximately 80% (representing approximately 55% of the
Company's estimated capital drilling expenditures for such projects) are
operated by parties other than the Company. As nonoperator, the Company has
less control over the timing of drilling and other operations on such prospects
than if it were the operator of such properties. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

UNCERTAINTY OF RESERVE INFORMATION AND FUTURE NET REVENUE ESTIMATES
 
There are numerous uncertainties inherent in estimating oil and gas reserves
and their values, including many factors beyond the control of the producer.
The reserve data set forth in this Prospectus represent estimates only.
Reservoir engineering is a subjective process of estimating underground
accumulations of oil and gas that cannot be measured in an exact manner.
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. For these reasons, estimates of the economically recoverable
quantities of oil and gas attributable to any particular group of properties,
classifications of such reserves based on risk of recovery, and estimates of
the future net cash flows expected therefrom prepared by different engineers or
by the same engineers but at different times may vary substantially and such
reserve estimates may be subject to downward or upward adjustment based upon
such factors. Actual production, revenues and expenditures with respect to the
Company's reserves will likely vary from estimates, and such variances may be
material. In addition, the 10% discount factor, which is required by the
Commission to be used in calculating discounted future net cash flows for
reporting purposes, is not necessarily the most appropriate discount factor
based on interest rates in effect from time to time and risks associated with
the Company or the oil and gas industry in general. See "Business--Oil and Gas
Reserves."
 
SHORTAGES OF RIGS, EQUIPMENT, SUPPLIES AND PERSONNEL
 
There is a general shortage of drilling rigs, equipment and supplies, which the
Company believes may intensify. The costs and delivery times of rigs, equipment
and supplies are substantially greater than in prior periods and are currently
escalating. Shortages of drilling rigs, equipment or supplies could delay and
adversely affect the Company's exploration and development operations, which
could have a material adverse effect on its financial condition and results of
operations.
 
The demand for, and wage rates of, qualified rig crews have begun to rise in
the drilling industry in response to the increasing number of active rigs in
service. Such shortages have in the past occurred in the industry in times of
increasing demand for drilling services. If the number of active drilling rigs
continues to increase, the oil and gas industry may experience shortages of
qualified personnel to operate drilling rigs, which could delay the Company's
drilling operations and adversely affect the Company's financial condition and
results of operations.
 
OPERATING RISKS OF OIL AND GAS OPERATIONS
 
The oil and gas business involves certain operating hazards such as well
blowouts, craterings, explosions, uncontrollable flows of oil, gas or well
fluids, fires, formations with abnormal pressures, pipeline ruptures or spills,
pollution, releases of toxic gas and other environmental hazards and risks, any
of which could result in substantial losses to the Company. In addition, the
Company may be liable for environmental damages caused by previous owners of
property purchased and leased by the Company. As a result, substantial
liabilities to third parties or governmental entities may be incurred, the
payment of which could reduce or eliminate the funds available for exploration,
development or acquisitions or result in the loss of the Company's properties.
In accordance with customary industry practices, the Company maintains
insurance against some, but not all, of such risks and losses. The Company may
elect to self-insure if management believes that the cost of insurance,
although available, is excessive relative to the risks presented. In addition,
pollution and environmental risks generally are not fully insurable. The
Company carries limited business interruption insurance. The occurrence of an
event not fully covered by insurance could have a material adverse effect on
the financial condition and results of operations of the Company. See
"Business--Operating Hazards and Insurance."
 
The availability of a ready market for the Company's oil and gas production
depends on the proximity of reserves to, and the capacity of, oil and gas
gathering systems, pipelines and trucking or terminal facilities. The Company
delivers gas through gas gathering systems and gas pipelines that it does not
own. Federal and state regulation of
 
                                       13
<PAGE>
 
gas and oil production and transportation, tax and energy policies, changes in
supply and demand and general economic conditions all could adversely affect
the Company's ability to produce and market its oil and gas.
 
CURRENT CONCENTRATION OF PRODUCING PROPERTIES
 
Approximately 33% of the Company's average daily net production for the nine
months ended September 30, 1997 was attributable to Main Pass 35. As of
September 30, 1997, approximately 30% of the Company's proved reserves were
associated with this field. Consequently, the Company's future results of
operations are significantly dependent upon the future performance of Main Pass
35. In the third quarter of 1997, the field was shut in for a period of three
days due to a hurricane, and otherwise experienced curtailments of production
due to temporary capacity constraints of its water injection system. As a
result, average net production attributable to the field decreased from 580 BOE
per day in the second quarter of 1997 to 420 BOE per day in the third quarter
of 1997. Since acquiring the field in August 1996, the Company has expended
approximately $1.0 million to upgrade the operating equipment. If the Company's
operations in Main Pass 35 are adversely affected by future events that
increase costs, reduce availability of equipment or supplies, restrict drilling
activity or limit production, the Company could experience a material adverse
impact on its financial condition and results of operations.
 
DEPENDENCE ON KEY PERSONNEL
 
The Company depends to a large extent on the services of certain key management
personnel, the loss of any of which could have a material adverse effect on the
Company's operations. Prior to the Offering, the Company entered into
employment agreements with each of Mr. Steven W. Nance (the Company's President
and Chief Executive Officer), Mr. Ron A. Krenzke (the Company's Executive Vice
President and Chief Operating Officer) and Mr. Stephen M. Clark (the Company's
Vice President, Chief Financial Officer, Secretary and Treasurer) described
herein under "Management--Employment Agreements." The Company does not maintain
key-man life insurance with respect to any of its employees. The Company
believes that its success is also dependent upon its ability to continue to
employ and retain skilled technical personnel. See "Business--Strengths."
 
ABILITY TO MANAGE GROWTH AND ACHIEVE BUSINESS STRATEGY
 
The Company has experienced significant growth in the recent past through the
expansion of its 3-D seismic data acquisition and drilling program. The
Company's rapid growth has placed, and is expected to continue to place, a
significant strain on the Company's financial, technical, operational and
administrative resources. The Company has relied in the past and expects to
continue to rely to a certain extent on project partners and independent
contractors that have provided the Company with land acquisition, drilling and
other services. At September 30, 1997, the Company had 32 full-time employees
and seven contract employees. As the Company increases the number of projects
it is evaluating or in which it is participating, there will be additional
demands on the Company's financial, technical, operational and administrative
resources and continued reliance by the Company on project partners and
independent contractors, and these strains on resources, additional demands and
continued reliance may negatively affect the Company. The Company's ability to
continue its growth will depend upon a number of factors, including its ability
to obtain leases or options on properties for 3-D seismic surveys, its ability
to acquire additional 3-D seismic data, its ability to identify and acquire new
exploratory sites, its ability to develop existing sites, its ability to
continue to retain and attract skilled personnel, its ability to maintain or
enter into new relationships with project partners and independent contractors,
the results of its drilling program, hydrocarbon prices, access to capital and
other factors. There can be no assurance that the Company will be successful in
achieving growth or any other aspect of its business strategy.
 
LIMITED COMBINED OPERATING HISTORY
 
The Company was organized in July 1997 to consolidate and continue the
activities previously conducted by Araxas and the South Coast Companies. Prior
to the Combination Transaction, Araxas and the South Coast Companies operated
as separate, independent businesses. The historical financial results of Araxas
and the South Coast Companies cover periods when such companies were not under
common control or management and, therefore, may not be indicative of the
Company's future financial or operating results. Moreover, there can be no
 
                                       14
<PAGE>
 
assurance that the consolidation of the management and administrative functions
of Araxas and the South Coast Companies will be successful or that the
Company's management will be able to manage the operations of the combined
entity effectively or profitably.
 
RELIANCE ON TECHNOLOGICAL DEVELOPMENT AND POSSIBLE TECHNOLOGICAL OBSOLESCENCE
 
The Company's business is dependent upon utilization of changing technology. As
a result, the Company's ability to adapt to evolving technologies, obtain new
products and maintain technological advantages will be important to its future
success. The Company believes that its ability to use advanced technologies
currently gives it an advantage over many of its competitors. This advantage,
however, is based in part upon technologies developed by others, and the
Company may not be able to maintain this advantage. As new technologies
develop, the Company may be placed at a competitive disadvantage, and
competitive pressures may force the Company to implement such new technologies
at substantial cost. There can be no assurance that the Company will be able to
use successfully, or expend the financial resources necessary to acquire, new
technology, that others will not achieve technological expertise comparable to
or exceeding that of the Company or that others will not implement new
technologies before the Company. One or more of the technologies currently used
by the Company or implemented in the future may become obsolete. In such case,
the Company's business, financial condition and results of operations could be
materially adversely affected. If the Company is unable to use the most
advanced commercially available technology, the Company's business, financial
condition and results of operations could be materially and adversely affected.
See "Business--Strengths--Advanced Technology."
 
SIGNIFICANT CAPITAL REQUIREMENTS
 
The Company has experienced and expects to continue to experience substantial
working capital needs, particularly as a result of its active 3-D seismic data
acquisition and drilling program. Although the Company believes that the net
proceeds from the Offering, cash flow from operations and its existing credit
arrangements should allow the Company to implement its current business
strategy, additional financing may be required in the future to fund the
Company's growth. No assurances can be given as to the availability or terms of
any such additional financing that may be required or that financing will
continue to be available under existing credit arrangements. In the event such
capital resources are not available to the Company, its drilling, development
and other activities may be curtailed. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
 
CONTROL BY CERTAIN STOCKHOLDERS
 
Upon completion of the Offering, the Company's officers and directors will
beneficially own approximately   % (  % if the Underwriters' over-allotment
option is exercised in full) of the outstanding shares of Common Stock, and
Equitable Resources, Inc., through its subsidiaries (collectively,
"Equitable"), and New West Resources, Inc. ("New West") will beneficially own
approximately   % and   %, respectively (  %, and   %, respectively, if the
Underwriters' over-allotment option is exercised in full), of the outstanding
shares. As a result, such stockholders will be in a position to influence
significantly or to control the outcome of certain matters requiring a
stockholder vote, including the election of directors, the adoption or
amendment of provisions in the Company's Certificate of Incorporation or Bylaws
and the approval of mergers and other significant corporate transactions. Such
ownership of Common Stock may have the effect of delaying, deferring or
preventing a change in control of the Company and may adversely affect the
voting and other rights of other stockholders. See "Principal Stockholders."
 
GOVERNMENT REGULATION AND ENVIRONMENTAL MATTERS
 
Oil and gas operations are subject to various federal, state and local
governmental regulations, which may be changed from time to time in response to
economic or political conditions. Matters subject to regulation include
discharge permits for drilling operations, drilling bonds, reports concerning
operations, the spacing of wells, unitization and pooling of properties and
taxation. From time to time, regulatory agencies have imposed price controls
and limitations on production by restricting the rate of flow of oil and gas
wells below actual production
 
                                       15
<PAGE>
 
capacity to conserve supplies of oil and gas. The Company is also subject to
changing and extensive tax laws, the effects of which cannot be predicted.
Legal requirements are frequently changed and subject to interpretation, and
the Company is unable to predict the ultimate cost of compliance with these
requirements or their effect on its operations. No assurance can be given that
existing laws or regulations, as currently interpreted or reinterpreted in the
future, or future laws or regulations will not materially adversely affect the
Company's results of operations and financial condition. The development,
production, handling, storage, transportation and disposal of oil and gas, by-
products thereof and other substances and materials produced or used in
connection with oil and gas operations are subject to federal, state and local
laws and regulations primarily relating to protection of human health and the
environment. The discharge of oil, gas or pollutants into the air, soil or
water may give rise to significant liabilities on the part of the Company to
the government and third parties and may require the Company to incur
substantial costs of remediation. See "Business--Regulation."
 
COMPETITION
 
The Company encounters competition from other oil and gas companies in all
areas of its operations, including the acquisition of exploratory prospects and
proven properties. The Company's competitors include major integrated oil and
gas companies, numerous independent oil and gas companies, individuals and
drilling and income programs. Many of its competitors are large, well-
established companies that have substantially larger operating staffs and
greater capital resources than those of the Company and that, in many
instances, have been engaged in the oil and gas business for a much longer time
than the Company. Such companies may be able to pay more for exploratory
prospects and productive oil and gas properties and may be able to define,
evaluate, bid for and purchase a greater number of properties and prospects
than the Company's financial or human resources permit. In addition, such
companies may be able to expend greater resources on the existing and changing
technologies that the Company believes are and will be increasingly important
to the current and future success of oil and gas companies. The Company's
ability to explore for oil and gas prospects and to acquire additional
properties in the future will be dependent upon its ability to conduct its
operations, to evaluate and select suitable properties and to consummate
transactions in this highly competitive environment. See "Business--
Competition."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
Sales of substantial amounts of Common Stock in the public market after the
closing of the Offering could adversely affect the market price of the Common
Stock. Upon the completion of the Offering, the Company will have a total of
    shares of Common Stock outstanding. Of these shares, the     shares of
Common Stock offered hereby (    shares if the Underwriters' over-allotment
option is exercised in full) will be freely tradeable without restrictions or
registration under the Securities Act by persons other than "affiliates" of the
Company, as defined under the Securities Act. The remaining     shares of
Common Stock outstanding will be restricted securities as that term is defined
by Rule 144 as promulgated under the Securities Act ("Rule 144"). In addition,
    shares of Common Stock may be issued pursuant to options issued under the
Company's Incentive Plan and options and warrants not included under the
Incentive Plan. The Company anticipates that the     shares of Common Stock
issuable upon exercise of outstanding options will become available for future
sale in the public market pursuant to a subsequently filed registration
statement on Form S-8. See "Management--Executive Compensation."
 
Under Rule 144 (and subject to certain volume limitations, manner of sale and
other requirements related to the sale of securities), the     restricted
shares will become eligible for sale in September 1998, or one year following
the consummation of the Combination Transaction. The Company also has entered
into registration rights agreements with certain of the Company's current
stockholders who own approximately     shares of Common Stock and with certain
holders of options and warrants to purchase     shares of Common Stock,
pursuant to which such persons have received demand and "piggyback"
registration rights that provide for the registration of the resale of such
shares at the Company's expense. See "Certain Transactions--Registration
Rights." The Company, substantially all of its existing stockholders and
certain other persons have agreed, however, to certain restrictions relating to
the sale of their Common Stock for a period of 180 days following the date of
this Prospectus. See "Underwriting." Future sales of substantial amounts of
Common Stock in the public

market following this Offering, or the expectation of such sales or the
availability of shares for sale, could adversely affect the market price of the
Common Stock. For further information concerning Common Stock available for
resale after this Offering, see "Shares Eligible for Future Sale."
 
NO INTENTION TO PAY DIVIDENDS
 
The Company currently intends to retain any earnings for the future operation
and development of its business and does not currently intend to declare or pay
any dividends on its Common Stock in the foreseeable future. In addition, the
payment of dividends by the Company is restricted by the Company's credit
facility. See "Dividend Policy" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
RECENT LOSSES
 
On a pro forma basis, the Company incurred net losses for the year ended
December 31, 1996 and the six months ended June 30, 1997. Araxas incurred net
losses in each of the last two years. Although the South Coast Companies have
had net income on a combined basis in each of such years, there can be no
assurance that the Company will be profitable in the future. See "Unaudited Pro
Forma Consolidated Financial Information" and the related notes thereto,
"Selected Historical Financial Data of Araxas" and the financial statements of
Araxas and the South Coast Companies and the related notes thereto included
elsewhere in this Prospectus.
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
The Company's Certificate of Incorporation and Bylaws and the Delaware General
Corporation Law contain provisions that may have the effect of delaying,
deferring or preventing a change in control of the Company. These provisions,
among other things, provide for a classified Board of Directors with staggered
terms, restrict the ability of stockholders to take action by written consent,
authorize the Board of Directors to set the terms of preferred stock and
provide for a supermajority vote for business combinations with related
persons. See "Description of Capital Stock."
 
NO PRIOR PUBLIC MARKET
 
Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price will be determined by negotiation between the
Company and the Underwriters and may not be indicative of the price at which
the Common Stock will trade following the completion of the Offering. See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price. The completion of the Offering provides no
assurance that an active trading market for the Common Stock will develop or,
if developed, that it will be sustained. The market price of the Common Stock
could also be subject to significant fluctuation and may be influenced by many
factors, including variations in results of operations, variations in oil and
gas prices, investor perceptions of the Company and the oil and gas industry
and general economic and other conditions.
 
DILUTION
 
Purchasers of Common Stock in the Offering will experience immediate and
substantial dilution in the net tangible book value of their stock of     per
share (assuming an initial public offering price of $    per share). See
"Dilution."

                                USE OF PROCEEDS
 
The net proceeds to the Company from the sale of the     shares of Common Stock
offered hereby to be sold by the Company are estimated to be approximately $
million ($    million if the Underwriters' over-allotment option is exercised
in full), based on an assumed initial public offering price of $    per share
and after deducting underwriting discounts and expenses of the Offering payable
by the Company. If the Underwriters exercise the over-allotment option, the
Company will receive no proceeds from the sale of shares of Common Stock by the
Selling Stockholders. The Company intends to use the net proceeds as follows:

The Company does not intend to declare or pay dividends on its Common Stock in
the foreseeable future. The Company currently intends to retain any earnings
for the future operation and development of its business, including
exploration, development and acquisition activities. In addition, the payment
of dividends by the Company is restricted by the terms of the Company's credit

                                    DILUTION
 
As of September 30, 1997, the net tangible book value of the Company was
approximately $   million, or approximately $   per share of Common Stock. Net
tangible book value per share represents the amount of the Company's tangible
book value (total book value of tangible assets less total liabilities) divided
by the total number of shares of Common Stock outstanding. After giving effect
to the receipt of the estimated net proceeds from the Offering at an assumed
initial public offering price of $   per share (after deducting underwriting
discounts and expenses of the Offering payable by the Company), the adjusted
pro forma net tangible book value of the Common Stock outstanding at September
30, 1997 would have been $   per share, representing an immediate increase in
net tangible book value of $   per share to existing stockholders and an
immediate and substantial dilution of $   per share (the difference between the
assumed initial public offering price and the net tangible book value per share
after the Offering) to new investors purchasing Common Stock at the assumed
initial public offering price. The following table illustrates such per share
dilution:

                          THE COMBINATION TRANSACTION
 
XPLOR was formed through the strategic combination in September 1997 of Araxas
and the South Coast Companies in the Combination Transaction, which was
accounted for as a purchase of the South Coast Companies by XPLOR, as successor
to Araxas. Management believes that the Combination Transaction will enhance
the Company's ability to increase its reserves, production and cash flow per
share by combining the complementary strengths of Araxas's operating expertise,
the South Coast Companies' geophysical expertise and the two companies'
portfolios of exploration prospects concentrated in the Gulf Coast region.
 
The Company was incorporated in Delaware in July 1997 to consolidate and
continue activities previously conducted by Araxas and the South Coast
Companies. In the Combination Transaction, the Company (i) acquired all of the
outstanding capital stock of Araxas, South Coast and INEXS, and all of the
outstanding limited partnership interests of SOCO, (ii) issued to the owners of
the outstanding capital stock of Araxas    shares of Common Stock and (iii)
issued to the owners of the outstanding capital stock and limited partnership
interests of the South Coast Companies    shares of Common Stock and $3.0
million principal amount of Combination Notes. The Combination Notes mature at
the closing of the Offering and will be repaid with the net proceeds therefrom.
To secure payment of the Combination Notes, the former stockholders of INEXS
(all of whom are officers of the Company) hold a lien on all of the capital
stock of INEXS.
 
Prior to the Combination Transaction, the outstanding capital stock of Araxas
was owned in part by Messrs. Rowsey and Nance and by New West, and the
outstanding capital stock and partnership interests of the South Coast Entities
were owned in part by Mr. Krenzke, Mr. Craig S. Davis and Mr. Philip V. Duggan,
and by Equitable. In addition, Stratum held an option to purchase capital stock
of Araxas. As a result of the Combination Transaction, Mr. Rowsey, Mr. Nance
and New West beneficially own     ,      and      shares of Common Stock,
respectively, Messrs. Krenzke, Davis and Duggan and Equitable beneficially own
   ,    ,     and     shares of Common Stock, respectively, and Stratum has an
option to purchase      shares of Common Stock.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
The unaudited pro forma consolidated financial information of XPLOR reflects
the Combination Transaction as a purchase of the South Coast Companies by
XPLOR, as successor to Araxas, the August 1996 acquisition of Main Pass 35 and
the April 1997 divestiture of Gulfland Industries. The unaudited pro forma
consolidated balance sheet gives effect to the Combination Transaction as
though it were consummated as of June 30, 1997 (the acquisition of Main Pass 35
and the divestiture of Gulfland Industries having been consummated prior to
such date). The unaudited pro forma consolidated statement of operations for
the year ended December 31, 1996 and the six months ended June 30, 1997 give
effect to the transactions as though they were consummated as of January 1,
1996.
 
The following unaudited pro forma information has been included as required by
the rules of the Securities Exchange Commission and is provided for comparison
purposes only. The unaudited pro forma information is based upon the historical
consolidated financial statements of Araxas and the South Coast Companies and
the statements of revenues and direct operating expenses of Main Pass 35, and
should be read in conjunction with such financial statements and the related
notes thereto included elsewhere herein. The unaudited pro forma information
does not include the impact of the debt refinancing that occurred coincident
with the Combination Transaction. A charge of approximately $3.8 million to
reflect these items will be included in the unaudited interim financial
statements of the Company for the nine months ended September 30, 1997. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "--Hedging."
 
The pro forma information is based on assumptions and includes adjustments as
explained in the notes to the unaudited pro forma consolidated financial
statements, and the actual recording of the transactions could differ once fair
value estimates and actual costs are finalized. The unaudited pro forma
information does not purport to be indicative of the Company's financial
condition or results of operations had such transactions occurred as of the
date or prior to the periods presented or to project the Company's future
financial condition or results of operations.
 
The per share data and weighted average common shares and dilutive common
equivalent shares outstanding included in the pro forma information do not give
effect to the       -for-       split of the Common Stock to be effected prior
to the consummation of the Offering.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
XPLOR is an independent energy company engaged in the exploration for and
development of oil and gas reserves, primarily in the Louisiana and Texas Gulf
Coast region. The Company focuses on growth through drilling, combining
sophisticated technologies such as 3-D seismic data and interactive computer
analytical techniques with an experienced technical staff and management. XPLOR
applies a disciplined exploration methodology consisting of traditional
subsurface geology followed by acquisition and analysis of specifically
targeted 3-D seismic data, integrated with sound engineering and economic
principles. This methodology is designed to use 3-D seismic data cost-
effectively to confirm rather than to generate prospects.
 
XPLOR was formed through the strategic combination of Araxas and the South
Coast Companies in the Combination Transaction. Management believes that the
Combination Transaction will enhance the Company's ability to increase its
reserves, production and cash flow per share by combining the complementary
strengths of Araxas's operating expertise, the South Coast Companies'
geophysical expertise and the two companies' portfolios of exploration
prospects concentrated in the Gulf Coast region. See "The Combination
Transaction."
 
The Company has grown through exploration, development opportunities and the
acquisition of properties with existing production. In 1995, the Company
acquired substantial working interests in the Adams-Baggett field in Crockett
County, Texas, and in 1996 acquired substantial working interests in Main Pass
35 in the shallow state waters of Louisiana and High Island 30L in the state
waters of Texas. These acquisitions were funded through borrowings and cash
flow from operations.
 
Over time, the Company has shifted its focus from being primarily a generator
and seller of prospects to that of a working interest owner and operator. In
connection with the Company's acquisition of Main Pass 35, the Company also
acquired Gulfland Industries, a contract operator of offshore platforms. The
Company divested Gulfland Industries in April 1997.
 
The Company uses the full-cost method of accounting for its oil and gas
properties. Under this method, all acquisition, exploration and development
costs, including any general and administrative costs that are directly
attributable to the Company's acquisition, exploration and development
activities, are capitalized as incurred. The Company records depletion of
capitalized costs and future development costs using the unit-of-production
method. To the extent that such capitalized costs (net of depreciation,
depletion and amortization and related deferred taxes) exceed the present value
(using a 10% discount rate) of estimated future net after-tax cash flows from
proved oil and gas reserves, such excess costs are recorded as additional
depletion. The Company has not been required to make any such write-downs. Once
incurred, a write-down of oil and gas properties is not reversible at a later
date.
 
LIQUIDITY AND CAPITAL RESOURCES
 
The Company's primary sources of capital have been borrowings, equity capital
from private sources and funds generated by operations. The Company's primary
capital requirements are drilling expenditures and 3-D seismic and land
acquisition costs. On a pro forma basis, as of June 30, 1997, the Company had a
working capital deficit of $2.2 million and indebtedness as a percentage of
total capitalization of 61%. The Company intends to use the net proceeds from
the Offering to repay indebtedness and for capital expenditures, including
funding its exploration and development activities.
 
Financing Transactions
 
The Company's borrowings were formerly made under a $42.5 million credit
facility with Stratum. In September 1997, the Company entered into the Bridge
Loan with Credit Lyonnais and repaid in full and terminated its borrowing
arrangements with Stratum. The Bridge Loan provides for availability of up to
$35.0 million, of which
 
                                       28
<PAGE>
 
$30.8 million was outstanding at September 30, 1997. Borrowings under the
Bridge Loan bear interest at a fluctuating rate (10% per annum at September 30,
1997) based upon the Credit Lyonnais base rate or LIBOR, and will mature upon
the closing of the Offering.
 
Upon the closing of the Offering, the Bridge Loan will convert into a revolving
credit facility (the "Credit Facility"), which will provide for a maximum loan
amount of $100 million, subject to borrowing base limitations. The initial
borrowing base will provide for availability of up to $20 million, none of
which is expected to be outstanding immediately following the Offering. The
principal amount outstanding under the Credit Facility will be due and payable
upon maturity in September 2000. Borrowings under the Credit Facility will bear
interest, at the Company's option, at a fluctuating rate based on LIBOR plus 1%
to 1.5% per annum or based on the Credit Lyonnais base rate. The Company's
obligations under the agreement governing both the Bridge Loan and the Credit
Facility (the "Credit Agreement") are secured by all of its oil and gas
properties and by the capital stock of its subsidiaries. The Company's
subsidiaries also provide guarantees under the Credit Agreement.
 
Under the Credit Facility, Credit Lyonnais will make semi-annual borrowing base
determinations, in its sole discretion, based upon the proved oil and gas
properties of the Company. In addition, Credit Lyonnais may redetermine the
borrowing base at any time after December 31, 1997. The Company may also
request borrowing base redeterminations at the Company's cost in addition to
the required semi-annual reviews.
 
The Company is subject to certain covenants under the terms of the Credit
Agreement and must meet certain financial tests, including those relating to
interest coverage, current ratio and tangible net worth. The Company believes
that it is currently in compliance with such covenants. The Credit Agreement
also places restrictions on, among other things, incurring additional
indebtedness and liens, changing the nature of the Company's business, selling
assets and paying dividends.
 
In the Combination Transaction, the Company issued to former stockholders of
INEXS an aggregate of $3.0 million principal amount of Combination Notes
maturing on the closing of the Offering. The Company has also issued to a
former employee a $1.0 million note maturing on the closing of the Offering.
The Company intends to use a portion of the proceeds from the Offering to repay
in full the Combination Notes and the $1.0 million note. See "Use of Proceeds."
 
To provide additional working capital for the Company prior to the consummation
of the Bridge Loan, the Company borrowed $5.0 million from Equitable in July
1997. The Equitable loan bears interest at the rate of 9% per annum and will
mature on July 31, 1998. The Company intends to use a portion of the net
proceeds from the Offering to repay this loan in full. See "Use of Proceeds."
 
In connection with the termination of employment of a former employee, the
Company purchased FO&G, which owned small working interests in certain of the
Company's properties. The Company purchased FO&G for $750,000 in cash and a
$2.2 million promissory note that bears interest at the rate of 5.8% per annum
and will mature upon the closing of the Offering. The Company intends to use a
portion of the net proceeds from the Offering to repay this note in full. See
"Use of Proceeds" and "Certain Transactions."
 
Capital Expenditures
 
The Company has budgeted capital expenditures for the last three months of 1997
and for 1998 of approximately $41.0 million. The capital expenditure budget
includes the planned drilling of 68 gross (17.0 net) planned wells, the
acquisition of additional 3-D seismic data and further additions to and
upgrades of seismic interpretation hardware and software. The actual number of
wells drilled in this period may differ significantly from these estimates. See
"Business--Significant Properties and Project Areas."
 
As a result of the Company's active drilling and 3-D seismic acquisition
programs, the Company has experienced and expects to continue to experience
substantial capital requirements. While the Company believes that the net
proceeds from the Offering, cash flow from operations and borrowings under the
Credit Facility should allow the Company to finance its operations through 1998
based on current conditions, additional financing may be required in the future
to fund the Company's drilling and 3-D seismic acquisition programs. In the
event additional financing is not available, the Company may be required to
curtail these activities.

RESULTS OF OPERATIONS OF XPLOR
 
The Combination Transaction was consummated in September 1997 and accounted for
as a purchase of the South Coast Companies by XPLOR, as successor to Araxas. As
a result of the Combination Transaction, the Company's results of operations
reflect a substantial expansion in the size of its operations compared to the
individual historical results of operations of Araxas and the South Coast
Companies. To facilitate an understanding of the changes in results of
operations of the Company's business, the discussion below is based upon a
comparison of the unaudited pro forma operating information for the years ended
December 31, 1995 and 1996 and the six months ended June 30, 1996 and 1997,
prepared assuming that the Combination Transaction, the August 1996 acquisition
of Main Pass 35 and the April 1997 divestiture of Gulfland Industries had been
consummated on January 1, 1995 and January 1, 1996, as appropriate.

Pro Forma Six Months Ended June 30, 1997 Compared to Pro Forma Six Months Ended
June 30, 1996
 
Revenues. Oil and gas revenues increased $0.3 million, or 6%, from $4.6 million
in the first six months of 1996 to $4.9 million in the first six months of
1997. Total production volumes increased 20% from 1,509 MMcfe in the first six
months of 1996 to 1,817 MMcfe in the first six months of 1997. Production
volumes for oil and condensate increased from 145 MBbls in the first six months
of 1996 to 164 MBbls in the first six months of 1997. The majority of the
increase was attributable to the High Island 30L field, which was acquired in
the latter part of 1996. Production volumes for gas increased 30% from 641 MMcf
in the first six months of 1996 to 834 MMcf in the first six months of 1997.
This increase was primarily attributable to three new wells. The increase in
revenues from higher production was partially offset by declines of 13% and 9%
in the prices received for oil and gas, respectively.

As a result of hedging activities, the Company realized an average oil price of
$17.85 per Bbl and an average gas price of $2.31 per Mcf for the six months
ended June 30, 1997, compared to average prices of $21.35 per Bbl and $2.51 per
Mcf, respectively, that otherwise would have been received. These hedging
activities decreased oil and gas revenues by approximately $0.7 million in the
six months ended June 30, 1997. The hedges, which were required by the terms of
the Stratum debt agreement, were entered into commencing in May 1996 and had no
significant effect on the six months ended June 30, 1996. During September
1997, the Company closed all of its outstanding hedging arrangements. See "--
Hedging."
 
Consulting revenues increased $0.4 million, or 66%, from $0.6 million in the
first six months of 1996 to $1.0 million in the first six months of 1997. The
increase was primarily due to a greater level of activity with more geophysical
consultants working for the Company, resulting in higher billable hours, as
well as higher rates.
 
Expenses. Lease operating expenses decreased from $2.0 million in the first six
months of 1996 to $1.1 million in the first six months of 1997, a decrease of
$0.9 million, or 41%, primarily as a result of unusual costs incurred in the
operation of Main Pass 35 prior to its acquisition. The decrease in production
taxes and gathering fees from the first six months of 1996 to the first six
months of 1997 was insignificant.
 
Consulting and workstation fees increased from $0.2 million in the first six
months of 1996 to $0.3 million in the first six months of 1997. The increase
was primarily due to a greater number of consultants being employed.
 
Depreciation, depletion and amortization ("DD&A") was $1.5 million in the first
six months of 1996, compared to $1.9 million in the first six months of 1997,
an increase of $0.4 million, or 30%, as a result of higher volumes. On a per
Mcfe basis, the depletion rate was constant at $0.88.
 
General and administrative expenses increased 50% from $1.2 million in the
first half of 1996 to $1.8 million in the first half of 1997. The increase was
primarily due to an increase in the number of employees and consultants, an
increase in the cost of independent engineering services and an increase in
office rent.
 
Interest expense increased from $1.4 million in the first six months of 1996 to
$2.0 million in the first six months of 1997. The increase was primarily
attributable to the higher debt outstanding during the first half of 1997
compared to the first half of 1996. The incremental debt was incurred to fund
capital expenditures.
 
Income tax benefit was $0.2 million for the six months ended June 30, 1997
compared to $0.4 million for the same period in 1996.
 
Net Loss. Net loss was $1.1 million in the first half of 1996 as compared to a
net loss of $1.7 million in the first half of 1997 as a result of the factors
described above.
 
Pro Forma Year Ended December 31, 1996 Compared to Pro Forma Year Ended
December 31, 1995
 
Revenues. Oil and gas revenues increased $3.7 million, or 61%, from $6.1
million in 1995 to $9.8 million in 1996. Total production volumes increased 35%
from 2,402 MMcfe in 1995 to 3,239 MMcfe in 1996. Production volumes for oil and
condensate increased from 272 MBbls in 1995 to 311 MBbls in 1996. This increase
was attributable to one new well brought on in 1996 and the acquisition of the
High Island 30L field. Production volumes for gas increased from 769 MMcf in
1995 to 1,371 MMcf in 1996. This increase was primarily attributable to four
wells brought on in 1996 and late 1995. The increase in total net production in
1996 increased revenues by $1.7 million, or 46%. In addition, the Company
experienced a 17% increase in oil prices and a 45% increase in gas prices
received in 1996 compared to 1995.
 
As a result of hedging activities, the Company realized an average oil price of
$20.79 per Bbl and an average gas price of $2.41 per Mcf for the year ended
December 31, 1996, compared to average prices of $21.99 per Bbl and $2.58 per
Mcf that otherwise would have been received. These hedging activities decreased
oil and
 
                                       31
<PAGE>
 
gas revenues by approximately $0.6 million in 1996. The hedges were entered
into in 1996 and were required by the terms of the Stratum debt agreement.
 
Consulting revenues increased $0.5 million, or 59%, from $0.9 million in 1995
to approximately $1.4 million in 1996. The increase was primarily due to a
greater level of activity with more geophysical consultants working for the
Company, resulting in higher billable hours, as well as higher rates.
 
Expenses. Lease operating expenses increased from $3.3 million in 1995 to $3.9
million in 1996, an increase of $0.6 million, or 17%, primarily as a result of
new wells that were brought on in late 1995 and in 1996, as well as the High
Island 30L field acquisition. Likewise, production taxes and gathering fees
increased from $0.7 million in 1995 to $1.0 million in 1996, an increase of
$0.3 million, or 40%, due to greater volumes and resulting revenue increases.
 
Consulting and workstation fees increased $0.3 million, from $0.3 million in
1995 to $0.6 million in 1996. The increase was primarily due to a greater
number of consultants being employed.
 
DD&A was $2.4 million in 1995, compared to $3.3 million in 1996, an increase of
$0.9 million, or 40%, based on an assumed depletion rate of $0.88 per Mcfe.
 
General and administrative expenses decreased from $3.2 million in 1995 to $2.6
million in 1996, a decrease of $0.6 million, or 18%. The decrease was primarily
attributable to an item of compensation expense of approximately $1.3 million
recorded in 1995 relating to stock options granted that year. This decrease was
partially offset by the increase associated with a larger staff and more
activity as the Company underwent significant growth.
 
Interest expense increased by $0.8 million, or 33%, from $2.6 million in 1995
to $3.4 million in 1996. The increase was primarily attributable to the higher
debt outstanding during 1996 compared to 1995. The incremental debt was
incurred to fund capital expenditures.
 
Interest income decreased $0.2 million from $0.5 million in 1995 to $0.3
million in 1996. The decrease was primarily due to decreasing cash balances.
 
Other expense increased by $0.6 million from $0.1 million in 1995 to $0.7
million in 1996, primarily as a result of an unrealized loss on securities.
 
Income tax benefit decreased from $1.9 million in 1995 to $0.6 million in 1996,
a decrease of $1.3 million, or 67%, primarily as a result of the complete use
of deferred tax liabilities as an offset to deferred tax assets.
 
Net Loss. Net loss was $3.1 million in 1995, compared to $3.4 million in 1996,
as a result of the factors described above.
 
RESULTS OF OPERATIONS OF ARAXAS
 
Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
Revenues. Oil and gas revenues increased $2.6 million from $1.8 million in the
first six months of 1996 to $4.4 million in the first six months of 1997. Total
production volumes increased 138% from 712 MMcfe in the first six months of
1996 to 1,695 MMcfe in the first six months of 1997. Production volumes for oil
and condensate increased from 23 MBbls in the first six months of 1996 to 151
MBbls in the first six months of 1997. This increase was attributable primarily
to production both from Main Pass 35 and High Island 30L, which were acquired
in the latter part of 1996 and accounted for 119 MBbls of the increase.
Production volumes for gas increased 38% from 571 MMcf in the first six months
of 1996 to 790 MMcf in the first six months of 1997. This increase was
primarily attributable to two new wells. The increase in volumes of oil and gas
accounted for an increase in revenues of approximately $3.0 million, offset by
declines of 11% and 5% in the prices received for oil and gas, respectively.
 
                                       32

As a result of hedging activities, Araxas realized an average oil price of
$17.67 per Bbl and an average gas price of $2.26 per Mcf for the six months
ended June 30, 1997, compared to average prices of $21.46 per Bbl and $2.47 per
Mcf that otherwise would have been received. These hedging activities decreased
oil and gas revenues by approximately $0.7 million in the six months ended June
30, 1997. The hedges, which were required by the terms of Araxas's debt
agreement with Stratum, were entered into commencing in May 1996.
 
Revenues from offshore services (conducted by Gulfland Industries) were $1.6
million in the six months ended June 30, 1997, while the cost of offshore
services was $1.7 million in the same period. Araxas did not acquire this
business until August 1996, and accordingly no amounts were recorded in the six
months ended June 30, 1996. Araxas disposed of this business in April 1997.
 
Expenses. Lease operating expenses increased from $0.2 million in the first six
months of 1996 to $1.1 million in the first six months of 1997, an increase of
$0.9 million, primarily as a result of the greater production due to the Main
Pass 35 and High Island 30L property acquisitions that were completed in 1996,
as well as the new wells that were brought on production during the latter part
of 1996 and in 1997 in other fields. In addition, lease operating expenses per
Mcfe were relatively higher on Main Pass 35 as a result of the offshore
location, the age of the platform and water injection operations. Production
taxes and gathering fees increased from $0.1 million in the first six months of
1996 to $0.4 million in the first six months of 1997 due to greater production
volumes and resulting revenue increases.
 
DD&A was $0.7 million in the first six months of 1996, compared to $1.3 million
in the first six months of 1997, an increase of $0.6 million, or 77%, as a
result of higher production volumes. On a per Mcfe basis, the depletion rate
decreased 17% from $0.78 used for the first half of 1996 to $0.65 in the first
half of 1997.
 
General and administrative expenses increased from $0.8 million in the first
half of 1996 to $1.0 million in the first half of 1997, an increase of $0.2
million, or 26%. The increase was primarily due to a larger number of employees
and consultants, as well as increased independent engineering services.
 
Interest expense increased $1.4 million, from $0.4 million in the first six
months of 1996 to $1.8 million in the first half of 1997. The increase was
primarily attributable to the higher debt outstanding during the first half of
1997 compared to the first half of 1996 and the higher rate associated with the
debt outstanding during the entire period in 1997. The debt outstanding during
the first half of 1997 was principally incurred in April 1996 to refinance debt
and to acquire assets requiring a cash outlay of approximately $10.3 million.
 
Income tax benefit was insignificant for both the six months ended June 30,
1996 and June 30, 1997, despite pre-tax losses of $0.5 million and $1.4
million, respectively, primarily as a result of net operating losses
attributable to tax losses not expected to be realized as a tax benefit to
Araxas.
 
Net Loss. Net loss was $1.4 million in the first half of 1997, compared to $0.4
million in the first half of 1996, as a result of the factors described above.
 
Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
Revenues. Oil and gas revenues increased $4.6 million, from $1.4 million in
1995 to $6.0 million in 1996. Total production volumes increased 202% from 721
MMcfe in 1995 to 2,179 MMcfe in 1996. Production volumes for oil and condensate
increased from 44 MBbls in 1995 to 154 MBbls in 1996. This increase was
attributable primarily to production from Main Pass 35 and High Island 30L,
which were acquired in 1996 and accounted for 90 MBbls of the increase, and
from new wells brought on during 1996. Production volumes for gas increased
from 460 MMcf in 1995 to 1,256 MMcf in 1996. This increase was primarily
attributable to four new wells brought on in 1996 or late 1995. The increase in
total net production in 1996 compared to 1995 increased revenues by $2.9
million. In addition, Araxas experienced a 29% increase in oil prices and a 55%
increase in gas prices received in 1996 as compared to 1995.

As a result of hedging activities, Araxas realized an average oil price of
$20.68 per Bbl and an average gas price of $2.28 per Mcf for the year ended
December 31, 1996, compared to average prices of $23.12 per Bbl and $2.46 per
Mcf, respectively, that otherwise would have been received. These hedging
activities decreased oil and gas revenues by approximately $0.6 million in
1996. The hedges were entered into in 1996 and were required by the terms of
Araxas's debt agreement with Stratum.
 
Revenues from offshore services were $1.7 million in 1996. Araxas entered this
business with the purchase of Gulfland Industries, which was acquired in
connection with Main Pass 35, in August 1996. Cost of offshore services was
$2.2 million in 1996. Araxas disposed of this business in April 1997.
 
Expenses. Lease operating expenses increased from $0.3 million in 1995 to $1.6
million in 1996, an increase of $1.3 million, primarily as a result of the
greater production due to the Main Pass 35 and High Island 30L acquisitions
that were completed in 1996 and the more costly operations in Main Pass 35, as
well as new wells that were brought on production during 1996 in other fields.
Likewise, production taxes and gathering fees increased from $0.1 million in
1995 to $0.6 million in 1996, an increase of $0.5 million, resulting from
greater production volumes and resulting revenue increases.
 
DD&A was $0.7 million in 1995, compared to $1.7 million in 1996, an increase of
$1.0 million. On a per Mcfe basis, the depletion rate decreased by $0.13 from
$0.78 in 1995 to $0.65 in 1996.
 
General and administrative expenses decreased from $2.2 million in 1995 to $1.5
million in 1996, a decrease of $0.7 million, or 31%. The decrease was primarily
attributable to an item of compensation expense of approximately $1.3 million
recorded in 1995 relating to stock options granted that year. This decrease was
partially offset by the increase associated with a larger staff and more
activity as Araxas experienced significant growth.
 
Interest expense increased $1.6 million, from $0.5 million in 1995 to $2.1
million in 1996. The increase was primarily attributable to the higher debt
outstanding during 1996 compared to 1995 and the higher rate associated with
the debt outstanding in 1996. The debt incurred in 1996 was incurred to
refinance debt and to acquire assets in April 1996 requiring a cash outlay of
approximately $10.3 million.
 
Other expense increased from $0.1 million in 1995 to $0.7 million in 1996,
primarily as a result of an unrealized loss on securities.
 
Income tax benefit decreased from $0.9 million in 1995 to $36,000 in 1996,
primarily as a result of net operating losses attributable to tax losses not
expected to be realized as a tax benefit to Araxas.
 
Net Loss. Net loss was $1.6 million in 1995, compared to $2.5 million in 1996,
as a result of the factors described above.
 
Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
Revenues. Oil and gas revenues increased $1.2 million from $0.2 million in 1994
to $1.4 million in 1995. Total production volumes were 721 MMcfe in 1995.
Production volumes for oil and condensate increased to 44 MBbls in 1995, and
production volumes for gas increased to 460 MMcf in 1995. Production volumes
for both oil and gas were insignificant in 1994. The increase in production
volumes was attributable primarily to production from the Adams-Baggett field
and another property, both acquired in 1995, and from new wells brought on
during that year. The increase in total net production in 1995 compared to 1994
increased revenues by $1.2 million.
 
Expenses. Lease operating expenses increased from $245,000 in 1994 to $296,000
in 1995, an increase of 21%, primarily as a result of the greater production
due to property acquisitions that were completed in 1995, and the new wells
that were brought on production during that year in other fields. Likewise,
production taxes and gathering fees increased from $12,000 in 1994 to $99,000
in 1995 due to greater volumes and resulting revenue increases.

DD&A was $0.1 million in 1994, compared to $0.7 million in 1995. On a per Mcfe
basis, the depletion rate decreased from $0.79 in 1994 to $0.78 in 1995.
 
General and administrative expenses increased from $0.9 million in 1994 to $2.2
million in 1995. The increase was primarily attributable to an item of
compensation expense of approximately $1.3 million recorded in 1995 relating to
stock options granted that year.
 
Gains on sales of oil and gas properties were $1.3 million in 1994. During
1994, Araxas sold interests in a number of leases, each of which were
significant to Araxas, thus requiring the recognition of gain or loss on the
transactions, rather than crediting the full cost pool. In 1995, Araxas began
to shift its focus from being primarily a generator and seller of prospects to
that of a participating working interest owner, attempting to retain greater
interests.
 
Interest expense increased from $0.1 million in 1994 to $0.5 million in 1995.
The increase was primarily attributable to the higher debt outstanding during
1995 compared to 1994. The debt was incurred in connection with the purchase of
properties in 1995.
 
Income tax benefit was $0.9 million in 1995 as compared to an expense of
$26,000 in 1994, primarily as a result of the use of deferred tax liabilities
as an offset to deferred tax assets.
 
Net Loss. Net loss was $1.6 million in 1995, compared to net income of $40,000
in 1994, as a result of the factors described above.
 
HEDGING
 
The Company's former debt agreement with Stratum required the Company to put
into place significant long-term arrangements in an effort to reduce the
effects of short-term fluctuations in the price of oil and gas. Such
arrangements were required at the closing of such financing in April 1996 and
at the times of additional drawdowns thereunder. The Company repaid and
terminated the Stratum debt agreement in September 1997, and the Credit
Agreement does not require the Company to maintain hedges. During September
1997, the Company closed all its outstanding hedging arrangements, resulting in
losses of $2.8 million. The Company currently does not intend to hedge more
than one-third of its production, but may reevaluate its hedging policy from
time to time. The Company may also close out any portion of hedges that may
exist from time to time as determined to be appropriate by management. During
the year ended December 31, 1996, the Company received a fixed price and paid
the NYMEX price with respect to 575 MMBtus of gas and 60 MBbls of oil under
commodity price arrangements, realizing losses of $598,000. During the first
six months of 1997, the Company received a fixed price and paid the NYMEX price
with respect to 338 MMBtus of gas and 177 MBbls of oil under commodity price
arrangements, realizing losses of $739,000. See "Business--Marketing."
 
EFFECTS OF INFLATION AND CHANGES IN PRICE
 
The Company's results of operations and cash flows are affected by changing oil
and gas prices. Inflation has had a minimal effect on the Company. See "Risk
Factors--Volatility of Oil and Gas Prices."
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128 regarding earnings
per share. SFAS No. 128 replaces the presentation of primary earnings per share
("EPS") with the presentation of basic EPS, which excludes dilution and is
computed by dividing income available to common stockholders by the weighted-
average number of shares of common stock outstanding for the period. SFAS No.
128 also requires dual presentation of basic EPS and diluted EPS on the face of
the income statement and requires a reconciliation of the numerators and
denominators of basic EPS and diluted EPS. The Company will adopt SFAS No. 128
for the quarter ended December 31, 1997.
 
 
                                       35
<PAGE>
 
In June 1997, FASB issued SFAS No. 130 regarding reporting comprehensive
income, which establishes standards for reporting and display of comprehensive
income and its components. The components of comprehensive income refer to
revenues, expenses, gains and losses that are excluded from net income under
current accounting standards, including foreign currency translation items,
minimum pension liability adjustments and unrealized gains and losses on
certain investments in debt and equity securities. SFAS No. 130 requires that
all items recognized under accounting standards as components of comprehensive
income be reported in a financial statement displayed in equal prominence with
the other financial statements; the total of other comprehensive income for a
period is required to be transferred to a component of equity that is
separately displayed in a statement of financial condition at the end of an
accounting period. SFAS No. 130 is effective for both interim and annual
periods beginning after December 15, 1997. Reclassification of financial
statements for earlier periods provided for comparative purposes is required.
The Company will adopt SFAS No. 130 for the fiscal year ending December 31,
1998.
 
In June 1997, FASB issued SFAS No. 131 regarding disclosures about segments of
an enterprise and related information. SFAS No. 131 establishes standards for
reporting information about operating segments in annual financial statements
and requires the reporting of selected information about operating segments in
interim financial reports issued to stockholders. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. SFAS No. 131 is effective for periods beginning after December 15,
1997. The Company will adopt SFAS No. 131 for the fiscal year ending December
31, 1998.
 
The Company believes that adoption of these financial accounting standards will
not have a material effect on its financial condition or results of operations.

GENERAL
 
XPLOR is an independent energy company engaged in the exploration for and
development of oil and gas reserves, primarily in the Louisiana and Texas Gulf
Coast region. The Company focuses on growth through drilling, combining
sophisticated technologies such as 3-D seismic data and interactive computer
analytical techniques with an experienced technical staff and management. XPLOR
applies a disciplined exploration methodology consisting of traditional
subsurface geology followed by acquisition and analysis of specifically
targeted 3-D seismic data, integrated with sound engineering and economic
principles. This methodology is designed to use 3-D seismic data cost-
effectively to confirm rather than to generate prospects. See "--Exploration
Methodology."
 
XPLOR was formed through the strategic combination of Araxas and the South
Coast Companies in the Combination Transaction. Management believes that the
Combination Transaction will enhance the Company's ability to increase its
reserves, production and cash flow per share by combining the complementary
strengths of Araxas's operating expertise, the South Coast Companies'
geophysical expertise and the two companies' portfolios of exploration
prospects concentrated in the Gulf Coast region. See "The Combination
Transaction."
 
Between December 31, 1994 and September 30, 1997, the Company increased its net
proved reserves from approximately 8 Bcfe to approximately 58 Bcfe. Average net
production increased from 280 Mcfe per day for the year ended December 31, 1994
to approximately 9,500 Mcfe per day for the nine months ended September 30,
1997.
 
Drilling new wells and interpreting 3-D seismic and other data over existing
fields have together generated approximately 60% of the increase in the
Company's estimated proved reserves from December 31, 1994 to September 30,
1997. The Company drilled 48 gross wells during that time, consisting of 29
exploratory wells, of which 15 were commercially productive, and 19 development
wells, of which 17 of which were commercially productive. The Company also has
added reserves through acquisitions, which accounted for the balance of the
reserve increase from December 31, 1994 to September 30, 1997. During this
period, the Company completed major acquisitions of substantial working
interests in the Adams-Baggett field in Crockett County, Texas, and Main Pass
35 in the shallow state waters of Louisiana. The Company's reserve growth has
been achieved at an average finding cost of $0.72 per Mcfe and an average
acquisition cost of $0.70 per Mcfe. Although the Company expects that its
future reserve and production growth will result primarily from its drilling
program, the Company will consider acquisitions with significant growth
potential.
 
The Company has acquired over 700 square miles of 3-D seismic data and has
leased or optioned acreage in 17 project areas. Within these project areas,
XPLOR currently has 98 exploration and development prospects scheduled to be
drilled over the next two to three years. Prior to the Offering, capital
constraints limited the Company's ability to drill its prospect inventory. At
the closing of this Offering, however, the Company expects to have available
for its drilling program $   million in net proceeds from the Offering and an
additional $20.0 million available for borrowing under the Credit Facility.
XPLOR has budgeted total capital expenditures of approximately $41.0 million
through the end of 1998, which includes funds for drilling approximately 80% of
its currently identified exploration and development prospects. The Company
believes that its current prospect inventory includes both moderate potential,
lower risk prospects and higher potential, higher risk prospects that, if
successful, may result in significant increases in proved reserves.
 
The address of the Company's principal executive offices is 10200 Grogans Mill
Road, Suite 500, The Woodlands, Texas 77380, and its telephone number is (281)
364-3700.

STRENGTHS
 
XPLOR believes it has the following strengths that are integral to its overall
growth strategy:
 
Experienced Technical Team
 
The Company has assembled a technical team that has extensive experience in
applying sophisticated exploration techniques and that it believes has the
capacity to adapt to rapidly changing technological demands. The Company
employs 11 geoscientists, consisting of four geologists and seven
geophysicists, all of whom have 15 to 25 years of experience in exploring for
oil and gas. The Company also has an experienced group of engineers who
participate in the evaluation of the Company's potential projects and also
manage the Company's drilling and production operations.
 
Advanced Technology
 
The Company's experienced technical team applies advanced technology in oil and
gas exploration and has access to the latest enhancements in such technologies.
The Company provides its technical team with a sophisticated in-house computer-
based work environment, which enables the team to evaluate and integrate data
efficiently. XPLOR has a networked environment consisting of 10 workstations
running the latest 3-D design, modeling, interpretation, mapping, processing
and visualization software applications.
 
INEXS, the Company's geophysical consulting subsidiary, is an integral part of
the Company's technology base and gives the Company access to the latest
advances in geoscientific technologies. INEXS has specialized in 3-D seismic
interpretation and project management services since 1990 and has interpreted
over 180 3-D seismic surveys for over 133 companies, including major
integrated, foreign national and independent oil and gas companies. INEXS's
clients have drilled more than 100 wells based on INEXS's interpretation work,
over 70% of which the Company believes have been completed as commercial
producers. As a result of this high level of activity, INEXS has formed working
relationships with a number of technology providers. Consequently, INEXS has
participated in the design and testing of new applications, providing access to
emerging technologies prior to their availability for general use.
 
Existing Prospect Inventory and Proved Reserves
 
XPLOR has an existing inventory of 98 exploration and development prospects
scheduled to be drilled within the next two to three years. The Company has
leased or optioned acreage for all 98 prospects. Of these prospects, 70 are
exploratory and 28 are development. The Company also has identified additional
exploratory prospects in various stages of evaluation, planning and
implementation. The Company had total proved reserves of approximately 58 Bcfe
at September 30, 1997, of which approximately 29 Bcfe were proved developed.
For the nine months ended September 30, 1997, net production averaged
approximately 9,500 Mcfe per day.
 
Experienced Management
 
XPLOR's executive management has experience in both traditional exploratory and
operational areas and in the application of the latest technological advances.
The Company's executive management has an average of over 20 years of industry
experience in engineering, geology, geophysics and finance, primarily with
major integrated and large independent oil and gas companies. The Company has
established both short-term and long-term incentive plans for management
designed to align compensation with the interests of stockholders. See
"Management."
 
BUSINESS STRATEGY
 
XPLOR intends to increase its oil and gas reserves, production and cash flow
per share by emphasizing the following:
 
Growth Through Exploration and Development
 
The Company believes that its future growth in reserves, production and cash
flow per share will result principally from a combination of exploratory and
development drilling on the Company's inventory of prospects. In addition to
its 98 exploration and development prospects scheduled to be drilled over the
next two to three years, the
 
                                       38
<PAGE>
 
Company has identified additional exploratory prospects in various phases of
evaluation, planning and implementation. The Company follows a disciplined
methodology for the evaluation of its prospects. See "--Exploration
Methodology."
 
Prospect Generation
 
XPLOR seeks to generate internally the majority of the prospects in which it
participates. This focus on internal prospect generation enables the Company to
control the entire process, from idea formulation to management of prospective
risk and drilling decisions. The Company focuses on defining prospects that
have multiple objectives based on subsurface geology before acquiring 3-D
seismic data. The Company's inventory of prospects has also enabled the Company
to trade for additional desirable prospects held by other oil and gas
companies. In addition, third-party evaluations performed by INEXS provide the
Company with opportunities to participate in exploratory prospects with
industry partners. XPLOR may also pursue acquisition opportunities with
significant growth potential.
 
Balanced Drilling Program
 
The Company engages in an active drilling program and attempts to maintain a
balanced portfolio of exploratory and development prospects. The Company's
exploratory prospect portfolio consists of both moderate potential, lower risk
prospects and higher potential, higher risk prospects that, if successful, may
result in significant increases in proved reserves. The Company considers
balancing the relationship between risk and reward in its exploration program
an important component of its business strategy. See "--Exploration
Methodology."
 
Geographic Focus
 
XPLOR's operating activities are focused onshore and in state waters along the
Gulf Coast, primarily in Louisiana and Texas, where the Company has substantial
technical experience and expertise. Given the region's prolific production
history, the existing infrastructure and the opportunities that have been
created by advances in seismic and drilling technology, the Company believes
that the Gulf Coast represents one of the most attractive exploration regions
in North America. The Company has access to an extensive technical database of
well logs, production information and speculative seismic data for the Gulf
Coast region, and has assembled a technical staff with substantial experience
and expertise in the area. From January 1, 1994 to September 30, 1997, the
Company drilled 42 wells along the Gulf Coast and acquired a database of
geological and engineering data and approximately 400 square miles of 3-D
seismic data in the region.
 
EXPLORATION METHODOLOGY
 
The Company follows a disciplined methodology for the evaluation of exploratory
and development prospects. The methodology comprises four phases: (i)
identification of prospects in prolific geological trends with a high density
of potential reservoirs and traps; (ii) data acquisition and quality control;
(iii) data integration and interdisciplinary review; and (iv) final decision-
making based upon a thorough analysis of economic and technical information.
 
Prospect Identification
 
The Company focuses on the identification of prospects primarily in the Gulf
Coast region, where its technical staff has substantial experience and
expertise. Once a prospective area has been identified, the Company undertakes
a thorough analysis of pre-existing technical data prior to committing to major
capital expenditures for acreage and 3-D seismic data. The potential prospects
are quantified and compared to nearby fields to determine reserve and economic
potential. To qualify for a 3-D seismic program, the prospective area generally
should meet the following criteria: (i) high prospect density, with numerous
potential reservoirs and traps within a narrowly defined project area; (ii)
attractive economics for finding and developing potential reserves; and (iii)
sufficient unleased acreage or acreage that can be acquired through
negotiation. The Company subjects prospects meeting these criteria to a
preliminary economic analysis, which includes estimates of costs associated
with acreage acquisition, 3-D seismic acquisition, drilling and development,
and estimates of the probability of success. Although the Company's methodology
focuses on its 3-D seismic acquisition program, the Company may also identify
prospects based on its use of other technologies.
 
                                       39
<PAGE>
 
Data Acquisition and Quality Control
 
Once the Company has selected a project area for a 3-D seismic evaluation, the
Company's primary goal is to acquire a complete technical database and high-
quality 3-D seismic data to facilitate the detailed evaluation of prospects and
delineation of targets for exploration drilling. The Company's technical team
designs the 3-D seismic survey to image the objectives properly while taking
into consideration acquisition constraints due to surface conditions and
acreage restrictions. The Company believes that optimal results can be obtained
only through a thorough quality control effort by experienced personnel,
including analysis of proper design, selection of appropriate acquisition
equipment and techniques, field testing of acquisition parameters and selection
of appropriate processing algorithms and parameters.
 
Integration and Interdisciplinary Approach
 
The Company seeks to define accurately its prospects and reserve potential by
incorporating 3-D seismic data, well data, geological interpretations, other
geophysical data and analyses, petrophysical data and reservoir data. The
Company integrates the prospect information with drilling data, pressure
information, data relative to lease terms and restrictions, surface conditions,
identified hazards and environmental conditions to design a safe and efficient
well. The Company employs an integrated team concept in an effort to ensure
that a high degree of expertise in each of the disciplines is incorporated, to
ensure that the data are used properly in the technical evaluation and to
optimize the results of each phase of the exploration and development process.
 
Decision Making
 
If the technical evaluation has yielded positive results, the Company performs
a final economic analysis on the prospect prior to drilling. This analysis
includes estimates of reserves, production rates, drilling risks, costs and
probability of success. To determine probability of success, the Company
analyzes the quantity and quality of technical data used in the evaluation, as
well as the specific structural and stratigraphic attributes of the prospect
and the relationship of the prospect to analogous fields within the immediate
area.
 
INEXS
 
INEXS provides a complete range of geophysical and geological consulting
services, including prospect evaluation, complex 2-D and 3-D modeling, 3-D
seismic survey design, detailed seismic interpretation and fully integrated
field studies. INEXS operates as the project manager of 3-D surveys and as the
outsourced exploration and development department for several clients. INEXS
provides services for the Company and for major integrated, foreign national
and independent oil and gas companies. Since 1990, INEXS has performed over 180
detailed interpretation projects using 2-D and 3-D seismic data, remote sensing
data and available well information. INEXS's clients have drilled more than 100
wells based on INEXS's interpretation work, over 70% of which the Company
believes have been completed as commercial producers. Having formed working
relationships with a number of technology providers, INEXS gains access to
emerging technologies prior to their availability for general use by
participating in the design and testing of new geophysical applications.
 
INEXS's geologists and geophysicists have from 15 to 25 years experience in the
oil industry. Through the combined backgrounds of its staff, INEXS has
experience in all major petroleum regions of the world.
 
Although a wholly owned subsidiary of the Company, INEXS maintains a separate
identity from that of XPLOR. This separate identity is designed to maintain the
confidentiality necessary to perform consulting services for its other clients.
Many times, clients of INEXS are interested in finding an industry partner to
participate in their projects, and INEXS, with the consent of its clients,
offers XPLOR the opportunity to participate in such projects. The relationship
with INEXS has in the past provided, and the Company believes that the
relationship will in the future continue to provide, the Company with several
important benefits, including continuing industry relationships with INEXS's
client base, access to advanced exploration technology and an ongoing source of
prospects.

Set forth below are descriptions of the Company's key project areas where it is
actively exploring for oil and gas and the Company's properties that have
significant existing production. Unless otherwise indicated in the discussion
below, current production statistics are for the month of September 1997.
 
Louisiana Gulf Coast
 
The Company has ten active exploration projects in the Louisiana Gulf Coast
region. The Company has an inventory of 26 exploration and 17 development
drilling prospects based in part on its more than 275 square miles of
proprietary 3-D seismic data in the region. These prospects include an
aggregate of 30 drilling prospects associated with the Lapeyrouse, Lake Boeuf
and Egan/Jennings fields. The Company also has significant producing properties
in the region, including Main Pass 35 and Lake Raccourci. As of September 30,
1997, approximately 85% of the Company's proved reserves were concentrated in
the Louisiana Gulf Coast region. The Company has budgeted to drill 15
exploration prospects and 12 development prospects in 1998.
 
Main Pass 35. In 1996, the Company acquired a 70% working interest in Main Pass
35, located in the shallow state waters of Louisiana approximately 55 miles
southeast of New Orleans. This Company-operated field had average net
production of 480 BOE per day from Upper and Middle Miocene sands for the month
of September 1997. The Company has budgeted approximately $5.7 million through
the end of 1998 for development operations. The Company's 1997 budget includes
the purchase of an additional 25 square miles of 3-D seismic data to enhance
the exploitation of the field as well as to identify exploration opportunities.
 
                                       41
<PAGE>
 
Lapeyrouse. The Lapeyrouse project area is located in the coastal marshes of
southeast Louisiana in Terrebonne Parish, approximately 50 miles southwest of
New Orleans. The Company's working interest in this project ranges from 9% in
horizons below approximately 16,000 feet to 36% in shallower horizons. In 1996,
the Company acquired a 30 square mile proprietary 3-D seismic survey over the
project area as part of a larger regional shoot. The Company has completed the
processing and interpretation of the data and expects exploratory drilling to
commence in the first quarter of 1998. The targets consist of several untested
fault blocks of field productive sands and deeper potential reservoirs ranging
in depth from 13,000 to 20,000 feet. The Company has budgeted three exploratory
prospects and one development prospect to be drilled in 1998.
 
Lake Boeuf. The Lake Boeuf field is located in Lafourche Parish, Louisiana, 20
miles west of New Orleans. During the first half of 1997, the Company completed
a 30 square mile proprietary 3-D seismic survey covering the field and
associated prospects. The field adjoins the Southwest Lake Boeuf and the
Rousseau-Thibodeaux fields, which were discovered in the 1950s. Recent
exploratory efforts using high resolution 3-D seismic surveys have added
significant reserves to these nearby fields. The Company operates the project
with a 45% working interest and has identified several significant exploration
prospects and several prospects for shallower zones within the field. The
Company has budgeted three exploratory prospects and two development prospects
in 1998.
 
Egan/Jennings. The Company has acquired, processed and interpreted a 38 square
mile proprietary 3-D seismic survey covering both the Egan field and a portion
of the Jennings salt dome immediately west of the Egan field, located in Acadia
Parish, Louisiana. There are 11 structurally trapped objective sands of
Oligocene age ranging in depth from 9,000 to 14,000 feet. The Company has a 25%
working interest in this project and has budgeted nine exploratory and
development wells to be drilled in 1998.
 
Lake Raccourci. In 1995, the Company consummated a farm-in agreement in the
Lake Raccourci field located in Lafourche Parish, Louisiana, where the Company
has interpreted an existing third-party 3-D seismic survey covering
approximately 55 square miles. Since 1995, the Company has drilled five wells,
all of which have been completed as commercially productive. The Company's
working interest in the field varies from 39% in its two operated wells, both
of which produce from the Upper Miocene, to an average of 7% in its nonoperated
wells. The Company's average net production in Lake Raccourci for the month of
September 1997 was 2.5 MMcfe per day. The Company has identified an additional
development drilling location scheduled to be drilled in 1998.
 
Texas Gulf Coast
 
In the Texas Gulf Coast region, the Company has five active exploration
projects, including the Falcon project, the Hostetter project and the South
Texas project. The Company has an inventory of 43 exploratory and development
drilling prospects based in part on its approximately 200 square miles of
proprietary 3-D seismic data existing or in the process of being acquired in
the region. Of this inventory, 19 exploratory and two development prospects are
scheduled to be drilled in 1998.
 
Falcon. The Falcon Project is located in southwest Hardin County near the
Louisiana border. The Company controls over 9,000 acres under seismic options,
and expects to complete a 36 square mile proprietary 3-D seismic project in the
fourth quarter of 1997. The primary objectives in this project are the Yegua
sands ranging from 7,000 to 11,000 feet, and secondary objectives exist in the
shallower Miocene and Frio sands. The Company has identified several prospects
using conventional 2-D seismic data and subsurface well control. The Company
has a 52% working interest in this Company-operated project and expects to
commence exploratory drilling in 1998.
 
South Texas. The South Texas project areas are located in Duval County. Having
mapped and evaluated extensively this project area using subsurface well
control and 2-D seismic data, the Company has committed to acquire a minimum of
50 square miles of 3-D seismic data scheduled for completion in the first half
of 1998. The objectives include the 13 expanded Upper Wilcox Guerra sands
ranging from 10,000 to 13,000 feet that have demonstrated production to the
southwest at the Guerra field, to the northeast at the Rosita field, to the
southeast at the Muy Grande field and to the north at the East Seven Sisters
field. The Company is the operator of this project and currently has an 86%
working interest, a portion of which the Company expects to trade to an
industry partner, with a targeted working interest for the Company of
approximately 50%.

Hostetter. This exploration and development project, approximately 50 miles
west of Corpus Christi, is located in McMullen, Live Oak and Duval Counties
along the expanded Wilcox trend. The existing proprietary 3-D seismic survey
covers approximately 85 square miles shot over the Bonne Terre field, the
Hostetter field, the Rhode Ranch field and numerous other smaller fields. The
data collected from the survey have been acquired, processed and largely
interpreted, and the Company has identified 22 prospects. The Company has a 15%
working interest in the 30 prospective reservoirs within this project area
ranging from the shallow Frio sands to the deeper Upper Wilcox sands. The
majority of the prospects are located in the Upper Wilcox, in depths ranging
from 7,500 to 16,000 feet.
 
West Texas
 
The Company currently participates in three areas in West Texas, including two
exploratory projects in Reeves County and Garza County and production in
Crockett County. The Reeves project, located between Midland and El Paso,
includes a 72,320 acre checkerboard farmout from landowners in the area. The
Company has a 7.5% working interest in a 240 square mile proprietary 3-D
seismic project with targets ranging from the Permian Wolfcamp sands to the
deep Silurian-Devonian age limestones at depths ranging from 13,000 to 20,000
feet. The Garza Project covers several different counties in West Texas and
includes the Miller Ranch producing area. Over 76 square miles of proprietary
3-D seismic data have been acquired. Targets include the San Andres, Strawn and
Ellenburger formations. In the Adams-Baggett field, located in Crockett County,
the Company operates 93 wells that produce from multiple formations in the
Canyon Sand found at depths of approximately 5,000 feet. Net production from
such wells is approximately 881 Mcf per day, and the Company's working interest
is 100%.
 
General
 
Although the Company is currently pursuing prospects within the project areas
listed above, there can be no assurance that these prospects will be drilled
within the expected timeframe or at all. The final determination with respect
to the drilling of any scheduled or budgeted wells will be dependent on a
number of factors, including (i) the results of exploration efforts and the
acquisition, review and analysis of the seismic data, (ii) the availability of
sufficient capital resources by the Company and other participants for drilling
the prospects, (iii) the approval of the prospects by other participants after
additional data have been compiled, (iv) economic and industry conditions at
the time of drilling, including prevailing and anticipated prices for gas and
oil and the availability of drilling rigs and crews, (v) the financial
resources and results of the Company and (vi) the permitting for the prospect.
There can be no assurance that these prospects can be successfully developed or
that the scheduled or budgeted wells discussed will, if drilled, encounter
reservoirs of commercially productive gas or oil. The reserve data set forth
above are based upon the Netherland Sewell Report. There are numerous
uncertainties in estimating quantities of proved reserves, including many
factors beyond the control of the Company. See "Risk Factors--Dependence on
Exploratory Drilling Activities," "--Reserve Replacement Risk" and
"--Uncertainty of Reserve Information and Future Net Revenue Estimates."

OIL AND GAS RESERVES
 
The following table sets forth estimated net proved oil and gas reserves of the
Company and the present value of estimated future pretax net cash flows related
to such reserves as of December 31, 1996, on a combined basis giving effect to
the Combination Transaction, and as of September 30, 1997. The reserve data and
the present value as of December 31, 1996 and September 30, 1997 were prepared
by Netherland Sewell. For further information concerning Netherland Sewell's
estimates, see Netherland Sewell's letter included as Appendix A to this
Prospectus. The present value of estimated future net revenues before income
taxes was prepared using constant prices as of the calculation date, discounted
at 10% per annum on a pretax basis, and is not intended to represent the
current market value of the estimated oil and gas reserves owned by the
Company. For further information concerning the present value of future net
revenue from these proved reserves, see the Notes to the Consolidated Financial
Statements of Araxas and the South Coast Companies. Also see "Risk Factors--
Uncertainty of Reserve Information and Future Net Revenue Estimates."

(1) The prices used as of December 31, 1996 averaged $24.23 per Bbl of oil and
$3.97 per Mcf of gas and do not give effect to hedging arrangements required by
the Stratum debt agreement. During September 1997, the Company closed all of
its outstanding hedging arrangements. See "--Marketing" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Hedging." Giving effect to such hedging arrangements, the prices used as of
December 31, 1996 would have been $18.10 per Bbl of oil and $3.49 per Mcf of
gas, and estimated future net revenues before income taxes and present value of
estimated future net revenues before income taxes as of such date would have
been $158,732,000 and $86,534,000, respectively.
(2) The prices used as of September 30, 1997 averaged $19.93 per Bbl of oil and
$2.60 per Mcf of gas.
(3) The declines in proved reserves from December 31, 1996 to September 30,
1997 reflect production during the period and the exclusion of certain reserves
that were no longer economic at September 30, 1997 prices. During this period,
the Company's capital constraints limited additions to proved reserves.
(4) The present value of estimated future net revenues attributable to the
Company's reserves was prepared using constant prices as of the calculation
date (see Note 1), discounted at 10% per annum on a pretax basis.
 
There are numerous uncertainties inherent in estimating quantities of proved
oil and gas reserves and in projecting future rates of production and timing of
development expenditures, including many factors beyond the control of the
producer. The reserve data set forth herein represent estimates only. Reserve
engineering is a subjective process of estimating underground accumulations of
oil and gas that cannot be measured in an exact way, and the accuracy of any
reserve estimate is a function of the quality of available data and of
engineering and geological interpretation and judgment. As a result, estimates
made by different engineers often vary from one another. In addition, results
of drilling, testing and production subsequent to the date of an estimate may
justify revision of such estimates, and such revisions may be material.
Accordingly, reserve estimates are generally different from the quantities of
oil and gas that are ultimately recovered. Furthermore, the estimated future
net revenues from proved reserves and the present value thereof are based upon
certain assumptions, including future prices, production levels and costs, that
may not prove correct.

No estimates of proved reserves comparable to those included herein have been
included in reports to any federal agency other than the Commission.
 
In accordance with applicable requirements of the Commission, the Netherland
Sewell Reports used oil and gas prices in effect at December 31, 1996 and
September 30, 1997. The prices used in calculating the estimated future net
revenue attributable to proved reserves do not necessarily reflect market
prices for oil and gas production subsequent to such date. There can be no
assurance that all of the proved reserves will be produced and sold within the
periods indicated, that the assumed prices will actually be realized for such
production or that existing contracts will be honored or judicially enforced.

DEVELOPMENT, EXPLORATION AND ACQUISITION COSTS
 
From December 31, 1994 to September 30, 1997, the Company incurred total
development, exploration and acquisition costs of approximately $45.6 million.
Total exploration, development and acquisition activities from December 31,
1994 to September 30, 1997 have resulted in the addition of approximately 66
Bcfe, net to the Company's interest, of proved reserves at an average reserve
replacement cost of $0.71 per Mcfe. Reserve replacement costs reflect the
proceeds from the sales of unproved prospects.
 
The following table sets forth certain information regarding the costs incurred
by the Company in the acquisition of proved and unproved properties and in
development and exploration activities.

Costs incurred do not reflect sales of proved properties, which are accounted
for as adjustments of capitalized costs with no gain or loss recognized, unless
such adjustments would significantly alter the relationships between
capitalized costs and proved reserves. The Company's development, exploration
and acquisition costs have historically fluctuated on a year-to-year basis.
Such costs, as measured annually, may not be indicative of the Company's
ability to replace oil and gas reserves economically, because the recognition
of costs may not necessarily coincide with the addition of proved reserves.
 
DRILLING ACTIVITY

a right to acquire pursuant to various farm-in and seismic option agreements.
 
MARKETING
 
The Company's production is marketed to third parties consistent with industry
practices. Typically, oil is sold at the wellhead at field-posted prices plus a
bonus, and gas is sold under contract at a negotiated price based upon factors
normally considered in the industry, such as distance from the well to the
pipeline, well pressure, estimated reserves, quality of gas and prevailing
supply and demand conditions.
 
The Company's marketing objective is to receive the highest possible wellhead
price for its product. The Company is aided by the presence of significant
infrastructure near its production in the Gulf Coast. The Company takes an
active role in determining the available pipeline alternatives for each
property based upon historical pricing, capacity, pressure, market
relationships, seasonal variances and long-term viability.
 
There are a variety of factors that affect the market for oil and gas,
including the extent of domestic production and imports of oil and gas, the
proximity and capacity of gas pipelines and other transportation facilities,
demand for oil and gas, the marketing of competitive fuels and the effects of
state and federal regulations on oil and gas production and sales. The Company
has not experienced any difficulties in marketing its oil and gas. The oil and
gas industry also competes with other industries in supplying the energy and
fuel requirements of industrial, commercial and individual customers.
 
The Company is subject to price fluctuations for gas sold in the spot market
due primarily to seasonality of demand and other factors beyond the Company's
control. Domestic oil prices generally follow worldwide oil prices, which are
subject to price fluctuations resulting from changes in world supply and
demand. The Company's former debt agreement with Stratum required the Company
to put into place significant long-term hedging arrangements in an effort to
reduce price risk. The Company repaid and terminated the Stratum debt agreement
in September
 
                                       47
<PAGE>
 
1997, and the Credit Agreement does not require the Company to maintain hedges.
During September 1997, the Company closed all of its outstanding hedging
arrangements, resulting in losses of $2.8 million. During the year ended
December 31, 1996, the Company received a fixed price and paid the NYMEX price
with respect to 575 MMBtus of gas and 60 MBbls of oil under commodity price
arrangements, realizing losses of $598,000. During the first six months of
1997, the Company received a fixed price and paid the NYMEX price with respect
to 338 MMBtus of gas and 177 MBbls of oil under commodity price arrangements,
realizing losses of $739,000. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Hedging." The Company currently
does not intend to hedge more than one-third of its production, but may
reevaluate its hedging policy from time to time. The Company may also close out
any portion of hedges that may exist from time to time as determined to be
appropriate by management.
 
COMPETITION
 
The Company encounters competition from other oil and gas companies in all
areas of its operations, including the acquisition of exploratory prospects and
proven properties. The Company's competitors include major integrated oil and
gas companies and numerous independent oil and gas companies, individuals and
drilling and income programs. Many of its competitors are large, well-
established companies that have substantially larger operating staffs and
greater capital resources than those of the Company and that, in many
instances, have been engaged in the oil and gas business for a much longer time
than the Company. Such companies may be able to pay more for exploratory
prospects and productive oil and gas properties and may be able to identify,
evaluate, bid for and purchase a greater number of properties and prospects
than the Company's financial or human resources permit. In addition, such
companies may be able to expend greater resources on the existing and changing
technologies that the Company believes are and will be increasingly important
to the current and future success of oil and gas companies. The Company's
ability to explore for oil and gas prospects and to acquire additional
properties in the future will be dependent upon its ability to conduct its
operations, to evaluate and select suitable properties and to consummate
transactions in this highly competitive environment. The Company believes that
its exploration, drilling and production capabilities and the experience of its
management and technical staff enable it to compete effectively. Many of the
Company's competitors, however, have financial resources and exploration and
development budgets that are substantially greater than those of the Company,
which may adversely affect the Company's ability to compete with these
companies.
 
REGULATION
 
The availability of a ready market for oil and gas production depends upon
numerous factors beyond the Company's control. These factors include regulation
of oil and gas production, federal and state regulations governing
environmental quality and pollution control, state limits on allowable rates of
production by well or proration unit, the amount of oil and gas available for
sale, the availability of adequate pipeline and other transportation and
processing facilities and the marketing of competitive fuels. For example, a
productive gas well may be "shut-in" because of an oversupply of gas or lack of
an available gas pipeline in the areas in which the Company may conduct
operations. State and federal regulations generally are intended to prevent
waste of oil and gas, protect rights to produce oil and gas between owners in a
common reservoir, control the amount of oil and gas produced by assigning
allowable rates of production and control contamination of the environment.
Pipelines are subject to the jurisdiction of various federal, state and local
agencies. The following discussion summarizes the regulation of the United
States oil and gas industry. The Company believes that it is in substantial
compliance with such statutes, rules, regulations and governmental orders,
although there can be no assurance that this is or will remain the case. The
following discussion is not intended to constitute a complete discussion of the
various statutes, rules, regulations and governmental orders to which the
Company's operations may be subject.
 
Regulation of Oil and Gas Exploration and Production
 
The Company's operations are subject to various types of regulation at the
federal, state and local levels. Such regulation includes requiring permits for
the drilling of wells, maintaining bonding requirements to drill or operate
 
                                       48
<PAGE>
 
wells and regulating the location of wells, the method of drilling and casing
wells, the surface use and restoration of properties upon which wells are
drilled, the plugging and abandoning of wells and the disposal of fluids used
in connection with operations. The Company's operations are also subject to
various conservation laws and regulations. These include the regulation of the
size of drilling and spacing units or proration units and the density of wells
that may be drilled in and the unitization or pooling of oil and gas
properties. In this regard, some states allow the forced pooling or integration
of tracts to facilitate exploration while other states rely primarily or
exclusively on voluntary pooling of lands and leases. In areas where pooling is
voluntary, it may be more difficult to form units, and therefore more difficult
to develop a project, if the operator owns less than 100% of the leasehold. In
addition, state conservation laws establish maximum rates of production from
oil and gas wells, generally prohibit the venting or flaring of gas and impose
certain requirements regarding the ratability of production. The effect of
these regulations may limit the amount of oil and gas the Company can produce
from its wells and may limit the number of wells or the locations at which the
Company can drill. The regulatory burden on the oil and gas industry increases
the Company's costs of doing business and, consequently, affects its
profitability. Inasmuch as such laws and regulations are frequently expanded,
amended and reinterpreted, the Company is unable to predict the future cost or
impact of complying with such regulations.
 
Regulation of Sales and Transportation of Gas
 
Historically, the transportation and sale for resale of gas in interstate
commerce have been regulated pursuant to the Gas Act of 1938 (the "NGA"), the
Gas Policy Act of 1978 (the "NGPA") and the regulations promulgated thereunder
by the Federal Energy Regulatory Commission (the "FERC"). Maximum selling
prices of certain categories of gas sold in "first sales," whether sold in
interstate or intrastate commerce, were regulated pursuant to the NGPA. The Gas
Wellhead Decontrol Act (the "Decontrol Act") removed, as of not later than
January 1, 1993, all remaining federal price controls from gas sold in "first
sales." The FERC's jurisdiction over gas transportation was unaffected by the
Decontrol Act. Although sales by producers, such as the Company, of gas and all
sales of crude oil, condensate and gas liquids can currently be made at market
prices, Congress could reenact price controls in the future.
 
The Company's sales of gas are affected by the availability, terms and cost of
transportation. The price and terms for access to pipeline transportation are
subject to extensive regulation. In recent years, the FERC has undertaken
various initiatives to increase competition within the gas industry. As a
result of initiatives like FERC Order No. 636, issued in April 1992, the
interstate gas transportation and marketing system has been substantially
restructured to remove various barriers and practices that historically limited
non-pipeline gas sellers, including producers, from effectively competing with
interstate pipelines for sales to local distribution companies and large
industrial and commercial customers. The most significant provisions of Order
No. 636 require that interstate pipelines provide transportation separate or
"unbundled" from their sales service, and require that pipelines provide firm
and interruptible transportation service on an open access basis that is equal
for all gas supplies. In many instances, the result of Order No. 636 and
related initiatives has been to reduce substantially or eliminate the
interstate pipelines' traditional role as wholesalers of gas in favor of
providing only storage and transportation services.
 
The FERC has announced several important transportation-related policy
statements and proposed rule changes, including a statement of policy and a
request for comments concerning alternatives to its traditional cost-of-service
ratemaking methodology to establish the rates interstate pipelines may charge
for their services. A number of pipelines have obtained FERC authorization to
charge negotiated rates as one such alternative. In February 1997, the FERC
announced a broad inquiry into issues facing the gas industry to assist the
FERC in establishing regulatory goals and priorities in the post-Order No. 636
environment. Similarly, the Texas Railroad Commission has been reviewing
changes to its regulations governing transportation and gathering services
provided by intrastate pipelines and gatherers, and recently implemented a code
of conduct intended to prevent undue discrimination by intrastate pipelines and
gatherers in favor of their marketing affiliates. Although the changes being
considered by these federal and state regulators would affect the Company only
indirectly, they are intended to further enhance competition in gas markets.
 
                                       49
<PAGE>
 
The Company owns certain gas pipelines that it believes meet the standards the
FERC has used to establish a pipeline's status as a gatherer not subject to
FERC jurisdiction under the NGA. State regulation of gathering facilities
generally includes various safety, environmental, and in some circumstances,
nondiscriminatory take requirements, but does not generally entail rate
regulation. Gas gathering may receive greater regulatory scrutiny at both state
and federal levels in the post-Order No. 636 environment.
 
The Company cannot predict what further action the FERC or state regulators
will take on these matters; the Company does not believe, however, that it will
be affected by any action taken materially differently than other gas producers
with which it competes.
 
Additional proposals and proceedings that might affect the gas industry are
pending before Congress, the FERC, state commissions and the courts. The gas
industry historically has been very heavily regulated; therefore, there is no
assurance that the less stringent regulatory approach recently pursued by the
FERC and Congress will continue.
 
Oil Price Controls and Transportation Rates
 
Sales of crude oil, condensate and gas liquids by the Company are not currently
regulated and are made at market prices. The price the Company receives from
the sale of these products may be affected by the cost of transporting the
products to market. Effective January 1995, the FERC implemented regulations
establishing an indexing system under which oil pipelines will be able to
change their transportation rates, subject to prescribed ceiling limits. The
indexing system generally indexes such rates to inflation, subject to certain
conditions and limitations. The Company is not able at this time to predict the
effects of these regulations, if any, on the transportation costs associated
with oil production from the Company's oil producing operations.
 
Environmental Regulations
 
The Company's operations are subject to numerous federal, state and local laws
and regulations governing the discharge of materials into the environment or
otherwise relating to environmental protection. These laws and regulations may
require the acquisition of a permit before drilling commences, restrict the
types, quantities and concentration of various substances that can be released
into the environment in connection with drilling and production activities,
limit or prohibit drilling activities on certain lands within wilderness,
wetlands and other protected areas, require remedial measures to mitigate
pollution from former operations, such as pit closure and plugging abandoned
wells, and impose substantial liabilities for pollution resulting from
production and drilling operations. Public interest in the protection of the
environment has increased dramatically in recent years. The trend of more
expansive and stricter environmental legislation and regulations as applied to
the oil and gas industry could continue, resulting in increased costs of doing
business and consequently affecting profitability. To the extent laws are
enacted or other governmental action is taken that restricts drilling or
imposes more stringent and costly waste handling, disposal and cleanup
requirements, the business and prospects of the Company could be adversely
affected.
 
The Company generates wastes that may be subject to the federal Resource
Conservation and Recovery Act ("RCRA") and comparable state statutes. The U.S.
Environmental Protection Agency ("EPA") and various state agencies have limited
the approved methods of disposal for certain hazardous and nonhazardous wastes.
Furthermore, certain wastes generated by the Company's oil and gas operations
that are currently exempt from treatment as "hazardous wastes" may in the
future be designated as "hazardous wastes," and therefore be subject to more
rigorous and costly operating and disposal requirements.
 
The Company currently owns or leases numerous properties that for many years
have been used for the exploration and production of oil and gas. Although the
Company believes that it has used good operating and waste disposal practices,
prior owners and operators of these properties may not have used similar
practices, and hydrocarbons or other wastes may have been disposed of or
released on or under the properties owned or leased by the Company or on or
under locations where such wastes have been taken for disposal. In addition,
many of
 
                                       50
<PAGE>
 
these properties have been operated by third parties whose treatment and
disposal or release of hydrocarbons or other wastes was not under the Company's
control. These properties and the wastes disposed thereon may be subject to the
Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA"), RCRA and analogous state laws as well as state laws governing the
management of oil and gas wastes. Under such laws, the Company could be
required to remove or remediate previously disposed wastes (including wastes
disposed of or released by prior owners or operators) or property contamination
(including groundwater contamination) or to perform remedial plugging
operations to prevent future contamination.
 
The Company's operations may be subject to the Clean Air Act ("CAA") and
comparable state and local requirements. Amendments to the CAA were adopted in
1990 and contain provisions that may result in the gradual imposition of
certain pollution control requirements with respect to air emissions from the
operations of the Company. The EPA and states have been developing regulations
to implement these requirements. The Company may be required to incur certain
capital expenditures in the next several years for air pollution control
equipment in connection with maintaining or obtaining operating permits and
approvals addressing other air emission-related issues. In addition, the
Company is currently involved in discussions with the Louisiana Department of
Environmental Quality ("LDEQ") regarding the late submittal of a Title V
operating permit application and the installation of necessary air pollution
control equipment. LDEQ has accepted the Company's proposals, and the Company
does not believe that its operations will be materially adversely affected by
these matters or any other future CAA requirements.
 
Federal regulations require certain owners or operators of facilities that
store or otherwise handle oil, such as the Company, to prepare and implement
spill prevention, control, countermeasure ("SPCC") and response plans relating
to the possible discharge of oil into surface waters. The Company has
acknowledged the need to update its SPCC plans at certain of its properties and
believes that it will be able to update and implement these plans in the near
future. The Oil Pollution Act of 1990 ("OPA") contains numerous requirements
relating to the prevention of and response to oil spills into waters of the
United States. The OPA subjects owners of facilities to strict joint and
several liability for all containment and cleanup costs and certain other
damages arising from a spill, including, but not limited to, the costs of
responding to a release of oil to surface waters. The OPA also requires owners
and operators of offshore facilities that could be the source of an oil spill
into federal or state waters, including wetlands, to post a bond, letter of
credit or other form of financial assurance in amounts ranging from $10 million
in specified state waters to $35 million in federal outer continental shelf
waters to cover costs that could be incurred by governmental authorities in
responding to an oil spill. Such financial assurances may be increased by as
much as $150 million if a formal assessment indicates such an increase is
warranted. Noncompliance with OPA may result in varying civil and criminal
penalties and liabilities. Operations of the Company are also subject to the
federal Clean Water Act ("CWA") and analogous state laws. In accordance with
the CWA, the state of Louisiana has issued regulations prohibiting discharges
of produced water in state coastal waters effective July 1, 1997. To comply
with these Louisiana regulations, the Company has undertaken extensive physical
and operational modifications to eliminate the discharge of produced water into
Louisiana coastal waters. Although currently in full compliance with
Louisiana's regulations prohibiting the discharge of produced waters into
Louisiana coastal waters, the Company may incur additional capital expenses of
up to $1.0 million and additional operating expenses of up to $200,000 every
two years to remain in compliance with the produced water discharge prohibition
without curtailing production. Pursuant to other requirements of the CWA, the
EPA has adopted regulations concerning discharges of storm water runoff. This
program requires covered facilities to obtain individual permits, participate
in a group permit or seek coverage under an EPA general permit. While certain
of its properties may require permits for discharges of storm water runoff, the
Company believes that it will be able to obtain, or be included under, such
permits, where necessary, and make minor modifications to existing facilities
and operations that would not have a material effect on the Company. Like OPA,
the CWA and analogous state laws relating to the control of water pollution
provide varying civil and criminal penalties and liabilities for releases of
petroleum or its derivatives into surface waters or into the ground.
 
CERCLA, also known as the "Superfund" law, and similar state laws impose
liability, without regard to fault or the legality of the original conduct, on
certain classes of persons that are considered to have contributed to the
 
                                       51
<PAGE>
 
release of a "hazardous substance" into the environment. These persons include
the owner or operator of the disposal site or sites where the release occurred
and companies that disposed or arranged for the disposal of the hazardous
substances found at the site. Persons who are or were responsible for releases
of hazardous substances under CERCLA may be subject to joint and several
liability for the costs of cleaning up the hazardous substances that have been
released into the environment, for damages to natural resources and for the
costs of certain health studies, and it is not uncommon for neighboring
landowners and other third parties to file claims for personal injury and
property damage allegedly caused by the hazardous substances released into the
environment.
 
The Company also is subject to a variety of federal, state and local permitting
and registration requirements relating to protection of the environment. Except
with respect to certain CAA matters described above, management believes that
the Company is in substantial compliance with current applicable environmental
laws and regulations. Management also believes continued compliance with
existing requirements will not have a material adverse effect on the Company.
 
OPERATING HAZARDS AND INSURANCE
 
The oil and gas business involves a variety of operating risks, including the
risk of fire, explosion, blow-out, pipe failure, casing collapse, abnormally
pressured formations and environmental hazards such as oil spills, gas leaks,
ruptures and discharges of toxic gases, the occurrence of any of which could
result in substantial losses to the Company due to injury or loss of life,
severe damage to or destruction of property, natural resources and equipment,
pollution or other environmental damage, cleanup responsibilities, regulatory
investigation and penalties and suspension of operations.
 
In accordance with customary industry practice, the Company maintains insurance
against some, but not all, of the risks described above. The Company's
insurance covers business interruption and loss of revenues in certain limited
circumstances, including force majeure, but does not protect against certain
losses related to environmental matters. There can be no assurance that any
insurance obtained by the Company will be adequate to cover any losses or
liabilities. The Company cannot predict the continued availability of insurance
or the availability of insurance at premium levels that justify its purchase.
The occurrence of a significant event not fully insured or indemnified against
could materially and adversely affect the Company's financial condition and
operations.
 
TITLE TO PROPERTIES
 
The Company believes it has satisfactory title to all of its producing
properties in accordance with standards generally accepted in the oil and gas
industry. The Company's properties are subject to customary royalty interests,
liens incident to operating agreements, liens for current taxes and other
burdens that the Company believes do not materially interfere with the use of
or affect the value of such properties. As is customary in the industry in the
case of undeveloped properties, little investigation of record title is made at
the time of acquisition (other than a preliminary review of local records).
Investigations, including a title opinion of local counsel, are generally made
before commencement of drilling operations. The Credit Agreement is secured by
all of the Company's oil and gas properties.
 
EMPLOYEES
 
At September 30, 1997, the Company had 32 full-time employees and seven
contract employees. As drilling and production activities increase, the Company
intends to hire additional technical, operational and administrative personnel
as appropriate. The Company believes that its relationships with its employees
are good. None of the Company's employees are covered by a collective
bargaining agreement. From time to time, the Company uses the services of
independent consultants and contractors to perform various professional
services, particularly in the areas of acquisition of leases and lease options,
construction, design, well site surveillance, permitting and environmental
assessment. Field and on-site production operation services, such as pumping,
maintenance, dispatching, inspection and testing, are generally provided by
independent contractors. The
 
                                       52
<PAGE>
 
Company believes that this use of third-party service providers has enhanced in
the past, and will continue to enhance in the future, its ability to contain
general and administrative expenses.
 
LEGAL PROCEEDINGS
 
From time to time the Company is a party to various legal proceedings arising
in the ordinary course of business. The Company is not currently a party to any
litigation that it believes could have a material adverse effect on the
financial position, results of operations or liquidity of the Company.

(1) Appointment will become effective upon closing of the Offering.
 
The Company's Board of Directors is divided into three classes with staggered
terms of office, initially ending as set forth above. Thereafter, the term for
each class will expire on the date of the third annual stockholders' meeting
for the election of directors following the most recent election of directors
for such class. Each director holds office until the next annual meeting of
stockholders for the election of directors of his class and until his successor
has been duly elected and qualified. Officers serve at the discretion of the
Board of Directors.
 
Effective upon closing of the Offering, there will be two standing committees
of the Board of Directors: an Audit Committee and a Compensation Committee. The
Audit Committee will recommend the appointment of independent public
accountants to conduct audits of the Company's financial statements, review
with the independent accountants the plan and results of the auditing
engagement, approve other professional services provided by the independent
accountants and evaluate the independence of the accountants. The Audit
Committee will also review the scope and results of procedures for internal
auditing of the Company and the adequacy of the Company's system of internal
accounting controls. The Compensation Committee will approve, or in some cases
recommend to the Board, remuneration arrangements and other compensation plans
involving the Company's directors, executive officers and certain other
employees and consultants whose compensation exceeds specified levels. The
Compensation Committee will also act on the granting of stock options,
including under the Incentive Plan. The members of the Audit and Compensation
Committees will not be employees of the Company.

attendance at each Board of Directors meeting and $500 for each committee
meeting (unless held on the same day as a Board of Directors meeting). All
directors will be reimbursed for out-of-pocket expenses incurred in attending
meetings of the Board of Directors or committees thereof and for other expenses
incurred in their capacity as directors. In connection with the Offering, each
nonemployee director will receive options to purchase 10,000 shares of Common
Stock at a price per share equal to the initial public offering price per share
set forth on the cover page of this Prospectus. Such options will have a term

OFFICER AND DIRECTOR INDEMNIFICATION
 
The Company's Bylaws provide for the indemnification of its officers and
directors, and the advancement to them of expenses in connection with
proceedings and claims, to the fullest extent permitted by the Delaware General
Corporation Law. The Bylaws include related provisions meant to facilitate the
indemnitee's receipt of such benefits. These provisions cover, among other
things: (i) specification of the method of determining entitlement to
indemnification and the selection of independent counsel that will in some
cases make such determination; (ii) specification of certain time periods by
which certain payments or determinations must be made and actions must be taken
and (iii) the establishment of certain presumptions in favor of an indemnitee.
The benefits of certain of these provisions are available to an indemnitee only
if there has been a change in control (as defined therein). The Company intends
to enter into indemnification agreements with its directors and officers that
provide for similar protections. In addition, the Company expects to purchase a
directors' and officers' liability insurance policy prior to the consummation
of the Offering.

- --------
(1) Effective January 1, 1998, Mr. Nance's base salary will be increased to
$225,000 per year. His bonus for 1997 will be $200,000, subject to certain
conditions.
(2) Mr. Krenzke's bonus for 1997 will be $125,000.
 
Each agreement also entitles the employee to participate in the Company's
employee benefit plans, executive compensation plans and insurance and welfare
benefit plans in which other officers of the Company participate, including the
Incentive Plan. Each agreement provides that the employee's annual base salary
shall be reviewed annually and may be increased as determined by the
Compensation Committee or the Board of Directors.
 
Each of the agreements has an initial three-year term, and beginning at the end
of the second year of such initial term, the term will be automatically
extended such that there shall always be at least one year remaining on the
term of the agreement. Each agreement will be subject to the right of the
Company and the employee to terminate the employee's employment at any time.
Each agreement provides that, upon termination of employment because of death,
the employee will generally be entitled to a lump sum payment equal to a pro
rata share of the employee's annual base salary or incentive compensation or
both based on the number of days in the year that elapsed prior to termination.
Upon termination of employment because of illness or other incapacity, the
employee will generally be entitled to (i) compensation for the remaining term
of the agreement, but in no event less than one year, if the Company has not
provided disability insurance, (ii) a pro rata share of the employee's
incentive compensation based on the number of days in the year that elapsed
prior to termination and (iii) other benefits as determined by the Company.
Upon termination of employment for any other reason (except under certain
limited circumstances defined as "for cause" in the agreements), or if
employment is terminated by the employee subsequent to a change of control (as
defined) or with good reason (as defined), the employee generally will be
entitled to (i) compensation for the remaining term of the agreement, but in no
event less than one year (two years for a change of control), and (ii) all
incentive compensation that would have been paid to the employee as if all
performance goals had been met during the balance of the term of the agreement,
but in no event less than one annual incentive bonus (two annual incentive
bonuses for a change of control). Except in the case of Mr. Nance and Mr.
Clark, upon termination for any reason other than for cause, the employee will
be entitled to immediate vesting of any stock options or restricted stock
awards previously granted to such employee and outstanding as of the time
immediately prior to the date of his termination. The Company will also pay the
employee (other than Mr. Clark) any such amount as may be necessary to hold the
employee harmless from the consequences of any resulting excise or other
similar purpose tax relating to "parachute payments" under the Internal Revenue
Code of 1986, as amended.
 
Each agreement also provides that, during the term of the agreement and after
termination thereof, the employee shall not impart to any person any of the
Company's proprietary or confidential information, subject to limited
exceptions. In addition, each agreement provides that, for six months following
termination of the employee's employment, the employee will not (i) own,
operate, be employed by or participate in a business conducted by a
 
                                       58
<PAGE>
 
competitor of the Company or (ii) contact or encourage others to contact any
employee of the Company for the purpose of recruiting such employee for another
employer.
 
Pursuant to his employment agreement, Mr. Nance received a restricted grant of
    shares of Common Stock and options to acquire an additional     shares of
Common Stock. The restricted stock awards and the options become vested in
cumulative annual increments of one-third beginning on January 21, 1998, and
become fully exercisable upon a change of control. The options have an exercise
price of $    per share and expire in January 2007.
 
Pursuant to his employment agreement, Mr. Clark received options to acquire
shares of Common Stock in accordance with the Incentive Plan. The options
become vested in cumulative annual increments of one-third beginning on the
first anniversary of the closing of the Offering. The options have an exercise
price of $    per share and a term of ten years.
 
INCENTIVE PLAN
 
The Company has adopted the Incentive Plan, the objectives of which are to
retain selected employees and independent contractors and consultants of the
Company and reward them for making significant contributions to the success of
the Company by making awards ("Awards") designed to provide participants in the
Incentive Plan with a proprietary interest in the growth and performance of the
Company. Persons eligible for Awards under the Incentive Plan include employees
of the Company and certain nonemployee consultants and other independent
contractors providing services to the Company.
 
The Compensation Committee of the Company's Board of Directors (the
"Committee") will administer the Incentive Plan. The Committee has exclusive
power to interpret the Incentive Plan and to adopt such rules, regulations and
guidelines for carrying out the Incentive Plan as it may deem necessary or
proper, all of which powers shall be exercised in the best interests of the
Company and in keeping with the objectives of the Incentive Plan. The Committee
may delegate to the President and other senior officers of the Company its
duties under the Incentive Plan.
 
The Board of Directors may amend, modify, suspend or terminate the Incentive
Plan for the purpose of meeting or addressing any changes in legal requirements
or for any other lawful purpose, except that (i) no amendment or alteration
that would impair the rights of any participant under any Award previously
granted to such participant shall be made without such participant's consent
and (ii) no amendment or alteration shall be effective prior to approval by the
Company's stockholders to the extent such approval is then required pursuant to
Rule 16b-3 under the Exchange Act to preserve the applicability of any
exemption provided by such rule to any Award then outstanding (unless the
holder of such Award consents) or to the extent stockholder approval is
otherwise required by applicable legal requirements. The Board of Directors may
make certain adjustments in the event of any subdivision or consolidation of
outstanding shares of Common Stock or declaration of a dividend payable in
shares of Common Stock or capital reorganization or reclassification or other
transaction involving an increase or reduction in the number of outstanding
shares of Common Stock, any consolidation or merger of the Company with another
corporation or entity or the adoption by the Company of a plan of exchange
affecting the Common Stock or any distribution to holders of Common Stock of
securities or property (other than normal cash dividends or dividends payable
in Common Stock).
 
Awards may be in the form of (i) rights to purchase a specified number of
shares of Common Stock at a specified price (an "Option"), (ii) rights to
receive a payment, in cash or Common Stock, equal to the excess of the fair
market value or other specified value of a number of shares of Common Stock on
the rights exercise date over a specified strike price, (iii) grants of
restricted or unrestricted Common Stock or units denominated in Common Stock
("Stock Awards") and (iv) grants denominated in cash. An Option granted to an
employee may be in the form of an incentive stock option that complies with the
requirements of Section 422 of the Internal Revenue Code of 1986, as amended.
The Committee will determine the type or types of Awards to be made to each
participant under the Incentive Plan, and the terms, conditions and limitations
applicable to each such Award. With respect to Stock Awards, such conditions
may include, but are not limited to, continuous service with the
 
                                       59
<PAGE>
 
Company, achievement of specific business objectives, increases in specified
indices, attaining specified growth rates and other comparable measurements of
performance.
 
Unless otherwise specifically provided in the related option agreement, each
Option granted under the Incentive Plan will provide that if the participant
ceases to be employed by the Company or its affiliates for any reason
whatsoever, the Option will immediately terminate to the extent the Option is
not vested (or does not become vested as a result of such termination of
employment) on the date the participant terminates employment.
 
The occurrence of a change of control of the Company shall result in
acceleration of the vesting and exercisability of, and lapse of restrictions
with respect to, all Awards granted under the Incentive Plan. For purposes of
this provision, a "change of control" means (i) any sale by the Company of
substantially all of its assets or (ii) the acquisition by any "person,"
including a "group" as determined in accordance with Section 13(d)(3) under the
Exchange Act, of beneficial ownership, directly or indirectly, of securities of
the Company representing 50% or more of the combined voting power of the
Company's then-outstanding securities. No change of control shall be deemed to
occur, however, if beneficial ownership in the Company's then-outstanding
securities is acquired pursuant to any reorganization of the Company or
recapitalization, spinoff or other transaction if, after giving effect to such
transaction, however structured, at least 50% of the outstanding voting
securities with the ultimate parent entity corporation are beneficially owned
in the aggregate, directly or indirectly through one or more intermediaries, by
the former stockholders of the Company.
 
The Company has reserved     shares of Common Stock, subject to adjustment, for
use in connection with the Incentive Plan. Options under the Incentive Plan
have been granted to approximately 39 employees and contractors of the Company
to purchase a total of approximately     shares of Common Stock at an exercise
price per share equal to $    . All such Options have a term of ten years and
become exercisable in cumulative annual increments of one-third of the total
number of shares of Common Stock subject thereto, beginning on the first
anniversary of the closing date of the Offering.
 
The foregoing description summarizes the principal terms and conditions of the
Incentive Plan, does not purport to be complete and is qualified in its
entirety by reference to the Incentive Plan, a copy of which has been filed as
an exhibit to the Registration Statement of which this Prospectus is a part.
 
INCENTIVE BONUSES
 
The Company intends to grant incentive bonuses designed to provide all
employees of the Company with short-term cash incentives to meet operational
and financial targets. The amount of bonus paid to an individual will be based
on his or her performance and contribution as well as the overall performance
of the Company. In general, participation levels are related to the
individual's ability to influence the Company's operational or financial
results. Maximum bonus levels for executive officers will be determined by the
Compensation Committee and will range from 40% to 100% of salary, and maximum
bonus levels for other employees will be determined by the executive officers
and will range from 10% to 40% of salary. Total funding of the incentive
bonuses will be subject to approval by the Board of Directors.
 
OTHER COMPENSATORY ARRANGEMENTS
 
Overriding Royalty Interests
 
In the past, the Company has granted overriding royalty interests on prospects
generated and developed by the Company to a pool of professional employees
comprising geoscientists, land personnel and other persons, including executive
officers. The percentage of overriding royalty interest assigned to the pool
pursuant to this arrangement for a given lease typically has ranged from 2% to
3% of the Company's total interest in such lease. An individual employee's
overriding royalty interest in a lease was contractual, and such interest was
not subject to forfeiture in the event the employee left the Company.
 
 
                                       60
<PAGE>
 
As a result of the Combination Transaction, there are no outstanding overriding
royalty interests on undrilled prospects held by executive officers or
directors. In the future, the Company intends to assign or grant overriding
royalty interests only to nonexecutive members of the technical team and only
on undrilled prospects on which such members perform technical work. The size
of the grant will be discretionary, designed to reward such employees with
incentive compensation based on the results of the oil and gas drilling
activities conducted by the Company. The Company currently does not expect such
interests in the aggregate to exceed three percent of the Company's net revenue
interest in such prospects.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
The Company will establish a Compensation Committee consisting solely of
nonemployee directors effective upon closing of the Offering. In the past,
matters with respect to the compensation of executive officers of the Company
were determined by the members of the Board of Directors, as a whole.
 
                              CERTAIN TRANSACTIONS
 
STRATUM
 
In April 1996, Araxas entered into the Stratum debt agreement pursuant to which
it borrowed a total of $26 million. The Stratum debt agreement was repaid in
full and terminated upon the consummation of the Combination Transaction with
the proceeds from the Bridge Loan. In connection with the Stratum debt
agreement, Araxas granted to Stratum an option to acquire common stock of
Araxas. In connection with the Combination Transaction, XPLOR assumed Araxas's
obligations under the option agreement. Stratum has an option to purchase (the
"Stratum Option")     shares of common stock (the "Stratum Option Shares") at
an exercise price of $    per share. The Stratum Option is currently
exercisable and expires on June 30, 1999. In addition, Stratum has certain
registration rights associated with the Stratum Option Shares. See "--
Registration Rights Agreements."
 
The terms of the Stratum debt agreement also required Araxas to grant to
Stratum overriding royalty interests in exploratory properties drilled or
purchased using funds borrowed from Stratum. During the term of the Stratum
debt agreement, Araxas granted to Stratum overriding royalty interests of up to
5.5% of Araxas's interest in certain of its exploratory and development
properties. In connection with the termination of the Stratum debt agreement,
the Company agreed to grant to Stratum overriding royalty interests of up to 4%
of the Company's interests in certain additional exploratory prospects. As a
result, Stratum holds overriding royalty interests on substantially all of the
Company's properties acquired from Araxas. In the event that any prospects in
which Stratum has an overriding royalty interest are sold by the Company prior
to drilling a test well, Stratum's right to receive an overriding royalty
interest will convert into a right to receive a proportionate share of the net
proceeds from such a sale.
 
NEW WEST
 
In 1995, Araxas acquired certain properties in West Texas and along the Texas
Gulf Coast, including the Adams-Baggett field, from New West in exchange for
25,000 shares of Araxas common stock, redeemable preferred stock with an
aggregate redemption value of $1.5 million and a promissory note in the
principal amount of $3.7 million. In March 1996, Araxas issued to New West
5,263 additional shares of Araxas common stock to amend certain provisions of
the note, including reducing the outstanding principal amount to $3.4 million.
Araxas repaid the note in full from borrowings under the Stratum debt
agreement. Araxas also redeemed the redeemable preferred stock held by New West
for 7,434 additional shares of Araxas common stock. In the Combination
Transaction, New West received approximately      shares of Common Stock in
exchange for its shares of Araxas common stock.

<PAGE>
 
CREDIT LYONNAIS
 
In connection with the Bridge Loan, the Company issued to Credit Lyonnais a
warrant (the "Warrant") to purchase a number of shares of Common Stock equal to
5% of the number of shares of Common Stock sold by the Company in this
Offering, including any shares sold by the Company pursuant to the over-
allotment option (    shares), at an exercise price per share equal to 125% of
the initial public offering price per share set forth on the cover page of this
Prospectus. Both the number of shares of Common Stock subject to the Warrant
and the exercise price thereof are subject to adjustment upon the occurrence of
a subdivision or combination of outstanding shares of Common Stock or a
dividend payable in shares of Common Stock. In addition, upon a reorganization,
reclassification, consolidation, merger or sale with respect to the Company in
which the holders of Common Stock receive stock, securities or assets in
exchange for Common Stock, the Company has agreed to make appropriate
provisions to ensure that the holder of the Warrant will receive in lieu of
Common Stock acquirable upon exercise of the Warrant such shares of stock,
securities or assets as may be payable or issued with respect to the number of
shares of Common Stock immediately theretofore acquirable upon exercise of the
Warrant. The Warrant is exercisable, in whole or in part, at any time after the
closing of the Offering up to and including the second anniversary date
thereof. Credit Lyonnais also has certain registration rights relating to the
Common Stock acquired upon exercise of the Warrant. See "--Registration Rights
Agreements."
 
OTHER
 
Pursuant to the acquisition agreement for the Combination Transaction, Mr.
Rowsey, Mr. Nance, New West, Stratum (only in the event that Stratum exercises
the Stratum Option) and the other former shareholders of Araxas have certain
rights to acquire additional shares of Common Stock upon payment of par value
(or, in certain cases, additional consideration). The acquisition agreement for
the Combination Transaction provides that, in the event (i) any shares of
restricted Common Stock issued to Mr. Nance are forfeited or otherwise
reacquired by the Company, (ii) any shares of Common Stock issued to GR, Inc.
in connection with the acquisition of Main Pass 35 and Gulfland Industries are
reacquired by the Company or (iii) the Stratum Option expires without being
exercised, then the former shareholders of Araxas who became shareholders of
Araxas prior to the issuance of the forfeited or reacquired stock or the
granting of the Stratum Option, as applicable, who are holders of Common Stock
at the time of such forfeiture or reacquistion shall be entitled, as a group,
to acquire for the aggregate par value thereof (plus any additional
consideration paid by the Company for such reacquisition or the exercise price
of the Stratum Option) such reacquired shares of Common Stock.
 
In connection with the Combination Transaction, the Company issued a $1.0
million promissory note to each of Messrs. Krenzke, Davis and Duggan, which
notes are secured by a lien on all of the capital stock of INEXS. See "The
Combination Transaction."
 
Effective September 30, 1997, the Company acquired the capital stock and
certain assets of FO&G from Mr. Faulkinberry for $750,000 in cash and a
promissory note in the principal amount of $2.2 million. The assets acquired
included, among other things, the working interests and overriding royalty
interests held by Mr. Faulkinberry that were granted by the Company in
prospects generated and developed by the Company. In addition, the Company has
entered into a severance agreement with Mr. Faulkinberry pursuant to which the
Company paid him $50,000, less taxes.
 
At the beginning of 1994, the Company owed Mr. Rowsey approximately $455,000
from advances he had made to the Company in 1993. This amount was repaid during
1994, primarily in the form of an allocation for tax purposes of property costs
to Mr. Rowsey, together with some cash. In connection with Mr. Rowsey's
becoming a nonemployee director of the Company, the Company issued to Mr.
Rowsey a promissory note in the principal amount of $1.0 million, which bears
no interest and will mature upon the closing of the Offering.

REGISTRATION RIGHTS AGREEMENTS
 
Stratum
 
In connection with the Stratum debt agreement, the Company has agreed that,
upon the request of Stratum, it will file a registration statement under the
Securities Act to register all or a portion of the Stratum Option Shares. The
Company is obligated to effect one such registration. The Company is entitled
to postpone any such registration for up to three months in order to complete
any merger, consolidation, transfer or similar transaction that is in process
at the time such demand is made. In addition, subject to certain conditions and
limitations, Stratum may participate in any registration by the Company
(including any registration effected by the Company for stockholders other than
Stratum and including any shelf registration) of any of its Common Stock. The
Company is not obligated to effect any such registration unless Stratum has
exercised its option with respect to the Stratum Option Shares. The Company is
not obligated to register any Stratum Option Shares if all of the Stratum
Option Shares proposed to be registered may be sold without restriction to the
public without registration under the Securities Act. Stratum's registration
rights are not assignable without the consent of the Company.
 
Equitable
 
In connection with the Combination Transaction, the Company entered into a
registration rights agreement with Equitable. The agreement provides that, upon
the request of Equitable or any transferee stockholder (collectively, the
"Equitable Holders") holding an aggregate of a majority of the Common Stock
subject to the agreement (the "Registrable Securities"), the Company will file
a shelf registration statement under the Securities Act to register the
Registrable Securities held by any Equitable Holder that desires to sell
Registrable Securities pursuant to such registration statement. The Company is
obligated to effect one such registration. Such request may be made only after
the closing of the Offering. The Company will not be required to effect such a
registration if, among other things, during a reasonable period of time not to
exceed six months following the closing of the Offering, the representatives of
the Underwriters advise the Company that such a registration would adversely
affect the market for the Common Stock. In addition, subject to certain
conditions and limitations, the agreement provides that any Equitable Holder
may participate in any registration by the Company (including any registration
effected by the Company for stockholders other than Equitable Holders) of any
of its Common Stock. The registration rights covered by the agreement may be
assigned without the consent of the Company. A Registrable Security ceases to
be subject to the agreement when (i) it has been effectively registered under
the Securities Act and disposed of in accordance with the registration
statement covering it, (ii) it is sold pursuant to Rule 144 or Rule 145 under
the Securities Act or (iii) it is eligible for sale pursuant to Rule 144 or
Rule 145 without volume limitations. An aggregate of     outstanding shares of
Common Stock are subject to the agreement.
 
Credit Lyonnais
 
In connection with the Bridge Loan, the Company entered into a registration
rights agreement with Credit Lyonnais. The agreement provides that, if Credit
Lyonnais requests the Company to file a registration statement under the
Securities Act registering all or part, but not less than 75%, of the total
number of shares of Common Stock that may be acquired through the exercise of
the Warrant (the "Warrant Securities"), the Company will file a shelf
registration statement to register all Warrant Securities that Credit Lyonnais
desires to sell pursuant to such registration statement. The Company is
obligated to effect one such registration. Such request may be made only after
the closing of the Offering. The Company will not be required to effect such a
registration if, among other things, during a reasonable period of time not to
exceed six months following the closing of the Offering, the representatives of
the Underwriters advise the Company that such a registration would adversely
affect the market for the Common Stock. In addition, subject to certain
conditions and limitations, the agreement provides that Credit Lyonnais may
participate in any registration by the Company (including any registration
effected by the Company for stockholders other than Credit Lyonnais) of any of
its Common Stock. The registration rights covered by the agreement may be
assigned without the consent of the Company. A Warrant Security ceases to be
subject to the agreement when (i) it has been effectively registered under the
Securities Act and disposed of in accordance with the registration statement
covering it, (ii) it is sold pursuant to Rule 144 or Rule 145 under the
 
                                       63
<PAGE>
 
Securities Act or (iii) it is eligible for sale pursuant to Rule 144 or Rule
145 without volume limitations. An aggregate of    outstanding shares of Common
Stock are subject to the agreement.
 
Weisser
 
Prior to the Combination Transaction, South Coast entered into a registration
rights agreement with Equitable, Messrs. Krenzke, Davis and Duggan, and
Weisser, Johnson & Co. ("Weisser"). In the Combination Transaction, the
registration rights of Equitable and Messrs. Krenzke, Davis and Duggan granted
pursuant to this agreement were terminated. Weisser's registration rights
relate to approximately     shares of Common Stock that may be acquired by
Weisser from Messrs. Krenzke, Davis and Duggan upon exercise of an option
granted to Weisser by such persons (when so acquired, the "Weisser Option
Shares"). The agreement provides that, upon the request of the holders of a
majority of the Weisser Option Shares (collectively, the "Weisser Holders"),
the Company will file a registration statement under the Securities Act to
register the Weisser Option Shares held by any Weisser Holder that desires to
sell Registrable Securities pursuant to such registration statement. The
Weisser Holders may make unlimited requests for registration provided that such
registration include at least 25% of the Weisser Option Shares. The first such
request may not be made for a period beginning six months following the closing
of the Offering and ending on the earliest to occur of, among other things, (x)
the second anniversary of the beginning of the period and (y) the date on which
Equitable ceases to own at least     shares of Common Stock. In addition,
subject to certain conditions and limitations, the agreement provides that a
Weisser Holder may participate in any registration by the Company of any of its
Common Stock. A Weisser Option Share ceases to be subject to the agreement when
it has been (i) effectively registered under the Securities Act and disposed of
in accordance with the registration statement covering it or (ii) sold pursuant
to Rule 144 under the Securities Act.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
Upon consummation of the Offering, approximately     shares of Common Stock
will be outstanding. The     shares of Common Stock sold in the Offering will
be registered under the Securities Act and will be freely tradeable without
restriction or further registration under the Securities Act, except for
certain manner of sale, volume limitations and other restrictions with respect
to any shares purchased in the Offering by an affiliate of the Company (a
"Company Affiliate"), which will be subject to the resale limitations of Rule
144 (not including the holding period requirement). Under Rule 144 a person is
an affiliate of an entity if such person directly or indirectly controls or is
controlled by or is under common control with such entity and may include
certain officers and directors, principal stockholders and certain other
stockholders with special relationships. All of the remaining     shares that
will be outstanding following the Offering will be owned by officers and
directors of the Company and other persons receiving shares in the Combination
Transaction and will constitute "restricted securities" within the meaning of
Rule 144. Such shares may not be resold in a public distribution except
pursuant to an effective registration statement under the Securities Act or an
applicable exemption from registration, including pursuant to Rule 144. The
Company has entered into registration rights agreements with certain Company
Affiliates who own approximately     shares of Common Stock and options to
purchase     shares of Common Stock, pursuant to which such persons have
received demand and piggyback registration rights that provide for the
registration of the resale of such shares at the Company's expense. See
"Certain Transactions." This Prospectus, however, may not be used in connection
with any resale of shares of Common Stock acquired in the Offering by Company
Affiliates or in the Combination Transaction.
 
In general, under Rule 144 as currently in effect, if a minimum of one year has
elapsed since the later of the date of acquisition of the restricted securities
from the issuer or from an affiliate of the issuer, a person (or persons whose
shares of Common Stock are aggregated), including persons who may be deemed
Company Affiliates, would be entitled to sell within any three-month period a
number of shares of Common Stock that does not exceed the greater of (i) one
percent of the then-outstanding shares of Common Stock (i.e., approximately
shares immediately after consummation of the Offering) or (ii) the average
weekly trading volume during the four calendar weeks preceding the date on
which notice of the sale is filed with the Commission. Sales under Rule 144 are
also subject to certain provisions as to the manner of sale (which provision is
proposed to be eliminated), notice requirements and the availability of current
public information about the Company. In addition, under Rule 144(k), if a
period of at least two years has elapsed since the later of the date restricted
securities were acquired from the Company or the date they were acquired from a
Company Affiliate, a shareholder who is not a Company Affiliate at the time of
sale and who has not been a Company Affiliate for at least three months prior
to the sale would be entitled to sell shares of Common Stock in the public
market immediately without compliance with the foregoing requirements under
Rule 144. Rule 144 does not require the same person to have held the securities
for the applicable periods. The foregoing summary of Rule 144 is not intended
to be a complete description thereof.
 
The Company currently has outstanding options (     of which are vested) and
warrants to purchase     shares of Common Stock. Such shares for which the
vested portion of outstanding options may be exercised may generally be sold by
employees, officers, directors or consultants and independent contractors of
the Company in reliance on the resale provisions of Rule 701. In general, such
persons who purchased shares pursuant to a written compensatory plan or
contract entered into prior to the Offering is entitled to rely on the resale
provisions of Rule 701, which permit nonaffiliates to sell their Rule 701
shares without having to comply with the public information, holding period,
volume limitation or notice provisions of Rule 144, and permit affiliates to
sell their Rule 701 shares without having to comply with the Rule 144 holding
period restrictions, in each case commencing 90 days after the date of this
Prospectus. The holders of vested outstanding options to purchase     shares
could exercise these options and could then sell such shares in compliance with
Rule 701. Holders of all options and warrants granted prior to the Offering
have agreed not to sell the shares of Common Stock related to such options and
warrants for a period of 180 days following the date of this Prospectus.
 
The Company intends to file a registration statement on Form S-8 under the
Securities Act to register the shares of Common Stock reserved or to be
available for issuance pursuant to the Incentive Plan. Shares of Common Stock
issued pursuant to such plan generally will be available for sale in the open
market by holders who are not
 
                                       67
<PAGE>
 
Company Affiliates and, subject to the volume and other limitations of Rule
144, by holders who are Company Affiliates.
 
The Company, substantially all of its existing stockholders, Stratum and each
of the Company's officers and directors have agreed, with certain limited
exceptions, that they will not (i) offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase or otherwise transfer or dispose
of, directly or indirectly, any shares of Common Stock, any options for the
sale of Common Stock, or any securities convertible into or exercisable or
exchangeable for Common Stock, or (ii) enter into any swap or other agreement
that transfers, in whole or in part, any of the economic consequences of
ownership of Common Stock for a period of 180 days after the date of this
Prospectus, without the prior written consent of J.P. Morgan Securities Inc.
See "Underwriting."
 
Prior to the Offering, there has been no public market for the Common Stock,
and no prediction can be made of the effect, if any, that sales of Common Stock
or the availability of shares for sale will have on the market price prevailing
from time to time. Following the Offering, sales of substantial amounts of
Common Stock in the public market or otherwise, or the perception that such
sales could occur, could adversely affect the prevailing market price for the
Common Stock.
 
                          DESCRIPTION OF CAPITAL STOCK
 
The Company's authorized capital stock consists of     shares of Common Stock
and     shares of preferred stock, $.001 par value per share ("Preferred
Stock"). Following consummation of the Offering, there will be approximately
    shares of Common Stock outstanding (assuming the over-allotment option is
not exercised), and no shares of Preferred Stock will be outstanding. The
following summary does not purport to be complete, and reference is made to the
more detailed provisions of the Company's Certificate of Incorporation (the
"Certificate of Incorporation") and Bylaws, which are filed as exhibits to the
registration statement of which this Prospectus is a part.
 
COMMON STOCK
 
The Common Stock possesses ordinary voting rights for the election of directors
and in respect of other corporate matters, each share being entitled to one
vote. There are no cumulative voting rights, meaning that the holders of a
majority of the shares voting for the election of directors can elect all the
directors if they choose to do so. The Common Stock carries no preemptive
rights and is not convertible, redeemable or assessable, or entitled to the
benefits of any sinking fund. The holders of Common Stock are entitled to
dividends in such amounts and at such times as may be declared by the Board of
Directors out of funds legally available therefor. See "Dividend Policy" for
information regarding dividend policy.
 
PREFERRED STOCK
 
The Board of Directors of the Company is empowered, without approval of the
stockholders, to cause shares of Preferred Stock to be issued in one or more
series, with the numbers of shares of each series to be determined by it. The
Board of Directors is authorized to fix and determine the powers, designations,
preferences and relative, participating, optional or other rights (including,
without limitation, voting powers, full or limited, preferential rights to
receive dividends or assets upon liquidation, rights of conversion or exchange
into Common Stock, Preferred Stock of any series or other securities,
redemption provisions and sinking fund provisions) between series and between
the Preferred Stock or any series thereof and the Common Stock, and the
qualifications, limitations or restrictions of such rights.
 
The Company has no present intention to issue shares of Preferred Stock after
consummation of the Offering. Nevertheless, the issuance of shares of Preferred
Stock, or the issuance of rights to purchase such shares, could be used to
discourage an unsolicited acquisition proposal. For instance, the issuance of a
series of Preferred Stock may impede a business combination by including class
voting rights that would enable the holders to block such a
 
                                       68
<PAGE>
 
transaction; or such issuance might facilitate a business combination by
including voting rights that would provide a required percentage vote of the
stockholders. In addition, under certain circumstances, the issuance of
Preferred Stock could adversely affect the voting power of the holders of the
Common Stock. Although the Board of Directors is required to make any
determination to issue such stock based on its judgment as to the best
interests of the stockholders of the Company, the Board of Directors could act
in a manner that would discourage an acquisition attempt or other transaction
that some or even a majority of the stockholders might believe to be in their
best interests or in which stockholders might receive a premium for their stock
over the then market price of such stock. The Board of Directors does not at
present intend to seek stockholder approval prior to any issuance of currently
authorized stock, unless otherwise required by law or the rules of any market
on which the Company's securities are traded.
 
OTHER MATTERS
 
Delaware law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors' fiduciary duty of care. The duty of care
requires that, when acting on behalf of the corporation, directors must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations authorized by Delaware
law, directors are accountable to corporations and their stockholders for
monetary damages for conduct constituting gross negligence in the exercise of
their duty of care. Delaware law enables corporations to limit available relief
to equitable remedies such as injunction or rescission. The Certificate of
Incorporation limits the liability of directors of the Company to the Company
or its stockholders to the fullest extent permitted by Delaware law.
Specifically, directors of the Company will not be personally liable for
monetary damages for breach of a director's fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to
the Company or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
for unlawful payments of dividends or unlawful stock repurchases or redemptions
as provided in Section 174 of the Delaware General Corporation Law or (iv) for
any transaction from which the director derived an improper personal benefit.
 
The inclusion of this provision in the Certificate of Incorporation may have
the effect of reducing the likelihood of derivative litigation against
directors, and may discourage or deter stockholders or management from bringing
a lawsuit against directors for breach of their duty of care, even though such
an action, if successful, might otherwise have benefited the Company and its
stockholders. The Company's Bylaws provide indemnification to the Company's
officers and directors and certain other persons with respect to certain
matters, and the Company has entered into agreements with each of its directors
providing for indemnification with respect to certain matters.
 
The Certificate of Incorporation provides that stockholders may act only at an
annual or special meeting of stockholders and may not act by written consent.
The Bylaws provide that special meetings of the stockholders can be called only
by a majority of the Board of Directors of the Company.
 
Pursuant to the Certificate of Incorporation, certain transactions involving,
among other persons, any person who is a beneficial owner of 10% or more of the
aggregate voting power of all outstanding stock of the Company (a "related
person") require the affirmative vote of the holders of both (i) at least 80%
of the outstanding voting stock and (ii) at least 66% of the outstanding voting
stock not beneficially owned by the related person. Transactions subject to
such approval include certain mergers or consolidations of the Company or sales
or transfers of assets and properties having an aggregate fair market value of
$10.0 million or more.
 
The Certificate of Incorporation provides that the Board of Directors shall
consist of three classes of directors serving for staggered three-year terms.
As a result, approximately one-third of the Company's Board of Directors will
be elected each year. The classified board provision could prevent a party who
acquires control of a majority of the outstanding voting stock of the Company
from obtaining control of the Board of Directors until the second annual
stockholders' meeting following the date the acquiror obtains the controlling
interest. See "Management."
 
 
                                       69
<PAGE>
 
The Certificate of Incorporation provides that the number of directors will be
no greater than 12 nor less than 3. The Certificate of Incorporation further
provides that directors may be removed only for cause (as defined in the
Certificate of Incorporation), and then only by the affirmative vote of the
holders of at least a majority of all outstanding voting stock entitled to
vote. This provision, in conjunction with the provisions of the Certificate of
Incorporation authorizing the Board of Directors to fill vacant directorships,
will prevent stockholders from removing incumbent directors without cause and
filling the resulting vacancies with their own nominees. In addition, the
Bylaws provide that the Compensation Committee will consist solely of members
who are not employees of the Company and the Audit Committee will include at
least a majority of members who are not employees of the Company.
 
The Company is a Delaware corporation and is subject to Section 203 of the
Delaware General Corporation Law. In general, Section 203 prevents an
"interested stockholder" (defined generally as a person owning 15% or more of a
corporation's outstanding voting stock) from engaging in a "business
combination" (as defined) with a Delaware corporation for three years following
the date such person became an interested stockholder unless (i) before such
person became an interested stockholder, the board of directors of the
corporation approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (ii) upon
consummation of the transaction that resulted in the interested stockholder's
becoming an interested stockholder, the interested stockholder owned at least
85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding stock held by directors who are also officers
of the corporation and by employee stock plans that do not provide employees
with the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer); or (iii) following the
transaction in which such person became an interested stockholder, the business
combination was approved by the board of directors of the corporation and
authorized at a meeting of stockholders by the affirmative vote of the holders
of two-thirds of the outstanding voting stock of the corporation not owned by
the interested stockholder. Under Section 203, the restrictions described above
also do not apply to certain business combinations proposed by an interested
stockholder following the announcement or notification of one of certain
extraordinary transactions involving the corporation and a person who had not
been an interested stockholder during the previous three years or who became an
interested stockholder with the approval of a majority of the corporation's
directors, if such extraordinary transaction is approved or not opposed by a
majority of the directors who were directors prior to any person's becoming an
interested stockholder during the previous three years or were recommended for
election or elected to succeed such directors by a majority of such directors.
 
STOCKHOLDER PROPOSALS
 
The Company's Bylaws contain provisions requiring that advance notice be
delivered to the Company of any business to be brought by a stockholder before
an annual meeting of stockholders, and providing for certain procedures to be
followed by stockholders in nominating persons for election to the Board of
Directors of the Company. Generally, such advance notice provisions provide
that written notice must be given to the Secretary of the Company by a
stockholder (i) in the event of business to be brought by a stockholder before
an annual meeting, not less than 90 days prior to the anniversary date of the
immediately preceding annual meeting of stockholders of the Company (with
certain exceptions if the date of the annual meeting is different by more than
specified amounts from the anniversary date) and (ii) in the event of
nominations of persons for election to the Board of Directors by any
stockholder, (a) with respect to an election to be held at the annual meeting
of stockholders, not less than 90 days prior to the anniversary date of the
immediately preceding annual meeting of stockholders of the Company (with
certain exceptions if the date of the annual meeting is different by more than
specified amounts from the anniversary date) and (b) with respect to an
election to be held at a special meeting of stockholders for the election of
directors, not later than the close of business on the tenth day following the
day on which notice of the date of the special meeting was mailed to
stockholders or public disclosure of the date of the special meeting was made,
whichever first occurs. Such notice must set forth specific information
regarding such stockholder and such business or director nominee, as described
in the Company's Bylaws.

The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase shares of Common Stock are subject to the approval of
certain legal matters by counsel and certain other conditions. Under the terms
and conditions of the Underwriting Agreement, the Underwriters are obligated to
take and pay for all such shares of Common Stock, if any are taken. Under
certain circumstances, the commitments of non-defaulting Underwriters may be
increased as set forth in the Underwriting Agreement.
 
The Underwriters propose initially to offer the shares of Common Stock directly
to the public at the public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in excess
of $    per share. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of $    per share to certain other dealers. After the
initial public offering of the Common Stock, the public offering price and such
concession may be changed.
 
The Company and the Selling Stockholders have granted to the Underwriters an
option, expiring at the close of business on the 30th day after the date of
this Prospectus, to purchase, in the aggregate, up to     additional shares of
Common Stock, at the initial public offering price, less the underwriting
discount. The Underwriters may exercise such option solely for the purpose of
covering over-allotments, if any. To the extent that the Underwriters exercise
their option, each Underwriter will have a firm commitment, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number set forth next to such Underwriter's name in the preceding
table bears to the total number of shares of Common Stock initially offered
hereby.
 
The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments the Underwriters may be required
to make in respect thereof.
 
The Company, substantially all of its existing stockholders, Stratum and each
of the Company's officers and directors have agreed that they will not (i)
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of, directly or indirectly, any
shares of Common Stock, any options for the sale of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock, or
(ii) enter into any swap or other agreement that transfers, in whole or in
part, any of the economic consequences of ownership of Common Stock, for a
period of 180 days after the date of this Prospectus, without the prior written
consent of J.P. Morgan Securities Inc., other than the Common Stock to be sold
in the Offering and any shares of Common Stock issued upon the exercise of
options granted under existing employee stock option plans. J.P. Morgan
Securities Inc. may provide such written consent without notice to the
Company's stockholders or the Nasdaq National Market.

The Company intends to pay Credit Lyonnais approximately $    million of the
net proceeds from the Offering to repay the Bridge Loan. See "Use of Proceeds."
Credit Lyonnais is an affiliate of Credit Lyonnais Securities (USA) Inc., a
member of the National Association of Securities Dealers, Inc. ("NASD"),
participating in the distribution of the Offering. The Offering is therefore
being conducted in accordance with Rule 2710(c)(8) of the NASD's Conduct Rules,
and the price at which the Common Stock will be distributed to the public will
be established pursuant to Rule 2720(c)(3) of the Conduct Rules. J.P. Morgan
Securities Inc. is acting as a "qualified independent underwriter" within the
meaning of such rules and is assuming the responsibilities of acting as such in
pricing the Offering and conducting due diligence. J.P. Morgan Securities Inc.
will receive no separate fee for its services as qualified independent
underwriter.
 
Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price for the shares of Common Stock offered hereby
has been determined by agreement between the Company and the Underwriters.
Among the factors considered in making such determination were the history of
and the prospects for the industry in which the Company competes, current and
historical oil and gas prices, an assessment of the Company's management, the
present operations of the Company, the historical results of operations of the
Company and the trend of its revenues and earnings, the prospects for future
earnings of the Company, the general condition of the securities markets at the
time of the Offering and the prices of similar securities of generally
comparable companies.
 
To facilitate the offering of the Common Stock, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may over-allot in connection with
the Offering, creating a short position in the Common Stock for their own
account. In addition, to cover over-allotments or to stabilize the price of the
Common Stock, the Underwriters may bid for, and purchase, shares of Common
Stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
Common Stock in the Offering, if the syndicate repurchases previously
distributed Common Stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the Common Stock above independent market
levels. The Underwriters are not required to engage in these activities and may
end any of these activities at any time.
 
The Company has applied for quotation of the Common Stock on the Nasdaq
National Market under the symbol "XPLR." There can be no assurance that an
active trading market will develop for the Common Stock or that the Common
Stock will trade in the public market subsequent to the Offering at or above
the initial public offering price.
 
At the Company's request, the Underwriters have reserved     shares of Common
Stock for sale at the initial public offering price to the Company's employees
and other persons having business relationships with the Company.
 
The Representatives have informed the Company that the Underwriters do not
expect sales to accounts over which the Underwriters exercise discretionary
authority to exceed 5% of the total number of shares of Common Stock offered by
them.

                       GLOSSARY OF CERTAIN INDUSTRY TERMS
 
The definitions set forth below shall apply to the indicated terms as used in
this Prospectus. All volumes of gas referred to herein are stated at the legal
pressure base of the state or area where the reserves exist and at 60 degrees
Fahrenheit and in most instances are rounded to the nearest major multiple.
 
 
"Bbl"                    One stock tank barrel, or 42 U.S. gallons liquid
                         volume, used herein in reference to crude oil or
                         other liquid hydrocarbons.
 
"Bcf"                    Billion cubic feet.
 
"Bcfe"                   Billion cubic feet equivalent, determined using the
                         ratio of six Mcf of gas to one Bbl of crude oil,
                         condensate or gas liquids.
 
"BOE"                    Barrels of oil equivalent, determined using the ratio
                         of six Mcf of gas to one Bbl of crude oil, condensate
                         or gas liquids.
 
"Btu" or "British 
Thermal Unit"            The quantity of heat required to raise the
                         temperature of one pound of water by one degree
                         Fahrenheit.
 
"Development well"       A well drilled within the proved area of an oil or
                         gas reservoir to the depth of a stratigraphic horizon
                         known to be productive.
 
"Exploratory well"       A well drilled to find and produce oil or gas
                         reserves not classified as proved, to find a new
                         reservoir in a field previously found to be
                         productive of oil or gas in another reservoir or to
                         extend a known reservoir.
 
"Farm-in" or "farm-out"  An agreement whereunder the owner of a working
                         interest in an oil and gas lease assigns the working
                         interest or a portion thereof to another party who
                         desires to drill on the leased acreage. Generally,
                         the assignee is required to drill one or more wells
                         in order to earn its interest in the acreage. The
                         assignor usually retains a royalty or reversionary
                         interest in the lease. The interest received by an
                         assignee is a "farm-in" while the interest

"Field"                  An area consisting of a single reservoir or multiple
                         reservoirs all grouped on or related to the same
                         individual geological structural feature and/or
                         stratigraphic condition.
 
"Finding costs"          Costs associated with acquiring and developing proved
                         oil and gas reserves which are capitalized by the
                         Company pursuant to generally accepted accounting
                         principles, including all costs involved in acquiring
                         acreage, geological and geophysical work and the cost
                         of drilling and completing wells.
 
"Gross acres" or "gross 
wells"                   The total acres or wells, as the case may be, in
                         which a working interest is owned.

"Mcfe"
                         One thousand cubic feet equivalent, determined using
                         the ratio of six Mcf of gas to one Bbl of crude oil,
                         condensate or gas liquids.
 
"MMBbls"
                         One million barrels of crude oil or other liquid
                         hydrocarbons.
 
"MMBtus"
                         One million British Thermal Units.
 
                                       75
<PAGE>
 
"MMcf"                   One million cubic feet.
 
"MMcfe"                  One million cubic feet equivalent, determined using
                         the ratio of six Mcf of gas to one Bbl of crude oil,
                         condensate or gas liquids, which approximates the
                         relative energy content of crude oil, condensate and
                         gas liquids as compared to gas. Prices have
                         historically been higher or substantially higher for
                         crude oil than gas on an energy equivalent basis.
 
"Overriding royalty 
interest"                A royalty interest that is carved out of a lessee's

                         production expenses and taxes.
 
"Project"                A defined geographic area in which one or more
                         prospects have been identified and selected for data
                         acquisition, evaluation or drilling.
 
"Prospect"               A hydrocarbon-bearing or potentially hydrocarbon-
                         bearing feature identified through analysis of
                         engineering, geological and geophysical data.

"Proved reserves"        The estimated quantities of crude oil, gas and gas
                         liquids that geological and engineering data
                         demonstrate with reasonable certainty to be
                         recoverable in future years from known reservoirs
                         under existing economic and operating conditions.
 
"Proved undeveloped 
location"                A site on which a development well can be drilled
                         consistent with spacing rules for purposes of

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

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
 
                  DECEMBER 31, 1995 AND 1996 AND JUNE 30, 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES
 
Organization
 
The consolidated financial statements include the accounts of Araxas Energy
Corporation (AEC) and its wholly-owned subsidiaries, Araxas Exploration, Inc.
(AEI), Araxas SPV-1 (SPV) and Gulfland Industries, Inc. (GII), collectively
referred to as the Company. All significant intercompany balances and
transactions have been eliminated in consolidation.
 
The Company conducts oil and gas exploration, drilling and development
operations along the Texas and Louisiana Gulf Coasts and in Alabama. Prior to
its divestiture in April 1997, GII provided contract operating services to the
Company and third parties in the Gulf of Mexico.
 
Revenue Recognition
 
Owners of oil and gas properties often take more or less production from a
property than entitled to based on their ownership percentages in the property,
which results in a condition known in the industry as a production imbalance.
The Company follows the sales method of accounting for production imbalances.
Under this method, the Company recognizes revenues on production as it is taken
and delivered to its purchasers. The Company's oil and gas imbalances were not
significant at December 31, 1995 and 1996.
 
Cash and Cash Equivalents
 
The Company considers all highly liquid investments with an original maturity
of less than ninety days to be cash and cash equivalents.
 
Investment Securities
 
The Company classifies its debt and equity securities in one of three
categories: trading, available-for-sale, or held-to-maturity. Trading
securities are bought and held principally for the purpose of selling them in
the near term. Held-to-maturity securities are those securities in which the
Company has the ability and intent to hold until maturity. All other securities
not included in the trading or held-to-maturity categories are classified as
available-for-sale.
 
Trading and available-for-sale securities are recorded at fair value. Held-to-
maturity securities are recorded at amortized cost, adjusted for the
amortization or accretion of premiums or discounts. Unrealized holding gains
and losses on trading securities are included in earnings. Unrealized holding
gains and losses, net of the related tax effect, on available-for-sale
securities are excluded from earnings and are reported as a separate component
of stockholders' equity until realized. Realized gains and losses from the sale
of available-for-sale securities are determined on a specific identification
basis.
 
A decline in the market value of any available-for-sale or held-to-maturity
security below cost that is deemed to be other than temporary results in a
reduction in carrying amount to fair value. The impairment is charged to
earnings and a new cost basis for the security is established. Premiums and
discounts are amortized or accreted over the life of the related held-to-
maturity security as an adjustment to yield using the effective interest
method. Dividend and interest income are recognized when earned.
 
Property and Equipment
 
The Company follows the full cost method of accounting for oil and gas
properties, whereby all productive and nonproductive property acquisition,
exploration and development costs are capitalized. Such capitalized costs
 
                                      F-7
<PAGE>
 
                           ARAXAS ENERGY CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
include lease acquisition costs, delay rentals, geophysical, geological and
other costs, drilling, completion and other related costs and direct general
and administrative expenses associated with property acquisition, exploration
and development activities. Capitalized general and administrative costs
include internal costs such as salaries and related benefits paid to employees
to the extent that they are directly engaged in such activities, as well as all
other directly identifiable general and administrative costs associated with
such activities, and do not include any costs related to production, general
corporate overhead, or similar activities. Capitalized internal general and
administrative costs were $462,000 in 1994, $187,000 in 1995 and $857,000 in
1996.
 
All capitalized costs of oil and gas properties and estimated future
development and dismantlement costs are amortized using the unit-of-production
method based on the ratio of current production to total proved recoverable oil
and natural gas reserves. Investment in unproved properties and major
development projects are not amortized until proved reserves associated with
the projects can be determined or until impairment occurs. Unevaluated costs of
$58,000 and $933,000 were excluded from amortization at December 31, 1995 and
1996, respectively. Unevaluated properties are assessed quarterly to determine
whether any impairment has occurred. If the results of an assessment indicate
that the properties are impaired, the amount of the impairment is added to the
capitalized cost to be amortized. Abandonments of properties are accounted for
as adjustments to capitalized costs with no loss recognized.
 
Depreciation, depletion and amortization expense per equivalent thousand cubic
feet of production was $0.79 in 1994, $0.78 in 1995 and $0.65 in 1996.
 
In accordance with the full cost method of accounting, the net capitalized
costs of oil and gas properties less related deferred income taxes for each
cost center are limited to the sum of the estimated future net revenues from
the properties at current prices less estimated future expenditures, discounted
at 10%, and unevaluated costs not being amortized, less income tax effects
related to differences between the financial and tax bases of the properties,
computed on a quarterly basis.
 
Depletion expense and limits to capitalized costs are based on estimates of oil
and gas reserves which are inherently imprecise and assume current prices for
future net revenues. Accordingly, it is reasonably possible that the estimates
of reserves quantities and future net revenues could differ materially in the
near term from amounts currently estimated.
 
Gains and losses on sales of oil and gas properties are not recognized in
income unless the sale involves a significant portion of the reserves. A gain
of $1,319,997 was recorded in 1994.
 
All other property and equipment are stated at original cost. Depreciation on
other property and equipment is calculated on the straight-line method over the
estimated useful lives of the assets which range from 5 to 15 years.
 
Dismantlement, Restoration and Environmental Costs
 
The estimated costs, net of salvage value, of dismantling facilities and site
remediation on projects with limited lives or facilities that are required to
be dismantled by contract, regulation or law, and the estimated costs of
restoration and reclamation of land associated with such projects are accrued
on a unit-of-production basis during operations. Such costs are included in
depreciation, depletion and amortization charges in the current period.
 
The Company is subject to extensive federal, state and local environmental laws
and regulations. These laws, which are constantly changing, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release or
petroleum or chemical

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
substances at various sites. Environmental expenditures are expensed or
capitalized depending on their future economic benefit. Expenditures that
relate to an existing condition caused by past operations and that have no
future economic benefits are expensed. Liabilities for expenditures of a
noncapital nature are recorded when environmental assessment and/or remediation
is probable, and the costs can be reasonably estimated.
 
Impairment of Long-Lived Asset and Long-Lived Assets to Be Disposed Of
 
The Company adopted the provisions of Statement of Financial Accounting
Standards (SFAS) No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of, on January 1, 1996. This Statement
requires that long-lived assets, other than oil and gas properties under the
full cost method, and certain identifiable intangibles be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset not be recoverable. Recoverability of assets to be
held and used is measured by a comparison of the carrying amount of an asset to
future net cash flows expected to be generated by the asset. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying amount of the assets exceed the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell. Adoption of this Statement did not
have any impact on the Company's financial position or results of operations.
 
Capitalized Interest
 
The Company capitalizes interest on expenditures made in connection with major
exploration and development projects that are not subject to current
amortization. Interest is capitalized only for the period that activities are
in progress to bring these projects to their intended use. There was no
interest capitalized in the three years ended December 31, 1996.
 
Restricted Cash--Escrow Agreements
 
The Company is contractually obligated by the terms of purchase agreements to
contribute funds to escrow accounts amounting to $1,556,000 for the future
dismantlement and abandonment of certain oil and gas properties over the
reserve life of these properties. The restricted cash is recorded as an other
asset.
 
Debt Financing Costs
 
Costs incurred in obtaining debt financing have been capitalized and are being
amortized over the term of the respective loan.
 
Derivative Financial Instruments
 
The Company applies hedge accounting for those derivative financial instruments
that are designated as a hedge. In order to qualify as a hedge, price movements
in the underlying commodity derivative must be highly correlated with the
hedged commodity. Monthly cash settlements of oil and gas price swaps are
reported as a component of revenue and cash flows from operations. The
settlements are based on the difference between the fixed swap price and the
New York Mercantile Exchange closing prices for each month during the life of
the swaps. Gains or losses attributable to the termination of a swap contract
are deferred on the balance sheet and recognized in revenue when the hedged
crude oil and natural gas is sold. There were no terminations during 1996, 1995
or 1994. When a derivative financial instrument ceases to qualify as a hedge,
or is not so designated, the change in fair value of the derivative financial
instrument is recognized in earnings currently.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
 
Income Taxes
 
Income taxes are accounted for under the asset and liability method. Deferred
tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.
 
Stock Options
 
Prior to January 1, 1996, the Company accounted for its stock option plan in
accordance with the provisions of Accounting Principles Board (APB) Opinion No.
25, Accounting for Stock Issued to Employees, and related interpretations. As
such, compensation expense would be recorded on the date of grant only if the
current market price of the underlying stock exceeded the exercise price. On
January 1, 1996, the Company adopted SFAS No. 123, Accounting for Stock-Based
Compensation, which permits entities to recognize as expense over the vesting
period the fair value of all stock-based awards on the date of grant.
Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB Opinion No. 25 and provide pro forma net income and pro forma
earnings per share disclosures for employee stock option grants made in 1995
and future years as if the fair-value-based method defined in SFAS No. 123 had
been applied. The Company has elected to continue to apply the provision of APB
Opinion No. 25 and provide the pro forma disclosure provisions of SFAS No. 123.
 
Use of Estimates
 
In preparing the Company's financial statements, management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, the 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.
 
Reclassifications
 
Certain reclassifications have been made to the financial statements to conform
to the 1996 presentation.
 
Recently Issued Accounting Pronouncements
 
In February 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 128 regarding earnings per share. SFAS No. 128 replaces the presentation of
primary earnings per share (EPS) with the presentation of basic EPS, which
excludes dilution and is computed by dividing income available to common
stockholders by the weighted-average number of shares of common stock
outstanding for the period. SFAS No. 128 also requires dual presentation of
basic EPS and diluted EPS on the face of the income statement and requires a
reconciliation of the numerators and denominators of basic EPS and diluted EPS.
The Company will adopt SFAS No. 128 for the quarter ended December 31, 1997.
 
In June 1997, FASB issued SFAS No. 130 regarding reporting comprehensive
income, which establishes standards for reporting and display of comprehensive
income and its components. The components of comprehensive income refer to
revenues, expenses, gains and losses that are excluded from net income under
current accounting standards, including foreign currency translation items,
minimum pension liability adjustments

        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
and unrealized gains and losses on certain investments in debt and equity
securities. SFAS No. 130 requires that all items recognized under accounting
standards as components of comprehensive income be reported in a financial
statement displayed in equal prominence with the other financial statements;
the total of other comprehensive income for a period is required to be
transferred to a component of equity that is separately displayed in a
statement of financial condition at the end of an accounting period. SFAS No.
130 is effective for both interim and annual periods beginning after December
15, 1997. Reclassification of financial statements for earlier periods provided
for comparative purposes is required. The Company will adopt SFAS No. 130 for
the fiscal year ending December 31, 1998.
 
In June 1997, FASB issued SFAS No. 131 regarding disclosures about segments of
an enterprise and related information. SFAS No. 131 establishes standards for
reporting information about operating segments in annual financial statements
and requires the reporting of selected information about operating segments in
interim financial reports issued to stockholders. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. SFAS No. 131 is effective for periods beginning after December 15,
1997. The Company will adopt SFAS No. 131 for the fiscal year ending December
31, 1998.
 
The Company believes that adoption of these financial accounting standards will
not have a material effect on its financial condition or results of operations.
 
Interim Financial Statements
 
The interim financial statements of the Company included herein have been
prepared by the Company without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations, although the Company believes that the
disclosures are adequate to make the information presented not misleading.
 
In the opinion of the Company, all adjustments, consisting of normal recurring
accruals, necessary to present fairly the information in the accompanying
interim financial statement have been included. The results of operations for
such interim periods are not necessarily indicative of the results for the full
year.
 
(2) INVESTMENT IN MARKETABLE SECURITIES
 
In connection with the sale of certain oil and gas properties in 1996, the
Company received $3,087,118 in marketable equity securities as proceeds from
the sale.
 
The carrying value and estimated market value of securities at December 31,
1996 are as follows:

(3) ACQUISITION OF OIL AND GAS PROPERTIES
 
During 1996, the Company acquired the interest in the Main Pass 35 field and
related pipeline assets held by Gulfland Resources, Inc. (GRI) and all of the
stock of GII for approximately $7,700,000 cash, a non-interest-bearing note for
$620,000 and 5,931 shares of the stock of the Company, then valued at $84.30
per share (the Gulfland Acquisition). The Company has also agreed to form a
limited liability company, AXEX, LLC (AXEX) that would be assigned the right to
receive revenues from a certain production handling and operating agreement,
with AXEX owned 99% by GRI and 1% by the Company, until approximately
$2,000,000 is received by GRI, at which time the ownership of AXEX reverts
entirely to the Company (The AXEX Obligation). The AXEX Obligation has been
accounted for as a contingent liability, with payments to GRI recorded as
additional costs of the Gulfland Acquisition as incurred. Pursuant to terms of
the Gulfland Acquisition agreements, the Company has the right, under certain
conditions, to reacquire the 5,931 shares of the Company's stock for the sum of
$500,000 through July 6, 1999.
 
On the same day as the Gulfland Acquisition was closed, the Company acquired,
for $1,383,000 cash, additional interests in the Main Pass 35 field from
another party. These two acquisitions (collectively, the Main Pass 35
Acquisition) resulted in the purchase of approximately 18.8 Bcfe in proved
reserves. Further, the Company also made another purchase of approximately 1.0
Bcfe for cash of $882,000.
 
During 1995, the Company acquired oil and gas properties representing 4.5 Bcfe
of proved reserves from New West Resources, Inc. (NWR). The purchase price of
approximately $7,400,000 consisted of 25,000 shares of common stock, $1,500,000
in redeemable preferred stock and an $827,000 notes payable to the seller (the
NWR Acquisition). The acquisition was accounted for as a purchase effective as
of May 1995.
 
The following summarized pro forma (unaudited) information assumes the South
Coast merger (see Note 12) and the Main Pass 35 Acquisition had occurred on
January 1, 1995 and January 1, 1996, respectively.

(a)As an inducement to Stratum, the Company provided Stratum with a 5.5%
overriding royalty interest on its existing oil and gas properties. Similarly,
the Company gave Stratum an option to purchase 15% of the common stock of the
Company at such date for $1,250,000. This option is exercisable at any time
beginning January 1, 1997 through the expiration of the option on June 30,
1999. The estimated fair value of the override and the option was recorded as
a discount to the debt and is being amortized over the life of the loan.
(b) This note was retired in 1996 with the proceeds from the revolving line of
    credit.
 
The Company was not in compliance with certain restrictive covenants of the
revolving line of credit at December 31, 1996. The Company obtained waivers to
such covenants at December 31, 1996 and through August 31, 1997. In September
1997, this indebtedness was refinanced with Credit Lyonnais, New York Branch
(Credit Lyonnais) through May 1998 and accordingly is reflected as long-term
debt at December 31, 1996.
 
Estimated aggregate maturities of long-term debt (prior to the Credit Lyonnais
refinancing) for the four years following December 31, 1996 are as follows:

redeemable at the option of the stockholder in lots of 2,500 shares annually
from December 31, 1997 through December 31, 2002. The preferred stock began
accruing dividends January 1, 1996 at an amount equal to the prime rate and was
payable upon redemption of the stock. The Company negotiated the settlement of
the redeemable preferred shares of $1,500,000 and related accrued dividends of
$67,000 and accrued interest payable of $225,000 on a note payable to the
preferred stockholder in exchange for the issuance of 7,434 common shares which

The Company recorded a valuation allowance for deferred tax assets in 1996 of
$824,653. In assessing the realizability of deferred tax assets, management
considers whether it is more likely than not that some portion or all of the
deferred tax assets will not be realized. The ultimate realization of deferred
tax assets is dependent upon

        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
the generation of future taxable income during the periods in which those
temporary differences become deductible. Management considers the scheduled
reversal of deferred tax liabilities in making this assessment. In order to
fully realize all deferred tax assets, the Company will need to generate future
taxable income of approximately $4,700,000 prior to the expiration of the net
operating loss carryforwards in 2012. The amount of the deferred tax assets
considered realizable, however, could be reduced in the near term if estimates
of future taxable income during the carryforward period are reduced.
 
(7) CONTINGENCIES
 
The Company is involved in litigation incidental to the conduct of its
business, none of which management believes is, individually or in the
aggregate, material to the Company's consolidated financial condition, results
of operations or liquidity.
 
(8) EMPLOYEE BENEFITS
 
The Company has entered into employment agreements with several key employees.
The agreements provide for bonuses payable to the employees based on several
different factors, including employee performance, revenues of the Company and
property sales. At December 31, 1996, the Company has accrued approximately
$34,000 in bonuses. There were no accrued bonuses at December 31, 1995.
 
Based on these employment agreements, the Company also assigns overriding
royalties to several key employees on certain exploration prospects. The amount
of the override reserved for employees ranges from 2% to 3% of the Company's
interest, and such amounts are deducted from revenue when earned.
 
Also pursuant to the employment agreements, three employees were granted in
1995 immediately exercisable options to purchase 10,730 shares of the
outstanding stock of the Company. These options all have three year terms and
are forfeited if the employee leaves the Company without having exercised them.
In connection with this grant the Company recognized $1,313,000 in compensation
expense in 1995, because the exercise price of the options was less than the
estimated fair value at the date of grant.
 
(9) LEASE COMMITMENTS
 
The Company has entered into various noncancelable operating lease agreements,
primarily for office rent and office equipment. As of December 31, 1996, future
minimum payments under these lease agreements are as follows:

(10) STOCK OPTIONS
 
The Company applies APB Opinion No. 25 and related interpretations in
accounting for stock-based compensation. Had compensation costs been determined
based on the fair value at the grant dates for awards consistent with the
method of SFAS No. 123, the Company's pro forma net loss and loss per share
would have been unchanged for the year ended December 31, 1996 and would have
been as follows for the year ended December 31, 1995:

(11) HEDGING ACTIVITIES AND FINANCIAL INSTRUMENTS
 
In 1996, the Company entered into commodity price swap agreements as required
by the terms of its credit facility with its Lender. These agreements provide
for the Company to receive or make payments to the Lender on the differential
between a fixed price and variable indexed price on a monthly basis. Gains and
losses related to the swap agreements are recognized as an adjustment to
revenues when the transaction occurs.
 
The Company is receiving fixed prices of from $17.82 to $18.16 per Bbl of oil,
covering a total of 1,460,000 Bbls over the life of the swaps, from May 1996
through December 2001. The Company also entered into two gas price swaps,
receiving fixed prices of $2.04 and $2.0725 per MMBtu, covering a total of
3,225,000 MMBtus over the life of the swaps, from May 1996 through December
2001. As of December 31, 1996, the swapped volumes represent approximately 76%
and 18%, respectively, of the estimated future oil and gas production of the
Company during the remaining term of the swaps. Oil and gas revenues were
decreased by $598,000 in 1996 as a result of these swaps.
 
These swaps expose the Company to counterparty credit risk to the extent the
counterparty is unable to meet its monthly settlement commitment to the
Company. The risk is ameliorated by the credit relationship and outstanding
borrowings from the lender.
 
Determination of Fair Values of Financial Instruments
 
Fair value for cash, short-term investments, receivables, payables and long-
term debt approximates carrying value. The Company was exposed to an unrealized
loss of $3,744,000 to terminate the oil and gas price swaps held at December
31, 1996. These swaps were terminated in connection with the debt refinancing
with Credit Lyonnais as discussed below.
 
(12) SUBSEQUENT EVENTS
 
In April 1997 the Company sold all of the stock of GII to D-O-R Production
Management, L.L.C. (DOR), a limited liability company in which the Company
retained a 25% nonmanaging member interest. The investment in DOR is accounted
for using the cost recovery method.
 
On August 19, 1997, an agreement was entered into by XPLOR Energy, Inc., a
Delaware corporation formed July 2, 1997 (XPLOR), AEC, South Coast Exploration
Company (South Coast), Interactive Exploration Solutions, Inc. (INEXS), SOCO
Exploration, L.P. (SOCO) and certain owners of the stock of AEC, South Coast,
INEXS and SOCO (the Acquisition Agreement), which provided for the combination
of AEC and its subsidiaries with South Coast, INEXS and SOCO, with XPLOR as the
parent company. The Acquisition Agreement was closed on September 24, 1997,
with XPLOR issuing stock to the previous owners of AEC, South Coast, INEXS, and
SOCO. In addition, three notes of $1,000,000 each were created by XPLOR payable
to the principals of INEXS and secured by the stock of INEXS (the INEXS
Shareholder Notes). The INEXS Shareholder Notes are payable on or before
September 24, 1998 and do not bear interest. The Acquisition Agreement will be
accounted for as a purchase, effective September 30, 1997, of South Coast,
INEXS and SOCO by XPLOR, as successor to AEC.
 
Also on September 24, 1997, the Company entered into a credit agreement with
Credit Lyonnais secured by all of the oil and gas properties of the Company and
the stock of all significant subsidiaries (the Credit Agreement) and

        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
repaid the balance owed under its revolving line of credit with Stratum (the
Stratum Debt). The Company was required by the terms of the Stratum Debt to
maintain certain oil and gas commodity price swaps. Those swaps were liquidated
on September 24, 1997, resulting in losses of $2,785,000.
 
The Credit Agreement provides a bridge loan through May 24, 1998, as well as a
revolving loan following and contingent upon the partial repayment of the
bridge loan. The bridge loan is for an amount of up to $35,000,000 and bears
interest at the Credit Lyonnais short-term commercial loan rate plus 2.5%,
payable quarterly, or, at the option of the Company, a fixed rate based on
short-term London Interbank Offered Rates (LIBOR) plus a margin of 4.3%,
payable at the underlying LIBOR maturities. At September 30, 1997, the LIBOR
rate, including margin, that was in effect was 10% and the outstanding amount
under the Credit Agreement was $30,750,000, leaving an amount of $4,250,000
available. Interest rates for advances under the bridge loan will increase by
1% at March 24, 1998 and by 2% at April 24, 1998. The Credit Agreement
contemplates the Company will complete an initial public offering of XPLOR's
stock (the IPO), and requires that some of the IPO proceeds will be used to
repay some or all of the bridge loan, so that the remaining outstanding
borrowings will be not greater than the amount available under the revolving
loan. The revolving loan is for a three-year period, to September 24, 2000, and
is for an amount of up to $20,000,000, subject to a semi-annually redetermined
borrowing base which is predicated on the Company's oil and gas reserves. The
first borrowing base redetermination will be as of March 31, 1998. As of
September 30, 1997 the borrowing base was $20,000,000. Advances under the
revolving loan will bear interest at the Credit Lyonnais short-term commercial
rate, payable quarterly, or, at the option of the Company, short-term LIBOR
rates plus a margin of 1.0%, payable at the underlying LIBOR maturities. Rates
under the revolving loan are subject to an increase of 0.25% if funded debt
exceeds 40% of total capitalization and, under the LIBOR option, are subject to
an increase of 0.25% if borrowings exceed 50% of the borrowing base and 0.5% if
borrowings exceed 75% of the borrowing base. The Company paid an
arrangement/structuring fee of $1,000,000 for the bridge loan and will pay a
fee of 0.643% for draws under the bridge loan. These amounts have been
capitalized at September 30, 1997, along with certain legal, engineering and
consulting expenses. The Company also pays a quarterly commitment fee of 0.5%
under the bridge loan and 0.375% under the revolving loan for amounts available
but not borrowed. The terms of the Credit Agreement, among other things,
require the Company to maintain certain minimum financial ratios and tangible
net worth of $5,500,000 plus 75% of net income, and require the Company to
pursue the IPO. The Credit Agreement also prohibits mergers, dividends and
dispositions of assets and limits additional indebtedness and investments.
 
If the IPO is not consummated prior to May 1998, the Company will be required
to refinance the bridge loan at that time or alternatively seek additional
sources of equity or debt financing. There can be no assurance the Company will
be able to successfully negotiate such equity or debt financing.
 
In connection with the Credit Agreement, the Company entered into a warrant
agreement with Credit Lyonnais that provides for the issuance to Credit
Lyonnais of a number of shares of the Company's stock equal to 5% of the number
of shares issued by the Company pursuant to the IPO (the Warrant Agreement).
The Warrant Agreement allows for the exercise, in whole or part, for two years
from the date of the effectiveness of the IPO and requires the payment of an
amount per share of 125% of the public offering price determined in the IPO.
The Warrant Agreement provides for adjustment to the number of shares subject
to the warrant in the event of stock splits and for corporate transactions with
third parties.
 
In conjunction with the Acquisition Agreement, certain former employees left
the Company and related agreements were entered into to effect the termination
of their employment contracts. Pursuant to those

agreements, 4,750 shares of the Company's stock were issued at par value to
former employees. In addition, the Company entered into an agreement to
purchase for $2,950,000 the stock of a company owned by an employee, the
principal assets of which are working interests in properties in which AEC
already owns interests. Of the $2,950,000, $750,000 was paid at closing and a
note for $2,200,000 was given by the Company for the balance (the Employee
Note). The Employee Note is unsecured, bears interest at 5.81%, payable at
maturity, and matures at the earlier of December 31, 1998 or the date of the
IPO or upon merger or sale of a significant portion of the Company's assets or
stock (Other Sale). If no IPO or Other Sale has been closed by December 31,
1998, the principal amount due on the Employee Note will be $1,350,000, which
shall be immediately payable.
 
On July 7, 1997, in anticipation of the transactions covered by the Acquisition
Agreement, the Company borrowed $5,000,000 from ERI Investments, Inc., a
company affiliated with one of the owners of South Coast and SOCO, evidenced by
a promissory note (the ERI Note). The ERI Note is unsecured, matures on July
31, 1998 and bears interest at 9% payable at maturity.
 
The ERI Note, the INEXS Shareholder Notes and Employee Note are subordinated to
the Credit Agreement.
 
(13) SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED)
 
Included herein is information with respect to oil and gas acquisition,
exploration, development and production activities, which is based on estimates
of year-end oil and gas reserve quantities and estimates of future development
costs and production schedules. The prices used in the reserve estimates are
prices the Company was receiving at each year end except where fixed and
determinable price escalations or oil and gas hedges are provided by contract.
Reserve quantities and future production at December 31, 1996 are based upon
reserve reports prepared by the independent petroleum engineering firm of
Netherland, Sewell & Associates, Inc. The reserve estimates as of December 31,
1994 and 1995 were derived from the reports of certain independent engineers.
 
These estimates are inherently imprecise and subject to substantial revision.
The Company cautions that there are many uncertainties inherent in estimating
proved reserve quantities, and in projecting future production rates and the
timing of future development expenditures, including many factors beyond the
control of the producer. Accordingly, these estimates are subject to change as
additional information becomes available. Reservoir engineering is a subjective
process of estimating underground accumulations of oil and gas that cannot be
measured in an exact way, and the accuracy of any reserve estimate is a
function of the quality of available data and of engineering and geological
interpretation and judgment. Results of drilling, testing and production
subsequent to the date of an estimate may justify revision of the estimate.
Accordingly, reserve estimates are often different from the quantities of oil
and gas that are ultimately recovered.
 
Estimates of future net cash flows from proved reserves of oil and gas were
made in accordance with SFAS No. 69, Disclosures about Oil and Gas Producing
Activities. The estimates are based on prices the Company was receiving at the
respective date. Estimated future cash inflows are reduced by estimated future
development and production costs based on year-end cost levels, assuming
continuation of existing economic conditions, and by estimated future tax
expense. Tax expense is calculated by applying the existing statutory tax
rates, including any known future changes. The results of these disclosures
should not be construed to represent the fair market value of the Company's oil
and gas properties. A market value determination would include many additional
factors including: (i) anticipated future increases and decreases in oil and
gas prices and production and development costs; (ii) an allowance for return
on investment; (iii) the value of additional reserves not considered proved at
the present, which may be recovered as a result of further exploration and
development activities; and (iv) other business risks.
 
In computing the present value of the estimated future net cash flows, a
discount factor of 10% was used pursuant to SEC regulations to reflect the
timing of those net cash flows. Present value, regardless of the discount rate
used,

is materially affected by assumptions about timing of future production, which
may prove to be inaccurate. The following reserve value data represent
estimates only, which are subject to uncertainty given the current energy
markets.

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

Standardized Measure of Discounted Future Net Cash Flows
 
The following table reflects the Standardized Measure of Discounted Future Net
Cash Flows relating to the Company's interest in proved oil and gas reserves as
of December 31, 1994, 1995 and 1996. As described in the notes to the financial
statements, pursuant to the Stratum Debt, the Company was a party to several
long-term commodity price swaps for oil and gas. As of December 31, 1996, the
swaps covered 76% and 18%, respectively, of the Company's estimated future oil
and gas production over the life of the swaps. The fixed prices to be received
under the swaps were significantly lower than the pro forma unhedged year end
prices the Company was receiving at December 31, 1996. Accordingly, the 1996
pro forma unhedged column below presents the Standardized Measure of Discounted
Future Net Cash Flows, reflecting the elimination of the price swaps (See Note
12):

The Boards of Directors and Partners
South Coast Exploration Company, SOCO
 Exploration, L.P. and Interactive
 Exploration Solutions, Inc.:
 
We have audited the accompanying combined balance sheets of South Coast
Exploration Company, SOCO Exploration, L.P. and Interactive Exploration
Solutions, Inc. (collectively, the South Coast Companies) as of December 31,
1996 and 1995, and the related combined statements of earnings,
shareholders'/partners' equity, and cash flows, for the years then ended. These
combined financial statements are the responsibility of the South Coast
Entities management. Our responsibility is to express an opinion on these
combined 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 combined financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the combined financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
combined financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of the South
Coast Companies as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

(1) GENERAL INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Organization and Business Purpose
 
South Coast Exploration Company, SOCO Exploration, L.P. and Interactive
Exploration Solutions, Inc. (collectively, the Company) are three business
entities with common ownership.
 
South Coast Exploration Company (SCEC) was formed in 1990 for exploration and
production of hydrocarbon reserves throughout the Gulf Coast areas of Texas and
Louisiana and the Permian Basin in West Texas. SCEC was wholly-owned by Ron A.
Krenzke, Philip V. Duggan and Craig S. Davis until July 1995, when Equitable
Capital Corporation (Equitable) purchased a 30% interest in SCEC for
$5,000,000.
 
Interactive Exploration Solutions, Inc. (INEXS) was also formed in 1990 by Ron
A. Krenzke, Philip V. Duggan and Craig S. Davis. INEXS provides geophysical and
geological interpretation consulting services to exploration and production
companies. INEXS is wholly-owned by the founders.
 
SOCO Exploration, L.P. (SOCO) was formed in 1995 as a limited partnership to
acquire interests in oil and gas properties. SCEC is the general partner of
SOCO with a 1% interest and Equitable owns the remaining 99% limited partner
interest.
 
In September 1997, SCEC, INEXS and SOCO became wholly owned subsidiaries of
XPLOR Energy, Inc., a Delaware corporation formed July 2, 1997 (XPLOR). See
Note 9.
 
Principles of Combination
 
The combined financial statements include the accounts of SCEC, SOCO and INEXS.
The stockholders' equity of SCEC and INEXS and partners' capital of SOCO are
presented together due to the commonality of the stockholders and partners of
SCEC, SOCO and INEXS. All material intercompany accounts and transactions have
been eliminated in the combination.
 
Cash and Cash Equivalents
 
The Company considers all highly liquid investments with an original maturity
of less than ninety days to be cash and cash equivalents.
 
Investments
 
Investments where the Company has ownership interest of less than 50% are
accounted for on the equity method; all investments with an ownership interest
of less the 20% are accounted for on the cost method.
 
Oil and Gas Properties
 
The Company follows the full cost method of accounting for oil and gas
properties. Accordingly, all costs associated with acquisition, exploration and
development of oil and gas reserves, including directly related internal costs
and geological and geophysical costs, are capitalized.

                        SOUTH COAST EXPLORATION COMPANY,
                           SOCO EXPLORATION, L.P. AND
                    INTERACTIVE EXPLORATION SOLUTIONS, INC.
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
        (THE INFORMATION AND AMOUNTS FOR INTERIM PERIODS ARE UNAUDITED)
All capitalized costs of oil and gas properties, including the estimated future
costs to develop proved reserves, are amortized on the unit-of-production
method using estimates of proved reserves. Investment in unproved properties
and major development projects are not amortized until proved reserves
associated with the projects can be determined or until impairment occurs. If
the results of an assessment indicate the properties are impaired, the amount
of the impairment is added to the capitalized cost to be amortized.
 
In addition, capitalized costs are subject to a "ceiling test," which basically
limits such costs to the aggregate of the "estimated present value" discounted
at a 10% interest rate of future net revenues from proved reserves, based on
current economic and operating conditions, plus the lower of cost or fair
market value of unproved properties.
 
Sales of proved and unproved properties are accounted for as adjustments of
capitalized costs with no gain or loss recognized, unless such adjustments
would significantly alter the relationship between capitalized costs and proved
reserves of oil and gas, in which case the gain or loss is recognized in
income. Abandonments of properties are accounted for as adjustments of
capitalized costs with no loss recognized.
 
Other Property and Equipment
 
Other property and equipment consists of furniture, office equipment and
computer hardware and software. The computer hardware and software are
depreciated on a straight-line basis over the estimated useful life of five
years and all other assets are depreciated on a double-declining basis over the
estimated useful life of the assets ranging from five to seven years. Assets
are grouped and evaluated for potential impairment based on the ability to
identify separate cash flows generated therefrom.
 
Income Taxes
 
Income taxes are accounted for under the asset and liability method. Deferred
tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.
 
SOCO is a limited partnership. As a result, SOCO's net income or loss for
federal income tax purposes is included in the tax return of the individual
partners, and may vary substantially from income or loss reported for financial
purposes. Accordingly, no recognition has been given to federal income taxes
for SOCO's operations.
 
The tax basis of the SOCO partnership net assets is approximately $2,655,000 at
December 31, 1996.
 
Revenue Recognition
 
Owners of oil and gas properties often take more or less production from a
property than entitled to based on their ownership percentages in the property.
This results in a condition known in the industry as a production imbalance.
The Company follows the sales method of accounting for production imbalances.
Under this method, the Company recognizes revenues on production as it is taken
and delivered to its purchasers. The Company's oil and gas imbalances are not
significant at December 31, 1995 and 1996.

Fair value estimates of the Company's financial instruments are made at
discrete points in time based on relevant market information. These estimates
may be subjective in nature and involve uncertainties and matters of
significant judgment and, therefore, cannot be determined with precision. The
Company believes that the carrying amounts of its current assets and
liabilities approximate the fair value of such items.
 
The carrying value of cash and cash equivalents approximates its fair value
because of the short-term maturity of these instruments.
 
Use of Estimates
 
Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities as well as reserve information which affects
the depletion calculation and the computation of the full cost ceiling
limitation to prepare these financial statements in conformity with generally
accepted accounting principles. Actual results could differ from those
estimates.
 
Earnings Per Share
 
Earnings per common share computations are not included because the information
is not meaningful.
 
Interim Financial Statements
 
The interim financial statements of the Company included herein have been
prepared by the Company without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations, although the Company believes that the
disclosures are adequate to make the information presented not misleading.
 
In the opinion of the Company, all adjustments, consisting of normal recurring
accruals, necessary to present fairly the information in the accompanying
interim financial statements have been included. The results of operations for
such interim periods are not indicative of the results for the full year.

(2) RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
In June 1997, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 130 regarding reporting
comprehensive income, which establishes standards for reporting and display of
comprehensive income and its components. The components of comprehensive income
refer to revenues, expenses, gains and losses that are excluded from net income
under current accounting standards, including foreign currency translation
items, minimum pension liability adjustments and unrealized gains and losses on
certain investments in debt and equity securities. SFAS No. 130 requires that
all items recognized under accounting standards as components of comprehensive
income be reported in a financial statement displayed in equal prominence with
the other financial statements; the total of other comprehensive income for a
period is required to be transferred to a component of equity that is
separately displayed in a statement of financial condition at the end of an
accounting period. SFAS No. 130 is effective for both interim and annual
periods beginning after December 15, 1997. Reclassification of financial
statements for earlier periods provided for comparative purposes is required.
The Company will adopt SFAS No. 130 for the fiscal year ending December 31,
1998.
 
In June 1997, FASB issued SFAS No. 131 regarding disclosures about segments of
an enterprise and related information. SFAS No. 131 establishes standards for
reporting information about operating segments in annual financial statements
and requires the reporting of selected information about operating segments in
interim financial reports issued to stockholders. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. SFAS No. 131 is effective for periods beginning after December 15,
1997. The Company will adopt SFAS No. 131 for the fiscal year ending December
31, 1998.
 
The Company believes that adoption of these financial accounting standards will
not have a material effect on its financial condition or results of operations.
 
(3) INVESTMENTS
 
Through INEXS, the Company has a 25% percent investment in INEXS One Limited
Partnership (INEXS LP1) that is accounted for using the equity method. INEXS
serves as the general partner of this partnership. INEXS LP1 rents time to
INEXS on the 3-D seismic workstations owned by the partnership. This investment
includes undistributed earnings (losses) of approximately $(6,100) and $5,900
in 1995 and 1996, respectively. Subsequent to December 31, 1996, INEXS entered
into an agreement with the partners of INEXS LP1 to purchase all of the
workstations from this partnership for approximately $165,000. Upon execution
of the purchase agreement, the partnership will be dissolved.
 
Summarized financial data for the years ended and as of December 31, 1995 and
1996 is not presented as the Company's ownership interest in INEXS LP1 is not
material to its current operations.
 
(4) CREDIT FACILITY
 
In 1995, the Company obtained a revolving credit facility from Southwest Bank
of Texas totaling $75,000. The outstanding principal balance accrues interest
at a varying rate per annum that is 1.5% above the prime lending rate. Under
the debt agreement, all amounts outstanding at any year end are due in January.
The Company had $26,000 and no amount outstanding under the facility at
December 31, 1995 and 1996, respectively.

(5) RELATED PARTY TRANSACTIONS
 
INEXS LP1, an affiliate of INEXS, charges rent for the time spent by INEXS
consultants on the 3D seismic workstations owned by the partnership. For the
years ended December 31, 1995 and 1996, INEXS LP1 charged $101,555 and
$165,156, respectively in workstation fees to INEXS. There were no amounts
payable to INEXS LP1 as of December 31, 1995. As of December 31, 1996, $44,685
is payable to INEXS LP1 for December workstation fees.
 
(6) INCOME TAXES

In assessing the reliability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. No such valuation allowance was established at
December 31, 1995 and 1996. The net deferred tax assets relate to net operating
loss carryforwards which will begin to expire in 2010 if not previously
utilized.

Rent expense under operating leases was $88,868 and $78,700 in 1995 and 1996,
respectively.
 
Contingencies
 
The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's financial position, results of operations or liquidity.
 
(8) STOCK OPTIONS
 
Weisser, Johnson & Co., a third-party financial advisor (Weisser), holds
options to acquire from certain principals of the Company 18.75% of the shares
of common stock or any other interest in SCEC which such principals obtained
after Equitable purchased a 30% interest in SCEC in July of 1995, plus 18.75%
of any options, warrants or other rights to acquire securities in SCEC which
management received at the time of the Equitable stock purchase (13,125 shares
of SCEC's common stock in total). These options have a term of seven years from
the date of closing (expiring September 8, 2002) and an exercise price of 95%
of the implicit valuation of the equity or other interest in the context of
such financing. This represents a right to purchase 13,125 shares of the common
stock of SCEC, subject to adjustment, from the principals for $2,078,125. SCEC
management holds a proxy under certain circumstances to exercise voting rights
on any securities in SCEC received by Weisser under these options until the
earlier of five years or until SCEC securities are publicly traded. The options
issued to Weisser were accounted for as a capital transaction of the Company.

(9) SUBSEQUENT EVENTS
 
On August 19, 1997, an agreement was entered into by XPLOR Energy, Inc., a
Delaware corporation formed July 2, 1997 (XPLOR), Araxas Energy Corporation
(AEC), SCEC, INEXS, SOCO and certain owners of the stock of AEC, SCEC, INEXS
and SOCO (the Acquisition Agreement), which provided for the combination of AEC
and its subsidiaries with SCEC, INEXS and SOCO, with XPLOR as the parent
company. The Acquisition Agreement was closed on September 24, 1997, with XPLOR
issuing stock to the previous owners of AEC, SCEC, INEXS and SOCO. In addition,
three notes of $1,000,000 each were created by XPLOR, payable to the principals
of INEXS and secured by the stock of INEXS (the INEXS Shareholder Notes). The
INEXS Shareholder Notes are payable on or before September 24, 1998 and do not
bear interest. The Acquisition Agreement has been accounted for as a purchase,
effective September 30, 1997, of SCEC, INEXS and SOCO by XPLOR, as successor to
AEC. In connection with the Acquisition Agreement, Weisser's option to purchase
common stock of SCEC was converted into the right to purchase common stock of
XPLOR.

(10) SUPPLEMENTAL OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED)
 
 
Reserve Quantity Information
 
Total proved and proved developed oil and gas reserves of the Company at
December 31, 1996 have been estimated by an independent petroleum engineer in
accordance with guidelines established by the Securities and Exchange
Commission (SEC). No comparable estimates were available for subsequent or
prior periods. Therefore, reserves for December 31, 1995 have been calculated
by adjusting the December 31, 1996 amounts for the respective period's
activities and consequently, no revisions of previous estimates have been
reflected. All reserve estimates are based on economic and operating conditions
existing at December 31, 1996. The future net cash flows from the production of
these proved reserve quantities were computed by applying current prices of oil
and gas, at year end (with consideration of price changes only to the extent
provided by contractual arrangements) to estimated future production of proved
oil and gas reserves less the estimated future expenditures (based on current
costs) to be incurred in developing and producing the proved reserves. All of
the Company's properties are located in the Gulf Coast areas of Texas and
Louisiana and the Permian Basin in West Texas.

(1) BASIS OF PRESENTATION
 
The accompanying statements of revenues and direct operating expenses
(Statement) were prepared from the historical accounting records of an oil and
gas consulting service and an oil and gas partnership (accrual basis,
successful efforts method of accounting for oil and gas activities, in
accordance with generally accepted accounting principles). The Statement
represents 70% of the operations of Main Pass 35, consistent with the ownership
interests of the property for the eight month period ended August 31, 1996.
 
Gross revenues and direct operating expenses included herein are not
necessarily representative of future operations. Additionally, the Statement
does not include depreciation, depletion and amortization, administrative and
general expenses, interest expense, or federal and state income taxes.
 
Complete financial statements, including a balance sheet, are not presented as
Main Pass 35 was not maintained as a separate business unit, and assets,
liabilities or indirect operating costs applicable to Main Pass 35 were not
segregated. It is not practicable to identify all assets, liabilities or
indirect operating costs applicable to Main Pass 35.
 
(2) SUPPLEMENTARY FINANCIAL INFORMATION FOR OIL AND GAS PRODUCING ACTIVITIES
 
Estimated Quantities of Proved Oil and Gas Reserves (unaudited)
 
Reserve information presented below is based on the January 1, 1997 reserve
report prepared by an independent petroleum engineer. The year ended December
31, 1995 and the eight month period ended August 31, 1996 information has been
computed by adjusting the January 1, 1997 reserve report for production and
known purchases.
 
Proved reserves are estimated quantities of crude oil, natural gas and natural
gas liquids which geological and engineering data demonstrate with reasonable
certainty to be recoverable in future years from known reservoirs under
existing economic and operating conditions. Proved developed reserves are those
which are expected to be recovered through existing wells with existing
equipment and operating methods.
 
Below are the net quantities of proved reserves and proved developed reserves
for the Main Pass 35 property:

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil
and Gas Reserves (unaudited)
 
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 (SFAS) No. 69. The
Standardized Measure does not purport to present the fair market value of the
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.

                   NOTES TO FINANCIAL STATEMENT--(CONTINUED)
Under the Standardized Measure, the year ended December 31, 1995 and the eight
month period ended August 31, 1996 future cash flows were estimated by applying
December 31, 1995 and August 31, 1996 prices, respectively, adjusted for fixed
and determinable escalations, to the estimated future production of proved
reserves. Future cash inflows for the year ended December 31, 1995 and the
eight month period ended August 31, 1996 were reduced by estimated future
production, development and dismantlement costs based on the year ended
December 31, 1995 and the eight month period ended August 31, 1996 costs,
respectively, to determine pre-tax cash inflows. Future net cash inflows were
discounted using a 10% annual discount rate to arrive at the Standardized
Measure. No deduction has been made for general and administrative expenses,
interest or provisions for depreciation, depletion or amortization, or for
taxes on income.
 
The following Standardized Measure and changes in the Standardized Measure are
based on the reserve estimate performed as of December 31, 1996, using the
appropriate year-end prices and costs.
 
Set forth below is the Standardized Measure (before income taxes) relating to
proved oil and gas reserves:

Mr. S. W. Nance
XPLOR Energy, Inc.
10200 Grogans Mill Road, Suite 500
The Woodlands, Texas 77380
 
Dear Mr. Nance:
 
In accordance with your request, we have estimated the proved reserves and
future revenue, as of September 30, 1997, to the XPLOR Energy Inc. (XPLOR)
interest in certain oil and gas properties located in Alabama, Louisiana, and
Texas as listed in the accompanying tabulations. The XPLOR interest is the
result of the combined interests of Araxas Energy Corporation and South Coast
Exploration Company. This is an update of our report which sets forth our
estimates of reserves and future revenue to the XPLOR interest as of December
31, 1996. For the purposes of this report, projections for the top 90 percent
of the properties based on present worth have been reviewed and updated. The
remainder of the projections have been "rolled forward" from our estimates as
of December 31, 1996. This report has been prepared using constant prices and
costs and conforms to the guidelines of the Securities and Exchange Commission
(SEC).
 
We estimate the net reserves and future net revenue to the XPLOR interest, as
of September 30, 1997, to be:

</TABLE>
 
The oil reserves shown include crude oil and condensate. Oil volumes are
expressed in barrels which are equivalent to 42 United States gallons. Gas
volumes are expressed in thousands of standard cubic feet (MCF) at the
contract temperature and pressure bases.
 
The estimated reserves and future revenue shown in this report are for proved
developed producing, proved developed non-producing, and proved undeveloped
reserves. In accordance with SEC guidelines, our estimates do not include any
value for probable or possible reserves which may exist for these properties.
This report does not include any value which could be attributed to interests
in undeveloped acreage beyond those tracts for which undeveloped reserves have
been estimated.
 
Future gross revenue to the XPLOR interest is prior to deducting state
production taxes and ad valorem taxes. Future net revenue is after deducting
these taxes, future capital costs, and operating expenses, but before
consideration of federal income taxes; future net revenue for the offshore
properties is also after deducting abandonment costs. In accordance with SEC
guidelines, the future net revenue has been discounted at an annual rate of 10
percent to determine its "present worth." The present worth is shown to
indicate the effect of time on the value of money and should not be construed
as being the fair market value of the properties.
 
                                      A-1

For the purposes of this report, a field inspection of the properties has not
been performed nor has the mechanical operation or condition of the wells and
their related facilities been examined. We have not investigated possible
environmental liability related to the properties; therefore, our estimates do
not include any costs which may be incurred due to such possible liability. Our
estimates of future revenue do not include any salvage value for the lease and
well equipment nor the cost of abandoning the onshore properties. Future
revenue estimates for offshore properties also do not include any salvage value
for the lease and well equipment, but do include XPLOR's estimates of the costs
to abandon the wells, platforms, and production facilities at Main Pass Block
35 Field. These abandonment costs are included in the operating expenses as a
monthly payment to an escrow account for the Main Pass Block 35 Field. No
payment to an escrow account is included for the High Island 30L Field as the
abandonment escrow account is fully funded.
 
Oil prices used in this report were provided by XPLOR and are the actual prices
received for each field as of September 30, 1997. Where actual oil prices were
not available, a September 30, 1997 South Louisiana Sweet index price of $20.35
per barrel or a West Texas Intermediate index price of $19.75 per barrel was
used, adjusted by field for regional price differentials. Gas prices used in
this report were provided by XPLOR and are the September 1997 prices received
for each field. Where actual gas prices were not available, September 1997
regional spot prices were used, adjusted for transportation fees. Oil and gas
prices for all properties are held constant in accordance with SEC guidelines.
 
Lease and well operating costs are based on operating expense records of XPLOR.
These costs include the per-well overhead expenses allowed under joint
operating agreements along with costs estimated to be incurred at and below the
district and field levels. As requested, this report includes the income XPLOR
is currently receiving for transporting oil and gas for other operators and is
shown as negative operating costs. Headquarters general and administrative
overhead expenses of XPLOR are not included. Lease and well operating costs are
held constant in accordance with SEC guidelines. Capital costs are included as
required for workovers, new development wells, and production equipment.
 
We have made no investigation of potential gas volume and value imbalances
which may have resulted from overdelivery or underdelivery to the XPLOR
interest. Therefore, our estimates of reserves and future revenue do not
include adjustments for the settlement of any such imbalances; our projections
are based on XPLOR receiving its net revenue interest share of estimated future
gross gas production.
 
The reserves included in this report are estimates only and should not be
construed as exact quantities. They may or may not be recovered; if recovered,
the revenues therefrom and the costs related thereto could be more or less than
the estimated amounts. A substantial portion of these reserves are for behind
pipe zones, undeveloped locations, and producing wells that lack sufficient
production history upon which performance-related estimates of reserves can be
based. Therefore, these reserves are based on estimates of reservoir volumes
and recovery efficiencies along with analogies to similar production. As such
reserve estimates are usually subject to greater revision than those based on
substantial production and pressure data, it may be necessary to revise these
estimates up or down in the future as additional performance data become
available. The sales rates, prices received for the reserves, and costs
incurred in recovering such reserves may vary from assumptions included in this
report due to governmental policies and uncertainties of supply and demand.
Also, estimates of reserves may increase or decrease as a result of future
operations.
 
In evaluating the information at our disposal concerning this report, we have
excluded from our consideration all matters as to which legal or accounting,
rather than engineering and geological, interpretation may be controlling. As
in all aspects of oil and gas evaluation, there are uncertainties inherent in
the interpretation of engineering and geological data; therefore, our
conclusions necessarily represent only informed professional judgments.

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

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
Delaware General Corporation Law
 
Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation),
by reason of the fact that he is or was a director, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement or
conviction or upon a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner that he reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
 
Section 145(b) of the DGCL states that a corporation may indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the corporation to
procure a judgment in its favor by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses that the Court of Chancery or such other court
shall deem proper.
 
                                      II-1
<PAGE>
 
Section 145(c) of the DGCL provides that to the extent that a director,
officer, employee or agent of a corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith.
 
Section 145(d) of the DGCL states that any indemnification under subsections
(a) and (b) of Section 145 (unless ordered by a court) shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification of the director, officer, employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth
in subsections (a) and (b). Such determination shall be made (1) by the board
of directors by a majority vote of a quorum consisting of directors who were
not parties to such action, suit or proceeding or (2) if such a quorum is not
obtainable or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion or (3) by the
stockholders.
 
Section 145(e) of the DGCL provides that expenses (including attorneys' fees)
incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it ultimately is determined that he is not
entitled to be indemnified by the corporation as authorized in Section 145.
Such expenses (including attorneys' fees) incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the board of
directors deems appropriate.
 
Section 145(f) of the DGCL states that the indemnification and advancement of
expenses provided by, or granted pursuant to, the other subsections of Section
145 shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise, both
as to action in this official capacity and as to action in another capacity
while holding such office.
 
Section 145(g) of the DGCL provides that a corporation shall have the power to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify him against such liability under the
provisions of Section 145.
 
Section 145(j) of the DGCL states that the indemnification and advancement of
expenses provided by, or granted pursuant to, Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such a person.
 
Certificate of Incorporation
 
The Certificate of Incorporation of the Company provides that a director of the
Company shall not be personally liable to the Company 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 Company
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 DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. If the DGCL is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Company, in addition to the limitation on
personal liability described above, shall be limited to the fullest extent
permitted by the amended DGCL. Further, any repeal or modification of such
provision of the Restated Certificate of Incorporation by the stockholders of
the Company shall be prospective only, and shall not adversely affect any
limitation on the personal liability of a director of the Company existing at
the time of such repeal or modification.
 
                                      II-2

Bylaws
 
The Bylaws of the Company provide that each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he or she, or a person of whom he or she is the legal
representative, is or was or has agreed to become a director or officer of the
Company or is or was serving or has agreed to serve at the request of the
Company as a director, officer, employee or agent of another corporation or of
a partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director or officer or in any other
capacity while serving or having agreed to serve as a director or officer,
shall be indemnified and held harmless by the Company to the fullest extent
authorized by the DGCL, as the same exists or may thereafter be amended (but,
in the case of any such amendment, only to the extent that such amendment
permits the Company to provide broader indemnification rights than said law
permitted the Company to provide prior to such amendment) against all expense,
liability and loss (including, without limitation, attorneys' fees, judgments,
fines, ERISA excise taxes or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to serve in the capacity which initially entitled such person to indemnity
thereunder, and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that the Company shall indemnify any such
person seeking indemnification in connection with a proceeding (or part
thereof) initiated by such person only if such proceeding (or part thereof) was
authorized by the board of directors of the Company. The Bylaws further provide
that the right to indemnification conferred thereby shall be a contract right
and shall include the right to be paid by the Company the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that, if the DGCL requires, the payment of such expenses incurred by a
current, former or proposed director or officer in his or her capacity as a
director or officer or proposed director or officer (and not in any other
capacity in which service was or is or has been agreed to be rendered by such
person while a director or officer, including, without limitation, service to
an employee benefit plan) in advance of the final disposition of a proceeding,
shall be made only upon delivery to the Company of an undertaking, by or on
behalf of such indemnified person, to repay all amounts so advanced if it shall
ultimately be determined that such indemnified person is not entitled to be
indemnified under the Bylaws or otherwise. In addition, the Bylaws provide that
the Company may, by action of its board of directors, provide indemnification
to employees and agents of the Company, individually or as a group, with the
same scope and effect as the indemnification of directors and officers provided
for in the Bylaws.
 
The Bylaws include related provisions meant to facilitate the indemnitee's
receipt of such benefits. These provisions cover, among other things: (i)
specification of the method of determining entitlement to indemnification and
the selection of independent counsel that will in some cases make such
determination; (ii) specification of certain time periods by which certain
payments or determinations must be made and actions must be taken; and (iii)
the establishment of certain presumptions in favor of an indemnitee. The
benefits of certain of these provisions are available to an indemnitee only if
there has been a change in control (as defined therein).
 
Indemnification Agreements
 
The Company has entered into Indemnification Agreements with each of its
directors. The Indemnification Agreements provide that the Company shall
indemnify the director and hold him harmless from any losses and expenses
which, in type or amount, are not insured under the directors and officers'
liability insurance maintained by the Company, and generally indemnify the
director against losses and expenses as a result of a claim or claims made
against him for any breach of duty, neglect, error, misstatement, misleading
statement, omission or other act done or wrongfully attempted by the director
or any of the foregoing alleged by any claimant or any claim against the
director solely by reason of his being a director or officer of the Company,
subject to certain exclusions. The Indemnification Agreements also provide
certain procedures regarding the right to indemnification and for the
advancement of expenses.

Underwriting Agreement
 
The Underwriting Agreement provides for the indemnification of the directors
and officers of the Company in certain circumstances.
 
Insurance
 
The Company expects to obtain a policy of liability insurance to insure its
officers and directors against losses resulting from certain acts committed by
them in their capacities as officers and directors of the Company.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
In connection with the Combination Transaction, the Company (i) acquired all of
the outstanding capital stock of Araxas, South Coast and INEXS, and all of the
outstanding limited partnership interests of SOCO, (ii) issued to the owners of
the outstanding capital stock of Araxas      shares of Common Stock and (iii)
issued to the owners of the outstanding capital stock and limited partnership
interests of the South Coast Companies      shares of Common Stock and $3.0
million principal amount of Combination Notes. The issuance of the Company's
Common Stock in the Combination Transaction was exempt from the registration
requirements of the Securities Act by virtue of Section 4(2) thereof as a
transaction not involving any public offering.
 
Prior to the consummation of this Offering, the Company will reclassify each
outstanding share of Common Stock into      shares of Common Stock (the "Stock
Split"). All share amounts set forth in the preceding paragraph have been
adjusted to reflect the Stock Split. The Stock Split is exempt from the
registration requirements of the Securities Act as it will not involve a "sale"
as defined in Section 2(3) of the Securities Act.

ITEM 17. UNDERTAKINGS.
 
The undersigned registrant hereby undertakes to provide to the Underwriters, at
the closing specified in the Underwriting Agreement, certificates representing
the shares of Common Stock offered hereby in such denominations and registered
in such names as required by the Underwriters to permit prompt delivery to each
purchaser.
 
Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the 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 of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
The undersigned registrant hereby undertakes that:
 
(1) For the purposes of determining any liability under the Securities Act, the
information omitted from the form of Prospectus filed as a 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 shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
(2) For the purpose of determining any liability under the Securities Act, 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.

the Araxas Companies.  Proceeds from the sale of Hydrocarbons produced from
Araxas Companies' Oil and Gas Interests are being received by the Araxas
Companies in a timely manner and are not being held in suspense for any reason

ACQUISITION AGREEMENT AND PLAN OF ORGANIZATION               PAGE 40 OF 56 PAGES
<PAGE>
 
     9.06 Notification of Certain Matters.  The Araxas Companies and/or
Rowsey shall give prompt notice to the South Coast Owners of, and the South
Coast Entities and/or the South Coast Owners shall give prompt notice to Araxas
of, (i) any representation or warranty contained herein and made by such party
or parties being untrue or inaccurate when made, (ii) the occurrence of any
event or development that would cause (or could reasonably be expected to cause)
any representation or warranty of such party or parties contained herein to be
untrue or inaccurate on the Closing Date, or (iii) any failure of a party or of
the parties to comply with or satisfy any covenant, condition, or agreement to
be complied with or satisfied by it or them hereunder.

and have a meeting of its shareholders, or solicit the consent of its
shareholders in lieu of such meeting, for purposes of approving this Agreement
pursuant to Section 1090.1 of the OGCA.  In connection with such meeting, Araxas
shall provide its shareholders  with such information as required by the OGCA
and such other information as the Araxas believes to be appropriate disclosure
under the circumstances.

     9.08 Financing Covenants.

          (a) New Debt and Bridge Financing.  Araxas and Newco are negotiating
     with commercial banks for a secured, revolving credit facility in the
     amount of $25 million to partially refinance the Araxas Companies'
     indebtedness owed to Stratum Group Energy Partners, L.P. ("Stratum Debt"),
     and to finance certain exploration and 3-D seismic costs, leasehold
     acquisition and development of oil and gas properties, and for general
     corporate purposes (the "New Debt").  In addition, Newco will require
     additional working capital to finance the operations of Newco and its
     Subsidiaries after the Closing Date until the closing of the Public Equity
     Transaction ("Bridge Financing").  The amount of Bridge Financing proceeds
     will be determined by Newco and Krenzke and will take into account any
     reduction or increase in the actual amount of New Debt proceeds.  The South
     Coast Principals shall cause the South Coast Entities jointly to negotiate
     with Araxas and Newco, as requested by Araxas, to obtain a loan commitment
     for the New Debt and the Bridge Financing on terms satisfactory to Newco
     and Krenzke, with  closing to occur contemporaneous with the Closing.

          (b) Newco Stock Adjustment.  If, to induce the closing of the Bridge
     Financing, Newco issues Newco equity, or securities convertible into the
     equity of Newco ("Bridge Equity"), and the Equitable Bridge Note (defined
     below) is satisfied (or assumed without recourse) in connection with the
     closing of the Bridge Financing, then, the dilution attributable to the
     Bridge Equity (determined on a fully diluted basis and without giving
     effect to this Section 9.08(b)) shall be borne as follows:  (i) first, the
     incremental dilution shall be borne by the South Coast Owners by a
     reduction in the total number of shares of Newco Common Stock to be issued
     to the South Coast Owners as set forth on Exhibit "B"


ACQUISITION AGREEMENT AND PLAN OF ORGANIZATION               PAGE 41 OF 56 PAGES
<PAGE>
 
     attached hereto, unless otherwise determined by Newco and the South Coast
     Owners, provided that such reduction in the number of shares of Newco
     Common Stock shall not exceed 9.09% of the number of such shares otherwise
     issuable to the South Coast Owners as set forth on Exhibit "B"; and (ii)
     second, to the extent that dilution resulting from issuance of the Bridge
     Equity exceeds the dilution adjustment limitation pursuant to clause (i) of
     this Section 9.08(b), such additional dilution shall be borne by the Araxas
     Owners and the South Coast Owners pari passu in accordance with each
     group's respective total ownership of Newco Common Stock, as adjusted by
     clause (i) of this Section 9.08(b).  The term "Equitable Bridge Note" means
     the promissory note of Newco and Araxas in the original principal amount of
     $5.0 million, delivered to an affiliate of Equitable effective as of 
     July 7, 1997.

     9.09 Public Equity Transaction.  Following the Closing, the parties agree
to evaluate the public offer and sale of equity securities of Newco in a firm-
commitment underwritten transaction registered under the Securities Act of 1933
and shall use commercially reasonable efforts to accomplish such transaction
prior to the end of 1997 ("Public Equity Transaction").

     9.10 Management of Newco.  Following the Closing, Rowsey shall be the
Chairman of the Board of Directors, Steven W. Nance shall be the President and
Chief Executive Officer, and Krenzke shall be Executive Vice President and Chief
Operating Officer of Newco.  Until the Board of Directors of Newco, including
the affirmative vote of each of the South Coast Members (as defined below)
determines otherwise, the South Coast Owners as a group shall be entitled to
elect a number of directors of Newco (the "South Coast Members") such that at
all times the proportion that the number of South Coast Members bears to the
full number of directors of Newco is as nearly equal as possible to the
proportion that the number of shares of Newco Common Stock owned of record by
the South Coast Owners as a group bears to the total number of outstanding
shares of Newco Common Stock (plus the shares of Newco Common Stock issuable
upon exercise of the Araxas Stock Options).  Notwithstanding the preceding
sentence, the parties agree that the covenant contained in this Section 9.10
shall apply until the agreement of Rowsey and Krenzke that such covenant no
longer shall apply, or the written opinion from the managing underwriter engaged
by Newco in connection with the Public Equity Transaction recommending that the
composition of the Newco Board be changed.

     9.11 Newco Ownership Dilution.

          (a) Clawback of Certain Araxas Owners.  If at any time after Closing
     (i) any of the shares of Newco Common Stock issued to Steven W. Nance at
     the Effective Time as a result of the Araxas Acquisition are forfeited or
     otherwise reacquired by Newco ("Nance Shares"), (ii) any of the shares of
     Newco Common Stock issued to GR, Inc. (formerly, Gulfland Resources, Inc.)
     are reacquired by Newco ("Gulfland Shares"), and/or (iii) any of the Araxas
     Stock Options expire unexercised, then the parties agree that the Araxas
     Owners


ACQUISITION AGREEMENT AND PLAN OF ORGANIZATION               PAGE 42 OF 56 PAGES
<PAGE>
 
     who are holders of Newco Common Stock at the time of such forfeiture or
     reacquisition (excluding the ownership attributable to Araxas Stock Options
     and, in the case of:  (X) reacquisition of the Nance Shares and/or Gulfland
     Shares, excluding Steven W. Nance and GR, Inc., and/or (Y) forfeiture of
     any of the Araxas Stock Options, excluding GR, Inc.) shall, as a group, be
     entitled to acquire for the aggregate par value thereof a portion of such
     reacquired or forfeited shares (or the shares underlying forfeited Araxas
     Stock Options) or other shares of Newco Common Stock from Newco, determined
     based upon a fraction, the numerator of which is equal to such
     shareholder's Total Araxas Ownership Percentage, and the denominator of
     which is equal to the group's then aggregate Total Araxas Ownership
     Percentage; provided, however, if Newco reacquires (i) the Nance Shares for
     any consideration, or (ii) the Gulfland Shares for an amount in excess of
     the fixed purchase price included in the option arrangement that currently
     encumbers such shares, the Araxas Owners shall pay Newco such consideration
     (in the case of clause (i)) or such excess consideration (in the case of
     clause (ii)) as a condition of the acquisition of such shares by the Araxas
     Owners.  The Total Araxas Ownership Percentage of an Araxas Owner may
     change from time to time as a result of the restoration of dilution
     pursuant to this paragraph (a).

          (b) Newco Option Plan.  At or prior to Closing, Newco shall adopt a
     long-term incentive plan for its employees that is mutually acceptable to
     Rowsey and the South Coast Owners ("Newco Option Plan").  The Newco Option
     Plan shall provide for grants of stock and stock-oriented awards, including
     stock options and similar arrangements with respect to Newco Common Stock.
     In addition, the parties agree initially that an amount equal to
     approximately fifteen percent (15%) of the shares of the outstanding Newco
     Common Stock after giving effect to Closing shall be authorized for awards
     under the Newco Option Plan.

          (j) Disclosure Schedule.  The matters described on the South Coast
     Disclosure Schedule (as amended) shall not, in the judgment of Araxas, be
     reasonably likely to have a Material Adverse Effect with respect to the
     South Coast Entities.

     10.03     Conditions to Obligations of All Parties.  The respective
obligations of each party are subject, at each of their options, to the
fulfillment of each of the following conditions at or prior to the Closing:

          (a) Araxas Acquisition Approval.  The Araxas Acquisition shall have
     been duly and validly approved and adopted by the Board of Directors of
     Newco and Araxas and the shareholders of Araxas, all as required by the
     OGCA and the certificate of incorporation and bylaws of Newco and Araxas.

          (b) Other Consents and Approvals.  (i) All consents, approvals,
     permits and authorizations required to be obtained prior to the Closing
     from any Governmental Authority or other person in connection with the
     consummation of the transactions contemplated hereby, and (ii) any
     preferential right to purchase an interest in any Oil and Gas Interest of
     Araxas Companies or the South Coast Entities as a result of transactions
     contemplated hereby, shall have been obtained, made or waived, except where
     such failure to obtain such consents, approvals, permits, authorizations or
     waiver would not be reasonably likely to result in a Material Adverse
     Effect on the South Coast Entities or the Araxas Companies, as the case may
     be (assuming the transactions contemplated hereby are consummated).

          (c) Related Agreements.  The relevant parties shall have negotiated,
     executed and delivered at or before the Closing (i) employment agreements
     between Newco and each of Krenzke, Davis and Duggan, and (ii) a

     of Newco Common Stock held by Equitable, on terms acceptable to Newco and
     Equitable.

          (d) Pending Actions.  None of the parties shall be subject to any
     writ, order, decree or injunction of a court of competent jurisdiction
     which prohibits or restricts the consummation of the transactions
     contemplated hereby or any pending or threatened action seeking such relief
     or seeking damages as a result thereof.

          (e) Certain Employment Agreements.  The employment agreements between
     any of the Araxas Companies and each of Messrs. Doss, Englert and
     Faulkinberry shall be terminated effective as of the Closing Date, and any

     each such Araxas Owner shall have delivered to Newco (with copies delivered
     to the other parties hereto) individual (and not joint) representations
     with respect to such person's intention, as of the Closing Date, to hold
     for such person's own account for investment the Newco Common Stock
     acquired at Closing (or issuable pursuant to Newco stock options that are
     substituted for Araxas Stock Options), and that there is no contract or
     other arrangement enforceable against such Araxas Owner, nor any plan or
     intention of such Araxas Owner, as of the Closing Date, relating to the
     sale, disposition or other transfer by such Araxas Owner of the Newco
     Common Stock issued (or issuable) to such Araxas Owner.  The employment
     agreement between South Coast and Nicola Maddox shall be terminated
     effective at Closing without any payment made or other consideration given
     or liability incurred in favor of Ms. Maddox (except as contemplated in the
     Disclosure Schedule of the South Coast Entities).

     each of Nance, GR, Inc. and Stratum Group Energy Partners, L.P. shall have
     caused each such party's Newco Common Stock or rights to acquire such stock
     to be subject to an agreement on the same proportionate terms and
     conditions as the arrangement governing such party's rights with respect to
     Araxas Common Stock (or right to acquire such stock) without any payments
     made or other consideration given to such parties, unless contemplated
     under any effective agreement with such party (which agreement shall have
     been approved by the South Coast Principals), and each such party shall
     have delivered to Newco (with copies delivered to the other parties hereto)
     individual (and not joint) representations with respect to such person's
     intention as of the Closing Date to hold for such person's own account for
     investment the Newco Common Stock acquired at Closing (or issuable pursuant
     to Newco stock options that are substituted for Araxas Stock Options), and
     that there is no contract or other arrangement enforceable against such
     Araxas Owner, nor any plan or intention of such Araxas Owner, as of the
     Closing Date, relating to the sale, disposition or other transfer by such
     Araxas Owner of the Newco Common Stock issued (or issuable) to such Araxas
     Owner.

of all matters applicable to a party at the Closing under this Agreement shall

                                 ARTICLE XIII

                              GENERAL PROVISIONS

     13.01 Nonsurvival of Representations, Warranties and Covenants.  Except
for the provisions of Sections 3.07, 9.04, 9.09, 9.10, 9.11, and 12.03, the
representations, warranties, covenants and agreements made by each of the
parties hereto shall not survive, and shall be terminated and extinguished by
the Closing.

     13.02 Entire Agreement; Amendment and Waiver.  This Agreement, together
with all Exhibits and Schedules attached hereto and all agreements and
instruments to be executed and delivered by the parties pursuant hereto,
contains the entire agreement between the parties relating to the subject matter
hereof and supersedes the Letter Agreement and any other prior agreement
arrangement and understanding between the parties regarding the subject matter
hereof. No representation, warranty, covenant, obligation, promise, inducement
or statement of intention has been made by any of the parties which is not
expressed in this Agreement.  This Agreement may be amended or changed only by
written instrument duly executed by all the parties hereto, and any alleged
amendment or change which is not so documented shall not be effective as to the
parties.  Except as expressly provided herein to the contrary, provisions of
this Agreement may be waived only by the party(ies) hereto who is entitled to
the benefit thereof by evidencing such waiver in writing, executed by such
party(ies).  Except to the extent waiver or satisfaction is deemed to exist by
the express terms of this Agreement, the failure of any party hereto to enforce
at any time any of the provisions of this Agreement shall in no way be construed
to be a waiver of any such provision, nor in any to affect the validity of this
Agreement or any party thereof or the right of any party thereafter to enforce
each and every provision.  No waiver of any breach of this Agreement shall be
held to be a waiver of any other or subsequent breach.

     13.03 Severability.  This Agreement is intended to be performed in
accordance with and only to the extent permitted by all applicable legal
requirements.  If any provision of this Agreement or the application thereof to
any person or circumstance shall for any reason and to any extent, be invalid or
unenforceable, then the performance of such offending provision shall be excused
by the parties hereto, but the remainder of this Agreement and the application
of such provision to other persons or circumstances shall not be affected
thereby, but rather shall be enforced to the greatest extent permitted by law.

without the prior written consent of each other party hereto; provided, however,
that Equitable may assign its rights and obligations hereunder to an entity all
the outstanding equity interests of which are owned directly or indirectly by
Equitable Resources, Inc. without the necessity of obtaining such consent.  No
such permitted assignment shall alter any of the obligations of an assigning
party under this Agreement or release an assigning party from obligations of
such party under this Agreement.  Upon any such assignment, the assignee shall
succeed to all rights assigned to it by, and shall become bound by all of the
obligations of, the assigning party.  Nothing in this Agreement is intended to
confer upon any person not a party hereto any rights, benefits or remedies under
or by reason of this Agreement.

                                PROMISSORY NOTE

                              Due August __, 1998
$1,000,000                                                  The Woodlands, Texas
                                                                 August __, 1997

     THIS INSTRUMENT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS. IT MAY NOT BE SOLD,
TRANSFERRED OR ASSIGNED IN THE ABSENCE OF REGISTRATION UNDER SUCH ACT AND
APPLICABLE STATE SECURITIES LAWS OR COMPLIANCE WITH AN EXEMPTION FROM SUCH
REGISTRATION. THE HOLDER, BY ACCEPTANCE HEREOF, AGREES TO PROVIDE MAKER WITH
SUCH DOCUMENTS AND ASSURANCES AS MAKER MAY REQUEST WITH RESPECT TO COMPLIANCE
WITH THE FOREGOING RESTRICTIONS PRIOR TO REGISTRATION OF ANY PURPORTED TRANSFER
OR ASSIGNMENT OF THIS INSTRUMENT.

     For value received, the undersigned, Araxas Holdings, Inc., a Delaware
corporation (the "Maker"), promises to pay _____________ ("Payee"), the
principal sum of One Million and No/100 Dollars ($1,000,000.00), without
interest, on August __, 1998, payable in lawful money of the United States of
America; provided, however, the entire principal sum evidenced by this
Promissory Note shall become immediately due and payable upon the closing of the
sale for cash of equity securities of Maker in a firm commitment underwritten
public offering by Maker registered under the Securities Act of 1933, as
amended.

     Maker may prepay all or any portion of this Promissory Note at any time and
from time to time without premium or penalty.

     If any amount of the principal payable hereunder is not paid when due, at
maturity or upon acceleration, such amount shall bear interest at the rate of
twelve percent (12%) per annum, accrued from the due date to the day on which
such default is cured to the satisfaction of the holder hereof. All such past
due sums shall be paid at the time of, and as a condition precedent to the
curing of, any default hereunder.

     Upon any distribution of assets of Maker upon the dissolution, winding up,
liquidation or reorganization of Maker, or in the event of the default of Maker
under any indebtedness for borrowed money, the payment of the principal and any
interest on this Promissory Note shall be subordinated in right of payment to
the prior payment in full of all other indebtedness of Maker.

     This Promissory Note is one of a series of promissory notes of Maker in the
aggregate principal amount of $3.0 million ("Acquisition Notes") which are
issued pursuant to that certain Acquisition Agreement and Plan of Organization
("Agreement") dated August __, 1997, and shall be subject to the terms of the
Agreement.

     To secure payment and performance of this Promissory Note and the other
Acquisition Notes, Maker hereby grants to and in favor of R. A. Krenzke, as
agent ("Agent") for and on behalf of the holders of the Acquisition Notes, a
security interest covering all of Maker's right, title and interest in the INEXS
Shares (as defined in the Agreement), and any and all products or proceeds
thereof ("Collateral"). The security interest granted by the preceding sentence
shall be subordinate to the rights of any New Debt and/or Bridge Financing
lender(s) (as such terms are defined in the Agreement), who shall be granted a
security interest in the Collateral that will be first and superior in all
respect to the rights of the holders.

     To induce holder to accept this Note, Newco hereby agrees as follows: (i)
unless the advance approval of Agent is obtained approving a proposed deviation,
INEXS (as defined in the Agreement) shall be operated in the ordinary course and
substantially as INEXS' business activities are conducted as of the date hereof;
(ii) without the advance approval of Agent, Newco shall not sell, assign,
exchange, or transfer the Collateral, or all or substantially all of the assets
of INEXS, except as security for the New Debt or Bridge Financing indebtedness;
and (iii) no bankruptcy, dissolution, liquidation or other similar proceeding
shall be filed by, against or on behalf of Maker that is not dismissed within
thirty (30) days.

     Maker and all endorsers, sureties, guarantors, and all other persons who
may become liable for all or any part of this obligation severally waive
presentment for payment, protest and notice of non-payment. Said parties consent
to any extension of time (whether one or more) of payment hereof, and renewal
(whether one or more) hereof, and any release of any party liable for payment of
this obligation. Any such extension, renewal or release may be made without
notice to any such party and without discharging such party's liability
hereunder. Maker and the Payee stipulate and agree that none of the terms and
provisions hereof shall ever be construed as a contract to pay for the use,
forbearance or detention of money, providing for interest at a rate in excess of
the maximum interest rate permitted to be charged by applicable law.

     Notwithstanding anything to the contrary contained in this Promissory Note,
the holder hereof shall not be entitled to obtain a deficiency judgment against
the Maker for the payment of principal and any interest on this Promissory Note.

     THIS PROMISSORY NOTE AND THE INDEBTEDNESS EVIDENCED HEREBY SHALL BE
INTERPRETED ACCORDING TO THE INTERNAL LAWS OF THE STATE OF TEXAS.

     IN WITNESS WHEREOF, the undersigned has caused this Promissory Note to be
executed and delivered on its behalf by its duly authorized representative on
this ____ day of ____________ 1997.

New York Banking Law of a foreign banking corporation organized under the laws

     Borrower has requested that Lenders extend credit to Borrower not to exceed
a total outstanding principal amount of $35,000,000 to be used by Borrower as
provided in SECTION 7.1(A) consisting of a multiple advance term loan to be
funded by Lenders from time to time, a portion of which may, upon the
satisfaction of certain conditions as provided herein, be converted into a
revolving-credit facility of $20,000,000 (the "REVOLVING FACILITY") to be funded
by Lenders from time to time in a combination of advances and letters of credit
(as that amount may be reduced by certain Borrowing Base restrictions) to be
used by the Borrower as provided in SECTION 7.1(B).  Lenders are willing to
extend the requested credit on the terms and conditions of this agreement.

     ACCORDINGLY, for adequate and sufficient consideration, Borrower, Lenders,

     ================================================================================
</TABLE>


          (b)  For all Revolving Facility Borrowings, if any, the Applicable
     Margin shall be calculated as follows:

               (i)    The Applicable Margin is subject to adjustment (upwards or
          downwards, as appropriate) based on the ratio of the Companies' Funded
          Debt to Capitalization and the ratio of the outstanding Principal Debt
          under the Revolving Facility to the Borrowing Base, as stated in the
          table below.

               (ii)   From the Facility Conversion Date through the date that
          Agent receives the Current Financials and Compliance Certificate for
          the quarter ending December 31, 1997, the Applicable Margin shall be
          calculated assuming that the ratio of the Companies' Funded Debt to
          Capitalization is less than 40% and the ratio of the outstanding
          Principal Debt under the Revolving Facility to the Borrowing Base is
          less than 50%.

               (iii)  After receipt of the Current Financials and Compliance
          Certificate for the quarter ending December 31, 1997, the Applicable
          Margin in effect at any time (whether in the middle of an Interest
          Period or otherwise) is based upon the ratio of the Companies' Funded
          Debt to Capitalization as determined from the Current Financials and
          related Compliance Certificate then most recently received by Agent,
          effective as of the date received by Agent.

               (iv)   For purposes of the definition of APPLICABLE MARGIN, (i)
          Capitalization and Funded Debt are each determined as of the last day
          of the most recently completed fiscal-quarter and (ii) the ratio of
          the outstanding Principal Debt under the Revolving Facility to the
          Borrowing Base is determined as of the last day of the most recently
          completed fiscal quarter by dividing the average outstanding Principal
          Debt under the Revolving Facility for each day during such quarter by
          the Borrowing Base in effect as of the last day of such quarter.

               (v)    If Borrower fails to timely furnish to Agent any
          Financials and related Compliance Certificate as required by this
          agreement, then the maximum Applicable Margin shall apply from the
          date those Financials and related Compliance Certificate

- ----------  ----------                                                        
Lender severally but not jointly agrees to extend credit to Borrower in
accordance with the following provisions.

     2.1    (a)    Bridge Facility. Each Lender severally but not jointly agrees
                   --------------- 
to lend to Borrower that Lender's Commitment Percentage of requested Borrowings
under the Bridge Facility which Borrower may borrow and repay under this
agreement subject to the following conditions:

            (i)    Each Borrowing may only occur on a Business Day on or after
     the Closing Date and before the Bridge Termination Date;

            (ii)   Each Borrowing may only be $500,000 or a greater integral
     multiple of $100,000 if a Base-Rate Borrowing or $1,000,000 or a greater
     integral multiple of $500,000 if a LIBOR-Rate Borrowing;

            (iii)  The sum of the Principal Debt outstanding under the Bridge
     Facility plus the LC Exposure may never exceed the total Bridge
     Commitments; and

            (iv)   The Commitment Usage (whether direct or participated) may
     never exceed that Lender's Bridge Commitment.

No Borrowing under the Bridge Facility which has been repaid may be reborrowed.

     (b)    Revolving Facility.  Provided that each of the Facility Conversion
            ------------------                                                
Conditions shall have been fully satisfied, each Lender severally but not
jointly agrees to lend to Borrower that Lender's

                                       14
<PAGE>
 
Commitment Percentage of requested Borrowings under the Revolving Facility which
Borrower may borrow, repay, and reborrow under this agreement subject to the
following conditions:

          (i)     Each Borrowing may only occur on a Business Day on or after
     the Facility Conversion Date and before the Revolving Termination Date;

          (ii)    Each Borrowing may only be $500,000 or a greater integral
     multiple of $100,000 if a Base-Rate Borrowing or $1,000,000 or a greater

          (iii)   The sum of the Principal Debt outstanding under the Revolving
     Facility plus the LC Exposure may never exceed at any time, the lesser of
     EITHER the total Revolving Commitments OR the Borrowing Base;

          (iv)    The Commitment Usage (whether direct or participated) may
     never exceed that Lender's Revolving Commitment; and

          (v)     All remaining Borrowings outstanding under the Bridge Facility
     on the Facility Conversion Date (after giving effect to all prepayments of
     Principal Debt made on such date) shall be and be deemed to be Borrowings
     under the Revolving Facility.

      2.2 Borrowing Procedure.  The following procedures apply to Borrowings:
          -------------------                                                

          (a)     Borrowing Request. Borrower may request a Borrowing by making
                  -----------------
     or delivering a Borrowing Request (that may be telephonic if confirmed
     immediately in writing by 2:00 p.m. on the same Business Day) to Agent,
     which is irrevocable and binding on Borrower, stating the Type, amount, and
     Interest Period for each Borrowing and which must be received by Agent no
     later than 11:00 a.m. on the (i) third Business Day before the date on
     which funds are requested (the "BORROWING DATE") for any LIBOR-Rate
     Borrowing, or (ii) Borrowing Date for any Base-Rate Borrowing. Agent shall
     promptly notify each Lender of any Borrowing Request.

          (b)     Funding.  Each Lender shall remit its Commitment Percentage of
                  -------                                                       
     each requested Borrowing to Agent's principal office in New York, New York,
     in funds that are available for immediate use by Agent by 1:00 p.m. on the
     applicable Borrowing Date.  Subject to receipt of those funds, Agent shall
     (unless to its actual knowledge any of the applicable conditions precedent
     have not been satisfied by Borrower or waived by the requisite Lenders
     under SECTION 14.8) make those funds available to Borrower by (at
     Borrower's option) (i) wiring the funds to or for the account of Borrower
     at the direction of Borrower or (ii) depositing the funds in Borrower's
     account with Agent.

          (c)     Funding Assumed. Absent contrary written notice from a Lender,
                  ---------------  
     Agent may assume that each Lender has made its Commitment Percentage of the
     requested Borrowing available to Agent on the applicable Borrowing Date,
     and Agent may, in reliance upon such assumption (but shall not be required
     to), make available to Borrower a corresponding amount. If a Lender fails
     to make its Commitment Percentage of any requested Borrowing available to
     Agent on the applicable Borrowing Date, Agent may recover the applicable
     amount on demand, (i) from that Lender together with interest, commencing
     on the Borrowing Date and ending on (but excluding) the date Agent recovers
     the amount from that Lender, at an annual interest rate equal to the
     Federal-Funds Rate, or (ii) if that Lender fails to pay its amount upon
     demand, then from Borrower.  No Lender is responsible for the failure of
     any other Lender to make its Commitment Percentage of any Borrowing
     available as required by

                                       15
<PAGE>
 
     SECTION 2.2(B); however, failure of any Lender to make its Commitment
     Percentage of any Borrowing so available does not excuse any other Lender
     from making its Commitment Percentage of any Borrowing so available.

      2.3 Letters of Credit.
          ----------------- 

          (a) Conditions.  Subject to the terms and conditions of this agreement
              ----------                                                        
     each Lender, if requested, agrees to issue LCs from and after (i) the
     Closing Date to and excluding the Bridge Termination Date under the Bridge
     Facility upon Borrower's making or delivering an LC Request and delivering
     an LC Agreement, both of which must be received by Agent and the Issuing
     Lender no later than the third Business Day before the Business Day on
     which the requested LC is to be issued, so long as (x) no such LC may
     expire after the Bridge Stated-Termination Date, (y) the LC Exposure (after
     giving effect to such requested LC) would not exceed twenty percent (20%)
     of the Borrowing Base and (z) the limitations in SECTION 2.1(A)(III) are
     not exceeded, and (ii) the Facility Conversion Date upon Borrower's making
     or delivering an LC Request and delivering an LC Agreement, both of which
     must be received by Agent and the Issuing Lender no later than the third
     Business Day before the Business Day on which the requested LC is to be
     issued, so long as (x) no such LC may expire after the earlier to occur of
     the first anniversary of its issuance date or three Business Days before
     the Revolving Stated-Termination Date, (y) the LC Exposure (after giving
     effect to such requested LC) would not exceed twenty percent (20%) of the
     Borrowing Base and (z) the limitations in SECTION 2.1(B)(III) are not
     exceeded.

          (b) Participation.  Immediately upon an Issuing Lender's issuance of
              -------------                                                   
     any LC, that Issuing Lender shall be deemed to have sold and transferred to
     each other Lender, and each other Lender shall be deemed irrevocably and
     unconditionally to have purchased and received from that Issuing Lender,
     without recourse or warranty, an undivided interest and participation to
     the extent of such Lender's Commitment Percentage in the LC and all
     applicable Rights of that Issuing Lender in the LC -- other than Rights to
     receive certain fees provided in SECTION 4.3 to be for that Issuing
     Lender's sole account.

          (c) Reimbursement Obligation.  To induce each Issuing Lender to issue
              ------------------------                                         
     and maintain LCs, and to induce Lenders to participate in issued LCs,
     Borrower agrees to pay or reimburse each Issuing Lender (i) on the first
     Business Day after an Issuing Lender notifies Agent and Borrower that it
     has made payment under an LC, the amount paid by that Issuing Lender and
     (ii) within five Business Days after demand, the amount of any additional
     fees Agent customarily charges for amending LCs Agreements, for honoring
     drafts, and for taking similar action in connection with letters of credit.
     If Borrower has not reimbursed that Issuing Lender for any drafts paid by
     the date on which reimbursement is required under this section, then Agent
     is irrevocably authorized to fund Borrower's reimbursement obligations as a
     Base-Rate Borrowing under the Bridge Facility or the Revolving Facility, as
     applicable, if proceeds are available under the Revolving Facility and if
     the conditions in this agreement for such a Borrowing (other than any
     notice requirements or minimum funding amounts) have, to Agent's knowledge,
     been satisfied.  The proceeds of that Borrowing shall be advanced directly
     to that Issuing Lender to pay Borrower's unpaid reimbursement obligations.
     If funds cannot be advanced under the Bridge Facility or the Revolving
     Facility, as applicable, then Borrower's reimbursement obligation shall
     constitute a demand obligation.  Borrower's obligations under this section
     are absolute and unconditional under any and all circumstances and
     irrespective of any setoff, counterclaim, or defense to payment that
     Borrower may have at any time against any Issuing Lender or any other
     Person.  From the date that an Issuing Lender pays a draft under a LC until
     Borrower either reimburses or is obligated to reimburse that Issuing Lender
     for that draft under this section, the amount of that draft bears interest
     payable to that

                                       16
<PAGE>
 
     Issuing Lender at the rate then applicable to Base-Rate Borrowings.  From
     the due date of the respective amounts due under this section, to the date
     paid (including any payment from proceeds of a Base-Rate Borrowing), unpaid
     reimbursement amounts accrue interest that is payable on demand at the
     Default Rate.

          (d) General.  The applicable Issuing Lender shall promptly notify
              -------                                                      
     Agent and Borrower of the date and amount of any draft presented for honor
     under any LC (but failure to give notice will not affect Borrower's
     obligations under this agreement).  That Issuing Lender shall pay the
     requested amount upon presentment of a draft unless presentment on its face
     does not comply with the terms of the applicable LC.  When making payment,
     that Issuing Lender may disregard (i) any default or potential default that
     exists under any other agreement (other than the applicable LC) and (ii)
     obligations under any other agreement (other than the applicable LC) that
     have or have not been performed by the beneficiary or any other Person (and
     that Issuing Lender is not liable for any of those obligations).
     Borrower's reimbursement obligations to that Issuing Lender and Lenders,
     and each Lender's obligations to that Issuing Lender, under this section
     are absolute and unconditional irrespective of, and that Issuing Lender is
     not responsible for, (i) the validity, enforceability, sufficiency,
     accuracy, or genuineness of documents or endorsements (even if they are in
     any respect invalid, unenforceable, insufficient, inaccurate, fraudulent,
     or forged), (ii) any dispute by any Company with or any Company's claims,
     setoffs, defenses, counterclaims, or other Rights against that Issuing
     Lender, any Lender, or any other Person, or (iii) the occurrence of any
     Potential Default or Default.  However, nothing in this agreement
     constitutes a waiver of Borrower's Rights to assert any claim or defense
     based upon the gross negligence or willful misconduct of any Lender.  The
     Issuing Lender shall promptly pay to Agent for Agent to promptly distribute
     reimbursement payments received from Borrower to all Lenders according to
     their Pro Rata Part of the Revolving Facility.

          (e) Obligation of Lenders.  If Borrower fails to reimburse an Issuing
              ---------------------                                            
     Lender as provided in SECTION 2.3(C) by the date on which reimbursement is
     due under that section, and funds cannot be advanced under the Bridge
     Facility or the Revolving Facility, as applicable, to satisfy the
     reimbursement obligations, then Agent shall promptly notify each Lender of
     Borrower's failure, of the date and amount paid, and of each Lender's
     Commitment Percentage of the unreimbursed amount.  Each Lender shall
     promptly and unconditionally make available to Agent in immediately
     available funds its Commitment Percentage of the unpaid reimbursement
     obligation, subject to the limitations of SECTION 2.1(A) (IV) or (B)(IV),
     as the case may be.  Funds are due and payable to Agent before the close of
     business on the Business Day when Agent gives notice to each Lender of
     Borrower's reimbursement failure (if notice is given before 1:00 p.m.) or
     on the next succeeding Business Day (if notice is given after 1:00 p.m.).
     All amounts payable by any Lender accrue interest after the due date at the
     Federal-Funds Rate from the day the applicable draft or draw is paid by
     Agent to (but not including) the date the amount is paid by the Lender to
     Agent.  Upon receipt of those funds, Agent shall make them available to the
     Issuing Lender.

          (f) Duties of Issuing Lender.  Each Issuing Lender agrees with each
              ------------------------                                       
     Lender that it will exercise and give the same care and attention to each
     LC as it gives to its other letters of credit.  Each Lender and Borrower
     agree that, in paying any draft under any LC, no Issuing Lender has any
     responsibility to obtain any document (other than any documents expressly
     required by the respective LC) or to ascertain or inquire as to any
     document's validity, enforceability, sufficiency, accuracy, or genuineness
     or the authority of any Person delivering it.  Neither any Issuing Lender
     nor its Representatives will be liable to any Lender or any Company for any
     LC's use or for any beneficiary's acts or omissions.  Any action, inaction,
     error, delay, or omission taken or suffered by any Issuing Lender or any of
     its Representatives

                                       17
<PAGE>
 
     in connection with any LC, applicable drafts or documents, or the
     transmission, dispatch, or delivery of any related message or advice, if in
     good faith and in conformity with applicable Laws and in accordance with
     the standards of care specified in the Uniform Customs and Practices for
     Documentary Credits (1993 Revision), International Chamber of Commerce
     Publication No. 500 (as amended or modified), is binding upon the Companies
     and Lenders and, except as provided in Section 2.4(e), does not place that
     Issuing Lender or any of its Representatives under any resulting liability
     to any Company or any Lender.  Agent is not liable to any Company or any
     Lender for any action taken or omitted, in the absence of gross negligence
     or willful misconduct, by that Issuing Lender or its Representative in
     connection with any LC.

          (g) Cash Collateral.  On the Bridge Termination Date or the Revolving
              ---------------                                                  
     Termination Date, as applicable, and if requested by Determining Lenders
     while a Default pursuant to SECTION 11.1 exists, Borrower shall provide
     Agent, for the benefit of Lenders, cash collateral in an amount equal to
     the then-existing LC Exposure, which cash collateral shall be invested by
     Agent solely in Permitted Investments of the type described in items 1-3 of
     SCHEDULE 9.8 as Agent, in its sole discretion, may determine.  All income
     and proceeds from the investment of such cash collateral shall be and be
     deemed to constitute additional cash collateral for the Obligation.
     Borrower hereby acknowledges and agrees that any loss of the principal of,
     and/or accrued interest on, any such cash collateral invested by Agent as
     provided herein shall be for the account of Borrower and shall not reduce
     or diminish in any manner whatsoever the Obligation or Borrower's
     obligation to provide cash collateral as provided herein.

          (h) INDEMNIFICATION.  BORROWER SHALL PROTECT, INDEMNIFY, PAY, AND SAVE
              ---------------                                                   
     AGENT, EACH LENDER, AND THEIR RESPECTIVE REPRESENTATIVES HARMLESS FROM AND
     AGAINST ANY AND ALL CLAIMS, DEMANDS, LIABILITIES, DAMAGES, LOSSES, COSTS,
     CHARGES, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) WHICH ANY OF
     THEM MAY INCUR OR BE SUBJECT TO AS A CONSEQUENCE OF THE ISSUANCE OF ANY LC,
     ANY DISPUTE ABOUT IT, OR THE FAILURE OF   ANY ISSUING LENDER TO HONOR A
     DRAW REQUEST UNDER ANY LC AS A RESULT OF ANY ACT OR OMISSION (WHETHER RIGHT
     OR WRONG) OF ANY PRESENT OR FUTURE TRIBUNAL.  HOWEVER, NO PERSON IS
     ENTITLED TO INDEMNITY UNDER THE FOREGOING FOR ITS OWN GROSS NEGLIGENCE OR
     WILLFUL MISCONDUCT.

          (i) LC Agreements.  Although referenced in any LC, terms of any
              -------------                                              
     particular agreement or other obligation to the beneficiary are not
     incorporated into this agreement in any manner.  The fees and other amounts
     payable with respect to each LC are as provided in this agreement, drafts
     under each LC are part of the Obligation, only the events specified in this
     agreement as a Default shall constitute a default under any LC, and the
     terms of this agreement control any conflict between the terms of this
     agreement and any LC Agreement.

     2.4 Borrowing Notices and LC Requests.  Each Borrowing Request (whether
         ---------------------------------                                  
telephonic or written) and LC Request constitutes a representation and warranty
by Borrower that as of the Borrowing Date or the date of issuance of the
requested LC, as the case may be, that all of the conditions precedent in
SECTION 6 have been satisfied.

     2.5 Termination. Borrower may -- upon giving at least five Business Days
         -----------                                                        
prior written and irrevocable notice to Agent -- terminate all or part of the
Bridge Facility or the Revolving Facility. Each partial termination must be in
an amount of not less than $1,000,000 or a greater integral multiple of
$1,000,000 and must be ratable in accordance with each Lender's Commitment
Percentage. At the time of any termination, Borrower shall pay to Agent, for the
account of each Lender, as applicable, the amount of (i) with respect to any
such termination of the Bridge Facility, the excess,

                                       18
<PAGE>
 
if any, of the sum of the outstanding Principal Debt plus the LC Exposure over
the total Bridge Commitments after giving effect to such termination, and (ii)
with respect to any such termination of the Revolving Facility, any Borrowing
Base Deficiency then existing or which would result after giving effect to such
termination, in each case together with all accrued and unpaid fees under this
agreement and the interest attributable to the amount of that reduction, and any
related Funding Loss.  Any part of the Bridge Commitments or the Revolving
Commitments that are terminated may not be reinstated.

     2.6  Borrowing Base Determinations.
          ----------------------------- 

          (a) As of the Closing Date, the Borrowing Base is acknowledged by the
Borrower, the Agent and the Lenders to be $20,000,000.

          (b) The Borrowing Base shall be redetermined by the Lenders semi-
annually through the Revolving Termination Date, within ninety (90) days after
each December 31 and within sixty (60) days after each June 30, with the first
such Borrowing Base redetermination under this Agreement to be made on or before
March 31, 1998 for the Mortgaged Properties as of December 31, 1997, in
accordance with the standard engineering and lending policies and practices
customary for loans of this nature and on the basis of information supplied by
the Borrower in compliance with the provisions of this Agreement, including,
without limitation, the Reserve Reports, and all other information available to
the Lenders.  Notwithstanding the foregoing, the Lenders may at their discretion
make redeterminations of the Borrowing Base at any time and from time to time
after (but not before) the first semi-annual redetermination made hereunder,
including, without limitation, upon the occurrence of any sale, transfer,
release or other disposition or loss or relinquishment of any Collateral by the
Borrower, provided, that nothing in this provision shall be deemed to authorize
any sale of any property prohibited pursuant to this agreement or any other Loan
Document; and provided, further, that Lenders may only make one such
redetermination during each six month period between the required, semi-annual
redeterminations described in the first sentence of this Section 2.6(b).  In
addition to the determinations of the Borrowing Base required pursuant to this
SECTION 2.6(B) hereof, special determinations thereof may at any time be
requested by Borrower if it, in good faith, (i) believes that events have
occurred or conditions exist that could increase the then current Borrowing Base
by at least ten percent (10%) or (ii) desires to mortgage, or cause to be
mortgaged, additional Mineral Interests to increase the Borrowing Base by at
least ten percent (10%), and Borrower has tendered to the Agent, to be
distributed by Agent to each Lender, an engineering fee in the amount of
$5,000.00 for each Lender.  Upon any such special determination of the Borrowing
Base and, if requested by Agent, Borrower shall submit both (i) a current report
of a firm of independent petroleum engineers acceptable to Agent, prepared in
accordance with customary standards and procedures of the petroleum industry
which report shall (A) evaluate the additional Mineral Interests subject to such
redetermination not previously evaluated in the most recent Reserve Report
delivered to Agent (in the same manner as provided in this SECTION 2.6(B) for
other such redeterminations) and (B) be dated within sixty (60) days of such
requested redetermination, and, (ii) title opinions, environmental reports and
other information reasonably requested by and in form and substance acceptable
to Agent, for those additional Mineral Interests which Borrower desires to be
considered within the Borrowing Base.  Adjustments to the Borrowing Base based
upon the addition of Mineral Interests shall not be effective prior to the date
of filing and recording of such Collateral Documents as required by Agent.

          (c) Upon each borrowing base redetermination, the Agent shall notify
the Borrower verbally (confirming such notice promptly in writing) of such
determination, and the Borrowing Base so communicated to the Borrower shall
become effective upon such verbal notification and shall remain in effect until
the next subsequent borrowing base redetermination in accordance with the terms
hereof.

                                       19
<PAGE>
 
          (d) The Borrowing Base shall represent the determination by all of the
Lenders, in their sole discretion and in accordance with their standard
engineering and lending policies and practices customary for loans of this
nature, of the value, for loan purposes, of the Collateral. Furthermore, the
Borrower acknowledges that the determination of the Borrowing Base contains an
equity cushion (market value in excess of loan value), which is acknowledged by
the Borrower to be essential for the adequate protection of the Lenders.  In any
event, the Borrowing Base shall at no time exceed 60% of the Agent's base case
net present value determination.

     2.7  Extension of Termination Date.  Provided that the Facility Conversion
          -----------------------------                                        
Date shall have occurred and the Revolving Termination Date shall not have
occurred, Borrower may request the Lenders, by written notice to the Agent, at
least 90 but not more than 180 days prior to the then effective Revolving
Stated-Termination Date, to consent to a one-year extension of the Revolving
Stated-Termination Date to August 31, 2001.  Each Lender shall, in its sole
discretion, determine whether to consent to such request and shall notify the
Agent of its determination within 30 days of such Lender's receipt of notice of
such request.  If such request shall have been consented to by all the Lenders,
the Agent shall notify Borrower in writing of such consent, and such extension
shall become effective upon the delivery by Borrower to the Agent and each
Lender, on or prior to the then effective Revolving Stated-Termination Date of
(i) a certificate of a Responsible Officer of Borrower, dated such date, as to
the accuracy, both before and after giving effect to such proposed extension, of
the representations and warranties set forth in Section 7 and as to the absence,
both before and after giving effect to such proposed extension, of any Default
or Potential Default and (ii) such other information, instruments, reports and
documents as Agent may reasonably request.

 SECTION 3.  TERMS OF PAYMENT.
 ---------   ---------------- 

     3.1     Notes and Payments.
             ------------------ 

             (a)   Notes. Principal Debt under the Bridge Facility and, if
                   -----                                                  
     applicable, the Revolving Facility is evidenced by the Notes, one payable
     to each Lender in amount equal to its Pro Rata Part of $100,000,000.
     Borrower understands, acknowledges and agrees that the execution and
     delivery by Borrower of each Lender's Note in such original principal
     amount does not imply, and shall not be construed to create, any obligation
     or commitment on the part of any Lender to make any advances or issue or
     participate in any LC's in excess of, in the aggregate, such Lender's
     Commitment; the higher amount represented by such Lender's Note being for
     ease of administration only in the event that the Lenders and the Borrower
     may hereafter agree, in writing, to increase the Commitments upon the
     request of Borrower and in accordance with such terms and conditions as the
     Lenders may then require after receipt of new and independent credit
     approvals by each Lender, based upon such financial and engineering
     information, industry trends and other economic conditions as each Lender,
     in the exercise of its sole discretion, may deem appropriate at the time to
     evaluate such request.

             (b)   Payment. Borrower must make each payment and prepayment on
                   ------- 
     the Obligation to Agent's principal office in New York, New York in
     immediately available funds by 1:00 p.m. on the day due; otherwise, but
     subject to SECTION 3.8, those funds continue to accrue interest as if they
     were received on the next Business Day. Agent shall promptly pay to each
     Lender the part of any payment or prepayment to which that Lender is
     entitled under this agreement on the same day Agent receives the funds from
     Borrower.

             (c)   Payment Assumed. Unless Agent has received notice from
                   ---------------
     Borrower prior to the date on which any payment is due under this agreement
     that Borrower will not make that payment in full, Agent may assume that
     Borrower has made the full payment due and Agent may, in reliance upon that
     assumption, cause to be distributed to each Lender on that date the

                                       20
<PAGE>
 
     amount then due to each Lender.  If and to the extent Borrower does not
     make the full payment due to Agent, each Lender shall repay to Agent on
     demand the amount distributed to that Lender by Agent together with
     interest for each day from the date that Lender received payment from Agent
     until the date that Lender repays Agent (unless such repayment is made on
     the same day as such distribution), at an interest rate equal to the
     Federal-Funds Rate.

     3.2  Interest and Principal Payments.
          ------------------------------- 

          (a) Interest.  Accrued interest on each LIBOR-Rate Borrowing is due
              --------                                                       
     and payable on the last day of its respective Interest Period.  If any
     Interest Period for a LIBOR-Rate Borrowing is greater than three months,
     then accrued interest is also due and payable on the date three months
     after the commencement of the Interest Period.  Accrued interest on each
     Base-Rate Borrowing is due and payable on the last day of each March, June,
     September, and December -- commencing on the first of those dates that
     follows the Closing Date -- and, with respect to Borrowings under the (i)
     Bridge Facility, on the Bridge Termination Date and (ii) Revolving
     Facility, on the Revolving Termination Date.

          (b) Principal.  The entire outstanding Principal Debt under the Bridge
              ---------                                                         
     Facility is due and payable on the Bridge Termination Date.  The entire
     outstanding Principal Debt under the Revolving Facility, if any, is due and
     payable on the Revolving Facility Termination Date.  Before such dates,
     Borrower may at any time prepay, without penalty and in whole or in part,
     the Principal Debt so long as (i) each voluntary partial prepayment must be
     in a principal amount not less than $500,000 or a greater integral multiple
     of $100,000 and (ii) Borrower shall pay any related Funding Loss upon
     demand.  Conversions under SECTION 3.10 are not prepayments.

          (c) Mandatory Prepayments.  If at any time prior to the Facility
              ---------------------                                       
     Conversion Date, the outstanding Principal Debt under the Bridge Facility
     exceeds the total Bridge Facility Commitments, Borrower shall immediately
     make prepayments to Agent (with any related Funding Loss) of the
     outstanding Principal Debt in an amount equal to such excess.  At any time
     a Borrowing-Base Deficiency under the Revolving Facility exists, Borrower
     shall make prepayments to Agent (with any related Funding Loss) of the
     outstanding Principal Debt under the Revolving Facility so that (i) such
     Borrowing-Base Deficiency has been reduced by at least 50% within 90 days
     after notice from Agent of the existence of such Borrowing-Base Deficiency,
     and (ii) such Borrowing-Base Deficiency no longer exists on or before the
     day which is 180 days after notice from the Agent of the existence of such
     Borrowing-Base Deficiency.

     3.3  Interest Options.  Except that the LIBOR Rate may not be selected when
          ----------------                                                      
a Default or Potential Default exists and except as otherwise provided in this
agreement, Borrowings bear interest at an annual rate equal to the lesser of
either (a) the Base Rate plus the Applicable Margin or the LIBOR Rate plus the
Applicable Margin (in each case as designated or deemed designated by Borrower),
as the case may be, or (b) the Maximum Rate.  Each change in the Base Rate and
Maximum Rate is effective, without notice to Borrower or any other Person, upon
the effective date of change.

     3.4  Quotation of Rates.  Borrower may call Agent before delivering a
          ------------------                                              
Borrowing Request to receive an indication of the interest rates then in effect,
but the indicated rates do not bind Agent or Lenders or affect the interest rate
that is actually in effect when Borrower makes a Borrowing request or on the
Borrowing Date.

     3.5  Default Rate.  If permitted by Law, all past-due Principal Debt,
          ------------                                                    
Borrower's past-due payment and reimbursement obligations in connection with
LCs, and past-due interest accruing on

                                       21
<PAGE>
 
any of the foregoing bears interest from the date due (stated or by
acceleration) at the Default Rate until paid, regardless whether payment is made
before or after entry of a judgment.

     3.6  Interest Recapture.  If the designated interest rate applicable to any
          ------------------                                                    
Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is
limited to the Maximum Rate, but any subsequent reductions in the designated
rate shall not reduce the interest rate thereon below the Maximum Rate until the
total amount of accrued interest equals the amount of interest that would have
accrued if that designated rate had always been in effect.  If at maturity
(stated or by acceleration), or at final payment of the Notes, the total
interest paid or accrued is less than the interest that would have accrued if
the designated rates had always been in effect, then, at that time and to the
extent permitted by Law, Borrower shall pay an amount equal to the difference
between (a) the lesser of the amount of interest that would have accrued if the
designated rates had always been in effect and the amount of interest that would
have accrued if the Maximum Rate had always been in effect, and (b) the amount
of interest actually paid or accrued on the Notes.

     3.7  Interest Calculations.  Interest will be calculated on the basis of
          ---------------------                                              
actual number of days (including the first day but excluding the last day)
elapsed but computed as if each calendar year consisted of 360 days (unless the
calculation would result in an interest rate greater than the Maximum Rate or in
the case of interest on Base-Rate Borrowings in which event interest will be
calculated on the basis of a year of 365 or 366 days, as the case may be).  All
interest rate determinations and calculations by Agent are conclusive and
binding absent manifest error.

     3.8  Maximum Rate.  Regardless of any provision contained in any Loan
          ------------                                                    
Document, no Lender is entitled to contract for, charge, take, reserve, receive,
or apply, as interest on all or any part of the Obligation, any amount in excess
of the Maximum Rate, and, if Lenders ever do so, then any excess shall be
treated as a partial prepayment of principal and any remaining excess shall be
refunded to Borrower.  In determining if the interest paid or payable exceeds
the Maximum Rate, Borrower and Lenders shall, to the maximum extent permitted
under applicable Law, (a) treat all Borrowings as but a single extension of
credit (and Lenders and Borrower agree that is the case and that provision in
this agreement for multiple Borrowings is for convenience only), (b)
characterize any nonprincipal payment as an expense, fee, or premium rather than
as interest, (c) exclude voluntary prepayments and their effects, and (d)
amortize, prorate, allocate, and spread the total amount of interest throughout
the entire contemplated term of the Obligation.  However, if the Obligation are
paid in full before the end of their full contemplated term, and if the interest
received for its actual period of existence exceeds the Maximum Amount, Lenders
shall refund any excess (and Lenders may not, to the extent permitted by Law, be
subject to any penalties provided by any Laws for contracting for, charging,
taking, reserving, or receiving interest in excess of the Maximum Amount).  If
the Laws of the State of Texas are applicable for purposes of determining the
"Maximum Rate" or the "Maximum Amount," then those terms mean the "indicated
rate ceiling" from time to time in effect under Article 5069-1.04, Title 79,
Revised Civil Statutes of Texas, as amended.  Borrower agrees that Chapter 15,
Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended (which regulates
certain revolving credit loan accounts and revolving triparty accounts), does
not apply to the Obligation.

     3.9  Interest Periods.  When Borrower requests any LIBOR-Rate Borrowing,
          ----------------                                                   
Borrower may elect the applicable interest period (each an "INTEREST PERIOD"),
which may be, at Borrower's option, one, two, three, or six months for LIBOR-
Rate Borrowings, subject to SECTION 14.1 and the following conditions:  (a) the
initial Interest Period for a LIBOR-Rate Borrowing commences on the applicable
Borrowing Date or conversion date, and each subsequent Interest Period
applicable to any Borrowing commences on the day when the next preceding
applicable Interest Period expires; (b) if any Interest Period for a LIBOR-Rate
Borrowing begins on a day for which no numerically corresponding Business Day in
the calendar month at the end of the Interest Period exists, then the Interest
Period ends on the last Business Day of that calendar month; (c) if Borrower is
required to pay any of a LIBOR-Rate

                                       22
<PAGE>
 
Borrowing before the end of its Interest Period in order to comply with the
payment provisions of the Loan Documents, Borrower shall also pay any related
Funding Loss; and (d) no more than five Interest Periods may be in effect at one
time.

     3.10 Conversions.  Subject to the dollar limits of SECTION 2.1 and
          -----------                                                  
provided that Borrower may not convert to or select a new Interest Period for a
LIBOR-Rate Borrowing at any time when a Default or Potential Default exists,
Borrower may (a) convert a LIBOR-Rate Borrowing on the last day of the
applicable Interest Period to a Base-Rate Borrowing, (b) convert a Base-Rate
Borrowing at any time to a LIBOR-Rate Borrowing, and (c) elect a new Interest
Period for a LIBOR-Rate Borrowing. That election may be made by telephonic
request to Agent no later than 11:00 a.m. on the third Business Day before the
conversion date or the last day of the Interest Period, as the case may be (for
conversion to a LIBOR-Rate Borrowing or election of a new Interest Period), and
no later than 11:00 a.m. on the last day of the Interest Period (for conversion
to a Base-Rate Borrowing).  Borrower shall provide a Conversion Notice to Agent
no later than two days after the date of the conversion or election.  Absent
Borrower's telephonic request for conversion or election of a new Interest
Period or if a Default or Potential Default exists, then, a LIBOR-Rate Borrowing
shall be deemed converted to a Base-Rate Borrowing effective when the applicable
Interest Period expires.

     3.11 Order of Application.
          -------------------- 

          (a) No Default.  If no Default or Potential Default exists, any
              ----------                                                 
     payment shall be applied to the Obligation -- except as otherwise
     specifically provided in the Loan Documents --in the order and manner as
     Borrower directs.

          (b) Default.  If a Default or Potential Default exists or if Borrower
              -------                                                          
     fails to give direction, any payment (including proceeds from the exercise
     of any Rights) shall be applied in the following order:  (i) To all fees
     and expenses for which Agent or Lenders have not been paid or reimbursed in
     accordance with the Loan Documents (and if such payment is less than all
     unpaid or unreimbursed fees and expenses, then the payment shall be paid
     against unpaid and unreimbursed fees and expenses in the order of
     incurrence or due date); (ii) to accrued interest on the Principal Debt;
     (iii) to any LC reimbursement obligations that are due and payable and that
     remain unfunded by any Borrowing under the Revolving Facility; (iv) to the
     remaining Principal Debt in the order as Determining Lenders may elect (but
     Determining Lenders agree to apply proceeds in an order that will minimize
     any Funding Loss); (v) to the remaining Obligation in the order and manner
     Determining Lenders deem appropriate; and (vi) as a deposit with Agent, for
     the benefit of Lenders, as security for and payment of any subsequent LC
     reimbursement obligations.

          (c) Pro Rata.  Each payment or prepayment shall be distributed to each
              --------                                                          
     Lender in accordance with its Pro Rata Part of that payment or prepayment.

     3.12 Sharing of Payments, Etc.  If any Lender obtains any payment or
          -------------------------                                      
prepayment with respect to the Obligation (whether voluntary, involuntary, or
otherwise, including, without limitation, as a result of exercising its Rights
under SECTION 3.13) that exceeds the part of that payment or prepayment that it
is then entitled to receive under the Loan Documents, then that Lender shall
purchase from the other Lenders participations that will cause the purchasing
Lender to share the excess payment or prepayment ratably with each other Lender.
If all or any portion of any excess payment or prepayment is subsequently
recovered from the purchasing Lender, then the purchase shall be rescinded and
the purchase price restored to the extent of the recovery.  Borrower agrees that
any Lender purchasing a participation from another Lender under this section
may, to the fullest extent permitted by Law, exercise all of its Rights of
payment (including the Right of offset) with

                                       23
<PAGE>
 
respect to that participation as fully as if that Lender were the direct
creditor of Borrower in the amount of that participation.

     3.13 Offset.  If a Default exists, each Lender is entitled to exercise
          ------                                                           
(for the benefit of all Lenders in accordance with SECTION 3.12) the Rights of
offset and banker's Lien against each and every account and other property, or
any interest therein, that any Company may now or hereafter have with, or which
is now or hereafter in the possession of, that Lender to the extent of the full
amount of the Obligation owed (directly or participated) to it.

     3.14 Booking Borrowings.  To the extent permitted by Law, any Lender may
          ------------------                                                 
make, carry, or transfer its Borrowings at, to, or for the account of any of its
branch offices or the office or branch of any of its Affiliates.  However, no
Affiliate or branch is entitled to receive any greater payment under SECTION
3.16 than the transferor Lender would have been entitled to receive with respect
to those Borrowings, and a transfer may not be made if, as a direct result of
it, SECTION 3.15 or 3.17 would apply to any of the Obligation.  If any of the
conditions of SECTIONS 3.16 or 3.17 ever apply to a Lender, that Lender shall
carry or transfer its Borrowings at, to, or for the account of any of its branch
offices or the office or branch of any of its Affiliates so long as the transfer
is consistent with the other provisions of this section, does not create any
burden or adverse circumstance for that Lender that would not otherwise exist,
and eliminates the conditions of SECTIONS 3.16 or 3.17 as applicable.

     3.15 Basis Unavailable or Inadequate for LIBOR Rate.  If, on or before
          ----------------------------------------------                   
any date when a LIBOR Rate is to be determined for a Borrowing, Agent reasonably
determines that the basis for determining the applicable rate is not available
or any Lender reasonably determines that the resulting rate does not accurately
reflect the cost to that Lender of making or converting Borrowings at that rate
for the applicable Interest Period, then Agent shall promptly notify Borrower
and Lenders of that determination (which is conclusive and binding on Borrower
absent manifest error) and the applicable Borrowing shall bear interest at the
sum of the Base Rate plus the Applicable Margin. Until Agent notifies Borrower
that those circumstances no longer exist, Lenders' commitments under this
agreement to make, or to convert to, LIBOR-Rate Borrowings, as the case may be,
are suspended.

     3.16 Additional Costs.  Each Lender severally and not jointly agrees to
          ----------------                                                  
notify Agent, the other Lenders, and Borrower within 90 days after it has actual
knowledge that any circumstances exist that would give rise to any payment
obligation by Borrower under CLAUSES (A) through (C) below. Although no Lender
shall have any liability to Agent, any other Lender, or any Company for its
failure to give that notice, Borrower is not obligated to pay any amounts under
those clauses that arise, accrue, or are imposed more than 90 days before that
notice to the extent it is applicable to those amounts.  Any Lender demanding
payment of any additional costs under this section must generally be making
similar demand for similar additional costs under credit agreements to which it
is party that contain similar provisions to this section.

          (a) Reserves.  With respect to any or LIBOR-Rate Borrowing (i) if any
              --------                                                         
     present or future Law imposes, modifies, or deems applicable (or if
     compliance by any Lender with any requirement of any Tribunal results in)
     any requirement that any reserves (including, without limitation, any
     marginal, emergency, supplemental, or special reserves) be maintained
     (other than any reserve included in the Reserve Requirement), and if (ii)
     those reserves reduce any sums receivable by that Lender under this
     agreement or increase the costs incurred by that Lender in advancing or
     maintaining any portion of any LIBOR-Rate Borrowing, then (iii) that Lender
     (through Agent) shall deliver to Borrower a certificate setting forth in
     reasonable detail the calculation of the amount necessary to compensate it
     for its reduction or increase (which certificate is conclusive and binding
     absent manifest error), and (iv) Borrower shall pay that amount to that
     Lender within five Business Days after demand.  The provisions of and

                                       24
<PAGE>
 
     undertakings and indemnification in this CLAUSE (A) survive the
     satisfaction and payment of the Obligation and termination of this
     agreement.

          (b) Capital Adequacy.  With respect to any Commitment, Borrowing or LC
              ----------------                                                  
     if any present or future Law regarding capital adequacy or compliance by
     Agent (as issuer of LCs) or any Lender with any request, directive, or
     requirement now existing or hereafter imposed by any Tribunal regarding
     capital adequacy, or any change in its written policies or in the risk
     category of this transaction, reduces the rate of return on its capital as
     a consequence of its obligations under this agreement to a level below that
     which it otherwise could have achieved (taking into consideration its
     policies with respect to capital adequacy) by an amount deemed by it to be
     material (and it may, in determining the amount, utilize reasonable
     assumptions and allocations of costs and expenses and use any reasonable
     averaging or attribution method in apportioning such costs to its customers
     generally), then (unless the effect is already reflected in the rate of
     interest then applicable under this agreement) Agent or that Lender
     (through Agent) shall notify Borrower and deliver to Borrower a certificate
     setting forth in reasonable detail the calculation of the amount necessary
     to compensate it (which certificate is conclusive and binding absent
     manifest error), and Borrower shall pay that amount to Agent or that Lender
     within five Business Days after demand.  The provisions of and undertakings
     and indemnification in this CLAUSE (B) shall survive the satisfaction and
     payment of the Obligation and termination of this agreement.

          (c) Taxes.  Subject to SECTION 3.19, any Taxes payable by Agent or any
              -----                                                             
     Lender or ruled (by a Tribunal) payable by Agent or any Lender in respect
     of this agreement or any other Loan Document shall, if permitted by Law, be
     paid by Borrower, together with interest and penalties, if any  except for
     Taxes payable on or measured by the overall net income of Agent or that
     Lender (or Agent or that Lender, as the case may be, together with any
     other Person with whom Agent or that Lender files a consolidated, combined,
     unitary, or similar Tax return) and except for interest and penalties
     incurred as a result of the gross negligence or willful misconduct of Agent
     or any Lender).  Agent or that Lender (through Agent) shall notify Borrower
     and deliver to Borrower a certificate setting forth in reasonable detail
     the calculation of the amount of payable Taxes, which certificate is
     conclusive and binding (absent manifest error), and Borrower shall pay that
     amount to Agent for its account or the account of that Lender, as the case
     may be within five Business Days after demand.  If Agent or that Lender
     subsequently receives a refund of the Taxes paid to it by Borrower, then
     the recipient shall promptly pay the refund to Borrower.

     3.17 Change in Laws.  If any Law makes it unlawful for any Lender to make

or maintain LIBOR-Rate Borrowings, then that Lender shall promptly notify
Borrower and Agent, and (a) as to undisbursed funds, that requested Borrowing
shall be made as a Base-Rate Borrowing, and (b) as to any outstanding Borrowing
(i) if maintaining the Borrowing until the last day of the applicable Interest
Period is unlawful, the Borrowing shall be converted to a Base-Rate Borrowing as
of the date of notice, in which event Borrower will not be required to pay any
related Funding Loss, or (ii) if not prohibited by Law, the Borrowing shall be
converted to a Base-Rate Borrowing as of the last day of the applicable Interest
Period, or (iii) if any conversion will not resolve the unlawfulness, Borrower
shall promptly prepay the Borrowing, without penalty but with related Funding
Loss.

     3.18 FUNDING LOSS.  BORROWER SHALL INDEMNIFY EACH LENDER AGAINST, AND PAY
          ------------                                                        
TO IT UPON DEMAND, ANY FUNDING LOSS OF THAT LENDER.  WHEN ANY LENDER DEMANDS
THAT BORROWER PAY ANY FUNDING LOSS, THAT LENDER SHALL DELIVER TO BORROWER AND
AGENT A CERTIFICATE SETTING FORTH IN REASONABLE DETAIL THE BASIS FOR IMPOSING
FUNDING LOSS AND THE CALCULATION OF THE AMOUNT, WHICH CALCULATION IS CONCLUSIVE
AND BINDING ABSENT MANIFEST ERROR.  THE PROVISIONS OF AND UNDERTAKINGS AND

Participant (by accepting a participation interest under this agreement), and
Assignee (by executing an Assignment) that is not organized under the Laws of
the United States of America or one of its states (a) represents to Agent and
Borrower that (i) no Taxes are required to be withheld by Agent or Borrower with
respect to any payments to be made to it in respect of the Obligation and (ii)
it has furnished to Agent and Borrower two duly completed copies of either U.S.
Internal Revenue Service Form 4224, Form 1001, Form W-8, or any other form
acceptable to Agent and Borrower that entitles it to a complete exemption from
U.S. federal withholding Tax on all interest payments under the Loan Documents,
and (b) covenants to (i) provide Agent and Borrower a new Form 4224, Form 1001,
Form W-8, or other form acceptable to Agent upon the expiration or obsolescence
according to Law of any previously delivered form, duly executed and completed
by it, entitling it to a complete exemption from U.S. federal withholding Tax on
all interest and fee payments under the Loan Documents, and (ii) comply from
time to time with all Laws with regard to the withholding Tax exemption.  If any
of the foregoing is not true at any time or the applicable forms are not
provided, then Borrower and Agent (without duplication) may deduct and withhold
from interest and fee payments under the Loan Documents any Tax at the maximum
rate under the Code or other applicable Law, and amounts so deducted and
withheld shall be treated as paid to that Lender for all purposes under the Loan
Documents.

     5.1  Guaranty.  Borrower shall cause XPLOR and all of XPLOR's present and
          --------

          (a) all of the Mineral Interests described in Exhibit B attached
                                                        ---------         
hereto and all other Mineral Interests hereafter included in the calculation of
the Borrowing Base and the oil, gas and mineral production therefrom or
attributable thereto, and in all operating agreements and oil or gas purchase
contracts (now existing or hereafter arising) relating to such Mineral Interests
and in related personal properties, fixtures and other properties, pursuant to
mortgages, deeds of trust, assignments of production, security agreements,
financing statements and other documents satisfactory to Agent;

          (b) all of the present and future issued and outstanding capital stock

     5.3  Collateral Account.  In order to secure further the performance by
          ------------------                                                
Borrower of the Obligation and to effect and facilitate Agent's right of offset,
immediately following Agent's request, Borrower shall, and shall cause the other
Companies to execute such forms, authorizations, documents and instruments, and
do such other things, as Agent shall request, in order to require that pipeline
companies, operators of the Mortgaged Properties and others (collectively, the
"Purchasers") purchasing (or acting as agents for, or making payments on behalf
 ----------                                                                    
of, those purchasing) the oil, gas and other minerals produced or to be produced
from, or relating to, the Mineral Interests deliver to a post office box number
specified by Agent all royalties, production payments, checks, cash, proceeds
and monies now or hereafter payable by the Purchasers (or any of them) on
account of oil, gas or other minerals produced from or relating to the Mineral
Interests  or otherwise with respect to the Mineral Interests; provided that
Agent shall not deliver any such forms or documents to any Purchaser or
otherwise notify or request any Purchaser to so deliver such proceeds unless and
until a Default shall have occurred.  Borrower agrees that all such royalties,
payments and monies delivered to such post office box shall be deposited by
Agent in a cash collateral account at Agent styled "Araxas Production Account."
After the occurrence of a Default, Borrower shall, and shall cause the other
Companies to, upon receipt, deposit in the Araxas Production Account all such
royalties, payments and monies which Borrower or any other Company receives
directly from the Purchasers.  Borrower hereby irrevocably authorizes and
directs Agent to charge from time to time after the occurrence of a Default, the
Araxas Production Account and any other accounts of Borrower at Agent or any
Lender for amounts due to the Lenders hereunder and under the Notes.  After the
occurrence of a Default, Agent is hereby authorized, in its own name or the name
of the Borrower, to notify any or all parties obligated to Borrower with respect
to the Mineral Interests to make all payments due or to become due thereon
directly to the Agent, or such other person or officer as Agent may require
whereupon the power and authority of the Borrower to collect the same in the
ordinary course of its business shall be deemed to be immediately revoked and
terminated.  With or without such general notification, after the occurrence of
a Default, Agent may take or bring in Borrower's name or that of the Agent all
steps, actions, suits or proceedings deemed by the Agent necessary or desirable
to effect possession or collection of payments, may complete any contract or
agreement of the Borrower in any way related to any of the Mineral Interests,
may make allowances or adjustments related to the Mineral Interests, may
compromise any claims related to the Mineral Interests or may issue credit in
its own name or the name of the Borrower.  Regardless of any provision hereof,
however, Agent shall never be liable for its failure to collect or for its
failure to exercise diligence in the collection, possession, or any transaction
concerning, all or part of the Mineral Interests or sums due or paid thereon,
nor shall it or they be under any obligation whatsoever to anyone by virtue of
its security interests and liens relating to the Mortgaged Properties.

     The Agent is hereby authorized and empowered on behalf of the Borrower to
endorse the name of the Borrower upon any check, draft, instrument, receipt,
instruction or other document or items, including, but not limited to, all items
evidencing payment upon any indebtedness of any Person to the Borrower coming
into the Agent's possession, and to receive and apply the proceeds therefrom in
accordance with the terms hereof.  The Agent is hereby granted an irrevocable
power of attorney, which is coupled with an interest, to execute all checks,
drafts, receipts, instruments, instructions or other documents, agreements or
items on behalf of the Borrower, either before or after demand of payment on the
Notes, as shall be deemed by the Agent to be necessary or advisable, in the sole
discretion of the Agent, to protect its security interests and liens in the
Mineral Interests or the repayment of the Obligation, and the Agent shall not
incur any liability in connection with or arising from its exercise of such
power of attorney.

     Borrower acknowledges that all funds so transferred into the Araxas
Production Account shall be the property of the Borrower and the other Companies
only and not subject to any claim by any party other than Agent, for the benefit
of the Lenders.

     5.4  Further Assurances.  Borrower covenants and agrees that the Lender
          ------------------                                                
Liens otherwise described in SECTION 5.2 and, when required, SECTION 2.3(G) and
5.3 must be created and perfected as a condition to funding any Borrowings or
the issuance of any LC.  Furthermore, Borrower shall --and shall cause each
other appropriate Company to -- perform the acts, duly authorize, execute,
acknowledge, deliver, file, and record any additional writings, and pay all
filings fees and costs as Agent or Determining Lenders may reasonably deem
appropriate or necessary to perfect and maintain the Lender Liens and preserve
and protect the Rights of Agent and Lenders under any Loan Document.

     5.5  Release of Collateral.
          --------------------- 

          (a) Whenever no Lender has any commitment to extend credit under any
     Loan Document and the Obligation has been fully paid and performed, Agent
     shall, upon Borrower's written request and at Borrower's cost and expense,
     cause the Lender Liens on all Collateral to be released.

          (b) In connection with any sale or other disposition of assets
     permitted by SECTION 9.10, Agent shall, upon Borrower's request and at
     Borrower's cost and expense, release the Lender Liens on the assets sold or
     disposed of.

          (c) If the Facility Conversion Date shall have occurred, Agent shall,
     at Borrower's cost and expense, execute and deliver all documents and
     instruments reasonably necessary to release and terminate all Lender Liens
     on any of the Material Prospects not then comprising a portion of the
     Borrowing Base within a reasonable time of Borrower's request therefor.

SECTION 6.  CONDITIONS PRECEDENT.  No Lender is obligated to fund the initial
- ----------  --------------------                                             
Borrowing or issue the initial LC under the Bridge Facility unless Agent has
received all of the items described in PART A on SCHEDULE 6.  No Lender is
obligated to fund the initial Borrowing (including any deemed Borrowings
pursuant to SECTION 2.1(B)(V) or issue any LC under the Revolving Facility
unless all Facility Conversion Conditions have been completely fulfilled to the
satisfaction of Agent, in the exercise of its sole discretion.  In addition, no
Lender is obligated to fund (as opposed to continue or convert) any Borrowing or
issue any LC unless on the applicable Borrowing Date, or issue date (and after
giving effect to the requested Borrowing or LC), as the case may be:  (a) Agent
(and the Issuing Lender, if applicable) timely receives a Borrowing Request or
LC Request (together with the applicable LC Agreement), as the case may be; (b)
the Issuing Lender receives any applicable LC fee or other amounts then due and
payable with respect to any LC; (c) all of the representations and warranties of
the Companies in the Loan Documents are true and correct in all material
respects (unless they speak to a specific date or are based on facts which have
changed by transactions contemplated or expressly permitted by this agreement);
(d) no Material Adverse Event, Default, or Potential Default exists; (e) no
Borrowing-Base Deficiency will exist after giving effect to the Borrowing or LC
issuance; and (f) no limitation in SECTION 2.1 or 2.3 is exceeded.  Each
Borrowing Request and LC Request, however delivered, constitutes Borrower's
representation and warranty that the conditions in CLAUSES (C) through (F) above
are satisfied.  Upon Agent's or any Lender's reasonable request, Borrower shall
deliver to Agent or such Lender evidence substantiating any of the matters in
the Loan Documents that are necessary to enable Borrower to qualify for the
Borrowing or LC, as the case may be.  Each condition precedent in this agreement
(including, without limitation, those on SCHEDULE 6) is material to the
transactions contemplated by this agreement, and time is of the essence with
respect to each condition precedent.

of the following:

     11.1 Payment of Obligation. Borrower's failure or refusal to pay (a)
          ---------------------

     11.6  Misrepresentation.  Any material representation or warranty made by
           -----------------                                                  
any Company in any Loan Document at any time proves to have been materially
incorrect when made.

     11.7  Ownership of Companies. Except as a result of transactions permitted
           ----------------------                                     
by this agreement, one or more Restricted Companies fail to own, beneficially
and of record, with power to vote, 100% of the issued and outstanding shares of
capital stock of each other Restricted Company other than XPLOR.

     11.8  Change of Control of Borrower.  The individuals who, as of the date

purposes of this SECTION 11.8, the "INCUMBENT BOARD") do not constitute or cease

           ---------------------------

SECTION 12. RIGHTS AND REMEDIES.
- ----------- -------------------- 

     12.1   Remedies Upon Default.
            --------------------- 
 
            (a) Debtor Relief.  If a Default exists under SECTION 11.3, the
                -------------                                              
     commitment to extend credit under this agreement automatically terminates,
     the entire unpaid balance of the Obligation automatically becomes due and
     payable without any action of any kind whatsoever.

            (b) Other Defaults.  If any Default exists, subject to the terms of
                --------------                                                 
     SECTION 13.5(B), Agent may (with the consent of, and must, upon the request
     of, Determining Lenders), do any one or more of the following:  (i) If the
     maturity of the Obligation has not already been accelerated under SECTION
     12.1(A), declare the entire unpaid balance of all or any part of the
     Obligation immediately due and payable, whereupon it is due and payable;
     (ii) terminate the commitments of Lenders to extend credit under this
     agreement; (iii) reduce any claim to judgment; (iv) demand payment of an
     amount equal to the LC Exposure then existing and retain as collateral for
     the LC Exposure any amounts received from any Company, from any property of
     any Company, through offset, or otherwise; and (v) exercise any and all
     other legal or equitable Rights afforded by the Loan Documents, by
     applicable Laws, or in equity.

            (c) Offset.  If a Default exists, to the extent permitted by
                ------                                                  
     applicable Law, each Lender may exercise the Rights of offset and banker's
     lien against each and every account and other property, or any interest
     therein, which any Restricted Company may now or hereafter have with, or
     which is now or hereafter in the possession of, that Lender to the extent
     of the full amount of the Obligation owed to that Lender.

            (d) Production Proceeds. Notify any and all purchasers of production
                -------------------
     and take all other actions specified in SECTION 5.3 of this agreement.

     12.2   Company Waivers.  To the extent permitted by Law, Borrower and
            ---------------                                               
(pursuant to its Guaranty) each other Restricted Company waives presentment and
demand for payment, protest, notice of intention to accelerate, notice of
acceleration, and notice of protest and nonpayment, and agrees that its
liability with respect to all or any part of the Obligation is not affected by
any renewal

                                       45
<PAGE>
 
or extension in the time of payment of all or any part of the Obligation, by any
indulgence, or by any release or change in any security for the payment of all
or any part of the Obligation.

      12.3  Performance by Agent.  If any Company's covenant, duty, or agreement
            --------------------                                                
is not performed in accordance with the terms of the Loan Documents, Agent may,
while a Default exists, at its option (but subject to the approval of
Determining Lenders), perform or attempt to perform that covenant, duty, or
agreement on behalf of that Company (and any amount expended by Agent in its
performance or attempted performance is payable by the Companies, jointly and
severally, to Agent on demand, becomes part of the Obligation, and bears
interest at the Default Rate from the date of Agent's expenditure until paid).
However, Agent does not assume and shall never have, except by its express
written consent, any liability or responsibility for the performance of any
Company's covenants, duties, or agreements.

      12.4  Not in Control.  Nothing in any Loan Document gives or may be deemed
            --------------                                                      
to give to Agent or any Lender the Right to exercise control over any Company's
Real Property (including, without limitation, the Leases and the Mineral
Interests), other assets, affairs, or management or to preclude or interfere
with any Company's compliance with any Law or require any act or omission by any
Company that may be harmful to Persons or property.  Any "Material Adverse
Event" or other materiality or substantiality qualifier of any representation,
warranty, covenant, agreement, or other provision of any Loan Document is
included for credit documentation purposes only and does not imply or be deemed
to mean that Agent or any Lender acquiesces in any non-compliance by any Company
with any Law, document, or otherwise or does not expect the Companies to
promptly, diligently, and continuously carry out all appropriate removal,
remediation, compliance, closure, or other activities required or appropriate in
accordance with all Environmental Laws.  Agent's and Lenders' power is limited
to the Rights provided in the Loan Documents.  All of those Rights exist solely
- -- and may be exercised in manner calculated by Agent or Lenders in their
respective good faith business judgment --to preserve and protect the Collateral
and to assure payment and performance of the Obligation.

      12.5  Course of Dealing.  The acceptance by Agent or Lenders of any
            -----------------                                            
partial payment on the Obligation is not a waiver of any Default then existing.
No waiver by Agent, Determining Lenders, or Lenders of any Default is a waiver
of any other then-existing or subsequent Default.  No delay or omission by
Agent, Determining Lenders, or Lenders in exercising any Right under the Loan
Documents impairs that Right or is a waiver thereof or any acquiescence therein,
nor will any single or partial exercise of any Right preclude other or further
exercise thereof or the exercise of any other Right under the Loan Documents or
otherwise.

      12.6  Cumulative Rights.  All Rights available to Agent, Determining
            -----------------                                             
Lenders, and Lenders under the Loan Documents are cumulative of and in addition
to all other Rights granted to Agent, Determining Lenders, and Lenders at law or
in equity, whether or not the Obligation are due and payable and whether or not
Agent, Determining Lenders, or Lenders have instituted any suit for collection,
foreclosure, or other action in connection with the Loan Documents.

      12.7  Application of Proceeds.  Any and all proceeds ever received by
            -----------------------                                        
Agent or Lenders from the exercise of any Rights pertaining to the Obligation
shall be applied to the Obligation according to SECTION 3.

      12.8  Certain Proceedings.  Borrower shall promptly execute and deliver,
            -------------------                                               
or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers Agent
or Determining Lenders reasonably request in connection with the obtaining of
any consent, approval, registration (other than securities Law registrations
except as may otherwise be expressly provided in the Warrant Agreement),
qualification, permit, license, or authorization of any Tribunal or other Person
necessary or appropriate for the effective exercise of any

                                       46
<PAGE>
 
Rights under the Loan Documents.  Because Borrower agrees that Agent's and
Determining Lenders' remedies at Law for failure of Borrower to comply with the
provisions of this section would be inadequate and that failure would not be
adequately compensable in damages, Borrower agrees that the covenants of this
section may be specifically enforced.

      12.9  Expenditures by Lenders.  Any sums spent by Agent or any Lender in
            -----------------------                                           
the exercise of any Right under any Loan Document is payable by the Companies to
Agent within five Business Days after demand, becomes part of the Obligation,
and bears interest at the Default Rate from the date spent until the date
repaid.

      12.10 Diminution in Value of Collateral.  Neither Agent nor any Lender
            ---------------------------------                               
has any liability or responsibility whatsoever for any diminution in or loss of
value of any collateral now or in the future securing payment or performance of
any of the Obligation (other than diminution in or loss of value caused by its
own gross negligence or willful misconduct).

SECTION 13. AGENT AND LENDERS.
- ----------- ----------------- 

      13.1  Agent.
            ----- 

            (a) Appointment.  Each Lender appoints Agent (and Agent accepts
                -----------                                                
     appointment) as its nominee and agent, in its name and on its behalf:  (i)
     To act as its nominee and on its behalf in and under all Loan Documents;
     (ii) to arrange the means whereby its funds are to be made available to
     Borrower under the Loan Documents; (iii) to take any action that it
     properly requests under the Loan Documents (subject to the concurrence of
     other Lenders as may be required under the Loan Documents); (iv) to receive
     all documents and items to be furnished to it under the Loan Documents; (v)
     to be the secured party, mortgagee, beneficiary, recipient, and similar
     party in respect of any collateral for the benefit of Lenders; (vi) to
     promptly distribute to it all material information, requests, documents,
     and items received from Borrower under the Loan Documents; (vii) to
     promptly distribute to it its ratable part of each payment or prepayment
     (whether voluntary, as proceeds of collateral upon or after foreclosure, as
     proceeds of insurance thereon, or otherwise) in accordance with the terms
     of the Loan Documents; and (viii) to deliver to the appropriate Persons
     requests, demands, approvals, and consents received from it.  However,
     Agent may not be required to take any action that exposes it to personal
     liability or that is contrary to any Loan Document or applicable Law.

            (b) Successor. Agent may voluntarily resign and shall resign upon
                --------- 
     the request of Determining Lenders for cause (i.e., Agent is continuing to
     fail to perform its responsibilities as Agent under the Loan Documents). If
     the initial or any successor Agent ever ceases to be a party to this
     agreement or if the initial or any successor Agent ever resigns (whether
     voluntarily or at the request of Determining Lenders), then Determining
     Lenders shall (which, if no Default or Potential Default exists, is subject
     to Borrower's approval that may not be unreasonably withheld) appoint the
     successor Agent from among Lenders (other than the resigning Agent). If
     Determining Lenders fail to appoint a successor Agent within 30 days after
     the resigning Agent has given notice of resignation or Determining Lenders
     have removed the resigning Agent, then the resigning Agent may, on behalf
     of Lenders, appoint a successor Agent, which must be a commercial bank
     having a combined capital and surplus of at least $1,000,000,000 (as shown
     on its most recently published statement of condition). Upon its acceptance
     of appointment as successor Agent, the successor Agent succeeds to and
     becomes vested with all of the Rights of the prior Agent, and the prior
     Agent is discharged from its duties and obligations of Agent under the Loan
     Documents (but, when used in connection with LCs issued and outstanding
     before the appointment of the successor Agent, "Agent" shall continue to
     refer solely to the prior Agent -- but, any LCs issued or renewed after the

                                       47
<PAGE>
 
     appointment of any successor Agent shall be issued or renewed by the
     successor Agent), and each Lender shall execute the documents that any
     Lender, the resigning or removed Agent, or the successor Agent reasonably
     request to reflect the change.  After any Agent's resignation or removal as
     Agent under the Loan Documents, the provisions of this section inure to its
     benefit as to any actions taken or not taken by it while it was Agent under
     the Loan Documents.

          (c) Rights as Lender.  Agent, in its capacity as a Lender, has the
              ----------------                                              
     same Rights under the Loan Documents as any other Lender and may exercise
     those Rights as if it were not acting as Agent.  The term "Lender", unless
     the context otherwise indicates, includes Agent.  Agent's resignation or
     removal does not impair or otherwise affect any Rights that it has or may
     have in its capacity as an individual Lender.  Each Lender and Borrower
     agree that Agent is not a fiduciary for Lenders or for Borrower but is
     simply acting in the capacity described in this agreement to alleviate
     administrative burdens for Borrower and Lenders, that Agent has no duties
     or responsibilities to Lenders or Borrower except those expressly set forth
     in the Loan Documents, and that Agent in its capacity as a Lender has the
     same Rights as any other Lender.

          (d) Other Activities.  Agent or any Lender may now or in the future be
              ----------------                                                  
     engaged in one or more loan, letter of credit, leasing, or other financing
     transactions with Borrower, act as trustee or depositary for Borrower, or
     otherwise be engaged in other transactions with Borrower (collectively, the
     "OTHER ACTIVITIES") not the subject of the Loan Documents.  Without
     limiting the Rights of Lenders specifically set forth in the Loan
     Documents, neither Agent nor any Lender is responsible to account to the
     other Lenders for those other activities, and no Lender shall have any
     interest in any other Lender's activities, any present or future guaranties
     by or for the account of Borrower that are not contemplated by or included
     in the Loan Documents, any present or future offset exercised by Agent or
     any Lender in respect of those other activities, any present or future
     property taken as security for any of those other activities, or any
     property now or hereafter in Agent's or any other Lender's possession or
     control that may be or become security for the obligations of Borrower
     arising under the Loan Documents by reason of the general description of
     indebtedness secured or of property contained in any other agreements,
     documents, or instruments related to any of those other activities (but, if
     any payments in respect of those guaranties or that property or the
     proceeds thereof is applied by Agent or any Lender to reduce the
     Obligation, then each Lender is entitled to share ratably in the
     application as provided in the Loan Documents).

     13.2  Expenses.  Each Lender shall pay its Pro Rata Part of any reasonable
           --------                                                            
expenses (including, without limitation, court costs, reasonable attorneys' fees
and other costs of collection) incurred by Agent (while acting in such capacity)
in connection with any of the Loan Documents if Agent is not reimbursed from
other sources within 30 days after incurrence.  Each Lender is entitled to
receive its Pro Rata Part of any reimbursement that it makes to Agent if Agent
is subsequently reimbursed from other sources.

     13.3  Proportionate Absorption of Losses.  Except as otherwise provided in
           ----------------------------------                                  
the Loan Documents, nothing in the Loan Documents gives any Lender any advantage
over any other Lender insofar as the Obligation is concerned or relieves any
Lender from ratably absorbing any losses sustained with respect to the
Obligation (except to the extent unilateral actions or inactions by any Lender
result in Borrower or any other obligor on the Obligation having any credit,
allowance, setoff, defense, or counterclaim solely with respect to all or any
part of that Lender's Pro Rata Part of the Obligation).

     13.4 Delegation of Duties; Reliance.  Lenders may perform any of their
          ------------------------------                                   
duties or exercise any of their Rights under the Loan Documents by or through
Agent, and Lenders and Agent may perform any of their duties or exercise any of
their Rights under the Loan Documents by or through their respective
Representatives.  Agent, Lenders, and their respective Representatives (a) are
entitled to rely upon (and shall be protected in relying upon) any written or
oral statement believed by it or them to be genuine and correct and to have been
signed or made by the proper Person and, with respect to legal matters, upon
opinion of counsel selected by Agent or that Lender (but nothing in this CLAUSE
(A) permits Agent to rely on (i) oral statements if a writing is required by
this agreement or (ii) any other writing if a specific writing is required by
this agreement), (b) are entitled to deem and treat each Lender as the owner and
holder of its portion of the Obligation for all purposes until, written notice
of the assignment or transfer is given to and received by Agent (and any
request, authorization, consent, or approval of any Lender is conclusive and
binding on each subsequent holder, assignee, or transferee of or Participant in
that Lender's portion of the Obligation until that notice is given and
received), (c) are not deemed to have notice of the occurrence of a Default
unless a responsible officer of Agent, who handles matters associated with the
Loan Documents and transactions thereunder, has actual knowledge or Agent has
been notified by a Lender or Borrower, and (d) are entitled to consult with
legal counsel (including counsel for Borrower), independent accountants, and
other experts selected by Agent and are not liable for any action taken or not
taken in good faith by it in accordance with the advice of counsel, accountants,
or experts.

     13.5 Limitation of Agent's Liability.
          ------------------------------- 

          (a)  Exculpation.  Neither Agent nor any of its Representatives will
               -----------                                                    
     be liable for any action taken or omitted to be taken by it or them under
     the Loan Documents in good faith and believed by it or them to be within
     the discretion or power conferred upon it or them by the Loan Documents or
     be responsible for the consequences of any error of judgment (except for
     fraud, gross negligence, or willful misconduct), and neither Agent nor any
     of its representatives has a fiduciary relationship with any Lender by
     virtue of the Loan Documents (but nothing in this agreement negates the
     obligation of Agent to account for funds received by it for the account of
     any Lender).

          (b)  Indemnity.  Unless indemnified to its satisfaction against loss,
               ---------                                                       
     cost, liability, and expense, Agent may not be compelled to do any act
     under the Loan Documents or to take any action toward the execution or
     enforcement of the powers thereby created or to prosecute or defend any
     suit in respect of the Loan Documents. If Agent requests instructions from
     Lenders, or Determining Lenders, as the case may be, with respect to any
     act or action in connection with any Loan Document, Agent is entitled to
     refrain (without incurring any liability to any Person by so refraining)
     from that act or action unless and until it has received instructions. In
     no event, however, may Agent or any of its Representatives be required to
     take any action that it or they determine could incur for it or them
     criminal or onerous civil liability.  Without limiting the generality of
     the foregoing, no Lender has any right of action against Agent as a result
     of Agent's acting or refraining from acting under this agreement in
     accordance with instructions of Determining Lenders.

          (c)  Reliance.  Agent is not responsible to any Lender or any
               --------                                                
     Participant for, and each Lender represents and warrants that it has not
     relied upon Agent in respect of, (i) the creditworthiness of any Company
     and the risks involved to that Lender, (ii) the effectiveness,
     enforceability, genuineness, validity, or the due execution of any Loan
     Document (except by Agent), (iii) any representation, warranty, document,
     certificate, report, or statement made therein (except by Agent) or
     furnished thereunder or in connection therewith, (iv) the adequacy of any
     collateral now or hereafter securing the Obligation or the existence,
     priority, or perfection of any Lien now or hereafter granted or purported
     to be granted on the collateral

                                       49
<PAGE>
 
     under any Loan Document, or (v) observation of or compliance with any of
     the terms, covenants, or conditions of any Loan Document on the part of any
     Company.  EACH LENDER AGREES TO INDEMNIFY AGENT AND ITS REPRESENTATIVES AND
     HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S
     COMMITMENT PERCENTAGE OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
     DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES,
     AND REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE
     IMPOSED ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY WAY RELATING TO OR
     ARISING OUT OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM
     UNDER THE LOAN DOCUMENTS IF AGENT AND ITS REPRESENTATIVES ARE NOT
     REIMBURSED FOR SUCH AMOUNTS BY ANY COMPANY.  ALTHOUGH AGENT AND ITS
     REPRESENTATIVES HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR
     ITS OR THEIR OWN ORDINARY NEGLIGENCE, AGENT AND ITS REPRESENTATIVES DO NOT
     HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN
     FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT.

     13.6 Default.  While a Default exists, Lenders agree to promptly confer
          -------                                                           
in order that Determining Lenders or Lenders, as the case may be, may agree upon
a course of action for the enforcement of the Rights of Lenders.  Agent is
entitled to act or refrain from taking any action (without incurring any
liability to any Person for so acting or refraining) unless and until it has
received instructions from Determining Lenders.  In actions with respect to any
Company's property, Agent is acting for the ratable benefit of each Lender.

     13.7 Collateral Matters.
          ------------------ 

          (a) Each Lender authorizes and directs Agent to enter into the Loan
     Documents for the Lender Liens and agrees that any action taken by Agent
     concerning any Collateral (with the consent or at the request of
     Determining Lenders) in accordance with any Loan Document, that Agent's
     exercise (with the consent or at the request of Determining Lenders) of
     powers concerning the Collateral in any Loan Document, and that all other
     reasonably incidental powers are authorized and binding upon all Lenders.

          (b) Agent is authorized on behalf of all Lenders, without the
     necessity of any notice to or further consent from any Lender, from time to
     time before a Default or Potential Default, to take any action with respect
     to any Collateral or Loan Documents related to Collateral that may be
     necessary to perfect and maintain perfected the Lender Liens upon the
     Collateral.

          (c) Except to use the same standard of care that it ordinarily uses
     for collateral for its sole benefit, Agent has no obligation whatsoever to
     any Lender or to any other Person to assure that the Collateral exists or
     is owned by any Company or is cared for, protected, or insured or has been
     encumbered or that the Lender Liens have been properly or sufficiently or
     lawfully created, perfected, protected, or enforced or are entitled to any
     particular priority.

          (d) Agent shall exercise the same care and prudent judgment with
     respect to the Collateral and the Loan Documents as it normally and
     customarily exercises in respect of similar collateral and security
     documents.

          (e) Lenders irrevocably authorize Agent, at its option and in its
     discretion, to release any Lender Lien upon any Collateral (i) upon full
     payment of the Obligation, (ii) constituting property being disposed of as
     permitted under any Loan Document, (iii) constituting property in which no
     Company owned any interest at the time the Lender Lien was granted or at
     any time after that, (iv) constituting property leased to any Company under
     a lease that has expired or been terminated in a transaction permitted
     under the Loan

                                       50

     Documents or is about to expire and that has not been, and is not intended
     by that Company to be, renewed, (v) consisting of an instrument evidencing
     Debt pledged to Agent (for the benefit of Lenders), if the underlying Debt
     has been paid in full, or (vi) if approved, authorized, or ratified in
     writing by Lenders.  Upon request by Agent at any time, Lenders shall
     confirm in writing Agent's authority to release particular types or items
     of Collateral under this CLAUSE (E).

     13.8      Limitation of Liability.  No Lender or any Participant will incur
               -----------------------                                          
any liability to any other Lender or Participant except for acts or omissions in
bad faith, and neither Agent nor any Lender or Participant will incur any
liability to any other Person for any act or omission of any other Lender or any
Participant.

     13.9      Relationship of Lenders.  The Loan Documents do not create a
               -----------------------                                     
partnership or joint venture among Agent and Lenders or among Lenders.

     13.10     Benefits of Agreement.  None of the provisions of this section
               ---------------------                                         
inure to the benefit of any Company or any other Person except Agent and
Lenders.  Therefore, no Company or any other Person is responsible or liable
for, entitled to rely upon, or entitled to raise as a defense -- in any manner
whatsoever -- the failure of Agent or any Lender to comply with these
provisions.

SECTION 14.    MISCELLANEOUS.
- -----------    -------------- 

      14.1     Nonbusiness Days. Any payment or action that is due under any
               ----------------       
Loan Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a LIBOR-Rate
Borrowing, in which case if the next-succeeding Business Day is in the next
calendar month, then such payment shall be made on the next-preceding Business
Day.

      14.2     Communications.  Unless otherwise specifically provided, whenever
               --------------

by telex, when transmitted to the appropriate telex number and the appropriate

and Agent is stated beside their respective signatures to this agreement and for
each Lender is stated beside its name on SCHEDULE 2.

      14.3     Form and Number of Documents.  The form, substance, and number of
               ----------------------------                                     
counterparts of each writing to be furnished under this agreement must be

               -----------------------                                          
action that is permitted as an exception to any of the covenants contained in
any Loan Document if that action or omission would result in the breach of any
other covenant contained in any Loan Document.

      14.5     Survival. All covenants, agreements, undertakings,
               --------
representations, and warranties made in any of the Loan Documents survive all
closings under the Loan Documents and, except as otherwise indicated, are not
affected by any investigation made by any party.

      14.6  Governing Law.  Unless otherwise stated in any Loan Document, the
            -------------

illegal, invalid, or unenforceable is fully severable; the appropriate Loan
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision.  Agent, Lenders, and each
Company party to the affected Loan Document agree to negotiate, in good faith,
the terms of a replacement provision as similar to the severed provision as may
be possible and be legal, valid, and enforceable.

      14.8  Amendments, Consents, Conflicts, and Waivers.
            -------------------------------------------- 

            (a) Determining Lenders.  Unless otherwise specifically provided (i)
                -------------------                                             
     the provisions of this agreement may be amended, modified, or waived, only

     Loan Documents may only be the subject of an amendment, modification, or
     waiver that has been approved by Determining Lenders and Borrower.

            (b) All Lenders.  Any amendment to or consent or waiver under this
                -----------

     following must be by an instrument in writing executed by Borrower and
     Agent and executed (or approved, as the case may be) by each Lender: (i)

     Documents; (ii) decreases any rate or amount of interest, fees, or other
     sums payable to Agent or Lenders under this agreement (except such
     reductions as are contemplated by this agreement); (iii) changes the

     (vi) change the requirement that any redetermination of the Borrowing Base
     be approved and consented to by all of the Lenders; or (vii) changes this

                ------------------------------

     letter agreement must be in writing and executed only by Agent and
     Borrower, and (ii) the Warrant Agreement must be in writing and executed
     only by Agent and XPLOR.

            (d) Conflicts.  Any conflict or ambiguity between the terms and

      14.9     Multiple Counterparts.  Any Loan Document may be executed in a
               ---------------------                                         
number of identical counterparts with the same effect as if all signatories had
signed the same document.  All counterparts must be construed together to
constitute one and the same instrument.

      14.10    Parties.
               ------- 

               (a)  Parties Bound. Each Loan Document binds and inures to the
                    -------------  
     parties to it, any intended beneficiary of it, and each of their respective
     successors and permitted assigns. No Company may assign or transfer any
     Rights or obligations under any Loan Document without first obtaining all
     Lenders' consent, and any purported assignment or transfer without Lenders'
     consent is void. No Lender may transfer, pledge, assign, sell any
     participation in, or otherwise encumber its portion of the Obligation
     except as permitted by CLAUSES (B) or (C) below.

               (b)  Participations. Any Lender may (subject to the provisions of
                    --------------     
     this section, in accordance with applicable Law, in the ordinary course of
     its business, and at any time) sell to one or more Persons (each a
     "PARTICIPANT") participating interests in its portion of the Obligation.
     The selling Lender remains a "Lender" under the Loan Documents, the
     Participant does not become a "Lender" under the Loan Documents, and the
     selling Lender's obligations under the Loan Documents remain unchanged. The
     selling Lender remains solely responsible for the performance of its
     obligations and remains the holder of its share of the Principal Debt for
     all purposes under the Loan Documents. Borrower and Agent shall continue to
     deal solely and directly with the selling Lender in connection with that
     Lender's Rights and obligations under the Loan Documents, and each Lender
     must retain the sole right and responsibility to enforce due obligations of
     the Companies. Participants have no Rights under the Loan Documents except
     as provided below. Subject to the following, each Lender may obtain (on
     behalf of its Participants) the benefits of SECTION 3 with respect to all
     participations in its part of the Obligation outstanding from time to time
     so long as Borrower is not obligated to pay any amount in excess of the
     amount that would be due to that Lender under SECTION 3 calculated as
     though no participations have been made. No Lender may sell any
     participating interest under which the Participant has any Rights to
     approve any amendment, modification, or waiver of any Loan Document except
     as to matters in SECTION 14.8(B)(I) and (II).

               (c)  Assignments. Each Lender may make assignments to the Federal
                    -----------         
     Reserve Bank. Each Lender may also assign to one or more assignees (each an
     "ASSIGNEE") all or any part of its Rights and obligations under the Loan
     Documents so long as (i) the assignor Lender and Assignee execute and
     deliver to Agent and Borrower for their consent and acceptance (that may
     not be unreasonably withheld in any instance and is not required if the
     Assignee is an Affiliate of the assigning Lender) an assignment and
     assumption agreement in substantially the form of EXHIBIT F (an
     "ASSIGNMENT") and pay to Agent a processing fee of $2,500, (ii) the
     assignment is for an identical percentage of the assignor Lender's Rights
     and obligations under the Bridge Facility and the Revolving Facility, (iii)
     the assignment must be for a minimum total Commitment of $5,000,000 and the
     assigning Lender must retain a minimum total Commitment of $5,000,000, and
     (iv) the conditions for that assignment set forth in the applicable
     Assignment are satisfied. The Effective Date in each Assignment must
     (unless a shorter period is agreeable to Borrower and Agent) be at least
     five Business Days after it is executed and delivered by the assignor
     Lender and the Assignee to Agent and Borrower for acceptance. Once that
     Assignment is accepted by Agent and Borrower, and subject to all of the
     following occurring, then, on and after the Effective Date stated in it (i)
     the Assignee automatically becomes a party to this agreement and, to the
     extent provided in that Assignment, has the Rights and obligations of a
     Lender under the Loan Documents, (ii) the assignor Lender, to the extent
     provided in that Assignment, is released from its obligations

                                       53

     to fund Borrowings under this agreement and its reimbursement obligations
     under this agreement and, in the case of an Assignment covering all of the
     remaining portion of the assignor Lender's Rights and obligations under the
     Loan Documents, that Lender ceases to be a party to the Loan Documents,
     (iii) Borrower shall execute and deliver to the assignor Lender and the
     Assignee the appropriate Notes in accordance with this agreement following
     the transfer, (iv) upon delivery of the Notes under CLAUSE (III) preceding,
     the assignor Lender shall return to Borrower all Notes previously delivered
     to that Lender under this agreement, and (v) SCHEDULE 2 is automatically
     deemed to be amended to reflect the name, address, telecopy number, and
     Commitment of the Assignee and the remaining Commitment (if any) of the
     assignor Lender, and Agent shall prepare and circulate to Borrower and
     Lenders an amended SCHEDULE 2 reflecting those changes.

any other employee plan of the Company or any of its Subsidiaries, including the
plan of any acquired entity, or (b) made to any Company or Subsidiary employee
by the Company or any Subsidiary. An Award may provide for the granting or
issuance of additional, replacement or alternative Awards upon the occurrence of
specified events, including the exercise of the original Award. The occurrence
of a Change of Control shall result in acceleration of the vesting and
exercisability of and lapse of restrictions with respect to, all Awards.
Notwithstanding anything herein to the contrary, no Participant may be granted
Awards consisting of stock options or stock appreciation rights exercisable for
more than 25% of the shares of Common Stock originally authorized for Awards
under this Plan, subject to adjustment as provided in Paragraph 14. In the event
of an increase in the number of shares authorized under the Plan, the 25%
limitation will apply to the number of shares authorized.

     (i)   STOCK OPTION.  An Award may consist of a right to purchase a
specified number of shares of Common Stock at a price specified by the Committee
in the Award Agreement or otherwise. A stock option may be in the form of an
incentive stock option ("ISO") which, in addition to being subject to applicable
terms, conditions and limitations established by the Committee, complies with
Section 422 of the Code, or in the form of a Nonqualified Option.
Notwithstanding the foregoing, no ISO can be granted under the Plan more than
ten years following the Effective Date of the Plan.

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

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

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

     8.   PAYMENT OF AWARDS.

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

     (b)  DEFERRAL.  The Committee may, in its discretion, (i) permit selected
Participants to elect to defer payments of some or all types of Awards in
accordance with procedures established by the Committee or (ii) provide for the
deferral of an Award in an Award Agreement or otherwise. Any such deferral may
be in the form of installment payments or a future lump sum payment. Any
deferred payment, whether elected by the Participant or specified by the Award
Agreement or by the Committee, may be forfeited if and to the extent that the
Award Agreement so provides.

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

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

                                      -5-
<PAGE>
 
     9.   STOCK OPTION EXERCISE.  The price at which shares of Common Stock may
be purchased under a stock option shall be paid in full at the time of exercise
in cash or, if permitted by the Committee, by means of tendering Common Stock or
surrendering all or part of that or any other Award, including Restricted Stock,
valued at Fair Market Value on the date of exercise, or any combination thereof.
The Committee shall determine acceptable methods for tendering Common Stock or
Awards to exercise a stock option as it deems appropriate. If permitted by the
Committee, payment may be made by successive exercises by the Participant. The
Committee may provide for procedures to permit the exercise or purchase of
Awards by (a) loans from the Company or (b) use of the proceeds to be received
from the sale of Common Stock issuable pursuant to an Award. Unless otherwise
provided in the applicable Award Agreement, in the event shares of Restricted
Stock are tendered as consideration for the exercise of a stock option, a number
of the shares issued upon the exercise of the stock option, equal to the number
of shares of Restricted Stock used as consideration therefor, shall be subject
to the same restrictions as the Restricted Stock so submitted as well as any
additional restrictions that may be imposed by the Committee.

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

     11.  AMENDMENT, MODIFICATION, SUSPENSION OR TERMINATION.  The Board
may amend, modify, suspend or terminate this Plan for the purpose of meeting or
addressing any changes in legal requirements or for any other purpose permitted
by law except that (a) no amendment or alteration that would impair the rights
of any Participant under any Award previously granted to such Participant shall
be made without such Participant's consent and (b) no amendment or alteration
shall be effective prior to approval by the Company's shareholders to the extent
such approval is then required pursuant to Rule 16b-3 in order to preserve the
applicability of any exemption provided by such rule to any Award then
outstanding (unless the holder of such Award consents) or to the extent
shareholder approval is otherwise required by applicable legal requirements.

     12.  TERMINATION OF EMPLOYMENT.  Upon the termination of employment by a
Participant, any unexercised, deferred or unpaid Awards shall be treated as
provided in the specific Award Agreement evidencing the Award. Unless otherwise
specifically provided in the Award Agreement, each Award granted pursuant to
this Plan which is a stock option shall provide that if the Participant ceases
to be employed by the Company or its affiliates for any reason whatsoever, the
option shall immediately terminate to the extent the option is not vested (or
does

                                      -6-
<PAGE>
 
not become vested as a result of such termination of employment) on the date the
Participant terminates employment.

     13.  ASSIGNABILITY.  Except as otherwise provided herein, no Award granted
under this Plan shall be sold, transferred, pledged, assigned or otherwise
alienated or hypothecated by a Participant other than by will or the laws of
descent and distribution, and during the lifetime of a Participant, any Award
shall be exercisable only by him, or, in the case of a Participant who is
mentally incapacitated, the Award shall be exercisable by his guardian or legal
representative. The Committee may prescribe and include in applicable Award
Agreements other restrictions on transfer. Any attempted assignment or transfer
in violation of this Paragraph 13 shall be null and void. Upon the Participant's
death, the personal representative or other person entitled to succeed to the
rights of the Participant (the 'Successor Participant') may exercise such
rights. A Successor Participant must furnish proof satisfactory to the Company
of his or her right to exercise the Award under the Participant's will or under
the applicable laws of descent and distribution.

     Subject to approval by the Committee in its sole discretion, all or a
portion of the Awards granted to a Participant under the Plan which are not
intended to be ISOs may be transferable by the Participant, to the extent and
only to the extent specified in such approval, to (i) the spouse, parent,
brother, sister, children or grandchildren of the Participant ('Immediate Family
Members'), (ii) a trust or trusts for the exclusive benefit of such Immediate
Family Members ('Immediate Family Member Trusts'), or (iii) a partnership or
partnerships in which such Immediate Family Members have at least 99% of the
equity, profit and loss interests ('Immediate Family Member Partnerships');
provided that the Award Agreement pursuant to which such Awards are granted (or
an amendment thereto) must expressly provide for transferability in a manner
consistent with this Section. Subsequent transfers of transferred Awards shall
be prohibited except by will or the laws of descent and distribution, unless
such transfers are made to the original Participant or a person to whom the
original Participant could have made a transfer in the manner described herein.
No transfer shall be effective unless and until written notice of such transfer
is provided to the Committee, in the form and manner prescribed by the
Committee. Following transfer, any such Awards shall continue to be subject to
the same terms and conditions as were applicable immediately prior to transfer,
and, except as otherwise provided herein, the term 'Participant' shall be deemed
to refer to the transferee. The events of termination of service in Paragraph 12
shall continue to be applied with respect to the original Participant, following
which the Awards shall be exercisable by the transferee only to the extent and
for the periods specified in this Plan and the Award Agreement.

     14.  ADJUSTMENTS.

     (a)  The existence of outstanding Awards shall not affect in any manner
the right or power of the Company or its shareholders to make or authorize any
or all adjustments, recapitalizations, reorganizations or other changes in the
capital stock of the Company or its business or any merger or consolidation of
the Company, or any issue of bonds, debentures, preferred or prior preference
stock (whether or not such issue is prior to, on a parity with or junior to the
Common Stock) or the dissolution or liquidation of the Company, or any sale or

                                      -7-
<PAGE>
 
transfer of all or any part of its assets or business, or any other corporate
act or proceeding of any kind, whether or not of a character similar to that of
the acts or proceedings enumerated above.

     (b)  In the event of any subdivision or consolidation of outstanding shares
of Common Stock or declaration of a dividend payable in shares of Common Stock
or capital reorganization or reclassification or other transaction involving an
increase or reduction in the number of outstanding shares of Common Stock, the
Committee may adjust proportionally (i) the number of shares of Common Stock
reserved under this Plan and covered by outstanding Awards denominated in Common
Stock or units of Common Stock; (ii) the exercise or other price in respect of
such Awards; and (iii) the appropriate Fair Market Value and other price
determinations for such Awards. In the event of any consolidation or merger of
the Company with another corporation or entity or the adoption by the Company of
a plan of exchange affecting the Common Stock or any distribution to holders of
Common Stock of securities or property (other than normal cash dividends or
dividends payable in Common Stock), the Committee shall make such adjustments or
other provisions as it may deem equitable, including adjustments to avoid
fractional shares, to give proper effect to such event. In the event of a
corporate merger, consolidation, acquisition of property or stock, separation,
reorganization or liquidation, the Committee shall be authorized, in its
discretion, (i) to issue or assume stock options, regardless of whether in a
transaction to which Section 424(a) of the Code applies, by means of
substitution of new options for previously issued options or an assumption of
previously issued options, (ii) to make provision, prior to the transaction, for
the acceleration of the vesting and exercisability of, or lapse of restrictions
with respect to, Awards (to the extent not otherwise provided under paragraph 7)
and the termination of options that remain unexercised at the time of such
transaction or (iii) to provide for the acceleration of the vesting and
exercisability of the options and SARs and the cancellation thereof (to the
extent not otherwise provided under paragraph 7) in exchange for such payment as
shall be mutually agreeable to the Participant and the Committee.

     15.  RESTRICTIONS.  No Common Stock or other form of payment shall be
issued with respect to any Award unless the Company shall be satisfied based on
the advice of its counsel that such issuance will be in compliance with
applicable federal and state securities laws.  It is the intent of the Company
that this Plan comply with Rule 16b-3 with respect to persons subject to Section
16 of the Exchange Act unless otherwise provided herein or in an Award
Agreement, that any ambiguities or inconsistencies in the construction of this
Plan be interpreted to give effect to such intention and that, if any provision
of this Plan is found not to be in compliance with Rule 16b-3, such provision
shall be null and void to the extent required to permit this Plan to comply with
Rule 16b-3.  Certificates evidencing shares of Common Stock delivered under this
Plan may be subject to such stop transfer orders and other restrictions as the
Committee may deem advisable under the rules, regulations and other requirements
of the Securities and Exchange Commission, any securities exchange or
transaction reporting system upon which the Common Stock is then listed and any
applicable federal and state securities law.  The Committee may cause a legend
or legends to be placed upon any such certificates to make appropriate reference
to such restrictions.

                                      -8-
<PAGE>
 
     16.  UNFUNDED PLAN.  Insofar as it provides for Awards of cash, Common
Stock or rights thereto, this Plan shall be unfunded. Although bookkeeping
accounts may be established with respect to Participants who are entitled to
cash, Common Stock or rights thereto under this Plan, any such accounts shall be
used merely as a bookkeeping convenience. The Company shall not be required to
segregate any assets that may at any time be represented by cash, Common Stock
or rights thereto, nor shall this Plan be construed as providing for such
segregation, nor shall the Company, the Board or the Committee be deemed to be a
trustee of any cash, Common Stock or rights thereto to be granted under this
Plan. Any liability or obligation of the Company to any Participant with respect
to a grant of cash, Common Stock or rights thereto under this Plan shall be
based solely upon any contractual obligations that may be created by this Plan
and any Award Agreement, and no such liability or obligation of the Company
shall be deemed to be secured by any pledge or other encumbrance on any property
of the Company. None of the Company, the Board or the Committee shall be
required to give any security or bond for the performance of any obligation that
may be created by this Plan.

     17.  PARACHUTE PAYMENT LIMITATION.  Notwithstanding any contrary provision
of the Plan, the Committee may provide in the Award Agreement for a limitation
on the acceleration of vesting and exercisability of unmatured Awards to the
extent necessary to avoid or mitigate the impact of the golden parachute excise
tax under Section 4999 of the Code on the Participant or may provide for a
supplemental payment to be made to the Participant as necessary to offset or
mitigate the impact of the golden parachute excise tax on the Participant. In
the event the Award Agreement does not contain any contrary provision regarding
the method of avoiding or mitigating the impact of the golden parachute excise
tax under Section 4999 of the Code on the Participant, then notwithstanding any
contrary provision of this Plan, the aggregate present value of all parachute
payments payable to or for the benefit of a Participant, whether payable
pursuant to this Plan or otherwise, shall be limited to three times the
Participant's base amount less one dollar and, to the extent necessary, the
exercisability of an unmatured Award shall be reduced in order that this
limitation not be exceeded. For purposes of this Section 17, the terms
"parachute payment," "base amount" and "present value" shall have the meanings
assigned thereto under Section 280G of the Code. It is the intention of this
Section 17 to avoid excise taxes on the Participant under Section 4999 of the
Code or the disallowance of a deduction to the Company pursuant to Section 280G
of the Code.

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

     19.  EFFECTIVE DATE OF PLAN.  This Plan shall be effective as of the date
(the "Effective Date") it is approved by the Board of Directors of the Company.
Notwithstanding the foregoing, the adoption of this Plan is expressly
conditioned upon the approval by written consent of the holders of a majority of
shares of outstanding shares of Common Stock on or before the first anniversary
of the Effective Date. If the shareholders of the Company should fail so to

                                      -9-
<PAGE>
 
approve this Plan prior to such date, this Plan shall terminate and cease to be
of any further force or effect and all grants of Awards hereunder shall be null
and void.

                                ---------------



          XPLOR Energy, Inc. (the "Company"), having established the XPLOR
Energy, Inc. Long-Term Incentive Plan, effective September 30, 1997 (the
"Plan"), and having reserved the right under Section 11 thereof to amend the
Plan, does hereby amend the Plan as follows:



          1.   Section 3 of the Plan is hereby amended in its entirety, to read
as follows:

     "3.  Eligibility.  All employees, independent contractors and consultants
of the Company and its Subsidiaries are eligible for Awards under this Plan;
provided, however that only an employee of the Company and its Subsidiaries will
be deemed eligible for an ISO under this Plan. The Committee shall select the
Participants in the Plan from time to time by the grant of Awards under the
Plan."



                              Attested to by the Secretary of XPLOR Energy, Inc.
                              as adopted by the Board of Directors and
                              Shareholders of XPLOR Energy, Inc. effective as of
                              the 30th day of September, 1997 (the "Effective
                              Date").

                             EMPLOYMENT AGREEMENT
                             --------------------
                                   (REVISED)

     This revised Agreement is entered into this 18th day of June, 1997, to be
effective on the date set forth below, by and between Araxas Energy Corporation,
an Oklahoma corporation ("Corporation"), and Steven W. Nance ("Employee").

                                  WITNESSETH:
                                  ---------- 

     WHEREAS, Corporation desires to employ Employee, and Employee desires to
accept such employment;

     WHEREAS, Corporation and Employee desire to agree to the specific term of
such employment set forth in this Agreement.

     NOW, THEREFORE, in consideration of the recitations stated above and the
mutual terms, covenants and conditions contained herein, Corporation and
Employee agree as follows:

          1.   EMPLOYMENT
               ----------

               1.1   Employment.  Corporation hereby employs Employee and
     Employee hereby accepts such employment, as President and Chief Executive
     Officer, subject to the supervision and direction of Corporation's Chairman
     and its Board of Directors. No later than June 30, 1997, W. E. Rowsey, III
     will nominate Employee to serve on the Board of Directors of Corporation
     (the "Board of Directors") as a full member thereof, and will vote in favor
     of such nomination. It is the intention of the parties that Employee will
     be elected to and will serve on the Board of Directors while serving
     hereunder as President and Chief Executive Officer. W. E. Rowsey, III and
     Employee agree to work together to identify and install mutually acceptable
     independent Directors as provided in Corporation's Bylaws. W. E. Rowsey,
     III has executed this Agreement in his individual capacity for the sole
     purpose of agreeing to the foregoing three sentences.

               1.2   Term of Employment.  The term of employment shall commence
     on January 22, 1997, or as soon thereafter as possible ("Effective Date"),
     and shall terminate on the third anniversary of the Effective Date, unless
     further extended as hereinbelow provided or sooner terminated as provided
     in Section 4 hereof. On the third anniversary of the Effective Date, and on
     each following annual anniversary thereafter, the term of Employee's
     employment shall be automatically extended on the terms and condition then
     in effect for one (1) additional year unless, at least ninety (90) days
     prior to any such anniversary date, either


                                      -1-
<PAGE>
 
     party shall have delivered to the other, written notice that the term
     hereof shall not be extended.

          2.   DUTIES
               ------

               2.1   Full-time Employment.  Unless otherwise authorized by
     Corporation, Employee shall devote substantially all of his business time,
     attention and skills to the performance of his duties as President and
     Chief Executive Officer of Corporation. During the term of this Agreement,
     Employee shall not render services for any other than Corporation unless
     otherwise authorized by Corporation. Provided that no conflict exists with
     Corporation or the performance by Employee of his duties hereunder, this
     provision is not intended to preclude personal oil and gas investments or
     other passive investments that will not require services on the part of
     Employee nor to preclude the performance of community services by Employee.

               2.2   Employer-Employee Relationship.  The relationship between
     Corporation and Employee is that of an employer and employee. Corporation
     shall have the right to instruct, control, review and, subject to the terms
     of this Agreement, modify the nature as requested by Corporation and scope
     of services, and manner in which Employee performs such services for
     Corporation.

          3.   COMPENSATION AND RELATED MATTERS.  Subject to the terms and
conditions hereof, Employee shall receive the following salary and other
benefits as full consideration for the services to be rendered hereunder:

               3.1   Regular Salary.  A salary shall be paid to Employee for all
     services rendered under this Agreement at the rate of $175,000 per year,
     payable in equal semi-monthly installments of $7,291.67 as nearly as
     practicable to the 15th and the last day of each month in arrears. In the
     event that, prior to January 1, 1998, Corporation becomes subject to the
     reporting requirements of the Securities Exchange Act of 1934, Employee's
     salary will be increased to a rate of $200,000 per year, payable in equal
     semi-monthly installments of $8,333.33 as nearly as practical to the 15th
     and the last day of each month in arrears. Effective January 1, 1998,
     Employee's salary will be increased to a rate of at least $225,000 per
     year, payable in equal semi-monthly installments as nearly as practical to
     the 15th and the last day of each month in arrears. If Employee is employed
     for less than the entire pay period, the salary shall be prorated in
     accordance with the number of days during such pay period in which he is
     employed. The salary shall be reviewed annually, and may be increased, but
     not decreased, from the salary then in effect or the salary prescribed by
     this Section 3.1, in Corporation's discretion, as determined by the
     Compensation Committee of the Board of Directors.

               3.2   Expenses.  The Employee shall be reimbursed for all
     reasonable and necessary business expenses incurred in the performance of
     service hereunder, and are


                                      -2-
<PAGE>
 
     accounted for in accordance with the policies and procedures established
     from time to time by Corporation.

               3.3   Vacation.  Employee shall be entitled to four (4) weeks
     paid vacation during each full 12-month period during the term hereof and
     such other vacation time and paid holidays, if any, as shall from time to
     time be determined by Corporation.

               3.4   Employee Benefit Plans.  Employee shall be included in all
     of the employee benefit plans existing now or in the future providing
     pension, thrift, profit sharing or similar benefits as are provided
     generally to officers of Corporation, subject to the terms and conditions
     of all such plans. In addition, Employee shall be eligible to participate
     in all executive compensation programs applicable to other officers of
     Corporation, subject to the terms and conditions of such programs;
     provided, however, that Employee shall not participate in any overriding
     royalty plan unless and only to the extent that it is made available to
     other officers after July 31, 1998.

               3.5   Insurance and Welfare Benefit Plans.  Corporation shall
     cover Employee under its group medical and hospitalization plan, shall
     provide Employee term life insurance coverage, and will cover Employee
     under other insurance and employee welfare benefit plans maintained for its
     officers generally.

               3.6   Stock Grant.  Employee shall receive a restricted grant of
     Corporation common stock in accordance with the terms set forth in Exhibit
     A. Corporation represents and warrants that there were 118,628.65 shares of
     common stock of Corporation outstanding on the Effective Date and no other
     class of common stock and no preferred stock was outstanding on the
     Effective Date. Corporation has approximately 30,000 shares of Common Stock
     subject to outstanding options, with an aggregate exercise price of
     $1,675,000. Employee waives and revokes any right to a restricted grant of
     common stock under the terms of the Employment Agreement dated January 21,
     1997.

               3.7   Stock Option Plan.  Employee shall receive an option to
     acquire Corporation common stock in accordance with the terms set forth in
     Exhibit B. Employee waives and revokes any right to an option award under
     the terms of the Employment Agreement dated January 21, 1997.

               3.8   Incentive Bonus.  Employee shall be eligible to receive up
     to one hundred percent (100%) of annual base salary as an annual bonus. The
     bonus for 1997 shall be fixed at $200,000 and shall be paid no later than
     the end of January, 1998; provided, however, that this bonus shall be
     payable only if, prior to January 1, 1998, Corporation has become subject
     to the reporting requirements of the Securities Exchange Act of 1934 and
     the outstanding liability to the Stratum Group, LP has been paid. Beginning
     in 1998, the bonus shall be based on attainment of performance goals to be
     established no later than the end of the first quarter of each calendar
     year, subject to approval of those performance goals by the

                                      -3-

     Board of Directors, which will provide for at least the following:  (i)
     financial targets, (ii) operating targets, and (iii) stock price targets.

     4.   TERMINATION OF AGREEMENT.  This Agreement will continue in effect
until the expiration of the term stated in Section 1 hereof unless sooner
terminated as set forth below.  If such termination occurs, Employee shall
continue to be subject to Section 5 hereof.

               4.1   Death of Employee.  If Employee shall terminate employment
     due to death during the term of this Agreement, this Agreement shall
     terminate and his spouse, if she is then surviving or if not, his legal
     representative, shall be entitled to receive (i) his compensation as
     provided in Section 3.1 through the end of the month in which death occurs
     and (ii) a pro rata share of incentive compensation under Section 3.8 based
     on the number of days in the year that elapsed prior to death and as if all
     performance goals had been met.

               4.2   Illness or Other Incapacity.  If during the term of this
     Agreement, Employee shall fail to perform his duties hereunder as a result
     of illness or other incapacity and such illness or incapacity shall
     continue for a period of more than three (3) months, Corporation shall have
     the right to terminate this Agreement and the employment hereunder as of
     date to be specified in a notice of termination, such date to be not less
     than thirty (30) days after the mailing by certified mail of such notice.
     If Employee's illness or incapacity shall have ended, and the Employee
     shall have assumed his duties hereunder, prior to the date specified in the
     notice of termination, he shall be entitled to resume his employment
     hereunder as if such notice had not been given. If such termination occurs,
     Employee shall continue to be bound by the covenants contained in Section 5
     hereof, but in all other regards, this Agreement shall terminate as of such
     termination date, and Corporation shall pay to Employee or his legal
     representative (i) the amount of any accrued but unpaid compensation under
     Section 3.1 hereof through termination of employment, (ii) a pro rata share
     of incentive compensation under Section 3.8 based on the number of days in
     the year that elapsed prior to such termination and as if all performance
     goals had been met, and (iii) such other benefits, if any, as may be
     determined by Corporation.

               4.3   Termination by Corporation for Cause.  Corporation may
     terminate this Agreement and the employment of Employee by service of
     written notice of termination to Employee specifying the circumstances and
     an effective date for such termination upon the earlier to occur of any of
     the following events: (i) Employee willfully misappropriates the property
     of Corporation or commits any other act of dishonesty which results in
     injury to Corporation or reasonably could result in injury to Corporation;
     (ii) Employee engages in personal misconduct which results in injury to
     Corporation, or could reasonably result in injury to Corporation unless
     Employee in good faith reasonably believed that his actions were in the
     best interest of Corporation; (iii) Employee is convicted of a felony; or
     (iv) the Board of Directors has determined in good faith that Employee has
     failed to diligently perform his duties hereunder as specified by
     Corporation and in a manner consistent with prudent business practice and
     such failure continues after Employee has been given at least


                                      -4-
<PAGE>
 
     ten (10) days' written notice of the failure.  In the event this Agreement
     is terminated for cause set forth in paragraphs (i) through (iv) above,
     Corporation will have no obligation to provide any further salary payments
     or other benefits hereunder to Employee, including, but not limited to
     salary and incentive compensation, for any period after the effective date
     of such termination.

               4.4   Termination by Corporation for Other than Cause.  In the
     event Corporation terminates Employee's employment for any reason other
     than under Section 4.3, Employee shall be entitled to a payment from
     Corporation in an amount equal to the Termination Payment (as hereinafter
     defined). For purposes of this Agreement, the term "Termination Payment"
     shall mean an amount equal to the sum of (i) all base salary that would
     have been paid to Employee pursuant to Section 3.1 during the balance of
     the term of employment provided for in Section 1.2 (but in no event less
     than 12 months of such base salary) (the "Salary Portion"), and (ii)
     subject to the execution by Employee of a waiver and release of all claims
     against Corporation, all incentive compensation that would have been paid
     to Employee pursuant to Section 3.8 (determined based on an annual
     incentive bonus of 100% of annual base salary and as if all performance
     goals had been met) during the balance of the term provided for in Section
     1.2 (but in no event less than one such annual incentive bonus) (the "Bonus
     Portion"). The Termination Payment shall be paid (i) with respect to the
     Bonus Portion, in a single lump sum cash payment within five (5) days after
     Employee has signed a release and any applicable revocation period has
     expired and (ii) with respect to the Salary Portion, in a single lump sum
     cash payment within five (5) days after such termination of employment.

               4.5   Termination Following Change of  Control.  In the event
     that a "Change of Control" (as hereinafter defined) occurs and following
     such Change of Control Employee's employment is terminated by Corporation
     for a reason other than as described in Section 4.3, or he voluntarily
     terminates employment due to a substantial diminishment in his job
     responsibilities or duties or a material breach by Corporation of any
     material provision of this Agreement or any other agreement with Employee
     which remains uncorrected for 10 days following written notice of such
     diminishment or breach by Employee to Corporation, then, in lieu of any
     payments pursuant to Sections 4.4 or 4.6 hereof, Employee shall be entitled
     to a Termination Payment under terms and conditions applicable pursuant to
     Section 4.4, provided that the reference therein to 12 months shall be
     deemed to be a reference to 24 months and the reference to one such annual
     incentive bonus shall be deemed to be a reference to two such annual
     incentive bonuses. A "Change of Control" shall mean (i) any sale by
     Corporation of substantially all of its assets or (ii) the resignation,
     removal or failure to re-elect W. E. Rowsey, III as a member of the Board
     of Directors for any reason other than disability or death, or (iii) the
     acquisition by any "person," including a "group" as determined in
     accordance with Section 13(d)(3) of the Securities Exchange Act of 1934, of
     beneficial ownership, directly or indirectly, of securities of Corporation
     representing 50% or more of the combined voting power of Corporation's then
     outstanding securities; provided, however, that no Change of Control shall
     be deemed

                                      -5-
<PAGE>
 
     to occur if beneficial ownership in Corporation's then outstanding
     securities is acquired pursuant to any reorganization of Corporation or
     recapitalization, spinoff or other transaction if, after giving effect to
     such transaction, however structured, at least 50% of the outstanding
     voting securities with the ultimate parent entity corporation are
     beneficially owned in the aggregate, directly or indirectly through one or
     more intermediaries, by the former shareholders of Corporation.

               4.6   Termination by Employee for Good Reason.  If Employee's
     employment hereunder shall be terminated by Employee due to a substantial
     diminishment in Employee's job responsibilities or duties or a material
     breach by Corporation of any material provision of this Agreement or any
     other agreement with Employee which remains uncorrected for 10 days
     following written notice of such diminishment or breach by Employee to
     Corporation, then Employee shall be entitled to a Termination Payment under
     terms and conditions applicable pursuant to Section 4.4.

               4.7   Voluntary Termination by Employee.  Notwithstanding any
     provision herein to the contrary, Employee shall have the right to
     terminate his employment under this Agreement at any time and for any
     reason whatsoever. If Employee's employment hereunder shall be terminated
     by Employee for any reason whatsoever other than the reasons specified in
     Sections 4.1, 4.2, 4.5 or 4.6, then, upon such termination, all
     compensation and all benefits to Employee hereunder shall terminate
     contemporaneously with the termination of such employment.

               4.8   No Duty to Mitigate Losses.  Employee shall have no duty to
     find new employment following the termination of his employment under
     circumstances which required Corporation to pay any amount to Employee
     pursuant to this Section 4. Any salary or remuneration received by Employee
     from a third party for the providing of personal services (whether by
     employment or by functioning as an independent contractor) following the
     termination of his employment under circumstances pursuant to which
     Sections 4.2, 4.4, 4.5, 4.6 or 6.7 apply shall not reduce Corporation's
     obligation to make a payment to Employee (or the amount of such payment)
     pursuant to the terms of any such Section.

               4.9   Liquidated Damages.  In light of the difficulties in
     estimating the damages for an early termination of this Agreement,
     Corporation and employee hereby agree that the payments, if any, to be
     received by Employee pursuant to Sections 4.1, 4.2, 4.4, 4.5, 4.6 or 6.7
     shall be received by Employee as liquidated damages.

               4.10  Incentive and Deferred Compensation.  This Agreement
     governs the rights and obligations of Employee and Corporation with respect
     to Employee's base salary, incentive compensation pursuant to Section 3.8
     and certain perquisites of employment. Employee's rights and obligations
     both during the term of his employment and thereafter with respect to stock
     options, restricted stock, incentive and deferred compensation (other than
     incentive compensation payable pursuant to Section 3.8), life insurance
     policies insuring

                                      -6-
<PAGE>
 
     the life of Employee, and other benefits under the plans and programs
     maintained by Corporation shall be governed by the separate agreements,
     plans and other documents and instruments governing such matters
     (including, without limitation, the Restricted Stock Agreement and Stock
     Option Agreement referenced in Exhibits A and B hereof).

          5.   AGREEMENT RESTRICTING TRADE SECRETS AND COMPETITION
 
               5.1   Confidential Information and Trade Secrets.  Employee
     acknowledges that he will have access to and that there will be disclosed
     to him during the course of this employment, information of a proprietary
     nature owned by Corporation, which is of a confidential nature and all of
     which have great value to Corporation and which is a substantial basis and
     foundation upon which Corporation's business is predicated.  Employee
     acknowledges that except for his employment and the duties assigned to him
     which he will be fulfilling, that he would not otherwise have access to the
     foregoing information.  Employee agrees that any and all confidential
     knowledge or information which may be obtained by him in the course of his
     employment will be held inviolate by him and that he will conceal the same
     from any and all other persons, including, but not limited to, competitors
     of Corporation, and that he will not impart any such knowledge acquired by
     him as an employee of Corporation to anyone whomsoever either during this
     employment or after his employment by Corporation has terminated, except to
     the extent (i) such disclosure is required by law, (ii) such information is
     otherwise made public by Corporation (other than by Employee in violation
     hereof), or (iii) such disclosure is made in the normal course of business
     and is consistent with Corporation's interests.

               Employee agrees that upon termination of his employment hereunder
     he will immediately surrender and turn over to Corporation all books,
     records, forms data, electric logs, geological maps, scout cards, seismic
     tapes and all papers and writing relating to the business of Corporation
     and other information which reflects or reveals Corporation's confidential
     or trade secret information protected by this Section, and all other
     property belonging to Corporation, it being understood and agreed that the
     same are the sole property of Corporation and that Employee will not make
     any copies thereof; provided, however, the parties agree that Employee's
     personnel files and any logs, records, and maps which were Employee's
     property prior to the Effective Date shall remain Employee's property.  For
     purposes of this Section 5, the term "Corporation" shall include
     Corporation as herein defined and any of its subsidiaries, affiliates or
     parent organizations.

               5.2   Noncompetition Agreement.  Except as provided in Section
     2.1, for so long as this Agreement is in effect and for a period of six (6)
     months after termination of this Agreement, Employee will not, without
     Corporation's written permission, directly or indirectly, own, manage,
     operate, control, be employed by, participate in or be connected in any
     manner with the ownership, management, operation, or control of any
     business which is in direct competition with Corporation, specifically with
     respect to the geologic prospects


                                      -7-
<PAGE>
 
     or any planned or completed acquisitions (of stock, equity or assets) in or
     through which Corporation does explore, develop or produce oil and gas or
     has current plans to explore, develop or produce oil and gas.  For so long
     as this Agreement is in effect and for a period of six (6) months after
     termination of this Agreement, Employee shall refrain from contacting or
     encouraging any third party to contact any individual who is employed by
     Corporation or its affiliates for the purpose of recruiting or placing that
     individual with any other employer.

               5.3   Injunctive Relief.  Employee specifically acknowledges and
     agrees that the remedy at law for any breach of the provisions of Sections
     5.1 or 5.2 will be inadequate and that Corporation shall be entitled to
     temporary and permanent injunctive relief without the necessity of proving
     actual damage.

               5.4   Reformation.  In the event that the provisions of this
     Section 5 should ever be deemed to exceed the time or geographic
     limitations permitted by applicable law, then such provisions shall be
     deemed reformed to the maximum time or geographic limitations permitted by
     applicable law.

          6.   GENERAL

               6.1   Indemnity and Directors' & Officers' Liability Insurance
     Coverage.  Corporation agrees to indemnify and defend Employee, at
     Corporation's sole expense, in any matters arising from Employee's
     performance of his duties as an employee, officer or director of
     Corporation or any of Corporation's subsidiaries or affiliates to the
     fullest extent permitted by law.  The Corporation will take reasonable
     steps to obtain Directors' and Officers' liability insurance prior to
     becoming subject to the reporting requirements of the Securities Exchange
     Act of 1934.

               6.2   Headings.  Section headings are included solely for
     convenience and should not be used in the interpretation of this Agreement.

               6.3   Severability.  In the event any one or more of the
     provisions contained in the Agreement shall, for any reason, be held to be
     invalid, illegal or unenforceable in any respect, such invalidity,
     illegality or unenforceability shall not effect any other provisions of
     this Agreement, and this Agreement shall be construed in all respects as if
     such invalid or unenforceable provisions were omitted.

               6.4   Notices.  Any notice, demand and all other communications
     required or permitted to be given under this Agreement shall be in writing
     and shall have been deemed duly given when delivered or (unless otherwise
     specified herein) three (3) business days after mailed by United States
     registered mail, return receipt requested, postage prepaid, to the address
     set forth on the signature page hereof, or to such other address as any
     part may 


                                      -8-
<PAGE>
 
     have furnished to the other in writing in accordance herewith, except that
     notices of change of address shall be effective only upon receipt.

               6.5   Waiver of Breach; Expenses.  The waiver by Employee or
     Corporation of a breach of any provision of this Agreement shall not
     operate or be construed as a waiver of any subsequent breach.  In any
     action brought by any party hereto, the prevailing party shall be entitled
     to collect such party's reasonable attorney's fees, court costs and
     expenses in such action.

               6.6   Binding Effect; Assignment.  The respective rights and
     obligations of Corporation and Employee under the Agreement shall inure to
     the benefit of and shall be binding upon Corporation and the respective
     successors and assigns of Corporation.  This Agreement shall not be
     assignable by Employee.  As used herein, the term "successors and assigns"
     shall include any corporation or corporations which acquire all or
     substantially all of the assets and businesses of Corporation whether by
     purchase, merger, consolidation or otherwise.  The parties hereto presently
     contemplate that Corporation will enter into certain transactions resulting
     in a reorganization of Corporation and in connection therewith this
     Agreement shall automatically be assigned to the parent of Corporation and
     all references herein to Corporation shall thereafter be deemed to be
     references to such parent entity.

               6.7   Certain Additional Payments by Company.  Notwithstanding
     anything to the contrary in this Agreement, in the event that any payment
     or distribution by Corporation to or for the benefit of Employee, whether
     paid or payable or distributed or distributable pursuant to the terms of
     this Agreement or otherwise (a "Payment"), would be subject to the excise
     tax imposed by Section 4999 of the Internal Revenue Code of 1986, as
     amended, or any interest or penalties with respect to such excise tax (such
     excise tax, together with any such interest or penalties, are hereinafter
     collectively referred to as the "Excise Tax"), Corporation shall pay to
     Employee an additional payment (a "Gross-up Payment") in an amount such
     that after payment by employee of all taxes (including any interest or
     penalties imposed with respect to such taxes), including any Excise Tax
     imposed on any Gross-up Payment, Employee retains an amount of the Gross-up
     Payment equal to the Excise Tax imposed upon the Payments. Corporation and
     Employee shall make an initial determination as to whether a Gross-up
     Payment is required and the amount of any such Gross-up Payment. Employee
     shall notify Corporation in writing of any claim by the Internal Revenue
     Service which, if successful, would require Corporation to make a Gross-up
     Payment (or a Gross-up Payment in excess of that, if any, initially
     determined by Corporation and Employee) within ten days of the receipt of
     such claim. Corporation shall notify Employee in writing at least ten days
     prior to the due date of any response required with respect to such claim
     if it plans to contest the claim. If Corporation decides to contest such
     claim, Employee shall cooperate fully with Corporation in such action;
     provided, however, Corporation shall bear and pay directly or indirectly
     all costs and expenses (including additional interest and penalties)
     incurred in connection with such action and shall indemnify and hold
     Employee harmless, on an after-tax basis, for any Excise Tax or income


                                      -9-
<PAGE>
 
     tax, including interest and penalties with respect thereto, imposed as a
     result of Corporation's action. If, as a result of Corporation's action
     with respect to a claim, Employee receives a refund of any amount paid by
     Corporation with respect to such claim, Employee shall promptly pay such
     refund to Corporation. If Corporation fails to timely notify Employee
     whether it will contest such claim or Corporation determines not to contest
     such claim, then Corporation shall immediately pay to Employee the portion
     of such claim, if any, which it has not previously paid to Employee.

               6.8   Entire Agreement Counterparts.  Except as provided in (i)
     the benefits, plans, and programs referenced in Sections 3.4 and 3.5 hereof
     and (ii) any signed written agreements contemporaneously or hereafter
     executed by Corporation and Employee (including, but not limited to, the
     Restricted Stock Agreement and the Stock Option Agreement referenced in
     Exhibits A and B hereof), this Agreement contains the entire agreement of
     the parties hereto, notwithstanding any oral representation of the parties
     to the contrary. This Agreement supersedes as of the Effective Date all
     agreements, oral or in writing, and other arrangements between the parties
     with respect to all matters related to the subject matter hereof. This
     Agreement may be executed in multiple counterparts, all of which shall
     constitute one Agreement, but both parties must execute and deliver one
     signed counterpart before this Agreement is effective.

               6.9   Applicable Law.  The execution, performance and enforcement
     of this Agreement shall be governed by and construed in accordance with the
     internal laws of the State of Texas without giving effect to its conflict
     of laws provisions.

               6.10  Survival.  All covenants, representations and warranties of
     the parties hereto will survive the termination of this Agreement.

                       EXHIBIT A TO EMPLOYMENT AGREEMENT

                    TERMS OF RESTRICTED COMMON STOCK AWARD
                    --------------------------------------



1.   FORM OF AWARD.

     As soon as practicable after June 18, 1997, Employee shall receive 1,456
shares of common stock of Corporation (the "Awarded Shares").

2.   VESTING OF AWARD.

     Subject to Employee's continued service with Corporation, he shall become
vested in one-third of the Awarded Shares on January 21, 1998, in an additional
installment of one-third of the Awarded Shares on January 21, 1999, and in the
remaining one-third of the Awarded Shares on January 21, 2000.  All of the
Awarded Shares shall become vested immediately upon the occurrence of a Change
of Control.  In the event of Employee's termination of employment for any reason
prior to January 21, 2000, any Awarded Shares that have not previously become
vested shall be forfeited to Corporation.

3.   PAYMENT BY EMPLOYEE.

     Employee agrees to pay Corporation the $.01 per share par value of the
Awarded Shares contemporaneously with the transfer of the Awarded Shares.
Employee represents and warrants that he is an "accredited investor" as such
term is defined in Rule 501 of Regulation D under the Securities Act of 1933, as
amended.

4.   REPURCHASE RIGHTS.

     In the event that Employee terminates employment prior to the date
Corporation has become subject to the reporting requirements of  the Securities
Exchange Act of 1934, then Corporation shall have the obligation to repurchase
all of the Awarded Shares that have become vested, or any lesser number
designated by Employee,  if the Employee gives a written sale notice to
Corporation within 90 days of termination.  Corporation shall purchase the
vested Awarded Shares to be sold by Employee for their fair market value,
determined as of the termination date in good faith by the Board of Directors
without regard to any minority discount or limitations on liquidity.  In the
event that Employee is not satisfied with the fair market value determination of
the Board of Directors, Employee may require such fair market value to be
determined by an independent appraiser mutually acceptable to Employee and
Corporation, and Employee and Corporation agree to be bound by the determination
of such appraiser.  Employee agrees to pay one-half of the appraiser's fees and
expenses, but not to exceed $10,000, and Corporation shall pay the balance of
the appraiser's fees and expenses.  If Employee exercises his right to require
Corporation to repurchase his vested Awarded Shares, Corporation and Employee
agree that the repurchase and payment for the shares 


                                      -1-
<PAGE>
 
will be made in a single lump-sum cash payment and will occur within 30 days
after receipt by Corporation of notice of exercise, or, if later, within 30 days
after a fair market value determination is made by an independent appraiser. In
the event Employee does not elect to require Corporation to repurchase his
vested Awarded Shares, Corporation shall have a right of first refusal with
respect to any third-party sale of the vested Awarded Shares by Employee at the
price offered by the third party, and a right to repurchase the vested Awarded
Shares at their fair market value (established in the same manner as described
above) in the event of an involuntary transfer by Employee or gift or other
below-market transfer of the shares. Employee will have rights to transfer the
vested Awarded Shares to immediate family members or trusts and partnerships
benefitting such immediate family members provided such rights of first refusal
will continue to apply to the transferred Awarded Shares. Employee's right to
require Corporation to repurchase vested Awarded Shares and Corporation's right
of first refusal and repurchase shall terminate in the event Corporation becomes
subject to the reporting requirements of the Securities Exchange Act of 1934.

5.   REGISTRATION RIGHTS.

     Promptly after Corporation has become subject to the reporting requirements
of the Securities Exchange Act of 1934, Corporation shall file with the
Securities and Exchange Commission a registration statement on Form S-8 (or any
successor form) and shall include the Awarded Shares in that registration
statement, or shall take other appropriate steps as may be necessary to allow
Employee to resell the vested Awarded Shares in compliance with applicable
federal and state laws after transfer restrictions lapse.

6.   TRANSFER RESTRICTIONS.

     The nonvested Awarded Shares shall be subject to restrictions on transfers
to third parties, but Employee will have the right to participate, on the same
terms as other shareholders, in any sale of common stock that would constitute a
Change of Control.  In addition, Employee will enter into any reasonable lock-up
provision that is requested by underwriters pursuant to any public offering of
the common stock of Corporation and that is similar to that given by other
officers of Corporation restricting the transfer of common stock.

7.   TAXES.

     Corporation agrees to loan Employee up to, but not in excess of, $100,000
to enable Employee to satisfy his demonstrated income tax obligation arising as
a result of the grant of, or lapse of restrictions on, the Awarded Shares.  The
loan shall be evidenced by a Promissory Note executed by Employee with a three-
year term, with interest payable quarterly at Corporation's borrowing rate from
its principal lender as in effect on the date of the Promissory Note.  The
Promissory Note shall be secured by a number of Awarded Shares having a value
equal to the amount of the loan or, if greater, such value as will satisfy any
applicable margin restrictions or other legal requirements, and shall be fully
recourse against Employee.  The Promissory Note shall be payable in full upon
termination of employment by Employee for any reason.  Corporation shall be


                                      -2-
<PAGE>
 
entitled to withhold from the loan proceeds the amount of income tax withholding
applicable with respect to the Awarded Shares.  In the event Employee does not
borrow from Corporation an amount sufficient to satisfy Corporation's income tax
withholding obligation, Employee agrees to make a cash payment to Corporation in
an amount equal to the balance of that income tax withholding obligation.

8.   RESTRICTED STOCK AGREEMENT.

     The parties agree to use their best efforts to more fully document the
terms described in this Exhibit A on or before June 30, 1997, (and agree in any
event to more fully document the terms prior to any merger of the Corporation
with another entity) in a form of a Restricted Stock Agreement, which will
contain terms permitting Corporation to retain custody of the Awarded Shares,
together with a stock power signed in blank by Employee, while the Awarded
Shares remain subject to forfeiture.  In addition, the Restricted Stock
Agreement shall be, to the extent not inconsistent with the terms set forth in
this Exhibit A, subject to the terms and conditions of a Long-Term Incentive
Plan intended to be implemented by Corporation and pursuant to which restricted
awards of common stock will be authorized.  The parties presently contemplate
that Corporation will enter into certain transactions resulting in a
reorganization of Corporation and in connection therewith  references to
Corporation herein shall become references to the parent entity where
appropriate.

9.   TERMS.

     Terms used in this Exhibit A but not defined herein have the same meaning
as the terms set forth in the Employment Agreement dated June 18, 1997 between
Araxas Energy Corporation and Steven W. Nance.

                       EXHIBIT B TO EMPLOYMENT AGREEMENT

                          TERMS OF STOCK OPTION AWARD
                          ---------------------------



1.   OPTION AWARD.

     Employee is hereby awarded, effective as of June 18, 1997, an option to
acquire 5,590 shares of Corporation common stock (the "Option Shares").  The per
share exercise price of the Option Shares shall be $250.00.  To the extent
consistent with the limitations of Section 422 of the Internal Revenue Code of
1986, as amended (the "Code"), this option shall be an incentive stock option,
and the remainder of  this option shall be a nonqualified option within the
meaning of Section 83 of the Code.

2.   EXERCISABILITY OF OPTION.

     One-third (1/3) of the Option Shares shall become exercisable on January
21, 1998, one-third (1/3) on January 21, 1999 and one-third (1/3) on January 21,
2000.

     In the event of a Change of Control, all of the Option Shares shall be
fully exercisable and the Vested Portion (as hereinafter defined) of Option
Shares shall thereafter mean all outstanding Option Shares.

     The Option Shares that become exercisable under the terms set forth above
will remain exercisable until termination of the option.

3.   TERMINATION OF EMPLOYMENT.

     In the event that Employee terminates employment due to an "Approved
Event," then Employee shall have the right to exercise the "Vested Portion" of
any Option Shares (determined as of the date of termination) during the period
ending ninety (90) days after termination of employment (or one year in  the
case of termination due to death or disability under Sections 4.1 or 4.2 of the
Agreement) and thereafter the option hereby granted shall terminate and be of no
force and effect with respect to any Option Shares not previously purchased by
Employee.  In the event Employee terminates employment for any reason other than
an "Approved Event," then the option hereby granted shall terminate and be of no
force and effect with respect to any Option Shares not previously purchased by
Employee upon the date of termination of employment.  An "Approved Event" shall
mean any termination of employment governed by Sections 4.1, 4.2, 4.4, 4.5 or
4.6 of the Agreement.

     With respect to Option Shares, the "Vested Portion" of Option Shares shall
mean  the number of Option Shares multiplied by a fraction (not to exceed 1.0),
the numerator of which is the number of days elapsed from the Effective Date to
the date of termination of employment, and the denominator of which is 947.


                                      -1-
<PAGE>
 
4.   TERM OF OPTION.

     The Option Term shall be the period ending on the tenth anniversary of the
Effective Date.  The option to acquire the Option Shares shall terminate and be
of no force and effect with respect to any Option Shares not previously
purchased by Employee upon the expiration of the Option Term.

5.   ADJUSTMENTS.

     The number of Option Shares and the exercise price for the Option Shares
shall be proportionally adjusted in the event of any subdivision or
consolidation of outstanding shares of Common Stock or declaration of a dividend
payable in shares of Common Stock or capital reorganization or reclassification
or other transaction involving an increase or reduction in the number of shares
of outstanding shares of Common Stock, unless Corporation has received cash or
property or labor or services in exchange therefor or is issuing securities
pursuant to rights or options outstanding as of the Effective Date.  The parties
presently contemplate that Corporation will enter into certain transactions
resulting in a reorganization of Corporation and in connection therewith this
option shall become an option to buy a number of shares of the parent of
Corporation proportional to the number of shares of each class of stock or other
securities of the parent corporation distributed to holders of common stock of
Corporation with respect to such shares, and references to Corporation herein
shall become references to the parent entity where appropriate.

6.   REGISTRATION RIGHTS.

     Promptly after Corporation has become subject to the reporting requirements
of the Securities Exchange Act of 1934, Corporation shall file with the
Securities and Exchange Commission a registration statement on Form S-8 (or any
successor form) and shall include the Option Shares in that registration
statement, or shall take other appropriate steps as may be necessary to allow
Employee to resell the Option Shares purchased in compliance with applicable
federal and state laws.

7.   REPURCHASE RIGHTS.

     In the event Employee terminates employment, Employee and Corporation shall
have the same rights and obligations with respect to the purchase and sale of
any Option Shares acquired by Employee due to exercise of the option under the
same terms and conditions as are applicable to restricted common stock acquired
by Employee pursuant to Exhibit A to the Agreement.

8.   STOCK OPTION AGREEMENT.

     The parties agree to use their best efforts to more fully document the
terms described in this Exhibit B by June 30, 1997 (and agree in any event to
more fully document the terms prior to any merger of the Corporation with
another entity) in a form of Stock Option Agreement, which will contain
customary terms regarding the procedure for exercise of the option. In addition,
the Stock Option Agreement shall be, to the extent not inconsistent with the
terms set forth in this Exhibit B,

                                      -2-
<PAGE>
 
subject to the terms and conditions of a Long-Term Incentive Plan intended to be
implemented by Corporation and pursuant to which stock option awards will be
authorized.

9.   TERMS.

     Terms used in this Exhibit B but not defined herein have the same meaning
as the terms set forth in the Employment Agreement dated June 18, 1997 between
Araxas Energy Corporation and Steven W. Nance.

                                                                   EXHIBIT 10.19

                             EMPLOYMENT AGREEMENT


     This Employment Agreement (the "Agreement") is entered into this 24th day
of September, 1997, to be effective on the date set forth below, by and between
XPLOR Energy, Inc., a Delaware corporation ("Corporation"), and R. A. Krenzke
("Employee").

                                  WITNESSETH:

     WHEREAS, Corporation desires to employ Employee, and Employee desires to
accept such employment;

     WHEREAS, Corporation and Employee desire to agree to the specific terms of
such employment set forth in this Agreement.

     NOW, THEREFORE, in consideration of the recitations stated above and the
mutual terms, covenants and conditions contained herein, Corporation and
Employee agree as follows:

     1.  EMPLOYMENT

         1.1 Employment. Corporation hereby employs Employee and Employee hereby
accepts such employment, as Executive Vice President and Chief Operating
Officer, subject to the supervision and direction of Corporation's President,
other Officers of the Corporation as applicable and its Board of Directors.

         1.2 Term of Employment.  The term of employment provided for in this
Agreement shall commence on September 24, 1997("Effective Date"), shall
remain in full force and effect for a period of three years thereafter and shall
terminate on the third anniversary of the Effective Date, unless terminated
sooner as provided in Section 4 hereof.  Beginning on the second anniversary of
the Effective Date, and on the last day of each succeeding month following the
second anniversary ("Monthly Renewal Date"), the term of Employee's employment
shall be automatically extended on the terms and condition then in effect for
one (1) additional month such that there shall always be at least one (1) year
remaining on the term of this agreement at all times, unless, at least fifteen
(15) days prior to the second anniversary of the Effective Date or any such
Monthly Renewal Date, either party shall have delivered to the other, written
notice that the term hereof shall not be extended.

     2.  DUTIES

         2.1 Full-time Employment. Unless otherwise authorized by Corporation,
Employee shall devote substantially all of his business time, attention and
skills to the performance of his duties as Executive Vice President and Chief
Operating Officer of Corporation; provided, however, that upon the approval of
Corporation, Employee may serve as a director of other corporations or entities
that engage in other activities to the extent that they do

                                      -1-
<PAGE>
 
not inhibit the performance of Employee's duties hereunder, or conflict with the
business of the Corporation, its subsidiaries, or affiliates. During the term of
this Agreement, Employee shall not render services for any other person or
entity than Corporation unless otherwise authorized by Corporation. The
voluntary performance by Employee of any duties assigned to him which are not of
the type provided for herein shall not constitute a waiver of his rights
hereunder or an abrogation, abandonment or termination by him of this Agreement.

     Employee shall not be restricted from engaging in a business or from
investing his assets in a manner which is non-competitive with Corporation and
its affiliates or subsidiaries and which will not require any significant
services on his part in the operation of the affairs of the companies in which
such investments are made or from engaging in charitable or voluntary activities
to the extent that the total amount of time expended on such business,
investing, charitable or voluntary activities is reasonable, is consistent with
Employee's duties hereunder, and does not conflict with Employee's ability or
time necessary to perform his duties hereunder.

     2.2  Employer-Employee Relationship.  The relationship between Corporation
and Employee is that of an employer and employee.  Corporation shall have the
right to instruct, control, review and, subject to the terms of this Agreement,
modify the nature as requested by Corporation and scope of services, and manner
in which Employee performs such services for Corporation.

 3.  COMPENSATION AND RELATED MATTERS.  Subject to the terms and conditions
hereof, Employee shall receive the following salary and other benefits as full
consideration for the services to be rendered hereunder.

     3.1  Regular Salary.  A salary shall be paid to Employee for all services
rendered under this Agreement at the annual rate of $165,000 per year, payable
in accordance with the general payroll practices of the Corporation in effect
from time to time. Employee's salary shall be reviewed annually, and may be
increased, but not decreased, from the salary then in effect or the salary
prescribed by this Section 3.1, in Corporation's discretion, as determined by
the Compensation Committee of the Board of Directors.

     3.2  Expenses.  The Employee shall be reimbursed for all reasonable and
necessary business expenses incurred in the performance of service hereunder,
and accounted for in accordance with the policies and procedures established
from time to time by Corporation.  In addition, employee shall receive an
automobile allowance of $500 per month payable in accordance with the general
payroll practices of the Corporation in effect from time to time.

     3.3  Vacation.  Employee shall be entitled to four (4) weeks paid vacation
during each full 12-month period during the term hereof; provided, however that
in taking such vacation Employee shall give and exercise reasonable
consideration to and for the needs and interests of Corporation. Employee shall
also be entitled to such other vacation time and paid holidays, if any, as shall
from time to time be determined by the Corporation.

                                      -2-
<PAGE>
 
     3.4  Employee Benefit Plans.  Employee shall be included in all of the
employee benefit plans existing now or in the future providing pension, thrift,
profit sharing, bonus or similar benefits as they are provided generally to
officers of the Corporation, subject to the terms and conditions of all such
plans.  In addition, Employee shall be eligible to participate in all executive
compensation programs or other perquisites available to other officers of
Corporation, subject to the terms and conditions of such programs.

     3.5  Insurance and Welfare Benefit Plans.  Corporation shall cover Employee
under its group dental, medical and hospitalization plans, shall provide
Employee term life insurance coverage, and will cover Employee under other
insurance and employee welfare benefit plans maintained for its officers
generally.  Corporation shall also use its best efforts to evaluate and provide
disability insurance coverage and life insurance coverage which are payable to
the beneficiary of employee's choice.

     3.6  Place of Performance.  The headquarters for the performance of
Employee's duties shall be located in The Woodlands, Texas, and/or other office
location of the Corporation within the metropolitan Houston area, but from time
to time Employee shall be required to travel to other locations in the proper
conduct of his responsibilities under this Agreement.  As it is Corporation's
intention to expand the business of Corporation on a national scale, Corporation
may require Employee to spend a reasonable amount of time traveling, as his
duties and the business of Corporation and its affiliates or subsidiaries may
require.

     3.7  Stock Option Awards, Other Awards.  The Board of Directors or its
Compensation Committee, as the case may be, shall consider Employee for the
grant of options to purchase common stock or other awards, as Employee's
performance dictates, no less frequent than annually during the term of this
Agreement under any plan of the Corporation which provides for such stock
options or other awards. Unless modified by the Board of the Directors any
awards granted to Employee pursuant to any other such plans adopted by the
Corporation (the "Incentive Plans") shall be immediately vested in full and
exercisable upon the occurrence of any of the following:  (i) any Change of
Control (as defined herein); (ii) termination of Employee by the Corporation
without just cause (as defined herein); (iii) any substantial or material
diminishment in Employee's reporting responsibilities as designated in this
Agreement; (iv) Employee's death; or (v) at the termination of this agreement
due to Employee's disability as defined in Section 4.2 of this agreement.  Any
agreement for an award under the Incentive Plans granted to Employee shall
reflect the provisions of this Section 3.7.

 
     3.8  Incentive Bonus. Employee shall receive a bonus of $125,000 for 1997,
payable no later than the end of January 1998; provided, however, that this
bonus shall be payable only if, prior to January 1, 1998, Corporation has become
subject to the reporting requirements of the Securities Exchange Act of 1394.
Beginning in 1998, Employee shall be eligible to receive a bonus of up to 75% of
annual base salary as an annual incentive bonus subject to the achievement of
certain performance goals established by the Board of Directors as discussed
below. The bonus for 1998 shall be paid no later than the end of January, 1999.
The bonus shall be based on attainment of performance goals to be established no
later than the end of the first quarter of each calendar year, subject to
approval of those performance goals by the Board of

                                      -3-
<PAGE>
 
Directors, which will provide for at least the following: (i) financial targets;
(ii) operating targets, and (iii) exploration success targets.

 4.  TERMINATION OF AGREEMENT.  This Agreement will continue in effect until
the expiration of the term stated in Section 1 hereof unless sooner terminated
as set forth below.  If such termination occurs, Employee shall continue to be
subject to Section 5 hereof.

     4.1  Death of Employee.  If Employee shall terminate employment due to
death during the term of this Agreement, this Agreement shall terminate and his
spouse, if she is then surviving or if not, his legal representative, shall be
entitled to receive in one lump sum a pro rata share of incentive compensation
under Section 3.8 based on the number of days in the year that elapsed prior to
death and as if all performance goals had been met.

     4.2  Illness or Other Incapacity.  If during the term of this Agreement,
Employee shall fail to perform his duties hereunder as a result of illness or
other incapacity and such illness or incapacity shall continue for a period of
more than three (3) months, Corporation shall have the right to terminate this
Agreement and the employment hereunder as of date to be specified in a notice of
termination, such date to be not less than thirty (30) days after the mailing by
certified mail of such notice.  If Employee's illness or incapacity shall have
ended, and the Employee shall have assumed his duties hereunder, prior to the
date specified in the notice of termination, he shall be entitled to resume his
employment hereunder as if such notice had not been given.  If such termination
occurs, Employee shall continue to be bound by the covenants contained in
Section 5 hereof, but in all other regards, this Agreement shall terminate as of
such termination date, and Corporation shall pay to Employee or his legal
representative (i) compensation provided for in Section 3.1 of this Agreement
for the remaining term of this Agreement, but in no event less than one year, if
the Corporation has not provided disability insurance pursuant to Section 3.5
(ii) a pro rata share of incentive compensation under Section 3.8 based on the
number of days in the year that elapsed prior to such termination and as if all
performance goals had been met, and (iii) such other benefits, if any, as may be
determined by Corporation.
 
     4.3  Termination by Corporation for Cause.  Corporation may terminate this
Agreement and the employment of Employee by service of written notice of
termination to Employee specifying the circumstances and an effective date for
such termination upon the earlier to occur of any of the following events: (i)
Employee willfully misappropriates the property of Corporation or commits any
other act of dishonesty which results in injury to Corporation or reasonably
could result in injury to Corporation; (ii) Employee engages in personal
misconduct which results in material injury to Corporation, or could reasonably
result in material injury to Corporation unless Employee in good faith
reasonably believed that his actions were in the best interest of Corporation,
(iii) Employee is convicted of a felony; or (iv) the Board of Directors had
determined in good faith that Employee has failed to diligently perform his
duties hereunder as specified by Corporation and in a manner consistent with
prudent business practice and such failure continues after Employee has been
given at least ten (10) days written notice of the failure.  In the event this
Agreement is terminated for cause set forth in paragraphs (i) through (iv) above
by the Corporation prior to the conclusion of the term of this Agreement, the

                                      -4-
<PAGE>
 
Corporation shall have no further obligation hereunder, except for its payment
of the compensation provided for in Section 3.1 of this Agreement for a period
of three (3) months following such termination, which compensation shall be
considered a debt of the Corporation and shall not be discharged by reason of
termination of Employee's employment.


     4.4  Termination by Corporation for Other than Cause.  In the event
Corporation terminates Employee's employment for any reason other than under
Section 4.3, Employee shall be entitled to a payment from Corporation in an
amount equal to the Termination Payment (as hereinafter defined).  For purposes
of this Agreement, the term "Termination Payment" shall mean an amount equal to
the sum of (i) all base salary that would have been paid to Employee pursuant to
Section 3.1 during the balance of the term of employment provided for in Section
1.2 (but in no event less than 12 months of such base salary) (the "Salary
Portion"), and (ii) subject to the execution by Employee of a waiver and release
of all claims against Corporation, all incentive compensation that would have
been paid to Employee pursuant to Section 3.8as if all performance goals have
been met during the balance of the term provided for in Section 1.2 (but in no
event less than one (1) such annual incentive bonus) (the "Bonus Portion").  The
Termination Payment shall be paid (i) with respect to the Bonus Portion, in one
(1) lump sum cash payment within five (5) days after Employee has signed a
release and any applicable revocation period has expired and (ii) with respect
to the Salary Portion, in one (1) lump sum cash payment within five (5) days
after such termination of employment.

     4.5  Termination Following Change of Control.  In the event that a "Change
of Control" (as hereinafter defined) occurs and, and within one (1) year
following such Change of Control, Employee's employment is terminated by
Corporation for a reason other than as described in Section 4.3, or he
voluntarily terminates employment due to a substantial diminishment in his job
responsibilities or duties or a material breach by Corporation of any material
provision of this Agreement or any other agreement with Employee which remains
uncorrected for ten (10) days following written notice of such diminishment or
breach by Employee to Corporation, then, in lieu of any payments pursuant to
Sections 4.4 or 4.6 hereof, Employee shall be entitled to a Termination Payment
under terms and conditions applicable pursuant to Section 4.4, provided that the
reference therein to 12 months shall be deemed to be a reference to 24 months
and the reference to one such annual incentive bonus shall be deemed to be a
reference to two such annual incentive bonuses.  A "Change of Control" shall
mean (i) any sale by Corporation of substantially all of its assets or, (ii) the
removal or failure to re-elect R.A. Krenzke as a member of the Board of
Directors for any reason other than resignation, voluntary removal, termination
by Corporation for cause, disability or death, provided the South Coast owners
have the right to a Board seat pursuant to the Acquisition Agreement and Plan of
Organization dated August 19, 1997 or (iii) the acquisition by any "person,"
including a "group" as determined in accordance with Section 13(d)(3) of the
Securities Exchange Act of 1934, of beneficial ownership, directly or
indirectly, of securities of Corporation representing 50% or more of the
combined voting power of Corporation's then outstanding securities; provided,
however, that no Change of Control shall be deemed to occur if beneficial
ownership in Corporation's then outstanding securities is acquired pursuant to
any reorganization of Corporation or recapitalization, spinoff or other
transaction if, after giving effect to such

                                      -5-
<PAGE>
 
transaction, however structured, at least 50% of the outstanding voting
securities with the ultimate parent entity corporation are beneficially owned in
the aggregate, directly or indirectly through one or more intermediaries, by the
former shareholders of the Corporation.

     4.6  Termination by Employee for Good Reason.  If Employee's employment
hereunder shall be terminated by Employee due to a substantial diminishment in
Employee's job responsibilities or duties or a material breach by Corporation of
any material provision of this Agreement or any other agreement with Employee
which remains uncorrected for ten (10) days following written notice of such
diminishment or breach by Employee to Corporation, then Employee shall be
entitled to a Termination Payment under terms and conditions applicable pursuant
to Section 4.4.

     4.7  Voluntary Termination by Employee.  Notwithstanding any provision
herein to the contrary, Employee shall have the right to terminate his
employment under this Agreement at any time and for any reason whatsoever.  If
Employee's employment hereunder shall be terminated by Employee for any reason
whatsoever other than the reasons specified in Sections 4.1, 4.2, 4.5 or 4.6,
then, upon such termination, all compensation and all benefits to Employee
hereunder shall terminate contemporaneously with the termination of such
employment. However, in the event Corporation has not become subject to the
reporting requirements of the Securities Exchange Act of 1934 within one (1)
year of the effective date of this Agreement and Employee has remained an
employee of the Corporation for at least one (1) year prior to such termination,
Employee shall be entitled to receive an amount equal to twelve (12) months of
his annual base salary then in effect, which shall be paid in one lump sum
within five (5) days after such time of termination.

     4.8  No Duty to Mitigate Losses.  Employee shall have no duty to find new
employment following the termination of his employment under circumstances which
required Corporation to pay any amount to Employee pursuant to this Section 4.
Any salary or remuneration received by Employee from a third party for the
providing of personal services (whether by employment or by functioning as an
independent contractor) following the termination of his employment under
circumstances pursuant to which Sections 4.2, 4.4, 4.5, 4.6 or 6.7 apply shall
not reduce Corporation's obligation to make a payment to Employee (or the amount
of such payment) pursuant to the terms of any such Section.

     4.9  Liquidated Damages.  In light of the difficulties in estimating the
damages for an early termination of this Agreement, Corporation and Employee
hereby agree that the payments, if any, to be received by Employee pursuant to
Sections 4.1, 4.2, 4.4, 4.5, 4.6 or 6.7 shall be received by Employee as
liquidated damages.

     4.10  Incentive and Deferred Compensation.  This Agreement governs the
rights and obligations of Employee and Corporation with respect to Employee's
base salary, incentive compensation pursuant to Section 3.8 and certain

 5.  AGREEMENT RESTRICTING TRADE SECRETS AND COMPETITION.

     5.1  Confidential Information and Trade Secrets.  Employee acknowledges
that he will have access to and that there will be disclosed to him during the
course of this employment, information of a proprietary nature owned by
Corporation, which is of a confidential nature and all of which have great value
to Corporation and which is a substantial basis and foundation upon which
Corporation's business is predicated.  Employee acknowledges that except for his
employment and the duties assigned to him which he will be fulfilling, that he
would not otherwise have access to the foregoing information.  Employee agrees
that any and all confidential knowledge or information which may be obtained by
him in the course of his employment will be held inviolate by him and that he
will conceal the same from any and all other persons, including, but not limited
to, competitors of Corporation, and that he will not impart any such knowledge
acquired by him as an employee of Corporation to anyone whomsoever either during
this employment or after his employment by Corporation has terminated, except to
the extent (i) such disclosure is required by law, (ii) such information is
otherwise made public by Corporation (other than by Employee in violation
thereof), or (iii) such disclosure is made in the normal course of business and
is consistent with Corporation's interests.

     Employee agrees that upon termination of his employment hereunder he will
immediately surrender and turn over to Corporation all books, records, forms,
data, electric logs, geological maps, scout cards, seismic tapes and all papers
and writings relating to the business of Corporation and other information which
reflects or reveals Corporation's confidential or trade secret information
protected by this Section, and all other property belonging to Corporation, it
being understood and agreed that the same are the sole property of Corporation
and that Employee will not make any copies thereof; provided, however, the
parties agree that Employee's personnel files and any logs, records, and maps
which were Employee's property prior to the Effective Date shall remain
Employee's property.  For purposes of this Section 5, the term "Corporation"
shall include Corporation as herein defined and any of its subsidiaries,
affiliates or parent organizations.

     5.2  Noncompetition Agreement.  Except as provided in Section 2.1, for so
long as this Agreement is in effect and for a period of six (6) months after
termination of his employment, Employee will not, without Corporation's written
permission, directly or indirectly, own, manage, operate, control, be employed
by, participate in or be connected in any manner with the ownership, management,
operation, or control of any business which is in direct competition with
Corporation, specifically with respect to the geologic prospects or any planned
or completed acquisitions (of stock, equity or assets) in or through which
Corporation does explore, develop or produce oil and gas or has current plans to
explore, develop or produce oil and gas. Corporation shall within ten (10) days
of Employee's termination of employment with the Corporation provide Employee
with a complete list of any properties, prospects, acquisitions, data
acquisitions, corporate transactions or other financial or business arrangements
contemplated by the Corporation to which the preceding sentence applies.
Employee must approve in writing,

                                      -7-
<PAGE>
 
and no such approval can be reasonably withheld, to the listing provided by the
Corporation. Any disputes which cannot be settled will be handled as provided in
Section 6.10 of this Agreement. For so long as this Agreement is in effect and
for a period of six (6) months after termination of his employment, Employee
shall refrain from contacting or encouraging any third party to contact any
individual who is employed by Corporation or its affiliates for the purpose of
recruiting or placing that individual with any other employer.

     5.3  Injunctive Relief.  Employee specifically acknowledges and agrees that
the remedy at law for any breach of the provisions of Sections 5.1 or 5.2 will
be inadequate and that Corporation shall be entitled to temporary and permanent
injunctive relief without the necessity of proving actual damage.

     5.4  Reformation.  In the event that the provisions of this Section 5
should ever be deemed to exceed the time or geographic limitations permitted by
applicable law, then such provision shall be deemed reformed to the maximum time
or geographic limitations permitted by applicable law.

 
6.  GENERAL.

     6.1  Indemnity and Directors' & Officers' Liability Insurance Coverage.
Corporation agrees to indemnify and defend Employee, at Corporation's sole
expense, in any matters arising from Employee's performance of his duties as an
employee, officer or director of Corporation or any of Corporation's
subsidiaries or affiliates to the fullest extent permitted by law.  The
Corporation will take reasonable steps to obtain Directors' and Officers'
liability insurance prior to becoming subject to the reporting requirements of
the Securities Exchange Act of 1934.

     6.2  Headings.  Section headings are included solely for convenience and
should not be used in the interpretation of this Agreement.

     6.3  Severability.  In the event any one or more of the provisions
contained in the Agreement shall, for any reason, be held to be invalid, illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability
shall not effect any other provisions of this Agreement, and this Agreement
shall be construed in all respects as if such invalid or unenforceable
provisions were omitted.

     6.4  Notices.  Any notice, demand and all other communications required or
permitted to be given under this Agreement shall be in writing and shall have
been deemed duly given when delivered or (unless otherwise specified herein)
three (3) business days after mailed by United States registered mail, return
receipt requested, postage prepaid, to the address set forth on the signature
page hereof, or to such other address as any party may have furnished to the
other in writing in accordance herewith, except that notices of change of
address shall be effective only upon receipt.

     6.5  Waiver of Breach; Expenses.  The waiver by Employee or Corporation of
a breach of any provision of this Agreement shall not operate or be construed as
a waiver of any subsequent breach.  In any action brought by any party hereto
pursuant to Section 6.10 of the Agreement, the prevailing party shall be
entitled to collect such party's reasonable attorney's fees, court costs and
expenses in such action.
 
     6.6  Binding Effect; Assignment.  The respective rights and obligations of
Corporation and Employee under the Agreement shall inure to the benefit of and
shall be binding upon Corporation and the respective successors and assigns of
Corporation.  This Agreement shall not be assignable by Employee.  As used
herein, the term "successors and assigns" shall include any corporation or
corporations which acquire all or substantially all of the assets and businesses
of Corporation whether by purchase, merger, consolidation or otherwise.  The
parties hereto presently contemplate that Corporation will enter into certain
transactions resulting in a reorganization of Corporation and in connection
therewith this Agreement shall automatically be assigned to the parent of
Corporation and all references herein to Corporation shall thereafter be deemed
to be references to such parent entity.

     6.7  Certain Additional Payments by Company.  Notwithstanding anything to
the contrary in this Agreement, in the event that any payment or distribution by
Corporation to or for the benefit of Employee, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise (a "Payment") would be subject to the excise tax imposed by Section
4999 of the Internal Revenue Code of 1986, as amended, or any interest or
penalties with respect to such excise tax (such excise tax, together with any
such interest or penalties, are herein collectively referred to as the "Excise
Tax"), Corporation shall pay to Employee an additional payment (a "Gross-up
Payment") in an amount such that after payment by employee of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax imposed on any Gross-up Payment, Employee retains an
amount of the Gross-up Payment equal to the Excise Tax imposed upon the
Payments.  Corporation and Employee shall make an initial determination as to
whether a Gross-Up Payment is required and the amount of any such Gross-Up
Payment.  Employee shall notify Corporation in writing of any claim by the
Internal Revenue Service which, if successful, would require Corporation to make
a Gross-Up Payment (or a Gross-Up Payment in excess of that, if any, initially
determined by Corporation and Employee) within ten (10) days of the receipt of
such claim.  Corporation shall notify Employee in writing at least ten days
prior to the due date of any response required with respect to such claim if it
plans to contest the claim.  If Corporation decides to contest such claim,
Employee shall cooperate fully with Corporation in such action; provided,
however, Corporation shall bear and pay directly or indirectly all costs and
expenses (including additional interest and penalties) incurred in connection
with such action and shall indemnify and hold Employee harmless, on an after-tax
basis, for any Excise Tax or income tax, including interest and penalties with
respect thereto, imposed as a result of Corporation's action.  If, as a result
of Corporation's action with respect to a claim, Employee receives a refund of
any amount paid by Corporation with respect to such claim, Employee shall
promptly pay such refund to Corporation.  If Corporation fails to timely notify
Employee whether it will contest such claim or Corporation determines not to
contest such claim, then Corporation shall immediately pay to Employee the
portion of such claim, if any, which it has not previously paid to Employee.

     6.8  Entire Agreement Counterparts.  Except as provided in (i) the
benefits, plans, and programs, if any, referenced in Sections 3.4, 3.5, 3.7 and
3.8 hereof and (ii) any signed written agreements contemporaneously or hereafter
executed by Corporation and Employee, this Agreement contains the entire
agreement of the parties hereto, notwithstanding any oral representation of the
parties to the contrary.  This Agreement supersedes as of the Effective Date all
agreements, oral or in writing, and other arrangements between the parties with
respect to all matters related to the subject matter hereof.  This Agreement may
be executed in multiple counterparts, all of which shall constitute one
Agreement, but both parties must execute and deliver one signed counterpart
before this Agreement is effective.

     6.9  Applicable Law.  The execution, performance and enforcement of this
Agreement shall be governed by and construed in accordance with the internal
laws of the State of Texas without giving effect to its conflict of laws
provision.

     6.10  Claims; Arbitration.

     (a) All claims by Employee for compensation and benefits under this
Agreement shall be directed to and determined by the Board of Directors and
shall be in writing.  Any denial by the Board of Directors of a claim for
benefits under this Agreement shall be delivered to Employee in writing and
shall set forth the specific reasons for the denial and specific provisions of
this Agreement relied upon.  The Board of Directors shall afford a reasonable
opportunity to Employee for a review of a decision denying a claim and shall
further allow Employee to appeal to the Board of Directors a decision of the
Board of Directors within 60 days after notification by the Board of Directors
that Employee's claim has been denied.

     (b) To the extent permitted by applicable law, any further dispute or
controversy arising under or in connection with this Agreement shall be settled
exclusively by arbitration in Houston, Texas, in accordance with the rules of
the American Arbitration Association then in effect.  The agreement set forth
herein to arbitrate shall be specifically enforceable under the prevailing
arbitration law.

     (c) Notice of the demand for arbitration shall be filed in writing with the
other party to this Agreement and with the American Arbitration Association.
The demand for arbitration shall be made within a reasonable time after the
claim, dispute or other matter in question has arisen, and in no event shall it
be made after the date when institution of legal or equitable proceedings based
on such claim, dispute or other matter in question would be barred by the
applicable statute of limitations.

     (d) The award rendered by the arbitrator shall be final and judgment may be
entered upon it in accordance with applicable law in any court having
jurisdiction thereof.

     (e) Unless otherwise agreed in writing, Corporation shall continue to make
payments and provide benefits in accordance with this Agreement, and Employee
shall continue to perform his obligations hereunder during any arbitration
proceedings.

          2.2   Employer-Employee Relationship.  The relationship between

subsidiaries or affiliates.  Corporation agrees to endeavor to obtain Directors'

Corporation's IPO.

continue to be subject to Section 5 hereof.

<PAGE>
 
          4.2   Illness or Other Incapacity.  If during the term of this
Agreement, Employee shall fail to perform his duties hereunder as a result of
illness or other incapacity and such illness or incapacity shall continue for a
period of more than three (3) months, Corporation shall have the right to
terminate this Agreement and the employment hereunder as of date to be specified
in a notice of termination, such date to be not less than thirty (30) days after
the mailing by certified mail of such notice.  If Employee's illness or
incapacity shall have ended, and the Employee shall have assumed his duties
hereunder, prior to the date specified in the notice of termination, he shall be
entitled to resume his employment hereunder as if such notice had not been
given.  If such termination occurs, Employee shall continue to be bound by the
covenants contained in Sections 5 and 6 hereof, but in all other regards, this
Agreement shall terminate as of such termination date, and Corporation shall pay
to Employee or his successor the amount of any accrued but unpaid compensation
under Section 3.1 hereof, and such other benefits, if any, as may be determined
by Corporation.

          4.3   Termination by Corporation for Cause.  Corporation may
terminate this Agreement and the employment of Employee by service of written
notice of termination to Employee specifying the circumstances and an effective
date for such termination upon the earlier to occur of any of the following
events:  (i)   the Employee willfully misappropriates the property of
Corporation or commits any other act of dishonesty which results in injury to
the Corporation or reasonably could result in injury to Corporation; (ii) the
Employee engages in personal misconduct which results in injury to the
Corporation, or could reasonably could result in injury to Corporation; (iii)
the Employee violates any law or regulation relating to the business of the
Corporation which results in injury to the Corporation or reasonably could
result in injury to the Corporation; (iv) Employee fails to diligently perform
his duties hereunder as specified by Corporation and in a manner consistent with
prudent business practice.  In the event this Agreement is terminated for cause
set forth in paragraphs (i) through (iv) above, Corporation will have no
obligation to provide any further salary payments or other benefits to Employee,
including, but not limited to salary, overriding royalty interests under the
Plan and incentive compensation, for any period after the effective date of such
termination.

          4.4  Termination by Corporation for Other than Cause.  In the event
Corporation terminates for any reason other than under paragraph 4.3, Employee
shall be entitled to a payment of twelve month's current salary, payable within
thirty (30) days of termination, and to exercise any vested Option pursuant to
the terms of Corporation's Option plan (including the portion that would be
vested for the year in which termination occurs with vesting applied on a pro
rata daily basis assuming 365 days between vesting dates).

               COMPETITION

               5.1  Confidential Information and Trade Secrets.  Employee
acknowledges that he will have access to and that there will be disclosed to him
during the course of this employment, information of a proprietary nature owned
by Corporation, which is of a confidential nature and all of which have great
value to Corporation and which is a substantial basis and foundation upon which
Corporation's business is predicated.  Employee acknowledges that except for his
employment and the duties assigned to him which he will be fulfilling, that he
would not otherwise have access to the foregoing information.  Employee agrees
that any and all confidential knowledge or information which may be obtained by
him in the course of his employment will be held inviolate by him and that he
will conceal the same from any and all other persons, including, but not limited
to, competitors of Corporation, and that he will not impart any such knowledge
acquired by him as an employee of Corporation to anyone whomsoever either during
this employment or after his employment by Corporation has terminated, except to
the extent (i) such disclosure is required by law, (ii) such information is
otherwise made public by the Corporation, or (iii) such disclosure is made in
the normal course of business and is consistent with Corporation's interests.

               Employee agrees that upon termination of his employment hereunder
he will immediately surrender and turn over to Corporation all books, records,
forms data, electric logs, geologic maps, scout cards, seismic tapes and all
papers and writing relating to the business of Corporation and other information
which reflects or reveals Corporation's confidential or trade secret information
protected by this Section, and all other property belonging to Corporation, it
being understood and agreed that the same are the sole property of Corporation
and that Employee will not make any copies thereof; provided, however, the
parties agree that the Employee's personnel files and any logs, records, and
maps which were Employee's property prior to the Effective Date shall remain
Employee's property. For purposes of this Section 5, the term "Corporation"
shall include Corporation as heretofore defined and any of its subsidiaries,
affiliates or parent organizations.

               5.2  Noncompetition Agreement.  For so long as this Agreement is
in effect and for a period of six (6) months after termination of this
Agreement, Employee will not, without Corporation's written permission, directly
or indirectly, own, manage, operate, control, be employed by, participate in or
be connected in any manner with the ownership, management, operation, or control
of any business which is in direct competition with the Corporation,
specifically in the geologic trends which Corporation explores, develops or
produces oil and gas.

<PAGE>
 
               5.3  Injunctive Relief.  Employee specifically acknowledges and
agrees that the remedy at law for any breach of the provisions of Sections 5.1
or 5.2 will be inadequate and that Corporation shall be entitled to temporary
and permanent injunctive relief without the necessity of proving actual damage.

               5.4  Reformation.  In the event that the provisions of this
Section 5 should ever be deemed to exceed the time or geographic limitations
permitted by applicable law, then such provisions shall be deemed reformed to
the maximum time or geographic limitations permitted by applicable law.

performance of Employee's duties hereunder, or conflict with the business of the
Corporation, its subsidiaries, or affiliates The voluntary performance by

time necessary to perform his duties hereunder.

     2.2  Employer-Employee Relationship.  The relationship between Corporation
and Employee is that of an employer and employee.  Corporation shall have the
right to instruct, control, review and, subject to the terms of this Agreement,

Agreement and the employment of Employee by service of written notice of
termination to Employee specifying the circumstances and an effective date for

other act of dishonesty which results in injury to Corporation or reasonably

result in material injury to Corporation unless Employee in good faith
reasonably believed that his actions were in the best interest of Corporation,
(iii) Employee is convicted of a felony; or (iv) the Board of Directors had
determined in good faith that Employee has failed to diligently perform his
duties hereunder as specified by Corporation and in a manner consistent with
prudent business practice and such failure continues after Employee has been

Agreement is terminated for cause set forth in paragraphs (i) through (iv) above
by the Corporation prior to the conclusion of the term of this Agreement, the
Corporation shall have no further obligation hereunder, except for its payment

                                      -4-
<PAGE>

Corporation and shall not be discharged by reason of termination of Employee's
employment.

     4.4  Termination by Corporation for Other than Cause.  In the event
Corporation terminates Employee's employment for any reason other than under
Section 4.3, Employee shall be entitled to a payment from Corporation in an
amount equal to the Termination Payment (as hereinafter defined).  For purposes
of this Agreement, the term "Termination Payment" shall mean an amount equal to
the sum of (i) all base salary that would have been paid to Employee pursuant to

"Salary Portion"), and (ii) subject to the execution by Employee of a waiver and
release of all claims against Corporation, all incentive compensation that would

had been met during the balance of the term provided for in Section 1.2 (but in
no event less than one (1) such annual incentive bonus) (the "Bonus Portion").
The Termination Payment shall be paid (i) with respect to the Bonus Portion, in
one (1) lump sum cash payment within five (5) days after Employee has signed a
release and any applicable revocation period has expired and (ii) with respect
to the Salary Portion, in one (1) lump sum cash payment within five (5) days
after such termination of employment.

     4.5  Termination Following Change of Control.  In the event that a "Change
of Control" (as hereinafter defined) occurs and, within one (1) year following
such Change of Control, Employee's employment is terminated by Corporation for a
reason other than as described in Section 4.3, or he voluntarily terminates
employment due to a substantial diminishment in his job responsibilities or
duties or a material breach by Corporation of any material provision of this
Agreement or any other agreement with Employee which remains uncorrected for ten
(10) days following written notice of such diminishment or breach by Employee to
Corporation, then, in lieu of any payments pursuant to Sections 4.4 or 4.6
hereof, Employee shall be entitled to a Termination Payment under terms and
conditions applicable pursuant to Section 4.4, provided that the reference
therein to 12 months shall be deemed to be a reference to 24 months and the
reference to one such annual incentive bonus shall be deemed to be a reference
to two such annual incentive bonuses.  A "Change of Control" shall mean (i) any
sale by Corporation of substantially all of its assets or, (ii) the removal or
failure to re-elect R.A. Krenzke as a member of the Board of Directors for any

August 19, 1997 or (iii) the acquisition by any "person," including a "group" as
determined in accordance with Section 13(d)(3) of the Securities Exchange Act of
1934, of beneficial ownership, directly or indirectly, of securities of
Corporation representing 50% or more of the combined voting power of
Corporation's then outstanding securities; provided, however, that no Change of
Control shall be deemed to occur if beneficial ownership in Corporation's then
outstanding securities is acquired pursuant to any reorganization of Corporation
or recapitalization, spinoff or other transaction if, after giving effect to
such transaction, however structured, at least 50% of the outstanding voting
securities with the 

                                      -5-

ultimate parent entity corporation are beneficially owned in the aggregate,
directly or indirectly through one or more intermediaries, by the former
shareholders of the Corporation.

     4.6  Termination by Employee for Good Reason.  If Employee's employment
hereunder shall be terminated by Employee due to a substantial diminishment in
Employee's job responsibilities or duties or a material breach by Corporation of
any material provision of this Agreement or any other agreement with Employee
which remains uncorrected for en (10) days following written notice of such
diminishment or breach by Employee to Corporation, then Employee shall be
entitled to a Termination Payment under terms and conditions applicable pursuant
to Section 4.4.

     4.7  Voluntary Termination by Employee.  Notwithstanding any provision
herein to the contrary, Employee shall have the right to terminate his
employment under this Agreement at any time and for any reason whatsoever.  If
Employee's employment hereunder shall be terminated by Employee for any reason
whatsoever other than the reasons specified in Sections 4.1, 4.2, 4.5 or 4.6,
then, upon such termination, all compensation and all benefits to Employee
hereunder shall terminate contemporaneously with the termination of such
employment. However, in the event Corporation has not become subject to the
reporting requirements of the Securities Exchange Act of 1934 within one (1)
year of the effective date of this Agreement and Employee has remained an
employee of the Corporation for at least one (1) year prior to such termination,
Employee shall be entitled to receive an amount equal to twelve (12) months of
his annual base salary then in effect, which shall be paid in one lump sum
within five (5) days after such time of termination.

     4.8  No Duty to Mitigate Losses.  Employee shall have no duty to find new
employment following the termination of his employment under circumstances which
required Corporation to pay any amount to Employee pursuant to this Section 4.
Any salary or remuneration received by Employee from a third party for the
providing of personal services (whether by employment or by functioning as an
independent contractor) following the termination of his employment under
circumstances pursuant to which Sections 4.2, 4.4, 4.5, 4.6 or 6.7 apply shall
not reduce Corporation's obligation to make a payment to Employee (or the amount
of such payment) pursuant to the terms of any such Section.

     4.9  Liquidated Damages.  In light of the difficulties in estimating the
damages for an early termination of this Agreement, Corporation and Employee
hereby agree that the payments, if any, to be received by Employee pursuant to
Sections 4.1, 4.2, 4.4, 4.5, 4.6 or 6.7 shall be received by Employee as
liquidated damages.

     4.10  Incentive and Deferred Compensation.  This Agreement governs the
rights and obligations of Employee and Corporation with respect to Employee's
base salary, incentive compensation pursuant to Section 3.8 and certain
perquisites of employment.  Employee's rights and obligations both during the

stock, incentive and deferred compensation (other than incentive compensation
payable pursuant to Section 3.8), life insurance policies insuring the life of
Employee, and other 

                                      -6-
<PAGE>
 
benefits under the plans and programs maintained by Corporation shall be
governed by the separate agreements, plans and other documents and instruments
governing such matters.

     5.1  Confidential Information and Trade Secrets.  Employee acknowledges
that he will have access to and that there will be disclosed to him during the
course of this employment, information of a proprietary nature owned by
Corporation, which is of a confidential nature and all of which have great value
to Corporation and which is a substantial basis and foundation upon which
Corporation's business is predicated.  Employee acknowledges that except for his
employment and the duties assigned to him which he will be fulfilling, that he
would not otherwise have access to the foregoing information.  Employee agrees
that any and all confidential knowledge or information which may be obtained by
him in the course of his employment will be held inviolate by him and that he
will conceal the same from any and all other persons, including, but not limited
to, competitors of Corporation, and that he will not impart any such knowledge
acquired by him as an employee of Corporation to anyone whomsoever either during
this employment or after his employment by Corporation has terminated, except to
the extent (i) such disclosure is required by law, (ii) such information is
otherwise made public by Corporation (other than by Employee in violation
thereof), or (iii) such disclosure is made in the normal course of business and
is consistent with Corporation's interests.

     Employee agrees that upon termination of his employment hereunder he will
immediately surrender and turn over to Corporation all books, records, forms,
data, electric logs, geological maps, scout cards, seismic tapes and all papers
and writings relating to the business of Corporation and other information which
reflects or reveals Corporation's confidential or trade secret information
protected by this Section, and all other property belonging to Corporation, it
being understood and agreed that the same are the sole property of Corporation
and that Employee will not make any copies thereof; provided, however, the
parties agree that Employee's personnel files and any logs, records, and maps
which were Employee's property prior to the Effective Date shall remain
Employee's property.  For purposes of this Section 5, the term "Corporation"
shall include Corporation as herein defined and any of its subsidiaries,
affiliates or parent organizations.

     5.2  Noncompetition Agreement.  Except as provided in Section 2.1, for so
long as this Agreement is in effect and for a period of six (6) months after
termination of his employment, Employee will not, without Corporation's written
permission, directly or indirectly, own, manage, operate, control, be employed
by, participate in or be connected in any manner with the ownership, management,
operation, or control of any business which is in direct competition with
Corporation, specifically with respect to the geologic prospects or any planned
or completed acquisitions (of stock, equity or assets) in or through which
Corporation does explore, develop or produce oil and gas or has current plans to
explore, develop or produce oil and gas. Corporation shall within ten (10) days
of Employee's termination of employment with the Corporation provide Employee
with a complete list of any properties, prospects, acquisitions, data
acquisitions, corporate transactions or other financial or business arrangements
contemplated by the Corporation to which the preceding sentence applies.
Employee must approve in writing, 

                                      -7-
<PAGE>
 
and no such approval can be reasonably withheld, to the listing provided by the
Corporation. Any disputes which cannot be settled will be handled as provided in
Section 6.10 of this Agreement. For so long as this Agreement is in effect and
for a period of six (6) months after termination of his employment, Employee
shall refrain from contacting or encouraging any third party to contact any
individual who is employed by Corporation or its affiliates for the purpose of
recruiting or placing that individual with any other employer.

     5.3  Injunctive Relief.  Employee specifically acknowledges and agrees that
the remedy at law for any breach of the provisions of Sections 5.1 or 5.2 will
be inadequate and that Corporation shall be entitled to temporary and permanent
injunctive relief without the necessity of proving actual damage.

     5.4  Reformation.  In the event that the provisions of this Section 5
should ever be deemed to exceed the time or geographic limitations permitted by
applicable law, then such provision shall be deemed reformed to the maximum time
or geographic limitations permitted by applicable law.

     6.  GENERAL.

     6.1  Indemnity and Directors' & Officers' Liability Insurance Coverage.

Corporation will take reasonable steps to obtain Directors' and Officers'
liability insurance prior to becoming subject to the reporting requirements of
the Securities Exchange Act of 1934.

     6.2  Headings.  Section headings are included solely for convenience and
should not be used in the interpretation of this Agreement.

     6.3  Severability.  In the event any one or more of the provisions
contained in the Agreement shall, for any reason, be held to be invalid, illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability

shall be construed in all respects as if such invalid or unenforceable
provisions were omitted.

     6.4  Notices.  Any notice, demand and all other communications required or
permitted to be given under this Agreement shall be in writing and shall have
been deemed duly given when delivered or (unless otherwise specified herein)

pursuant to Section 6.10 of the Agreement, the prevailing party shall be
entitled to collect such party's reasonable attorney's fees, court costs and
expenses in such action.

     6.6  Binding Effect; Assignment.  The respective rights and obligations of
Corporation and Employee under the Agreement shall inure to the benefit of and
shall be binding upon Corporation and the respective successors and assigns of
Corporation.  This Agreement shall not be assignable by Employee.  As used
herein, the term "successors and assigns" shall include any corporation or
corporations which acquire all or substantially all of the assets and businesses
of Corporation whether by purchase, merger, consolidation or otherwise.  The
parties hereto presently contemplate that Corporation will enter into certain
transactions resulting in a reorganization of Corporation and in connection
therewith this Agreement shall automatically be assigned to the parent of
Corporation and all references herein to Corporation shall thereafter be deemed
to be references to such parent entity.

     6.7  Certain Additional Payments by Company.  Notwithstanding anything to
the contrary in this Agreement, in the event that any payment or distribution by
Corporation to or for the benefit of Employee, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise (a "Payment") would be subject to the excise tax imposed by Section
4999 of the Internal Revenue Code of 1986, as amended, or any interest or
penalties with respect to such excise tax (such excise tax, together with any
such interest or penalties, are herein collectively referred to as the "Excise
Tax"), Corporation shall pay to Employee an additional payment (a "Gross-up
Payment") in an amount such that after payment by employee of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax imposed on any Gross-up Payment, Employee retains an
amount of the Gross-up Payment equal to the Excise Tax imposed upon the
Payments.  Corporation and Employee shall make an initial determination as to
whether a Gross-Up Payment is required and the amount of any such Gross-Up
Payment.  Employee shall notify Corporation in writing of any claim by the
Internal Revenue Service which, if successful, would require Corporation to make
a Gross-Up Payment (or a Gross-Up Payment in excess of that, if any, initially
determined by Corporation and Employee) within ten (10) days of the receipt of
such claim.  Corporation shall notify Employee in writing at least ten days
prior to the due date of any response required with respect to such claim if it
plans to contest the claim.  If Corporation decides to contest such claim,
Employee shall cooperate fully with Corporation in such action; provided,
however, Corporation shall bear and pay directly or indirectly all costs and
expenses (including additional interest and penalties) incurred in connection
with such action and shall indemnify and hold Employee harmless, on an after-tax
basis, for any Excise Tax or income tax, including interest and penalties with
respect thereto, imposed as a result of Corporation's action.  If, as a result
of Corporation's action with respect to a claim, Employee receives a refund of
any amount paid by Corporation with respect to such claim, Employee shall
promptly pay such refund to Corporation.  If Corporation fails to timely notify
Employee whether it will contest such claim or Corporation determines not to
contest such claim, then Corporation shall immediately pay to Employee the
portion of such claim, if any, which it has not previously paid to Employee.

                             EMPLOYMENT AGREEMENT

     This Employment Agreement (the "Agreement") is entered into this 24th day
of September, 1997, to be effective on the date set forth below, by and between
XPLOR Energy, Inc., a Delaware corporation ("Corporation"), and Craig S. Davis
("Employee").

                                  WITNESSETH:

     WHEREAS, Corporation desires to employ Employee, and Employee desires to
accept such employment;

     WHEREAS, Corporation and Employee desire to agree to the specific terms of
such employment set forth in this Agreement.

     NOW, THEREFORE, in consideration of the recitations stated above and the
mutual terms, covenants and conditions contained herein, Corporation and
Employee agree as follows:

     1.   EMPLOYMENT

          1.1  Employment.  Corporation hereby employs Employee and Employee
hereby accepts such employment, as Vice President, Geophysics, subject to the
supervision and direction of Corporation's President, other Officers of the
Corporation as applicable and its Board of Directors.

          1.2  Term of Employment. The term of employment provided for in this
Agreement shall commence on September 24, 1997("Effective Date"), shall
remain in full force and effect for a period of three years thereafter and shall
terminate on the third anniversary of the Effective Date, unless terminated
sooner as provided in Section 4 hereof. Beginning on the second anniversary of
the Effective Date, and on the last day of each succeeding month following the
second anniversary ("Monthly Renewal Date"), the term of Employee's employment
shall be automatically extended on the terms and condition then in effect for
one (1) additional month such that there shall always be at least one (1) year
remaining on the term of this agreement at all times, unless, at least fifteen
(15) days prior to the second anniversary of the Effective Date or any such
Monthly Renewal Date, either party shall have delivered to the other, written
notice that the term hereof shall not be extended.

     2.   DUTIES

          2.1  Full-time Employment.  Unless otherwise authorized by
Corporation, Employee shall devote substantially all of his business time,
attention and skills to the performance of his duties as Vice President,
Geophysics of Corporation.  During the term of this Agreement, Employee shall
not render services for any other person or entity than Corporation unless
otherwise authorized by Corporation; provided, however, that upon the approval
of Corporation, Employee may serve as a director of other corporations or
entities that engage in other activities to the extent that they do not inhibit
the performance of Employee's duties 


                                      -1-
<PAGE>
 
hereunder, or conflict with the business of the Corporation, its subsidiaries,
or affiliates. The voluntary performance by Employee of any duties assigned to
him which are not of the type provided for herein shall not constitute a waiver
of his rights hereunder or an abrogation, abandonment or termination by him of
this Agreement.

     Employee shall not be restricted from engaging in a business or from
investing his assets in a manner which is non-competitive with Corporation and
its affiliates or subsidiaries and which will not require any significant
services on his part in the operation of the affairs of the companies in which
such investments are made or from engaging in charitable or voluntary activities
to the extent that the total amount of time expended on such business,
investing, charitable or voluntary activities is reasonable, is consistent with
Employee's duties hereunder, and does not conflict with Employee's ability or
time necessary to perform his duties hereunder.

          2.2  Employer-Employee Relationship.  The relationship between
Corporation and Employee is that of an employer and employee.  Corporation shall
have the right to instruct, control, review and, subject to the terms of this
Agreement, modify the nature as requested by Corporation and scope of services,
and manner in which Employee performs such services for Corporation.

     3.   COMPENSATION AND RELATED MATTERS.  Subject to the terms and conditions
hereof, Employee shall receive the following salary and other benefits as full
consideration for the services to be rendered hereunder.

          3.1  Regular Salary. Until such time as the Corporation becomes
subject to the reporting requirements of the Securities Exchange Act of 1934,
Employee shall be paid a salary for all services rendered under this Agreement
at the annual rate of $165,000 per year, payable in accordance with the general
payroll practices of the Corporation in effect from time to time.  In the event
Corporation becomes subject to the reporting requirements of the Securities
Exchange Act of 1934, Employee's annual salary shall be changed to $155,000 per
year.  In either case, the Employee's salary shall be reviewed annually, and may
be increased, but not decreased, from the salary then in effect or the salary
prescribed by this Section 3.1, in Corporation's discretion, as determined by
the Compensation Committee of the Board of Directors.

          3.2  Expenses.  The Employee shall be reimbursed for all reasonable
and necessary business expenses incurred in the performance of service
hereunder, and accounted for in accordance with the policies and procedures
established from time to time by Corporation.  In addition, Employee shall
receive an automobile allowance of $500 per month payable in accordance with the
general payroll practices of the Corporation in effect from time to time.

          3.3  Vacation.  Employee shall be entitled to four (4) weeks paid
vacation during each full 12-month period during the term hereof; provided,
however that in taking such vacation Employee shall give and exercise reasonable
consideration to and for the needs and interests of Corporation. Employee shall
also be entitled to such other vacation time and paid holidays, if any, as shall
from time to time be determined by Corporation.

                                      -2-
<PAGE>
 
          3.4  Employee Benefit Plans.  Employee shall be included in all of the
employee benefit plans existing now or in the future providing pension, thrift,
profit sharing, bonus or similar benefits as they are provided generally to
officers of the Corporation, subject to the terms and conditions of all such
plans.  In addition, Employee shall be eligible to participate in all executive
compensation programs or other perquisites available to other officers of
Corporation, subject to the terms and conditions of such programs.

          3.5  Insurance and Welfare Benefit Plans.  Corporation shall cover
Employee under its group dental, medical and hospitalization plans, shall
provide Employee term life insurance coverage, and will cover Employee under
other insurance and employee welfare benefit plans maintained for its officers
generally.  Corporation shall also use its best efforts to evaluate and provide
disability insurance coverage and life insurance coverage which are payable to
the beneficiary of employee's choice.

          3.6  Place of Performance.  The headquarters for the performance of
Employee's duties shall be located in The Woodlands, Texas, and/or other office
locations of the Corporation within the metropolitan Houston area, but from time
to time Employee shall be required to travel to other locations in the proper
conduct of his responsibilities under this Agreement.  As it is Corporation's
intention to expand the business of Corporation on a national scale, Corporation
may require Employee to spend a reasonable amount of time traveling, as his
duties and the business of Corporation and its affiliates or subsidiaries may
require.

          3.7  Stock Option Awards, Other Awards.  The Board of Directors or its
Compensation Committee, as the case may be, shall consider Employee for the
grant of options to purchase common stock or other awards, as Employee's
performance dictates, no less frequent than annually during the term of this
Agreement under any plan of the Corporation which provides for such stock
options or other awards. Unless modified by the Board of the Directors any
awards granted to Employee pursuant to any other such plans adopted by the
Corporation (the "Incentive Plans") shall be immediately vested in full and
exercisable upon the occurrence of any of the following:  (i) any Change of
Control (as defined herein); (ii) termination of Employee by the Corporation
without just cause (as defined herein); (iii) any substantial or material
diminishment in Employee's reporting responsibilities as designated in this
Agreement; (iv) Employee's death; or (v) at the termination of this agreement
due to Employee's disability as defined in Section 4.2 of this agreement.  Any
agreement for an award under the Incentive Plans granted to Employee shall
reflect the provisions of this Section 3.7.

          3.8  Incentive Bonus.  Beginning in 1998, Employee shall be eligible
to receive a bonus of up to 40% of annual base salary as an annual incentive
bonus subject to the achievement of certain performance goals established by the
Board of Directors as discussed below. The bonus for 1998 shall be paid no later
than the end of January, 1999. The bonus shall be based on attainment of
performance goals to be established no later than the end of the first quarter
of each calendar year, subject to approval of those performance goals by the
Board of Directors, which will provide for at least the following:  (i)
financial targets; (ii) operating targets, and (iii) exploration success
targets.

                                      -3-

     4.   TERMINATION OF AGREEMENT.  This Agreement will continue in effect
until the expiration of the term stated in Section 1 hereof unless sooner
terminated as set forth below.  If such termination occurs, Employee shall
continue to be subject to Section 5 hereof.

          4.1  Death of Employee.  If Employee shall terminate employment due to
death during the term of this Agreement, this Agreement shall terminate and his
spouse, if she is then surviving or if not, his legal representative, shall be
entitled to receive in one lump sum a pro rata share of incentive compensation
under Section 3.8 based on the number of days in the year that elapsed prior to
death and as if all performance goals had been met.

          4.2  Illness or Other Incapacity.  If during the term of this
Agreement, Employee shall fail to perform his duties hereunder as a result of
illness or other incapacity and such illness or incapacity shall continue for a
period of more than three (3) months, Corporation shall have the right to
terminate this Agreement and the employment hereunder as of date to be specified
in a notice of termination, such date to be not less than thirty (30) days after
the mailing by certified mail of such notice.  If Employee's illness or
incapacity shall have ended, and the Employee shall have assumed his duties
hereunder, prior to the date specified in the notice of termination, he shall be
entitled to resume his employment hereunder as if such notice had not been
given.  If such termination occurs, Employee shall continue to be bound by the
covenants contained in Section 5 hereof, but in all other regards, this
Agreement shall terminate as of such termination date, and Corporation shall pay
to Employee or his legal representative (i) compensation provided for in Section
3.1 of this Agreement for the remaining term of this Agreement, but in no event
less than one year, if the Corporation has not provided disability insurance
pursuant to Section 3.5 (ii) a pro rata share of incentive compensation under
Section 3.8 based on the number of days in the year that elapsed prior to such
termination and as if all performance goals had been met, and (iii) such other
benefits, if any, as may be determined by Corporation.
 
          4.3  Termination by Corporation for Cause.  Corporation may terminate
this Agreement and the employment of Employee by service of written notice of
termination to Employee specifying the circumstances and an effective date for
such termination upon the earlier to occur of any of the following events: (i)
Employee willfully misappropriates the property of Corporation or commits any
other act of dishonesty which results in injury to Corporation or reasonably
could result in injury to Corporation; (ii) Employee engages in personal
misconduct which results in material injury to Corporation, or could reasonably
result in material injury to Corporation unless Employee in good faith
reasonably believed that his actions were in the best interest of Corporation,
(iii) Employee is convicted of a felony; or (iv) the Board of Directors had
determined in good faith that Employee has failed to diligently perform his
duties hereunder as specified by Corporation and in a manner consistent with
prudent business practice and such failure continues after Employee has been
given at least ten (10) days written notice of the failure.  In the event this
Agreement is terminated for cause set forth in paragraphs (i) through (iv) above
by the Corporation prior to the conclusion of the term of this Agreement, the
Corporation shall have no further obligation hereunder, except for its payment
of the compensation provided for in Section 3.1 of this Agreement for a period
of three (3) months 

                                      -4-
<PAGE>
 
following such termination, which compensation shall be considered a debt of the
Corporation and shall not be discharged by reason of termination of Employee's
employment.

          4.4  Termination by Corporation for Other than Cause.  In the event
Corporation terminates Employee's employment for any reason other than under
Section 4.3, Employee shall be entitled to a payment from Corporation in an
amount equal to the Termination Payment (as hereinafter defined).  For purposes
of this Agreement, the term "Termination Payment" shall mean an amount equal to
the sum of (i) all base salary that would have been paid to Employee pursuant to
Section 3.1 during the balance of the term of employment provided for in Section
1.2 (but in no event less than twelve (12) months of such base salary) (the
"Salary Portion"), and (ii) subject to the execution by Employee of a waiver and
release of all claims against Corporation, all incentive compensation that would
have been paid to Employee pursuant to Section 3.8 as if all performance goals
had been met during the balance of the term provided for in Section 1.2 (but in
no event less than one such annual incentive bonus) (the "Bonus Portion").  The
Termination Payment shall be paid (i) with respect to the Bonus Portion, in  one
(1) lump sum cash payment within five (5) days after Employee has signed a
release and any applicable revocation period has expired and (ii) with respect
to the Salary Portion, in one (1) lump sum cash payment within five (5) days
after such termination of employment.

          4.5  Termination Following Change of Control.  In the event that a
"Change of Control" (as hereinafter defined) occurs and, within one (1) year
following such Change of Control, Employee's employment is terminated by
Corporation for a reason other than as described in Section 4.3, or he
voluntarily terminates employment due to a substantial diminishment in his job
responsibilities or duties or a material breach by Corporation of any material
provision of this Agreement or any other agreement with Employee which remains
uncorrected for ten (10) days following written notice of such diminishment or
breach by Employee to Corporation, then, in lieu of any payments pursuant to
Sections 4.4 or 4.6 hereof, Employee shall be entitled to a Termination Payment
under terms and conditions applicable pursuant to Section 4.4, provided that the
reference therein to 12 months shall be deemed to be a reference to 24 months
and the reference to one such annual incentive bonus shall be deemed to be a
reference to two such annual incentive bonuses.  A "Change of Control" shall
mean (i) any sale by Corporation of substantially all of its assets or, (ii) the
removal or failure to re-elect R.A. Krenzke as a member of the Board of
Directors for any reason other than resignation, voluntary removal, termination
by Corporation for cause, disability or death, provided the South Coast owners
have the right to a Board seat pursuant to the Acquisition Agreement and Plan of
Organization dated August 19, 1997 or (iii) the acquisition by any "person,"
including a "group" as determined in accordance with Section 13(d)(3) of the
Securities Exchange Act of 1934, of beneficial ownership, directly or
indirectly, of securities of Corporation representing 50% or more of the
combined voting power of Corporation's then outstanding securities; provided,
however, that no Change of Control shall be deemed to occur if beneficial
ownership in Corporation's then outstanding securities is acquired pursuant to
any reorganization of Corporation or recapitalization, spinoff or other
transaction if, after giving effect to such transaction, however structured, at
least 50% of the outstanding voting securities with the ultimate parent entity
corporation are beneficially owned in the aggregate, directly or indirectly
through one or more intermediaries, by the former shareholders of the
Corporation.

          4.6  Termination by Employee for Good Reason.  If Employee's
employment hereunder shall be terminated by Employee due to a substantial
diminishment in Employee's job responsibilities or duties or a material breach
by Corporation of any material provision of this Agreement or any other
agreement with Employee which remains uncorrected for ten (10) days following
written notice of such diminishment or breach by Employee to Corporation, then
Employee shall be entitled to a Termination Payment under terms and conditions
applicable pursuant to Section 4.4.

          4.7  Voluntary Termination by Employee.  Notwithstanding any provision
herein to the contrary, Employee shall have the right to terminate his
employment under this Agreement at any time and for any reason whatsoever.  If
Employee's employment hereunder shall be terminated by Employee for any reason
whatsoever other than the reasons specified in Sections 4.1, 4.2, 4.5 or 4.6,
then, upon such termination, all compensation and all benefits to Employee
hereunder shall terminate contemporaneously with the termination of such
employment. However, in the event Corporation has not become subject to the
reporting requirements of the Securities Exchange Act of 1934 within one (1)
year of the effective date of this Agreement and Employee has remained an
employee of the Corporation for at least one (1) year prior to such termination,
Employee shall be entitled to receive an amount equal to twelve (12) months of
his annual base salary then in effect, which shall be paid in one lump sum
within five (5) days after such time of termination.

          4.8  No Duty to Mitigate Losses.  Employee shall have no duty to find
new employment following the termination of his employment under circumstances
which required Corporation to pay any amount to Employee pursuant to this
Section 4.  Any salary or remuneration received by Employee from a third party
for the providing of personal services (whether by employment or by functioning
as an independent contractor) following the termination of his employment under
circumstances pursuant to which Sections 4.2, 4.4, 4.5, 4.6 or 6.7 apply shall
not reduce Corporation's obligation to make a payment to Employee (or the amount
of such payment) pursuant to the terms of any such Section.

          4.9  Liquidated Damages.  In light of the difficulties in estimating
the damages for an early termination of this Agreement, Corporation and Employee
hereby agree that the payments, if any, to be received by Employee pursuant to
Sections 4.1, 4.2, 4.4, 4.5, 4.6 or 6.7 shall be received by Employee as
liquidated damages.

          4.10 Incentive and Deferred Compensation.  This Agreement governs the
rights and obligations of Employee and Corporation with respect to Employee's
base salary, incentive compensation pursuant to Section 3.8 and certain
perquisites of employment.  Employee's rights and obligations both during the
term of his employment and thereafter with respect to stock options, restricted
stock, incentive and deferred compensation (other than incentive compensation
payable pursuant to Section 3.8), life insurance policies insuring the life of
Employee, and other benefits under the plans and programs maintained by
Corporation shall be governed by the separate agreements, plans and other
documents and instruments governing such matters.

     5.   AGREEMENT RESTRICTING TRADE SECRETS AND COMPETITION.

          5.1  Confidential Information and Trade Secrets.  Employee
acknowledges that he will have access to and that there will be disclosed to him
during the course of this employment, information of a proprietary nature owned
by Corporation, which is of a confidential nature and all of which have great
value to Corporation and which is a substantial basis and foundation upon which
Corporation's business is predicated.  Employee acknowledges that except for his
employment and the duties assigned to him which he will be fulfilling, that he
would not otherwise have access to the foregoing information.  Employee agrees
that any and all confidential knowledge or information which may be obtained by
him in the course of his employment will be held inviolate by him and that he
will conceal the same from any and all other persons, including, but not limited
to, competitors of Corporation, and that he will not impart any such knowledge
acquired by him as an employee of Corporation to anyone whomsoever either during
this employment or after his employment by Corporation has terminated, except to
the extent (i) such disclosure is required by law, (ii) such information is
otherwise made public by Corporation (other than by Employee in violation
thereof), or (iii) such disclosure is made in the normal course of business and
is consistent with Corporation's interests.

     Employee agrees that upon termination of his employment hereunder he will
immediately surrender and turn over to Corporation all books, records, forms,
data, electric logs, geological maps, scout cards, seismic tapes and all papers
and writings relating to the business of Corporation and other information which
reflects or reveals Corporation's confidential or trade secret information
protected by this Section, and all other property belonging to Corporation, it
being understood and agreed that the same are the sole property of Corporation
and that Employee will not make any copies thereof; provided, however, the
parties agree that Employee's personnel files and any logs, records, and maps
which were Employee's property prior to the Effective Date shall remain
Employee's property.  For purposes of this Section 5, the term "Corporation"
shall include Corporation as herein defined and any of its subsidiaries,
affiliates or parent organizations.

          5.2  Noncompetition Agreement.  Except as provided in Section 2.1, for
so long as this Agreement is in effect and for a period of six (6) months after
termination of his employment, Employee will not, without Corporation's written
permission, directly or indirectly, own, manage, operate, control, be employed
by, participate in or be connected in any manner with the ownership, management,
operation, or control of any business which is in direct competition with
Corporation, specifically with respect to the geologic prospects or any planned
or completed acquisitions (of stock, equity or assets) in or through which
Corporation does explore, develop or produce oil and gas or has current plans to
explore, develop or produce oil and gas. Corporation shall within ten (10) days
of Employee's termination of employment with the Corporation provide Employee
with a complete list of any properties, prospects, acquisitions, data
acquisitions, corporate transactions or other financial or business arrangements
contemplated by the Corporation to which the preceding sentence applies.
Employee must approve in writing, and no such approval can be reasonably
withheld, to the listing provided by the Corporation.  Any disputes which cannot
be settled will be handled as provided in Section 6.10 of this Agreement. For so
long as this Agreement is in effect and for a period of six (6) months after

                                      -7-
<PAGE>
 
termination of his employment, Employee shall refrain from contacting or
encouraging any third party to contact any individual who is employed by
Corporation or its affiliates for the purpose of recruiting or placing that
individual with any other employer.

          5.3  Injunctive Relief.  Employee specifically acknowledges and agrees
that the remedy at law for any breach of the provisions of Sections 5.1 or 5.2
will be inadequate and that Corporation shall be entitled to temporary and
permanent injunctive relief without the necessity of proving actual damage.

          5.4  Reformation.  In the event that the provisions of this Section 5
should ever be deemed to exceed the time or geographic limitations permitted by
applicable law, then such provision shall be deemed reformed to the maximum time
or geographic limitations permitted by applicable law.

     6.   GENERAL.

          6.1  Indemnity and Directors' & Officers' Liability Insurance
Coverage.  Corporation agrees to indemnify and defend Employee, at Corporation's
sole expense, in any matters arising from Employee's performance of his duties
as an employee, officer or director of Corporation or any of Corporation's
subsidiaries or affiliates to the fullest extent permitted by law.  The
Corporation will take reasonable steps to obtain Directors' and Officers'
liability insurance prior to becoming subject to the reporting requirements of
the Securities Exchange Act of 1934.

          6.2  Headings.  Section headings are included solely for convenience
and should not be used in the interpretation of this Agreement.

          6.3  Severability.  In the event any one or more of the provisions
contained in the Agreement shall, for any reason, be held to be invalid, illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability
shall not effect any other provisions of this Agreement, and this Agreement
shall be construed in all respects as if such invalid or unenforceable
provisions were omitted.

          6.4  Notices.  Any notice, demand and all other communications
required or permitted to be given under this Agreement shall be in writing and
shall have been deemed duly given when delivered or (unless otherwise specified
herein) three (3) business days after mailed by United States registered mail,
return receipt requested, postage prepaid, to the address set forth on the
signature page hereof, or to such other address as any party may have furnished
to the other in writing in accordance herewith, except that notices of change of
address shall be effective only upon receipt.

          6.5  Waiver of Breach; Expenses.  The waiver by Employee or
Corporation of a breach of any provision of this Agreement shall not operate or
be construed as a waiver of any subsequent breach.  In any action brought by any
party hereto pursuant to Section 6.10 of the 

                                      -8-
<PAGE>
 
Agreement, the prevailing party shall be entitled to collect such party's
reasonable attorney's fees, court costs and expenses in such action.

          6.6  Binding Effect; Assignment.  The respective rights and
obligations of Corporation and Employee under the Agreement shall inure to the
benefit of and shall be binding upon Corporation and the respective successors
and assigns of Corporation.  This Agreement shall not be assignable by Employee.
As used herein, the term "successors and assigns" shall include any corporation
or corporations which acquire all or substantially all of the assets and
businesses of Corporation whether by purchase, merger, consolidation or
otherwise.  The parties hereto presently contemplate that Corporation will enter
into certain transactions resulting in a reorganization of Corporation and in
connection therewith this Agreement shall automatically be assigned to the
parent of Corporation and all references herein to Corporation shall thereafter
be deemed to be references to such parent entity.

          6.7 Certain Additional Payments by Company. Notwithstanding anything
to the contrary in this Agreement, in the event that any payment or distribution
by Corporation to or for the benefit of Employee, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise (a "Payment") would be subject to the excise tax imposed by Section
4999 of the Internal Revenue Code of 1986, as amended, or any interest or
penalties with respect to such excise tax (such excise tax, together with any
such interest or penalties, are herein collectively referred to as the "Excise
Tax"), Corporation shall pay to Employee an additional payment (a "Gross-up
Payment") in an amount such that after payment by employee of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax imposed on any Gross-up Payment, Employee retains an
amount of the Gross-up Payment equal to the Excise Tax imposed upon the
Payments. Corporation and Employee shall make an initial determination as to
whether a Gross-Up Payment is required and the amount of any such Gross-Up
Payment. Employee shall notify Corporation in writing of any claim by the
Internal Revenue Service which, if successful, would require Corporation to make
a Gross-Up Payment (or a Gross-Up Payment in excess of that, if any, initially
determined by Corporation and Employee) within ten (10) days of the receipt of
such claim. Corporation shall notify Employee in writing at least ten days prior
to the due date of any response required with respect to such claim if it plans
to contest the claim. If Corporation decides to contest such claim, Employee
shall cooperate fully with Corporation in such action; provided, however,
Corporation shall bear and pay directly or indirectly all costs and expenses
(including additional interest and penalties) incurred in connection with such
action and shall indemnify and hold Employee harmless, on an after-tax basis,
for any Excise Tax or income tax, including interest and penalties with respect
thereto, imposed as a result of Corporation's action. If, as a result of
Corporation's action with respect to a claim, Employee receives a refund of any
amount paid by Corporation with respect to such claim, Employee shall promptly
pay such refund to Corporation. If Corporation fails to timely notify Employee
whether it will contest such claim or Corporation determines not to contest such
claim, then Corporation shall immediately pay to Employee the portion of such
claim, if any, which it has not previously paid to Employee.

          6.8  Entire Agreement Counterparts.  Except as provided in (i) the
benefits, plans, and programs, if any, referenced in Sections 3.4, 3.5, 3.7 and
3.8 hereof and (ii) any 

                                      -9-
<PAGE>
 
signed written agreements contemporaneously or hereafter executed by Corporation
and Employee, this Agreement contains the entire agreement of the parties
hereto, notwithstanding any oral representation of the parties to the contrary.
This Agreement supersedes as of the Effective Date all agreements, oral or in
writing, and other arrangements between the parties with respect to all matters
related to the subject matter hereof. This Agreement may be executed in multiple
counterparts, all of which shall constitute one Agreement, but both parties must
execute and deliver one signed counterpart before this Agreement is effective.

          6.9  Applicable Law.  The execution, performance and enforcement of
this Agreement shall be governed by and construed in accordance with the
internal laws of the State of Texas without giving effect to its conflict of
laws provision.

          6.10 Claims; Arbitration.

          (a) All claims by Employee for compensation and benefits under this
Agreement shall be directed to and determined by the Board of Directors and
shall be in writing.  Any denial by the Board of Directors of a claim for
benefits under this Agreement shall be delivered to Employee in writing and
shall set forth the specific reasons for the denial and specific provisions of
this Agreement relied upon.  The Board of Directors shall afford a reasonable
opportunity to Employee for a review of a decision denying a claim and shall
further allow Employee to appeal to the Board of Directors a decision of the
Board of Directors within 60 days after notification by the Board of Directors
that Employee's claim has been denied.

          (b) To the extent permitted by applicable law, any further dispute or
controversy arising under or in connection with this Agreement shall be settled
exclusively by arbitration in Houston, Texas, in accordance with the rules of
the American Arbitration Association then in effect.  The agreement set forth
herein to arbitrate shall be specifically enforceable under the prevailing
arbitration law.

          (c) Notice of the demand for arbitration shall be filed in writing
with the other party to this Agreement and with the American Arbitration
Association.  The demand for arbitration shall be made within a reasonable time
after the claim, dispute or other matter in question has arisen, and in no event
shall it be made after the date when institution of legal or equitable
proceedings based on such claim, dispute or other matter in question would be
barred by the applicable statute of limitations.

          (d) The award rendered by the arbitrator shall be final and judgment
may be entered upon it in accordance with applicable law in any court having
jurisdiction thereof.

          (e) Unless otherwise agreed in writing, Corporation shall continue to
make payments and provide benefits in accordance with this Agreement, and
Employee shall continue to perform his obligations hereunder during any
arbitration proceedings.
