                              FOR ALL OUTSTANDING

                         MICHAEL PETROLEUM CORPORATION

                             ----------------------
   
      THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
MONDAY, AUGUST 31, 1998, UNLESS EXTENDED.
    

   
    Michael Petroleum Corporation (the "Company") is offering upon the terms and
subject to the conditions set forth in this Prospectus and the accompanying
letter of transmittal (the "Letter of Transmittal") (which together constitute
the "Exchange Offer") to exchange $1,000 principal amount of its new 11 1/2%
Senior Notes due 2005, Series B (the "New Notes") for each $1,000 principal
amount of its outstanding 11 1/2% Senior Notes due 2005, Series A (the "Old
Notes") in the aggregate principal amount of $135,000,000.  The form and terms
of the New Notes are identical to the form and terms of the Old Notes, except
that the Old Notes were offered and sold in reliance upon certain exemptions
from registration under the Securities Act of 1933, as amended (the "Securities
Act"), while the offering and sale of the New Notes in exchange for the Old
Notes have been registered under the Securities Act, with the result that the
New Notes will not bear any legends restricting their transfer.  The New Notes
will evidence the same debt as the Old Notes and will be issued pursuant to, and
entitled to the benefits of, the indenture governing the Old Notes (the
"Indenture").  The Exchange Offer is being made in order to satisfy certain
contractual obligations of the Company.  See "The Exchange Offer" and
"Description of Notes."  The New Notes and the Old Notes are sometimes
collectively referred to herein as the "Notes."
    

   
    The New Notes will mature on April 1, 2005.  The Notes will be redeemable at
the option of the Company, in whole or in part, at any time on or after April 1,
2003, at the redemption prices set forth herein, plus accrued and unpaid
interest and Liquidated Damages, if any, to the redemption date. The Company may
also redeem at its option at any time prior to April 1, 2001, up to 30% of the
aggregate principal amount of the Notes originally issued at a redemption price
of 111.5% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, to the date of redemption, with the proceeds of one
or more offerings of the Company's equity securities, provided that at least 65%
of the aggregate principal amount of the Notes originally issued remains
outstanding following each redemption and each such redemption occurs within 90
days after the date of the closing of each such Equity Offering.  Upon a Change
of Control, the Company will be required to offer to purchase all outstanding
Notes at 101% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of purchase. However, there can be
no assurance that the Company would have or be able to acquire sufficient funds
to repurchase the Notes in such an event. See "Description of Notes." The Notes
will be transferable, subject to compliance with applicable federal and state
securities laws.
    

   
    The New Notes will be senior unsecured obligations of the Company and will
rank in parity with all existing and future senior indebtedness and other senior
obligations of the Company in right of payment, and senior in right of payment
to all future subordinated indebtedness of the Company.  Borrowings under the
Company's reducing revolving credit facility (the "Credit Facility") are secured
by substantially all of the oil and natural gas properties of the Company.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Financing Arrangements."  Because any indebtedness under the
Company's Credit Facility will be secured, the indebtedness under the Notes is
effectively subordinated to the Credit Facility. See "Risk Factors -- Effective
Subordination of the Notes." The maximum amount of borrowings under the Credit
Facility is limited by the terms of the Notes. At May 31, 1998, the Company had
outstanding indebtedness for borrowed money of $135.0 million.
    

    Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes, where the Old Notes were acquired by that broker-dealer as a
result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes.  This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Notes received in exchange for Old Notes where such Old Notes were acquired as
a result of market-making activities or other trading activities. See "The
Exchange Offer" and "Plan of Distribution."

    The Company will accept for exchange any and all validly tendered Old Notes
on or before 5:00 p.m., New York City time, on Monday, August 31, 1998, unless
extended (the "Expiration Date"). Prior to the Expiration Date, the Company
will continue to update the Prospectus. Tenders of Old Notes may be withdrawn at
any time before 5:00 p.m., New York City time, on the Expiration Date, but after
that time are irrevocable.  State Street Bank and Trust Company will be acting
as Exchange Agent in connection with the Exchange Offer. The Exchange Offer is
not conditioned on any minimum principal amount of Old Notes being tendered for
exchange, but is otherwise subject to certain customary conditions.
    

    The New Notes will bear interest from the most recent date to which
interest has been paid on the Old Notes or, if no interest has been paid, from
the date of issuance of the Old Notes at a rate per annum of 11 1/2%.  Interest
on the New Notes will be payable semiannually on October 1 and April 1 of each
year commencing on the first such date following the date of issuance of the
New Notes.  Old Notes that are accepted for exchange will cease to accrue
interest on and after the date on which interest on the New Notes begins to
accrue.  Accrued and unpaid interest on the Old Notes that are tendered in
exchange for the New Notes will be payable on the first October 1 or April 1
following the date of issuance of the New Notes.

    The Old Notes were issued and sold by the Company on April 2, 1998, to
Bear, Stearns & Co. Inc., Jefferies & Company, Inc. and Raymond James &
Associates, Inc. (the "Initial Purchasers") in transactions not registered
under the Securities Act in reliance on the exemption provided in Section 4(2)
of the Securities Act.  The Initial Purchasers subsequently placed the Old
Notes with qualified institutional buyers in reliance on Rule 144A under the
Securities Act or outside the United States within the meaning of Regulation S
under the Securities Act, the purchasers of which agreed to comply with certain
transfer and other restrictions.  Accordingly, the Old Notes may not be
reoffered, resold or otherwise transferred in the United States unless so
registered or unless an applicable exemption from the registration requirements
of the Securities Act is available. The New Notes are being offered hereunder
in order to satisfy the obligations of the Company under a Registration Rights
Agreement entered into between the Company and the Initial Purchasers (the
"Registration Rights Agreement").  See "The Exchange Offer."

    Based on an interpretation by the staff of the Securities and Exchange
Commission (the "Commission" or the "SEC") set forth in no-action letters
issued to third parties, the Company believes that New Notes issued pursuant to
this Exchange Offer may be offered for resale, resold and otherwise transferred
by a holder who is not an affiliate of the Company without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that the holder is acquiring the New Notes in its ordinary course of business
and is not participating in and has no arrangement or understanding with any
person to participate in the distribution (within the meaning of the Securities
Act) of the New Notes.  Persons wishing to exchange Old Notes in the Exchange
Offer must represent to the Company that these conditions have been met.

    The Company does not intend to list the New Notes on any national
securities exchange or to seek the admission thereof to trading in the National
Association of Securities Dealers Automated Quotation System.  The Initial
Purchasers have advised the Company that they intend to make a market in the
New Notes; however, they are not obligated to do so and any market-making may
be discontinued at any time without notice.  Accordingly, no assurance can be
given that an active public or other market will develop for the New Notes or
as to the liquidity of or the trading market for the New Notes.

    Any Old Notes not tendered and accepted in the Exchange Offer will remain
outstanding.  To the extent that any Old Notes are tendered and accepted in the
Exchange Offer, a holder's ability to sell untendered Old Notes could be
adversely affected.  Following consummation of the Exchange Offer, the holders
of Old Notes will continue to be subject to the existing restrictions on
transfer thereof.

   
    The Company expects that the New Notes issued pursuant to this Exchange
Offer will be issued in the form of a Global New Note which will be deposited
with, or on behalf of, The Depository Trust Company ("DTC") and registered in
its name or in the name of Cede & Co., its nominee.  Beneficial interests in the
Global New Note representing the New Notes will be shown on, and transfers
thereof to qualified institutional buyers will be effected through, records
maintained by DTC and its participants.  After the initial issuance of the
Global New Note, New Notes in certificated form will be issued in exchange for
the Global New Note on the terms set forth in the Indenture. See "Description of
Notes--Book Entry; Delivery and Form."

                                    SUMMARY

   
    The following summary is qualified in its entirety by and should be read in
conjunction with the more detailed information, financial statements, including
notes thereto, and other data appearing elsewhere in this Prospectus.  Unless
the context indicates otherwise, references to "Michael" or the "Company" are to
Michael Petroleum Corporation.  References to "MHI" are to Michael Holdings,
Inc., which directly owns all of the outstanding capital stock of the Company.
References to the "Notes" refer to both the Old Notes and the New Notes. Unless
otherwise indicated, all financial and quantitative information provided in this
Prospectus on a "pro forma" basis gives effect, on the date and for the periods
indicated, to the issuance of the Old Notes and the exchange of the Old Notes
for New Notes, the application of the net proceeds from the sale of the Old
Notes and the completion of the Transactions and the execution and delivery of
the Lobo Lease as if such events had already occurred. Investors should
carefully consider the information set forth under "Risk Factors" herein.
Certain oil and natural gas terms used in this Prospectus are defined in the
"Glossary of Certain Industry Terms" appearing elsewhere in this Prospectus.
    

                                  THE COMPANY

    The Company is engaged in the acquisition, exploitation and development of
oil and natural gas properties, principally in the Lobo Trend of South Texas
(the "Lobo Trend"). The Company has significantly expanded its production and
reserve base in recent years through development drilling and exploitation
activities and by acquiring producing and undeveloped properties.  On March 31
and April 2, 1998, the Company closed separate acquisitions of Lobo Trend
properties with Enron Oil and Gas Company ("Enron") (the "Enron Acquisition")
and Conoco Inc. ("Conoco") (the "Conoco Acquisition") (collectively, the
"Transactions"), pursuant to which the Company acquired interests in 170 gross
(98 net) wells covering approximately 46,900 gross acres and proved reserves of
96 Bcfe as of December 31, 1997. On April 20, 1998, the Company entered into
agreements with Mobil Producing Texas and New Mexico Inc. ("Mobil"), pursuant to
which the Company acquired leasehold interests in undeveloped acreage from Mobil
(the "Lobo Lease"), covering approximately 39,636 gross acres in the Lobo Trend,
adding 43 Bcfe of net proved undeveloped reserves as of December 31, 1997.  The
interests in properties acquired included acreage that is geographically close
and geologically similar to the Company's other properties. The Company believes
that these acquired properties together with its previously existing properties
have substantial development drilling and exploitation potential. The Company
has initially identified approximately 160 drilling locations that are expected
to be drilled over the next several years. The Company used approximately $68.3
million of the net proceeds from the sale of the Old Notes in connection with
the closing of the Transactions, including the repayment of short-term
acquisition indebtedness incurred in connection with the closing of the Enron
Acquisition.  At December 31, 1997, on a pro forma basis, the Company owned
interests in 280 gross (159 net) wells, approximately 95% of which were operated
by the Company, and had proved reserves totaling 191 Bcfe, with a PV-10 Value of
$203 million.

    The Lobo Trend, which is located in Webb and Zapata counties in South
Texas, covers in excess of one million gross acres and contains multi-pay
reservoirs of oil and natural gas. Since 1991, Webb and Zapata counties
collectively have constituted one of the largest onshore natural gas producing
regions in the United States. Although over 3,500 wells have been drilled and
cumulative production from the Lobo Trend since its discovery in 1973 exceeds
6.3 trillion cubic feet of natural gas equivalents, the Lobo Trend is believed
to be only partially exploited, with existing wells producing from only
approximately 125,000 acres. The primary geologic target in the Lobo Trend is
the Lobo sand series of the lower Wilcox formation, which contains three
primary objectives. Two secondary objectives also exist, one above the three
Lobo sands and one below. The Company believes that the existence of these
multi-pay reservoirs reduces drilling risk and enhances the profitability of
invested capital.

    The Company began its operations in 1983 and focused on developing
prospects in South Texas. Since the early 1990s, the Company has become an
increasingly active participant in lower risk development drilling in the Lobo
Trend, and in 1996 the Company acquired interests in approximately 21,000
developed and undeveloped gross acres in the Lobo Trend. The Company uses 3-D
seismic imaging and other advanced exploration technologies in the development
and exploitation of its properties. As of December 31, 1997, on a pro forma
basis, 3-D seismic data had been obtained over approximately 90% of the
Company's properties. Based upon the Company's interpretation of 3-D seismic
data and wells drilled in the area, the Company has initially identified, on a
pro forma basis, approximately 160 drilling locations on its properties, 90 of
which are in the Company's proved undeveloped reserve base. During 1998, the
Company intends to drill approximately 29 gross (25 net) wells and has
allocated approximately $23.3 million of its capital expenditure budget for
this purpose.  All of the Company's drilling prospects for 1998, on a pro forma
basis, were identified through the use of 3-D seismic data.

    The principal executive offices of the Company are located at 13101
Northwest Freeway, Suite 320, Houston, Texas 77040, and its telephone number is

                               BUSINESS STRATEGY

    Key elements of the Company's business strategy include the following:

   
    CONTINUE EXPLOITATION AND DEVELOPMENT PROGRAM. The Company intends to
further develop and exploit its properties, including the interests in the
properties acquired in the Transactions and subject to the Lobo Lease, which,
in the aggregate, currently include approximately 160 identified drilling
locations. The Company's development and exploitation program is focused on
lower-risk development drilling opportunities. 
    

   
    TECHNICAL EXPERTISE.  Each member of senior management has over 18 years 
of industry experience, and two of the three members of senior management have
worked together for over ten years. The Company believes that its drilling
success is a direct result of the technical knowledge and experience of its
geoscience staff in effective interpretation of well log data and mapping of the
subsurface geology.
    

   
    OPERATIONAL CONTROL. The Company seeks to operate the wells in which it
owns an interest whenever possible. The Company believes that control over
operations allows it to more effectively control the costs, scope and timing of
drilling and other field operations. Alternatively, when this is not possible,
the Company attempts to only own interests in wells where it has a high degree
of confidence in the operator and because of its percentage ownership can
assert substantial influence with the operator. 
    

   
    PURSUE FOCUSED PROPERTY ACQUISITION PROGRAM. The Company seeks to acquire
producing properties and undeveloped acreage where it has identified
geologically complex multi-pay subsurface environments that are well suited to
the application of 3-D seismic technology. The Company believes that its
technical expertise and historical experience with such properties allows it to
identify opportunities for lower-risk development drilling and exploitation
activities.  
    

   
    CAPITALIZE ON LOCAL RELATIONSHIPS. The Company's 15-year presence in South
Texas has resulted in numerous favorable relationships with local landowners and
their representatives. The Company believes that its favorable relationships
with these local landowners is a key advantage in its ability to access
additional undeveloped acreage acquisition opportunities.
    

   
                    RISKS ASSOCIATED WITH COMPANY OPERATIONS
                             AND THE EXCHANGE OFFER

    The Company is substantially leveraged, has generated losses since 1994 and
historically has not generated sufficient earnings to cover fixed charges. In
addition, the Company's strategy envisions the continued acquisition of
properties in the Lobo Trend, further concentrating the Company's holdings in
one geological area. The Company's operations and financial condition are also
highly dependent upon the prices of, and demand for, natural gas, and to a
lesser extent, the price of oil, in addition to the other risks specific to the
oil and gas industry. See "Risk Factors" for a discussion of certain risks to
be considered in connection with the Company, the Exchange Offer and an
investment in the New Notes.

                               THE NOTE OFFERING

The Old Notes . . . . . . . .     The Old Notes were sold by the Company on

                                  applicable interpretations of the staff of
                                  the Commission do not permit the Company to
                                  effect the Exchange Offer, or under certain
                                  other circumstances, the Company has agreed

Use of Proceeds . . . . . . .     The net proceeds from the sale of the Old
                                  Notes were used to (i) fund the cash portion

                                  indebtedness incurred to close, the 
                                  Transactions, (ii) repay certain indebtedness,
                                  (iii) acquire a net profits interest (the "Net

                               THE EXCHANGE OFFER

    The Exchange Offer applies to $135,000,000 aggregate principal amount of
the Old Notes. The form and terms of the New Notes are identical to the form
and terms of the Old Notes except that the Old Notes were offered and sold in
reliance upon certain exemptions from registration under the Securities Act,
while the offering and sale of the New Notes in exchange for the Old Notes has
been registered under the Securities Act, with the result that the New Notes
will not bear any legends restricting their transfer. See "Description of
Notes."

The Exchange Offer  . . . . .     $1,000 principal amount of New Notes for each
                                  $1,000 principal amount of Old Notes.  As of
                                  the date hereof, Old Notes representing
                                  $135,000,000 aggregate principal amount were
                                  outstanding. The terms of the New Notes and
                                  the Old Notes are substantially identical.
                                  Based on an interpretation by the Commission's
                                  staff set forth in no-action letters issued to
                                  third parties unrelated to the Company, the
                                  Company believes that, with the exceptions
                                  discussed herein, New Notes issued pursuant to
                                  the Exchange Offer in exchange for Old Notes
                                  may be offered for resale, resold and
                                  otherwise transferred by any person receiving
                                  the New Notes, whether or not that person is
                                  the holder (other than any such holder or such
                                  other person that is an "affiliate" of the
                                  Company within the meaning of Rule 405 under
                                  the Securities Act), without compliance with
                                  the registration and prospectus delivery
                                  provisions of the Securities Act, provided
                                  that (i) the New Notes are acquired in the
                                  ordinary course of business of that holder or
                                  such other person, (ii) neither the holder nor
                                  such other person is engaging in or intends to
                                  engage in a distribution of the New Notes, and
                                  (iii) neither the holder nor such other person
                                  has an arrangement or understanding with any
                                  person to participate in the distribution of
                                  the New Notes. However, the Company has not
                                  sought, and does not intend to seek, its own
                                  no-action letter, and there can be no
                                  assurance that the Commission's staff would
                                  make a similar determination with respect to
                                  the Exchange Offer.  Each broker-dealer that
                                  receives New Notes for its own account in
                                  exchange for Old Notes, where those Old Notes
                                  were acquired by the broker-dealer as a result
                                  of its market-making activities or other
                                  trading activities, must acknowledge that it
                                  will deliver a prospectus in connection with
                                  any resale of those New Notes. See "The
                                  Exchange Offer-- Purpose and Effect" and "Plan
                                  of Distribution."

                                  is extended.

                                  Old Notes will be deemed to have waived the
                                  right to receive interest accrued thereon to

                                              existing and future Senior
                                              Indebtedness of the Company, and

                  SUMMARY HISTORICAL AND PRO FORMA FINANCIAL,
                 OPERATING AND OIL AND NATURAL GAS RESERVE DATA

   
     The following tables set forth summary financial data (i) on an historical
basis for each of the years in the three-year period ended December 31, 1997,
and on a pro forma basis for the year ended December 31, 1997, and (ii) on an
historical basis for the three month periods ended, and as of, March 31, 1997
and 1998, and on a pro forma basis for the three months ended, and as of, March
31, 1998.  The historical financial data for the year ended, December 31, 1997,
have been derived from the audited Financial Statements of the Company. The
historical financial data for the three-month periods ended March 31, 1997 and
1998 are derived from unaudited Financial Statements of the Company but include
all adjustments, consisting of normal recurring adjustments, that the Company
considers necessary for a fair presentation of its results of operations for
these periods. The results for the three months ended March 31, 1998 are not
necessarily indicative of the results for the full year. The pro forma
financial, operating and oil and natural gas reserve data are not necessarily
indicative of the operating results or financial position that would have been
achieved had the transactions to which they give pro forma effect been effective
at the date or during the period presented or of the results that may be
obtained in the future. This information should be read in conjunction with
"Selected Historical and Pro Forma Financial, Operating and Oil and Natural Gas
Reserve Information," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," the Financial Statements of the Company
and the Notes thereto, the Statements of Revenues and Direct Operating Expenses
and the Notes thereto for the Enron Properties, the Conoco Properties and the
Lobo Properties, and the Company's Unaudited Pro Forma Financial Statements and
the Notes thereto included elsewhere in this Prospectus.

(3)      EBITDA is defined as earnings (excluding gain on sale of oil and
         natural gas properties) before interest expense, income taxes,
         depreciation, depletion and amortization and exploration expense.
         EBITDA is not a measure of cash flow as determined by generally
         accepted accounting principles ("GAAP"). EBITDA should not be
         considered as an alternative to, or more meaningful than, net income
         or cash flow as determined in accordance with GAAP or as an indicator
         of a company's operating performance or liquidity. Certain items
         excluded from EBITDA are significant components in understanding and
         assessing a company's financial performance, such as a company's cost
         of capital and tax structure, as well as historic costs of depreciable
         assets, none of which are components of EBITDA. The Company's
         computation of EBITDA may not be comparable to other similarly titled
         measures of other companies. The Company believes that EBITDA is a
         widely followed measure of operating performance and may also be used
         by investors to measure the Company's ability to meet future debt
         service requirements, if any. This
    




                                      -8-

         information should be read in conjunction with the Statement of Cash
         Flows contained in the Financial Statements of the Company and the
         Notes thereto included elsewhere in this Prospectus.

   
(4)      Earnings were insufficient to cover fixed charges by (i) $2,193,000,
         $916,000 and $570,000 for the historical years ended December 31, 1995,
         December 31, 1996 and December 31, 1997, respectively, and $2,828,000
         for the pro forma year ended December 31, 1997 and (ii) $235,000 for
         the historical three month period ended March 31, 1997 and $802,000 for
         the pro forma three month period ended March 31, 1998.  For purposes of
         computing the ratio of earnings to fixed charges, earnings consist of
         earnings before income taxes plus fixed charges. Fixed charges consist
         of interest and related expenses and an estimated portion of rentals
         representing interest costs.

(5)      Pro forma to reflect the sale of the Old Notes, the application of the
         net proceeds therefrom, the exchange of the Old Notes for New Notes,
         the Transactions and the Lobo Lease, as if such transactions had
         occurred on March 31, 1998, except for Reserve Data which is as of
         December 31, 1997.

(6)      ACNTA means Adjusted Consolidated Net Tangible Assets as defined in
         the Indenture. See "Description of Notes -- Certain Definitions."

(7)      The reserve and present value data as of December 31, 1996 and 1997
         (historical and pro forma) have been prepared by Huddleston & Co.,
         Inc., independent petroleum engineers to the Company.  The reserve and
         present value data as of December 31, 1995 was prepared by Mohajir &
         Associates, Inc., independent petroleum engineers to the Company.  See
         "Risk Factors -- Uncertainty of Estimates of Reserves and Future Net
         Reserves," and "Supplemental Information about Oil and Natural Gas
         Producing Activities (Unaudited)" following the Notes to the Financial
         Statements of the Company.

(8)      PV-10 Value represents the present value of estimated future net
         revenues before income tax discounted at 10% using prices in effect at
         the end of the respective periods presented and including the effects
         of hedging activities. In accordance with applicable requirements of
         the SEC, estimates of the Company's proved reserves and future net
         revenues are made using oil and natural gas sales prices estimated to
         be in effect as of the date of such reserve estimates and are held
         constant throughout the life of the properties (except to the extent a
         contract specifically provides for escalation). The average prices used
         in calculating historical PV-10 Value as of December 31, 1997 were
         $15.91 per Bbl of oil and $2.42 per Mcf of natural gas, compared to
         average prices used as of December 31, 1996 of $23.86 per Bbl of oil
         and $2.76 per Mcf of natural gas. The average prices used in
         calculating the pro forma PV-10 Value as of December 31, 1997 were
         $13.71 per Bbl of oil and $2.46 per Mcf of natural gas. Average prices
         at April 30, 1998 were $12.34 per Bbl of oil and $2.38 per Mcf of
         natural gas.

(9)      Reflects the actual realized prices received by the Company, including
         the results of the Company's hedging activities. See "Management's
         Discussion and Analysis of Financial Condition and Results of
         Operations."

(10)     Through June 30, 1996, the Company was taxed under the provisions of
         "Subchapter S" of the Internal Revenue Code. Accordingly, no provision
         for federal income taxes was recorded for periods ending prior to 
         June 30, 1996.

                                  RISK FACTORS

    In addition to the other information contained in this Prospectus,
prospective investors should carefully consider the following risk factors
relating to the Company and the Notes before making an investment in the Notes
offered hereby.

INCURRENCE OF SUBSTANTIAL INDEBTEDNESS

   
    At March 31, 1998, on a pro forma basis, the Company would have had $135.0
million of Indebtedness outstanding (including current maturities of long-term
Indebtedness) as compared to shareholders' deficit of $3.4 million. See "Use of
Proceeds" and "Capitalization." The Indenture limits the amounts of borrowings
under bank facilities, including borrowings under the Company's Credit Facility
pursuant to the terms of that certain Credit Agreement dated as of May 15, 1998.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Description of Notes--Certain
Covenants--Limitation on Incurrence of Additional Indebtedness."

    This level of Indebtedness may pose substantial risks to holders of Notes,
including, but not limited to, the following: (i) the Company's ability to
obtain additional financing in the future, whether for working capital, capital
expenditures, acquisitions or other purposes, may be impaired; (ii) a portion
of the Company's cash flow from operations is required to be dedicated to the
payment of interest on its debt, thereby reducing funds available to the
Company for other purposes; (iii) the Company may not generate sufficient cash
flow to pay the principal of and interest on the Notes; (iv) the Company's
flexibility in planning for or reacting to changes in market conditions may be
limited; and (v) the Company may be more vulnerable in the event of a downturn
in its business. In addition, the Company's earnings have been insufficient to
meet its fixed charges.

    The ability of the Company to meet its debt service obligations, including
with respect to the Notes, will depend on the future operating performance and
financial results of the Company, which will be subject in part to factors
beyond the control of the Company. Further, if the Company is unsuccessful in
increasing its proved reserves, the future net revenues from existing proved
reserves may not be sufficient to pay the principal of and interest on the Notes
in accordance with their terms. There can be no assurance that the Company will
continue to generate earnings in the future sufficient to cover its fixed
charges. If the Company is unable to generate earnings in the future sufficient
to cover its fixed charges and is unable to borrow sufficient funds to cover
such charges, it may be required to refinance all or a portion of its debt or to
sell all or a portion of its assets. There can be no assurance that a
refinancing would be possible, nor can there be any assurance as to the timing
of any asset sales or the proceeds that the Company could realize therefrom. In
addition, the Credit Agreement contains certain covenants by the Company,
including (i) limitations on additional indebtedness and on guaranties by the
Company except as permitted under the Credit Agreement, (ii) limitations on
additional investments except those permitted under the Credit Agreement and
(iii) restrictions on dividends or distributions on or repurchases or
redemptions of capital stock by the Company, except for those involving
repurchases of MHI capital stock which may not exceed $500,000 in any fiscal
year. In addition, the Credit Agreement requires the Company to maintain and
comply with certain financial covenants and ratios, including a minimum interest
coverage ratio, a minimum current ratio and a covenant requiring that the
Company's general and administrative expenses may not exceed 12.5% of the
Company's gross revenues in any calendar year. See "--Restrictions Imposed by
Lenders," "--Future Need for and Availability of Capital" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Financing Arrangements."
    

EFFECTIVE SUBORDINATION OF THE NOTES

   
    The Notes are senior unsecured obligations of the Company and rank in parity
with all existing and future Senior Indebtedness of the Company, including any
indebtedness incurred under the Credit Facility, and senior in right of payment
to all future Subordinated Indebtedness of the Company. Holders of secured
Indebtedness of the Company and its Subsidiaries, including under the Credit
Facility, will have claims with respect to assets constituting collateral for
such Indebtedness that are prior to the claims of the Holders of the Notes. In
the event of a default on the Notes, or a bankruptcy, liquidation or
reorganization of the Company and its Subsidiaries, such assets will be
available to satisfy obligations with respect to the indebtedness secured
thereby before any payment therefrom could be made on the Notes.  Accordingly,
the Notes will be effectively subordinated to claims of secured creditors of the
Company and its Subsidiaries to the extent of such pledged collateral. As of
December 31, 1997, on a pro forma basis, the Company would have had no secured
Indebtedness and no other Indebtedness other than the Notes. There is currently
no Indebtedness of the Company which would constitute Subordinated Indebtedness.
See "Description of Notes--Ranking."
    

RESTRICTIONS IMPOSED BY LENDERS

   
    The Indenture and the Credit Agreement governing the terms of the Credit
Facility impose significant operating and financial restrictions on the Company.
Such restrictions will affect, and in many respects significantly limit or
prohibit, among other things, the ability of the Company to incur additional
indebtedness, make certain capital expenditures, pay dividends, repay or
repurchase indebtedness prior to its stated maturity or engage in mergers or
acquisitions. These restrictions could also limit the ability of the Company to
effect future financings, make needed capital expenditures, withstand a future
downturn in the Company's business or the economy in general, or otherwise
conduct necessary corporate activities. A failure by the Company to comply with
these restrictions could lead to a default under the terms of such indebtedness
and the Notes. In the event of default, the holders of such indebtedness could
elect to
    





                                      -11-
<PAGE>   16
   
declare all of the funds borrowed pursuant thereto to be due and payable
together with accrued and unpaid interest. In such event, there can be no
assurance that the Company would be able to make such payments or borrow
sufficient funds from alternative sources to make any such payment. Even if
additional financing could be obtained, there can be no assurance that it would
be on terms that are favorable or acceptable to the Company. In addition, the
Company's indebtedness under the Credit Facility is secured by a substantial
portion of the assets and properties of the Company. The pledge of such
collateral to the Company's secured lenders could impair the Company's ability
to obtain additional financing on favorable terms. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and "--Financing Arrangements."
    

RISKS ASSOCIATED WITH INCREASE IN SCOPE OF OPERATIONS

    The increased scope of operations of the Company resulting from the
Transactions and the Lobo Lease presents challenges to the Company due to the
additional time and resources required to manage these newly acquired properties
and interests. Neither the members of management nor the Board of Directors
individually have had experience in integrating acquisitions or lease
transactions of the size and scope of the Transactions and the Lobo Lease.
Accordingly, there can be no assurance that the process of absorbing and
integrating the interests in the properties acquired in the Transactions and
subject to the Lobo Lease can be effectively managed. In addition, the continued
growth and expansion of the Company will depend, among other factors, on the
ability to recruit and retain skilled and experienced management and technical
personnel. There can be no assurance that the Company will be successful in such
efforts.

    The development of the Company's business and its participation in an
increasingly larger number of projects have required and will continue to
require substantial expenditures. The Company's future financial results will
depend primarily on its ability to economically locate and produce hydrocarbons
in commercial quantities and on the market prices of oil and natural gas. There
can be no assurance that the Company will achieve or sustain profitability or
positive cash flows from operating activities in the future. See "--Future Need
for and Availability of Capital," "Selected Historical and Pro Forma Financial,
Operating and Oil and Natural Gas Reserve Information," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business and Properties--Oil and Natural Gas Reserves."

FUTURE NEED FOR AND AVAILABILITY OF CAPITAL

   
    Although the Company has an initial borrowing capacity of up to $30 million
under the Credit Facility, the Company anticipates that it will require
additional financing to effect future property acquisitions and continue its
exploration and development programs. The Company or MHI may seek funds through
the sale of debt or equity securities, which could significantly dilute the
ownership of the Company's or MHI's existing shareholders. In addition, if
necessary (and permitted under the terms of the Indenture), the Company or MHI
may seek funds from project financing, strategic alliances or other sources, all
of which may dilute the interest of the Company in the specific project
financed. The Company's ability to access additional capital is dependent upon,
in part, the financial strength of the capital markets at such time. There can
be no assurance that such additional financing can be obtained or, if so,
obtained on terms acceptable to the Company.
    

    Future cash flows and the availability of credit are subject to a number of
variables, such as the level of production from existing wells, prices of oil
and natural gas and the Company's success in locating and producing new
reserves. If revenues were to decrease as a result of lower oil and natural gas
prices, decreased production or otherwise, the Company could have limited
ability to replace its reserves or to maintain production at current levels,
resulting in a decrease in production and revenues over time. The Company has
budgeted approximately $24.9 million for capital expenditures in 1998,
exclusive of acquisitions. The Company expects to use cash flow from
operations, cash balances and borrowings under the Credit Facility to fund
these expenditures. If the Company's cash flow from operations and availability
under the Credit Facility are not sufficient to satisfy its capital expenditure
requirements, there can be no assurance that additional debt or equity
financing will be available. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."

POSSIBLE LIMITATIONS ON ENFORCEABILITY OF SUBSIDIARY GUARANTEES

    Pursuant to the provisions of the Indenture, the Company's obligations
under the Notes will be guaranteed on a senior unsecured basis by any future
Subsidiary Guarantors. The Company currently has no subsidiaries. The
obligations of any Subsidiary Guarantor under its Subsidiary Guarantee may be
subject to review under applicable fraudulent conveyance statutes in the event
of the bankruptcy or other financial difficulty of any such Subsidiary
Guarantor. Under such laws, if a court in a lawsuit by an unpaid creditor or
representative of creditors of any such person, such as a trustee in bankruptcy
of any such person as debtor in possession, were to find that at the time such
person incurred its obligations under its guarantee, it (i) received less than
fair consideration or reasonably equivalent





                                      -12-
<PAGE>   17
value therefor, and (ii) either (a) was insolvent, (b) was rendered insolvent
by such guarantee, (c) was engaged in a business or transaction for which its
remaining assets constituted unreasonably small capital or (d) intended to
incur or believed that it would incur debts beyond its ability to pay such
debts as they matured, such court could void such obligations under its
guarantee and direct the return of any amounts paid with respect thereto.
Moreover, regardless of the factors identified in the foregoing clauses (i) and
(ii), a court could take such action if it found that the guarantee was entered
into with actual intent to hinder, delay or defraud creditors. The measure of
insolvency for purposes of the foregoing will vary depending on the law of the
jurisdiction being applied. Generally, however, an entity would be considered
insolvent if the sum of its debts (including contingent or unliquidated debts)
is greater than all of its property at a fair valuation or if the present fair
salable value of its assets is less than the amount that would be required to
pay its probable liability on its existing debts as they become absolute and
mature. There can be no assurance that, after providing for all prior claims,
if any, there would be sufficient assets to satisfy the claims of the holders
of the Notes relating to any voided portion of such Subsidiary Guarantees.

LIMITATIONS ON REPURCHASES OF NOTES UPON A CHANGE OF CONTROL AND CERTAIN OTHER
EVENTS

    Upon the occurrence of a Change of Control, the Company will be required to
offer to repurchase all Notes then outstanding at a purchase price equal to
101% of the principal amount of the Notes, together with accrued and unpaid
interest and Liquidated Damages, if any, to the date of repurchase. In the
event of certain asset dispositions, the Company will be required under certain
circumstances to use the Excess Proceeds to offer to repurchase the Notes (and
other Senior Indebtedness for which an offer to repurchase is required to be
concurrently made) having an aggregate principal amount equal to the Excess
Proceeds at a purchase price equal to 100% of the principal amount of the
Notes, together with accrued and unpaid interest and Liquidated Damages, if
any, to the date of repurchase (a "Net Proceeds Offer"). If a Change of Control
were to occur, the Company may not have the financial resources to repay all of
the Notes and the other indebtedness that might become payable upon the
occurrence of such Change of Control.

    The events that constitute a Change of Control or require a Net Proceeds
Offer under the Indenture may also be events of default under other
indebtedness of the Company (including the Credit Facility). Such events may
permit the lenders under such debt instruments to accelerate the debt and, if
the debt is not paid, to enforce security interests on, or commence litigation
that could ultimately result in a sale of, substantially all of the assets of
the Company, thereby limiting the Company's ability to raise cash to repurchase
the Notes and reducing the practical benefits of the offer to repurchase
provisions to the holders of the Notes. If the Company fails timely to make an
offer to repurchase or to consummate the repurchase of the Notes, such failure
will constitute an Event of Default under the Indenture.  There can be no
assurance that the Company will have sufficient funds available at the time of
any Change of Control or Net Proceeds Offer to make any debt payment (including
repurchases of Notes) as described above. See "Description of Notes--Change of
Control" and "Description of Notes--Certain Covenants--Limitation on Sale of
Assets."

VOLATILITY OF NATURAL GAS AND OIL PRICES

    The revenues generated by the Company's operations are highly dependent
upon the prices of, and demand for, natural gas and, to a lesser extent, the
price of oil. Historically, the prices of oil and natural gas have been
volatile and are likely to continue to be volatile in the future and are
dependent upon numerous factors such as weather, domestic and foreign political
and economic conditions, the overall level of international and domestic demand
for oil and natural gas, domestic and international regulatory developments,
domestic and international severance and excise taxes, competition from other
sources of energy and the availability of pipeline capacity. The Company is
affected more by fluctuations in natural gas prices than oil prices, because
the majority of its production is natural gas. The volatile nature of the
energy markets and the unpredictability of actions of OPEC members make it
impossible to predict future prices of natural gas and oil with any certainty.
Prices of natural gas and oil are subject to wide fluctuations in response to
relatively minor changes in circumstances, and there can be no assurance that
future prolonged decreases in such prices will not occur. All of these factors
are beyond the control of the Company. Any significant decline in natural gas
and oil prices would have a material adverse effect on the Company's results of
operations and financial condition, its ability to fund operations and capital
expenditures, the book value of its natural gas and oil properties and its
ability to meet its debt service requirements. Although the Company may enter
into hedging arrangements from time to time to reduce its exposure to price
risks in the sale of its natural gas and oil, substantially all of the
Company's production will remain subject to natural gas and oil price
fluctuations. See "--Risk of Hedging Activities."

DEPENDENCE ON DISTRIBUTION AND PROCESSING SYSTEMS

    The marketability of the Company's natural gas and oil production depends
upon the availability and capacity of natural gas gathering systems, pipelines
and processing facilities which are not owned by the Company. The





                                      -13-
<PAGE>   18
unavailability or lack of capacity thereof could result in the shut-in of
producing wells or the delay or discontinuance of development plans for
properties. Moreover, substantially all of the Company's properties rely on the
same gathering systems, transportation lines and processing plants. In
addition, federal and state regulation of oil and natural gas production and
transportation, general economic conditions and changes in supply and demand
could adversely affect the Company's ability to produce and market its natural
gas and oil on a profitable basis. Any significant change in the Company's
ability to market its production could have a material adverse effect on the
Company's financial condition and results of operations.

CONCENTRATION OF PRODUCING PROPERTIES

    The Company's production of natural gas and oil is concentrated within an
approximate 120 square mile area in the Lobo Trend. Any impairment or material
reduction in the expected size of the reserves attributable to the Company's
wells, any material harm to the producing reservoirs from which these wells
produce or any significant governmental regulation with respect to any of these
wells, including curtailment of production or interruption of transportation of
production, could have a material adverse effect on the Company's financial
condition and results of operations.

RISK OF HEDGING ACTIVITIES

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

    Although the Company's former hedging contracts in effect were terminated
at the closing of the sale of the Old Notes, the Company has since entered into
additional hedging contracts.  Historically, 86% and 36% of the Company's
natural gas production was hedged in 1997 and 1996, respectively. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Hedging Activities."

DRILLING RISKS

    The Company's revenues, operating results and future rate of growth will be
dependent upon the success of its drilling program, which will be funded in
part with the proceeds from the sale of the Old Notes. Oil and natural gas
drilling involves numerous risks, including the risk that no commercially
productive oil or natural gas reservoirs will be encountered. The timing and
cost of drilling, completing and operating wells is often uncertain, and
drilling operations may be curtailed, delayed or canceled as a result of a
variety of factors, including unexpected drilling conditions, pressure or
irregularities in formations, equipment failures or accidents, adverse weather
conditions, compliance with governmental requirements and shortages or delays
in the availability of drilling rigs and the delivery of equipment. Oil and
natural gas drilling remains a speculative activity notwithstanding the
Company's use of 3-D seismic data. Even when fully utilized and properly
interpreted, 3-D seismic data and other advanced technologies only assist
geoscientists in identifying subsurface structures and do not enable the
interpreter to know whether hydrocarbons are in fact present in such
structures. In addition, the use of 3-D seismic data and other advanced
technologies requires greater predrilling expenditures than traditional
drilling strategies and the Company could incur losses as a result of such
expenditures. Furthermore, completion of a well does not assure a profit on the
investment or a recovery of any portion of drilling, completion or operating
costs.





                                      -14-
<PAGE>   19
    Unsuccessful drilling activities could have a material adverse effect on
the Company's results of operations and financial condition. There can be no
assurance that the Company's overall drilling success rate or its drilling
success rate within a particular project area will not decline. The Company may
choose not to acquire option and lease rights prior to acquiring seismic data
and, in many cases, the Company may identify a prospect or drilling location
before seeking option or lease rights in the prospect or location. Although the
Company has identified or budgeted for numerous drilling prospects, there can
be no assurance that such prospects will ever be leased or drilled (or drilled
within the scheduled or budgeted time frame) or that oil or natural gas will be
produced from any such prospects or any other prospects. In addition, prospects
may initially be identified through a number of methods, some of which do not
include interpretation of 3-D or other seismic data. Actual drilling and
results are likely to vary from such statistical results and such variance may
be material. Similarly, the Company's drilling schedule may vary from its
capital budget because of future uncertainties, including those described
above. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

ABILITY AND NEED TO REPLACE RESERVES

    The Company's future success depends upon its ability to find, develop or
acquire additional oil and natural gas reserves that are economically
recoverable. Unless the Company successfully replaces the reserves that it
produces through successful development, exploration or acquisition, the
Company's proved reserves will decline. Further, substantially all of the
Company's estimated proved reserves at December 31, 1997 were located in the
Lobo Trend, where wells are characterized by high initial production followed
by rapid initial decline rates and a relative flattening of production
thereafter. Additionally, approximately 49% of the PV-10 Value of the Company's
total estimated proved reserves at December 31, 1997 was attributable to
undeveloped reserves (63% on a pro forma basis). Recovery of such reserves will
require significant capital expenditures and successful drilling operations,
and there can be no certainty regarding the results of developing these
reserves. The Company's business strategy is to add reserves by pursuing an
active development drilling program on its properties (including the properties
acquired in the Transactions) and on additional properties that it may acquire
in the future. There can be no assurance that the Company will drill the number
of wells currently projected or that the production from these new wells will
be sufficient to replace production from existing wells during such period. To
the extent the Company is unsuccessful in replacing or expanding its estimated
proved reserves, the Company may be unable to pay the principal of and interest
on the Notes in accordance with their terms, or otherwise to satisfy certain of
its covenants contained in the Indenture. See "Description of Notes--Certain
Covenants."

UNCERTAINTY OF ESTIMATES OF RESERVES AND FUTURE NET REVENUES

    The proved developed and undeveloped oil and natural gas reserve data
presented in this Prospectus are estimates based on reserve reports prepared by
independent petroleum engineers, as well as internally generated reports by the
Company. The estimation of reserves requires substantial judgment on the part
of the petroleum engineers, resulting in imprecise determinations, particularly
with respect to new discoveries. Estimates of economically recoverable oil and
natural gas reserves and of future net revenues necessarily depend upon a
number of variable factors and assumptions, such as assumed production, which
is based in part on an assessment of historical production from the area
compared with production from other producing areas, the assumed effects of
regulations by governmental agencies and assumptions concerning future oil and
natural gas prices, future operating costs, severance and excise taxes, capital
expenditures and workover and remedial costs, all of which may in fact vary
considerably from actual results. Estimates of reserves and of future net
revenues prepared by different petroleum engineers may vary substantially,
depending, in part, on the assumptions made (including assumptions required by
the SEC), as to oil and natural gas prices, drilling, workover, remedial and
operating expenses, capital expenditures, severance and ad valorem taxes and
availability of funds, and may be subject to material adjustment. Estimates of
proved undeveloped reserve quantities, which comprise 55% of the Company's
reserves as of December 31, 1997 (71% on a pro forma basis), are, by their
nature, much less certain than proved developed reserves. The accuracy of any
reserve estimate depends on the quality of available data as well as
engineering and geological interpretation and judgment. Results of drilling,
testing and production or price changes subsequent to the date of the estimate
may result in changes to such estimates. Any significant variance in the
assumptions could materially affect estimates of economically recoverable
quantities of oil and natural gas attributable to any particular group of
properties, classifications of such reserves based on risk of recovery and
estimates of the future net revenues expected therefrom. The estimates of
future net revenues contained in this Prospectus reflect oil and natural gas
prices and production costs as of the date of estimation, without escalation,
except where changes in prices were fixed under existing contracts. There can
be no assurance that such prices will be realized, estimated production volumes
will be produced or proved undeveloped reserves will be developed during the
period specified in such reports. Either inaccuracies in estimates of proved
undeveloped reserves or the inability to fund development could result in
substantially reduced reserves. In addition, the timing of receipt of estimated
future net revenues from proved undeveloped reserves will be dependent upon the
timing and implementation of drilling and development activities estimated by
the Company for purposes of the reserve report. See "Business and
Properties--Oil and Natural Gas Reserves." The estimated reserves and future
net





                                      -15-
<PAGE>   20
revenues may be subject to material downward or upward revision based upon
production history, results of future development, prevailing oil and natural
gas prices and other factors. A material decrease in estimated reserves or
future net revenues could have a material adverse effect on the Company's
financial condition and results of operations.

    In addition, the PV-10 Value of the Company's proved oil and natural gas
reserves does not necessarily represent the current or fair market value of
such proved reserves, and the 10% discount rate required by the SEC may not
reflect current interest rates, the Company's cost of capital or any risks
associated with the development and production of the Company's proved oil and
natural gas reserves. In accordance with applicable SEC requirements, proved
reserves and the future net revenues from which PV-10 Value is derived are
estimated using prices and costs at the date of the estimate held constant
throughout the life of the properties (except to the extent a contract
specifically provides otherwise).  The Company emphasizes with respect to such
estimates that the discounted future net cash flows should not be construed as
representative of the fair market value of the proved oil and natural gas
properties belonging to the Company, because discounted future net cash flows
are based upon projected cash flows that do not provide for changes in oil and
natural gas prices or for escalation of expenses and capital costs. The
meaningfulness of such estimates is highly dependent upon the accuracy of the
assumptions upon which they were based. Actual results may differ materially
from the results estimated. Holders and prospective purchasers of the Notes are
cautioned not to place undue reliance on the reserve data included in this
Prospectus. The estimated future net revenues attributable to the Company's
proved oil and natural gas reserves, on a pro forma basis, are based on prices
in effect at December 31, 1997 ($2.46 per Mcf of natural gas and $13.71 per Bbl
of oil), which have decreased since December 31, 1997 and may be materially
different than actual future prices. See "Business and Properties--Oil and
Natural Gas Reserves."

SHORTAGES OF DRILLING RIGS, EQUIPMENT, SUPPLIES AND PERSONNEL

    In the past, there have been periods where general shortages of drilling
rigs, equipment and supplies have occurred.  Shortages of drilling rigs,
equipment or supplies could delay and adversely affect the Company's
exploration and development operations, which could have a material adverse
effect on its business, financial condition and results of operations.

    The demand for, and wage rates of, qualified rig crews have begun to rise
in the drilling industry in response to the increasing number of active
drilling rigs in service. Shortages of qualified rig crews have in the past
occurred in the industry in times of increasing demand for drilling services.
If the number of active drilling rigs continues to increase, the oil and
natural gas industry may experience shortages of qualified personnel to operate
drilling rigs, which could delay the Company's drilling operations and
adversely affect the Company's business, financial condition and results of
operations.

RISKS ASSOCIATED WITH ACQUISITIONS

    The successful acquisition of producing properties requires an assessment
of recoverable reserves, future oil and natural gas prices, operating costs,
potential environmental and other liabilities and other factors. Such
assessments are necessarily inexact. In connection with its assessment of a
potential acquisition, the Company performs a review of the subject properties
that it believes to be generally consistent with industry practices, including
examination of contingencies associated with the properties. Such a review,
however, will not reveal all existing or potential problems nor will it permit
a buyer to become sufficiently familiar with the properties to fully assess the
deficiencies and capabilities of such properties. Inspections may not always be
performed on every well, and structural and environmental problems are not
necessarily observable even when an inspection is undertaken. Even when
problems are identified, the seller may be unwilling or unable to provide
effective contractual protection against all or part of such problems.  There
can be no assurance that the Company will be able to identify attractive
acquisition opportunities, obtain financing for acquisitions on satisfactory
terms or successfully acquire identified targets. Furthermore, there can be no
assurance that competition for acquisition opportunities in these industries
will not escalate, thereby increasing the cost to the Company of making further
acquisitions or causing the Company to refrain from making further
acquisitions. In addition, there can be no assurance that any acquisition of
property interests by the Company will be successful and, if unsuccessful, that
such failure will not have a material adverse effect on the Company's future
results of operations and financial condition.

OPERATIONAL HAZARDS AND UNINSURED RISKS

    Oil and natural gas drilling activities are subject to numerous risks, many
of which are beyond the Company's control, including the risk that no
commercially productive oil or natural gas reservoirs will be encountered. The
cost of drilling, completing and operating wells is often uncertain, and
drilling operations may be curtailed, delayed or canceled as a result of a
variety of factors, including unexpected drilling conditions, pressure
irregularities in





                                      -16-
<PAGE>   21
formations, equipment failures or accidents, adverse weather conditions, title
problems and shortages or delays in the delivery of equipment. The Company's
future drilling activities may not be successful and, if unsuccessful, such
failure will have an adverse effect on future results of operations and
financial condition.

    In addition, oil and natural gas operations involve hazards such as fire,
explosion, blowout, pipe failure, casing collapse, unusual or unexpected
formation pressures and environmental hazards such as oil spills, gas leaks,
ruptures and discharges of toxic gases, the occurrence of any one of which
could result in substantial losses to the Company due to injury or loss of
life, severe damage to or destruction of property, natural resources and
equipment, pollution or other environmental damage, cleanup responsibilities,
regulatory investigation and penalties and suspension of operations. Although
the Company maintains insurance against certain risks that it believes are
customarily insured against by companies in the industry of comparable size and
scope of operations, such insurance does not cover all of the risks and hazards
involved in oil and natural gas exploration, drilling and production because
insurance is unavailable at economic rates, there are limitations in the
Company's insurance policies or for other reasons. Even if coverage does exist,
it may not be sufficient to pay the full amount of liabilities incurred, and
there can be no assurance that such insurance will continue to be available on
terms acceptable to the Company. Any uninsured loss could have a material
adverse effect on the Company's financial condition and results of operations.
See "--Regulatory and Environmental Risks."

COMPETITION IN THE OIL AND NATURAL GAS INDUSTRY

    The Company encounters competition from other oil and natural gas companies
in all areas of its operations, including the acquisition of exploratory
prospects and proven properties. Properties within the Lobo Trend are
characterized by large tracts (typically 5,000 to 50,000 acres) that have been
owned by the same families for generations. Securing leases or necessary
permits and approvals for 3-D seismic shoots depends heavily on developing and
maintaining favorable relationships with the surface owners. The Company's
competitors, particularly in the Lobo Trend, include major integrated oil and
natural gas companies and independent oil and natural gas companies,
individuals and drilling and income programs. Most of its competitors are
large, well-established companies with substantially larger operating staffs
and significantly greater capital resources than those of the Company and
which, in many instances, have been engaged in the oil and natural gas business
for a much longer time than the Company. Such companies may be able to pay more
for exploratory prospects and productive oil and natural gas properties and may
be able to define, evaluate, bid for and purchase a greater number of
properties and prospects than could the Company, given its limited financial
and human resources. There can be no assurance that the Company will be able to
secure the necessary financing or industry partners or evaluate and select
suitable properties and consummate transactions in this highly competitive
environment. See "Business and Properties--Competition."

PROPERTY IMPAIRMENT CHARGES

    Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires
that long-lived assets held and used by an entity be reviewed for impairment
whenever events or changes indicate that the net book value of an asset may not
be recoverable. The net book value of an asset is reduced to fair value if the
sum of expected undiscounted future net cash flows from the use of the asset is
less than the net book value of the asset.  Under SFAS No. 121 the Company
evaluates impairment of oil and natural gas properties on a field basis.
Applying SFAS No. 121, the Company recognized non-cash property impairment
charges of $238,000 in 1997 and $156,000 in 1996. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Results of
Operations." Significant declines in oil or natural gas prices or downward
revisions of reserve estimates could adversely impact the Company's estimates
of future net revenues from its proved reserves and consequently could result
in future non-cash impairment charges against the Company's income.

DEPENDENCE ON KEY PERSONNEL

    The Company is dependent upon the efforts and skills of key executives of
the Company, including Glenn D. Hart, Chairman of the Board and Chief Executive
Officer, Michael G. Farmar, President and Chief Operating Officer, and Jerry F.
Holditch, Vice President-Exploration. The loss of any of these officers or
other key personnel could have a material adverse effect on the Company.
Further, as the Company grows its asset base and scope of operations as a
result of the Transactions and other future acquisitions, its future
profitability will depend upon the Company's ability to attract and retain
additional qualified personnel. See "Management."





                                      -17-
<PAGE>   22
CONTROL BY CERTAIN SHAREHOLDERS

    The Company is a wholly-owned subsidiary of MHI, which in turn is
principally owned by the management of the Company and MHI. As of the date of
this Prospectus, four of the Company's directors, three of whom are also
executive officers of the Company, beneficially owned 702,050 shares of common
stock of MHI (the "Common Stock") representing, in the aggregate, approximately
91% of the outstanding Common Stock. Such owners, should they act together,
would have sufficient voting power to (i) elect the entire Boards of Directors
of the Company and MHI, (ii) exercise control over the business, policies and
affairs of the Company and MHI and (iii) in general, determine the outcome of
any corporate transaction or other matters submitted to the stockholders for
approval such as (a) any amendment to the Company's Articles of Incorporation,
(b) the authorization of additional shares of capital stock and (c) any merger,
consolidation or sale of all or substantially all of the assets of the Company
which could prevent or cause a change of control of the Company. See "Principal
Shareholders."

REGULATORY AND ENVIRONMENTAL RISKS

    Oil and natural gas operations are subject to various federal, state and
local governmental regulations which may be changed from time to time in
response to economic or political conditions. From time to time, regulatory
agencies have imposed price controls and limitations on production in order to
conserve supplies of oil and natural gas. In addition, the production,
handling, storage, transportation and disposal of oil and natural gas,
byproducts thereof and other substances and materials produced or used in
connection with oil and natural gas operations are subject to regulation under
federal, state and local laws and regulations. See "Business and
Properties--Governmental Regulation."

   
    The Company's operations currently are located primarily in Texas. Thus, the
Company's business is subject to environmental regulation on the state level
primarily by the Railroad Commission of Texas and the Texas Natural Resource
Conservation Commission. The Railroad Commission of Texas regulations may
require on the Company to obtain permits and drilling bonds for the drilling of
wells. Additionally, the Railroad Commission of Texas regulates the spacing of
wells, plugging and abandonment of such wells and the remediation of
contamination caused by most types of exploration and production wastes. The
Railroad Commission requirements for remediation of contamination are, for the
most part, administered on a case-by-case basis. The Company expects that such
regulations will be formalized in the future and will in all likelihood become
more stringent.
    

   
    Currently, federal regulations provide that drilling fluids, produced waters
and other wastes associated with the exploration, development or production of
oil and natural gas are exempt from regulation as "hazardous waste." To the
extent that the Company's operations produce wastes that do not fall within this
exemption, the storage, handling and disposal of those wastes are regulated on
the state level by the Texas Natural Resource Conservation Commission. From time
to time, legislation has been proposed to eliminate or modify this exemption.
Should the exemption be modified or eliminated, wastes associated with oil and
natural gas exploration and production would be subject to more stringent
regulation. On the federal level, the Company's operations may be subject to
various federal statutes, including the Natural Gas Act, the Comprehensive
Environmental Response, Compensation the Liability Act, the Solid Waste Disposal
Act, as amended by the Resource Conservation and Recovery Act, the Clean Air
Act, the Federal Water Pollution Control Act and the Oil Pollution Act, as well
as by regulations promulgated pursuant to these actions.
    

   
     These regulations subject the Company to increased operating costs and
potential liability associated with the use and disposal of hazardous materials.
Although these laws and regulations have not had a material adverse effect on
the Company's financial condition or results of operations, there can be no
assurance that the Company will not be required to make material expenditures in
the future. Moreover, the Company anticipates that such laws and regulations
will become increasingly stringent in the future, which could lead to material
costs for environmental compliance and remediation by the Company.  See
"Business and Properties--Governmental Regulation."
    

    Any failure by the Company to obtain required permits for, control the use
of, or adequately restrict the discharge of hazardous substances under present
or future regulations could subject the Company to substantial liability or
could cause its operations to be suspended. Such liability or suspension of
operations could have a material adverse effect on the Company's business,
financial condition and results of operations.

LACK OF PUBLIC MARKET

    The Old Notes are designated for trading in the PORTAL market. There is no
established trading market for the New Notes. The Company does not currently
intend to list the New Notes on any securities exchange or to seek approval for
quotation through any automated quotation system. Accordingly, there can be no
assurance as to the development of any market or the liquidity of any market
that may develop for the New Notes. If such a market were to exist, no
assurance can be given as to the trading prices of the New Notes, which will
depend on many factors, including, among other things, prevailing interest
rates, the Company's operating results and the market for similar securities.
The liquidity of, and trading market for, the New Notes may be adversely
affected by general declines in the market for similar securities. Such a
decline may adversely affect such liquidity and trading markets independent of
the financial performance of, and prospects for, the Company.

ADVERSE CONSEQUENCES OF FAILURE TO EXCHANGE

    The Old Notes were sold pursuant to an exemption from the registration
requirements of the Securities Act and their transfer is subject to certain
restrictions under the Securities Act.  In general, Old Notes may not be
offered or sold unless registered under the Securities Act, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws.  Holders of Old Notes who do not exchange
their Notes for New Notes pursuant to the Exchange Offer will continue to be
subject to such restrictions on transfer of the Old Notes.  The Company
currently does not anticipate that it will register the Old Notes under the
Securities Act.  To the extent that Old Notes are tendered and accepted in the
Exchange Offer, the trading market for untendered and tendered but unaccepted
Old Notes could be adversely affected.  See "The Exchange Offer -- Consequences
of Failure to Exchange."





                                      -18-
<PAGE>   23
RISKS ASSOCIATED WITH EXCHANGE OFFER PROCEDURES

    The New Notes will be issued in exchange for Old Notes only after timely
receipt by the Exchange Agent of such Old Notes, a properly completed and duly
executed Letter of Transmittal and all other required documents.  Therefore,
holders of Old Notes desiring to tender such Old Notes in exchange for New
Notes should allow sufficient time to ensure timely delivery.  Neither the
Exchange Agent nor the Company is under any duty to give notification of
defects or irregularities with respect to tenders of Old Notes for exchange.
Old Notes that are not tendered or are tendered but not accepted will,
following consummation of the Exchange Offer, continue to be subject to the
existing restrictions upon transfer thereof.  In addition, any holder of Old
Notes who tenders in the Exchange Offer for the purpose of participating in a
distribution of the New Notes will be required to comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any resale transaction.  Each broker-dealer that receives New Notes for its own
account in exchange for Old Notes, where the Old Notes were acquired by the
broker-dealer as a result of market-making or any other trading activities,
must acknowledge that it will deliver a prospectus in connection with any
resale of such New Notes.  See "Plan of Distribution."

YEAR 2000 RISKS

   
     The Company has reviewed its computer systems and hardware to locate
potential operational problems associated with the year 2000 issue. The Company
believes that all year 2000 problems in its internal information processing
computer systems have been resolved and have not caused and will not cause
disruption of its operations, or have a material adverse effect on its financial
condition or results of operations. The Company is in the process of contacting
and receiving verification of year 2000 issue compliance from its vendors, 
purchasers, suppliers, transporters of its production and its financial service
providers. At this time, the Company does not anticipate any material disruption
in its operations as a result of any year 2000 compliance issues, but will
continue to monitor the situation with third parties.
    

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT

   
    The Old Notes were sold by the Company on April 2, 1998, in a private
placement pursuant to an exemption from registration under the Securities Act.
In connection with that private placement, the Company entered into the
Registration Rights Agreement which requires that the Company file the
registration statement of which this Prospectus is a part (the "Registration
Statement") under the Securities Act with respect to the New Notes on or prior
to 45 days after the date of issuance of the Old Notes (the "Issue Date").  The
Registration Rights Agreement further requires that, upon the effectiveness of
the Registration Statement, the Company offer to the holders of the Old Notes
the opportunity to exchange their Old Notes for a like principal amount of New
Notes, which will be issued without a restrictive legend and may be reoffered
and resold by the holder without further registration under the Securities Act.
The Company has agreed to use its reasonable best efforts to cause the
Registration Statement to be declared effective within 120 days following the
Issue Date and to consummate the Exchange Offer within 30 days after the
Registration Statement is declared effective by the Commission. If the Company
has not caused a Registration Statement to become effective by July 31, 1998 (a
"Registration Default"), the Company must pay Liquidated Damages of 0.5% per
annum of the principal amount held by each holder of the Old Notes, accruing
from the first day of the Registration Default and continuing for 180 days
thereafter.  Such Liquidated Damages increase by an additional 0.5% per annum of
principal amount of the Old Notes during each subsequent 180-day period, up to
a maximum Liquidated Damages amount of 2.0% per annum of the Old Notes. A copy
of the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement.
    


    In order to participate in the Exchange Offer, a holder must represent to
the Company, among other things, that (i) any New Notes to be received by it
will be acquired in the ordinary course of its business, (ii) if the holder is
not a broker-dealer, that it is not engaged in, and does not intend to engage
in, the distribution of the New Notes and it has no arrangement with any person
to participate in the distribution of the New Notes and (iii) it is not an
"affiliate" (as defined in Rule 405 under the Securities Act) of the Company,
or if it is an affiliate, it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable. Each
broker-dealer that receives New Notes for its own account pursuant to the
Exchange Offer should acknowledge that it acquired the Old Notes for its own
account as the result of market making activities or other trading activities.
Any holder who is unable to make the appropriate representations to the Company
will not be permitted to tender the Old Notes in the Exchange Offer and will be
required to comply with the registration and prospectus delivery requirements
of the Securities Act (or an appropriate exemption therefrom) in connection
with any sale or transfer of the Old Notes.

    Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to the Company, the Company believes
that, with the exceptions discussed herein, New Notes issued pursuant to the
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by any person receiving the New Notes, whether or not
that person is the holder (other than any such holder or such other person that
is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that (i) the New Notes are
acquired in the ordinary course of business of that holder or such other
person, (ii) neither the holder nor such other person is engaging in or intends
to engage in a distribution (within the meaning of the Securities Act) of the
New





                                      -19-
<PAGE>   24
Notes, and (iii) neither the holder nor such other person has an arrangement or
understanding with any person to participate in the distribution of the New
Notes.  See "Plan of Distribution."

CONSEQUENCES OF FAILURE TO EXCHANGE

    The Old Notes are designated for trading in the PORTAL market. To the
extent Old Notes are tendered and accepted in the Exchange Offer, the principal
amount of outstanding Old Notes will decrease with a resulting decrease in the
liquidity in the market therefor.  Following the consummation of the Exchange
Offer, holders of Old Notes who were eligible to participate in the Exchange
Offer but who did not tender their Old Notes will not be entitled to certain
rights under the Registration Rights Agreement, and such Old Notes will
continue to be subject to certain restrictions on transfer.  In general, the
Old Notes may not be offered or sold, unless registered under the Securities
Act and applicable state securities laws, except pursuant to an exemption from,
or in a transaction not subject to, the Securities Act and applicable state
securities laws. The Company does not intend to register the Old Notes under
the Securities Act and, after consummation of the Exchange Offer, will not be
obligated to do so.

TERMS OF THE EXCHANGE OFFER

    Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old Notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
the Expiration Date.  As soon as practicable after the Expiration Date, the
Company will issue $1,000 principal amount of New Notes in exchange for each
$1,000 principal amount of outstanding Old Notes accepted in the Exchange
Offer.  Holders may tender some or all of their Old Notes pursuant to the
Exchange Offer. However, Old Notes may be tendered only in integral multiples
of $1,000 in principal amount.

    The form and terms of the New Notes are identical to the form and terms of
the Old Notes except that the Old Notes were offered and sold in reliance upon
certain exemptions from registration under the Securities Act, while the
offering and sale of the New Notes in exchange for the Old Notes have been
registered under the Securities Act, with the result that the New Notes will
not bear any legends restricting their transfer. Also, holders of the New Notes
will not be entitled to certain rights under the Registration Rights Agreement.
The New Notes will evidence the same debt as the Old Notes and will be issued
pursuant to, and entitled to the benefits of, the Indenture.

    As of the date of this Prospectus, $135,000,000 aggregate principal amount
of the Old Notes was outstanding and registered in the name of Cede & Co., as
nominee for the DTC.  The Company has fixed the close of business on _______,
1998, as the record date for the Exchange Offer for purposes of determining the
persons to whom this Prospectus, together with the Letter of Transmittal, will
initially be sent.  Holders of Old Notes do not have any appraisal or
dissenters' rights under the Texas Business Corporation Act or the Indenture in
connection with the Exchange Offer. The Company intends to conduct the Exchange
Offer in accordance with the applicable requirements of the Exchange Act and
the rules and regulations of the Commission promulgated thereunder, including
Rule 14e-1 thereunder.

    The Company shall be deemed to have accepted validly tendered Old Notes
when, as, and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the New Notes from the Company.  If any tendered
Old Notes are not accepted for exchange because of an invalid tender, the
occurrence of certain other events set forth herein or otherwise, the
certificates for such unaccepted Old Notes will be returned, without expense,
to the tendering holder thereof as promptly as practicable after the Expiration
Date.

    Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than transfer taxes, in connection with the Exchange Offer. See "The
Exchange Offer--Solicitation of Tenders; Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS
   
    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
Monday, August 31, 1998, unless the Company, in its sole discretion, extends
the Exchange Offer, in which case the term "Expiration Date" shall mean the
latest date and time to which the Exchange Offer is extended. In order to
extend the Exchange Offer, the Company will notify the Exchange Agent of any
extension by oral or written notice prior to 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date. The
Company reserves the right, in its sole discretion, (i) to delay accepting any
Old Notes, to extend the Exchange Offer or, if any of the conditions set forth
under "The Exchange Offer--Conditions" shall not have been satisfied, to
terminate the Exchange Offer, by giving oral or written notice of such delay,
extension or termination to the Exchange Agent, or (ii) to amend the
    





                                      -20-
<PAGE>   25
terms of the Exchange Offer in any manner.  If the Exchange Offer is amended in
a manner determined by the Company to constitute a material change, the Company
will promptly disclose such amendment in a manner reasonably calculated to
inform the holders of the Old Notes of such amendment.  Without limiting the
manner in which the Company may choose to make public announcements of any
delay in acceptance, extension, termination or amendment of the Exchange Offer,
the Company shall have no obligation to publish, advertise, or otherwise
communicate any such public announcement, other than by making a timely release
to the Dow Jones News Service.

INTEREST ON THE NEW NOTES

    The New Notes will bear interest from April 2, 1998, the date of issuance
of the Old Notes that are tendered for exchange of the New Notes (or the most
recent interest payment date to which interest on such Old Notes has been
paid).  Accordingly, holders of Old Notes accepted for exchange will not
receive interest that is accrued but unpaid on the Old Notes at the time of
tender, but such interest will be payable on the first interest payment date
after the consummation of the Exchange Offer.  Holders of Old Notes accepted
for exchange in the Exchange Offer will be deemed to have waived the right to
receive interest accrued but unpaid thereon as of the date of exchange.
Interest on the New Notes will be payable semi-annually on April 1 and October
1 of each year, commencing October 1, 1998.

PROCEDURES FOR TENDERING

    Only a registered holder of Old Notes may tender the Old Notes in the
Exchange Offer. Except as set forth under "The Exchange Offer--Book Entry
Transfer," to tender in the Exchange Offer a holder must complete, sign and
date the Letter of Transmittal, or a copy thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver the Letter of Transmittal or copy to the Exchange Agent for receipt
prior to 5:00 p.m. on the Expiration Date. In addition, either (i) certificates
for such Old Notes must be received by the Exchange Agent along with the Letter
of Transmittal, (ii) a timely confirmation of a book-entry transfer (a
"Book-Entry Confirmation") of such Old Notes, if that procedure is available,
into the Exchange Agent's account at DTC (the "Book-Entry Transfer Facility")
pursuant to the procedure for book-entry transfer described below, must be
received by the Exchange Agent prior to the Expiration Date, or (iii) the
holder must comply with the guaranteed delivery procedures described below.  To
be tendered effectively, the Old Notes, Letter of Transmittal and other
required documents must be received by the Exchange Agent at the address set
forth under "The Exchange Offer --Exchange Agent" prior to 5:00 p.m. on the
Expiration Date.

    The tender by a holder that is not withdrawn before the Expiration Date
will constitute an agreement between that holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal.

    THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE 5:00 P.M. ON THE
EXPIRATION DATE AND PROPER INSURANCE SHOULD BE OBTAINED. NO LETTER OF
TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST
THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES, OR
NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH HOLDERS.

    Any beneficial owner whose Old Notes are registered in the name of a
broker, dealer, commercial bank, trust company, or other nominee and who wishes
to tender should contact the registered holder promptly and instruct the
registered holder to tender on the beneficial owner's behalf.  If the
beneficial owner wishes to tender on its own behalf, such owner must, prior to
completing and executing the Letter of Transmittal and delivering the owner's
Old Notes, either make appropriate arrangements to register ownership of the
Old Notes in the beneficial owner's name or obtain a properly completed bond
power from the registered holder. The transfer of registered ownership may take
considerable time.

    Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined herein)
unless the Old Notes tendered pursuant thereto are tendered (i) by a registered
holder who has not completed the box titled "Special Registration Instructions"
or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. If signatures on a Letter of Transmittal or
a notice of withdrawal, as the case may be, are required to be guaranteed, the
guarantee must be by any eligible guarantor institution that is a member of or
participant in the Securities Transfer Agents Medallion Program, the New





                                      -21-
<PAGE>   26
York Stock Exchange Medallion Signature Program or the Stock Exchange Medallion
Program (an "Eligible Institution").

    If the Letter of Transmittal is signed by a person other than the
registered holder of any Old Notes listed therein, such Old Notes must be
endorsed or accompanied by a properly completed bond power, signed by the
registered holder as that registered holder's name appears on the Old Notes
with the signature thereon guaranteed by an Eligible Institution.

    If the Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and evidence satisfactory to the
Company of their authority to so act must be submitted with the Letter of
Transmittal unless waived by the Company.

    All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Old Notes will be determined by
the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Old
Notes not properly tendered or any Old Notes the Company's acceptance of which
would, in the opinion of counsel for the Company, be unlawful. The Company also
reserves the right to waive any defects, irregularities or conditions of tender
as to particular Old Notes. The Company's interpretation of the terms and
conditions of the Exchange Offer (including the instructions in the Letter of
Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Old Notes must be cured
within such time as the Company shall determine. Although the Company intends
to notify holders of defects or irregularities with respect to tenders of Old
Notes, neither the Company, the Exchange Agent nor any other person shall incur
any liability for failure to give such notification. Tenders of Old Notes will
not be deemed to have been made until such defects or irregularities have been
cured or waived. Any Old Notes received by the Exchange Agent that the Company
determines are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.

    In addition, the Company reserves the right in its sole discretion to
purchase or make offers for any Old Notes that remain outstanding after the
Expiration Date or, as set forth under "The Exchange Offer--Conditions," to
terminate the Exchange Offer and, to the extent permitted by applicable law,
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the
terms of the Exchange Offer.

    By tendering, each holder will represent to the Company that, among other
things, (i) the New Notes acquired pursuant to the Exchange Offer are being
acquired in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the holder, (ii) if it is not a
broker-dealer, neither the holder nor any such other person is engaging in or
intends to engage in a distribution of such New Notes nor has an arrangement or
understanding with any person to participate in the distribution of such New
Notes, and (iii) neither the holder nor any such other person is an "affiliate"
(as defined under Rule 405 of the Securities Act) of the Company.  Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes, where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities (other than Old Notes
acquired directly from the Company), may participate in the Exchange Offer but
may be deemed an "underwriter" under the Securities Act and, therefore, must
acknowledge in the Letter of Transmittal that it will deliver a prospectus in
connection with any resale of such New Notes. The Letter of Transmittal states
that, by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. See "Plan of Distribution."

    In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-Entry
Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal (or, with respect to the DTC and its participants, electronic
instructions in which the tendering holder acknowledges its receipt of and
agreement to be bound by the Letter of Transmittal), and all other required
documents. If any tendered Old Notes are submitted for a greater principal
amount than the holder desires to exchange, such unaccepted or non-exchanged
Old Notes will be returned without expense to the tendering holder thereof (or,
in the case of Old Notes tendered by book-entry transfer into the Exchange
Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry
transfer procedures described below, such non-exchanged Old Notes will be
credited to an account maintained with such Book-Entry Transfer Facility) as
promptly as practicable after the expiration of the Exchange Offer.





                                      -22-
<PAGE>   27
BOOK-ENTRY TRANSFER

    The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility system may make book-entry delivery of Old Notes being tendered by
causing the Book-Entry Transfer Facility to transfer such Old Notes into the
Exchange Agent's account at the Book-Entry Transfer Facility in accordance with
such Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Old Notes may be effected through book-entry transfer at the
Book-Entry Transfer Facility, the Letter of Transmittal or copy thereof, with
any required signature guarantees and any other required documents, must, in
any case other than as set forth in the following paragraph, be transmitted to
and received by the Exchange Agent at the address set forth under "The Exchange
Offer--Exchange Agent" on or prior to the Expiration Date or the guaranteed
delivery procedures described below must be complied with.

    The DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through the DTC.  To accept the Exchange Offer
through ATOP, participants in the DTC must send electronic instructions to the
DTC through the DTC's communication system in lieu of sending a signed, hard
copy Letter of Transmittal. The DTC is obligated to communicate those
electronic instructions to the Exchange Agent. To tender Old Notes through
ATOP, the electronic instructions sent to the DTC and transmitted by the DTC to
the Exchange Agent must contain the character by which the participant
acknowledges its receipt of and agrees to be bound by the Letter of
Transmittal.

GUARANTEED DELIVERY PROCEDURES

    If a registered holder of the Old Notes desires to tender such Old Notes
and the Old Notes are not immediately available, or time will not permit such
holder's Old Notes or other required documents to reach the Exchange Agent
before the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is made
through an Eligible Institution, (ii) prior to the Expiration Date, the
Exchange Agent received from such Eligible Institution a properly completed and
duly executed Letter of Transmittal (or a facsimile thereof) and Notice of
Guaranteed Delivery, substantially in the form provided by the Company (by
telegram, telex, facsimile transmission, mail or hand delivery), setting forth
the name and address of the holder of Old Notes and the amount of Old Notes
tendered, stating that the tender is being made thereby and guaranteeing that
within three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and any other documents required by the
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent, and (iii) the certificates for all physically tendered Old
Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case
may be, and all other documents required by the Letter of Transmittal, are
received by the Exchange Agent within three NYSE trading days after the date of
execution of the Notice of Guaranteed Delivery.  Upon request to the Exchange
Agent, a Notice of Guaranteed Delivery will be sent to holders who wish to
tender their Old Notes according to the guaranteed delivery procedures set
forth above.

WITHDRAWAL RIGHTS

    Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date.

    For a withdrawal of a tender of Old Notes to be effective, a written or
(for DTC participants only) electronic ATOP transmission notice of withdrawal
must be received by the Exchange Agent at its address set forth herein prior to
5:00 p.m., New York City time, on the Expiration Date. Any such notice of
withdrawal must (i) specify the name of the person having deposited the Old
Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be
withdrawn (including the certificate number or numbers and principal amount of
such Old Notes), (iii) be signed by the holder in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the Old
Notes register the transfer of such Old Notes into the name of the person
withdrawing the tender, and (iv) specify the name in which any such Old Notes
are to be registered, if different from that of the Depositor. All questions as
to the validity, form and eligibility (including time of receipt) of such
notices will be determined by the Company, in its sole discretion, whose
determination shall be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for exchange for
purposes of the Exchange Offer. Any Old Notes which have been tendered for
exchange but which are not exchanged for any reason will be returned to the
holder thereof without cost to such holder as soon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. Properly
withdrawn Old Notes may be retendered by





                                      -23-
<PAGE>   28
following one of the procedures described under "The Exchange Offer--Procedures
for Tendering" at any time on or prior to the Expiration Date.

CONDITIONS

    Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange New Notes for, any Old Notes,
and may terminate the Exchange Offer as provided herein before the acceptance
of such Old Notes, if (i) the Exchange Offer shall violate applicable law or
any applicable  interpretation of the staff of the Commission, (ii) any action
or proceeding is instituted or threatened in any court or by any governmental
agency that might materially impair the ability of the Company to proceed with
the Exchange Offer or any material adverse development has occurred in any
existing action or proceeding with respect to the Company, or (iii) any
governmental approval has not been obtained, which approval the Company shall
deem necessary for the consummation of the Exchange Offer.  If the Company
determines in its sole discretion that any of the conditions are not satisfied,
the Company may (i) refuse to accept any Old Notes and return all tendered Old
Notes to the tendering holders (or, in the case of Old Notes tendered by
book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer
Facility pursuant to the book-entry transfer procedures described above, such
Old Notes will be credited to an account maintained with such Book-Entry
Transfer Facility), (ii) extend the Exchange Offer and retain all Old Notes
tendered prior to the expiration of the Exchange Offer, subject, however, to the
rights of holders to withdraw such Old Notes (see "--Withdrawal Rights") or
(iii) waive such unsatisfied conditions with respect to the Exchange Offer and
accept all properly tendered Old Notes which have not been withdrawn. If such
waiver constitutes a material change to the Exchange Offer, the Company will
promptly disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and the Company will extend the Exchange
Offer for a period of five to ten business days, depending upon the significance
of the waiver and the manner of disclosure to the registered holders, if the
Exchange Offer would otherwise expire during such five-to-ten-business-day
period.

SOLICITATIONS OF TENDERS; FEES AND EXPENSES

    The expenses of soliciting acceptances to the Exchange Offer will be borne
by the Company.  The principal solicitation is being made by mail; however,
additional solicitations may be made in person or by telephone by officers and
employees of the Company.  The Company has not retained any dealer-manager or
similar agent in connection with the Exchange Offer and will not make any
payments to brokers, dealers or others soliciting acceptances of the Exchange
Offer. The Company, however, will pay the Exchange Agent reasonable and
customary fees for its services and will reimburse it for its reasonable
out-of-pocket expenses in connection therewith.  Other cash expenses to be
incurred in connection with the Exchange Offer and to be paid by the Company
include registration, accounting and legal fees and printing costs, among
others.

ACCOUNTING TREATMENT

    For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer.  The expenses of the Exchange Offer will be
amortized over the term of the New Notes.

TRANSFER TAXES

    Holders who tender their Old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith, except that holders who
instruct the Company to register New Notes in the name of, or request that Old
Notes not tendered or not accepted in the Exchange Offer be returned to, a
person other than the registered tendering holder will be responsible for the
payment of any applicable transfer tax thereon.

                                USE OF PROCEEDS

    There will be no cash proceeds to the Company from the Exchange Offer.

     The net proceeds to the Company from the sale of the Old Notes (after
deduction of discount, fees and other expenses associated with such sale) were
approximately $127.8 million. Approximately $45.8 million of the net proceeds
were used to repay short-term acquisition indebtedness incurred by the Company
to pay the cash portion of the purchase price of the Enron Acquisition. This
short-term indebtedness was repaid on April 2, 1998 and bore interest at the
rate of 8% per annum. (The cash portion of the purchase price for the Enron
Acquisition as provided in the purchase and sale agreement was $48.5 million,
but was reduced to $45.8 million as a result of certain closing adjustments,
including amounts of net production accrued to the seller's account since
January 1, 1998, the effective date of the Enron Acquisition.) Approximately
$22.5 million of the net proceeds were used to fund the Conoco Acquisition (the
purchase price of the Conoco Acquisition as provided in the purchase and sale
agreement was $23.3 million, but was reduced to $22.5 million as a result of
similar closing adjustments). Approximately $39.0 million of the net proceeds
were used to (i) repay indebtedness under a credit facility with Triassic Energy
Partners, L.P. (the "T.E.P. Financing") incurred in connection with the
acquisition by the Company in August 1996 of interests in approximately 21,000
developed and undeveloped acres in the Lobo Trend (the "Lobo Properties") for
approximately $15.3 million net to the Company (the "1996 Lobo Acquisition") and
(ii) acquire a Net Profits Interest from an affiliate of Triassic Energy
Partners, L.P. Interest on the borrowings under the T.E.P. Financing accrued at
a weighted average stated interest rate of approximately 12.8% per annum as of
March 27, 1998.  On April 20, 1998, the Company entered into the Lobo Lease with
Mobil effective as of January 1, 1998 covering Mobil's interest in 39,636 acres
in the Lobo Trend.  Partial consideration for the Lobo Lease is in the form of
future deliveries of 4 Bcf of gas, commencing May 1, 1998 and terminating
December 31, 1998.  On April 23, 1998, the Company entered into a contract to
secure delivery of this volume of gas for consideration of $9.98 million.  The
remainder of the net proceeds from the sale of the Old Notes will be used for
general corporate purposes, including development, drilling and exploitation
activities and property acquisitions. Although the Company is continually
evaluating and pursuing potential property acquisitions, the Company has no
material commitments, contracts, understandings or arrangements at the present
time with respect to any particular acquisition. The allocation of the Company's
net proceeds from the sale of the Old Notes, together with other available
capital, for general corporate purposes, including development, drilling and
exploitation activities and future property acquisitions, is discretionary and
will depend upon future events that cannot be predicted, including the actual
results and costs of future development and exploration drilling and other
activities, the availability and cost of oil and natural gas properties meeting
the Company's acquisition criteria and other matters beyond the control of the
Company. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources."

    Until the net proceeds from the sale of the Old Notes are utilized for
purposes described above, they will be invested in interest-bearing bank
accounts, U.S. government securities, other investment grade debt securities
and other short-term, interest-bearing investments.

             SELECTED HISTORICAL AND PRO FORMA FINANCIAL, OPERATING
                  AND OIL AND NATURAL GAS RESERVE INFORMATION

   
    The following tables set forth selected financial data (i) on an historical
basis for and as of the end of each of the years in the five-year period ended
December 31, 1997, and on a pro forma basis for the year ended December 31, 1997
and (ii) on an historical basis for the three month periods ended, and as of,
March 31, 1997 and 1998, and on a pro forma basis for the three months ended,
and as of, March 31, 1998. The historical financial data for the year ended, and
as of, December 31, 1997 have been derived from the audited Financial Statements
of the Company. The historical financial data for the three-month periods ended
March 31, 1997 and 1998 are derived from unaudited Financial Statements of the
Company but include all adjustments,consisting of normal recurring adjustments,
that the Company considers necessary for a fair presentation of its financial
position and results of operations for these periods. The results for the three
months ended March 31, 1998 are not necessarily indicative of the results for
the full year. The pro forma financial, operating and oil and natural gas
reserve data are not necessarily indicative of the operating results or
financial position that would have been achieved had the transactions to which
they give pro forma effect been effective at the date or during the period
presented or of the results that may be obtained in the future. This information
should be read in conjunction with "Management's Discussion and Analysis of
Financial Condition and Results of Operations," the Company's Financial
Statements and the Notes thereto, the Statement of Revenues and Direct Operating
Expenses and the Notes thereto for the Enron Properties, the Conoco Properties

     alternative to, or more meaningful than, net income or cash flow as
     determined in accordance with GAAP or as an indicator of a company's
     operating performance or liquidity. Certain items excluded from EBITDA are
     significant components in understanding and assessing a company's financial
     performance, such as a company's cost of capital and tax structure, as well
     as historic costs of depreciable assets, none of which are components of
     EBITDA. The Company's computation of EBITDA may not be comparable to other
     similarly titled measures of other companies. The Company believes that
     EBITDA is a widely followed measure of operating performance and may also
     be used by investors to measure the Company's ability to meet future debt
     service requirements, if any. This

GENERAL

    The Company is an independent energy company engaged in the acquisition,
exploitation and development of oil and natural gas properties, principally in
the Lobo Trend of South Texas. The Company began operations in 1983 and, since
its inception, has demonstrated growth in reserves and production as a result
of acquisitions and successful drilling and development of its oil and natural
gas properties. In August 1996, the Company acquired interests in approximately
21,000 developed and undeveloped acres in the Lobo Trend for approximately
$15.3 million. In 1997, the Company participated in the drilling of 19 natural
gas wells, completing 15 capable of commercial production (a success rate of
79%).  In March and April 1998, the Company completed the Transactions.  See
"Business and Properties--The Transactions."

    The Company will continue to utilize its technical staff and technological
advances to seek to increase its oil and natural gas reserves, production and
cash flow from operations through a development program coupled with strategic
property acquisitions. The Company has in-house exploration expertise using 3-D
seismic technology to identify new drilling opportunities as well as for the
development of acquired properties.

    Through the periods presented, the Company's results of operations reflect
two tax structures (S corporations and C corporations) which have influenced,
among other things, the historical levels of its owners' compensation.
Effective July 1, 1996, the Company changed its tax filing status from an S
corporation to a C corporation. Due to this change, the Company recognized a
one-time charge of approximately $2.0 million to reflect deferred income taxes
payable as of June 30, 1996.

    The Company utilizes the "successful efforts" method of accounting for its
oil and natural gas activities as described in Note 1 of Notes to Financial
Statements of the Company.

RESULTS OF OPERATIONS

   
    The following table summarizes production volumes, average sales prices and
operating revenues for the Company's oil and natural gas operations for the
years ended December 31, 1995, 1996 and 1997 and for the three month periods
ended March 31,1997 and 1998:

    COMPARISON OF THREE MONTH PERIODS ENDED MARCH 31, 1998 AND 1997

    Oil and natural gas revenues for the three months ended March 31, 1998
increased 76% to $3.26 million from $1.85 million for the three months ended
March 31, 1997. Production volumes for natural gas for the first quarter ended
March 31, 1998 increased 105% to 1,487 Mmcf from 725 Mmcf for the first quarter
of 1997. Average natural gas prices decreased 15% to $2.07 per Mcf for 1998
from $2.44 per Mcf for 1997. The increase in natural gas production in 1998 was
due to new wells resulting from the Company's 1997 drilling program and the 
increased production from certain existing wells due to the Company's 1997 
workover program.
    

   
    Oil and natural gas production costs for the three months ended March 31,
1998 increased 12% to $475,000 from $426,000 for the three months ended March
31, 1997, primarily due to the increase in production. However, actual
production costs per equivalent unit decreased to $.30 per Mcfe for the first
quarter ended March 31, 1998 from $.57 per Mcfe for the first quarter ended 
March 31, 1997. The decrease on an equivalent basis was due to per unit
reductions in workover costs, the increased production volumes during the first
quarter of 1998 due to placing new wells on line and the Company's 1997 
workover program.
    

   
    Depreciation, depletion and amortization ("DD&A") expense for the three
months ended March 31, 1998 increased 37% to $1.35 million from $986,000 for the
same period in 1997. The increase was due primarily to the increased production
during the first quarter of 1998, but was proportionally less than the
percentage increase in production volumes, due to the fact that a $238,000
impairment charge was taken in the first quarter of 1997, compared with no
corresponding charge in 1998.
    

   
    General and administrative expense increased 64% due to the addition of
several new employees and their related benefits, plus increases in legal and
professional fees.
    

   
    Interest expense, net of capitalized interest, for the three months ended
March 31, 1998 increased 141% to $890,000 from $370,000 for the same period in
1997. The increase was due to the higher levels of debt outstanding and higher
prevailing interest rates on the debt outstanding under the T.E.P. Financing,
during the first quarter of 1998 as compared to the first quarter of 1997. 
    

   
    Income tax expense increased to $105,000 for the first three months of 1998,
compared to an income tax benefit of ($37,000) for the first three months of
1997, resulting from the pre-tax income recognized in the first quarter of 1998
compared to the pre-tax net loss in 1997. The effective tax rate for both
periods was 35%.
    

   
    Net income for the three months ended March 31, 1998 was $196,000 compared
to a loss of $68,000 for the three months ended March 31, 1997, primarily as a
result of the factors discussed above.
    

COMPARISON OF YEARS ENDED DECEMBER 31, 1997 AND 1996

    Oil and natural gas revenues for the year ended December 31, 1997 increased
153% to $9.1 million compared to $3.6 million for 1996. Production volumes for
natural gas during the year ended December 31, 1997 increased 178% to 3,685
Mmcf from 1,324 Mmcf for 1996. Average gas prices increased 8.3% to $2.33 per
Mcf for 1997 from $2.15 per Mcf for 1996.  During April 1998, average
natural gas prices were $2.20 per Mmbtu. The increase in





                                      -30-
<PAGE>   35
natural gas production was due to the 1996 Lobo Acquisition and the Company's
workover and drilling program with respect to the properties acquired and
existing properties.

    Oil and natural gas production costs for the year ended December 31, 1997
decreased 3% to $1.87 million from $1.93 million for 1996 primarily due to the
sale of the Company's Hull Field oil properties in August 1996 that
historically had incurred much higher lease operating costs than the Company's
average Lobo Trend natural gas wells. Accordingly, production costs per
equivalent unit decreased to $0.49 per Mcfe for 1997 from $1.25 per Mcfe for
1996. The per unit cost decreased as a result of increased production of
natural gas, which has lower per unit operating costs, and the Company's
disposition in August 1996 of oil producing properties having higher operating
costs.

   
    DD&A expense for the year ended December 31, 1997 increased 225% to $3.9
million from $1.2 million for the same period in 1996. This increase was due to
the increased production during 1997.
    

    Exploration expense increased from $46,000 in 1996 to $333,000 in 1997, due
primarily to the expiration of the terms of certain leases that had not been
developed.

    General and administrative expense for the year ended December 31, 1997
increased 131% to $980,000 from $424,000 for 1996, primarily as a result of
increases in the number of employees and related benefits, plus increased legal
and professional fees.

    Interest expense, net of capitalized interest, for the year ended December
31, 1997 increased 127% to $2.1 million from $924,000 for 1996. This increase
in interest expense was due to increased debt levels in the second half of 1996
and in 1997 resulting from funds borrowed to acquire and develop the Lobo Trend
properties.

    The net loss for the year ended December 31, 1997 decreased to $7,000 from
a net loss of $2.5 million for 1996, as a result of the factors described above
and the $2.0 million income tax charge related to the Company's conversion from
an S corporation to a C corporation in 1996.

COMPARISON OF YEARS ENDED DECEMBER 31, 1996 AND 1995

    Oil and natural gas revenues for 1996 increased 72% to $3.6 million from
$2.1 million for 1995. Production volumes for natural gas for 1996 increased
208% to 1,324 Mmcf from 430 Mmcf for 1995. Average natural gas prices increased
29% to $2.15 per Mcf for 1996 from $1.67 per Mcf for 1995. The increase in oil
and natural gas production was due to the 1996 Lobo Acquisition and the
Company's subsequent workover and recompletion program with respect to the
properties acquired.

    Oil and natural gas production costs for 1996 increased 58% to $1.9 million
from $1.2 million for 1995. Oil and natural gas production costs increased due
to increased production resulting from the 1996 Lobo Acquisition and the
workover and recompletion program with respect to the properties acquired.
Production costs per equivalent unit for 1996 decreased to $1.25 per Mcfe from
$1.36 per Mcfe in 1995. The per unit cost decreased as a result of increased
production of natural gas, which has lower per unit operating costs than oil
producing properties.

    DD&A expense for 1996 decreased to $1.2 million from $1.3 million for 1995,
primarily as a result of the disposition in July 1996 of oil producing
properties having a high DD&A rate, which offset increased DD&A expense related
to the Lobo Trend properties.

    Exploration expense decreased from $850,000 in 1995 to $46,000 in 1996 due
to the Company's focus on development drilling in the Lobo Trend properties.

    General and administrative expense for 1996 decreased 44% to $424,000 from
$763,000 for 1995 due primarily to staff and salary reductions which occurred
in late 1995.

    Interest expense, net of capitalized interest, for 1996 decreased 15% to
$924,000 from $1,084,000 for 1995. This decrease was primarily due to increased
capitalized interest in 1996 related to development activity on the Lobo Trend
properties.

    The provision for income taxes in 1996 of $1.8 million was composed
primarily of the $2.0 million income tax charge related to the Company's
conversion from an S corporation to a C corporation in 1996.

<PAGE>   36
    The net loss for 1996 increased to $2.5 million from a loss of $27,000 for
1995 primarily as a result of the factors discussed above and as a result of
the decrease in the gain on sale of oil and natural gas properties from 1995 to
1996 and implementation of SFAS 109 upon the Company's conversion from an S
corporation to a C corporation in 1996.

LIQUIDITY AND CAPITAL RESOURCES

   
    First Quarter Liquidity Discussion.  Cash flows (used in) provided by
operating activities from the Company's operations were ($66,000) and $3.4
million for the three months ended March 31, 1997 and 1998, respectively. The
increase in operating cash flows for the three months ended March 31, 1998 over
the same period in 1997 was due to increased production, revenue and operating
income as a result of the Company's 1997 drilling and workover programs. Cash
flows from operating activities were negative for the first quarter of 1997
principally due to the Company's net loss for that quarter.
    

   
    Cash flows used in investing activities by the Company were $801,000 and
$2.1 million for the three months ended March 31, 1997 and 1998, respectively,
and almost exclusively applied to property additions through drilling and
development activities. The increase for the three months ended March 31, 1998
over the same period in 1997 was due to the increased number of new wells
drilled and completed. For the three months ended March 31, 1998, two new wells
were drilled and three wells were completed; only one new well was drilled and
one completed for the same period in 1997.
    

   
    Cash flows provided by (used in) financing activities were $329,000 and
($1.4 million) for the three months ended March 31, 1997 and 1998,
respectively. The increase in the amount of cash flows used in financing
activities during the first quarter of 1998 was due to higher amounts of
principal repayments of indebtedness compared to amounts of borrowings under
the T.E.P. Financing for the three months ended March 31, 1998; during the
first quarter of 1997, the amounts of borrowings exceeded the amounts of
repayments. Under the terms of the T.E.P. Credit Agreement, principal was
payable as a percentage of net revenue. Accordingly, the principal repayments
increased as a result of the increased revenues for the three months ended
March 31, 1998 compared to the same period in 1997.
    

   
    Fiscal Years Liquidity Discussion.  Cash flows (used in) provided by
operating activities from the Company's operations were ($2.3) million, $848,000
and $3.5 million for the years ended December 31, 1995, 1996 and 1997,
respectively. The increases in 1996 and 1997 were primarily attributable to
increased production resulting from the 1996 Lobo Acquisition. Cash and working
capital in 1998 are and are expected to be provided through internally generated
cash flows, bank borrowings and debt or equity financing.
    

    Cash flows provided by (used in) investing activities by the Company were
$1.3 million, $(14.8) million and ($15.0) million in 1995, 1996 and 1997,
respectively. Property additions through acquisition, exploration and
development activities were the primary reasons for the use of funds in
investing activities. Partially offsetting these uses of funds were proceeds
from sales of oil and natural gas properties and discontinued operations in
1996 and 1995. Cash flows used in investing activities by the Company for 1997
and 1996 resulted primarily from the acquisition and development of the Lobo
Trend properties.

    Cash flows provided by the Company's financing activities were $1.4
million, $14.8 million and $11.1 million in 1995, 1996 and 1997, respectively.
In 1996 and 1997, the positive cash flows from financing activities resulted
from the funding under the T.E.P. Financing.

   
    General.  The Company's primary sources of liquidity have historically been
provided from funds generated by operations and from borrowings, including under
the T.E.P. Financing.  In April 1998, the Company completed the sale of $135.0
million original principal amount of Old Notes.  Approximately $28.0 million of
the net proceeds from the sale of the Old Notes was used to repay the
indebtedness outstanding under the T.E.P. Financing. See "Use of Proceeds."
During May 1998, the Company entered into the Credit Facility, as described
below under "--Financing Arrangements."
    

   
    As of the date of this Prospectus, the Company has $135.0 million in
outstanding senior indebtedness under the Old Notes due April 1, 2005 and no
indebtedness outstanding under the Credit Facility. Under the Credit Facility,
the principal balance outstanding will be due and payable on May 28, 2002. For a
more comprehensive discussion of the Company's indebtedness, including a
description of negative and financial covenants imposed on the Company, see
"--Financing Arrangements" and "Description of the Notes--Certain Covenants." 
    

    The Company's revenues, profitability, future growth and ability to borrow
funds and obtain additional capital, and the carrying value of its properties,
are substantially dependent on prevailing prices of oil and natural gas. It is
impossible to predict future oil and natural gas price movements with
certainty. Declines in prices received for oil and natural gas would have an
adverse effect on the Company's financial condition, liquidity, ability to
finance capital expenditures and results of operations. Lower prices would also
impact the amount of reserves that can be produced economically by the Company.

   
    The Company has experienced and expects to continue to experience
substantial working capital requirements primarily due to the Company's
development program. Capital expenditures for 1998 are estimated to be
approximately $24.0 million. Substantially all of the capital expenditures will
be used to fund drilling activities, property acquisitions and 3-D seismic
surveys in the Company's project areas. The Company's plan anticipates drilling
29 gross (25 net) wells in 1998. While the Company believes that the net
proceeds from the sale of the Old Notes, cash flows from operations and
borrowings under the Credit Facility should allow the Company to implement its
present development drilling strategy, additional financing may be required in
the future to fund the Company's further growth through acquisitions of
additional properties. In the event such capital resources are not available to
the Company, its property acquisitions would be curtailed. See "Risk
Factors--Future Need for and Availability of Capital."
    

FINANCING ARRANGEMENTS

    In August 1996, the Company entered into the T.E.P. Financing, which
provided for an aggregate term loan amount of $42.2 million, of which a maximum
of $16.3 million was available for oil and natural gas property acquisitions
and $25.9 million was available for development drilling, subject in each case
to borrowing base limitations. The Company used approximately $28.0 million of
the net proceeds from the sale of the Old Notes to repay all of the outstanding
indebtedness under the T.E.P. Financing.

    Under the T.E.P. Financing, principal was due and payable based upon a
percentage of the Company's gross revenues less operating expenses and
allowable general and administrative expenses. At December 31, 1997, the
Company had borrowed and repaid approximately $2.9 million under the T.E.P.
Financing, and $28.4 million in borrowings were outstanding. Indebtedness under
the T.E.P. Financing bore interest at various rates, depending upon total
utilization of the facility and other factors. At March 27, 1998, a portion of
the outstanding indebtedness under the T.E.P. Financing bore interest at the
prime rate of Citibank, N.A. (the "Prime Rate") (which was 8.5%) plus 3%, a
portion bore interest at the Prime Rate plus 7% and a portion bore interest at
the lender's choice of the Prime Rate plus 4% or LIBOR (as defined) plus 6
1/2%. As of March 27, 1998, the weighted average stated interest rate of
outstanding indebtedness under the T.E.P. Financing was 12.8%. The Company's
obligations under the T.E.P. Financing were secured by all of the oil and
natural gas properties of the Company, as well as the stock of the





                                      -32-
<PAGE>   37
Company.  The T.E.P. Financing contained financial covenants, the most
restrictive of which pertained to the payment of dividends, distributions to
shareholders and the Company's working capital ratio. The T.E.P. Financing also
contained administrative covenants.

    In addition, in August 1996 the Company granted Cambrian Capital Partners,
L.P., an affiliate of the T.E.P.  Financing lender ("Cambrian"), a 30% Net
Profits Interest (as defined in the Net Profits Interest Conveyance dated
August 12, 1996), net to the Company's interest, in all of the Company's
properties, including those acquired in the 1996 Lobo Acquisition; however, no
net profits payments were to be made to Cambrian under the terms of the Net
Profits Interest until the earlier to occur of the payment in full of the
T.E.P. Financing or August 12, 2001. After Cambrian received cash proceeds of
$10.0 million under the Net Profits Interest Conveyance, the Net Profits
Interest was to be reduced from 30% to 15%. As part of the T.E.P. Financing,
the Company also granted to Cambrian a warrant to purchase up to 5% of the
Company's common stock until August 12, 2001. The value assigned to the Net
Profits Interest and warrant was recorded as a discount to the loan proceeds.
The Company used approximately $11.0 million of the net proceeds from the sale
of the Old Notes to acquire the Net Profits Interest. See "Use of Proceeds."

   
    In May 1998, the Company entered into the Credit Facility with Christiania
Bank og KreditKasse ("Christiania") as lender and administrative agent, pursuant
to the terms of that certain Credit Agreement between the Company and
Christiania dated effective as of May 15, 1998 (the "Credit Agreement"). The
Credit Facility provides for loans in an outstanding principal amount not to
exceed $50.0 million at any one time, subject to a borrowing base to be
determined semi-annually by the administrative agent (the initial borrowing base
is $30.0 million), and the issuance of letters of credit in an outstanding face
amount not to exceed $6.0 million at any one time with the face amount of all
outstanding letters of credit reducing, dollar-for-dollar, the availability of
loans under the Credit Facility. Under the Credit Facility, the principal
balance outstanding will be due and payable on May 28, 2002, and each letter of
credit shall be reimbursable by the Company when drawn, or if not then otherwise
reimbursed, paid pursuant to a loan under the Credit Facility. Commencing on
March 31, 1999, and continuing until its stated maturity, the maximum amount
available for borrowings and letters of credit under the Credit Facility will
not only be adjusted (increased or decreased, as applicable) by the semi-annual
borrowing base determination, but also (i) decreased by quarterly mandatory
reductions in the borrowing base (initially $2.3 million per quarter) and (ii)
adjusted for sales of collateral having an aggregate value exceeding the lesser
of $4.0 million per year or 5% of the Company's total proved reserve values.
    
        
    The interest rate for each borrowing under the Credit Facility will be
calculated at either (i) the ABR rate (as described below), or (ii) the
Eurodollar Rate (as described below) plus 1.75%, at the election of the Company.
Interest on the borrowings under the Credit Facility will be due (i) with
respect to loans bearing interest at the ABR rate, quarterly in arrears and at
maturity, and (ii) with respect to loans bearing interest at the Eurodollar
Rate, on the last day of each relevant interest period and, in the case of any
interest period longer than three months, on a quarterly basis. The Company's
obligations under the Credit Facility are secured by substantially all of the
oil and natural gas assets of the Company, including accounts receivable and
material contracts, equipment and gathering systems. The proceeds of the Credit
Facility may be used to finance working capital needs and for general corporate
purposes of the Company in the ordinary course of its business.

    Under the Credit Facility, "ABR" means the highest of (i) the interest rate
announced publicly by Christiania as its prime rate in effect in its principal
office in New York, (ii) the secondary market rate for three-month certificates
of deposit (adjusted for statutory reserve requirements) plus 1% and (iii) the
federal funds effective rate from time to time plus 0.5%. "Eurodollar Rate"
means the rate (adjusted for statutory reserve requirements of eurocurrency
liabilities) at which eurodollar deposits for one, two, three or six (or, if
available and acceptable to the Credit Facility lenders, nine or twelve) months
(as selected by the Company) are offered to Christiania in the Interbank
eurodollar market.

   
    The Credit Agreement contains certain covenants by the Company, including
(i) limitations on additional indebtedness and on guaranties by the Company
except as permitted under the Credit Agreement, (ii) limitations on additional
investments except those permitted under the Credit Agreement and (iii)
restrictions on dividends or distributions on or repurchases or redemptions of
capital stock by the Company except for those involving repurchases of MHI
capital stock which may not exceed $500,000 in any fiscal year. In addition, the
Credit Agreement requires the Company to maintain and comply with certain
financial covenants and ratios, including a minimum interest coverage ratio, a
minimum current ratio and a covenant requiring that the Company's general and
administrative expenses may not exceed 12.5% of the Company's gross revenues in
any calendar year.      
    

   
    As of May 31, 1998, the Company had no outstanding indebtedness under the
Credit Facility (including outstanding letters of credit issued for its
benefit).

</TABLE>

    The Company has budgeted capital expenditures of approximately $24.0
million for 1998. Substantially all of the capital expenditures will be used to
fund drilling activities, property acquisitions and 3-D seismic surveys in the
Company's project areas. The Company intends to drill approximately 29 gross
(25 net) wells in 1998. The actual amounts of capital expenditures and number
of wells drilled may differ significantly from such estimates. See "Business
and Properties -- The Transactions."

   
HEDGING ACTIVITIES
    

   
    In an effort to achieve more predictable cash flows and earnings and reduce
the effects of the volatility of the price of oil and natural gas on the
Company's operations, the Company has hedged in the past, and in the future
expects to hedge oil and natural gas prices through the use of swap contracts
and put options. While the use of these hedging arrangements limits the downside
risk of adverse price movements, it also limits future gains from favorable
movements. The Company accounts for these transactions as hedging activities
and, accordingly, gains and losses are included in oil and natural gas revenues
in the periods in which the related production occurs. The Company does not
engage in hedging arrangements in which the production amounts are in excess of
the Company's actual production.
    

    Although the Company's former hedging contracts in effect were terminated
at the closing of the sale of the Old Notes, the Company has entered into
additional hedging contracts. On April 7, 1998, the Company entered into a
costless collar contract with a third party which provides for a floor price of
$2.25 per Mmbtu and a ceiling price of $2.99 per Mmbtu.  The collar hedges a
monthly volume of 450,000 Mmbtu from May 1, 1998 through April 30, 1999.  Any
gas revenues over $2.99 per Mmbtu will be paid by the Company to the third
party.  Conversely, the third party agreed to pay the Company all revenues
equal to the difference between $2.25 per Mmbtu and any price below $2.25 per
Mmbtu; any gas revenues under $2.25 per Mmbtu will be paid to the Company.  In
addition, on April 7, 1998 in a separate transaction with a different third
party, the Company purchased put options with a strike price of $2.25 per Mmbtu
for approximately $230,000.  The put options hedge a volume of 150,000 Mmbtu per
month from May 1, 1998 to April 30, 1999.  All prices are relative to a Houston
Ship Channel Index.

    The annual average oil and natural gas prices received by the Company have
fluctuated significantly over the past three years. The Company's weighted
average natural gas price received per Mcf (including the effects of hedging
transactions) was $1.67, $2.15 and $2.33 during the years ended December 31,
1995, 1996 and 1997, respectively. Hedging transactions resulted in a $0.24 and
$0.32 reduction in the Company's weighted average natural gas price received
per Mcf in 1996 and 1997, respectively.

    The following table sets forth the increase (decrease) in the Company's
natural gas and oil revenues as a result of hedging transactions and the
effects of hedging transactions on price per Mcf during the periods indicated.

NATURAL GAS BALANCING

    The Company incurs certain natural gas production volume imbalances in the
ordinary course of business and utilizes the sale method to account for such
imbalances. Under this method, income is recorded based on the Company's net
revenue interest in production taken for delivery. Management does not believe
that the Company had any material imbalances as of December 31, 1996 or 1997.

EFFECTS OF INFLATION AND CHANGES IN PRICE

    The Company's results of operations and cash flows are affected by changes
in oil and natural gas prices. If the price of oil and natural gas increases
(decreases), there could be a corresponding increase (decrease) in the
operating cost that the Company is required to bear for operations, as well as
an increase (decrease) in revenues. Inflation has had only a minimal effect on
the Company.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

   
    In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, Reporting Comprehensive Income, which is effective for fiscal years
beginning after December 15, 1997. SFAS No. 130 establishes standards for
reporting and display of comprehensive income and its components (revenues,
expenses, gains and losses) in a full set of general- purpose financial
statements. It requires (a) classification of items of other comprehensive
income by their nature in a financial statement and (b) display of the
accumulated balance of other comprehensive income separate from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. The adoption of SFAS No. 130 did not have a material effect 
on the Company's financial position, results of operations or cash flows.
    

   
    In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments
of an Enterprise and Related Information, which is effective for fiscal years
beginning after December 15, 1997. SFAS No. 131 establishes standards for
reporting information about operating segments in annual financial statements
and requires selected information about operating segments in interim financial
reports issued to shareholders. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
SFAS No. 131 supersedes SFAS No. 14, Financial Reporting for Segments of a
Business Enterprise, but retains the requirement to report information
regarding major customers. The Company plans to adopt SFAS No. 131 for the year
ended December 31, 1998 and, because the Company operated in only one segment,
does not expect the adoption thereof to have a material effect on the Company's
financial statement disclosures.
    

   
    In March 1998, the FASB issued SFAS No. 132, Employers' Disclosures
about Pensions and Other Postretirement Benefits, which is effective for fiscal
years beginning after December 15, 1997.  SFAS No. 132 revises employers'
disclosures about pension and other postretirement benefit plans.  It
standardizes the disclosure requirements for pensions and other postretirement
benefits to the extent practicable, requires additional information on changes
in the benefits obligations and fair values of plan assets that will facilitate
financial analysis, and eliminates certain disclosures that are no longer as
useful as they were when SFAS No. 87, Employers' Accounting for Pensions, and
No. 88, Employers' Accounting for Settlements and Curtailments of Deferred
Benefit Pension Plans and for Termination Benefits, were issued.  Because the
Company does not currently have pension or other postretirement benefits,
management does not expect the adoption of SFAS No. 132 to have a material
affect on the Company's financial statement disclosures.
    

   
    In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which is effective for fiscal years
beginning after June 15, 1999. SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It also requires that
an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those items at fair value. If
certain conditions are met, a derivative may be specifically designated as (a) a
hedge of the exposure to changes in the fair value of a recognized asset or
liability or an unrecognized firm commitment, (b) a hedge of the exposure to
variable cash flows of a forecasted transaction, or (c) a hedge of the 
foreign currency exposure of a net investment in a foreign operation, an 
unrecognized firm commitment, an available-for-sale security, or a
foreign-currency-denominated forecasted transaction. As discussed in Note 5 to
the Financial Statements, the Company has historically hedged a portion of its
future gas production using gas swap contracts. These contracts are a hedge of
the Company's exposure to the variability of future cash flows due to potential
decreases in gas prices. For a derivative designated as hedging the exposure to
variable cash flows of a forecasted transaction (referred to as a cash flow
hedge), the effective portion of the derivative gain or loss is initially
reported as a component of other comprehensive income (outside earnings) and
subsequently reclassified into earnings when the forecasted transaction affects
earnings. The ineffective portion of the gain or loss is reported in earnings
immediately. The extent of the impact of adopting SFAS No. 133 on the Company's
financial position, results of operations, or cash flows will be a function of
the open derivative contracts at the date of adoption. If the Company had
adopted SFAS No. 133 as of March 31, 1998, the Company would have recorded an
unrealized loss of approximately $1.2 million (net of tax) as a component of
other comprehensive income.

                            BUSINESS AND PROPERTIES

OVERVIEW

    The Company is engaged in the acquisition, exploitation and development of
oil and natural gas properties, principally in the Lobo Trend. The Company has
significantly expanded its production and reserve base in recent years through
development drilling and exploitation activities and by acquiring producing and
undeveloped properties.  On March 31 and April 2, 1998, the Company closed the
Transactions, pursuant to which the Company acquired interests in 170 gross (98
net) wells covering approximately 46,900 gross acres and proved reserves of 96
Bcfe as of December 31, 1997.  On April 20, 1998, the Company entered into the
Lobo Lease, pursuant to which the Company acquired leasehold interests in
undeveloped acreage covering approximately 39,636 gross acres in the Lobo
Trend, adding 43 Bcfe of net proved undeveloped reserves as of December 31,
1997.  The interests in properties acquired included acreage that is
geographically close and geologically similar to the Company's other properties.
The Company believes that these acquired properties together with its previously
existing properties have substantial development drilling and exploitation
potential. The Company has initially identified approximately 160 drilling
locations that are expected to be drilled over the next several years. The
Company used approximately $68.3 million of the net proceeds from the sale of
the Old Notes in connection with the closing of the Transactions, including the
repayment of short-term acquisition indebtedness incurred in connection with the
closing of the Enron Acquisition. At December 31, 1997, on a pro forma basis,
the Company owned interests in 280 gross (159 net) wells, approximately 95% of
which were operated by the Company, and had proved reserves totaling 191 Bcfe,
with a PV-10 Value of $203 million.

    The Lobo Trend, which is located in Webb and Zapata counties in South
Texas, covers in excess of one million gross acres and contains multi-pay
reservoirs of oil and natural gas. Since 1991, Webb and Zapata counties
collectively have constituted one of the largest onshore natural gas producing
regions in the United States. Although over 3,500 wells have been drilled and
cumulative production from the Lobo Trend since its discovery in 1973 exceeds
6.3 trillion cubic feet of natural gas equivalents, the Lobo Trend is believed
to be only partially exploited, with existing wells producing from only
approximately 125,000 acres. The primary geologic target in the Lobo Trend is
the Lobo sand series of the lower Wilcox formation, which contains three
primary objectives. Two secondary objectives also exist, one above the three
Lobo sands and one below. The Company believes that the existence of these
multi-pay reservoirs reduces drilling risk and enhances the profitability of
invested capital.

    The Company began its operations in 1983 and focused on developing
prospects in South Texas. Since the early 1990s, the Company has become an
increasingly active participant in lower risk development drilling in the Lobo
Trend, and in 1996 the Company acquired interests in approximately 21,000
developed and undeveloped acres in the Lobo Trend. The Company uses 3-D seismic
imaging and other advanced exploration technologies in the development and
exploitation of its properties. As of December 31, 1997, on a pro forma basis,
3-D seismic data had been obtained over approximately 90% of the Company's
properties. Based upon the Company's interpretation of 3-D seismic data and
wells drilled in the area, the Company has initially identified, on a pro forma
basis, approximately 160 drilling locations on its properties, 90 of which are
in the Company's proved undeveloped reserve base. During 1998, the Company
intends to drill approximately 29 gross (25 net) wells and has allocated
approximately $23.3 million of its capital expenditure budget for this purpose.
All of the Company's drilling prospects for 1998, on a pro forma basis, were
identified through the use of 3-D seismic data.

    The principal executive offices of the Company are located at 13101
Northwest Freeway, Suite 320, Houston, Texas 77040, and its telephone number is
(713) 895-0909.

                               BUSINESS STRATEGY

    Key elements of the Company's business strategy include the following:

    CONTINUE EXPLOITATION AND DEVELOPMENT PROGRAM. The Company intends to
further develop and exploit its properties, including the interests in the
properties acquired in the Transactions and subject to the Lobo Lease, which,
in the aggregate, currently include approximately 160 identified drilling
locations. The Company's development and exploitation program is focused on
lower-risk development drilling opportunities that increase production levels
and proved reserves quantities while minimizing the level of drilling risk. The
Company's strategy in identifying prospective drilling locations is founded on
rigorous analysis of 3-D seismic data which the Company has acquired on over
90% of its acreage on a pro forma basis. All of the locations scheduled to be
drilled in 1998 were identified through the interpretation of 3-D seismic data.

    TECHNICAL EXPERTISE. Members of the senior management team have
participated in the drilling of over 600 wells in South Texas which,
collectively, have produced over one trillion cubic feet of natural gas
equivalents. Each member of senior management has over 18 years of industry
experience, and two of the three members of senior management have worked
together for over ten years. The Company believes that its drilling success is
a direct result of the technical knowledge and experience of its geoscience
staff in effective interpretation of well log data and mapping of the
subsurface geology.

    OPERATIONAL CONTROL. The Company seeks to operate the wells in which it
owns an interest whenever possible. The Company believes that control over
operations allows it to more effectively control the costs, scope and timing of
drilling and other field operations. Alternatively, when this is not possible,
the Company attempts to only own interests in wells where it has a high degree
of confidence in the operator and because of its percentage ownership can
assert substantial influence with the operator. At December 31, 1997, on a pro
forma basis, the Company owned interests in 280 gross (159 net) wells,
approximately 95% of which were operated by the Company.

    PURSUE FOCUSED PROPERTY ACQUISITION PROGRAM. The Company seeks to acquire
producing properties and undeveloped acreage where it has identified
geologically complex multi-pay subsurface environments that are well suited to
the application of 3-D seismic technology. The Company believes that its
technical expertise and historical experience with such properties allows it to
identify opportunities for lower-risk development drilling and exploitation
activities.  Given the Company's historic and current scope of operations in
South Texas and its belief that attractive acquisition opportunities will
continue to become available in this area, it will focus its acquisition
efforts primarily in the Lobo Trend and other areas in South Texas. The Company
generally approaches the owners of target properties and attempts to negotiate
terms privately, although the Company will examine and bid on properties being
offered to a broader group of buyers.

    CAPITALIZE ON LOCAL RELATIONSHIPS. The Company's 15-year presence in South
Texas has resulted in numerous favorable relationships with local landowners
and their representatives. South Texas is characterized by large blocks of
privately held land which has been controlled by a small number of families for
generations. Lease blocks generally come in packages of between 5,000 and
50,000 acres. The Company believes that its favorable relationships with these
local landowners is a key advantage in its ability to access additional
undeveloped acreage acquisition opportunities. The Company intends to sustain
and expand these relationships in the area.

HISTORY OF THE COMPANY

    The Company began operations in 1983, focused on the development of
drilling prospects in South Texas, including prospects in the Lobo Trend. The
Company typically served as operator and retained a small working interest in
its prospects financing its net drilling costs through the sale of a majority
of a prospect's working interests to an industry participant. After the
development of a property, the Company typically sold its interest and
reinvested the capital in new prospects.

    To expand its operations, the Company entered into its first credit
facility in 1991. This financing allowed the Company to make several
acquisitions in South Texas outside of the Lobo Trend. All of these acquired
properties were developed and sold within four years. From 1992 to 1996, the
Company continued to acquire and dispose of properties in the Lobo Trend and
other areas of South Texas. This credit facility was retired in 1996.

    In 1995, the Company completed the sale of its non-Lobo Trend oil and
natural gas properties. In August 1996, the Company completed the 1996 Lobo
Acquisition, expanding its scope of operations in the Lobo Trend and increasing
its proved reserve base. The 1996 Lobo Acquisition resulted in a multi-year
inventory of drilling opportunities and also provided the Company with
increased working interests in its existing properties. The Company refinanced
existing indebtedness and funded the 1996 Lobo Acquisition with the proceeds
from the T.E.P.





                                      -37-
<PAGE>   42
Financing. In March and April 1998, the Company repaid the indebtedness under
the T.E.P. Financing and completed the Transactions.

THE TRANSACTIONS

    To implement the Company's business strategy, the Company completed the
Transactions concurrently with or prior to the closing of the sale of the Old
Notes. The interests acquired in the Transactions have added properties having
approximately 108 initially identified development locations. In addition, the
Transactions are expected to add approximately 96 Bcfe of estimated net proved
reserves, as of December 31, 1997. The Company believes that it has
opportunities to improve production from these properties through additional
development, drilling, reconfiguration of operations and reduction of operating
and administrative costs.

    ENRON ACQUISITION. On February 5, 1998, the Company entered into a Purchase
and Sale Agreement with Enron.  The Enron Acquisition was consummated on March
31, 1998. Pursuant to the Purchase and Sale Agreement, Enron conveyed to the
Company (i) interests in certain oil and natural gas leases covering
approximately 7,500 gross acres in Hidalgo County and Zapata County, Texas,
(ii) certain interests in leases covering approximately 37,500 gross acres
located in Webb County, Texas (the "Ranch Lands") covering the interval from
the surface of the ground down to 100 feet below the stratigraphic equivalent
of the base of the Lobo 6 sand, (iii) all of Enron's interests in and to a
2.67% non- participating term royalty interest in and to the Ranch Lands
limited in depth to the interval covered by the lease granted on the Ranch
Lands and terminating simultaneously with that portion of the lease granted on
the Ranch Lands and (iv) all seismic data owned by Enron covering the
properties described in (i) and (ii) above.

    The purchase price set forth in the Purchase and Sale Agreement for the
Enron Acquisition was $48.5 million, subject to closing and post-closing
adjustments, and the conveyance by the Company to Enron of all of the Company's
interests in certain oil and natural gas properties in Webb County, Texas.  The
actual dollar portion of the purchase price paid at closing was $45.8 million,
reflecting closing adjustments, including net production accruing to Enron's
account since January 1, 1998; this amount is subject to further post-closing
adjustments.  The dollar portion of the purchase price was paid in the form of
a promissory note issued by the Company in the original principal amount of
$45.8 million (which amount reflected the closing adjustments) and bore
interest at the rate of 8% per annum.  This promissory note matured on April 2,
1998, the closing date of the sale of the Old Notes and the Conoco Acquisition,
and the Company used a portion of the net proceeds from the sale of the Old
Notes to repay this short-term acquisition indebtedness. See "Use of Proceeds."
In addition, the Company granted to Enron a non-exclusive license to use the
seismic data it conveyed to the Company.

    Pursuant to the Purchase and Sale Agreement, the Company acquired the
properties on an "as is" basis. The Purchase and Sale Agreement also provided
for limited environmental indemnities. In general, Enron must indemnify the
Company for environmental conditions exceeding $50,000, provided that the
Company notifies Enron of such condition within 180 days following the closing.
The Company must indemnify Enron for all other environmental liabilities
incurred by Enron, including claims arising in whole or in part from the sole
or concurrent negligence or gross negligence of Enron.

    CONOCO ACQUISITION. On February 20, 1998, the Company entered into a
Purchase and Sale Agreement with Conoco.  The Conoco Acquisition was
consummated on April 2, 1998.  Pursuant to the Purchase and Sale Agreement,
Conoco conveyed to the Company a leasehold interest in all of Conoco's
interests in approximately 39,000 gross acres located in Webb County, Texas
covering the interval from the surface of the ground down to 100 feet below the
stratigraphic equivalent of the base of the Lobo 6 sand. As consideration for
the rights and property conveyed by Conoco as described above, the Company paid
at closing $22.5 million, which reflected certain closing adjustment provisions
similar to those provided for in the Enron Acquisition Purchase and Sale
Agreement. The Company used a portion of the net proceeds from the sale of the
Old Notes to pay the purchase price of the Conoco Acquisition.  See "Use of
Proceeds."

    Pursuant to the Purchase and Sale Agreement, the Company acquired the
properties on an "as is" basis. The Purchase and Sale Agreement also provided
for limited environmental indemnities.  In general, Conoco must indemnify the
Company for any environmental condition exceeding $50,000 of which the Company
became aware after the closing, provided that the Company notifies Conoco of
such condition within 180 days following the closing. The Company must
indemnify Conoco for all other environmental liabilities incurred by Conoco,
including claims arising in whole or in part from the sole or concurrent
negligence, gross negligence or strict liability of Conoco.

LOBO LEASE TRANSACTION

    By agreement dated April 20, 1998, the Company acquired from Mobil certain
leasehold interests in undeveloped acreage in the Lobo Trend in Webb County,
Texas (the "Lobo Lease").  Under this agreement, Mobil assigned to the Company
its interests in two existing leases and granted by lease interests in
additional undeveloped acreage pursuant to an oil and gas lease having a
primary term of seven years.  The lease, which has an effective date of January
1, 1998, covers 39,636 gross acres and covers the interval from the surface of
the ground down to 100 feet below the stratigraphic equivalent of the base of
the Lobo 6 Sand.  Excluded from the lease grant are existing productive wells
and certain drilling units on the subject properties.  The lease contains
provisions obligating the Company to indemnify Mobil for certain liabilities
incurred by Mobil as a result of the Company's operations on the Lobo Lease
properties, including liabilities for violations of environmental laws.

    The Company and Mobil also agreed that effective May 1, 1998, Michael would
be appointed operator with respect to the properties covered by the Lobo Lease
pursuant to a joint operating agreement between them.  In order to ensure an
orderly transition of the operator's duties, the Company and Mobil entered into
a transition services agreement, whereby Mobil would continue certain
accounting, administrative and regulatory operations with respect to Lobo Lease
production and operations through August 31, 1998; for these services, the
Company agreed to pay Mobil $25,000.

    As part of the consideration for the Lobo Lease and related matters, the
Company agreed to make future deliveries to Mobil of 4.0 Bcf of natural gas.  On
April 23, 1998, the Company entered into a contract to secure delivery of this
volume of natural gas from a third party for consideration of $9.98 million.

    The interests acquired under the Lobo Lease are estimated to contain net
proved undeveloped reserves of 43 Bcfe of natural gas as of December 31, 1997.
The Lobo Lease transaction increases to 100% the Company's working interest in
an estimated 93 development locations that have been identified to date.  The
Company believes that it has opportunities to improve production and cash flows
from the properties subject to the Lobo lease through additional drilling.

PRINCIPAL OIL AND NATURAL GAS PROPERTIES

    The Company owns interests in developed and undeveloped properties in South
Texas, primarily in the Lobo Trend and undeveloped acreage in South Texas. At
December 31, 1997, on a pro forma basis, the Company held 78,361 gross (66,093
net) acres in the Lobo Trend area. On a pro forma basis, the Company had drilled
wells on approximately 26% of its total net acreage, as of December 31, 1997.
The Company's Lobo Trend properties represented substantially all of its
reserves and PV-10 Value, as of December 31, 1997, on a pro forma basis. The
Company owns working interests ranging from 10% to 100% in its Lobo Trend
properties and is the operator of over 95% of the wells in which it has an
interest.

    The Lobo Trend in Webb and Zapata Counties in South Texas is one of the
largest natural gas producing regions in the United States and, at December 31,
1997, approximately 22 drilling rigs were active in the Lobo Trend for over
nine oil and natural gas companies. The primary geologic target in the Lobo
Trend is the Lobo sand series of the Lower Wilcox formation, which contains
multiple pay sands over an extensive interval that can be as large as 800 feet
in some areas of the Lobo Trend. The primary objectives in the Lobo Trend are
the Lobo 1 and Lobo 6 sands. Other pay sands exist at shallower and deeper
horizons in certain areas of the trend. Extensive faulting has trapped
hydrocarbons in the Lobo Trend producing horizons and has created a complex
geological environment. Until recently, 2-D seismic and subsurface well control
were the primary means for developing the field. The introduction of 3-D
seismic to the area in the early 1990s has improved drilling success rates, and
the Company has similarly experienced an overall increase in its drilling
success rates in the Lobo Trend as technology has evolved.

   
    

    The Company's Lobo Trend production is from reservoirs at depths between
6,000 to 14,000 feet. Most of the production horizons are of low permeability
and must be fracture stimulated to improve rates of production. As a result, a
typical well has a high initial production rate which declines rapidly and is
followed by a long period of production at a lower rate with a gradual decline.

(1) PV-10 Value represents the present value of estimated future net revenues
    before income tax discounted at 10% using prices in effect at the end of the
    respective periods presented and including the effects of hedging
    activities. In accordance with applicable requirements of the SEC, estimates
    of the Company's proved reserves and future net revenues are made using oil
    and natural gas sales prices estimated to be in effect as of the date of
    such reserve estimates and are held constant throughout the life of the
    properties (except to the extent a contract specifically provides for
    escalation). The average prices used in calculating historical PV-10 Value
    as of December 31, 1997 were $15.91 per Bbl of oil and $2.42 per Mcf of
    natural gas, compared to average prices used as of December 31, 1996 of
    $23.86 per Bbl of oil and $2.76 per Mcf of natural gas. The average prices
    used in calculating the pro forma PV-10 Value as of December 31, 1997 were
    $13.71 per Bbl of oil and $2.46 per Mcf of natural gas. Average prices at
    April 30, 1998 were $12.34 per Bbl of oil and $2.38 per Mcf of natural gas.

    There are numerous uncertainties inherent in estimating quantities of
proved oil and natural gas reserves and in projecting future rates of
production and timing of development expenditures, including many factors
beyond the control of the producer. The reserve data set forth herein
represents estimates only. Reserve engineering is a subjective process of
estimating underground accumulations of oil and natural gas that cannot be
measured in an exact manner, and the accuracy of any reserve estimate is a
function of the quality of available data and of engineering and geological
interpretation and judgment. As a result, estimates made by different engineers
often vary. In addition, results of drilling, testing and production subsequent
to the date of an estimate may justify revision of such estimates, and such
revisions may be material. Accordingly, reserve estimates are generally
different from the quantities of oil and natural gas that are ultimately
recovered. Furthermore, the estimated future net revenues from proved reserves
and the present value thereof are based upon certain assumptions, including
future prices, production levels and costs, that may not prove correct. See
"Risk Factors--Uncertainties of Estimates of Reserves and Future Net Revenues."

    No estimates of proved reserves comparable to those included herein have
been included in reports to any federal agency.

    Undeveloped acreage includes leased acres on which wells have not been
drilled or completed to a point that would permit the production of commercial
quantities of oil and natural gas, regardless of whether or not such acreage
contains proved reserves. A gross acre is an acre in which an interest is
owned. A net acre is deemed to exist when the sum of fractional ownership
interests in gross acres equals one. The number of net acres is the sum of the
fractional interests owned in gross acres expressed as whole numbers and
fractions thereof.

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

   
     From April 1, 1998 through June 26, 1998, the Company participated in
drilling activities on a total of 8 gross (5.34 net) wells, four of which have
been completed as commercial producers, three of which are currently being
drilled and one of which was a dry hole.
    

Oil and Natural Gas Marketing and Transportation

    The revenues generated by the Company's operations are highly dependent
upon the prices of and demand for oil and natural gas. The price received by
the Company for its oil and natural gas production depends on numerous factors
beyond the Company's control. Historically, the markets for oil and natural gas
have been volatile and are likely to continue to be volatile in the future.
Prices for oil and natural gas are subject to wide fluctuation in response to
relatively minor changes in the supply and demand for oil and natural gas,
market uncertainty and a variety of additional factors.  These factors include
the level of consumer product demand, weather conditions, domestic and foreign
governmental regulations, the price and availability of alternative fuels,
political conditions in the Middle East, the actions of the Organization of
Petroleum Exporting Countries, the foreign supply of oil and natural gas and
overall economic conditions. It is impossible to predict future oil and natural
gas price movements with any certainty. Declines in oil and natural gas prices
may adversely affect the Company's financial condition, liquidity and results
of operations. See "Risk Factors--Volatility of Natural Gas and Oil Prices" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

   
     The Company currently markets all of its natural gas through Upstream
Energy Services, L.L.C. ("Upstream") pursuant to the general terms and agreement
effective as of April 1, 1996 (the "Sales Agreement"). The Company and the 
predecessor to Upstream had similar marketing arrangements from 1991 to April
1996. Under the Sales Agreement, the Company has agreed to sell, and Upstream
has agreed to market all of the natural gas produced from properties owned or
operated by the Company at the price realized by Upstream from the sale of such
natural gas production less (i) the costs incurred by Upstream in the
transportation, treating and handling of the gas prior to resale and (ii) $0.03
per Mmbtu sold, as measured at the point of delivery. The Sales Agreement is
effective for a two-year period and is renewable quarterly thereafter, subject
to either party giving 60 days written notice of termination. The Company and
Upstream are currently renegotiating the terms of the Sales Agreement and expect
to renew it on terms more favorable to the Company.  Until August 1997, the
Company's Chief Executive Officer owned an aggregate of approximately 20% of the
capital stock of Upstream. See "Certain Transactions."
    


    In conjunction with the 1996 Lobo Acquisition, Conoco (as the successor in
interest to the seller) and the Company entered into a Gas Exchange Agreement
whereby such parties agreed that the Company would deliver to Conoco all of the
natural gas produced from the leases acquired in the 1996 Lobo Acquisition at
the point(s) at which such gas enters the transmission pipelines owned by Lobo
Pipeline Company ("Lobo Pipeline") (the "delivery point") in exchange for
natural gas in the same quantity and quality delivered by Conoco at the Agua
Dulce hub near Corpus Christi, Texas. The parties' obligations under the Gas
Exchange Agreement are subject to the natural gas delivered and the pipeline
meeting certain specifications. The title to the Company gas vests in Conoco at
the delivery point, except to the extent such amount exceeds the amount of
redelivered gas at the redelivery point, in which case the Company retains
title and ownership of such excess, which is then transported by Lobo Pipeline
pursuant to an Interruptible Gas Transportation Agreement. The consideration
received by Lobo Pipeline is $0.17 per Mcf for compression, transportation and
dehydration.

    The oil and natural gas industry is highly competitive, and the Company
encounters competition from other oil and natural gas companies in all areas of
its operations, including the acquisition of seismic, lease options,
exploratory prospects and proven properties. The Company's competitors in the
Lobo Trend area include major integrated oil and natural gas companies,
including Chevron Corporation, Conoco, Mobil Corporation, Enron Corp. and Sonat
Exploration Company, and numerous independent oil and natural gas companies,
individuals and drilling and income programs. Many of the Company's
competitors, including those with whom it competes in the Lobo Trend, are
large, well-established companies with substantially larger operating staffs
and significantly greater capital resources than those of the Company and
which, in many instances, have been engaged in the oil and natural gas business
for a much longer time than the Company. Such companies may be able to pay more
for exploratory prospects and productive oil and natural gas properties and may
be able to define, evaluate, bid for and purchase a greater number of
properties and prospects than could the Company, given its limited financial
and human resources. In addition, such companies may be able to expend greater
resources on the existing and changing technologies that the Company believes
are and will be increasingly important to the current and future success of oil
and natural gas companies.

    The Company's ability to acquire additional properties in the future will
be dependent upon its ability to evaluate and select suitable properties and to
consummate transactions in this highly competitive market. The Company believes
that the technological expertise and experience of its management in exploiting
the Lobo Trend, as well as the Company's relationships with landowners in the
area, generally enable it to compete effectively in the Lobo Trend. However,
the business of developing or acquiring reserves is capital intensive,
especially in the Lobo Trend area where the land blocks typically range between
5,000 and 50,000 acres. The Company will require additional financing or
participation of industry partners to effect future acquisitions in this area.
Such additional financing may take the form of equity securities, debt
securities or some combination thereof, and there can be no assurance that such
financing will be available on terms that are acceptable to the Company.
Failure to secure such financing or to locate industry partners would adversely
affect the Company's ability to compete with these other companies for lease
acreage as it may become available. In addition, to the extent that the Company
engages in oil and natural gas exploration and production activities on
properties in geographic areas other than the Lobo Trend area, the Company may
be subject to additional competitive disadvantages due to its lack of
experience in and familiarity with prospect characteristics of those areas.

GOVERNMENTAL REGULATION

    General. Various aspects of the Company's oil and natural gas operations
are subject to extensive and continually changing regulation, as legislation
affecting the oil and natural gas industry is under constant review for
amendment or expansion. Numerous departments and agencies, both federal and
state, are authorized by statute to issue, and have issued, rules and
regulations binding upon the oil and natural gas industry and its individual
members. The Federal Energy Regulatory Commission (the "FERC") regulates the
transportation and sale for resale of natural gas in interstate commerce
pursuant to the Natural Gas Act of 1938 (the "NGA") and the Natural Gas Policy
Act of 1978 (the "NGPA"). In the past, the federal government has regulated the
prices at which oil and natural gas could be sold. While sales by producers of
natural gas and all sales of crude oil, condensate and natural gas liquids can
currently be made at uncontrolled market prices, Congress could reenact price
controls in the future. Deregulation of wellhead sales in the natural gas
industry began with the enactment of the NGPA in 1978. In 1989, Congress
enacted the Natural Gas Wellhead Decontrol Act (the "Decontrol Act"). The
Decontrol Act removed all remaining NGA and NGPA price and nonprice controls
affecting wellhead sales of natural gas effective January 1, 1993.

   
    The Company's operations currently are located primarily in Texas. Thus, the
Company's business is subject to environmental regulation on the state level
primarily by the Railroad Commission of Texas and the Texas Natural Resource
Conservation Commission. The Railroad Commission of Texas regulations may
require the Company to obtain permits and drilling bonds for the drilling of
wells. Additionally, the Railroad Commission of Texas regulates the spacing of
wells, plugging and abandonment of such wells and the remediation of
contamination caused by most types of exploration and production wastes. The
Railroad Commission requirements for remediation of contamination are, for the
most part, administered on a case-by-case basis. The Company expects that such
regulations will be formalized in the future and will in all likelihood become
more stringent.
    

    Regulation of Sales and Transportation of Natural Gas. The Company's sales
of natural gas are affected by the availability, terms and cost of
transportation. The price and terms for access to pipeline transportation are
subject to extensive regulation. In recent years, the FERC has undertaken
various initiatives to increase competition within the natural gas industry. As
a result of initiatives like FERC Order No. 636, issued in April 1992, the
interstate natural gas transportation and marketing system has been
substantially restructured to remove various barriers and practices that
historically limited nonpipeline natural gas sellers, including producers, from
effectively competing with interstate pipelines for sales to local distribution
companies and large industrial and commercial customers. The most significant
provisions of Order No. 636 require that interstate pipelines provide firm and
interruptible transportation service on an open access basis that is equal for
all natural gas suppliers. In many instances, the results of Order No.  636 and
related initiatives have been to substantially reduce or eliminate the
interstate pipelines' traditional role as wholesalers of natural gas in favor
of providing only storage and transportation services. While the United States
Court of Appeals upheld most of Order No. 636 last year, certain related FERC
orders, including the individual pipeline restructuring proceedings, are still
subject to judicial review and may be reversed or remanded in whole or in part.
While the outcome of these proceedings cannot be predicted with certainty, the
Company does not believe





                                      -43-
<PAGE>   48
that it will be affected materially differently than its competitors.

    The FERC has also announced several important transportation-related policy
statements and proposed rule changes, including a statement of policy and a
request for comments concerning alternatives to its traditional cost-of-service
ratemaking methodology to establish the rates interstate pipelines may charge
for their services. A number of pipelines have obtained FERC authorization to
charge negotiated rates as one such alternative. Both the policy statement and
individual pipeline negotiated rate authorizations are currently subject to
appeal before the U.S. Court of Appeals for the D.C. Circuit. In February 1997,
the FERC announced a broad inquiry into issues facing the natural gas industry
to assist the FERC in establishing regulatory goals and priorities in the
post-Order No. 636 environment. In October 1997, the United States Court of
Appeals for the Fifth Circuit vacated a FERC decision and remanded it to the
agency with directions to reconsider the criteria FERC used to distinguish
nonjurisdictional gathering from jurisdictional transportation on offshore
pipeline systems.

    Additional proposals and proceedings that might affect the natural gas
industry are pending before Congress, the FERC, state commissions and the
courts. The natural gas industry historically has been very heavily regulated;
therefore, there is no assurance that the less stringent regulatory approach
recently pursued by the FERC and Congress will continue.

    Oil Price Controls and Transportation Rates. Sales of crude oil, condensate
and natural gas liquids by the Company are not currently regulated and are made
at market prices. The price the Company receives from the sale of these
products may be affected by the cost of transporting the products to market.

    Environmental. Extensive federal, state and local laws regulating the
discharge of materials into the environment or otherwise relating to the
protection of the environment affect the Company's oil and natural gas
operations. Numerous governmental departments issue rules and regulations to
implement and enforce such laws, which are often difficult and costly to comply
with and which carry substantial civil and even criminal penalties for failure
to comply. Some laws, rules and regulations relating to protection of the
environment may, in certain circumstances, impose strict liability for
environmental contamination, rendering a person or entity liable for
environmental damages and cleanup costs without regard to negligence or fault
on the part of such person or entity. Other laws, rules and regulations may
restrict the rate of oil and natural gas production below the rate that would
otherwise exist or even prohibit exploration and production activities in
sensitive areas. In addition, state laws often require various forms of
remedial action to prevent pollution, such as closure of inactive pits and
plugging of abandoned wells. The regulatory burden on the oil and gas industry
increases the Company's cost of doing business and consequently affects the
Company's profitability.  The Company believes that it is in substantial
compliance with current applicable environmental laws and regulations and that
continued compliance with existing requirements will not have a material
adverse impact on the Company's operations. However, environmental laws and
regulations have been subject to frequent changes over the years, and the
imposition of more stringent requirements could have a material adverse effect
upon the capital expenditures or competitive position of the Company.

    The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") imposes liability, without regard to fault or the legality of the
original act, on certain classes of persons that are considered to be
responsible for the release of a "hazardous substance" into the environment.
These persons include the current or former owner or operator of the disposal
site or sites where the release occurred and companies that disposed or
arranged for the disposal of hazardous substances at the disposal site. Under
CERCLA such persons may be subject to joint and several liability for the costs
of investigating and cleaning up hazardous substances that have been released
into the environment, for damages to natural resources and for the costs of
certain health studies. Comparable state statutes also impose liability on the
owner or operator of a property for remediation of environmental contamination
existing on such property. In addition, companies that incur liability
frequently confront third party claims because it is not uncommon for
neighboring landowners and other third parties to file claims for personal
injury and property damage allegedly caused by hazardous substances or other
pollutants released into the environment from a polluted site.

    The Company currently owns or leases, and has in the past owned or leased,
numerous properties that have been used for the exploration and production of
oil and natural gas and for other uses associated with the oil and gas
industry.  Although the Company has followed operating and disposal practices
that it considered appropriate under applicable laws and regulations,
hydrocarbons or other wastes may have been disposed of or released on or under
the properties owned or leased by the Company or on or under other locations
where such wastes were taken for disposal. In addition, the Company owns or
leases properties that have been operated by third parties in the past. The
Company could incur liability under CERCLA or comparable state statutes for
contamination caused by wastes it generated or for contamination existing on
properties it owns or leases, even if the contamination was caused by the waste
disposal practices of the prior owners or operators of the properties.





                                      -44-
<PAGE>   49
    The Federal Solid Waste Disposal Act, as amended by the Resource
Conservation and Recovery Act of 1976 ("RCRA"), regulates the generation,
transportation, storage, treatment and disposal of hazardous wastes and can
require cleanup of hazardous waste disposal sites. RCRA currently excludes
drilling fluids, produced waters and other wastes associated with the
exploration, development or production of oil and natural gas from regulation
as "hazardous waste." A similar exemption is contained in many of the state
counterparts to RCRA. Disposal of such nonhazardous oil and natural gas
exploration, development and production wastes usually is regulated by state
law. Other wastes handled at exploration and production sites or used in the
course of providing well services may not fall within this exclusion. Moreover,
stricter standards for waste handling and disposal may be imposed on the oil
and gas industry in the future. From time to time legislation has been proposed
in Congress that would revoke or alter the current exclusion of exploration,
development and production wastes from the RCRA definition of "hazardous
wastes" thereby potentially subjecting such wastes to more stringent handling
and disposal requirements. If such legislation were enacted, or if changes to
applicable state regulations required the wastes to be managed as hazardous
wastes, it could have a significant impact on the operating costs of the
Company, as well as the oil and gas industry in general.

    The Company's operations are also subject to the Clean Air Act (the "CAA")
and comparable state and local requirements. Amendments to the CAA were adopted
in 1990 and contain provisions that may result in the gradual imposition of
certain pollution control requirements with respect to air emissions from
operations of the Company. The Company may be required to incur certain capital
expenditures in the next several years for air pollution control equipment in
connection with obtaining and maintaining operating permits and approvals for
air emissions. However, the Company believes its operations will not be
materially adversely affected by any such requirements, and the requirements
are not expected to be any more burdensome to the Company than to other
similarly situated companies involved in oil and natural gas exploration and
production activities or well servicing activities.

    The Federal Water Pollution Control Act of 1972 (the "FWPCA") imposes
restrictions and strict controls regarding the discharge of wastes, including
produced waters and other oil and natural gas wastes, into navigable waters.
These controls have become more stringent over the years, and it is probable
that additional restrictions will be imposed in the future. Permits must be
obtained to discharge pollutants into state and federal waters. The FWPCA
provides for civil, criminal and administrative penalties for unauthorized
discharges of oil and other hazardous substances and imposes substantial
potential liability for the costs of removal or remediation. State laws
governing discharges to water also provide varying civil, criminal and
administrative penalties and impose liabilities in the case of a discharge of
petroleum or its derivatives, or other hazardous substances, into state waters.
In addition, the Environmental Protection Agency has promulgated regulations
that require many oil and natural gas production sites, as well as other
facilities, to obtain permits to discharge storm water runoff. The Company
believes that compliance with existing requirements under the FWPCA and
comparable state statutes will not have a material adverse effect on the
Company's financial condition or results of operations.

    The Company maintains insurance against "sudden and accidental" occurrences
which may cover some, but not all, of the environmental risks described above.
Most significantly, the insurance maintained by the Company may not cover the
risks described above that are not attributable to a single, abrupt event.
Further, there can be no assurance that such insurance will continue to be
available to cover all such costs or that such insurance will be available at
premium levels that justify its purchase. The occurrence of a significant event
not fully insured or indemnified against could have a material adverse effect
on the Company's financial condition and results of operations.

    Regulation of Oil and Natural Gas Exploration and Production. Exploration
and production operations of the Company are subject to various types of
regulation at the federal, state and local levels. Such regulations include
requiring permits and drilling bonds for the drilling of wells, regulating the
location of wells, the method of drilling and casing wells, and the surface use
and restoration of properties upon which wells are drilled. Many states also
have statutes or regulations addressing conservation matters, including
provisions for the unitization or pooling of oil and gas properties, the
establishment of maximum rates of production from oil and gas wells and the
regulation of spacing, plugging and abandonment of such wells. Some state
statutes limit the rate at which oil and gas can be produced from the Company's
properties. See "Risk Factors--Regulatory and Environmental Risks" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Hedging Activities."

ABANDONMENT COSTS

    The Company is responsible for payment of plugging and abandonment costs on
oil and natural gas properties pro rata to its working interest. Historically,
the ultimate aggregate salvage value of lease and well equipment located on the
Company's properties has exceeded the costs of abandoning such properties.
There can be no assurance, however, that such historical trend will continue or
that the Company will be successful in avoiding additional expenses in
connection with the abandonment of any of its properties. In addition,
abandonment costs and their





                                      -45-
<PAGE>   50
timing may vary due to many factors including actual production results,
inflation rates and changes in environmental laws and regulations.

OPERATING HAZARDS AND INSURANCE

    The oil and natural gas business involves a variety of operating risks,
including the risk of fire, explosion, blowout, pipe failure, casing collapse,
unusual or unexpected formation pressures and environmental hazards such as oil
spills, gas leaks, ruptures and discharges of toxic gases, the occurrence of
any of which could result in substantial losses to the Company due to injury or
loss of life, severe damage to or destruction of property, natural resources
and equipment, pollution or other environmental damage, cleanup
responsibilities, regulatory investigation and penalties and suspension of
operations.

    In accordance with customary industry practice, the Company maintains
insurance against some, but not all, of the operating risks described above.
The Company's insurance does not cover business interruption or protect against
loss of revenues. There can be no assurance that any insurance obtained by the
Company will be adequate to cover any losses or liabilities. The Company cannot
predict the continued availability of insurance or the availability of
insurance at economic rates. The occurrence of a significant event against
which it is not fully insured or indemnified could have a material adverse
effect on the Company's financial condition or results of operations.

TITLE TO PROPERTIES

    The Company believes it has satisfactory title to all of its producing
properties in accordance with standards generally accepted in the oil and
natural gas industry. The Company's properties are subject to customary royalty
interests, liens incident to operating agreements, liens for current taxes and
other burdens that the Company believes do not materially interfere with the
use of or affect the value of such properties. Many of the Company's oil and
natural gas properties are held in the form of mineral leases. The Company's
indebtedness under the T.E.P. Financing was, and indebtedness to be incurred
under the Credit Facility is expected to be, secured by substantially all of
the Company's oil and natural gas properties.

    As is customary in the oil and natural gas industry, a preliminary
investigation of title is made at the time of acquisition of undeveloped
properties. Title investigations, including a title opinion of local counsel,
are generally completed, however, before commencement of drilling operations or
the acquisition of producing properties. The Company believes that its methods
of investigating title to, and acquiring, its oil and natural gas properties
are consistent with practices customary in the industry and that it has
generally satisfactory title to the leases covering its proved reserves.

EMPLOYEES

    At March 31, 1998, the Company employed 15 full-time employees (of which
three were engineers) and four independent contractors, including one geologist
and three gaugers. The Company believes that its relationships with its
employees are satisfactory. None of the Company's employees are covered by a
collective bargaining agreement. From time to time, the Company utilizes 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.

LEGAL PROCEEDINGS

    From time to time the Company is a party to various legal proceedings
arising in the ordinary course of business, but is not currently a party to
litigation that it believes would have a material adverse effect on the
financial condition or results of operations of the Company.

STOCK OPTION AND OTHER EMPLOYEE COMPENSATION PLANS

    During 1996, contractual stock options were granted by MHI to certain
officers and directors of the Company to purchase up to 238,750 shares of
Common Stock, each at an exercise price of $0.10 per share. These stock options
were terminated in August 1997.

    MHI has adopted the Michael Holdings, Inc. 1998 Stock Option Plan (the
"Option Plan") pursuant to which incentive stock options as defined in the
Internal Revenue Code of 1986, as amended ("ISOs"), and non-qualified





                                      -48-
<PAGE>   53
   
stock options ("NQOs") will be available for grant to key employees, consultants
and directors of MHI and the Company. The Option Plan is administered by the
Compensation Committee of the Board of Directors of MHI. A maximum of 194,000
shares, subject to adjustment for certain events of dilution, is available for
grant under the Option Plan. The Option Plan provides that the Option Agreement
applicable to the grant of options may provide that unmatured installments of
outstanding options will accelerate and become fully vested upon a "change of
control" of MHI (as defined in the Option Plan).
    

    No options have yet been granted under the Option Plan. Grants to employees
and directors will be granted under the Option Plan at an exercise price equal
to not less than the fair market value per share on the date of grant. All such
options will have terms of not more than ten years and be exercisable in
cumulative annual installments of 33.33% of the total number of shares subject
to the option grants, beginning on the first anniversary of the date of grant.

    The Option Plan provides that the plan may be amended or modified by the
Board of Directors of MHI without the approval of the shareholders of MHI,
except for any amendment which would increase the total number of shares
reserved for issuance under the Option Plan or amendments which require
shareholder approval pursuant to applicable legal requirements or securities
exchange rules.

OVERRIDING ROYALTY INTERESTS

    The Company has had in place for a number of years an arrangement, and by
written agreement dated July 24, 1997 the Company formalized such arrangement,
pursuant to which it has granted to Jerry Holditch, Vice President--Exploration
and a director of the Company, a 1.5% of 8/8ths overriding royalty interest in
all leases acquired either directly or indirectly by the Company or its
affiliates in Webb County or Zapata County, Texas. For 1995, 1996 and 1997, Mr.
Holditch received from the Company $24,187, $32,638 and $104,946, respectively,
under the overriding royalty interests. The overriding royalty interests will
not apply to any producing properties acquired by the Company except for
deepenings or sidetracks of existing wells and all new wells drilled on
acquired producing properties. According to the terms of the agreement
establishing the overriding royalty interests, the Company's obligation to
assign overriding royalty interests to Mr. Holditch expires upon the death of
Mr. Holditch or upon his termination, resignation or retirement from the
Company; however, any overriding royalty interests assigned prior to such an
event shall be unaffected by the occurrence of that event. The agreement also
restricts Mr. Holditch's ability to compete with the Company in the Lobo Trend
for a period of three years following any resignation or retirement of Mr.
Holditch from the Company. If, following Mr. Holditch's retirement or
resignation, the Company becomes financially incapable of drilling or
completing wells on locations previously identified or selected by Mr.
Holditch, the Company shall provide written authorization to Mr. Holditch to
waive the three-year non-competition provision so that Mr.  Holditch may pursue
the development of such location prospects. The Company does not anticipate
entering into any similar arrangements with any of its officers or directors in
the foreseeable future.

EMPLOYMENT AGREEMENTS

    The Company has entered into employment agreements, effective April 1,
1998, with Glenn D. Hart, Michael G. Farmar and Jerry F. Holditch, pursuant to
which Mr. Hart will serve as Chief Executive Officer of the Company, Mr. Farmar
will serve as President of the Company and Mr. Holditch will serve as Vice
President-Exploration. Each employment agreement is for a term of two years and
is automatically renewed for a period of two years from and after the first day
of each calendar quarter, commencing July 1, 1998, unless either party gives
written notice at least 30 days prior to the end of the applicable period. The
employment agreements provide for an annual base salary ($270,000 for Mr. Hart,
$180,000 for Mr. Farmar and $100,000 for Mr. Holditch), which amount may be
increased subject to periodic reviews. In addition, Messrs. Hart, Farmar and
Holditch are eligible to receive an annual incentive bonus in an amount to be
determined by the Board of Directors, but in no event will such bonus amount be
less than 50% nor more than 100% of the employee's annual base salary. The
employment agreements of Messrs. Hart and Farmar further provide that the
employee shall be granted options under the Option Plan upon terms and
conditions and in an amount to be determined by the Compensation Committee.  If
during the term of the agreement the employee's employment with the Company is
terminated without "cause" (as defined therein) or due to his resignation for
"good reason" (as defined therein), the Company will be obligated to pay the
employee payments in an amount equal to his base salary for the remaining term
of the agreement plus his accrued but unpaid bonus as of the date of
termination. The obligations of the Company under the employment agreements are
guaranteed by MHI.

    Robert L. Swanson's employment arrangements with the Company provide that
he is entitled to an annual base salary plus any year-end bonus provided to the
Company staff. The Company increased his base salary from $62,000 to $80,000
per year effective April 1, 1998. In addition, Mr. Swanson is to be provided
stock options under the Option Plan upon terms and conditions and in an amount
to be determined by the Compensation Committee.

COMPENSATION OF DIRECTORS

    Non-employee directors of the Company are eligible to receive grants of
nonqualified stock options to purchase shares of Common Stock pursuant to the
Option Plan.  Based on their relative length of service as directors, Messrs.
Tompkins and Patton are expected to receive options to purchase 7,750 shares of
Common Stock, and Mr. Smith is expected to receive an option to purchase 15,500
shares of Common Stock, at exercise prices equal to the fair market value of
the Common Stock on the date of grant.

    In addition, the Company's non-employee directors receive $2,000 plus
out-of-pocket expenses for each meeting of the Board of Directors that they
attend.

BOARD COMMITTEES

    Pursuant to the Company's Bylaws, the Board of Directors has established
standing Audit and Compensation Committees.  The Audit Committee recommends to
the Board the selection and discharge of the Company's independent auditors,
reviews the professional services performed by the auditors, the plan and
results of the auditing engagement and the amount of fees charged for audit
services performed by the auditors and evaluates the Company's system of
internal accounting controls. The Compensation Committee recommends to the
Board the compensation to be paid to the Company's directors, executive
officers and key employees and administers the compensation plans for the
Company's executive officers and directors. The members of the Audit Committee
are Messrs. Farmar, Smith and Tompkins. The members of the Compensation
Committee are Messrs. Smith, Tompkins and Patton.

                              CERTAIN TRANSACTIONS

    The Company currently markets all of its natural gas through Upstream
Energy Services, L.L.C. ("Upstream") pursuant to a Natural Gas Sales Agreement
dated as of April 1, 1996. The Company and the predecessor to Upstream had
similar marketing arrangements prior to April 1996. During 1995, 1996 and 1997,
the Company paid Upstream or its predecessor marketing fees of $57,137,
$105,726 and $219,529, respectively, under these arrangements. Until August
1997, Glenn D.  Hart, the Company's Chairman and Chief Executive Officer, owned
20% of the equity securities of Upstream and its predecessor. In such capacity,
Mr. Hart received dividends of $150,716, $26,875 and $6,000 in 1995, 1996 and
1997, respectively. Additionally, Upstream executed a promissory note in an
aggregate principal amount of $20,000 payable to Mr. Hart in connection with
the purchase by Upstream of Mr. Hart's interest. Interest on the indebtedness
accrues at a rate of 8.25% per annum. Neither Mr. Hart nor the Company or any
other officer or director of the Company currently owns any interest in
Upstream.

    The Company has granted to Jerry F. Holditch, Vice President-Exploration
and a director of the Company, a 1.5% of 8/8ths overriding royalty interest in
all leases acquired either directly or indirectly by the Company or its
affiliates in Webb County and Zapata County, Texas. See "Management--Overriding
Royalty Interests."

    On June 10, 1997, Glenn D. Hart, Chairman of the Board and Chief Executive
Officer of the Company, entered into an agreement with the Company pursuant to
which Mr. Hart granted the Company an option to purchase an undivided
two-thirds working interest, which Mr. Hart owns in his individual capacity, in
a leasehold interest. The leasehold interest expires on May 30, 2000 and covers
approximately 750 acres in Webb County, Texas. The exercise price of the option
is $87,500. In addition, pursuant to the agreement, if the purchase option is
exercised, Mr. Hart will be entitled to reserve a 1% overriding royalty
interest. As additional consideration for the option, pursuant to the agreement
the Company has agreed to pay to Mr. Hart for so long as the purchase option
remains unexercised (i) on a monthly basis, an amount equal to one-twelfth of
the sum of the prime interest rate as published by Comerica Bank from time to
time plus 2%, multiplied by $87,500, and (ii) all rental payments due during
the primary term of the lease.

    Concurrently with the closing of the sale of the Old Notes, the Company
acquired, for a purchase price of $11.0 million, the Net Profits Interest from
Cambrian, at which time Cambrian received a warrant to acquire 38,671 shares of
Common Stock at an exercise price of $8.00 per share. See "Use of Proceeds,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Financing Arrangements" and "Description of Capital
Stock--Warrants."

    From May to July of 1995, the Company made loans to Mr. Hart, Chairman of
the Board and Chief Executive Officer of the Company, in an aggregate principal
amount of $314,700. Mr. Hart used the proceeds for unrelated investments.
Interest on the indebtedness accrued at a rate of 5% per annum. Mr. Hart repaid
$302,055 of such indebtedness to the Company in December 1995 and repaid the
balance, together with interest, in May 1997. The maximum amount of such loans
outstanding during 1995, 1996 and 1997 was $314,700, $20,034 and $20,242,
respectively.

    In September 1995, the Company distributed its equity interest in two non
energy-related limited liability companies to the shareholders of the Company.
See Note 7 of Notes to  Financial Statements of the Company.
    

    During the year ended December 31, 1995, the Company distributed its
overriding royalty interests in certain oil and natural gas properties to the
shareholders of the Company. The distribution was recorded at the book value of
$60,000.  See Note 8 of Notes to  Financial Statements of the Company.

    Bryant Patton, a director of MHI and the Company, is a vice president of
Associated Energy Managers, which facilitated a loan in 1991 from Endowment
Energy Partners, L.P. to the Company in the original principal amount of
approximately $7.0 million. The loan was paid in full in 1996 with the proceeds
of the T.E.P. Financing.

    Although the Company has no present intention to do so, it may in the
future enter into other transactions and agreements incidental to its business
with its directors, officers and principal shareholders. The Company intends
any such transactions and agreements to be on terms no less favorable to the
Company than could be obtained from unaffiliated parties on an arms' length
basis.

                              DESCRIPTION OF NOTES

    The Old Notes were, and the New Notes will be, issued pursuant to the
Indenture dated April 2, 1998 (the "Indenture"), between the Company and State
Street Bank and Trust Company, as trustee (the "Trustee"). The terms of the New
Notes are identical in all material respects to the Old Notes, except that the
New Notes have been registered under the Securities Act and, therefore, will
not bear legends restricting their transfer.  Upon the issuance of the New
Notes, the Indenture will be subject to the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"). The New Notes are subject to the
Indenture, and Holders of the Old Notes and New Notes are referred to the
Indenture and the Trust Indenture Act.  The following summary of the material
provisions of the Indenture does not purport to be complete and is qualified in
its entirety by reference to the Indenture, including the definitions therein
of certain terms used below. Copies of the Indenture are made available to
prospective investors as set forth under the caption "--Additional
Information." The definitions of certain terms used in the following summary
are set forth below under the caption "--Certain Definitions."

GENERAL

    The aggregate principal amount of the Old Notes is, and the New Notes will
be, limited to $135.0 million. Each New Note will mature on April 1, 2005 and
will bear interest at an annual rate of 11  1/2% per annum from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of original issuance, payable semiannually in arrears on April 1 and
October 1 of each year, commencing October 1, 1998, to the Person in whose name
the New Note is registered at the close of business on March 15 or September 15
preceding such interest payment date.  Interest will be computed on the basis
of a 360-day year of twelve 30-day months. Liquidated Damages also will be
payable on the New Notes if the Company fails to satisfy certain requirements
set forth in the Registration Rights Agreement.  Principal of, and premium, if
any, interest and Liquidated Damages, if any, on the New Notes will be payable
at the office or agency maintained for such purpose within New York City, New
York, or at the option of the Company, payment of interest and Liquidated
Damages, if any, may be made by check mailed to the Holders of the New Notes at
their respective addresses set forth in the register of Holders of the New
Notes; provided that all payments of principal, premium, interest and
Liquidated Damages, if any, with respect to the New Notes, the Holders of which
have given wire transfer instructions to the Company, will be required to be
made by wire transfer of immediately available funds to the accounts specified
by the Holders thereof. Until otherwise designated by the Company, the
Company's office or agency in New York City will be the office of the Trustee
maintained for such purpose. The New Notes will be issued in denominations of
$1,000 and integral multiples thereof.

    Under certain circumstances, the Company will be able to designate its
Subsidiaries as Unrestricted Subsidiaries.  Unrestricted Subsidiaries will not
be subject to most of the restrictive covenants set forth in the Indenture. As
of the date of the Indenture, the Company had no Subsidiaries.

RANKING

    The Old Notes are, and the New Notes will be, general senior unsecured
obligations of the Company. The Old Notes rank, and the New Notes will rank,
pari passu with all existing and future Senior Indebtedness of the Company and
senior in right of payment to all future Subordinated Indebtedness of the
Company. Holders of secured Indebtedness of the Company and its Subsidiaries,
including under the Credit Facility, have and will have claims with respect to
assets constituting collateral for such Indebtedness that are prior to the
claims of the Holders of the New Notes. To the extent of such pledged
collateral, such Indebtedness will have priority over the New Notes. As of
December 31, 1997, on a pro forma basis after giving effect to the sale of the
Old Notes, the application of the net proceeds therefrom, the exchange of the
Old Notes for New Notes and the Transactions, the Company would have had no
secured Indebtedness and no Indebtedness other than the Notes. There is
currently no Indebtedness of the Company which would constitute Subordinated
Indebtedness.

GUARANTEES

    The Old Notes are, and the New Notes will be, jointly and severally
unconditionally guaranteed by each of the Company's future Restricted
Subsidiaries. As of the date of the Indenture, the Company had no Subsidiaries.
The Indenture provides that each Person that is or becomes a Restricted
Subsidiary on or after the Issue Date will jointly and severally guarantee the
payment of the Note Obligations in the manner described herein. Each Guarantor
will guarantee to each Holder and the Trustee, the full and prompt performance
of the Note Obligations of the Company, including the payment of principal of
(premium, if any, on) and interest and Liquidated Damages, if any, on the Notes
pursuant to its Guarantee. The Obligations of each Guarantor under its
Guarantee will be general senior unsecured obligations of such Guarantor, which
will rank pari passu with all existing and future Senior Indebtedness of such
Guarantor and senior in right of payment to all future Subordinated
Indebtedness of such Guarantor.





                                      -52-
<PAGE>   57
    The Obligations of each Guarantor under its Guarantee are limited to the
amount as will, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from
or payments made by or on behalf of any other Restricted Subsidiaries that
become Guarantors in respect of the Obligations of such other Restricted
Subsidiary under its Guarantee or pursuant to its contribution Obligations
under the Indenture, result in the Obligations of the Guarantor under its
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
federal, state or foreign law. In the event of additional guarantors, a
Guarantor that makes a payment or distribution under a Guarantee shall be
entitled to a contribution from each other Restricted Subsidiary that has
become a Guarantor in a pro rata amount based on the Adjusted Net Assets of the
Guarantor.

    The Indenture provides that, subject to the following paragraph, no
Guarantor (including any existing or future Restricted Subsidiary that becomes
an additional Guarantor) may consolidate with or merge with or into (whether or
not such Guarantor is the surviving Person) another Person (whether or not
affiliated with such Guarantor) unless (i) the Person formed by or surviving
any such consolidation or merger (if other than such Guarantor) is a
corporation organized and existing under the laws of the United States of
America, any state thereof, or the District of Columbia and expressly assumes
all the obligations of such Guarantor pursuant to a supplemental indenture, in
a form reasonably satisfactory to the Trustee, under the Notes, the Indenture
and the Registration Rights Agreement, (ii) immediately before and after giving
effect to such transaction, no Default or Event of Default exists, (iii) the
Guarantor or the Person formed by or surviving any such consolidation or merger
on a pro forma basis will have Consolidated Net Worth (immediately after the
transaction) equal to or greater than the Consolidated Net Worth of such
Guarantor immediately preceding the transaction and (iv) the Company will, at
the time of such transaction after giving pro forma effect thereto as if such
transaction had occurred at the beginning of the applicable Reference Period,
be permitted to incur at least $1.00 of additional Indebtedness as described in
the first paragraph under "--Certain Covenants--Limitation on Incurrence of
Additional Indebtedness"; provided that the merger of any Guarantor with or
into the Company or another Guarantor under circumstances where the Company or
such Guarantor, as applicable, is the surviving Person shall not be subject to
the foregoing provisions.

    The Indenture provides that in the event of a sale or other disposition of
all or substantially all of the assets of any Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the
Capital Stock of any Guarantor, then the Guarantor (in the event of a sale or
other disposition, by way of such a merger, consolidation or otherwise, of all
of the Capital Stock of such Guarantor) or the corporation acquiring the
property (in the event of a sale or other disposition of all or substantially
all of the assets of such Guarantor) will be released and relieved of any
obligations under its Guarantee; provided that the Net Cash Proceeds of such
sale or other disposition are applied in accordance with the provisions of the
Indenture described under "--Certain Covenants --Limitation on Sale of Assets."

OPTIONAL REDEMPTION

    The Old Notes are not, and the New Notes will not be, redeemable at the
Company's option prior to April 1, 2003.  Thereafter, the Old Notes are, and
the New Notes will be, subject to redemption at any time at the option of the
Company, in whole or part, upon not less than 30 nor more than 60 days' notice,
at the redemption prices (expressed as percentages of the principal amount of
the Notes) set forth below, plus, in each case, accrued and unpaid interest and
Liquidated Damages, if any, thereon to the applicable redemption date, if
redeemed during the 12-month period beginning on April 1 of the years indicated

outstanding immediately after the occurrence of each such redemption and (ii)
each such redemption shall occur within 90 days after the date of the closing

SELECTION AND NOTICE

    If less than all of the New Notes are to be redeemed at any time, selection
of New Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the New Notes are listed, or if the New Notes are not so listed, on a pro rata
basis, by lot or by any other method that the Trustee considers fair and
appropriate; provided that no New Notes with a principal amount of $1,000 or
less will be redeemed in part. Notice of redemption will be mailed by first
class mail at least 30 but not more than 60 days before the date fixed for
redemption to each Holder of New Notes to be redeemed at its registered
address. Notices of redemption may not be conditional. If any New Note is to be
redeemed in part only, the notice of redemption that relates to such New Note
will state the portion of the principal amount thereof to be redeemed. A new
New Note in a principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original New
Note. New Notes called for redemption become due on the date fixed for
redemption. On and after the date fixed for the redemption date, interest and
Liquidated Damages, if any, cease to accrue on New Notes or portions called for
redemption.

MANDATORY REDEMPTION

    Except as set forth below under the captions "--Change of Control," and
"--Certain Covenants--Limitation on Sale of Assets," the Company is not
required to make mandatory redemption or sinking fund payments with respect to
the Old Notes, nor will it be required to do so with respect to the New Notes.

CHANGE OF CONTROL

   
    The Indenture provides that, upon the occurrence of any Change of Control,
the Company will offer (a "Change of Control Offer") to repurchase all
outstanding Notes at a purchase price equal to 101% of the aggregate principal
amount of the Notes, plus accrued and unpaid interest and Liquidated Damages, if
any, thereon to the date fixed for repurchase (the "Change of Control Payment").
The obligation of the Company to offer to repurchase the New Notes upon a Change
of Control may not be waived by the Company, Board of Directors or Trustees
without the written consent of at least a majority in principal amount of the
then outstanding New Notes. See "-Modification and Waiver". Within 10 business
days following a Change of Control, the Company will mail a notice to each
Holder describing the transaction or transactions that constitute the Change of
Control and offer to repurchase Notes on the date specified in such notice,
which date shall be no earlier than 30 days and no later than 60 days from the
date such notice is mailed (the "Change of Control Payment Date"), pursuant to
the procedures required by the Indenture and described in such notice. The
Change of Control Offer will be deemed to have commenced upon mailing of a
notice pursuant to the Indenture and will terminate 20 business days after its
commencement, unless a longer offering period is required by law. Promptly after
the termination of the Change of Control Offer, the Company will repurchase and
mail or deliver payment for all Notes tendered in response to the Change of
Control Offer.
    

    On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment Notes or portions thereof tendered pursuant to
the Change of Control Offer, (ii) deposit with the paying agent an amount equal
to the Change of Control Payment in respect of all Notes or portions thereof so
tendered and (iii) deliver to the Trustee the Notes so accepted together with
an officers' certificate stating the aggregate principal amount of the Notes or
portions thereof being purchased by the Company. The paying agent will promptly
mail to each Holder of the Notes so accepted payment in an amount equal to the
repurchase price for such Notes, and the Trustee will promptly authenticate and
mail (or cause to be transferred by book entry) to each Holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if
any; provided, that each such Note will be in a principal amount of $1,000 or
an integral multiple thereof.

    The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as
described above with respect to a Change of Control, the Indenture does not
contain provisions that permit the Holders of the Notes to require the Company
to repurchase or redeem the Notes in the event of a takeover, recapitalization
or similar transaction.

 
   
    "Change of Control" means the occurrence of any of the following: (i) the
sale, lease or transfer, in one or a series of related transactions, of all or
substantially all (under New York common law, the definition of "all or
substantially all" is determined by whether such sale, lease or transfer is made
in the usual or regular course of the business actually conducted by the
Company) of MHI's assets or the Company's assets, in either case, to any Person
or group (as such term is used in Section 13(d)(3) of the Exchange Act); (ii)
the adoption of a plan relating to the liquidation or dissolution of MHI or the
Company; (iii) the acquisition, directly or indirectly, by any Person or group
(as such term is used in Section 13(d)(3) of the Exchange Act) of beneficial
ownership (as defined in Rule 13d-3 under the Exchange Act) of more than 50% of
the aggregate voting power of the Voting Stock of MHI or the Company (for the
purposes of this definition, such other Person shall be deemed to beneficially
own any Voting Stock of a specified corporation held by a parent corporation, if
such other Person is the beneficial owner (as defined above), directly or
indirectly, of more than 35% of the voting power of the Voting Stock of such
parent corporation); or (iv) during any period of two consecutive years,
individuals who at the beginning of such period constituted the Board of
Directors of MHI or the Company (together with any new directors whose election
by such
    





                                      -54-
<PAGE>   59
Board of Directors or whose nomination for election by the shareholders of MHI
or the Company, as the case may be, was approved by a vote of 66 2/3% of the
directors of MHI or the Company, as the case may be, then still in office who
were either directors at the beginning of such period or whose election or
nomination for election was previously so approved) cease for any reason to
constitute a majority of the Board of Directors of MHI or the Company, as the
case may be, then in office.

    The Company will comply with Section 14 of the Exchange Act and the
provisions of Regulation 14E and any other tender offer rules under the
Exchange Act and any other federal and state securities laws, rules and
regulations which may then be applicable to any Change of Control Offer.

   
    Certain terms of the Credit Facility may prohibit the Company from
purchasing any Notes following a Change of Control and provide that certain
change of control events with respect to the Company would constitute a default
thereunder. In the event a Change of Control occurs at a time when the Company
is prohibited from purchasing any Notes, the Company could seek the consent of
such lenders to the purchase of any Notes or could attempt to refinance the
indebtedness that contains such prohibition. If the Company does not obtain such
a consent or repay such indebtedness, the Company will remain prohibited from
purchasing any Notes. The Company's failure to offer to purchase the Notes, or
to purchase tendered Notes, following a Change of Control would constitute an
Event of Default under the Indenture which, in turn, will constitute a default
under the Credit Facility.
    

    The Company will not be required to make a Change of Control Offer
following a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in the Indenture applicable to a Change of Control Offer
made by the Company and purchases all Notes validly tendered and not withdrawn
under such Change of Control.

CERTAIN COVENANTS

    Limitation on Incurrence of Additional Indebtedness. The Indenture provides
that the Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, issue, incur, assume, guarantee,
become liable, contingently or otherwise, with respect to or otherwise become
responsible for the payment of (collectively, "incur") any Indebtedness (other
than Permitted Indebtedness); provided, however, that if no Default or Event of
Default shall have occurred and be continuing at the time or as a consequence
of the incurrence of such Indebtedness, the Company or its Restricted
Subsidiaries may incur Indebtedness if, on a pro forma basis, after giving
effect to such incurrence and the application of the proceeds therefrom, both
of the following tests shall have been satisfied: (i) the Consolidated Interest
Coverage Ratio for the last four fiscal quarter Reference Period immediately
preceding the incurrence of such Indebtedness is at least (a) 2.25-to-1.0 with
respect to any date of incurrence of additional Indebtedness occurring on or
before the first anniversary date of the Issue Date, (b) 2.50-to-1.0 with
respect to any date of incurrence of additional Indebtedness occurring after
the first anniversary date of the Issue Date and on or before October 1, 2000,
or (c) 2.75-to-1.0 with respect to any date of incurrence of additional
Indebtedness occurring after October 1, 2000 and (ii) Adjusted Consolidated Net
Tangible Assets would have been equal to or greater than 150% of Indebtedness
of the Company and its Restricted Subsidiaries.

    Notwithstanding the foregoing, if no Default or Event of Default shall have
occurred and be continuing at the time or as a consequence of the incurrence of
such Indebtedness, the Company and its Restricted Subsidiaries may incur
Permitted Indebtedness.

    Any Indebtedness of a Person existing at the time such Person becomes a
Restricted Subsidiary (whether by merger, consolidation, acquisition or
otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the
time it becomes a Restricted Subsidiary.

    The Indenture provides that, notwithstanding the preceding paragraphs of
this covenant, no Restricted Subsidiary that is not already a Guarantor shall,
directly or indirectly, incur Indebtedness on its behalf or Indebtedness with
respect to any Indebtedness of the Company or any other Restricted Subsidiary
unless such Restricted Subsidiary, the Company and the Trustee execute and
deliver a supplemental indenture to evidence such Restricted Subsidiary's
Guarantee of the Notes and such Restricted Subsidiary and the Company execute
and deliver or cause to be executed and delivered such other instruments and
actions required in connection therewith as provided in the Indenture.

    Limitation on Restricted Payments. The Indenture provides that the Company
will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly, make any Restricted Payment, unless:





                                      -55-
<PAGE>   60
    (i) no Default or Event of Default shall have occurred and be continuing at
the time of or immediately after giving effect to such Restricted Payment;

    (ii) at the time of and immediately after giving pro forma effect to such
Restricted Payment as if it had been made at the beginning of the applicable
four-quarter period, the Company would have been permitted to incur at least
$1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant
to the first paragraph of the covenant captioned "--Limitation on Incurrence of
Additional Indebtedness"; and

    (iii) immediately after giving effect to such Restricted Payment, the
aggregate of all Restricted Payments declared or made after the Issue Date does
not exceed the sum of

          (A) 50% of the Consolidated Net Income of the Company and its
    Restricted Subsidiaries (or in the event such Consolidated Net Income shall
    be a deficit, minus 100% of such deficit) during the period (treated as one
    accounting period) subsequent to March 31, 1998 and ending on the last day
    of the fiscal quarter for which financial information is available
    immediately preceding the date of such Restricted Payment (less the
    aggregate amount of dividends described in clause (i) of the following full
    paragraph that are either (x) paid after the last day of the fiscal quarter
    for which financial information is available immediately preceding the date
    of such Restricted Payment or (y) declared but not yet paid as of such
    date);

          (B) the aggregate Net Cash Proceeds received by the Company during
    such period from any Person other than a Subsidiary of the Company as a
    result of the issuance or sale of Capital Stock of the Company (other than
    any Disqualified Stock), other than in connection with the conversion of
    Indebtedness or Disqualified Stock;

          (C) the aggregate Net Cash Proceeds received by the Company during
    such period from any Person other than a Subsidiary of the Company as a
    result of the issuance or sale of any Indebtedness or Disqualified Stock to
    the extent that, at the time the determination is made, such Indebtedness
    or Disqualified Stock, as the case may be, has been converted into or
    exchanged for Capital Stock of the Company (other than Disqualified Stock);

          (D) (i) in case any Unrestricted Subsidiary has been redesignated a
    Restricted Subsidiary, an amount equal to the lesser of (x) the book value
    (determined in accordance with GAAP) at the date of such redesignation of
    the aggregate Investments made by the Company and its Restricted
    Subsidiaries in such Unrestricted Subsidiary and (y) the fair market value
    of such Investments in such Unrestricted Subsidiary at the time of such
    redesignation, as determined in good faith by the Company's Board of
    Directors, including a majority of the Company's Disinterested Directors,
    whose determination shall be conclusive and evidenced by a resolution of
    such Board (less, in the case of each of clauses (x) and (y), the amount of
    original Investment (based upon book value determined in accordance with
    GAAP at the time of such Investment) made by the Company or any Restricted
    Subsidiary pursuant to clause (x) of the definition of "Permitted Business
    Investment" minus the aggregate cash dividends paid by such Unrestricted
    Subsidiary to the Company or any other Restricted Subsidiary since the date
    of such original Investment, provided that the result of the foregoing
    shall not be less than zero); or (ii) in case any Restricted Subsidiary has
    been redesignated an Unrestricted Subsidiary, minus the greater of (x) the
    book value (determined in accordance with GAAP) at the date of
    redesignation of the aggregate Investments made by the Company and its
    Restricted Subsidiaries and (y) the fair market value of such Investments
    in such Restricted Subsidiary at the time of such redesignation, as
    determined in good faith by the Company's Board of Directors, including a
    majority of the Company's Disinterested Directors, whose determination
    shall be conclusive and evidenced by a resolution of such Board; and

          (E) the amount of any writedowns or writeoffs, other negative
    revaluations and other negative extraordinary charges not otherwise
    reflected in Consolidated Net Income of the Company during such period.

    Notwithstanding the foregoing, the above limitations will not prevent (i)
the payment of any dividend within 60 days after the date of declaration
thereof, if at such date of declaration, such payment complied with the
provisions of the Indenture; (ii) any dividend on shares of Capital Stock of
the Company or any Restricted Subsidiary payable solely in shares of Capital
Stock (other than Disqualified Stock); (iii) any dividend or other distribution
payable from a Subsidiary of the Company to the Company or any Wholly Owned
Restricted Subsidiary; (iv) the repurchase, redemption or other acquisition or
retirement of any shares of any class of Capital Stock of the Company or any
Restricted Subsidiary, in exchange for, or out of the aggregate Net Cash
Proceeds of a substantially concurrent issue and sale (other than to a
Restricted Subsidiary) of shares of Capital Stock of the Company (other than
Disqualified Stock), provided that the Net Cash Proceeds expended or utilized
for such repurchase, redemption or other acquisition or retirement shall not be
included in subclause (B) of clause (iii) of the preceding full paragraph; and
(v) the repurchase, redemption or other acquisition or retirement for value of
Capital Stock of MHI held by a departing or deceased shareholder of Capital
Stock of MHI pursuant to MHI's shareholders' agreement, provided that the funds
or value expended or incurred, or committed to be expended or incurred, in each
fiscal year of the Company does





                                      -56-
<PAGE>   61
not exceed in the aggregate $500,000 and no Default or Event of Default shall
have occurred and be continuing immediately after any such repurchase,
redemption or acquisition or retirement.

    The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any non-cash Restricted Payment shall be determined in
good faith by the Board of Directors of the Company, whose resolution in
respect thereto shall be delivered to the Trustee (which shall certify that
such valuation has been approved by a majority of the Disinterested Directors).
Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an officers' certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the covenant "Limitation on Restricted Payments" were computed.

    Limitation on Sale of Assets. The Indenture provides that the Company will
not, and will not permit any Restricted Subsidiary to, directly or indirectly,
make any Asset Sale unless:

    (i) the Company (or its Restricted Subsidiary, as the case may be) receives
consideration at the time of such sale or other disposition at least equal to
the fair market value thereof (as determined in good faith by the Company,
which determination, with respect to Asset Sales or series of related Asset
Sales with proceeds valued at greater than $5.0 million, shall be evidenced by
a resolution duly adopted by the Company's Board of Directors, including a
majority of the Company's Disinterested Directors);

    (ii) at least 75% of the proceeds from such Asset Sale consist of cash or
U.S. dollar denominated Cash Equivalents; and

    (iii) the Net Cash Proceeds received by the Company (or its Restricted
Subsidiary, as the case may be) from such Asset Sale are applied in accordance
with the following two paragraphs.

    The Company may apply such Net Cash Proceeds, within 365 days after receipt
of Net Cash Proceeds from any Asset Sale, to: (a) the repayment of Indebtedness
of the Company under a Bank Credit Facility or other Senior Indebtedness of the
Company or Senior Indebtedness of a Guarantor, that results in a permanent
reduction in any revolving credit or other commitment relating thereto or the
maximum principal amount that may be borrowed thereunder in an amount equal to
the principal amount so repaid; (b) make an Investment in assets used in the
Oil and Gas Business in replacement of the assets that were the subject of the
Asset Sale giving rise to such Net Cash Proceeds; or (c) develop by drilling,
completing and producing reserves from the oil and gas properties of the
Company and the Restricted Subsidiaries.

    If, at the end of the 365-day period, the Net Cash Proceeds of any Asset
Sale less the aggregate amount applied by the Company during such period as
described in clauses (a), (b) and (c) in the immediately preceding paragraph,
together with any Net Cash Proceeds in excess of amounts similarly applied by
the Company from any prior Asset Sale after the date of receipt of such Net
Cash Proceeds (such aggregate constituting "Excess Proceeds"), exceeds $5.0
million, then the Company will be obligated to make an offer (the "Net Proceeds
Offer") to repurchase the Notes (and any other Senior Indebtedness in respect
of which such an offer to repurchase also is required to be made concurrently
with the Net Proceeds Offer) having an aggregate principal amount equal to the
Excess Proceeds (such purchase to be made on a pro rata basis if the amount
available for such repurchase is less than the principal amount of the Notes
and other Senior Indebtedness tendered in such Net Proceeds Offer) at a
repurchase price of 100% of the principal amount thereof plus accrued interest
and Liquidated Damages, if any, to the date of repurchase. To the extent that
the aggregate principal amount of Notes tendered pursuant to a Net Proceeds
Offer and of such other Senior Indebtedness is less than the amount that the
Company is required to repurchase, then the Company may use any remaining
Excess Proceeds for its and its Restricted Subsidiaries' general corporate
purposes. Upon the completion of the Net Proceeds Offer, the amount of Excess
Proceeds will be reset to zero.

    Any Net Proceeds Offer will be conducted in substantially the same manner
as a Change of Control Offer. The Company will comply with Section 14 of the
Exchange Act and the provisions of Regulation 14E and any other tender offer
rules under the Exchange Act and any other federal and state securities laws,
rules and regulations which may then be applicable to any Net Proceeds Offer.

    During the period between any Asset Sale and the application of the Net
Cash Proceeds therefrom in accordance with this covenant, all Net Cash Proceeds
shall be either (i) maintained in a segregated account and shall be invested in
Permitted Financial Investments or (ii) applied to temporarily reduce
borrowings under any revolving credit facility constituting Senior Indebtedness
of the Company or Senior Indebtedness of a Guarantor.





                                      -57-
<PAGE>   62
    Notwithstanding the foregoing, the Company will not and will not permit any
Restricted Subsidiary to, directly or indirectly, make any Asset Sale of any of
the Capital Stock of a Restricted Subsidiary except pursuant to an Asset Sale
of all of the Capital Stock of such Restricted Subsidiary.

    Limitation on Liens Securing Indebtedness. The Indenture provides that the
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, create, incur, assume or suffer to exist any Liens
(other than Permitted Liens) upon any of their respective properties to secure
(i) any Indebtedness or trade payable of the Company, unless the Notes are
equally and ratably secured or (ii) any Indebtedness or trade payable of any
Guarantor, unless the Guarantees are equally and ratably secured; provided,
that if such Indebtedness is expressly subordinated to the Notes or the
Guarantees, the Lien securing such Indebtedness will be subordinated and junior
to any Lien securing the Notes or the Guarantees, with the same relative
priority as such Subordinated Indebtedness of the Company or Subordinated
Indebtedness of a Guarantor will have with respect to the Notes or the
Guarantees, as the case may be.

    Limitation on Mergers and Consolidations. The Indenture provides that the
Company will not consolidate with or merge with any Person or convey, transfer
or lease all or substantially all of its assets to any Person, unless: (i) the
Company survives such merger or the Person formed by such consolidation or into
which the Company is merged or that acquires by conveyance or transfer, or
which leases, all or substantially all of the assets of the Company is a
corporation organized and existing under the laws of the United States of
America, any state thereof or the District of Columbia and expressly assumes,
by supplemental indenture, the due and punctual payment of the principal of,
premium, if any, and interest and Liquidated Damages, if any, on all the Notes
and the performance of every other covenant and obligation of the Company under
the Indenture; (ii) immediately before and after giving effect to such
transaction, no Default or Event of Default exists; (iii) immediately after
giving effect to such transaction on a pro forma basis, the Consolidated Net
Worth of the Company (or the surviving or transferee entity) is equal to or
greater than the Consolidated Net Worth of the Company immediately before such
transaction; and (iv) immediately after giving effect to such transaction on a
pro forma basis as if such transaction had occurred at the beginning of the
applicable four- quarter period, the Company (or the surviving or transferee
entity) would be permitted to incur at least $1.00 of additional Indebtedness
(other than Permitted Indebtedness) pursuant to the first paragraph of the
covenant captioned "--Certain Covenants--Limitation on Incurrence of Additional
Indebtedness." Upon any such consolidation, merger, lease, conveyance or
transfer in accordance with the foregoing, the successor Person formed by such
consolidation or into which the Company is merged or to which such lease,
conveyance or transfer is made shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under the Indenture with the
same effect as if such successor had been named as the Company herein, and
thereafter the predecessor Company will, except in the case of a lease or a
transfer pursuant to a Production Payment, be relieved of all further
obligations and covenants under the Indenture and the Notes.

    Limitation on Sale/Leaseback Transactions. The Indenture provides that the
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into any Sale/Leaseback Transaction unless (i)
the Company or such Restricted Subsidiary, as the case may be, could have (a)
incurred Indebtedness in an amount equal to the Attributable Indebtedness
relating to such Sale/Leaseback Transaction pursuant to the first paragraph of
the covenant captioned "--Limitation on Incurrence of Additional Indebtedness"
and (b) incurred a Lien to secure such Indebtedness, without being required to
equally and ratably secure the Notes pursuant to the covenant described under
the caption "--Limitation on Liens Securing Indebtedness", and (ii) the Company
or such Restricted Subsidiary receives gross proceeds from such Sale/Leaseback
Transaction at least equal to the fair market value thereof (as determined in
good faith by the Company's Board of Directors, whose determination in good
faith, evidenced by a resolution of such Board, shall be conclusive) and the
transfer of assets in such Sale/Leaseback Transaction is permitted by, and the
proceeds of such transaction are applied in compliance with, the covenant
described above under the caption "--Limitation on Sale of Assets".

    Limitation on Payment Restrictions Affecting Subsidiaries. The Indenture
provides that the Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i) pay dividends or make any other distributions on
its Capital Stock or on any other interest or participation in the Company or a
Restricted Subsidiary; (ii) pay any indebtedness owed to the Company or a
Restricted Subsidiary of the Company; (iii) make loans or advances to the
Company or a Restricted Subsidiary of the Company; or (iv) transfer any of its
properties or assets to the Company or a Restricted Subsidiary of the Company
(each, a "Payment Restriction"), except for (a) encumbrances or restrictions
under a Bank Credit Facility; provided, that no encumbrance or restriction
shall limit the ability of any Restricted Subsidiary to transfer cash to the
Company except upon the occurrence of an event of default under the Bank Credit
Facility; (b) consensual encumbrances or consensual restrictions binding upon
any Person at the time such Person becomes a Restricted Subsidiary of the
Company (unless the agreement creating such consensual encumbrances or
consensual restrictions was entered into in connection with, or in
contemplation of, such entity becoming a Restricted Subsidiary); (c) consensual
encumbrances





                                      -58-
<PAGE>   63
or consensual restrictions under any agreement that refinances or replaces any
agreement described in clauses (a) and (b) above, provided that the terms and
conditions of any such restrictions are, in the aggregate, no less favorable to
the Holders of the Notes than those under the agreement so refinanced or
replaced; and (d) customary non-assignment provisions in leases, purchase money
financings and any encumbrance or restriction due to applicable law.

    Limitation on Issuances and Sales of Restricted Subsidiary Stock. The
Indenture provides that the Company (i) will not permit any Restricted
Subsidiary, directly or indirectly, to issue any Disqualified Stock or
Preferred Stock (other than to the Company or a Restricted Subsidiary) and (ii)
will not permit any Person (other than (y) the Company and/or one or more
Restricted Subsidiaries or (z) MHI, indirectly through its direct ownership of
the Capital Stock of the Company), directly or indirectly, to own any Capital
Stock of any Restricted Subsidiary; provided, however, that this covenant shall
not prohibit (a) the issuance or sale of all, but not less than all, of the
issued and outstanding Capital Stock of any Restricted Subsidiary owned by the
Company or any of its Restricted Subsidiaries in compliance with the other
provisions of the Indenture, (b) the issuance or sale of (A) not more than 5%
in the aggregate of the issued and outstanding Capital Stock of any Restricted
Subsidiary (calculated on a fully diluted basis) by the Company or any
Restricted Subsidiary or (B) more than 5% of the issued and outstanding Capital
Stock of any Restricted Subsidiary if immediately following such issuance and
sale (calculated on a fully diluted basis) the Company and all Subsidiaries
will collectively own 95% or more of the Consolidated Total Assets of the
Company, and in the case of either (A) or (B), immediately following such
issuance and sale, the Company or one or more Restricted Subsidiaries will
collectively hold the voting power to elect a majority of the directors of the
Restricted Subsidiary and such power is not subject to dilution or limitation
by the terms of such Capital Stock, by agreement, by passage of time or the
occurrence of any future event or (c) the ownership by directors of directors'
qualifying shares or the ownership by foreign governments or foreign nationals
of Capital Stock of any Restricted Subsidiary, to the extent mandated by
applicable law, and in each case, so long as such Restricted Subsidiary
constitutes a Wholly Owned Restricted Subsidiary.

    Limitation on Transactions with Affiliates. The Indenture provides that the
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into any transaction or series of transactions
(including, without limitation, the sale, purchase, transfer, lease or other
disposition of any assets or properties or the rendering of any services or the
entry into any contract, agreement or arrangement (whether in writing or
otherwise)) with any Affiliate or beneficial owner (as defined in Rules 13d-3
and 13d-5 under the Exchange Act) of 10% or more of the Company's common stock
(other than with a Wholly Owned Restricted Subsidiary of the Company) (an
"Affiliate Transaction"), on terms that are less favorable to the Company or
such Restricted Subsidiary, as the case may be, than would be available on an
arm's-length basis in a comparable transaction with an unrelated Person. In
addition, the Company will not, and will not permit any Restricted Subsidiary
of the Company to, directly or indirectly, enter into an Affiliate Transaction,
or any series of related Affiliate Transactions having a value of (i) more than
$1.0 million, unless a majority of the Board of Directors of the Company
(including a majority of the Company's Disinterested Directors) determines in
good faith, as evidenced by a resolution of such Board, that such Affiliate
Transaction or series of related Affiliate Transactions is fair to the Company
and in compliance with the first sentence of this covenant; or (ii) more than
$10.0 million, unless the Company receives a written opinion from a nationally
recognized investment banking firm that such transaction or series of
transactions is fair to the Company from a financial point of view.

    Limitation on Line of Business. The Indenture provides that the Company and
the Subsidiaries will be operated in a manner such that their business
activities will be the Oil and Gas Business or an Investment in a business or
Person engaged in the Oil and Gas Business, which Investment was not made in
violation of any provision of the Indenture.

    SEC Reports. The Indenture provides that notwithstanding that the Company
may not be required to remain subject to the reporting requirements of Section
13 or 15(d) of the Exchange Act, the Company will file with the SEC (if the SEC
will so accept) and provide the Trustee and Holders with annual reports and
such information, documents and other reports specified in Sections 13 and
15(d) of the Exchange Act.

    Future Designation of Restricted and Unrestricted Subsidiaries. The
foregoing covenants (including calculation of financial ratios and the
determination of limitations on the incurrence of Indebtedness and Liens) may
be affected by the designation by the Company of any of its Subsidiaries as an
Unrestricted Subsidiary. Generally, a Restricted Subsidiary includes any
Subsidiary of the Company, whether existing on or after the date of the
Indenture, unless the Subsidiary of the Company is designated as an
Unrestricted Subsidiary pursuant to the terms of the Indenture. The definition
of "Unrestricted Subsidiary" set forth under the caption "--Certain
Definitions" describes the circumstances under which a future Subsidiary of the
Company may be designated as an Unrestricted Subsidiary by the Board of

CERTAIN DEFINITIONS

    The following is a summary of certain defined terms to be used in the
Indenture. Reference is made to the Indenture for the full definition of all
such terms and for the definitions of capitalized terms used herein and not
defined below.

    "Adjusted Consolidated Net Tangible Assets" or "ACNTA" means (without
duplication), as of the date of determination, (a) the sum of (i) discounted
future net revenue from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with SEC guidelines before any
state or federal income taxes, as estimated by independent petroleum engineers
in a reserve report prepared as of the end of the Company's most recently
completed fiscal year, as increased by, as of the date of determination, the
discounted future net revenue of (A) estimated proved oil and gas reserves of
the Company and its Restricted Subsidiaries attributable to any acquisition
consummated since the effective date of such initial or year-end reserve
reports and (B) estimated oil and gas reserves of the Company and its
Restricted Subsidiaries attributable to extensions, discoveries and other
additions and upward revisions of estimates of proved oil and gas reserves due
to exploration, development or exploitation, production or other activities
conducted or otherwise occurring since the effective date of such initial or
year-end reserve reports which, in the case of sub-clauses (A) and (B) above,
would, in accordance with standard industry practice, result in such increases,
in each case calculated in accordance with SEC guidelines (utilizing the prices
utilized in such initial or year-end reserve reports), and decreased by, as of
the date of determination, the discounted future net revenue of (C) estimated
proved oil and gas reserves of the Company and its Restricted Subsidiaries
produced or disposed of since the effective date of such initial or year-end
reserve reports and (D) reductions in the estimated oil and gas reserves of the
Company and its Restricted Subsidiaries since the effective date of such
initial or year-end reserve reports attributable to downward revisions of
estimates of proved oil and gas reserves due to exploration, development or
exploitation, production or other activities conducted or otherwise occurring
since the effective date of such initial or year-end reserve reports which
would, in accordance with standard industry practice, result in such revisions,
in each case calculated in accordance with SEC guidelines (utilizing the prices
utilized in such initial or year-end reserve reports); provided that, in the
case of each of the determinations made pursuant to sub-clauses (A) through (D)
above, such increases and decreases shall be as estimated by the Company's
engineers, except that if as a result of such acquisitions, dispositions,
discoveries, extensions or revisions, there is a Material Change and in
connection with the incurrence of Indebtedness under the covenant captioned
"--Certain Covenants --Limitation on Incurrence of Additional Indebtedness,"
all or any part of an increase in discounted future net revenue resulting from
the matters described in sub-clauses (A) and (B) above are needed to permit the
incurrence of such Indebtedness, then the discounted future net revenue
utilized for purposes of this clause (a)(i) shall be confirmed in writing by
independent petroleum engineers provided that, in the event that the
determinations made pursuant to sub-clauses (C) and (D) above, when taken
alone, would not cause a Material Change, then such written confirmation need
only cover the incremental additions to discounted future net revenues
resulting from the determinations made pursuant to sub-clauses (A) and (B)
above to the extent needed to permit the incurrence of such Indebtedness, (ii)
the capitalized costs that are attributable to oil and gas properties of the
Company and its Restricted Subsidiaries to which no proved oil and gas reserves
are attributed, based on the Company's books and records as of a date no
earlier than the date of the Company's latest annual or quarterly financial
statements, (iii) the Net Working Capital on a date no earlier than the date of
the Company's latest annual or quarterly financial statements and (iv) the
greater of (I) the net book value on a date no earlier than the date of the
Company's latest annual or quarterly financial statements and (II) the
appraised value, as estimated by independent appraisers, of other tangible
assets (including Investments in unconsolidated Subsidiaries of the Company) of
the Company and its Restricted Subsidiaries, as of a date no earlier than the
date of the Company's latest audited financial statements, minus (b) the sum of
(i) minority interests, (ii) any non-current portion of gas balancing
liabilities of the Company and its Restricted Subsidiaries reflected in the
Company's latest annual or quarterly financial statements, (iii) the discounted
future net revenue, calculated in accordance with SEC guidelines (utilizing the
prices utilized in the Company's initial or year-end reserve reports),
attributable to reserves which are required to be delivered to third parties to
fully satisfy the obligations of the Company and its Restricted Subsidiaries
with respect to Volumetric Production Payments on the schedules specified with
respect thereto, (iv) the discounted future net revenue, calculated in
accordance with SEC guidelines, attributable to reserves subject to
Dollar-Denominated Production Payments which, based on the estimates of
production included in determining the discounted future net revenue specified
in clause (a)(i) above (utilizing the same prices utilized in the Company's
initial or year-end reserve reports), would be necessary to fully satisfy the
payment obligations of the Company and its Restricted Subsidiaries with respect
to Dollar-Denominated Production Payments on the schedules specified with
respect thereto and (v) the discounted future net revenue, calculated in
accordance with SEC guidelines (utilizing the same prices utilized in the
Company's initial or year-end reserve reports), attributable to reserves
subject to participation interests, overriding royalty interests or other
interests of third parties, pursuant to participation, partnership, vendor
financing or other agreements then in effect, or which otherwise are required
to be delivered to third parties. If the Company changes its method of
accounting from the successful efforts method to the full cost method or a
similar method of accounting, Adjusted Consolidated Net





                                      -60-
<PAGE>   65
Tangible Assets will continue to be calculated as if the Company was still
using the successful efforts method of accounting.

    Discounted future net revenue attributable to reserves subject to
Production Payments or other third party interests are excluded from the
definition of Adjusted Consolidated Net Tangible Assets to the extent
indicated, thereby limiting the amount of Indebtedness that may be incurred
pursuant to the test set forth in clause (ii) of the first paragraph of the
covenant captioned "--Certain Covenants--Limitation on Incurrence of Additional
Indebtedness." However, certain estimated volumes of reserves in excess of the
delivery requirements under such Production Payments or with respect to
commitments to third party interests that are available for sale by the Company
are included in the definition of Adjusted Consolidated Net Tangible Assets,
thereby increasing the amount of Indebtedness that may be incurred under such
test.

    "Adjusted Net Assets" of a Guarantor at any date shall mean the lesser of
(i) the amount by which the fair value of the property of such Guarantor
exceeds the total amount of liabilities, including, without limitation,
contingent liabilities (after giving effect to all other fixed and contingent

the Guarantee of such Guarantor at such date and (ii) the amount by which the
present fair saleable value of the assets of such Guarantor at such date
exceeds the amount that will be required to pay the probable liability of such
Guarantor on its debts (after giving effect to all other fixed and contingent
liabilities incurred or assumed on such date and after giving effect to any
collection from any Subsidiary of such Guarantor in respect of the obligations
of such Subsidiary under the Guarantee), excluding debt in respect of the
Guarantee, as they become absolute and matured.

    "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,
"control" when used with respect to any specified Person means the power to
direct the management and policies of such Person directly or indirectly,
whether through the ownership of Voting Stock, by contract or otherwise; and
the terms "controlling" and "controlled" have meanings correlative to the
foregoing; provided that a corporation shall not be deemed an Affiliate of the
Company solely by reason of having a single common director with the Company
who constitutes less than a majority of the directors of either the Company and
the other corporation.

Stock of a Restricted Subsidiary (other than directors' Qualifying Shares), or
of property or assets (including the creation of Dollar-Denominated Production
Payments and Volumetric Production Payments, other than Dollar-Denominated
Production Payments and Volumetric Production Payments created or sold in
connection with the financing of, and within 30 days after, the acquisition of
the properties subject thereto) or any interests therein (each referred to for
purposes of this definition as a disposition) by the Company or any of its
Restricted Subsidiaries, including any disposition by means of a merger,
consolidation or similar transaction (other than (a) by the Company to a Wholly
Owned Restricted Subsidiary or by a Subsidiary to the Company or a Wholly Owned
Restricted Subsidiary, (b) a sale of oil, gas or other hydrocarbons or other
mineral products in the ordinary course of business of the Company's oil and
gas production operations, (c) any abandonment, farm-in, farm-out, lease and

overriding royalty interest, in each case conveyed from or burdening proved
developed or proved undeveloped reserves and (ii) any sale of hydrocarbons or
other mineral products as a result of the creation of Dollar-Denominated
Production Payments or Volumetric Production Payments, other than
Dollar-Denominated Production Payments and Volumetric Production Payments
created or sold in connection with the financing of, and within 30 days after,
the acquisition of the properties subject thereto), (d) the disposition of all
or substantially all of the assets of the Company in compliance with the
covenants captioned "--Certain Covenants --Limitation on Mergers and
Consolidations" and " --Certain Covenants--Limitation on Sale/Leaseback
Transactions," (e) the issuance by the Company of shares of its Capital Stock,

by the Company or such Restricted Subsidiary) is reasonably equivalent to the
fair market value of the properties (together with any cash or Cash
Equivalents, not to exceed 15% of such fair market value) to be received by the
Company or such Restricted Subsidiary as determined in good faith by the Board
of Directors of the Company, which determination shall be certified by a
resolution of the Board of Directors delivered to the Trustee if such fair
market value is in excess of $5.0 million, provided that if such resolution
indicates that such fair market value is in excess of $10.0 million such
resolution shall be accompanied by a written appraisal by a nationally
recognized investment banking firm or appraisal firm, in each case specializing
or having a specialty in oil and gas properties, and (ii) such exchange is
approved by a majority of Disinterested Directors of the Company, and (g) the
sale, transfer or other disposition in the ordinary course of business of oil

    (iii) default by the Company or any Guarantor in the deposit of any
optional redemption payment; or

    (iv) default by the Company or any Guarantor in the performance of the
covenants discussed under the captions "--Change of Control," "--Certain
Covenants--Limitation on Sale of Assets" and "--Certain Covenants--Limitation
on Mergers and Consolidations;" or

    (v) default by the Company or any Restricted Subsidiary in the performance
of any other covenant or agreement in the Indenture (other than those described
in clauses (i) through (iv) above) which shall not have been remedied within 30
days after written notice by the Trustee or by the Holders of at least 25% in
principal amount of the Notes then outstanding; or

    (vi) default on any other Indebtedness (other than Non-Recourse
Indebtedness) of the Company or any Subsidiary of the Company (other than an
Unrestricted Subsidiary) if either (a) such default results in the acceleration
of the maturity of any such Indebtedness having a principal amount of
$5,000,000 or more individually or, taken together with the principal amount of
any other such Indebtedness in default or the maturity of which has been so
accelerated, in the aggregate, or (b) such default results from the failure to
pay when due principal of, or premium, if any, or interest on, any such
Indebtedness, after giving effect to any applicable grace period (a "Payment
Default"), having a principal amount of $5,000,000 or more individually or,
taken together with the principal amount of any other Indebtedness under which
there has been a Payment Default, in the aggregate; or

    (vii) the commencement of proceedings, or the taking of any enforcement
action (including by way of set-off), by any holder (or its designee or assign)
of at least $5.0 million in aggregate principal amount of Indebtedness
(including any amounts owed pursuant to a judgment or order) of the Company or
any Subsidiary of the Company (other than an Unrestricted Subsidiary, provided
that neither the Company nor any Restricted Subsidiary is liable, directly or
indirectly, for such Indebtedness), after a default under such Indebtedness, to
retain in satisfaction of such Indebtedness or to collect or seize, dispose of
or apply in satisfaction of such Indebtedness, property or assets of the
Company or its Restricted Subsidiaries having a fair market value in excess of
$5.0 million individually or in the aggregate; provided that if any such
proceedings or actions are terminated or rescinded, or such Indebtedness is
repaid or settled, in each case, other than as a result of the enforcement of
any right or process pursuant to any such proceeding or action, such Event of
Default under the Indenture and any consequential acceleration of the Notes
shall be automatically rescinded, so long as (a) such rescission does not
conflict with any judgment or decree and (b) the holder of such Indebtedness
shall not have applied any such property or assets in satisfaction of such
Indebtedness; or

    (viii) the entry by a court of one or more judgments or orders for the
payment in cash or other assets of $5.0 million or more individually or in the
aggregate (net of applicable insurance coverage acknowledged in writing by the
insurance carrier) having been rendered against the Company or any Subsidiary
of the Company (other than an Unrestricted Subsidiary; provided that neither
the Company nor any Restricted Subsidiary is liable, directly or indirectly,
for such judgment or order) and such judgment or order shall continue
unsatisfied and unstayed for a period of 60 days; or

    (ix) the occurrence of certain events giving rise to ERISA liability; or

    (x) the failure of a Guarantee by a Guarantor to be in full force and
effect (other than a release of a Guarantee in accordance with the Indenture),
or the denial or disaffirmance by such entity thereof; or

    (xi) certain events involving bankruptcy, insolvency or reorganization of
the Company or any Subsidiary of the Company (other than an Unrestricted
Subsidiary).





                                      -71-
<PAGE>   76
    The Indenture provides that the Trustee may withhold notice to the Holders
of the Notes of any default (except in payment of principal of, or premium, if
any, or interest or Liquidated Damages on the Notes) if the Trustee considers
it in the interest of the Holders of the Notes to do so.

    The Indenture provides that if an Event of Default occurs and is continuing
with respect to the Indenture, the Trustee or the Holders of not less than 25%
in principal amount of the Notes outstanding may declare the principal of and
premium, if any, and accrued but unpaid interest and Liquidated Damages (if
any) on all Notes to be due and payable.  Upon such a declaration, such
principal, premium, if any, interest and Liquidated Damages (if any) will be
due and payable immediately. Notwithstanding the foregoing, if an Event of
Default relating to certain events of bankruptcy, insolvency or reorganization
of the Company or any Subsidiary of the Company occurs and is continuing, the
principal of, and premium, if any, and accrued but unpaid interest and
Liquidated Damages (if any) on all the Notes will become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holders of the Notes.  The amount due and payable on the acceleration of
any Note will be equal to 100% of the principal amount of such Note, plus
accrued interest and Liquidated Damages (if any) to the date of payment. Under
certain circumstances, the Holders of a majority in principal amount of the
outstanding Notes may rescind any such acceleration with respect to the Notes
and its consequences.

    The Indenture provides that no Holder of a Note may pursue any remedy under
the Indenture unless (i) the Trustee shall have received written notice of a
continuing Event of Default, (ii) the Trustee shall have received a request
from Holders of at least 25% in principal amount of the Notes to pursue such
remedy, (iii) the Trustee shall have been offered indemnity reasonably
satisfactory to it, (iv) the Trustee shall have failed to act for a period of
60 days after receipt of such notice, request and offer of indemnity and (v) no
direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of
the Notes; provided, however, such provision does not affect the right of a
Holder of a Note to sue for enforcement of any overdue payment thereon.

    The Holders of a majority in principal amount of the Notes then outstanding
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee under the
Indenture, subject to certain limitations specified in the Indenture. The
Indenture will require the annual filing by the Company with the Trustee of a
written statement as to compliance with the covenants contained in the
Indenture.

MODIFICATION AND WAIVER

    The Indenture provides that modifications and amendments to the Indenture
or the Notes may be made by the Company, the Guarantors and the Trustee with
the consent of the Holders of a majority in principal amount of the Notes then
outstanding; provided that no such modification or amendment may, without the
consent of the Holder of each Note then outstanding affected thereby, (i)
reduce the percentage of principal amount of Notes whose Holders must consent
to an amendment, supplement or waiver; (ii) reduce the rate or change the time
for payment of interest, including defaulted interest, or Liquidated Damages on
any Note; (iii) reduce the principal amount of any Note or change the Maturity
Date of the Notes; (iv) reduce the redemption price, including premium, if any,
payable upon redemption of any Note or change the time at which any Note may or
shall be redeemed; (v) reduce the repurchase price, including premium, if any,
payable upon the repurchase of any Note or change the time at which any Note
may or shall be repurchased; (vi) make any Note payable in money other than
that stated in the Note; (vii) impair the right to institute suit for the
enforcement of any payment of principal of, or premium, if any, or interest or
Liquidated Damages on any Note; (viii) make any change in the percentage of
principal amount of Notes necessary to waive compliance with certain provisions
of the Indenture; or (ix) waive a continuing Default or Event of Default in the
payment of principal of, premium, if any, or interest or Liquidated Damages on
the Notes. The Indenture provides that modifications and amendments of the
Indenture may be made by the Company, the Guarantors and the Trustee without
the consent of any Holders of Notes in certain limited circumstances, including
(a) to cure any ambiguity, omission, defect or inconsistency, (b) to provide
for the assumption of the Obligations of the Company or any Guarantor under the
Indenture upon the merger, consolidation or sale or other disposition of all or
substantially all of the assets of the Company or such Guarantor, (c) to
reflect the release of any Guarantor from its Guarantee, or the addition of any
Subsidiary of the Company as a Guarantor, in the manner provided in the
Indenture, (d) to comply with any requirement of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act of
1939 or (e) to make any change that would provide any additional benefit to the
Holders or that does not adversely affect the rights of any Holder of Notes in
any material respect.

    The Indenture provides that neither the Company nor any of its Subsidiaries
shall, directly or indirectly, pay or cause to be paid any consideration,
whether by way of interest, fees or otherwise, to any Holder of any Notes for
or as an inducement to any consent, waiver or amendment of any terms or
provisions of the Notes or the Indenture unless such consideration is offered
to be paid or agreed to be paid to all Holders of the Notes which so consent,
waive or agree to amend in the time period set forth in any solicitation
documents relating to such consent.





                                      -72-
<PAGE>   77
    The Indenture provides that the Holders of a majority in aggregate
principal amount of the Notes then outstanding may waive any past default under
the Indenture, except a default in the payment of principal, premium, if any,
or interest or Liquidated Damages.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

    The Company may, at its option and at any time, elect to have its
Obligations discharged with respect to the outstanding Notes ("Legal
Defeasance"). Such Legal Defeasance means that the Company will be deemed to
have paid and discharged the entire Indebtedness represented by the outstanding
Notes, except for (i) the rights of Holders of such Notes to receive payments
in respect of the principal of, premium, if any, and interest and Liquidated
Damages (if any) on such Notes when such payments are due, (ii) the Company's
obligations with respect to such Notes concerning the issuance of temporary
Notes, transfers and exchanges of Notes, replacement of mutilated, destroyed,
lost or stolen Notes, the maintenance of an office or agency where Notes may be
surrendered for transfer or exchange or presented for payment, and duties of
paying agents, (iii) the rights, powers, trusts, duties and immunities of the
Trustee, and the Company's obligations in connection therewith and (iv) the
Legal Defeasance provisions of the Indenture. In addition, the Company may, at
its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance"), and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Notes. In the event Covenant Defeasance occurs, certain events (not
including non-payment events) described under "--Events of Default" will no
longer constitute an Event of Default with respect to the Notes.

    In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee or other qualifying
Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S.
Legal Tender, U.S. Government Securities, or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm
of independent public accountants, to pay the principal of, premium, if any,
and interest and Liquidated Damages (if any) on the outstanding Notes on the
Maturity Date or on the applicable redemption date, as the case may be, of such
principal or installment of principal, premium, if any, or interest or
Liquidated Damages (if any); (ii) in the case of Legal Defeasance, the Company
must deliver to the Trustee an opinion of counsel reasonably acceptable to the
Trustee confirming that (A) the Company has received from or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of
the Indenture, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such opinion of
counsel shall confirm that, the Holders of the outstanding Notes will not
recognize income, gain or loss for federal income tax purposes as a result of
such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case
if such Legal Defeasance had not occurred; (iii) in the case of Covenant
Defeasance, the Company shall have delivered to the Trustee an opinion of
counsel reasonably acceptable to the Trustee to the effect that the Holders of
the outstanding Notes will not recognize income, gain or loss for federal
income tax purposes as a result of such Covenant Defeasance and will be subject
to federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Covenant Defeasance had not occurred,
(iv) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit or insofar as Events of Default from bankruptcy or
insolvency events are concerned, at any time in the period ending on the 91st
day (or a subsequent date if a longer comparable period is then applicable)
after the date of deposit; (v) such Legal Defeasance or Covenant Defeasance
shall not result in a breach or violation of, or constitute a default under any
other material agreement or instrument to which the company is a party or by
which the Company is bound; (vi) the Company shall have delivered to the
Trustee an officers' certificate stating that the deposit was not made by the
Company with the intent of preferring the Holders of Notes over other creditors
of the Company or with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or others; and (vii) the Company shall have
delivered to the Trustee an officers' certificate and an opinion of counsel
each stating that all conditions precedent provided for relating to the Legal
Defeasance or the Covenant Defeasance have been complied with.

GOVERNING LAW

    The Indenture provides that it, the Guarantees and the Notes will be
governed by, and construed in accordance with, the laws of the State of New
York, but without giving effect to principles of conflicts of law to the extent
that the application of the law of another jurisdiction would be required
thereby.

THE TRUSTEE

    State Street Bank and Trust Company is the Trustee under the Indenture. Its
address is 225 Asylum Street, 23rd Floor, Hartford, Connecticut 06103. The
Company has also appointed the Trustee as the initial Registrar, Transfer Agent
and Paying Agent under the Indenture.





                                      -73-
<PAGE>   78
    The Trustee is permitted to become an owner or pledgee of Notes and may
otherwise deal with the Company or its Subsidiaries or any of their Affiliates
with the same rights it would have if it were not Trustee. If, however, the
Trustee acquires any conflicting interest (as defined in the Trust Indenture
Act), it must eliminate such conflict or resign.

    The Indenture provides that in case an Event of Default shall occur (and be
continuing), the Trustee will be required to use the degree of care and skill
of a prudent person in the conduct of such person's own affairs. The Trustee
will be under no obligation to exercise any of its powers under the Indenture
at the request of any of the Holders of the Notes, unless such Holders have
offered the Trustee indemnity reasonably satisfactory to it.

ADDITIONAL INFORMATION

    Anyone who receives this Prospectus may obtain a copy of the Indenture
without charge by writing to Michael Petroleum Corporation, 13101 Northwest
Freeway, Suite 320, Houston, Texas 77040, Attention: Robert L. Swanson.

NO PERSONAL LIABILITY OF DIRECTORS, ADVISORS, MANAGERS, OFFICERS, EMPLOYEES,
INCORPORATORS, MEMBERS AND SHAREHOLDERS

    No director, advisor, manager, officer, employee, incorporator, member or
shareholder of the Company or any Guarantor, as such, shall have any liability
for any obligations of the Company or any Guarantor under the Notes, the
Guarantees, the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation.  Each Holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws, and it is the
view of the SEC that such a waiver is against public policy.

BOOK-ENTRY, DELIVERY AND FORM

    The Old Notes were offered and sold (a) to Qualified Institutional Buyers
in reliance on the exemption from the registration requirements of the
Securities Act provided by Rule 144A ("Rule 144A Notes") and (b) outside the
United States in reliance on Regulation S under the Securities Act ("Regulation
S Notes"). Except as set forth below, Notes will be issued in registered,
global form without interest coupons in minimum denominations of $1,000 and
integral multiples of $1,000 in excess thereof.

    Rule 144A Notes are represented by one Note in registered, global form
without interest coupons (the "Rule 144A Global Note"). The Rule 144A Global
Note was deposited upon issuance with the Trustee as custodian for DTC, in New
York, New York, and registered in the name of DTC or its nominee, in each case
for credit to an account of a direct or indirect participant in DTC as
described below.

    Regulation S Notes initially are represented by one temporary Note in
registered, global form without interest coupons (the "Regulation S Temporary
Global Note"). The Regulation S Temporary Global Note was deposited on behalf
of the subscribers thereof with a custodian for DTC. The Regulation S Temporary
Global Note was registered in the name of a nominee of DTC for credit to the
subscribers' respective accounts at the Euroclear and Cedel Bank. Beneficial
interests in the Regulation S Temporary Global Note may be held only through
Euroclear or Cedel Bank.

    After the occurrence of (i) the expiration of a 40-day restricted period,
as defined under Regulation S (the "Restricted Period"), or (ii) the exchange
of a beneficial interest in the Regulation S Global Notes for a beneficial
interest in a global note representing New Notes upon consummation of the
Exchange Offer and upon delivery of certification that the beneficial owners
thereof are not U.S. persons (as defined in Rule 902(o) under the Securities
Act) or that such beneficial owners purchased such Notes in a transaction that
did not require registration under the Securities Act and are in the process of
obtaining a beneficial interest in the Rule 144A Global Note in exchange for
their beneficial interest in the Regulation S Temporary Global Note, a
beneficial interest in the Regulation S Temporary Global Note may be exchanged
for an interest in one or more permanent Notes in registered, global form
without interest coupons (collectively, the "Regulation S Permanent Global
Notes" and, together with the Regulation S Temporary Global Notes, the
"Regulation S Global Note") (the Regulation S Global Note and the 144A Global
Note collectively, the "Global Notes") which is expected to be deposited with
the Trustee as custodian for, and registered in the name of, a nominee of DTC.
Investors may hold beneficial interests in the Regulation S Permanent Global
Note through organizations other than Euroclear and Cedel Bank that are
Participants in DTC's system. Euroclear and Cedel Bank will hold interests in
the Regulation S Global Note on behalf of their Participants through customers'
securities accounts in their respective names on the books of their respective
depositaries, which are Morgan Guaranty Trust Company of New York, Brussels
office, as operator of Euroclear, and Citibank, N.A., as operator of Cedel
Bank. In turn, each of Euroclear and Cedel Bank will hold such interests in the
Regulation S Global Note in customers' securities accounts in its name on the
books of DTC.





                                      -74-
<PAGE>   79
    The Notes that are issued as described below under the caption "--
Certificated Notes" will be issued in the form of registered definitive
certificates (the "Certificated Notes"). Such Certificated Securities may,
unless the Global Notes have previously been exchanged for Certificated Notes,
be exchanged for an interest in a Global Note representing the principal amount
of Notes being transferred.

    DTC is a limited-purpose trust company that was created to hold securities
for its participating organizations (collectively, the "Participants" or "DTC's
Participants") and to facilitate the clearance and settlement of transactions
in such securities between Participants through electronic book-entry changes
in accounts of its Participants. DTC's Participants include securities brokers
and dealers (including the Initial Purchaser), banks and trust companies,
clearing corporations and certain other organizations. Access to DTC's system
is also available to other entities such as banks, brokers, dealers and trust
companies (collectively, the "Indirect Participants" or "DTC's Indirect
Participants") that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly. Persons who are not Participants
may beneficially own securities held by or on behalf of DTC only through DTC's
Participants or DTC's Indirect Participants.

    The Company expects that, pursuant to procedures established by DTC, (i)
upon deposit of the Global Notes, DTC will credit the accounts of Participants
designated by the Initial Purchaser with portions of the principal amount of
the Global Notes and (ii) ownership of the Notes evidenced by the Global Notes
will be shown on, and the transfer of ownership thereof will be effected only
through, records maintained by DTC (with respect to the interests of DTC's
Participants), DTC's Participants and DTC's Indirect Participants. Prospective
purchasers are advised that the laws of some states require that certain
persons take physical delivery in definitive form of securities that they own.
Consequently, the ability to transfer Notes evidenced by the Global Notes will
be limited to such extent.

    Beneficial interests in one Global Note may be transferred to a person who
takes delivery in the form of a beneficial interest in another Global Note only
upon receipt by the Trustee of a written certification (in the form provided in
the Indenture) to the effect that such transfer is being made in accordance
with the Indenture and with the Securities Act and any applicable securities
laws of any state of the United States or any other jurisdiction.  Any
beneficial interest in one of the Global Notes that is transferred to a person
who takes delivery in the form of a beneficial interest in another Global Note
will, upon transfer, cease to be a beneficial interest in such Global Note and
become a beneficial interest in the other Global Note and accordingly, will
thereafter be subject to all transfer restrictions, if any, and other
procedures applicable to beneficial interests in such other Global Note for as
long as it remains such a beneficial interest.

    So long as the Global Note holder is the registered owner of any Notes, the
Global Note holder will be considered the sole holder under the Indenture of
any Notes evidenced by the Global Notes. Beneficial owners of Notes evidenced
by the Global Notes will not be considered the owners or holders thereof under
the Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any
aspect of the records of DTC or for maintaining, supervising or reviewing any
records of DTC relating to the Notes.

    Payments in respect of the principal of and premium, interest and
Liquidated Damages, if any, on any Notes registered in the name of the Global
Note holder on the applicable record date will be payable by the Trustee to or
at the direction of the Global Note holder in its capacity as the registered
holder under the Indenture. Under the terms of the Indenture, the Company and
the Trustee may treat the persons in whose names Notes, including the Global
Notes, are registered as the owners thereof for the purpose of receiving such
payments. Consequently, neither the Company nor the Trustee has or will have
any responsibility or liability for the payment of such amounts to beneficial
owners of Notes. The Company believes, however, that it is currently the policy
of DTC to immediately credit the accounts of the relevant Participants with
such payments, in amounts proportionate to their respective holdings of
beneficial interests in the relevant security as shown on the records of DTC.
Payments by DTC's Participants and DTC's Indirect Participants to the
beneficial owners of Notes will be governed by standing instructions and
customary practice and will be the responsibility of DTC's Participants or
DTC's Indirect Participants.

ADDITIONAL INFORMATION CONCERNING EUROCLEAR AND CEDEL BANK

    Euroclear and Cedel Bank hold securities for participating organizations
and facilitate the clearance and settlement of securities transactions between
their respective participants through electronic book-entry changes in accounts
of such participants. Euroclear and Cedel Bank provide to their participants,
among other things, services for safekeeping, administration, clearance and
settlement of internationally traded securities and securities lending and
borrowing.  Euroclear and Cedel Bank interface with domestic securities
markets. Euroclear and Cedel Bank participants are financial institutions such
as underwriters, securities brokers and dealers, banks, trust companies and





                                      -75-
<PAGE>   80
certain other organizations. Indirect access to Euroclear and Cedel Bank is
also available to others such as banks, brokers, dealers and trust companies
that clear through or maintain a custodian relationship with a Euroclear or
Cedel Bank participant, either directly or indirectly.

    When beneficial interests are to be transferred from the account of a
Participant (other than Morgan Guaranty Trust Company of New York and Citibank,
N.A., as depositaries for Euroclear and Cedel Bank, respectively) to the
account of a Euroclear participant or a Cedel Bank participant, the purchaser
must send instructions to Euroclear or Cedel Bank through a participant at
least one business day prior to settlement. Euroclear or Cedel Bank, as the
case may be, will instruct Morgan Guaranty Trust Company of New York or
Citibank, N.A. to receive the beneficial interests against payment. Payment
will include interest and, if any, Liquidated Damages attributable to the
beneficial interest from and including the last payment date to and excluding
the settlement date, on the basis of a calendar year consisting of twelve
30-day calendar months. For transactions settling on the 31st day of the month,
payment will include interest and, if any, Liquidated Damages accrued to and
excluding the first day of the following month. Payment will then be made by
Morgan Guaranty Trust Company of New York or Citibank, N.A., as the case may
be, to the Participant's account against delivery of the beneficial interests.
After settlement has been completed, the beneficial interests will be credited
to the respective clearing systems and by the clearing system, in accordance
with its usual procedures, to the Euroclear participants' or Cedel Bank
participants' account. Credit for the beneficial interests will appear on the
next business day (European time) and the cash debit will be back-valued to,
and interest attributable to the beneficial interests will accrue from, the
value date (which would be the preceding business day when settlement occurs in
New York). If settlement is not completed on the intended value date (i.e., the
trade fails), the Euroclear or Cedel Bank cash debit will instead be valued as
of the actual settlement date.

    Euroclear participants and Cedel Bank participants will need to make
available to the respective clearing systems the funds necessary to process
same-day funds settlement. The most direct means of doing so is to pre-position
funds for settlement, either from cash on hand or existing lines of credit, as
they would for any settlement occurring within Euroclear or Cedel Bank. Under
this approach, such participants may take on credit exposure to Euroclear or
Cedel Bank until the beneficial interests are credited to their accounts one
day later. Finally, day traders that use Euroclear or Cedel Bank and that
purchase beneficial interests from Participants for credit to Euroclear
participants or Cedel Bank participants should note that their trades would
automatically fall on the sale side unless affirmative action were taken to
avoid these potential problems.

    Due to time zone differences in their favor, Euroclear participants and
Cedel Bank participants may employ their customary procedures for transactions
in which beneficial interests are to be transferred by the respective clearing
system, through Morgan Guaranty Trust Company of New York or Citibank, N.A., to
another Participant. The seller must send instructions to Euroclear or Cedel
Bank through a participant at least one business day prior to settlement. In
these cases, Euroclear or Cedel Bank will instruct Morgan Guaranty Trust
Company of New York or Citibank, N.A., as the case may be, to credit the
beneficial interests to the Participant's account against payment. Payment will
include interest and, if any, Liquidated Damages attributable to the beneficial
interest from and including the last payment date to and excluding the
settlement date, on the basis of a calendar year consisting of twelve 30-day
calendar months.  For transactions settling on the 31st day of the month,
payment will include interest and Liquidated Damages, if any, accrued to and
excluding the first day of the following month. The payment will then be
reflected in the account of the Euroclear participant or Cedel Bank participant
the following business day, and receipt of the cash proceeds in the Euroclear
or Cedel Bank participant's account will be back-valued to the value date
(which would be the preceding business day, when settlement occurs in New
York). If the Euroclear participant or Cedel Bank participant has a line of
credit with its representative clearing system and elects to draw on such line
of credit in anticipation of receipt of the sale proceeds in its account, the
back-valuation may substantially reduce or offset any overdraft charges
incurred over that one-day period. If settlement is not completed on the
intended value date (i.e., if trade fails), receipt of the cash proceeds in the
Euroclear or Cedel Bank participant's account would instead be valued as of the
actual settlement date.

CERTIFICATED SECURITIES

    Subject to certain conditions, any person having a beneficial interest in a
Global Note may, upon request to the Trustee, exchange such beneficial interest
for Notes in the form of Certificated Securities. Upon any such issuance, the
Trustee is required to register such Certificated Securities in the name of,
and cause the same to be delivered to, such person or persons (or the nominee
of any thereof). [All such certificated Notes would be subject to the legend
requirements described herein under the caption "Notice to Investors."] In
addition, if (i) the Company notifies the Trustee in writing that DTC is no
longer willing or able to act as a depositary and the Company is unable to
locate a qualified successor within 90 days or (ii) the Company, at its option,
notifies the Trustee in writing that it elects to cause the issuance of Notes
in the form of Certificated Securities under the Indenture, then, upon
surrender by the Global Note Holder of the Global Notes, Notes in such form
will be issued to each person that the Global Note Holder and DTC identify as
being the beneficial owner of the related Notes.





                                      -76-
<PAGE>   81

    Neither the Company nor the Trustee, nor any agent for either of them, will
be liable for any delay by the Global Note Holder or DTC in identifying the
beneficial owners of Notes, and the Company and the Trustee, and each agent of
any of them, may conclusively rely on, and will be protected in relying on,
instructions from the Global Note Holder or DTC for all purposes.

   
               UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
    

   
    The following is a summary  of the material U.S. federal income tax
considerations relating to the exchange of the Old Notes for New Notes and the
ownership and disposition of the New Notes. This discussion is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations,
Internal Revenue Service ("IRS") rulings and administrative pronouncements and
judicial decisions now in effect, all of which are subject to change (possibly
with retroactive effect) or different interpretations. This discussion does not
purport to deal with all aspects of federal income taxation that may be
relevant to a particular investor's decision to exchange the Old Notes for the
New Notes, and it is not intended to be wholly applicable to all categories of
investors, some of which, such as dealers in securities, banks, insurance
companies and tax-exempt organizations, may be subject to special rules. In
addition, this discussion is limited to persons that will hold the New Notes as
a "capital asset" within the meaning of section 1221 of the Code.  EACH HOLDER
OF OLD NOTES IS URGED TO CONSULT ITS OWN TAX ADVISOR AS TO THE PARTICULAR TAX
CONSEQUENCES OF EXCHANGING OLD NOTES FOR NEW NOTES, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY STATE, LOCAL OR FOREIGN LAWS.
    
        
EXCHANGE OFFER

   
    The exchange of the New Notes for the Old Notes pursuant to the Exchange
Offer should not constitute a material modification of the terms of the Notes
and, therefore, such exchange should not constitute an exchange for U.S.
federal income tax purposes.  Accordingly, such exchange should have no U.S.
federal income tax consequences to U.S. holders of the New Notes, and the
holding period of the New Notes will include the holding period of the Old
Notes.  The adjusted tax basis of the New Notes will be the same as that of the
Old Notes immediately before the exchange.
    
        
STATED INTEREST AND ORIGINAL ISSUE DISCOUNT

   
    The stated interest on the New Notes will be includable in the income of a
holder as ordinary income for United States federal income tax purposes at the
time it is received or accrued in accordance with the holder's method of tax
accounting. Failure of the Company to consummate the Exchange Offer or to file
or cause to be declared effective the Shelf Registration Statement will cause
Liquidated Damages calculated as additional interest to accrue on the Old Notes
in the manner described therein. According to U.S. Treasury regulations, the
possibility of a change in the interest rate will not affect the amount of
interest income recognized by a holder (or the timing of such recognition) if
the likelihood of the change, as of the date the Old Notes were issued, was
remote. The Company believes that the likelihood of a change in the interest
rate on the Old Notes was remote and does not intend to treat the possibility
of a change in the interest rate as affecting the yield to maturity of any
Note.
    
        
   
    The Old Notes will be considered to have been issued with original issue 
discount ("OID") because the stated redemption price at maturity of the Old
Notes (which, for these purposes, will be its stated principal amount) 
exceeded the issue price of the Old Notes. The amount of OID on each Old Note
was initially $17.51 per $1,000 in principal amount of Old Notes.
    
        
   
    A holder (regardless of its method of accounting) will be required to i
include in income the sum of the daily portions of OID with respect to each New
Note for each day during the taxable year or portion of a taxable year in which
such holder holds the Note (such sum, "Accrued OID"), with the result that a
holder will be required to include amounts in income without any current
corresponding receipt of cash. The daily portion is determined by allocating to
each day of any accrual period within a taxable year a pro rata portion of an
amount equal to the adjusted issue price of the New Note at the beginning of
the accrual period multiplied by the yield to maturity of the New Note. The
adjusted issue price of a New Note at the beginning of any accrual period is
the issue price of the New Note increased by the Accrued OID for all prior 
accrual periods (less all payments made on the New Notes other than payments of
stated interest on the New Notes). The Company will annually furnish to record
holders of the New Notes and to the IRS information with respect to any OID
accruing during the calendar year as may be required by applicable regulations.

MARKET DISCOUNT

   
    Holders of the New Notes should note that the resale of the New Notes may be
adversely affected by the market discount provisions of sections 1276 through
1278 of the Code. Under the market discount rules, if a holder of an Old Note
(other than a holder who purchased the New Note upon original issuance)
purchases it at a market discount (i.e., at a price below its stated redemption
price at maturity) in excess of a statutorily-defined de minimis amount and
thereafter recognizes gain upon a disposition or retirement of the New Note,
then the lesser of the gain recognized or the portion of the market discount
that accrued on a ratable basis (or, if elected, on a constant interest rate
basis) generally will be treated as ordinary income at the time of the
disposition. Moreover, any market discount in a New Note may be taxable to an
investor to the extent of appreciation at the time of certain otherwise
non-taxable transactions (e.g., gifts). Absent an election to include market
discount in income as it accrues, a holder of a market discount debt instrument
may be required to defer a portion of any interest expense that otherwise may
be deductible on any indebtedness incurred or maintained to purchase or carry
such debt instrument until the holder disposes of the debt instrument in a
taxable transaction.
    
        
SALE, EXCHANGE OR RETIREMENT OF THE NEW NOTES

   
     Each holder of New Notes generally will recognize gain or loss upon the
sale, exchange, repurchase, redemption, retirement or other disposition of those
New Notes measured by the difference (if any) between (i) the amount of cash and
the fair market value of any property received (except to the extent that such
cash or other property is attributable to the payment of accrued interest not
previously included in income, which amount will be taxable as ordinary income)
and (ii) the holder's adjusted tax basis in those New Notes (including any
market discount previously included in income by the holder). Any such gain or
loss recognized on the sale, exchange, repurchase, redemption, retirement or
other disposition of a New Note should be capital gain or loss (except as
discussed under "Market Discount" above), and would be long-term capital gain or
loss if the New Note had been held for more than one year at the time of the
sale or exchange. If the New Notes had been held by a noncorporate holder for
more than 12 months but not more than 18 months, such capital gains generally
shall be subject to tax at a maximum 28% rate. If the New Notes had been held by
a non-corporate holder for more than 18 months, however, such capital gain
generally will be subject to tax at a maximum 20% rate. An investor's initial
tax basis in a New Note will be the cash price it paid therefor.

<PAGE>   83
BACKUP WITHHOLDING

   
    A holder of New Notes may be subject to "backup withholding" at a rate of 
31% with respect to certain "reportable payments," including interest payments
and, under certain circumstances, principal payments on the New Notes. These
backup withholding rules apply if the holder, among other things, (i) fails to
furnish a social security number or other taxpayer identification number
("TIN") certified under penalties of perjury within a reasonable time after the
request therefor, (ii) furnishes an incorrect TIN, (iii) fails to report
properly interest, or (iv) under certain circumstances, fails to provide a
certified statement, signed under penalties of perjury, that the TIN furnished
is the correct number and that such holder is not subject to backup
withholding. A holder who does not provide the Company with its correct TIN
also may be subject to penalties imposed by the IRS. Any amount withheld from a
payment to a holder under the backup withholding rules is creditable against
the holder's federal income tax liability, provided that the required
information is furnished to the IRS. Backup withholding will not apply,
however, with respect to payments made to certain holders, including
corporations, tax-exempt organizations and certain foreign persons ("exempt
recipients"), provided their exemptions from backup withholding are properly
established.
    
        
   
    The amount of any "reportable payments" including interest made to the
holders of New Notes (other than to holders which are exempt recipients) and the
amount of tax withheld, if any, with respect to such payments will be reported
to such holders and to the IRS for each calendar year.
    

FOREIGN HOLDERS

   
    The following discussion is a summary of the principal U.S. federal income
and estate tax consequences to a Foreign Person that holds a New Note. The term
"Foreign Person" means a nonresident alien individual or foreign corporation,
but only if the income or gain on the New Note is not "effectively connected 
with the conduct of a trade or business within the U.S." If the income or gain
on the New Note is "effectively connected with the conduct of a trade or
business within the U.S.," then the nonresident alien individual or foreign
corporation will be subject to tax on such income or gain in essentially the
same manner as a U.S. citizen or resident or a domestic corporation, as
discussed above, and in the case of a foreign corporation, may also be subject
to a 30% (or lower applicable treaty rate) branch profits tax.
    
        
   
    Under the portfolio interest exception to the general rules for the
withholding of a tax on interest paid to a Foreign Person, a Foreign Person will
not be subject to U.S. federal income tax (or to withholding) on interest
payments on a New Note, provided that (i) the Foreign Person does not actually
or constructively own 10% or more of the total combined voting power of all
classes of stock of the Company entitled to vote and is not a controlled foreign
corporation with respect to the U.S. that is related to the Company through
stock ownership and (ii) the Company, its paying agent or the person who would
otherwise be required to withhold tax receives either (A) a statement (an
"Owner's Statement") signed under penalties of perjury by the beneficial owner
of the New Note in which the owner certifies that the owner is not a U.S.
person, or in the case of an individual, that he is neither a citizen nor a
resident of the United States, and which provides the owner's name and address,
or (B) a statement signed under penalties of perjury by the Financial
Institution holding the New Note on behalf of the beneficial owner, together
with a copy of the Owner's Statement.  The term "Financial Institution" means a
securities clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of its trade or business and that
holds a New Note on behalf of the owner of the New Note. A Foreign Person who
does not qualify for the "portfolio interest" exception, would, under current
law, generally be subject to the U.S. federal withholding tax at a flat rate of
30% (or lower applicable treaty rate) on interest payments.
    
        
   
    In general, gain recognized by a Foreign Person upon the redemption,
retirement, sale or exchange of a Note (including any gain representing accrued
market discount) will not be subject to U.S. federal income tax. However, a
Foreign Person may be subject to U.S. federal income tax at a flat rate of 30%
(unless exempt by an applicable treaty) on any such gain if the Foreign Person
is an individual present in the U.S. for 183 days or more during the taxable
year in which the New Note is redeemed, retired, sold or exchanged, and certain
other requirements are met.
    

   
    Subject to applicable estate tax treaty provisions, New Notes held at the 
time of death (or New Notes transferred before death but subject to certain
retained rights or powers) by an individual who at the time of death is a
nonresident alien for estate tax purposes will not be included in such
individual's gross estate for U.S. federal estate tax purposes provided that
the individual does not actually or constructively own 10% or more of the total
combined voting power of all classes of stock of the Company entitled to vote
or hold the New Notes in connection with a U.S. trade or business.

                          DESCRIPTION OF CAPITAL STOCK

CAPITAL STOCK

    The authorized capital stock of the Company consists of (i) 100,000,000
shares of common stock, par value $0.10 per share, and (ii) 50,000,000 shares
of preferred stock, par value $0.10 per share. There currently are 10,000
shares of the Company's common stock outstanding, all of which are owned of
record and beneficially by MHI. No shares of the Company's preferred stock are
outstanding.

    The authorized capital stock of MHI consists of (i) 100,000,000 shares of
Common Stock, par value $.01 per share, and (ii) 50,000,000 shares of preferred
stock, par value $.01 per share ("Preferred Stock"). On March 31, 1998, there
were seven holders of record of Common Stock with 773,425 shares outstanding,
and no shares of Preferred Stock were outstanding.

COMMON STOCK

    Holders of shares of Common Stock are entitled to share ratably in such
dividends as may be declared by the Board of Directors and paid by MHI out of
funds legally available therefor, subject to prior rights of any outstanding
shares of any preferred stock. In the event of any dissolution, liquidation or
winding up of MHI, holders of shares of Common Stock are entitled to share
ratably in assets remaining after payment of all liabilities and liquidation
preferences, if any.

    Except as otherwise required by law or the Articles of Incorporation, the
holders of Common Stock are entitled to one vote per share on all matters voted
on by shareholders, including the election of directors.

    Holders of shares of Common Stock have no preemptive, cumulative voting,
subscription, redemption or conversion rights. The rights, preferences and
privileges of holders of Common Stock are subject to the rights, preferences
and privileges granted to the holders of any series of preferred stock which
the Company may issue in the future.

    The rights and privileges of the holders of the Company's common stock are
substantially similar to those of the holders of the Common Stock.

PREFERRED STOCK

    The Board of Directors may, without further action by the shareholders of
MHI, from time to time, direct the issuance of fully authorized shares of
preferred stock in classes or series and may, at the time of issuance,
determine the powers, rights, preferences and limitations of each class or
series. Satisfaction of any dividend preferences on outstanding shares of
preferred stock may reduce the amount of funds available for the payment of
dividends on Common Stock. Also, holders of preferred stock may be entitled to
receive a preference payment in the event of any liquidation, dissolution or
winding up of MHI before any payment is made to the holders of Common Stock.
Under certain circumstances, the issuance of such preferred stock may render
more difficult or tend to discourage a merger, tender offer or proxy contest,
the assumption of control by a holder of a large block of MHI's securities or
the removal of incumbent management.

    The rights and privileges of the holders of the Company's preferred stock
are substantially similar to those of the holders of the Preferred Stock.

SPECIAL PROVISIONS OF THE ARTICLES OF INCORPORATION AND BYLAWS

    The Articles of Incorporation and Bylaws of MHI include certain provisions
that could have anti-takeover effects.  The provisions enhance the likelihood
of continuity and stability in the composition of, and in the policies
formulated by, the Board of Directors.

    Following is a summary of certain of the provisions contained in the
Articles of Incorporation and Bylaws of MHI.

Number of Directors; Filling Vacancies; Removal

    The Bylaws provide that the Board of Directors will fix the number of
members of the Board of Directors, provided that no decrease will have the
effect of shortening the term of any incumbent Director, and that the number of
directors shall never be less than one. The Bylaws of MHI provide that the
Board of Directors, acting by majority





                                      -80-
<PAGE>   85
vote of the directors then in office, may fill any newly created directorship
or vacancies on the Board of Directors; however, the Board of Directors may not
fill more than two such vacancies arising from an increase in the number of
directors during the period between any two successive annual meetings of
shareholders.

    The Bylaws of MHI provide that any Director or the entire board of
directors may be removed with or without cause at any meeting of shareholders
called expressly for that purpose at which a quorum of shareholders is present,
by a vote of the holders of a majority of the shares then entitled to vote at
an election of directors.

Special Meetings

    The Bylaws provide that special meetings of stockholders may be called by
the President of MHI, the Board of Directors or the Chairman of the Board of
Directors, or by written request signed by the holder or holders of at least
10% of all of the then issued and outstanding shares of the capital stock of
MHI entitled to vote at such meeting and stating the purpose or purposes of the
meeting.

Limitations Imposed by Texas Law

    The Texas Business Corporation Act (the "TBCA") authorizes corporations to
limit or eliminate the personal liability of directors to corporations and
their shareholders for monetary damages for breach of their fiduciary duty as
directors except for liability of a director resulting from (i) a breach of
such director's duty of loyalty to the corporation or its shareholders, (ii) an
act or omission that is not in good faith or that involves intentional
misconduct or a knowing violation of laws, (iii) a transaction from which the
director received an improper personal benefit or (iv) an act or omission for
which the liability of the director is expressly provided by an applicable
statute. The Articles of Incorporation of MHI limit the liability of directors
(in their capacity as directors but not in their capacity as officers) to MHI
or its shareholders to the fullest extent permitted by the TBCA. The inclusion
of this provision in the Articles of Incorporation may reduce the likelihood of
derivative litigation against directors and may discourage or deter
shareholders from suing directors for breach of their duty of care, even though
such an action, if successful, might otherwise benefit MHI and its
shareholders. The inclusion of such provisions in the Articles of Incorporation
together with a provision requiring MHI to indemnify its directors, officers
and certain other individuals against certain liabilities, is intended to
enable MHI to attract qualified persons to serve as directors who might
otherwise be reluctant to do so. The SEC has taken the position that personal
liability of directors for violations of the federal securities laws cannot be
limited and that indemnification by the issuer for such violations is
unenforceable.

    The Articles of Incorporation and Bylaws of the Company are substantially
the same as those of MHI.

WARRANTS

    Upon the closing of the sale of the Old Notes, the repayment of the
indebtedness under the T.E.P. Financing and the purchase of the Net Profits
Interest on April 2, 1998, MHI and the Company canceled their existing warrants
previously granted to Cambrian in exchange for a Warrant to purchase 38,671
shares of Common Stock for an exercise price of $8.00 per share. The Warrant
expires August 12, 2001 and contains provisions for registration rights for the
shares of Common Stock acquired upon exercise (see "--Registration Rights"
below), as well as customary anti-dilution provisions, including provisions
providing for adjustments in the exercise price and number of shares in the
event MHI issues additional shares of Common Stock for cash or non-cash
consideration less than the exercise price then in effect. The terms of the
Warrant further provide that at any time after the Common Stock is traded on a
national securities exchange, the Warrant may be exercised by being exchanged
in whole or in part for a number of shares of Common Stock equal to the
difference between the fair market value of the designated number of shares of
Common Stock and the aggregate exercise price then in effect for those
designated shares. "Fair market value" for this purpose includes the last sale
price of the Common Stock reported on a national securities exchange or the
Nasdaq National Market.

    In addition, during 1997 MHI granted a Warrant to an individual seller of
oil and natural gas properties which entitles the holder to purchase up to
2,900 shares of Common Stock for a purchase price equal to that price per share
which is 125% of the initial public offering price of the Common Stock. Unless
earlier terminated, the warrant expires on that date which is five years from
the date of the initial public offering.

REGISTRATION RIGHTS

    In connection with the issuance to Cambrian of the Warrant to purchase up
to 38,671 shares of Common Stock, MHI granted registration rights regarding
such shares. If at any time prior to the expiration of the Warrant in August
2001, MHI registers any securities for sale pursuant to a registration
statement (with the exception of a Form S-8,





                                      -81-
<PAGE>   86
S-4 or other similar form), upon request by any of the holders of the
outstanding shares underlying the Warrant, MHI shall be required, subject to
certain conditions, to include such securities as a part of such registration
statement.  In addition, subject to certain conditions, the holders of not less
than 51% of the shares of Common Stock underlying the Warrant may request, on
one occasion at any time prior to August 2001, that MHI register such
securities for public sale pursuant to a registration statement under the
Securities Act. Individual holders of such shares shall also have certain
demand registration rights, but principally at such holder's cost.

    The registration rights provisions in the Cambrian Warrant contain
provisions obligating MHI to indemnify Cambrian for certain liabilities
incurred by it or its successors, including liabilities under the federal
securities laws.

SHAREHOLDERS AGREEMENT

    The current shareholders of MHI are parties to a shareholders agreement
dated as of December 4, 1996 (the "Shareholders Agreement"). Under the terms of
the Shareholders Agreement, if a shareholder wishes to sell shares pursuant to
a bona fide offer to purchase them, then the shareholders (other than the
selling shareholder) have the right to purchase those shares on the same terms
in accordance with the proportion of shares of those shareholders electing to
so purchase. If no shareholder exercises that right, then MHI has the right to
purchase those shares on the same terms as set forth in the bona fide offer. If
both MHI and the shareholders do not elect to purchase all of the shares that
are subject to the bona fide offer, then the selling shareholder may sell those
shares not purchased by MHI and the other shareholders pursuant to the terms of
the bona fide offer. If a shareholder is forced to make an involuntary transfer
of Common Stock (by divorce, judicial order or termination of employment), then
the shareholders (other than the transferring shareholder) have the right to
purchase those shares at a price determined in accordance with the Shareholders
Agreement in accordance with the proportion of shares of those shareholders
electing to so purchase. If no shareholder exercises that right, then MHI has
the right to purchase those shares in accordance with the Shareholders
Agreement. If both MHI and the shareholders do not elect to purchase all of the
shares that are subject to involuntary transfer, then the transfer may take
place. Upon the death of a shareholder, MHI is obligated to purchase the shares
owned by the deceased shareholder. The Shareholders Agreement also provides
that each of Messrs. Hart, Farmar, Holditch and Smith shall have the right to
designate one nominee for membership on MHI's Board of Directors and that the
shareholders of MHI will vote their shares of Common Stock for the election of
such nominees. The Shareholders Agreement terminates upon the bankruptcy of MHI
or any merger or consolidation of MHI in which MHI is not the surviving
corporation.  Cambrian is not obligated to become a party to the Shareholders
Agreement if Cambrian exercises its Warrant.

                              PLAN OF DISTRIBUTION

    Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to the Company, the Company believes
that, with the exceptions set forth below, New Notes issued pursuant to the
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by any person receiving such New Notes, whether or not
such person is the holder (other than any such holder or such other person
which is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act; provided that, the New Notes are
acquired in the ordinary course of business of the holder or such other person
and neither the holder nor such other person is engaging or intends to engage
in a distribution of the New Notes or has an arrangement or understanding with
any person to participate in the distribution of such New Notes. The Company,
however, has not sought, and does not intend to seek, its own no-action letter
and there can be no assurance that the Commission's staff would make a similar
determination with respect to the Exchange Offer. Any holder who tenders in the
Exchange Offer for the purpose of participating in a distribution of the New
Notes cannot rely on this interpretation by the Commission's staff and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction.

    Each broker-dealer that holds Old Notes that were acquired by that
broker-dealer as a result of market-making activities or other trading
activities may exchange such Old Notes (other than for Old Notes that were
acquired directly from the Company or any affiliate of the Company) pursuant to
the Exchange Offer; provided however, such broker-dealer may be deemed to be an
"underwriter" within the meaning of the Securities Act and must, therefore,
deliver a prospectus meeting the requirements of the Securities Act in
connection with its initial resale of each New Note received in the Exchange
Offer.  This Prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of New Notes in
such circumstances. The Company has agreed that it will make this Prospectus,
as amended or supplemented, available to any broker-dealer for use in
connection with any such resale for a period of one year following the
Expiration Date, or such shorter period ending on the date that all New Notes
received in the Exchange Offer have been resold by any such broker-dealer.

    The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through brokers or dealers who may
receive compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such New Notes. Because any
broker-dealer that resells New Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such New Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act, any profit on any such
resale of New Notes and any commissions or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act.
The Letter of Transmittal states that, by acknowledging that it will deliver,
and by delivering, a Prospectus, a broker-dealer will not be deemed to admit
that it is an "underwriter" within the meaning of the Securities Act.

    The Company will promptly send additional copies of this Prospectus and any
amendment or supplement to this Prospectus to any broker-dealer that requests
such documents in the Letter of Transmittal for such period of time as such
persons must comply with such requirements in order to resell the New Notes.
The Company has agreed to pay all expenses relating to their performance under
the Registration Rights Agreement, including the costs of providing this
Prospectus, and to indemnify the holders of the Old Notes against certain
liabilities, including liabilities under the Securities Act.

                       TRANSFER RESTRICTIONS ON OLD NOTES

OFFERS AND SALES BY THE INITIAL PURCHASERS

    The Old Notes have not been registered under the Securities Act and may not
be offered or sold in the United States, or to, or for the account or benefit
of, U.S. Persons except in accordance with an applicable exemption from the
registration requirements thereof. Accordingly the Old Notes were offered and
sold only (i) to QIBs under Rule 144A under the Securities Act and (ii) outside
the United States to persons other than U.S. Persons ("foreign purchasers,"
which term shall include dealers or other professional fiduciaries in the
United States acting on a discretionary basis for foreign beneficial owners
(other than an estate or trust) in offshore transactions meeting the
requirements of Rule 904 of Regulation S under the Securities Act ("Regulation
S")). As used herein, the terms "offshore transaction," "United States" and
"U.S. Person" have the respective meanings given to them in Regulation S.

INVESTOR REPRESENTATIONS AND RESTRICTIONS ON RESALE

    Each purchaser of the Old Notes was deemed to have represented and agreed
as follows:

    (1) it was acquiring the Old Notes for its own account or for an account
with respect to which it exercises sole investment discretion, and that it or
such account was (a) a QIB or (b) a non-U.S. Person that is outside the United
States;

    (2) it acknowledged that the Old Notes were not registered under the
Securities Act and may not be offered or sold within the United States or to,
or for the account or benefit of, U.S. Persons except as permitted below;

    (3) it understood and agreed (x) that such Old Notes were being offered
only in a transaction not involving any public offering within the meaning of
the Securities Act, and (y) that (A) if within two years after the date of
original issuance of the Old Notes or if within three months after it ceases to
be an affiliate (within the meaning of Rule 144 under the Securities Act) of
the Company, it decides to resell, pledge or otherwise transfer the Old Notes
on which the legend set forth below appears, such Old Notes may be resold,
pledged or transferred only (i) to the Company, (ii) so long as such securities
are eligible for resale pursuant to Rule 144A, to a person whom the seller
reasonably believes is a QIB that purchases for its own account or for the
account of a QIB to whom notice is given that the resale, pledge or transfer is
being made in reliance on Rule 144A (as indicated by the box checked by the
transferor on the Certificate of Transfer on the reverse of the Old Note if
such Old Note is not in book entry form), (iii) pursuant to offers and sales
that occur outside the United States in a transaction meeting the requirements

UNAUDITED PRO FORMA FINANCIAL STATEMENTS



   
The following unaudited pro forma statement of operations for the year ended
December 31, 1997 includes pro forma adjustments that give effect to the
issuance of $135 million of senior note obligations and the application of the
net proceeds therefrom to the repayment of the T.E.P. Financing, the purchase of
the Net Profits Interest and the acquisition of the Enron Properties and the
Conoco Properties as if such transactions had been completed January 1, 1997.
Similarly, the unaudited pro forma statement of operations for the three months
ended March 31, 1998 includes pro forma adjustments that give effect to the
issuance of $135 million of senior note obligations and the application of the
net proceeds therefrom to the repayment of the T.E.P. Financing, the purchase of
the Net Profits Interest and the acquisition of the Enron Properties and the
Conoco Properties as if such transitions had been completed January 1, 1998. The
Lobo Lease does not effect the pro forma statement of operations as it is an
acquisition of undeveloped leases. The unaudited pro forma balance sheet has
been prepared as if such transactions occurred on March 31, 1998. 
    

The unaudited pro forma financial statements are based on the assumptions set
forth in the notes to such unaudited pro forma financial statements. Management
believes that the pro forma adjustments and the underlying assumptions
reasonably present the significant effects of the acquisitions and other
transactions. Such pro forma information should be read in conjunction with the
Company's financial statements and related notes thereto and the statements of
revenues and direct operating expenses and related notes thereto of the Enron
Properties and the Conoco Properties included elsewhere herein and is not
necessarily indicative of the operating results or financial position that
actually would have occurred had the acquisitions and other transactions
occurred as of the dates indicated above, nor do they purport to indicate
operating results or financial position which may be attained in the future.

MICHAEL PETROLEUM CORPORATION
NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS
(Tables in thousands of dollars)

   
     The following unaudited pro forma statement of operations for the year
ended December 31, 1997 includes pro forma adjustments that give effect to the
issuance of $135 million of senior note obligations (issued at a discount of
1.751%) and the application of the net proceeds therefrom to the repayment of
the T.E.P. Financing, the purchase of the Net Profits Interest and the
acquisition of the Enron Properties and the Conoco Properties as if such
transactions had been completed January 1, 1997. Similarly, the unaudited pro
forma statement of operations for the three months ended March 31, 1998 includes
pro forma adjustments that give effect to the issuance of $135 million of senior
note obligations and the application of the net proceeds therefrom to the
repayment of the T.E.P. Financing, the purchase of the Net Profits Interest and
the acquisition of the Enron Properties and the Conoco Properties as if such
transactions had been completed January 1, 1998. The Lobo Lease does not effect
the pro forma statement of operations as it is an acquisition of an undeveloped
lease. The unaudited pro forma balance sheet has been prepared as if such
transactions occurred on March 31, 1998.
    

(a)      To reflect the recognition of revenues and direct operating expenses
         from the acquisitions for the year ended December 31, 1997.

(b)      To reflect additional estimated depreciation, depletion and
         amortization ("DD&A") attributable to the acquisition of the Enron
         Properties, the Conoco Properties and the Net Profits Interest as if
         such acquisitions had occurred on January 1, 1997. The additional DD&A
         amounts were calculated on the units-of-production method based on pro
         forma capitalized costs and estimates of pro forma proved developed and
         undeveloped reserves. The Company's actual and pro forma DD&A for the
         year ended December 31, 1997 were approximately $1.00 and $.84 per Mcfe
         produced, respectively.

(c)      To eliminate the historical interest expense of approximately $2.2
         million related to the T.E.P. Financing and to reflect the interest
         expense which results from the issuance of $135 million of senior note
         obligations with a stated interest rate of 11.50%. Interest expense
         also includes one year of amortization of $4.8 million of deferred loan
         costs and one year amortization of the $2.4 million discount on senior
         notes, which are being amortized on a straight-line basis over the
         seven year term of the notes.

</TABLE>

         A 1/8% change in interest rates would have the impact of increasing
         total pro forma interest expense by approximately $169,000.

(d)      To reflect income taxes on the pro forma adjustments at an estimated
         effective tax rate of 35%.

   
(e)      To reflect the recognition of revenues and direct operating expenses
         from the acquisitions for the three months ended March 31, 1998.

(f)      To reflect additional estimated depreciation, depletion and
         amortization ("DD&A") attributable to the acquisition of the Enron
         Properties, the Conoco Properties and the Net Profits Interest as if
         such acquisitions had occurred on January 1, 1998. The additional DD&A
         amounts were calculated on the units-of-production method based on pro
         forma capitalized costs and estimates of pro forma proved developed and
         undeveloped reserves. The Company's actual and pro forma DD&A for the
         three months ended March 31, 1998 were approximately $.87 and $.61 per
         Mcfe produced, respectively.

(g)      To eliminate the historical interest expense of approximately $900,000
         related to the T.E.P. financing and to reflect the interest expense
         which results from the issuance of $135 million senior note obligations
         with a stated interest rate of 11.50%. Interest expense also includes
         three months of amortization of $4.8 million of deferred loan costs and
         three months amortization of the $2.4 million discount on senior notes,
         which are being amortized on a straight-line basis over the seven year
         term of the notes.

REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholder of
Michael Petroleum Corporation:

We have audited the accompanying balance sheet of Michael Petroleum Corporation
as of December 31, 1996 and 1997, and the related statements of operations,
stockholder's deficit, and cash flows for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Michael Petroleum Corporation
as of December 31, 1996 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1997 in
conformity with generally accepted accounting principles.

As discussed in Note 1 to the financial statements, the Company changed its
method of accounting for impairment of long-lived assets in 1996.

                                                    Coopers & Lybrand L.L.P.
   
Houston, Texas
March 6, 1998 (except for Note 12
for which the date is June 16, 1998)

MICHAEL PETROLEUM CORPORATION
NOTES TO FINANCIAL STATEMENTS
(Information for the three month period ended
March 31, 1997 and 1998 is unaudited)
    


1.       NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

         NATURE OF OPERATIONS AND BASIS OF PRESENTATION

         Michael Petroleum Corporation (the "Company" or "MPC") is engaged in
         the acquisition, exploration and development of oil and natural gas
         properties principally located in the Lobo Trend of South Texas. The
         Company was incorporated in June 1982. The Company, which was owned by
         the stockholders of Michael Holdings, Inc. ("MHI"), became a
         wholly-owned subsidiary of MHI on July 1, 1996 in a transaction
         accounted for at historical cost as a reorganization of entities under
         common control.

         The Company was merged with and into Michael Gas Production Company
         ("MGPC"), which was also a wholly-owned subsidiary of MHI. Following
         the merger, MGPC changed its name to MPC. This transaction was
         accounted for at historical cost as a reorganization of entities under
         common control. The financial statements reflect the financial
         position, results of operations and cash flows of the combined
         companies for all periods presented as if the merger had occurred on
         December 31, 1994. All significant intercompany transactions have been
         eliminated.

         CASH AND CASH EQUIVALENTS

         Cash equivalents consist of short-term highly liquid investments that
         have an original maturity of three months or less. The Company
         maintains its cash primarily with one financial institution located in
         Houston, Texas. The Company periodically assesses the financial
         condition of the institution and believes that any possible credit risk
         is minimal.

         OIL AND GAS PROPERTIES

         The Company follows the successful efforts method of accounting for its
         oil and gas properties. Under this method of accounting, all property
         acquisition costs and costs of exploratory and development wells are
         capitalized when incurred, pending determination of whether the well
         has found proved reserves. If an exploratory well has not found proved
         reserves, the costs of drilling the well are charged to expense. The
         costs of development wells are capitalized whether productive or
         nonproductive.

         Geological and geophysical costs on exploratory prospects and the costs
         of carrying and retaining unproved properties are expensed as incurred.
         An impairment allowance is provided to the extent that capitalized
         costs of unproved properties, on a property-by-property basis, are
         considered to be not realizable.

         OIL AND GAS AND OTHER PROPERTIES, CONTINUED

   
         Depletion, depreciation and amortization ("DD&A") of development costs
         and acquisition costs of proved oil and gas properties is provided
         using the units-of-production method based on proved developed reserves
         and proved reserves, respectively. The computation of DD&A takes into
         consideration restoration, dismantlement and abandonment costs and the
         anticipated proceeds from equipment salvage. The estimated restoration,
         dismantlement and abandonment costs are expected to be offset by the
         estimated residual value of lease and well equipment.
    

         Gains and losses are recognized on sales of entire interests in proved
         and unproved properties. Sales of partial interests are generally
         treated as recoveries of costs.

         IMPAIRMENT OF OIL AND GAS PROPERTIES

         Effective January 1, 1996, the Company adopted Statement of Financial
         Accounting Standards ("SFAS") No. 121 which requires that long-lived
         assets held and used by an entity be reviewed for impairment whenever
         events or changes indicate that the net book value of the asset may not
         be recoverable. The net book value of an asset is reduced to fair value
         if the sum of expected undiscounted future net cash flows from the use
         of the asset is less than the net book value of the asset. Under SFAS
         No. 121, the Company evaluates impairment of its oil and gas properties
         on a field basis. The Company recorded impairment losses of $156,000
         and $238,000 during the years ended December 31, 1996 and 1997,
         respectively, which is included in DD&A. Prior to the adoption of SFAS
         No. 121, the Company recognized an impairment loss if the Company's
         total net capitalized costs exceeded the sum of expected undiscounted
         future net cash flows.

         NATURAL GAS BALANCING

         The Company incurs natural gas production volume imbalances in the
         ordinary course of business on jointly owned properties. The Company
         follows the sales method to account for such imbalances. Under this
         method, revenue is recorded based on the Company's net revenue interest
         in production taken for delivery. The Company records a liability if
         its sales of gas volumes in excess of its entitlements from a jointly
         owned reservoir exceed its interest in the remaining estimated natural
         gas reserves of such reservoir. Volumetric production is monitored to
         minimize imbalances, and such imbalances were not significant at
         December 31, 1996 and 1997.

         INCOME TAXES

         Through June 30, 1996, the Company was taxed under the provisions of
         "Subchapter S" of the Internal Revenue Code, which provides that the
         individual shareholders are liable for federal income taxes on the
         Company's taxable income. Accordingly, no provision for federal income
         taxes is reflected in the statement of operations for periods ending
         prior to June 30, 1996. Effective July 1, 1996, the Company began
         filing a consolidated federal income tax return with MHI.

         Deferred income taxes are provided to reflect the tax consequences in
         future years of differences between the financial statement and tax
         bases of assets and liabilities. Tax credits are accounted for under
         the flow-through method, which reduces the provision for income taxes
         in the year the tax credits are earned. A valuation allowance is
         established to reduce deferred tax assets if it is more likely than not
         that the related tax benefits will not be realized. The Company
         calculates current and deferred taxes on an individual company basis.

         PRICE RISK MANAGEMENT ACTIVITIES

         The Company periodically uses swap contracts to hedge or otherwise
         reduce the impact of natural gas price fluctuations. Gains and losses
         resulting from changes in the market value of the financial instruments
         utilized as hedges are deferred and recognized in the statement of
         operations, together with the gain or loss on the hedged transaction,
         as the physical production is sold under the relevant contracts. Cash
         flows resulting from the Company's risk management activities are
         classified in the accompanying statement of cash flows in the same
         category as the item being hedged.

         These instruments are measured for effectiveness on an enterprise basis
         both at the inception of the contract and on an ongoing basis. If these
         instruments are terminated prior to maturity, resulting gains or losses
         continue to be deferred until the hedged item is recognized in income.

         In connection with these hedging transactions, the Company may be
         exposed to nonperformance by other parties to such agreements, thereby
         subjecting the Company to current natural gas prices. However, the
         Company only enters into hedging contracts with large financial
         institutions and does not anticipate nonperformance.

         CONCENTRATION OF CREDIT RISK

         Substantially all of the Company's receivables are within the oil and
         gas industry, primarily from purchasers of oil and gas and joint
         venture participants. Collectibility is dependent upon the general
         economic conditions of the purchasers and the oil and gas industry. The
         receivables are not collateralized and to date, the Company has had
         minimal bad debts.

         FAIR VALUE OF FINANCIAL INSTRUMENTS

         The carrying amounts reported in the balance sheet for cash and cash
         equivalents, receivables, and accounts payable approximate their fair
         value. The carrying value of the Company's long-term debt approximates
         fair market value as the debt accrues interest at variable rates which
         approximate market conditions. The fair value of derivative financial
         instruments is estimated using current market quotes.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of revenues
         and expenses during the reporting period. The Company's most
         significant estimates relate to the assessment of impairment of proved
         and unproved oil and gas properties, depreciation, depletion, and
         amortization expense, and proved oil and gas reserves (see Note 13).
         Actual results could differ from these estimates.
      
   
         UNAUDITED FINANCIAL STATEMENTS

         In the opinion of management, the accompanying unaudited financial
         statements contain all adjustments necessary to present fairly the
         financial position of the Company as of March 31, 1998 and the results
         of operations and cash flows for the periods presented.  All such
         adjustments are of normal recurring nature.  Certain information and
         footnote disclosures normally included in financial statements
         prepared in accordance with generally accepted accounting principles
         have been condensed or omitted pursuant to the SEC's rules and
         regulations.  The results of operations for the periods presented are
         not necessarily indicative of the results for the full year.   
    

2.       OIL AND GAS PROPERTY TRANSACTIONS:

         In August 1996, the Company acquired oil and gas properties for
         approximately $11.8 million in cash, net of post closing adjustments
         totaling $420,000 which were received in 1997. Accordingly, revenues
         and expenses from the properties have been included in the Company's
         statement of operations from the date of purchase. The pro forma
         results of operations, assuming the properties were acquired on January
         1 of each respective year are as follows (in thousands):

         T.E.P. FINANCING

         On August 13, 1996, the Company entered into a comprehensive credit
         agreement (the "T.E.P. Financing") with a limited partnership. Under
         the T.E.P. Financing, total available credit amounted to approximately
         $42.2 million, of which $16.3 million was available for oil and gas
         property acquisitions and $25.9 million for development costs. As of
         December 31, 1997, $14 million was available for future property
         acquisitions and development costs. The T.E.P. Financing expires August
         12, 2001.

         T.E.P. FINANCING, CONTINUED

         The Company utilized loan proceeds of approximately $14.9 million to
         acquire proved oil and gas properties located in South Texas (the "Lobo
         Properties"). Through December 31, 1996 and 1997, loan proceeds of
         approximately $1.8 million and $11.8 million, respectively, have been
         used to develop those properties. In conjunction with entering into the
         T.E.P. Financing, the Company conveyed to an affiliate of the lender a
         net profits interest in all of the Company's oil and gas properties,
         including the acquired properties ("Net Profits Interest"). The Net
         Profits Interest grants the affiliate 30% of the net profits, as
         defined, beginning the earlier of August 12, 2001, or the date of
         repayment of all amounts due and occurring pursuant to the T.E.P.
         Financing. The Net Profits Interest reduces to 15% of the net profits,
         as defined, after payment of $10,000,000 pursuant to the interest. As
         part of the T.E.P. Financing, the Company also granted to the lender a
         warrant to purchase up to five percent of the Company's common stock at
         an exercise price of $625 per share until August 12, 2001. The value
         assigned to the Net Profits Interest and warrant was recorded as a
         discount to the loan proceeds.

         Under the terms of the T.E.P. Financing, principal is payable as a
         percentage of net revenue, as defined. As of December 31, 1996 and
         1997, the Company had repaid approximately $63,000 and $2.9 million of
         principal under the T.E.P. Financing, respectively. Interest is payable
         monthly and accrues at a combination of LIBOR plus 4.5% and New York
         prime plus certain basis points based on the specific borrowing. At
         December 31, 1996 and 1997, the blended effective interest rate
         accruing on the loans was 14% and 15%, respectively. The loan is
         collateralized by the oil and gas properties and the stock of the
         Company.

         The T.E.P. Financing contains financial covenants, the most restrictive
         of which pertain to the payment of dividends, distributions to
         shareholders and the Company's working capital ratio. The T.E.P.
         Financing also contains administrative covenants. Except for violations
         of certain administrative covenants during the years ended December 31,
         1996 and 1997, the Company was in compliance with the covenants of the
         T.E.P. Financing. Regarding the violations of such administrative
         covenants, the Company obtained a waiver from the lender of the T.E.P.
         Financing which agreed not to assert any default based upon such
         violations unless they exist after April 15, 1998. The Company plans to
         use proceeds from the Private Placement (see Note 12) to repay the
         outstanding borrowings under the T.E.P. Financing and repurchase the
         Net Profits Interest for $11 million. Upon repayment of the borrowings
         under the T.E.P. Financing, the lender will cancel the warrants.

         NOTES PAYABLE TO A LIMITED PARTNERSHIP

         In August 1996, the Company utilized $2.0 million of the T.E.P.
         Financing loan proceeds to pay down certain notes payable to a limited
         partnership. The remaining balance on the notes payable of $4.9
         million, including accrued interest, was paid through the transfer of
         oil and gas properties with a net book value of $4.7 million, resulting
         in a gain on the sale of approximately $182,000.

         At December 31, 1997, the Company had a net operating loss carryforward
         of approximately $9.3 million, which begins expiring in 2017.
         Utilization of the net operating loss carryforward is subject to annual
         limitations due to certain stock ownership changes that have occurred
         or may occur. The Company does not believe a deferred tax asset
         valuation allowance is necessary at December 31, 1997 as all tax
         carryforwards are expected to be fully utilized.

         For the year ended December 31, 1995, the Company was not subject to
         federal income taxes (see Note 1) and had a state tax benefit totaling
         $79,000.

         Income tax expense differs from the amount that would be provided by
         applying the statutory U.S. federal income tax rate to (loss) income
         before income taxes for the following reasons (in thousands):

5.       HEDGING ACTIVITIES:

         In 1996, in conjunction with the T.E.P. Financing, the Company entered
         into a gas swap contract to hedge or otherwise reduce the impact of
         natural gas price fluctuations for other than trading purposes. Under
         the terms of the swap agreement, the Company is a fixed-price receiver
         on approximately 89,000 Mmbtu per month from January 1998 through
         August, 2001. The Swap Agreement covered approximately 72% of the
         Company's 1997 natural gas volumes. The average fixed price under the
         agreement is $1.90 per Mmbtu. The estimated fair value of the swap
         agreement was approximately $(1.1 million) at December 31, 1996 and
         1997. This swap contract reduced natural gas revenues by approximately
         $313,000 and $1.2 million for the years ended December 31, 1996 and
         1997, respectively. The Company is exposed to credit-related losses in
         the event of nonperformance by the counterparty, but it does not expect
         the counterparty to fail to meet its obligations based on existing
         credit ratings (See Note 12).

6.       EMPLOYEE BENEFIT PLAN:

         The Company sponsors a 401(k) profit sharing plan (the "401(k) Plan")
         under Section 401(k) of the Internal Revenue Code ("IRS"). This plan
         covers all employees of the Company. The Company, at its discretion,
         matches $1.00 for each $1.00 of employee deferral, with the Company's
         contribution not to exceed 8% of an employee's salary, subject to
         limitations imposed by the IRS. The Company did not make any
         contributions to the 401(k) Plan during the years ended December 31,
         1995, 1996 and 1997.

7.       DISCONTINUED OPERATIONS:

         At January 1, 1995, the Company owned a 50% equity interest in two non
         oil and gas limited liability companies which were accounted for under
         the equity method. On January 20, 1995, the Company obtained a loan of
         $2 million from a private lender, the proceeds of which were used to
         pay trade obligations. The note provided for interest at 6% above the
         reference prime rate. As consideration for making the loan, a 5%
         interest in the Company's ownership in the two limited liability
         companies was transferred to the lender. The net book value which
         approximated fair value of the interest transferred of $100,000 was
         recorded as interest expense. The note was collateralized by the
         Company's entire interest in the two limited liability companies.

         In April 1995, the Company sold a 42% equity interest in each of the
         limited liability companies to the private lender for cash proceeds of
         approximately $1.2 million plus repayment of the remaining principal
         balance of $1.75 million on the loan discussed above, resulting in a
         gain of approximately $2.1 million (net of state income taxes of
         $96,000). In September 1995, the Company distributed all of its 
         remaining interest in each of the limited liability companies to its
         stockholders. The distribution was recorded at the net book value of
         $134,000. The Company's investment in these two companies has been
         accounted for as a discontinued operation.
    


8.       RELATED PARTY TRANSACTIONS:

         Beginning in April 1996, the Company entered into a two year agreement,
         continuing thereafter on a quarterly basis subject to termination by
         either party, with Upstream Energy Corporation ("Upstream") whereby
         Upstream purchases all of the gas produced by the Company at spot
         market prices. Under the terms of the agreement, the Company pays
         Upstream a marketing fee of $.03 per Mmbtu which totaled approximately
         $57,000, $106,000, and $220,000 for the years ended December 31, 1995,
         1996, and 1997, respectively. During the years ended December 31, 1995,
         1996 and 1997, Upstream purchased gas produced by the Company for
         approximately $668,000, $3.2 million and $9.7 million, respectively. At
         December 31, 1996 and 1997, receivables from Upstream of approximately
         $2.1 million and $3.9 million, respectively, were included in accrued
         oil and gas sales in the balance sheet. The chief executive officer of
         the Company had an ownership interest in Upstream until August, 1997.
         The Company believes the revenues received were equivalent to those
         that would be paid under an arms-length transaction in the normal
         course of business.

         In July 1997, the Company executed in writing a ten year old verbal
         agreement which granted to the Vice President of Exploration of the
         Company a 1.5% of 8/8ths overriding royalty interest in leases acquired
         either directly or indirectly by the Company or its affiliates in Webb
         County or Zapata County, Texas. This overriding royalty interest
         expires upon the death of the vice president or upon his termination,
         resignation or retirement from the Company. The overriding royalty
         interest does not apply to any producing properties acquired by the
         Company except for deepenings or sidetracks of existing wells and/or
         all new wells drilled on the acquired producing properties.

         During the year ended December 31, 1995, the Company distributed its
         overriding royalty interest in certain oil and gas properties to the
         stockholders. The distribution was recorded at the net book value of
         $60,000.

         From May to July of 1995 the Company made loans to the Chairman of the
         Board and Chief Executive Officer of the Company, in an aggregate
         principal amount of $314,700. Interest on the indebtedness accrued at a
         rate of 5% per annum and $302,055 of such indebtedness was repaid to
         the Company in December 1995. The remaining balance, together with
         interest, was paid in May 1997.

         Rent expense for the years ended December 31, 1995, 1996 and 1997 was

         (See Note 12).
    

         LEGAL PROCEEDINGS

         The Company has been and may in the future be involved as a party in
         various legal proceedings, which are incidental to the ordinary course
         of business. Management regularly analyzes current information and, as
         necessary, provides accruals for probable liabilities on the eventual
         disposition of these matters. In the opinion of management and legal
         counsel, as of December 31, 1997, there were no threatened or pending
         legal matters which would have a material impact on the Company's
         results of operations, financial position or cash flows.

         YEAR 2000

   
         The Company has reviewed its computer systems and hardware to locate
         potential operational problems associated with the year 2000 issue. The
         Company believes that all year 2000 problems in its internal
         information processing computer systems have been resolved and have not
         caused and will not cause disruption of its operations, or have a
         material adverse effect on its financial condition or results of
         operations. The Company is in the process of contacting and receiving
         verification of year 2000 issue compliance from its vendors,
         purchasers, suppliers, transporters of its production and its financial
         service providers. At this time, the Company does not anticipate any
         material disruption in its operations as a result of any year 2000
         compliance issues, but will continue to monitor the situation with
         third parties.
    

11.      RECENT ACCOUNTING PRONOUNCEMENTS:

   
         In June 1997, the Financial Accounting Standards Board ("FASB") issued
         SFAS No. 130, Reporting Comprehensive Income, which is effective for
         fiscal years beginning after December 15, 1997. SFAS No. 130
         establishes standards for reporting and display of comprehensive income
         and its components (revenues, expenses, gains and losses) in a full set
         of general-purpose financial statements. It requires (a) classification
         of items of other comprehensive income by their nature in a financial
         statement and (b) display of the accumulated balance of other
         comprehensive income separate from retained earnings and additional
         paid-in capital in the equity section of a statement of financial
         position. The adoption of SFAS No. 130 did not have a material effect
         on the Company's financial position, results of operations or cash
         flows. (See Note 12 -- Recent Accounting Pronouncements).

NOTES TO FINANCIAL STATEMENTS, CONTINUED



   
         In June 1997, the FASB issued SFAS No. 131, Disclosures about
         Segments of an Enterprise and Related Information, which is effective
         for fiscal years beginning after December 15, 1997. SFAS No. 131
         establishes standards for reporting information about operating
         segments in annual financial statements and requires selected
         information about operating segments in interim financial reports
         issued to shareholders. It also establishes standards for related
         disclosures about products and services, geographic areas and major
         customers. This statement supersedes SFAS No. 14, Financial Reporting
         for Segments of a Business Enterprise, but retains the requirement to
         report information about major customers. Because the Company operates
         in only one segment, management does not expect the adoption of SFAS
         No. 131 to have a material affect on the Company's financial statement
         disclosures.
    

   
         In March 1998, the FASB issued SFAS No. 132, Employers' Disclosures
         about Pensions and Other Postretirement Benefits, which is effective
         for fiscal years beginning after December 15, 1997. SFAS No. 132
         revises employers' disclosures about pension and other postretirement
         benefit plans. It standardizes the disclosure requirements for pensions
         and other postretirement benefits to the extent practicable, requires
         additional information on changes in the benefits obligations and fair
         values of plan assets that will facilitate financial analysis, and
         eliminates certain disclosures that are no longer as useful as they
         were when SFAS No. 87, Employers' Accounting for Pensions, and SFAS No.
         88, Employers' Accounting for Settlements and Curtailments of Deferred
         Benefit Pension Plans and for Termination Benefits, were issued.
         Because the Company does not currently have pension or other
         postretirement benefits, management does not expect the adoption of
         SFAS No. 132 to have a material affect on the Company's financial
         statement disclosures.
    

   
    

12.      SUBSEQUENT EVENTS:

         PRIVATE PLACEMENT

         On April 2, 1998, the Company issued $135 million of senior notes (the
         "Notes") at a discount of 1.751% in a transaction exempt from
         registration under federal and state securities laws (the "Offering").
         The Notes mature in April 2005 and bear interest at a rate of
         approximately 11.5% per annum, payable semi-annually in April and
         October of each year, commencing October 1998. The Notes are redeemable
         at the option of the Company, in whole or in part, at any time after
         April 2003, at specified redemption prices, plus accrued and unpaid
         interest and liquidated damages, as defined. The Company is required to
         comply with certain covenants, which limit, among other things, the
         ability of the Company to incur additional indebtedness, pay dividends,
         repurchase equity interests, sell assets or enter into mergers and
         consolidations.

         The Company completed the acquisitions discussed below with proceeds
         from the Offering.

         ENRON ACQUISITION

         On February 5, 1998, the Company entered into a purchase and sale
         agreement with Enron Oil & Gas Company ("Enron") (the "Enron
         Acquisition"). The purchase and sale agreement provides that Enron will
         convey to the Company interests in certain oil and natural gas leases
         in Webb County, Hidalgo County and Zapata County, Texas, and all
         seismic data owned by Enron covering the properties. The Enron
         Acquisition was closed on March 31, 1998.

         The purchase price for the Enron Acquisition was $45.8 million, subject
         to post-closing adjustments, and the conveyance by the Company to Enron
         of all of the Company's interests in certain oil and natural gas
         properties in Webb County, Texas. The purchase price was paid in the
         form of a promissory note dated March 31, 1998 bearing an interest rate
         of 8% per annum and maturing on April 2, 1998. The Company utilized a
         portion of the net proceeds of the Offering to repay the promissory
         note.

         CONOCO ACQUISITION

         On February 20, 1998, the Company entered into a purchase and sale
         agreement with Conoco Inc. ("Conoco") (the "Conoco Acquisition"). The
         purchase and sale agreement provides that Conoco will convey to the
         Company certain oil and natural gas leases covering approximately
         39,000 acres in Webb County, Texas. On April 2, 1998, the Company paid
         $22.5 million, subject to post-closing adjustments, as consideration
         for the rights and property conveyed by Conoco as described above.

         LOBO LEASE ACQUISITION

         On April 20, 1998, the Company entered into a lease with Mobil
         effective as of January 1, 1998 covering Mobil's interest in
         approximately 40,000 acres in the Lobo Trend (the "Lobo Lease").
         Consideration for the Lobo Lease is in the form of future deliveries of
         4 Bcf of gas, commencing May 1, 1998 and terminating December 31, 1998.
         On April 23, 1998, the Company entered into a contract to secure
         delivery of this volume of gas for consideration of $9.98 million.

         LINE OF CREDIT

   
         On May 15, 1998, the Company executed a credit agreement with
         Christiania Bank og KreditKasse ("Christiania"), for a new reducing
         revolving credit facility (the "Credit Facility") which provides for a
         maximum loan amount of $50 million with an initial borrowing base of
         $30 million. Under the Credit Facility, the principal outstanding will
         be due and payable in May 2002 with interest payable monthly. The
         interest rate for borrowings will be calculated at the Eurodollar Rate
         plus 1.75% or ABR rate at the election of the Company. The ABR rate is
         the highest of (i) the interest rate publicly announced by Christiania,
         (ii) the secondary market rate for three-month certificates of deposit
         plus 1% and (iii) the federal funds rate plus 0.5%. The Credit Facility
         is collateralized by virtually all of the Company's oil and natural 
         gas properties.

         HEDGE CONTRACTS

         The Company terminated the gas swap agreement discussed in Note 5 on
         April 2, 1998 for a cash payment of $1.8 million.

   
         During April 1998, the Company purchased a gas put option with a strike
         price of $2.25 per Mmbtu for approximately $230,000. The put option has
         a notional volume of 150,000 Mmbtu per month from May 1, 1998 to April
         30, 1999. The Company also entered into a collar contract with a floor
         price of $2.25 per Mmbtu and a ceiling price of $2.99 per Mmbtu. The
         collar has a notional volume of 450,000 Mmbtu per month from May 1,
         1998 to April 30, 1999.
    

         LEASES
          
   
         On May 1, 1998, the Company executed an amendment to the noncancelable
         operating lease agreement (See Note 10) to acquire additional office
         space and extend the lease term for three years. The extended lease
         term expires in 2004 and increases noncancelable lease commitments by
         approximately $2,200 per month from July 31, 1998 through April 30,
         2001 and by approximately 3,700 per month from May 1, 2001 through
         June 30, 2004. The amended lease has two options to renew the lease for
         a period of five years each. 
    

   
         RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the FASB issued SFAS No. 133, Accounting for
         Derivative Instruments and Hedging Activities, which is effective for
         fiscal years beginning after June 15, 1999. SFAS No. 133 establishes
         accounting and reporting standards for derivative instruments,
         including certain derivative instruments embedded in other contracts,
         and for hedging activities. It also requires that an entity recognize
         all derivatives as either assets or liabilities in the statement of
         financial position and measure those items at fair value. If certain
         conditions are met, a derivative may be specifically designated as (a)
         a hedge of the exposure to changes in the fair value of a recognized
         asset or liability or an unrecognized firm commitment, (b) a hedge of
         the exposure to variable cash flows of a forecasted transaction, or (c)
         a hedge of the foreign currency exposure of a net investment in a
         foreign operation, an unrecognized firm commitment, an
         available-for-sale security, or a foreign-currency-denominated
         forecasted transaction.
    

   
         As discussed in Note 5 to the Financial Statements, the company has
         historically hedged a portion of its future gas production using gas
         swap contracts. These contracts are a hedge of the Company's exposure
         to the variability of future cash flows due to potential decreases in
         gas prices. For a derivative designated as hedging the exposure to
         variable cash flows of a forecasted transaction (referred to as a cash
         flow hedge), the effective portion of the derivative gain or loss is
         initially reported as a component of other comprehensive income
         (outside earnings) and subsequently reclassified into earnings when the
         forecasted transaction affects earnings. The ineffective portion of the
         gain or loss is reported in earnings immediately. The extent of the
         impact of adopting SFAS #133 on the Company's financial position,
         results of operations, or cash flows will be a function of the open
         derivative contracts at the date of adoption. If the Company had
         adopted the standard as of March 31, 1998, the Company would have
         recorded an unrealized loss of approximately $1.2 million (net of tax)
         as a component of other comprehensive income.

         OIL AND GAS RESERVE QUANTITIES (UNAUDITED)

         Users of this information should be aware that the process of
         estimating quantities of "proved" and "proved developed" natural gas
         and crude oil reserves is very complex, requiring significant
         subjective decisions in the evaluation of all available geological,
         engineering and economic data for each reservoir. The data for a given
         reservoir may also change substantially over time as a result of
         numerous factors including, but not limited to, additional development
         activity, evolving production history and continual reassessment of the
         viability of production under varying economic conditions.
         Consequently, material revisions to existing reserve estimates occur
         from time to time. Although every reasonable effort is made to ensure
         that reserve estimates reported represent the most accurate assessments
         possible, the significance of the subjective decisions required and
         variances in available data for various reservoirs make these estimates
         generally less precise than other estimates presented in connection
         with financial statement disclosures.

         The reserve information as of December 31, 1994 and 1995 was prepared
         by Mohajir & Associates, Inc. The reserve information as of December
         31, 1996 and 1997 was prepared by Huddleston & Co., Inc. The Company
         emphasizes that reserve estimates are inherently imprecise and that
         estimates of new discoveries are more imprecise than those of proved
         producing oil and gas properties. Accordingly, these estimates are
         expected to change as future information becomes available.

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

         No major discovery or other favorable or adverse event subsequent to
         December 31, 1997 is believed to have caused a material change in the
         estimates of proved or proved developed reserves as of that date.

         The following table sets forth the Company's net proved reserves,
         including the changes therein, and proved developed reserves (all
         within the United States) at the end of each of the three years in the
         period ended December 31, 1997:

         STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO
         PROVED OIL AND GAS RESERVES (UNAUDITED)

         SFAS No. 69 prescribes guidelines for computing a standardized measure
         of future net cash flows and changes therein relating to estimated
         proved reserves. The Company has followed these guidelines which are
         briefly discussed below.

NOTES TO FINANCIAL STATEMENTS, CONTINUED



         Future cash inflows and future production and development costs are
         determined by applying year-end prices and costs to the estimated
         quantities of oil and gas to be produced. Estimated future income taxes
         are computed using current statutory income tax rates, including
         consideration for estimated future statutory depletion and alternative
         fuels tax credits. The resulting future net cash flows are reduced to
         present value amounts by applying a 10% annual discount factor.

         The assumptions used to compute the standardized measure are those
         prescribed by the Financial Accounting Standards Board and, as such do
         not necessarily reflect the Company's expectations of actual revenues
         to be derived from those reserves nor their present worth. The
         limitations inherent in the reserve quantity estimation process, as
         discussed previously, are equally applicable to the standardized
         measure computations since these estimates are the basis for the
         valuation process.

         The standardized measure of discounted future net cash flows relating
         to proved oil and gas reserves is as follows (in thousands):

REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholder of
Michael Petroleum Corporation:

We have audited the accompanying statement of revenues and direct operating
expenses of the Enron Properties for the years ended December 31, 1996 and 1997.
This financial statement is the responsibility of the Company's management. Our
responsibility is to express an opinion on this financial statement 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 statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. 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.

The accompanying financial statement reflects the revenues and direct operating
expenses of the Enron Properties as described in Note 1 and is not intended to
be a complete presentation of the financial position, results of operations or
cash flows of the Enron Properties.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the revenues and direct operating expenses of the Enron
Properties as described in Note 1 for the years ended December 31, 1996 and 1997
in conformity with generally accepted accounting principles.

THE ENRON PROPERTIES
NOTES TO FINANCIAL STATEMENT


1.       BASIS OF PRESENTATION:

         The accompanying financial statement reflects the revenues and direct
         operating expenses relating to certain oil and gas properties located
         in South Texas (the "Enron Properties").

         The historical financial statements reflecting financial position,
         results of operations and cash flows required by generally accepted
         accounting principles are not presented, as such information is neither
         readily available on an individual property basis nor meaningful for
         the properties. During the periods presented, the Enron Properties were
         not accounted for as a separate entity. This financial statement does
         not include depreciation, depletion and amortization, general and
         administrative, interest or federal income tax expense. Accordingly,
         the accompanying financial statement is not intended to represent the
         financial position, results of operations or cash flows in conformity
         with generally accepted accounting principles. This financial statement
         may not be representative of future operations.

   
2.       INTERIM FINANCIAL INFORMATION:

         The accompanying financial information for the three-month periods 
         ended March 31, 1997 and 1998 is unaudited but reflects, in the
         opinion of the Company's management, all adjustments (which include
         only normal recurring adjustments) necessary to present fairly the
         revenues and direct operating expenses of the Enron Properties for
         such periods. The revenues and direct operating expenses for such
         interim periods are not necessarily indicative of results to be
         expected for the full year.

THE ENRON PROPERTIES
SUPPLEMENTARY FINANCIAL INFORMATION
SUPPLEMENTARY OIL AND GAS DISCLOSURES (UNAUDITED)


OIL AND GAS RESERVE QUANTITIES

Users of this information should be aware that the process of estimating
quantities of "proved" and "proved developed" natural gas and crude oil reserves
is very complex, requiring significant subjective decisions in the evaluation of
all available geological, engineering and economic data for each reservoir. The
data for a given reservoir may also change substantially over time as a result
of numerous factors including, but not limited to, additional development
activity, evolving production history and continual reassessment of the
viability of production under varying economic conditions. Consequently,
material revisions to existing reserve estimates occur from time to time.
Although every reasonable effort is made to ensure that reserve estimates
reported represent the most accurate assessments possible, the significance of
the subjective decisions required and variances in available data for various
reservoirs make these estimates generally less precise than other estimates
presented in connection with financial statement disclosures.

The reserve information was prepared by the Company and Huddleston & Co., Inc.
The Company emphasizes that reserve estimates are inherently imprecise and that
estimates of new discoveries are more imprecise than those of proved producing
oil and gas properties. Accordingly, these estimates are expected to change as
future information becomes available.

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

ESTIMATED NET QUANTITIES OF OIL AND GAS RESERVES ATTRIBUTED TO THE ENRON
PROPERTIES

No major discovery or other favorable or adverse event subsequent to December
31, 1997 is believed to have caused a material change in the estimates of proved
or proved developed reserves as of that date.

The following table sets forth the net proved reserves, including the changes
therein, and proved developed reserves (all within the United States) at the end
of each of the two years in the period ended December 31, 1997:

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVES

SFAS No. 69 prescribes guidelines for computing a standardized measure of future
net cash flows and changes therein relating to estimated proved reserves. The
Company has followed these guidelines which are briefly discussed below. 

Future cash inflows and future production and development costs are determined
by applying year-end prices and costs to the estimated quantities of oil and gas
to be produced. The resulting future net cash flows are reduced to present value
amounts by applying a 10% annual discount factor.

The assumptions used to compute the standardized measure are those prescribed by
the Financial Accounting Standards Board and, as such do not necessarily reflect
the Company's expectations of actual revenues to be derived from those reserves
nor their present worth. The limitations inherent in the reserve quantity
estimation process, as discussed previously, are equally applicable to the
standardized measure computations since these estimates are the basis for the
valuation process.

THE CONOCO PROPERTIES
NOTES TO FINANCIAL STATEMENT


1.       BASIS OF PRESENTATION:

         The accompanying financial statement reflects the revenues and direct
         operating expenses relating to certain oil and gas properties located
         in South Texas (the "Conoco Properties").

         The historical financial statements reflecting financial position,
         results of operations and cash flows required by generally accepted
         accounting principles are not presented, as such information is neither
         readily available on an individual property basis nor meaningful for
         the properties. During the periods presented, the Conoco Properties
         were not accounted for as a separate entity. The financial statement
         does not include depreciation, depletion and amortization, general and
         administrative, interest or federal income tax expenses. Accordingly,
         the accompanying financial statement is not intended to represent the
         financial position, results of operations or cash flows in conformity

2.       INTERIM FINANCIAL INFORMATION:

         The accompanying financial information for the three-month periods
         ended March 31, 1997 and 1998 is unaudited but reflects, in the opinion
         of the Company's management, all adjustments (which include only normal
         recurring adjustments) necessary to present fairly the revenues and
         direct operating expenses of the Conoco Properties for such periods.
         The revenues and direct operating expenses for such interim periods are
         not necessarily indicative of results to be expected for the full year.

OIL AND GAS RESERVE QUANTITIES

Users of this information should be aware that the process of estimating
quantities of "proved" and "proved developed" natural gas and crude oil reserves
is very complex, requiring significant subjective decisions in the evaluation of
all available geological, engineering and economic data for each reservoir. The
data for a given reservoir may also change substantially over time as a result
of numerous factors including, but not limited to, additional development
activity, evolving production history and continual reassessment of the
viability of production under varying economic conditions. Consequently,
material revisions to existing reserve estimates occur from time to time.
Although every reasonable effort is made to ensure that reserve estimates
reported represent the most accurate assessments possible, the significance of
the subjective decisions required and variances in available data for various
reservoirs make these estimates generally less precise than other estimates
presented in connection with financial statement disclosures.

The reserve information was prepared by the Company and Huddleston & Co., Inc.
The Company emphasizes that reserve estimates are inherently imprecise and that
estimates of new discoveries are more imprecise than those of proved producing
oil and gas properties. Accordingly, these estimates are expected to change as
future information becomes available.

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

ESTIMATED NET QUANTITIES OF OIL AND GAS RESERVES ATTRIBUTED TO THE CONOCO
PROPERTIES

No major discovery or other favorable or adverse event subsequent to December
31, 1997 is believed to have caused a material change in the estimates of proved
or proved developed reserves as of that date.

The following table sets forth the net proved reserves, including the changes
therein, and proved developed reserves (all within the United States) at the end
of each of the two years in the period ended December 31, 1997:

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVES

SFAS No. 69 prescribes guidelines for computing a standardized measure of future
net cash flows and changes therein relating to estimated proved reserves. The
Company has followed these guidelines which are briefly discussed below.

Future cash inflows and future production and development costs are determined
by applying year-end prices and costs to the estimated quantities of oil and gas
to be produced. The resulting future net cash flows are reduced to present value
amounts by applying a 10% annual discount factor.

The assumptions used to compute the standardized measure are those prescribed by
the Financial Accounting Standards Board and, as such do not necessarily reflect
the Company's expectations of actual revenues to be derived from those reserves
nor their present worth. The limitations inherent in the reserve quantity
estimation process, as discussed previously, are equally applicable to the
standardized measure computations since these estimates are the basis for the
valuation process.

REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholder of
Michael Petroleum Corporation:

We have audited the accompanying statement of revenues and direct operating
expenses of the Lobo Properties for the year ended December 31, 1995 and the
seven-month period ended July 31, 1996. This financial statement is the
responsibility of the Company's management. Our responsibility is to express an
opinion on this financial statement 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 statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. 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.

The accompanying financial statement reflects the revenues and direct operating
expenses of the Lobo Properties as described in Note 1 and is not intended to be
a complete presentation of the financial position, results of operations or cash
flows of the Lobo Properties.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the revenues and direct operating expenses of the Lobo
Properties as described in Note 1 for the year ended December 31, 1995 and the
seven-month period ended July 31, 1996 in conformity with generally accepted
accounting principles.

NOTES TO FINANCIAL STATEMENT


1.       BASIS OF PRESENTATION:

         The accompanying financial statement reflects the revenues and direct
         operating expenses relating to certain oil and gas properties located
         in South Texas (the "Lobo Properties").

         The historical financial statements reflecting financial position,
         results of operations and cash flows required by generally accepted
         accounting principles are not presented, as such information is neither
         readily available on an individual property basis nor meaningful for
         the properties. During the periods presented, the Lobo Properties were
         not accounted for as a separate entity. This financial statement does
         not include depreciation, depletion and amortization, general and
         administrative, interest or federal income tax expenses. Accordingly,
         the accompanying financial statement is not intended to represent the
         financial position, results of operations or cash flows in conformity
         with generally accepted accounting principles. This financial statement
         may not be representative of future operations.

                                   PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
   

     Article 2.02-1 of the Texas Business Corporation Act (the "TBCA") permits
the Company, in certain circumstances, to indemnify any present or former
director, officer, employee or agent of the Company against judgments,
penalties, fines, settlements and reasonable expenses incurred in connection
with a proceeding in which any such person was, is or is threatened to be, made
a party by reason of holding such office or position, but only to a limited
extent for obligations resulting from a proceeding in which the person is found
liable on the basis that a personal benefit was improperly received or in
circumstances in which the person is found liable in a derivative suit brought
on behalf of the Company.

     The Articles of Incorporation of the Company (the "Articles of
Incorporation") provide that a director of the Company is not liable to the
Company or its shareholders for damages for an act or omission made in the
director's capacity as a director, except for (a) a breach of the director's
duty of loyalty to the Company or its shareholders; (b) an act or omission not
in good faith that involves intentional misconduct or a knowing violation of the
law; (c) a transaction from which the director received an improper benefit,
whether or not the benefit resulted from an action taken within the scope of the
director's office; (d) an act or omission for which the liability of a director
is expressly provided by statute; or (e) an act related to an unlawful stock
repurchase or payment of dividend.  The Articles of Incorporation further
provide that a director, officer, or member of a committee shall not be liable
for acts, if the TBCA excuses such persons from liability.

     The Company's Bylaws provide that the Company may indemnify any person who
was, is or is threatened to be made a named defendant or respondent in any
proceeding because the person is or was a director only if it is found that such
person (a) conducted him or herself in good faith; (b) reasonably believed (i)
in the case of conduct in an official capacity as a director of the Company,
that the conduct was in the Company's best interests, and (ii) in all other
cases, that the conduct was at least not opposed to the Company's best
interests; and (c) in the case of any criminal proceeding, had no reasonable
cause to believe the conduct was unlawful.  A director may not be indemnified
for a proceeding in which he or she shall have been found liable for willful
or intentional misconduct in the performance of such director's duty to the
Company, however if such director is found liable on the basis that personal
benefit was improperly received by him or her, or in which the director is found
liable to the Company, that person may be indemnified for reasonable expenses
actually incurred.

     Before the Company indemnifies a director, authorization must be made by
the Board of Directors by a majority vote of directors who are not named
defendants or respondents in the proceeding; if such quorum cannot be obtained,
then by a majority vote of a committee of the Board of Directors, which shall
consist solely of two or more directors who are not named defendants or
respondents in the proceeding, or by special legal counsel, or by the
shareholders.  If a director wishes to challenge a decision made by the
preceding procedure, such director may apply to a court of competent
jurisdiction.  If that court determines that the director is fairly and
reasonably entitled to indemnification in view of all the relevant
circumstances, whether or not such director has met the standard of conduct or
has been found liable as set forth above, the court may order such
indemnification as the court determines is proper and equitable. 

     The Bylaws mandate that a director who has been wholly successful, on the
merits or otherwise, in the defense of any proceeding in which the director is a
party because he or she is or was a director, shall be indemnified by the
Company against reasonable expenses incurred by the director in connection with
the proceeding. 
    


                                     II-1
<PAGE>   145
   
     Pursuant to the Company's Bylaws, reasonable expenses incurred by a
director, who was, is, or is threatened to be made a named defendant or
respondent to a proceeding may be paid or reimbursed by the Company in advance
of the final disposition of such proceeding and without the determination
specified above, after receipt by the Company of a written affirmation by the
director of such director's good faith belief that he or she has met the
standard of conduct necessary for indemnification by the Company as authorized
in the Bylaws, and a written undertaking by or on behalf of the director to
repay the amount paid or reimbursed if it shall ultimately be determined that
such director has not met that standard, or if it is ultimately determined that
indemnification of the director against expenses incurred by him or her in
connection with that proceeding is prohibited by the Bylaws.  The written
undertaking required above must be an unlimited general obligation of the
director but need not be secured and may be accepted without reference to
financial ability to make repayment. Any indemnification of, or advance of
expenses to a director in accordance with the Company's Bylaws must be reported
in writing to the shareholders with or before the notice or waiver of notice of
the next shareholders' meeting or with or before the next submission to
shareholders of a consent to action without a meeting pursuant to Section A,
Article 9.10 of the TBCA, and in any case, within the 12-month period
immediately following the date of the indemnification or advance.  

     The indemnification provided by the Company's Bylaws is not deemed
exclusive of any other rights to which those indemnified may be entitled under
any statute, including, but not limited to, Article 2.02-1 of the TBCA, any
agreement, insurance policy, vote of shareholders or disinterested directors or
otherwise, both as to action in their official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person;
provided, however, any such provision must be consistent with the Company's
Bylaws and the Company's Articles of Incorporation.    

     The Company's Bylaws provide that an officer of the Company and persons
who are not or were not officers, employees or agents of the Company but who
are or were serving at the request of the Company as a director, officer,
partner, venturer, proprietor, trustee, employee, agent or similar functionary
of another foreign or domestic corporation, partnership or joint venture, sole
proprietorship, trust, other enterprise, or employee benefit plan shall, in
most cases, be indemnified as a director and shall be entitled to the same
extent as a director to seek indemnification pursuant to the Bylaws and that the
Company may indemnify and advance expenses to an officer, employee or agent of
the Company to the same extent that it may do so to directors, unless limited
by the Articles of Incorporation.

     The Bylaws of the Company allow the Company to purchase and maintain
insurance or another arrangement on behalf of any person who is or was a
director, officer, employee or agent of the Company, or who is or as serving at
the request of the Company as a director, officer, partner, venturer,
proprietor, trustee, employee, agent or similar functionary of another foreign
or domestic corporation, partnership, joint venture, sole proprietorship, trust,
other enterprise or employee benefit plan, against any liability asserted
against such person and incurred by him or her in any such a capacity or arising
out of his or her status as such a person, whether or not the Company would have
the power to indemnify him or her against such liability under the provisions of
the TBCA or the Company's Bylaws. If the insurance or other arrangement is with
a person or entity that is not regularly engaged in the business of providing
insurance coverage, the insurance or arrangement may provide for a payment of a
liability with respect to which the Company would not have the power to
indemnify the person only if such coverage has been approved by the shareholders
of the Company.  Without limiting the power of the Company to procure or
maintain any kind of insurance or other arrangement, a Company may, for the
benefit of persons

    

                                      II-2

indemnified by the Company, (a) create a trust fund, (b) establish any form of
self-insurance, (c) secure its indemnity obligation by grant of a security
interest or other lien on the assets of the Company, or (d) establish a letter
of credit, guaranty, or surety arrangement.  The insurance or other arrangement
may be procured, maintained, or established within the Company or with any
insurer or other person deemed appropriate by the Board of Directors regardless
of whether all or part of the stock or other securities of the insurer or other
person are owned in whole or in part by the Company.

     MHI has entered into Indemnity Agreements with each of the directors of
MHI (who also serve as the directors of the Company), pursuant to which MHI has
agreed to indemnify each director to the fullest extent permitted under the
TBCA.  In addition, pursuant to the Indemnity Agreements, MHI shall advance
reasonable expenses incurred by each director under certain circumstances in
any proceeding in which each director was, is or is threatened to be named a
defendant.

ITEM 22.  UNDERTAKINGS.

    The undersigned Registrant hereby undertakes:

    (1) to file, during any period in which offers or sales are being made, 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 (the "Securities Act");

                 (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 hereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in this Registration Statement.  Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the
         estimated maximum offering range may be reflected in the form of
         prospectus filed with the Securities and Exchange Commission pursuant
         to rule 424(b) if, in the aggregate, the changes in volume and price
         represent no more than a 20% change in the maximum aggregate offering
         price set forth in the "Calculation of Registration Fee" table in this
         Registration Statement when it becomes effective;

                 (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;

         (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.

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

         The undersigned Registrant hereby undertakes to file an application
for the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Trust Indenture Act.

         The undersigned Registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this Registration Statement through
the date of responding to the request.

         The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in this Registration Statement when it became effective.

         Re:     Registration Statement on Form S-4; $135,000,000 Aggregate
                 Principal Amount of 11-1/2% Senior Notes due 2005.

Ladies and Gentlemen:

We have acted as special counsel for Michael Petroleum Corporation, a Texas
corporation (the "Company"), in connection with the proposed issuance by the
Company of $135,000,000 aggregate principal amount of 11-1/2% Senior Notes due
2005 (the "Notes") in exchange for an equivalent amount of the Company's
outstanding 11-1/2% Senior Notes due 2005 (the "Old Notes").  The terms of the
offer to exchange are described in the Registration Statement on Form S-4 (the
"Registration Statement") filed with the Securities and Exchange Commission for
the registration of the Notes under the Securities Act of 1933, as amended (the
"Act").  The Old Notes have been, and the Notes will be, issued pursuant to an
indenture dated as of April 2, 1998 (the "Indenture"), between the Company and
State Street Bank and Trust Company, as Trustee (the "Trustee").

In connection with the foregoing, we have examined the Indenture, the
Registration Statement and such corporate records and instruments of the
Company as we have deemed necessary or appropriate for purposes of this
opinion.

We are opining herein as to the effect on the proposed issuance of the Notes of
the federal laws of the United States, the laws of the State of Texas and the
laws of the State of New York.

                   Specific Limitations and Qualifications on
                 Opinions Regarding Enforceability of the Notes

The enforceability of the Notes is subject to the effects of (i) applicable
bankruptcy, insolvency, reorganization, moratorium, rearrangement, liquidation,
conservatorship or similar laws of general application now or hereafter in
effect relating to or affecting the rights or remedies of creditors generally,
and (ii) general equity principles (regardless of whether enforcement is sought
in a proceeding in equity or law).

We express no opinion as to the enforceability of provisions of the Notes to
the extent that such provisions: (i) state that any party's failure or delay in
exercising rights, powers, privileges or remedies under the Notes shall not
operate as a waiver thereof; (ii) purport to preclude the amendment, waiver,
release or discharge of obligations except by an instrument in writing; (iii)
purport to indemnify any person for (A) such person's
<PAGE>   2

Page 2
    


violations of federal or state securities laws or environmental laws, or (B)
any obligation to the extent such obligation arises from or is a result of such
person's own negligence; (iv) purport to establish or satisfy certain factual
standards or conditions; (v) purport to sever unenforceable provisions from the
Notes, to the extent that the enforcement of remaining provisions would
frustrate the fundamental intent of the parties to such instrument; (vi)
restrict access to legal or equitable remedies; or (vii) purport to waive any
claim arising out of, or in any way related to, the Notes.

We express no opinion as to: (i) whether a court would grant specific
performance or any other equitable remedy with respect to enforcement of any
provision contained in the Notes; or (ii) the enforceability of any provision
contained in the Indenture relating to the appointment of a receiver, to the
extent that appointment of a receiver is governed by applicable statutory
requirements, and to the extent that such provision may not be in compliance
with such requirements.

Based upon the foregoing and subject to the qualifications stated herein, it is
our opinion that, when (i) the Registration Statement has been declared
effective under the Act, (ii) the Old Notes have been validly exchanged by the
Company, and (iii) the Notes have been executed and delivered by the Company
and authenticated by the Trustee, all in accordance with the terms of the
Indenture and the Registration Statement, the Notes will constitute valid and
binding obligations of the Company, enforceable against the Company in
accordance with their terms, and entitled to the benefits of the Indenture.

   
    


We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm contained therein under
the heading "Legal Matters."

                                        Very truly yours,

                                        /s/ HAYNES AND BOONE, L.L.P.

Board of Directors of the Company and to provide consideration for services
rendered by consultants and independent contractors for the Company and its
Affiliates, to encourage the sense of proprietorship of such persons and to
stimulate the active interest of such persons in the development and financial
success of the Company.  It is further intended that the options granted
pursuant to this Plan (the "Options") will be either incentive stock options or
nonqualified stock options.

         3.      ELIGIBILITY.  All employees of the Company and its Affiliates
and all Nonemployee Directors are eligible for Options under this Plan.  The
Committee shall select the Optionees in the Plan from time to time by the grant
of Options under the Plan.  The Committee may select, by the grant of options
under this Plan, certain consultants and independent contractors to be
Optionees.   The granting of Options under this Plan shall be entirely
discretionary and nothing in this Plan shall be deemed to give any employee,
consultant or independent contractor of the Company or its Affiliates or any
Nonemployee Director any right to participate in this Plan or to be granted an
Option.

         4.      OPTION AGREEMENT.

                 (a)      The Committee shall determine the type or types of
Options to be granted to each Optionee under this Plan.  Each Option granted
hereunder shall be embodied in an Option Agreement, which shall contain such
terms, conditions and limitations as shall be determined by the Committee in
its sole discretion and shall be signed by the Optionee and by the Chief
Executive Officer or any other authorized officer of the Company for and on
behalf of the Company.  An Option Agreement may include provisions for the
repurchase by the Company of Common Stock acquired pursuant to the Plan and the
repurchase of an Optionee's option rights under the Plan.  Options may be
granted in combination or in tandem with, in replacement of, or as alternatives
to grants or rights under this Plan or any other employee plan of the Company
or any of its Affiliates, including the plan of any acquired entity.  An Option
may provide for the granting or issuance of additional, replacement or
alternative Options upon the occurrence of specified events, including the
exercise of the original Option.

                 (b)      Notwithstanding anything herein to the contrary, no
Optionee may be granted Options during any three-year period exercisable for
more than 60,000 shares of Common Stock under this Plan, subject to adjustment
as provided in Section 14.

         5.      COMMON STOCK RESERVED FOR THE PLAN.  The maximum number of
shares of Common Stock issuable pursuant to the exercise of Options granted
under the Plan shall be 194,000 shares of Common Stock. The Board and the
appropriate officers of the Company shall from time to time take whatever
actions are necessary to execute, acknowledge, file and deliver any documents
required to be filed with or delivered to any governmental authority or any
stock exchange or transaction reporting system on which shares of Common Stock
are listed or quoted in order to make shares of Common Stock available for
issuance pursuant to this Plan.  Shares of Common Stock subject to Options that
(i) are forfeited or terminated, (ii) expire unexercised, (iii) are settled in
cash in lieu of Common Stock, or (iv) are exchanged for Common Stock owned by
the Optionee upon exercise of an Option, shall immediately become available for
the granting of Options.  The Committee may from time to time adopt and observe
such procedures concerning the counting of shares against the Plan maximum as
it may deem appropriate under Rule 16b-3.

          6.     ADMINISTRATION.  This Plan shall be administered by the
Committee, which shall have full and exclusive power to interpret this Plan and
to adopt such rules, regulations and guidelines for carrying out this Plan as
it may deem necessary or proper, all of which powers shall be exercised in the
best interests of the Company and in keeping with the objectives of this Plan.
The Committee may, in its discretion but subject to any necessary approvals of
any stock exchange or regulatory body having jurisdiction over the securities
of the Company, provide for the extension of the exercisability of an Option,
accelerate the





                                      -3-
<PAGE>   4
vesting or exercisability of an Option, eliminate or make less restrictive any
restrictions contained in an Option, waive any restriction or other provision
of this Plan or an Option or otherwise amend or modify an Option in any manner
that is either (a) not adverse to the Optionee holding such Option or (b)
consented to by such Optionee, including (in either case) an amendment or
modification that may result in an ISO's losing its status as an ISO.  The
Committee may correct any defect or supply any omission or reconcile any
inconsistency in this Plan or in any Option in the manner and to the extent the
Committee deems necessary or desirable to carry it into effect.  Any decision
of the Committee in the interpretation and administration of this Plan shall
lie within its sole and absolute discretion and shall be final, conclusive and
binding on all parties concerned.  No member of the Committee or officer of the
Company to whom it has delegated authority in accordance with the provisions of
Section 7 of this Plan shall be liable for anything done or omitted to be done
by him or her, by any member of the Committee or by any officer of the Company
in connection with the performance of any duties under this Plan, except for
his or her own willful misconduct or as expressly provided by statute.

          7.     DELEGATION OF AUTHORITY.  The Committee may delegate to the
Chief Executive Officer and to other senior officers of the Company its duties
under this Plan pursuant to such conditions or limitations as the Committee may
establish, except that the Committee may not delegate to any person the
authority to grant Options to, or take other action with respect to, Optionees
who are subject to Section 16 of the Exchange Act or who are "covered
employees," as that term is defined under Section 162(m) of the Code.

         8.      STOCK OPTIONS.  Only employees of the Company or an Affiliate
may receive grants of ISOs.  Employees, consultants,  independent contractors
and Nonemployee Directors may receive grants of Nonqualified Options.

                 (a)      INCENTIVE STOCK OPTIONS.  An ISO shall consist of a
right to purchase a specified number of shares of Common Stock at an exercise
price specified by the Committee in the Option Agreement or otherwise, which
shall not be less than the Fair Market Value of the Common Stock on the grant
date; provided, however, that the exercise price of an ISO may not be less than
110% of such Fair Market Value if the ISO is awarded to any person who, at the
time of grant, owns stock representing more than 10% of the combined voting
power of all classes of stock of the Company or any Affiliate.  Each ISO shall
expire not later than ten years after the grant date (or not later than five
years after the grant date if the ISO is awarded to any person who, at the time
of grant, owns stock representing more than 10% of the combined voting power of
all classes of stock of the Company or any Affiliate), with the expiration date
to be specified by the Committee in the Option Agreement.  Any ISO granted
must, in addition to being subject to applicable terms, conditions and
limitations established by the Committee, comply with Section 422 of the Code.
Pursuant to the ISO requirements of Code Section 422, notwithstanding anything
herein to the contrary, (a) no ISO can be granted under the Plan on or after
the tenth anniversary of the Effective Date of the Plan, and (b) no Optionee
may be granted an ISO to the extent that, upon the grant of the ISO, the
aggregate Fair Market Value (determined as of the date the Option is granted)
of the Common Stock with respect to which ISOs (including Options hereunder)
are exercisable for the first time by the Optionee during any calendar year
(under all plans of the Company and any Affiliate) would exceed $100,000.

                 (b)      NONQUALIFIED OPTIONS.  A Nonqualified Option shall
consist of a right to purchase a specified number of shares of Common Stock at
an exercise price specified by





                                      -4-
<PAGE>   5
the Committee in the Option Agreement or otherwise.  Each Option shall expire
not later than ten years after the grant date, with the expiration date to be
specified by the Committee in the Option Agreement.

         9.      EXERCISE OF OPTIONS.

                 (a)      Options granted to employees, consultants,
independent contractors and Nonemployee Directors shall be exercisable in
accordance with the terms of the applicable Option Agreement.

                 (b)      Except as otherwise provided in Section 13, an Option
may be exercised solely by the Optionee during his lifetime or after his death
by the person or persons entitled thereto under his will or the laws of descent
and distribution.

                 (c)      The purchase price of the shares as to which an
Option is exercised shall be paid in full at the time of the exercise.  Such
purchase price shall be payable (i) in cash, (ii) if permitted by the
Committee, by means of tendering Common Stock or surrendering all or part of
that or any other Option, valued at Fair Market Value on the date of exercise,
or (iii) any combination thereof.  The Committee may provide for procedures to
permit the exercise or purchase of Options by (a) loans from the Company or (b)
use of the proceeds to be received from the sale of Common Stock issuable
pursuant to an Option.  No holder of an Option shall be, or have any of the
rights or privileges of, a shareholder of the Company in respect of any shares
subject to any Option unless and until certificates evidencing such shares
shall have been issued by the Company to such holder.

         10.     SHAREHOLDERS' AGREEMENT.  As a condition to receiving shares
of Common Stock upon exercise of an Option, the Optionee must execute the
Shareholders' Agreement then in effect, if any, among the shareholders of the
Company.

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

         12.     TERMINATION OF EMPLOYMENT OR TERMINATION OF DIRECTOR STATUS.
Upon the termination of employment for any reason of an Optionee who is an
employee of the Company or any Affiliate, the termination of service for any
reason of an Optionee who is a consultant or independent contractor of the
Company or any Affiliates, or in the event any Optionee who is a Nonemployee
Director ceases to be a Director, any unexercised Options shall be treated as
provided in the specific Option Agreement evidencing the Option.  In the event
of such a termination, the Committee may, in its discretion, provide for the
extension of the exercisability of an Option for any period that is not beyond
the applicable expiration date thereof, accelerate the vesting or
exercisability of an Option, eliminate or make less restrictive any
restrictions contained in an Option, waive any restriction or other provision





                                      -5-
<PAGE>   6
of this Plan or an Option or otherwise amend or modify the Option in any manner
that is either (a) not adverse to such Optionee or (b) consented to by such
Optionee.

         13.     ASSIGNABILITY.  Except as otherwise provided herein or as
provided in the Option Agreement, no Option granted under this Plan shall be
assignable or otherwise transferable by the Optionee (or his or her authorized
legal representative) during the Optionee's lifetime and, after the death of
the Optionee, other than by will or the laws of descent and distribution or
pursuant to a qualified domestic relations order (as defined in Section
401(a)(13) of the Code or Section 206(d)(3) of the United States Employee
Retirement Income Security Act of 1974, as amended); and any attempted
assignment or transfer in violation of this Section 13(b) shall be null and
void.  Upon the Optionee's death, the personal representative or other person
entitled to succeed to the rights of the Optionee (the "Successor Optionee")
may exercise such rights.  A Successor Optionee must furnish proof satisfactory
to the Company of his or her right to exercise the Option under the Optionee's
will or under the applicable laws of descent and distribution.

                 Subject to approval by the Committee in its sole discretion,
all or a portion of the Nonqualified Options granted to an Optionee under the
Plan may be transferable by the Optionee to (i) the spouse, ex-spouse,
children, step-children or grandchildren of the Optionee ("Immediate Family
Members"), (ii) a trust or trusts for the exclusive benefit of such Immediate
Family Members ("Immediate Family Member Trusts"), (iii) a partnership or
partnerships, or limited liability company, in which such Immediate Family
Members or Immediate Family Member Trusts have at least 99% of the equity,
profit and loss interests ("Immediate Family Member Partnerships"), (iv) an
entity exempt from federal income tax pursuant to Section 501(c)(3) of the
Code, (v) a split interest trust or pooled income fund described in Section
2522(c)(2) of the Code, and/or (vi) upon approval by the Committee, any other
persons or entities, including an individual, corporation, partnership, limited
partnership, limited liability partnership, limited liability company,
professional corporation, trust, estate, custodian, trustee, executor,
administrator, nominee, charity or other entity in its own or a representative
capacity; provided that the Option Agreement pursuant to which such Options are
granted (or an amendment thereto) must expressly provide for transferability in
a manner consistent with this Section.  Subsequent transfers of transferred
Options shall be prohibited except by will or the laws of descent and
distribution or pursuant to a qualified domestic relations order (as described
above), unless such transfers are made to the original Optionee or a person to
whom the original Optionee could have made a transfer in the manner described
herein.  No transfer shall be effective unless and until written notice of such
transfer is provided to the Company, in the form and manner prescribed by the
Company.  Following transfer, any such Options shall continue to be subject to
the same terms and conditions as were applicable immediately prior to transfer,
and, except as otherwise provided herein, the term "Optionee" shall be deemed
to refer to the transferee.  The events of termination of service in Section 12
shall continue to be applied with respect to the original Optionee, following
which the Options shall be exercisable by the transferee only to the extent and
for the periods specified in Section 12 or the Option Agreement.  The Committee
and the Company shall have no obligation to inform any transferee of an Option
of any expiration, termination, lapse or acceleration of such Option.  The
designation by an Optionee of a beneficiary will not constitute a transfer of
the Option.

         14.     ADJUSTMENTS; CHANGE IN CONTROL.

                 (a)      The existence of outstanding Options shall not affect
in any manner the right or power of the Company or its shareholders to make or
authorize any or all adjustments, recapitalizations, reorganizations or other
changes in the share capital of the Company or its business or any merger or
consolidation of the Company, or any issue of bonds, debentures, preferred or
prior preference shares (whether or not such issue is prior to, on a parity
with or junior to the shares of Common Stock) or the dissolution or liquidation
of the Company, or any sale or transfer of all or any part of its assets or
business, or any other corporate act or proceeding of any kind, whether or not
of a character similar to that of the acts or proceedings enumerated above.

                 (b)      In the event of any subdivision or consolidation of
outstanding shares of Common Stock (including by way of stock split or reverse
split) or declaration of a dividend payable in shares of Common Stock or
capital reorganization or reclassification or other transaction involving an
increase or reduction in the number of outstanding shares of Common Stock, the
Committee shall adjust proportionally: (i) the number of shares of Common Stock
reserved under this Plan and covered by outstanding Options; (ii) the exercise
price of such Options; (iii) the number of shares to be subject to future
Options; (iv) the appropriate Fair Market Value and other price determinations
for such Options; and (v) the maximum number of shares that may be granted to
an Optionee under Section 4(b)..  In the event of any other recapitalization or
capital reorganization of the Company, consolidation or merger of the Company
with another corporation or entity or the adoption by the Company of a plan of
exchange affecting the shares of Common Stock or any distribution to holders of
shares of Common Stock of securities or property (other than normal cash
dividends or dividends payable in shares of Common Stock), the Committee shall
make such adjustments or other provisions to outstanding Options as it may deem
equitable, including adjustments to avoid fractional shares, to give proper
effect to such event; provided that such adjustments shall only be such as are
necessary to maintain the proportionate interest of the Optionees and preserve,
without exceeding, the value of the Options.

         In the event of a corporate merger, consolidation, acquisition of
property or stock, separation, reorganization or liquidation, the Committee
shall be authorized (i) to issue or assume stock options, regardless of whether
in a transaction to which Section 424(a) of the Code applies, by means of
substitution of new Options for previously issued Options or an assumption of
previously issued Options as a part of such adjustment; (ii) to make provision,
prior to the transaction, for the acceleration of the vesting and
exercisability of, or lapse of restrictions with respect to, Options and the
termination of Options that remain unexercised at the time of such transaction;
or (iii) to provide for the acceleration of the vesting and exercisability of
the Options and the cancellation thereof in exchange for such payment as shall
be mutually agreeable to the Optionee and the Committee.

                 (c)      If so provided in the Option Agreement, an Option
shall become fully exercisable upon a Change in Control (as hereinafter
defined) of the Company.  For purposes of this Plan, a "Change in Control"
shall be conclusively deemed to have occurred if (and only if) any of the
following events shall have occurred:

                          (i) prior to the closing of an initial public
offering (an "IPO") of shares of capital stock of the Company, (A) a complete
sale of the Company's assets or a complete





                                      -7-
<PAGE>   8
liquidation of the Company, or (B) any other event that the Committee
determines to be a Change in Control; and

                          (ii) subsequent to the closing of an IPO of the
Company, (A) there shall be consummated any merger or consolidation pursuant to
which shares of the Company's Common Stock would be converted into cash,
securities or other property, or any sale, lease, exchange or other disposition
(excluding disposition by way of mortgage, pledge or hypothecation), in one
transaction or a series of related transactions, of all or substantially all of
the assets of the Company (a "Business Combination"), in each case unless,
following such Business Combination, the holders of the outstanding Common
Stock immediately prior to such Business Combination beneficially own, directly
or indirectly, more than 51% of the outstanding common stock or equivalent
equity interests of the corporation or entity resulting from such Business
Combination (including, without limitation, a corporation which as a result of
such transaction owns the Company or all or substantially all of the Company's
assets either directly or through one or more subsidiaries) in substantially
the same proportions as their ownership, immediately prior to such Business
Combination, of the outstanding Common Stock, (B) the shareholders of the
Company approve any plan or proposal for the complete liquidation or
dissolution of the Company, (C) any "person" (as such term is defined in
Section 3(a)(9) or Section 13(d)(3) under the Exchange Act or any "group" (as
such term is used in Rule 13d-5 promulgated under the Exchange Act), other than
the Company, any successor of the Company or any Subsidiary or any employee
benefit plan of the Company or any Subsidiary (including such plan's trustee),
becomes a beneficial owner for purposes of Rule 13d-3 promulgated under the
Exchange Act, directly or indirectly, of securities of the Company representing
30% or more of the Company's then outstanding securities having the right to
vote in the election of directors, (D) during any period of two consecutive
years, individuals who, at the beginning of such period constituted the entire
Board, cease for any reason (other than death) to constitute a majority of the
directors, unless the election, or the nomination for election by the Company's
shareholders, of each new director was approved by a vote of at least a
majority of the directors then still in office who were directors at the
beginning of the period, or (E) there shall occur any other event which the
Committee determines to be a Change in Control.

         15.     RESTRICTIONS.  This Plan, and the granting and exercise of
Options hereunder, and the obligation of the Company to sell and deliver Common
Stock under such Options, shall be subject to all applicable foreign and United
States laws, rules and regulations, and to such approvals on the part of any
governmental agencies or stock exchanges or transaction reporting systems as
may be required.  No Common Stock or other form of payment shall be issued with
respect to any Option unless the Company shall be satisfied based on the advice
of its counsel that such issuance will be in compliance with applicable federal
and state securities laws and the requirements of any regulatory authority
having jurisdiction over the securities of the Company.  Unless the Options and
Common Stock covered by this Plan have been registered under the Securities Act
of 1933, as amended, each person exercising an Option under this Plan may be
required by the Company to give a representation in writing in form and
substance satisfactory to the Company to the effect that he is acquiring such
shares for his own account for investment and not with a view to, or for sale
in connection with, the distribution of such shares or any part thereof.  If
any provision of this Plan is found not to be in compliance with such rules,
such provision shall be null and void to the extent required to permit this
Plan to comply with such rules.  Certificates evidencing shares of Common Stock
delivered under this Plan may be subject to such stop transfer orders and other
restrictions as the Committee may deem advisable under the rules, regulations
and





                                      -8-
<PAGE>   9
other requirements of the Securities and Exchange Commission, any securities
exchange or transaction reporting system upon which the Common Stock is then
listed and any applicable federal, foreign and state securities law.  The
Committee may cause a legend or legends to be placed upon any such certificates
to make appropriate reference to such restrictions.

         16.     AMENDMENTS OR TERMINATION.  Subject to the limitations set
forth in this Section 16, the Board may at any time and from time to time,
without the consent of the Optionees, alter, amend, revise, suspend, or
terminate the Plan in whole or in part.  In the event of any such amendment to
the Plan, the holder of any Option outstanding under the Plan shall, upon
request of the Committee and as a condition to the exercisability thereof,
execute a conforming amendment in the form prescribed by the Committee to any
Option Agreement relating thereto within such reasonable time as the Committee
shall specify in such request.  Notwithstanding anything contained in this Plan
to the contrary, unless required by law, no action contemplated or permitted by
this Section 16 shall adversely affect any rights of Optionees or obligations
of the Company to Optionees with respect to any Options theretofore granted
under the Plan without the consent of the affected Optionee.

         Notwithstanding the foregoing, no amendment or modification shall be
made, without the approval of the shareholders of the Company:

                 (i)      Which would increase the total number of shares
         reserved for the purposes of the Plan under Section 5, except as
         provided in Section 14; or

                 (ii)     To the extent shareholder approval is otherwise
         required by applicable legal requirements or applicable stock exchange
         regulations.

Any amendment or modification to the Plan shall also be subject to any
necessary approvals of any stock exchange or regulatory body having
jurisdiction over the securities of the Company.

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

         18.     NO EMPLOYMENT GUARANTEED; NO ELECTION AS DIRECTOR GUARANTEED.
No provision of this Plan or any Option Agreement hereunder shall confer any
right upon any employee, consultant or independent contractor to continued
employment or service with the





                                      -9-
<PAGE>   10
Company or any Affiliate.  In addition, the granting of any Option shall not
impose upon the Company, the Board or any other Directors of the Company any
obligation to nominate any Nonemployee Director for election as a director and
the right of the shareholders of the Company to remove any person as a director
of the Company shall not be diminished or affected by reason of the fact that
an Option has been granted to such person.

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

         20.     EFFECTIVE DATE OF PLAN.  This Plan shall be effective as of
the Effective Date.  Notwithstanding the foregoing, the adoption of this Plan
is expressly conditioned upon the approval of the holders of a majority of
shares of Common Stock present, or represented, and entitled to vote at a
meeting of the Company's shareholders held on or before the date one year after
the Effective Date.  If the shareholders of the Company should fail so to
approve this Plan prior to such date, this Plan shall terminate and cease to be
of any further force or effect and all grants of Options hereunder shall be
null and void.

                 Attested to by the Secretary of Michael Holdings, Inc. as
         adopted by the Board of Directors of Michael Holdings, Inc. effective
         as of the 27th day of March, 1998 (the "Effective Date"),
         and approved by shareholders of Michael Holdings, Inc. on the 27th day
         of March, 1998.

                                   ARTICLE II
                                 THE COMMITMENT

         2.1      Maximum Amount of Facility. Subject to and in reliance upon
the terms, conditions, representations and warranties in the Loan Documents,
Lenders severally and not jointly agree to make to Borrower on one or more
Business Days prior to the Termination Date (subject to the limitation on the
number of Interest Periods that may exist at any time under SECTION 2.13)
secured loans on a reducing revolving basis (the "LOANS") in an amount up to an
aggregate principal amount outstanding at any one time of the lesser of such
Lender's Committed Amount or its Pro Rata Part of the Borrowing Base. Borrower
acknowledges that Lenders do not intend to advance Borrower any amount which
would at any point in time cause the aggregate principal amount of the Loans and
the undrawn amount of all LCs to exceed the Borrowing Base; provided, however,
that if obligations of Borrower under the Loans together with the undrawn amount
of all LCs exceed such amount, all such obligations shall nevertheless
constitute Obligations under this Agreement and shall be entitled to the benefit
of the Collateral. Prior to the Termination Date, any Principal Debt prepaid
may, subject to the conditions of this Agreement, be reborrowed hereunder, and
this Agreement shall not be deemed terminated or canceled solely because the
Obligations may from time to time be paid in full.

         2.2      Purpose of Advances. Proceeds of the Loans shall be used to
finance working capital needs of Borrower and for its general corporate purposes
in the ordinary course of business. Multiple Advances shall be permitted under
the Loans, provided that all conditions precedent thereto set forth in ARTICLE
VIII have been satisfied.

         2.3      Advance Procedure.

                  (a)    Each Advance shall be in an amount of not less than
         $500,000 or a greater integral multiple of $250,000 (unless the amount
         available for borrowing is less). With respect to Advances, Borrower
         must give Agent prior written notice in substantially the form of
         EXHIBIT C of the Advance to be made and specifying the date and amount
         thereof and whether such Advance is to be an ABR Advance or a
         Eurodollar Rate Advance and, if a Eurodollar Rate Advance, the Interest
         Period therefor pursuant to SECTION 2.13(a) (a "BORROWING REQUEST"). A
         Borrowing Request for an ABR Advance must be delivered to Agent by
         11:00 a.m. New York time on the day of the Advance. A Borrowing Request
         for a Eurodollar Rate Advance must be delivered to Agent by 1:00 p.m.
         New York time on the third Business Day prior to the day of the
         Advance. Each Borrowing Request shall be irrevocable and binding on
         Borrower.

                  (b)    On the Borrowing Date, each Lender shall remit its
         Commitment Percentage of each requested Advance to Agent's office in
         New York City, in funds that are available for immediate use by Agent
         by 12:00 noon on the applicable Borrowing Date. Subject to receipt of
         such funds, Agent shall (unless to its actual knowledge any of the
         applicable conditions precedent have not been satisfied by Borrower or
         waived by Required Lenders) make such funds available to Borrower by
         deposit into the operating account maintained by Borrower with Agent in
         New York City (or such other account as may be designated by Borrower
         in the Borrowing Notice and is acceptable to Agent); and absent
         contrary written notice from a Lender, Agent may assume that each
         Lender has made its Commitment Percentage of the requested Advance
         available to Agent on the applicable Borrowing Date, and Agent may, in
         reliance upon such assumption (but shall not be required to),




                                       14

<PAGE>   20



         make available to Borrower a corresponding amount. If a Lender fails to
         make its Commitment Percentage of any requested Advance available to
         Agent on the applicable Borrowing Date, Agent may recover the
         applicable amount on demand (i) from that Lender, together with
         interest at the Federal Funds Rate during the period commencing on the
         date the amount was made available to Borrower by Agent and ending on
         (but excluding) the date Agent recovers the amount from that Lender, or
         (ii) if that Lender fails to pay its amount upon demand, then from
         Borrower, together with interest at the rate applicable to the
         requested Advance during the period commencing on the Borrowing Date
         and ending on (but excluding) the date Agent recovers the amount from
         Borrower. No Lender is responsible for the failure of any other Lender
         to make its Commitment Percentage of any Advance.

         2.4      Notes. Borrower's obligation to repay the Loans shall be
evidenced by promissory notes executed by Borrower substantially in the form of
EXHIBIT A in favor of each Lender.

         2.5      Interest.

                  (a)    Interest. All interest shall be computed on the actual
         number of days elapsed over a year comprised of 360 days (or 365/366
         days, in the case of ABR Loans, the interest rate payable on which is
         then based on the Prime Rate) for actual days elapsed. In the case of
         ABR Loans, interest shall be due and payable in accordance with SECTION
         2.7 in immediately available funds quarterly in arrears and in full on
         the Termination Date. In the case of Eurodollar Loans, interest shall
         be due on the last day of each relevant Interest Period and, in the
         case of any Interest Period longer than three months, on each
         successive date three months after the first day of such Interest
         Period. Each change in the Eurodollar Rate shall take effect for new
         Eurodollar Rate Advances on the date of such Eurodollar Rate Advance
         and with respect to outstanding Eurodollar Rate Advances, on the first
         day of each new Interest Period therefor.

                  (b)    Interest Recapture. If at any time the interest rate
         designated by Borrower pursuant to SECTION 2.3 (the "DESIGNATED RATE")
         exceeds the Highest Lawful Rate, the rate of interest on such Advance
         shall be limited to the Highest Lawful Rate, but any subsequent
         reductions in the Designated Rate shall not reduce the rate of interest
         thereon below the Highest Lawful Rate until the total amount of
         interest accrued thereon equals the amount of interest which would have
         accrued thereon if the Designated Rate had at all times been in effect.
         In the event that at maturity (stated or by acceleration), or at final
         payment of any Note, the total amount of interest paid or accrued is
         less than the amount of interest which would have accrued if the
         Designated Rate had at all times been in effect, then, at such time and
         to the extent permitted by Law, Borrower shall pay an amount equal to
         the positive difference, if any, between (a) the lesser of the amount
         of interest which would have accrued if the Designated Rate had at all
         times been in effect and the amount of interest which would have
         accrued if the Highest Lawful Rate had at all times been in effect, and
         (b) the amount of interest actually paid or accrued on such Note.

         2.6      Repayment of Principal of and Interest.

                  (a)    On the Termination Date, Borrower shall pay to each
         Lender all outstanding principal and accrued and unpaid interest under
         the Loans.




                                       15

                  (b)    If no Default or Potential Default exists, any payment
         shall be applied to the Obligations in the order and manner directed by
         Borrower. If a Default or Potential Default exists, any payment
         (including proceeds from the exercise of any Rights) shall be applied
         in the following order: (i) to all fees and expenses for which Agent or
         Lenders have not been paid or reimbursed in accordance with the Loan
         Documents (and if such payment is less than all unpaid or unreimbursed
         fees and expenses, then the payment shall be paid against unpaid and
         unreimbursed fees and expenses in the order of incurrence or due date);
         (ii) to accrued interest on the Principal Debt; (iii) to the Principal
         Debt outstanding; (iv) to any LC reimbursement obligations that are due
         and payable and that remain unfunded; (v) to the remaining Obligations
         in the order and manner Required Lenders deem appropriate; and (vi) as
         a deposit with Agent, for the benefit of Lenders, as security for and
         payment of any subsequent LC reimbursement obligations.

         2.7      Time and Place of Payments. Each payment or prepayment on the
Obligations must be paid at Agent's principal office in New York, New York, in
funds which are or will be available for immediate use by Agent by 2:00 p.m.
(New York time) on the day due. If any action is required or any payment is to
be made on a day which is not a Business Day, then such action or payment may be
delayed until the next succeeding Business Day; provided that, with respect to a
Eurodollar Rate Advance, if the next succeeding Business Day is in the next
calendar month, such payment shall be taken or made on the next-preceding
Business Day. Any extension of time shall be included in the computation of
payments of interest and fees. Agent shall pay to each Lender any payment or
prepayment to which that Lender is entitled on the same day Agent receives the
funds from Borrower if Agent receives the payment or prepayment before 2:00 p.m.
and otherwise before 2:00 p.m. on the following Business Day. If and to the
extent that Agent does not make payments to Lenders when due, unpaid amounts
shall accrue interest at the Federal Funds Rate from the due date until (but not
including) the payment date.

         2.8      Optional Prepayment; Cancellation of Commitments.

                  (a)    Borrower may, without premium or penalty, and upon at
         least one Business Day's irrevocable written notice to Agent, prepay
         the Principal Debt from time to time and at any time, in whole or in
         part, without penalty, but subject to the provisions of SECTION
         2.18(b); provided that (i) each prepayment shall be in an amount of not
         less than $500,000 or a greater integral multiple of $250,000 in excess
         thereof, and (ii) all accrued interest on the amount prepaid shall be
         paid to the date of such prepayment. A notice of prepayment from
         Borrower shall constitute a binding obligation of Borrower to make a
         prepayment on the date stated therein. Amounts prepaid under this
         SECTION 2.8(a) may be reborrowed in accordance with this ARTICLE II.

                  (b)    Agent may, without premium or penalty to Borrower,
         apply to the Principal Debt insurance proceeds in excess of $500,000
         received by Agent pursuant to SECTION 6.9.

                  (c)    Borrower may, without premium or penalty, and upon at
         least three Business Days' prior irrevocable written notice to Agent,
         terminate all or part of the unused portion of the Total Commitment.
         Each partial termination must be in an amount of not less than $500,000
         or a greater integral multiple of $250,000, and shall be Pro Rata among
         all Lenders. Once terminated or reduced, the Total Commitment may not
         be increased or reinstated without the agreement of all parties hereto.

         2.9      Mandatory Prepayment. If the Principal Debt (together with LC
Exposure) ever exceeds the Borrowing Base or the Total Commitment (as either may
be reduced or canceled in accordance with this 



                                       16

<PAGE>   22



Agreement), Borrower shall, within 30 days, either repay such excess in full or
(in the case of a Borrowing Base Deficiency) provide additional collateral
acceptable to Required Lenders to increase the Borrowing Base in an amount
sufficient to eliminate such Borrowing Base Deficiency.

         2.10     LC Subfacility.

                  (a)    $6,000,000 LC Subfacility. Subject to the terms and
         conditions of this Agreement and applicable Law, a portion of the
         Facility not in excess of $6,000,000 shall be available to Borrower for
         the issuance of LCs by Agent, in the capacity of Issuing Lender, for
         Borrower's account upon Borrower's delivery of an LC Request in the
         form of EXHIBIT D, which must be received by Agent no later than 10:00
         a.m. on the second Business Day before the requested LC is to be
         issued; provided that the LC Exposure under this SECTION 2.10(a) may
         not exceed $6,000,000.

                  (b)    Expiration of LCs. No LC issued under this SECTION 
         2.10(a) shall have an expiration date after the earlier of (i) 18
         months after the date of issuance and (ii) five Business Days prior to
         the Termination Date; provided, however, that any such LC may provide
         for the automatic renewal thereof for additional periods of up to 18
         months each (which shall in no event extend beyond the date referred to
         in clause (ii) above).

                  (c)    To induce Agent to issue and maintain LCs, and to
         induce Lenders to participate in issued LCs, Borrower agrees to pay or
         reimburse Agent on or before the actual payment date with respect to
         any draft or draw under any LC, (i) the amount paid or to be paid by
         Agent and (ii) promptly, upon demand, any fees due under SECTION
         2.25(c) with respect to such LC. If Borrower does not timely pay or
         reimburse Agent for any drafts or draw requests paid or to be paid,
         Agent is irrevocably authorized to fund Borrower's reimbursement
         obligations as an ABR Advance and the proceeds of such ABR Advance
         shall be advanced directly to Agent to pay Borrower's unpaid
         reimbursement obligations. If funds cannot be advanced or if Agent
         elects not to exercise the authority granted it for the immediately
         preceding sentence to fund the reimbursement obligations as an ABR
         Advance, then Borrower's reimbursement obligation shall constitute a
         demand obligation bearing interest at the Default Rate from the date
         Agent pays the applicable draft or draw request through the date Agent
         is paid or reimbursed by Borrower. Borrower's obligations under this
         SECTION 2.10(c) are absolute and unconditional under any and all
         circumstances and irrespective of any setoff, counterclaim or defense
         to payment that Borrower may have at any time against Agent or any
         other Person, provided that Borrower shall have no liability or
         obligation for any reimbursement obligations arising in respect of
         draft or draw requests honored by Agent as a result of Agent's gross
         negligence or willful misconduct.

                  (d)    Immediately upon Agent's issuance of any LC, Agent
         shall be deemed to have sold and transferred to each Lender, and each
         other Lender shall be deemed irrevocably and unconditionally to have
         purchased and received from Agent, without recourse or warranty, an
         undivided interest and participation (to the extent of such Lender's
         Pro Rata Part) in the LC and all applicable rights of Agent in the LC
         (other than rights to receive certain fees payable solely to the
         Issuing Lender provided for in SECTION 2.25(c)). Agent agrees to
         provide a copy of each LC to each other Lender promptly upon request.
         However, Agent's failure to promptly send to Lenders a copy of an
         issued LC shall not affect the rights and obligations of Agent and
         Lenders under this Agreement.




                                       17

<PAGE>   23


                  (e)    All LCs shall count against the Borrowing Base and at
         no time may the total of (a) the Principal Debt and (b) the LC
         Exposure, exceed the Borrowing Base. Draws under any LC shall be
         reimbursed by Borrower (whether with its own funds or with the proceeds
         of the Loans) on the same Business Day.

                  (f)    Agent shall promptly notify Borrower of the date and
         amount of any draft or draw request presented for honor under any LC
         (but failure to give notice will not affect Borrower's obligations
         under this Agreement). Agent shall pay the requested amount upon
         presentment of a draft or draw request, unless presentment on its face
         does not comply with the terms of the applicable LC. When making
         payment, Agent may disregard (i) any default or potential default that
         exists under any agreement (other than the LC) and (ii) obligations
         under any agreement (other than the LC) that have or have not been
         performed by the beneficiary or any other Person (and Agent is not
         liable for any of those obligations). Borrower's reimbursement
         obligations to Agent and Lenders, and each Lender's obligations to
         Agent, are absolute and unconditional irrespective of, and Agent is not
         responsible for, (1) the validity, enforceability, sufficiency,
         accuracy or genuineness of documents or endorsements (even if they are
         in any respect invalid, unenforceable, insufficient, inaccurate,
         fraudulent or forged), (2) any dispute by any Company with, or any
         Company's claims, setoffs, defenses, counterclaims or other Rights
         against, Agent, any Lender or any other Person, or (iii) the occurrence
         of any Default, provided that Borrower shall have no liability or
         obligation for any reimbursement obligations arising in respect of
         draft or draw requests honored by Agent as a result of Agent's gross
         negligence or willful misconduct.

                  (g)    If Borrower fails to reimburse Agent as provided in
         this SECTION 2.10 and funds are not advanced to satisfy the
         reimbursement obligations, Agent shall promptly notify each Lender of
         Borrower's failure, of the date and amount paid, and of each Lender's
         Pro Rata Part of the unreimbursed amount. Each Lender shall promptly
         and unconditionally make available to Agent in immediately available
         funds its Pro Rata Part of the unpaid reimbursement obligation. Such
         funds are due and payable to Agent before the close of business on (i)
         the Business Day Agent gives notice to each Lender of Borrower's
         reimbursement failure if the notice is received by a Lender before
         12:00 noon in the time zone where such Lender's office listed on
         SCHEDULE 1 is located, or (ii) on the next succeeding Business Day
         after the Business Day Agent gives notice to each Lender of Borrower's
         reimbursement failure, if notice is received after 12:00 noon in the
         time zone where such Lender's office listed on SCHEDULE 1 is located.
         All amounts payable by any Lender accrue interest at the Federal Funds
         Rate from the day the applicable draft or draw is paid by Agent to (but
         not including) the date the amount is paid by Lender to Agent.

                  (h)    Borrower acknowledges that each LC is deemed issued
         upon delivery to the beneficiary or Borrower. If Borrower requests any
         LC be delivered to Borrower rather than the beneficiary, and Borrower
         subsequently cancels that LC, Borrower agrees to return it to Agent
         together with Borrower's written certification that it has never been
         delivered to the beneficiary. If any LC is delivered to the beneficiary
         under Borrower's instructions, Borrower's cancellation is ineffective
         without Agent's receipt of the LC and the beneficiary's written consent
         to the cancellation.

                  (i)    Agent agrees with each Lender that it will examine all
         documents with reasonable care to ascertain that they appear on their
         face to be in accordance with the terms and conditions of the LC. Each
         Lender and Borrower agree that, in paying any draft or draw under any
         LC, Agent has 




                                       18

<PAGE>   24



         no responsibility to obtain any document (other than any documents
         expressly required by the respective LC) or to ascertain or inquire as
         to any document's validity, enforceability, sufficiency, accuracy or
         genuineness or the authority of any Person delivering it. Neither Agent
         nor its Representatives will be liable to any Lender or any Company for
         any LC's use or for any beneficiary's acts or omissions. Any action,
         inaction, error, delay or omission taken or suffered by Agent or any of
         its Representatives in connection with any LC, applicable draws, drafts
         or documents, or the transmission, dispatch or delivery of any related
         message or advice, if in conformity with applicable Laws and in
         accordance with the standards of care specified in the UCP, is binding
         upon Borrower and Lenders. Agent is not liable to any Company or any
         Lender for any action taken or omitted by Agent or its Representative
         in connection with any LC in the absence of gross negligence or willful
         misconduct.

                  (j)    On the Termination Date, upon the cancellation of the
         Total Commitment under SECTION 2.8, during the continuance of a Default
         under SECTION 9.1(d) or 9.1(e), or upon any demand by Agent during the
         continuance of any other Default, Borrower shall provide to Agent, for
         the benefit of Lenders, cash collateral in an amount equal to the
         then-existing LC Exposure. Any cash collateral provided by Borrower to
         Agent in accordance with this SECTION 2.10(j) shall be deposited by
         Agent in an interest bearing cash collateral account maintained with
         Agent at the office of Agent and invested in obligations issued or
         guaranteed by the United States and, upon the surrender of any LC,
         Agent shall deliver the appropriate funds on deposit in such collateral
         account to Borrower together with interest accrued on such funds.

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

                  (l)    Although referenced in any LC, terms of any particular
         agreement or other obligation to the beneficiary are not incorporated
         into this Agreement in any manner. The fees and other amounts payable
         with respect to each LC are as provided in this Agreement and drafts
         and draws under each LC are part of the Obligations.

         2.11     Borrowing Base.

                  (a)    During the period from and after the Closing Date until
         the Borrowing Base is redetermined in accordance with this SECTION
         2.11, the amount of the Borrowing Base shall be $30,000,000. The
         Borrowing Base shall be reduced on the last day of each calendar
         quarter, commencing March 31, 1999, and thereafter through the
         Termination Date, by the amount (the "BB REDUCTION AMOUNT") set forth
         on SCHEDULE 2 (or any revised SCHEDULE 2 ever delivered by Agent under
         this SECTION 2.11(a)) corresponding with the last day of the applicable
         calendar quarter. In addition, the Borrowing Base and the BB Reduction
         Amounts shall be automatically reduced from




                                       19

<PAGE>   25



         time to time upon the disposition of any Collateral by the Borrowing
         Base value and the BB Reduction Amounts, if any, assigned to such
         Collateral by Agent. The Borrowing Base and the BB Reduction Amount
         shall be determined in accordance with SECTION 2.11(b) by Agent and
         approved by Required Lenders as described below. The Borrowing Base and
         the BB Reduction Amounts are subject to redetermination in accordance
         with SECTION 2.11(d). Upon any redetermination of the Borrowing Base
         and the BB Reduction Amounts, such redetermination shall remain in
         effect until the next successive date that the Borrowing Base and BB
         Reduction Amounts are again redetermined and become effective under
         SECTION 2.11(d) and Agent shall promptly advise Borrower and each
         Lender of the redetermined Borrowing Base and circulate a revised
         SCHEDULE 2 reflecting such redetermined BB Reduction Amounts. So long
         as any part of the Total Commitment is in effect and until all of the
         Loans outstanding hereunder are paid in full, this Agreement shall be
         governed by the then effective Borrowing Base.

                  (b)    Agent will within thirty days of receipt of the most
         recent Reserve Report delivered under SECTION 5.5, and such other data
         and supplemental information as may, from time to time, be reasonably
         requested by Agent, redetermine the Borrowing Base and BB Reduction
         Amounts based on such Reserve Report and propose such redetermined
         Borrowing Base and BB Reduction Amounts to Lenders. After receiving
         notice of the proposed Borrowing Base and BB Reduction Amounts, Lenders
         shall have 15 days to agree or disagree with such proposal. Each
         redetermination of the Borrowing Base and BB Reduction Amounts must be
         approved by Required Lenders. Failure of a Lender to object to a
         proposed redetermination within 15 days after notice thereof is given
         to such Lender by Agent shall be deemed an approval of such
         redetermination by such Lender. If the Required Lenders cannot agree on
         the amount of such redetermined Borrowing Base and/or BB Reduction
         Amount within such time, the greater of (i) the lowest redetermination
         by any Lender, and (ii) the current Borrowing Base and BB Reduction
         Amount shall be in effect until the Required Lenders can reach an
         agreement as to the amount of the redetermined Borrowing Base and BB
         Reduction Amount.

                  (c)    Agent may exclude any Property (other than Properties
         which have a present value (discounted at 10%) in the aggregate of not
         more than 10% of the total present value of all Properties), or any
         portion of production therefrom from the Borrowing Base, at any time,
         because the status of title to such Property is not reasonably
         satisfactory or because such Property is not subject to a first
         priority lien in favor of Agent as security for the Obligations or
         because of receipt of a notice of non-consent delivered pursuant to
         SECTION 6.20.

                  (d)    So long as any of the Total Commitment is in effect and
         until payment in full of all Loans hereunder, effective on or about the
         last day of each April and October, commencing on October 31, 1998
         ("SCHEDULED REDETERMINATION DATES"), Agent, with the approval of
         Required Lenders, shall redetermine the amount of the Borrowing Base
         and the BB Reduction Amount in accordance with SECTION 2.11(b). In
         addition, at any time (i) Borrower may request up to two
         redeterminations of the Borrowing Base and the BB Reduction Amount at
         any time during any consecutive twelve-month period (an "UNSCHEDULED
         REDETERMINATION"), and (ii) Required Lenders may initiate an
         Unscheduled Redetermination at any time; provided, however, that
         Required Lenders may initiate only two such Unscheduled
         Redeterminations during any consecutive twelve-month period, and (iii)
         any dispositions by Borrower of Collateral in any calendar year for
         aggregate consideration in excess of the lesser of $4,000,000 or 5% of
         Borrower's total proved reserve value 



                                       20

<PAGE>   26



         as determined by Agent shall permit the Required Lenders to initiate an
         Unscheduled Redetermination. Any Unscheduled Redetermination shall be
         in accordance with SECTION 2.11(b).

         2.12     Quotation of Rates. Any representative of Borrower may call
Agent on or before the date on which notice of a Designated Rate is to be
delivered by Borrower in order to receive an indication of the rates then in
effect, but such projection shall not be binding upon Agent or Lenders nor
affect the rate of interest which thereafter is actually in effect when the
election is made.

         2.13     Eurodollar Interest Periods; Rollovers; Conversions.

                  (a)    When Borrower gives a Borrowing Request under SECTION
         2.3(a) that includes a Eurodollar Rate Advance, Borrower shall specify
         the interest period (each an "INTEREST PERIOD") applicable thereto,
         which shall, at the option of Borrower, be a period of 1, 2, 3 or 6 (or
         if acceptable to Lenders, 9 or 12) month period; provided that (a) the
         initial Interest Period for a Eurodollar Rate Advance shall commence on
         the date of such Advance and each Interest Period occurring thereafter
         in respect of such Advance shall commence on the day on which the next
         preceding Interest Period applicable thereto expires, (b) if any
         Interest Period for a Eurodollar Rate Advance begins on a day for which
         there is no numerically corresponding Business Day in the calendar
         month at the end of such Interest Period, such Interest Period shall
         end on the last Business Day of such calendar month, (c) no Interest
         Period may be chosen for a Eurodollar Rate Advance which would extend
         beyond the Termination Date, and (d) no more than five Interest Periods
         for Eurodollar Rate Advances shall be in effect at one time. Agent
         shall promptly notify each Lender of its receipt of any such notice and
         its contents.

                  (b)    Upon the occurrence and during the continuance of a
         Default hereunder, the rate of interest applicable to the Loans shall
         be two percent (2%) over the interest rate otherwise applicable
         hereunder (the "DEFAULT RATE").

                  (c)    On any Business Day, Borrower may convert an ABR
         Advance to a Eurodollar Rate Advance if Borrower is in compliance with
         ARTICLE VIII. At the end of an Interest Period, Borrower may "rollover"
         a Eurodollar Rate Advance into another Eurodollar Rate Advance if
         Borrower is in compliance with SECTION 8.3 or convert a Eurodollar Rate
         Advance to an ABR Advance, in each case by giving written notice to
         Agent. Any such notice shall be irrevocable and binding on Borrower,
         shall be substantially in the form of EXHIBIT C, shall specify the Type
         of Advance and, in the case of a Eurodollar Rate Advance, the new
         Interest Period requested, and shall be delivered no later than 1:00
         p.m. New York time on the third Business Day preceding the conversion
         or rollover. Agent shall promptly notify each Lender of its receipt of
         any such notice and its contents. If, upon the expiration of any
         Interest Period applicable to a Eurodollar Rate Advance, Borrower has
         failed to give notice of a desired conversion or rollover, Borrower
         shall be deemed to have converted such Advance to an ABR Advance.

         2.14     Basis Inadequate for Determining Eurodollar Rate. If, on or
before any date on which a Eurodollar Rate is to be determined, Agent or any
Lender determines (and Required Lenders agree with that determination) that (a)
dollar deposits in the appropriate amount for the appropriate period are not
available in the London inter-bank market, or (b) the applicable Eurodollar Rate
does not accurately reflect the cost to Lenders of making or maintaining
Advances for such Interest Period, then Agent shall promptly give notice




                                       21

<PAGE>   27



of such determination to Borrower and Lenders and, until such condition no
longer exists, Lenders' commitment hereunder to make Eurodollar Rate Advances
shall be suspended.

         2.15     Additional Costs. With respect to any Law, requirement, 
request, directive or change affecting banking institutions generally:

                  (a)    With respect to any Eurodollar Rate Advance or ABR
         Advance, if (i) any change in present Law or any future Law imposes,
         modifies, or deems applicable (or if compliance by any Lender with any
         such requirement of any Tribunal results in) any such requirement that
         any reserves (including, without limitation, any marginal, emergency,
         supplemental or special reserves) be maintained, and (ii) those
         reserves reduce any sums receivable by that Lender under this Agreement
         or increase the costs incurred by that Lender in advancing or
         maintaining any portion of any Eurodollar Rate Advance, or ABR Advance,
         then (unless the effect is already reflected in the rate of interest
         then applicable under this Agreement) that Lender (through Agent) shall
         deliver to Borrower a certificate setting forth in reasonable detail
         the calculation of the amount necessary to compensate it for its
         reduction or increase (which certificate is conclusive and binding
         absent manifest error), and Borrower shall promptly pay that amount to
         that Lender upon demand, provided, however, that no Lender may claim
         any such compensation for any period of time prior to the date which is
         90 days prior to the date such notice is received by Borrower. The
         provisions of and undertakings and indemnification set forth in this
         paragraph shall survive the satisfaction and payment of the Obligation
         and termination of this Agreement.

                  (b)    With respect to any Advance or LC, if any change in
         present Law or any future Law regarding capital adequacy or compliance
         by Agent (as issuer of LCs) or any Lender with any request, directive
         or requirement now existing or hereafter imposed by any Tribunal
         regarding capital adequacy, or any change in its written policies or in
         the risk category of this transaction, reduces the rate of return on
         its capital as a consequence of its obligations under this Agreement to
         a level below that which it otherwise would have achieved (taking into
         consideration its policies with respect to capital adequacy) by an
         amount reasonably deemed by it to be material (and it may, in
         determining the amount, use reasonable assumptions and allocations of
         costs and expenses and use any reasonable averaging or attribution
         method), then (unless the effect is already reflected in the rate of
         interest then applicable under this Agreement) Agent or that Lender
         (through Agent) shall notify Borrower and deliver to Borrower a
         certificate setting forth in reasonable detail the calculation of the
         amount necessary to compensate it (which certificate is conclusive and
         binding absent manifest error), and Borrower shall promptly pay that
         amount to Agent or that Lender upon demand, provided, however, that no
         Lender may claim any such compensation for any period of time prior to
         the date which is 90 days prior to the date such notice is received by
         Borrower. The provisions of and undertakings and indemnification set
         forth in this paragraph shall survive the satisfaction and payment of
         the Obligations and termination of this Agreement.

                  (c)    Any Taxes payable by Agent or any Lender or ruled (by a
         Tribunal) payable by Agent or any Lender in respect of any Loan
         Document shall, if permitted by Law, be paid by Borrower, together with
         interest and penalties, if any (except for (i)(1) Taxes imposed on or
         measured by the overall net income of Agent or that Lender (2)
         franchise or similar taxes of the Agent or that Lender and (3) amounts
         requested to be withheld for Taxes pursuant to the last sentence of
         SECTION 2.24 and (ii) interest and penalties incurred as a result of
         the gross negligence or willful misconduct of Agent or any Lender).
         Agent or that Lender (through Agent) shall notify Borrower and deliver





                                       22

<PAGE>   28



         to Borrower a certificate setting forth in reasonable detail the
         calculation of the amount of payable Taxes, which certificate is
         conclusive and binding (absent manifest error), and Borrower shall
         promptly pay that amount to Agent for its account or the account of
         that Lender, as the case may be. If Agent or that Lender subsequently
         receives a refund of the Taxes paid to it by Borrower, then each
         recipient shall promptly pay the refund to Borrower.

         2.16     Illegality. If at any time any Law or any interpretation by a
Tribunal of competent jurisdiction of any Law shall make it unlawful for any
Lender to make or maintain Eurodollar Rate Advances, then such Lender (through
Agent) shall promptly notify Borrower, and Lenders shall not be obligated to
make any requested Eurodollar Rate Advance which would be unlawful with respect
to any Lender.

         2.17     Replacement Lender. In the event any Lender invokes SECTION
2.15 or SECTION 2.16, then, unless such Lender has removed or cured the
conditions actuating such Section, Borrower may designate a substitute lender
reasonably acceptable to Agent (such lender referred to in this Agreement as a
"REPLACEMENT LENDER") to purchase such Lender's rights and obligations with
respect to its entire Pro Rata Part under this Agreement. Any such purchase
shall be without recourse to or warranty by, or expense to, the Lender in
accordance with SECTION 11.3, and shall have a purchase price equal to the
outstanding principal amounts payable to the Lender with respect to its entire
Pro Rata Part under this Agreement, plus any accrued and unpaid interest, fees
and charges in respect of such Lender's Pro Rata Part, and on other terms
reasonably satisfactory to Agent. Upon such purchase by the Replacement Lender
and payment of all other amounts owing to the Lender being replaced, such
exiting Lender shall no longer be a party to this Agreement or have any rights
or obligations under this Agreement and the Replacement Lender shall succeed to
the Rights and obligations of the exiting Lender with respect to the exiting
Lender's Pro Rata Part and Commitments under this Agreement.

         2.18     Consequential Loss.

                  (a)    If, after Borrower requests a Eurodollar Rate Advance,
         the conditions precedent for such Advance are not satisfied (unless
         waived by Required Lenders), or if Borrower otherwise fails to take
         such Advance or any part thereof, Borrower shall pay to Lenders, upon
         demand, any actual costs or losses resulting therefrom (including,
         without limitation, those incurred by reason of the liquidation or
         re-employment of deposits or other funds acquired by Lenders to fund or
         maintain such Advance).

                  (b)    If any payment of principal is made upon a Eurodollar
         Rate Advance on a date other than the last day of the Interest Period
         therefor, Borrower shall pay to Lenders, upon demand, any actual costs
         or losses resulting therefrom (including, without limitation, those
         incurred by reason of the liquidation or re-employment of deposits or
         other funds acquired by Lenders to fund or maintain such Advance).

         2.19     Sharing of Payments, Etc. If any Lender obtains any payment
(whether voluntary, involuntary, or otherwise, including, without limitation, as
a result of exercising its Rights under SECTION 2.20) that exceeds its Pro Rata
Part, then that Lender shall purchase from the other Lenders participations that
will cause the purchasing Lender to share the excess payment ratably with each
other Lender. If all or any portion of any excess payment is subsequently
recovered from the purchasing Lender, then the purchase of such participations
shall be rescinded and the purchase price restored to the extent of the
recovery. Borrower agrees that any Lender purchasing a participation from
another Lender under this 




                                       23

<PAGE>   29



section may, to the fullest extent permitted by Law, exercise all of its Rights
of payment (including the Right of offset) with respect to that participation as
fully as if that Lender were the direct creditor of Borrower in the amount of
that participation.

         2.20     Offset. Upon the occurrence of a Default, each Lender and
Participant shall be entitled to exercise (for the benefit of all Lenders and
Participants in accordance with SECTION 2.19) the Rights of offset and/or
banker's Lien against each and every account and other property, or any interest
therein, which Borrower may now or hereafter have with such Lender or
Participant, or which is now or hereafter in the possession of such Lender or
Participant, to the extent of the full amount of the Obligations.

         2.21     Calculation of Eurodollar Rate. The provisions of this
Agreement relating to calculation of the Eurodollar Rate are included only for
the purpose of determining the rate of interest or other amounts to be paid
hereunder that are based upon such rate, it being understood that Lenders shall
be entitled to fund and maintain such funding of all or any part of an Advance
as they see fit. All such determinations hereunder, however, shall be made as if
Lenders had actually funded and maintained funding of each Advance through the
purchase in the market for offshore dollars of one or more eurodollar deposits
in an amount equal to the principal amount of such Advance and having a maturity
corresponding to the applicable Interest Period.

         2.22     Booking Loans. Notwithstanding any contrary provision in
SECTION 11.17, any Lender may make, carry, or transfer its part of any Advance
at, to, or for the account of any of its branch offices or the office of any of
its Affiliates. However, no Affiliate is entitled to receive any greater payment
under SECTION 2.15 than the transferor Lender would have been entitled to
receive with respect to those Advances.

         2.23     Highest Lawful Rate. Regardless of any provision contained in
any Loan Document or any document related thereto, it is the intent of the
parties to this Agreement that neither Agent nor any Lender contract for,
charge, take, reserve, receive or apply, as interest on all or any part of the
Obligation any amount in excess of the Highest Lawful Rate or receive any
unearned interest in violation of any applicable Law, and, if Lenders ever do
so, then any excess shall be treated as a partial repayment or prepayment of
principal and any remaining excess shall be refunded to Borrower. In determining
if the interest paid or payable exceeds the Highest Lawful Rate, Borrower and
Lenders shall, to the maximum extent permitted under applicable Law, (a) treat
all Advances as but a single extension of credit (and Lenders and Borrower agree
that is the case and that provision in this Agreement for multiple Advances is
for convenience only), (b) characterize any nonprincipal payment as an expense,
fee or premium rather than as interest, (c) exclude voluntary repayments or
prepayments and their effects, and (d) amortize, prorate, allocate and spread
the total amount of interest throughout the entire contemplated term of the
Obligations. However, if the Obligations are paid in full before the end of
their full contemplated term, and if the interest received for its actual period
of existence exceeds the Highest Lawful Rate, Lenders shall refund any excess
(and Lenders may not, to the extent permitted by Law, be subject to any
penalties provided by any Laws for contracting for, charging, taking, reserving
or receiving interest in excess of the Maximum Amount). If the Laws of the State
of Texas are applicable for purposes of determining the "Maximum Rate" or the
"Maximum Amount," then such terms refer to the "revised ceiling or bracket" from
time to time in effect under V.T.C.A., Finance Code ss. 1.001 et seq (West
1997). Borrower agrees that V.T.C.A., Finance Code Chapter 346 (which regulates
certain revolving credit loan accounts and revolving tri-party accounts), does
not apply to the Obligations, other than ss. 346.004.

         2.24     Foreign Lenders Each Lender that is organized under the Laws
of any jurisdiction other than the United States of America or any State thereof
(a) represents to Agent and Borrower that (i) no Taxes are




                                       24

<PAGE>   30



required to be withheld by Agent or Borrower with respect to any payments to be
made to it in respect of the Obligations and (ii) it has furnished to Agent and
Borrower two duly completed copies of U.S. Internal Revenue Service Form 4224,
Form 1001, Form W-8, or any other tax form acceptable to Agent (wherein it
claims entitlement to complete exemption from U.S. federal withholding tax on
all interest payments under the Loan Documents), and (b) covenants to (i)
provide Agent and Borrower a new tax form upon the expiration or obsolescence of
any previously delivered form according to Law, duly executed and completed by
it, and (ii) comply from time to time with all Laws with regard to the
withholding tax exemption. If any of the foregoing is not true or the applicable
forms are not provided, then Borrower and Agent (without duplication) may deduct
and withhold from interest payments under the Loan Documents United States
federal income tax at the full rate applicable under the Code (and still be in
compliance with the terms hereof).

         2.25     Fees.

                  (a)    Treatment of Fees. The fees described in this SECTION
         2.25 and in the Fee Letter (a) are not compensation for the use,

         day but excluding the last day) elapsed, but computed as if each
         calendar year consisted of 360 days, unless computation would result in
         an interest rate in excess of the Highest Lawful Rate in which event
         the computation is made on the basis of a year of 365 or 366 days, as
         the case may be. The fees described in this SECTION 2.25 are in all
         events subject to the provisions of SECTION 2.23 of this Agreement.

                  (b)    Commitment Fees. Borrower shall pay a commitment fee
         calculated at 3/8% per annum on the average daily unused portion of the
         lesser of the (i) Borrowing Base and (ii) the Total Commitment, payable

         on all outstanding LCs at a per annum rate equal to 1.375% on the face
         amount of each such LC. A fronting fee equal to 1/8 of 1% per annum on
         the face amount of each LC shall be payable quarterly in arrears to the
         Issuing Lender for its own account. In addition, customary
         administrative, issuance, amendment, payment and negotiation charges,
         as applicable, shall be payable to the Issuing Lender for its own
         account.

                  (d)    Borrower shall pay Agent, solely for its own account,
         the fees (other than the fees described in SECTION 2.25(b) and (c))
         described in the Fee Letter.

                                   ARTICLE III

         substitutions, betterments, additions and proceeds therefrom, all of
         the foregoing of which are subject only to Permitted Encumbrances of
         the type described in CLAUSES (c), (e), (f), (g), (h) and (i) of the
         definition thereof, and (iv) additional collateral furnished pursuant
         to SECTION 7.9(b) (collectively, the "COLLATERAL").

                  (b)    Without limiting the foregoing, each Company, upon
         request, will properly execute any and all documents reasonably
         necessary to perfect Agent's security interests in, and/or mortgage
         liens on, the Collateral. Each Company will, at its own expense, upon
         the request of Agent, cause such Uniform Commercial Code or similar
         searches with respect to such Company, to be conducted as Agent may
         reasonably request from time to time in order to evidence, perfect,
         maintain or continue perfection, or confirm the rights and remedies, of
         Agent in and to the Collateral granted hereby and to perfect such
         security interests in after-acquired property constituting the
         Properties and to continue the perfection of the security interests
         granted therein and file financing statements against such Company
         relating to the security interests securing any Obligations.

                  (c)    Upon the payment and performance in full of the
         Obligations (other than obligations arising under any Hedge, providing
         that the Companies have complied with SECTION 11.16), Agent shall
         deliver to each Company, at such Company's expense, releases and
         satisfactions of all financing statements and all other Security
         Documents with an acknowledgment that the same have been terminated to
         the extent that they secure any portion of the Obligations.

         3.2      Release of Collateral. Upon any sale, transfer or disposition
of Collateral which is expressly permitted under this Agreement (or as otherwise
authorized by Required Lenders), and upon five Business Days prior written
notice by Borrower, Agent shall execute, at Borrower's expense, such documents
as may be necessary to evidence the release, without recourse or warranty, of
all of Agent's liens upon such Collateral; provided that (a) Agent shall not be
required to execute any such document on terms which, in Agent's opinion, would
expose it to liability, and (b) such release shall not in any manner discharge,
affect or impair the Obligations or the remaining Collateral.

         3.3      Additional Security and Guaranties. Agent or Lenders may,
without notice and without affecting Borrower's obligations under the Loan
Documents, from time to time take any additional security or guaranty for the
Obligations from any Person and subsequently exchange, enforce or release such
security or any part thereof.


                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

         In order to induce Lenders to make Loans, Borrower makes the following
representations and warranties to Agent and Lenders as of the Closing Date, each
and all of which shall survive the execution and delivery of this Agreement and

knowledge, all written data, reports and information which Borrower has supplied
to Agent or caused to be supplied by a third party on its behalf are complete

         6.3      Compliance with Tax Laws; Royalty Payments. Each Company shall
comply with all Federal, State or local laws and regulations regarding the
collection, payment and deposit of employees' income, unemployment and Social
Security taxes and will make all royalty or overriding royalty payments and
payments to all other interest owners in the Properties which it operates (other
than those payments held in suspense in the ordinary course of business in
accordance with oil and gas industry custom and practice).

         6.4      Books and Records. Each Company shall keep adequate records
and books of account with respect to its business activities, and with respect
to the Properties which it operates in accordance with the provisions of the
applicable Operating Agreement, in which proper entries are made in accordance
with GAAP reflecting all financial transactions of each Company.

         6.5      Litigation. Borrower shall give Agent prompt written notice of
any suit at law or in equity against any Company or any investigation or
proceeding before or by any administrative or governmental agency and known to
any Company which, if adversely determined, would result in a Material Adverse
Event.

         6.6      Compliance with Environmental Laws. Each Company shall duly
observe and comply in all material respects with all laws, rules and regulations
made by any governmental authority, and all valid requirements of any regulatory
body which may acquire jurisdiction, which apply or relate to any or all of the
Properties, including, without limitation, Environmental and Safety Regulations
and keep any or all of the Properties free and clear of any Encumbrances (other
than Permitted Encumbrances) imposed pursuant thereto .

         6.7      CERCLA. Each Company shall operate any Property (whether or
not such property constitutes a "facility" as defined by CERCLA) so that no
material cleanup or other obligation arises in respect of CERCLA or other
applicable Federal law or under any state, local or municipal law, statute
(including, without limitation, Hazardous Substance Laws), ordinance, rule or
regulation designed to protect the environment or relating to the disposition,
generation or transportation of hazardous waste, which would constitute a lien
or charge on any property of any Company prior to that of Agent or Lenders. If
any such claim be made or any obligation should nevertheless arise hereafter,
the Companies will, at their own expense, (a) promptly cure or cause a third
party to immediately cure the same and (b) indemnify and hold harmless Agent and
Lenders and their officers, directors, agents and employees from any liability,
responsibility or obligation in respect thereof or in respect of any cleanup or
other liability as successor, secured party or otherwise (regardless of whether
or not Lender may be deemed to be an "owner or operator" under CERCLA) for any
reason including, without limitation, the enforcement of Agent's and Lenders'
rights as secured parties under this Agreement, the Security Documents or by
operation of law.

         6.8      Notice of Release. In the event that any Company receives any
notice from any Person with regard to the Release of Hazardous Materials on, or
from, any or all of the Properties, Borrower shall give prompt written notice
thereof to Agent (and, in any event, prior to the expiration of any period in
which to respond to such notice under any applicable Environmental and Safety
Regulation).

         6.9      Maintenance of Property; Insurance. Each Company shall, at its
sole cost and expense, keep and maintain in respect of its properties and
business such insurance as is generally kept and maintained by reasonable and
prudent operators of oil and gas properties, including, but not limited to,
where applicable, blow-out insurance, workman's compensation insurance, property
insurance, and general liability insurance. All such policies of insurance shall
be in a form, in such amounts, with such deductibles, and with such insurers as
may be customary for oil and gas companies of similar size and operations for
each Company and




                                       33

<PAGE>   39


in accordance with industry practice. Policies of insurance and the certificates
evidencing the same shall contain an endorsement, in form and substance
acceptable to Agent, showing Agent as additional loss payee. Such endorsement or
an independent instrument furnished to Agent shall provide that the insurance
companies will give Agent at least 30 days prior notice before any such
insurance shall be altered or canceled. If no Default exists, the proceeds of
any such insurance shall be used to repair or replace the property the damage or
destruction of which gave rise to such insurance proceeds; provided that any
insurance proceeds in excess of $500,000 which are not used for repair or
replacement in accordance herewith, unless paid as reimbursement of expenses
incurred and business losses suffered in connection with the loss or damage, may
be retained by Agent and Lenders as a prepayment of the Obligation and applied
thereto in accordance with SECTION 2.8(b).

         6.10     Insurance Renewal or Replacement. Each Company shall obtain
prior to the expiration date of each policy maintained pursuant to SECTION 6.9,
a renewal or replacement thereof and Borrower shall deliver to Agent a
certificate of such renewal or replacement policy.

         6.11     Consultants. Each Company shall accord to Agent the right, to
be exercised reasonably to evaluate individual situations, with prior written
notice to Borrower (except upon the occurrence of an Event of Default in which
case no prior written notice is required), from time to time to select and
retain consultants, including, without limitation, the Engineers, to advise
Agent as to technical matters pertaining to the Companies' operations relating
to the Properties. Except as provided to the contrary herein, the reasonable
fees and costs charged by such consultants shall be paid by Borrower. Each
Company shall allow such consultants access during normal business hours to the
Properties and all other Company facilities relating to the Properties operated
by any Company (and will use reasonable efforts to obtain such access from the
operator of any Properties not operated by any Company) or the conduct of any
Company's business and to any Company's financial records relating to operation
of the Properties and all of its records of operations related thereto. Such
access shall not unreasonably disrupt the business of any Company or the
operations of the Properties.

         6.12     Inspections. Each Company shall so long as any Obligation
remains unfulfilled or any Collateral remains located at any of the Properties
or other facilities owned or leased by any Company, accord Agent, Lenders or
their agents full and unrestricted access upon the giving of reasonable prior
notice under the circumstances (subject to reasonable safety restrictions,
applicable confidentiality agreements and in accordance with prudent operator
standards) during normal business hours to the Properties and such other
facilities, including pipelines, operated by any Company and shall use
reasonable efforts to cause the operator of any non-operated Properties or other
facilities to provide such access, so as to permit Agent, Lenders or their
agents to, among other things, witness workovers and other field activities,
inspect or take delivery of production. Such access shall not unreasonably
disrupt the business of any Company or the operation of the Properties.

         6.13     Access to Companies. Each Company shall allow Agent and
Lenders, or their agents, access to appropriate officers, employees and agents
of each Company to discuss the affairs, finances and accounts of such Company
during regular business hours and upon reasonable notice and as often as they
may reasonably request.

account with Agent's New York Branch.

         6.15     Expenses.  Borrower shall pay the following:

<PAGE>   40




                  (a)    All reasonable out-of-pocket expenses of Agent
         associated with the syndication of the Facility and the preparation,
         execution, delivery, filing, recordation and administration of the Loan
         Documents and any amendment or waiver with respect thereto (including
         the reasonable fees, disbursements and other charges of counsel);

                  (b)    All out-of-pocket expenses of Agent and Lenders 
         (including the fees, disbursements and other charges of counsel) in
         connection with enforcement of the Loan Documents; and

                  (c)    All reasonable out-of-pocket engineering expenses
         associated with Agent's periodic review of the Borrowing Base and any
         reserves submitted by Borrower to Agent to be included in the Borrowing
         Base, not to exceed the amounts set forth in the Fee Letter and related
         Term Sheet.

         6.16     Taxes. Each Company shall promptly pay when due any and all
Taxes and other obligations, other than Taxes or obligations which are being
contested in good faith by lawful proceedings diligently conducted, against
which reserve or other provision required by GAAP has been made, and in respect
of which levy and execution of any Lien have been and continue to be stayed.

         6.17     Hydrocarbon Sales Contracts; Gas Balancing; Hedging. With
respect to the Interests included in the Borrowing Base, from and after the
Closing Date, the Companies will not enter into Hydrocarbon Hedges for amounts
exceeding 85% of the proved developed producing reserves as reflected in
Borrower's then most current Reserve Report without the prior written consent of
Agent. With respect to Interests operated by the Companies, the Companies shall
not become obligated with respect to gas balancing agreements or a take or pay
provision in a gas sales or purchase agreement under which it is required to
deliver volumes of gas without receiving full payment therefor which,
individually or in the aggregate, could result in a liability exceeding
$500,000. With respect to Interests operated by a Person other than the
Companies, the Companies shall promptly notify Agent of any such agreement or
provision of which they have knowledge which could reasonably be expected to
result in a Material Adverse Event.

         6.18     Further Assurances. Each Company shall perform such acts and
duly authorize, execute, acknowledge, deliver, file and record such additional
assignments, security agreements, deeds of trust, mortgages, financing
statements and other agreements, documents, instruments and certificates as
Agent may reasonably deem necessary or appropriate in order to perfect and
maintain the Agent's liens on the Collateral and preserve and protect the Rights
of Agent and Lenders under the Loan Documents.

         6.19     Indemnification. THE COMPANIES WILL INDEMNIFY, PROTECT AND
HOLD AGENT AND LENDERS AND THEIR RESPECTIVE PARENTS, SUBSIDIARIES,
REPRESENTATIVES, SUCCESSORS AND ASSIGNS (INCLUDING ALL OFFICERS, DIRECTORS,
EMPLOYEES AND AGENTS THEREOF)(COLLECTIVELY, THE "INDEMNIFIED PARTIES") HARMLESS
FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, CLAIMS AND PROCEEDINGS AND ALL COSTS,
EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL ATTORNEYS' FEES AND LEGAL EXPENSES
WHETHER OR NOT SUIT IS BROUGHT) AND DISBURSEMENTS OF ANY KIND OR NATURE (THE
"INDEMNIFIED LIABILITIES") THAT MAY AT ANY TIME BE IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST THE INDEMNIFIED PARTIES, IN ANY WAY RELATING TO OR ARISING OUT
OF (A) THE VIOLATION BY ANY COMPANY OF ANY ENVIRONMENTAL AND SAFETY LAW, (B) ANY
COMPANY'S GENERATION, MANUFACTURE, PRODUCTION, STORAGE, RELEASE, THREATENED
RELEASE, DISCHARGE, DISPOSAL OR PRESENCE IN CONNECTION WITH ITS PROPERTIES OF A
HAZARDOUS SUBSTANCE (INCLUDING, WITHOUT LIMITATION, (I) ALL DAMAGES OF ANY USE,

OR OTHER PLANS), OR (C) THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS
CONTEMPLATED THEREIN (OTHER THAN THOSE ARISING FROM ANY ACTION OR LACK OF ACTION
BY THE INDEMNIFIED PARTIES). HOWEVER, ALTHOUGH EACH INDEMNIFIED PARTY HAS THE
RIGHT TO BE INDEMNIFIED HEREUNDER UNDER CERTAIN CIRCUMSTANCES FOR ITS OWN
ORDINARY NEGLIGENCE, NO INDEMNIFIED PARTY HAS THE RIGHT TO BE INDEMNIFIED
HEREUNDER FOR ITS OWN FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. THE
PROVISIONS OF AND UNDERTAKINGS AND INDEMNIFICATION SET FORTH IN THIS PARAGRAPH
SHALL SURVIVE THE SATISFACTION AND PAYMENT OF THE OBLIGATION AND TERMINATION OF
THIS AGREEMENT.

         6.20     Notice of Non-Consent. Borrower shall promptly provide Agent
with telephonic notice, which shall be confirmed by written notice within five
Business Days thereof, if any Company has become a non-consenting party with
respect to any Operating Agreement.


                                   ARTICLE VII
                               NEGATIVE COVENANTS

Security Documents and other documents and instruments executed in connection
with the Security Documents; provided, however, that the foregoing shall not
prohibit the endorsement of negotiable instruments for deposit or collection or
incurrence of obligations under the Operating Agreements and similar
transactions in the ordinary course of business. For the purposes hereof
"guaranty" shall include any agreement, whether such agreement is on a
contingency basis or otherwise, to purchase, repurchase or otherwise acquire any
obligation or liability of any other Person, or to purchase, sell or lease, as
lessee or lessor, property or services, in any such case primarily for the
purpose of enabling another Person to make payment of any such debt or
liability, or to make any payment (whether as a capital contribution, purchase
of an equity interest or otherwise) to assure a minimum equity, asset base,
working capital or other balance sheet or financial condition, in connection
with debt or liability of another Person, or to supply funds to or in any manner
invest in another Person in connection with such Person's debt or liability.

                REMEDIES OF LENDERS AND AGREEMENTS AMONG LENDERS

         10.1     Remedies Upon Default.

                  (a)    Upon the occurrence of any Default other than under
         SECTIONS 9.1(d) and (e), Lenders may, following two Business Days'
         prior written notice, terminate this Agreement or may demand payment of
         all Obligations (whether otherwise then payable on demand or not)
         without terminating this Agreement and shall, in any event, be under no
         further responsibility to extend any credit or afford any financial
         accommodation to Borrower, whether under this Agreement or otherwise.
         Upon the occurrence of a Default under SECTIONS 9.1(d) or (e), Lenders
         may, without prior notice or demand to Borrower, terminate this
         Agreement or demand payment of all Obligations (whether otherwise then
         payable on demand or not) without terminating this Agreement and shall,
         in any event, be under no further responsibility to extend any credit
         or afford any financial accommodation to Borrower, whether under this
         Agreement or otherwise. Upon a termination of this Agreement by Lenders
         following a Default, Agent and Lenders shall have, in addition to all
         of their other rights under this Agreement, any Security Document
         (including, without limitation, the assignment of production contained
         in the Mortgage, by operation of law or otherwise (which rights shall
         be cumulative), all of the rights and remedies of a secured party under
         the Uniform Commercial Code and shall have the right to enter upon any
         premises where the Collateral is kept and peacefully retake possession
         thereof.

                  (b)    Agent and Lenders shall not have any obligation to
         preserve rights to any Collateral against prior parties or to proceed
         first against any Collateral or to marshal any Collateral of any kind
         for the benefit of any other creditor of any Company or any other
         Person. After the occurrence and during the continuance of a Default,
         Agent and Lenders are hereby granted a license or other right to use,
         without charge, any Company's labels, patents, copyrights, rights of
         use of any name, trade secrets, trade names, trademarks and advertising
         matter, or any property of a similar nature, as it pertains to the
         Collateral, in completing production of, advertising for sale, and
         selling any Collateral and any Company's rights under all licenses and
         any franchise, sales or distribution agreements shall inure to Lenders'
         benefit.

                  (c)    Upon the occurrence of a Default, Lenders shall have
         the right to set-off and apply against the Obligations in such manner
         as Lenders may determine, at any time to any Company, any and all
         deposits (general or special, time or demand, provisional or final) or
         other sums at any time credited by or owing from Lenders or any
         depositary to any Company whether or not the Obligations are then due,
         except for any amounts owing to third-party Working Interest and
         Royalty Interest holders of which Lenders shall have been notified.
         Lenders shall provide notice to Borrower not later than five Business
         Days following any application of such funds. As further security for
         the Obligations, Borrower hereby grants to each Lender a security
         interest in all money, instruments, and other property of Borrower now
         or hereafter held by such Lender, including, without limitation,
         property held in safekeeping. In addition to each Lender's right of
         set-off and as further security for the Obligations, Borrower hereby
         grants to each Lenders a security interest and lien in all deposits
         (general or special, time or demand, provisional or final) and other
         accounts of Borrower now or hereafter on deposit with or held by such
         Lender or any depositary and all other sums at any time credited by or
         owing from such Lender or any depositary to Borrower. The rights and
         remedies of Lenders hereunder are in addition to other rights and
         remedies (including, without limitation, other rights of set-off) which
         Lenders may have.





                                       43

<PAGE>   49




                  (d)    Upon the occurrence of a Default, Lenders shall have
         the right to exercise any Company's rights under the Operating
         Agreements subject to the liens and security interests of the Security
         Documents, including any right to remove and replace the Operator.

                  (e)    At any time during which a Default exists and is
         continuing, each Company authorizes Agent (a) to execute alone any
         financing statement or other documents or instruments that Agent may
         require to perfect, protect or establish any lien or security interest
         hereunder or under any Security Documents and further authorizes Agent
         to sign such Company's name on the same; and (b) to appoint such Person
         or Persons as Agent may designate as its agent and attorney-in-fact to
         endorse the name of such Company on any checks, notes, drafts or other
         forms of payment or security that may come into the possession of Agent
         or any Lender or any Affiliate of Agent or Lenders, to sign such
         Company's name on invoices or bills of lading, drafts against
         customers, notices of assignment, verifications and schedules and,
         generally, to do all things necessary to carry out this Agreement and
         the Security Documents. The powers granted herein, being coupled with
         an interest, are irrevocable. Neither Agent, Lenders nor their agents
         and attorneys-in-fact shall be liable for any act or omission, error in
         judgment or mistake of law so long as the same is not malicious,
         grossly negligent or evidences reckless misconduct. Upon payment and
         performance of all Obligations of the Companies to Agent and Lenders,
         such power of attorney will become null and void.

         10.2     Company Waivers. To the extent permitted by Law, each Company
waives presentment and demand for payment, protest, notice of intention to
accelerate, notice of acceleration and notice of protest and nonpayment, and
agrees that its liability with respect to all or any part of the Obligations is
not affected by any renewal or extension in the time of payment of all or any
part of the Obligations, by any indulgence, or by any release or change in any
security for the payment of all or any part of the Obligations.

         10.3     Performance by Agent. If any covenant, duty or agreement of
any Company is not performed in accordance with the terms of the Loan Documents,
Agent may, while a Default exists, at its option (but subject to the approval of
Required Lenders), perform or attempt to perform that covenant, duty or
agreement on behalf of that Company (and any amount expended by Agent in its
performance or attempted performance is payable by the Companies to Agent on
demand, becomes part of the Obligations, and bears interest at the Default Rate
from the date of Agent's demand therefor until paid). However, neither Agent nor
any Lender assumes or shall have, except by its express written consent, any
liability or responsibility for the performance of any covenant, duty or
agreement of any Company.

         10.4     Not in Control. None of the covenants or other provisions
contained in any Loan Document shall, or shall be deemed to, give Agent or
Lenders the Right to exercise control over the assets (including, without
limitation, real property), affairs, or management of any Company; the power of
Agent and Lenders is limited to the Right to exercise the remedies provided in
this ARTICLE X.

         10.5     Course of Dealing. The acceptance by Agent or Lenders of any
partial payment on the Obligations shall not be deemed to be a waiver of any
Default then existing. No waiver by Agent, Required Lenders or Lenders of any
Default shall be deemed to be a waiver of any other then-existing or subsequent
Default. No delay or omission by Agent, Required Lenders or Lenders in
exercising any Right under the Loan Documents will impair that Right or be
construed as a waiver thereof or any acquiescence therein, nor will any single
or partial exercise of any Right preclude other or further exercise thereof or
the exercise of any other Right under the Loan Documents or otherwise.

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

         10.7     Agreements Among Lenders.

                  (a)    Agent

                         (i)       Each Lender appoints Agent (and Agent accepts
                  appointment) as its nominee and agent, in its name and on its
                  behalf: (i) to act as its nominee and on its behalf in and
                  under all Loan Documents with such powers as are expressly
                  delegated to Agent under the Loan Documents, together with
                  such other powers as are reasonably incidental thereto; (ii)
                  to arrange the means whereby its funds are to be made
                  available to Borrower under the Loan Documents; (iii) to take
                  any action that it properly requests under the Loan Documents
                  (subject to the concurrence of other Lenders as may be
                  required under the Loan Documents); (iv) to receive all
                  documents and items to be furnished to it under the Loan
                  Documents; (v) to be the secured party, mortgagee,

                  distribute to it all material information, requests, documents
                  and items received from the Companies under the Loan
                  Documents; (vii) to promptly distribute to it its ratable part
                  of each payment or prepayment (whether voluntary, as proceeds
                  of collateral upon or after foreclosure, as proceeds of
                  insurance thereon, or otherwise) in accordance with the terms
                  of the Loan Documents; and (viii) to deliver to the
                  appropriate Persons requests, demands, approvals and consents
                  received from it. However, Agent may not be required to take
                  any action that exposes it to personal liability or that is
                  contrary to any Loan Document or applicable Law.

                           (ii)         If the initial or any successor Agent
                  ever ceases to be a party to this Agreement or if the initial
                  or any successor Agent ever resigns (whether voluntarily or at
                  the request of Required Lenders), then Required Lenders shall
                  appoint the successor Agent from among Lenders (other than the
                  resigning Agent). If Required Lenders fail to appoint a
                  successor Agent within 30 days after the resigning Agent has
                  given notice of resignation or Required Lenders have removed
                  the resigning Agent, then the resigning Agent may, on behalf
                  of Lenders, appoint a successor Agent, which must be a Lender,
                  or in the event no Lender agrees to accept such appointment, a
                  commercial bank having a combined capital and surplus of at
                  least $1,000,000,000 (as shown on its most recently published
                  statement of condition). Upon its acceptance of appointment as
                  successor Agent, the successor Agent succeeds to and becomes
                  vested with all of the Rights of the prior Agent, and the
                  prior Agent is discharged from its duties and obligations of
                  Agent under the Loan Documents (but, when used in connection
                  with LCs issued and outstanding before the appointment of the
                  successor Agent, "Agent" shall continue to refer solely to
                  Christiania, but, any LCs issued or renewed after the
                  appointment of any successor Agent shall be issued or renewed
                  by the successor Agent), and the resigning or removed Agent
                  and each Lender shall execute such documents as any Lender,
                  the resigning or removed Agent, or the successor Agent
                  reasonably request to reflect the change. After any Agent's
                  resignation or removal as Agent under the Loan Documents, the

                  provisions of this ARTICLE X inure to its benefit as to any
                  actions taken or omitted to be taken by it while it was Agent
                  under the Loan Documents.

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

                           (iv)         Agent may now or hereafter be engaged in
                  one or more loan, letter of credit, leasing or other financing
                  transactions with any Company, act as trustee or depositary
                  for any Company or otherwise be engaged in other transactions
                  with any Company (collectively, the "OTHER ACTIVITIES") not
                  the subject of the Loan Documents. Without limiting the Rights
                  of Lenders specifically set forth in the Loan Documents, Agent
                  is not responsible to account to Lenders for those other
                  activities, and no Lender shall have any interest in any other
                  activities, any present or future guaranties by or for the
                  account of any Company that are not contemplated or included
                  in the Loan Documents, any present or future offset exercised
                  by Agent in respect of those other activities, any present or
                  future property taken as security for any of those other
                  activities, or any property now or hereafter in Agent's
                  possession or control that may be or become security for the
                  obligations of the Companies arising under the Loan Documents
                  by reason of the general description of indebtedness secured
                  or of property contained in any other agreements, documents,
                  or instruments related to any of those other activities (but,
                  if any payments in respect of those guaranties or that
                  property or the proceeds thereof is applied by Agent to reduce
                  the Obligations, then each Lender is entitled to share ratably
                  in the application as provided in the Loan Documents).

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

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

                  (d)    Delegation of Duties; Reliance. Lenders may perform any
         of their duties or exercise any of their Rights under the Loan
         Documents by or through Agent, and Lenders and Agent may perform any of
         their duties or exercise any of their Rights under the Loan Documents
         by or through their respective Representatives. Agent, Lenders and
         their respective Representatives (a) are entitled to rely upon (and
         shall be protected in relying upon) any written or oral statement
         believed by it or them to be genuine and correct and to have been
         signed or made by the proper Person and, with respect to legal matters,
         upon opinion of counsel selected by Agent or that Lender (but nothing
         in this SECTION 10.7(d) permits Agent to rely on (i) oral statements if
         a writing is required by this Agreement or (ii) any other writing if a
         specific writing is required by this Agreement), (b) are entitled to
         deem and treat each Lender as the owner and holder of its Pro Rata Part
         of the Principal Debt for all purposes until, subject to SECTION 11.2,
         written notice of the assignment or transfer is given to and received
         by Agent (and any request, authorization, consent or approval of any
         Lender given before receipt of such notice is conclusive and binding on
         each subsequent holder, assignee or transferee of or Participant in
         that Lender's Pro Rata Part of the Principal Debt), (c) are not deemed
         to have notice of the occurrence of a Default unless a responsible
         officer of Agent, who handles matters associated with the Loan
         Documents and transactions thereunder, has actual knowledge or Agent
         has been notified by a Lender or Borrower, and (d) are entitled to
         consult with legal counsel (including counsel for Borrower),
         independent accountants, and other experts selected by Agent (and/or
         any such Lenders, as the case may be) and are not liable for any action
         taken or omitted to be taken in good faith by it in accordance with the
         advice of counsel, accountants, or experts.

                  (e)    Limitation of Agent's Liability.

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

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

                           (iii)   Agent is not responsible to any Lender or any
                  Participant for, and each Lender represents and warrants that
                  it has not relied upon Agent in respect of, (i) the





                                       47

<PAGE>   53



                  creditworthiness of Borrower and the risks involved to that
                  Lender, (ii) the effectiveness, enforceability, genuineness,
                  validity or due execution of any Loan Document (other than by
                  Agent), (iii) any representation, warranty, document,
                  certificate, report or statement made therein (other than by
                  Agent) or furnished thereunder or in connection therewith,
                  (iv) the adequacy of any collateral now or hereafter securing
                  the Obligations or the existence, priority or perfection of
                  any Lien now or hereafter granted or purported to be granted
                  on the collateral under any Loan Document, or (v) the
                  observance of or compliance with any of the terms, covenants
                  or conditions of any Loan Document on the part of Borrower.
                  EACH LENDER AGREES TO INDEMNIFY AGENT AND ITS REPRESENTATIVES
                  AND HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH
                  LENDER'S PRO RATA PART OF) ANY AND ALL LIABILITIES,
                  OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
                  SUITS, COSTS, REASONABLE EXPENSES AND REASONABLE DISBURSEMENTS
                  OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE IMPOSED ON,
                  ASSERTED AGAINST, OR INCURRED BY THEM IN ANY WAY RELATING TO
                  OR ARISING OUT OF THE LOAN DOCUMENTS OR ANY ACTION TAKEN OR
                  OMITTED BY THEM UNDER THE LOAN DOCUMENTS IF AGENT AND ITS
                  REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH AMOUNTS BY
                  BORROWER. ALTHOUGH AGENT AND ITS REPRESENTATIVES HAVE THE
                  RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR
                  OWN ORDINARY NEGLIGENCE, AGENT AND ITS REPRESENTATIVES DO NOT
                  HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS
                  OR THEIR OWN FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

                  (f)    Default; Collateral. If Agent receives notice of a
         Default from Borrower or any Lender, Agent shall promptly notify
         Lenders of such Default and Lenders agree to promptly confer in order
         that Required Lenders or Lenders, as the case may be, may agree upon a
         course of action for the enforcement of the Rights of Lenders. Unless
         and until Agent receives directions from Required Lenders, Agent shall
         refrain from taking any action (without incurring any liability to any
         Person for so refraining), provided that, unless and until Agent has
         received such directions, Agent may, at its option, take such actions
         as it deems appropriate without the direction of Required Lenders in
         circumstances where the ability of Lenders to recover the Obligations
         may otherwise be materially impaired. In actions with respect to any
         property of any Company, Agent is acting for the ratable benefit of
         each Lender. Agent shall hold, for the ratable benefit of all Lenders,
         any security it receives for the Obligations or any guaranty of the
         Obligations it receives upon or in lieu of foreclosure.

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

                  (h)    Relationship of Lenders. The Loan Documents, and the
         documents delivered in connection therewith, do not create a
         partnership or joint venture among Agent and Lenders or among Lenders.

                  (i)    Collateral Matters.

                         (i)       Each Lender authorizes and directs Agent to
                  enter into the Security Documents for the ratable benefit of
                  Lenders. Each Lender agrees that any action taken by Agent
                  concerning any Collateral with the consent of, or at the
                  request of, Required Lenders or all Lenders, as the case may
                  be, in accordance with the provisions of this Agreement, the
                  Security Documents or the other Loan Documents, and the
                  exercise by Agent (with the consent of, or at the request of,
                  Required Lenders or all Lenders, as the case may be) of powers
                  concerning the Collateral set forth in any Loan Document,
                  together with other reasonably incidental powers, shall be
                  authorized and binding upon all Lenders.

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

                           (iii)   Agent has no obligation whatsoever to any
                  Lender or to any other Person to assure that the Collateral
                  exists or is owned by any Company or is cared for, protected
                  or insured or has been encumbered or that the Liens granted to
                  Agent for the benefit of Lenders under the Security Documents
                  have been properly or sufficiently or lawfully created,
                  perfected, protected or enforced, or are entitled to any
                  particular priority.

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

                           (v)     Lenders irrevocably authorize Agent, at its
                  option and in its discretion, to release any lien upon any
                  Collateral (i) upon full payment of the Obligations; (ii)
                  constituting property being sold or disposed of as permitted
                  under SECTIONS 6.17 and 7.5, if Agent determines that the
                  property being sold or disposed is being sold or disposed in
                  accordance with the requirements and limitations of SECTIONS
                  6.17 and 7.5 and Agent concurrently receives all mandatory
                  prepayments with respect thereto, if any; (iii) constituting
                  property in which such Company did not own any interest at the
                  time such lien was granted or at any time thereafter; (iv)
                  constituting property leased to such Company under a lease
                  that has expired or been terminated in a transaction permitted
                  under this Agreement or is about to expire and that has not
                  been, and is not intended by such Company to be, renewed; (v)
                  consisting of an instrument evidencing Indebtedness pledged to
                  Agent (for the benefit of Lenders), if the Indebtedness
                  evidenced thereby has been paid in full; or (vi) if approved,
                  authorized or ratified in writing by Required Lenders subject
                  to SECTION 11.13(b)(v). Upon request by Agent at any time,
                  Lenders will confirm in writing Agent's authority to release
                  particular types or items of Collateral under this SECTION
                  10.7(i).

                  (j)    Amendments. The affirmative vote of Required Lenders
         shall be required for Amendments, waivers and similar actions, except
         100% of the affirmative vote of all Lenders shall be required for any
         changes in interest rates, the rates of any fee (excluding Agent's
         fee), payment dates, extensions of commitment, or release of material
         Collateral.

                  (k)    Benefits of Agreement. None of the provisions of this
         ARTICLE X inure to the benefit of any Company or any other Person other
         than Agent and Lenders; consequently, no Company nor any such other
         Person is entitled to rely upon, or to raise as a defense, in any
         manner whatsoever, the failure of Agent or any Lender to comply with
         these provisions.

                                   ARTICLE XI
                                  MISCELLANEOUS

         11.1     Successors and Assigns. This Agreement is entered into for the
benefit of the parties hereto and their respective successors and assigns. It
shall be binding upon and shall inure to the benefit of such parties and their
respective successors and assigns. The rights and obligations of the Companies
hereunder, under the Notes, the other Security Documents and any other documents
to which it is a party may not be assigned without Lenders' prior written
consent.

         11.2     Participations. Subject to the provisions of this section and
in accordance with applicable Law, any Lender may, in the ordinary course of its
commercial banking business, at any time sell to one or more Persons (each a
"PARTICIPANT") participating interests in its portion of the Obligations. The
selling Lender shall remain a "Lender" under this Agreement (and the Participant
shall not constitute a "Lender" under this Agreement) and its obligations under
this Agreement shall remain unchanged. The selling Lender shall remain solely
responsible for the performance of its obligations under the Loan Documents and
shall remain the holder of its share of the Principal Debt for all purposes
under this Agreement. Borrower and Agent shall continue to deal solely and
directly with the selling Lender in connection with that Lender's Rights and
obligations under the Loan Documents. Participants have no Rights under the Loan
Documents, other than certain voting Rights as provided below. Subject to the
following, each Lender may obtain (on behalf of its Participants) the benefits
of ARTICLE II with respect to all participations in its part of the Obligations
outstanding from time to time so long as Borrower is not obligated to pay any
amount in excess of the amount that would be due to that Lender under ARTICLE II
calculated as though no participations have been made. No Lender may sell any
participating interest under which the Participant has any Rights to approve any
amendment, modification or waiver of any Loan Document, except to the extent the
amendment, modification or waiver extends the due date for payment of any
principal, interest or fees due under the Loan Documents, reduces the interest
rate or the amount of principal or fees applicable to the Obligations (except
reductions contemplated by this Agreement), or releases any collateral, if any,
for the Obligations (other than releases of collateral permitted by SECTION 7.5
and SECTION 10.7(i)). However, if a Participant is entitled to the benefits of
ARTICLE II or a Lender grants Rights to its Participants to approve amendments
to or waivers of the Loan Documents respecting the matters described in the
previous sentence, then that Lender must include a voting mechanism in the
relevant participation agreement whereby a majority of its portion of the
Obligations (whether held by it or participated) shall control the vote for all
of that Lender's portion of the Obligations. Except in the case of the sale of a
participating interest to another Lender, the relevant participation agreement
shall prohibit the Participant from transferring, pledging, assigning, selling
participations in, or otherwise encumbering its portion of the Obligations.

         11.3     Assignments. Subject to the provisions of this section, any
Lender may at any time, in the ordinary course of its commercial banking
business, (i) without the consent of Borrower or Agent, assign all or any part
of its Rights and obligations under the Loan Documents to any of its Affiliates
which has sufficient resources with which to honor its obligations under this
Agreement (each a "PURCHASER") and (ii) if no Default exists, upon the prior
written consent of Borrower (which will not be unreasonably withheld) and Agent,
assign





                                       50

<PAGE>   56



to any other Person(each of which is also a "PURCHASER") a proportionate part
(not less than $7,500,000 and an integral multiple of $500,000) of all or any
part of its Rights and obligations under the Loan Documents. In each case, the
Purchaser shall assume those Rights and obligations under an assignment
agreement substantially in the form of the attached EXHIBIT F. Each assignment
under this SECTION 11.3 shall include a ratable interest in the assigning
Lender's Rights and obligations under this Agreement. Upon (i) delivery of an
executed copy of the assignment agreement to Borrower and Agent and (ii) payment
of a fee of $3,500 from the transferor to Agent, from and after the assignment's
effective date (which shall be after the date of delivery), the Purchaser shall
for all purposes be a Lender party to this Agreement and shall have all the
Rights and obligations of a Lender under this Agreement to the same extent as if
it were an original party to this Agreement with commitments as set forth in the
assignment agreement, and the transferor Lender shall be released from its
obligations under this Agreement to a corresponding extent, and, except as
provided in the following sentence, no further consent or action by Borrower,
Lenders or Agent shall be required. Upon the consummation of any transfer to a
Purchaser under this SECTION 11.3, the then-existing SCHEDULE 1 shall
automatically be deemed to reflect the name, address, and Committed Amount of
such Purchaser, Agent shall deliver to Borrower and Lenders an amended SCHEDULE
1 reflecting those changes, Borrower shall execute and deliver to each of the
transferor Lender and the Purchaser a promissory note in the form of EXHIBIT A
in the face amount of its respective Committed Amount under this Agreement
following transfer, and, upon receipt of such note, the transferor Lender shall
return to Borrower the promissory note previously delivered to it under this
Agreement. A Purchaser is subject to all the provisions in this section as if it
were a Lender signatory to this Agreement as of the date of this Agreement. Any
Lender may at any time, without the consent of Borrower or Agent, assign all or
any part of its Rights under the Loan Documents to a Federal Reserve Bank
without releasing the transferor Lender from its obligations thereunder.
Notwithstanding any contrary provision in this Agreement, a Lender may not sell
or participate any of its interests for a purchase price that, directly or
indirectly, reflects a discount from face value, without first offering the sale
or participation to the other Lenders on a Pro Rata basis (which must be
accepted or rejected within five Business Days after the offer).

         11.4     Notices. Any notice, demand or document which either party is
required or may desire to give hereunder shall be in writing and, except to the
extent provided in the other provisions of this Agreement, given by messenger,
telecopy or other electronic transmission, or United States registered or
certified mail, postage prepaid, return receipt requested, addressed to such
party at its address and telecopy number shown below, or at such other address

Any notice delivered or made by messenger, telecopy, or United States mail shall
be deemed to be given on the date of actual delivery as shown by messenger
receipt, the addressor's telecopy machine confirmation or other verifiable
electronic receipt, or the registry or certification receipt. Agent or Lenders
need not delay action on notice transmitted orally by an authorized officer of
Borrower to Agent or Lenders until receipt of written confirmation of such
notice. In the event that a discrepancy exists between the notice received by
Agent or Lenders orally and the written confirmation, or in the absence of a
written confirmation, the oral notice, as understood by Agent or Lenders will be
deemed the controlling and proper notice.

         11.5     Exercise of Rights; No Waivers. Neither the failure nor any
delay on the part of any party hereto to exercise any right, remedy, power,
privilege or option under this Agreement shall operate as a waiver of such or
any other right, remedy, power, privilege or option. No single or partial
exercise of any right, remedy, power, privilege or option under this Agreement
shall preclude any other or further exercise thereof or the exercise of any
other right, remedy, power, privilege or option. No waiver of any right, remedy,
power, privilege or option with respect to any occurrence shall be construed as
a waiver of such right, remedy, power, privilege or option with respect to any
subsequent or other occurrence. No waiver whatever shall be valid unless in
writing and signed by an officer of the party to whom such waiver applies and
then only to the extent therein set forth.

         11.6     Release to Public. Except as may be required by law, rule or
regulation (including those promulgated by any federal or state securities law
authority) or in response to or in connection with arbitration proceedings or
legal process or in any legal proceeding to enforce or have interpreted the
Security Documents or any other document or instrument executed in connection
with the Security Documents, and such filings as are necessary or appropriate to
create, maintain and perfect liens and security interests contemplated hereby,
no party shall release this Agreement or any other document, agreement or
instrument relating to or executed in conjunction with this Agreement, or
disclose the substantive terms hereof or thereof, except to its attorneys,
accountants or engineers, participants and potential Lenders on a need-to-know
basis, without the prior express written consent of the other party. Without
limitation of the foregoing, neither party or any of their respective Affiliates
shall issue any press release or make any other public announcement relating to
this Agreement without the written approval of the other party; provided,
however, that Agent shall have the right to publish a "tombstone" announcement
regarding this Agreement, which announcement shall be approved by Borrower (such
approval not to be unreasonably withheld).

         11.7     Waiver of Jury Trial. TO THE MAXIMUM EXTENT NOT PROHIBITED BY
LAW, EACH OF THE UNDERSIGNED (AND IN THE CASE OF BORROWER, FOR ITSELF AND EACH
OTHER COMPANY) HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT
WHICH IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN
DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY.

         11.8     Governing Law. The Loan Documents (other than the Security
Documents to the extent they may be governed by Texas law or the laws of any
other State of the United States where the Collateral is located) are to be
performed in the State of New York. Except to the extent that any of the
Security Documents are expressly stated to be governed by Texas law, the Loan
Documents, and all transactions provided for herein or therein shall be governed
by, interpreted and construed under, and in connection with, the laws of the
State of New York without regard to its conflicts of laws provisions.

         11.9     Benefits of Agreement. Subject to SECTION 10.7, the benefits
of this Agreement shall not inure to any third party. Notwithstanding anything
contained in the Security Documents, or any conduct or course of conduct by the
parties hereto, before or after signing the Security Documents, this Agreement
shall not be construed as creating any rights, claims or causes of action
against Lenders, or any of their officers, directors, agents or employees by any
Person other than Borrower.

         11.10    Invalid Provisions. Any section, clause, subsection, sentence,
paragraph, provision or portion thereof of this Agreement held by a court of
competent jurisdiction to be invalid, illegal, or ineffective shall not impair,
invalidate or nullify the remainder of this Agreement, but the effect thereof
shall be confined to the section, clause, subsection, sentence, paragraph or
provision, or portion thereof so held to be invalid, illegal or ineffective.

         11.11    Headings. The headings, captions and arrangements contained in
this Agreement have been inserted for convenience only and shall not be deemed
in any manner to modify, explain, enlarge or restrict any of the provisions
hereof.

         11.12    Advice of Legal Counsel. Borrower, Agent and Lenders
acknowledge that each of them has had the benefit of legal counsel of its own
choice and has been afforded an opportunity to review the Loan



                                       53

<PAGE>   59



Documents with their legal counsel and that the Loan Documents shall be
construed as if jointly drafted by Borrower and Lenders.

         11.13    Amendments, Consents, Conflicts and Waivers.

                  (a)    Unless otherwise specifically provided, (i) this 
         Agreement may be amended only by an instrument in writing executed by
         Borrower, Agent and Required Lenders and supplemented only by documents
         delivered or to be delivered in accordance with the express terms of
         this Agreement, and (ii) the other Loan Documents may only be the
         subject of an amendment, modification or waiver that has been approved
         by Required Lenders and the respective parties thereto.

                  (b)    Any amendment, consent or waiver under this Agreement
         or any Loan Document that purports to accomplish any of the following
         must be in writing and executed by Borrower and Agent and executed (or
         approved, as the case may be) by each Lender: (i) extend the due date
         or decrease the amount of any scheduled payment of the Obligation
         beyond the date specified in the Loan Document; (ii) decrease any rate
         or amount of interest, fees or other sums payable to Agent or Lenders
         under this Agreement (except such reductions as are contemplated by
         this Agreement); (iii) change the definition of "Committed Amount,"
         "Commitment Percentage," "Required Lenders," "Maturity Date," "Total
         Commitment" or any of the defined terms used in the financial covenants
         contained in ARTICLE VI; (iv) increase or decrease any one or more
         Lenders' Committed Amounts except as provided in this Agreement; (v)
         consent to the release of any portion of the Collateral under the
         Security Documents (except for such releases as are permitted under the
         terms of this Agreement) having a value equal to or greater than
         $1,000,000 (or if the value of such Collateral when added to the value
         of all other Collateral released during the immediately preceding 12
         month period is equal to or greater than $4,000,000); (vi) change the
         provisions of SECTION 11.7 to the detriment of any Lender; (vii) change
         any provision requiring ratable distributions to Lenders; (viii)
         subject any Lender to a greater obligation than expressly provided in
         this Agreement; or (ix) change this SECTION 11.13(b) or any other
         matter specifically requiring the consent of all Lenders under this
         Agreement.

                  (c)    Any conflict or ambiguity between the terms and 
         provisions of this Agreement and terms and provisions in any other Loan
         Document is controlled by the terms and provisions of this Agreement.

                  (d)    No course of dealing or any failure or delay by Agent,
         any Lender, or any of their respective Representatives with respect to
         exercising any Right of Agent or any Lender under this Agreement
         operates as a waiver thereof. A waiver must be in writing and signed by
         Agent and Lenders (or Required Lenders, if permitted under this
         Agreement) to be effective, and a waiver will be effective only in the
         specific instance and for the specific purpose for which it is given.

         11.14    Multiple Counterparts. This Agreement may be executed
simultaneously in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute but one and the same
instrument.

         11.15    Usury Savings Clause. It is the intention of the parties
hereto to comply with applicable usury laws (now or hereafter enacted);
accordingly, notwithstanding any provision to the contrary in this Agreement and
the other Security Documents or any other document related hereto, in no event
shall this Agreement or any such other document require the payment or permit
the collection of interest in excess of the maximum 




                                       54

<PAGE>   60



amount permitted by such laws. If from any circumstances whatsoever, fulfillment
of any provision of this Agreement or of any other document pertaining hereto or
thereto, shall involve transcending the limit of validity prescribed by law for
the contracting for, collection or charging of interest, then, ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any such circumstances Lender shall ever receive anything of value as
interest or deemed interest by applicable law under the Loan Documents or any
other document pertaining hereto or otherwise an amount that would exceed the
highest lawful rate, such amount that would be excessive interest shall be
applied to the reduction of the principal amount owing under the Notes or on
account of any other indebtedness of Borrower to Lenders, and not to the payment
of interest, or if such excessive interest exceeds the unpaid balance of
principal of such indebtedness, such excess shall be refunded to Borrower. In
determining whether or not the interest paid or payable with respect to any
indebtedness of Borrower to Lenders, under any specified contingency, exceeds
the highest lawful rate, Borrower and Lenders shall, to the maximum extent
permitted by applicable law, (a) characterize any non-principal payment as an
expense, fee or premium rather than as interest, (b) exclude voluntary
prepayments and the effects thereof, (c) amortize, prorate, allocate and spread
the total amount of interest throughout the full term of such indebtedness so
that the actual rate of interest on account of such indebtedness does not exceed
the maximum amount permitted by applicable law, and/or (d) allocate interest
between portions of such indebtedness, to the end that no such portion shall
bear interest at a rate greater than that permitted by applicable law.

         11.16    Hedges; Cash Collateral. On the Termination Date, upon the
cancellation of the Total Commitment under SECTION 2.8, during the continuance
of a Default under SECTION 9.1(d) or 9.1(e), or upon any demand by Agent during
the continuance of any other Default, the Companies shall provide to Agent, for
the benefit of Agent or any Lender which is a party to a Hedge with any Company,
upon the written request from Agent or such Lender, as applicable, cash
collateral or other collateral acceptable to Agent or such Lender, as
applicable, in an amount equal, at all times, to 110% of Borrower's "Exposure"
(as defined in the ISDA form Master Swap Agreement) pursuant to the terms and
provisions of the standard ISDA form of Credit Support Annex (with such
modifications as may be agreed to by Borrower and Agent or such Lender, as
applicable). Borrower shall pay Agent's or Lender's, as applicable, costs and
expenses associated with such collateralization and with maintaining and
monitoring such Hedges in effect after the Termination Date or upon cancellation
of the Total Commitment under SECTION 2.8.

         11.17    Nonbusiness Days; Time. Any payment or action that is due
under any Loan Document on a non-Business Day may be delayed until the
next-succeeding Business Day (but interest shall continue to accrue on any
applicable payment until payment is in fact made) unless the payment concerns a
Eurodollar Rate Advance, in which case if the next-succeeding Business Day is in
the next calendar month, then such payment shall be made on the next-preceding
Business Day. Unless otherwise indicated, all time references (e.g., 10:00 a.m.)
are to New York, New York time.

         11.18    Entirety. THE LOAN DOCUMENTS REPRESENT 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.

                                MASTER COMMODITY
                                 SWAP AGREEMENT

                            DATED AS OF MAY 15, 1998
                                     BETWEEN
                       CHRISTIANIA BANK OG KREDITKASSE ASA
                                       AND
                          MICHAEL PETROLEUM CORPORATION


         CHRISTIANIA BANK OG KREDITKASSE ASA ("BANK") may from time to time
enter into commodity swaps based on fixed and floating rates of interest or on
fixed and floating prices of crude oil, natural gas or related products (each, a
"SWAP") with MICHAEL PETROLEUM CORPORATION, a Texas corporation (the
"COUNTERPARTY"). The specific terms and conditions of each Swap shall be set
forth in Bank's telex or facsimile confirmation in the form of Exhibit A hereto
("CONFIRMATION"), reconfirmed by telex or facsimile by the Counterparty in the
form of Exhibit B hereto ("RECONFIRMATION"), which telexes and/or facsimiles
together with the following terms and conditions shall constitute the terms and
conditions of each such Swap, and all Swaps at any time and from time to time
outstanding shall collectively constitute a single agreement (the "AGREEMENT")
between Bank and the Counterparty, it being understood that the parties would
not otherwise enter into any Swap. Counterparty and Bank intend that each such
Swap and the Agreement, (i) shall constitute swap agreements that comply with
the safe harbor standards set forth in the Commodity Futures Trading Commission
("CFTC") Policy Statement Concerning Swap Transactions, 54 Fed. Section Reg.
30694 (1989), (ii) shall constitute options that are within the trade option
exemption promulgated by the CFTC, 17 C.F.R. 32.4(a), and (iii) shall constitute
swap agreements that comply with the standards set forth in Part 35 of Chapter 1
of Title 17 of the Code of Federal Regulations.

         Accordingly, Bank and the Counterparty agree as follows:

         1.       DEFINED TERMS. The terms "BANK," "SWAP," "COUNTERPARTY," 
"CONFIRMATION," "RECONFIRMATION," and "AGREEMENT" are defined in the immediately
preceding paragraph.

         The terms (if applicable) "FIXED PRICE," "FIXED PRICE PAYOR," "FLOATING
PRICE PAYOR," "QUANTITY PER DETERMINATION PERIOD," "QUANTITY MEASUREMENT,"

FLOATING PRICE" equals (x) the sum of the Floating Price for each Trading Day in

amount.

         (c)      Amounts owed pursuant to Section 3(a) or 3(b) shall be due and
payable on the applicable Payment Date. If such amounts or any other amounts
payable under this Agreement are not paid when due, such overdue amounts shall
bear interest for each day until paid in full, payable on demand, at a rate per
annum equal to the Default Rate in effect from time to time on the basis of the
actual number of days elapsed from the due date thereof and on the basis of a
year of 360 days.

         (d)      All payments under this Agreement shall be made in U.S.
dollars via wire transfer in Federal or other funds immediately available in New
York City to the owed party's Designated Account. All payments under this
Agreement will be made without any deduction or withholding for or on account of
any Tax unless such deduction or withholding is required by any applicable law,
as modified by the practice of any relevant governmental revenue authority, then
in effect. If a party is so required to deduct or withhold, then the party ("X")

         requirement;

                  2)       pay to the relevant authorities the full amount
         required to be deducted or withheld (including the full amount required
         to be deducted or withheld from any additional amount paid by X to Y
         under this Section 3(d)) promptly upon the earlier of determining that
         such deduction or withholding is required or receiving notice that such
         amount has been assessed against Y;

                  3)       promptly forward to Y an official receipt (or a
         certified copy), or other documentation reasonably acceptable to Y,
         evidencing such payment to such authorities; and

                  4)       if such Tax is an Indemnifiable Tax, pay to Y, in
         addition to the payment to which Y is otherwise entitled under this
         Agreement, such additional amount as is necessary to ensure that the
         net amount actually received by Y (free and clear of Indemnifiable
         Taxes, whether assessed


                                        4

<PAGE>   5



         against X or Y) will equal the full amount Y would have received had no
         such deduction or withholding been required. However, X will not be
         required to pay any additional amount to Y to the extent that Y would
         not be required to be paid for:

                           A)       the failure by Y to comply with Sections 
                  4(b) and 4(c) or

                           B)       the failure of the representations made by Y
                  in Section 5(h), 5(i) or 5(j), as appropriate, to be accurate
                  and true unless such failure would not have occurred but for
                  an Event of Change described in Section 7(a).

         4.       COVENANTS

         (a)      Each party covenants that it will comply in all material
respects with all applicable laws and orders to which it may be subject if
failure so to comply would materially impair its ability to perform its
obligations under this Agreement.

         (b)      Each party covenants that it will deliver to the other party
any forms, documents or certificates reasonably requested by the other party in
order to reduce or eliminate any required withholding or deduction for or on
account of any Taxes.

         (c)      Each party covenants that it will give notice of any failure
of a representation made by it under Sections 5(h), 5(i) or 5(j), as
appropriate, to be true and accurate promptly upon learning of such failure.

         (d)      The Counterparty covenants that at any time and from time to
time, at the expense of the Counterparty, the Counterparty will promptly execute
and deliver all further instruments and documents, and take all further action
to perfect and protect the security interests granted in the Collateral under
the other Loan Documents and hereunder or to enable Bank to exercise and enforce
rights, remedies and powers of Bank hereunder with respect to any Collateral.

         (e)      Each party covenants that all obligations arising out of this
Agreement shall be paid and settled in cash and that neither party shall have
any obligations, nor shall it be permitted, to deliver in physical form any
commodity underlying a Swap.

         5.       REPRESENTATIONS AND WARRANTIES. On the date hereof and at the
time of entering into this Agreement, each party represents and warrants that:

into and performance of this Agreement and the Confirmations or Reconfirmations,

its knowledge after reasonable inquiry, any order of a court or other agency of

         (j)      solely with respect to Bank, each payment received by it in

in the Loan Agreement) or event or condition which, with the giving of notice or
lapse of time or both, would constitute an Event of Default (as defined herein)
or Default (as defined in the Loan Agreement) or, to its knowledge, Event of
Change with respect to it has occurred and is continuing and no such event or
circumstance would occur as a result of its entering into or performing is
obligations under this Agreement;

         (l)      solely with respect to the Counterparty, all present and
future obligations of the Counterparty hereunder and under each Swap are secured

<PAGE>   8



of competent jurisdiction or as determined by the opinion of independent counsel
mutually acceptable to Bank and the Counterparty) that occurs after the date on
which a Swap is entered into which would result in the imposition of a tax in a
material amount by any government or taxing authority upon a party hereto with
respect to a payment under this Agreement which would require a party (the
"AFFECTED PARTY") to make an additional payment hereunder in a material amount
pursuant to Section 3(d) hereof (a "TAX EVENT");

         (b)      the enactment, promulgation, execution or ratification of, or
any change in or amendment to, any law (or the application or interpretation of

acceptable to Bank and the Counterparty) that occurs after the date on which a
Swap is entered into which would result in the execution and delivery of this
Agreement or the performance of any obligation of either of the parties under
this Agreement being unlawful (an "ILLEGALITY"); and

         (c)      a party consolidates or merges with or into, or transfers all
or substantially all its assets to another entity and such action does not
constitute an Event of Default under Section 6(f) and in the case of such event
with respect to a party (the "MERGED PARTY"), the other party (the "TERMINATING
PARTY") determines, in its sole and reasonable discretion, that the
creditworthiness of the Merged Party is not acceptable to the Terminating Party
(a "MERGER EVENT").

         8.       EARLY TERMINATION.

         (a)      If an Event of Default pursuant to subsection (a), (b), (c), 
(d), (e), (f), (g) or (h) of Section 6 shall have occurred and be continuing,
the non-defaulting party ("NON-DEFAULTING PARTY") may designate an early
termination date ("EARLY TERMINATION DATE") upon two Business Days' notice to
the defaulting party ("DEFAULTING PARTY"); if an Event of Default pursuant to
subsection (i) of Section 6 shall have occurred, the Early Termination Date
shall automatically be the day immediately preceding the date of such Event of
Default and no notice to the Defaulting Party shall be required. Upon the Early
Termination Date, the parties' obligations under this Agreement shall terminate,
except for the obligations contained in Section 8(b).

         (b)      Upon the Early Termination Date, (i) the Defaulting Party
shall owe the Non-Defaulting Party the sum of (I) the aggregate amount, if any,
owed by the Defaulting Party to the Non-Defaulting Party under this Agreement
and (II) any damages, costs, losses or expenses (or gain, in which case is
expressed as a negative number) resulting from the designation of the Early
Termination Date incurred by the Non-Defaulting Party, determined in a
commercially reasonable manner, and including (without limitation) any damages,
losses, costs, or expenses (or gain) incurred in obtaining, liquidating or
employing hedges against the Swap positions and in replacing the terminated
Swaps with equivalent positions; and (ii) the Non-Defaulting Party shall owe
the Defaulting Party the aggregate amount, if any, owed by the Non-Defaulting
Party to the Defaulting Party under this Agreement. Notwithstanding the
foregoing, if the amount calculated above in clauses (i) and (II) in this
Section 8(b) is a positive number, the Defaulting Party will pay it to the
Non-Defaulting Party; provided, however, that if such amount is a negative
number, the Non-Defaulting Party will pay the absolute value of that amount to
the Defaulting Party. For purposes of calculating amounts owed pursuant to
Section 3(a) of this Agreement in the event of early termination under this
Section, the Early Termination Date shall be deemed to be the last day of the
final Determination Period. Along with its designation of an Early Termination
Date, the Non-Defaulting Party shall provide its computation of damages, costs,
losses and expenses pursuant to clause (i)(II) above, in reasonable detail and
accompanied by reasonable corroborating documentation; however, the amount due
under clause (i)(II) above shall be only that amount mutually agreed upon by the
parties or, failing such agreement, that amount determined to be the average of
the calculations from Reference Market-makers, discarding the highest and lowest
quotations.


                                        8

<PAGE>   9



         The party owing the higher amount under clauses (i) and (ii) above
shall pay to the other party within two business days of the Early Termination
Date the excess of the higher amount over the smaller amount.

         9.       ACCELERATED TERMINATION.

         (a)      Upon the occurrence of an Event of Change, the party becoming
aware thereof shall promptly notify the other party specifying the nature
thereof and the affected Swaps, and both parties shall make reasonable efforts
to make arrangements to avoid the imposition of any tax contemplated by Section
7(a) or to avoid the performance of any of the obligations of either of the
parties under this Agreement from being unlawful as contemplated by Section
7(b); provided that this subsection shall not impose on either party any
obligation other than to negotiate in good faith to make such arrangements as
will not adversely affect either of the parties.

         (b)      If an Event of Change shall have occurred and be continuing,
and if an arrangement is not made pursuant to Section 9(a) within fifteen (15)
days, then the Affected Party (in the event of a Tax Event), the Terminating
Party (in the event of a Merger Event), or either party (in the event of an
Illegality) may designate an accelerated termination date ("ACCELERATED
TERMINATION DATE") upon two Business Days' notice to the other party. Upon the
Accelerated Termination Date, the parties' obligations under this Agreement
shall terminate, except for the obligations contained in the remainder of this
subsection. The party having the larger net gain or smaller net loss as a
consequence of the termination of the parties' obligations under this Agreement
shall pay to the other party an amount equal to one-half of the difference
between such net gain and net loss. Such net gain and net loss shall be
determined in a commercially reasonable manner and shall include (without
limitation) any damages, losses, costs, or expenses incurred in obtaining,
liquidating or employing hedges against the Swap positions and in replacing the
terminated Swaps with equivalent positions. Along with its designation of an
Accelerated Termination Date, the party making such designation shall provide
its computation of such net gain or net loss to both parties as a consequence of
the termination of the parties' obligations under this Agreement, in reasonable
detail and accompanied by reasonable corroborating documentation; however, the
amount due under this subsection shall be only that amount mutually agreed upon
by the parties or, failing such agreement, that amount determined to be the
average of the calculations from Reference Market-makers, discarding the highest
and lowest quotations. The intent of this subsection is to leave each party in
an equal financial position (vis-a-vis this Agreement) as a result of an Event
of Change.

         10.      COLLATERAL. The obligations of the Counterparty hereunder are
secured by the Collateral, and the Counterparty shall deliver to Bank such
documents as shall be reasonably requested by Bank to perfect and enforce the
Bank's liens and security interests with respect thereto.

         11.      OFFICER'S CERTIFICATE. Promptly after the execution of this
Agreement, each party shall deliver to the other party an officer's certificate
as to the due authorization, execution and delivery of this Agreement, including
the specimen signature(s) of the officer(s) executing this Agreement.

         12.      WAIVERS. Any failure or delay by either party to exercise any
right, in whole or in part, hereunder shall not be construed as a waiver of the
right to exercise the same or any other right at any time and from time to time
hereunder.

         13.      ASSIGNMENT. Except as may be contemplated for purposes of
Section 9(a), neither this Agreement, any right or interest herein nor any
payment due to either party hereunder may be assigned as security or otherwise
by the Counterparty and any purported assignment in violation of this provision
shall



                                       9

<PAGE>   10



be null and void; provided, however, that Bank may assign its rights hereunder
to (i) any affiliate of Bank, or (ii) another financial institution or
accredited investor, which in either case shall have a similar credit rating as
Bank.

         14.      OPINION OF COUNSEL. Promptly after execution of this
Agreement, the Counterparty shall deliver to Bank an opinion of counsel in form
