   This summary highlights information contained elsewhere in this prospectus.
This summary is not complete and does not contain all of the information that

About 3TEC

   We are engaged in the acquisition, development, production and exploration
of oil and natural gas reserves. Our properties are concentrated in East Texas
and the Gulf Coast region, both onshore and in the shallow waters of the Gulf
of Mexico. We also own significant properties in the Permian and San Juan
basins and in the Mid-Continent region. Our management and technical staff have
substantial experience in each of these areas. As of December 31, 1999, on a
pro forma basis including the recent acquisition of Magellan Exploration LLC
("Magellan") and the pending acquisition of properties in East Texas operated
by C.W. Resources, Inc. (the "CWR Properties"), discussed below, we had
estimated total net proved reserves of 309 Bcfe, of which approximately 76%
were natural gas and approximately 70% were classified as proved developed,
with an estimated PV-10 value of $293.6 million. As of March 31, 2000, on a pro
forma basis including the CWR Properties, our net daily production was
approximately 51.6 Mmcf of natural gas and 3.4 MBbls of oil or 72.0 Mmcfe.

   We have increased our reserves and production principally through
acquisitions. We focus on properties that have a substantial proved reserve
component and which management believes have additional exploitation
opportunities. Through the recently completed acquisition of Magellan, we have
also acquired a number of drilling prospects covered by an extensive 3-D
seismic database that we believe have exploration potential. We have assembled
an experienced management team and technical staff with expertise in property
acquisitions and development, reservoir engineering, exploration and financial
management. After this offering, we believe that our cash flow from operations
and our financial resources will provide us with the ability to fully develop
our current properties, to finance our current exploration projects and to
pursue new acquisition opportunities.

   As further discussed below, in August 1999, W/E Energy Company L.L.C. ("W/E
LLC") purchased a controlling interest in us, and Floyd C. Wilson was named our
Chairman and Chief Executive Officer. Since that time, we have acquired net
proved reserves of 192.1 Bcfe with an associated PV-10 value of $186.2 million
and have entered into an agreement to purchase the CWR Properties with net
proved reserves of 63.9 Bcfe and an estimated PV-10 value of $54.9 million, in
both cases calculated as of December 31, 1999. In addition, we have raised or
issued $23.0 million of private equity and equity linked financing and have
entered into a new $250 million revolving credit facility.

Our Strategy

   Our business strategy is focused on the following:

  . Pursuit of Strategic Acquisitions. We continually review opportunities to
    acquire producing properties, leasehold acreage and drilling prospects.
    We seek to acquire operational control of properties that we believe have
    significant exploitation and exploration potential. We are especially
    focused on increasing our holdings in fields and basins in which we
    already own an interest.

  . Further Development of Existing Properties. We intend to further develop
    our properties that have proved reserves. We seek to add proved reserves
    and increase production through the use of advanced technologies,
    including detailed technical analysis of our properties, and by drilling
    infill locations and selectively recompleting existing wells. We also
    plan to drill step-out wells to expand known field limits. We intend to
    enhance the efficiency and quality control of these activities by
    operating the majority of our properties.

                                       4
<PAGE>


  . Growth Through Exploration. We conduct an active technology-driven
    exploration program that is designed to complement our property
    acquisition and development drilling efforts with moderate to high risk
    exploration projects that have greater reserve potential. We generate
    exploration prospects through the analysis of geological and geophysical
    data and the interpretation of 3-D seismic data. We intend to manage our
    exploration expenditures through the optimal scheduling of our drilling
    program and by selectively reducing our participation in certain
    exploratory prospects through sales of interests to industry partners.

  . Rationalization of Property Portfolio. We intend to actively pursue
    opportunities to reduce and control operating costs of our existing
    properties and properties we may acquire in the future through the
    consolidation of overlapping operations, the sale of marginal properties
    and by increasing the number of fields we operate as a percentage of our
    total properties.

  . Maintenance of Financial Flexibility. We intend to maintain substantial
    unused borrowing capacity under our bank credit facility by periodically
    refinancing our bank debt in the capital markets when conditions are
    favorable. We believe our expanded base of internally generated cash flow
    and other financial resources, including our existing financial partners,
    provide us with the financial flexibility to pursue additional
    acquisitions of producing properties and leasehold acreage and to develop
    our project inventory in an optimal fashion.

Recent Developments

   Set forth below is a summary of the transactions we have completed or that
are currently pending following the acquisition by W/E LLC of a controlling
interest in us:

</TABLE>

  . Acquisition of Control by W/E LLC. In August 1999, W/E LLC, formerly
    known as 3TEC Energy Company L.L.C., which is owned by affiliates of
    EnCap Investments L.L.C. ("EnCap") and Floyd C. Wilson, purchased a
    controlling interest in us for approximately $20.5 million in cash and
    $875,000 in producing properties. As of March 31, 2000, W/E LLC owned
    approximately 25% of our outstanding common stock, or approximately 45%
    assuming the exercise and conversion of all securities purchased by them
    in August 1999. After giving effect to this offering, W/E LLC will own
    approximately 13% of our outstanding common stock, or approximately 26%
    assuming the exercise and conversion of all securities purchased by them
    in August 1999. Concurrent with the investment by W/E LLC, Mr. Wilson was
    named our Chairman and Chief Executive Officer.

  . Acquisition of Floyd Oil Properties. In November 1999, we completed the
    acquisition of properties and interests managed by Floyd Oil Company (the
    "Floyd Oil Properties") for $90.2 million, consisting of $86.8 million in
    cash and 503,426 shares of our common stock. The majority of these
    properties are located in Texas and Louisiana and, as of December 31,
    1999, had estimated proved reserves of 165.5 Bcfe with an associated PV-
    10 value of $146.1 million. Additionally, 76% of the acquired reserves
    are natural gas and 77% are classified as proved developed. We operate
    approximately 53% of these properties on a PV-10 value basis and, as of
    December 31, 1999, net daily

                                       5
<PAGE>

    production was approximately 41.6 Mmcfe. We plan to actively exploit
    these properties and have budgeted approximately $5 million for
    development drilling and exploitation activity in 2000. Floyd Oil Company
    is not affiliated with Floyd C. Wilson.

  . Credit Facility. Concurrently with our acquisition of the Floyd Oil
    Properties, we entered into a new $250 million credit facility with Bank
    One, Texas, N.A., as agent, and Union Bank of California, N.A., Wells
    Fargo Bank, CIBC, Inc. and The Bank of Nova Scotia as participating
    lenders. Our borrowing base, which is redetermined semi-annually, has
    been initially set at $95.0 million with $83.5 million outstanding as of
    March 31, 2000. In connection with the pending CWR Properties
    acquisition, we have begun negotiations with the lenders participating in
    our credit facility to increase the availability under our borrowing base
    to an amount which would enable us to borrow substantially all of the
    purchase price. The negotiations are ongoing and the lenders have
    indicated their preliminary willingness to accommodate this increase. The
    net proceeds of this offering will be used primarily to repay
    indebtedness outstanding under this facility.

  . Acquisition of Magellan. On February 3, 2000, we completed the
    acquisition of Magellan from certain affiliates of EnCap and other third
    parties for consideration of approximately $18.6 million consisting of
    (a) 1,085,934 shares of common stock, (b) four year warrants to purchase
    up to 333,333 shares of common stock at $30.00 per share, (c) 617,008
    shares of 5% Series D Convertible Preferred Stock which have a redemption
    value of $24.00 per share and are each convertible into one share of
    common stock and (d) the assignment of a performance based "back-in"
    working interest of 5% of Magellan's interest in 12 exploration
    prospects. Magellan's properties are located both onshore and in the
    shallow waters of south Louisiana and consist of 20,243 gross (10,748
    net) acres in three prospective areas. As of December 31, 1999, Ryder
    Scott Company ("Ryder Scott"), estimated that Magellan's net proved
    reserves were 26.6 Bcfe with an associated PV-10 value of $40.1 million.
    These proved reserves are approximately 66% natural gas and 81% are
    classified as proved undeveloped. Magellan operates approximately 80% of
    its properties on a PV-10 value basis. In addition to the proved
    reserves, the Magellan properties contain several exploratory drilling
    locations that have been identified using 3-D seismic data.

  . Pending Acquisition of CWR Properties. On April 14, 2000, we entered into
    a definitive agreement to acquire the CWR Properties for cash
    consideration of approximately $52 million, assuming we do not acquire
    operations of these properties. We paid a deposit of $5.2 million at the
    time we executed the definitive agreement. The purchase of the CWR
    Properties will be financed under our existing credit facility, which we
    propose to modify prior to closing this acquisition. The closing of the
    CWR Properties is contingent upon satisfaction of customary closing
    conditions and is expected to close on or before May 31, 2000. This
    offering is contingent upon the closing of the purchase of the CWR
    Properties. The effective date of the acquisition will be January 1,
    2000.

    The CWR Properties are located in Upshur and Gregg Counties, Texas, in
    strategic proximity to our core East Texas properties. The CWR Properties
    encompass approximately 36,000 gross acres (8,900 net acres). As of
    December 31, 1999, Ryder Scott estimated that the net proved reserves of
    the CWR Properties were 63.9 Bcfe with an associated PV-10 value of $54.9
    million. The CWR Properties produce from the Cotton Valley formation and
    the reserves are approximately 92% natural gas and 50% are classified as
    proved developed. As of March 31, 2000, net daily production from the CWR

(b) EBITDAX represents earnings before interest expense, income taxes,

    charges. We believe that EBITDAX may provide additional information about
    our ability to meet our future requirements for debt service, capital
    expenditures and working capital. EBITDAX is a financial measure commonly
    used in the oil and gas industry and should not be considered in isolation
    or as a substitute for net income, operating income, cash flows from
    operating activities or any other measure of financial performance
    presented in accordance with generally accepted accounting principles or as
    a measure of a company's profitability or liquidity. Because EBITDAX
    excludes some, but not all, items that affect net income and this measure
    may vary among companies, the EBITDAX data presented above may not be
    comparable to similarly titled measures of other companies.
(c) The "Pro Forma As Adjusted" Balance Sheet Data:
  . assumes the sale of 6,250,000 shares of our common stock in this offering

  . gives effect to the application of the estimated net proceeds from the
    sale of common stock in this offering to repay a portion of our debt;

  . gives effect to the acquisition of Magellan and the related equity
    transactions; and

  . gives effect to the completion of the pending acquisition of the CWR
    Properties and the related financing transactions.

                          Summary Reserve Information

   The table below presents our summary historical and pro forma reserve
information as of December 31, 1999. Estimates of proved reserves are based on
the December 31, 1999 reserve report prepared by Ryder Scott, our independent
petroleum engineering consultants. The pro forma reserve information gives
effect to the acquisition of Magellan and the CWR Properties as if each had
been acquired on December 31, 1999. For additional information relating to our
oil and natural gas reserves, please read "Business and Properties--Description
of Our Properties," note 15 of the notes to our December 31, 1999, consolidated
financial statements, note 6 of the notes to the Floyd Oil Properties September
30, 1999, statements of revenues and direct operating expenses and note 6 of
the notes to the CWR Properties December 31, 1999 statements of revenues and
direct operating expenses.

   As of December 31, 1999, on a pro forma basis including Magellan and the CWR
Properties, our PV-10 value was $293.6 million. For purposes of this
calculation, NYMEX prices of $2.33 per Mmbtu of natural gas and $25.60 per
barrel of oil were used. These NYMEX prices were then adjusted for volumes
subject to long-term contracts and financial hedges and all applicable basis
and quality differentials. After taking into account such adjustments, the
weighted average actual prices used to calculate our pro forma PV-10 value were
$2.30 per Mcf for natural gas and $24.02 per barrel for oil.

                                  RISK FACTORS

   Investing in our common stock will provide you with an equity ownership in
3TEC Energy Corporation. As one of our stockholders, you will be subject to
various risks inherent in our business. The trading price of your shares will
be affected by the performance of our business relative to, among other things,
competition, market conditions and general economic and industry conditions.
The value of your investment may decrease, resulting in a loss. You should
carefully consider the following factors as well as other information contained
in this prospectus before deciding to invest in shares of our common stock.
This prospectus contains forward-looking statements. Our actual results may
differ materially from those projected in the forward-looking statements as a
result of any number of factors, including the risk factors set forth below.

Oil and natural gas prices are volatile, and low prices have in the past and
could in the future have a material adverse impact on our business.

   Our revenues, profitability and future growth and the carrying value of our
properties depend substantially on prevailing oil and natural gas prices.
Prices also affect the amount of cash flow available for capital expenditures
and our ability to borrow and raise additional capital. The amount we will be
able to borrow under our credit facility will be subject to periodic
redetermination based in part on changing expectations of future prices. Lower
prices may also reduce the amount of oil and gas that we can economically
produce.

   Historically, the markets for oil and natural gas have been volatile, and
they are likely to continue to be volatile in the future. For example, oil and
natural gas prices declined significantly in late 1997 and 1998. These declines
had a significant negative impact on our financial results for 1997, 1998 and
the first two quarters of 1999, contributing to our losses for those periods.
Among the factors that can cause volatility are:

  . the domestic and foreign supply of oil and natural gas;

  . the ability of members of the Organization of Petroleum Exporting
    Countries to agree upon and maintain oil prices and production levels;

  . political instability or armed conflict in oil or natural gas producing
    regions;

  . the level of consumer product demand;

  . weather conditions;

  . the price and availability of alternative fuels;

  . the price of foreign imports; and

  . worldwide economic conditions.

   These external factors and the volatile nature of the energy markets make it
difficult to estimate future prices of oil and natural gas.

We may not successfully integrate the operations of the properties we have
acquired or may acquire or achieve the benefits we are seeking.

   Our success will partially depend upon the integration of the operations and
selected personnel relating to the Floyd Oil Properties, the acquisition of
Magellan and the pending acquisition of the CWR Properties. Our management team
does not have experience with the combined activities of 3TEC, the Floyd Oil
Properties, Magellan and the CWR Properties. In addition, our new management
team, including personnel formerly with Magellan and Floyd Oil Company, has not
previously worked together as a single team and thus is subject to personnel
and other risks experienced by newly combined operations. We may not be able to
integrate these operations without loss of important employees, loss of
revenues, increases in operating or other costs, or other difficulties. In
addition, we may not be able to realize the operating efficiencies and other
benefits sought from our acquisitions.

We may not be able to replace production with new reserves through our drilling
or acquisition activities.

   In general, the volume of production from oil and natural gas properties
declines as reserves are depleted. Our reserves will decline as they are
produced unless we acquire properties with proved reserves or conduct
successful development and exploration activities. Our future oil and natural
gas production is highly dependent upon our level of success in finding or
acquiring additional reserves. However, we cannot assure you that our future
acquisition, development and exploration activities will result in additional
proved reserves or that we will be able to drill productive wells at acceptable
costs.

   Our recent growth is due largely to acquisitions of producing properties.
The successful acquisition of producing properties requires an assessment of a
number of factors. These factors include recoverable reserves, future oil and
natural gas prices, operating costs and potential environmental and other
liabilities, title issues and other factors. Such assessments are inexact and
their accuracy is inherently uncertain. In connection with such assessments, we
perform a review of the subject properties that we believe is generally
consistent with industry practices. However, such a review will not reveal all
existing or potential problems. In addition, the review will not permit a buyer
to become sufficiently familiar with the properties to fully assess their
deficiencies and capabilities. Although the increased availability of
properties has caused a decrease in the prices paid for these properties, we
cannot assure you that we will be able to acquire properties at acceptable
prices because the competition for producing oil and natural gas properties is
intense and many of our competitors have financial and other resources which
are substantially greater than those available to us.

Our bank lenders can limit our borrowing capabilities, which may materially
impact our operations.

   As of March 31, 2000, after giving pro forma effect to the application of
the estimated net proceeds of this offering and the acquisition of the CWR
Properties, our long-term bank debt was $89.5 million. At March 31, 2000, our
borrowing base was $95.0 million. In connection with the pending acquisition of
the CWR Properties, we have begun negotiations with the lenders participating
in our credit facility to increase the amount of availability under our
borrowing base. The lenders have indicated their preliminary willingness to
accommodate this increase. The borrowing base limitation under our credit
facility is semi-annually redetermined. Redeterminations are based upon a
number of factors, including commodity prices and reserve levels. The next
redetermination date is May 1, 2000. Upon a redetermination, we could be forced
to repay a portion of our bank debt. We may not have sufficient funds to make
such repayments, which could result in a default under the terms of the loan
agreement and an acceleration of the loan. We intend to finance our
development, acquisition and exploration activities with cash flow from
operations, bank borrowings and other financing activities. In addition, we may
significantly alter our capitalization in order to make future acquisitions or
develop our properties. These changes in capitalization may significantly
increase our level of debt. We may also be able to incur substantial additional
indebtedness in the future. If we incur additional debt for these or other
purposes, the related risks that we now face could intensify. A higher level of
debt also increases the risk that we may default on our debt obligations. Our
ability to meet our debt obligations and to reduce our level of debt depends on
our future performance. General economic conditions and financial, business and
other factors affect our operations and our future performance. Many of these
factors are beyond our control. Our level of debt affects our operations in
several important ways, including the following:

  . a portion of our cash flow from operations is used to pay interest on
    borrowings;

  . the covenants contained in the agreements governing our debt limit our
    ability to borrow additional funds, pay dividends, dispose of assets or
    issue shares of preferred stock and otherwise may affect our flexibility
    in planning for, and reacting to, changes in business conditions;

  . a high level of debt may impair our ability to obtain additional
    financing in the future for working capital, capital expenditures,
    acquisitions, general corporate or other purposes;

  . a leveraged financial position would make us more vulnerable to economic
    downturns and could limit our ability to withstand competitive pressures;
    and

  . any debt that we incur under our credit facility will be at variable
    rates which makes us vulnerable to increases in interest rates.

                                       12
<PAGE>

We have incurred losses from operations in the past, and our failure to achieve
or sustain profitability in the future could adversely affect the market price
of our common stock.

   We incurred net losses of $6.7 million in 1998 and $4.0 million in 1999. On
a pro forma basis, giving effect to the acquisition of the Floyd Oil
Properties, the CWR Properties and this offering, we would have earned a profit
of $5.0 million in 1999, but the pro forma results may not be indicative of
actual operating results had we acquired the Floyd Oil Properties and the CWR
Properties at January 1, 1999. We cannot assure you that we will achieve or
sustain profitability in the future. Our failure to achieve or sustain
profitability in the future could adversely affect the market price of our
common stock.

Prices of our common stock may be volatile.

   The market price of our common stock may be subject to significant
fluctuations in response to events beyond our control. Normal fluctuations in
the prices of our stock may be increased by our trading volumes, which have
been historically low. Our trading volumes may be further reduced by the 1-for-
3 reverse split of our common stock effected on January 18, 2000. There can be
no assurance that the market price of our common stock will not decline below
the price at which shares are sold in this offering.

Our ability to finance our business activities will require us to generate
substantial cash flow.

   Our business activities require substantial capital. We have budgeted total
capital expenditures for 2000 of approximately $20 million, including an
estimated $3.4 million with respect to the CWR Properties. We intend to finance
our capital expenditures in the future through cash flow from operations, the
incurrence of additional indebtedness and/or the issuance of additional equity
securities. We cannot be sure that our business will continue to generate cash
flow at or above current levels. Future cash flows and the availability of
financing will be subject to a number of variables, such as:

  . the level of production from existing wells;

  . prices of oil and natural gas;

  . our results in locating and producing new reserves; and

  . general economic, financial, competitive, legislative, regulatory and
    other factors beyond our control.

   If we are unable to generate sufficient cash flow from operations to service
our debt, we may have to obtain additional financing. We cannot be sure that
any additional financing will be available to us on acceptable terms. Issuing
equity securities to satisfy our financing requirements could cause substantial
dilution to our existing stockholders. The level of our debt financing could
also materially affect our operations. See "Our level of borrowings may
materially affect our operations."

   If our revenues were to decrease due to lower oil and natural gas prices,
decreased production or other reasons, and if we could not obtain capital
through our credit facility or otherwise, our ability to execute our
development and acquisition plans, replace our reserves or maintain production
levels could be greatly limited.

Drilling wells is speculative, often involves significant costs and may not
result in additions to our production or reserves.

   Developing and exploring for oil and natural gas reserves involves a high
degree of operating and financial risk. The budgeted costs of drilling,
completing and operating wells are often exceeded and can increase
significantly when drilling costs rise due to a tightening in the supply of
various types of oilfield equipment and related services. Drilling may be
unsuccessful for many reasons, including title problems, weather, cost
overruns, equipment shortages and mechanical difficulties. Moreover, the
successful drilling of an oil or natural gas well does not ensure a profit on
investment. Exploratory wells bear a much greater risk of loss than development
wells. A variety of factors, both geological and market-related, can cause a
well to become

                                       13
<PAGE>

uneconomical or only marginally economic. In addition to their cost,
unsuccessful wells can hurt our efforts to replace reserves.

We do not insure against all potential losses and could be seriously harmed by
unexpected liabilities.

   Exploration for and production of oil and natural gas can be hazardous,
involving natural disasters and other unforeseen occurrences such as blowouts,
cratering, fires and loss of well control, which can damage or destroy wells or
production facilities, injure or kill people, and damage property and the
environment. Because third party drilling contractors are used to drill our
wells, we may not realize the full benefit of workmen's compensation laws in
dealing with their employees. We maintain insurance against many potential
losses and liabilities arising from our operations in accordance with customary
industry practices and in amounts that we believe to be prudent. However, our
insurance does not protect us against all operational risks.

Estimates of oil and natural gas reserves are uncertain and inherently
imprecise and any material inaccuracies in these reserve estimates will
materially affect the quantities and PV-10 value of our reserves.

   This prospectus contains estimates of our proved oil and natural gas
reserves and the estimated future net revenues from such reserves. These
estimates are based upon various assumptions, including assumptions required by
the Securities and Exchange Commission relating to oil and natural gas prices,
drilling and operating expenses, capital expenditures, taxes and availability
of funds. The process of estimating oil and natural gas reserves is complex.
This process requires significant decisions and assumptions in the evaluation
of available geological, geophysical, engineering and economic data for each
reservoir. Therefore, these estimates are inherently imprecise.

   Actual future production, oil and natural gas prices, revenues, taxes,
development expenditures, operating expenses and quantities of recoverable oil
and natural gas reserves will most likely vary from those estimated. Any
significant variance could materially affect the estimated quantities and PV-10
value of reserves set forth in this prospectus and the information incorporated
by reference. Our properties may also be susceptible to hydrocarbon drainage
from production by other operators on adjacent properties. In addition, we may
adjust estimates of proved reserves to reflect production history, results of
exploration and development, prevailing oil and natural gas prices and other
factors, many of which are beyond our control. Actual production, revenues,
taxes, development expenditures and operating expenses with respect to our
reserves will likely vary from the estimates used. These variances may be
material.

   At December 31, 1999, on a pro forma basis for the acquisition of Magellan
and the pending acquisition of the CWR Properties, approximately 30% of our
estimated proved reserves were undeveloped. The percentage of proved
undeveloped properties were increased as a result of the addition of the
Magellan properties. Undeveloped reserves, by their nature, are less certain
than developed reserves. Recovery of undeveloped reserves requires significant
capital expenditures and successful drilling operations. The reserve data
assumes that we will make significant capital expenditures to develop our
reserves. Although we have prepared estimates of our oil and natural gas
reserves and the costs associated with these reserves in accordance with
industry standards, we cannot assure you that the estimated costs are accurate,
that development will occur as scheduled or that the actual results will be as
estimated.

   In addition, you should not construe PV-10 value as the current market value
of the estimated oil and natural gas reserves attributable to our properties.
We have based the estimated discounted future net cash flows from proved
reserves on prices and costs as of the date of the estimate, in accordance with
applicable regulations, whereas actual future prices and costs may be
materially higher or lower. Many factors will affect actual future net cash
flow, including:

  . prices for oil and natural gas;

  . the amount and timing of actual production;

                                       14
<PAGE>

  . supply and demand for oil and natural gas;

  . curtailments or increases in consumption by oil and natural gas
    purchasers; and

  . changes in governmental regulations or taxation.

   The timing of the production of oil and natural gas properties and of the
related expenses affect the timing of actual future net cash flow from proved
reserves and, thus, their actual PV-10 value. In addition, the 10% discount
factor, which we are required to calculate PV-10 value for reporting purposes,
is not necessarily the most appropriate discount factor given actual interest
rates and risks to which our business or the oil and natural gas industry in
general are subject.

We cannot control the activities on properties we do not operate.

   Other companies operate some of the properties in which we have an interest.
As a result, we have a limited ability to exercise influence over operations
for these properties or their associated costs. The success and timing of our
drilling and development activities on properties operated by others therefore
depend upon a number of factors outside of our control, including:

  . timing and amount of capital expenditures;

  . the operator's expertise and financial resources;

  . approval of other participants in drilling wells; and

  . use of technology.

A small number of existing stockholders control our company, which could limit
your ability to influence the outcome of stockholder votes.

   W/E LLC, an affiliate of EnCap and Floyd C. Wilson, our Chairman and Chief
Executive Officer, Kaiser-Francis Oil Company, C. J. Lett, III, Weskids, L.P.,
Alvin V. Shoemaker and EnCap and its affiliates collectively own approximately
69% of our outstanding common stock as of March 31, 2000, and would own
approximately 79% of our then outstanding common stock as of March 31, 2000, if
all convertible subordinated notes and related warrants owned by them are
converted and exercised. W/E LLC will own approximately 13% of our common stock
outstanding after this offering, assuming that the over-allotment option is not
exercised by the underwriters, and would own approximately 26% of our then
outstanding common stock, if the convertible subordinated notes and related
warrants owned by them were converted and exercised. These stockholders have
entered into an agreement pursuant to which they have agreed to vote all their
shares to elect three members of the board of directors designated by W/E LLC
and two members of the board of directors designated collectively by Kaiser-
Francis Oil Company, C.J. Lett III, Weskids, L.P. and Alvin V. Shoemaker. As a
result, these entities will have a significant voice in the outcome of
stockholder votes, including votes concerning the election of directors, the
adoption or amendment of provisions in our charter or bylaws and the approval
of mergers and other significant corporate transactions.

Competition in our industry is intense, and we are smaller and have a more
limited operating history than many of our competitors.

   We compete with major integrated oil and natural gas companies and
independent oil and natural gas companies in all areas of operation. In
particular, we compete for property acquisitions and for the equipment and
labor required to operate and develop these properties. Most of our competitors
have substantially greater financial and other resources than we have. In
addition, larger competitors may be able to absorb the burden of any changes in
federal, state and local laws and regulations more easily than we can, which
would adversely affect our competitive position. These competitors may be able
to pay more for exploratory prospects and may be able to define, evaluate, bid
for and purchase a greater number of properties and prospects than we can. Our
ability to explore for oil and natural gas prospects and to acquire additional
properties in the future will depend on our ability to conduct operations, to
evaluate and select suitable properties and to consummate transactions in this
highly competitive environment. In addition, most of our competitors have
operated for a much longer time than we have and have demonstrated the ability
to operate through industry cycles.

Hedging transactions may limit our potential gains.

   In order to manage our exposure to price risks in the marketing of our oil
and natural gas production, we have in the past and may in the future enter
into oil and natural gas price hedging arrangements with respect to a portion
of our expected production. Our hedging arrangements may include futures
contracts on the New York Mercantile Exchange. While intended to reduce the
effects of volatile oil and natural gas prices, such transactions may limit our
potential gains if oil and natural gas prices were to rise substantially over
the price established by the hedge. In addition, such transactions may expose
us to the risk of loss in certain circumstances, including instances in which:

  . our production is less than expected;

  . there is a widening of price differentials between delivery points for
    our production and the delivery point assumed in the hedge arrangement;

  . the counterparties to our future contracts fail to perform the contracts;
    or

  . a sudden, unexpected event materially impacts oil or natural gas prices.

   We have recently entered into fixed price swap agreements covering 2,000
barrels per day of our oil production for the period March through October 2000
at an average price of $25.96 per barrel. These agreements cover approximately
66% of our current daily oil production. The price used to determine the
settlement amount is the average of the near month contract on the NYMEX.
Settlement is on the 23rd of each month for the preceding month. The hedging
agreements are with financial institutions that participate in our credit
facility.

   We have also recently entered into a forward sale agreement for 3,750 Mcf of
natural gas per day for the period May through August 2000 at an average price
of $3.05 per Mcf. This agreement covers approximately 9% of our current daily
natural gas production.

The loss of key personnel could adversely affect our ability to operate.

   Our management changed significantly with W/E LLC's investment. We have
three new directors, a new chief executive officer and a number of other new
management and professional personnel. Our operations will be dependent upon
retaining this group of key management and technical personnel. Recognizing
their importance, we have entered into employment agreements with Floyd C.
Wilson, R. A. Walker and Stephen W. Herod. We cannot assure you that such
individuals will remain with us for the immediate or foreseeable future. If we
cannot retain our current personnel or attract additional experienced
personnel, our ability to compete could be adversely affected.

We are subject to complex laws and regulations, including environmental
regulations, that can adversely affect the cost, manner or feasibility of doing
business.

   Our operations are subject to numerous laws and regulations governing the
operation and maintenance of our facilities and the discharge of materials into
the environment or otherwise relating to environmental protection. These laws
and regulations may:

  . require that we acquire permits before commencing drilling;

  . restrict the substances that can be released into the environment in
    connection with drilling and production activities;

  . limit or prohibit drilling activities on protected areas such as wetlands
    or wilderness areas; or

  . require remedial measures to mitigate pollution from former operations,
    such as plugging abandoned wells.

                                       16
<PAGE>

   Under these laws and regulations, we could be liable for personal injury and
clean-up costs and other environmental and property damages, as well as
administrative, civil and criminal penalties. We maintain limited insurance
coverage for some but not all of the environmental damages for which we could
be liable. Moreover, we do not believe that insurance coverage for the full
potential liability that could be caused by sudden and accidental environmental
damages is available at a reasonable cost. Accordingly, we may be subject to
liability or we may be required to cease production from properties in the
event of environmental damages.

   These laws and regulations have been changed frequently in the past. In
general, these changes have imposed more stringent requirements that increase
operating costs or require capital expenditures in order to remain in
compliance. It is also possible that unanticipated developments could cause us
to make environmental expenditures that are significantly different from those
we currently expect. Existing laws and regulations could be changed, and any
changes could have an adverse effect on our business.

Shares eligible for future sale by our current stockholders could adversely
affect the market price of our common stock.

   Sales of a substantial number of shares of our common stock in the market
may have an adverse affect on the price of our stock. After giving effect to
the 6,250,000 shares to be issued in this offering approximately 12,672,181
shares of common stock will be outstanding, assuming the underwriters' over-
allotment option is not exercised. In addition, options and other warrants to
purchase 2,149,636 shares are outstanding, of which 1,559,084 are currently
exercisable. These options and warrants are exercisable at prices ranging from
$9.00 to $30.00 per share. We also have preferred stock outstanding which is
currently convertible into 1,430,840 additional shares of common stock.
Approximately 6.8 million shares of our common stock, assuming that the over-
allotment option is not exercised by the underwriters, will be freely tradable
without substantial restrictions or the requirement of future registration
under the Securities Act of 1933, as amended. In addition, upon demand, and
assuming exercise of the options, warrants and convertible securities, we are
obligated under certain registration rights agreements to file registration
statements to register for resale up to an aggregate of 6,011,452 shares of
common stock. Our officers and directors who are stockholders and a number of
other stockholders, including W/E LLC, Kaiser-Francis Oil Company and certain
other significant stockholders have entered into lock-up agreements under which
they have agreed not to offer or sell any shares of common stock or similar
securities for a period of up to 180 days from the date of this prospectus
without the prior written consent of Bear, Stearns & Co. Inc. ("Bear Stearns")
on behalf of the underwriters; however, Bear Stearns may at any time waive the
terms of these lock-up agreements as specified in the underwriting agreement.
Sales of substantial amounts of common stock, or a perception that such sales
could occur, and the existence of options or warrants to purchase shares of
common stock at prices that may be below the then current market price of the
common stock could adversely affect the market price of our common stock and
could impair our ability to raise capital through the sale of our equity
securities.

                           FORWARD-LOOKING STATEMENTS

   This prospectus and the information incorporated by reference contain
statements that constitute "forward-looking statements" within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. These statements appear in a
number of places and include statements regarding our plans, beliefs,
intentions or current expectations, including those plans, beliefs, intentions
and expectations of our officers and directors with respect to, among other
things:

  . budgeted capital expenditures;

  . increases in oil and natural gas production;

  . the assessment of our Year 2000 compliance;

  . our outlook on oil and natural gas prices;

  . estimates of our oil and natural gas reserves;

  . our future financial condition or results of operations;

  . our pending acquisition of the CWR Properties; and

  . our business strategy and other plans and objectives for future
    operations.

   More specifically, some of the statements contained in this prospectus under
"Prospectus Summary," "Risk Factors," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business and Properties"
that relate to our business and the industry in which we operate are forward-
looking. Statements or assumptions related to or underlying these forward-
looking statements include, without limitation, statements regarding:

  . the quality or value of our properties with regard to, among other
    things, the existence of reserves in economic quantities;

  . our ability to increase our reserves through exploration and development
    activities;

  . the number of locations to be drilled and the time frame within which
    they will be drilled;

  . future prices of oil and natural gas;

  . anticipated domestic demand for oil and natural gas; and

  . the adequacy of our capital resources and liquidity.

   Actual results may differ materially from those suggested by the forward-
looking statements for various reasons, including those discussed under "Risk
Factors."

                                USE OF PROCEEDS

   We estimate that the net proceeds to us from the sale of the 6,250,000
shares of common stock in this offering will be approximately $46.0 million
(approximately $53.5 million if the underwriters' over-allotment option is
exercised in full), after deducting underwriting discounts and commissions and
estimated offering expenses of $4.0 million.

   Pending application of the net proceeds to fund further acquisition,
development, and exploration activities, we intend to use all of the net
proceeds from this offering to repay a portion of our outstanding debt under
our credit facility.

   At March 31, 2000, we had $83.5 million outstanding under our credit
facility bearing interest at an average rate of 7.8%. We expect the amount
outstanding under our credit facility to increase by $52.0 million as a result
of additional borrowings to fund the acquisition of the CWR Properties. The
credit facility matures on November 30, 2002. We have used borrowings under the
credit facility to fund a portion of our acquisitions and for other corporate
purposes.

   On April 28, 2000, the last reported sale price of our common stock on the
Nasdaq SmallCap Market was $8.00 per share.

   On April 28, 2000, there were 952 holders of record of our common stock.

   We have never declared or paid any cash dividends on our common stock. We
currently intend to retain future earnings, if any, for the operation and
development of our business and do not anticipate paying any cash dividends on
our common stock in the foreseeable future. In addition, our credit facility
prohibits us from paying cash dividends on our common stock. Any future
dividends are also restricted by the terms of our outstanding preferred stock
and may be restricted by any loan agreements which we may enter into from time
to time.

   We are obligated to pay net cash dividends in the amounts of approximately
$570,000 per year on our Series C Preferred Stock and dividends of $740,000 per
year on our Series D Preferred Stock, which may be paid, at our option, in cash
or in additional shares of Series D Preferred Stock during the three years
ending February 2, 2003. Our credit facility permits the payment of cash
dividends on our Series C Preferred Stock and the payment of dividends on the
Series D Preferred Stock in additional shares of Series D Preferred Stock.

   The following table presents our capitalization as of December 31, 1999, on
the following bases:

  . on an historical basis;

  . on a pro forma basis giving effect to the acquisition of Magellan and the
    pending acquisition of the CWR Properties; and

  . on a pro forma basis as adjusted to reflect our anticipated use of the
    estimated net proceeds of this offering, assuming that the underwriters'
    over-allotment option is not exercised.

historical consolidated financial statements of 3TEC and the historical
statements of revenues and direct operating expenses of the Floyd Oil

   The pro forma financial data are based upon assumptions and include
adjustments as explained in the notes to the unaudited pro forma condensed
consolidated financial statements, and the actual recording of the transactions
could differ. The unaudited pro forma financial data are not necessarily

Unaudited Pro Forma Supplemental Oil and Natural Gas Disclosure

   The following tables set forth certain unaudited pro forma information
concerning 3TEC's proved oil and natural gas reserves at December 31, 1999,
giving effect to the acquisition of the CWR Properties as if they had occurred
on January 1, 1999. There are numerous uncertainties inherent in estimating the
quantities of proved reserves and projecting future rates of production and
timing of development expenditures. The following reserve data represent
estimates only and should not be construed as being exact. The proved oil and
natural gas reserve information is as of December 31, 1999 and reflects prices
and costs in effect as of such date.

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

   You should read the following discussion and analysis in conjunction with
our audited consolidated financial statements and our unaudited consolidated
financial statements included in this prospectus. The following information
contains forward-looking statements. See "Forward-Looking Statements."

Overview

   We are engaged in the acquisition, development, production and exploration
of oil and natural gas reserves. Our properties are concentrated in East Texas
and the Gulf Coast region, both onshore and in the shallow waters of the Gulf
of Mexico. We also own significant properties in the Permian and San Juan
basins and in the Mid-Continent region. Our management and technical staff have
substantial experience in each of these areas. As of December 31, 1999, not
including Magellan or the CWR Properties, we had estimated total net proved
reserves of 218.7 Bcfe, of which approximately 73% were natural gas and
approximately 82% were proved developed, with an estimated PV-10 value of
$198.6 million. As of March 31, 2000, our net daily production was
approximately 42 Mmcf of natural gas and 3.3 MBbls of oil or 62 Mmcfe.

   We have increased our reserves and production principally through
acquisitions. We focus on properties that have a substantial proved reserve
component and which management believes to have additional exploitation
opportunities. In early 2000, through the acquisition of Magellan, we acquired
a number of drilling prospects covered by an extensive 3-D seismic database
that we believe have exploration potential. We have assembled an experienced
management team and technical staff with expertise in property acquisitions and
development, reservoir engineering, exploration and financial management.

   We underwent a change of control in August 1999, in a transaction in which
W/E Energy Company, LLC (formerly 3TEC Energy Company, LLC) invested $21.4
million in cash and oil and natural gas properties for common stock, warrants
and subordinated notes representing at that time approximately 36% of our then
outstanding common stock.

   Since our formation in 1992, we have grown principally through several
acquisitions of proved properties in the Gulf Coast and Mid-Continent regions.
Acquisitions made in 1997 and 1998 significantly increased our reserves and
production but were primarily nonoperated properties with high per Mcfe lease
operating costs. Following the change in control discussed above, during the
second half of 1999 and the first quarter of 2000, we closed several
transactions that changed our senior management team, capital structure and our
property base. In addition, we added several experienced professionals to our
technical staff. Because of these recent transactions, the historical results
of operations and cash flows will differ materially from, and will not be
representative of, our future results.

   We increased our asset base substantially and decreased our operating cost
per Mcfe on a pro forma basis with the acquisition of the Floyd Oil Properties
in November 1999. The Floyd Oil Properties had estimated net proved reserves at
December 31, 1999, of 165.5 Bcfe with a PV-10 value of $146.1 million. On a pro
forma basis, the Floyd Oil Properties resulted in additional EBITDAX of $17.9
million and $20.6 million and additional pro forma revenues of $34.1 million
and $33.8 million for the years ended 1998 and 1999, respectively. Also on a
pro forma basis, after giving effect to the acquisition of the Floyd Oil
Properties, our total operating cost per Mcfe for the years ended 1998 and 1999
declined 10% and 1% to $0.95 and $0.84, respectively. Pro forma general and
administrative cost per Mcfe for the same periods declined 45% and 50% to $0.32
and $0.30, respectively. Revenues and expenses from the Floyd Oil Properties
are included in our historical operating results only for the period from
November 23, 1999, the date of acquisition, through December 31, 1999.

   Additionally, in February 2000 we closed the acquisition of Magellan, which
owns primarily proved undeveloped reserves, with significant 3-D seismic data.
We plan to fund a development program of Magellan's

                                       28
<PAGE>

undeveloped properties, which we believe could increase future reserves and
production. In addition, we are continually seeking and reviewing acquisitions
of properties and companies which we believe will be complementary to our
reserves and production. We expect our acquisition program to continue to be a
significant source of growth for us, depending on the market for oil and
natural gas properties, and industry conditions generally.

   On April 14, 2000, we entered into a definitive agreement to acquire the CWR
Properties for cash consideration consisting of approximately $52 million. The
acquisition is subject to satisfaction of customary closing conditions, and is
expected to close on or before May 31, 2000. This offering is contingent on the
closing of the purchase of the CWR Properties. The CWR Properties are located
in Upshur and Gregg Counties in East Texas and consist of 178 gross wells (46
net wells) and cover 35,706 gross acres (8,926 net acres). According to Ryder
Scott, at December 31, 1999, the CWR Properties had net proved reserves of 63.9
Bcfe with an associated PV-10 value of $54.9 million. These proved reserves are
approximately 92% natural gas and 50% of the volumes are classified as proved
developed. On a pro forma basis, the CWR Properties contributed an additional
EBITDAX of $7.5 million and $           million, and additional revenues of $11
million and $       million for the year ended December 31, 1999, and the three
months ended March 31, 2000, respectively. Also on a pro forma basis, after
giving effect to the acquisition of the Floyd Oil Properties and the CWR
Properties, our depreciation, depletion and amortization per Mcfe for the year
ended December 31, 1999, and the three months ended March 31, 2000, declined
from 1999 historical amounts 27% and    % to $0.61 and $      , respectively.
Pro forma general and administrative costs per Mcfe for the same periods
declined from 1999 historical amounts 55% and    % to $.27 and $      ,
respectively. See "Description of the CWR Properties."

Certain Accounting Practices

   We use the successful efforts method of accounting for our investments in
oil and natural gas properties. Under this method, we capitalize all direct
costs incurred in connection with the acquisition, drilling and development of
productive oil and natural gas properties. Costs associated with unsuccessful
exploration are expensed as incurred. Geological and geophysical costs and
costs of carrying and retaining unevaluated properties are expensed as
incurred. Depreciation, depletion and amortization of capitalized costs are
computed separately for each field based on the unit of production method using
only proved oil and natural gas reserves.

   We review our oil and natural gas properties on a field level for impairment
when circumstances indicate that the capitalized costs less accumulated
depreciation, depletion and amortization (the "Carrying Value") of the property
may not be recoverable. If the Carrying Value of the property exceeds the
expected future undiscounted cash flows, an amount equal to the excess of the
Carrying Value over the fair value of the property is charged to operations. An
impairment results in a non-cash charge to earnings but does not affect cash
flows unless our borrowing base was significantly reduced as a result of the
impairment.

Liquidity and Capital Resources

   We believe that our cash flows from operations are adequate to meet the
requirements of operating our business. However, future cash flows are subject
to a number of variables, including our level of production and prices, and we
cannot assure you that operations and other capital resources will provide cash
in sufficient amounts to maintain planned levels of capital expenditures. Our
principal operating sources of cash include sales of oil and natural gas
production.

   Our pro forma EBITDAX, including the Floyd Oil Properties and the CWR
Properties, for the year ended December 31, 1999, and the three months ended
March 31, 2000, was $36.4 million and $      million, respectively. For the
year 2000, we have budgeted approximately $20 million for development and
exploration capital expenditures, including an estimated $3.4 million with
respect to the CWR Properties. We are obligated to pay dividends of
approximately $570,000 per year on the Series C Preferred Stock in cash and
dividends of $740,000 per year on the Series D Preferred Stock which we may pay
in either cash or in additional shares of Series D Preferred Stock during the
three years ending February 2, 2003. We are obligated to pay interest on the
convertible subordinated notes of approximately $1.2 million per year.

   Our primary source of financing for acquisitions has been borrowing under
our credit facility, discussed below. We have also recently utilized private
equity financing to supplement our capital requirements. We believe we will
have sufficient cash flow from operations and borrowings under our credit
facility to meet our obligations and operating needs for the coming year. We
also believe that we have the ability to raise additional private equity or
debt financing and otherwise access the capital markets should such sources of
capital prove insufficient to execute our strategic objectives. However, future
cash flows are subject to a number of variables, including our level of
production and prices, and we cannot assure you that operations and other
capital resources will provide cash in sufficient amounts to maintain planned
levels of capital expenditures.

   In connection with our acquisition of the Floyd Oil Properties on November
23, 1999, we entered into a $250 million credit facility with Bank One, Texas,
N.A. and certain other financial institutions. Our then existing bank debt of
$26.6 million was paid in full with proceeds from the new facility. The credit
facility provides for a borrowing base which is adjusted periodically on the
basis of the discounted present value attributable to our proved producing oil
and natural gas reserves, as determined by our lenders. The credit facility
currently provides for a $95 million borrowing base. The borrowing base will be
redetermined semi-annually on May 1 and November 1 of each year. Interest under
the facility accrues at our option at a rate calculated as either the bank's
prime rate plus 25 basis points or LIBOR plus basis points increasing from a
low of 125 to a high of 187.5 as loans outstanding increase as a percentage of
the borrowing base. At March 31, 2000 we were paying 7.8% per annum interest on
the entire principal balance of the facility of $83.5 million. The loan matures
on November 30, 2002. Prior to maturity, no payments of principal are required
so long as the borrowing base exceeds the loan balance. The borrowings under
the facility are secured by substantially all of our properties. At March 31,
2000, the amount available to be borrowed under the credit facility was
approximately $11.5 million.

   In connection with this credit facility, we are required to adhere to
certain affirmative and negative covenants. The loan agreement contains a
number of dividend restrictions and restrictive covenants which, among other
things, require the maintenance of a minimum current ratio interest coverage
ratio.

   In connection with our pending acquisition of the CWR Properties we have
begun negotiations with the lenders participating in our credit facility to
increase the amount of availability under the borrowing base by an amount which
would enable us to borrow substantially all of the purchase price of the CWR
Properties. These negotiations are ongoing and the lenders have indicated a
preliminary willingness to increase our available borrowing capacity by an
amount which would enable us to borrow substantially all of the purchase price
of the CWR Properties. As indicated elsewhere in this prospectus, the net
proceeds of this offering will be used principally to repay indebtedness
outstanding under this credit facility.

   We generally sell our oil at local field prices paid by the principal
purchasers of oil. The majority of our natural gas production is sold at spot
prices. Accordingly, we are generally subject to the commodity prices for these
resources as they vary from time to time. Prices since mid-1999 have generally
followed an increasing trend, but the market continues to have considerable
volatility. We have entered into fixed price swap agreements covering 2,000
barrels per day of our oil production for the period March through October 2000
at an average price of $25.96 per barrel. These agreements cover approximately
66% of our current daily oil production. The price used to determine the
settlement amount is the average of the near month contract on the NYMEX.
Settlement is on the 23rd of each month for the preceding month. The hedging
agreements are with financial institutions that participate in our credit
facility.

   We have entered into a forward sale agreement for 3,750 Mcf of natural gas
per day for the period May through August 2000 at an average price of $3.05 per
Mcf. This agreement covers approximately 9% of our current daily natural gas
production.

   Our revenues and the value of our oil and natural gas properties have been
and will be affected by changes in natural gas and crude oil prices. Our
ability to maintain current borrowing capacity and to obtain additional capital
on attractive terms is also substantially dependent on natural gas and crude
oil prices. These prices are subject to significant seasonal and other
fluctuations that are beyond our ability to control or predict. During

                                       30
<PAGE>

1999, we received an average of $16.88 per barrel of crude oil and $2.18 per
Mcf of natural gas. Although some costs and expenses are affected by the level
of inflation, inflation has not had a significant effect in recent years.
Should conditions in the industry continue to improve, causing an increase in
competition resulting in a relative shortage of oilfield supplies and/or
services, inflationary cost pressures may resume.

Results of Operations

   Our revenue, profitability, and future rate of growth are dependent upon
prevailing prices for oil and natural gas, which, in turn, depend upon numerous
factors such as economic, political, and regulatory developments as well as
competition from other sources of energy. The energy markets historically have
been highly volatile, and future decreases in prices could have an adverse
effect on our financial position, results of operations, quantities of reserves
that may be economically produced, and access to capital.

   Due to our significant property and corporate acquisitions in 1999, our 1999
change of control and our current capitalization structure, comparisons of our
results of operations from year to year may not be meaningful. You should read
the following discussion and analysis together with our audited consolidated
financial statements and the related notes for the fiscal years ended December
31, 1999 and 1998.

Three Months Ended March 31, 2000, compared with Three Months Ended March 31,
1999.

   [Text to be provided by amendment.]

Year Ended December 31, 1999, Compared With Year Ended December 31, 1998

   Revenue. Total revenue for the year ended December 31, 1999, was $22.0
million, an increase of $4.3 million (24%) over total revenue for 1998. Natural
gas revenues for the 1999 period were $10.3 million, approximately 34% higher
than 1998 natural gas revenues of $7.7 million. Natural gas production volumes
increased 23% in 1999; oil production volumes decreased by approximately 9%,
principally as a result of property sales during the period. Oil revenues for
the 1999 period were $8.9 million, approximately 33% higher than 1998 oil
revenues of $6.7 million. Natural gas plant and other product sales revenue of
$648,000 increased 2% from $632,000 in 1998. Average natural gas sale prices
increased 9% from the 1998 to the 1999 period, while oil prices increased 46%
during the same period. For 1999, approximately 52% of the dollar amount of our
product sales were natural gas. In addition, production from the Floyd Oil
Properties from the date of acquisition (November 23, 1999) to year-end
contributed approximately $4.5 million (approximately 20%) to our total
revenues in the 1999 period.

   Gain On Property Sales, Interest and Other Income. In 1999 and 1998, our
property divestments resulted in gains of $1.0 million and $1.9 million,
respectively. Other income for 1999 of $1.0 million, consisted principally of
interest income and a lawsuit settlement.

   Expenses. Total expenses for the year ended December 31, 1999 were $26.9
million, a slight decrease over the $27.1 million in 1998. Comparability of
total expenses was affected by certain non-recurring expenses in 1999 of $1.7
million and additional expenses of $2.3 million attributable to the properties
acquired in the Floyd Oil Acquisition. Lease operating expense of $6.7 million
or approximately $0.85 per Mcfe, decreased by approximately $1.1 million from
the 1998 period, when it was approximately $1.06 Mcfe, reflecting the effect of
property sales. Depreciation and depletion expense was $6.7 million, or
approximately $0.84 per Mcfe, compared to $7.1 million or approximately $0.97
per Mcfe for 1998. An increase in depletion due to the properties acquired in
the Floyd Oil Company Acquisition was offset by lower depletion due to
impairments, property sales and lower production on properties owned the entire
period of 1999. Impairment expense for 1999 was approximately $2.5 million,
relating to impairments on fee mineral acreage, non-producing leasehold and
proved oil and natural gas properties. More specifically, 1999 impairments were
related to certain fee mineral acreage that reverted to the landowners,
management's decision not to participate in additional exploration on certain
prospects and new reserve engineers employed by us resulted in valuation
changes on

                                       31
<PAGE>

certain proved properties. The impairment expense in 1998 was principally
attributable to decreasing oil prices. General and administrative expense was
$4.7 million, or approximately $0.60 per Mcfe, compared to $4.3 million or
approximately $0.58 per Mcfe for 1998. The general and administrative expense
increase was primarily the result of increases in salary, legal and consulting
expenses in 1999 offset partially by declines in certain expenses due to the
closing of subsidiary offices in Kingwood, Texas. Interest expense of $3.2
million, increased $1.23 million (62%) in the 1999 period, the increase
reflecting increased borrowings under our credit facility for acquisitions.

   The non-recurring expense of $1.7 million was triggered by the change of
control resulting from the sale of securities to W/E LLC and consists of stock
compensation expense of $730,000, severance payment of $624,000, compensation
plan payment of $292,000 and other expenses of $60,000.

   Net Loss. The net loss for 1999 was approximately $3.4 million compared to a
loss of approximately $6.6 million in 1998. The current period net loss
decreased primarily as a result of the increased income from oil and natural
gas and the lower depletion and impairment expenses.

   Dividends to Preferred Stockholders. Dividends to preferred stockholders of
approximately $574,000 in 1999 increased 745% over 1998. The increase was due
to the dividends on the Series C Preferred Stock that began to accrue dividends
on December 31, 1998 and the conversion of the Series A Preferred Stock to
common stock on January 31, 1998.

Year 2000 Compliance

   We had undertaken various initiatives to ensure that our hardware, software
and equipment functioned properly with the rollover of the date to January 1,
2000. We experienced no problems as a result of the rollover of the dates to
January 1, 2000, and the costs incurred for Year 2000 compliance were
immaterial to our financial position and results of operations. Although we can
provide no assurance, we anticipate any future costs associated with Year 2000
compliance to be immaterial to our financial position and results of
operations.

Accounting Pronouncements

   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 standardizes the accounting
for and disclosures of derivative instruments, including certain derivative
instruments embedded in other contracts. The statement is effective for
financial statements for fiscal years beginning after June 15, 2000. We have
not yet determined the impact of the Statement on our financial condition or
results of operations.

                            BUSINESS AND PROPERTIES

About 3TEC

   We are engaged in the acquisition, development, production and exploration
of oil and natural gas reserves. Our properties are concentrated in East Texas
and the Gulf Coast region, both onshore and in the shallow waters of the Gulf
of Mexico. We also own significant properties in the Permian and San Juan
basins and in the Mid-Continent region. Our management and technical staff have
substantial experience in each of these areas. As of December 31, 1999,
including the recent acquisition of Magellan and the pending acquisition of the
CWR Properties, discussed below, on a pro forma basis we had estimated total
net proved reserves of 309 Bcfe, of which approximately 76% were natural gas,
and approximately 70% were proved developed with an estimated PV-10 value of
$293.6 million. As of March 31, 2000, on a pro forma basis including the CWR
Properties, our actual net daily production was approximately 51.6 Mmcf of
natural gas and 3.4 MBbls of oil or 72.0 Mmcfe.

   We have increased our reserves and production principally through
acquisitions. We focus on properties that have a substantial proved reserve
component and which management believes to have additional exploitation
opportunities. Through the recently completed acquisition of Magellan, we have
also acquired a number of drilling prospects covered by an extensive 3-D
seismic database that we believe have exploration potential. We have assembled
an experienced management team and technical staff with expertise in property
acquisitions and development, reservoir engineering, exploration and financial
management. After this offering, we believe that our cash flow from operations
and our financial resources will provide us with the ability to fully develop
our current properties, to finance our current exploration projects and to
pursue new acquisition opportunities.

   As further discussed below, in August 1999, W/E LLC purchased a controlling
interest in us, and Floyd C. Wilson was named our Chairman and Chief Executive
Officer. Since that time, we have acquired net proved reserves of 192.1 Bcfe
with an associated PV-10 value of $186.2 million at December 31, 1999, and have
entered into an agreement to purchase the CWR Properties with net proved
reserves of 63.9 Bcfe and an estimated PV-10 value of $54.9 million at December
31, 1999, have raised or issued $23.0 million of private equity and equity
linked financing and have entered into a new $250 million credit facility.

Our Strategy

   Our business strategy is focused on the following:

  . Pursuit of Strategic Acquisitions. We continually review opportunities to
    acquire producing properties, leasehold acreage and drilling prospects.
    We seek to acquire operational control of properties that we believe have
    significant exploitation and exploration potential. We are especially
    focused on increasing our holdings in fields and basins in which we
    already own an interest.

  . Further Development of Existing Properties. We intend to further develop
    our properties that have proved reserves. We seek to add proved reserves
    and increase production through the use of advanced technologies,
    including detailed technical analysis of our properties, and by drilling
    in-fill locations and selectively recompleting existing wells. We also
    plan to drill step-out wells to expand known field limits. We intend to
    enhance the efficiency and quality control of these activities by
    operating the majority of our properties.

  . Growth Through Exploration. We conduct an active technology-driven
    exploration program that is designed to complement our property
    acquisition and development drilling efforts with moderate to high risk
    exploration projects that have greater reserve potential. We generate
    exploration prospects through the analysis of geological and geophysical
    data and the interpretation of 3-D seismic data. We intend to manage our
    exploration expenditures through the optimal scheduling of our drilling
    program and by selectively reducing our participation in certain
    exploratory prospects through sales of interests to industry partners.

                                       33
<PAGE>

  . Rationalization of Property Portfolio. We intend to actively pursue
    opportunities to reduce and control operating costs of our existing
    properties and properties we may acquire in the future through the
    consolidation of overlapping operations, the sale of marginal properties
    and by increasing the number of fields we operate as a percentage of our
    total properties.

  . Maintenance of Financial Flexibility. We intend to maintain a substantial
    unused borrowing capacity under our bank credit facility by periodically
    refinancing our bank debt in the capital markets when conditions are
    favorable. We believe our expanded base of internally generated cash flow
    and other financial resources, including our existing financial partners,
    provide us with the financial flexibility to pursue additional
    acquisitions of producing properties and leasehold acreage and to develop
    our project inventory in an optimal fashion.

Our Strengths

   We believe our historical success and future performance are, and will be,
directly related to the following combination of strengths:

  . Proven Acquisition Experience. Since the investment by W/E LLC in August
    1999, through the acquisition of the Floyd Oil Properties, Magellan and
    the pending acquisition of the CWR Properties, we have added
    approximately 256 Bcfe of proved reserves with a PV-10 value of $281
    million as of December 31, 1999. Our acquisition efforts are managed by
    an experienced team of property aggregators with extensive engineering,
    operating and financial skills.

  . Experienced Technical Team. Our technical team is comprised of respected
    energy industry professionals with an average of over 20 years of
    industry experience.

  . Substantial Inventory of Development and Exploration Prospects. Including
    the CWR Properties, we have assembled an inventory of over 200 drilling
    locations balanced between what we believe to be low to moderate risk
    development locations and higher risk, higher potential exploratory
    locations defined by, and supported with, 3-D seismic data. Our inventory
    of drilling locations and degree of operating control provide us
    flexibility in project selection and the timing of drilling projects.

  . Financial Flexibility. We have access to capital and the financial
    flexibility to respond quickly to opportunities for growth and changing
    business conditions.

Recent Acquisition of Magellan

   On February 3, 2000, we completed the acquisition of Magellan from certain
affiliates of EnCap and other third parties for consideration of approximately
$18.6 million, consisting of: (a) 1,085,934 shares of common stock, (b) four
year warrants to purchase up to 333,333 shares of common stock at $30.00 per
share, (c) 617,008 shares of 5% Series D Preferred Stock and (d) the assignment
of a performance based "back-in" working interest of 5% of Magellan's interest
in 12 exploration prospects. For a more detailed description of the Series D
Preferred Stock, see "Description of Capital Stock." Magellan's properties are
located both onshore and in the shallow waters of south Louisiana and consist
of 20,243 gross (10,748 net) acres in three prospective areas. As of December
31, 1999, Magellan's independent reserve engineers, Ryder Scott, estimated that
Magellan's net proved reserves were 26.6 Bcfe with an associated PV-10 value of
$40.1 million. These proved reserves are approximately 66% natural gas and 81%
of the volumes are classified as proved undeveloped. Magellan operates
approximately 80% of its properties on a PV-10 value basis. In addition to the
proved reserves, we believe the Magellan properties contain several 3-D seismic
defined exploratory drilling locations. See "Description of Magellan
Properties."

   If requested by the holders of the securities we issued in the Magellan
transaction, we will be obligated to file no more than two registration
statements to register their common stock received in the transaction or in
conversion of the Series D Preferred Stock or exercise of the related warrants
and, if necessary, to keep the registration statements effective for up to two
years. We have also agreed to give notice to recipients of the

                                       34
<PAGE>

securities if we propose to file a registration statement. These persons or
entities have the right to include their common stock in any resulting
registration statement.

Pending Acquisition of CWR Properties

   On April 14, 2000, we entered into a definitive agreement to acquire the CWR
Properties for cash consideration consisting of approximately $52 million. The
acquisition is subject to satisfaction of customary closing conditions, and is
expected to close on or before May 31, 2000. This offering is contingent upon
the closing of the purchase of the CWR Properties. The CWR Properties are
located in Upshur and Gregg Counties in East Texas and consist of 178 gross
wells (46 net wells) and cover 35,706 gross acres (8,926 net acres). As of
December 31, 1999, Ryder Scott estimated that the net proved reserves of the
CWR Properties were 63.9 Bcfe with an associated PV-10 value of $54.9 million.
These proved reserves are approximately 92% natural gas and 50% are classified
as proved producing. See "Description of CWR Properties."

   The definitive agreement provides that if we acquire the right to operate
the CWR Properties, which are currently operated by unrelated third parties,
the purchase price would increase by approximately $3.0 million. We will
endeavor to acquire these operating rights but are not assured of success. In
the event we do acquire the operating rights, the PV-10 value of our interest
in the reserves underlying the CWR Properties would increase because the
effective costs to us of operating the properties would be reduced.

Our Formation

   3TEC is the successor to Middle Bay Oil Company, Inc. ("Middle Bay"), an
Alabama corporation formed on November 30, 1992. 3TEC was incorporated in
Delaware on November 24, 1999, as a wholly owned subsidiary of Middle Bay for
the sole purpose of merging with Middle Bay to effect a change in domicile to
Delaware and to change our name to 3TEC Energy Corporation. Effective December
7, 1999, Middle Bay was merged into us and each share of common stock of Middle
Bay was converted into one share of our common stock.

Description of Our Properties

   We present information regarding our oil and natural gas reserves,
properties, and operating results below. The information below relating to oil
and natural gas reserves, volumes, prices, operating expenses, productive
wells, and acreage data, includes the recently acquired Floyd Oil Properties
and Magellan, as well as information relating to the pending acquisition of the
CWR Properties. Information relating to volumes, prices, and operating
expenses, set forth below are presented on a pro forma basis as if we acquired
the Floyd Oil Properties, the CWR Properties and Magellan on December 31, 1999.
We acquired the Floyd Oil Properties in November 1999, Magellan in February
2000, and intend to acquire the CWR Properties on or before May 31, 2000.

   We describe our properties by operating area in the paragraphs which follow.

   We separately describe the Magellan and CWR Properties under the captions
"Description of the Magellan Properties" and "Description of the CWR
Properties," below.

   East Texas Area. Our properties in the East Texas region produce primarily
from the Cotton Valley and Travis Peak formations which range in depth from
approximately 7,000 feet to 10,500 feet. As of December 31 1999, our estimated
net daily production from this area was 10.6 Mmcfe per day. The producing
formations of this area tend to contain multiple producing horizons and are
typically low permeability sands that require fracture stimulation to achieve
optimal producing rates. This type of fracture stimulation usually results in
relatively high initial production rates that decline rapidly during the first
year of production and subsequently stabilize at fairly low, more easily
predictable annual decline rates. Much of our production in this area is from
wells that have been producing for several years and are in their latter, more
stable stage of production, resulting in a relatively long reserves to
production ratio. Additionally, reservoirs with multiple producing horizons
typically provide numerous recompletion and workover opportunities to enhance
proved reserves and production. We have identified 53 proved undeveloped
drilling locations in this area. Many of these development drilling locations
are based on a change in regulatory field rules that now permit wells to be
drilled on 80 acre spacing as opposed to 160 acre spacing. This type of infill
drilling is generally effective in low permeability sands, such as the Cotton
Valley, where one wellbore is only capable of draining an area less than the
permitted spacing. Drilling infill wells on 80 acre spacing has been successful
throughout the area in such notable Cotton Valley fields as Carthage, Oak Hill
and Willow Springs. For 2000, we have budgeted approximately $3.7 million for
the drilling of development wells and various exploitation activities.

   Gulf Coast Area. We have established a substantial base of proved reserves
and undeveloped acreage with significant exploration potential along the Gulf
Coast of Texas and Louisiana. As of December 31, 1999, our estimated net daily
production from this area was 17.8 Mmcfe per day. Onshore in southern Louisiana
and southeast Texas our production is mainly from the Hackberry, Miogyp and
Vicksburg formations which range from approximately 13,000 feet to 17,000 feet
in depth. Along the central and southern Texas coast we are active in two main
areas, the Stuart City field in the Edwards Reef trend and the Segundo Olmos
field in Webb County, Texas. The Edwards Reef trend extends from the Mexican
border through the Texas Gulf Coast into southern Louisiana and has been
extensively drilled since the late 1950's. The Edwards Reef trend formation is
a very thick section of low permeability limestone that requires fracture
stimulation to achieve optimal production rates and even then will only drain a
limited area. Our acreage has seven producing wells that were drilled on 320
acre spacing and we have identified seven additional proved undeveloped
locations on this acreage based on drilling infill locations on 120 acre
spacing. Infill drilling has been successful throughout this trend. We are also
evaluating the drilling of new horizontal legs in existing wells and conducting
additional fracture stimulations, both of which have been successful in the
Edwards Reef trend. The Segundo Olmos field produces from the Olmos formation,
a relatively low permeability sandstone, at a depth of approximately 7,000
feet. This field was originally drilled on 160 acre spacing and has been
successfully drilled on 80 acre spacing throughout the trend. We have
identified an additional five proved undeveloped locations in this field. In
2000, we have budgeted approximately $2.9 million for the drilling of
development wells and associated exploitation activity in these areas.

   Permian, San Juan and Mid-Continent Areas. We own interests in numerous
fields in the Anadarko, Arkoma, Permian and San Juan basins in the states of
Kansas, Oklahoma, Texas and New Mexico and our estimated net daily production
as of December 31, 1999, was 28.3 Mmcfe per day. These fields are generally
characterized as mature producing fields that have very stable, low rates of
decline and a relatively small amount of development drilling and exploitation
potential. In 2000, we have budgeted approximately $1.3 million for the
drilling of wells and associated exploitation projects in these areas.

Description of the Magellan Properties

   Through the acquisition of Magellan, we acquired interests in Breton Sound
Block 34 in Louisiana state waters and the Bay De Chene and Garden City fields
in south Louisiana. While there is a relatively small

                                       36
<PAGE>

amount of existing production, all three fields have had 3-D seismic surveys
and in the aggregate have substantial proved undeveloped and proved developed
non-producing reserves. Management believes these properties also have
additional exploration potential. Several experienced engineers and
geoscientists at Magellan, who developed many of the exploration prospects and
have extensive experience in south Louisiana, have joined our technical staff.

   Breton Sound Block 34 is located in 12 feet to 15 feet of water east of the
Main Pass area of the Mississippi River delta. As of December 31, 1999, this
field was producing 0.8 Mmcfe per day net to our interest and has significant
proved developed nonproducing and proved undeveloped reserves in the Krumbar
and Hollywood formations at approximately 15,000 feet to 17,000 feet in depth.
Additionally, we have identified a proved undeveloped location supported by 3-D
seismic data in Breton Sound Block 34 (our "Alpha Prospect") that is
structurally high to an offsetting well drilled by Conoco. In addition to our
Alpha Prospect, we have identified four additional untested fault blocks that
have similar characteristics to our Alpha Prospect based on the interpretation
of the 3-D seismic data. In 2000, we have budgeted approximately $4.5 million
for development drilling and recompletions.

   The Bay De Chene field and the Garden City field are older fields that have
produced substantial amounts of oil and natural gas which we believe to have
further development and exploration potential. The Bay De Chene field is a
highly faulted, geologically complex salt dome based structure that has
produced over 100 MBbls of oil and 230 Bcf of natural gas from over 67
different reservoirs. In 1997, Western Geophysical conducted a 72 square mile
3-D seismic survey resulting in the identification of numerous potential
development drilling locations and exploitation projects and several
exploration drilling prospects. The majority of these opportunities are between
7,000 feet and 10,000 feet in depth and are in reservoirs that have been
productive throughout the field. As of December 31, 1999, this field was
producing 1.0 Mmcfe per day net to our interest. The Garden City field has
produced over 2 Tcfe since its discovery and contains one proved undeveloped
drilling location and several exploration prospects. All of these drilling
opportunities have been evaluated with 3-D seismic and subsurface data. In
2000, we have budgeted approximately $4.1 million for the Bay De Chene and
Garden City fields for development and exploration drilling and recompletions.
We will continue to evaluate our exploration projects in these fields.

Description of the CWR Properties

   The CWR Properties are located in the Glenwood and White Oak fields in Gregg
and Upshur Counties, Texas, and produce from the Cotton Valley formation. As of
December 31, 1999, the properties being acquired had estimated total net proved
reserves of 63.9 Bcfe with a PV-10 value of $54.9 million, using constant
pricing of $2.39 per Mcf for gas and $25.60 per barrel for oil. The estimated
reserves are 92% natural gas on an equivalent basis. Current net daily
production from the properties is approximately 9.6 Mmcf of natural gas and 144
Bbls of oil. Approximately 50% of the reserves are classified as proved
producing. We have identified over 100 proved undeveloped locations and plan an
active drilling program on the properties. The transaction has an effective
date of January 1, 2000 and closing is expected to be on or before May 31,
2000. On a pro-forma basis, this acquisition will increase our total proved
reserves as of December 31, 1999 to 309 Bcfe and increase our net daily
production to approximately 52 Mmcf of gas and 3,400 Bbls of oil. In 2000, we
have budgeted approximately $3.4 million for development drilling on these
properties.

Oil and Natural Gas Reserves

   The following table presents our estimated net proved oil and natural gas
reserves and the PV-10 value of our reserves as of December 31, 1999 and 1998.
The period end prices of oil and natural gas at December 31, 1999 and 1998, in
the PV-10 calculations were $24.02 and $9.50 per barrel of oil and $2.30 and
$2.10 per Mcf of natural gas, respectively. Our estimated net proved oil and
natural gas reserves and the PV-10 value of our reserves as of December 31,
1999 are based on a reserve report prepared by Ryder Scott for our properties.
In 1998 such estimates for our properties were prepared by Lee Keeling and
Associates, Inc. and H.J. Gruy and Associates, Inc. The PV-10 values shown in
the table are not intended to represent the current market value of

                                       37
<PAGE>

the estimated oil and natural gas reserves we own. For further information
concerning the PV-10 values of these proved reserves, please read note 15 of
the notes to our December 31, 1999 consolidated financial statements. The pro
forma reserve information set forth below includes reserve information for
Magellan, which we acquired in February 2000, and for the CWR Properties, which
we intend to acquire on or before May 31, 2000, as though we owned Magellan and
the CWR Properties at December 31, 1999.

   There are numerous uncertainties in estimating quantities of proved reserves
and in projecting future rates of production and the timing of development
expenditures, including many factors beyond our control. The reserve data set
forth in this prospectus are only estimates. Although we believe these
estimates to be reasonable, reserve estimates are imprecise and may be expected
to change as additional information becomes available. Estimates of oil and
natural gas reserves, of necessity, are projections based on engineering data,
and there are uncertainties inherent in the interpretation of this data, as
well as the projection of future rates of production and the timing of
development expenditures. Reservoir engineering is a subjective process of
estimating underground accumulations of oil and natural gas that cannot be
exactly measured. Therefore, estimates of the economically recoverable
quantities of oil and natural gas attributable to any particular group of
properties, classifications of the reserves based on risk of recovery and the
estimates are a function of the quality of available data and of engineering
and geological interpretation and judgment and the future net cash flows
expected therefrom, prepared by different engineers or by the same engineers at
different times may vary substantially. There also can be no assurance that the
reserves set forth herein will ultimately be produced or that the proved
undeveloped reserves will be developed within the periods anticipated. Actual
production, revenues and expenditures with respect to our reserves will likely
vary from estimates, and the variances may be material. In addition, the
estimates of future net revenues from our proved reserves and the present value
thereof are based upon certain assumptions about future production levels,
prices and costs that may not be correct. We emphasize with respect to the
estimates prepared by independent petroleum engineers that PV-10 value should
not be construed as representative of the fair market value of our proved oil
and natural gas properties since discounted future net cash flows are based
upon projected cash flows which do not provide for changes in oil and natural
gas prices or for the escalation of expenses and capital costs. The
meaningfulness of such estimates is highly dependent upon the accuracy of the
assumptions upon which they are based. Actual future prices and costs may
differ materially from those estimated. Prospective purchasers of the common
stock are cautioned not to place undue reliance on the reserve data included in
this prospectus.

Volumes, Prices and Operating Expenses

   The following table presents information regarding the production volumes
of, average sales prices received for, and average production costs associated
with, our sales of oil and natural gas for the periods indicated. The oil and
natural gas production from the Floyd Oil Properties, during the period from
acquisition on November 23, 1999, to December 31, 1999, was 87 MBbls of oil and
1,112 Mmcf of natural gas. Pro forma adjustments give effect to the
acquisitions of the Floyd Oil Properties and the CWR Properties, as if the
acquisitions had occurred at January 1, 1999.

   At December 31, 1999, Magellan owned 17,049 gross developed acres, or 8,842
net developed acres, and 3,193 gross undeveloped acres, or 1,906 net
undeveloped acres. The CWR Properties information included in the table above
consists of 35,706 gross developed acres, or 8,926 net developed acres, and no
gross undeveloped acres or net undeveloped acres. Excluded from the acreage
data are approximately 35,214 net mineral acres owned by us, primarily in
LaFourche, St. Mary and Terrebonne parishes of Louisiana, all of which we
believe have potential for oil and natural gas exploration.

Marketing

   We have marketed the oil and natural gas produced from our properties
through typical channels for these products. We generally sell our oil at local
field prices paid by the principal purchasers of oil. The majority of our
natural gas production is sold at spot prices.

   Both oil and natural gas are purchased by marketing companies, pipelines,
major oil companies, public utilities, industrial customers and other users and
processors of petroleum products. We are not confined to, or dependent upon,
any one purchaser or small group of purchasers. Accordingly, the loss of a
single purchaser, or a few purchasers, would not have a long-term material
effect on our business because there are numerous purchasers in the areas in
which we sell our production.

Competition

   We face competition from other oil and natural gas companies in all aspects
of our business, including acquisition of producing properties and oil and
natural gas leases, marketing of oil and natural gas, and obtaining goods,
services and labor. Many of our competitors have substantially larger financial
and other resources. Factors that affect our ability to acquire producing
properties include available funds, available information about the property
and our standards established for minimum projected return on investment.
Competition is also presented by alternative fuel sources, including heating
oil and other fossil fuels. We believe that we are competing and will compete
effectively as a result of our expertise in the acquisition, exploration, and
development of oil and natural gas reserves and our financial ability to take
advantage of such opportunities.

Regulation

   Federal Regulation of Transportation of Natural Gas. Historically, the
transportation and sale for resale of natural gas in interstate commerce have
been regulated by the Natural Gas Act of 1938, the Natural Gas Policy Act of
1978, and the regulations promulgated by the Federal Energy Regulatory
Commission. In the past, the

                                       41
<PAGE>

federal government has regulated the prices at which natural gas could be sold.
Deregulation of natural gas sales by producers began with the enactment of the
Natural Gas Policy Act. In 1989, Congress enacted the Natural Gas Wellhead
Decontrol Act, which removed all remaining Natural Gas Act and Natural Gas
Policy Act price and non-price controls affecting producer sales of natural gas
effective January 1, 1993. Congress could, however, reenact price controls in
the future.

   Our sales of natural gas are affected by the availability, terms and cost of
pipeline transportation. The price and terms for access to pipeline
transportation remain subject to extensive federal regulation. Beginning in
April 1992, the Federal Energy Regulatory Commission issued Order No. 636 and a
series of related orders, which required interstate pipelines to provide open-
access transportation on a basis that is equal for all natural gas suppliers.
The Federal Energy Regulatory Commission has stated that it intends for Order
No. 636 to foster increased competition within all phases of the natural gas
industry. Although Order No. 636 does not directly regulate our production and
marketing activities, it does affect how buyers and sellers gain access to the
necessary transportation facilities and how we and our competitors sell natural
gas in the marketplace. The courts have largely affirmed the significant
features of Order No. 636 and the numerous related orders, although some
appeals remain pending and the Federal Energy Regulatory Commission continues
to review and modify its regulations regarding the transportation of natural
gas. One broad and significant pending review involves examination of several
questions, including whether the transportation regulations should be changed
to better operate together with changes in state law that are introducing
competition in retail natural gas markets, whether the historical method of
setting transportation rates based on cost should be changed for certain
transportation, whether short term transportation capacity should be allocated
based only on auctions, and whether additional changes need to be made to long
term transportation policies to prevent a market bias in favor of short term
transportation. We cannot predict what action the Federal Energy Regulatory
Commission will take on these matters, nor can we accurately predict whether
the Federal Energy Regulatory Commission's actions will achieve the goal of
increasing competition in markets in which our natural gas is sold. However, we
do not believe that any action taken will affect us in a way that materially
differs from the way it affects other oil and natural gas producers.

   Additional proposals and proceedings that might affect the natural gas
industry are pending before Congress, the Federal Energy Regulatory Commission
and the courts. The natural gas industry historically has been very heavily
regulated; therefore, we cannot assure you that the less stringent regulatory
approach recently pursued by the Federal Energy Regulatory Commission and
Congress will continue.

   Federal Regulation of Transportation of Oil. Oil and sales of oil,
condensate and natural gas liquids by us are not currently regulated and are
made at market prices. Effective as of January 1, 1995, the Federal Energy
Regulatory Commission implemented regulations establishing an indexing system
for transportation rates for interstate common carrier oil pipelines. These
rates are generally indexed to inflation, subject to conditions and
limitations. These regulations may, over time, tend to increase transportation
costs or reduce wellhead prices for oil. However, we do not believe that these
regulations affect us any differently than other oil and natural gas producers,
gatherers and marketers.

   State Regulation. Our oil and natural gas operations are subject to various
types of regulation at the state and local levels. These regulations require
drilling permits, regulate the methods for developing new fields and the
spacing and operating of wells and waste prevention, and sometimes impose
production limitations. These regulations may limit our production from wells
and the number of wells or locations we can drill.

   Some states have adopted regulations with respect to gathering systems.
These regulations have not had a material effect on the operation of our
gathering systems, but we cannot predict whether any future regulations in this
area may have a material impact on our gathering systems.

   Federal, State and Indian Leases. Our operations on federal, state or Indian
oil and natural gas leases are subject to numerous restrictions, including
nondiscrimination statutes. We must conduct our operations on these leases
pursuant to permits and authorization and other regulations issued by the
Bureau of Land Management,

                                       42
<PAGE>

Minerals Management Service and other agencies. The Minerals Management Service
currently has under consideration a proposal to change the manner in which
crude oil is valued for purposes of calculating royalty due the government. If
adopted, these changes would decrease reliance on historical valuation methods
and instead adopt an indexing method intended to better reflect market value,
but which may not reflect the proceeds actually received in the sale of the
oil. We cannot predict what action the Minerals Management Service may
ultimately take or how it will affect royalty payable on our production from
federal leases, however, if adopted the changes may tend to increase costs of
royalty payments.

   Environmental Regulations. Our operations are subject to numerous laws and
regulations governing the discharge of materials into the environment or
otherwise relating to environmental protection. Our exploration and production
operations and facilities for gathering, treating, processing and handling
hydrocarbons and related exploration and production wastes are subject to
stringent environmental regulation. These laws and regulations sometimes
require government approvals before activities occur, limit or prohibit
activities because of protected areas or species, impose substantial
liabilities for pollution and provide penalties for noncompliance. As with the
industry generally, compliance with existing and anticipated regulations
increases our overall cost of business. These regulations, however, generally
affect us and our competitors similarly. Environmental laws and regulations are
subject to frequent change, and we are not able to predict the costs or other
impacts of environmental regulation on our future operations.

   The Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without
regard to fault or the legality of the original conduct, on some classes of
persons that are considered to have contributed to the release or threat of
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 and for damages to natural resources, 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.

   Our operations are also subject to regulation of air emissions under the
Clean Air Act and comparable state and local requirements. Implementation of
these laws could lead to the gradual imposition of new air pollution control
requirements on our operations. As a result, we may incur capital expenditures
over the next several years to upgrade our air pollution control equipment. We
do not believe that our operations would be materially affected by any such
requirements, nor do we expect such requirements to be any more burdensome to
us than to other companies our size involved in oil and natural gas exploration
and production activities.

   In addition, legislation has been proposed in Congress from time to time
that would reclassify some oil and natural gas exploration and production
wastes as "hazardous wastes," which would make the reclassified wastes subject
to much more stringent handling, disposal and clean-up requirements. If
Congress were to enact this legislation, it could increase our operating costs,
as well as those of the oil and natural gas industry in general. Initiatives to
further regulate the disposal of oil and natural gas wastes are also pending in
some states, and these various initiatives could have a similar impact on us.

   The Clean Water Act imposes restrictions and controls on the discharge of
oil and natural gas wastes and other forms of pollutants into waters of the
United States. Federal law also imposes strict liability on owners of
facilities for consequences of an oil spill where the spill is in navigable
waters or along shorelines. These laws impose penalties for unauthorized
discharges and substantial liability for costs of removal and damages resulting
from an unauthorized discharge. State laws for the control of water pollution
provide similar penalties and liabilities. The cost of compliance with water
pollution laws has not historically been material to our operations. There can
be no assurance that changes in federal, state or local water pollution laws
and programs will not materially adversely affect our operations in the future.

                                       43
<PAGE>

   Our management believes that we are in substantial compliance with current
environmental laws and regulations that affect us and that continued compliance
with these requirements will not have a material adverse impact on us.

Legal Proceedings

   From time to time, we may be a party to various legal proceedings. We
currently are not a party to any material litigation.

Employees

   At March 31, 2000, we had 40 full-time employees. We believe that our
relationships with our employees are satisfactory. None of our employees is
covered by a collective bargaining agreement. From time to time, we use the
services of independent consultants and contractors to perform various
professional services, particularly in the areas of construction, design, well-
site surveillance, permitting and environmental assessment.

Employment Contracts

   Floyd C. Wilson and 3TEC entered into an employment agreement commencing on
April 15, 2000, and terminating on December 31, 2002, pursuant to which Mr.
Wilson will serve as our Chief Executive Officer with an annual base salary of
$325,000. Our board of directors may terminate Mr. Wilson's employment under
the employment agreement with or without Cause. "Cause" is defined as (a) the
inability, despite any reasonable accommodation required by law, due to bodily
injury or disease or any other physical or mental incapacity, to perform the
services provided for under the employment agreement for a period of 120 days
in the aggregate, within any given period of 180 consecutive days during the
term of the employment agreement, in addition to any statutorily required leave
of absence, (b) conduct that constitutes fraud, dishonesty, theft, or a
criminal act involving moral turpitude, in each case only if it materially
affects his ability to perform the duties and responsibilities of his position
or has a material adverse effect on us, (c) commission of a material act of

                                       46
<PAGE>

fraud against us, (d) embezzlement of funds or misappropriation of other
property from us; or (e) failure to observe or perform his material duties and
obligations as our employee or a material breach of the employment agreement,
after 30 days advance written notice of such failure or breach which has not
been cured. If Mr. Wilson is terminated by us without Cause, we are required to
pay him a severance payment equal to the salary payable to him over the
remaining term of his agreement.

   The employment agreement contains certain noncompete, confidentiality and
noninterference provisions. For example, during the term of the employment
agreement Mr. Wilson may not be employed or render advisory, consulting or
other services in connection with any business enterprise or person that is
engaged in leasing, acquiring, exploring, producing, gathering or marketing
hydrocarbons and related products. Further, during the term of the employment
agreement Mr. Wilson may not be financially interested, invest or engage in any
business that is engaged in leasing, acquiring, exploring, producing, gathering
or marketing hydrocarbons and related products, with certain limited
exceptions. The agreement also provides that Mr. Wilson will not disclose or
make use of any trade secrets or confidential or proprietary information
pertaining to us in a way that is materially detrimental to us. Mr. Wilson is
also prohibited during the two-year period of his employment agreement or the
period for which Mr. Wilson is employed by us, whichever is longer, and for a
six-month period commencing upon the termination of such longer period from
soliciting any of our employees or any other person who is under contract with
or rendering services to us to (a) terminate his or her employment with us, (b)
refrain from extending or renewing his or her employment with us, (c) refrain
from rendering services to or for us, (d) become employed by or to enter into
contractual relations with any persons other than us, or (e) enter into a
relationship with any of our competitors.

   R. A. Walker and 3TEC entered into an employment agreement commencing on May
1, 2000, and terminating on December 31, 2002, pursuant to which Mr. Walker
will serve as our President and Chief Financial Officer with an annual base
salary of $300,000. The agreement also provides that Mr. Walker will be granted
options giving him the right to purchase 500,000 shares of our common stock,
one-half of which shall be immediately vested with the remaining portion to
vest equally on each of the next three anniversary dates of his employment. The
exercise price under the option granted to Mr. Walker is the fair market value
of shares of our common stock on the date of grant. We may terminate Mr.
Walker's employment under the employment agreement with or without Cause.
"Cause" is defined similarly to the definition of "Cause" contained in Mr.
Wilson's employment agreement. If Mr. Walker is terminated by 3TEC without
Cause, the Company is required to pay him a severance payment equal to two
times his base salary. Mr. Walker's employment agreement also contains
noncompete, confidentiality and noninterference provisions that are similar in
scope and term to the noncompete, confidentiality and noninterference
provisions in Mr. Wilson's employment agreement, described above.

   Stephen W. Herod executed an employment agreement with us with an effective
date of July 1, 1997, and extending through June 30, 2000, with automatic one-
year extensions upon each anniversary date of the employment agreement
thereafter unless either party gives at least 30 days notice of termination.
The employment agreement is terminable by us before expiration of the term if
such termination is for cause (as specified in the employment agreement). The
executive employment agreement provides for an annual salary of not less than
the base salary of $100,000, which amount may be adjusted from time to time by
the board of directors upon the recommendation of the compensation committee of
the board of directors. It also provides for fringe benefits in accordance with
our policies adopted from time to time for salaried executive employees holding
comparable positions.

                          DESCRIPTION OF CAPITAL STOCK

   The description of our capital stock below is only a summary and is not

certificate of incorporation and bylaws, which have been filed with the
Securities and Exchange Commission.

   Our authorized capital stock consists of 60,000,000 shares of common stock,
par value $0.02 per share, and 20,000,000 shares of preferred stock, par value

Series B Preferred Stock, 2,300,000 shares of Series C Preferred Stock and

   As of March 31, 2000, 6,422,181 shares of common stock, 266,667 shares of
Series B Preferred Stock, 2,167,156 shares of Series C Preferred Stock and

Common Stock

   Subject to the preferential rights of any outstanding series of preferred
stock, the holders of our common stock are entitled to one vote per share on
all matters voted on by stockholders, including in the election of directors.
Our certificate of incorporation does not provide for cumulative voting in the
election of directors or grant preemptive rights with respect to future
issuances of our common stock. We may in the future, however, enter into
contracts with stockholders to grant holders preemptive rights.

   Subject to any preferential rights of any series of preferred stock
outstanding, the holders of our common stock are entitled to dividends, if any,
as may be declared from time to time by our board from funds legally available
to pay dividends and, upon liquidation, are entitled to receive a pro rata
share of all of our assets that are available for distribution to stockholders.
All our common stock is fully paid and nonassessable.

Transfer Agent

   The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company. The phone number for American Stock Transfer & Trust
Company is (718) 921-8200.

Preferred Stock

   Series B Convertible Preferred Stock. The Series B Preferred Stock has a
redemption value of $7.50 per share. Dividends are payable when, as and if
authorized and declared by the board of directors, and we are not restricted
from declaring and paying dividends on any shares of preferred stock.

   Until December 31, 2002, holders of Series B Preferred Stock have the right,
at any time, to convert one share of Series B Preferred Stock into one third of
a share of common stock or into as many as a total of 444,444 shares of common
stock, contingent upon the results of drilling and leasing activity on 3TEC's
mineral acreage in south Louisiana. At any time after December 31, 2002, we
have the right, upon not less than 30 days nor more than 90 days written
notice, to redeem any or all shares of Series B Preferred Stock for $7.50 per
share plus any accrued and unpaid dividends. The holders of the Series B
Preferred Stock do not have the right to require us to redeem the Series B
Preferred Stock and do not have voting rights except those required by law. In
the event of our liquidation, dissolution or winding-up, the holders of Series
B Preferred Stock are entitled to receive distributions of $7.50 per share plus
any accrued but unpaid dividends before any holders of common stock or junior
preferred stock receive any distributions.

   In the event of any stock split, reverse stock split, stock dividend,
recapitalization or similar transaction, appropriate adjustments will be made
to the Series B Preferred Stock to maintain the rate of conversion, redemption,
or distributions upon liquidation.

                                       50
<PAGE>

   Series C Convertible Preferred Stock. The Series C Preferred Stock has a
redemption value of $5.00 per share and pays dividends at an amount per share
of $0.50 per annum, payable semi-annually on March 31 and September 30 of each
year.

   Holders of Series C Preferred Stock have the right, at any time, to convert
one share of Series C Preferred Stock into one third of a share of common
stock. We have the right, upon not less than 30 nor more than 90 days written
notice, to redeem any or all shares of Series C Preferred Stock for $5.00 per
share plus any accrued and unpaid dividends. The holders of the Series C
Preferred Stock do not have the right to require us to redeem the Series C
Preferred Stock. In the event of our liquidation, dissolution or winding-up,
the holders of Series C Preferred Stock are entitled to receive distributions
of $5.00 per share plus any accrued but unpaid dividends before any holders of
common stock or junior preferred stock receive any distributions.

   In the event of any stock split, reverse stock split, stock dividend,
recapitalization or similar transaction, appropriate adjustments will be made
to the Series C Preferred Stock to maintain the rate of conversion, redemption,
or distributions upon liquidation.

   Except as required by law, the holders of the Series C Preferred Stock are
only entitled to vote upon those amendments, alterations or repeals of
provisions of our Certificate of Incorporation that adversely affect their
rights and preferences as preferred stockholders. The Series C Preferred Stock
ranks in parity with the Series B and Series D Preferred Stock with regard to
preferences upon our liquidation, dissolution or winding up.

   No dividends may be authorized or paid or set apart for payment or other
distribution of cash or other property authorized or made directly or
indirectly by us with respect to any shares of our common stock or any junior
preferred stock unless the full cumulative dividends on all outstanding shares
of Series C Preferred Stock shall have been paid or such dividends have been
authorized and set apart for payment with respect to the Series C Preferred
Stock.

   We have made application requesting that the Series C Preferred Stock be
approved for listing on the Nasdaq SmallCap Stock Market.

   Series D Convertible Preferred Stock. In connection with the acquisition of
Magellan, 617,008 shares of Series D Preferred Stock, par value $0.02 per
share, were issued with a redemption value of $24.00 per share. While the per
share redemption and dividends amounts vary, the rights as to dividends and
liquidation payments of all outstanding issues of Preferred Stock are equal.
Shares of Series D Preferred Stock earn dividends at 5% per annum cumulative,
payable semi-annually on March 31 and September 30 of each year, when, as and
if authorized and declared by the board of directors. For a period of three
years from the closing date of the Magellan transaction, we may pay the
dividends at our option in cash or in additional shares of Series D Preferred
Stock.

   Holders of Series D Preferred Stock have the right to convert one share of
Series D Preferred Stock into one share of common stock. Upon thirty days
written notice, we have the right to redeem any or all shares of Series D
Preferred Stock for $24.00 per share plus any accrued and unpaid dividends.
Holders of the Series D Preferred Stock have no right to require us to redeem
the Series D Preferred Stock.

   In the event of our liquidation, dissolution, winding-up or merger, the
holders of Series D Preferred Stock are entitled to receive distributions of
$24.00 per share of Series D Preferred Stock plus any accrued but unpaid
dividends before any holders of common stock or junior preferred stock receive
any distributions.

   In the event of any stock split, reverse stock split, stock dividend,
recapitalization or similar transaction, appropriate adjustments will be made
to the Series D Preferred Stock to maintain the rate of conversion, redemption,
or distributions upon liquidation existing at the date of any such event.

   A majority of the holders of Series D Preferred Stock must consent to
certain actions by us, including any which (a) adversely alters or changes the
rights, preferences or privileges of the Series D Preferred Stock

                                       51
<PAGE>

holders by merger, consolidation or otherwise, (b) increases the authorized
number of shares of Series D Preferred Stock, or (c) authorizes or issues any
securities with rights senior to the Series D Preferred Stock. Other than these
described consents or as required by law or any provision of our Certificate of
Incorporation, the holders of Series D Preferred Stock have no voting rights.

   Additional shares of preferred stock may be issued from time to time in one
or more series without shareholder approval. With regard to the preferred
stock, the board of directors may determine:

  . the preferences;

  . conversion or other rights;

  . voting powers;

  . restrictions;

  . limitations on dividends; and

  . qualifications and terms and conditions of redemption.

   As a result, without shareholder approval, our board of directors could
authorize the issuance of additional shares of preferred stock with voting,
conversion and other rights that could dilute the voting power and other rights
of the holders of common stock.

Shareholders Agreement

   Pursuant to a Shareholders Agreement dated August 27, 1999, among us and
certain of our stockholders collectively owning approximately 69% of our
outstanding common stock as of March 31, 2000, before giving effect to this
offering (or approximately 35% after giving effect) and before the conversion
of our convertible subordinated notes and the exercise of the related warrants,
these stockholders have agreed to vote in favor of the election of, and cause
their affiliates to vote in favor of the election of, three members of the
board of directors designated by W/E LLC and two members of the board of
directors designated by the remaining stockholders, Kaiser-Francis Oil Company,
C. J. Lett, III, Weskids, L.P. and Alvin V. Shoemaker (the "Remaining
Stockholders"). Accordingly, the parties to the agreement currently have the
ability to control the election of all of the members of our board of
directors. As the ownership percentage of W/E LLC and the Remaining
Stockholders decreases, the number of directors they may designate declines and
ultimately, when that percentage falls below 5%, their right to designate board
members pursuant to this agreement shall terminate. When the ownership
percentage of both W/E LLC and the Remaining Stockholders falls below 5%, the
agreement automatically terminates. As of March 31, 2000, W/E LLC and its
affiliates, including EnCap, own approximately 37% of our outstanding common
stock.

Registration Rights

   Pursuant to a Registration Rights Agreement dated August 27, 1999, as
amended, we granted demand registration rights to W/E LLC, Shoemaker Family
Partners, LP, Shoeinvest II, LP, and Prudential, providing these stockholders
with the right to require us to use our best efforts to cause registration and
sale in a public offering of all or a portion of the shares held by the
stockholder or stockholders demanding the registration. In addition, subject to
the underwriters discretion to limit the number of shares of selling
stockholders to be included in an offering, we granted piggy-back registration
rights to these stockholders and to Kaiser-Francis Oil Company, C.J. Lett, III,
Weskids, L.P., and Alvin V. Shoemaker in the event that we propose to file, on
our own behalf, a registration statement on Form S-1, S-2, S-3 or other similar
forms available. All of these stockholders have agreed to waive their right to
sell shares in this offering.

   Pursuant to a Registration Rights Agreements dated February 2, 2000, we
granted demand registration rights to Pel-Tex Partners, L.L.C. and EnCap and
certain of EnCap's affiliates providing these stockholders with the right to
use our best efforts to cause registration and sale in a public offering of all
or a portion of the

                                       52
<PAGE>

shares held by the stockholder or stockholders demanding the registration. In
addition, subject to the underwriters' discretion to limit the number of shares
of selling stockholders to be included in an offering, we granted piggy-back
registration rights to these stockholders and to Earl P. Burke, Jr. Family
Limited Partnership and Joint Energy Department Investments Limited Partnership
in the event we propose to file, on our own behalf, a registration statement on
Form S-1, S-2, S-3 or other similar forms available. All of these stockholders
have agreed to waive their right to sell shares in this offering.

Business Combinations under Delaware Law

   We are a Delaware corporation and are governed by Section 203 of the
Delaware General Corporation Law. Section 203 prevents an interested
shareholder, which is a person who owns 15% or more of our outstanding voting
stock, from engaging in business combinations with us for three years following
the time the person becomes an interested shareholder. These restrictions do
not apply if:

  . before the person becomes an interested shareholder, our board of
    directors approves the transaction in which the person becomes an
    interested shareholder or the business combination;

  . upon completion of the transaction that results in the person becoming an
    interested shareholder, the interested shareholder owns at least 85% of
    our outstanding voting stock at the time the transaction began, excluding
    for purposes of determining the number of shares outstanding those shares
    owned by persons who are directors and also officers and employee stock
    plans in which employee participants do not have the right to determine
    confidentially whether shares held subject to the plan will be tendered
    in a tender or exchange offer; or

  . following the transaction in which the person became an interested
    shareholder, the business combination is approved by our board of
    directors and authorized at an annual or special meeting of our
    stockholders, and not by written consent, by the affirmative vote of at
    least two-thirds of our outstanding voting stock not owned by the
    interested shareholder.

   In addition, the law does not apply to interested stockholders who became
interested stockholders before the common stock was listed on the Nasdaq
SmallCap Market.

   Delaware law defines the term "business combination" to encompass a wide
variety of transactions with, or caused by, an interested shareholder,
including mergers, asset sales and other transactions in which the interested
shareholder receives or could receive a benefit on other than a pro rata basis
with other stockholders. This law could have an anti-takeover effect with
respect to transactions not approved in advance by our board of directors,
including discouraging takeover attempts that might result in a premium over
the market price for the shares of the common stock.

Limitation of Liability and Indemnification of Officers and Directors

   Limitation of Liability. Delaware law authorizes corporations to limit or
eliminate the personal liability of their officers and directors to them and
their stockholders for monetary damages for breach of officers' and directors'
fiduciary duty of care. The duty of care requires that, when acting on behalf
of the corporation, officers and directors must exercise an informed business
judgment based on all material information reasonably available to them. Absent
the limitations authorized by Delaware law, officers and 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.

   Our Certificate of Incorporation limits the liability of our directors to us
and to our stockholders to the fullest extent permitted by Delaware law.
Specifically, our directors will not be personally liable for monetary damages
for breach of their fiduciary duty in such capacity, except for liability:

  . for any breach of the director's duty of loyalty to us or our
    stockholders;

                                       53
<PAGE>

  . for acts or omissions not in good faith or which involve intentional
    misconduct or a knowing violation of law;

  . for unlawful payments of dividends or unlawful stock repurchases or
    redemptions as provided in Section 174 of the Delaware General
    Corporation Law; or

  . for any transaction from which the director derived an improper personal
    benefit.

   Indemnification. Delaware law also authorizes corporations to indemnify its
officers, directors, employees and agents for liabilities, other than
liabilities to the corporation, arising because that individual was an officer,
director, employee or agent of the corporation so long as the individual acted
in good faith and in a manner he or she reasonably believed to be in the best
interests of the corporation and not unlawful.

   Our bylaws provide that our officers and directors will be indemnified by us
for liabilities arising because such individual was one of our officers or
directors to the fullest extent permitted by Delaware law. Our bylaws also
provide that we may, by action of our board of directors, provide similar
indemnification to our employees and agents.

   These provisions in our Certificate of Incorporation and bylaws may reduce
the likelihood of derivative litigation against our officers and directors and
may discourage or deter our stockholders or management from bringing a lawsuit
against our officers and directors for breach of their duty of care, even
though the action, if successful, might otherwise have benefited us and our
stockholders.

   These provisions in our Certificate of Incorporation and bylaws do not alter
the liability of our officers and directors under federal securities laws and
do not affect the right to sue under federal securities laws for violations
thereof.

                         DESCRIPTION OF CREDIT FACILITY

   Concurrent with the acquisition of the Floyd Oil Properties, we entered into
a $250 million credit facility with Bank One, Texas, N.A., as agent, and Union
Bank of California, N.A., Wells Fargo Bank, CIBC, Inc., and The Bank of Nova
Scotia as participating lenders. Our borrowing base has been initially set at
$95 million with $83.5 million outstanding as of March 31, 2000. The borrowing
base will be redetermined semi-annually on May 1 and November 1 of each year.
Interest under the facility accrues at a rate calculated at our option as
either the bank's prime rate plus 25 basis points or LIBOR plus basis points
increasing from a low of 125 to a high of 187.5 as loans outstanding increase
as a percentage of the borrowing base. As of March 31, 2000, we are paying
7.875% per annum interest on $82.5 million and 7.88% per annum interest on $1.0
million of the principal balance of this facility. The loan matures on November
30, 2002. Prior to maturity, no payments of principal are required so long as
the borrowing base exceeds the loan balance. The borrowings under the facility
are secured by substantially all our properties.

   In connection with our pending acquisition of the CWR Properties we have
begun negotiations with the lenders participating in our credit facility to
increase the amount of availability under the borrowing base by an amount which
would enable us to borrow substantially all of the purchase price of the CWR
Properties. These negotiations are ongoing and the lenders have indicated a
preliminary willingness to increase our available borrowing capacity by an
amount which would enable us to borrow substantially all of the purchase price
of the CWR Properties. As indicated elsewhere in this Prospectus, the net
proceeds of this offering will be used principally to repay indebtedness
outstanding under this credit facility.

   In connection with our existing credit facility, we are required to adhere
to certain affirmative and negative covenants including but not limited to:

  . Use of all proceeds from sales of oil and natural gas properties for the
    repayment of the outstanding debt.

  . We may not allow the ratio of our current assets to our defined current
    liabilities to be less than 1:1 at the end of any fiscal quarter.

  . We may not allow the defined minimum interest coverage ratio to be less
    than 2.5:1 at the end of any fiscal quarter prior to the quarter ending
    September 30, 2000, and each four quarter period thereafter.

  . We may not declare or pay any cash dividend; purchase, redeem or
    otherwise acquire for value any of our outstanding stock; return capital
    to stockholders; or make any distribution of our assets to stockholders;
    except for dividends on and redemption of Series C Preferred Stock under
    certain circumstances.

  . We have agreed that we will not enter into any hedging transactions
    except with the lenders' consent and for certain pre-approved hedging
    activities in connection with oil and natural gas prices.

   Events of default under the facility include a final judgment or order in
the excess of $1 million, a change of control of 3TEC or Floyd C. Wilson
ceasing to act as our Chief Executive Officer.

</TABLE>

   The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares included in this
offering are subject to approval of legal matters by their counsel and to
customary conditions, including the effectiveness of the registration
statement, the continuing correctness of our representations to them, the
receipt of "comfort letters" from our accountants and no occurrence of an event
that would have a material adverse effect on our business. The underwriters are
obligated to purchase all the shares, other than those covered by the over-
allotment option described below, if they purchase any of the shares.

   We have granted to the underwriters an option, exercisable for 30 days from
the date of the underwriting agreement, to purchase up to 937,500 additional
shares at the public offering price less the underwriting fees. The
underwriters may exercise this option solely to cover over-allotments, if any,
made in connection with this offering. To the extent that the underwriters
exercise the option, each underwriter will become obligated, subject to
conditions, to purchase a number of additional shares approximately
proportionate to such underwriter's initial purchase commitment.

   The underwriters propose initially to offer some of the shares directly to
the public at the public offering price set forth on the cover page of this
prospectus and some of the shares to dealers at the public offering price less
a concession not in excess of $   per share. The underwriters may allow, and
such dealers may re-allow, a concession not in excess of $   per share on sales
to other dealers. After the offering of the shares to the public, the
representatives of the underwriters may change the public offering price and
such concessions.

   In order to facilitate the offering of our common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
market price of our common stock. Specifically, the underwriters may over-allot
shares of our common stock in connection with this offering, thereby creating a
short position in our common stock for their own account. In addition, to cover
over-allotments or to stabilize the market price of our common stock, the
underwriters may bid for, and purchase, shares of our common stock in the open
market. The representatives, on behalf of the underwriters, also may reclaim
selling concessions allowed to an underwriter or dealer if the underwriting
syndicate repurchases shares distributed by that underwriter or dealer. Any of
these activities may maintain the market price of our common stock at a level
above that which might otherwise prevail in the open market. These transactions
may be made in the over-the-counter market or otherwise. The underwriters are
not required to engage in these activities and, if begun, may end any of these
activities at any time.

   Rules of the SEC may limit the ability of the underwriters to bid for or
purchase shares before the distribution of the shares is completed. However,
the underwriters may engage in the following activities in accordance with the
rules:

                                       56
<PAGE>

  . Stabilizing transactions--The representatives may make bids or purchases
    for the purpose of pegging, fixing or maintaining the price of the
    shares, so long as stabilizing bids do not exceed a specified maximum.

  . Over-allotments and syndicate covering transactions--The underwriters may
    create a short position in the shares by selling more shares than are set
    forth on the cover page of this prospectus. If a short position is
    created in connection with the offering, the representatives may engage
    in syndicate covering transactions by purchasing shares in the open
    market. The representatives may also elect to reduce any short position
    by exercising all or part of the over-allotment option.

  . Penalty bids--If the representatives purchase shares in the open market
    in a stabilizing transaction or syndicate covering transaction, they may
    reclaim a selling concession from the underwriters and selling group
    members who sold those shares as part of the offering.

   Stabilization and syndicate covering transactions may cause the price of the
shares to be higher than they would be in the absence of such transactions. The
imposition of a penalty bid might also have an effect on the price of the
shares if it discourages resales of the shares.

   Prior to the pricing of the common stock subject to this offering and until
the time when a stabilizing bid may have been made, some or all of the
underwriters may make bids for or purchases of shares of our common stock,
subject to certain restrictions, known as passive market making activity.

   Neither we nor the underwriters make any representation or prediction as to
the effect that the transactions described above may have on the price of the
shares. These transactions may occur on the Nasdaq or otherwise. If such
transactions are commenced, they may be discontinued without notice at any
time.

   We have agreed to indemnify the underwriters against a number of
liabilities, including liabilities under the Securities Act, or to contribute
to payments the underwriters may be required to make as a result of these
liabilities.

   The following table summarizes the compensation and estimated expenses we
will pay.

of natural gas and oil regardless of whether such acreage contains proved
reserves.

   Working interest. The operating interest that gives the owner the right to
drill, produce and conduct operating activities on the property and receive a
share of production.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
3TEC Energy Corporation:

   We have audited the accompanying consolidated balance sheets of 3TEC Energy
Corporation (formerly Middle Bay Oil Company, Inc.) and subsidiaries as of
December 31, 1999 and December 31, 1998 and the related consolidated statements
of operations, changes in stockholders' equity, and cash flows for each of the
years then ended. 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 3TEC Energy
Corporation and subsidiaries as of December 31, 1999 and 1998, and the results
of their operations and their cash flows for each of the years then ended in
conformity with generally accepted accounting principles.

                           December 31, 1999 and 1998

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Organization

   3TEC Energy Corporation (the Company), formerly Middle Bay Oil Company,
Inc., was incorporated under the laws of the state of Alabama on November 20,
1992. The Company was reincorporated in Delaware on December 7, 1999 and
changed its name to 3TEC Energy Corporation. The reincorporation and name
change were part of a series of transactions related to a securities purchase
agreement that closed on August 27, 1999 between the Company and W/E Energy
Company, LLC ("W/E LLC") formerly known as 3TEC Energy Company, LLC, whereby
the Company received $21.4 million in cash and oil and natural gas properties
for the sale of common stock, warrants and debt securities (See Note 3).

   Effective March 27, 1998, the Company acquired 79.2% of Enex Resources
Corporation ("Enex") and over a three week period ending December 23, 1998, the
Company acquired an additional 0.80% of Enex for a total 80% of Enex. Effective
April 16, 1998, the Company acquired the oil and gas assets of Service Drilling
Co., LLC ("Service Drilling"). Effective October 1, 1998, the Company acquired
100% of Enex Consolidated Partners, L.P. ("Enex Partnership"), a limited
partnership of which Enex owned greater than a 50% interest. Effective November
23, 1999, the Company acquired oil and natural gas properties and interests
managed by Floyd Oil Company ("Floyd Oil Company ") from a group of private
sellers. The Company is engaged in the acquisition, development, production and
exploration of oil and natural gas in the contiguous United States. The Company
considers its business to be a single operating segment.

 Significant Accounting Policies

   The Company's accounting policies reflect industry standards and conform to
generally accepted accounting principles. The more significant of such policies
are described below.

 Principles of Consolidation

   The consolidated financial statements include the accounts of the Company,
its wholly-owned subsidiaries and Enex, an 80% owned subsidiary. The equity of
the minority interests in Enex is shown in the consolidated financial
statements as "minority interest". All significant intercompany balances and
transactions have been eliminated in consolidation.

 Cash and Cash Equivalents

   For purposes of the statements of cash flows, the Company classifies all
cash investments with original maturities of three months or less as cash.

 Oil and Gas Property

   The Company follows the successful efforts method of accounting for oil and
natural gas properties, and accordingly, capitalizes all direct costs incurred
in connection with the acquisition, drilling and development of productive oil
and natural gas properties. Costs associated with unsuccessful exploration are
charged to expense currently. Geological and geophysical costs and costs of
carrying and retaining unevaluated properties are charged to expense.
Depreciation, depletion and amortization of capitalized costs are computed
separately for each field based on the unit-of-production method using only
proved oil and natural gas reserves. In arriving at such rates, commercially
recoverable reserves have been estimated by independent petroleum engineering
firms. The Company reviews its undeveloped properties continually and charges
them to expense on a property by

                                      F-7
<PAGE>

                   3TEC ENERGY CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                          December 31, 1999 and 1998

property basis when it is determined that they have been condemned by dry
holes, or have otherwise diminished in value. The Company recorded impairments
of $1.5 million on its undeveloped properties, principally fee minerals and
non-producing leasehold costs, for the year ended December 31, 1999. Gains and
losses are recorded on sales of interests in proved properties and on sales of
entire interests in unproved properties. For the years ended December 31, 1999
and 1998, the Company realized gains on sales of properties of $1.0 million
and $2.0 million, respectively.

   Proved oil and natural gas reserves are the estimated quantities of oil,
natural gas and natural gas liquids which are expected to be recoverable in
future years from known reservoirs under existing economic and operating
conditions. Reservoirs are considered proved if economic producibility is
supported by either actual production or conclusive formation tests.

   The Company reviews long-lived assets for impairment when events or changes
in circumstances indicate that the carrying value of such an asset may not be
recoverable. This review consists of a comparison of the carrying value of the
asset to the asset's expected future undiscounted cash flows. Estimates of
expected future cash flows represent management's best estimate based on
reasonable and supportable assumptions and projections. If the expected future
cash flows, assuming escalated prices, are less than the carrying value of the
asset, an impairment exists and is measured as the excess of the carrying
value over the estimated fair value of the asset. The Company estimates
discounted future net cash flows to determine fair value. Any impairment
provisions recognized are permanent and may not be restored in the future. For
the years ended December 31, 1999 and 1998, the Company's proved properties
were assessed for impairment on an individual field basis and the Company
recorded impairment provisions on certain producing properties of $1.0 million
and $4.1 million, respectively.

 Site Restoration, Dismantlement and Abandonment Costs

   Site restoration, dismantlement and abandonment costs (P&A costs) are
common in the oil and natural gas industry. P&A costs are costs associated
with removing the facilities and equipment required to operate a well and
restoring the well site to specified conditions. P&A costs are incurred when
the oil and natural gas reserves of a well or wells are depleted or when
production drops to the point that it is no longer economically feasible to
produce.

   The Company, in conjunction with its independent engineers and the
operators of the wells, continually reviews its working interests with respect
to potential P&A costs. Estimated P&A costs (net of estimated salvage value)
are amortized through depletion using the unit-of-production method.

   As of December 31, 1999 and 1998, the Company's estimated P&A costs were
approximately $495,000.

 Other Property and Equipment

   Other property and equipment are stated at cost and depreciation is
computed on the straight line method over estimated lives ranging from five to
seven years. Additions and betterments which provide benefits to several
periods are capitalized.

 Environmental Liabilities

   Environmental expenditures that relate to current or future revenues are
expensed or capitalized as appropriate. Expenditures that relate to an
existing condition caused by past operations, and do not contribute to current
or future revenue generation, are expensed. Liabilities are recorded when
environmental assessments

                                      F-8
<PAGE>

                    3TEC ENERGY CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                           December 31, 1999 and 1998

and/or clean-ups are probable, and the costs can be reasonably estimated.
Generally, the timing of these accruals coincides with the Company's commitment
to a formal plan of action.

   As of December 31, 1999, the Company had accrued estimated environmental
costs of approximately $250,000.

 Revenue

   Oil and natural gas revenues are recorded using the sales method, whereby
the Company recognizes revenues based on the amount of oil and natural gas sold
to purchasers on its behalf. At December 31, 1999 and 1998, the Company's net
imbalance position was immaterial.

 Hedging

   The Company periodically enters into derivative contracts to hedge the risk
of future oil and natural gas price fluctuations. Such contracts may either fix
or support oil and natural gas prices or limit the impact of price fluctuations
with respect to the Company's sales of oil and natural gas.

   The Company uses the hedge or deferral method of accounting for derivative
contracts and, as a result, gains and losses on commodity derivative financial
instruments are generally offset by similar changes in realized prices of
commodities. In order to qualify as hedges, price movements in the underlying
commodity derivative must be highly correlated with the hedged commodity. Gains
and losses on such hedging activities are recognized in oil and natural gas
production revenues when hedged production is sold. If a derivative ceases to
qualify as a hedge, changes in fair value of the derivative instrument are
recognized in earnings currently.

 Income Taxes

   The Company uses the asset and liability method of accounting for income
taxes under which deferred tax assets and liabilities are determined by
applying enacted statutory tax rates applicable to future years to the
difference between the financial statement and tax basis of assets and
liabilities. The effect on deferred tax assets and liabilities of a change in
tax rates is recognized as part of the provision for income taxes in the period
that includes the enactment date.

 Stock Based Compensation

   The Company accounts for stock-based compensation under the intrinsic value
method. Under this method, the Company records no compensation expense for
stock options granted when the exercise price of options granted is equal to or
greater than the fair market value of the Company's common stock on the date of
grant.

 Earnings Per Share

   Basic earnings and loss per common share are based on the weighted average
shares outstanding without any dilutive effects considered. Diluted earnings
and loss per share reflects dilution from all potential common shares,
including options, warrants and convertible preferred stock and notes. Diluted
loss per share does not include the effect of any potential common shares if
the effect would be to decrease the loss per share.

   All share and per share amounts have been retroactively adjusted for a one-
for-three reverse split that was approved on January 14, 2000 (See Note 14).

                          December 31, 1999 and 1998


 Concentrations of Market Risk

   The future results of the Company will be affected by the market prices of
oil and natural gas. The availability of a ready market for oil and natural
gas in the future will depend on numerous factors beyond the control of the
Company, including weather, production of other oil and natural gas, imports,
marketing of competitive fuels, proximity and capacity of oil and natural gas
pipelines and other transportation facilities, any oversupply or undersupply
of oil and natural gas, the regulatory environment, and other regional and
political events, none of which can be predicted with certainty.

 Concentrations of Credit Risk

   Financial instruments which subject the Company to concentrations of credit
risk consist primarily of cash and accounts receivable. The Company places its
cash investments with high credit qualified financial institutions. Risk with
respect to receivables is concentrated primarily in the current production
revenue receivable from multiple oil and natural gas producers, both major and
independent, and is typical in the industry. No single customer accounted for
greater than 10% of the Company's total oil and natural gas sales for the
years ended December 31, 1999 and 1998.

 Accounting Pronouncements

   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 standardizes the accounting
for and disclosures of derivative instruments, including certain derivative
instruments embedded in other contracts. The statement is effective for
financial statements for periods beginning after June 15, 2000. The Company
has not yet determined the impact of the Statement on its financial condition
or results of operations.

 Use of Estimates

   Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities to prepare the financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.

 Reclassifications

   Certain reclassifications of prior period amounts have been made to conform
to the current presentation.

(2) ACQUISITIONS

   On March 27, 1998, the Company acquired 1,064,432 common shares,
approximately 79.2%, of Enex for $15.9 million. The Company purchased the
common shares of Enex through a cash tender offer that commenced February 19,
1998 (the "Enex Acquisition"). The Company also incurred approximately $60,934
in legal, accounting and printing expenses and issued 11,275 shares of Company
common stock for finders fees to unrelated third parties. At the time, Enex
was general partner of the Enex Partnership, a New Jersey limited partnership
whose principal business is oil and natural gas exploration and production.
Enex's general partner interest in the Enex Partnership was 4.1%. Enex also
owned an approximate 56.2% limited partner interest in the Enex Partnership.

   As part of the Enex Acquisition, the Company entered into a consulting
agreement, effective April 15, 1998, with the former president of Enex that
provides for monthly payments of $20,000 until expiration of the

                                     F-10

                           December 31, 1999 and 1998

agreement on May 18, 2002. The monthly payments serve as consideration for
consulting, a covenant not to compete and a preferential right to purchase
certain oil and natural gas acquisitions which the former president controls or
proposes to acquire during the term of the agreement. The Company will
reimburse the former president each month for reasonable and necessary business
expenses incurred in connection with the performance of consulting services.
The agreement survives the former president and his spouse and is
nonassignable. At December 31, 1999 and 1998, the present value of the
agreement, applying a 10% discount, was approximately $497,627 and $677,949,
respectively. The long-term portion of the agreement is classified as other
liabilities in the financial statements.

   The cost of acquiring 79.2% of Enex was allocated using the purchase method
of accounting to the consolidated assets and liabilities of Enex based on
estimates of the fair values with the remaining purchase price allocated to
proved oil and natural gas properties.

   The allocation of the purchase price is summarized as follows: (in
thousands)

</TABLE>

   Over a three-week period ending December 23, 1998, the Company acquired an
additional 0.80% (9,747 common shares) of Enex common stock for approximately
$68,000.

   On April 16, 1998, the Company acquired substantially all of the oil and
natural gas assets of Service Drilling, in exchange for 222,000 shares of
Company common stock and $6.5 million in cash for a total acquisition cost of
$10.0 million, before post-closing adjustments (the "Service Acquisition"). The
fair value of the securities issued in connection with the Service Acquisition
was calculated using the price of the Company's common stock at the time the
Service Acquisition was announced to the public and further adjusted for
tradability restrictions. An independent valuation firm determined the
tradability discount for the Company's common stock. The effective date of the
acquisition was March 1, 1998 and the cost was allocated using the purchase
method of accounting.

   On December 30, 1998, the Company completed the acquisition of the Enex
Partnership (the "Enex Partnership Acquisition"). The transaction consisted of
an exchange offer whereby the Company offered to exchange 2.086 shares of
Series C Preferred stock ("Series C") for each Enex Partnership unit (the
"Exchange Offer"). In connection with the Exchange Offer, the Company submitted
a proposal to investors in the Enex Partnership to amend the partnership
agreement to provide for the transfer of all of the assets and liabilities of
the Enex Partnership to the Company as of October 1, 1998 and dissolve the Enex
Partnership. The Exchange Offer was approved on December 30, 1998 and the
Company issued 2,177,481 Series C shares for 100% of the outstanding limited
partner units. At the close of the Exchange Offer, the Enex Partnership had
1,102,631 units outstanding. Enex was issued 1,293,522 Series C shares for its
56.2% ownership of the Enex Partnership. The remaining 883,959 Series C shares
were issued to the limited partners that elected to take Series C shares in
lieu of cash. In January 1999, certain dissenting limited partners were paid
$516,000 and other unitholders were paid $23,000 in lieu of fractional shares.
Because of the dissenting limited partners, Enex owns 59.4% of the Series C
shares, of which 20% (258,704 shares) are considered outstanding and held by
third parties in the consolidated financial statements at December 31, 1999 and
1998.

   The intent of the Exchange Offer was to acquire the 43.8% of the outstanding
limited partner units that the Company did not currently own. The tables below
present the consideration paid for 100% of the Enex Partnership and for the
43.8% of the Enex Partnership not owned by Enex.

   Since Enex is consolidated into the Company's financial statements, the
number of shares outstanding and the value of the shares outstanding
attributable to the 43.8% of the Enex Partnership not owned by Enex and the
minority interest owners of Enex (20%) is 1,142,663 and $5.7 million,
respectively. The cost of acquiring the outstanding limited partner units that
were not owned by Enex was approximately $6.7 million, consisting of the

   The Company's purchase price was allocated to the assets and liabilities
attributable to the 43.8% of the Enex Partnership based on estimates of the
fair values with the remaining purchase price allocated to proved oil and
natural gas properties. The registration costs of approximately $431,000
reduced the value of the Series C shares issued. Because the Enex Partnership
was consolidated in the financial statements of the Company as of the effective
date of October 1, 1998, the preliminary purchase price allocation below shows

   On November 23, 1999, the Company completed the acquisition of oil and
natural gas properties and interests, managed by Floyd Oil Company, owned by a
group of private sellers (the "Floyd Oil Acquisition") for $86.8 million in
cash and 503,426 shares of Company common stock. Prior to the acquisition,
there was no relationship between Floyd C. Wilson, President of the Company and
Floyd Oil Company. The effective date of the acquisition was January 1, 1999
and the cost was allocated using the purchase method of accounting. The total
purchase price of $90.2 million, considering post-closing adjustments and
transaction costs, was allocated principally to oil and natural gas properties.

</TABLE>

   Concurrent with the Floyd Oil Acquisition, the Company entered into a $250
million credit facility (the "Facility") with Bank One, Texas, NA as agent and
four other banks. The Company's borrowing base has been initially set at $95
million with $87.5 million outstanding at December 31, 1999. The borrowing
base will be redetermined semi-annually on May 1 and November 1. Interest
under the Facility accrues at a rate calculated at the Company's option as
either the bank's prime rate plus 25 basis points or LIBOR plus basis points
increasing from a low of 125 to a high of 187.5 as loans outstanding increase
as a percentage of the borrowing base. As of December 31, 1999, the Company
was paying 8.08% per annum interest on $82.5 million and 8.36% per annum
interest on $5 million of the principal balance of the Facility. The loan
matures on November 30, 2002. Prior to maturity, no payments of principal are
required so long as the borrowing base exceeds the loan balance. The
borrowings under the Facility are secured by substantially all of the
Company's oil and natural gas properties.

   The Facility requires an interest coverage ratio of two and a half to one
(2.5:1) determined on a quarterly basis prior to the quarter ending September
30, 2000 and each four quarter period thereafter, and a current ratio,
excluding current maturities of the Facility, of one to one (1:1) , determined
on a quarterly basis.

   The Facility also requires certain other affirmative and negative covenants
including, but not limited to:

  . Use of all proceeds from sales of oil and natural gas properties for the
    repayment of the outstanding debt.

(7) SENIOR SUBORDINATED CONVERTIBLE NOTES

   On August 27, 1999, senior subordinated convertible promissory notes (the
"Senior Notes") were sold to W/E LLC and affiliates of Alvin V. Shoemaker
("Shoemaker"), a former director and significant shareholder, for $10.7 million
and $150,000, respectively. On October 19, 1999, $2.4 million of Senior Notes
were sold to The Prudential Insurance Company of America ("Prudential"). The
Senior Notes bear interest at an annual rate of 9%. Interest is payable
beginning on December 31, 1999, every March 31, June 30, September 30 and
December 31, until maturity on August 27, 2004. The Company may defer payment
of fifty percent (50%) of the first eight quarterly interest payments. The
Senior Notes may be prepaid, without premium or penalty, in whole or in part,
at any time after August 27, 2001. The holders of the Senior Notes may convert
all or any portion of outstanding principal and accrued interest at any time
into shares of Company common stock at a conversion price of $9.00 per common
share, a total of 1,469,316 common shares. The conversion price may be adjusted
from time to time based on the occurrence of certain events. In the event of a
change in control, the entire outstanding principal balance and all accrued but
unpaid interest is immediately due and payable.

   The Senior Notes rank senior in right of payment to all Company notes and
indebtedness other than the Facility.

</TABLE>

   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
asset will not be realized. Management considers the scheduled reversal of
deferred tax liabilities, projected future taxable income, and tax planning
strategies in making this assessment. Based upon projections for future taxable
income over the periods in which the deferred tax assets are deductible and the
Section 382 limitation discussed below, management believes it is more likely
than not that the Company will realize the benefits of these deductible
differences, net of the existing valuation allowances at December 31, 1999 and
1998.

   The Enex Acquisition caused an ownership change pursuant to Section 382 in
March 1998. As a result of this ownership change, the Company's use of its net
operating loss carryforwards subsequent to that date will be limited. The Floyd
Oil Acquisition in November 1999 also caused an ownership change pursuant to
Section 382. As a result of this ownership change, the Company's use of its net
operating loss carryforwards subsequent to that date will be limited to
approximately $1.5 million per year.

   As of December 31, 1999, the Company had net operating loss carryforwards of
approximately $20 million, expiring beginning in 2009 through 2019.

(9) RETIREMENT PLAN AND EMPLOYEE INCENTIVE PLAN

   All of the employees of the Company are eligible to participate in a defined
contribution plan that provides for maximum discretionary employee
contributions of 15% of total wages paid to employees for the year and Company
contributions. No Company contributions were made to the plan for the years
ending December 31, 1999 and 1998.

                           December 31, 1999 and 1998


   In March 1995, the Board of Directors adopted an employee incentive
compensation plan (the "Plan") for the benefit of Company employees. The Plan
benefits were equal to one percent (1%) of the annual net profit from oil and
natural gas properties acquired or discovered on or after January 1, 1994 and
one percent (1%) of the annual sales proceeds from any oil and natural gas
properties sold on or after January 1, 1994. The Compensation Committee of the
Board of Directors had sole authority regarding the amount and timing of
payment of any Plan benefits to eligible employees.

   On August 27, 1999, the Company paid $274,625 to the eligible participants
in the Plan and terminated the Plan pursuant to the terms of the W/E LLC
agreement. The payment was equal to 100% of the Plan benefits through August
27, 1999. The entire amount of the payment, including associated taxes of
$17,902, was recognized during the year ended December 31, 1999. Prior to the
Compensation Committee's authorization, the Plan benefits were not accrued as
an expense in the financial statements because the likelihood that the
Compensation Committee would determine that the benefits would be payable to
eligible employees was less than probable.

(10) STOCK OPTION PLANS

   At December 31, 1999, the Company had two fixed stock option plans, the 1995
Stock Option and Stock Appreciation Rights Plan (the "1995 Plan") and the 1999
Stock Option Plan (the "1999 Plan"). As discussed in Note 1, for the years
ended December 31, 1999 and 1998, no compensation cost has been recognized,
relating to stock options issued, as the exercise price of each option equals
the market price of the Company's common stock on the date of grant. Had
compensation cost for the Company's 1995 Plan been determined based on the fair
value at the grant date for stock options granted for the years ending December
31, 1999 and 1998, the Company's net loss and loss per share would have been
increased to the pro forma amounts listed below (in thousands, except per share
amounts):

   The weighted average fair value of stock options granted during 1999 and
1998 was $2.40 and $8.91 per share, respectively. The fair value of each option
is estimated on the date of grant using the Black-Scholes option-pricing model
with the following assumptions used for the grants in 1999 and 1998; no
dividend yield; expected volatility of 77%; weighted average risk-free interest
rate of 4.78% and 4.93%, respectively; and an expected life of 3 years. At
December 31, 1999, the range of exercise prices and weighted average remaining
contractual life of options outstanding was $4.50 to $23.25 and 2.81 years,
respectively.

   At December 31, 1999 there were 157,300 and 500,000 shares of common stock
available for grant under the 1995 and 1999 Plans, respectively. All of the
options granted under the 1995 Plan expire five (5) years from the date of
grant if not exercised and are 100% vested. As of December 31, 1999, no options
have been issued under the 1999 Plan. The 1995 and 1999 Plans are administered
by the Compensation Committee of the Board of Directors.

   On August 24, 1999, the Company amended the 1995 Plan due to the change in
control that resulted from the Agreement (See Note 3). The 1995 Plan was
amended to extend the exercise date for all options issued prior to July 1,
1999 to one year from the following dates: (1) the termination date of
employees if the termination date is without cause and occurred during the six-
month period commencing with the closing of the Purchase Agreement; (2) the
date of termination for employees terminated for "Good Reason" as defined in
such employee's employment agreement; and (3) the date of resignation of a
holder who is also a director who resigns at closing of the Agreement.

   The extension of the exercise period of the employee stock options resulted
in a new measurement date and compensation expense, equal to the intrinsic
value of all of the outstanding options, of approximately $730,000, was
recognized as stock compensation.

   Information relating to stock options and certain warrants is summarized
below:

   Options to acquire 75,000 shares of the Company common stock at an exercise
price of $16.50 were granted outside of the 1995 Plan on February 13, 1997 to
certain officers of the Company. Warrants to acquire 25,000 shares of the
Company common stock at an exercise price of $15.00 were granted outside of the
1995 Plan on September 15, 1998 to a consultant (See Note 11). Both grants are
included in the table above. Warrants to purchase 1,216,822 shares and 266,226
shares of common stock at $3.00 per share were issued on August 27, 1999 and
October 19, 1999, respectively, and are excluded from the table above because
the warrants were issued in conjunction with the sales of stock and are not
stock-based compensation.

(11) STOCKHOLDERS' EQUITY

 Preferred Stock-Series A

   On September 4, 1996, the Company signed a stock purchase agreement with
Kaiser Francis Oil Company ("Kaiser-Francis"). Kaiser-Francis agreed to
purchase 1,666,667 shares of Series A Preferred Stock ("Series A") at $6.00 per
share, for a total investment of $10 million. The parties agreed to a five-year
purchase period, effective September 4, 1996, with minimum incremental
investments of $500,000 each. Each issuance of Series A was subject to approval
by Kaiser-Francis of the use of proceeds. The Series A was nonvoting and
accrued dividends at 8% per annum, payable quarterly in cash. The Series A was
convertible at any time after issuance into shares of common stock at the rate
of 0.66 shares of common stock for each share of Series A before January 1,
1998. The conversion rate decreases for every full year (excluding partial
years) thereafter at 8% per annum. As of December 31, 1997, 1,666,667 shares of
the Series A had been issued. On January 31, 1998 Kaiser-Francis converted 100%
of the Series A into 1,111,111 common shares of the Company.

 Preferred Stock--Series B

   In connection with the merger of Shore Oil Company , effective June 30,
1997, the Company issued 266,667 shares of Series B Preferred Stock ("Series
B"). The Series B is nonvoting and pays no dividends. The Series B has a
liquidation value of $7.50 per share. Until December 31, 2002, any holder of
the Series B may convert all or any portion of Series B shares into Company
Common Stock ("Common") at the greater ratio of (i) three shares of Series B
for one share of Common or (ii) at a ratio based upon the "Alternative
Conversion Factor." The Alternative Conversion Factor is determined by dividing
the net increase in value of approximately 40,000 net mineral acres owned by
the Company in South Louisiana by $8,000,000 and multiplying the product by
355,333 to arrive at the potential number of total Common shares all holders
would receive upon conversion. In no event shall the aggregate total number of
shares of Common into which the Series B are converted be less than 88,889
shares or exceed 444,444 shares, unless further increased for any anti-dilution
provisions. Upon expiration of the conversion period, unless the Company has
given notice to redeem the Series B, all of the shares of the Series B shall be
automatically converted.

   At December 31, 1999, the value of the fee minerals had increased to a level
that resulted in the Series B shares being convertible into an additional 1,891
common shares applying the Alternative Conversion Factor. At December 31, 1999,
none of the Series B had been converted.

 Preferred Stock--Series C

   In connection with the Enex Partnership Acquisition, on December 30, 1998,
the Company issued 2,177,481 shares of Series C Preferred Stock ("Series C") in
exchange for 100% of the Enex Partnership units. The holders of Series C are
entitled to receive cumulative cash dividends in an amount per share of $0.50
per year (10% annual rate), payable semi-annually on March 31 and September 30
of each year. These dividends are payable in preference to and prior to the
payment of any dividend or distribution to any holder of Company common stock
or other junior security. The Series C dividends began to accrue on December
30, 1998. The banks have granted the Company a waiver allowing the Company to
pay the dividends on the Series C as long as no default or event of default
exists or would exist as a result of any Series C dividend payment. The Series
C has a liquidation preference of $5.00 per share plus an amount equal to all
accumulated, accrued and unpaid dividends. The liquidation preference of Series
C ranks on parity with the Series B.

   Each share of Series C is convertible into one-third share of Company common
stock. On or after January 1, 2000, the Company may redeem all or a portion of
the Series C, at its option, at a purchase price of $5.00 per share, plus an
amount equal to all accumulated, accrued and unpaid dividends.

   The Series C is generally nonvoting; however, holders of Series C are
entitled to vote on any amendment, alteration or appeal of any provision of the
Company's Articles of Incorporation which would adversely affect any holder's
rights and preferences.

   As a result of its limited partnership interest in the Enex Partnership,
Enex owns 1,293,522 shares of the Series C of which the Company owns 80%, or
1,034,818 shares through its 80% ownership of Enex.

 Common Stock and Warrants

   On August 27, 1999, the Company sold W/E LLC 1,585,185 shares of common
stock and five-year warrants to purchase 1,200,000 shares of common stock for
$9.8 million in cash and oil and natural gas properties valued at $875,000. On
the same date, the Company sold 22,222 shares of common stock and five-year
warrants to purchase 16,822 shares of common stock to Shoemaker for $150,000
(See Notes 3 and 7). On

October 19, 1999, the Company closed a private placement of securities to
Prudential. The economic terms and conditions of the private placement are
similar to those of the securities purchase agreement with W/E LLC and
Shoemaker entered into on July 1, 1999. The private placement consisted of the
sale of 351,681 shares of common stock and five-year warrants to purchase
266,226 shares at $3.00 per share of common stock for $2.4 million and a five-
year senior subordinated convertible note for $2.4 million (See Note 7).

   The warrants issued to W/E LLC, Shoemaker and Prudential are exercisable for
$3.00 per share and expire five years from the issue date. Sixty percent of the
warrants are immediately exercisable, in whole or in part at any time until the
expiration date. An additional 10% of the warrants may be exercised at each
anniversary of the grant date until expiration. On the occurrence of either a
change of control, payment in full of the Senior Notes or conversion of the
entire principal balance of the Senior Notes, all of the warrants become
immediately exercisable. If less than the entire principal balance of the
Senior Notes are converted, a pro-rata portion of the warrants will be
convertible based on the portion of the Senior Notes that are converted.

   On September 15, 1998 the Company entered into a consulting agreement with
Edward K. Andrew ("Andrew") for a term of five years beginning January 1, 1999.
As compensation, the Company granted to Andrew a warrant to purchase 25,000
shares of Company common stock at a price of $15.00. The warrants vested over
the period September 15, 1998 to January 1, 1999. The estimated fair value of
the warrants was determined at the date of grant and charged to stock
compensation expense over the vesting period.

   On February 13, 1997, the Company awarded to certain officers 16,364 shares
of restricted stock of the Company. The restricted stock awards were contingent
on the performance of services to the Company in the future with 50% of the
restricted shares being earned over the six month period July 1, 1997 to
December 31, 1997 and 50% over the six month period January 1, 1998 to June 30,
1998. All restricted shares were earned and issued as of December 31, 1998.

 Earnings Per Share

   At December 31, 1999 and 1998, the Company had a weighted average of
1,149,476 and 283,297, combined stock options, warrants and convertible
preferred stock and notes outstanding, respectively, which were not included in
the computation of diluted earnings per share, because the effect of the
assumed exercise of these stock options, warrants and convertible securities
would have an antidilutive effect on the computation of diluted loss per share.
At December 31, 1999 and 1998, the Company had outstanding convertible
preferred stock that was convertible into 469,744 and 469,778 shares of common
stock, and dividends of $574,080 and $67,945, respectively, which were not
reflected in the computation of diluted earnings per share, because the effect
of the assumed conversion of these preferred shares would have an antidilutive
effect on the computation of diluted loss per share. At December 31, 1999, the
Company had $4,154,292 weighted average face value of convertible subordinated
notes that were convertible into 461,588 shares of common stock and interest
expense of $376,367, which were not reflected in the computation of diluted
earnings per share, because the effect of the assumed conversion of these
subordinated notes would have an antidilutive effect on the computation of
diluted loss per share.

(12) COMMITMENTS AND CONTINGENCIES

   The Company is obligated under the terms of certain operating leases for
office space that continue through January 31, 2005. Total rent expense was
$267,337 and $268,477 for the years ended December 31, 1999 and 1998,
respectively. Future minimum rental payments under the Company's leases total
$309,372, $248,694, $194,016, $194,016 and $194,016 for the years ending
December 31, 2000 through 2004, respectively.

   On November 18, 1999, the Company's shareholders approved a reincorporation
of the Company from Alabama to Delaware (See Note 1). The Alabama Code has a
shareholder dissent provision that allows a shareholder to dissent from the
reincorporation and demand cash payment equal to the fair value of the common
stock owned at the date of the reincorporation. Before the November 18
meeting, the Company received shareholder dissents representing ownership of
99,438 shares of common stock. Over the period December 15, 1999 to January
25, 2000, the Company received formal demands for payment from the dissenting
shareholders (the "dissenters"). The Company expects to make an offer to the
dissenters before March 10, 2000. Once the offer is made, the dissenters have
30 days to accept the offer or make a counteroffer. If the Company and the
dissenters cannot reach agreement on the fair value of the common shares
within 60 days of the dissenters' counteroffer, if any, the matter is then
moved to the Circuit Court of Washington County, Alabama for resolution. The
exact amount to be paid to the dissenters for their common shares cannot be
determined at this time. Based on the Company's closing stock price on
November 23, 1999 of $11.25 per share and accrued interest from November 23,
1999, the Company accrued the estimated cash payment to the dissenters of
approximately $1.1 million.

   As of December 31, 1999, the Company had $55,000 of irrevocable standby
letters of credit outstanding.

   The Company is a defendant in various legal proceedings which are
considered routine litigation incidental to the Company's business, the
disposition of which management believes will not have a material effect on
the financial position or results of operations of the Company.

(13) FINANCIAL INSTRUMENTS

   In April 1999, the Company entered into costless collar hedges for
approximately 3,650 Mcf per day with a weighted average floor and ceiling of
$2.06 and $2.20, respectively, for the months of May through October of 1999.
During the year ending December 31, 1999, the Company incurred hedging losses
of approximately $164,000. At December 31, 1999, the Company had no open
derivative instruments.

   Fair value of cash, receivables and payables approximates carrying value.
Fair value of long-term debt also approximates carrying value due to the
nature of the Facility, whereby the interest rates are floating rates which
reflect market rates.

   At December 31, 1999, the fair value of the $13.2 million senior
subordinated convertible notes was $13.1 million.

(14) SUBSEQUENT EVENTS

   On January 14, 2000, the Company's stockholders voted to effect a one-for-
three reverse split of the Company's common stock for the stockholders of
record on December 9, 1999. The reverse stock split resulted in a decrease of
10,677,542 in the number of shares issued at December 31, 1999, 14,515 of
which are held in treasury. The par value of these shares was transferred to
additional paid-in capital. All common share and earnings per common share
amounts as of December 31, 1999 and 1998 have been retroactively restated in
the accompanying consolidated financial statements to reflect the reverse
stock split.

   On February 3, 2000, the Company closed the acquisition of Magellan
Exploration, LLC ("Magellan"), a privately held Delaware limited liability
company, for an estimated purchase price of $18.3 million. In connection with
the acquisition, the Company issued 1,085,934 common shares and warrants to
purchase 333,333 shares of common stock with an exercise price of $30.00 per
share, which are exercisable for four years. The Company also issued 617,008
shares of Series D convertible preferred stock with a stated value of

for the Company to pay the dividends in additional Series D shares and with
each Series D share convertible at any time into Company common stock on a one-
for-one basis. The Company may redeem the Series D shares upon 30 days written
notice and there are no rights of holders to "put" the Series D shares to the
Company. The owners of Magellan also received a 5% "Back-In" working interest
in twelve (12) exploration prospects.

 Estimated Quantities of Reserves

   The Company has interests in oil and natural gas properties that are located
principally in Texas, Louisiana, Kansas, Oklahoma and New Mexico. The Company
does not own or lease any oil and natural gas properties outside the United
States. There are no quantities of oil and natural gas subject to long-term
supply or similar agreements with any governmental agencies.

   The Company retains independent engineering firms to provide year-end
estimates of the Company's future net recoverable oil, natural gas and natural
gas liquids reserves. In 1999, such estimates were prepared by Ryder Scott
Company. In 1998, such estimates were prepared by Lee Keeling and Associates,
Inc. and H.J. Gruy & Associates, Inc.. The reserve information was prepared in
accordance with guidelines established by the Securities and Exchange
Commission.

   Estimated proved net recoverable reserves as shown below include only those
quantities that can be expected to be commercially recoverable at prices and
costs in effect at the balance sheet dates under existing regulatory practices
and with conventional equipment and operating methods. Proved developed
reserves represent only those reserves expected to be recovered through
existing wells. Proved undeveloped reserves

 Standardized Measure of Discounted Future Net Cash Flows From Proved Reserves

   The following is a summary of the standardized measure of discounted future
net cash flows related to the Company's proved oil and natural gas reserves.
For these calculations, estimated future cash flows from estimated future
production of proved reserves are computed using oil and natural gas prices as
of the end of each period presented. Future development and production costs
attributable to the proved reserves were estimated assuming that existing
conditions would continue over the economic lives of the individual leases and
costs were not escalated for the future. Estimated future income taxes were
calculated by applying statutory tax rates (based on current law adjusted for
permanent differences and tax credits) to the estimated future pre-tax net
cash flows related to proved oil and natural gas reserves, less the tax basis
of the properties involved.

   The Company cautions against using this data to determine the value of its
oil and natural gas properties. To obtain the best estimate of the fair value
of the oil and natural gas properties, forecasts of future economic conditions,
varying discount rates, and consideration of other than proved reserves would
have to be incorporated into the calculation. In addition, there are
significant uncertainties inherent in estimating quantities of proved reserves
and in projecting rates of production that impair the usefulness of the data.

proved oil and natural gas reserves for the years ended December 31, 1999 and
1998 are summarized as follows (in thousands):

   During recent years, there have been significant fluctuations in the prices
paid for oil in the world markets. The situation has had a destabilizing effect
on posted prices for oil in the United States, including the posted prices paid
by purchasers of the Company's oil. The period end prices of oil and natural
gas at December 31, 1999 and 1998, used in the above table were $23.64 and
$9.50 per barrel of oil and $2.23 and $2.10 per thousand cubic feet of natural
gas, respectively.

standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the statements. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

   The accompanying statements were prepared as described in Note 2 for the
purpose of complying with certain rules and regulations of the Securities and
Exchange Commission ("SEC") for inclusion in certain SEC regulatory reports and
filings and are not intended to be a complete financial presentation.

   In our opinion, the statements referred to above present fairly, in all
material respects, the revenues and direct operating expenses of the Floyd Oil
Properties for the nine months ended September 30, 1999, and for the year ended

                            THE FLOYD OIL PROPERTIES

         NOTES TO STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES

1. The Properties

   On November 23, 1999, 3TEC Energy Corporation ("3TEC Energy"), formerly
known as Middle Bay Oil Company, Inc., acquired certain oil and gas properties
and interests (the "Floyd Oil Properties") from Floyd Oil Company ("Floyd") and
certain partnerships and other entities managed or sponsored by Floyd
(collectively, the "Sellers") for a purchase price of approximately $87 million
in cash and 1.5 million shares (prior to the planned 1 for 3 reverse stock
split) of 3TEC Energy's common stock. The effective date of the transaction was
January 1, 1999. The majority of the Floyd Oil Properties are located in Texas
and Louisiana.

2. Basis of Presentation

   During the periods presented, the Floyd Oil Properties were not accounted
for or operated as a separate division by Floyd. Information with respect to
depreciation, depletion and amortization is not available for the Floyd Oil
Properties. General and administrative expenses incurred by Floyd were not
allocated to the Floyd Oil Properties. The Sellers were not taxpaying entities,
and therefore income tax information with respect to the Floyd Oil Properties
is not available. Accordingly, full separate financial statements prepared in
accordance with generally accepted accounting principles do not exist and are
not practicable to obtain in these circumstances.

   Revenues and direct operating expenses included in the accompanying
statements represent the Sellers' net working and royalty interests in the
Floyd Oil Properties and are presented on the accrual basis of accounting.
Depreciation, depletion and amortization, allocated general and administrative
expenses and income tax expense have been excluded.

   The statements presented are not indicative of the future results of
operations of the Floyd Oil Properties due to anticipated changes in various
operating expenses and the omission of other costs as discussed above.

3. Commitments and Contingencies

   The management of 3TEC Energy is not aware of any legal, environmental or
other commitments or contingencies that would be materially important in
relation to the revenues and direct operating expenses of the Floyd Oil
Properties.

4. Related Party Transactions

   An affiliate of Floyd operated certain oil and gas wells included in the
Floyd Oil Properties. Fees related to such wells in the amount of $460,000 were
charged to the Floyd Oil Properties during the year ended December 31, 1998,
and $353,700 for the nine month period ended September 30, 1999. These fees are
reflected in direct operating expenses in the accompanying statements.

5. Capital Expenditures (Unaudited)

   Direct operating expenses do not include exploration and development
expenditures related to the Floyd Oil Properties which totaled $4.1 million for
the year ended December 31, 1998, and $2.6 million for the nine month period
ended September 30, 1999.

6. Supplemental Oil and Gas Reserve Information (Unaudited)

   Total proved and proved developed oil and gas reserves of the Floyd Oil
Properties at December 31, 1998 have been estimated based on reserve estimates
prepared by Ryder Scott Company Petroleum Engineers as of September 30, 1999,
adjusted for production from December 31, 1998 to September 30, 1999.

estimates were not readily available for subsequent or prior periods.
Therefore, reserves for December 31, 1998 have been calculated by adjusting the
September 30, 1999 amounts for the 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 September 30, 1999. The
future net cash flows from production of these proved reserve quantities were
computed by applying current prices of oil and gas, averaging $22.44 per barrel
of oil and $2.75 per thousand cubic foot of gas (with consideration of price
changes only to the extent provided by contractual arrangements) as of
September 30, 1999 to estimated future production of proved oil and gas
reserves less the estimated future expenditures (based on current costs) as of
September 30, 1999, to be incurred in developing and producing the proved
reserves. As discussed above, income tax information for the Floyd Oil
Properties is not available and therefore is not presented.

The Board of Directors
C. W. Resources, Inc.:

   We have audited the accompanying statement of revenues and direct operating

well as evaluating the overall statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

   The accompanying statement was prepared as described in note 2 for the
purpose of complying with certain rules and regulations of the Securities and
Exchange Commission (SEC) for inclusion in certain SEC regulatory reports and
filings and is not intended to be a complete financial presentation.

   In our opinion, the statement referred to above presents fairly, in all
material respects, the revenues and direct operating expenses of CWR Properties
for the year ended December 31, 1999, in conformity with generally accepted
accounting principles.

          NOTES TO STATEMENT OF REVENUES AND DIRECT OPERATING EXPENSES

                               December 31, 1999

(1) Basis of Presentation

   The accompanying financial statement presents the revenues and direct
operating expenses of oil and gas properties (the CWR Properties) to be
acquired by 3TEC Energy Corporation from C. W. Resources, Inc. and its related
parties, Westerman Royalty, Inc. and Carl A. Westerman. The CWR Properties are
located in East Texas.

   The accompanying financial statement was derived from the historical
accounting records of C. W. Resources, Inc. Direct operating expenses include
lease and well repairs, maintenance and other direct operating expenses.
Memorandum adjustments have been made to the financial information in order to
present the accompanying financial statement in accordance with generally
accepted accounting principles.

   C. W. Resources, Inc. has made a number of estimates and assumptions
relating to the preparation of the financial statement in conformity with
generally accepted accounting principles. Actual results could differ from
those estimates.

(2) Omitted Historical Financial Information

   Full historical financial statements, including general and administrative
expense, income tax expense and interest expense have not been presented
historically because the CWR Properties were not accounted for or operated as a
separate division by C. W. Resources, Inc. or its related parties. Historical
depletion expense, including abandonment provision, also has not been included
as the basis in the properties will be adjusted in the purchase price
allocation when the properties are acquired by 3TEC Energy Corporation;
therefore, historical depletion no longer will be relevant.

(3) Commitments and Contingencies

   The management of C. W. Resources, Inc. is not aware of any legal,
environmental or other commitments or contingencies that would be materially
important in relation to the revenues and direct operating expenses of the CWR
Properties.

   Substantially all gas production from the CWR Properties is marketed by one
third party. Substantially all oil production is marketed by another third
party.

(4) Related Party Transactions

   C. W. Resources, Inc. operated the oil and gas wells included in the CWR
Properties. Fees related to such wells in the amount of approximately $360,000
were charged to the CWR Properties during the year ended December 31, 1999. The
fee is reflected in lease operating expenses in the accompanying statement.

(5) Capital Expenditures

   Direct operating expenses do not include exploration and development
expenditures related to the CWR Properties which totaled approximately $3.1
million for the year ended December 31, 1999.

(6) Supplemental Oil and Gas Reserve Information (Unaudited)

   Total proved and proved developed oil and gas reserves of the CWR Properties
at December 31, 1999 have been estimated based on reserve estimates prepared by
Ryder Scott Company, independent petroleum engineers as of January 1, 2000. No
comparable estimates were available for prior periods. Therefore, reserves

                                      F-31
<PAGE>

                                 CWR PROPERTIES

   NOTES TO STATEMENT OF REVENUES AND DIRECT OPERATING EXPENSES--(Continued)

for December 31, 1998 have been calculated by adjusting the December 31, 1999
amounts for the year's activities and, consequently, no revisions of previous
estimates have been reflected. All reserve estimates are based on economic and
operating conditions existing at January 1, 2000. The future net cash flows
from production of these proved reserve quantities were computed by applying
current prices of oil and gas, averaging $25.60 per barrel of oil and $2.39 per
thousand cubic foot of gas (with consideration of price changes only to the
extent provided by contractual arrangements) as of January 1, 2000 to estimated
future production of proved oil and gas reserves less the estimated future
expenditures (based on current costs) as of January 1, 2000 to be incurred in
developing and producing the proved reserves. As discussed above, income tax
information for the Company is not available and therefore is not presented.

Unaudited Pro Forma Supplemental Oil and Gas Disclosure

   The following tables set forth certain unaudited pro forma information
concerning 3TEC's proved oil and gas reserves at September 30, 1999, giving
effect to the acquisition of the Floyd Oil Properties as if they had occurred
on January 1, 1998. There are numerous uncertainties inherent in estimating the
quantities of proved reserves and projecting future rates of production and
timing of development expenditures. The following reserve data represent
estimates only and should not be construed as being exact. The proved oil and
gas reserve information is as of September 30, 1999 and reflects prices and
costs in effect as of such date.

Item 15. Indemnification of Officers And Directors

   Delaware law authorizes corporations to limit or eliminate the personal
liability of their officers and directors to them and their stockholders for
monetary damages for breach of officers' and directors' fiduciary duty of care.
The duty of care requires that, when acting on behalf of the corporation,
officers and directors must exercise an informed business judgment based on all
material information reasonably available to them. Absent the limitations
authorized by Delaware law, officers and 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.

   Our certificate of incorporation limits the liability of our directors to us
or our stockholders to the fullest extent permitted by Delaware law.
Specifically, our directors will not be personally liable for monetary damages
for breach of a director's fiduciary duty in their capacity as directors,
except for liability:

  -  for any breach of the director's duty of loyalty to us or our
     stockholders;

  -  for acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law;

  -  for unlawful payments of dividends or unlawful stock repurchases or
     redemptions as provided in Section 174 of the Delaware General
     Corporation Law; or

  -  for any transaction from which the director derived an improper personal
     benefit.

   Delaware law also authorizes corporations to indemnify its officers,
directors, employees and agents for liabilities, other than liabilities to the
corporation, arising because that individual was an officer, director, employee
or agent of the corporation so long as the individual acted in good faith and
in a manner he or she reasonably believed to be in the best interests of the
corporation and not unlawful.

   Our bylaws provide that our officers and directors will be indemnified by us
for liabilities arising because that individual was one of our officers or
directors to the fullest extent permitted by Delaware law. Our bylaws also
provide that we may, by action of our board of directors, provide similar
indemnification to our employees and agents.

                                      II-1
<PAGE>

   These provisions in our certificate of incorporation and our bylaws may
reduce the likelihood of derivative litigation against our officers and
directors and may discourage or deter our stockholders or management from
bringing a lawsuit against our officers and directors for breach of their duty
of care, even though the action, if successful, might otherwise have benefitted
us and our stockholders.

   These provisions in our certificate of incorporation and bylaws do not alter
the liability of our officers and directors under federal securities laws and
do not affect the right to sue under federal securities laws for violations
thereof.

Item 17. Undertakings

   We hereby undertake to:

     (1) To file, during any period in which offers or sales are being made
  of the securities registered hereby, a post-effective amendment to this
  registration statement:

       (i) To include any prospectus required by section 10(a)(3) of the
    Securities Act of 1933, as amended;

       (ii) To reflect in the prospectus any facts or events arising after
    the effective date of this registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in this registration statement; and

       (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in this registration statement
    or any material change to such information in this registration
    statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii)
above do not apply if the information required to be included in a post-
effective amendment by those paragraphs is contained in periodic reports filed
by the registrant pursuant to section 13 or section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in this Registration
Statement.

     (2) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment 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.

     (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

     (4) That, for purposes of determining any liability under the Securities
  Act, each filing of our annual report pursuant to section 13(a) or section
  15(d) of the Exchange Act (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to section 15(d) of the
  Exchange Act) that is incorporated by reference in this registration
  statement shall be deemed to be a new registration statement relating to
  the securities offered herein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

     (5) Insofar as indemnification for liabilities arising under the
  Securities Act of 1933 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
  SEC such indemnification is against public policy as expressed in the
  Securities Act of 1933 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 the securities being registered, the
  registrant will, unless in the opinion of its counsel the matter has been
  settled by controlling precedent, submit to a court of appropriate
  jurisdiction the question whether such indemnification by it is against
  public policy as expressed in the Securities Act of 1933 and will be
  governed by the final adjudication of such issue.

                              EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as of

     employees under its normal payroll practices.

          (b) In addition, Employee shall be eligible to receive an annual bonus

     6.  Business Opportunities and Intellectual Property.

     (a) During the period in which Employee is employed by the Company,
Employee shall promptly disclose to the Company all "Business Opportunities" and
"Intellectual Property" (each as defined below).

     (b) Employee hereby assigns and agrees to assign to the Company, its
successors, assigns or designees, all of Employee's right, title and interest in
and to all "Business Opportunities" and "Intellectual Property," and further
acknowledges and agrees that all Business Opportunities and Intellectual
Property constitute the exclusive property of the Company.

     (c) For purposes hereof, "Business Opportunities" shall mean all business
ideas, prospects, proposals or other opportunities pertaining to the lease,
acquisition, exploration, production, gathering or marketing of hydrocarbons and
related products and the exploration potential of geographical areas on which
hydrocarbon exploration prospects are located, which are:

          (i) developed by Employee (A) during the period in which Employee is
     employed by the Company, or (B) before the period in which Employee is
     employed by the Company, but only to the extent of Employee's rights
     thereto during such period, or

          (ii) originated by any third party and brought to the attention of
     Employee (A) during the period in which Employee is employed by the
     Company, or (B) before the period in which Employee is employed by the
     Company, but only to the extent of Employee's rights thereto during such
     period,

together with information relating thereto, including, without limitation, any
"Business Records" (as defined below).

     (d) For purposes hereof "Intellectual Property" shall mean all ideas,
inventions, discoveries, processes, designs, methods, substances, articles,
computer programs and improvements (including, without limitation, enhancements
to, or further interpretation or processing of, information that was in the
possession of Employee prior to the date of this Agreement), whether or not
patentable or copyrightable, which do not fall within the definition of Business
Opportunities, which are discovered, conceived, invented, created or developed
by Employee, alone or with others: (i) during the period in which Employee is
employed by the Company if such discovery, conception, invention, creation, or
development (A) occurs in the course of the Employee's employment with the
Company, or (B) occurs with the use of any of the Company's time, materials or
facilities, or (C) in the opinion of the Board of Directors of the Company,
relates or pertains in any way to the Company's purposes, activities or affairs,

     7.  Non-Competition and Non-Disclosure; Injunctive Relief.   Employee
acknowledges that the services he is to render in the course of his employment
by the Company are of a special and unusual character with unique value to the
Company.  In view of the value to the Company of the services of Employee during
the course of his employment by the Company, because of the Business
Opportunities, Intellectual Property and "Confidential Information" (as defined
below) to be obtained by or disclosed to Employee, and as a inducement to the
Company to enter into this Agreement and to pay to Employee the compensation
stated herein, Employee covenants and agrees as follows:

     (a) During the period in which Employee is employed by the Company,
Employee shall not directly or indirectly be employed by or render advisory,
consulting or other services in connection with any business enterprise or
person that is engaged in leasing, acquiring, exploring, producing, gathering or
marketing hydrocarbons and related products.

     (b) During the period in which Employee is employed by the Company,
Employee shall not, directly or indirectly, in any capacity (including, without
limitation, as a proprietor, investor, director or officer or in any other
individual or representative capacity), be financially interested in or engage
in any business that is engaged in leasing, acquiring, exploring, producing,
gathering or marketing hydrocarbons and related products (the "E & P Business");
however, it is specifically agreed between the parties that Employee may
continue to be financially interested in and engage in any E & P Business that
is described on Exhibit A attached hereto, provided, that such activities do not
materially detract from the Employee's performance of his responsibilities as
Chief Executive Officer, provided, further that, nothing contained in this
paragraph 7(b) shall relieve the Employee of his obligations contained in
paragraph 7(a) above.   In addition, Employee may make investments in publicly
traded companies that engage in the E & P Business, provided such investments
represent less than one percent (1%) of the issued and outstanding shares of
such company.

     (c) During the period in which Employee is employed by the Company, all
investments made by Employee (whether in his own name or in the name of any
family members), which relate to the lease, acquisition, exploration,
production, gathering or marketing or hydrocarbons and related products shall be
made solely through the Company; and Employee will not (directly or indirectly
through any family members), (i) invest or otherwise participate alongside the
Company in any Business Opportunities, or (ii) invest or otherwise participate
in any business or activity relating to a Business Opportunity, regardless of
whether the Company ultimately participates in such business or activity.

     (d) During the period in which Employee is employed by the Company and
thereafter, Employee will not disclose to any third party or directly or
indirectly make use of, in a way materially detrimental to the Company, any and
all trade secrets and confidential or proprietary information pertaining to the
Company (collectively referred to as "Confidential

                                       4
<PAGE>

Information"). For purposes of this Section 7, it is agreed that Confidential
Information includes, without limitation, any information heretofore or
hereafter acquired, developed or used by the Company relating to Business
Opportunities or Intellectual Property or other geological, geophysical,
economic, financial or management aspects of the business, operations,
properties or prospects of the Company whether oral or in written form in a
"Business Records" (as defined in paragraph 7(g) below). Notwithstanding the
foregoing, no information of the Company will be deemed confidential for the
purposes of this paragraph 7(d) if such information is or becomes public
knowledge through no act of Employee or was previously known by Employee prior
to entering into this Agreement.

     (e) During the Employment Period or the period in which Employee is
employed by the Company, whichever is longer, and for a six-month period
commencing upon the termination of such longer period, Employee may not solicit,
raid, entice or induce, directly or indirectly, any employee (or person who
within the preceding ninety (90) days was an employee) of the Company or any
other person who is under contract with or rendering services to the Company, to
(i) terminate his employment by, or contractual relationship with, the Company,
(ii) refrain from extending or renewing the same (upon the same or new terms),
(iii) refrain from rendering services to or for the Company, or (iv) become
employed by or to enter into contractual relations with any persons other than
the Company.

     (f) Employee acknowledges and agrees that the services to be rendered by
him are of a special, unique and extraordinary character and, in connection with
such services, he will have access to Business Opportunities, Intellectual
Property and Confidential Information vital to the Company's businesses.  By
reason of this, the Employee consents and agrees that if he violates any of the
provisions of this Section 7, the Company would sustain irreparable harm and,
therefore, in addition to any other remedies which the Company may have under
this Agreement or otherwise, the Company shall be entitled to an injunction
restraining the Employee from committing or continuing any such violation of
this Agreement.  Such right to an injunction shall be cumulative and in addition
to, and not in lieu of, any other remedies to which the Company may show itself
justly entitled.  Further, during any period in which the Employee is in breach
of the covenants set forth in this Section 7, the time period of this covenant
shall be extended for an amount of time that the Employee is in breach.

     (g) The Employee agrees to promptly deliver to the Company, upon
termination of Employee's employment with the Company, or at any other time when
the Company so requests, all documents relating to the business of the Company,
including, without limitation: all geological and geophysical reports and
related data such as maps, charts, logs, seismographs, seismic records and other
reports and related data, calculations, summaries, memoranda and opinions
relating to the foregoing, production records, electric logs, core data,
pressure data, lease files, well files and records, land files, abstracts, title
opinions, title or curative matters, contract files, notes, records, drawings,
manuals, correspondence, financial and accounting information, customer lists,
statistical data and compilations, patents, copyrights,

                                       5
<PAGE>

trademarks, trade names, inventions, formulae, methods, processes, agreements,
contracts, manuals or any other documents relating to the business of the
Company (collectively, the "Business Records"), and all copies thereof and
therefrom. The Employee confirms that all of the Business Records (and all
copies thereof and therefrom) that are required to be delivered to the Company
pursuant to this paragraph 7(g) constitute the exclusive property of the
Company. The obligation of confidentiality set forth in this Section 7 shall
continue notwithstanding the Employee's delivery of any such documents to the
Company. Notwithstanding the foregoing provisions of this Section 7 or any other
provision of this Agreement, the Employee shall be entitled to retain any
written materials which, as shown by the Employee's records, were in Employee's
possession on or prior to the date hereof, subject to the Company's right to
receive a copy of all such materials.

     (h) The representations and covenants contained in this Section 7 on the
part of the Employee will be construed as ancillary to and independent of any
other provision of this Agreement, and the existence of any claim or cause of
action of the Employee against the Company or any officer, director, or
shareholder of the Company, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by the Company of the
covenants of the Employee contained in this Section 7.  In addition, the
provisions of this Section 7 shall continue to be binding upon the Employee in
accordance with their terms, notwithstanding the termination of the Employee's
employment hereunder for any reason.

     (i) The parties to this Agreement agree that the limitations contained in
this Section 7 with respect to time, geographical area, and scope of activity
are reasonable.  However, if any court shall determine that the time,
geographical area, or scope of activity of any restriction contained in this
Section 7 is unenforceable, it is the intention of the parties that such
restrictive covenants set forth herein shall not thereby be terminated but shall
be deemed amended to the extent required to render it valid and enforceable.

     8.  Termination of Employment

     (a) Death.  Employee's employment shall terminate automatically upon
Employee's death.

     (b) Termination of Employment By the Company For Cause.  The Company may
terminate Employee's employment under this Agreement for Cause.  For purposes
hereof, the term "Cause" shall mean (i) the inability of Employee, despite any
reasonable accommodation required by law, due to bodily injury or disease or any
other physical or mental incapacity, to perform the services provided for
hereunder for a period of 120 days in the aggregate, within any given period of
180 consecutive days during the term of this Agreement, in addition to any
statutorily required leave of absence, (ii) conduct of the Employee that
constitutes fraud, theft, or a criminal act involving moral turpitude, in each
case only if it materially affects his ability to perform the duties and
responsibilities of his position or has a material adverse effect on the

                                       6
<PAGE>

Company, (iii) commission of a material act of fraud against the Company, (iv)
embezzlement of funds or misappropriation of other property by the Employee from
the Company; (v) failure of Employee to observe or perform his material duties
and obligations as an employee of the Company or a material breach of this
Agreement, after thirty (30) days advance written notice of such failure or
breach which has not been cured; (vi) Employee's habitual use of illegal
controlled substances, or intoxication during normal business hours while
conducting the Company's business, which, in the reasonable judgment of the
Board, so impairs  Employee's credibility and reputation that Employee can no
longer perform his duties; or (vii) Employee has been found civilly liable for
sexual harassment or related offenses (or the Company has been found civilly
liable for such actions by Employee).

     (c) Termination By the Company Without Cause.  The Company may also
terminate Employee's employment under this Agreement without Cause.

     (d) Termination By Employee for Good Reason.  If a Change of Control (as
defined hereafter) in the Company has occurred, Employee may terminate his
employment during the Employment Period for Good Reason (defined hereafter) upon
thirty (30) days' notice to the Company.  For purposes of this Agreement, the
term "Good Reason" shall mean the occurrence, without Employee's express written
consent, of any one or more of the following events:

          (i) A material change in Employee's duties (without the consent of
     Employee) or a change in the title or offices held by Employee, or any
     occurrence which causes Employee to have his principal place of employment
     somewhere other than Houston, Texas.

          (ii) A reduction in Employee's compensation or the failure by the
     Company to continue to provide prompt payment (or reimbursement to
     Employee) of all reasonable expenses incurred by Employee in connection
     with Employee's professional and business activities.

          (iii)  A failure by the Company to waive any and all restrictions that
     might exist on the exercise of any stock options held by Employee under the
     Company's stock option plans as of the date of a Change of Control.

          (iv) The failure of the Company to obtain the assumption of this
     Agreement, without limitation or reduction, by any successor to the
     Company.

     (e) Change of Control.  A "Change of Control" shall have occurred if:

          (i) fifty percent (50%) or more of the outstanding common stock of the
     Company has been acquired by any person or persons (as defined in Section
     3(a)(9) of the Securities Exchange Act of 1934 (the "Act")), provided such
     person(s) is not a

                                       7
<PAGE>

     stockholder(s) of the Company currently holding ten percent (10%) or more
     of the outstanding common stock of the Company at the time of the execution
     of this Agreement. For purposes of this paragraph 8, such person shall
     include affiliated persons (as defined in the Act));

          (ii) there has been a merger or equivalent combination involving the
     Company after which fifty percent (50%) or more of the voting stock of the
     surviving corporation is held by persons other than those persons who were
     stockholders holding ten percent (10%) or more of the outstanding stock of
     the Company immediately prior to the date of such merger or equivalent
     combination; or

          (iii)  there has been a merger or equivalent combination or stock sale
     involving the Company and after such transaction fifty percent (50%) or
     more of the members of the surviving company's Board of Directors elected
     by stockholders are persons who were not directors immediately prior to
     such transaction; or

     (f) Voluntary Termination By Employee.  Employee shall have the right at
any time after the date hereof to voluntarily terminate his employment with the
Company (a "Voluntary Termination") for any reason in the sole discretion of
Employee by not less than thirty (30) days' prior written notice to the Company;
provided however, a termination without Cause or a termination for Good Reason
shall not be treated for any purpose hereunder as a Voluntary Termination.

     9.  Termination Procedures and Certain Definitions.

     (a) Notice of Termination.  Any termination by the Company for Cause,
without Cause or by Employee for Good Reason or in a Voluntary Termination,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with paragraph 13 of this Agreement.  For purposes of this
Agreement, a "Notice of Termination" means a written notice which (i) indicates
the specific termination provision in this Agreement relied upon, (ii) to the
extent applicable, sets forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of Employee's employment under the
provision so indicated and (iii) if the Date of Termination (as defined below)
is other than the date of receipt of such notice, specifies the termination
date.  The failure by Employee or the Company to set forth in the Notice of
Termination any fact or circumstance which contributes to a showing of Good
Reason or Cause shall not waive any right of Employee or the Company,
respectively, hereunder or preclude Employee or the Company, respectively, from
asserting such fact or circumstance in enforcing Employee's or the Company's
rights hereunder.  Employee's continued employment with the Company, after a
Notice of Termination is provided, shall not constitute consent to, or a waiver
of any rights with respect to, any circumstance constituting Good Reason
hereunder.

                                       8
<PAGE>

     (b) Date of Termination.  "Date of Termination" means (i) if Employee's
employment is terminated by the Company for Cause, the date of Employee's
receipt of the Notice of Termination or any later date specified therein, as the
case may be, (ii) if Employee's employment is terminated by the Company other
than for Cause, the Date of Termination shall be the date not less than thirty
(30) days after the date on which the Company notifies Employee of such
termination, and (iii) if Employee terminates his employment for Good Reason or
in a Voluntary Termination, the Date of Termination shall be the date, not less
than thirty (30) days after the date on which Employee notifies the Company of
such termination.

     10.  Obligations of the Company on Termination.

     (a) If during the Employment Period, Employee's employment is terminated
with Cause, upon Employee's death or upon a Voluntary Termination, the Company
shall immediately pay Employee in cash the portion of his Base Compensation
previously earned but not yet paid.

     (b) If during the Employment Period, Employee's employment is terminated by
the Company without Cause or by Employee for Good Reason:

               (i) In General.  The Company shall immediately pay Employee in
          cash the amount of his Total Compensation previously earned but not
          yet paid.

               (ii)  Severance Benefits.

                    (a) All stock options granted to Employee under the
               Company's stock option plans, which have not already vested,
               shall immediately vest and be exercisable.

                    (b) Employee shall continue to participate in all of the
               Company's welfare benefit plans, including health and medical
               plans, for six (6) months after termination and shall be entitled
               to reimbursement of COBRA payments to maintain medical and dental
               insurance up to twelve (12) additional months for said coverage.

                    (c) The Company shall pay Employee in a lump sum a
               "Severance Benefit" in cash equal to two (2) times Employee's
               Base Compensation as of the date of such termination.

          Such payment shall be made within thirty (30) days following said
     termination.

                            INTERCREDITOR AGREEMENT

     THIS INTERCREDITOR AGREEMENT (the "Agreement") dated as of ___________,
                                        ---------
1999 is entered into among MIDDLE BAY OIL COMPANY, INC. ("Borrower"),  BANK ONE,
                                                          --------
TEXAS, N.A., as agent for any holder of a Note under the Senior Loan Agreement
("Senior Lender") and 3TEC ENERGY CORPORATION ("Subordinated Lender").
  -------------                                 -------------------

                              W I T N E S S E T H:

     WHEREAS, Borrower, the Lenders under the Senior Loan Agreement (the
"Lenders") and Senior Lender entered into that certain Restated Credit Agreement
 -------
dated of even date herewith (the "Senior Loan Agreement") pursuant to which the
                                  ---------------------
Lenders agreed to provide Borrower with a $250,000,000 revolving credit
facility; and

     WHEREAS, Borrower and Subordinated Lender entered into a Securities
Purchase Agreement dated July 1, 1999 (the "Subordinated Loan Agreement"),
                                            ---------------------------
pursuant to which Borrower issued and Subordinated Lender purchased a certain
$10,700,000 Senior Subordinated Note dated August 27, 1999 (the "Subordinated
                                                                 ------------
Note"); and
- ----

     WHEREAS, the indebtedness evidenced by the Subordinated Note and all
obligations of Borrower under the Subordinated Loan Agreement are herein called
the "Subordinated Debt;" and
     -----------------

     WHEREAS, to induce the Lenders and the Senior Lender to enter into the
Senior Loan Agreement, the Borrower and the Subordinated Lender have agreed to
enter into this Agreement with the Senior Lender to subordinate the rights of
the Subordinated Lender to the rights of the Lenders and the Senior Lender as
provided herein.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

     1.   Subordination of Subordinated Debt.  The payment of the Subordinated
          -----------------------------------
Debt is expressly subordinated to the prior payment in full in cash of the
Senior Debt to the extent and in the manner set forth in this Agreement.  Except
as provided in Section 3 and Section 4 of this Agreement, the Borrower and
Subordinated Lender hereby postpone and subordinate the Subordinated Debt to all
Senior Debt.  The Borrower and Subordinated Lender agree that so long as the
Senior Loan Agreement is in effect and thereafter until the Senior Debt is paid
in full in cash and, except as provided in Section 3 and Section 4 of this
Agreement, Subordinated Lender will not demand, take or receive from the
Borrower, in cash or property or by set-off or in any other manner, payment of
or on account of, and the Borrower will not pay, the whole or any part of the

INTERCREDITOR AGREEMENT - Page 1
<PAGE>

Subordinated Debt.  As used herein, the term "Senior Debt" shall include any and
                                              -----------
all obligations owed to the Lenders and the Senior Lender by Borrower pursuant
to the Senior Loan Agreement and the Notes issued in connection therewith,
including principal, interest, post-petition interest during any bankruptcy
proceeding (whether or not allowed or allowable by a court), fees, expenses,
obligations on letters of credit, obligations relating to derivatives and any
other amount due or to become due under the Senior Loan Agreement and Notes.
Subordinated Lender expressly acknowledging that such Senior Debt includes
indebtedness between the Borrower and the Lenders or the Senior Lender hereafter
created or arising under the Senior Loan Agreement, and any and all renewals and
extensions of all or any part of such indebtedness and liabilities.

     2.   Security for Subordinated Debt.  The parties agree that the
          -------------------------------
Subordinated Debt shall be unsecured.

     3.   Payment of Credit Interest on Subordinated Debt.  The provisions of
          ------------------------------------------------
Section 1 hereof notwithstanding, the Borrower may pay and Subordinated Lender
may receive the interest  (the "Credit Interest") which is due and payable on
                                ---------------
the Subordinated Debt if (a) the full payment of all amounts then due and
payable on the Senior Debt have been made or duly provided for in accordance
with the Senior Loan Agreement, and (b) a Subordination Event (as defined below)
has not occurred or would not occur as a result of such payment.  Upon the
occurrence of a Subordination Event, all claims of Subordinated Lender to the
Credit Interest shall be subordinated to the prior payment in full of the Senior
Debt, and all further payments of Credit Interest to Subordinated Lender shall
immediately cease.  After the occurrence of a Subordination Event, the payment
of Credit Interest by the Borrower to Subordinated Lender may resume only if the
Subordination Event has been cured to the satisfaction of the Senior Lender or
waived in writing by Senior Lender (which waiver includes an express permission
to pay such Credit Interest). "Subordination Event" means the occurrence of
                               -------------------
either (a) a Default or Event of Default for which Senior Lender has sent
written notice of such Default or Event of Default (other than an Event of
Default specified in Section 14(f) or (g) of the Senior Credit Agreement for
which no such notice need be sent) to Borrower (a "Default Notice") or (b) a
                                                   --------------
Borrowing Base deficiency under the Senior Loan Agreement.  Notwithstanding the
above, if within one hundred eight (180) days after the sending of such Default
Notice by Senior Lender such Default or Event of Default has not become the
subject of (a) judicial proceedings or (b) an acceleration notice by Senior
Lender, then Borrower (unless in such interval the provisions of this Section 3
have come into effect on account of any other Default or Event of Default that
did not exist on the date of any prior Default Notice) shall resume paying, and
Subordinated Lender shall be entitled to receive, Credit Interest until such
time (if any) that such judicial proceedings are instituted, such acceleration
notice is given or a Default Notice (on account of any other Default or Event of
Default) is given and a period of one hundred eighty (180) days shall not have
elapsed since the giving of such Default Notice as contemplated above.

     4.   Prepayment of Principal on the Subordinated Debt.  The provisions of
          -------------------------------------------------
Section 1 hereof notwithstanding, a part or all of the principal balance of the
Subordinated Debt may be paid (the "Note Payment"), (a) if the Senior Debt has
been paid in full in cash and all commitments of the

INTERCREDITOR AGREEMENT - Page 2
<PAGE>

Banks under the Senior Loan Agreement to make advances or lend money have
terminated, or (b) with the prior written consent of the Lenders.

     5.   Restriction on Other Actions.  Prior to the payment in full in cash of
          ----------------------------
the Senior Debt and the termination of all commitments of the Lenders under the
Senior Loan Agreement, Subordinated Lender shall not take any action to declare
the Subordinated Note due or in default, collect or accelerate the Subordinated
Debt or exercise any remedies in respect of the Subordinated Debt set forth in
the Subordinated Loan Agreement or that may otherwise be available to
Subordinated Lender, either at law or in equity, including but not limited to
initiating any plan or proceeding pursuant to any bankruptcy, insolvency, or
receivership proceeding, or seeking an assignment for the benefit of creditors
or the marshalling of the assets and liability of the Borrower.

     6.   Proof of Claim/Power of Attorney.  In the event of any liquidation,
          ---------------------------------
conservatorship, bankruptcy, reorganization, rearrangement, debtor's relief, or
other insolvency proceedings affecting the Borrower, the Subordinated Lender
will at the Senior Lender's request and at Subordinated Lender's expense file
any claims, proofs of claim, or other instruments of similar character necessary
to enforce the obligations of the Borrower in respect of the Subordinated Debt
and will hold in trust for the Senior Lender and pay over to the Senior Lender,
in the form received, to be applied on the Senior Debt, any and all moneys,
dividends, or other assets received in any such proceedings on account of the
Subordinated Debt, unless and until the Senior Debt shall be paid in full.

     7.   Payments Held in Trust.  Except to the extent that Credit Interest is
          -----------------------
permitted to be paid to Subordinated Lender pursuant to the terms of Section 3
hereof or a Note Payment is permitted to be paid to Subordinated Lender pursuant
to the terms of Section 4 hereof, should Subordinated Lender receive any payment
or distribution from the Borrower upon or with respect to the Subordinated Debt,
Subordinated Lender will forthwith deliver the same to the Senior Lender, in
precisely the form received (except for endorsement or assignment of
Subordinated Lender where necessary), for application on the Senior Debt and,
until so delivered, the same shall be held in trust by Subordinated Lender as
the Senior Lender's property.  In the event of the failure of Subordinated
Lender to make any such endorsement or assignment, the Agent is hereby
irrevocably authorized to make the same.

     8.   No Modification of Subordinated Debt.  The Borrower and Subordinated
          -------------------------------------
Lender agree not to renew, extend, modify or amend in any material respect the
Subordinated Debt or any instrument or agreement documenting or securing the
Subordinated Debt without the prior written consent of the Senior Lender.
Notwithstanding the foregoing, Borrower may, without the consent of Senior
Lender, (a) extend the date on which payments are required under the
Subordinated Note, (b) reduce the interest rate applicable to the Subordinated
Note, (c) waive compliance with the terms of the Subordinated Note or loan
documents associated therewith or any default arising from non-compliance or (d)
relax or make less restrictive any covenant in the Subordinated Note or loan
documents associated therewith.  Notwithstanding any provision of this Agreement
to the contrary,

INTERCREDITOR AGREEMENT - Page 3
<PAGE>

(i) Subordinated Lender may convert the Subordinated Note or a portion of such
note into shares of common stock of Borrower at any time in accordance with the
terms of such note, and (ii) the holder of a stock purchase warrant issued
pursuant to the Subordinated Loan Agreement may exercise any such warrant, in
whole or in part, for shares of common stock of Borrower in accordance with the
terms of such warranty (provided such exercise shall not involve the payment of
any cash by Borrower).

     9.   Waivers and Consents.  The Senior Lender, the Lenders and Borrower may
          ---------------------
at any time and from time to time extend, renew or otherwise alter, as the
Senior Lender and Borrower may deem proper, the terms of any or all of the
Senior Debt or of any security therefor or of any agreement providing therefor
or relating to the Senior Debt or to such security, or accelerate the maturity
of any or all of the Senior Debt in accordance with the terms thereof or of any
agreement among the Senior Lender, the Lenders and Borrower, and the Senior
Lender may exchange, sell, surrender, release, fail to resort to or realize upon
or otherwise deal with any or all security for the Senior Debt, or release or
fail to resort to or enforce guaranties or endorsements of, or of the
liabilities of any obligors liable upon, the Senior Debt or release or fail to
set-off any balance of funds of the Borrower with the Senior Lender or under the
Senior Lender's control, and generally deal with the Borrower and all guarantors
and endorsers of, and all obligors liable upon, the Senior Debt, as the Senior
Lender sees fit, all without notice to or consent of Subordinated Lender and
without affecting to any extent any obligation or liability of Subordinated
Lender, or any of the Senior Lenders' or any Lender's rights, hereunder.
Without in any way limiting the foregoing, Subordinated Lender understands and
agrees that the Senior Lender shall have uncontrolled power and discretion,
without notice to Subordinated Lender, to deal in any manner with any
indebtedness, interest, cost and expenses payable by or liability of the
Borrower to the Lenders or the Senior Lender and any security or guaranties
therefor.  Subordinated Lender hereby waives and agrees not to assert against
the Senior Lender or any Lender any rights which a guarantor or surety could
exercise, and nothing in this Agreement shall be deemed to constitute
Subordinated Lender as a guarantor or a surety.  Subordinated Lender further
consents and agrees to any action taken or omitted to be taken with respect to
the Senior Loan Agreement, the Senior Loan Documents, the Senior Debt, and the
security and collateral therefor, whether or not such action or omission
prejudices Subordinated Lender or increases the likelihood that the Subordinated
Debt will not be paid, and whether or not such circumstance might otherwise
constitute a defense available to, or a discharge of, the Borrower or
Subordinated Lender.

     10.  Subrogation.  No payment or distribution to the Senior Lender pursuant
          -----------
to the provisions of this Agreement shall entitle Subordinated Lender to
exercise any rights of subrogation in respect hereof until all of the Senior
Debt shall have been irrevocably and unconditionally paid in full in cash.

     11.  Further Assurances.  The Borrower and Subordinated Lender agree that
          -------------------
any note representing the Subordinated Debt shall be stamped with a statement
referring to the existence of this Agreement.  The Borrower and Subordinated
Lender each will, at its expense and from time to

INTERCREDITOR AGREEMENT - Page 4
<PAGE>

time, promptly execute and deliver all further instruments and documents, and
take all further action that may be necessary or desirable, or that the Senior
Lender may reasonably request, in order to protect any right or interest granted
or purported to be granted hereby or to enable the Senior Lender to exercise and
enforce its rights and remedies hereunder.

     12.  Representations.  Subordinated Lender warrants and represents to the
          ----------------
Senior Lender that (a) it has the power and authority to execute, deliver and
carry out the terms of this Agreement, (b) it has taken all necessary action to
authorize the execution and delivery of this Agreement, (c) this Agreement has
been duly executed and delivered by Subordinated Lender and constitutes the
legal, valid and binding obligation of Subordinated Lender enforceable in
accordance with its terms except to the extent that the enforcement thereof may
be limited by applicable bankruptcy, insolvency, reorganization or other similar
laws affecting the enforcement of creditors' rights generally, and (d) attached
hereto as Exhibit "A" is a true and correct copy of the Subordinated Note.
          -----------

     13.  Costs and Expenses.  Borrower agrees to pay, on demand, to the Senior
          -------------------
Lender all costs and expenses (including court costs and reasonable attorneys'
fees) incurred by any Lenders or the Senior Lender in the enforcement of this
Agreement.

     14.  Binding Effect.  This Agreement shall be immediately binding on the
          ---------------
Senior Lender, Borrower and Subordinated Lender and the successors and assigns
of the Senior Lender, the Lenders, Borrower and Subordinated Lender, and the
covenants of Subordinated Lender and the Borrower in favor of the Senior Lender
and the Lenders contained herein shall extend to, include, and be enforceable
by, any transferee, assignee, or endorsee of the Senior Lender or the Lenders of
any of the Senior Debt.

     15.  Governing Law.  This Agreement shall be governed by, and construed in
          --------------
accordance with, the laws of the State of Texas and is performable in Dallas
County, Texas.

     16.  Counterparts.  This Agreement may be executed in counterparts, each of
          ------------
which shall be deemed to be an original for all purposes.

     17.  Defined Terms.  Unless otherwise defined herein, terms used herein are
          -------------
used as defined in the Senior Loan Agreement.

     18.  THIS INTERCREDITOR AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN
THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

                              W I T N E S S E T H:

     WHEREAS, Borrower, the Lenders under the Senior Loan Agreement (the
"Lenders") and Senior Lender entered into that certain Restated Credit Agreement
 -------
dated of even date herewith (the "Senior Loan Agreement") pursuant to which the
                                  ---------------------
Lenders agreed to provide Borrower with a $250,000,000 revolving credit
facility; and

     WHEREAS, Borrower and Subordinated Lender entered into a Securities
Purchase Agreement dated July 1, 1999 (the "Subordinated Loan Agreement"),
                                            ---------------------------
pursuant to which Borrower issued and Subordinated Lender purchased a certain
$10,700,000 Senior Subordinated Note dated August 27, 1999 (the "Subordinated
                                                                 ------------
Note"); and
- ----

     WHEREAS, the indebtedness evidenced by the Subordinated Note and all
obligations of Borrower under the Subordinated Loan Agreement are herein called
the "Subordinated Debt;" and
     -----------------

     WHEREAS, to induce the Lenders and the Senior Lender to enter into the
Senior Loan Agreement, the Borrower and the Subordinated Lender have agreed to
enter into this Agreement with the Senior Lender to subordinate the rights of
the Subordinated Lender to the rights of the Lenders and the Senior Lender as
provided herein.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

     1.   Subordination of Subordinated Debt.  The payment of the Subordinated
          -----------------------------------
Debt is expressly subordinated to the prior payment in full in cash of the
Senior Debt to the extent and in the manner set forth in this Agreement.  Except
as provided in Section 3 and Section 4 of this Agreement, the Borrower and
Subordinated Lender hereby postpone and subordinate the Subordinated Debt to all
Senior Debt.  The Borrower and Subordinated Lender agree that so long as the
Senior Loan Agreement is in effect and thereafter until the Senior Debt is paid
in full in cash and, except as provided in Section 3 and Section 4 of this
Agreement, Subordinated Lender will not demand, take or receive from the
Borrower, in cash or property or by set-off or in any other manner, payment of
or on account of, and the Borrower will not pay, the whole or any part of the

INTERCREDITOR AGREEMENT - Page 1
<PAGE>

Subordinated Debt.  As used herein, the term "Senior Debt" shall include any and
                                              -----------
all obligations owed to the Lenders and the Senior Lender by Borrower pursuant
to the Senior Loan Agreement and the Notes issued in connection therewith,
including principal, interest, post-petition interest during any bankruptcy
proceeding (whether or not allowed or allowable by a court), fees, expenses,
obligations on letters of credit, obligations relating to derivatives and any
other amount due or to become due under the Senior Loan Agreement and Notes.
Subordinated Lender expressly acknowledging that such Senior Debt includes
indebtedness between the Borrower and the Lenders or the Senior Lender hereafter
created or arising under the Senior Loan Agreement, and any and all renewals and
extensions of all or any part of such indebtedness and liabilities.

     2.   Security for Subordinated Debt.  The parties agree that the
          -------------------------------
Subordinated Debt shall be unsecured.

     3.   Payment of Credit Interest on Subordinated Debt.  The provisions of
          ------------------------------------------------
Section 1 hereof notwithstanding, the Borrower may pay and Subordinated Lender
may receive the interest  (the "Credit Interest") which is due and payable on
                                ---------------
the Subordinated Debt if (a) the full payment of all amounts then due and
payable on the Senior Debt have been made or duly provided for in accordance
with the Senior Loan Agreement, and (b) a Subordination Event (as defined below)
has not occurred or would not occur as a result of such payment.  Upon the
occurrence of a Subordination Event, all claims of Subordinated Lender to the
Credit Interest shall be subordinated to the prior payment in full of the Senior
Debt, and all further payments of Credit Interest to Subordinated Lender shall
immediately cease.  After the occurrence of a Subordination Event, the payment
of Credit Interest by the Borrower to Subordinated Lender may resume only if the
Subordination Event has been cured to the satisfaction of the Senior Lender or
waived in writing by Senior Lender (which waiver includes an express permission
to pay such Credit Interest). "Subordination Event" means the occurrence of
                               -------------------
either (a) a Default or Event of Default for which Senior Lender has sent
written notice of such Default or Event of Default (other than an Event of
Default specified in Section 14(f) or (g) of the Senior Credit Agreement for
which no such notice need be sent) to Borrower (a "Default Notice") or (b) a
                                                   --------------
Borrowing Base deficiency under the Senior Loan Agreement.  Notwithstanding the
above, if within one hundred eight (180) days after the sending of such Default
Notice by Senior Lender such Default or Event of Default has not become the
subject of (a) judicial proceedings or (b) an acceleration notice by Senior
Lender, then Borrower (unless in such interval the provisions of this Section 3
have come into effect on account of any other Default or Event of Default that
did not exist on the date of any prior Default Notice) shall resume paying, and
Subordinated Lender shall be entitled to receive, Credit Interest until such
time (if any) that such judicial proceedings are instituted, such acceleration
notice is given or a Default Notice (on account of any other Default or Event of
Default) is given and a period of one hundred eighty (180) days shall not have
elapsed since the giving of such Default Notice as contemplated above.

     4.   Prepayment of Principal on the Subordinated Debt.  The provisions of
          -------------------------------------------------
Section 1 hereof notwithstanding, a part or all of the principal balance of the
Subordinated Debt may be paid (the "Note Payment"), (a) if the Senior Debt has
been paid in full in cash and all commitments of the

INTERCREDITOR AGREEMENT - Page 2
<PAGE>

Banks under the Senior Loan Agreement to make advances or lend money have
terminated, or (b) with the prior written consent of the Lenders.


     5.   Restriction on Other Actions.  Prior to the payment in full in cash of
          -----------------------------
the Senior Debt and the termination of all commitments of the Lenders under the
Senior Loan Agreement, Subordinated Lender shall not take any action to declare
the Subordinated Note due or in default, collect or accelerate the Subordinated
Debt or exercise any remedies in respect of the Subordinated Debt set forth in
the Subordinated Loan Agreement or that may otherwise be available to
Subordinated Lender, either at law or in equity, including but not limited to
initiating any plan or proceeding pursuant to any bankruptcy, insolvency, or
receivership proceeding, or seeking an assignment for the benefit of creditors
or the marshalling of the assets and liability of the Borrower.

     6.   Proof of Claim/Power of Attorney.  In the event of any liquidation,
          ---------------------------------
conservatorship, bankruptcy, reorganization, rearrangement, debtor's relief, or
other insolvency proceedings affecting the Borrower, the Subordinated Lender
will at the Senior Lender's request and at Subordinated Lender's expense file
any claims, proofs of claim, or other instruments of similar character necessary
to enforce the obligations of the Borrower in respect of the Subordinated Debt
and will hold in trust for the Senior Lender and pay over to the Senior Lender,
in the form received, to be applied on the Senior Debt, any and all moneys,
dividends, or other assets received in any such proceedings on account of the
Subordinated Debt, unless and until the Senior Debt shall be paid in full.

     7.   Payments Held in Trust.  Except to the extent that Credit Interest is
          -----------------------
permitted to be paid to Subordinated Lender pursuant to the terms of Section 3
hereof or a Note Payment is permitted to be paid to Subordinated Lender pursuant
to the terms of Section 4 hereof, should Subordinated Lender receive any payment
or distribution from the Borrower upon or with respect to the Subordinated Debt,
Subordinated Lender will forthwith deliver the same to the Senior Lender, in
precisely the form received (except for endorsement or assignment of
Subordinated Lender where necessary), for application on the Senior Debt and,
until so delivered, the same shall be held in trust by Subordinated Lender as
the Senior Lender's property.  In the event of the failure of Subordinated
Lender to make any such endorsement or assignment, the Agent is hereby
irrevocably authorized to make the same.

     8.   No Modification of Subordinated Debt.  The Borrower and Subordinated
          -------------------------------------
Lender agree not to renew, extend, modify or amend in any material respect the
Subordinated Debt or any instrument or agreement documenting or securing the
Subordinated Debt without the prior written consent of the Senior Lender.
Notwithstanding the foregoing, Borrower may, without the consent of Senior
Lender, (a) extend the date on which payments are required under the
Subordinated Note, (b) reduce the interest rate applicable to the Subordinated
Note, (c) waive compliance with the terms of the Subordinated Note or loan
documents associated therewith or any default arising from non-compliance or (d)
relax or make less restrictive any covenant in the Subordinated Note or loan
documents associated therewith.  Notwithstanding any provision of this Agreement
to the contrary,

INTERCREDITOR AGREEMENT - Page 3
<PAGE>

(i) Subordinated Lender may convert the Subordinated Note or a portion of such
note into shares of common stock of Borrower at any time in accordance with the
terms of such note, and (ii) the holder of a stock purchase warrant issued
pursuant to the Subordinated Loan Agreement may exercise any such warrant, in
whole or in part, for shares of common stock of Borrower in accordance with the
terms of such warranty (provided such exercise shall not involve the payment of
any cash by Borrower).

     9.   Waivers and Consents.  The Senior Lender, the Lenders and Borrower may
          ---------------------
at any time and from time to time extend, renew or otherwise alter, as the
Senior Lender and Borrower may deem proper, the terms of any or all of the
Senior Debt or of any security therefor or of any agreement providing therefor
or relating to the Senior Debt or to such security, or accelerate the maturity
of any or all of the Senior Debt in accordance with the terms thereof or of any
agreement among the Senior Lender, the Lenders and Borrower, and the Senior
Lender may exchange, sell, surrender, release, fail to resort to or realize upon
or otherwise deal with any or all security for the Senior Debt, or release or
fail to resort to or enforce guaranties or endorsements of, or of the
liabilities of any obligors liable upon, the Senior Debt or release or fail to
set-off any balance of funds of the Borrower with the Senior Lender or under the
Senior Lender's control, and generally deal with the Borrower and all guarantors
and endorsers of, and all obligors liable upon, the Senior Debt, as the Senior
Lender sees fit, all without notice to or consent of Subordinated Lender and
without affecting to any extent any obligation or liability of Subordinated
Lender, or any of the Senior Lenders' or any Lender's rights, hereunder.
Without in any way limiting the foregoing, Subordinated Lender understands and
agrees that the Senior Lender shall have uncontrolled power and discretion,
without notice to Subordinated Lender, to deal in any manner with any
indebtedness, interest, cost and expenses payable by or liability of the
Borrower to the Lenders or the Senior Lender and any security or guaranties
therefor.  Subordinated Lender hereby waives and agrees not to assert against
the Senior Lender or any Lender any rights which a guarantor or surety could
exercise, and nothing in this Agreement shall be deemed to constitute
Subordinated Lender as a guarantor or a surety.  Subordinated Lender further
consents and agrees to any action taken or omitted to be taken with respect to
the Senior Loan Agreement, the Senior Loan Documents, the Senior Debt, and the
security and collateral therefor, whether or not such action or omission
prejudices Subordinated Lender or increases the likelihood that the Subordinated
Debt will not be paid, and whether or not such circumstance might otherwise
constitute a defense available to, or a discharge of, the Borrower or
Subordinated Lender.

     10.  Subrogation.  No payment or distribution to the Senior Lender pursuant
          ------------
to the provisions of this Agreement shall entitle Subordinated Lender to
exercise any rights of subrogation in respect hereof until all of the Senior
Debt shall have been irrevocably and unconditionally paid in full in cash.

     11.  Further Assurances.  The Borrower and Subordinated Lender agree that
          -------------------
any note representing the Subordinated Debt shall be stamped with a statement
referring to the existence of this Agreement.  The Borrower and Subordinated
Lender each will, at its expense and from time to

INTERCREDITOR AGREEMENT - Page 4
<PAGE>

time, promptly execute and deliver all further instruments and documents, and
take all further action that may be necessary or desirable, or that the Senior
Lender may reasonably request, in order to protect any right or interest granted
or purported to be granted hereby or to enable the Senior Lender to exercise and
enforce its rights and remedies hereunder.

     12.  Representations.  Subordinated Lender warrants and represents to the
          ----------------
Senior Lender that (a) it has the power and authority to execute, deliver and
carry out the terms of this Agreement, (b) it has taken all necessary action to
authorize the execution and delivery of this Agreement, (c) this Agreement has
been duly executed and delivered by Subordinated Lender and constitutes the
legal, valid and binding obligation of Subordinated Lender enforceable in
accordance with its terms except to the extent that the enforcement thereof may
be limited by applicable bankruptcy, insolvency, reorganization or other similar
laws affecting the enforcement of creditors' rights generally, and (d) attached
hereto as Exhibit "A" is a true and correct copy of the Subordinated Note.
          -----------

     13.  Costs and Expenses.  Borrower agrees to pay, on demand, to the Senior
          -------------------
Lender all costs and expenses (including court costs and reasonable attorneys'
fees) incurred by any Lenders or the Senior Lender in the enforcement of this
Agreement.

     14.  Binding Effect.  This Agreement shall be immediately binding on the
          ---------------
Senior Lender, Borrower and Subordinated Lender and the successors and assigns
of the Senior Lender, the Lenders, Borrower and Subordinated Lender, and the
covenants of Subordinated Lender and the Borrower in favor of the Senior Lender
and the Lenders contained herein shall extend to, include, and be enforceable
by, any transferee, assignee, or endorsee of the Senior Lender or the Lenders of
any of the Senior Debt.

     15.  Governing Law.  This Agreement shall be governed by, and construed in
          --------------
accordance with, the laws of the State of Texas and is performable in Dallas
County, Texas.

     16.  Counterparts.  This Agreement may be executed in counterparts, each of
          -------------
which shall be deemed to be an original for all purposes.

     17.  Defined Terms.  Unless otherwise defined herein, terms used herein are
          --------------
used as defined in the Senior Loan Agreement.

     18.  THIS INTERCREDITOR AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN
THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

pursuant to which Borrower issued and Subordinated Lender purchased a certain
$10,700,000 Senior Subordinated Note dated August 27, 1999 (the "Subordinated
                                                                 ------------

Senior Loan Agreement, the Borrower and the Subordinated Lender have agreed to
enter into this Agreement with the Senior Lender to subordinate the rights of
the Subordinated Lender to the rights of the Lenders and the Senior Lender as
provided herein.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

     1.   Subordination of Subordinated Debt.  The payment of the Subordinated
          -----------------------------------
Debt is expressly subordinated to the prior payment in full in cash of the
Senior Debt to the extent and in the manner set forth in this Agreement.  Except
as provided in Section 3 and Section 4 of this Agreement, the Borrower and
Subordinated Lender hereby postpone and subordinate the Subordinated Debt to all
Senior Debt.  The Borrower and Subordinated Lender agree that so long as the
Senior Loan Agreement is in effect and thereafter until the Senior Debt is paid

Subordinated Debt.  As used herein, the term "Senior Debt" shall include any and
                                              -----------
all obligations owed to the Lenders and the Senior Lender by Borrower pursuant
to the Senior Loan Agreement and the Notes issued in connection therewith,
including principal, interest, post-petition interest during any bankruptcy
proceeding (whether or not allowed or allowable by a court), fees, expenses,
obligations on letters of credit, obligations relating to derivatives and any
other amount due or to become due under the Senior Loan Agreement and Notes.
Subordinated Lender expressly acknowledging that such Senior Debt includes
indebtedness between the Borrower and the Lenders or the Senior Lender hereafter
created or arising under the Senior Loan Agreement, and any and all renewals and
extensions of all or any part of such indebtedness and liabilities.

     2.   Security for Subordinated Debt.  The parties agree that the
          -------------------------------
Subordinated Debt shall be unsecured.

     3.   Payment of Credit Interest on Subordinated Debt.  The provisions of
          ------------------------------------------------
Section 1 hereof notwithstanding, the Borrower may pay and Subordinated Lender
may receive the interest  (the "Credit Interest") which is due and payable on
                                ---------------
the Subordinated Debt if (a) the full payment of all amounts then due and
payable on the Senior Debt have been made or duly provided for in accordance
with the Senior Loan Agreement, and (b) a Subordination Event (as defined below)
has not occurred or would not occur as a result of such payment.  Upon the
occurrence of a Subordination Event, all claims of Subordinated Lender to the
Credit Interest shall be subordinated to the prior payment in full of the Senior
Debt, and all further payments of Credit Interest to Subordinated Lender shall
immediately cease.  After the occurrence of a Subordination Event, the payment
of Credit Interest by the Borrower to Subordinated Lender may resume only if the
Subordination Event has been cured to the satisfaction of the Senior Lender or
waived in writing by Senior Lender (which waiver includes an express permission
to pay such Credit Interest). "Subordination Event" means the occurrence of
                               -------------------
either (a) a Default or Event of Default for which Senior Lender has sent
written notice of such Default or Event of Default (other than an Event of
Default specified in Section 14(f) or (g) of the Senior Credit Agreement for
which no such notice need be sent) to Borrower (a "Default Notice") or (b) a
                                                   --------------

above, if within one hundred eight (180) days after the sending of such Default
Notice by Senior Lender such Default or Event of Default has not become the
subject of (a) judicial proceedings or (b) an acceleration notice by Senior
Lender, then Borrower (unless in such interval the provisions of this Section 3
have come into effect on account of any other Default or Event of Default that
did not exist on the date of any prior Default Notice) shall resume paying, and
Subordinated Lender shall be entitled to receive, Credit Interest until such
time (if any) that such judicial proceedings are instituted, such acceleration
notice is given or a Default Notice (on account of any other Default or Event of
Default) is given and a period of one hundred eighty (180) days shall not have
elapsed since the giving of such Default Notice as contemplated above.

     4.   Prepayment of Principal on the Subordinated Debt.  The provisions of
          -------------------------------------------------
Section 1 hereof notwithstanding, a part or all of the principal balance of the
Subordinated Debt may be paid (the "Note Payment"), (a) if the Senior Debt has
been paid in full in cash and all commitments of the

Banks under the Senior Loan Agreement to make advances or lend money have
terminated, or (b) with the prior written consent of the Lenders.

     5.   Restriction on Other Actions.  Prior to the payment in full in cash of
          ----------------------------
the Senior Debt and the termination of all commitments of the Lenders under the
Senior Loan Agreement, Subordinated Lender shall not take any action to declare
the Subordinated Note due or in default, collect or accelerate the Subordinated
Debt or exercise any remedies in respect of the Subordinated Debt set forth in
the Subordinated Loan Agreement or that may otherwise be available to
Subordinated Lender, either at law or in equity, including but not limited to
initiating any plan or proceeding pursuant to any bankruptcy, insolvency, or
receivership proceeding, or seeking an assignment for the benefit of creditors
or the marshalling of the assets and liability of the Borrower.

     6.   Proof of Claim/Power of Attorney.  In the event of any liquidation,
          ---------------------------------
conservatorship, bankruptcy, reorganization, rearrangement, debtor's relief, or
other insolvency proceedings affecting the Borrower, the Subordinated Lender
will at the Senior Lender's request and at Subordinated Lender's expense file
any claims, proofs of claim, or other instruments of similar character necessary
to enforce the obligations of the Borrower in respect of the Subordinated Debt
and will hold in trust for the Senior Lender and pay over to the Senior Lender,
in the form received, to be applied on the Senior Debt, any and all moneys,
dividends, or other assets received in any such proceedings on account of the
Subordinated Debt, unless and until the Senior Debt shall be paid in full.

     7.   Payments Held in Trust.  Except to the extent that Credit Interest is
          -----------------------
permitted to be paid to Subordinated Lender pursuant to the terms of Section 3
hereof or a Note Payment is permitted to be paid to Subordinated Lender pursuant
to the terms of Section 4 hereof, should Subordinated Lender receive any payment
or distribution from the Borrower upon or with respect to the Subordinated Debt,
Subordinated Lender will forthwith deliver the same to the Senior Lender, in
precisely the form received (except for endorsement or assignment of
Subordinated Lender where necessary), for application on the Senior Debt and,
until so delivered, the same shall be held in trust by Subordinated Lender as
the Senior Lender's property.  In the event of the failure of Subordinated
Lender to make any such endorsement or assignment, the Agent is hereby
irrevocably authorized to make the same.

     8.   No Modification of Subordinated Debt.  The Borrower and Subordinated
          -------------------------------------
Lender agree not to renew, extend, modify or amend in any material respect the
Subordinated Debt or any instrument or agreement documenting or securing the
Subordinated Debt without the prior written consent of the Senior Lender.
Notwithstanding the foregoing, Borrower may, without the consent of Senior
Lender, (a) extend the date on which payments are required under the
Subordinated Note, (b) reduce the interest rate applicable to the Subordinated
Note, (c) waive compliance with the terms of the Subordinated Note or loan
documents associated therewith or any default arising from non-compliance or (d)
relax or make less restrictive any covenant in the Subordinated Note or loan
documents associated therewith.  Notwithstanding any provision of this Agreement
to the contrary,

INTERCREDITOR AGREEMENT - Page 3
<PAGE>

(i) Subordinated Lender may convert the Subordinated Note or a portion of such
note into shares of common stock of Borrower at any time in accordance with the
terms of such note, and (ii) the holder of a stock purchase warrant issued
pursuant to the Subordinated Loan Agreement may exercise any such warrant, in
whole or in part, for shares of common stock of Borrower in accordance with the
terms of such warranty (provided such exercise shall not involve the payment of
any cash by Borrower).

     9.   Waivers and Consents.  The Senior Lender, the Lenders and Borrower may
          ---------------------
at any time and from time to time extend, renew or otherwise alter, as the
Senior Lender and Borrower may deem proper, the terms of any or all of the
Senior Debt or of any security therefor or of any agreement providing therefor
or relating to the Senior Debt or to such security, or accelerate the maturity
of any or all of the Senior Debt in accordance with the terms thereof or of any
agreement among the Senior Lender, the Lenders and Borrower, and the Senior
Lender may exchange, sell, surrender, release, fail to resort to or realize upon
or otherwise deal with any or all security for the Senior Debt, or release or
fail to resort to or enforce guaranties or endorsements of, or of the
liabilities of any obligors liable upon, the Senior Debt or release or fail to
set-off any balance of funds of the Borrower with the Senior Lender or under the
Senior Lender's control, and generally deal with the Borrower and all guarantors
and endorsers of, and all obligors liable upon, the Senior Debt, as the Senior
Lender sees fit, all without notice to or consent of Subordinated Lender and
without affecting to any extent any obligation or liability of Subordinated
Lender, or any of the Senior Lenders' or any Lender's rights, hereunder.
Without in any way limiting the foregoing, Subordinated Lender understands and
agrees that the Senior Lender shall have uncontrolled power and discretion,
without notice to Subordinated Lender, to deal in any manner with any
indebtedness, interest, cost and expenses payable by or liability of the
Borrower to the Lenders or the Senior Lender and any security or guaranties
therefor.  Subordinated Lender hereby waives and agrees not to assert against
the Senior Lender or any Lender any rights which a guarantor or surety could
exercise, and nothing in this Agreement shall be deemed to constitute
Subordinated Lender as a guarantor or a surety.  Subordinated Lender further
consents and agrees to any action taken or omitted to be taken with respect to
the Senior Loan Agreement, the Senior Loan Documents, the Senior Debt, and the
security and collateral therefor, whether or not such action or omission
prejudices Subordinated Lender or increases the likelihood that the Subordinated
Debt will not be paid, and whether or not such circumstance might otherwise
constitute a defense available to, or a discharge of, the Borrower or
Subordinated Lender.

     10.  Subrogation.  No payment or distribution to the Senior Lender pursuant
          -----------
to the provisions of this Agreement shall entitle Subordinated Lender to
exercise any rights of subrogation in respect hereof until all of the Senior
Debt shall have been irrevocably and unconditionally paid in full in cash.

     11.  Further Assurances.  The Borrower and Subordinated Lender agree that
          -------------------
any note representing the Subordinated Debt shall be stamped with a statement
referring to the existence of this Agreement.  The Borrower and Subordinated
Lender each will, at its expense and from time to

INTERCREDITOR AGREEMENT - Page 4
<PAGE>

time, promptly execute and deliver all further instruments and documents, and
take all further action that may be necessary or desirable, or that the Senior
Lender may reasonably request, in order to protect any right or interest granted
or purported to be granted hereby or to enable the Senior Lender to exercise and
enforce its rights and remedies hereunder.

     12.  Representations.  Subordinated Lender warrants and represents to the
          ----------------
Senior Lender that (a) it has the power and authority to execute, deliver and
carry out the terms of this Agreement, (b) it has taken all necessary action to
authorize the execution and delivery of this Agreement, (c) this Agreement has
been duly executed and delivered by Subordinated Lender and constitutes the
legal, valid and binding obligation of Subordinated Lender enforceable in
accordance with its terms except to the extent that the enforcement thereof may
be limited by applicable bankruptcy, insolvency, reorganization or other similar
laws affecting the enforcement of creditors' rights generally, and (d) attached
hereto as Exhibit "A" is a true and correct copy of the Subordinated Note.
          -----------

     13.  Costs and Expenses.  Borrower agrees to pay, on demand, to the Senior
          -------------------
Lender all costs and expenses (including court costs and reasonable attorneys'
fees) incurred by any Lenders or the Senior Lender in the enforcement of this
Agreement.

     14.  Binding Effect.  This Agreement shall be immediately binding on the
          ---------------
Senior Lender, Borrower and Subordinated Lender and the successors and assigns
of the Senior Lender, the Lenders, Borrower and Subordinated Lender, and the
covenants of Subordinated Lender and the Borrower in favor of the Senior Lender
and the Lenders contained herein shall extend to, include, and be enforceable
by, any transferee, assignee, or endorsee of the Senior Lender or the Lenders of
any of the Senior Debt.

     15.  Governing Law.  This Agreement shall be governed by, and construed in
          --------------
accordance with, the laws of the State of Texas and is performable in Dallas
County, Texas.

     16.  Counterparts.  This Agreement may be executed in counterparts, each of
          ------------
which shall be deemed to be an original for all purposes.

     17.  Defined Terms.  Unless otherwise defined herein, terms used herein are
          -------------
used as defined in the Senior Loan Agreement.

     18.  THIS INTERCREDITOR AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN
THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

<PAGE>

                                  "ARTICLE XII


                                 SUBORDINATION

     SECTION 12.1.  Subordination of Payment.  The payment of the Debt
                    ------------------------
represented by the Notes is hereby expressly subordinated in right of payment to
the prior payment in full of the Senior Debt; provided, however, so long as no
                                              --------  -------
Event of Default has occurred and is continuing for which (other than an event
specified in Subsections 14(f) or (g) of the Senior Credit Agreement as in
effect on November 23, 1999, or any similar provision in any amended, restated
or replaced Senior Credit Agreement) the Company or the Agent under the Senior
Credit Agreement has (or all Senior Lenders thereunder have) given written
notice of such Event of Default to the Noteholders (a "Default Notice"), the
Company may pay only interest due on the Notes according to their terms.  At any
time following the occurrence and during the continuance of any Event of Default
and provided that the Agent under the Senior Credit Agreement has (or all Senior
Lenders thereunder have) given a Default Notice to the Noteholders, the
Noteholders will not accept or receive, any payments in cash, on or with respect
to the Notes unless and until (a) such Event of Default shall have been cured or
waived or shall have ceased to exist or (b) such time as all Senior Debt shall
have been fully paid and performed and the obligation of the Senior Lenders to
make loans under the Senior Credit Agreement shall have terminated.
Notwithstanding the above, if within 180 days after the giving of such Default
Notice by the Company or the Agent under the Senior Credit Agreement (or all
Senior Lenders thereunder) such Event of Default has not become the subject of
an acceleration notice by the Senior Lenders, then the Company may, at its
option (unless in such interval the provision of this Section 12.1 have again
                                                      ------------
come into effect on account of any other Event of Default that did not exist on
the date of any prior Default Notice), resume making any and all required
payments in respect of the Notes in any manner authorized under the terms
governing the Notes until such time (if any) that , such an acceleration notice
is given or a Default Notice is given and a period of 180 days shall not have
elapsed since the giving of such Default Notice as contemplated above.  (If more
than one Default Notice is given, e.g. by the Company and the Agent, such period
                                  ----
shall run from the giving of the first Default Notice.)  In the event any direct
or indirect payment or distribution in cash, shall be received by the
Noteholders in contravention of the provisions hereof, such payment or
distribution shall be held in trust for, and shall be immediately paid over or
delivered to, the Agent under the Senior Credit Agreement.

     SECTION 12.2.  Notes Subordinated to Prior Payment of Senior Debt on
                    -----------------------------------------------------
Dissolution, Liquidation or Reorganization of the Company.  Upon any
- ---------------------------------------------------------
distribution of assets of the Company upon any voluntary or involuntary
dissolution, winding up, liquidation or reorganization of the Company (whether
in bankruptcy, insolvency or receivership proceedings or upon an assignment for
the benefit of creditors or otherwise):


                                       3
<PAGE>

          (a) the Senior Lenders shall first be entitled to receive payment in
     full in cash (or to have such payment duly provided for to their
     satisfaction) of the principal thereof and interest due on the Senior Debt
     and other amounts due in connection therewith before the Noteholders are
     entitled to receive any payment on account of the Notes;

          (b) any payment or distribution of assets of the Company of any kind
     or character, whether in cash, property or securities, to which the
     Noteholders would be entitled except for the provisions of this Article
                                                                     -------
     XII, shall be paid by the liquidating trustee or agent or other person
     ---
     making such payment or distribution directly to the Senior Lenders or their
     representative, to the extent necessary to make payment in full of all
     Senior Debt remaining unpaid, after giving effect to any concurrent payment
     or distribution or provision therefor to the Senior Lenders; and

          (c) in the event that, notwithstanding the foregoing, any payment or
     distribution of assets of the Company of any kind or character, whether in
     cash, property or securities, shall be received by the Noteholders on
     account of principal of or interest on the Notes before the Senior Debt is
     paid in full or provision made for its payment, such payment or
     distribution (subject to the further provisions of this Article XII) shall
                                                             -----------
     be paid over to the Senior Lenders or their representative for application
     to the payment of all Senior Debt remaining unpaid or unprovided for until
     all Senior Debt shall have been paid in full, after giving effect to any
     concurrent payment or distribution or provision therefor to the Senior
     Lenders.

     Notwithstanding the forgoing, the Noteholders may retain stock or
obligations which are issued pursuant to reorganization proceedings in respect
of the Notes (such stock or obligations being "Reorganization Securities") if
such Reorganization Securities are subordinate and junior (whether by law or
agreement) at least to the extent provided in this Article XII to the payment of
all Senior Debt and to the payment of any stock or obligations which are issued
in exchange or substitution for any Senior Debt.  The Noteholders may retain any
cash proceeds of the Reorganization Securities subject to compliance with the
subordination provisions thereof.

     SECTION 12.3.  Subordination of Liens.  So long as the Senior Debt remains
                    ----------------------
outstanding or any obligation of the Senior Lenders exists to make loans under
the Senior Credit Agreement, the Noteholders hereby subordinate all Liens, now
existing or hereafter created or arising, securing all or any portion of the
Notes to all Liens, now existing or hereafter created or arising, securing all
or any portion of the Senior Debt, notwithstanding any defect, deficiency, error
or omission which may be contained in any document creating or perfecting any
such Lien securing all or any portion of the Senior Debt.  All Liens, now
existing or hereafter created or


                                       4
<PAGE>

arising, securing all or any portion of the Notes shall at all times remain
subordinate, secondary and inferior to all Liens, now existing or hereafter
created or arising, securing all or any portion of the Senior Debt.

     SECTION 12.4.  Subordination of Remedies.  So long as the Senior Debt
                    -------------------------
remains outstanding or any obligation of the Senior Lenders exists to make loans
under the Senior Credit Agreement, the Noteholders shall not, without the prior
written consent of the Senior Lenders, declare the Notes due or in default
(other than to accelerate the Notes after the maturity of the Senior Debt,
whether by acceleration or otherwise, and take such other actions as reasonably
required to protect the Noteholders's claims upon any bankruptcy, insolvency, or
receivership proceeding with respect to the Company) or foreclose upon or
exercise any power of sale with respect to any security for all or any portion
of the Notes or exercise any other right, power or remedy of the Noteholders
provided for in any document or instrument executed in connection with the Notes
or by law or initiate or join with any other creditor of the Company in
initiating any plan or proceeding pursuant to any bankruptcy, insolvency or
receivership proceedings or seeking an assignment for the benefit of creditors
or the marshalling of the assets and liabilities of the Company.  Upon any
distribution of assets of the Company or the dissolution, winding up,
liquidation or reorganization (whether in bankruptcy, insolvency or receivership
proceedings or upon an assignment for the benefit of creditors or the
marshalling of the assets and liabilities of the Company or otherwise), any
payment to which the Noteholders would otherwise be entitled with respect to the
Notes shall be held in trust for, and shall be immediately paid over or
delivered to, the Senior Lenders for application to the Senior Debt until all
Senior Debt shall have been paid in full in cash.  Notwithstanding any provision
of this Article XII, (i) the Noteholders may receive payments of interest on the
        -----------
Notes in kind through the Company's election to accrue and add such interest
payment to the principal of the Notes pursuant to the provisions of the Notes;
(ii) the Noteholders may convert the Notes to shares of common stock of the
Company at any time in accordance with the terms of the Notes; (iii) the
Noteholders may exercise any warrants for shares of common stock of the Company
in accordance with the terms of any such warrants and (iv) the Senior Lenders
shall have no rights to the shares of Common Stock obtained by the Noteholders
through conversion of the Notes and exercise of the Warrants.

     SECTION 12.5. Continuing Agreement.  This Agreement shall continue in full
                   --------------------
force and effect and the liabilities and obligations of the Company and the
Noteholders hereunder shall not be affected or impaired by any amendment,
modification or alteration of any Loan Document, except as may be expressly
provided in any such amendment, modification or alteration.  This Agreement
shall continue to be effective or shall be reinstated, as the case may be, if at
any time any payment of any of the Senior Debt is rescinded or must otherwise be
returned by the Senior Lenders upon the insolvency, bankruptcy or reorganization
of the Company or otherwise, all as though such payment had not been made.

     SECTION 12.6. Liability Not Impaired.  The provisions of this  Article XII
                   ----------------------                           -----------
shall

                                       5
<PAGE>

be deemed a continuing offer to all holders of Senior Debt to act in reliance on
such provisions (but no such reliance shall be required to be proven to receive
the benefits hereof) and may be enforced by such holders and no right of any
present or future holder of any Senior Debt to enforce subordination as provided
in this Article XII shall be affected or impaired by (a) the failure of the
        -----------
Agent under the Senior Credit Agreement or the Senior Lenders or any other
Person to exercise diligence or reasonable care in the preservation, protection
or other handling or treatment of all or any part of any Collateral for all or
any portion of the Senior Debt, (b) the failure of any Lien intended to be
granted or created to secure all or any part of the Senior Debt to be properly
perfected or created or the unenforceability of any such Lien for any other
reason, or (c) the subordination of any such Lien to any other Lien.  The Senior
Lenders may at any time and from time to time, without the consent of or notice
to the Noteholders, and without incurring any responsibility to the Noteholders,
and without impairing or releasing or otherwise affecting any of the obligations
or agreements of the Noteholders hereunder, (a) change the manner, place or
terms of payment, or change or extend the time of payment of, renew, or alter
all or any portion of the Senior Debt, (b) exchange, release, surrender, realize
upon or otherwise deal with, in any manner and any order, any Property at any
time subject to any Lien in favor of the Senior Lenders, (c) exercise or refrain
from exercising any rights against the Company or others, and (d) sell,
transfer, assign or grant participations in the Senior Debt or any portion
thereof.

     SECTION 12.7. Waivers.  The Noteholders waive any right to require the
                   -------
Senior Lenders to (a) proceed against the Company or make any effort at the
collection of the Senior Debt from the Company or any other Person liable for
all or any portion of the Senior Debt, (b) proceed against or exhaust any
Collateral securing all or any portion of the Senior Debt, or (c) pursue any
other remedy in the power of the Senior Lenders.

     SECTION 12.8. Knowledge of the Noteholders.  The Noteholders shall not at
                   ----------------------------
any time be charged with knowledge of the existence of any facts which would
prohibit the making of any payment to the Noteholders under the Notes or the
taking of any action under the Notes by the Noteholders unless and until the
Noteholders shall have received written notice thereof from the Agent under the

of any of the Company's time, materials or facilities, or (C) in the opinion of
the Board of Directors of the Company, relates or pertains in any way to the
Company's purposes, activities or affairs, or (ii) before the period in which
Employee is employed by the Company, but only to the extent of Employee's rights
thereto during such period.

     7.  Non-Competition and Non-Disclosure; Injunctive Relief.   Employee
acknowledges that the services he is to render in the course of his employment
by the Company are of a special and unusual character with unique value to the
Company.  In view of the value to the Company of the services of Employee during
the course of his employment by the Company, because of the Business
Opportunities, Intellectual Property and "Confidential Information" (as defined
below) to be obtained by or disclosed to Employee, and as a inducement to the
Company to enter into this Agreement and to pay to Employee the compensation
stated herein, Employee covenants and agrees as follows:

     (a) During the period in which Employee is employed by the Company,
Employee shall not directly or indirectly be employed by or render advisory,
consulting or other services in connection with any business enterprise or
person that is engaged in leasing, acquiring, exploring, producing, gathering or
marketing hydrocarbons and related products.  Notwithstanding the foregoing, the
Company acknowledges that Employee serves on the board of directors of the
entities set forth on Exhibit A attached hereto.  Employee acknowledges and
agrees that in the event a conflict of interests arises between the Company and
any of the entities set forth on Exhibit A attached hereto, Employee shall
immediately notify the Board of such conflict and shall take any and all steps
necessary to protect the Company's best interests.

     (b) During the period in which Employee is employed by the Company,
Employee shall not, directly or indirectly, in any capacity (including, without
limitation, as a proprietor, investor, director or officer or in any other
individual or representative capacity), be financially interested in or engage
in any business that is engaged in leasing, acquiring, exploring, producing,
gathering or marketing hydrocarbons and related products (the "E & P Business");
however, it is specifically agreed between the parties that Employee may
continue to be financially interested in and engage in any E & P Business that
is described on Exhibit A attached hereto, provided, that such activities do not
materially detract from the Employee's performance of his responsibilities as
President and Chief Financial Officer, provided, further that, nothing contained
in this paragraph 7(b) shall relieve the Employee of his obligations contained
in paragraph 7(a) above.   In addition, Employee may make investments in
publicly traded companies that engage in the E & P Business, provided such
investments represent less than one percent (1%) of the issued and outstanding
shares of such company.

     (c) During the period in which Employee is employed by the Company, all
investments made by Employee (whether in his own name or in the name of any
family members), which relate to the lease, acquisition, exploration,
production, gathering or marketing

                                       4
<PAGE>

or hydrocarbons and related products shall be made solely through the Company;
and Employee will not (directly or indirectly through any family members), (i)
invest or otherwise participate alongside the Company in any Business
Opportunities, or (ii) invest or otherwise participate in any business or
activity relating to a Business Opportunity, regardless of whether the Company
ultimately participates in such business or activity.

     (d) During the period in which Employee is employed by the Company and
thereafter, Employee will not disclose to any third party or directly or
indirectly make use of, in a way materially detrimental to the Company, any and
all trade secrets and confidential or proprietary information pertaining to the
Company (collectively referred to as "Confidential Information").  For purposes
of this Section 7, it is agreed that Confidential Information includes, without
limitation, any information heretofore or hereafter acquired, developed or used
by the Company relating to Business Opportunities or Intellectual Property or
other geological, geophysical, economic, financial or management aspects of the
business, operations, properties or prospects of the Company whether oral or in
written form in a "Business Records" (as defined in paragraph 7(g) below).
Notwithstanding the foregoing, no information of the Company will be deemed
confidential for the purposes of this paragraph 7(d) if such information is or
becomes public knowledge through no act of Employee or was previously known by
Employee prior to entering into this Agreement.

     (e) During the Employment Period or the period in which Employee is
employed by the Company, whichever is longer, and for a six-month period
commencing upon the termination of such longer period, Employee may not solicit,
raid, entice or induce, directly or indirectly, any employee (or person who
within the preceding ninety (90) days was an employee) of the Company or any
other person who is under contract with or rendering services to the Company, to
(i) terminate his employment by, or contractual relationship with, the Company,
(ii) refrain from extending or renewing the same (upon the same or new terms),
(iii) refrain from rendering services to or for the Company, or (iv) become
employed by or to enter into contractual relations with any persons other than
the Company.

     (f) Employee acknowledges and agrees that the services to be rendered by
him are of a special, unique and extraordinary character and, in connection with
such services, he will have access to Business Opportunities, Intellectual
Property and Confidential Information vital to the Company's businesses.  By
reason of this, the Employee consents and agrees that if he violates any of the
provisions of this Section 7, the Company would sustain irreparable harm and,
therefore, in addition to any other remedies which the Company may have under
this Agreement or otherwise, the Company shall be entitled to an injunction
restraining the Employee from committing or continuing any such violation of
this Agreement.  Such right to an injunction shall be cumulative and in addition
to, and not in lieu of, any other remedies to which the Company may show itself
justly entitled.  Further, during any period in which the Employee is in breach
of the covenants set forth in this Section 7, the time period of this covenant
shall be extended for an amount of time that the Employee is in breach.

                                       5
<PAGE>

     (g) The Employee agrees to promptly deliver to the Company, upon
termination of Employee's employment with the Company, or at any other time when
the Company so requests, all documents relating to the business of the Company,
including, without limitation: all geological and geophysical reports and
related data such as maps, charts, logs, seismographs, seismic records and other
reports and related data, calculations, summaries, memoranda and opinions
relating to the foregoing, production records, electric logs, core data,
pressure data, lease files, well files and records, land files, abstracts, title
opinions, title or curative matters, contract files, notes, records, drawings,
manuals, correspondence, financial and accounting information, customer lists,
statistical data and compilations, patents, copyrights, trademarks, trade names,
inventions, formulae, methods, processes, agreements, contracts, manuals or any
other documents relating to the business of the Company (collectively, the
"Business Records"), and all copies thereof and therefrom.  The Employee
confirms that all of the Business Records (and all copies thereof and therefrom)
that are required to be delivered to the Company pursuant to this paragraph 7(g)
constitute the exclusive property of the Company.  The obligation of
confidentiality set forth in this Section 7 shall continue notwithstanding the
Employee's delivery of any such documents to the Company.  Notwithstanding the
foregoing provisions of this Section 7 or any other provision of this Agreement,
the Employee shall be entitled to retain any written materials which, as shown
by the Employee's records, were in Employee's possession on or prior to the date
hereof, subject to the Company's right to receive a copy of all such materials.

     (h) The representations and covenants contained in this Section 7 on the
part of the Employee will be construed as ancillary to and independent of any
other provision of this Agreement, and the existence of any claim or cause of
action of the Employee against the Company or any officer, director, or
shareholder of the Company, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by the Company of the
covenants of the Employee contained in this Section 7.  In addition, the
provisions of this Section 7 shall continue to be binding upon the Employee in
accordance with their terms, notwithstanding the termination of the Employee's
employment hereunder for any reason.

     (i) The parties to this Agreement agree that the limitations contained in
this Section 7 with respect to time, geographical area, and scope of activity
are reasonable.  However, if any court shall determine that the time,
geographical area, or scope of activity of any restriction contained in this
Section 7 is unenforceable, it is the intention of the parties that such
restrictive covenants set forth herein shall not thereby be terminated but shall
be deemed amended to the extent required to render it valid and enforceable.

     8.  Termination of Employment

     (a) Death.  Employee's employment shall terminate automatically upon
Employee's death.

                                       6
<PAGE>

     (b) Termination of Employment By the Company For Cause.  The Company may
terminate Employee's employment under this Agreement for Cause.  For purposes
hereof, the term "Cause" shall mean (i) the inability of Employee, despite any
reasonable accommodation required by law, due to bodily injury or disease or any
other physical or mental incapacity, to perform the services provided for
hereunder for a period of 120 days in the aggregate, within any given period of
180 consecutive days during the term of this Agreement, in addition to any
statutorily required leave of absence, (ii) conduct of the Employee that
constitutes fraud, theft, or a criminal act involving moral turpitude, in each
case only if it materially affects his ability to perform the duties and
responsibilities of his position or has a material adverse effect on the
Company, (iii) commission of a material act of fraud against the Company, (iv)
embezzlement of funds or misappropriation of other property by the Employee from
the Company; (v) failure of Employee to observe or perform his material duties
and obligations as an employee of the Company or a material breach of this
Agreement, after thirty (30) days advance written notice of such failure or
breach which has not been cured; (vi) Employee's habitual use of illegal
controlled substances, or intoxication during normal business hours while
conducting the Company's business, which, in the reasonable judgment of the
Board, so impairs  Employee's credibility and reputation that Employee can no
longer perform his duties; or (vii) Employee has been found civilly liable for
sexual harassment or related offenses (or the Company has been found civilly
liable for such actions by Employee).

     (c) Termination By the Company Without Cause.  The Company may also
terminate Employee's employment under this Agreement without Cause.

     (d) Termination By Employee for Good Reason.  If a Change of Control (as
defined hereafter) in the Company has occurred, Employee may terminate his
employment during the Employment Period for Good Reason (defined hereafter) upon
thirty (30) days' notice to the Company.  For purposes of this Agreement, the
term "Good Reason" shall mean the occurrence, without Employee's express written
consent, of any one or more of the following events:

          (i) A material change in Employee's duties (without the consent of
     Employee) or a change in the title or offices held by Employee, or any
     occurrence which causes Employee to have his principal place of employment
     somewhere other than Houston, Texas.

          (ii) A reduction in Employee's compensation or the failure by the
     Company to continue to provide prompt payment (or reimbursement to
     Employee) of all reasonable expenses incurred by Employee in connection
     with Employee's professional and business activities.

                                       7
<PAGE>

          (iii)  A failure by the Company to waive any and all restrictions that
     might exist on the exercise of any stock options held by Employee under the
     Company's stock option plans as of the date of a Change of Control.

          (iv) The failure of the Company to obtain the assumption of this
     Agreement, without limitation or reduction, by any successor to the
     Company.

     (e) Change of Control.  A "Change of Control" shall have occurred if:

          (i) fifty percent (50%) or more of the outstanding common stock of the
     Company has been acquired by any person or persons (as defined in Section
     3(a)(9) of the Securities Exchange Act of 1934 (the "Act")), provided such
     person(s) is not a  stockholder(s) of the Company currently holding ten
     percent (10%) or more of the outstanding common stock of the Company at the
     time of the execution of this Agreement.  For purposes of this paragraph 8,
     such person shall include affiliated persons (as defined in the Act));

          (ii) there has been a merger or equivalent combination involving the
     Company after which fifty percent (50%) or more of the voting stock of the
     surviving corporation is held by persons other than those persons who were
     stockholders holding ten percent (10%) or more of the outstanding stock of
     the Company immediately prior to the date of such merger or equivalent
     combination; or

          (iii)  there has been a merger or equivalent combination or stock sale
     involving the Company and after such transaction fifty percent (50%) or
     more of the members of the surviving company's Board of Directors elected
     by stockholders are persons who were not directors immediately prior to
     such transaction; or

     (f) Voluntary Termination By Employee.  Employee shall have the right at
any time after the date hereof to voluntarily terminate his employment with the
Company (a "Voluntary Termination") for any reason in the sole discretion of
Employee by not less than thirty (30) days' prior written notice to the Company;
provided however, a termination without Cause or a termination for Good Reason
shall not be treated for any purpose hereunder as a Voluntary Termination.

     9.  Termination Procedures and Certain Definitions.

     (a) Notice of Termination.  Any termination by the Company for Cause,
without Cause or by Employee for Good Reason or in a Voluntary Termination,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with paragraph 13 of this Agreement.  For purposes of this
Agreement, a "Notice of Termination" means a written notice which (i) indicates
the specific termination provision in this Agreement relied upon, (ii) to the

                                       8
<PAGE>

extent applicable, sets forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of Employee's employment under the
provision so indicated and (iii) if the Date of Termination (as defined below)
is other than the date of receipt of such notice, specifies the termination
date.  The failure by Employee or the Company to set forth in the Notice of
Termination any fact or circumstance which contributes to a showing of Good
Reason or Cause shall not waive any right of Employee or the Company,
respectively, hereunder or preclude Employee or the Company, respectively, from
asserting such fact or circumstance in enforcing Employee's or the Company's
rights hereunder.  Employee's continued employment with the Company, after a
Notice of Termination is provided, shall not constitute consent to, or a waiver
of any rights with respect to, any circumstance constituting Good Reason
hereunder.

     (b) Date of Termination.  "Date of Termination" means (i) if Employee's
employment is terminated by the Company for Cause, the date of Employee's
receipt of the Notice of Termination or any later date specified therein, as the
case may be, (ii) if Employee's employment is terminated by the Company other
than for Cause, the Date of Termination shall be the date not less than thirty
(30) days after the date on which the Company notifies Employee of such
termination, and (iii) if Employee terminates his employment for Good Reason or
in a Voluntary Termination, the Date of Termination shall be the date, not less
than thirty (30) days after the date on which Employee notifies the Company of
such termination.

     10.  Obligations of the Company on Termination.

     (a) If during the Employment Period, Employee's employment is terminated
with Cause, upon Employee's death or upon a Voluntary Termination, the Company
shall immediately pay Employee in cash the portion of his Base Compensation
previously earned but not yet paid.

     (b) If during the Employment Period, Employee's employment is terminated by
the Company without Cause or by Employee for Good Reason:

          (i) In General.  The Company shall immediately pay Employee in cash
     the amount of his Total Compensation previously earned but not yet paid.

          (ii)  Severance Benefits.

                    (a) All stock options granted to Employee under the
               Company's stock option plans, which have not already vested,
               shall immediately vest and be exercisable.

                    (b) Employee shall continue to participate in all of the
               Company's welfare benefit plans, including health and medical
               plans, for six (6) months after termination and shall be entitled
               to reimbursement of

                                       9
<PAGE>

               COBRA payments to maintain medical and dental insurance up to
               twelve (12) additional months for said coverage.

                    (c) The Company shall pay Employee in a lump sum a
               "Severance Benefit" in cash equal to two (2) times Employee's
               Base Compensation as of the date of such termination.

          Such payment shall be made within thirty (30) days following said
     termination.

     11.  Burden and Benefit.   This Agreement shall be binding upon, and shall
inure to the benefit of, the Company and Employee, and their respective heirs,
personal and legal representatives, successors and permitted assigns.
Employee's rights and obligations may not be assigned without the proper written
consent of the Company.

     12.  Governing Law.  It is understood and agreed that the construction and
interpretation of this Agreement shall at all times and in all respects be
governed by the laws of the State of Texas.  The parties hereto hereby

     in subsection (b) below, but unadjusted by any other adjustments provided
     for in this Agreement or agreed to by the parties, being herein called the
     "BASE PURCHASE PRICE").  Such Base Purchase Price may be adjusted as

<PAGE>

     Price, as so adjusted, and as the same may otherwise be adjusted by mutual
     agreement of the parties, being herein called the "PURCHASE PRICE"). Except
     as may be provided in Sections 11(a)(ii) and 11(b)(ii) with respect to
     payment of the Operations Adjustment portion of the Base Purchase Price

     Gas Properties include royalties and overriding royalties which were not
     considered by Buyer in establishing the $55,000,000 amount set forth above.
     The parties, therefore, agree that such amount will be adjusted upward as
     follows:  (i) for each well or PUD location listed on Schedule I that shows
     a "RI" or "ORRI" decimal net revenue interest on such schedule, the total
     of such "RI" and "ORRI" interests will be divided by the average of the
     decimal net revenue interest shown for "BPO NRI" and "APO NRI" for such
     well or PUD location on such Schedule (or the "APO NRI" where no "BPO NRI"
     is shown) and multiplying such result by the allocated value shown for such
     well or PUD location on Schedule I and (ii) adding the total of the amounts
     computed under clause (i) to such $55,000,000 amount as set forth above.

     3. DEPOSIT.  Contemporaneously with the execution of this Agreement, Buyer,
Seller and Bank One Texas, N.A. ("ESCROW AGENT") shall execute an escrow
agreement in the form of Exhibit B attached hereto (the "ESCROW AGREEMENT").
Pursuant to the terms of the Escrow Agreement, Buyer shall deliver to the Escrow
Agent Five Million Two Hundred Thousand Dollars ($5,200,000) (such amount, plus
any interest earned thereon, being herein called the "DEPOSIT"). The costs
associated with such escrow shall be split equally between Buyer and Seller.  In
the event the transaction contemplated hereby is consummated in accordance with
the terms hereof, the Deposit shall be applied to the Purchase Price to be paid
by Buyer at the Closing.  In the event the transaction contemplated hereby fails
to close on the Closing Date as a result of a material breach of this Agreement
by Seller which occurs in the absence of a material breach of this Agreement by
Buyer, or in the event this Agreement is terminated by Buyer in accordance with
Section 9 below or is terminated by Seller in accordance with any subsection of
Section 10 below other than subsections 10(a) and 10(b), the Deposit shall be
returned to Buyer.  If the transaction contemplated hereby otherwise fails to
close on the Closing Date, Seller shall retain the Deposit.  THE PARTIES HEREBY
ACKNOWLEDGE THAT THE EXTENT OF DAMAGES TO SELLER OCCASIONED BY THE FAILURE OF
THIS TRANSACTION TO BE CONSUMMATED WOULD BE IMPOSSIBLE OR EXTREMELY DIFFICULT TO
ASCERTAIN AND THAT THE AMOUNT OF THE DEPOSIT IS A FAIR AND REASONABLE ESTIMATE
OF SUCH DAMAGES UNDER THE CIRCUMSTANCES AND DOES NOT CONSTITUTE A PENALTY AND
SHALL BE SELLER'S SOLE AND EXCLUSIVE REMEDY.

     4. REPRESENTATIONS OF SELLER.

        (a) REPRESENTATIONS.   Each Seller represents and warrants to Buyer
     that:

        (i) ORGANIZATION AND QUALIFICATION.  Each of C.W. Resources, Inc. and
     Westerman Royalty, Inc., is a corporation duly organized and legally
     existing and in good standing under the laws of the State of Texas.

        (ii) DUE AUTHORIZATION.  Each Seller has full power to enter into and
     perform its obligations under this Agreement and has taken all proper
     action to authorize entering into this Agreement and performance of its
     obligations hereunder.

        (iii)  APPROVALS.  Other than requirements (if any) that there be
     obtained consents to assignment from third parties (any material contracts
     containing such consent requirements being disclosed under section 4(a)(x)
     below) and except for approvals ("ROUTINE GOVERNMENTAL APPROVALS") required
     to be obtained from governmental entities who are lessors under leases
     forming a part of the Oil and Gas Properties (or who administer such leases
     on behalf of such lessors) which are customarily obtained post-closing, and
     except for the requirements of any maintenance of uniform interest
     provisions contained in any operating or other agreements, to Seller's
     knowledge, neither the execution and delivery of this Agreement, nor the
     consummation of the transactions contemplated hereby, nor the compliance
     with the terms hereof, will result in any default under any agreement or
     instrument to which Seller is a party or by which the Properties are bound,
     or violate any order, writ, injunction, decree, statute, rule or regulation
     applicable to Seller or to the Properties.  Seller's "knowledge," or
     "received" by Seller (except as used in connection with payment receipts),
     as used in this Agreement, shall mean to the actual knowledge of, or
     actually received by, Carl A. Westerman, Paul A. Kopasko, Dawn W. Tadlock,
     David Tadlock, Bruce Cook or Michelle Cook.

        (iv) VALID, BINDING AND ENFORCEABLE.  This Agreement constitutes (and
     the Conveyance provided for herein to be delivered at Closing will, when
     executed and delivered, constitute) the legal, valid and binding obligation
     of Seller, enforceable in accordance with its terms, except as limited by
     bankruptcy or other laws applicable generally to creditor's rights and as
     limited by general equitable principles.

        (v) LITIGATION.  Except as disclosed on the Disclosure Schedule (herein
     called the "DISCLOSURE SCHEDULE") attached hereto as Schedule II, there are
     no pending suits, actions, or other proceedings in which Seller is a party
     (or to Seller's knowledge, which have been threatened to be instituted)
     which affect the Properties (including, without limitation, any actions
     challenging or pertaining to Seller's title to any of the Properties), or
     affect the execution and delivery of this Agreement or the consummation of
     the transactions contemplated hereby.

        (vi) TITLE.  Seller is the owner of the Oil and Gas Properties, free and
     clear of

                                       4
<PAGE>

     all liens, burdens, encumbrances and defects in title arising by, through
     or under Seller. It is expressly understood and agreed that such
     representation does not cover matters arising other than by, through or
     under Seller, and it is further expressly understood and agreed that,
     without limitation, matters arising by, through or under Seller do not
     include maintenance of leases in force or pooling and/or unitization
     matters.

        (vii)  ENVIRONMENTAL.  Except as disclosed on the Disclosure Schedule,
     to Seller's knowledge, there are no pending or threatened actions, suits,
     orders, claims, notices or proceedings, made or instituted by applicable
     governmental authorities, regarding the Properties alleging a violation or
     non-compliance with applicable environmental laws, or with respect to the
     disposal, discharge or release from the Properties of hazardous materials
     or constituents in a manner which is not in compliance with such laws.

        (viii)   GAS IMBALANCES AND PREPAYMENT.  Seller is not obligated, by
     virtue of any prepayment arrangement, a "take or pay" arrangement, gas
     balancing agreement, a production payment or any other arrangement entered
     into by it (or, to Seller's knowledge, entered into by any other party and
     binding on the Oil and Gas Properties), to deliver hydrocarbons produced
     from the Oil and Gas Properties at some future time without then or
     thereafter receiving full payment therefor.

        (ix) PROCEEDS IN SUSPENSE.  Proceeds from the sale of hydrocarbons
     produced from the Oil and Gas Properties are being received by Seller in a
     timely manner and are not being held in suspense by the purchaser of said
     hydrocarbons for any reason, other than amounts held in suspense by such
     purchaser in the ordinary course of business which are individually or in
     the aggregate not in excess of $100,000.

        (x) MATERIAL CONTRACTS; PREFERENTIAL RIGHTS.  The Disclosure Schedule
     sets forth a complete and accurate description of every material agreement
     entered into by Seller (or, to Seller's knowledge, entered into by any
     other party and binding on the Oil and Gas Properties), and relating to the
     Oil and Gas Properties, and no written claim has been received by Seller
     that it is in default under any such agreement. No hydrocarbons produced
     from the Oil and Gas Properties are subject to a sales contract or other
     arrangement entered into by Seller and relating to the production,
     gathering, transporting, processing, treating or marketing of hydrocarbons
     (other than a contract disclosed on the Disclosure Schedule), and, except
     as included in agreements set forth on the Disclosure Schedule, no person
     has any preferential right to purchase any Oil and Gas Property and no
     person has any call upon, option to purchase, preferential right to
     purchase or similar rights granted by Seller with respect to production
     from the Oil and Gas Properties and none of the persons so listed on the
     Disclosure Schedule have exercised any such rights.

                                       5
<PAGE>

        (xi) RECEIPT OF PROCEEDS; PAYMENT OF EXPENSES.  With respect to each
     existing well identified on Schedule I, Seller is currently receiving from
     all purchasers of production from the Oil and Gas Properties at least the
     "Net Revenue Interests" set forth on such Schedule I without suspense.
     With respect to each existing well listed on Schedule I, Seller is
     currently paying the operators of the Oil and Gas Properties for the
     development and operation thereof no more than the Operating Interests set
     forth on such Schedule I, and Seller is current for all costs and expenses
     pertaining to the development and operation of the Oil and Gas Properties,
     except for those being contested in good faith.

        (xii)  PAYMENT OF ROYALTIES.  Except for the Jane Turner Sheppard et al
     vs. C.W. Resources et al. case disclosed on the Disclosure Schedule, Seller
     has received no claims that royalties and other payments due by it under
     the leases have not been properly and timely paid, or that any conditions
     necessary to keep the leases in force have not been fully performed.

        (xiii)  COMPLIANCE WITH LAWS.  Seller has received no claims, orders,
     notices or other written communications from applicable governmental
     authorities that the operation of the Oil and Gas Properties has not been
     conducted in accordance with all laws, rules, regulations, ordinances and
     orders (including without limitation, those pertaining to the environment)
     of all local, state and federal governmental bodies, authorities and
     agencies having jurisdiction of the Oil and Gas Properties.

        (xiv)  TAXES.  Ad valorem, property, production, severance, excise and
     similar taxes and assessments based on or measured by ownership of property
     or the production of hydrocarbons or the receipt of proceeds therefrom on
     the Oil and Gas Properties that have become due and payable have been
     properly and timely paid, except for those being contested in good faith.
     For purposes of this Agreement, taxes based on or measured by production
     shall be deemed attributable to the period in which the production
     occurred, regardless of the fact that such taxes may not be assessed or
     payable until some subsequent period.

        (b) DISCLAIMERS.  THE EXPRESS REPRESENTATIONS AND WARRANTIES OF SELLER
     CONTAINED IN SECTION 4(a) ABOVE ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER
     REPRESENTATIONS AND WARRANTIES, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
     AND, WITHOUT LIMITATION ON THE EXPRESS REPRESENTATIONS AND WARRANTIES
     CONTAINED IN SECTION 4(a) ABOVE, SELLER EXPRESSLY DISCLAIMS ANY AND ALL
     OTHER REPRESENTATIONS AND WARRANTIES (WITHOUT LIMITATION, EXCEPT FOR THE
     EXPRESS REPRESENTATIONS AND WARRANTIES CONTAINED IN SECTION 4(a) ABOVE, THE
     PROPERTIES SHALL BE CONVEYED PURSUANT HERETO WITHOUT ANY WARRANTY OR
     REPRESENTATION WHETHER EXPRESS,

                                       6
<PAGE>

     IMPLIED, STATUTORY OR OTHERWISE, RELATING TO THE CONDITION, QUANTITY,
     QUALITY, FITNESS FOR A PARTICULAR PURPOSE, CONFORMITY TO THE MODELS OR
     SAMPLES OF MATERIALS OR MERCHANTABILITY OF ANY EQUIPMENT FOR ITS FITNESS
     FOR ANY PURPOSE). UPON CLOSING, BUYER SHALL HAVE INSPECTED, OR WAIVED ITS
     RIGHT TO INSPECT, THE PROPERTIES FOR ALL PURPOSES AND SATISFIED ITSELF AS
     TO THEIR PHYSICAL AND ENVIRONMENTAL CONDITION, BOTH SURFACE AND SUBSURFACE,
     INCLUDING BUT NOT LIMITED TO CONDITIONS SPECIFICALLY RELATED TO THE
     PRESENCE, RELEASE OR DISPOSAL OF HAZARDOUS SUBSTANCES, SOLID WASTES,
     ASBESTOS AND OTHER MAN MADE FIBERS, OR NATURALLY OCCURRING RADIOACTIVE
     MATERIALS ("NORM"). BUYER IS RELYING UPON ITS OWN INSPECTION OF THE
     PROPERTIES, AND BUYER SHALL ACCEPT ALL OF THE SAME IN THEIR "AS IS, WHERE
     IS" CONDITION.

     5. REPRESENTATIONS OF BUYER.  Buyer represents to Seller that:

        (a) ORGANIZATION AND QUALIFICATION.  Buyer is a corporation duly
     organized and legally existing and in good standing under the laws of its
     state of incorporation and is qualified to do business and in good standing
     in the State of Texas.  Buyer is also qualified to own and operate oil and
     gas properties with all applicable governmental agencies having
     jurisdiction over the Properties, to the extent such qualification is
     necessary or appropriate or will be necessary or appropriate upon
     consummation of the transactions contemplated hereby (including, without
     limitation, Buyer has met all bonding requirements of such agencies).

        (b) DUE AUTHORIZATION.  Buyer has full power to enter into and perform
     its obligations under this Agreement and has taken all proper action to
     authorize entering into this Agreement and performance of its obligations
     hereunder.

        (c) APPROVALS.  Other than requirements (if any) that there be obtained
     consents to assignment (or waivers of preferential rights to purchase) from
     third parties, and except for Routine Governmental Approvals, neither the
     execution and delivery of this Agreement, nor the consummation of the
     transactions contemplated hereby, nor the compliance with the terms hereof,
     will result in any default under any agreement or instrument to which Buyer
     is a party, or violate any order, writ, injunction, decree, statute, rule
     or regulation applicable to Buyer.

        (d) VALID, BINDING AND ENFORCEABLE.  This Agreement constitutes (and the
     Conveyance provided for herein to be delivered at Closing will, when
     executed and delivered, constitute) the legal, valid and binding obligation
     of Buyer, enforceable in accordance with its terms, except as limited by
     bankruptcy or other laws applicable generally to creditor's rights and as
     limited by general equitable principles.

        (e) NO LITIGATION.  There are no pending suits, actions, or other
     proceedings in

                                       7
<PAGE>

     which Buyer is a party (or, to Buyer's knowledge, which have been
     threatened to be instituted against Buyer) which affect the execution and
     delivery of this Agreement or the consummation of the transactions
     contemplated hereby.

        (f) KNOWLEDGEABLE BUYER, NO DISTRIBUTION.  Buyer is a knowledgeable
     purchaser, owner and operator of oil and gas properties, has the ability to
     evaluate (and in fact has evaluated) the Properties for purchase, and is
     acquiring the Properties for its own account and not with the intent to
     make a distribution in violation of the Securities Act of 1933 as amended
     (and the rules and regulations pertaining thereto) or in violation of any
     other applicable securities laws, rules or regulations.

     6. CERTAIN COVENANTS OF SELLER PENDING CLOSING.  Between the date of this
Agreement and the Closing Date:

        (a)  ACCESS BY BUYER.

        (i) RECORDS.  Seller will give Buyer, or Buyer's authorized
     representatives, at Seller's office and at all reasonable times before the
     Closing Date, access to Seller's records pertaining to the ownership and/or
     operation of the Properties (including, without limitation, title files,
     division order files, well files, and production, severance and ad valorem
     tax records), for the purpose of conducting due diligence reviews
     contemplated by Section 7 below.  Buyer may make copies of such records, at
     its expense, but shall, if Seller so requests, return all copies so made if
     the Closing does not occur; all costs of copying such items shall be borne
     by Buyer.  Seller shall not be obligated to provide Buyer with access to
     any records or data which Seller believes that Seller cannot provide to
     Buyer without, in Seller's reasonable opinion, breaching, or risking a
     breach of, agreements with other parties, or waiving, or risking waiving,
     legal privilege.  Notwithstanding the foregoing sentence, Seller shall
     provide Buyer a list of all records or data which Seller is withholding
     pursuant to such sentence including a general description of such records'
     contents and the specific reason claimed by Seller for such withholding.

        (ii) PHYSICAL INSPECTION.  Seller shall make a good faith effort to give
     Buyer, or Buyer's authorized representatives, at all reasonable times
     before the Closing Date and upon adequate notice to Seller, physical access
     to the Properties for the purpose of inspecting same.  Buyer recognizes
     that some or all of the Properties may be operated by parties other than
     Seller and that Seller's ability to obtain access to such properties, and
     the manner and extent of such access, is subject to such third parties.
     Buyer agrees to comply fully with the rules, regulations and instructions
     issued by Seller (and, where Properties are operated by other parties, such
     other parties) regarding the actions of Buyer while upon, entering or
     leaving the Properties.

                                       8
<PAGE>

        (iii)  EXCULPATION AND INDEMNIFICATION.  If Buyer exercises rights of
     access under this Section or otherwise, or conducts examinations or
     inspections under this Section or otherwise, then (a) such access,
     examination and inspection shall be at Buyer's sole risk, cost and expense
     and Buyer waives and releases all claims against Seller (and the respective
     affiliates of the parties constituting Seller and the respective directors,
     officers, employees, attorneys, contractors and agents of such parties and
     such affiliates) arising in any way therefrom or in any way connected
     therewith or arising in connection with the conduct of its directors,
     officers, employees, attorneys, contractors and agents in connection
     therewith and (b) Buyer shall indemnify, defend and hold harmless Seller
     (and the respective affiliates of the parties constituting Seller and the
     respective officers, directors, employees, attorneys, contractors and
     agents of such parties and such affiliates)from any and all claims,
     actions, causes of action liabilities, damages, losses, costs or expenses
     (including, without limitation, court costs and attorneys' fees), or liens
     or encumbrances for labor or materials, arising out of or in any way
     connected with Buyer's examinations or inspections.

        (b) INTERIM OPERATION.  Seller will continue the operation of the
     Properties in the ordinary course of its business (or, where Seller is not
     the operator of a Property, will continue its actions as a non-operator in
     the ordinary course of its business), and will not sell or otherwise
     dispose of any of the Properties, provided that Seller may make sales or
     other dispositions of oil, gas and other minerals in the ordinary course of
     business after production (but, in doing so, will not enter into any new
     marketing arrangements unless the same terminate, or can be terminated, (in
     either case without penalty or other detriment) in 31 days or less), and
     may make sales or other dispositions of equipment and other personal
     property or fixtures in the ordinary course of business where the same has
     become obsolete and is no longer necessary for the operation of the
     Properties, or is replaced by an item or items of at least equal
     suitability and value.  Except for those disclosed on the Disclosure
     Schedule (with respect to which Seller may take the actions described on
     the Disclosure Schedule) Seller will not, without Buyer's written consent,
     commit to or propose the drilling of any additional wells, commit to or
     propose the deepening, plugging back or reworking of any existing wells, or
     commit to or propose the conducting of any other operations which require
     consent under the applicable operating agreement.  Except for those
     disclosed on the Disclosure Schedule (with respect to which Seller may take
     the actions described on the Disclosure Schedule) Seller will advise Buyer
     of any such proposals made by other parties, and will consult with Buyer
     concerning such proposals, but any decisions with respect to such proposals
     shall be made by Seller in its own discretion, so long as the decisions are
     made in the ordinary course of business; provided that, if the period for
     responding to such a proposal extends beyond the Closing Date, Seller will
     not respond to such proposal unless the Closing does not occur prior to the
     next to last day allowed to respond (in which case Seller may respond).
     Without expanding any obligations which Seller may have to Buyer, it is
     expressly agreed that Seller shall never have any liability to Buyer with
     respect to

                                       9
<PAGE>

     operation of a Property greater than that which it might have as the
     operator to a non-operator under the applicable operating agreement (or, in
     the absence of such an agreement, under the AAPL 610 (1989 Revision) form
     Operating Agreement), IT BEING RECOGNIZED THAT, UNDER SUCH AGREEMENTS AND
     SUCH FORM, THE OPERATOR IS NOT RESPONSIBLE FOR ITS OWN NEGLIGENCE, AND HAS
     NO RESPONSIBILITY OTHER THAN FOR GROSS NEGLIGENCE OR WILFUL MISCONDUCT.

     7. DUE DILIGENCE REVIEWS.

        (a) REVIEW BY BUYER.  Buyer may conduct, at its sole cost, such title
     examination or investigation, and other examinations and investigations, as
     it may in its sole discretion choose to conduct with respect to the
     Properties in order to determine whether Defects (as below defined) exist.
     Should, as a result of such examinations and investigations, or otherwise,
     one or more matters come to Buyer's attention which would constitute a
     Defect (as below defined), and should there be one or more of such Defects
     which Buyer is unwilling to waive and close the transaction contemplated
     hereby notwithstanding the fact that such Defects exist, Buyer shall notify
     Seller in writing of such Defects as soon as the same are identified by
     Buyer, but in no event no later than May 24, 2000, (such Defects of which
     Buyer so provides notice are herein called "ASSERTED DEFECTS").  Such
     notification shall include, for each Asserted Defect, (i) a description of
     the Asserted Defect and the wells and/or units listed on Schedule I to
     which it relates, (i) the Defect is a Defect described in Section 7(b)(i)
     below, (ii) for each applicable well or unit, the size of any variance from
     "Net Revenue Interest" or "Working Interest" which does or could result
     from such Asserted Defect and (iii) the amount by which Buyer would propose
     to adjust the Purchase Price.   All access to Sellers records and the
     Properties in connection with such due diligence shall be subject and
     pursuant to Section 6(a) (including, without limitation, the exculpation
     and indemnification provisions contained in Section 6(a)(iii)).

        (b) NATURE OF DEFECTS.  The term "DEFECT" as used in this Section shall
     mean the following:

        (i) NRI OR WI VARIANCES.  Seller's ownership of the Properties is such
     that, with respect to a well or PUD location listed on Schedule I hereto,
     it clearly (A) entitles Seller to receive a decimal share of the oil, gas
     and other hydrocarbons produced from currently producing completions in
     such well (or, in the case of a PUD location, from the Cotton Valley Sand
     Formation), which is less than the decimal share set forth on Schedule I in
     connection with such well or PUD location in the column headed "Net Revenue
     Interest" or (B) causes Seller to be obligated to bear a decimal share of
     the cost of operation of such well (as to such completions) or PUD location
     (as to such formation) greater than the decimal share set forth on Schedule
     I in connection with such well or PUD location in the column headed
     "Working Interest" (without at least a proportionate increase in the share
     of

                                       10
<PAGE>

     production to which Seller is entitled to receive from such well or PUD
     location).

        (ii) LIENS.  Seller's ownership of an Oil and Gas Property is subject to
     a lien other than (A) a lien for taxes which are not yet delinquent or (B)
     a mechanic's or materialmen's lien (or other similar lien), or a lien under
     an operating agreement or similar agreement, to the extent the same relates
     to expenses incurred which are not yet delinquent or (C) liens which will
     be released at or before Closing.

        (iii)  PREFERENTIAL RIGHTS AND CONSENTS.  Seller's ownership of an Oil
     and Gas Property is subject to a Preferential Right or a requirement that
     Consent to assignment be obtained, unless a waiver of such Preferential
     Right or Consent has been obtained with respect to the transaction
     contemplated hereby, or (in the case of a Preferential Right) an
     appropriate tender of the applicable interest has been made to all parties
     holding such right and, with respect to each such party, the period of time
     required for such party to exercise such right has expired without such
     party exercising such right.

        (iv) IMPERFECTIONS IN TITLE.  Seller's ownership of an Oil and Gas
     Property is subject to an imperfection in title which, if asserted, would
     cause a Defect, as defined in subparagraph (i) above, to exist, and such
     imperfection in title is not such as would normally be waived by persons
     engaged in the oil and gas business when purchasing producing properties.

        (v) PRODUCTION SALES CONTRACTS.  An Oil and Gas Property is subject to a
     production sales contract (other than a contract disclosed on the
     Disclosure Schedule or a contract which provides market sensitive pricing)
     which does not terminate by its terms on or before 185 days after the
     Closing Date and which cannot be terminated on or before 185 days after the
     Closing Date without penalty.

        (vi) ENVIRONMENTAL MATTERS.  An Oil and Gas Property is in violation of
     (whether or not Seller has been cited for such violation) applicable
     environmental laws (below defined) in any material respect ("applicable
     environmental laws" shall mean all federal, state or local laws, rules,
     orders or regulations pertaining to health or the environment, including
     those relating to waste materials and/or hazardous substances) or there is
     present upon or under such property a condition which requires or with the
     passage of time is likely to require remediation under applicable
     environmental law and such matter is not such as would normally be accepted
     by persons engaged in the oil and gas business when purchasing producing
     properties.

        (vii)  LITIGATION.  A matter which should have been disclosed on the
     Disclosure Schedule pursuant to Section 4(a)(v), but was not so disclosed.

     Notwithstanding anything in the foregoing which may appear to the contrary,
     unleased

                                       11
<PAGE>

     interests or non pooled, or ineffectively pooled, interests in a tract on
     which no well (or a drillsite for a PUD location) included in the
     Properties is located shall not constitute a "Defect." Similarly, in some
     cases where an "APO NRI" net revenue interest is shown for a well or PUD
     location on Schedule I one or more third parties have elections at payout
     (which do not have to be exercised until then) to take one of two or more
     possible interests, and such net revenue interest shown on Schedule I
     assumes one of such interests would be elected; notwithstanding anything in
     the foregoing which appears to the contrary, the fact that a third party
     may make a different election at payout than that assumed in computing the
     net revenue interest shown on Schedule I will not constitute a "Defect."
     The presence of naturally occurring radioactive materials ("NORM") in
     circumstances where, under current Texas Railroad Commission rules and
     regulations, remediation is not currently required will not constitute a
     "Defect."

        (c) PUD LOCATIONS.  Buyer and Seller have identified certain PUD
     locations at which additional wells might be drilled to the Cotton Valley
     Sand Formation, which locations are identified on Exhibit C hereto.  Such
     locations are included on Schedule I hereto (and have amounts allocated to
     them as do existing wells), and are subject to the procedures relating to
     Defects and Asserted Defects set forth above in this Section 7, and to the
     curative and purchase price adjustment procedures set forth below in this
     Section 7 and Section 8.  With respect to such locations, and such
     procedures, Buyer and Seller additionally agree as follows:

        (i) ADJUST LOCATION, SUBSTITUTE PUD.  If an Asserted Defect is
     identified with the tract on which such location is located, Buyer will use
     its best efforts to identify a reasonably acceptable alternative location
     for such PUD, on a tract not so affected, in order to eliminate such
     Defect.  Alternatively, if Seller can identify an additional PUD location
     on the Oil and Gas Properties which is not included in the PUD locations
     shown on Exhibit C, Buyer will review such location (and any supporting
     data furnished by Seller) in a good faith, and, should Buyer determine that
     such location is a reasonably acceptable alternative location, such
     location shall be substituted for the PUD location having the Asserted
     Defect, and such Asserted Defect will be eliminated.

        (ii) MINIMAL DEFECTS, INCOMPLETE POOLING.  Asserted Defects relating to
     a PUD location must affect at least 5% of Leasehold interest of the
     drillsite tract for such PUD for the same to be considered Defects subject
     to price adjustment procedures provided for below.  If Asserted Defects for
     a PUD location affect interests which exceed such amount, the price
     adjustment procedure provided for below will be followed for the interest
     affected in excess of such amount; if the interest affected do not exceed
     such amount, no price adjustment for Asserted Defects will be made.  The
     absence of complete pooling authority for all interests held by Seller in a
     PUD location will not constitute a Defect.

                                       12
<PAGE>

        (iii)  OFFSETS.  Should Seller have an interest in a PUD location that
     is more than 105% of that projected on Schedule I, such excess (with the
     amount attributable to such excess to be determined in the same manner as
     provided below for price adjustments) may be used to offset purchase price
     reductions otherwise applicable to other PUD locations due to Defects
     thereon.

        (iv) CONTINUING CURATIVE.  If an Asserted Defect is identified with
     respect to such a location, and the same cannot be cured before Closing (or
     resolved as provided in (i) above), Seller may elect to continue curative
     efforts past Closing.  In such case, the amount determined, as provided in
     Section 8 below, to be attributable to such Defect will be left in escrow
     under the Escrow Agreement and will be disbursed (A) if such Defect is
     cured within one year after Closing, to Seller when such curative is
     completed (with interest earned on such amount up to Closing being
     disbursed to Buyer, and all other interest earned on such amount being
     disbursed to Seller) or (B) otherwise, to Buyer as promptly as possible
     after such one year period (together with all interest earned on such
     amount).  If the amount to be so left in escrow exceeds $1,000,000, the
     amount so left in escrow may, at Buyer's option, be limited to not less
     than $1,000,000, and any additional amounts will be paid directly by Buyer;
     provided that payments on account of curative by Seller shall be first paid
     from the amount left in escrow (until the amount so left in escrow is
     depleted), and then paid by Buyer; and provided further that any such
     amounts to be paid directly by Buyer shall be (A) when and if curative is
     done with respect to Asserted Defects, paid to Seller in the same manner as
     provided for escrow funds above (but without interest), or (B) to the
     extent curative does not occur within such period, retained by Buyer.

        (d) SELLER'S RESPONSE.  In the event that Buyer notifies Seller of
     Asserted Defects:

        (i) CURE.  Seller may (but shall have no obligation to) attempt to cure,
     prior to Closing, one or more Asserted Defects.

        (ii) POSTPONE CLOSING.  Whether or not Seller has then begun to, or ever
     begins to, cure one or more Asserted Defects (and whether or not Seller has
     elected options (iii) or (iv) below with respect to one or more Asserted
     Defects), Seller may postpone the Closing by designating a new Closing Date
     not later than June 15, 2000.  Notwithstanding any such election to
     postpone Closing, Seller shall still have no obligation to cure Asserted
     Defects.

        (iii)  INDEMNIFICATION.  At any time, and from time to time, prior to
     Closing, and regardless of whether or not Seller has then elected any other
     option or options under this Section as to such Asserted Defect or any
     other Asserted Defect (including without limitation regardless of whether
     the procedure under Section 8 is ongoing as to such Asserted Defect),
     Seller may (but shall have no obligation to) elect, with respect to any
     Asserted Defect, to indemnify and hold Buyer harmless

                                       13
<PAGE>

     from and against any actual damages or loss (but specifically excluding
     consequential, special or similar damages) Buyer may suffer as a result of
     a third party claim based on such Asserted Defect. If and when such
     election is made as to an Asserted Defect, such Asserted Defect will be
     treated under this Agreement as if cured.

        (iv) ADJUSTMENT.  Notwithstanding any other election made under this
     Section (without limitation, it being expressly recognized that Seller may
     attempt to cure Asserted Defects while acting under this election), Seller
     may elect to have one or more Asserted Defects handled under Section 8
     below.

     8. CERTAIN PRICE ADJUSTMENTS.

        (a) PROCEDURES.  In the event that, as a part of the due diligence
     reviews provided for in Section 7 above, Asserted Defects are presented to
     Seller and Seller is unable (or unwilling) to cure such Asserted Defects
     prior to Closing, or in the event that Buyer or Seller has elected
     (pursuant to Section 15) to treat an Oil and Gas Property affected by a
     casualty loss as if it was an Oil and Gas Property affected by an Asserted
     Defect, then:

        (i) AGREE UPON ADJUSTMENT.  Buyer and Seller shall, with respect to each
     Property affected by such matters, attempt to agree upon an appropriate
     downward adjustment of the Purchase Price to account for such matters; and

        (ii) EXCLUDE PROPERTY.  With respect to each well or PUD location listed
     on Schedule I as to which Buyer and Seller are unable to agree upon
     appropriate adjustment with respect to all such matters affecting such well
     or PUD location, such well or PUD location (together with such related
     rights in any unit including the same, and other rights, as may be
     necessary or appropriate to own, operate and produce the same) will be
     excluded from the transaction contemplated hereby, and a downward
     adjustment of the Purchase Price will be made by the amount attributed on
     Schedule I to such well or PUD location.

        (b) CERTAIN ADJUSTMENTS.  In the event that Buyer raises as an Asserted
     Defect one of the following types of Defects, Seller may (but shall not be
     obligated to) propose the adjustment of the Purchase Price set forth below
     in connection with such Defect:

        (i) NRI VARIANCE/PROPORTIONATE PRICE REDUCTIONS.  If the Asserted Defect
     is (I) a Defect described in clause (A) of Section 7(b)(i) or (II) a Defect
     which otherwise affects a portion of Seller's interest in a well or PUD
     location listed on Schedule I:  a downward adjustment equal to the amount
     determined by multiplying the amount set forth for such well or PUD
     location on Schedule I by a fraction (A) the numerator of which is an
     amount equal to the "Net Revenue Interest" shown on Schedule I for such
     well or PUD location less the decimal share to which Seller

                                       14
<PAGE>

     would be entitled to as a result of its ownership interest in such well or
     PUD location which is unaffected by such Defect and (B) the denominator of
     which is the "Net Revenue Interest" shown for such well or PUD location on
     Schedule I. Notwithstanding subsection (ii) below, a Defect to which such
     subsection is applicable may, at Seller's election, be treated as a Defect
     under this subsection.

        (ii) LIENS/PAYOFF AMOUNT.  If the Asserted Defect is a Defect described
     in Section 7(b)(ii):  a downward adjustment equal to the amount of the debt
     secured by such lien.

     If Seller proposes such an adjustment, such adjustment will be deemed an
     adjustment agreed to under Section 8(a)(i) above.

        (c) LIMITATIONS ON ADJUSTMENTS.  If the Purchase Price reduction (or
     increase) with respect to a particular Asserted Defect which would result
     from the above provided for procedure does not exceed $25,000, no
     adjustment shall be made for such Asserted Defect.  If the Purchase Price
     reduction which would result from the above provided for procedure, as
     applied to all Asserted Defects for which an adjustment is to be made, does
     not exceed $250,000, then no adjustment of the Purchase Price shall occur,
     and none of the Properties which would be excluded by such procedure shall
     be excluded.  If the Purchase Price reduction which would result from the
     above provided for procedure, as applied to all Asserted Defects for which
     an adjustment is to be made exceeds $250,000, the Purchase Price shall be
     adjusted by the amount by which such reduction exceeds $250,000.

     9. CONDITIONS PRECEDENT TO THE OBLIGATIONS OF BUYER.  The obligations of
Buyer under this Agreement are subject to each of the following conditions being
met:

        (a) REPRESENTATIONS TRUE AND CORRECT.  Each and every representation of
     Seller under this Agreement shall be true and accurate in all material
     respects as of the date when made and shall be deemed to have been made
     again at and as of the time of Closing and shall at and as of such time of
     Closing be true and accurate in all material respects except as to changes
     specifically contemplated by this Agreement or consented to by Buyer.

        (b) COMPLIANCE WITH COVENANTS AND AGREEMENTS.  Seller shall have
     performed and complied in all material respects with (or compliance
     therewith shall have been waived by Buyer) each and every covenant and
     agreement required by this Agreement to be performed or complied with by
     Seller prior to or at the Closing.

        (c) PRICE ADJUSTMENT LIMITATIONS.  The aggregate downward adjustment (if
     any) of the Purchase Price which results from the procedures set forth in
     Section 8 does not exceed $2,600,000.

                                       15
<PAGE>

        (d) LITIGATION.  No suit, action or other proceedings shall, on the date
     of Closing, be pending or threatened before any court or governmental
     agency seeking to restrain, prohibit, or obtain material damages or other
     material relief in connection with the consummation of the transactions
     contemplated by this Agreement.

        (e) CONSENTS.  Seller shall have obtained all consents of third parties
     as required pursuant to the terms of the contracts identified in Paragraph
     4(a)(x) or the Disclosure Schedule.

     If any such condition on the obligations of Buyer under this Agreement is
not met as of the Closing Date, or in the event the Closing does not occur on or
before the Closing Date, and (in either case) Buyer is not in material breach of
its obligations hereunder in the absence of Seller being in material breach of
its obligations hereunder, this Agreement may, at the option of Buyer, be
terminated.  In the event such a termination by Buyer occurs the parties shall
have no further obligations to one another hereunder (other than the obligations
under Sections 3, 6(a)(iii) and 14 hereof all of which will survive such
termination).

     10.  CONDITIONS PRECEDENT TO THE OBLIGATIONS OF SELLER.  The obligations of
Seller under this Agreement are subject to the each of the following conditions
being met:

        (a) REPRESENTATIONS TRUE AND CORRECT.  Each and every representation of
     Buyer under this Agreement shall be true and accurate in all material
     respects as of the date when made and shall be deemed to have been made
     again at and as of the time of Closing and shall at and as of such time of
     Closing be true and accurate in all material respects except as to changes
     specifically contemplated by this Agreement or consented to by Seller.

        (b) COMPLIANCE WITH COVENANTS AND AGREEMENTS.  Buyer shall have
     performed and complied in all material respects with (or compliance
     therewith shall have been waived by Seller) each and every covenant and
     agreement required by this Agreement to be performed or complied with by
     Buyer prior to or at the Closing.

        (c) PRICE ADJUSTMENT LIMITATIONS.  The aggregate downward adjustment (if
     any) of the Purchase Price which results from the procedures set forth in
     Section 8 does not exceed $2,600,000.

        (d) LITIGATION.  No suit, action or other proceedings shall, on the date
     of Closing, be pending or threatened before any court or governmental
     agency seeking to restrain, prohibit, or obtain material damages or other
     material relief in connection with the consummation of the transactions
     contemplated by this Agreement.

     If any such condition on the obligations of Seller under this Agreement is
not met as of the Closing Date, or in the event the Closing does not occur on or
before the Closing Date, and

                                       16
<PAGE>

(in either case) Seller is not in material breach of its obligations hereunder
in the absence of Buyer being in material breach of its obligations hereunder,
this Agreement may, at the option of Seller, be terminated, in which case the
parties shall have no further obligations to one another hereunder (other than
the obligations under Sections 3, 6(a)(iii) and 14 hereof, all of which will
survive such termination).

     11.  CLOSING.

        (a) ACTIONS AT CLOSING.  The closing (herein called the "CLOSING") of
     the transaction contemplated hereby shall take place in the offices of
     Thompson & Knight LLP at 1700 Pacific Avenue, Dallas, Texas 75201, on or
     before May 31, 2000, at 10 a.m. Central Daylight Time, or at such other
     date and time (i) as the Buyer and Seller may mutually agree upon or (ii)
     to which Seller may postpone the Closing pursuant to Section 7 hereof (such
     date and time, as changed pursuant to clauses (i) and (ii), being herein
     called the "CLOSING DATE").  At the Closing:

        (i) DELIVERY OF CONVEYANCE.  Seller shall execute, acknowledge and
     deliver to Buyer a conveyance of the Properties (the "CONVEYANCE"), in the
     form attached hereto as Schedule III (and with Exhibit A hereto, with such
     modifications  as may be mutually agreed to by Buyer and Seller, being
     attached thereto), effective as to runs of oil and deliveries of gas and
     for all other purposes as of 7 o'clock a.m., local time at the locations of
     the Properties, respectively, on January 1, 2000 (herein called the
     "EFFECTIVE DATE").

        (ii) PAYMENT TO SELLER.  Buyer shall deliver to the C.W. Resources,
     Inc., by wire transfer of immediately available funds to an account
     designated by C.W. Resources, Inc. in a bank located in the United States,
     an amount equal to (A) the Purchase Price, plus (B) interest at the rate of
     8% per annum on an amount equal to the Base Purchase Price, as adjusted by
     any adjustments made under Section 8, from March 15, 2000 to (i) if Seller
     exercises its right under Section 7 to extend the Closing Date, May 31,
     2000, or (ii) otherwise, the Closing Date, less or plus (as the case may
     be) (C) any adjustments under Section 12 which are to be made at Closing,
     less (D) the Deposit.  Unless Seller has, at or before Closing, obtained
     the agreements contemplated by the fourth sentence of Section 11(b)(ii),
     the Operations Adjustment portion of the Purchase Price will not be
     required to be paid at Closing, and such payment to Seller will also be
     reduced by the amount of the Operations Adjustment plus any interest under
     clause (B) above attributable to that portion of the Purchase Price.  C.W.
     Resources, Inc. shall receive such amount on behalf of all parties
     constituting Seller, and Buyer, having so paid such amount, shall have no
     responsibility for the proper division of such amount among the parties
     constituting Seller.

                                       17
<PAGE>

        (iii)  TURN OVER POSSESSION.  Seller shall, to the extent Seller can do
     so, turn over possession of the Properties.

        (iv) SUCCESSION BY BUYER.  Buyer shall (A) furnish to Seller such
     evidence (including, without limitation, evidence of satisfaction of all
     applicable bonding requirements) as Seller may require that Buyer is
     qualified with the applicable authorities to succeed Seller as the owner
     and, where applicable, operator of the Properties, (B) with respect to
     properties operated by Seller where Buyer is to succeed Seller as operator,
     execute and deliver to Seller appropriate evidence reflecting change of
     operator as required by applicable authorities (including, without
     limitation, Form P-4 for filing with the Railroad Commission of Texas), and
     (C) execute and deliver to Seller such forms as Seller may reasonably
     request for filing with the applicable authorities to reflect Buyer's
     assumption of plugging and abandonment liabilities with respect to the
     wells located on the Properties or on units in which the Properties
     participate.

        (v) NON-FOREIGN STATUS TAX AFFIDAVIT.  If Buyer so requests, Seller will
     execute and deliver to Buyer an affidavit or other certification (as
     permitted by such code) that Seller is not a "foreign person" within the
     meaning of Section 1445 (or similar provisions) of the Internal Revenue
     Code of 1986 as amended (i.e., Seller is not a non-resident alien, foreign
     corporation, foreign partnership, foreign trust or foreign estate as those
     terms are defined in such code and regulations promulgated thereunder).

        (vi) FEDERAL AND STATE CONVEYANCE FORMS.  Seller shall, where
     appropriate, prepare, execute (and, where required, acknowledge) and
     deliver to Buyer forms of conveyance or assignment as required by the
     applicable authorities for transfers of interests in state and federal
     leases included in the Oil and Gas Properties.

        (vii)  LETTERS IN LIEU.  Seller shall, if requested by Buyer, prepare,
     execute and deliver to Buyer letters in lieu of transfer orders (or similar
     documentation), in form acceptable to both parties.

                                       18
<PAGE>

        (b)  POST CLOSING ACTIONS.

        (i) TRANSFER OF FILES.  Seller will use its best efforts to deliver to
     Buyer, at Buyer's expense, and within 15 days after Closing, all of
     Seller's lease files, abstracts and title opinions, division order files,
     production records, well files, accounting records (but not including
     general financial accounting or tax accounting records), and other similar
     files and records which directly relate to the Properties, provided that
     Seller shall not be obligated to turn over to Buyer any records or data
     which Seller believes that Seller cannot provide to Buyer without, in
     Seller's reasonable opinion, breaching, or risking a breach of, agreements
     with other parties, or waiving, or risking waiving, legal privilege.
     Notwithstanding the foregoing sentence, Seller shall provide Buyer a list
     of all records or data which Seller is withholding pursuant to such
     sentence to Buyer including a general description of such records' contents
     and the specific reason claimed by for Seller's for such withholding.

        (ii) BUYER AS SUCCESSOR OPERATOR.  Buyer desires to become successor
     operator with respect to as many of the Oil and Gas Properties operated by
     Seller as it can, other than the Oil and Gas Properties described in
     subsection 1(e) above.  IT IS RECOGNIZED THAT THERE IS NO ASSURANCE GIVEN
     BY SELLER THAT BUYER SHALL SUCCEED SELLER AS OPERATOR OF ANY PROPERTY WHERE
     OTHER PARTIES OWN INTERESTS IN THE WELLS LOCATED THEREON. Buyer and Seller
     agree to undertake reasonable efforts to cooperate toward accomplishing
     such goal.  If, despite its best efforts undertaken in good faith, Buyer is
     unable to obtain, on or before a date which is 120 days after Closing
     occurs, necessary agreements such that it will become such successor
     operator with respect to wells and units identified on Schedule I
     representing at least 90% of the value (determined based on the allocated
     amounts shown on Schedule I) of the wells and units identified on such
     Schedule I which are operated by Seller, then the Purchase Price will be
     reduced by an amount equal to $3,000,000 (the "OPERATIONS ADJUSTMENT");
     otherwise any portion of the Operations Adjustment not paid at Closing due
     to the next to last sentence of Section 11(a)(ii) (together with interest
     thereon at the rate of 8% per annum from March 15, 2000 until such payment
     is made) shall be paid to C.W. Resources, Inc. (in the same manner as
     payments under Section 11(a)(ii)) promptly after the agreements
     contemplated above are obtained and in any event not later than 125 days
     after Closing.

        (iii)  OPERATIONAL TRANSITION.  For a reasonable period of time after
     Closing, Buyer and Seller shall undertake reasonable efforts to cooperate
     with respect to transition activities as to Properties where Buyer succeeds
     Seller as operator.  To the extent Seller remains an operator after Closing
     (which it shall have no obligation to do), it shall serve as operator under
     the applicable operating agreement in the manner provided by such agreement
     and, to the extent Seller so operates any Property after Closing and/or
     provides disbursement services under subsection (iv)

                                       19
<PAGE>

     below, its obligations to Buyer with respect thereto shall be no greater
     than those which it would have to a non-operator under the applicable
     operating agreement (and, in the absence of an operating agreement, under
     the AAPL 610 (1989 Revision) form Operating Agreement), IT BEING RECOGNIZED
     THAT, UNDER SUCH AGREEMENTS AND SUCH FORM, THE OPERATOR IS NOT RESPONSIBLE
     FOR ITS OWN NEGLIGENCE, AND HAS NO RESPONSIBILITY OTHER THAN FOR GROSS
     NEGLIGENCE OR WILFUL MISCONDUCT.

        (iv) TRANSITION OF CERTAIN ACCOUNTING MATTERS.  With respect to each Oil
     and Gas Property as to which Buyer becomes successor operator and with
     respect to which Seller is disbursing proceeds of production attributable
     to other parties entitled thereto, (i) Seller shall continue to receive
     such proceeds of production up to the Closing and, to the extent it
     actually receives such proceeds, shall be responsible for making
     disbursements, in accordance with its normal procedures (and at normal
     times), of such proceeds of production to the parties entitled to same,
     with any such proceeds of production after the Closing received by Seller
     to be promptly forwarded to Buyer (who shall thereafter account for same to
     the parties entitled thereto) and Seller shall, as promptly as possible
     after Closing, deliver to Buyer a copy of its "pay list" for each such
     property (which list shall include the names of all parties for whom it is
     holding in suspense proceeds of production).  Seller will retain all
     suspense funds, and responsibility therefor, and such suspense funds, and
     Seller's handling thereof, shall be included in the matters which Seller
     indemnifies Buyer with respect to, under Section 13 below.  Following
     delivery of the materials referred to above, Buyer shall become responsible
     for all disbursements of proceeds of production from such properties and
     such disbursement activities shall be included in the matters which Buyer
     assumes, and indemnifies Seller with respect to, under Section 13 below.

     12.  CERTAIN ACCOUNTING ADJUSTMENTS.

        (a) ADJUSTMENTS FOR REVENUES AND EXPENSES.  Appropriate adjustments
     shall be made between Buyer and Seller so that (i) Buyer will bear all
     expenses which are incurred in the operation of the Properties after the
     Effective Date (including, without limitation, all drilling costs, all
     capital expenditures, all overhead charges under applicable operating
     agreements (regardless of whether such operating agreements are with third
     parties or related entities and regardless of whether Seller is the
     operator or a non-operator)), and all other overhead charges actually
     charged by Seller (and for which Seller bills third parties for their
     respective shares) or charged to Seller by third parties, and operating
     expenses), and Buyer will receive all proceeds (net of applicable
     production, severance, and similar taxes) from sales of oil, gas and/or
     other minerals which are produced from (or attributable to) the Properties
     and which are produced after the Effective Date, and (ii) Seller will bear
     all expenses which are incurred in the

                                       20
<PAGE>

     operation of the Properties before the Effective Date and Seller will
     receive all proceeds (net of applicable production, severance, and similar
     taxes) from the sale of oil, gas and/or other minerals which were produced
     from (or attributable to) the Properties and which were produced before the
     Effective Date. It is agreed that, in making such adjustments: (i) oil
     which was produced from the Oil and Gas Properties and which was, on the
     Effective Date, stored in tanks located on the Oil and Gas Properties (or
     located elsewhere but used by Seller to store oil produced from, or
     attributable to, the Oil and Gas Properties prior to delivery to oil
     purchasers) and above pipeline connections shall be deemed to have been
     produced before the Effective Date, (ii) ad valorem and similar taxes
     assessed for periods prior to the Effective Date shall be borne by Seller
     and ad valorem taxes assessed for periods on or after the Effective Date
     shall be borne by Buyer, (iii) ad valorem and similar taxes assessed with
     respect to a period which the Effective Date splits shall be prorated based
     on the number of days in such period which fall on each side of the
     Effective Date (with the day on which the Effective Date falls being
     counted in the period after the Effective Date), (iv) casualty losses shall
     be handled in accordance with Section 15, and (v) no consideration shall be
     given to the local, state or federal income tax liabilities of any party.

        (b) INITIAL ADJUSTMENT AT CLOSING.  At least 5 days before the Closing
     Date, Seller shall provide to Buyer a statement showing its computations of
     the amount of the adjustments provided for in subsection (a) above based on
     amounts which prior to such time have actually been paid or received by
     Seller.  Buyer and Seller shall attempt to agree upon such adjustments
     prior to Closing, provided that if agreement is not reached, Seller's
     computation shall be used at Closing, subject to further adjustment under
     subsection (c) below.  If the amount of adjustments so determined which
     would result in a credit to Buyer exceed the amount of adjustments so
     determined which would result in a credit to Seller, Buyer shall receive a
     credit at Closing for the amount of such excess, and if the converse is
     true, then the amount to be paid by Buyer to Seller at Closing shall be
     increased by the amount of such excess.

        (c) ADJUSTMENT POST CLOSING.  On or before 120 days after Closing,
     Seller shall provide to Buyer a statement showing its computations
     regarding any information which may then be available pertaining to the
     adjustments provided for in subsection (a) above, and Buyer shall review
     such statement.  Buyer and Seller shall determine if Seller's statement
     accurately reflects any additional adjustments that should be made beyond
     those made at Closing (whether the same be made to account for expenses or
     revenues not considered in making the adjustments made at Closing, or to
     correct errors made in the adjustments made at Closing), and shall make any
     such adjustments by appropriate payments from Seller to Buyer or from Buyer
     to Seller.  After such adjustments are made, no further adjustments shall
     be made under this Section 12.

     13.  ASSUMPTION AND INDEMNIFICATION.   Except as provided in Section 18(b)
below with respect to the JW Litigation (below defined), and except for matters
which would constitute

                                       21
<PAGE>

breaches of the express representations and warranties of Seller set forth in
Section 4(a) above, Buyer shall, on the date of Closing, agree (and, upon the
delivery to Buyer of the Conveyance, shall be deemed to have agreed) (a) to
assume, and to timely pay and perform, all duties, obligations and liabilities
relating to the ownership and/or operation of the Properties after the Effective
Date (including, without limitation, those arising under the contracts and
agreements described in Section 1(c) above), and (b) to indemnify and hold
Seller (and the respective affiliates of the parties constituting Seller, and
the respective directors, officers, employees, attorneys, contractors and agents
of such affiliates and such parties) harmless from and against any and all
claims, actions, causes of action, liabilities, damages, losses, costs or
expenses (including, without limitation, court costs and attorneys' fees) of any
kind or character arising out of or otherwise relating to either (A) the
ownership and/or operation of the Properties after the Effective Date or (B) a
breach of Buyer's express representations and warranties set forth in Section 5
above. In connection with (but not in limitation of) the foregoing, it is
specifically understood and agreed that such duties, obligations and liabilities
arising out or otherwise relating to the ownership and/or operation of the
Properties after the Effective Date (other than matters which should have been
disclosed under Section 4(a)(vii) above, but were not) shall (notwithstanding
anything herein appearing to be to the contrary) be deemed to include all
matters arising out of the condition of the Properties on the Effective Date
(including, without limitation, within such matters all obligations to properly
plug and abandon, or replug and re-abandon, wells located on the Properties, to
restore the surface of the Properties and to comply with, or to bring the
Properties into compliance with, applicable environmental laws, rules,
regulations and orders, including conducting any remediation activities which
may be required on or otherwise in connection with activities on the
Properties), regardless of whether such condition or the events giving rise to
such condition arose or occurred before or after the Effective Date, and the
assumptions and indemnifications by Buyer provided for in the first sentence of
this section shall expressly cover and include such matters. Seller shall, on
the date of Closing, agree (and, upon the delivery to Buyer of the Conveyance
shall be deemed to have agreed) to indemnify and hold Buyer (and its affiliates,
and the respective directors, officers, employees, attorneys, contractors and
agents of such parties) harmless from and against any and all claims, actions,
causes of action, liabilities, damages, losses, costs or expenses (including,
without limitation, court costs and attorneys' fees) of any kind or character
arising out of or otherwise relating to either (A) the ownership and/or
operation of the Properties prior to the Effective Date, except to the extent
the same arise out of the condition of the Properties (such matters having been
provided for above), and except to the extent the same arise out of any matter
disclosed on the Disclosure Schedule (other than the litigation for which Seller
retains responsibility under Section 18(b) below, which is covered by such
Section 18(b)), or out of any matter made the subject of an Asserted Defect
pursuant to Section 7 above or (B) a breach of Seller's express representations
and warranties set forth in Section 4(a) above. In the event of any conflict
which may appear to exist between this Section and Section 12 above, this
Section shall control. THE FOREGOING ASSUMPTIONS AND INDEMNIFICATIONS SHALL
APPLY WHETHER OR NOT SUCH DUTIES, OBLIGATIONS OR LIABILITIES, OR SUCH CLAIMS,
ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES ARISE
OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE

                                       22
<PAGE>

NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY
NOT INCLUDING GROSS NEGLIGENCE) OF ANY INDEMNIFIED PARTY, OR (ii) STRICT
LIABILITY.

     14.  NO COMMISSIONS OWED.  Seller agrees to indemnify and hold Buyer (and
its affiliates, and the respective officers, directors, employees, attorneys,
contractors and agents of Buyer and such parties) harmless from and against any
and all claims, actions, causes of action, liabilities, damages, losses, costs
or expenses (including, without limitation, court costs and attorneys' fees) of
any kind or character arising out of or resulting from any agreement,
arrangement or understanding alleged to have been made by, or on behalf of,
Seller with any broker or finder in connection with this Agreement or the
transaction contemplated hereby.  Buyer agrees to indemnify and hold Seller (and
the respective affiliates of the parties constituting Seller, and the respective
officers, directors, employees, attorneys, contractors and agents of such
affiliates and such parties) harmless from and against any and all claims,
actions, causes of action, liabilities, damages, losses, costs or expenses
(including, without limitation, court costs and attorneys' fees) of any kind or
character arising out of or resulting from any agreement, arrangement or
understanding alleged to have been made by, or on behalf of, Buyer with any
broker or finder in connection with this Agreement or the transaction
contemplated hereby.

     15.  CASUALTY LOSS.  In the event of damage by fire or other casualty to
the Properties prior to the Closing, this Agreement shall remain in full force
and effect, and in such event:

        (a) OIL AND GAS PROPERTIES.  As to each such Property so damaged which
     is an Oil and Gas Property, then (unless Seller elects to repair such
     damage, which Seller shall have no obligation to do, in which case all
     rights to insurance proceeds related thereto shall belong to Seller), (i)
     at the election of either Buyer of Seller, such Property shall be treated
     as if it had an Asserted Defect associated with it and the procedure
     provided for in Section 8 shall be applicable thereto (in which case,
     unless Buyer and Seller agree to the contrary, all rights to insurance
     proceeds related thereto shall belong to Seller), or, (ii) if no such
     election is made by Buyer or Seller, the Purchase Price will not be
     adjusted, and Seller shall, at Seller's election, either collect (and when
     collected pay over to Buyer) any insurance claims related to such damage,
     or assign to Buyer such insurance claims, and, in either event, Buyer shall
     take title to the Property affected by such loss without reduction of the
     Purchase Price.

        (b) OTHER PROPERTIES.  As to each such Property so damaged which is
     other than an Oil and Gas Property, Seller shall, at Seller's election,
     either (i) repair such damage or replace such Property, (ii) collect (and
     when collected pay over to Buyer) any insurance claims related to such
     damage, or (iii) assign to Buyer any insurance claims related to such
     damage, and Buyer shall take title to the Property affected by such loss
     without reduction of the Purchase Price.

Seller has no obligation to carry insurance coverage, or to carry any particular
types or amounts

                                       23
<PAGE>

of coverage, and, in the event of a loss which is not covered by insurance,
Seller shall have no obligation to Buyer with respect thereto.

     16.  NOTICES.  All notices and other communications required under this
Agreement shall (unless otherwise specifically provided herein) be in writing
and be delivered personally, by recognized commercial courier or delivery
service which provides a receipt, by telecopier (with receipt acknowledged), or
by registered or certified mail (postage prepaid), at the following addresses:

     17.  SURVIVAL OF PROVISIONS.  All representations and warranties made
herein by Buyer and Seller shall be continuing and shall be true and correct on
and as of the date of Closing with

                                       24
<PAGE>

the same force and effect as if made at that time (and shall inure to the
benefit of the respective successors and assigns of Buyer and Seller), and all
of such representations and warranties shall, survive the Closing and the
delivery of the Conveyance indefinitely, except that other than those set forth
in Section 4(a)(i) through 4(a)(v) above, representations and warranties of
Seller shall terminate six months after the Closing Date. The provisions of
Section 11 (to the extent the same are, by mutual agreement, not performed at
Closing), and Sections 12, 14, 16 and 18 shall (subject to any limitations set
forth therein) survive the Closing and delivery of the conveyance indefinitely.
The obligations of Buyer under Section 13 shall survive the Closing and the
delivery of the Conveyance indefinitely, and the obligations of Seller under
Section 13 shall also survive the Closing and the delivery of the Conveyance,
but (i) except as provided in subsections (ii) and (iii) below, shall terminate
one year after the Closing Date, and (ii) as to breaches of Seller's
representations and warranties, shall terminate when such representations and
warranties terminate (as provided above), and (iii) as to proper payment of
royalties due with respect to the Oil and Gas Properties under leases (interests
in which are included in the Oil and Gas Properties), or any matter that should
have been disclosed in connection with Section 4(a)(v), but was not, or any
matter that should have been disclosed in connection with Section 4(a)(vii), but
was not, shall terminate two years after the Closing Date.

     18.  MISCELLANEOUS MATTERS.

        (a) FURTHER ASSURANCES.  After the Closing, Seller shall execute and
     deliver, and shall otherwise cause to be executed and delivered, from time
     to time, such further instruments, notices, division orders, transfer
     orders and other documents, and do such other and further acts and things,
     as may be reasonably necessary to more fully and effectively grant, convey
     and assign the Properties to Buyer.

        (b) JW LITIGATION, OTHER LITIGATION.  The parties acknowledge the
     existence of that certain lawsuit styled Wagner & Brown, Ltd. vs. H.G.,
     Westerman vs. C.W. Resources, Inc., et al. (Cause No 41,534), 238th
     Judicial District Court, Midland County, Texas (the "JW LITIGATION") and
     agree that the existence of the JW Litigation shall in no way interfere
     with the consummation of the transaction contemplated hereby.  Seller shall
     retain full responsibility, and full control, over such JW Litigation,
     handling it (including, without limitation, decisions on litigation
     strategy, decisions to settle (and settlement terms) or prosecute the same
     and/or decisions to appeal or not appeal any judgment) in its sole,
     unfettered discretion, and at its sole cost (including cost of settlement
     or payment of judgment, if any) and with it having sole right to any
     amounts (including any settlement or judgment amounts) paid by other
     parties thereto.  Seller shall indemnify and hold Buyer (and its
     affiliates, and the respective officers, directors, employees, attorneys,
     contractors and agents of Buyer and such affiliates) harmless from and
     against any and all claims, actions, causes of action, liabilities,
     damages, losses, costs or expenses (including court costs and attorneys'
     fees, except attorneys' fees, and costs, for attorneys, if any, employed by
     Buyer) of any kind arising out of or resulting from such JW Litigation.

                                       25
<PAGE>

     Notwithstanding anything in the foregoing appearing to the contrary, if, as
     a result of a settlement of such JW Litigation, or a final nonappealable
     judgment with respect thereto, title to any portion of the Properties
     conveyed to Buyer pursuant to this agreement is lost, Seller's liability
     for such loss shall be an amount computed in the same manner as if such
     loss had been Defects handled under Section 8(b)(i), and such amount (which
     shall be paid to Buyer promptly after such settlement or judgment is
     finalized) shall be deemed to fully compensate Buyer for such loss; Buyer
     recognizes such risk of title loss, and, in the event the same occurs,
     agrees to relinquish the lost interest and account for revenues received
     (less expenses paid) by it with respect thereto.  Seller shall also retain
     responsibility, and full control, over those certain lawsuits styled Jane
     Turner Sheppard, et al vs. C.W. Resources, et al, Jerrell L. McBride vs.
     Clarence N. Schwab dba CNS Energy, et al, vs. Procom Energy, Inc., W. L.
     Dixon, et al vs. Amoco Production Company, et al (each disclosed on the
     Disclosure Schedule) (the "CERTAIN LITIGATION"), in the same manner, and on
     the same terms, as provided above for the JW Litigation.  Buyer will assume
     full responsibility for, and control over, all litigation disclosed on the
     Disclosure Schedule other than the JW Litigation and the Certain
     Litigation, with such assumption of responsibility and control to be on the
     same basis as provided above for Seller's responsibility for, and control
     over, the JW Litigation (except that, of course, the language providing for
     certain matters in the event of a loss of title by Buyer will be
     inapplicable).  The party having responsibility for and control of a
     litigation matter shall be entitled to receive, from the other party, and
     it is agreed that the other party shall give, its cooperation in the
     handling of such litigation (for example, and without limitation, Seller
     agrees to make its employees available for depositions, if any, and for
     testimony at any trial); similarly, the party handling a litigation matter
     will cooperate with the other party so as to minimize the impact on the
     other party's business operations to the extent reasonably possible.  It is
     agreed that the total out-of-pocket cost (including attorneys' fees, any
     settlement payments and payment of any judgement) to Buyer of handling the
     C.W. Resources, Inc. et al. vs. Valence Operating Company matter
     (identified on the Disclosure Schedule) shall be limited to $200,000 and
     that Seller will bear all out-of-pocket costs in excess of such amount;
     provided that Seller may, at any time, elect (by notice in writing to
     Buyer) to take over responsibility for, and control of, such matter (on the
     same basis as provided above for Seller's responsibility for, and control
     over, the JW Litigation), and Buyer shall have no further obligation for
     out-of-pocket costs incurred after Seller actually takes over such matter.

        (c) SHALLOW COMPLETION IN HAYNESVILLE WELL.  Should a well drilled to
     the Haynesville Formation under the Oil and Gas Properties described in
     Section 1(e) above not be completed in such formation, it is recognized
     that Buyer, as the owner of rights to depths above such formation, may take
     over Seller's interest in such well prior to its abandonment, but if Buyer
     elects to do so, it shall reimburse Seller for its portion of the cost of
     drilling such well which would be attributable to drilling such well to a
     depth sufficient to attempt a Cotton Valley Sand Formation completion.

                                       26
<PAGE>

        (d) DECEPTIVE TRADE PRACTICES WAIVER.  TO THE EXTENT APPLICABLE TO THE
     TRANSACTION CONTEMPLATED HEREBY OR ANY PORTION THEREOF, BUYER WAIVES
     BUYER'S RIGHTS UNDER THE PROVISIONS OF THE TEXAS DECEPTIVE TRADE PRACTICES
     - CONSUMER PROTECTION ACT, SECTIONS 17.41 ET. SEQ. OF THE TEXAS BUSINESS
     AND COMMERCE CODE, A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND
     PROTECTIONS, AND ANY COMPARABLE ACT IN ANY OTHER STATE IN WHICH THE
     PROPERTIES ARE LOCATED.  BUYER STATES THAT, AFTER CONSULTATION WITH AN
     ATTORNEY OF BUYER'S SELECTION, BUYER VOLUNTARILY CONSENTS TO THIS WAIVER.

        (e) PARTIES BEAR OWN EXPENSES/NO SPECIAL DAMAGES.  Each party shall bear
     and pay all expenses (including, without limitation, legal fees) incurred
     by it in connection with the transaction contemplated by this Agreement.
     NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY NEITHER PARTY SHALL HAVE
     ANY OBLIGATIONS WITH RESPECT TO THIS AGREEMENT, OR OTHERWISE IN CONNECTION
     HEREWITH, FOR ANY SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES.

        (f) NO SALES TAXES.  No sales, transfer or similar tax will be collected
     at Closing from Buyer in connection with this transaction.  If, however,
     this transaction is later deemed to be subject to sales, transfer or
     similar tax, for any reason, Buyer agrees to be solely responsible, and
     shall indemnify and hold Seller (and its affiliates, and its and their
     directors, officers, employees, attorneys, contractors and agents)
     harmless, for any and all sales, transfer or other similar taxes (including
     related penalty, interest or legal costs) due by virtue of this transaction
     on the Properties transferred pursuant hereto and the Buyer shall remit
     such taxes at that time.  Seller and Buyer agree to cooperate with each
     other in demonstrating that the requirements for exemptions from such taxes
     have been met.

        (g) ENTIRE AGREEMENT.  This Agreement contains the entire understanding
     of the parties hereto with respect to subject matter hereof and supersedes
     all prior agreements, understandings, negotiations, and discussions among
     the parties with respect to such subject matter; provided that any
     Confidentiality Agreement executed by Buyer and Seller, or any
     representative of Seller, in connection with the transaction contemplated
     hereby remains in full force and effect and is not superseded or modified
     by this Agreement.

        (h) AMENDMENTS, WAIVERS.  This Agreement may be amended, modified,
     supplemented, restated or discharged (and provisions hereof may be waived)
     only by an instrument in writing signed by the party against whom
     enforcement of the amendment, modification, supplement, restatement or
     discharge (or waiver) is sought.

        (i) CHOICE OF LAW.  Without regard to principles of conflicts of law,
     this Agreement shall be construed and enforced in accordance with and
     governed by the laws of the state of Texas applicable to contracts made and
     to be performed entirely within such state and the laws of the United
     States of America, except that, to the extent that the law of a state in
     which a portion of the Properties is located (or which is otherwise

                                       27
<PAGE>

     applicable to a portion of the Properties) necessary governs, the law of
     such state shall apply as to that portion of the property located in (or
     otherwise subject to the laws of) such state.

        (j) HEADINGS, TIME OF ESSENCE, ETC.  The descriptive headings contained
     in this Agreement are for convenience only and shall not control or affect
     the meaning or construction of any provision of this Agreement.  Within
     this Agreement words of any gender shall be held and construed to cover any
     other gender, and words in the singular shall be held and construed to
     cover the plural, unless the context otherwise requires.  Time is of the
     essence in this Agreement.

        (k) NO ASSIGNMENT.  Prior to Closing, neither party shall have the right
     to assign its rights under this Agreement, without the prior written
     consent of the other party first having been obtained.

        (l) LIKE KIND EXCHANGE.  Seller may elect to structure this transaction
     as a like-kind exchange pursuant to Section 1031 of the Internal Revenue
     Code of 1986, as amended, and the regulations promulgated thereunder, with
     respect to any or all of the Properties (a "Like-Kind Exchange") at any
     time prior to the date of Closing.  In order to effect a Like-Kind
     Exchange, Buyer shall cooperate and do all acts as may be reasonably
     required or requested by Seller with regard to effecting the Like-Kind
     Exchange, including, but not limited to, permitting Seller to assign its
     rights under this Agreement to a qualified intermediary of Seller's choice
     in accordance with Treasury Regulation 1.1031(k)-1(g)(4) or executing
     additional escrow instructions, documents, agreements or instruments to
     effect an exchange; provided, however, Buyer shall incur no expense in
     connection with such Like-Kind Exchange, Buyer shall not be required to
     take title to any property other than the Properties in connection with the
     Like-Kind Exchange, and Buyer's possession of the Properties will not be
     delayed by reason of any such Like-Kind Exchange.

        (m) SUCCESSORS AND ASSIGNS.  Subject to the limitation on assignment
     contained in subsection (k) above, the Agreement shall be binding on and
     inure to the benefit of the parties hereto and their respective successors
     and assigns.

        (n) COUNTERPART EXECUTION.  This Agreement may be executed in
     counterparts, all of which are identical and all of which constitute one
     and the same instrument.  It shall not be necessary for Buyer and Seller to
     sign the same counterpart.

                                       28
<PAGE>

     IN WITNESS WHEREOF, this Agreement is executed by the parties hereto on the
date set forth above.
