                    11 1/2% SENIOR NOTES DUE 2005, SERIES B
                              FOR ALL OUTSTANDING

                                       OF
                         MICHAEL PETROLEUM CORPORATION

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

      THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
______, __________, 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 has 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 (as defined) governing the Old
Notes.  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 (as defined), 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 Equity Offerings (as defined),
provided that at least 65% of the aggregate principal amount of the Notes
originally issued remains outstanding following each such 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 (as defined), 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 pari passu in right of payment with all existing and future senior
indebtedness and other senior obligations of the Company, and senior in right
of payment to all future subordinated indebtedness of the Company.  Borrowings
under the Credit Facility (as defined) will be 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."  The maximum amount of borrowings under the Credit
Facility will be limited by the terms of the Notes. At December 31, 1997, after
giving pro forma effect to the Transactions (as defined) and to the sale of the
Old Notes and the application of the proceeds therefrom, the Company would have
had no outstanding senior indebtedness in addition to the Notes.

    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 ______, __________, 1998, unless
extended (the "Expiration Date"). 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 (as defined), 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."

INVESTMENT IN THE NEW NOTES, SEE "RISK FACTORS" BEGINNING ON PAGE 11.  

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

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

                                  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
(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.

                               THE NOTE OFFERING

The Old Notes . . . . . . . .     The Old Notes were sold by the Company on
                                  April 2, 1998, to the Initial Purchasers
                                  pursuant to a Purchase Agreement.  The
                                  Initial Purchasers resold the Old Notes to
                                  qualified institutional buyers pursuant to
                                  Rule 144A under the Securities Act or outside
                                  the United States within the meaning of
                                  Regulation S under the Securities Act.

Registration Statement  . . .     The Registration Rights Agreement granted the
                                  holders of the Old Notes certain exchange and
                                  registration rights.  The Exchange Offer is
                                  intended to satisfy those exchange rights,
                                  which terminate upon consummation of the
                                  Exchange Offer.  If applicable law or
                                  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
                                  to file a shelf registration covering resales
                                  of Transfer Restricted Notes (as defined in
                                  the Registration Rights Agreement).

                               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."

Interest on the New Notes
  and Old Notes   . . . . . .     Interest on each New Note will accrue from
                                  the date of issuance of the Old Note for
                                  which the New Note is exchanged or from the
                                  date of the last periodic payment of interest
                                  on such Old Note, whichever is later. No
                                  interest will be paid on Old Notes which are
                                  exchanged for New Notes, and holders of such
                                  Old Notes will be deemed to have waived the
                                  right to receive interest accrued thereon to
                                  the date of exchange.

(1)      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 January 1, 1997.

(2)      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

         Notes thereto included elsewhere in this Prospectus.

(3)      Earnings were insufficient to cover fixed charges by $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.  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.

(4)      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 December 31, 1997.

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

(6)      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.

(7)      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.

(9)      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 December 31, 1997, 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 the Credit Facility. 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.

    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 terms of the Credit Facility are expected to
restrict the Company's ability to sell assets and the Company's use of the
proceeds therefrom. 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 pari
passu with all existing and future Senior Indebtedness of the Company,
including any indebtedness to be 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 instruments governing the Credit Facility will 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 will be 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 expects to have 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 is subject to a variety of federal, state and local
governmental laws and regulations related to the storage, use, discharge and
disposal of toxic, volatile or otherwise hazardous materials. 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

    Although the Company does not expect to incur significant expenditures to
address Year 2000 issues, there can be no assurance that this will be the case.
Additionally, the ability of third parties with whom the Company transacts
business to adequately address their Year 2000 issues is outside the Company's
control. There can be no assurance that the failure of the Company or such
third parties to adequately address their respective Year 2000 issues will not
have a material adverse effect on the Company's business, financial condition
and results of operations.

                               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.  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
____, _____________, 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.

<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.

    proceeds therefrom, the exchange of the Old Notes for New Notes, the

    January 1, 1997.

(2) 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 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

    pro forma year ended December 31, 1997.  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.

    value data as of December 31, 1995 was prepared by Mohajir & Associates,

(7) 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.

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

    The following discussion and analysis should be read in conjunction with
"Selected Historical and Pro Forma Financial, Operating and Oil and Natural Gas
Reserve Information," the Financial Statements of the Company and the Notes
thereto and the Unaudited Pro Forma Financial Statements of the Company and the
Notes thereto included elsewhere in this Prospectus.

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.

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.

    Depreciation, depletion and amortization ("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.





                                      -31-
<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

    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 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.

    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 expects to enter into the Credit Facility, as
described below under "--Financing Arrangements."

    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. 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."

    Subject to the restrictions and covenants of the Indenture, the Company
expects to enter into a new reducing revolving credit facility (the "Credit
Facility") with a syndicate of lenders, including Christiania Bank og
KreditKasse ("Christiania"), which will provide 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, pro tanto, the
availability of loans under the Credit Facility. Under the Credit Facility, the
principal balance outstanding will be due and payable on the fourth anniversary
of its closing date, 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 the first anniversary date of the
closing date of the Credit Facility, and continuing until its stated maturity,
the maximum amount available for borrowings and letters of credit 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 and (ii) adjusted for sales of collateral
having an aggregate value exceeding the lesser of $4.0 million per year or 5%
of 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 (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 will be 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 foregoing description of the Credit Facility is based upon a commitment
letter dated March 23, 1998 executed by Christiania and the Company. Initial
funding under the Credit Facility is subject to the negotiation, execution and
delivery of definitive loan documents on or before May 31, 1998, as well as
certain additional conditions, including the sale of the Old Notes, the
repayment of the T.E.P. Financing debt and the closing of the Transactions.
There can be no assurance that the Company will enter into any definitive loan
documents containing the terms described, or at all.

</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.
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

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 Company does not expect the adoption of SFAS No. 130 to
have a material effect on the Company's financial position, results of
operations or cash flows.

    In June 1997, the FASB also 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 also 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.

                            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 leashold 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 designates as "proved undeveloped" only those potentially
productive locations that are immediately adjacent to a producing well in the
same fault block. All other potential locations are considered "probable
undeveloped" due to the complex geology of the Lobo Trend. Since 1982, the
Company's success rate has not varied significantly among drilling locations
designated as proved or probable. The Company believes the existence of
multiple pay sands reduces the potential drilling risk in the area.

    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.

    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.

    From January 1, 1998 through March 31, 1998, the Company participated in
drilling activities on 2 gross (1.33 net) wells. Of the 2 gross (1.33 net)
wells, 2 gross (1.33 net) wells are being completed, or have been completed as
commercial producers, no wells were dry holes and 1 gross (0.7 net) well was
being drilled.  As of May 8, 1998, this well is being completed as a
commercial producer.

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 a Natural Gas Sales Agreement
dated 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.

COMPETITION

    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.

    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.

    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 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.

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 a 7.5% 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
below:

    Notwithstanding the foregoing, prior to April 1, 2001, the Company may
redeem 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, thereon to the date
of redemption, with all or a portion of the aggregate net proceeds received by
the Company from one or more Equity Offerings, provided that (i) at least 65%
of the aggregate principal amount of the Notes originally issued remains
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
of each such Equity Offering.

<PAGE>   58
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"). 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 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 [are expected to] prohibit, and future
Bank Credit Facilities or other agreements relating to Senior Indebtedness of
the Company to which the Company becomes a party 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, is [expected
to] 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
Directors of the Company.

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
liabilities incurred or assumed on such date), but excluding liabilities under
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.

    "Asset Sale" means any sale, issue, lease, transfer, exchange or other

    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

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

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

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.

    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.

            CERTAIN 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 purchase the 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 Notes as a "capital asset" within the
meaning of section 1221 of the Code.  EACH HOLDER OF OLD NOTES SHOULD 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 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 Notes
immediately before the exchange.

STATED INTEREST AND ORIGINAL ISSUE DISCOUNT

    The stated interest on the 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 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 Notes are issued, is remote.
The Company believes that the likelihood of a change in the interest rate on
the Notes is 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 Notes will be considered to be issued with original issue discount
("OID") if, and to the extent, the stated redemption price at maturity of the
Notes (which, for these purposes, will be its stated principal amount) exceeds
the issue price of the Notes. The amount of OID is, however, considered de
minimis and deemed to be zero if such excess is less than  1/4 of 1% of the
stated redemption price at maturity multiplied by the number of complete years
to maturity.  It is anticipated that the Notes will be issued with OID in
excess of the de minimis threshold.

    Assuming the Notes have been issued with OID, a holder (regardless of its
method of accounting) will be required to include in income the sum of the
daily portions of OID with respect to such 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 Note at the beginning of the accrual period multiplied by the yield to
maturity of the Note. The adjusted issue price of a Note at the beginning of
any accrual period is the issue price of the Note increased by the Accrued OID
for all prior accrual periods (less all payments made on the Notes other than
payments of stated interest on the Notes). The Company will annually furnish to
record holders of the Notes and to the IRS information with respect to any OID
accruing during the calendar year as may be required by applicable regulations.





                                      -77-
<PAGE>   82
RULES AFFECTING HIGH YIELD DEBT INSTRUMENTS

    Sections 163(e)(5) and (i) of the Code affect the treatment of interest on
applicable high yield debt obligations maturing more than five years from the
date of issuance ("AHYDOs"). The rules are complex and ambiguous in many
respects, and their full potential application to the Notes cannot be
anticipated with precision.

    The Notes will constitute AHYDOs if (i) the Notes have "significant
original issue discount" within the meaning of the Code and (ii) the yield to
maturity of the Notes is equal to or greater than the sum of the relevant
applicable federal rate (the "AFR") for the month in which the Notes are
issued, plus five percentage points. Based upon their terms, the Notes may have
"significant original issue discount." The relevant AFR for mid-term debt
instruments issued in April 1998 is 5.62% compounded semiannually. [The Company
cannot yet ascertain whether the Notes will actually constitute AHYDOs under
the foregoing rules. If the Notes are AHYDOs, as described above, a portion of
the tax deductions that would otherwise be available to the Company in respect
of the Notes will be deferred or disallowed, which, in turn, might reduce the
after-tax cash flows of the Company. More particularly, if the Notes constitute
AHYDOs, the Company will not be entitled to deduct OID that accrues with
respect to the Notes until amounts attributable to OID are paid in cash or
property (excluding, however, capital stock of the Company or a related
entity).]

    In addition, if the yield to maturity of the Notes exceeds the sum of the
relevant AFR plus six percentage points, such excess amount called the "Excess
Yield," the "disqualified portion" of the OID accruing on the Notes, will be
characterized as a nondeductible dividend with respect to the Company. The
"disqualified portion" of the OID is the lesser of (i) the amount of OID on the
instrument and (ii) the portion of the total return on such instrument that
bears the same ratio to such total return as the "Excess Yield" bears to the
total yield to maturity on the instrument. The tax treatment to holders will be
unaffected by these provisions except that corporate holders of the Notes may
be treated as receiving distributions with respect to the capital stock of the
Company (rather than interest on such Notes) eligible for the dividends
received deduction, subject to applicable limitations, to the extent of the
"disqualified portion" of the OID and to the extent that such distributions
would have been treated as dividends if actually made by the Company with
respect to its capital stock.

MARKET DISCOUNT

    Holders of the Notes should note that the resale of the 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 a Note (other
than a holder who purchased the 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 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 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 NOTES

    Each holder of Notes generally will recognize gain or loss upon the sale,
exchange, repurchase, redemption, retirement or other disposition of those
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 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 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
Note had been held for more than one year at the time of the sale or exchange.
If the 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 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 basis in a Note will be the
cash price it paid therefor.

<PAGE>   83
BACKUP WITHHOLDING

    A holder of 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 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 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 Note. The term
"Foreign Person" means a nonresident alien individual or foreign corporation,
but only if the income or gain on the Note is not "effectively connected with
the conduct of a trade or business within the U.S." If the income or gain on
the 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 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 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 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 Note on behalf of the owner of the 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 Note is redeemed, retired, sold or exchanged, and certain
other requirements are met.

    Subject to applicable estate tax treaty provisions, Notes held at the time
of death (or 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 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
of Rule 904 under the Securities Act, (iv) to an Institutional Accredited
Investor (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) who has certified to the Company and the Trustee for the Old
Notes that such transferee is an Institutional Accredited Investor and is
acquiring the Old Notes for investment purposes and not for distribution, (v)
pursuant to an exemption from the registration requirements of the Securities
Act provided by Rule 144 (if applicable) under the Securities Act or (vi)
pursuant to an effective registration statement under the Securities Act, in
each case in accordance with any applicable securities laws of any state of the
United States, (B) the purchaser will, and each subsequent holder is required
to, notify any purchaser of the Old Notes from it of the resale restrictions
referred to in (A) above, if then applicable, and (C) with respect to any
transfer of the Old Notes by an Institutional Accredited Investor, such holder
will deliver to the Company and the Trustee such certificates and other
information as they may reasonably require to confirm that the transfer by it
complies with the foregoing restrictions;

    (4) it is understood that the notification requirement referred to in (3)
above will be satisfied, in the case only of transfers by physical delivery of
Certificated Securities other than a Global Note by virtue of the fact that the
following legend will be placed on the Old Notes unless otherwise agreed by the
Company:

    "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS

    (5) it (i) had such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of its prospective
investment in the Old Notes and (ii) had the ability to bear the economic risks
of its prospective investment and can afford the complete loss of such
investment;

    (6) it received a copy of the Offering Memorandum relating to the offering
and acknowledges that it has had access to such financial and other
information, and has been afforded the opportunity to ask questions of the
Company and receive answers thereto, as it deemed necessary in connection with
its decision to purchase the Old Notes; and

    (7) it understood that the Company, the Initial Purchasers and others
relied upon the truth and accuracy of the foregoing acknowledgments,
representations and agreements and agreed that if any of the acknowledgments,
representations and warranties deemed to have been made by it by its purchase
of the Old Notes are no longer accurate, it shall promptly notify the Company

agent for one or more investor accounts, it represented that it had sole
investment discretion with respect to each such account and  had full power to
make the foregoing acknowledgments, representations and agreements on behalf of
such account.

                                 LEGAL MATTERS

exceed production expenses and taxes.

    Exploratory well. A well drilled to find and produce oil or natural gas
reserves not classified as proved, to find a new reservoir in a field
previously found to be productive of oil or natural gas in another reservoir or
to extend a known reservoir.

    Present value. When used with respect to oil and natural gas reserves, the
estimated future gross revenue to be generated from the production of proved
reserves, net of estimated production and future development costs, using
prices and costs in effect as of the date indicated, without giving effect to
nonproperty-related expenses such as general and administrative expenses, debt
service and future income tax expense or to depreciation, depletion and
amortization, discounted using an annual discount rate of 10%.

    Productive well. A well that is found to be capable of producing
hydrocarbons in sufficient quantities such that proceeds from the sale of such
production exceed production expenses and taxes.

    Proved developed reserves. Proved reserves that can be expected to be
recovered from existing wells with existing equipment and operating methods.

    Proved reserves. The estimated quantities of crude oil, natural gas and

relatively major expenditure is required for recompletion.

    PV-10 Value. When used with respect to oil and natural gas reserves, the
estimated future gross revenue to be generated from the production of proved
reserves, net of estimated production and future development costs, using
prices and costs in effect as of the date indicated, without giving effect to

service and future income tax expense or to depreciation, depletion and
amortization, discounted using an annual discount rate of 10%.

    Recompletion. The completion for production of an existing well bore in
another formation from that in which the well has been previously completed.

reservoirs.

    Royalty interest. An interest in an oil and natural gas property entitling
the owner to a share of oil or natural gas production free of costs of
production.

    3-D seismic. Advanced technology method of detecting accumulations of

created by the collection and measurement of the intensity and timing of sound
waves transmitted into the earth as they reflect back to the surface.

    Undeveloped acreage. Lease acreage 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 such acreage contains proved

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.
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 December 31, 1997. 

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.

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. 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 December 31, 1997. 

(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%.

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.

MICHAEL PETROLEUM CORPORATION
NOTES TO FINANCIAL STATEMENTS


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.

NOTES TO FINANCIAL STATEMENTS, CONTINUED


         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.

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.

NOTES TO FINANCIAL STATEMENTS, CONTINUED



         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 its remaining 7.5%
         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
         approximately $90,000, $49,700, and $69,000, respectively.

         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

         Although the Company does not expect to incur significant expenditures
         to address Year 2000 issues, there can be no assurance that this will
         be the case. Additionally, the ability of third parties with whom the
         Company transacts business to adequately address their Year 2000 issues
         is outside the Company's control. There can be no assurance that the
         failure of the Company or such third parties to adequately address
         their respective Year 2000 issues will not have a material adverse
         effect on the Company's business, financial condition and results of
         operations.

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. Management does not expect the
         adoption of SFAS No. 130 to have a material effect on the Company's
         financial position, results of operations or cash flows.

         In June 1997, the FASB also 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 also 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.

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

         The Company executed a commitment letter with Christiania Bank og
         KreditKasse ("Christiania"), under which after closing of the Offering,
         if the restrictions and covenants of the Notes permit, the Company
         intends to enter into a new reducing revolving credit facility (the
         "Credit Facility") which will provide 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 upon
         maturity on the fourth anniversary of the closing date 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%.

         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 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.

         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.

         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.

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
         with generally accepted accounting principles. This financial statement
         may not be representative of future operations.

SUPPLEMENTAL FINANCIAL INFORMATION
SUPPLEMENTAL 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 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:

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.

THE LOBO 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 "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.

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.

changes therein, and proved developed reserves (all within the United States)

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.

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.

Article XII of the Articles of Incorporation of the Company provides as
follows:

                 suit or proceeding, and any inquiry or investigation that
                 could lead to such an action, suit or proceeding.

(b)      The Corporation 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 determined in accordance with paragraph (f)
of this Section 5 that the person:

         (1)     conducted himself in good faith;

         (2)     reasonably believed:

                 (A)      in the case of conduct in his Official Capacity as a
                          Director of the Corporation, that his conduct was in
                          the Corporation's best interests, and

                 (B)      in all other cases, that his conduct was at least not
                          opposed to the Corporation's best interests; and

         (3)     in the case of any criminal Proceeding, had no reasonable
                 cause to believe his conduct was unlawful.

(c)      Except to the extent permitted by paragraph (e) of this Section 5, a
Director may not be indemnified under subsection 5(b) in respect of a
Proceeding:

         (1)     in which the person is found liable on the basis that personal
                 benefit was improperly received by him; or

         (2)     in which the person is found liable to the Corporation.

(d)      The termination of any Proceeding by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent is not, of
itself, determinative that the person did not meet the requirements set forth
in subsection 5(b).  A person shall be deemed to have been found liable in
respect of any claim, issue or matter only after the person shall have been so
adjudged by a court of competent jurisdiction after exhaustion of all appeals
therefrom.

(e)      A person may be indemnified under subsection 5(b) against judgments,
penalties (including excise and similar taxes), fines, settlements and
reasonable Expenses actually incurred by the person in connection with the
Proceeding; but if the person is found liable to the Corporation or is found
liable on the basis that personal benefit was improperly received by the
person, the indemnification (i) is limited to reasonable Expenses actually
incurred by the person in connection with the Proceeding, and (ii) shall not be
made in respect of any proceeding in which the person shall have been found
liable for willful or intentional misconduct in the performance of his duty to
the Corporation.

(f)      No indemnification under subsection 5(b) shall be made by the
Corporation unless authorized in the specific case after a determination has
been made that the Director has met the standard of conduct set forth in
subsection 5(b).  Such determination shall be made:

         (1)     by the Board of Directors by a majority vote of a quorum
                 consisting of directors who at the time of the vote are not
                 named defendants or respondents in the Proceeding;

         (2)     if such quorum cannot be obtained, then by a majority vote of
                 a committee of the Board of Directors, designated to act in
                 the matter by a majority vote of the full Board of Directors
                 (in which vote directors who are named defendants or
                 respondents may participate), which committee shall consist
                 solely of two or more directors who at the time of the vote
                 are not named defendants or respondents in the Proceeding; or

         (3)     by special legal counsel, selected by the Board of Directors
                 or a committee thereof by vote as set forth in clauses (1) or
                 (2) of this subsection 5(f), or, if the requisite quorum of
                 the full Board of Directors cannot be obtained therefor and
                 such a committee cannot be established, by a majority vote of
                 the full Board of Directors (in which vote directors who are
                 named defendants or respondents may participate); or





                                      II-2
<PAGE>   145
         (4)     by the shareholders in a vote that excludes the shares held by
                 directors who are named defendants or respondents in the
                 Proceeding.

(g)      Authorization of indemnification and determination as to
reasonableness of Expenses shall be made in the same manner as the
determination that indemnification is permissible, except that if the
determination that indemnification is permissible is made by special legal
counsel, authorization of indemnification and determination as to
reasonableness of Expenses shall be made in the manner specified in clause (3)
in subsection 5(f) for the selection of such counsel.  A provision contained in
the Articles of Incorporation, the Bylaws, a resolution of shareholders or
directors, or an agreement that makes mandatory the indemnification permitted
under subsection 5(b) shall be deemed to constitute authorization of
indemnification in the manner required by this section even though such
provision may not have been adopted or authorized in the same manner as the
determination that indemnification is permissible.

(h)      A Director who has been wholly successful, on the merits or otherwise,
in the defense of any Proceeding in which he is a party because he is or was a
Director shall be indemnified by the Corporation against reasonable Expenses
incurred by him in connection with the Proceeding.

(i)      If, upon application of a Director, a court of competent jurisdiction
determines, after giving any notice the court considers necessary, that the
Director is fairly and reasonably entitled to indemnification in view of all
the relevant circumstances, whether or not he has met the standard of conduct
set forth in subjection 5(b) or has been found liable in the circumstances
described in subsection 5(c), the court may order such indemnification as the
court determines is proper and equitable.  The court by law is required to
limit indemnification to reasonable Expenses if the Proceeding is brought by or
on behalf of the Corporation or if the Director is found liable to the
Corporation or is found liable on the basis of circumstances described in
subsection 5(c)(1).

(j)      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 Corporation in advance of the final disposition of
such Proceeding and without the determination specified in subsection 5(f) or
the authorization or determination specified in subsection 5(g) after receipt
by the Corporation of a written affirmation by the Director of his good faith
belief that he has met the standard of conduct necessary for indemnification by
the Corporation as authorized in this Section 5, 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 he has not met that standard or if it is
ultimately determined that indemnification of the director against expenses
incurred by him in connection with that proceeding is prohibited by subsection
5(e).  A provision contained in the Articles of Incorporation, these Bylaws, a
resolution of shareholders or directors, or an agreement that makes mandatory
the payment or reimbursement permitted hereunder shall be deemed to constitute
authorization of that payment or reimbursement.  The written undertaking
required above must be an unlimited general obligation of the Director but need
not be secured.  It may be accepted without reference to financial ability to
make repayment.

(k)      The indemnification provided by this Section 5 shall not be 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 Texas
Business Corporation Act, Bylaw, 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, no provision
for the Corporation to indemnify or to advance Expenses to a Director who was,
is or is threatened to be made a named defendant or respondent to a Proceeding,
whether contained in the Articles of Incorporation, these Bylaws, a resolution
of shareholders or directors, an agreement or otherwise (except as contemplated
by subsection (p)), shall be valid unless consistent with this Section 5 or, to
the extent that indemnity hereunder is limited by the Articles of
Incorporation, consistent therewith.

(l)      Nothing contained in this Section 5 shall limit the Corporation's
power to pay or reimburse Expenses incurred by a Director in connection with
his appearance as a witness in a Proceeding at a time when he is not named
defendant or respondent in the Proceeding.

(m)      Unless limited by the Articles of Incorporation of the Corporation,

         (1)     an officer of the Corporation shall be indemnified as and to
                 the same extent provided in subsection (h) and (i) for a
                 Director and shall be entitled to the same extent as a
                 Director to seek indemnification pursuant to the provisions of
                 such subsections; and

         (2)     the Corporation may indemnify and advance Expenses to an
                 officer, employee or agent of the Corporation to the same
                 extent that it may indemnify and advance Expenses to Directors
                 pursuant to this Section 5.





                                      II-3
<PAGE>   146
(n)      The Corporation may indemnify and advance Expenses to persons who are
not or were not officers, employees or agents of the Corporation but who are or
were serving at the request of the Corporation 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 to the same
extent that it may indemnify and advance expenses to Directors under this
Section 5.

(o)      The Corporation may indemnify and advance Expenses to an officer,
employee, agent or person described pursuant to Section 5(n) and who is not a
Director to such further extent, consistent with law, as may be provided by the
Articles of Incorporation of the Corporation, these Bylaws, general or specific
action of the Board of Directors, or contract or as permitted or required by
common law.

(p)      The Corporation may purchase and maintain insurance or another
arrangement on behalf of any person who is or was a director, officer, employee
or agent of the Corporation, or who is or was serving at the request of the
Corporation 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 him
and incurred by him in any such a capacity or arising out of his status as such
a person, whether or not the Corporation would have the power to indemnify him
against such liability under the provisions of the Texas Business Corporation
Act or this Section 5.  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 Corporation would not have the power to indemnify the
person only if including coverage for the additional liability has been
approved by the shareholders of the Corporation.  Without limiting the power of
the Corporation to procure or maintain any kind of insurance or other
arrangement, a Corporation may, for the benefit of persons indemnified by the
Corporation, (1) create a trust fund, (2) establish any form of self-insurance,
(3) secure its indemnity obligation by grant of a security interest or other
lien on the assets of the Corporation, or (4) establish a letter of credit,
guaranty, or surety arrangement.  The insurance or other arrangement may be
procured, maintained, or established within the Corporation 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 Corporation.  In the absence of
fraud, the judgment of the Board of Directors as to the terms and conditions of
the insurance or other arrangement and the identity of the insurer or other
person participating in an arrangement shall be conclusive and the insurance or
arrangement shall not be voidable and shall not subject the directors approving
the insurance or arrangement to liability, on any ground, regardless of whether
directors participating in the approval are beneficiaries of the insurance or
arrangement.

(q)      Any indemnification of, or advance of Expenses to a Director in
accordance with this Section 5 shall 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 Texas Business
Corporation Act, and in any case, within the 12-month period immediately
following the date of the indemnification or advance.

(r)      For purposes of this Section 5, the Corporation shall be deemed to
have requested a Director to serve as the trustee of an employee benefit plan
whenever the performance by him of his duties to the Corporation also imposes
duties on, or otherwise involves services by, him to the plan or participants
or beneficiaries of the plan.  Excise taxes assessed on a Director with respect
to an employee benefit plan pursuant to applicable law shall be deemed "fines".
Action taken or omitted by him with respect to an employee benefit plan in the
performance of his duties for a purpose reasonably believed by him to be in the
interest of the participants and beneficiaries of the plan shall be deemed to
be for a purpose which is not opposed to the best interests of the
Corporation."

         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
Texas Business Corporation Act. In addition, pursuant to the Agreement, 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.

Securities and Exchange Commission or any regulatory authority, granting until

the shareholders.

         Section 2.  Annual Meeting.  An annual meeting of the shareholders

and, in case of a special meeting, the purpose or purposes for which the

sixty (60) days before the date of the meeting, either personally or by mail,
by or at the direction of the President, the Secretary, or the officer or
person calling the meeting, to each shareholder of record entitled to vote at
such meeting.  If mailed, such notice shall be deemed to be delivered when
deposited in the United States mail address to the shareholder at his address
as it appears on the share transfer records of the Corporation, with postage
thereon prepaid.  Any notice required to be given to any shareholder pursuant
to this Section 4 need not be given to the shareholder if (1) notice of two

between those annual meetings, if any, or (2) all (but in no event less than
two) payments (if sent by first class mail) by the Corporation of distributions
with respect to its stock or interest on securities during a 12-month period

transfer records of the Corporation, and have been returned as undeliverable.

the Corporation a written notice setting forth his then current address, the
requirement that notice be given to that person shall be reinstated.

vote of a greater number is required by law, the Articles of Incorporation or
these Bylaws.  The shareholders present at a duly organized meeting may
continue to transact business until adjournment, notwithstanding the subsequent
withdrawal of enough shareholders to leave less than a quorum or the refusal of
any shareholder present in person or by proxy to vote or participate.

         Section 6.  Adjournments of Annual and Special Meetings of
Shareholders.  If the holders of the amount of shares necessary to constitute a
quorum shall fail to attend any meeting of the shareholder sin person or by
proxy, then the holders of a majority of the shares entitled to vote which are
represented in person or by proxy at the meeting may adjourn any such meeting
from time to time without notice, other than by announcement at the meeting of
the time and place at which the meeting will reconvene, until holders of the
amount of shares requisite to constitute a quorum shall be present at the
particular meeting or at any adjournment thereof, in person or by proxy.  The
holders of a majority of the shares entitled to vote and which are represented
in person or by proxy at a meeting may also adjourn any annual or special
meeting of the shareholders from time to time and without notice, other than by
announcement at the meeting of the time and place at which the meeting will
reconvene, until the transaction of any and all business submitted or proposed
to be submitted to such meeting or any adjournment thereof shall have been
completed.  If the adjournment is for more than 60 days, or if after
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each shareholder of record entitled to
vote at such meeting.  At any such adjourned meeting at which a quorum is
present, in person or by proxy, any business may be transacted which might have
been transacted at the meeting as originally notified or called.

the Corporation, or in the event of his absence, failure or refusal to act, a

whatsoever neither the President nor a Vice President of the Corporation acts
or will act as the Chairman of the meeting of





                                     - 3 -
<PAGE>   4
shareholders, then the shareholders present, in person or by proxy, and
entitled to vote thereat may by majority vote appoint a Chairman who shall act
as Chairman of the meeting.

         The Secretary of the Corporation, or in the event of his absence,
failure or refusal to act, an Assistant Secretary, shall act as Secretary of
each meeting of the shareholders.  If for any reason whatsoever neither the
Secretary nor an Assistant Secretary acts or will act as Secretary of the
meeting of shareholders, then the Chairman of the meeting or, if he fails to do
so, the shareholders present, either in person or by proxy, and entitled to
vote thereat may by majority vote appoint any person to act as Secretary of the
meeting and such person shall act as Secretary of the meeting.

         The Chairman of any meeting shall determine the order of business and
the procedure at the meeting, including such regulation of the manner of voting
and the conduct of discussion as seem to him in order.  Unless the Chairman of
the meeting shall otherwise determine, the order of business shall be as
follows:

         (a)     Calling of meeting to order.

         (b)     Election of a Chairman and the appointment of a Secretary, if
                 necessary.

         (c)     Presentation of proof of the due calling of the meeting.

         (d)     Presentation and examination of proxies and determination of a
                 quorum.

         (f)     Reports of officers and committees.

         (g)     The election of directors if an annual meeting, or a meeting
                 called for that purpose.

         (h)     Unfinished business.

         (i)     New business.

         (j)     Adjournment.

         Section 8.  Attendance and Proxies.  Each shareholder entitled to vote
at a shareholders' meeting may attend such meeting and vote in person or may
attend such meeting by proxy, and vote by such proxy.  Proxies of a shareholder
may only be appointed by an instrument in writing executed by the shareholder
or by such shareholder's duly authorized attorney-in-fact and filed with the
Secretary of the Corporation before or at the time of the particular meeting,
and the attendance or the vote at any such meeting of a proxy of any such
shareholder so appointed shall for all purposes be considered as the attendance
or vote in person of such shareholder.  Telegram, telex, cablegram or similar
transmission by the shareholder, or a photographic, photostatic, facsimile, or
similar reproduction of a writing executed by the shareholder, shall be treated
as an execution in writing of the proxy for the purposes of the preceding
sentence.  All proxies shall be received and taken charge of and all ballots
shall be received and canvassed by the Secretary of the meeting who shall
decide all questions touching upon the qualification of voters, the validity of
the proxies, and the acceptance or rejection of votes, unless an inspector or
inspectors shall have been appointed by the Chairman of the





                                     - 4 -
<PAGE>   5
meeting in which event such inspector or inspectors shall decide all such
questions.  No proxy shall be valid after eleven (11) months from the date of
its execution unless otherwise expressly provided in the proxy.  Each proxy
shall be revocable unless expressly provided therein to be irrevocable and
unless otherwise made irrevocable by law.

         Should a proxy designate two or more persons to act as proxies, unless
such instrument shall provide to the contrary, a majority of such persons
present at any meeting at which their powers thereunder are to be exercised
shall have and may exercise all of the powers of voting or given consents
thereby conferred, or if only one be present, then such powers may be exercised
by that one or, if any even number attend and a majority do not agree on any
particular issue, each proxy so attending shall be entitled to exercise such
powers with respect to the percentage of the total shares equal to the
percentage reached by dividing the number one by the total number of proxies
representing such shares.

         Section 9.  Voting of Shares.  At each meeting of the shareholders,
each outstanding share standing in the shareholder's name on the share transfer
records of the Corporation shall be entitled to one (1) vote on each matter
submitted to vote at such meeting, subject, however, to the provisions of
Section 6 of ARTICLE VIII of these Bylaws, and except to the extent that the
Articles of Incorporation provide for more or less than one vote per share or,
if and to the extent permitted by law, limit or deny voting rights to the
holders of the shares of any class or series, or as otherwise provided by law.
Treasury shares, shares of the Corporation's stock owned by another corporation
the majority of the voting stock of which is owned or controlled by the
Corporation, and shares of the Corporation's stock held by a corporation in a
fiduciary capacity shall not be voted, directly or indirectly, at any meeting,
and shall not be counted in determining the total number of outstanding shares
at any given time.

         At each election for directors by the shareholders, every shareholder
entitled to vote at such election shall have the right to vote, in person or by
proxy, the number of shares owned by him for as many person as there are
directors to be elected and for whose election he has a right to vote, or,
unless expressly prohibited by the Articles of Incorporation of the
Corporation, to cumulate his votes by giving one candidate as many votes as the
number of such directors multiplied by his shares shall equal or by
distributing such votes on the same principle among any number of such
candidates. If cumulative voting of shares of capital stock of the Corporation
has not been denied in the Articles of Incorporation, any shareholder thereby
having cumulative voting rights and who intends to cumulate his votes shall
give written notice of such intention to the Secretary of the Corporation on or
before the day preceding the election at which such shareholder intends to
cumulate his votes, and all shareholders may cumulate his votes as provided for
herein.

         Section 10.  Voting of Shares Owned by Another Corporation.  Shares
standing in the name of another corporation, domestic or foreign, on the books
and records of the Corporation and having voting rights may be voted by such
officer, agent or proxy as the bylaws of such other corporation may authorize
or, in the absence of such authorization, as the board of directors of such
other corporation may determine, provided, however, that when any foreign
corporation without a permit to do business in the State of Texas lawfully owns
or may lawfully own or acquire stock in a Texas corporation, it shall not be
unlawful for such foreign corporation to vote such stock and to participate in
the management and control of the business and affairs of such Texas
corporation, as other shareholders, subject to all laws, rules and regulations
governing Texas corporations and especially subject to the provisions of the
antitrust laws of the State of Texas.

         Section 11.  Shares Held by Fiduciaries, Receivers, Pledges.  Shares
held by an administrator, executor, guardian or conservator may be voted by him
so long as such shares forming a part of an estate are in the possession and
form a part of the estate being served by him, either in person or by proxy,
without a





                                     - 5 -
<PAGE>   6
transfer of such shares into his name.  Shares standing in the name of a
trustee may be voted by him, either in person or by proxy, but not trustee
shall be entitled to vote shares held by him unless such shares shall have been
transferred into his name as trustee.  Shares standing in the name of a
receiver may be voted by such receiver, and shares held by or under the control
of a receiver may be voted by such receiver without such shares being
transferred on the books and records of the Corporation in the name of the
pledgee, and thereafter the pledgee shall be entitled to vote the shares so
transferred.

         Section 12.  Decisions at Meetings of Shareholders.  At all meetings
of the shareholders all elections of Directors shall be determined by a
plurality of the votes of the shareholders entitled to vote represented in
person or by proxy, quorum being present, and all other questions, business and
matters, except those of which the manner of deciding is otherwise expressly
governed by the Texas Business Corporation Act or by the Articles of
Incorporation or by these Bylaws, shall be decided by the vote of the holders
of a majority of the votes of the shareholders entitled to vote, represented in
person or by proxy, a quorum being present.  All voting shall be viva voce,
except that upon the determination of the Chairman of the meeting or upon the
demand of any qualified voter or his proxy, voting on any questions, matter or
business at such meeting shall be by ballot.  In the event any business,
question or matter is so voted upon by ballot, then each ballot shall be signed
by the shareholder voting or by his proxy and shall state the number of shares
so voted.

         At any meeting at which a vote is taken by ballots, the Chairman of
the meeting shall appoint one or more inspectors who shall subscribe an oath or
affirmation to execute faithfully the duties of inspector at such meeting with
strict impartiality and according to the best of his ability.  Such inspector
shall receive the ballots, count the votes and make and sign a certificate of
the result thereof.  The Chairman of the meeting may appoint any person to
serve as an inspector, except no candidate for the office of director shall be
appointed as an inspector.

         Section 13.  List of Shareholders.  A complete list of shareholders
entitled to vote at each shareholders' meeting or any adjournment thereof,
arranged in alphabetical order, with the address of and the number of shares
held by each, shall be prepared by the Secretary and kept on file at the
registered office or principal place of business of the Corporation and shall
be subject to inspection by any shareholder at any time during usual business
hours for a period of at least ten (10) days prior to such meeting and shall be
produced and kept open at such meeting and at all times during such meeting

entitled to examine such list or share transfer records or to vote at any
meeting of the shareholders.

         Section 14.  Record Date.  The Board of Directors shall have the power
to close the share transfer records of the Corporation or, in lieu thereof, to

and to fix a record date for any other purpose as provided in Section 6 of
ARTICLE VIII of these Bylaws.

         Section 15.  Action by Written Consent.  Any action required or which
may be taken at any annual or special meeting of the shareholders may be taken
without a meeting without prior notice and without a vote if a consent or
consents in writing, setting forth the action so taken, shall be signed by
those shareholders holding the number of votes necessary to approve the taking
of such action at a meeting at which all shareholders entitled to vote with
respect to the subject matter thereof were present and voting, and such consent
shall have the same force and effect as a vote at a meeting and may be state as
such in any articles or document filed with the Secretary of State of Texas.
No written consent shall be effective to take the action that is the subject of
the consent unless it bears the date of signature of each shareholder who signs

transaction of any business on the ground that the meeting is not lawfully
called or convened.

                                  ARTICLE III

directors or officers, or between the Corporation and any other corporation,
partnership, association, or other organization or entity in which one or more

financial interest, shall be void or voidable solely for such reason, solely
because the director or officer is present at or participates in the meeting of

ratification by the Board of Directors or any committee thereof or the
shareholders; nor shall any director or officer be responsible to, or liable to
account to, the Corporation for any profits realized by or from or through any
such contract or other transaction of the Corporation so authorized, ratified
or approved, by reason of such interest or his being or having been a director
or officer, or both, of the Corporation.  Nothing herein contained shall create
responsibility or liability in or in connection with any such event or present

for on a consolidated basis or on the equity method of accounting) that purport

         Section 4.  Non-Liability of Directors and Officers in Certain Cases.
No director, officer, or member of a committee shall be liable for his acts as
such if he is excused from liability under any present or future provision of
the Texas Business Corporation Act.

         Section 5.  Indemnification of Directors, Officers, Employees and
Agents.

         (a)     As used in this section:

                 (1)      "Corporation" includes any domestic or foreign
         predecessor entity of the Corporation in a merger, consolidation or
         other transaction in which the liabilities of the predecessor are
         transferred to the Corporation by operation of law and in any other
         transaction in which the Corporation assumes the liabilities of the
         predecessor but does not specifically exclude liabilities that are the
         subject matter of this Section 5.

                 (2)      "Director" means any person who is or was a director
         of the corporation and any person, while a director of the
         Corporation, is or was serving at the request of the Corporation 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,
         employee benefit plan or other enterprise.

                 (3)      "Expenses" include court costs and attorneys' fees.

                 (4)      "Official Capacity" means

                          (A)     when used with respect to a Director, the
                 office of director in the Corporation, and

                          (B)     when used with respect to a person other than
                 a Director, the elective or appointive office in the
                 Corporation held by the officer or the employment or agency
                 relationship undertaken by the employee or agent on behalf of
                 the Corporation,

         but neither A nor B above includes service for any other foreign or
         domestic corporation or any partnership, joint venture, sole
         proprietorship, trust, employee benefit plan or other enterprise.

                 (5)      "Proceeding" means any threatened, pending or
         completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative, any appeal in such an action, suit or
         proceeding, and any inquiry or investigation that could lead to such
         an action, suit or proceeding.

         (b)     The Corporation 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 determined in accordance with
paragraph (f) of this Section 5 that the person:

                 (1)      conducted himself in good faith;

                 (2)      reasonably believed:





                                     - 12 -
<PAGE>   13
                          (A)     in the case of conduct in his Official
                 Capacity as a Director of the Corporation, that his conduct
                 was in the Corporation's best interests, and

                          (B)     in all other cases, that his conduct was at
                 least not opposed to the Corporation's best interests; and

                 (3)      in the case of any criminal Proceeding, had no
         reasonable cause to believe his conduct was unlawful.

         (c)     Except to the extent permitted by paragraph (e) of this
Section 5, a Director may not be indemnified under subsection 5(b) in respect
of a Proceeding:

                 (1)      in which the person is found liable on the basis that
         personal benefit was improperly received by him; or

                 (2)      in which the person is found liable to the
         Corporation.

         (d)     The termination of any Proceeding by judgment, order,
settlement or conviction, or upon a plea of nolo contendere or its equivalent
is not, of itself, determinative that the person did not meet the requirements
set forth in subsection 5(b).  A person shall be deemed to have been found
liable in respect of any claim, issue or matter only after the person shall
have been so adjudged by a court of competent jurisdiction after exhaustion of
all appeals therefrom.

         (e)     A person may be indemnified under subsection 5(b) against
judgments, penalties (including excise and similar taxes), fines, settlements
and reasonable Expenses actually incurred by the person in connection with the
Proceeding; but if the person is found liable to the Corporation or is found
liable on the basis that personal benefit was improperly received by the
person, the indemnification (i) is limited to reasonable Expenses actually
incurred by the person in connection with the Proceeding, and (2) shall not be
made in respect of any proceeding in which the person shall have been found
liable for willful or intentional misconduct in the performance of his duty to
the Corporation.

         (f)     No indemnification under subsection 5(b) shall be made by the
Corporation unless authorized in the specific case after a determination has
been made that the Director has met the standard of conduct set forth in
subsection 5(b).  Such determination shall be made:

                 (1)      by the Board of Directors by a majority vote of a
         quorum consisting of directors who at the time of the vote are not
         named defendants or respondents in the Proceeding;

                 (2)      if such quorum cannot be obtained, then by a majority
         vote of a committee of the Board of Directors, designated to act in
         the matter by a majority vote of the full Board of Directors (in which
         vote directors who are named defendants or respondents may
         participate), which committee shall consist solely of two or more
         directors who at the time of the vote are not named defendants or
         respondents in the Proceeding; or

                 (3)      by special legal counsel, selected by the Board of
         Directors or a committee thereof by vote as set forth in clauses (1)
         or (2) of this subsection 5(f) or, if the requisite quorum of the full
         Board of Directors cannot be obtained therefor and such a committee
         cannot be established, by a





                                     - 13 -
<PAGE>   14
         majority vote of the full Board of Directors (in which vote directors
         who are named defendants or respondents may participate); or

                 (4)      by the shareholders in a vote that excludes the
         shares held by directors who are named defendants or respondents in
         the Proceeding.

         (g)     Authorization of indemnification and determination as to
reasonableness of Expenses shall be made in the same manner as the
determination that indemnification is permissible, except that if the
determination that indemnification is permissible is made by special legal
counsel, authorization of indemnification and determination as to
reasonableness of Expenses shall be made in the manner specified in clause (3)
in subsection 5(f) for the selection of such counsel.  A provision contained in
the Articles of Incorporation, the Bylaws, a resolution of shareholders or
directors, or an agreement that makes mandatory the indemnification permitted
under subsection 5(b) shall be deemed to constitute authorization of
indemnification in the manner required by this section even though such
provision may not have been adopted or authorized in the same manner as the
determination that indemnification is permissible.

         (h)     A Director who has been wholly successful, on the merits or
otherwise, in the  defense of any Proceeding in which he is a party because he
is or was a Director shall be indemnified by the Corporation against reasonable
Expenses incurred by him in connection with the Proceeding.

         (i)     If, upon application of a Director, a court of competent
jurisdiction determines, after giving any notice the court considers necessary,
that the Director is fairly and reasonably entitled to indemnification in view
of all the relevant circumstances, whether or not he has met the standard of
conduct set forth in subsection 5(b) or has been found liable in the
circumstances described in subsection 5(c), the court may order such
indemnification as the court determines is proper and equitable.  The court by
law is required to limit indemnification to reasonable Expenses if the
Proceeding is brought by or on behalf of the Corporation or if the Director is
found liable to the Corporation or is found liable on the basis of
circumstances described in subsection 5(c)(1).

         (j)     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 Corporation in advance of the final disposition of
such Proceeding and without the determination specified in subsection 5(f) or
the authorization or determination specified in subsection 5(g) after receipt
by the Corporation of a written affirmation by the Director of his good faith
belief that he has met the standard of conduct necessary for indemnification by
the Corporation as authorized in this Section 5, 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 he has not met that standard or if it is
ultimately determined that indemnification of the director against expenses
incurred by him in connection with that proceeding is prohibited by subsection
5(e).  A provision contained in the Articles of Incorporation, these Bylaws, a
resolution of shareholders or directors, or an agreement that makes mandatory
the payment or reimbursement permitted hereunder shall be deemed to constitute
authorization of that payment or reimbursement.  The written undertaking
required above must be an unlimited general obligation of the Director but need
not be secured.  It may be accepted without reference to financial ability to
make repayment.

         (k)     The indemnification provided by this Section 5 shall not be
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 Texas
Business Corporation Act, Bylaw, 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





                                     - 14 -
<PAGE>   15
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, no provision for the Corporation to indemnify or to advance Expenses
to a Director who was, is or is threatened to be made a named defendant or
respondent to a Proceeding, whether contained in the Articles of Incorporation,
these Bylaws, a resolution of shareholders or directors, an agreement or
otherwise (except as contemplated by subsection(p)), shall be valid unless
consistent with this Section 5 or, to the extent that indemnity hereunder is
limited by the Articles of Incorporation, consistent therewith.

         (l)     Nothing contained in this Section 5 shall limit the
Corporation's power to pay or reimburse Expenses incurred by a Director in
connection with his appearance as a witness in a Proceeding at a time when he
is not a named defendant or respondent in the Proceeding.

         (m)     Unless limited by the Articles of Incorporation of the
Corporation,

                 (1)      an officer of the Corporation shall be indemnified as
         and to the same extent provided in subsection (h) and (I) for a
         Director and shall be entitled to the same extent as a Director to
         seek indemnification pursuant to the provisions of such subsections;
         and

                 (2)      the Corporation may indemnify and advance Expenses to
         an officer, employee or agent of the Corporation to the same extent
         that it may indemnify and advance Expenses to Directors pursuant to
         this Section 5.

         (n)     The Corporation may indemnify and advance Expenses to person
who are not or were not officers, employees, or agents of the Corporation but
who are or were serving at the request of the Corporation 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
to the same extent that it may indemnify and advance expenses to Directors
under this Section 5.

         (o)     The Corporation may indemnify and advance Expenses to an
officer, employee, agent or person described pursuant to Section 5(n) and who
is not a Director to such further extent, consistent with law, as may be
provided by the Articles of Incorporation of the Corporation, these Bylaws,
general or specific action of the Board of Directors, or contract or as
permitted or required by common law.

         (p)     The Corporation may purchase and maintain insurance or another
arrangement on behalf of any person who is or was a director, officer, employee
or agent of the Corporation, or who is or was serving at the request of the
Corporation 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 him
and incurred by him in any such a capacity or arising out of his status as such
a person, whether or not the Corporation would have the power to indemnify him
against such liability under the provisions of the Texas Business Corporation
Act or this Section 5.  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 Corporation would not have the power to indemnify the
person only if including coverage for the additional liability has been
approved by the shareholders of the Corporation.  Without limiting the power of
the Corporation to procure or maintain any kind of insurance or other
arrangement, a Corporation may, for the benefit of persons indemnified by the
Corporation, (1) create a trust fund, (2) establish any form of self-insurance,
(3) secure its indemnity





                                     - 15 -
<PAGE>   16
obligation by grant of a security interest or other lien on the assets of the
Corporation, or (4) establish a letter of credit, guaranty, or surety
arrangement.  The insurance or other arrangement may be procured, maintained,
or established within the Corporation 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 owned in whole
or in part by the Corporation.  In the absence of fraud, the judgment of the
Board of Directors as to the terms and conditions of the insurance or other
arrangement and the identity of the insurer or other person deemed
participating in an arrangement shall be conclusive and the insurance or
arrangement shall not be voidable and shall not subject the directors approving
the insurance or arrangement to liability, on any ground, regardless of whether
directors participating in the approval are beneficiaries of the insurance or
arrangement.

         (q)     Any indemnification of, or advance of Expenses to a Director
in accordance with this Section 5 shall 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 Texas Business Corporation Act, and in any case, within the 12-month period
immediately following the date of the indemnification or advance.

         (r)     For purposes of this Section 5, the Corporation shall be
deemed to have requested a Director to serve as the trustee of an employee
benefit plan whenever the performance by him of his duties to the Corporation
also imposes duties on, or otherwise involves services by, him to the plan or
participants or beneficiaries of the plan.  Excise taxes assessed on a Director
with respect to an employee benefit plan pursuant to applicable law shall be
deemed "fines".  Action taken or omitted by him with respect to an employee
benefit plan in the performance of his duties for a purpose reasonably believed
by him to be in the interest of the participants and beneficiaries of the plan
shall be deemed to be for a purpose which is not opposed to the best interests
of the Corporation.

\and, unless the resolution establishing the committee or the Articles of
Incorporation expressly so provide, no such committee shall have the power and
authority to authorize any distribution by the Corporation to any of the

the members of any such committee may determine its action and fix the time and
place of its meetings, unless the Board of Directors shall otherwise provide.
At every meeting of any such committee, the presence of a majority of all of
the members thereof shall constitute a quorum and the affirmative vote of a
majority F.O. the members present shall be necessary for the adoption by it of
any resolution.  The Board of Directors shall have power at any time to change

discharge any such committee.  The Board of Directors may designate one or more
directors as alternate members of any committee, who may, subject to any
limitation imposed by the Board of Directors, replace any absent or
disqualified member of the committee at any meeting of such committee.  In the
absence or disqualification of a member of a committee, the member or members
present at any meeting and not disqualified from voting, whether or not
constituting a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of the absent or disqualified
member.  The designation of such committee and the delegation thereto of
authority shall not operate to relieve the Board of Directors, or any member
thereof, of any responsibility imposed by law.

                                  ARTICLE VIII

                                 CAPITAL STOCK

         Section 1.  Stock Certificates.  The certificates for shares of the
capital stock of the Corporation shall be in such form, not inconsistent with
that required by law and the Articles of Incorporation, as shall be approved by
the Board of Directors.  They shall be consecutively numbered and shall be
entered in the books of the Corporation as they are issued and shall exhibit
the holder's name and number of shares.  Every holder of stock in the
Corporation shall be entitled to have a certificate signed by, or in the name
of, the Corporation by the President or a Vice President and either the
Secretary or an Assistant Secretary of the Corporation, certifying the number
of shares (and, if the stock of the Corporation shall be divided into classes
or series, the class and series of such shares) owned by him in the
Corporation, with the seal of the Corporation or a facsimile thereof impressed
or printed thereon.  Where any such certificate is countersigned by a transfer
agent or registered by a registrar, either of which is another than the
Corporation itself or an employee of the Corporation, the signatures of the
President or Vice President and the Secretary or Assistant Secretary upon a
certificate may be facsimiles, engraved or printed.  In case any officer who
shall have signed or whose facsimile signature shall have been placed on any
such certificate shall have ceased to be such officer of the Corporation,
whether because of death, resignation or otherwise, before such certificate is
issued, such certificate may nevertheless be issued and delivered by the
Corporation with the same effect as if the person were such officer at the date
of its issuance.

         Section 2.  Transfers.  Stock of the Corporation shall be transferable
in the manner prescribed by the laws of the State of Texas and in these Bylaws.
Transfers of stock shall be made on the books of the Corporation only by the
person named in the certificate, or by his attorney-in-fact or legal
representative, duly and lawfully authorized in writing, and upon the surrender
of the certificate therefor, which shall be cancelled before the new
certificate for a like number of shares shall be issued.  Upon surrender to the
Corporation or a transfer agent of the Corporation of a certificate for shares
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, it shall be the duty of the Corporation to issue a new
certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

         The Board of Directors may appoint a transfer agent or a registrar for
each class of stock, and may require all stock certificates to bear the
signature of such transfer agent and of such registrar or either of them.  The
stock record books and the blank stock certificate books shall be kept by the
Secretary, or at the office of such transfer agent or transfer agents as the
Board of Directors may from time to time by resolution determine.

         Section 3.  Registered Holders.  The Corporation shall be entitled to
treat the person in whose name any share of stock or any warrant, right or
option is registered as the owner thereof for all purposes and shall not be
bound to recognize any equitable or other claim to, or interest in, such share,
warrant, right or option on the part of any other person, whether or not the
Corporation shall have notice thereof, save as may be expressly provided
otherwise by the laws of the State of Texas.

         Section 4.  New Certificates.  The Corporation may, in its sole
discretion, issue a new certificate for shares of its stock in the place of any
certificate theretofore issued by it, alleged to have been lost or destroyed
certificate, or his legal representative, to give the Corporation such
statement under oath or other evidence of such loss or destruction as the Board
may desire, and a bond in form, amount and with such surety as the Board of
Directors may prescribe or determine, and sufficient, in the sole judgment of
the Board, to indemnify and protect the Corporation against any and all claims,
liabilities, costs and expenses that may be made or asserted against it or
which it may suffer or incur or pay, on account of the alleged loss





                                     - 20 -
<PAGE>   21
of any such certificate or the issuance of such new certificate.  A new
certificate may be issued without requiring any bond when, in the sole
discretion of the Board, it is proper so to do.

         Section 5.  Distributions.  The Board of Directors may declare
distributions of the assets of the Corporation to its shareholders as the Board
deems expedient and as permitted by law under the provisions of the Texas
Business Corporation Act.  Before declaring any distributions there may be
reserved out of the earned surplus such sums as the Board of Directors deems
proper for working capital or as a reserve fund to meet contingencies or for
equalizing distributions, or for such other purposes as the Board may deem
conducive to the interests of the Corporation, and the Board may abolish any
such reserve in the manner in which it was created.

         Section 6.  Record Dates and Closing of Share Transfer Records.  For
the purpose of determining shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or entitled to receive a
distribution by the Corporation (other than a distribution involving a purchase
or redemption by the Corporation of any of its own shares) or a share dividend,
or in order to make a determination of shareholders for any other proper
purpose (other than determining shareholders entitled to consent to action by
shareholders proposed to be taken without a meeting of shareholders), the Board
of Directors of the Corporation may provide that the share transfer records
shall be closed for the purpose of determining shareholders entitled to notice
of or to vote at a meeting of shareholders, such books shall be closed for at
least ten (10) days immediately preceding such meeting.  In lieu of closing the
share transfer records, the Board of Directors may fix in advance a date as the
record date for any such determination of shareholders, such date in any case
to be not more than sixty (60) days and, in case of a meeting of shareholders,
not less than ten (10) days prior to the date on which the particular action
requiring such determination of shareholders is to be taken.  If the share
transfer records are not closed and no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting of
shareholders, or shareholders entitled to receive payment of a distribution,
the date on which the notice of the meeting is mailed or the date on which the
resolution of the Board of Directors declaring such distribution is adopted, as
the case may be, shall be the record date for such determination of
shareholders.  When a determination of shareholders entitled to vote at any
meeting of shareholders has been made as provided herein, such determination
shall apply to any adjournment thereof except where the determination has been
made through the closing of share transfer records and the stated period of
closing has expired.

         Unless a record date shall have previously been fixed or determined
pursuant to this Section 6, whenever action by shareholders is proposed to be
taken by consent in writing without a meeting of shareholders, the Board of
Directors may fix a record date for the purpose of determining shareholders
entitled to consent to that action, which record date shall not precede, and
shall not be more than ten (10) days after, the date upon which the resolution
fixing the record date is adopted by the Board of Directors.  If no record date
has been fixed by the Board of Directors and the prior action of the Board of
Directors is not required by the Texas Business Corporation Act, the record
date for determining shareholders entitled to consent to action in writing
without a meeting shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
Corporation by delivery to its registered office, its principal place of
business, or the Secretary or an Assistant Secretary of the Corporation.
Delivery shall be by hand or by certified or registered mail, return receipt
requested.  Delivery to the Corporation's principal place of business shall be
addressed to the President or the Chief Executive Officer of the Corporation.
If no record date shall have been fixed by the Board of Directors and prior
action of the Board of Directors is required by the Texas Business Corporation
Act, the record date for determining shareholders entitled to consent to action
in writing without a meeting shall be at the close of business on the date on
which the Board of Directors adopts a resolution taking such prior action.

<PAGE>   22
         Section 7.  Regulations.  The Board of Directors shall have power and
authority to make all such rules and regulations as they may deem expedient
concerning the issue, transfer and registration or the replacement of
certificates for shares of the capital stock of the Corporation.

manner affixed.  The Secretary shall have charge of the seal.  If and when so
directed by the Board of Directors, duplicates of the seal may be kept and used

         Section 3.  Notice and Waiver of Notice.  Whenever any notice is
required to be given under the provisions of the Texas Business Corporation Act

Corporation, said notice shall be deemed to be sufficient if given by
depositing the same in a post office box in a sealed post-paid wrapper
addressed to the person entitled thereto at his post office address as the same
appears on the books or other records of the Corporation, and such notice shall
be deemed to have been given and received if given in any other manner or by
any other means authorized or provided for elsewhere in these Bylaws.  A

time.  Each such resignation shall be made in writing and shall take effect at
the time specified therein, or, if no time be specified, at the time of its

all notes and other evidences of indebtedness of the Corporation shall be

person as shall be determined or designated by the Board of Directors;
provided, however, that if, when, after and as authorized or provided for by
the Board of Directors, the signature of any such officer or person may be a
facsimile or engraved or printed, and shall have the same force and effect and
bind the Corporation as though such officer or person had signed the same
personally, and, in the event of the death, disability, removal or resignation
of any such officer or person, if the Board of Directors





                                     - 22 -
<PAGE>   23
shall so determine or provide, as though and with the same effect as if such
death, disability, removal or resignation had not occurred.

         Section 7.  Gender and Number.  Wherever used or appearing in these
Bylaws, pronouns of the masculine gender shall include the persons of the
female sex as well as the neuter gender and the singular shall include the
plural wherever appropriate.

         Section 8.  Laws and Statutes.  Wherever used or appearing in these
Bylaws, the words "law" or "laws" or "statute" or "statutes," respectively,

         Section 9.  Headings.  The headings of the Articles and Sections of
these Bylaws are inserted for convenience of reference only and shall not be
deemed to be a part thereof or used in the construction or interpretation
thereof.

information is given in the Definitive Memorandum, except as set forth in the
Definitive Memorandum, there has not been any material adverse change in the
business, prospects, properties, operations, condition (financial or other) or
results of operations of the Company and MHI, taken as a whole, whether or not
arising from transactions in the ordinary course of business, and since the
date of the latest balance sheet included in the Definitive Memorandum, neither
the Company nor MHI has incurred or undertaken any liabilities or obligations,
direct or contingent, that are material to the Company and MHI taken as a
whole, except for liabilities or obligations that were incurred or undertaken
in the ordinary course of business or that are fully reflected or disclosed in
the Definitive Memorandum.

                 c.       Each of the Company and MHI has all requisite
corporate power and authority to execute, deliver and perform its obligations
under this Agreement and to consummate the transactions contemplated hereby,
including, without limitation, the corporate power and authority to issue, sell
and deliver the Notes as provided herein.  The Company has all requisite
corporate power and authority to execute, deliver and perform its obligations
under the Registration Rights Agreement,

<PAGE>   3
the Indenture and the Notes and to consummate the transactions contemplated
thereby.

                 d.       This Agreement and the Registration Rights Agreement
have been duly and validly authorized, executed and delivered by the Company
and each is a valid and binding agreement of the Company enforceable against it
in accordance with its terms, except insofar as (i) such enforcement may be

reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (B) general principles of equity
(regardless of whether enforcement is sought in a proceeding at law or in
equity) and (ii) rights to indemnification and contribution may be limited by
federal or state securities laws or public policy relating thereto.  This
Agreement has been duly and validly authorized, executed and delivered by MHI
and is a valid and binding agreement of MHI enforceable against it in

federal or state securities laws or public policy relating thereto.  This
Agreement and the Registration Rights Agreement conform in all material
respects to the descriptions thereof contained in the Offering Memorandum.

                 e.       The execution, delivery and performance of this
Agreement, the Registration Rights Agreement, the Indenture and the Notes and
the consummation of the transactions contemplated hereby and thereby, including
the issuance, sale and delivery of the Notes and application of the proceeds of
the sale thereof as set forth in the Offering Memorandum, will not (i) conflict
with or result in a breach of any of the terms and provisions of, or constitute
a default (or an event that with notice or lapse of time, or both, would
constitute a default) or require consent under, or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of
the Company or MHI pursuant to, the terms of any agreement, instrument,
franchise, license or permit to or by which the Company or MHI is a party or
may be bound (other than those as to which requisite waivers or consents have
been obtained by the Company or MHI), or (ii) violate or conflict with any
provision of the articles of incorporation, by-laws or equivalent instruments
of the Company or MHI or any judgment, decree, order, statute, rule or
regulation of any court or any public, governmental or regulatory agency or
body having jurisdiction over the Company or MHI or any of their respective
properties or assets.  No consent, approval, authorization, order,
registration, filing, qualification, license or permit of or with any court or
any public, governmental or regulatory agency or body having jurisdiction over
the Company or MHI or any of their respective properties or assets is required,
which has not been obtained, for the execution, delivery and performance of

                                      -3-

or the consummation of the transactions contemplated hereby and thereby except
as may be required for compliance with federal and state securities laws in
connection with the purchase of the Notes by the Initial Purchasers and
performance of the Company's obligations under the Registration Rights
Agreement.

                 f.       Each of the Company and MHI has been duly formed, is
validly existing as a corporation in good standing under the laws of the State
of Texas and has the corporate power and authority required to carry on its
business as described in the Offering Memorandum and to own, lease and operate
its properties, and each is duly qualified and is in good standing as a foreign
corporation authorized to transact business in each jurisdiction in which the
nature of its business or its ownership or leasing of property requires such
qualification, except where the failure to be so qualified would not (i)
result, individually or in the aggregate, in a material adverse effect on the
business, prospects, financial condition or results of operations of the
Company and MHI, taken as a whole, (ii) interfere with or adversely affect the
issuance or marketability of the Notes pursuant hereto or (iii) in any manner
draw into question the validity of this Agreement, the Registration Rights
Agreement, the Indenture or the Notes or the transactions described in the
Offering Memorandum under the caption "Use of Proceeds" (any of the events set
forth in clauses (i), (ii) or (iii), a "Material Adverse Effect").

                 g.       All of the outstanding shares of capital stock of the

non-assessable, and are owned by MHI, free and clear of any security interest,
claim, lien or encumbrance, except for security interests relating to the
T.E.P. Financing.  All of the outstanding shares of capital stock of MHI have
been duly and validly authorized and issued and are fully paid and

Amended and Restated Shareholders Agreement dated December 4, 1996, by and
among MHI and its shareholders.  On the Closing Date, there will not be any
rights granted to or in favor of any person to acquire, at present or in the
future, any such capital stock or other equity interests of the Company or MHI,
except as disclosed in the Offering Memorandum.  The Company has no
subsidiaries, and MHI has no subsidiaries other than the Company.

                 h.       The authorized, issued and outstanding capital stock
of the Company, as of December 31, 1997, was (i) 100,000,000 shares of common
stock, par value $.10 per share, authorized ("Common Stock"), of which 10,000
shares are issued and outstanding and (ii) 50,000,000 shares of preferred
stock, par value $.10 per share, authorized (the "Preferred Stock"), of which

the Company have been authorized or issued since December 31, 1997.  As of the
Closing Date, all of the outstanding shares of Common Stock will have been duly
authorized and validly





                                      -4-

issued, fully paid and non-assessable and will not have been issued in

as disclosed in the Offering Memorandum, (i) there will be no outstanding
securities of the Company convertible into or evidencing the right to purchase
or subscribe for any shares of capital stock of the Company; (ii) there will be
no outstanding or authorized options, warrants, calls, subscriptions, rights,
commitments or any other agreements of any character obligating the Company to

(iii) there will be no agreements with respect to the voting, sale or transfer
of any shares of capital stock of the Company to which the Company is a party.

                 i.       The authorized, issued and outstanding capital stock

as disclosed in the Offering Memorandum, (i) there will be no outstanding
securities of MHI convertible into or evidencing the right to purchase or

(iii) there will be no agreements with respect to the voting, sale or transfer
of any shares of capital stock of MHI to which MHI is a party.

                 j.       The Notes have been duly and validly authorized by
all necessary corporate action and, when authenticated by the Trustee and
issued, sold and delivered by the Company pursuant to this Agreement against
payment therefor, will have been duly and validly executed, authenticated,
issued and delivered and will constitute valid and binding obligations of the
Company entitled to the benefits of the Indenture and enforceable against the
Company in accordance with their terms, except insofar as such enforcement may
be subject to (i) applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (ii) general principles of equity
(regardless of whether enforcement is sought in a proceeding at law or in
equity).  The Notes, when issued, will conform in all material respects to the
description thereof set forth in the Offering Memorandum.





                                      -5-
<PAGE>   6
                 k.       The Indenture conforms in all material respects to
the description thereof set forth in the Offering Memorandum, conforms in all
material respects with the requirements of the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"), applicable to indentures to be qualified
thereunder, has been duly and validly authorized by all necessary corporate
action and, when executed and delivered by the Company and the Trustee, will
constitute a valid and binding agreement of the Company enforceable against the
Company in accordance with its terms, except insofar as such enforcement may be
subject to (i) applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (ii) general principles of equity
(regardless of whether enforcement is sought in a proceeding at law or in
equity).

                 l.       Neither MHI nor the Company is (i) in violation of
its charter or by-laws or other governing instrument, (ii) in default in the
performance of any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or in any other
agreement, indenture or instrument to which it is a party or by which it or any
of its property is bound, except for those defaults that, individually or in
the aggregate, would not have a Material Adverse Effect, or (iii) in violation
of any local, state, federal or foreign law, statute, ordinance, rule,
regulation, requirement, judgment or court decree (including, without
limitation, environmental laws, statutes, ordinances, rules, regulations,
judgment or court decrees) applicable to it or any of its assets or properties
(whether owned or leased), except for violations that, individually or in the
aggregate, would not have a Material Adverse Effect.  To the best knowledge of
the Company and MHI, there exists no condition that, with notice, the passage
of time or otherwise, would constitute a violation of its charter or bylaws or
other governing instrument, or a default under any bond, debenture, note or any
other evidence of indebtedness or in any other agreement, indenture or
instrument to which it is a party or by which it or any of its property is
bound, except for those defaults that, individually or in the aggregate, would
not have a Material Adverse Effect.

                 m.       There is (i) no action, suit, investigation or
proceeding before or by any court, arbitrator or governmental agency, body or
official, domestic or foreign, now pending or, to the best knowledge of the
Company and MHI, threatened to which the Company or MHI is or may be a party or
to which any of their respective properties or assets is subject, (ii) no
statute, rule, regulation or order that has been enacted, adopted or issued by
any governmental agency or, to the best knowledge of the Company and MHI, that
has been proposed by any governmental body and (iii) no injunction, restraining
order or order of any nature by a federal or state court or foreign court of
competent jurisdiction to which the Company or MHI is or may be subject or to
which the properties or assets of the Company or MHI is or may be subject,
that, in the case of clauses (i), (ii) and (iii) above, (x) is required to be
disclosed in the Offering Memorandum and is not so disclosed or (y) could
reasonably





                                      -6-
<PAGE>   7
be expected to have a Material Adverse Effect.  There is no contract or
document material to the Company and MHI, taken as a whole, that would be
required to be described in the Offering Memorandum if it were a prospectus
included in a registration statement on Form S-3 under the Securities Act that
is not so described.

                 n.       Each of the Company and MHI has and, after giving
effect to the Transactions, will have all necessary licenses, consents,
authorizations, approvals, orders, certificates and permits (collectively,
"Licenses") of and from, and has made all declarations and filings with and
satisfied all eligibility and other similar requirements imposed by all
federal, state, local and other governmental authorities, all self-regulatory
organizations and all courts and other tribunals, in each case as required for
the conduct of the business in which it is engaged, and each such License is in
full force and effect, except to the extent that the failure to obtain any such
License or to make any such declaration or filing or satisfy any such
requirement would not have a Material Adverse Effect.  Neither the Company nor
MHI has received any notice of proceedings relating to, or has any reason to
believe that any governmental body or agency is considering limiting,
suspending, modifying or revoking, any such License that would have a Material
Adverse Effect.

                 o.       Coopers & Lybrand L.L.P., whose reports are included
in the Offering Memorandum, is an independent public accountant (as defined in
the Securities Act) with respect to the Company and MHI.

                 p.       The consolidated financial statements of MHI and
respective notes thereto included in the Offering Memorandum present fairly in
all material respects the consolidated financial position, results of
operations, cash flows and stockholders' deficit of MHI (as reflected in such
financial statements) in conformity with generally accepted accounting
principles on the basis stated therein at the respective dates or for the
respective periods to which they apply; the statements of revenues and direct
operating expenses and respective notes thereto related to the Lobo Properties
and the properties to be acquired pursuant to each of the Conoco Acquisition
and the Enron Acquisition present fairly in all material respects the revenues
and direct operating expenses of the properties to which they relate in
conformity with generally accepted accounting principles on the basis stated
therein at the respective dates or for the respective periods to which they
apply; all of such statements and notes have been prepared in accordance with
generally accepted accounting principles consistently applied throughout the
periods involved, except as disclosed therein; and the other financial and
statistical information and data set forth in the Offering Memorandum, in all
material respects, present fairly the information purported to be shown thereby
at the respective dates or for the respective periods to which they apply and
have been prepared on a basis consistent with such financial statements and the
books and records of the Company and the other entities as to which such
information is shown.  The pro forma financial statements of MHI included in
the Definitive Memorandum have been prepared in accordance with the published
rules





                                      -7-
<PAGE>   8
and regulations of the Commission applicable to pro forma financial statements
(except for earnings per share information, which has been omitted from such
pro forma financial statements) and the assumptions used in the preparation
thereof are reasonable and appropriate to give pro forma effect in all material
respects to the transactions or circumstances described therein.

                 q.       On December 31, 1997, after giving pro forma effect
to the issuance and sale of the Notes pursuant hereto, the application of the
net proceeds therefrom and the Transactions, the Company would have had an
authorized and outstanding capitalization as set forth in the Offering
Memorandum under "Capitalization."

                 r.       The Company is not an "investment company" or a
company "controlled" by an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

                 s.       Neither the Company nor any person acting on its
behalf (provided that no representation is made as to the Initial Purchasers or
any other person acting on their behalf) has offered the Notes for sale by
means of any general solicitation or general advertising within the meaning of
Rule 502(c) under the Securities Act.  Neither the Company nor any of its
affiliates has offered the Notes to any person except through the Initial
Purchasers.  Neither the Company nor any person acting on its behalf (provided
that no representation is made as to the Initial Purchasers or any other person
acting on their behalf) has offered the Notes or any similar securities for
sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, any person other than the
Initial Purchasers and not more than 35 other institutional investors.  Neither
the Company nor any affiliate (as defined in Rule 501(b) under the Securities
Act) thereof has, directly or indirectly, or through any agent, within the six
months preceding the date hereof, sold, offered for sale, solicited offers to
buy or otherwise negotiated in respect of the sale of any security of the same
or a similar class as the Notes other than to the Initial Purchasers pursuant
to this Agreement.

                 t.       Since the date of the Preliminary Memorandum, none of
the Company, MHI or any of their affiliates has (i) sold, bid or, purchased or
paid any person any compensation for soliciting purchases of the Notes or (ii)
paid or agreed to pay to any person any compensation for soliciting another to
purchase any other securities of the Company or MHI, other than to the Initial
Purchasers pursuant to this Agreement.

                 u.       Assuming the accuracy of the Initial Purchasers'
representations contained in Section 3 hereof and the Initial Purchasers'
compliance with their covenants therein set forth, it is not necessary, in
connection with the sale and delivery of the Notes to the Initial Purchasers
and the offer and resale of the Notes





                                      -8-
<PAGE>   9
by the Initial Purchasers, in each case in the manner contemplated by this
Agreement and the Offering Memorandum, to register the Notes under the
Securities Act or to qualify the Indenture under the Trust Indenture Act.

                 v.       Neither the Company nor MHI (i) has violated any
environmental, safety, health or similar law or regulation applicable to its
business relating to the protection of human health and safety, the environment
or hazardous or toxic substances or wastes, pollutants or contaminants,
including, without limitation, the Clean Air Act, as amended, the Clean Water
Act, as amended, the Comprehensive Environmental Response, Compensation and
Liability Act, as amended, the Federal Water Pollution Control Act, as amended,
the Resource Conservation and Recovery Act, as amended, the Toxic Substances
Control Act, as amended, the Oil Pollution Act, as amended, the Occupational
Safety and Health Act, as amended, and comparable state and local laws and
other safety, health and environmental conservation or protection laws
("Environmental Laws"), the effect of which would be to cause, individually or
in the aggregate, a Material Adverse Effect, or (ii) lacks any notices,
permits, licenses or other approvals required of them under applicable
Environmental Laws or is violating any terms and conditions of any such notice,
permit, license or approval, the effect of which would be to cause,
individually or in the aggregate, a Material Adverse Effect.  Without
limitation of the foregoing, there is as of the date hereof no litigation or
action pending or, to the best knowledge of the Company and MHI, threatened
against the Company or MHI relating to any violation of any Environmental Laws
with respect to the assets or business of the Company or MHI which is required
to be disclosed in the Offering Memorandum, or which might result, individually
or in the aggregate, in a Material Adverse Effect.


                 w.       There is no alleged liability, or to the best
knowledge of the Company and MHI, potential liability (including, without
limitation, alleged or potential liability or investigatory costs, cleanup
costs, governmental response costs, natural resource damages, property damages,
personal injuries or penalties) of the Company or MHI arising out of, based on
or resulting from (i) the presence or release into the environment of any
Hazardous Material (as defined) at any location leased or owned by the Company
or MHI or (ii) any violation or alleged violation of any Environmental Law,
which alleged or potential liability is required to be disclosed in the
Offering Memorandum, other than as disclosed therein, or could reasonably by
expected to have a Material Adverse Effect.  The term "Hazardous Material"
means (i) any "hazardous substance" as defined by the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended,
(ii) any "hazardous waste"; as defined by the Resource Conservation and
Recovery Act, as amended, (iii) any petroleum or petroleum product, (iv) any
polychlorinated biphenyl and (v) any pollutant or contaminant or hazardous,
dangerous or toxic chemical, material, waste or substance regulated under or
within the meaning of any other law relating to the





                                      -9-
<PAGE>   10
protection of human health or the environment or imposing liability or
standards of conduct concerning any such chemical material, waste or substance.

                 x.       Neither the Company nor MHI has violated any Federal,
state or local law relating to discrimination in the hiring, promotion or pay
of employees nor any applicable wage or hour laws, nor any provisions of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or the
rules and regulations promulgated thereunder, nor has the Company or MHI
engaged in any unfair labor practice, which in each case might result, singly
or in the aggregate, in a Material Adverse Effect.  There is (i) no significant
unfair labor practice complaint pending against the Company or MHI or, to the
best knowledge of the Company and MHI, threatened against any of them before
the National Labor Relations Board or any state or local labor relations board,
and no significant grievance or significant arbitration proceeding arising out
of or under any collective bargaining agreement is so pending against the
Company or MHI or, to the best knowledge of the Company and MHI, threatened
against any of them, (ii) no significant strike, labor dispute, slowdown or
stoppage pending against the Company or MHI or, to the best knowledge of the
Company and MHI, threatened against the Company or MHI and (iii) to the best
knowledge of the Company and MHI, no union representation question currently
exists with respect to the employees of the Company or MHI and, to the best
knowledge of the Company and MHI, no union organizing activities are taking
place, except (with respect to any matter specified in clause (i), (ii) or
(iii) above, individually or in the aggregate) such as could not have a
Material Adverse Effect.

                 y.       All tax returns required to be filed by the Company
and MHI in any jurisdiction (including foreign jurisdictions) have been so
filed (except to the extent that the failure to make any such filing would not
have a Material Adverse Effect), and all taxes, assessments, fees and other
charges shown thereon to be due and payable have been paid, other than those
being contested in good faith or those currently payable without penalty or
interest.  Neither the Company nor MHI knows of any actual or proposed material
additional tax assessments for any fiscal period against it or MHI.  None of
the Company's nor MHI's tax returns are under audit, and no waivers of the
statute of limitations or extensions of time with respect to any tax returns
have been granted to the Company or MHI, except such as would not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

                 z.       The Company and MHI maintain insurance covering their
properties, operations, personnel and businesses.  In the Company's and MHI's
reasonable judgment, such insurance insures against such losses and risks as
are adequate in accordance with customary industry practice to protect the
Company and MHI and their businesses.  Neither the Company nor MHI has received
notice from any insurer or agent of such insurer that substantial capital
improvements or other expenditures will have to be made in order to continue
such insurance.  All such





                                      -10-
<PAGE>   11
insurance is outstanding and duly in force on the date hereof and will be
outstanding and duly in force on the Closing Date.

                 aa.      The Company and MHI have and, after giving effect to
the Transactions, will have good and defensible title to their interests in oil
and gas properties and good and indefeasible title to all other real and
personal property owned by them, in each case free and clear of all liens and
defects except such as are described in the Offering Memorandum or would not
result in a Material Adverse Effect and do not materially interfere with the
use made or proposed to be made of such properties by the Company and MHI; and
any real property and buildings held under lease by the Company and MHI are
held by them under valid, subsisting and enforceable leases with such
exceptions as would not have a Material Adverse Effect and do not materially
interfere with the use made or proposed to be made of such property and
buildings by the Company and MHI.  Except to the extent described in the
Offering Memorandum, the leases, options to lease, drilling concessions or
other arrangements held by the Company and MHI reflect in all material respects
the rights of the Company and MHI to develop the unexplored and undeveloped
acreage to produce undeveloped oil and natural gas reserves, as described in
the Offering Memorandum.  The Company and MHI have exercised reasonable
diligence, with respect to acquiring or otherwise procuring such leases,
options to lease, drilling concessions and other arrangements, as is customary
in the industry.

                 bb.      The information which was supplied by the Company to
Huddleston & Co., Inc. ("Huddleston"), independent petroleum engineers, for
purposes of evaluating the oil and gas reserves of the Company, Enron Oil & Gas
Company and Conoco Inc. as of December 31, 1997, including, without limitation,
production, costs of operation and development, current prices for production,
agreements relating to current and future operations and sales of production,
was true and correct in all material respects on the dates such estimates were
made and such information was supplied and was prepared in accordance with
customary industry practices, as indicated in the letter of Huddleston included
in the Definitive Memorandum at Annex A (the "Huddleston Letter"); Huddleston
was, as of the date of the Huddleston Letter, and is, as of the date hereof,
independent with respect to the Company and MHI; other than normal production
of the reserves and intervening product price fluctuations, the Company is not
aware of any facts or circumstances that would result in a materially adverse
change in the reserves, or the present value of future net cash flows
therefrom, as described in the Definitive Memorandum and as reflected in the
Huddleston Letter and the reserve report referenced therein; estimates of such
reserves and present values as described in the Definitive Memorandum and
reflected in the Huddleston Letter and the reserve report referenced therein
comply in all material respects to the applicable requirements of Regulation
S-X and Industry Guide 2 under the Securities Act. Except as set forth in the
Definitive Memorandum, there has been no event, trend or condition that





                                      -11-
<PAGE>   12
would have the effect of materially revising downward the estimates of pro
forma proved reserves of the Company as of December 31, 1997.

                 cc.      Except as (i) disclosed to the Initial Purchasers in
writing, (ii) disclosed in or contemplated by the Definitive Memorandum or
(iii) not required to be disclosed in the Definitive Memorandum, the Company is
not engaged in any negotiations, nor is it a party to any existing agreements,
arrangements or understandings, with respect to any acquisitions, combinations
or dispositions of assets or securities that would be material to the Company
and its subsidiaries, taken as a whole.

                 dd.      In reliance upon and subject to the accuracy of the
representations of the Initial Purchasers contained in Section 3 hereof,
neither the execution and delivery of this Agreement and the Registration
Rights Agreement nor the sale of the Notes to be purchased by the Initial
Purchasers is a prohibited transaction (within the meaning of Section 406 of
ERISA or Section 4975 of the Code), with respect to any employee benefit plans
sponsored by the Company or MHI, that is not exempt by statute, regulation or
class exemption.  The Company and MHI are in compliance in all material
respects with all presently applicable provisions of ERISA; no "reportable
event" (as defined in ERISA) has occurred with respect to any "pension plan"
(as defined in ERISA) for which the Company or MHI would have any material
liability; neither the Company nor MHI has incurred or expects to incur
liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any "pension plan" or (ii) Sections 412 (whether or not
waived) or 4971 of the Code; and each "pension plan" for which the Company or
MHI would have any liability that is intended to be qualified under Section
401(a) of the Code is so qualified in all material respects and nothing has
occurred, whether by action or by failure to act, that would cause the loss of
such qualification except, in each case, for any such event as would not have a
Material Adverse Effect.

                 ee.      Other than discounts and commissions of the Initial
Purchasers as described in the Definitive Memorandum, no fees or commissions
will be payable by the Company to any broker, finder or investment banker with
respect to the issuance and sale of any of the Notes pursuant to the terms of
this Agreement.

                 ff.      No statement, representation or warranty made by the
Company or MHI in this Agreement or the Registration Rights Agreement or made
in any certificate or document required by any of the foregoing agreements to
be delivered by the Company or MHI (or their agents, attorneys or
representatives) to the Initial Purchasers, is, was or will be, when made,
inaccurate, untrue or incorrect in any material respect.

                 gg.      Neither the Company nor any agent thereof acting on
its behalf has taken, and none of them will take, any action that might cause
this Agreement or the issuance or sale of the Notes or the Exchange Notes or
the application of proceeds thereof to violate Section 7 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") or any regulation issued
pursuant thereto, including, without limitation, Regulation G, T, U or X of the
Board of Governors of the Federal Reserve System, in each case as in effect now
or as the same may hereafter be in effect on the Issue Date.

                 hh.      The Notes, when issued, will not be of the same class
(within the meaning of Rule 144A under the Securities Act) as other securities
of the Company that are listed on a national securities exchange registered
under Section 6 of the Exchange Act, or quoted in a U.S. automated interdealer
quotation system of a registered national securities association.

                 ii.      No action has been taken and no statute, rule,
regulation or order has been enacted, adopted or issued by any governmental
agency that prevents the issuance of the Notes or prevents or suspends the use
of the Offering Memorandum; no injunction, restraining order or order of any
nature by a federal or state court of competent jurisdiction has been issued
that prevents the issuance of the Notes or prevents or suspends the sale of the
Notes in any jurisdiction referred to in Section 4(e) hereof; and every request
of any securities authority or agency of any jurisdiction for additional
information has been complied with in all material respects.

                 jj.      There are no holders of securities of the Company or
MHI who, by reason of the execution by the Company and MHI of this Agreement or
by the Company of the Registration Rights Agreement, the Indenture or the
Notes, or the consummation by the Company and MHI of the transactions
contemplated hereby and thereby, have the right to request or demand that the
Company or MHI register, under the Securities Act or analogous foreign laws and
regulations, securities held by them in connection with the Exchange Offer.

                 kk.      Neither of the Company nor MHI intends to, nor does
it believe that it will, incur debts beyond its ability to pay such debts as
they mature.  The present fair saleable value of the assets of the Company and
MHI, taken as a whole, exceeds the amount that will be required to be paid on
or in respect of the existing debts and other liabilities (including contingent
liabilities) of the Company and MHI as they become absolute and matured.  The
assets of the Company and MHI, taken as a whole, do not constitute unreasonably
small capital to carry out the business of the Company and MHI taken as a
whole, as conducted or as proposed to be conducted.  Upon the issuance of the
Notes and the consummation of the Transactions, the present fair saleable value
of the assets of the Company and MHI, taken as a whole, will exceed the amount
that will be required to be paid on or in





                                      -13-
<PAGE>   14
respect of the existing debts and other liabilities (including contingent
liabilities) of the Company and MHI, taken as a whole, as they become absolute
and matured.  Upon the issuance of the Notes and the consummation of the
Transactions, the assets of the Company and MHI, taken as a whole, will not
constitute unreasonably small capital to carry out their businesses as now
conducted, including the capital needs of the Company and MHI, taking into
account the projected capital requirements and capital availability of the
Company and MHI, taken as a whole.

                 ll.      Neither the Company nor any of its affiliates or any
person acting on its or their behalf (other than the Initial Purchasers, as to
whom the Company and MHI make no representation) has engaged or will engage in
any directed selling efforts within the meaning of Regulation S under the
Securities Act ("Regulation S") with respect to the Notes.

                 mm.      The Company has not taken, or omitted to take, any
action to cause the Notes offered and sold in reliance on Regulation S to be
offered and sold in transactions other than in offshore transactions.

                 nn.      The sale of the Notes pursuant to Regulation S is not
part of a plan or scheme to evade the registration provisions of the Securities
Act.

                 oo.      The Company, MHI and their respective affiliates and
all persons acting on their behalf (other than the Initial Purchasers, as to
whom the Company and MHI make no representation) have complied with and will
comply with the offering restrictions requirements of Regulation S applicable
to them and their activities in connection with the offering of the Notes
outside the United States and, in connection therewith, the Offering Memorandum
contains or will contain the disclosure required by Rule 902(h) of the
Securities Act.

                 pp.      The Notes sold in reliance on Regulation S will be
represented upon issuance by a temporary global security that may not be
exchanged for definitive securities until the expiration of the 40-day
restricted period referred to in Rule 903(c)(3) of the Securities Act and only
upon certification of beneficial ownership of Notes by non- U.S. persons or
U.S. persons who purchased such Notes in transactions that were exempt from the
registration requirements of the Securities Act.

                 qq.      The industry and market-related data included in the
Offering Memorandum are based on or derived from sources which the Company and
MHI believe to be reliable and accurate in all material respects.

                 rr.      The Company has delivered to the Initial Purchasers
true and correct copies of all documents and agreements related to the
Transactions, including all exhibits and schedules thereto.





                                      -14-
<PAGE>   15
                 ss.      Neither the Company nor MHI has (i) taken, directly
or indirectly, any action designed to, or that might reasonably be expected to,
cause or result in stabilization or manipulation of the price of any security
of the Company or MHI to facilitate the sale and resale of the Notes or (ii)
since the date of the Preliminary Memorandum (A) sold, bid for, purchased or
(B) paid any person (other than the Initial Purchasers pursuant to the terms
herein) any compensation for soliciting another to purchase any other
securities from the Company or MHI.

                 tt.      No registration under the Securities Act of the Notes
is required for the sale of the Notes to the Initial Purchasers or for the
resale of the Notes pursuant to the procedures and upon the terms and subject
to the conditions set forth in this Agreement and the Definitive Memorandum,
assuming the accuracy of the Initial Purchasers' representations set forth in
Section 3 hereof.  No form of general solicitation or general advertising (as
defined in Regulation D under the Securities Act) was used by the Company, MHI
or any of their respective representatives (other than the Initial Purchasers,
as to which the Company and MHI make no representation or warranty) in
connection with the offer and sale of any of the Notes or in connection with
the resale of the Notes pursuant to the procedures and upon the terms and
subject to the conditions set forth in this Agreement and the Definitive
Memorandum, including, but not limited to, articles, notices or other
communications published in any newspaper, magazine, or similar medium or
broadcast over television or radio, or any seminar or meeting whose attendees
have been invited by an general solicitation or advertising.  No securities of
the same class as the Notes have been offered or sold by the Company or MHI
within the six-month period immediately prior to the date hereof.

                 uu.      Each of the Preliminary Memorandum and the Definitive
Memorandum, as of its date, and each amendment or supplement thereto, as of its
date, contains the information specified in, and meets the requirements of,
Rule 144A(d)(4) under the Securities Act.

                 vv.      Each certificate signed by any officer of the Company
or MHI and delivered to the Initial Purchasers or counsel for the Initial
Purchasers shall be deemed to be a representation and warranty by the Company
or MHI, as the case may be, to the Initial Purchasers as to the matters covered
thereby.

         2.      Purchase, Sale and Delivery of the Notes.

                 a.       Subject to the terms and conditions and in reliance
upon the representations, warranties and covenants of the Company, MHI and the
Initial Purchasers herein set forth, the Company agrees to sell to the Initial
Purchasers and the Initial Purchasers agree to purchase from the Company
$135,000,000 principal amount of Notes, in the respective principal amounts set
forth opposite their names





                                      -15-
<PAGE>   16
on Schedule I hereto, at a price of 98.249% of their principal amount.  The
obligations of the Initial Purchasers under this Section 2(a) are several and
not joint.

                 b.       Delivery of the Notes against payment of the purchase
price therefor shall be made at the offices of Fulbright & Jaworski L.L.P.
located at 1301 McKinney, Suite 5100, Houston, Texas 77010, or such other
location as may be mutually acceptable to the Initial Purchasers and the
Company.  Such delivery and payment shall be made at 10:00 a.m., New York time,
on the third full business day next following the date of this Agreement, or at
such other time as shall be agreed upon by the Initial Purchasers and the
Company.  The time and date of such delivery and payment are herein called the
"Closing Date."  One or more certificates evidencing beneficial interests in
the Notes registered in the name of Cede & Co., as nominee of The Depository
Trust Company ("DTC"), or in the name of such other eligible nominee of DTC
identified by the Initial Purchasers to the Company in writing at least two
full business days prior to the Closing Date, in the principal amounts
corresponding to the aggregate principal amount of the Notes (the "Global
Notes") shall be delivered to the Initial Purchasers by the Company, against
payment of the purchase price therefor by wire transfer of same day funds, to
an account designated by the Company, provided that the Company shall give at
least one business day's prior written notice to the Initial Purchasers of the
information required to effect such wire transfer.

                 c.       The Company will permit the Initial Purchasers to
examine and package the Global Notes for delivery at least one full business
day prior to the Closing Date.

                 d.       It is understood that each certificate evidencing a
Note shall bear a legend substantially to the following effect:

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY
         STATE.  THE HOLDER HEREOF, BY PURCHASING THIS SECURITY, AGREES FOR THE
         BENEFIT OF THE COMPANY THAT THIS SECURITY MAY NOT BE RESOLD, PLEDGED
         OR OTHERWISE TRANSFERRED (X) PRIOR TO THE SECOND ANNIVERSARY OF THE
         ISSUANCE HEREOF (OR A PREDECESSOR SECURITY HERETO) OR (Y) BY ANY
         HOLDER THAT WAS AN AFFILIATE OF THE COMPANY AT ANY TIME DURING THE
         THREE MONTHS PRECEDING THE DATE OF SUCH TRANSFER, IN EITHER CASE OTHER
         THAN (1) TO THE COMPANY (2) SO LONG AS THIS SECURITY IS ELIGIBLE FOR
         RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT ("RULE 144A"),
         TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED
         INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A

         PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
         INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE RESALE, PLEDGE OR
         OTHER 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 THIS SECURITY), (3) PURSUANT TO OFFERS AND SALES TO
         NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES IN A TRANSACTION
         MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT, (4) TO
         AN INSTITUTION THAT IS AN "ACCREDITED INVESTOR" AS DEFINED IN RULE
         501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT (AS INDICATED BY
         THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER ON

         FORM ATTACHED TO THIS SECURITY IS DELIVERED BY THE TRANSFEREE TO THE
         COMPANY AND THE TRUSTEE, (5) PURSUANT TO AN EXEMPTION FROM

         3. Offering and Resale of the NOTES.

         Each Initial Purchaser hereby acknowledges that the Notes have not
been registered under the Securities Act and that they are being offered and
sold pursuant to an exemption from registration contained in the Securities Act
based in part on its representations contained in this Agreement, including,
without limitation, the following: it has substantial experience in evaluating
and investing in private placement transactions of securities in companies
similar to the Company so that it is capable of evaluating the merits and risks
of its investment in the Company; it acknowledges that it must bear the
economic risk of this investment indefinitely unless the Notes are registered
under the Securities Act or an exemption from registration is available; it has
received and read the Offering Memorandum and has had an opportunity to discuss
the Company's business, management and financial affairs with directors,
officers and other management of the Company and ask questions of, and receive
answers from, the Company and its management regarding the terms and conditions
of its investment in the Company.  Each Initial Purchaser represents and
warrants that it is a qualified institutional buyer (as defined in Rule 144A
under the Securities Act ("QIBs")).  Each Initial Purchaser agrees with the
Company that (a) it has not and will not solicit offers for, or offer or sell,
the Notes by any form of general solicitation or general advertising (as those
terms are used in Regulation D under the Securities Act) or in any manner
involving a public offering within the meaning of Section 4(2) of the
Securities Act and the rules and regulations promulgated thereunder, and (b) in
connection with the initial placement of the Notes, it has and will solicit
offers for the Notes only from, and will offer the Notes only (i) to persons
whom it reasonably believes to be QIBs in accordance with Rule 144A, to whom
notice has been given that such sale or delivery is being made in reliance on
Rule 144A under the Securities Act, and, in each case, in transactions under
Rule 144A, or (ii) outside the United States in reliance on Regulation S under
the Securities Act.  The Initial Purchaser agrees that it will not offer, sell
or deliver any of the Notes in any jurisdiction outside the United States, its
territories and possessions except under circumstances that will result in
compliance with the provisions of Regulation S under the Securities Act and the
applicable laws of such jurisdiction.  Each Initial Purchaser understands that
no action has been taken to permit a public offering of the Notes in any
jurisdiction within or without the United States where action would be required
for such purpose.  Each Initial Purchaser agrees not to cause any advertisement
of the Notes to be published in any newspaper or periodical or posted in any
public place and not to issue any circular relating to the Notes, except in any
such case with the consent of the Company.  Each Initial Purchaser agrees to
send and give a copy of the Definitive Memorandum (as the same may be
supplemented or amended) to each purchaser of the Notes in connection with
written confirmation of the sale of the Notes to such person.

         4.      Agreements of the Company and MHI.

         The Company and MHI, jointly and severally, agree with the Initial
Purchasers as follows:





                                      -18-
<PAGE>   19
                 a.       The Company and MHI will advise the Initial
Purchasers promptly (and, if so requested by the Initial Purchasers, will
confirm such advice in writing) of (i) the occurrence, during the period
referred to in paragraph (d) below, of any event of which the Company or MHI
have knowledge that makes any statement of a material fact made in the
Definitive Memorandum untrue or that requires the addition of any statement of
a material fact to, or other material change in, the Definitive Memorandum in
order to make the statements therein, in light of the circumstances existing
when it is delivered to a purchaser, not misleading and (ii) the issuance by
any state securities commission of any stop order suspending the qualification
or exemption from qualification of the Notes for offering or sale in any
jurisdiction, or the initiation of any proceeding for such purpose by any state
securities commission or other regulatory authority.  The Company and MHI shall
use their reasonable best efforts to prevent the issuance of any stop order or
order suspending the qualification or exemption of any Notes under any state
securities or "Blue Sky" laws and, if at any time any state securities
commission or other regulatory authority shall issue an order suspending the
qualification or exemption of any Notes under any state securities or "Blue
Sky" laws, the Company and MHI shall use their reasonable best efforts to
obtain the withdrawal or lifting of such order at the earliest possible time.

                 b.       The Company will furnish to the Initial Purchasers
and to those persons whom the Initial Purchasers identify to the Company such
number of copies of the Definitive Memorandum, and any amendments thereof or
supplements thereto, as the Initial Purchasers may reasonably request.

                 c.       The Company (i) will not make any amendment of or
supplement to the Offering Memorandum regarding which the Initial Purchasers
shall not previously have been consulted or use any such proposed amendment or
supplement to which the Initial Purchasers shall reasonably and in good faith
object and (ii) shall promptly prepare, upon the Initial Purchaser's request,
any amendment or supplement to the Offering Memorandum that in the opinion of
counsel to the Initial Purchasers may be necessary or advisable in connection
with resales by the Initial Purchasers pursuant to the procedures and upon the
terms and subject to the conditions set forth in the Offering Memorandum.

                 d.       If, during the period from the date of the Definitive
Memorandum through the Closing Date, and for so long thereafter as in the
opinion of the Initial Purchasers' counsel the Definitive Memorandum is
required to be delivered in connection with resales of the Notes by the Initial
Purchasers, any event shall occur as a result of which it becomes necessary to
amend or supplement the Definitive Memorandum in order that the Definitive
Memorandum will not include an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein not
misleading in light of the circumstances existing when the Definitive
Memorandum is or is to be delivered to a purchaser, or if it





                                      -19-
<PAGE>   20
becomes necessary to amend or supplement the Definitive Memorandum to comply
with any law, the Company promptly will prepare an appropriate amendment of or
supplement to the Definitive Memorandum so that the Definitive Memorandum, as
so amended or supplemented, does not include such untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein not misleading, in light of the circumstances existing when
it is so delivered, or so that the Definitive Memorandum will comply with law,
and the Company will furnish to the Initial Purchasers such number of copies
thereof as they reasonably may request.

                 e.       The Company will cooperate with the Initial
Purchasers and their counsel in connection with the registration or
qualification of the Notes under the securities or "Blue Sky" laws of such
jurisdictions as they may request, will continue such qualification in effect
for so long as required to permit the continuance of sales of and dealings in
the Notes within such jurisdictions to complete the resale by them of all of
the Notes as specified in Section 3 hereof, and will file such consents to
service of process or other documents as may be necessary in order to effect
such registration or qualification; provided, however, that the Company shall
not be required in connection therewith to register or qualify as a foreign
corporation where it is not now so qualified or to take any action that would
subject it to taxation or service of process.

                 f.       So long as any of the Notes are outstanding, the
Company or MHI will furnish to the Initial Purchasers as soon as available a
copy of each report mailed generally by the Company or MHI to holders of Common
Stock of the Company or MHI or filed by the Company or MHI with the Commission,
whether such report or filing is required by the Indenture or otherwise, and
such other publicly available information concerning the Company or MHI as the
Initial Purchasers reasonably may request.

                 g.       So long as and at any time that the Notes are
outstanding and are "restricted securities" within the meaning of Rule
144(a)(3) under the Securities Act and the Company is not subject to Section 13
or 15(d) of the Exchange Act, the Company, upon request of any holder of the
Notes, will furnish to such holder, and to any prospective purchaser or
purchasers of the Notes, designated by such holder, information satisfying the
requirements of subsection (d)(4)(i) of Rule 144A under the Securities Act.

                 h.       The Company and MHI will use their best efforts, and
will cooperate with the Initial Purchasers, to cause the Notes to be eligible
for inclusion in the Private Offerings, Resales and Trading through Automated
Linkages ("PORTAL") market of the National Association of Securities Dealers,
Inc. ("NASD") and to obtain approval of the Notes by DTC for "book-entry"
transfer.





                                      -20-
<PAGE>   21
                 i.       The Company and MHI will not, and will not authorize
or knowingly permit any person acting on their behalf to, offer to sell or
solicit offers to buy any of the Notes by means of any form of general
solicitation or general advertising within the meaning of Section 502(c) under
Regulation D under the Securities Act or in any manner involving a public
offering or distribution of the Notes within the meaning of the Securities Act.

                 j.       The Company shall not take any action or omit to take
any action, which taking or omission, as the case may be, would result in the
Company becoming an "investment company" or a company controlled by an
"investment company" within the meaning of, or require the Company to register
as an "investment company" under, the Investment Company Act of 1940, as
amended.

                 k.       Whether or not the transaction contemplated by this
Agreement is consummated or this Agreement becomes effective or is terminated,
to pay all costs, expenses, fees and taxes incident to the performance of the

Memorandum (including, without limitation, financial statements) and all
amendments and supplements thereto required pursuant hereto, (ii) the
preparation (including, without limitation, duplication costs) and delivery of
all preliminary and final Blue Sky Memoranda and all other agreements,
memoranda, correspondence and all other documents prepared and delivered in
connection herewith and with resales by the Initial Purchasers (other than the
cost of preparation of this Agreement and the Registration Rights Agreement),
(iii) the issuance, transfer and delivery of the Notes to the Initial
Purchasers, (iv) the qualification or registration of the Notes for offer and
sale under the securities or Blue Sky laws of the several states (including,
without limitation, the cost of printing and mailing a preliminary and final
Blue Sky Memorandum and the reasonable fees and disbursements of counsel for
the Initial Purchasers relating thereto), (v) furnishing such copies of the
Offering Memorandum, and all amendments and supplements thereto, as may be
requested for use in connection with resales by the Initial Purchasers, (vi)
the preparation of certificates for the Notes (including, without limitation,
printing and engraving thereof), (vii) the fees, disbursements and expenses of
the Company's and MHI's counsel and accountants, (viii) all fees and expenses
(including fees and expenses of counsel) of the Company and MHI in connection
with the approval of the Notes by DTC for "book-entry" transfer, (ix) rating
the Notes by the rating agencies, (x) the reasonable fees and expenses of the
Trustee and its counsel, (xi) the performance by the Company and MHI of their

Section 9(c), the Initial Purchasers shall pay their own costs and expenses,
including the costs and expenses of their counsel.

                 l.       The Company will apply the net proceeds from the sale
of the Notes as set forth under the caption "Use of Proceeds" in the Definitive
Memorandum.

                 m.       The Company and MHI will not (and will direct their
affiliates not to) take, directly or indirectly, any action that is designed,
or might reasonably be expected, to cause or result in the stabilization or
manipulation of the price of any security of the Company or MHI to facilitate
the sale or resale of the Notes.  Except as permitted by the Securities Act,
neither the Company nor MHI will distribute any (i) preliminary offering
memorandum, including, without limitation, the Preliminary Memorandum, (ii)
definitive offering memorandum, including, without limitation, the Definitive
Memorandum, or (iii) other offering material in connection with the offering
and sale of the Notes.

                 n.       During the period beginning from the date hereof and
continuing to and including the date which is six months after the Closing
Date, neither the Company nor any affiliate thereof shall sell, offer for sale,
solicit offers to buy or otherwise negotiate in respect of the sale of any
"security" (as defined in Section 2(1) of the Securities Act) of the same or a
similar class as the Notes, other than as contemplated by the Registration
Rights Agreement.

                 o.       The Company and MHI will use their reasonable best
efforts to do and perform all things required or necessary to be done and
performed under this Agreement by them prior to the Closing Date and to satisfy
all conditions precedent to the delivery of the Notes.

                 p.       Not to sell, offer for sale or solicit offers to buy
or otherwise negotiate in respect of any security (as defined in the Securities
Act) that would be integrated with the sale of the Notes, in a manner that
would require the registration under the Securities Act of the sale to the
Initial Purchasers or the resale by the Initial Purchasers to QIBs or to
non-U.S. persons outside the United States in reliance upon Regulation S of the
Notes or to take any action that would result in the resales by the Initial
Purchasers not being exempt from registration under the Securities Act.

                 q.       To comply with all of its agreements set forth in the
Registration Rights Agreement and all agreements set forth in the
representations letter of the Company to DTC relating to the approval of the
Notes by DTC for "book-entry" transfer.

                 r.       Prior to the Closing Date, to furnish to the Initial
Purchasers, as soon as they have been prepared in the ordinary course by the
Company, copies of any unaudited interim financial statements for any period
subsequent to the periods covered by the financial statements appearing in the
Offering Memorandum.

         5.      Indemnification.

                 a.       The Company and MHI, jointly and severally, agree to
indemnify and hold harmless each Initial Purchaser, its directors, officers and
employees and each person, if any, who controls such Initial Purchaser, now or
hereafter, and their directors, officers and employees within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act (the Initial
Purchasers and each such person being sometimes hereafter referred to as an
"Indemnified Person"), from and against any and all losses, claims, damages,
awards, liabilities and judgments (collectively, "Losses") arising out of or
based upon any untrue statement or alleged untrue statement of a material fact
contained in the Offering Memorandum or in any amendments thereof or
supplements thereto (including, without limitation, the financial statements,
accounting and statistical data included therein and the related notes
thereto), or by any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading,
except insofar as, and only to the extent that, such Losses arise out of or are
based upon any such untrue statement or omission or alleged untrue statement or
omission based upon the information relating to such Initial Purchaser
furnished by it to the Company expressly for use therein and used in conformity
therewith.  This indemnity is and will be in addition to any liability which
the Company and MHI otherwise may have.

                 b.       In case any action or proceeding (including any
governmental investigation or inquiry) shall be brought or asserted against an
Indemnified Person, or notice of any such claim is received, with respect to
which indemnity may be sought against the Company or MHI, such Indemnified
Person shall promptly notify the Company and MHI in writing and the Company and
MHI shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to such Indemnified Person and the payment of all
reasonable fees and expenses of such defense; provided that the failure by any
such Indemnified Person to so notify the Company and MHI shall not relieve the
Company and MHI of their indemnification obligations under Sections 5(a) and
(b) hereof, except to the extent that the Company and MHI are materially
prejudiced or forfeit substantive rights and defenses by reason of such
failure.  Such Indemnified Person shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified
Person, unless (i) the employment of such counsel has been authorized in
writing by the Company and MHI, (ii) the Company and MHI have failed promptly
to assume the defense and employ counsel (reasonably satisfactory to such
Indemnified Person), or





                                      -23-
<PAGE>   24
(iii) the named parties to any such action (including any impleaded parties)
include both such Indemnified Person and the Company or MHI, and such
Indemnified Person shall have been advised by such counsel that there may be
one or more legal defenses available to such Indemnified Person that are
different from or additional to those available to the Company or MHI, as the
case may be, and in the reasonable judgment of such counsel it is advisable for
such Indemnified Party to employ separate counsel (in all of which cases, if
such Indemnified Person notifies the Company and MHI in writing that it elects
to employ separate counsel at the expense of the Company and MHI, the Company
and MHI shall not have the right to assume the defense of such action on behalf
such Indemnified Person; it being understood, however, that the Company and MHI
shall not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for such Indemnified Person and any other Indemnified Persons, which
firm shall be designated in writing by such Indemnified Persons (which shall be
reasonably satisfactory to the Company and MHI) and that all such fees and
expenses shall be reimbursed promptly as they are billed.  The Company and MHI
shall not be liable for any settlement of any such action or proceeding
effected without their written consent (not to be unreasonably withheld) and if
settled with their written consent or if there is a final, unappealable
judgment for the plaintiff, the Company and MHI agree to jointly and severally
indemnify and hold harmless such Indemnified Persons from and against any loss
or liability by reason of such settlement or judgment.  Without limiting the
generality of the foregoing, the Company and MHI shall not effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Person is or has been threatened to be made a party where indemnity
could have been sought hereunder by such Indemnified Person unless the Company
and MHI shall have obtained the prior written consent of such Indemnified
Person (not to be unreasonably withheld); provided, however, that the Company
and MHI may effect such a settlement without the consent of such Indemnified
Person if such settlement includes an unconditional release of such Indemnified
Person from all liability for claims that are the subject matter of such
proceeding or the Company and MHI indemnify such Indemnified Person in writing
and post a bond for an amount equal to the maximum liability for all such
claims as contemplated above or provide other security for such indemnity as
shall be reasonably satisfactory to such Indemnified Person.

                 c.       Each Initial Purchaser agrees, severally and not
jointly, to indemnify and hold harmless the Company and MHI, their directors,
officers and employees and each person, if any, controlling the Company and MHI
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act from and against any and all Losses to the same extent as the
foregoing indemnity from the Company and MHI to the Initial Purchasers but only
with respect to information relating to such Initial Purchaser furnished in
writing by such Initial Purchaser





                                      -24-
<PAGE>   25
expressly for use in the Offering Memorandum or any amendment thereof or
supplement thereto and used in conformity therewith; provided, however, that in
no case shall any Initial Purchaser be liable or responsible for any amount in
excess of the discounts and commissions received by the Initial Purchaser in
connection with the sale of the Notes, as set forth on the cover page of the
Offering Memorandum.  In case any action or proceeding shall be brought against
the Company and MHI, any of their directors, any of their officers or any such
controlling person based on the Offering Memorandum or any amendment thereof or
supplement thereto and in respect of which indemnity may be sought against an
Initial Purchaser, such Initial Purchaser shall have the same rights and duties
as are given to the Company and MHI by Section 5(b) hereof (except that if the
Company and MHI shall have assumed the defense thereof, such Initial Purchaser
shall not be required to do so, and in such case such Initial Purchaser may
employ separate counsel therein and participate in the defense thereof but the
fees and expenses of such counsel shall be at such Initial Purchaser's
expense), and the Company, MHI, their directors, officers and employees and
each such controlling person shall have the same rights and duties as are given
to such Initial Purchaser by Section 5(b) hereof.  The Company and MHI
acknowledge that the only information furnished in writing by or on behalf of
any Initial Purchaser expressly for use in the Offering Memorandum consists of
the following: (i) the last full paragraph of text appearing on the outside
front cover page of the Definitive Memorandum, (ii) the names of the Initial
Purchasers in the form they appear on the outside front cover page of the
Definitive Memorandum and in the table under the caption "Plan of Distribution"
in the Definitive Memorandum, (iii) the first sentence of the second paragraph
following the table under the caption "Plan of Distribution" in the Definitive
Memorandum, (iv) the third sentence of the third paragraph following the table
under the caption "Plan of Distribution" in the Definitive Memorandum and (v)
the first sentence of the fifth paragraph following the table under the caption
"Plan of Distribution" in the Definitive Memorandum.

                 d.       If the indemnification provided for in this Section 5
is unavailable to or otherwise insufficient to hold harmless an indemnified
party in respect of any Losses (other than by reason of exceptions provided in
such Section), then the party who would otherwise be responsible for such
indemnification, in lieu of, or in addition to, indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such Losses (i) in such proportion as is appropriate to reflect
the relative benefits received by the indemnifying party on the one hand and
the indemnified party on the other hand from the offering of the Notes or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
indemnifying party and the indemnified party in connection with the statements
or omissions which resulted in such Losses, as well as any other relevant
equitable considerations.  The relative benefits received by the Company and
MHI and an Initial Purchaser shall be deemed to be in the same proportion as
the total net proceeds from the





                                      -25-
<PAGE>   26
Offering (before deducting expenses) received by the Company and MHI, and the
total discounts and commissions received by such Initial Purchasers, bear to
the total price of the Notes to investors, in each case as set forth in the
table on the cover page of the Definitive Memorandum.  The relative fault of
the Company and MHI and such Initial Purchaser shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company and MHI or such Initial
Purchaser and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

         The Company and MHI and the Initial Purchasers agree that it would not
be just and equitable if contribution pursuant to this Section 5(d) were
determined by pro rata allocation or by any other method of allocation that
does not take account of the equitable considerations referred to in the
immediately preceding paragraph.  The amount paid or payable by an indemnified
party as a result of Losses shall be deemed to include, subject to the
limitations set forth above, any legal or other fees or expenses reasonably
incurred by such indemnified party in connection with investigating or
defending any such action or claim.  Notwithstanding the provisions of this
Section 5, each Initial Purchaser shall not be required to contribute any
amount in excess of the amount of the total discount applicable to the Notes
purchased by such Initial Purchaser.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  For purposes of this Section 5(d), each
director, officer and employee of an Initial Purchaser or the Company and MHI,
and each person, if any, who controls an Initial Purchaser or the Company and
MHI within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, shall have the same rights to contribution as such Initial
Purchaser or the Company and MHI, as the case may be.

         6.      Conditions of the Initial Purchasers' Obligations.

         The Initial Purchasers' obligations to purchase and pay for the Notes
shall be subject to (i) the accuracy of the representations and warranties of
the Company and MHI herein contained as of the date hereof and as of the
Closing Date, (ii) the absence in any certificates, opinions, written
statements or letters furnished pursuant to this Section 6 to the Initial
Purchasers or to their counsel, of any qualification or limitation not

Company and MHI of their respective obligations hereunder required to be

stock or in the long-term debt of the Company or MHI from that set forth in or

                 c.       As to each Initial Purchaser, the purchase of and

reasonably be expected to result in a Material Adverse Effect; and no stop
order shall have been issued preventing the use of the Offering Memorandum, or
any amendment or supplement thereto, or which could reasonably be expected to
have a Material Adverse Effect, on the condition, financial or otherwise, or
the earnings, business affairs or business prospects of the Company and MHI,
taken as a whole.

the Closing Date by the Initial Purchasers upon notice to the Company and MHI
if any of the following has occurred:  (i) since the respective dates as of

adverse change, or any development involving a prospective material adverse
change, in the financial condition, business, properties, prospects, oil and
gas reserves, net worth or results of operations of the Company and MHI, taken

it impracticable to market the Notes on the terms and in the manner
contemplated in the Offering Memorandum, (ii) any outbreak or escalation of
hostilities or other national or international calamity or crisis or material
adverse change in economic conditions, if the effect of such outbreak,
escalation, calamity, crisis or change on the financial markets of the United

impracticable to market the Notes on the terms and in the manner specified in
the Offering Memorandum, (iii) any suspension of trading in securities on the

Market or the imposition of any limitation on prices (other than limitations on

York State authorities, (vi) the taking of any action by any federal, state or

effect on the financial markets in the United States, or (viii) there shall
have been such a material adverse change in general economic, political or
financial conditions or if the effect of international conditions on the
financial markets in the United States shall be such as, in the Initial
Purchasers' judgment, makes it inadvisable or impracticable to market the Notes
on the terms and in the manner contemplated in the Offering Memorandum.

         8.      Default by One or More of the Initial Purchasers.  If one or
more of the Initial Purchasers shall fail on the Closing Date to purchase the
Notes that it or they are obligated to purchase under this Agreement (the
"Defaulted Notes") and (i) if the aggregate principal amount of the Defaulted
Notes does not exceed 10% of the aggregate principal amount of the Notes
purchased hereunder, the non-defaulting Initial Purchasers shall be obligated
to purchase the Defaulted Notes in the same proportion as the amount set forth
opposite their names on Schedule I bears to the aggregate principal amount of
the Notes purchased hereunder or (ii) if the aggregate principal amount of the
Defaulted Notes equals or exceeds 10% of the aggregate principal amount of the
Notes purchased hereunder, the non-defaulting Initial Purchasers shall have the
right, but not the obligation, within five days thereafter, to make
arrangements for one of more of the non-defaulting Initial Purchasers to
purchase all, but not less than all, of the Defaulted Notes in such amounts as
may be agreed upon and upon the terms herein set forth; if, however, the
non-defaulting Initial Purchasers shall not have completed such arrangements
within such five-day period, then this Agreement shall terminate without
liability on the part of any non-defaulting Initial Purchaser, the Company or
MHI.  No action taken pursuant to this Section 8 shall relieve any defaulting
Initial Purchaser from liability in respect of its default.

representations, warranties and other statements of the Company and MHI and the
Initial Purchasers set forth in or made pursuant to this Agreement shall remain

payment for the Notes, regardless of (i) any investigation, or statement as to
the results thereof, made by or on behalf of the officers or directors of any
of the Company and MHI or any controlling person of the Company or MHI and (ii)
acceptance of the Notes and payment for them hereunder.  The respective

                 c.       If this Agreement shall be terminated by the Initial
Purchasers because of any failure or refusal on the part of the Company or MHI
to comply with the terms or to fulfill any of the conditions of this Agreement,
the Company and MHI shall reimburse the Initial Purchasers for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by them in connection with the offering of the Notes.

                 d.       Except as otherwise provided, this Agreement has been
and is made solely for the benefit of and shall be binding upon the Company and
MHI, their respective directors and officers, the Initial Purchasers, any
controlling persons referred to herein and their respective successors and
assigns, all as and to the extent provided in this Agreement, and no other
person shall acquire or have any right under or by virtue of this Agreement.
The term "successors and assigns" shall not include a purchaser of any of the
Notes from the Initial Purchasers merely because of such purchase.
Notwithstanding the foregoing it is expressly understood and agreed that each
purchaser of the Notes from the Initial Purchasers is intended to be a
beneficiary of the Company's and MHI's covenants contained in the Registration
Rights Agreement to the same extent as if the Notes were sold and those
covenants were made directly to such purchaser by the Company and MHI, and each
such purchaser shall have the right to take action against either of the
Company and MHI to enforce, and obtain monetary recovery for damages resulting
from any breach of, those covenants.

                 e.       This Agreement shall be governed by and construed in
accordance with the laws of the State of New York applicable to instruments
made and performed wholly in such state and without regard to the choice of law
provisions of such state.

                 f.       This Agreement may be signed in counterparts, all of
which taken together shall constitute but one and the same original instrument.

         Please confirm that the foregoing correctly sets forth the mutual
agreement and understanding between the Company, MHI and the Initial Purchasers
as to the subject matter herein set forth.

         Each party agrees as follows for the benefit of the other parties and
for the equal and ratable benefit of the Holders of the Company's 11 1/2%
Series A Senior Notes due 2005 (as issued pursuant to, and as may be amended or
supplemented from time to time in accordance with, the terms of this Indenture,
the "SERIES A NOTES") and the Company's 11 1/2% Series B Senior Notes due 2005
(as issued pursuant to, and as may be amended or supplemented from time to time
in accordance with, the terms of this Indenture, the "SERIES B NOTES", and
together with the Series A Notes, collectively the "SECURITIES"), without
preference of one series of Notes over the other.

                                   ARTICLE 1.

                   DEFINITIONS AND INCORPORATION BY REFERENCE

Section  1.1.    DEFINITIONS.

         "144A GLOBAL NOTE" means a permanent global senior note that contains
the paragraph referred to in footnote 1 and the additional schedule referred to
in footnote 3 to the form of the Security attached hereto as Exhibit A-1, and
that is deposited with the Securities Custodian and registered in the name of
the Depository or its nominee, representing a series of Securities sold in
reliance on Rule 144A or another exemption from the registration requirements
of the Securities Act, other than Regulation S.

         "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 Section 4.9(a), all or any
part of an increase in





<PAGE>   8
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

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

law, stock exchange rule or usage.  Each Security shall be dated the date of
its authentication.  The Securities shall be issued in denominations of $1,000
and integral multiples thereof.

         The Series A Notes and the Series B Notes shall be considered

         The terms and provisions contained in the Securities shall constitute,
and are hereby expressly made, a part of this Indenture and the Company, the
Guarantors and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby; provided,
if any provision of any Security conflicts with the express provisions of this
Indenture, such provisions of this Indenture shall govern and be controlling.

         (b)     Global Notes.  Series A Notes offered and sold to QIBs in
reliance on Rule 144A shall be issued initially in the form of one or more 144A
Global Notes, which shall be deposited on behalf of the purchasers of the
Series A Notes represented thereby with the Securities Custodian and registered
in the name of the Depository or a nominee of the Depository, duly executed by
the Company and authenticated by the Trustee as hereinafter provided.  The
aggregate principal amount of the 144A Global Notes may from time to time be
increased or decreased by adjustments made on the records of the Trustee and
the Depository or its nominee, as the case may be, in connection with transfers
of interests as hereinafter provided.

         Series A Notes offered and sold in reliance on Regulation S, if any,
shall be issued initially in the form of the Regulation S Temporary Global
Note, which shall be deposited on behalf of the purchasers of the Series A
Notes represented thereby with the Securities Custodian and registered in the
name of the Depository or the nominee of the Depository for the accounts of
designated agents holding on behalf of Euroclear or Cedel, duly executed by the
Company and authenticated by the Trustee as hereinafter provided.  The "40-day
restricted period" (as defined in Regulation S) shall be terminated upon the
receipt by the Trustee of (i) a written certificate from the Depository,
together with copies of certificates from Euroclear and Cedel certifying that
they have received certification of non-United States beneficial ownership of
100% of the aggregate principal amount of the Regulation S Temporary Global
Note (except to the extent of any beneficial owners thereof who acquired an
interest therein pursuant to another exemption from registration under the
Securities Act and who will take delivery of a beneficial ownership interest in
a 144A Global Note, all as contemplated by Section 2.6(a)(ii)), and (ii) an
Officers' Certificate from the Company confirming the foregoing.  Following the
termination of the 40-day restricted period, beneficial interests in the
Regulation S Temporary Global Note shall be exchanged for beneficial interests
in one or more Regulation S Permanent Global Notes pursuant to the Applicable
Procedures.  Simultaneously with the authentication of Regulation S Permanent
Global Notes, the Trustee shall cancel the Regulation S Temporary Global Note.
The aggregate principal amount of the Regulation S Temporary Global Note and
the Regulation S Permanent Global Notes may from time to time be increased or
decreased by adjustments made on the records of the Trustee and the Depository
or its nominee, as the case may be, in connection with transfers of interests
as hereinafter provided.

         Each Global Note shall represent such of the outstanding Securities as
shall be specified therein and each shall provide that it shall represent the
aggregate amount of outstanding Securities from time to time endorsed thereon
and that the aggregate amount of outstanding Securities represented thereby may
from time to time be reduced or increased, as appropriate, to reflect
exchanges, redemptions and transfers of interests.  Any endorsement of a Global
Note to reflect the amount of any increase or decrease in the amount of
outstanding Securities represented thereby shall be made by the Trustee or the
Securities Custodian, at the direction of the Trustee, in accordance with
instructions given by the Holder thereof as required by Section 2.6.

         The provisions of the "Operating Procedures of the Euroclear System"
and "Terms and Conditions Governing Use of Euroclear" and the "Management
Regulations" and "Instructions to Participants" of Cedel shall be applicable to
interests in the Regulation S Temporary Global Note and the Regulation S
Permanent Global Notes, if any, that are held by Participants through Euroclear
or Cedel.  The Trustee shall have no obligation to notify Holders of any such
procedures or to monitor or enforce compliance with the same.

         (c)     Book-Entry Provisions.  Participants shall have no rights
either under this Indenture with respect to any Global Note held on their
behalf by the Depository or by the Securities Custodian as custodian for the
Depository or under such Global Note, and the Depository may be treated by the
Company, the Trustee and any Agent of the Company or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any Agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its Participants, the operation of
customary practices of such Depository governing the exercise of the rights of
an owner of a beneficial interest in any Global Note.

         (d)     Definitive Securities.  Securities issued in definitive form
under circumstances herein expressly provided shall be in the form of
Definitive Securities, duly executed by the Company and authenticated by the
Trustee as herein provided.

SECTION  2.2.    EXECUTION AND AUTHENTICATION.

         Two Officers of the Company shall sign the Securities on behalf of the
Company, and one Officer of each Guarantor shall sign the notation on the
Securities relating to the Guarantee of such Guarantor on behalf of such
Guarantor, in each case by manual or facsimile signature.  The Company's seal
shall be reproduced on the Securities.

         If an Officer of the Company or any Guarantor whose signature is on a
Security no longer holds that office at the time the Security is authenticated,
the Security shall be valid nevertheless.

         A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security and
the Guarantee.  These signatures shall be conclusive  evidence that the
Security has been authenticated under this Indenture.  Each Security shall be
dated the date of its authentication.

         The Trustee shall authenticate (i) the Series A Notes for original
issue up to the aggregate principal amount of $135,000,000 and (ii) the Series
B Notes from time to time for issue only in exchange for a like principal
amount of Series A Notes, in each case, upon a written order of the Company
signed by two Officers of the Company, which written order shall specify (x)
the amount of Securities to be authenticated, (y) whether the Securities are
Series A Notes or Series B Notes and (z) the amount of Securities to be issued
in global form or definitive form.  Subject to Section 2.7, the aggregate
principal amount of Securities outstanding at any time may not exceed
$135,000,000.  Each Security authenticated for original issuance shall bear the
Restricted Legend.

         The Trustee may appoint an authenticating agent to authenticate
Securities.  An authenticating agent may authenticate Securities whenever the
Trustee may do so, except on original issuance.  Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent and each reference to authentication of the Securities includes
authentication of the Guarantee.  An authenticating agent has the same rights
as an Agent to deal with the Company or its Affiliates.

         The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and any integral multiple thereof.

SECTION  2.3.    REGISTRAR AND PAYING AGENT.

         The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange (the "REGISTRAR") and an
office or agency where Securities may be presented for payment (the "PAYING
AGENT").  The Registrar shall keep a register of the Securities and of their
transfer and exchange.  Where the Trustee is acting as or has been appointed
Registrar and/or Paying Agent, the Company may appoint one or more
co-registrars and one or more additional paying agents with the prior consent
of the Trustee, whose consent shall not be unreasonably withheld.  The term
"Paying Agent" includes any additional paying agent.

         The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, and such agreement shall incorporate the
TIA's provisions of this Indenture that relate to such Agent.  Such agency
agreement shall provide for reasonable compensation for such services and
otherwise shall implement the provisions of this Indenture that relate to
Agent.  The Company shall notify the Trustee of the name and address of any
Agent and shall furnish the Trustee with an executed counterpart of any such
agency agreement.  If the Company fails to maintain or act as Registrar or
Paying Agent, the Trustee shall act as such and shall be duly compensated
therefor.

         The Registrar or a co-registrar and a Paying Agent shall be maintained
by the Company in the Borough of Manhattan, the City of New York.  The Company
initially designates the Trustee as the Registrar and Paying Agent.

         The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Notes.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Securities Custodian with respect to the Global
Notes.

SECTION  2.4.    PAYING AGENT TO HOLD MONEY IN TRUST.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that such Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by such Paying Agent for the payment of
principal of, or premium, if any, interest or Liquidated Damages, if any, on,
the Securities (whether such money shall have been paid to it by the Company or
any Guarantor), and will notify the Trustee of any Default by the Company or
any Guarantor in making any such payment.  While any such Default continues,
the Trustee may require the Paying Agent to pay all money held by it to the
Trustee.  Except as provided in the immediately preceding sentence, the Company
at any time may require a Paying Agent to pay all money held by it to the
Trustee and to account for any funds disbursed and, if the Company requires
such payment, the Company shall give prior notice to the Trustee and provide
appropriate money transfer instructions to the Paying Agent.  Upon such payment
over to the Trustee and accounting for any funds disbursed, such Paying Agent
(if other than the Company or a Guarantor) shall have no further liability for
the money.  If the Company or a Guarantor acts as Paying Agent, it shall
segregate and hold as separate trust funds for the benefit of the Holders all
money held by it as Paying Agent.  Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent
for the Securities.

SECTION  2.5.    HOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders and shall otherwise comply with TIA Section  312(a).  If



                                      24

<PAGE>   31
the Trustee is not the Registrar, the Company shall furnish or cause to be
furnished to the Trustee at least ten Business Days prior to each interest
payment date, and at such other times as the Trustee may request in writing, a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Holders, and the Company shall otherwise comply with
TIA Section  312(a).

SECTION  2.6.    TRANSFER AND EXCHANGE.

         (a)     Transfer and Exchange of Global Notes.  The transfer and
exchange of Global Notes or beneficial interests therein shall be effected
through the Depository, in accordance with this Indenture and the Applicable
Procedures.  Beneficial interests in a Global Note may be transferred to
Persons who take delivery thereof in the form of a beneficial interest in the
same Global Note in accordance with the Applicable Procedures and, in the case
of a Transfer Restricted Security, the transfer restrictions set forth in the
legend in Section 2.6(f). Transfers of beneficial interests in the Global Notes
to Persons required to take delivery thereof in the form of an interest in
another Global Note shall be permitted as follows:

                 (i)      144A Global Note to Regulation S Global Note.  If, at
         any time, an owner of a beneficial interest in a 144A Global Note
         deposited with the Depository (or the Trustee as custodian for the
         Depository) wishes to transfer its beneficial interest in such 144A
         Global Note to a Person who is required or permitted to take delivery
         thereof in the form of an interest in a Regulation S Global Note, such
         owner shall, subject to the Applicable Procedures, exchange or cause
         the exchange of such interest for an equivalent beneficial interest in
         a Regulation S Global Note as provided in this Section 2.6(a)(i). Upon
         receipt by the Trustee of (A) instructions given in accordance with
         the Applicable Procedures from a Participant directing the Trustee to
         credit or cause to be credited a beneficial interest in the Regulation
         S Global Note in an amount equal to the beneficial interest in the
         144A Global Note to be transferred, (B) a written order given in
         accordance with the Applicable Procedures containing information

         beneficial interest stating that the transfer of such interest has
         been made in compliance with the transfer restrictions applicable to
         the Global Notes and pursuant to and in accordance with Rule 903 or
         Rule 904 of Regulation S, then the Trustee, as Registrar, shall
         instruct the Depository to reduce or cause to be reduced the aggregate
         principal amount of the applicable 144A Global Note and to increase or
         cause to be increased the aggregate principal amount of the applicable
         Regulation S Global Note by the principal amount of the beneficial
         interest in the 144A Global Note to be transferred, to credit or cause
         to be credited to the account of the Person specified in such
         instructions, a beneficial interest in the Regulation S Global Note
         equal to the reduction in the aggregate principal amount of the 144A
         Global Note, and to debit, or cause to be debited, from the account of
         the Person making such transfer the beneficial interest in the 144A
         Global Note that is being transferred.

                 (ii)     Regulation S Global Note to 144A Global Note.  If, at
         any time, after the expiration of the 40- day restricted period, an
         owner of a beneficial interest in a Regulation S Global Note deposited
         with the Depository (or with the Trustee as custodian for the
         Depository) wishes to transfer its beneficial interest in such
         Regulation S Global Note to a Person who is required or permitted to
         take delivery thereof in the form of an interest in a 144A Global
         Note, such owner shall, subject to the Applicable Procedures, exchange
         or cause the exchange of such interest for an equivalent beneficial
         interest in a 144A Global Note as provided in this Section 2.6(a)(ii).
         Upon receipt by the Trustee of (A) instructions from Euroclear or
         Cedel, if applicable, and the Depository, directing the Trustee, as
         Registrar, to credit or cause to be credited a beneficial interest in

<PAGE>   32
         Regulation S Global Note to be transferred, such instructions to

         (C) a certificate in the form of Exhibit B-2 attached hereto given by
         the owner of such beneficial interest stating (1) if the transfer is
         pursuant to Rule 144A, that the Person transferring such interest in a
         Regulation S Global Note reasonably believes that the Person acquiring
         such interest in a 144A Global Note is a QIB and is obtaining such
         beneficial interest in a transaction meeting the requirements of Rule
         144A, (2) that the transfer complies with the requirements of Rule 144
         under the Securities Act, (3) if the transfer is pursuant to any other
         exemption from the registration requirements of the Securities Act,
         that the transfer of such interest has been made in compliance with
         the transfer restrictions applicable to the Global Notes and pursuant
         to and in accordance with the requirements of the exemption claimed,

         transferee or the transferor in form reasonably acceptable to the
         Company and to the Registrar and in each case of clause (1), (2) or
         (3) of this Section 2.6(a)(ii), in accordance with any applicable
         securities laws of any state of the United States or any other
         applicable jurisdiction or (4) such transfer is being effected
         pursuant to an effective registration statement under the Securities
         Act, then the Trustee, as Registrar, shall instruct the Depository to

         Regulation S Global Note and to increase or cause to be increased the
         aggregate principal amount of the applicable 144A Global Note by the
         principal amount of the beneficial interest in the Regulation S Global
         Note to be transferred, and the Trustee, as Registrar, shall instruct
         the Depository, concurrently with such reduction, to credit or cause
         to be credited to the account of the Person specified in such
         instructions a beneficial interest in the applicable 144A Global Note
         equal to the reduction in the aggregate principal amount of such
         Regulation S Global Note and to debit or cause to be debited from the
         account of the Person making such transfer the beneficial interest in
         the Regulation S Global Note that is being transferred.

                          exemption from registration in accordance with Rule
                          144 under the Securities Act or pursuant to an

                          is being transferred to an Institutional Accredited
                          Investor in reliance on an exemption from the
                          registration requirements of the Securities Act other
                          than those listed in subparagraph (2) or (3) above, a

                          States; and

                          (B)     in the case of Unrestricted Definitive
                 Securities, a Holder thereof may transfer such Securities to a
                 Person who takes delivery thereof in the form of an
                 Unrestricted Definitive Security, and upon receipt of a

                 acquired the Security in an offshore transaction that was in
                 compliance with Regulation S, or if such Holder is
                 transferring same, that such transfer was made pursuant to an

         (c)     Transfer of a Beneficial Interest in a 144A Global Note or
Regulation S Permanent Global Note for a Definitive Security.

                 (i)      Any Person having a beneficial interest in a 144A
         Global Note or Regulation S Permanent Global Note may upon request,
         subject to the Applicable Procedures, exchange such beneficial

                 accordance with Rule 904 under the Securities Act, a
                 certification to that effect from the transferor (in

                 transferred to an Institutional Accredited Investor, pursuant
                 to a private placement exemption from the registration

                 such transfer is in compliance with the Securities Act and any
                 applicable blue sky laws of any state of the United States.

         in which case the Trustee or the Securities Custodian, at the
         direction of the Trustee, shall, in accordance with the standing
         instructions and procedures existing between the Depository and the
         Securities Custodian, cause the aggregate principal amount of 144A
         Global Notes or Regulation S Permanent Global Notes, as applicable, to
         be reduced accordingly and, following such reduction, the Company
         shall execute and, the Trustee shall authenticate and deliver to the
         transferee a Definitive Security in the appropriate principal amount.

                 (ii)     Definitive Securities issued in exchange for a
         beneficial interest in a 144A Global Note or Regulation S Permanent
         Global Note, as applicable, pursuant to this Section 2.6(c) shall be
         registered in such names and in such authorized denominations as the
         Depository, pursuant to instructions from its direct or Indirect
         Participants or otherwise, shall instruct the Trustee.  The Trustee
         shall deliver such Definitive Securities to the Persons in whose names
         such Securities are so registered.  Following any such issuance of
         Definitive Securities, the Trustee, as Registrar, shall instruct the
         Depository to reduce or cause to be reduced the aggregate principal
         amount of the applicable Global Note to reflect the transfer.

         (d)     Restrictions on Transfer and Exchange of Global Notes.
Notwithstanding any other provision of this Indenture (other than the
provisions set forth in Section 2.6(f)), a Global Note may not be transferred
as a whole except by the Depository to a nominee of the Depository or by a
nominee of the Depository to the Depository or another nominee of the
Depository or by the Depository or any such nominee to a successor Depository
or a nominee of such successor Depository.

         (e)     Authentication of Definitive Securities in Absence of
Depository or Company's Election.  If at any time (i) the Depository for the
Securities notifies the Company that the Depository is unwilling or unable to
continue as Depository for the Global Notes and a successor Depository for the
Global Notes is not appointed by the Company within 90 days after delivery of
such notice, and the Trustee is notified in writing of the foregoing by the
Company, or (ii) the Company, at its option, notifies the Trustee in writing
that it elects to cause issuance of Securities in the form of Definitive
Securities under the Indenture, then upon surrender by the Holders of Global
Notes, the Company shall execute, and the Trustee shall, upon receipt of an
authentication order in accordance with Section 2.2, authenticate and deliver,
Definitive Securities in an aggregate principal amount equal to the principal
amount of the Global Notes in exchange for such Global Notes.

         (f)     Legends.

                 (i)      Except as permitted by the following paragraphs (ii),
         (iii) and (iv), each Security certificate evidencing a Global Note or
         a Definitive Security (and all Securities issued in exchange therefor
         or substitution thereof) shall bear a legend in substantially the
         following form:

                 (ii)     Upon any sale or transfer of a Transfer Restricted
         Security (including any Transfer Restricted Security represented by a
         Global Note) pursuant to Rule 144 under the Securities Act or pursuant
         to an effective registration statement under the Securities Act
         (including an Effective Registration involving the Notes Registration
         Statement):

                          (A)     in the case of any Transfer Restricted
                 Security that is a Definitive Security, the Registrar shall
                 permit the Holder thereof to exchange such Transfer Restricted
                 Security for a Definitive Security that does not bear the
                 Restrictive Legend and

                 Restricted Security upon certification from the transferring
                 holder substantially in the form of Exhibit B-3; and

                          (B)     in the case of any Transfer Restricted
                 Security represented by a Global Note, such Transfer
                 Restricted Security shall not be required to bear the
                 Restrictive Legend, but shall continue to be subject to the
                 provisions of Sections 2.6(a) and (c) hereof; provided,
                 however, that with respect to any request for an exchange of a
                 Transfer Restricted Security that is represented by a Global
                 Note for a Definitive Security that does not bear the
                 Restrictive Legend, which request is made in reliance upon
                 Rule 144 or pursuant to an effective registration statement,
                 the Holder thereof shall certify in writing to the Registrar

                 pursuant to an effective registration statement (such
                 certification to be substantially in the form of Exhibit B-4).

                 (iii)    Upon any sale or transfer of a Transfer Restricted
         Security (including any Transfer Restricted Security represented by a
         Global Note) in reliance on any exemption from the registration
         requirements of the Securities Act (other than exemptions pursuant to
         Rule 144 under the Securities Act) in which the Holder or the
         transferee provides an Opinion of Counsel to the Company and the
         Registrar in form and substance reasonably acceptable to the Company
         and the Registrar (which Opinion of Counsel shall also state that the
         transfer restrictions contained in the legend are no longer
         applicable):

                          (A)     in the case of any Transfer Restricted
                 Security that is a Definitive Security, the Registrar shall
                 permit the Holder thereof to exchange such Transfer Restricted
                 Security for a Definitive Security that does not bear the
                 Restrictive Legend and rescind any restriction on the transfer
                 of such Transfer Restricted Security; and

                          (B)     in the case of any Transfer Restricted
                 Security represented by a Global Note, such Transfer
                 Restricted Security shall not be required to bear the
                 Restrictive Legend, but shall continue to be subject to the
                 provisions of Sections 2.6(a) and (c).

                 (iv)     Notwithstanding the foregoing, upon consummation of
         an Exchange Offer, the Company shall issue and, upon receipt of an
         authentication order in accordance with Section 2.2, the Trustee shall
         authenticate one or more Unrestricted Global Notes in aggregate
         principal amount equal to the sum of (A) the principal amount of the
         Restricted Beneficial Interests tendered for acceptance by Persons
         that are not (1) broker-dealers, (2) Persons participating in the
         distribution of the Series B Notes or (3) Persons who are affiliates
         (as defined in Rule 144) of the Company and accepted for exchange in
         the Exchange Offer and (B) the principal amount of the Restricted
         Definitive Securities accepted for exchange in the Exchange Offer,
         unless the Holders of such Restricted Definitive Securities shall
         request the receipt of Definitive Securities, in which case the
         Company shall execute and the Trustee shall authenticate and deliver
         to the Persons designated by the Holders of such Restricted Definitive
         Securities one or more Definitive Securities without the Restrictive
         Legend in the appropriate principal amount.  Concurrently with the
         issuance of such Unrestricted Global Notes, the Trustee shall cause
         the aggregate principal amount of the applicable Restricted Global
         Notes to be reduced accordingly.

         (g)     Cancellation and/or Adjustment of Global Notes.  At such time
as all beneficial interests in Global Notes have been exchanged for Definitive
Securities, redeemed, repurchased or cancelled, all Global Notes shall be
returned to or retained and cancelled by the Trustee in accordance with Section
2.11.  At any time prior to such cancellation, if any beneficial interest in a
Global Note is


                                      31



<PAGE>   38
exchanged for Definitive Securities, redeemed, repurchased or cancelled, the
principal amount of Securities represented by such Global Note shall be reduced
accordingly and an endorsement shall be made on such Global Note, by the
Trustee or the Securities Custodian, at the direction of the Trustee, to
reflect such reduction.

         (h)     General Provisions Relating to Transfers and Exchanges.

                 (i)      To permit registrations of transfers and exchanges,
         subject to this Section 2.6, the Company shall execute and, upon the
         written order of the Company signed by two Officers of the Company,
         the Trustee shall authenticate Definitive Securities and Global Notes
         at the Registrar's request.

                 (ii)     No service charge shall be made to a Holder for any
         registration of transfer or exchange, but the Company may require
         payment of a sum sufficient to cover any transfer tax or similar
         governmental charge payable in connection therewith (other than any
         such transfer taxes or similar governmental charge payable upon
         exchange or transfer pursuant to Sections 3.7, 4.11, 4.17 and 9.5).

                 (iii)    The Registrar shall not be required to register the
         transfer of or exchange any Security selected for redemption in whole
         or in part, except the unredeemed portion of any Security being
         redeemed in part.

                 (iv)     All Definitive Securities and Global Notes issued
         upon any registration of transfer or exchange of Definitive Securities
         or Global Notes shall be the valid obligations of the Company,
         evidencing the same debt, and entitled to the same benefits under this
         Indenture, as the Definitive Securities or Global Notes surrendered
         upon such registration of transfer or exchange.

                 (v)      The Company and the Registrar shall not be required:

                          (A)     to issue, to register the transfer of or to
                 exchange Securities during a period beginning at the opening
                 of business 15 days before the day of any selection of
                 Securities for redemption under Section 3.2 and ending at the
                 close of business on the day of selection;

                          (B)     to register the transfer of or to exchange
                 any Security so selected for redemption in whole or in part,
                 except the unredeemed portion of any Security being redeemed
                 in part;

                          (C)     to register the transfer of or to exchange a
                 Security between a record date and the next succeeding
                 interest payment date; or

                          (D)     to register the transfer of a Security other
                 than in amounts of $1,000 or multiple integrals thereof.

                 (vi)     Prior to due presentment for the registration of a
         transfer of any Security, the Trustee, any Agent and the Company may
         deem and treat the Person in whose name any Security is registered as
         the absolute owner of such Security for the purpose of receiving
         payment of principal of and interest on such Securities, and neither
         the Trustee, any Agent nor the Company shall be affected by notice to
         the contrary.




                                      32
<PAGE>   39
                 (vii)    The Trustee shall authenticate Definitive Securities
         and Global Notes in accordance with the provisions of Section 2.2.

SECTION  2.7.    REPLACEMENT SECURITIES.

         If a mutilated Security is surrendered to the Trustee or if a Holder
claims, and the Trustee receives evidence to its satisfaction, that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee, upon written order of the Company signed by two Officers of
the Company, shall authenticate a replacement Security if the requirements of
the Trustee are met.  An indemnity bond may be required by the Trustee or the
Company that is sufficient in the judgment of the Company and the Trustee to
protect the Company, the Guarantors, the Trustee or any Agent from any loss
which any of them may suffer if a Security is replaced.  The Company may charge
for its expenses (including fees and expenses of the Trustee) in replacing a
Security.  If, after the delivery of such replacement Security, a bona fide
purchaser of the original Security in lieu of which such replacement Security
was issued presents for payment or registration such original Security, the
Trustee shall be entitled to recover such replacement Security from the Person
to whom it was delivered or any Person taking therefrom, except a bona fide
purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred
by the Company, any Guarantor, the Trustee or any Agent in connection
therewith.

         Subject to the provisions of the final sentence of the preceding
paragraph of this Section 2.7, every replacement Security is an additional
obligation of the Company and shall be entitled to all of the benefits of this
Indenture equally and proportionately with all other Securities duly issued
hereunder.

SECTION  2.8.    OUTSTANDING SECURITIES.

         Securities outstanding at any time are all Securities authenticated by
the Trustee except for those cancelled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section 2.8 as not outstanding.  Except as set forth in Section 2.9, a Security
does not cease to be outstanding because the Company, the Guarantors or any of
their respective Subsidiaries or Affiliates holds the Security.

         If a Security is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

         If the entire principal of, and premium, interest and Liquidated
Damages, if any, on, any Security are considered paid under Section 4.1, it
ceases to be outstanding and interest and Liquidated Damages, if any, on it
cease to accrue.

         If the Paying Agent (other than the Company, a Subsidiary of the
Company or an Affiliate of any thereof) holds, on a redemption date or maturity
date, money sufficient fully to pay Securities payable on that date, then on
and after that date such Securities shall be deemed to be no longer outstanding
and shall cease to accrue interest and Liquidated Damages, if any.

SECTION  2.9.    TREASURY SECURITIES.

         In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company, any Guarantor or an Affiliate of the Company shall be
considered as though they are not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent,




                                      33


<PAGE>   40
only Securities that the Trustee knows are so owned shall be so disregarded.
Notwithstanding the foregoing, Securities that the Company, a Subsidiary of the
Company or an Affiliate of the Company offers to purchase or acquire pursuant
to an offer, exchange offer, tender offer or otherwise shall not be deemed to
be owned by the Company, any Guarantor or an Affiliate of the Company until
legal title to such Securities passes to the Company, such Guarantor or such
Affiliate, as the case may be.

SECTION  2.10.   TEMPORARY SECURITIES.

         Until definitive Securities are ready for delivery, the Company may
prepare and, upon written order of the Company signed by two Officers of the
Company, the Trustee shall authenticate temporary Securities.  Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities
and as shall be reasonably acceptable to the Trustee.  Without unreasonable
delay, the Company shall prepare and the Trustee shall authenticate and deliver
definitive Securities in exchange for a like principal amount of temporary
Securities surrendered to it.  Until so exchanged, Holders of temporary
Securities shall in all respects be entitled to all benefits of this Indenture.

SECTION  2.11.   CANCELLATION.

         The Company at any time may deliver Securities to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment.  The Trustee, and no one else, shall cancel all Securities surrendered
for registration of transfer, exchange, payment, replacement or cancellation
and, at the written request of the Company, shall destroy cancelled Securities
(subject to the record retention requirements of the Exchange Act).  Except as
provided in Section 2.7, the Company may not issue new Securities to replace
Securities that it has paid or delivered to the Trustee for cancellation, other
than as contemplated by the Exchange Offer.

         Securities that are redeemed by the Company, that are repurchased by
the Company pursuant to Section 4.11 or Section 4.17, or that are otherwise
acquired by the Company, shall be surrendered to the Trustee for cancellation.

SECTION  2.12    DEFAULTED INTEREST.

         If the Company defaults in a payment of interest on the Securities, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest (taken together, the
"DEFAULTED INTEREST"), to the Persons who are Holders on a subsequent special
record date, in each case at the rate provided in the Securities and in Section
4.1 hereof.  The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Security and the date of
proposed payment.  At least 15 days before the special record date, the Company
shall mail to each Holder to be paid thereon a notice stating the special
record date, the payment date and the amount of Defaulted Interest to be paid.
In the event that the Company has elected to cause a Paying Agent to pay the
Defaulted Interest, the Company shall so notify the Paying Agent at least 15
days before the special record date, which notice shall also set forth the
special record date, the payment date and the aggregate amount of Defaulted
Interest to be paid.  At least five days before such payment date, the Company
shall deposit with the Paying Agent money sufficient to pay all of the
Defaulted Interest on the payment date therefor and instruct the Paying Agent
in writing to pay to specified Holders on the payment date.  On the payment
date, the Paying Agent shall make the payments in accordance with the Company's
written instructions from funds deposited with the Paying Agent for the purpose
of making such Defaulted Interest payments.

SECTION  2.13.   PERSONS DEEMED OWNERS.

         The Company, the Trustee, any Paying Agent and any authenticating
agent may treat the Person in whose name any Security is registered as the
owner of such Security for the purpose of receiving payments of principal of,
or premium, if any, interest or Liquidated Damages, if any, on, such Security
and for all other purposes.  None of the Company, the Trustee, any Paying Agent
or any authenticating agent shall be affected by any notice to the contrary.

                                  ARTICLE III

                                   REDEMPTION

SECTION  3.1.    NOTICE TO TRUSTEE.

         If the Company elects to redeem Securities pursuant to the optional
redemption provisions of paragraph 5 of the Securities, it shall furnish to the
Trustee and the Registrar, at least 45 days but not more than 60 days before
the redemption date (unless the Trustee consents to a shorter period in
writing), an Officers' Certificate setting forth the redemption date, the
principal amount of Securities to be redeemed and the redemption price.

SECTION  3.2.    SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all of the Securities are to be redeemed at any time, the
Trustee shall select the Securities to be redeemed in compliance with the
requirements of the principal national securities exchange, if any, on which the
Securities are listed, or if the Securities 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 Securities with a principal amount of $1,000 or
less will be redeemed in part.  The Trustee shall make the selection from
outstanding Securities not previously called for redemption not less than 30 nor
more than 60 days prior to the redemption date.  The Trustee may select for
redemption portions of the principal of Securities that have denominations
larger than $1,000.  Securities and portions of them it selects shall be in
amounts of $1,000 or whole multiples of $1,000.  Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of
Securities called for redemption. The Trustee shall notify the Company promptly
of the Securities or portions of Securities selected for redemption.

SECTION  3.3.    NOTICE OF REDEMPTION.

         (a)     At least 30 days but not more than 60 days before the date
fixed for redemption, the Company shall mail a notice of redemption by
first-class mail to each Holder of Securities to be redeemed at such Holder's
registered address.

         The notice shall identify the Securities to be redeemed and shall
state:

                 (1)      the redemption date;

                 (2)      the redemption price;

                 (3)      the aggregate principal amount of Securities being
         redeemed;

                 (4)      the name and address of the Paying Agent;



                                      35

<PAGE>   42
                 (5)      that Securities called for redemption must be
         surrendered to the Paying Agent at the address specified in such
         notice to collect the redemption price;

                 (6)      that, unless the Company defaults in the payment of
         the redemption price or accrued interest or Liquidated Damages, if
         any, interest and Liquidated Damages, if any, on Securities called for
         redemption ceases to accrue on and after the redemption date, and the
         only remaining right of the Holders is to receive payment of the
         redemption prices in respect of the Securities upon surrender to the
         Paying Agent of the Securities;

                 (7)      if any Security is being redeemed in part, the
         portion of the principal amount of such Security to be redeemed and
         that, after the redemption date, upon surrender of such Security, a
         new Security or Securities in principal amount equal to the unredeemed
         portion will be issued;

                 (8)      the paragraph of the Securities pursuant to which the
         Securities called for redemption are being redeemed; and

                 (9)      the CUSIP number of the Securities.

         (b)     At the Company's request, the Trustee shall give the notice of
redemption required in Section 3.3(a) in the Company's name and at the
Company's expense; provided, however, that the Company shall deliver to the
Trustee, at least 45 days prior to the redemption date (unless the Trustee
consents to a shorter notice period in writing), an Officers' Certificate
requesting that the Trustee give such notice and setting forth the information
to be stated in such notice as provided in Section 3.3(a).

SECTION  3.4.    EFFECT OF NOTICE OF REDEMPTION.

         Once notice of redemption is mailed in accordance with Section 3.3,
Securities called for redemption become due and payable on the redemption date
at the redemption price.  A notice of redemption may not be conditional.  Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price, plus accrued interest and Liquidated Damages, if any, to the redemption
date.

SECTION  3.5.    DEPOSIT OF REDEMPTION PRICE.

         At least one Business Day prior to the redemption date, the Company
shall deposit with the Paying Agent (or if the Company or any of its Affiliates
is acting as the Company's Paying Agent, segregate and hold in trust as
provided in Section 2.4) money available on the redemption date sufficient to
pay the redemption price of, and accrued interest and Liquidated Damages, if
any, on, the Securities to be redeemed on that date.  The Paying Agent shall
promptly return to the Company any money so deposited which is not required for
that purpose upon the written request of the Company, except with respect to
monies owed as obligations to the Trustee pursuant to Article VII.

         If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest and Liquidated Damages,
if any, shall cease to accrue on the Securities or the portions of Securities
called for redemption.  If a Security is redeemed on or after an interest
record date but on or prior to the related interest payment date, then any
accrued and unpaid interest and Liquidated Damages, if any, shall be paid to
the Person in whose name such Security was registered at the close of business
on such record date.  If any Security called for redemption shall not be so
paid upon redemption because of the failure of the Company to comply with the
preceding paragraph, interest and Liquidated Damages, if any, will continue to
be payable on the unpaid principal and premium, if any, including from



                                      36

<PAGE>   43
the redemption date until such principal and premium, if any, is paid, and, to
the extent lawful, on any interest and Liquidated Damages not paid on such
unpaid principal, in each case at the rate provided in the Securities and in
Section 4.1.

SECTION  3.6.    SECURITIES REDEEMED IN PART.

         Upon surrender of a Security that is to be redeemed in part, the
Company shall issue and the Trustee shall authenticate for the Holder, at the
expense of the Company, a new Security equal in aggregate amount to the
unredeemed portion of the Security surrendered.

SECTION  3.7.    OPTIONAL REDEMPTION.

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

         Notwithstanding the provisions of Section 3.7, prior to April 1, 2001,
the Company may redeem up to 30% of the aggregate principal amount of the
Securities originally issued at a redemption price of 111.5% of the aggregate
principal amount of the Securities so redeemed, plus accrued and unpaid
interest and Liquidated Damages, if any, on the Securities so redeemed to the
date of redemption, with all or a portion of the aggregate net proceeds
received by the Company from one or more Equity Offerings; provided that (i) at
least 65% of the aggregate principal amount of the Securities originally issued
remains 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 of each such Equity Offering.

         Any redemption pursuant to this Section 3.8 shall be made pursuant to
the provisions of Section 3.1 through 3.6.

SECTION  4.1.    PAYMENT OF SECURITIES.

         The Company shall pay the principal of, and premium, if any, interest
and Liquidated Damages, if any, on, the Securities on the dates and in the
manner provided in the Securities and this Indenture.  Principal, premium,
interest and Liquidated Damages, if any, shall be considered paid on the date

holds as of 10:00 a.m. New York time on the due date money deposited by the
Company designated for and sufficient to pay all principal, premium, interest
and Liquidated Damages, if any, then due.

         The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal, and premium, if
any, at the rate borne by the Securities to the extent lawful; and it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if
any, (without regard to any applicable grace period) at the same rate to the

SECTION  4.2.    SEC REPORTS.

         (a)     The Company, within 15 days after it files the same with the
SEC, shall deliver to Holders, copies of the annual reports and the
information, documents and other reports (or copies of any such portions of any
of the foregoing as the SEC may by rules and regulations prescribe) that the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act.  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 shall file with the SEC (if the SEC will so accept) and
provide the Trustee and the Holders with such quarterly and annual reports and
such information, documents and other reports specified in Sections 13 and
15(d) of the Exchange Act, including a "Management's Discussion and Analysis of
Financial Condition and Results of Operation", and with respect to the annual

provisions of TIA Section  314(a).

         (b)     The Company may request the Trustee on behalf of the Company
at the Company's expense to mail the foregoing to Holders.  In such case, the
Company shall timely provide the Trustee with a sufficient number of copies of

the end of each fiscal year of the Company, an Officers' Certificate
substantially in the form of Exhibit E,  stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year

further



                                      38

<PAGE>   45
stating, as to each such Officer signing such certificate, that, to the best of
such Officer's knowledge, the Company and each Guarantor has kept, observed,
performed and fulfilled each and every covenant contained in this Indenture and
is not in default in the performance or observance of any of the terms,
provisions and conditions hereof (or, if a Default or Event of Default shall
have occurred, describing all such Defaults or Events of Default of which such
Officer may have knowledge and what action the Company is taking or proposes to
take with respect thereto), and that to the best of such Officers' knowledge,
no event has occurred and remains in existence by reason of which payments on
account of the principal of, or premium, if any, interest and Liquidated
Damages, if any, on, the Securities is prohibited or if such event has
occurred, a description of the event and what action the Company is taking or
proposes to take with respect thereto.  Such Officers' Certificate shall comply

fiscal year.

         (b)     So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.2(a) shall be accompanied by a
written statement of the Company's certified independent public accountants
(which shall be a firm of established national reputation) that in making the
examination necessary for certification of such financial statements, nothing
has come to their attention that would lead them to believe that the Company
has violated any provisions of Article IV or Article V or, if any such
violation has occurred, specifying the nature and period of existence thereof.
Where such financial statements are not accompanied by such a written
statement, the Company shall furnish the Trustee with an Officers' Certificate
stating that any such written statement would be contrary to the then current
recommendations of the American Institute of Certified Public Accountants.

         (c)     The Company and the Guarantors shall, so long as any of the
Securities are outstanding, deliver to the Trustee within 5 Business Days of

performance of any covenant, agreement or condition contained in this
Indenture, an Officers' Certificate specifying such Default or Event of Default
and what action the Company or any Guarantor proposes to take with respect
thereto.

SECTION  4.4.    MAINTENANCE OF OFFICE OR AGENCY.

                 The Company shall maintain in the Borough of Manhattan, The
City of New York, an office or agency where Securities may be presented or
surrendered for payment, where Securities may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served.  Initially, such
office or agency will be State Street Bank & Trust Company of New York, N.A.,
61 Broadway, 15th Floor, New York, New York 10006, and the Company shall give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at such office of the agent of the Trustee, and
the Company hereby appoints such agent of the Trustee as its agent to receive
all such presentations, surrenders, notices and demand.

         Subject to Section 2.3, the Company may also from time to time
designate one or more other offices or agencies where the Securities may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in the Borough of Manhattan, The City of New York, for such purposes.
The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other




                                      39
<PAGE>   46
office or agency.  The Company hereby designates the address of the Trustee set
forth in Section 11.2 (the "CORPORATE TRUST OFFICE") as one of such other
offices or agencies of the Company in accordance with Section 2.3.

SECTION  4.5.    CORPORATE EXISTENCE.

         Subject to Section 5.1 and Section 10.2, the Company will do or cause
to be done all things necessary to preserve and keep in full force and effect
its corporate existence and the corporate, partnership or other existence of
each of its Subsidiary and all rights (charter and statutory) and franchises of
the Company and its Subsidiaries; provided, that the Company shall not be
required to preserve the corporate existence of any Subsidiary, or any such
right or franchise, if the Board of Directors of the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and of the Company and its Subsidiaries taken as a
whole, and that the loss thereof is not, and foreseeably will not be, adverse
to the timely payment and performance of the obligations under the Securities
and otherwise under this Indenture, or otherwise disadvantageous in any other
material respect to the Holders.

SECTION  4.6.    WAIVER OF STAY, EXTENSION OR USURY LAWS.

         Each of the Company and the Guarantors covenants (to the extent that
each may lawfully do so) that it shall not at any time insist upon, plead, or
in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension, or usury law or other law, which would prohibit or forgive the
Company or any Guarantor from paying all or any portion of the principal of, or
premium, if any, interest or Liquidated Damages, if any, on, the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force,
or which may affect the covenants or the timely and complete performance of
this Indenture; and (to the extent that it may lawfully do so) each of the
Company and the Guarantors hereby expressly waives all benefit or advantage of
any such law, and covenants that it shall not, by resort to any such law or
otherwise, hinder, delay or impede the execution of any power herein granted to
the Trustee, but shall suffer and permit the execution of every such power as
though no such law had been enacted.

SECTION  4.7.    PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company shall pay or discharge, and shall cause each of its
Subsidiaries to pay and discharge, before the same shall become delinquent, (a)
all taxes, assessments and governmental charges levied or imposed upon the
Company or any such Subsidiary or upon the income, profits or property of the
Company or any such Subsidiary and (b) all lawful claims for labor, materials
and supplies which, if unpaid, might by law become a Lien upon the property of
the Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
diligently contested in good faith by appropriate proceedings.

SECTION  4.8.    MAINTENANCE OF PROPERTIES AND INSURANCE.

         (a)     The Company shall cause all properties used or held for use in
the conduct of its business or the business of any Subsidiary to be maintained
and kept in good condition, repair and working order (ordinary wear and tear
excepted) and supplied with all necessary equipment and shall cause to be made
all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that there
is no material adverse effect to the Company and its Subsidiaries, taken as a
whole; provided, however, that nothing in this Section shall prevent the



                                      40

<PAGE>   47
Company from discontinuing the operation or maintenance of any such property,
or abandoning or disposing of it, if such discontinuance, abandonment or
disposal is, in the judgment of the Board of Directors of the Company,
desirable in the conduct of its business and of the business of it and its
Subsidiaries taken as a whole and not adverse to the timely payment and
performance of the obligations under this Indenture or otherwise
disadvantageous in any other material respect to the Holders.

         (b)     The Company shall provide or cause to be provided, for itself
and each of its Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds that, in the reasonable, good faith opinion
of the Company, are adequate and appropriate for the conduct of the business of
the Company and such Subsidiaries in a prudent manner, with reputable insurers
or with the government of the United States or an agency or instrumentality
thereof, in such amounts, with such deductibles, and by such methods as shall
be customary, in the reasonable, good faith opinion of the Company, for
corporations similarly situated in the industry.

SECTION  4.9.    LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS.

         (a)     The Company shall not, and shall 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.

         (b)     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.  For the avoidance of doubt,
neither the Company nor any of its Restricted Subsidiaries may incur Permitted
Indebtedness if a Default or Event of Default shall have occurred and is then
continuing or as a consequence of the incurrence of such Indebtedness, a
Default or Event of Default occurs.

         (c)     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.

         (d)     Notwithstanding the preceding paragraphs of this Section 4.9,
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 Securities 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 this Indenture.

Payment, unless:

                 (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 Section 4.9(a); 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

                 (less the aggregate amount of dividends described in clause
                 (i) of Section 4.10(b) 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 Board
                 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 (which amount, for purposes of
                 this clause (iii), shall be stated as a negative number).

         (b)     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 this 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 Section 4.10(a); 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, as amended and in effect from time to
time, provided that the funds or value expended or incurred, or committed to be
expended or incurred, in each fiscal year of the Company does 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.

         (c)     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 Board 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 this Section 4.10 were computed.

SECTION  4.11.   LIMITATION ON SALE OF ASSETS.

         (a)     The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, make any Asset Sale unless:



                                      43

<PAGE>   50
                 (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 $5,000,000 shall be evidenced by a Board
         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 Section 4.11(b) and Section 4.11(c).

         (b)     The Company may apply such Net Cash Proceeds, within 365 days
after receipt of Net Cash Proceeds from any Asset Sale, to: (i) 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; (ii) 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 (iii)
develop by drilling, completing and producing reserves from the oil and gas
properties of the Company and the Restricted Subsidiaries.

         (c)     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 Section 4.11(b), 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 $5,000,000, then the Company shall be
required to commence, and within 10 Business Days following such occurrence,
shall commence, an offer (the "NET PROCEEDS OFFER") to repurchase the
Securities (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 Securities 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 Securities 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.

         (d)     In the event that pursuant to the above provisions of this
Section 4.11 the Company is required to commence a Net Proceeds Offer, it shall
follow the procedures specified below:

                 (i)      The Net Proceeds Offer shall remain open for a period
         of 20 Business Days following its commencement and no longer, except
         to the extent that a longer period is required by applicable law (the
         "OFFER PERIOD").  No later than five Business Days after the
         termination of the Offer Period (the "PURCHASE DATE"), the Company
         shall purchase the principal amount of Securities required to be
         purchased pursuant to Section 4.11(c) (the "OFFER AMOUNT") or, if less
         than the Offer Amount has been tendered, all Securities validly
         tendered in response to the Net


                                      44


<PAGE>   51
         Proceeds Offer.  Payment for any Securities so purchased shall be made
         in the same manner as interest payments are made.

                 (ii)     If the Purchase Date is on or after an interest
         record date and on or before the related interest payment date, any
         accrued and unpaid interest and Liquidated Damages, if any, shall be
         paid to the Person in whose name a Security is registered at the close
         of business on such record date, and no additional interest or
         Liquidated Damages, if any, shall be payable to Holders who tender
         Securities pursuant to the Net Proceeds Offer.

                 (iii)    Upon the commencement of a Net Proceeds Offer, the
         Company shall send, by first class mail, a notice to each of the
         Holders, with a copy to the Trustee.  The notice shall contain all
         instructions and materials necessary to enable such Holders to tender
         Securities pursuant to the Net Proceeds Offer.  The Net Proceeds Offer
         shall be made to all Holders.  The notice, which shall govern the
         terms of the Net Proceeds Offer, shall state:

                          (A)     that the Net Proceeds Offer is being made
                 pursuant to this Section 4.11 and the length of time the Net
                 Proceeds Offer shall remain open;

                          (B)     the Offer Amount, the purchase price and the
                 Purchase Date;

                          (C)     that any Security not tendered or accepted
                 for payment shall continue to accrue interest and Liquidated
                 Damages, if any;

                          (D)     that, unless the Company defaults in making
                 such payment, any Security accepted for payment pursuant to
                 the Net Proceeds Offer shall cease to accrue interest and
                 Liquidated Damages, if any, after the Purchase Date;

                          (E)     that Holders electing to have a Security
                 purchased pursuant to a Net Proceeds Offer may only elect to
                 have all of such Security purchased and may not elect to have
                 only a portion of such Security purchased;

                          (F)     that Holders electing to have a Security
                 purchased pursuant to any Net Proceeds Offer shall be required
                 to surrender the Security, with the form entitled "Option of
                 Holder to Elect Purchase" on the reverse of the Security
                 completed, to the Company or a Paying Agent at the address
                 specified in the notice at least three days before the
                 Purchase Date;

                          (G)     that Holders shall be entitled to withdraw
                 their election if the Company or the Paying Agent, as the case
                 may be, receives, not later than the expiration of the Offer
                 Period, a telegram, telex, facsimile transmission or letter
                 setting forth the name of the Holder, the principal amount of
                 the Security the Holder delivered for purchase and a statement
                 that such Holder is withdrawing his election to have such
                 Security purchased;

                          (H)     that, if the aggregate principal amount of
                 Securities surrendered by Holders exceeds the Offer Amount,
                 the Trustee shall select the Securities to be purchased as
                 provided in Section 3.2 (with such adjustments as may be
                 deemed appropriate by the Trustee so that only Securities in
                 denominations of $1,000, or integral multiples thereof, shall
                 be purchased); and




                                      45
<PAGE>   52
                          (I)     that Holders whose Securities were purchased
                 only in part shall be issued new Securities equal in principal
                 amount to the unpurchased portion of the Securities
                 surrendered (or transferred by book-entry transfer).

                 (iv)     If any of the Securities subject to a Net Proceeds
         Offer is in the form of a Global Note, then the Company shall modify
         such notice to the extent necessary to accord with the procedures of
         the Depository applicable to repurchases (including Applicable
         Procedures).

                 (v)      On or before the Purchase Date, the Company shall, to
         the extent lawful, accept for payment, on a pro rata basis to the
         extent necessary, the Offer Amount of Securities or portions thereof
         tendered pursuant to the Net Proceeds Offer, or if less than the Offer
         Amount has been tendered, all Securities tendered, and shall deliver
         to the Trustee an Officers' Certificate stating that such Securities
         or portions thereof were accepted for payment by the Company in
         accordance with the terms of this Section 4.11.  The Company or the
         Paying Agent, as the case may be, shall promptly (but in any case not
         later than five days after the Purchase Date) mail or deliver to each
         tendering Holder an amount equal to the purchase price of the
         Securities tendered by such Holder and accepted by the Company for
         purchase, and the Company shall promptly issue a new Security, and the
         Trustee shall authenticate and mail or deliver such new Security to
         such Holder, in a principal amount equal to any unpurchased portion of
         the Security surrendered.  Any Security not so accepted shall be
         promptly mailed or delivered by the Company to the Holder thereof.
         The Company shall publicly announce the results of the Net Proceeds
         Offer on the Purchase Date.

                 (vi)     Other than as specifically provided in this Section
         4.11, any purchase pursuant to this Section 4.11 shall be made pursuant
         to the provisions of Section 3.1 through Section 3.6.

         (e)     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.

         (f)     During the period between any Asset Sale and the application
of the Net Cash Proceeds therefrom in accordance with this Section 4.11, 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.

         (g)     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.

SECTION  4.12.   LIMITATION ON LIENS SECURING INDEBTEDNESS.

         The Company shall not, and shall 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 Securities 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 Securities or the Guarantees, the Lien securing such Indebtedness will
be subordinated and junior to any Lien securing the Securities or the
Guarantees, with the same relative priority as such




                                      46
<PAGE>   53
Subordinated Indebtedness of the Company or Subordinated Indebtedness of a
Guarantor will have with respect to the Securities or the Guarantees, as the
case may be.

SECTION  4.13.   LIMITATION ON SALE/LEASEBACK TRANSACTIONS.

         The Company shall not, and shall 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 Section 4.9(a)  and (b) incurred a Lien to secure such Indebtedness, without
being required to equally and ratably secure the Securities pursuant to Section
4.12, 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 Board 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, Section 4.11.

SECTION  4.14.   LIMITATION ON PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

         The Company shall not, and shall not permit any of its Restricted

encumbrances or consensual restrictions under any agreement that refinances or
replaces any agreement described in clauses (a) and (b) above, provided that

         The Company (i) shall not permit any Restricted Subsidiary, directly
or indirectly, to issue any Disqualified Stock or Preferred Stock (other than

(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 Section 4.15 shall not prohibit (a)

the Consolidated Total Assets of the Company, and in the case of either clause
(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

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

unrelated Person. In addition, the Company shall not, and shall 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

Liquidated Damages, if any, payable on such interest payment date shall be paid
to the Person in whose name a Security is registered at the close of business
on such record date, and no additional interest or Liquidated Damages, if any,
will be payable to Holders who tender Securities pursuant to the Change of
Control Offer.

Control Offer is being made pursuant to this Section 4.17; (2) the repurchase
price and the Change of Control Payment Date; (3) that any Security not
tendered shall continue to accrue interest and Liquidated Damages, if any, at
the respective stated rates; (4) that any Security accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest and
Liquidated Damages, if any, on the Change of Control Payment Date; (5) that
Holders electing to have a Security repurchased pursuant to any Change of
Control Offer shall be required to surrender the Security, with the form
entitled "Option of Holder to Elect Repurchase" on the reverse of the Security
completed, to the Company, a depositary, if appointed by the Company, or a
Paying Agent at the address specified in the notice prior to termination of the
Change of Control Offer; (6) that Holders shall be entitled to withdraw their
election if the Company, such depositary or Paying Agent, as the case may be,
receives, not later than the expiration of the Change of Control Offer, or such
longer period as may be required by law, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Security the Holder delivered for repurchase and a statement that
such Holder is withdrawing his election to have the Security repurchased; and
(7) that Holders whose Securities are repurchased only in part shall be issued
Securities equal in principal amount to the unrepurchased portion of the
Securities surrendered.

         (c)     On the Change of Control Payment Date, the Company shall, to
the extent lawful, (i) accept for payment Securities or portions thereof
tendered pursuant to the Change of Control Notice, (ii) if the Company appoints
a depositary or Paying Agent, deposit with such depositary or Paying Agent
money sufficient to pay the Change of Control Payment Price in respect of all
Securities or portions thereof so tendered and (iii) deliver to the Trustee the
Securities so accepted together with an Officers' Certificate stating the
aggregate principal amount of the Securities or portions thereof being
purchased by the Company.  Such depositary, the Company or the Paying Agent, as
the case may be, shall promptly mail to the Holders of Securities so accepted
payment in an amount equal to the repurchase price, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book-entry to
each such Holder a new Security equal in principal amount to any unpurchased
portion of the Security surrendered, if any; provided, that each such Security
will be in a principal amount of $1,000 or an integral multiple.  The Company
shall publicly announce the results of the Change of Control Offer on or as
soon as practicable after the Change of Control Payment Date.  For purposes of
this Section 4.17, the Trustee shall act as the Paying Agent.

         (d)     The Company shall comply with Section 14 of the Exchange Act
and the provisions of Regulation 14E and any other tender offer rules under the

         alone would or could result in a material liability) shall occur or
         exist with respect to a PBGC Plan, which in combination with one or
         more of any events described in (i) through (vi) above (determined
         without regard to whether the event or condition taken alone would or

rate or rates prescribed therefor in the Securities, (C) to the extent that
payment of such interest is lawful, interest on the defaulted interest at the
rate or rates prescribed therefor in the Securities, and (D) all money paid or
advanced by the Trustee thereunder and the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel; (2) all
Events of Default, other than the non-payment of the principal of any
Securities that have become due solely by such declaration of acceleration,
have been cured or waived as provided in this Indenture; and (3) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction.  No such rescission will affect any subsequent Event of Default
or impair any right consequent thereon.

SECTION  6.3.    OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may, but
is not obligated to, pursue, in its own name and as trustee of an express
trust, any available remedy by proceeding at law or in equity to collect the
payment of principal or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.  If an Event
of Default specified under clause (11) or clause (12) of Section 6.1 occurs
with respect to the Company at a time when the Company is the Paying Agent, the
Trustee shall automatically assume the duties of Paying Agent.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay
or omission by the Trustee or any Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.

SECTION  6.4.    WAIVER OF PAST DEFAULTS.

         Subject to Sections 6.7 and 9.2, the Holders of at least a majority in
principal amount of Securities then outstanding by notice to the Trustee may
waive an existing Default or Event of Default and its consequences, except a
Default or Event of Default in payment of principal of, or premium, if any,
interest or Liquidated Damages, if any, on the Securities, including any
optional redemption payments or Change of Control or Net Proceeds Offer
payments.

SECTION  6.5.    CONTROL BY MAJORITY.

         The Holders of a majority in principal amount of the Securities then
outstanding shall have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee or
exercising any trust or power conferred on such Trustee, provided that (1) such
direction is not in conflict with any rule of law or with this Indenture and
(2) the Trustee may take any other action deemed proper by such Trustee that is
not inconsistent with such direction.

SECTION  6.6.    LIMITATION ON REMEDIES.

         No Holder of any of the Securities shall have any right to institute
any proceeding, judicial or otherwise, or for the appointment of a receiver or
trustee or pursue any remedy under this Indenture, unless:

                 (1)      the Trustee has previously received written notice of
         a continuing Event of Default from such Holder,

                 (2)      the Trustee has previously received a request from
         Holders of at least 25% in principal amount of the outstanding
         Securities to institute proceedings in respect of such Event of
         Default or to pursue such remedy in its own name as Trustee under the
         Indenture,

                 (3)      such Holder or Holders have offered to such Trustee
         indemnity against the costs, expenses and liabilities to be incurred
         in compliance with such request, which is reasonably satisfactory to
         the Trustee,

                 (4)      the Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity has failed to institute any
         proceeding or otherwise act as requested, and

                 (5)      no direction inconsistent with such written request
         has been given to such Trustee during such 60-day period by the
         Holders of a majority in principal amount of the outstanding
         Securities.

         A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over other Holders.

SECTION  6.7.    RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and premium, if any, interest and
Liquidated Damages, if any, on, such Securities on the Stated Maturity therefor
and to institute suit for the enforcement of any such overdue payment, and such
right may not be impaired without the consent of such Holder.

Section  6.8.    COLLECTION SUIT BY TRUSTEE.

         If an Event of Default in payment of principal, premium, if any,
interest or Liquidated Damages, if any, specified in Section 6.1(1), (2) or (3)
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company or any Guarantor for the
whole amount of principal, premium, if any, interest and Liquidated Damages, if
any, remaining unpaid with respect to the Securities, and interest on overdue
principal and premium, if any, and, to the extent lawful, interest on overdue
interest and Liquidated Damages, if any, and such further amounts as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation and expenses of the Trustee, its agents and counsel.

SECTION  6.9.    TRUSTEE MAY FILE PROOFS OF CLAIM.

         (a)     The Trustee is authorized to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expense, disbursements and advances of the Trustee, its agent and counsel) and
the Holders allowed in any judicial proceedings relative to the Company, the
Guarantors, their creditors or their property and may, and shall be entitled
and empowered to, collect, receive and distribute any money, securities or
other property payable or deliverable on any such claims and to distribute the
same, and any custodian in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.7.  To the extent that
the payment of any such compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any other amounts due the Trustee
under Section 7.7 hereof out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties that the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

         (b)     Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof, or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding.

SECTION  6.10.   PRIORITIES.

         If the Trustee collects any money pursuant to this Article VI, it
shall pay out the money in the following order:

                          First:  to the Trustee, its agents and attorneys, for
                 amounts due under Section 7.7, including payment of all
                 compensation, expense and liabilities incurred, and all
                 advances made, by the Trustee and the Trustee's costs and
                 expenses of collection;

                          Second:  to Holders for amounts due and unpaid on the
                 Securities for principal, premium, if any, interest and
                 Liquidated Damages, if any, ratably, without preference or
                 priority of any kind, according to the amounts due and payable
                 on the Securities for principal, premium, if any, interest and
                 Liquidated Damages, if any, respectively; and

                          Third:    to the Company or to such Person as a court
                 of competent jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10.

SECTION  6.11.   UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in




                                     56

<PAGE>   63
the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and
good faith of the claims or defenses made by the party litigant.  This Section
6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.7, or a suit by Holders of more than 10% in principal amount of the
then outstanding Securities.

                                  ARTICLE VII

                                    TRUSTEE

SECTION  7.1.    DUTIES OF TRUSTEE.

         (a)     If an Event of Default of which the Trustee has notice (to the
extent the Trustee is deemed to have notice as expressly provided in Section
7.1(g)) has occurred and is continuing, the Trustee shall exercise such rights
and powers vested in it by this Indenture and use the same degree of care and
skill in such exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

         (b)     Except during the continuance of an Event of Default of which
the Trustee has notice (to the extent the Trustee is deemed to have notice as
expressly provided in Section 7.1(g)):

                 (1)      The duties of the Trustee shall be determined solely
         by the express provisions of this Indenture, and the Trustee need
         perform only those duties that are specifically set forth (or
         incorporated by reference) in this Indenture and no others, and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee.

                 (2)      In the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture.  However, the Trustee shall examine such
         certificates and opinions to determine whether or not they conform to
         the requirements of this Indenture.

         (c)     The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                 (1)      This paragraph (c) does not limit the effect of the
                          preceding Section 7.1(b).

                 (2)      The Trustee shall not be liable for any error of
         judgment made in good faith by an officer of the Trustee, unless it is
         proved that the Trustee was negligent in ascertaining the pertinent
         facts.

                 (3)      The Trustee shall not be liable with respect to
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.5, and the Trustee
         shall be entitled from time to time to request such a direction.

         (d)     Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.1.




                                     57

<PAGE>   64
         (e)     The Trustee shall be under no obligation and may refuse to
perform any duty or exercise any right or power unless it receives indemnity
satisfactory to it against any loss, liability or expense.  No provision of
this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers, if it shall have
reasonable grounds to believe that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

         (f)     The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

         (g)     Subject to Sections 7.1 and 7.2, the Trustee shall not be
required to inquire as to, to take notice of, and shall not be deemed to have
notice of, any Default or Event of Default hereunder, except Events of Default
described in paragraphs (1), (2) and (3) of Section 6.1, unless the Trustee
shall be notified specifically of the Default or Event of Default in a written
instrument or document delivered to it by the Company or any Guarantor, or by
the Holders of at least ten percent (10%) of the aggregate principal amount of
the Securities then outstanding or it shall have obtained actual knowledge
thereof.  In the absence of delivery of a notice satisfying those requirements
or such actual knowledge, the Trustee may assume that there is no Default or
Event of Default, except as noted above.

SECTION  7.2.    RIGHTS OF TRUSTEE.

         Subject to Section 7.1:

         (a)     The Trustee may conclusive rely on, and shall be protected in
acting or refraining from acting upon, any document believed by it to be
genuine and to have been signed or presented by the proper person.  The Trustee
shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee
shall determine to make such further inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Company and the
Guarantors, personally or by agent or attorney, to the extent reasonably
required by such inquiry or investigation.

         (b)     Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel, or both.  The
Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on such certificate or opinion.  The Trustee may consult with
counsel, and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

         (c)     The Trustee may act through its agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

         (d)     The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within the
rights or powers conferred upon it by this Indenture.




                                     58
<PAGE>   65
SECTION  7.3.    INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or its
Subsidiaries or Affiliates with the same rights it would have if it were not
Trustee.  However, in the event that the Trustee acquires any conflicting
interest, it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee and not be denied such permission, or resign.
Any Agent may do the same with like rights.  However, the Trustee must comply
with Sections 7.10 and 7.11.

SECTION  7.4.    TRUSTEE'S DISCLAIMER.

         The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall
not be accountable for the Company's use of the proceeds from the Securities or
any money paid to the Company or upon the Company's direction under any
provision of this Indenture, it shall not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee,
and it shall not be responsible for any statement or recital herein or any
statement in the Securities or any other document in connection with the sale
of the Securities or pursuant to this Indenture other than its certificate of
authentication.

SECTION  7.5.    NOTICE OF DEFAULTS.

         If a Default or an Event of Default occurs and is continuing, and if
it is known to the Trustee pursuant to Section 7.1(g), the Trustee shall mail
to each Holder pursuant to Section 11.2 a notice of the Default or Event of
Default within 90 days after it occurs.  Except in the case of a Default or an
Event of Default in any payment on any Security, the Trustee may withhold the
notice if and so long as its Board of Directors, executive committee or a trust
committee of officers in good faith determines that withholding the notice is
in the interests of Holders.

SECTION  7.6.    REPORTS BY TRUSTEE TO HOLDERS.

         Within 60 days after each May 15, beginning with the May 15 following
the date of this Indenture, the Trustee shall mail to each Holder a brief
report dated as of such May 15, that complies with TIA Section  313(a), but
only if such report is required in any year under TIA Section  313(a).  The
Trustee also shall comply with TIA Sections  313(b) and 313(c).

         A copy of each report at the time of its mailing to Holders shall be
(i) mailed to the Company and (ii) filed with the SEC and each stock exchange
on which the Securities are listed in accordance with TIA Section  313(d).  The
Company shall promptly notify the Trustee in writing when the Securities become
listed on any national securities exchange or of any delisting thereof.

SECTION  7.7.    COMPENSATION AND INDEMNITY.

         The Company and the Guarantors jointly and severally agree to pay the
Trustee from time to time reasonable compensation for its services under this
Indenture (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust).  The Company and
the Guarantors jointly and severally agree to reimburse the Trustee promptly
upon request for all reasonable out-of-pocket expenses, disbursements and
advances incurred by it.  Such expenses shall include when applicable the
reasonable compensation and expenses of the Trustee's agents and counsel.




                                     59

<PAGE>   66
         The Company and the Guarantors jointly and severally agree to
indemnify the Trustee against any loss, liability or expenses incurred by it
arising out of or in connection with the acceptance and administration of the
trust and its duties hereunder as Trustee, Registrar and/or Paying Agent,
including the costs and expenses of enforcing this Indenture against the
Company (including with respect to this Section 7.7) and of defending itself
against any claim or liability in connection with the exercise or performance
of any of its powers or duties hereunder.  The Trustee shall notify the Company
and the Guarantors of any claim for which it may seek indemnity; however,
unless the position of the Company is prejudiced by such failure, the failure
of the Trustee to promptly notify the Company shall not limit its right to
indemnification.  The Company shall defend each such claim and the Trustee
shall cooperate in the defense.  The Trustee may retain separate counsel and
the Company shall reimburse the Trustee for the reasonable fees and expenses of
such counsel if the Company is advised by an Opinion of Counsel that the
Trustee has separate defenses and that separate representation is appropriate.
The Company need not pay for any settlement made without its consent, which
consent shall not be unreasonably withheld.

         Neither the Company nor the Guarantors shall be obligated to reimburse
any expense or indemnify against any loss or liability incurred by the Trustee
through the Trustee's breach of the applicable standard of care for its conduct
under Section 7.1.

         The obligations of the Company and the Guarantors under this Section
7.7 shall survive the satisfaction and discharge of this Indenture.

         To secure the payment obligations of the Company and the Guarantors in
this Section 7.7, the Trustee shall have a Lien prior to the Securities on all
money or property held or collected by the Trustee, except that held in trust
to pay principal of and interest on particular Securities.  Such Lien shall
survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after the
occurrence of an Event of Default specified in Section 6.1(11) or (12), the
expenses and the compensation for the services (including the fees and expenses
of its agent and counsel) are intended to constitute expenses of administration
under any Bankruptcy Law.

         The Trustee shall comply with the provisions of TIA Section  313(b)(2)
to the extent applicable.

SECTION  7.8.    REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.8.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company.  The Holders of a
majority in principal amount of the then outstanding Securities may remove the
Trustee by so notifying the Trustee and the Company, in writing.  The Company
may remove the Trustee if:

                 (1)      the Trustee fails to comply with Section 7.10;

                 (2)      the Trustee is adjudged a bankrupt or an insolvent or
         an order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

                 (3)      a Custodian or other public officer takes charge of
         the Trustee or its property; or




                                     60

<PAGE>   67
                 (4)      the Trustee becomes incapable of acting as Trustee 
         hereunder.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee.  Within one year after the successor Trustee takes office,
the Holders of a majority in principal amount of the then outstanding
Securities may appoint a successor Trustee to replace the successor Trustee
appointed by the Company.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after
that, the retiring Trustee shall transfer all property held by it as Trustee to
the successor Trustee, subject to the Lien provided for in Section 7.7, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture.  A successor Trustee shall mail notice of its succession
to each Holder.

         If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or
the Holders of a majority in principal amount of the then outstanding
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

         If the Trustee fails to comply with Section 7.10, any such Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.  Any successor Trustee shall comply
with TIA Section  310(a)(5).

SECTION  7.9.    SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust assets to, another corporation, the
successor corporation without any further act shall be the successor Trustee;
provided such corporation or association shall be otherwise eligible and
qualified under this Article.  As soon as practicable, the successor Trustee
shall mail a notice of its succession to the Company and the Holders.

SECTION  7.10.   ELIGIBILITY; DISQUALIFICATION.

         This Indenture shall always have a Trustee which satisfies the
requirements of TIA Section  310(a)(1) and (5).  The Trustee shall always have
a combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition.  The Trustee shall also comply
with TIA Section  310(b).

SECTION  7.11.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee shall comply with TIA Section  311(a), excluding any
creditor relationship listed in TIA Section 311(b).  A Trustee who has resigned
or been removed shall be subject to TIA Section  311(a) to the extent indicated
therein.

obligations with respect to all outstanding Securities, and each Guarantor
shall be deemed to have discharged its obligation with respect to its
Guarantee, on the date all conditions set forth below are satisfied
(hereinafter, "LEGAL DEFEASANCE").  For this purpose, Legal Defeasance means
that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Securities, and each Guarantor
shall be deemed to have paid and discharged its Guarantee (which in each case
shall thereafter be deemed to be "outstanding" only for the purposes of Section
8.5 and the other Sections of this Indenture referred to in clauses (a) and (b)
of this Section 8.2) and to have satisfied all its other obligations under such
Securities or Guarantee and this Indenture (and the Trustee, on demand of and
at the expense of the Company, shall execute proper instruments acknowledging
the same), except for the following which shall survive until otherwise
terminated or discharged hereunder: (a) the rights of Holders of outstanding
Securities to receive solely from the trust fund described in Section 8.4, and
as more fully set forth in such Section, payments in respect of the principal
of, and premium, if any, interest and Liquidated Damages, if any, on, such
Securities when such payments are due, (b) the Company's obligations with
respect to such Securities under Sections 2.3, 2.4, 2.6, 2.7, 2.10 and 4.4, (c)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company's obligations in connection therewith (including Section 7.7) and
(d) this Article VIII.  Subject to compliance with this Article VIII, the
Company may exercise its option under this Section 8.2 notwithstanding the
prior exercise of its option under Section 8.3 with respect to the Securities.

SECTION  8.3.    COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 8.1 of the option applicable
to this Section 8.3, the Company shall be released from its obligations under
the covenants contained in Sections 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13,
4.14, 4.15, 4.16, 4.17 and 4.18 and paragraph (2) of Section 5.1 on and after
the date the conditions set forth below are satisfied (hereinafter, "COVENANT
DEFEASANCE"), and the Securities shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Securities shall not be deemed
outstanding for accounting purposes).  For this purpose, such Covenant
Defeasance means that, with respect to the outstanding Securities, the Company
and any Guarantor may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.1(4) (as
applicable) or Section 6.1(5), but, except as specified above,




                                     62

<PAGE>   69
the remainder of this Indenture and such Securities shall be unaffected
thereby.  In addition, upon the Company's exercise under Section 8.1 of the
option applicable to this Section 8.3, Sections 6.1(6) through 6.1(10) shall
not constitute Events of Default.

SECTION  8.4.    CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of Section 8.2 or
Section 8.3, as the case may be, to the outstanding Securities:

         (a)     The Company shall irrevocably have deposited or cause to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 7.10 who shall agree to comply with the provisions of this Article VIII
applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities, (a) cash in U.S. Legal
Tender in an amount, or (b) U.S. Government Securities which through the
scheduled payment of principal and interest in respect thereof in accordance
with their terms will provide, not later than one day before the due date of
any payment, cash in U.S. Legal Tender in an amount, or (c) a combination
thereof, in such amounts, as will be sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge and which
shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge the principal of, and premium, if any, interest and Liquidated
Damages, if any, on, the outstanding Securities on the Stated Maturity or on
the applicable redemption date, as the case may be, in accordance with the
terms of this Indenture and of such Securities; provided that the Trustee shall
have been irrevocably instructed to apply such money or the proceeds of such
U.S. Government Securities to said payments with respect to the Securities;

         (b)     In the case of an election under Section 8.2, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (ii) since the date hereof, 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
Securities 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;

         (c)     In the case of an election under Section 8.3, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Securities 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;

         (d)     No Default or Event of Default with respect to the Securities
shall have occurred and be continuing on the date of such deposit or, insofar
as Subsection 6.1(11) or 6.1(12) is concerned, at any time in the period ending
on the 91st (or, if such deposit may be subject to set aside or avoidance under
any then applicable Bankruptcy Law for a period of time longer than 90 days,
the one day after the




                                     63
<PAGE>   70
conclusion of such longer period) day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period);

         (e)     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;

         (f)     In the case of any election under Section 8.2 or 8.3, the
Company shall have delivered to the Trustee an Officers' Certificate stating
that the deposit made by the Company pursuant to its election under Section 8.2
or 8.3 was not made by the Company with the intent of preferring the Holders
over other creditors of the Company or with the intent of defeating, hindering,
delaying or defrauding creditors of the Company or others; and

         (g)     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 either the Legal Defeasance under Section
8.2 or the Covenant Defeasance under Section 8.3 (as the case may be) have been
complied with as contemplated by this Section 8.4.

SECTION  8.5.    DEPOSITED MONEY AND U.S. GOVERNMENT SECURITIES TO BE HELD IN
                 TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to Section 8.6, all money and U.S. Government Securities
(including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.5, the
"Trustee") pursuant to Section 8.4 in respect of the outstanding Securities
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as Paying
Agent) as the Trustee may determine, to the Holders of such Securities of all
sums due and to become due thereon in respect of principal, premium, if any,
interest and Liquidated Damages, if any, but such money need not be segregated
from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or U.S. Government
Securities deposited pursuant to Section 8.4 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the outstanding Securities.

         Anything in this Article VIII to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the
Company's request any money or U.S. Government Securities held by it as
provided in Section 8.4 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.4(a)), are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION  8.6.    REPAYMENT TO COMPANY.

         Subject to applicable escheat and abandoned property laws, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, or premium, if any, interest or
Liquidated Damages, if any, on, any Security and remaining unclaimed for two
years after such principal, and premium, if any, interest or Liquidated
Damages, if any, has become due and payable shall be paid to the Company on its
request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general




                                     64


<PAGE>   71
creditor, look only to the Company for payment thereof, and all liability of
the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Company cause to be published
once, in The New York Times and The Wall Street Journal (national edition),
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

SECTION  8.7.    REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or  U.S. Government Securities in accordance with Section 8.5 by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the Company's
obligations under this Indenture and the Securities, and each Guarantor's
obligations under its Guarantor, shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.2 or 8.3 until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 8.5; provided, however, that, if the Company makes any payment of
principal of, or premium, if any, interest or Liquidated Damages, if any, on,
any Security following the reinstatement of its obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money held by the Trustee or Paying Agent.

                                   ARTICLE IX

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION  9.1.    WITHOUT CONSENT OF HOLDERS.

         Notwithstanding Section 9.2, the Company, the Guarantors and the
Trustee may amend or supplement this Indenture or the Securities without notice
to or consent of any Holder:

                 (1)      to cure any ambiguity, omission, defect or
         inconsistency;

                 (2)      to comply with Section 5.1;

                 (3)      to reflect the addition or release of any Guarantor,
         as provided for by this Indenture;

                 (4)      to comply with any requirements of the SEC in order
         to effect or maintain the qualification of this Indenture under the
         TIA; or

                 (5)      to make any change that would provide any additional
         benefit or rights to the Holders or that does not adversely affect the
         rights of any Holder in any material respect.

         Upon the request of the Company, accompanied by a Board Resolution of
the Company and of each Guarantor authorizing the execution of any such
supplemental indenture, and upon receipt by the Trustee of the documents
described in Section 9.6, the Trustee shall join with the Company and the
Guarantors in the execution of any amended or supplemental indenture authorized
or permitted by the terms of this Indenture and make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee
shall not be obligated to enter into such amended or supplemental Indenture
that affects its own rights, duties or immunities under this Indenture or
otherwise.  After an amendment




                                     65

<PAGE>   72
or waiver under this Section becomes effective, the Company shall mail to the
Holders of each Security affected thereby a notice briefly describing the
amendment or waiver.  Any failure of the Company to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

SECTION  9.2.    WITH CONSENT OF HOLDERS.

         Except as provided below in this Section 9.2, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the
Securities with the written consent (including consents obtained in connection
with a tender offer or exchange offer for Securities or a solicitation of
consents in respect of Securities, provided that in each case such offer or
solicitation is made to all Holders of then outstanding Securities on equal
terms) of the Holders of at least a majority in principal amount of the then
outstanding Securities, and subject to Sections 6.4 and 6.7, any existing
Default or Event of Default or compliance with any provision of this Indenture
or the Securities may be waived with the consent of the Holders of a majority
in principal amount of the then outstanding Securities (including consents
obtained in connection with a tender offer or exchange offer for the
Securities).

         Upon the request of the Company accompanied by a Board Resolution of
the Company and each Guarantor authorizing the execution of any such amended or
supplemental indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders as aforesaid, and
upon receipt by the Trustee of the documents described in Section 9.6, the
Trustee shall join with the Company and the Guarantors in the execution of such
supplemental indenture unless such amended or supplemental indenture affects
the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such amended or supplemental indenture.

         It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

         After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver.  Any failure of the
Company to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such amended or supplemental Indenture
or waiver.  Subject to Sections 6.4 and 6.7, the Holders of a majority in
principal amount of the Securities then outstanding may waive compliance in a
particular instance by the Company with any provision of this Indenture or the
Securities.  However, without the consent of each Holder affected, an
amendment, supplement or waiver may not (with respect to any Securities held by
a non-consenting Holder):

                 (1)      reduce the percentage of principal amount of
         Securities whose Holders must consent to an amendment, supplement or
         waiver of any provision of this Indenture or the Securities;

                 (2)      reduce the rate or change the time for payment of
         interest, including defaulted interest, or Liquidated Damages, if any,
         on the Securities;

                 (3)      reduce the principal amount of any Security or change
         the Maturity Date of the Securities;



                                     66


<PAGE>   73
                 (4)      reduce the redemption price, including premium, if
         any, payable upon the redemption of any Security or change the time at
         which any Security may or shall be redeemed;

                 (5)      reduce the repurchase price, including premium, if
         any, payable upon the repurchase of any Security pursuant to Section
         4.11 or 4.17, or change the time at which any Security may or shall be
         repurchased thereunder;

                 (6)      waive a continuing Default or Event of Default in the
         payment of the principal of, or premium, if any, interest or
         Liquidated Damages, if any, on, the Securities;

                 (7)      make any Security payable in money other than that
         stated in the Security;

                 (8)      impair the right to institute suit for the
         enforcement of any payment of principal of, or premium, if any,
         interest or Liquidated Damages, if any, on, any Security pursuant to
         Section 6.7 or 6.8, except as limited by Section 6.6; or

                 (9)      make any change in Section 6.4 or Section 6.7 or in
         this sentence of this Section 9.2.

         The right of any Holder to participate in any consent required or
sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of
record of any Securities with respect to which such consent is required or
sought as of a date identified by the Trustee in a notice furnished to Holders
in accordance with the terms of this Indenture.

SECTION  9.3.    COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment to or supplement of this Indenture or the Securities
shall comply with the TIA as then in effect.

SECTION  9.4.    REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Security shall bind the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made
on any Security.  However, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security if the Trustee receives
written notice of revocation before the date the amendment, supplement or
waiver becomes effective.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver.  If the Company elects to fix a record date for such
purpose, the record date shall be fixed at (i) the later of 30 days prior to
the first solicitation of such consent or the date of the most recent list of
Holders furnished to the Trustee prior to such solicitation pursuant to Section
2.5, or (ii) such other date as the Company shall designate.  If a record date
is fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to consent to
such amendment or waiver or to revoke any consent previously given, whether or
not such Persons continue to be Holders after such record date.  No consent
shall be valid or effective for more than 90 days after such record date unless
consent from the Holders of the principal




                                     67
<PAGE>   74
amount of Securities required hereunder for such amendment or waiver to be
effective also shall have been given and not revoked within such 90-day period.

         An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter, it shall bind every Holder unless it makes a
subsequent change described in any of clauses (1) through (9) of Section 9.2.
In that case the amendment, supplement or waiver shall bind each Holder of a
Security who has consented to it and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security.

SECTION  9.5.    NOTATION ON OR EXCHANGE OF SECURITIES.

         If an amendment, supplement or waiver changes the terms of a Security,
the Company or the Trustee may require the Holder of the Security to deliver it
to the Trustee.  The Trustee may place an appropriate notation on the
re-delivered Security about the changed terms and return it to the Holder and
on any Security thereafter authenticated.  If the Company or the Trustee so
determines, the Company in exchange for all Securities may issue and the
Trustee shall authenticate new Securities that reflects the changed terms.
Failure to make the appropriate notation or issue a new Security shall not
affect the validity and effect of such amendment, supplement or waiver.

SECTION  9.6.    TRUSTEE PROTECTED.

         The Trustee shall sign any amended or supplemental Indenture or waiver
authorized pursuant to this Article IX if the amendment or supplement or waiver
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee.  Neither the Company nor any of its Subsidiaries may sign an amended
or supplemental indenture until its respective Board of Directors approves it.
In signing such amendment or supplement or waiver the Trustee shall be entitled
to receive, and (subject to Article VII) shall be fully protected in relying
upon, an Opinion of Counsel stating that such amendment or supplement or waiver
is authorized or permitted by and complies with this Indenture.  The Company
may not sign an amendment or supplement until the Boards of Directors of the
Company and the Guarantors approve it.

SECTION  9.7.    RESTRICTIONS ON PAYMENTS FOR AMENDMENTS, WAIVERS AND 
                 MODIFICATIONS.

         Notwithstanding any provision to the contrary contained or referred to
in this Indenture, the Company shall not, and shall not permit any of its
Subsidiaries directly or indirectly, to pay or cause to be paid any
consideration, whether by way of interest, premium, fee or otherwise, to any
Holder for or as an inducement to any consent, waiver, amendment or supplement
of any terms or provisions of the Security or this Indenture, unless such
consideration is offered to be paid or agreed to be paid to all Holders which
so consent, waive or agree to amend or supplement in the time frame set forth
in any solicitation documents relating to such consent, waiver or agreement.

                                   ARTICLE X

                                   GUARANTEES

SECTION  10.1.   UNCONDITIONAL GUARANTEE.

         Each Guarantor hereby, jointly and severally, fully, absolutely,
unconditionally and irrevocably guarantees (such guarantee to be referred to
herein as the "GUARANTEE") to each Holder and to the Trustee the due and
punctual payment of the principal of, and premium, if any, interest and
Liquidated Damages, if any, on, on the Securities and all other amounts due and
payable under this Indenture and the Securities by the Company whether at
maturity, by acceleration, redemption, repurchase or otherwise, including
interest on the overdue principal of, and premium, if any, interest and
Liquidated Damages,




                                     68

<PAGE>   75
if any, on, the Securities, to the extent lawful, all in accordance with the
terms hereof and thereof; subject, however, to the limitations set forth in
Section 10.5; and in case of any extension of time of payment or renewal of any
Securities or any of such other Obligations, the same will be promptly paid in
full when due or performed in accordance with the terms of the extension or
renewal, subject to any applicable grace period, whether at stated maturity, by
acceleration, redemption, repurchase or otherwise.

         Failing payment when due of any amount so guaranteed for whatever
reason, the Guarantors will be jointly and severally obligated to pay the same
immediately.  An Event of Default under this Indenture or the Securities shall
constitute an event of default under this Guarantee, and shall entitle the
Holders to accelerate the obligations of the guarantors hereunder in the same
manner and to the same extent as the Obligations of the Company.  Each
Guarantor hereby agrees that its obligations hereunder shall be absolute and
unconditional, irrespective of the validity, regularity or enforceability of
the Securities or this Indenture, the absence of any action to enforce the
same, any waiver or consent by any Holder with respect to any provisions hereof
or thereof, the recovery of any judgment against the Company, any action to
enforce the same or any other event or circumstance (including any statute of
limitations), whether foreseen or unforeseen or whether similar or dissimilar
to the foregoing, which might otherwise constitute a legal or equitable
discharge or defense of a guarantor, and in no event or circumstance, shall its
obligations hereunder be released, discharged, mitigated, waived, impaired or
affected in whole or in part except for its final and complete payment and
performance hereof or pursuant to the express provisions of Section 10.4.  To
the fullest extent permitted by law, each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest, notice (including notice of intent to
accelerate or notice of acceleration) and all demands whatsoever and covenants
that this Guarantee will not be discharged except by complete performance of
the obligations contained in the Securities, this Indenture and in this
Guarantee.  If any Holder or the Trustee is required by any court or otherwise
to return to the Company, any Guarantor, any Securities Custodian, any
Custodian or trustee, liquidator or other similar official acting in relation
to either the Company or any Guarantor, any amount paid by the Company or any
Guarantor to the Trustee or such Holder with respect to the Securities, this
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.  Each Guarantor agrees it shall not be entitled to, and
hereby waives, any right of subrogation in relation to the Holders in respect
of any obligations guaranteed hereby until final payment in full of all
obligations guaranteed hereby.  Each Guarantor further agrees that, as between
each Guarantor, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the obligations guaranteed hereby may be accelerated
as provided in Article VI for the purposes of this Guarantee, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in
respect of the obligations guaranteed hereby, and (y) in the event of any
declaration of acceleration of such obligations as provided in Article VI, such
obligations (whether or not due and payable) shall forthwith become due and
payable by each Guarantor for the purpose of this Guarantee.

         The obligations of each Guarantor under its Guarantee are independent
of the obligations of the Company under the Securities and this Indenture, and
a separate action or actions may be brought  and prosecuted against such
Guarantor to enforce its Guarantee, irrespective of whether any action is
brought against the Company or any other Guarantor or  whether the Company or
any other Guarantor is joined in any such action or actions.

SECTION  10.2.   GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

         (a)     Subject to paragraph (b) of this Section 10.2, no Guarantor
may consolidate with or merge with or into (whether or not such Guarantor is
the surviving Person) another corporation or 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 Securities, the Indenture
and, if applicable, the Registration Rights Agreement, (ii) immediately before
and after giving effect to such transaction, no Default or Event of Default
exists, (iii) such Guarantor or the entity or 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 pursuant to Section 4.9(a).  In connection with any
consolidation or merger contemplated by this Section 10.2, the Company shall
deliver to the Trustee prior to the consummation of the proposed transaction an
Officers' Certificate to the foregoing effect and an Opinion of Counsel stating
that all conditions precedent to the proposed transaction and to execution and
delivery of such supplemental indenture have been complied with.  This Section
10.2(a) will not prohibit a merger between Guarantors or a merger between the
Company and a Guarantor.

         (b)     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 such Guarantor, then such 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 Guarantees; provided that the Net Cash Proceeds of such
sale or other disposition are applied in accordance with the provisions of the
Indenture described under Section 4.11.

SECTION  10.3.   ADDITION OF GUARANTORS.

         (a)     The Company agrees to cause each Person that is or becomes a
Restricted Subsidiary on or after the Issue Date to become a Guarantor to the
full extent as provided by this Article X by executing and delivering to the
Trustee a supplemental indenture pursuant to which such Restricted Subsidiary
shall guarantee the payment of the Securities pursuant to the terms hereof, and
any Person that was not a Guarantor on the Issue Date may so become a Guarantor
by executing and delivering to the Trustee, in each case as to such Restricted
Subsidiary or Person (as applicable), (i) a supplemental indenture in form and
substance satisfactory to the Trustee, which subjects such Restricted
Subsidiary or Person to the provisions (including the representations and
warranties) of this Indenture as a Guarantor and (ii) an Opinion of Counsel and
Officers' Certificate to the effect that such supplemental indenture has been
duly authorized and executed by such Restricted Subsidiary or Person and
constitutes the legal, valid, binding and enforceable obligation of such
Restricted Subsidiary or Person (subject to such customary exceptions
concerning creditors' rights and equitable principles as may be acceptable to
the Trustee in its discretion).

         (b)     The Company hereby represents and warrants that no Restricted
Subsidiaries and Guarantors are in existence on the Issue Date.

SECTION  10.4.   RELEASE OF A GUARANTOR.

         Upon the sale or disposition of, or with respect to, a Guarantor (or
substantially all of its assets) as expressly provided in Section 10.2(b) or
the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary, which
in each case otherwise is effected in compliance with the terms of this
Indenture, such Guarantor shall be deemed released from all of its Guarantee
and related obligations in this Indenture.  The Trustee shall deliver an
appropriate instrument evidencing such release upon receipt of a request by the
Company accompanied by an Officers' Certificate and an Opinion of Counsel
certifying that such sale or other disposition or designation (as applicable)
was made by the Company in accordance with the provisions of this Indenture.
Any Guarantor not so released remains liable for the full amount of the
Securities or other amounts as provided in this Article X.

SECTION  10.5.   LIMITATION OF GUARANTOR'S LIABILITY.

         Each Guarantor and by its acceptance of Securities under this
Indenture each Holder hereby confirms that it is the intention of all such
parties that the guarantee by such Guarantor pursuant to its Guarantee not
constitute a fraudulent transfer or conveyance for purposes of any federal,
state or foreign law.  To effectuate the foregoing intention, the Holders and
each Guarantor hereby irrevocably agree that the obligations of each Guarantor
under the Guarantee shall be limited to the maximum 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 Guarantor in respect of the obligations of such other
Guarantor under its Guarantee or pursuant to Section 10.6, result in the
obligations of such Guarantor under the Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under federal, state or foreign law.  This
Section 10.5 is for the benefit of the creditors of each Guarantor, and, for
purposes of applicable fraudulent transfer and fraudulent conveyance law, any
Indebtedness of a Guarantor pursuant to a Bank Credit Facility shall be deemed
to have been incurred prior to the incurrence by such Guarantor of its
liability under the Guarantee.

SECTION  10.6.   CONTRIBUTION.

         In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a "FUNDING GUARANTOR") under the
Guarantee, such Funding Guarantor shall be entitled to a contribution from each
other Guarantor in a pro rata amount based on the Adjusted Net Assets of each
Guarantor (including the Funding Guarantor) for all payments, damages and
expenses incurred by the Funding Guarantor in discharging the Company's
obligations with respect to the Securities or any other Guarantor's obligations
with respect to the Guarantee.

SECTION  10.7.   EXECUTION AND DELIVERY OF GUARANTEE.

         To further evidence its Guarantee set forth in Section 10.1, each
Guarantor hereby agrees that a notation relating to such Guarantee, in
substantially the form of Exhibit D, shall be endorsed on each Security
authenticated and delivered by the Trustee and executed by either manual or
facsimile signature of one Officer of each Guarantor.

         Each of the Guarantors hereby agrees that its Guarantee shall remain
in full force and effect notwithstanding any failure to endorse on each
Security a notation of such Guarantee.

         If an Officer of a Guarantor whose signature is on this Indenture, a
Guarantee or a Security, or a supplemental indenture or notation with respect
to any of them, no longer holds that office at the time




                                     71
<PAGE>   78
the Trustee authenticates such Security or at any time thereafter, such
Guarantor's Guarantee of such Security shall be valid nevertheless.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee on behalf of
the Guarantor.

SECTION  10.8.   "TRUSTEE" TO INCLUDE PAYING AGENT.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article 10 shall in each case (unless the context shall
otherwise require) be construed as extending to and including such Paying Agent
within its meaning as fully and for all intents and purposes as if such Paying
Agent were named in this Article X in place of the Trustee.

SECTION  10.9.   SEVERABILITY.

         In case any provision of this Guarantee shall be invalid, illegal or
unenforceable, that portion of such provision that is not invalid, illegal or
unenforceable shall remain in effect, and the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

Ladies and Gentlemen:

                  Michael Petroleum Corporation, a Texas corporation (the
"Company"), proposes to issue and sell to you (the "Initial Purchasers"), upon
the terms set forth in a purchase agreement of even date herewith (the "Purchase
Agreement"), $135,000,000 principal amount of the Company's 11 1/2% Senior Notes
due 2005 (the "Notes"). The Notes will be issued pursuant to an indenture, to be
dated as of April 2, 1998 (the "Indenture") by and between the Company and State
Street Bank and Trust Company, as trustee (the "Trustee"), substantially in the
form previously furnished to you.

                  Capitalized terms used but not specifically defined herein are
defined in the Purchase Agreement and used herein as so defined. As used herein,
"Registrable Notes" shall mean each Note, until the earliest to occur of (a) the
date on which an Exchange Offer is completed for the Notes pursuant to which
such Note may be exchanged in the Exchange Offer for an Exchange Note (each as
defined below) and entitled to be resold to the public by the holder thereof
without complying with the prospectus delivery requirements of the Securities
Act of 1933, as amended (the "Securities Act"), (b) the date on which such Note
has been effectively registered under the Securities Act and disposed of
pursuant to a Notes Shelf Registration (as defined below), (c) the date on which
such Note is distributed to the public pursuant to Rule 144 under the Securities
Act or by a Broker-Dealer (as defined below) pursuant to the "Plan of
Distribution" contemplated by the registration statement relating to the
Exchange Offer (including delivery of the prospectus contained therein) or (d)
the date such Note ceases to be outstanding.

                  In consideration of the premises, and the mutual covenants,
representations, warranties and agreements herein contained, the parties hereby
agree as follows:

                  1.       Exchange Offer.

                  (a)      Promptly (and in any event not more than 45 days)
following the Closing Date, the Company shall file with the Commission a
registration statement on an appropriate form under the Securities Act with
respect to a proposed offer (the "Exchange Offer") to the holders of the
Registrable Notes to issue and deliver to such holders, in exchange for the
Registrable Notes, a like principal amount of debt securities of the Company
identical in all material respects to the Registrable Notes (the "Exchange
Notes"), shall use its best efforts to cause such registration statement to
become effective under the Securities Act no later than 120 days after the
Closing Date and, upon the effectiveness of that registration statement, shall
commence



<PAGE>   2



the Exchange Offer and shall cause the same to remain open for such period of
time to be determined by the Company (but not less than 30 nor more than 60 days
after the commencement of the Exchange Offer), and to be conducted in accordance
with such procedures as may be required by the applicable provisions of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), it being the
objective of such Exchange Offer to enable each holder of Registrable Notes
electing to exchange Registrable Notes for Exchange Notes (assuming that such
holder is not an affiliate of the Company within the meaning of the Securities
Act, acquires the Exchange Notes in the ordinary course of such holder's
business and has no arrangements with any person to participate in the
distribution of the Exchange Notes) to trade such Registrable Notes for Exchange
Notes from and after their receipt without any limitations or restrictions under
the Securities Act, subject as to a Broker-Dealer to the provisions of Section
1(b) hereof, or the Exchange Act and without material restrictions under the
securities laws of a substantial proportion of the several states of the United
States. Each holder of Registrable Notes who participates in the Exchange Offer
and who desires to receive Exchange Notes that will not be subject to any
limitations or restrictions on resale under the Securities Act will be required
to represent in writing to the Company that any Exchange Notes received by it
will be acquired in the ordinary course of its business, that at the time of
consummation of the Exchange Offer such holder of Registrable Notes will have no
arrangement or understanding with any person to participate in the distribution
of the Exchange Notes and that such holder of the Registrable Notes is not an
affiliate of the Company within the meaning of the Securities Act. Upon
consummation of the Exchange Offer in accordance with this Section 1, the
Company shall have no further obligation to register Registrable Notes pursuant
to Section 2 of this Agreement.

                  (b)      The Company shall indicate in a "Plan of 
Distribution" section contained in the final prospectus constituting a part of
the registration statement relating to the Exchange Offer that any broker or
dealer registered under the Exchange Act (each a "Broker-Dealer") who holds
Registrable Notes that were acquired for its own account as a result of
market-making activities or other trading activities (other than Registrable
Notes acquired directly from the Company), may exchange such Registrable Notes
for Exchange Notes pursuant to the Exchange Offer; however, such Broker-Dealer
may be deemed an "underwriter" within the meaning of the Securities Act and,
therefore, must deliver a prospectus meeting the requirements of the Securities
Act in connection with any resales of the Exchange Notes received by it in the
Exchange Offer, which prospectus delivery requirement may be satisfied by the
delivery by such Broker-Dealer of the final prospectus contained in the
registration statement relating to the Exchange Offer. Such "Plan of
Distribution" section also shall state that the delivery by a Broker-Dealer of
the final prospectus relating to the Exchange Offer in connection with resales
of Exchange Notes shall not be deemed to be an admission by such Broker- Dealer
that it is an "underwriter" within the meaning of the Securities Act, and shall
contain all other information with respect to resales of the Exchange Notes by
Broker-Dealers that the Commission may require in connection therewith, but such
"Plan of Distribution" shall not name any such Broker-Dealer or disclose the
amount of Exchange Notes held by any such Broker-Dealer except to the extent
required by the Commission as a result of a change in policy after the date of
this Agreement.

                  (c)      In connection with such Exchange Offer and the offer
and sale of Exchange Notes by Broker-Dealers as contemplated above, the Company
shall take such other and further action, including making appropriate filings
under state securities laws and delivering such number of final prospectuses
relating to the Exchange Offer as any Broker-Dealer proposing to deliver the
same in connection with its resales of Exchange Notes may reasonably request, as
may be necessary to realize the foregoing objectives. The Company shall cause
the registration statement relating to the Exchange Offer to remain continuously
effective for a period of one year from the date on which such registration
statement is first declared effective, and shall supplement or amend the
prospectus contained therein, in each case, to the extent necessary to


                                       -2-

<PAGE>   3



permit such prospectus (as supplemented or amended) to be delivered by
Broker-Dealers in connection with their resales of Exchange Notes as aforesaid.

                  2.       Notes Shelf Registration. The following provisions
shall apply, only if, because of any change in currently prevailing
interpretations of the Commission's staff, the Company is not permitted to
effect an Exchange Offer, as contemplated by Section 1 hereof:

                  (a)      Promptly (and in any event not more than 45 days)
following the Closing Date, the Company shall file with the Commission, and
thereafter use its best efforts to have declared effective not later than 120
days after the Closing Date, a registration statement on an appropriate form
under the Securities Act relating to the offer and sale of the Registrable Notes
by the holders thereof, from time to time in accordance with the methods of
distribution set forth in such registration statement and Rule 415 under the
Securities Act (the "Notes Shelf Registration").

                  (b)      The Company agrees to use its best efforts to keep
the registration statement relating to the Notes Shelf Registration continuously
effective in order to permit the prospectus included therein to be usable by the
holders of the Registrable Notes for a period of two years from the Closing Date
or such shorter period that will terminate when all the Registrable Notes
covered by the registration statement have been sold pursuant to such
registration statement; provided, that the Company shall be deemed not to have
used its best efforts to keep the registration statement effective during the
requisite period if it voluntarily takes any action that would result in holders
of the Registrable Notes covered thereby not being able to offer and sell such
Registrable Notes during that period, unless such action is required by
applicable law, and provided, further, that the foregoing shall not apply if the
Company determines, in its reasonable judgment, upon advice of counsel, as
authorized by a resolution of its Board of Directors, that the continued
effectiveness and usability of such registration statement would (i) require the
disclosure of material information, which the Company has a bona fide business
reason for preserving as confidential, or (ii) impede the consummation of any
financing, acquisition, corporate reorganization or other material transaction
involving the Company or any of its Affiliates (as defined in the rules and
regulations adopted under the Exchange Act); provided, however, that the failure
to keep the registration statement effective and usable for offers and sales of
Registrable Notes for such reasons shall last no longer than 30 days in any
12-month period, so long as the Company promptly thereafter complies with the
requirements of Section 3(h) hereof, if applicable. Any such period during which
the Company fails to keep the registration statement effective and usable for
offers and sales of Registrable Notes is referred to as a "Suspension Period." A
Suspension Period shall commence on and include the date that the Company gives
notice that the registration statement is no longer effective or the prospectus
included therein is no longer usable for offers and sales of Registrable Notes
and shall end on the date when each seller of Registrable Notes covered by such
registration statement either receives the copies of the supplemented or amended
prospectus contemplated by Section 3(h) hereof or is advised in writing by the
Company that use of the prospectus may be resumed.

                  (c)      Notwithstanding any other provisions of this
Agreement to the contrary, the Company will cause the Notes Shelf Registration
and the related prospectus and any amendment or supplement thereto, as of the
effective date of such registration statement, amendment or supplement, (i) to
comply in all material respects with the applicable requirements of the
Securities Act and the rules and regulations of the Commission and (ii) not to
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading.

                  3.       Registration Procedures. In connection with, to the
extent applicable, any Exchange Offer pursuant to Section 1 hereof, or any Notes
Shelf Registration pursuant to Section 2 hereof, the following provisions shall
apply:

                  (a)      If requested by any holder of Registrable Notes or
the managing underwriter, if any, with respect to the Notes Shelf Registration,
the Company shall furnish to each such holder of Registrable Notes or such
managing underwriter, prior to the filing thereof with the Commission, a copy of
the applicable registration statement and each amendment thereof and each
supplement, if any, to the prospectus included therein. The Company shall use
its best efforts to reflect in each such document, when so filed with the
Commission, such comments as such holder or managing underwriter reasonably may
propose.

                  (b)      The Company shall advise the holders of Registrable
Notes or the Exchange Notes, and the managing underwriter, if any, and, if
requested by any such person, confirm such advice in writing:

                  (i)      when the applicable registration statement and any
         amendment thereto has been filed with the Commission and when the
         registration statement or any post-effective amendment thereto has
         become effective;

                  (ii)     of the issuance by the Commission of any stop order
         suspending the effectiveness of the applicable registration statement
         or the initiation of any proceedings for that purpose;

                  (iii)    of the receipt by the Company of any notification
         with respect to the suspension of the qualification of the Registrable
         Notes or the Exchange Notes for sale in any jurisdiction or the
         initiation or threatening of any proceeding for such purpose; and

                  (iv)     of the happening of any event that requires the
         making of any changes in the registration statement or the prospectus
         in order to make the statements therein not misleading (which advice
         shall be accompanied by an instruction to suspend the use of the
         prospectus until the requisite changes have been made).

                  (c)      The Company will make every reasonable effort to 
obtain the withdrawal of any order suspending the effectiveness of the
registration statement at the earliest possible time.

                  (d)      The Company will furnish to each holder of the 
Registrable Notes or the Exchange Notes included within the coverage of the
Exchange Offer or the Notes Shelf Registration, as appropriate, without charge,
at least one copy of the registration statement in the form in which it was
declared effective by the Commission and any post-effective amendment thereto,
including financial statements and schedules, and, if the holder so requests in
writing, all exhibits (including those incorporated by reference).

                  (e)      The Company will deliver to each holder of the
Registrable Notes or the Exchange Notes included within the coverage of the
Exchange Offer or the Notes Shelf Registration, as appropriate, without charge,
as many copies of the prospectus (including each preliminary prospectus)
included in the registration statement and any amendment or supplement thereto
as such persons may reasonably request; the Company consents to the use of the
prospectus or any amendment or supplement thereto by each of the selling holders
of the Registrable Notes or the Exchange Notes in connection with the offering
and sale of the Registrable Notes or the Exchange Notes covered by the
prospectus or any amendment or supplement thereto.

<PAGE>   5



                  (f)      Prior to any public offering of the Registrable Notes
or the Exchange Notes pursuant to the Exchange Offer or the Notes Shelf
Registration, as the case may be, the Company will use its best efforts to
register or qualify, or cooperate with the holders of the Registrable Notes or
the Exchange Notes covered thereby and their respective counsel in connection
with the registration or qualification of, such Registrable Notes or Exchange
Notes for offer and sale under the securities or blue sky laws of such
jurisdictions as any seller reasonably requests in writing and do any and all
other acts or things necessary or advisable to enable the offer and sale in such
jurisdictions, of the Registrable Notes or the Exchange Notes covered by the
Exchange Offer or the Notes Shelf Registration, as the case may be; provided,
that the Company will not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or to take any action which would
subject it to general service of process or to taxation in any such jurisdiction
where it is not then so subject.

                  (g)      The Company will cooperate with the holders of the
Registrable Notes and the Exchange Notes to facilitate the timely preparation
and delivery of certificates representing the Registrable Notes and the Exchange
Notes to be sold in the Exchange Offer or the Notes Shelf Registration, as the
case may be, free of any restrictive legends and in such denominations and
registered in such names as the holders may request provided such request
complies with the Indenture, prior to sales of the Registrable Notes or the
Exchange Notes, pursuant to the Exchange Offer or the Notes Shelf Registration,
as the case may be.

                  (h)      Upon the occurrence of any event contemplated by
paragraph (b)(iv) above, the Company will prepare a post-effective amendment to
the registration statement or a supplement to the related prospectus or file any
other required document so that, as thereafter delivered to purchasers of the
Registrable Notes or the Exchange Notes, the prospectus will not contain an
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein not misleading.

                  (i)      Not later than the effective date of the applicable
registration statement, the Company will provide a CUSIP number for the
Registrable Notes or the Exchange Notes, as the case may be, and provide the
Trustee with printed certificates for the Registrable Notes or the Exchange
Notes, as the case may be, in a form eligible for deposit with The Depository
Trust Company.

                  (j)      The Company will use its best efforts to comply with
all applicable rules and regulations of the Commission and will make generally
available to its security holders an earnings statement satisfying the
provisions of Section 11(a) of the Securities Act, no later than 45 days after
the end of the 12- month period (or 90 days, if such period is a fiscal year)
beginning with the first month of the Company's first fiscal quarter commencing
after the effective date of each of the Registered Exchange Offer and the Notes
Shelf Registration, which statements shall cover such 12-month period.

                  (k)      The Company will cause the Indenture to be qualified
under the Trust Indenture Act of 1939, as amended, upon effectiveness of the
registration statement contemplated by Section 1(a) or Section 2(a).

                  (l)      The Company may require each holder of Registrable
Notes to be sold pursuant to the Notes Shelf Registration to furnish to the
Company such information regarding the holder and the distribution of such
Registrable Notes as the Company may from time to time reasonably require for
inclusion in the registration statement. The Company may exclude from such
registration the Registrable Notes of any holder who unreasonably fails to
furnish such information in writing to the Company within ten business days (or
longer time period if agreed by the Company in writing) after receiving such
request. Each holder of


                                       -5-

<PAGE>   6



Registrable Notes included within the coverage of any Registration Statement
shall furnish promptly to the Company all information required by applicable law
to be disclosed by such party in order to make the information previously
furnished to the Company not materially misleading.

                  (m)      Each holder of Registrable Notes agrees by
acquisition of such Registrable Notes or Exchange Notes to be sold that, upon
receipt of any notice from the Company of the happening of any Suspension Period
of the kind described in Section 2(b) or an event of the kind described in
Section 3(b)(ii)-(iv), such holder will forthwith discontinue disposition of
such Registrable Notes or Exchange Notes covered by such Registration Statement
or Prospectus until such holder's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 3(h) hereof or is advised in writing
by the Company that use of the prospectus may be resumed.

                  4.       Registration Expenses. The Company will bear all
expenses incurred in connection with the performance of its obligations under
Sections 1 through 3 hereof and will bear or reimburse the holders of the
Registrable Notes for the reasonable fees and disbursements of one firm of
counsel designated by the holders of a majority in principal amount of the
Registrable Notes to act as counsel for the holders of the Registrable Notes in
connection therewith; provided that in any underwritten offering the Company
shall not be obligated to pay any underwriters' discounts and commissions nor
any transfer tax related to such offering.

                  5.       Indemnification.

                  (a)      Indemnification by the Company. The Company shall 
indemnify and hold harmless (i) each Initial Purchaser, (ii) in the case of the
Notes Shelf Registration, each holder of Registrable Notes, and (iii) in the
case of the Exchange Offer, each Broker-Dealer who holds Exchange Notes acquired
for its own account pursuant to the Exchange Offer, and, in any such case, each
Initial Purchaser's and such holder's officers, directors, employees and agents
and each person who controls each such Initial Purchaser, now or hereafter, and
each such holder within the meaning of either Section 15 of the Securities Act
or Section 20 of the Exchange Act (each such person being sometimes hereinafter
referred to as an "Indemnified Person") from and against any and all losses,
claims, damages, awards, liabilities and judgments ("Losses") arising out of or
based upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus or in any amendment or
supplement thereto relating to the Notes Shelf Registration or the Exchange
Offer, as the case may be, or caused by any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading, except insofar as such Losses are caused by any such
untrue statement or omission or allegation thereof based upon information
relating to such Indemnified Person furnished in writing to the Company by such
Indemnified Person expressly for use therein and used in conformity therewith;
provided, however, that in the event an Initial Purchaser or a Broker-Dealer is
required by law to deliver a final prospectus in connection with an Exchange
Offer or a Note Shelf Registration and the indemnity obligations arising under
this Section 5(a) arise with respect to untrue statements or omissions or untrue
alleged statements or omissions made in a preliminary prospectus, such indemnity
obligations arising under this Section 5(a) shall not inure to the benefit of
any Initial Purchaser or Broker-Dealer and its controlling persons and their
respective directors, officers and employees if the person asserting any such
Losses purchased the Notes from such Initial Purchaser or Broker-Dealer and if a
copy of the final prospectus (as then amended or supplemented if the Company
shall have timely furnished any amendments thereof or supplements thereto), was
not sent or given by such Initial Purchaser or Broker-Dealer or on its behalf to
such person at or prior to the time such delivery was required by law, and if
the final prospectus (as then amended or supplemented if the Company shall have
timely furnished any amendments


                                       -6-

<PAGE>   7



thereof or supplements thereto) would have cured the defect giving rise to such
Losses. The indemnity will be in addition to any liability that the Company
otherwise may have.

                  If any action or proceeding (including any governmental
investigation or inquiry) shall be brought or asserted against an Indemnified
Person, or notice of any such claim is received, in respect of which indemnity
may be sought from the Company, such Indemnified Person shall promptly notify
the Company in writing, and the Company shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Person and the payment of all reasonable fees and expenses of such defense;
provided that the failure by any such Indemnified Person to so notify the
Company shall not relieve the Company of its indemnification obligations under
Section 5(a) hereof, except to the extent that the Company is materially
prejudiced or forfeits substantive rights and defenses by reason of such
failure. Such Indemnified Person shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be the expense of such Indemnified Person unless
(a) the Company shall have agreed in writing to pay such fees and expenses or
(b) the Company shall have failed to assume the defense of such action or
proceeding and to employ counsel reasonably satisfactory to such Indemnified
Person in any such action or proceeding within a reasonable time after notice of
commencement of such action or proceeding or (c) the named parties to any such
action or proceeding (including any impleaded parties) include such Indemnified
Person and the Company, and such Indemnified Person shall have been advised in
writing by counsel that there may be one or more legal defenses available to
such Indemnified Person that are different from or additional to those available
to the Company and in the reasonable judgment of such counsel it is advisable
for such Indemnified Party to employ separate counsel (in which case, if such
Indemnified Person notifies the Company in writing that it elects to employ
separate counsel at the expense of the Company, the Company shall not have the
right to assume the defense of such action or proceeding on behalf of such
Indemnified Person, it being understood, however, that the Company shall not, in
connection with any one such action or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to local
counsel) at any time for such Indemnified Person and any other Indemnified
Persons, which firm shall be designated in writing by such Indemnified Persons
(which shall be reasonably satisfactory to the Company), and that all such fees
and expenses shall be reimbursed as they are billed). The Company shall not be
liable for any settlement of any such action or proceeding effected without its
written consent (not to be unreasonably withheld), but if settled with its
written consent, or if there be a final, unappealable judgment for the plaintiff
in any such action or proceeding, the Company agrees to indemnify and hold
harmless such Indemnified Persons from and against any loss or liability by
reason of such settlement or judgment. The Company shall not, without the prior
written consent of the Indemnified Person (which consent shall not be
unreasonably withheld), effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is a party and indemnity
has been sought hereunder by such Indemnified Person; provided however, that the
Company may effect such a settlement without the consent of such Indemnified
Person if such settlement includes an unconditional release of such Indemnified
Person from all liability for claims that are the subject matter of such
proceeding or the Company indemnifies such Indemnified Person in writing and
posts a bond for an amount equal to the maximum liability for all such claims as
contemplated above or provide other security for such indemnity as shall be
reasonably satisfactory to such Indemnified Person.

                  (b)      Indemnification by Holders. Each holder of
Registrable Notes agrees to indemnify and hold harmless the Company, its
directors and officers, employees and agents and each person, if any,
controlling the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such holder, but only with respect to


                                       -7-

<PAGE>   8



information relating to such holder or the distribution furnished in writing by
such holder expressly for use in any registration statement or prospectus or any
amendment or supplement thereto or any preliminary prospectus relating thereto,
provided, however, that no such holder shall be liable for any indemnity claims
hereunder in excess of the amount of net proceeds received by such holder from
the sale of Registrable Notes pursuant to the Notes Shelf Registration. If any
action or proceeding shall be brought against the Company or its directors,
officers, employees or agents or any such controlling person, in respect of
which indemnity may be sought against a holder of Registrable Notes, such holder
shall have the rights and duties given the Company and the Company or its
directors, officers, employees or agents or such controlling person shall have
the rights and duties given to each holder by Section 5(a) hereof. The Company
shall be entitled to receive indemnities from underwriters, selling brokers,
dealer managers and similar securities industry professionals participating in
the distribution, to the same extent as provided above with respect to
information so furnished in writing by such persons specifically for inclusion
in any prospectus or registration statement or any amendment or supplement
thereto.

                  (c)      Contribution. If the indemnification provided for in
this Section 5 is unavailable to an indemnified party under Section 5(a) or
Section 5(b) hereof (other than by reason of exceptions provided in those
Sections) in respect of any Losses referred to therein, then each applicable
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such Losses in such proportion as is appropriate to reflect not only the
relative benefits but also the relative fault of the Company and of the
Indemnified Person in connection with the statements or omissions which resulted
in such Losses, as well as any other relevant equitable considerations. The
relative fault of the Company and of the Indemnified Person shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or by the
Indemnified Person and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the Losses referred to
above shall be deemed to include, subject to the limitations set forth in the
second paragraph of Section 5(a), any legal or other fees or expenses reasonably
incurred by such party in connection with investigating or defending any action
or claim.

                  The Company and the holders of the Registrable Notes and
Exchange Notes agree that it would not be just and equitable if contribution
pursuant to this Section 5(c) were determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

                  6.       Additional Interest Under Certain Circumstances; 
Remedies.

                  If the Company fails to file within 45 days, or cause to
become effective within 120 days, after the Closing Date, the registration
statement relating to the Exchange Offer or the Notes Shelf Registration, as
applicable, or (subject to Section 2(b)) the Notes Shelf Registration is
declared effective but thereafter ceases to be effective in connection with
resales of the Registrable Notes (each such event, a "Registration Default"),
then the Company agrees to pay to each holder of Registrable Notes, accruing
from the date of the first such Registration Default, liquidated damages in an
amount equal to one-half of one percent (0.5%) per annum of the principal amount
of Registrable Notes held by such holder during the first 180-day period
immediately following the occurrence of the first such Registration Default,
increasing by


                                       -8-

<PAGE>   9



an additional one-half of one percent (0.5%) per annum of the principal amount
of such Registrable Notes during each subsequent 180-day period, up to a maximum
amount of liquidated damages equal to two percent (2.0%) per annum of the
principal amount of such Registrable Notes ("Liquidated Damages"), and ceasing
to accrue on the date such Registration Default has been cured by, as
applicable, the filing or declaration of effectiveness of the applicable
registration statement. The Company shall notify the Trustee within one business
day after (i) each and every Registration Default and (ii) the date the
Registration Default has been so cured. Until the Trustee and the Paying Agent
have received an Officers' Certificate from the Company to the effect that all
Liquidated Damages then due have been paid in full, the Company (in respect of
any payment date) shall pay Liquidated Damages then due by depositing with the
Trustee, in trust, for the benefit of the affected holders of Registrable Notes,
on or before the applicable semi-annual interest payment date, immediately
available funds in sums sufficient to pay the Liquidated Damages then due and
provide to the Trustee and the Paying Agent a list of holders entitled to
Liquidated Damages together with the amount of cash such holder is due. The
Liquidated Damages amount due shall be payable as additional interest (from
funds received pursuant to such deposit) on each interest payment date to the
record holder of Registrable Notes entitled to receive the interest payment to
be made on such date as set forth in the Indenture.

                  7.       Miscellaneous.

                  (a)      Amendments and Waivers. The provisions of this
Agreement may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given, unless the Company
has obtained the written consent of holders of a majority in aggregate principal
amount of the Registrable Notes (insofar as such matters relate to the
Registrable Notes) or the Exchange Notes (insofar as such matters relate to the
Exchange Notes).

                  (b)      Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail, telex, telecopier, or air courier guaranteeing overnight
delivery:

                  (1)      if to a holder of Registrable Notes or Exchange
         Notes, at the most current address given by such holder to the Company
         in accordance with the provisions of this Section 7(b), which address
         initially is, with respect to each holder, the address of such holder
         to which confirmation of the sale of the Notes was first sent by an
         Initial Purchaser, with a copy in like manner to Bear, Stearns & Co.
         Inc., 245 Park Avenue, New York, New York 10167, Attention: Corporate
         Finance Department, Jefferies & Company, Inc., 11100 Santa Monica
         Boulevard, Los Angeles, California 90025, Attention: Jerry Gluck, and
         Raymond James & Associates, Inc., 880 Carillon Parkway, St. Petersburg,
         Florida 33716, Attention: Corporate Finance Department;

                  (2)      if to an Initial Purchaser, to the addresses set 
         forth in clause (b)(1) above; and

                  (3)      if to the Company, initially at its respective
         address set forth in the Purchase Agreement.

                  All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; five
business days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged by recipient's
telecopy operator, if telecopied; and on the day delivered, if sent by overnight
air courier guaranteeing next day delivery.

                  (a)      Successors and Assigns. This Agreement shall inure to
the benefit of and be binding upon the successors and assigns of each of the
parties, including without limitation and without the need for an express
assignment, subsequent holders of the Registrable Notes.

                  (b)      Counterparts. This Agreement may be executed in any
number of counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

                  (c)      Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (d)      Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, without
giving effect to principles of conflicts of laws to the extent the application
of the law of another jurisdiction would be required thereby.

                  (e)      Severability. If any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

         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

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.

To the extent that the obligations of the Company under the Indenture may be
dependent upon such matters, we assume for purposes of this opinion that the
Trustee is duly organized, validly existing and in good standing under the laws
of its jurisdiction of organization; that the Trustee is duly qualified to
engage in the activities contemplated by the Indenture; that the Indenture has
been duly authorized, executed and delivered by the Trustee and constitutes the
legally valid and binding obligation of the Trustee, enforceable against the
Trustee in accordance with its terms; that the Trustee is in compliance,
generally and with respect to acting as a trustee under the Indenture, with all
applicable laws and regulations; and that the Trustee has the requisite
organizational and legal power and authority to perform its obligations under
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.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made and entered into by and between Michael
Petroleum Corporation (the "Company"), having a business address at 13101
Northwest Freeway, Suite 320, Houston, Texas 77040, and Glenn D. Hart
("Executive"), having a mailing address at 115 Shasta Drive, Houston, Texas
77024.

         WHEREAS, the Company wishes to assure itself of the services of the
Executive for the period provided in this Agreement and the Executive wishes to
serve in the employ of the Company on the terms and conditions hereinafter
provided.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. EMPLOYMENT. Upon the terms and subject to the conditions contained
in this Agreement, the Executive agrees to provide full-time services for the
Company and its parent corporation, Michael Holdings, Inc. ("MHI") during the
term of this Agreement. The Executive agrees to devote his best efforts to the
business of the Company and MHI, and shall perform his duties in a diligent,
trustworthy, and business-like manner, all for the purpose of advancing the
business of the Company and MHI.

         2. DUTIES. The duties of the Executive shall be those duties which can
reasonably be expected to be performed by a person with the title of Chief
Executive Officer of an oil and gas exploration and production company. The
Executive shall report directly to the Board of Directors of the Company and MHI
(collectively, the "Board"). The Executive's duties may, from time to time, be
changed or modified at the discretion of the Board.

         3. EMPLOYMENT TERM. Subject to the terms and conditions hereof, the
Company agrees to employ the Executive for a term commencing as of April 1, 1998
(the "Effective Date") and continuing for two years thereafter, unless renewed
under this Section 3.

         Commencing with the calendar quarter beginning on July 1, 1998, this
Agreement shall be automatically renewed for two-year terms on the first day of
each calendar quarter, unless either the Company or the Executive provides
written notice of election not to renew, at least 30 days before the applicable
renewal date.

         4.       SALARY AND BENEFITS.

                  (a)      Base Salary.  The Company shall pay the Executive an 
initial annual base salary of $270,000 beginning on the Effective Date, pro
rated for


<PAGE>   2



         periods of less than 12 months. Such salary shall be paid in bi-monthly
         installments less applicable withholding and salary deductions. The
         Executive's base salary shall be subject to review and may be increased
         from time to time. The Company may not, however, reduce the Executive's
         base salary in effect at any time during the term of this Agreement.

                  (b) Bonus. The Company shall pay the Executive an annual bonus
         for each year during the term of this Agreement. Such bonus shall be
         paid by January 31 of each subsequent year, following the year in which
         a bonus is payable, (with the first bonus payable by January 31, 1999,
         relating to the 1998 year) during the term of this Agreement, and on or
         before the January 15 immediately following termination of this
         Agreement under Section 3 above if the Agreement terminates as a result
         of the failure to renew the Agreement by either the Company or the
         Executive. Such annual bonus shall be an amount to be determined by the
         Compensation Committee of the Board (the "Compensation Committee"), in
         its sole discretion, provided, however, that such annual bonus shall be
         not less than 50% and not greater than 100% of the Executive's base
         salary for the applicable year.

                  (c) Stock Options. In accordance with a Stock Option Plan to
         be established by MHI, the Executive shall receive options to purchase
         shares of the capital stock of MHI upon the terms and conditions and in
         such amounts as shall be determined in the sole discretion of the
         Compensation Committee.

                  (d) Vacation. The Executive shall be entitled to paid vacation
         during each full year of his employment hereunder in accordance with
         the vacation policy adopted by the Company. Such vacations shall be
         taken at such times as are consistent with the reasonable business
         needs of the Company.

                  (e) Automobile. The Company will provide the Executive with an
         automobile allowance for use by the Executive in connection with the
         performance of his duties under this Agreement. The initial automobile
         allowance shall be $1,200 per month.

                  (f) Reimbursement of Expenses. The Company shall reimburse the
         Executive for all reasonable out-of-pocket expenses incurred by the
         Executive in the course of his duties, in accordance with normal
         policies.

                  (g) Employee Benefits. The Executive shall be entitled to
         participate in the employee benefit programs generally available to
         employees of the Company, and to all normal perquisites provided to
         senior executive officers of the Company.


                                      - 2 -

<PAGE>   3



                  (h) Benefits Not in Lieu of Compensation. No benefit or
         perquisite provided to the Executive shall be deemed to be in lieu of
         base salary, bonus, or other compensation.

         5. TERMINATION OF EMPLOYMENT. The Board may terminate the employment of
the Executive at any time as it deems appropriate.

                  (a) Disability or Death. If, during the term of this
         Agreement, the Executive's employment terminates due to total
         disability (as such term is defined in Section 22(e)(3) of the Internal
         Revenue Code of 1986, as amended) or death, the Company shall pay to
         the Executive all amounts payable under Section 4(a) above during the
         remaining term of this Agreement (as provided in Section 3 above), as
         well as any bonus already accrued but unpaid to the Executive under
         Section 4(b) above, and the Company shall have no further obligation to
         make any payment under this Agreement, except as may otherwise be
         provided under the terms of any employee benefit programs in which the
         Executive is participating. The amount of base salary payable under
         this Section 5(a) shall be paid in bi-monthly installments, less
         applicable withholdings and salary deductions, and any bonus payable
         shall be paid in a lump sum, less applicable withholdings and salary
         deductions. Any amount payable under this Section 5(a) shall be paid,
         or commence to be paid, to the Executive or, in the event of the
         Executive's death, his designee under Section 16(b), as soon as
         practicable following the Executive's termination of employment. The
         Company may terminate the Executive's employment for disability if the
         Executive is incapacitated and absent from his duties hereunder on a
         full-time basis for four consecutive months or for at least 180 days
         during any 12 month period.

                  (b) Voluntary Resignation or Termination for Cause. If the
         Executive shall voluntarily terminate his employment for any reason
         other than Good Reason, as defined hereafter, or if the Company shall
         discharge the Executive for Cause, as defined hereafter, this Agreement
         shall terminate immediately and the Company shall have no further
         obligation to make any payment under this Agreement which has not
         already become payable, but has not yet been paid, except as may
         otherwise be provided under the terms of any employee benefit program
         in which the Executive is participating.

                   For the purposes of this Agreement, the Company shall have
         "Cause" to terminate the Executive's employment hereunder upon (A) the
         willful and continued failure by the Executive to perform his duties
         with the Company (other than any such failure resulting from incapacity
         due to physical or mental illness), after a demand for substantial
         performance is delivered to the Executive by the Board which
         specifically identifies the manner in which the Board believes that he
         has not substantially performed his duties, or (B) the


                                      - 3 -

<PAGE>   4



         willful engaging by the Executive in gross misconduct materially and
         demonstrably injurious to the Company. For purposes of this paragraph,
         no act, or failure to act, on the Executive's part shall be considered
         "willful" unless done, or omitted to be done, by him not in good faith
         and without reasonable belief that his action or omission was not in
         the best interest of the Company. Notwithstanding the foregoing, the
         Executive shall not be deemed to have been terminated for Cause unless
         and until there shall have been delivered to him a copy of a resolution
         duly adopted by the affirmative vote of not less than two-thirds (2/3)
         of the entire authorized membership of the Board at a meeting of the
         Board called and held for the purpose (after reasonable notice and an
         opportunity for the Executive, together with counsel, to be heard
         before the Board), finding that in the good faith opinion of the Board
         he was guilty of conduct set forth above in clauses (A) or (B) of the
         first sentence of this paragraph and specifying the particulars thereof
         in detail.

                  (c) Termination Without Cause; Resignation for Good Reason. If
         during the term of the Agreement, the Executive's employment is
         terminated by the Company without Cause or the Executive voluntarily
         terminates his employment for Good Reason:

                           (i) The Company shall continue to pay the Executive a
                  base salary as provided in Section 4(a) until the end of the
                  term of this Agreement as provided in Section 3 above;

                           (ii) The Company shall pay to the Executive in a lump
                  sum an amount equal to the value of any bonus already accrued
                  but unpaid to the Executive under Section 4(b);

                           (iii) The Executive shall have no further right to
                  receive any other compensation, or to participate in any other
                  plan, arrangement, or benefit, after such termination or
                  resignation of employment, except as may otherwise be provided
                  under the terms of any employee benefit programs in which the
                  Executive is participating.

                  For purposes of this Agreement, "Good Reason" shall mean:

                           (u) Without his express written consent, the
                  assignment to the Executive of any duties inconsistent with
                  his positions, duties, responsibilities and status with the
                  Company, or a change in his reporting responsibilities, titles
                  or offices, or any removal of the Executive from or any
                  failure to re-elect the Executive to any of such positions,
                  except in connection with the termination of his employment
                  for Cause, disability or retirement or as a result of his
                  death or by the Executive other than for Good Reason;


                                      - 4 -

<PAGE>   5



                           (v) A reduction by the Company in the Executive's
                  base salary as in effect on the date hereof or as the same may
                  be increased from time to time;

                           (w) The Company's requiring the Executive to be based
                  anywhere other than Houston, Texas, except for required travel
                  on the Company's business to an extent substantially
                  consistent with his present business travel obligations, or,
                  in the event the Executive consents to any relocation, the
                  failure by the Company to pay (or reimburse the Executive) for
                  all reasonable moving expenses incurred by him relating to a
                  change of his principal residence in connection with such
                  relocation and to indemnify the Executive against any loss
                  (defined as the difference between the actual sale price of
                  such residence and the higher of (a) his aggregate investment
                  in such residence of (b) the fair market value of such
                  residence as determined by a real estate appraiser designated
                  by the Executive and reasonably satisfactory to the Company)
                  realized on the sale of the Executive's principal residence in
                  connection with any such change of residence;

                           (x) The failure by the Company to continue in effect
                  any benefit or compensation plan (including but not limited to
                  any stock option plan, pension plan, life insurance plan,
                  health and accident plan or disability plan) in which the
                  Executive is participating (or plans providing substantially
                  similar benefits), the taking of any action by the Company
                  which would adversely affect the Executive's participation in
                  or materially reduce his benefits under any of such plans or
                  deprive him of any material fringe benefit enjoyed by him, or
                  the failure by the Company to provide the Executive with the
                  number of paid vacation days to which he is then entitled on
                  the basis of years of service with the Company in accordance
                  with the Company's normal vacation policy in effect on the
                  date hereof;

                           (y) Any failure of the Company to obtain the
                  assumption of, or the agreement to perform, this Agreement by
                  any successor as contemplated in Section 16(a) hereof; or

                           (z) Any purported termination of the Executive's
                  employment which is not effected pursuant to a notice of
                  termination satisfying the requirements of Section 5(b) above
                  (and, if applicable, Section 3 above); and for purposes of
                  this Agreement, no such purported termination shall be
                  effective.

                  (d) Mitigation of Amounts Payable Hereunder. The Executive
         shall not be required to mitigate the amount of any payment provided
         for in this Section 5 by seeking other employment or otherwise, nor
         shall the amount of any payment provided for in this Section 5 be
         reduced by any compensation earned by the Executive as the result of
         employment by another employer after the date of termination, or
         otherwise.

         6. CONFIDENTIAL INFORMATION. The Company shall provide to the Executive
initial and ongoing information of members of the Company Group, as defined
hereinafter, which information is confidential and constitutes valuable, special
and unique property of such members of the Company Group. In return, the
Executive agrees that he shall not at any time, either during or subsequent to
the term of this Agreement, disclose to others, use, copy or permit to be
copied, except in pursuance of his duties for and on behalf of the Company, it
successors, assigns or nominees, any Confidential Information, as defined
hereinafter, of any member of the Company Group (regardless of whether developed
by the Executive) without the prior written consent of the Company.

         As used herein, "Company Group" means the Company, and any entity that
directly or indirectly controls, is controlled by, or is under common control
with, the Company, and for purposes of this definition "control" means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of such entity, whether through the
ownership of voting securities, by contract or otherwise.

         The term "Confidential Information" with respect to any person means
any secret or confidential information or know-how and shall include, but shall
not be limited to, the plans, customers, costs, prices, uses, and applications
of products and services, results of investigations, studies or experiments
owned or used by such person, and all apparatus, products, processes,
compositions, samples, formulas, computer programs, computer hardware designs,
computer firmware designs, and servicing, marketing or manufacturing methods and
techniques at any time used, developed, investigated, made or sold by such
person, before or during the term of this Agreement, that are not readily
available to the public or that are maintained as confidential by such person.
The Executive shall maintain in confidence any Confidential Information of third
parties received as a result of his employment with the Company in accordance
with the Company's obligations to such third parties and the policies
established by the Company.

         7. DELIVERY OF DOCUMENTS UPON TERMINATION. The Executive shall deliver
to the Company or its designee at the termination of his employment all
correspondence, memoranda, notes, records, drawings, sketches, plans, customer
lists, product compositions, and other documents and all copies thereof, made,
composed or received by the Executive, solely or jointly with others, that are
in the Executive's


                                      - 6 -

possession, custody, or control at termination and that are related in any
manner to the past, present, or anticipated business or any member of the
Company Group. In this regard, the Executive hereby grants and conveys to the
Company all right, title and interest in and to, including without limitation,
the right to possess, print, copy, and sell or otherwise dispose of, any
reports, records, papers, summaries, photographs, drawings or other documents,
and writings, and copies, abstracts or summaries thereof, that may be prepared
by the Executive or under his direction or that may come into his possession in
any way during the term of his employment with the Company that relate in any
manner to the past, present or anticipated business of any member of the Company
Group.

         8. DISCLOSURE AND RECEIPT OF CONFIDENTIAL INFORMATION. The Executive
shall not, at any time during his employment, receive from persons not employed
by the Company, any Confidential Information, as described in Section 6 above,
not belonging to the Company, unless a valid agreement is authorized by the
Company and is signed by both the Company and by the disclosing party. The
Executive shall not use or disclose to other employees of the Company, during
his employment with the Company, Confidential Information belonging to his
former employers, former business associates, or any other third parties unless
written permission has been given by such third parties to the Company and
accepted by the Company to allow the Company to use and/or disclose such
information. The Executive shall defend and indemnify the Company Group for any
breach of the covenant contained in the preceding sentence.

         9. INTELLECTUAL PROPERTY. The Executive shall hold in trust for the
benefit of the Company, and shall disclose promptly and fully to the Company in
writing, and hereby assigns, and binds his heirs, executors, and administrators
to assign, to the Company any and all inventions, discoveries, ideas, concepts,
improvements, copyrightable works, and other developments (the "Developments")
conceived, made, discovered or developed by him, solely or jointly with others,
during the term of his employment by the Company, whether during or outside of
usual working hours and whether on the Company's premises or not, that relate in
any manner to the past, present or anticipated business of any member of the
Company Group. All works of authorship created by the Executive, solely or
jointly with others, shall be considered works made for hire under the Copyright
Act of 1976, as amended, and shall be owned entirely by the Company. Any and all
such Developments shall be the sole and exclusive property of the Company,
whether patentable, copyrightable, or neither, and the Executive shall assist
and fully cooperate in every way, at the Company's expense, in securing,
maintaining, and enforcing, for the benefit of the Company or its designee,
patents, copyrights or other types of proprietary or intellectual property
protection for such Developments in any and all countries. Within one year
following the end of the term of this Agreement and without limiting the
generality of the foregoing, any Development of the Executive relating to any
subject matter on which the Executive worked or was informed during his
employment by the Company shall


                                      - 7 -

<PAGE>   8



be conclusively presumed to have been conceived and made prior to the
termination of his employment (unless the Executive clearly proves that such
Development was conceived and made following the termination of his employment),
and shall accordingly belong and be assigned to the Company and shall be subject
to this Agreement.

         10. FURTHER ACTS. At the request of the Company (but without additional
compensation from the Company during his employment by the Company) the
Executive shall execute any and all papers and perform all lawful acts that the
Company may deem necessary or appropriate to further evidence or carry out the
transactions contemplated in this Agreement including, without limitation, such
acts as may be necessary for the preparation, filing, prosecution, and
maintenance of applications for United States letters patent and foreign letters
patent, or for United States and foreign copyright, on the Developments.

         11. NO TAMPERING. Throughout the term of the Agreement and through the
second anniversary of the expiration thereof, the Executive shall not request,
induce or attempt to influence any employee of any member of the Company Group,
as defined in Section 6, to terminate his or her employment with such member of
the Company Group.

         12. PUBLICITY AND ADVERTISING. The Executive agrees that the Company
may use his name, picture, or likeness for any advertising, publicity, or other
business purpose at any time, during the term of the Agreement by the Company
and may continue to use materials generated during the term of the Agreement for
a period of six months thereafter. Such use of the Executive's name, picture, or
likeness shall not be deemed to result in any invasion of the Executive's
privacy or in a violation of any property right the Executive may have; and the
Executive shall receive no additional consideration if his name, picture or
likeness is so used. The Executive further agrees that any negatives, prints or
other material for printing or reproduction purposes prepared in connection with
the use of his name, picture or likeness by the Company shall be and are the
sole property of the Company.

         13. REMEDIES. The Executive acknowledges that a remedy at law for any
breach or attempted breach of the Executive's obligations under Sections 6
through 12 may be inadequate, agrees that the Company may be entitled to
specific performance and injunctive and other equitable remedies in case of any
such breach or attempted breach, and further agrees to waive any requirement for
the securing or posting of any bond in connection with the obtaining of any such
injunctive or other equitable relief. The Company shall have the right to offset
against amounts to be paid to the Executive pursuant to the terms hereof any
amounts from time to time owing by the Executive to the Company. The termination
of the Agreement pursuant to Section 3, 5(a) or 5(b) shall not be deemed to be a
waiver by the Company of any breach by the Executive of this Agreement or any
other obligation


                                      - 8 -


<PAGE>   9



owed the Company, and notwithstanding such a termination the Executive shall be
liable for all damages attributable to such a breach.

         14. DISPUTE RESOLUTION. Subject to the Company's right to seek
injunctive relief in court as provided in Section 13 of this Agreement, any
dispute, controversy or claim arising out of or in relation to or connection to
this Agreement, including without limitation any dispute as to the construction,
validity, interpretation, enforceability or breach of this Agreement, shall be
exclusively and finally settled by arbitration, and any party may submit such
dispute, controversy or claim, including a claim for indemnification under this
Section 14, to arbitration.

                  (a) Arbitrators. The arbitration shall be heard and determined
         by one arbitrator, who shall be impartial and who shall be selected by
         mutual agreement of the parties; provided, however, that if the dispute
         involves more than $500,000, then the arbitration shall be heard and
         determined by three (3) arbitrators. If three (3) arbitrators are
         necessary as provided above, then (i) each side shall appoint an
         arbitrator of its choice within thirty (30) days of the submission of a
         notice of arbitration and (ii) the party-appointed arbitrators shall in
         turn appoint a presiding arbitrator of the tribunal within thirty (30)
         days following the appointment of the last party-appointed arbitrator.
         If (x) the parties cannot agree on the sole arbitrator, (y) one party
         refuses to appoint its party-appointed arbitrator within said thirty
         (30) day period or (z) the party-appointed arbitrators cannot reach
         agreement on a presiding arbitrator of the tribunal, then the
         appointing authority for the implementation of such procedure shall be
         the Senior United States District Judge for the Northern District of
         Texas, who shall appoint an independent arbitrator who does not have
         any financial interest in the dispute, controversy or claim. If the
         Senior United States District Judge for the Northern District of Texas
         refuses or fails to act as the appointing authority within ninety (90)
         days after being requested to do so, then the appointing authority
         shall be the Chief Executive Officer of the American Arbitration
         Association, who shall appoint an independent arbitrator who does not
         have any financial interest in the dispute, controversy or claim. All
         decisions and awards by the arbitration tribunal shall be made by
         majority vote.

                  (b) Proceedings. Unless otherwise expressly agreed in writing
         by the parties to the arbitration proceedings:

                           (i) The arbitration proceedings shall be held in
                  Dallas, Texas, at a site chosen by mutual agreement of the
                  parties, or if the parties cannot reach agreement on a
                  location within thirty (30) days of the appointment of the
                  last arbitrator, then at a site chosen by the arbitrators;

<PAGE>   10



                           (ii) The arbitrators shall be and remain at all times
                  wholly independent and impartial;

                           (iii) The arbitration proceedings shall be conducted
                  in accordance with the Commercial Arbitration Rules of the
                  American Arbitration Association, as amended from time to
                  time;

                           (iv) Any procedural issues not determined under the
                  arbitral rules selected pursuant to item (iii) above shall be
                  determined by the law of the place of arbitration, other than
                  those laws which would refer the matter to another
                  jurisdiction;

                           (v) The costs of the arbitration proceedings
                  (including attorneys' fees and costs) shall be borne in the
                  manner determined by the arbitrators;

                           (vi) The decision of the arbitrators shall be reduced
                  to writing; final and binding without the right of appeal; the
                  sole and exclusive remedy regarding any claims, counterclaims,
                  issues or accounting presented to the arbitrators; made and
                  promptly paid in United States dollars free of any deduction
                  or offset; and any costs or fees incident to enforcing the
                  award shall, to the maximum extent permitted by law, be
                  charged against the party resisting such enforcement;

                           (vii) The award shall include interest from the date
                  of any breach or violation of this Agreement, as determined by
                  the arbitral award, and from the date of the award until paid
                  in full, at the prime rate of Wells Fargo Bank, N.A. plus 2%
                  per annum; and

                           (viii) Judgment upon the award may be entered in any
                  court having jurisdiction over the person or the assets of the
                  party owing the judgment or application may be made to such
                  court for a judicial acceptance of the award and an order of
                  enforcement, as the case may be.

                  (c) Acknowledgment Of Parties. Each party acknowledges that he
         or she or it has voluntarily and knowingly entered into an agreement to
         arbitration under this Section by executing this Agreement.

                  Michael Holdings, Inc., a Texas corporation and the direct
         parent of the Company, by its execution hereof, guarantees the
         Company's obligations under


                                     - 10 -

         this Agreement and agrees perform the Company's obligations hereunder
         in the event the Company fails or is unable to do so.

         successor (whether direct or indirect, by purchase, merger,
         consolidation or otherwise) to all or substantially all of the business
         and/or assets of the Company, by agreement in form and substance
         satisfactory to the Executive, expressly to assume and agree to perform
         this Agreement in the same manner and to the same extent that the
         Company would be required to perform it if no such succession had taken
         place. Failure of the Company to obtain such agreement prior to the
         effectiveness of any such succession shall be a breach of this
         Agreement and shall entitle the Executive to compensation from the
         Company in the same amount and on the same terms as the Executive would
         be entitled hereunder if the Executive terminated his employment for
         Good Reason, except that for purposes of implementing the foregoing,
         the date on which any such succession becomes effective shall be deemed
         the date of termination. As used in this Agreement, "Company" shall
         mean the Company as hereinbefore defined and any successor to its
         business and/or assets as aforesaid which executes and delivers the
         agreement provided for in this Section 16 or which otherwise becomes
         bound by all the terms and provisions of this Agreement by operation of
         law.

                  (b) Executive's Heirs, etc. The Executive may not assign his
         rights or delegate his duties or obligations hereunder without the
         written consent of the Company. This Agreement shall inure to the
         benefit of and be enforceable by the Executive's personal or legal
         representatives, executors, administrators, successors, heirs,
         distributees, devisees and legatees. If the Executive should die while
         any amounts would still be payable to him hereunder as if he had
         continued to live, all such amounts, unless other provided herein,
         shall be paid in accordance with the terms of this Agreement to his
         designee or, if there be no such designee, to his estate.

                  (c) Notice. For the purposes of this Agreement, notices and
         all other communications provide for in the Agreement shall be in
         writing and shall be deemed to have been duly given when delivered or
         mailed by United States registered or certified mail, return receipt
         requested, postage prepaid, addressed to the respective addresses set
         forth on the first page of this Agreement, provided that all notices to
         the Company shall be directed to the attention of the Chief Executive
         Officer of the Company with a copy to the Secretary of the Company, or
         to such other in writing in accordance herewith, except that notices of
         change of address shall be effective only upon receipt.

                  (d) Amendment; Waiver. No provisions of this Agreement may be
         modified, waived or discharged unless such waiver, modification or
         discharge is agreed to in writing signed by the Executive and such
         officer as may be specifically designated by the Board. No waiver by
         either party hereto at any time of any breach by the other party hereto
         of, or compliance with, any condition or provision of this Agreement to
         be performed by such other party shall be deemed a waiver of similar or
         dissimilar provisions or conditions at the same or at any prior or
         subsequent time. No agreements or representations, oral or otherwise,
         express or implied, with respect to the subject matter hereof have been
         made by either party which are not set forth expressly in this
         Agreement.

                  (e) Invalid Provisions. Should any portion of this Agreement
         be adjudged or held to be invalid, unenforceable or void, such holding
         shall not have the effect of invalidating or voiding the remainder of
         this Agreement and the parties hereby agree that the portion so held
         invalid, unenforceable or void shall, if possible, be deemed amended or
         reduced in scope, or otherwise be stricken from this Agreement to the
         extent required for the purposes of validity and enforcement thereof.

                  (f) Survival of the Executive's Obligations. The Executive's
         obligations under this Agreement shall survive regardless of whether
         the Executive's employment by the Company is terminated, voluntarily or
         involuntarily, by the Company or the Executive, with or without Cause.

                  (g) Counterparts. This Agreement may be executed in one or
         more counterparts, each of which shall be deemed to be an original but
         all of which together will constitute one and the same instrument.

                  (h) Governing Law. This Agreement shall be governed by and
         construed under the laws of the State of Texas.

                  (i) Captions and Gender. The use of captions and Section
         headings herein is for purposes of convenience only and shall not
         effect the interpretation or substance of any provisions contained
         herein. Similarly, the use of the masculine gender with respect to
         pronouns in this Agreement is for purposes of convenience and includes
         either sex who may be a signatory.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made and entered into by and between Michael
Petroleum Corporation (the "Company"), having a business address at 13101
Northwest Freeway, Suite 320, Houston, Texas 77040, and Michael G. Farmar
("Executive"), having a mailing address at 6605 Mimosa Lane, Dallas, Texas
75230.

         WHEREAS, the Company wishes to assure itself of the services of the
Executive for the period provided in this Agreement and the Executive wishes to
serve in the employ of the Company on the terms and conditions hereinafter
provided.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. EMPLOYMENT. Upon the terms and subject to the conditions contained
in this Agreement, the Executive agrees to provide full-time services for the
Company and its parent corporation, Michael Holdings, Inc. ("MHI") during the
term of this Agreement. The Executive agrees to devote his best efforts to the
business of the Company and MHI, and shall perform his duties in a diligent,
trustworthy, and business-like manner, all for the purpose of advancing the
business of the Company and MHI.

         2. DUTIES. The duties of the Executive shall be those duties which can
reasonably be expected to be performed by a person with the title of President
of an oil and gas exploration and production company. The Executive shall report
directly to the Board of Directors of the Company and MHI (collectively, the
"Board"). The Executive's duties may, from time to time, be changed or modified
at the discretion of the Board.

         3. EMPLOYMENT TERM. Subject to the terms and conditions hereof, the
Company agrees to employ the Executive for a term commencing as of April 1, 1998
(the "Effective Date") and continuing for two years thereafter, unless renewed
under this Section 3.

         Commencing with the calendar quarter beginning on July 1, 1998, this
Agreement shall be automatically renewed for two-year terms on the first day of
each calendar quarter, unless either the Company or the Executive provides
written notice of election not to renew, at least 30 days before the applicable
renewal date.

         4.       SALARY AND BENEFITS.

                 (a) Base Salary. The Company shall pay the Executive an
         initial annual base salary of $180,000 beginning on the Effective
         Date, pro rated for


<PAGE>   2



         periods of less than 12 months. Such salary shall be paid in bi-monthly
         installments less applicable withholding and salary deductions. The
         Executive's base salary shall be subject to review and may be increased
         from time to time. The Company may not, however, reduce the Executive's
         base salary in effect at any time during the term of this Agreement.

                  (b) Bonus. The Company shall pay the Executive an annual bonus
         for each year during the term of this Agreement. Such bonus shall be
         paid by January 31 of each subsequent year, following the year in which
         a bonus is payable, (with the first bonus payable by January 31, 1999,
         relating to the 1998 year) during the term of this Agreement, and on or
         before the January 15 immediately following termination of this
         Agreement under Section 3 above if the Agreement terminates as a result
         of the failure to renew the Agreement by either the Company or the
         Executive. Such annual bonus shall be an amount to be determined by the
         Compensation Committee of the Board (the "Compensation Committee"), in
         its sole discretion, provided, however, that such annual bonus shall be
         not less than 50% and not greater than 100% of the Executive's base
         salary for the applicable year.

                  (c) Stock Options. In accordance with a Stock Option Plan to
         be established by MHI, the Executive shall receive options to purchase
         shares of the capital stock of MHI upon the terms and conditions and in
         such amounts as shall be determined in the sole discretion of the
         Compensation Committee.

                  (d) Vacation. The Executive shall be entitled to paid vacation
         during each full year of his employment hereunder in accordance with
         the vacation policy adopted by the Company. Such vacations shall be
         taken at such times as are consistent with the reasonable business
         needs of the Company.

                  (e) Automobile. The Company will provide the Executive with an
         automobile allowance for use by the Executive in connection with the
         performance of his duties under this Agreement. The initial automobile
         allowance shall be $1,000 per month.

                  (f) Reimbursement of Expenses. The Company shall reimburse the
         Executive for all reasonable out-of-pocket expenses incurred by the
         Executive in the course of his duties, in accordance with normal
         policies.

                  (h) Benefits Not in Lieu of Compensation. No benefit or
         perquisite provided to the Executive shall be deemed to be in lieu of
         base salary, bonus, or other compensation.

         5. TERMINATION OF EMPLOYMENT. The Board may terminate the employment of
the Executive at any time as it deems appropriate.

                  (a) Disability or Death. If, during the term of this
         Agreement, the Executive's employment terminates due to total
         disability (as such term is defined in Section 22(e)(3) of the Internal
         Revenue Code of 1986, as amended) or death, the Company shall pay to
         the Executive all amounts payable under Section 4(a) above during the
         remaining term of this Agreement (as provided in Section 3 above), as
         well as any bonus already accrued but unpaid to the Executive under
         Section 4(b) above, and the Company shall have no further obligation to
         make any payment under this Agreement, except as may otherwise be
         provided under the terms of any employee benefit programs in which the
         Executive is participating. The amount of base salary payable under
         this Section 5(a) shall be paid in bi-monthly installments, less
         applicable withholdings and salary deductions, and any bonus payable
         shall be paid in a lump sum, less applicable withholdings and salary
         deductions. Any amount payable under this Section 5(a) shall be paid,
         or commence to be paid, to the Executive or, in the event of the
         Executive's death, his designee under Section 16(b), as soon as
         practicable following the Executive's termination of employment. The
         Company may terminate the Executive's employment for disability if the
         Executive is incapacitated and absent from his duties hereunder on a
         full-time basis for four consecutive months or for at least 180 days
         during any 12 month period.

                  (b) Voluntary Resignation or Termination for Cause. If the
         Executive shall voluntarily terminate his employment for any reason
         other than Good Reason, as defined hereafter, or if the Company shall
         discharge the Executive for Cause, as defined hereafter, this Agreement
         shall terminate immediately and the Company shall have no further
         obligation to make any payment under this Agreement which has not
         already become payable, but has not yet been paid, except as may
         otherwise be provided under the terms of any employee benefit program
         in which the Executive is participating.

                   For the purposes of this Agreement, the Company shall have
         "Cause" to terminate the Executive's employment hereunder upon (A) the
         willful and continued failure by the Executive to perform his duties
         with the Company (other than any such failure resulting from incapacity
         due to physical or mental illness), after a demand for substantial
         performance is delivered to the Executive by the Board which
         specifically identifies the manner in which the Board believes that he
         has not substantially performed his duties, or (B) the


                                      - 3 -

<PAGE>   4



         willful engaging by the Executive in gross misconduct materially and
         demonstrably injurious to the Company. For purposes of this paragraph,
         no act, or failure to act, on the Executive's part shall be considered
         "willful" unless done, or omitted to be done, by him not in good faith
         and without reasonable belief that his action or omission was not in
         the best interest of the Company. Notwithstanding the foregoing, the
         Executive shall not be deemed to have been terminated for Cause unless
         and until there shall have been delivered to him a copy of a resolution
         duly adopted by the affirmative vote of not less than two-thirds (2/3)
         of the entire authorized membership of the Board at a meeting of the
         Board called and held for the purpose (after reasonable notice and an
         opportunity for the Executive, together with counsel, to be heard
         before the Board), finding that in the good faith opinion of the Board
         he was guilty of conduct set forth above in clauses (A) or (B) of the
         first sentence of this paragraph and specifying the particulars thereof
         in detail.

                  (c) Termination Without Cause; Resignation for Good Reason. If
         during the term of the Agreement, the Executive's employment is
         terminated by the Company without Cause or the Executive voluntarily
         terminates his employment for Good Reason:

                           (i) The Company shall continue to pay the Executive a
                  base salary as provided in Section 4(a) until the end of the
                  term of this Agreement as provided in Section 3 above;

                           (ii) The Company shall pay to the Executive in a lump
                  sum an amount equal to the value of any bonus already accrued
                  but unpaid to the Executive under Section 4(b);

                           (iii) The Executive shall have no further right to
                  receive any other compensation, or to participate in any other
                  plan, arrangement, or benefit, after such termination or
                  resignation of employment, except as may otherwise be provided
                  under the terms of any employee benefit programs in which the
                  Executive is participating.

                  For purposes of this Agreement, "Good Reason" shall mean:

                           (u) Without his express written consent, the
                  assignment to the Executive of any duties inconsistent with
                  his positions, duties, responsibilities and status with the
                  Company, or a change in his reporting responsibilities, titles
                  or offices, or any removal of the Executive from or any
                  failure to re-elect the Executive to any of such positions,
                  except in connection with the termination of his employment
                  for Cause, disability or retirement or as a result of his
                  death or by the Executive other than for Good Reason;


                                      - 4 -

<PAGE>   5



                           (v) A reduction by the Company in the Executive's
                  base salary as in effect on the date hereof or as the same may
                  be increased from time to time;

                           (w) The Company's requiring the Executive to be based
                  anywhere other than Dallas, Texas, except for required travel
                  on the Company's business to an extent substantially
                  consistent with his present business travel obligations, or,
                  in the event the Executive consents to any relocation, the
                  failure by the Company to pay (or reimburse the Executive) for
                  all reasonable moving expenses incurred by him relating to a
                  change of his principal residence in connection with such
                  relocation and to indemnify the Executive against any loss
                  (defined as the difference between the actual sale price of
                  such residence and the higher of (a) his aggregate investment
                  in such residence of (b) the fair market value of such
                  residence as determined by a real estate appraiser designated
                  by the Executive and reasonably satisfactory to the Company)
                  realized on the sale of the Executive's principal residence in
                  connection with any such change of residence;

                           (x) The failure by the Company to continue in effect
                  any benefit or compensation plan (including but not limited to
                  any stock option plan, pension plan, life insurance plan,
                  health and accident plan or disability plan) in which the
                  Executive is participating (or plans providing substantially
                  similar benefits), the taking of any action by the Company
                  which would adversely affect the Executive's participation in
                  or materially reduce his benefits under any of such plans or
                  deprive him of any material fringe benefit enjoyed by him, or
                  the failure by the Company to provide the Executive with the
                  number of paid vacation days to which he is then entitled on
                  the basis of years of service with the Company in accordance
                  with the Company's normal vacation policy in effect on the
                  date hereof;

                           (y) Any failure of the Company to obtain the
                  assumption of, or the agreement to perform, this Agreement by
                  any successor as contemplated in Section 16(a) hereof; or

                           (z) Any purported termination of the Executive's
                  employment which is not effected pursuant to a notice of
                  termination satisfying the requirements of Section 5(b) above
                  (and, if applicable, Section 3 above); and for purposes of
                  this Agreement, no such purported termination shall be
                  effective.

                  (d) Mitigation of Amounts Payable Hereunder. The Executive
         shall not be required to mitigate the amount of any payment provided
         for in this Section 5 by seeking other employment or otherwise, nor
         shall the amount of any payment provided for in this Section 5 be
         reduced by any compensation earned by the Executive as the result of
         employment by another employer after the date of termination, or
         otherwise.

         6. CONFIDENTIAL INFORMATION. The Company shall provide to the Executive
initial and ongoing information of members of the Company Group, as defined
hereinafter, which information is confidential and constitutes valuable, special
and unique property of such members of the Company Group. In return, the
Executive agrees that he shall not at any time, either during or subsequent to
the term of this Agreement, disclose to others, use, copy or permit to be
copied, except in pursuance of his duties for and on behalf of the Company, it
successors, assigns or nominees, any Confidential Information, as defined
hereinafter, of any member of the Company Group (regardless of whether developed
by the Executive) without the prior written consent of the Company.

         As used herein, "Company Group" means the Company, and any entity that
directly or indirectly controls, is controlled by, or is under common control
with, the Company, and for purposes of this definition "control" means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of such entity, whether through the
ownership of voting securities, by contract or otherwise.

         The term "Confidential Information" with respect to any person means
any secret or confidential information or know-how and shall include, but shall
not be limited to, the plans, customers, costs, prices, uses, and applications
of products and services, results of investigations, studies or experiments
owned or used by such person, and all apparatus, products, processes,
compositions, samples, formulas, computer programs, computer hardware designs,
computer firmware designs, and servicing, marketing or manufacturing methods and
techniques at any time used, developed, investigated, made or sold by such
person, before or during the term of this Agreement, that are not readily
available to the public or that are maintained as confidential by such person.
The Executive shall maintain in confidence any Confidential Information of third
parties received as a result of his employment with the Company in accordance
with the Company's obligations to such third parties and the policies
established by the Company.

         7. DELIVERY OF DOCUMENTS UPON TERMINATION. The Executive shall deliver
to the Company or its designee at the termination of his employment all
correspondence, memoranda, notes, records, drawings, sketches, plans, customer
lists, product compositions, and other documents and all copies thereof, made,
composed or received by the Executive, solely or jointly with others, that are
in the Executive's


                                      - 6 -

<PAGE>   7



possession, custody, or control at termination and that are related in any
manner to the past, present, or anticipated business or any member of the
Company Group. In this regard, the Executive hereby grants and conveys to the
Company all right, title and interest in and to, including without limitation,
the right to possess, print, copy, and sell or otherwise dispose of, any
reports, records, papers, summaries, photographs, drawings or other documents,
and writings, and copies, abstracts or summaries thereof, that may be prepared
by the Executive or under his direction or that may come into his possession in
any way during the term of his employment with the Company that relate in any
manner to the past, present or anticipated business of any member of the Company
Group.

         8. DISCLOSURE AND RECEIPT OF CONFIDENTIAL INFORMATION. The Executive
shall not, at any time during his employment, receive from persons not employed
by the Company, any Confidential Information, as described in Section 6 above,
not belonging to the Company, unless a valid agreement is authorized by the
Company and is signed by both the Company and by the disclosing party. The
Executive shall not use or disclose to other employees of the Company, during
his employment with the Company, Confidential Information belonging to his
former employers, former business associates, or any other third parties unless
written permission has been given by such third parties to the Company and
accepted by the Company to allow the Company to use and/or disclose such
information. The Executive shall defend and indemnify the Company Group for any
breach of the covenant contained in the preceding sentence.

         9. INTELLECTUAL PROPERTY. The Executive shall hold in trust for the
benefit of the Company, and shall disclose promptly and fully to the Company in
writing, and hereby assigns, and binds his heirs, executors, and administrators
to assign, to the Company any and all inventions, discoveries, ideas, concepts,
improvements, copyrightable works, and other developments (the "Developments")
conceived, made, discovered or developed by him, solely or jointly with others,
during the term of his employment by the Company, whether during or outside of
usual working hours and whether on the Company's premises or not, that relate in
any manner to the past, present or anticipated business of any member of the
Company Group. All works of authorship created by the Executive, solely or
jointly with others, shall be considered works made for hire under the Copyright
Act of 1976, as amended, and shall be owned entirely by the Company. Any and all
such Developments shall be the sole and exclusive property of the Company,
whether patentable, copyrightable, or neither, and the Executive shall assist
and fully cooperate in every way, at the Company's expense, in securing,
maintaining, and enforcing, for the benefit of the Company or its designee,
patents, copyrights or other types of proprietary or intellectual property
protection for such Developments in any and all countries. Within one year
following the end of the term of this Agreement and without limiting the
generality of the foregoing, any Development of the Executive relating to any
subject matter on which the Executive worked or was informed during his
employment by the Company shall


                                      - 7 -

<PAGE>   8



be conclusively presumed to have been conceived and made prior to the
termination of his employment (unless the Executive clearly proves that such
Development was conceived and made following the termination of his employment),
and shall accordingly belong and be assigned to the Company and shall be subject
to this Agreement.

         10. FURTHER ACTS. At the request of the Company (but without additional
compensation from the Company during his employment by the Company) the
Executive shall execute any and all papers and perform all lawful acts that the
Company may deem necessary or appropriate to further evidence or carry out the
transactions contemplated in this Agreement including, without limitation, such
acts as may be necessary for the preparation, filing, prosecution, and
maintenance of applications for United States letters patent and foreign letters
patent, or for United States and foreign copyright, on the Developments.

         11. NO TAMPERING. Throughout the term of the Agreement and through the
second anniversary of the expiration thereof, the Executive shall not request,
induce or attempt to influence any employee of any member of the Company Group,
as defined in Section 6, to terminate his or her employment with such member of
the Company Group.

         12. PUBLICITY AND ADVERTISING. The Executive agrees that the Company
may use his name, picture, or likeness for any advertising, publicity, or other
business purpose at any time, during the term of the Agreement by the Company
and may continue to use materials generated during the term of the Agreement for
a period of six months thereafter. Such use of the Executive's name, picture, or
likeness shall not be deemed to result in any invasion of the Executive's
privacy or in a violation of any property right the Executive may have; and the
Executive shall receive no additional consideration if his name, picture or
likeness is so used. The Executive further agrees that any negatives, prints or
other material for printing or reproduction purposes prepared in connection with
the use of his name, picture or likeness by the Company shall be and are the
sole property of the Company.

         13. REMEDIES. The Executive acknowledges that a remedy at law for any
breach or attempted breach of the Executive's obligations under Sections 6
through 12 may be inadequate, agrees that the Company may be entitled to
specific performance and injunctive and other equitable remedies in case of any
such breach or attempted breach, and further agrees to waive any requirement for
the securing or posting of any bond in connection with the obtaining of any such
injunctive or other equitable relief. The Company shall have the right to offset
against amounts to be paid to the Executive pursuant to the terms hereof any
amounts from time to time owing by the Executive to the Company. The termination
of the Agreement pursuant to Section 3, 5(a) or 5(b) shall not be deemed to be a
waiver by the Company of any breach by the Executive of this Agreement or any
other obligation


                                      - 8 -

<PAGE>   9



owed the Company, and notwithstanding such a termination the Executive shall be
liable for all damages attributable to such a breach.

         14. DISPUTE RESOLUTION. Subject to the Company's right to seek
injunctive relief in court as provided in Section 13 of this Agreement, any
dispute, controversy or claim arising out of or in relation to or connection to
this Agreement, including without limitation any dispute as to the construction,
validity, interpretation, enforceability or breach of this Agreement, shall be
exclusively and finally settled by arbitration, and any party may submit such
dispute, controversy or claim, including a claim for indemnification under this
Section 14, to arbitration.

                  (a) Arbitrators. The arbitration shall be heard and determined
         by one arbitrator, who shall be impartial and who shall be selected by
         mutual agreement of the parties; provided, however, that if the dispute
         involves more than $500,000, then the arbitration shall be heard and
         determined by three (3) arbitrators. If three (3) arbitrators are
         necessary as provided above, then (i) each side shall appoint an
         arbitrator of its choice within thirty (30) days of the submission of a
         notice of arbitration and (ii) the party-appointed arbitrators shall in
         turn appoint a presiding arbitrator of the tribunal within thirty (30)
         days following the appointment of the last party-appointed arbitrator.
         If (x) the parties cannot agree on the sole arbitrator, (y) one party
         refuses to appoint its party-appointed arbitrator within said thirty
         (30) day period or (z) the party-appointed arbitrators cannot reach
         agreement on a presiding arbitrator of the tribunal, then the
         appointing authority for the implementation of such procedure shall be
         the Senior United States District Judge for the Northern District of
         Texas, who shall appoint an independent arbitrator who does not have
         any financial interest in the dispute, controversy or claim. If the
         Senior United States District Judge for the Northern District of Texas
         refuses or fails to act as the appointing authority within ninety (90)
         days after being requested to do so, then the appointing authority
         shall be the Chief Executive Officer of the American Arbitration
         Association, who shall appoint an independent arbitrator who does not
         have any financial interest in the dispute, controversy or claim. All
         decisions and awards by the arbitration tribunal shall be made by
         majority vote.

                  (b) Proceedings. Unless otherwise expressly agreed in writing
         by the parties to the arbitration proceedings:

                           (i) The arbitration proceedings shall be held in
                  Dallas, Texas, at a site chosen by mutual agreement of the
                  parties, or if the parties cannot reach agreement on a
                  location within thirty (30) days of the appointment of the
                  last arbitrator, then at a site chosen by the arbitrators;



                                      - 9 -

<PAGE>   10



                           (ii) The arbitrators shall be and remain at all times
                  wholly independent and impartial;

                           (iii) The arbitration proceedings shall be conducted
                  in accordance with the Commercial Arbitration Rules of the
                  American Arbitration Association, as amended from time to
                  time;

                           (iv) Any procedural issues not determined under the
                  arbitral rules selected pursuant to item (iii) above shall be
                  determined by the law of the place of arbitration, other than
                  those laws which would refer the matter to another
                  jurisdiction;

                           (v) The costs of the arbitration proceedings
                  (including attorneys' fees and costs) shall be borne in the
                  manner determined by the arbitrators;

                           (vi) The decision of the arbitrators shall be reduced
                  to writing; final and binding without the right of appeal; the
                  sole and exclusive remedy regarding any claims, counterclaims,

                  Michael Holdings, Inc., a Texas corporation and the direct
         parent of the Company, by its execution hereof, guarantees the

         this Agreement and agrees perform the Company's obligations hereunder
         in the event the Company fails or is unable to do so.

         16.      MISCELLANEOUS PROVISIONS.

                  (a) Successors of the Company. The Company will require any
         successor (whether direct or indirect, by purchase, merger,
         consolidation or otherwise) to all or substantially all of the business
         and/or assets of the Company, by agreement in form and substance
         satisfactory to the Executive, expressly to assume and agree to perform
         this Agreement in the same manner and to the same extent that the
         Company would be required to perform it if no such succession had taken
         place. Failure of the Company to obtain such agreement prior to the
         effectiveness of any such succession shall be a breach of this
         Agreement and shall entitle the Executive to compensation from the
         Company in the same amount and on the same terms as the Executive would
         be entitled hereunder if the Executive terminated his employment for
         Good Reason, except that for purposes of implementing the foregoing,
         the date on which any such succession becomes effective shall be deemed
         the date of termination. As used in this Agreement, "Company" shall
         mean the Company as hereinbefore defined and any successor to its
         business and/or assets as aforesaid which executes and delivers the
         agreement provided for in this Section 16 or which otherwise becomes
         bound by all the terms and provisions of this Agreement by operation of
         law.

                  (b) Executive's Heirs, etc. The Executive may not assign his
         rights or delegate his duties or obligations hereunder without the
         written consent of the Company. This Agreement shall inure to the
         benefit of and be enforceable by the Executive's personal or legal
         representatives, executors, administrators, successors, heirs,
         distributees, devisees and legatees. If the Executive should die while
         any amounts would still be payable to him hereunder as if he had
         continued to live, all such amounts, unless other provided herein,
         shall be paid in accordance with the terms of this Agreement to his
         designee or, if there be no such designee, to his estate.

                  (c) Notice. For the purposes of this Agreement, notices and
         all other communications provide for in the Agreement shall be in
         writing and shall be deemed to have been duly given when delivered or
         mailed by United States registered or certified mail, return receipt
         requested, postage prepaid, addressed to the respective addresses set
         forth on the first page of this Agreement, provided that all notices to
         the Company shall be directed to the attention of the Chief Executive
         Officer of the Company with a copy to the Secretary of the Company, or
         to such other in writing in accordance herewith, except that notices of
         change of address shall be effective only upon receipt.

                  (d) Amendment; Waiver. No provisions of this Agreement may be
         modified, waived or discharged unless such waiver, modification or
         discharge is agreed to in writing signed by the Executive and such
         officer as may be specifically designated by the Board. No waiver by
         either party hereto at any time of any breach by the other party hereto
         of, or compliance with, any condition or provision of this Agreement to
         be performed by such other party shall be deemed a waiver of similar or
         dissimilar provisions or conditions at the same or at any prior or
         subsequent time. No agreements or representations, oral or otherwise,
         express or implied, with respect to the subject matter hereof have been
         made by either party which are not set forth expressly in this
         Agreement.

                  (e) Invalid Provisions. Should any portion of this Agreement
         be adjudged or held to be invalid, unenforceable or void, such holding
         shall not have the effect of invalidating or voiding the remainder of
         this Agreement and the parties hereby agree that the portion so held
         invalid, unenforceable or void shall, if possible, be deemed amended or
         reduced in scope, or otherwise be stricken from this Agreement to the
         extent required for the purposes of validity and enforcement thereof.

                  (f) Survival of the Executive's Obligations. The Executive's
         obligations under this Agreement shall survive regardless of whether
         the Executive's employment by the Company is terminated, voluntarily or
         involuntarily, by the Company or the Executive, with or without Cause.

                  (g) Counterparts. This Agreement may be executed in one or
         more counterparts, each of which shall be deemed to be an original but
         all of which together will constitute one and the same instrument.

                  (h) Governing Law. This Agreement shall be governed by and
         construed under the laws of the State of Texas.

                  (i) Captions and Gender. The use of captions and Section
         headings herein is for purposes of convenience only and shall not
         effect the interpretation or substance of any provisions contained
         herein. Similarly, the use of the masculine gender with respect to
         pronouns in this Agreement is for purposes of convenience and includes
         either sex who may be a signatory.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made and entered into by and between Michael
Petroleum Corporation (the "Company"), having a business address at 13101
Northwest Freeway, Suite 320, Houston, Texas 77040, and Jerry F. Holditch (the
"Executive"), having a mailing address at 18911 Heron Lane, Tomball, Texas
77375.

         WHEREAS, the Company wishes to assure itself of the services of the
Executive for the period provided in this Agreement and the Executive wishes to
serve in the employ of the Company on the terms and conditions hereinafter
provided.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. EMPLOYMENT. Upon the terms and subject to the conditions contained
in this Agreement, the Executive agrees to provide full-time services for the
Company during the term of this Agreement. The Executive agrees to devote his
best efforts to the business of the Company, and shall perform his duties in a
diligent, trustworthy, and business-like manner, all for the purpose of
advancing the business of the Company.

         2. DUTIES. The duties of the Executive shall be those duties which can
reasonably be expected to be performed by a person with the title of Vice
President of Exploration of an oil and gas exploration and production company.
The Executive shall report directly to the Chief Executive Officer of the
Company. The Executive's duties may, from time to time, be changed or modified
at the discretion of the Chief Executive Officer.

         3. EMPLOYMENT TERM. Subject to the terms and conditions hereof, the
Company agrees to employ the Executive for a term commencing as of April 1, 1998
(the "Effective Date") and continuing for two years thereafter, unless renewed
under this Section 3.

         Commencing with the calendar quarter beginning on July 1, 1998, this
Agreement shall be automatically renewed for two-year terms on the first day of
each calendar quarter, unless either the Company or the Executive provides
written notice of election not to renew, at least 30 days before the applicable
renewal date.

         4.       SALARY AND BENEFITS.

                  (a) Base Salary. The Company shall pay the Executive an
         initial annual base salary of $100,000 beginning on the Effective Date,
         pro rated for periods of less than 12 months. Such salary shall be paid
         in bi-monthly



<PAGE>   2



         installments less applicable withholding and salary deductions. The
         Executive's base salary shall be subject to review and may be increased
         from time to time. The Company may not, however, reduce the Executive's
         base salary in effect at any time during the term of this Agreement.

                  (b) Bonus. The Company shall pay the Executive an annual bonus
         for each year during the term of this Agreement. Such bonus shall be
         paid by January 31 of each subsequent year, following the year in which
         a bonus is payable, (with the first bonus payable by January 31, 1999,
         relating to the 1998 year) during the term of this Agreement, and on or
         before the January 15 immediately following termination of this
         Agreement under Section 3 above if the Agreement terminates as a result
         of the failure to renew the Agreement by either the Company or the
         Executive. Such annual bonus shall be an amount to be determined by the
         Compensation Committee of the Board of Directors of the Company (the
         "Compensation Committee"), in its sole discretion, provided, however,
         that such annual bonus shall be not less than 50% and not greater than
         100% of the Executive's base salary for the applicable year.

                  (c) Stock Options. In accordance with a stock option plan to
         be established by Michael Holdings, Inc. ("MHI"), the Executive shall
         receive options to purchase shares of the capital stock of MHI upon the
         terms and conditions and in such amounts as shall be determined in the
         sole discretion of the Compensation Committee.

                  (d) Vacation. The Executive shall be entitled to paid vacation
         during each full year of his employment hereunder in accordance with
         the vacation policy adopted by the Company. Such vacations shall be
         taken at such times as are consistent with the reasonable business
         needs of the Company.

                  (e) Automobile. The Company will provide the Executive with an
         automobile allowance for use by the Executive in connection with the
         performance of his duties under this Agreement. The initial automobile
         allowance shall be $1,000 per month.

                  (f) Reimbursement of Expenses. The Company shall reimburse the
         Executive for all reasonable out-of-pocket expenses incurred by the
         Executive in the course of his duties, in accordance with normal
         policies.

                  (g) Employee Benefits. The Executive shall be entitled to
         participate in the employee benefit programs generally available to
         employees of the Company, and to all normal perquisites provided to
         senior executive officers of the Company.

<PAGE>   3



                  (h) Benefits Not in Lieu of Compensation. No benefit or
         perquisite provided to the Executive shall be deemed to be in lieu of
         base salary, bonus, or other compensation.

         5.       TERMINATION OF EMPLOYMENT.  The Board of Directors of the 
Company (the "Board") may terminate the employment of the Executive at any time
as it deems appropriate.

                  (a) Disability or Death. If, during the term of this
         Agreement, the Executive's employment terminates due to total
         disability (as such term is defined in Section 22(e)(3) of the Internal
         Revenue Code of 1986, as amended) or death, the Company shall pay to
         the Executive all amounts payable under Section 4(a) above during the
         remaining term of this Agreement (as provided in Section 3 above), as
         well as any bonus already accrued but unpaid to the Executive under
         Section 4(b) above, and the Company shall have no further obligation to
         make any payment under this Agreement, except as may otherwise be
         provided under the terms of any employee benefit programs in which the
         Executive is participating. The amount of base salary payable under
         this Section 5(a) shall be paid in bi-monthly installments, less
         applicable withholdings and salary deductions, and any bonus payable
         shall be paid in a lump sum, less applicable withholdings and salary
         deductions. Any amount payable under this Section 5(a) shall be paid,
         or commence to be paid, to the Executive or, in the event of the
         Executive's death, his designee under Section 16(b), as soon as
         practicable following the Executive's termination of employment. The
         Company may terminate the Executive's employment for disability if the
         Executive is incapacitated and absent from his duties hereunder on a
         full-time basis for four consecutive months or for at least 180 days
         during any 12 month period.

                  (b) Voluntary Resignation or Termination for Cause. If the
         Executive shall voluntarily terminate his employment for any reason
         other than Good Reason, as defined hereafter, or if the Company shall
         discharge the Executive for Cause, as defined hereafter, this Agreement
         shall terminate immediately and the Company shall have no further
         obligation to make any payment under this Agreement which has not
         already become payable, but has not yet been paid, except as may
         otherwise be provided under the terms of any employee benefit program
         in which the Executive is participating.

                   For the purposes of this Agreement, the Company shall have
         "Cause" to terminate the Executive's employment hereunder upon (A) the
         willful and continued failure by the Executive to perform his duties
         with the Company (other than any such failure resulting from incapacity
         due to physical or mental illness), after a demand for substantial
         performance is delivered to the Executive by the Board which
         specifically identifies the manner in which the


                                      - 3 -

<PAGE>   4



         Board believes that he has not substantially performed his duties, or
         (B) the willful engaging by the Executive in gross misconduct
         materially and demonstrably injurious to the Company. For purposes of
         this paragraph, no act, or failure to act, on the Executive's part
         shall be considered "willful" unless done, or omitted to be done, by
         him not in good faith and without reasonable belief that his action or
         omission was not in the best interest of the Company. Notwithstanding
         the foregoing, the Executive shall not be deemed to have been
         terminated for Cause unless and until there shall have been delivered
         to him a copy of a resolution duly adopted by the affirmative vote of
         not less than two-thirds (2/3) of the entire authorized membership of
         the Board at a meeting of the Board called and held for the purpose
         (after reasonable notice and an opportunity for the Executive, together
         with counsel, to be heard before the Board), finding that in the good
         faith opinion of the Board he was guilty of conduct set forth above in
         clauses (A) or (B) of the first sentence of this paragraph and
         specifying the particulars thereof in detail.

                  (c) Termination Without Cause; Resignation for Good Reason. If
         during the term of the Agreement, the Executive's employment is
         terminated by the Company without Cause or the Executive voluntarily
         terminates his employment for Good Reason:

                           (i) The Company shall continue to pay the Executive a
                  base salary as provided in Section 4(a) until the end of the
                  term of this Agreement as provided in Section 3 above;

                           (ii) The Company shall pay to the Executive in a lump
                  sum an amount equal to the value of any bonus already accrued
                  but unpaid to the Executive under Section 4(b);

                           (iii) The Executive shall have no further right to
                  receive any other compensation, or to participate in any other
                  plan, arrangement, or benefit, after such termination or
                  resignation of employment, except as may otherwise be provided
                  under the terms of any employee benefit programs in which the
                  Executive is participating.

                  For purposes of this Agreement, "Good Reason" shall mean:

                           (u) Without his express written consent, the
                  assignment to the Executive of any duties inconsistent with
                  his positions, duties, responsibilities and status with the
                  Company, or a change in his reporting responsibilities, titles
                  or offices, or any removal of the Executive from or any
                  failure to re-elect the Executive to any of such positions,
                  except in connection with the termination of his employment


                                      - 4 -

<PAGE>   5



                   for Cause, disability or retirement or as a result of his
                   death or by the Executive other than for Good Reason;

                           (v) A reduction by the Company in the Executive's
                  base salary as in effect on the date hereof or as the same may
                  be increased from time to time;

                           (w) The Company's requiring the Executive to be based
                  anywhere other than Houston, Texas, except for required travel
                  on the Company's business to an extent substantially
                  consistent with his present business travel obligations, or,
                  in the event the Executive consents to any relocation, the
                  failure by the Company to pay (or reimburse the Executive) for
                  all reasonable moving expenses incurred by him relating to a
                  change of his principal residence in connection with such
                  relocation and to indemnify the Executive against any loss
                  (defined as the difference between the actual sale price of
                  such residence and the higher of (a) his aggregate investment
                  in such residence of (b) the fair market value of such
                  residence as determined by a real estate appraiser designated
                  by the Executive and reasonably satisfactory to the Company)
                  realized on the sale of the Executive's principal residence in
                  connection with any such change of residence;

                           (x) The failure by the Company to continue in effect
                  any benefit or compensation plan (including but not limited to
                  any stock option plan, pension plan, life insurance plan,
                  health and accident plan or disability plan) in which the
                  Executive is participating (or plans providing substantially
                  similar benefits), the taking of any action by the Company
                  which would adversely affect the Executive's participation in
                  or materially reduce his benefits under any of such plans or
                  deprive him of any material fringe benefit enjoyed by him, or
                  the failure by the Company to provide the Executive with the
                  number of paid vacation days to which he is then entitled on
                  the basis of years of service with the Company in accordance
                  with the Company's normal vacation policy in effect on the
                  date hereof;

                           (y) Any failure of the Company to obtain the
                  assumption of, or the agreement to perform, this Agreement by
                  any successor as contemplated in Section 16(a) hereof; or

                           (z) Any purported termination of the Executive's
                  employment which is not effected pursuant to a notice of
                  termination satisfying the requirements of Section 5(b) above
                  (and, if applicable, Section 3 above); and for purposes of
                  this Agreement, no such purported termination shall be
                  effective.

                  (d) Mitigation of Amounts Payable Hereunder. The Executive
         shall not be required to mitigate the amount of any payment provided
         for in this Section 5 by seeking other employment or otherwise, nor
         shall the amount of any payment provided for in this Section 5 be
         reduced by any compensation earned by the Executive as the result of
         employment by another employer after the date of termination, or
         otherwise.

         6. CONFIDENTIAL INFORMATION. The Company shall provide to the Executive
initial and ongoing information of members of the Company Group, as defined
hereinafter, which information is confidential and constitutes valuable, special
and unique property of such members of the Company Group. In return, the
Executive agrees that he shall not at any time, either during or subsequent to
the term of this Agreement, disclose to others, use, copy or permit to be
copied, except in pursuance of his duties for and on behalf of the Company, it
successors, assigns or nominees, any Confidential Information, as defined
hereinafter, of any member of the Company Group (regardless of whether developed
by the Executive) without the prior written consent of the Company.

         As used herein, "Company Group" means the Company, and any entity that
directly or indirectly controls, is controlled by, or is under common control
with, the Company, and for purposes of this definition "control" means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of such entity, whether through the
ownership of voting securities, by contract or otherwise.

         The term "Confidential Information" with respect to any person means
any secret or confidential information or know-how and shall include, but shall
not be limited to, the plans, customers, costs, prices, uses, and applications
of products and services, results of investigations, studies or experiments
owned or used by such person, and all apparatus, products, processes,
compositions, samples, formulas, computer programs, computer hardware designs,
computer firmware designs, and servicing, marketing or manufacturing methods and
techniques at any time used, developed, investigated, made or sold by such
person, before or during the term of this Agreement, that are not readily
available to the public or that are maintained as confidential by such person.
The Executive shall maintain in confidence any Confidential Information of third
parties received as a result of his employment with the Company in accordance
with the Company's obligations to such third parties and the policies
established by the Company.

         7. DELIVERY OF DOCUMENTS UPON TERMINATION. The Executive shall deliver
to the Company or its designee at the termination of his employment all
correspondence, memoranda, notes, records, drawings, sketches, plans, customer
lists, product compositions, and other documents and all copies thereof, made,
composed or received by the Executive, solely or jointly with others, that are
in the Executive's


                                      - 6 -

<PAGE>   7



possession, custody, or control at termination and that are related in any
manner to the past, present, or anticipated business or any member of the
Company Group. In this regard, the Executive hereby grants and conveys to the
Company all right, title and interest in and to, including without limitation,
the right to possess, print, copy, and sell or otherwise dispose of, any
reports, records, papers, summaries, photographs, drawings or other documents,
and writings, and copies, abstracts or summaries thereof, that may be prepared
by the Executive or under his direction or that may come into his possession in
any way during the term of his employment with the Company that relate in any
manner to the past, present or anticipated business of any member of the Company
Group.

         8. DISCLOSURE AND RECEIPT OF CONFIDENTIAL INFORMATION. The Executive
shall not, at any time during his employment, receive from persons not employed
by the Company, any Confidential Information, as described in Section 6 above,
not belonging to the Company, unless a valid agreement is authorized by the
Company and is signed by both the Company and by the disclosing party. The
Executive shall not use or disclose to other employees of the Company, during
his employment with the Company, Confidential Information belonging to his
former employers, former business associates, or any other third parties unless
written permission has been given by such third parties to the Company and
accepted by the Company to allow the Company to use and/or disclose such
information. The Executive shall defend and indemnify the Company Group for any
breach of the covenant contained in the preceding sentence.

         9. INTELLECTUAL PROPERTY. The Executive shall hold in trust for the
benefit of the Company, and shall disclose promptly and fully to the Company in
writing, and hereby assigns, and binds his heirs, executors, and administrators
to assign, to the Company any and all inventions, discoveries, ideas, concepts,
improvements, copyrightable works, and other developments (the "Developments")
conceived, made, discovered or developed by him, solely or jointly with others,
during the term of his employment by the Company, whether during or outside of
usual working hours and whether on the Company's premises or not, that relate in
any manner to the past, present or anticipated business of any member of the
Company Group. All works of authorship created by the Executive, solely or
jointly with others, shall be considered works made for hire under the Copyright
Act of 1976, as amended, and shall be owned entirely by the Company. Any and all
such Developments shall be the sole and exclusive property of the Company,
whether patentable, copyrightable, or neither, and the Executive shall assist
and fully cooperate in every way, at the Company's expense, in securing,
maintaining, and enforcing, for the benefit of the Company or its designee,
patents, copyrights or other types of proprietary or intellectual property
protection for such Developments in any and all countries. Within one year
following the end of the term of this Agreement and without limiting the
generality of the foregoing, any Development of the Executive relating to any
subject matter on which the Executive worked or was informed during his
employment by the Company shall


                                      - 7 -

<PAGE>   8



be conclusively presumed to have been conceived and made prior to the
termination of his employment (unless the Executive clearly proves that such
Development was conceived and made following the termination of his employment),
and shall accordingly belong and be assigned to the Company and shall be subject
to this Agreement.

         10. FURTHER ACTS. At the request of the Company (but without additional
compensation from the Company during his employment by the Company) the
Executive shall execute any and all papers and perform all lawful acts that the
Company may deem necessary or appropriate to further evidence or carry out the
transactions contemplated in this Agreement including, without limitation, such
acts as may be necessary for the preparation, filing, prosecution, and
maintenance of applications for United States letters patent and foreign letters
patent, or for United States and foreign copyright, on the Developments.

         11. NO TAMPERING. Throughout the term of the Agreement and through the
second anniversary of the expiration thereof, the Executive shall not request,
induce or attempt to influence any employee of any member of the Company Group,
as defined in Section 6, to terminate his or her employment with such member of
the Company Group.

         12. PUBLICITY AND ADVERTISING. The Executive agrees that the Company
may use his name, picture, or likeness for any advertising, publicity, or other
business purpose at any time, during the term of the Agreement by the Company
and may continue to use materials generated during the term of the Agreement for
a period of six months thereafter. Such use of the Executive's name, picture, or
likeness shall not be deemed to result in any invasion of the Executive's
privacy or in a violation of any property right the Executive may have; and the
Executive shall receive no additional consideration if his name, picture or
likeness is so used. The Executive further agrees that any negatives, prints or
other material for printing or reproduction purposes prepared in connection with
the use of his name, picture or likeness by the Company shall be and are the
sole property of the Company.

         13. REMEDIES. The Executive acknowledges that a remedy at law for any
breach or attempted breach of the Executive's obligations under Sections 6
through 12 may be inadequate, agrees that the Company may be entitled to
specific performance and injunctive and other equitable remedies in case of any
such breach or attempted breach, and further agrees to waive any requirement for
the securing or posting of any bond in connection with the obtaining of any such
injunctive or other equitable relief. The Company shall have the right to offset
against amounts to be paid to the Executive pursuant to the terms hereof any
amounts from time to time owing by the Executive to the Company. The termination
of the Agreement pursuant to Section 3, 5(a) or 5(b) shall not be deemed to be a
waiver by the Company of any breach by the Executive of this Agreement or any
other obligation


                                      - 8 -

<PAGE>   9



owed the Company, and notwithstanding such a termination the Executive shall be
liable for all damages attributable to such a breach.

         14. DISPUTE RESOLUTION. Subject to the Company's right to seek
injunctive relief in court as provided in Section 13 of this Agreement, any
dispute, controversy or claim arising out of or in relation to or connection to
this Agreement, including without limitation any dispute as to the construction,
validity, interpretation, enforceability or breach of this Agreement, shall be
exclusively and finally settled by arbitration, and any party may submit such
dispute, controversy or claim, including a claim for indemnification under this
Section 14, to arbitration.

                  (a) Arbitrators. The arbitration shall be heard and determined
         by one arbitrator, who shall be impartial and who shall be selected by
         mutual agreement of the parties; provided, however, that if the dispute
         involves more than $500,000, then the arbitration shall be heard and
         determined by three (3) arbitrators. If three (3) arbitrators are
         necessary as provided above, then (i) each side shall appoint an
         arbitrator of its choice within thirty (30) days of the submission of a
         notice of arbitration and (ii) the party-appointed arbitrators shall in
         turn appoint a presiding arbitrator of the tribunal within thirty (30)
         days following the appointment of the last party-appointed arbitrator.
         If (x) the parties cannot agree on the sole arbitrator, (y) one party
         refuses to appoint its party-appointed arbitrator within said thirty
         (30) day period or (z) the party-appointed arbitrators cannot reach
         agreement on a presiding arbitrator of the tribunal, then the
         appointing authority for the implementation of such procedure shall be
         the Senior United States District Judge for the Northern District of
         Texas, who shall appoint an independent arbitrator who does not have
         any financial interest in the dispute, controversy or claim. If the
         Senior United States District Judge for the Northern District of Texas
         refuses or fails to act as the appointing authority within ninety (90)
         days after being requested to do so, then the appointing authority
         shall be the Chief Executive Officer of the American Arbitration
         Association, who shall appoint an independent arbitrator who does not
         have any financial interest in the dispute, controversy or claim. All
         decisions and awards by the arbitration tribunal shall be made by
         majority vote.

                  (b) Proceedings. Unless otherwise expressly agreed in writing
         by the parties to the arbitration proceedings:

                           (i) The arbitration proceedings shall be held in
                  Dallas, Texas, at a site chosen by mutual agreement of the
                  parties, or if the parties cannot reach agreement on a
                  location within thirty (30) days of the appointment of the
                  last arbitrator, then at a site chosen by the arbitrators;

<PAGE>   10



                           (ii) The arbitrators shall be and remain at all times
                  wholly independent and impartial;

                           (iii) The arbitration proceedings shall be conducted
                  in accordance with the Commercial Arbitration Rules of the
                  American Arbitration Association, as amended from time to
                  time;

                           (iv) Any procedural issues not determined under the
                  arbitral rules selected pursuant to item (iii) above shall be
                  determined by the law of the place of arbitration, other than
                  those laws which would refer the matter to another
                  jurisdiction;

                           (v) The costs of the arbitration proceedings
                  (including attorneys' fees and costs) shall be borne in the
                  manner determined by the arbitrators;

                           (vi) The decision of the arbitrators shall be reduced
                  to writing; final and binding without the right of appeal; the
                  sole and exclusive remedy regarding any claims, counterclaims,
                  issues or accounting presented to the arbitrators; made and
                  promptly paid in United States dollars free of any deduction
                  or offset; and any costs or fees incident to enforcing the
                  award shall, to the maximum extent permitted by law, be
                  charged against the party resisting such enforcement;

                           (vii) The award shall include interest from the date
                  of any breach or violation of this Agreement, as determined by
                  the arbitral award, and from the date of the award until paid
                  in full, at the prime rate of Wells Fargo Bank, N.A. plus 2%
                  per annum; and

                           (viii) Judgment upon the award may be entered in any
                  court having jurisdiction over the person or the assets of the
                  party owing the judgment or application may be made to such
                  court for a judicial acceptance of the award and an order of
                  enforcement, as the case may be.

                  (c) Acknowledgment Of Parties. Each party acknowledges that he
         or she or it has voluntarily and knowingly entered into an agreement to
         arbitration under this Section by executing this Agreement.

         15.      GUARANTEE.

                  Michael Holdings, Inc., a Texas corporation and the direct
parent of the Company, by its execution hereof, guarantees the Company's
obligations under


                                     - 10 -

         this Agreement and agrees perform the Company's obligations hereunder
         in the event the Company fails or is unable to do so.

         16.      MISCELLANEOUS PROVISIONS.

                  (a) Successors of the Company. The Company will require any
         successor (whether direct or indirect, by purchase, merger,
         consolidation or otherwise) to all or substantially all of the business
         and/or assets of the Company, by agreement in form and substance
         satisfactory to the Executive, expressly to assume and agree to perform
         this Agreement in the same manner and to the same extent that the
         Company would be required to perform it if no such succession had taken
         place. Failure of the Company to obtain such agreement prior to the
         effectiveness of any such succession shall be a breach of this
         Agreement and shall entitle the Executive to compensation from the
         Company in the same amount and on the same terms as the Executive would
         be entitled hereunder if the Executive terminated his employment for
         Good Reason, except that for purposes of implementing the foregoing,
         the date on which any such succession becomes effective shall be deemed
         the date of termination. As used in this Agreement, "Company" shall
         mean the Company as hereinbefore defined and any successor to its
         business and/or assets as aforesaid which executes and delivers the
         agreement provided for in this Section 16 or which otherwise becomes
         bound by all the terms and provisions of this Agreement by operation of
         law.

                  (b) Executive's Heirs, etc. The Executive may not assign his
         rights or delegate his duties or obligations hereunder without the
         written consent of the Company. This Agreement shall inure to the
         benefit of and be enforceable by the Executive's personal or legal
         representatives, executors, administrators, successors, heirs,
         distributees, devisees and legatees. If the Executive should die while
         any amounts would still be payable to him hereunder as if he had
         continued to live, all such amounts, unless other provided herein,
         shall be paid in accordance with the terms of this Agreement to his
         designee or, if there be no such designee, to his estate.

                  (c) Notice. For the purposes of this Agreement, notices and
         all other communications provide for in the Agreement shall be in
         writing and shall be deemed to have been duly given when delivered or
         mailed by United States registered or certified mail, return receipt
         requested, postage prepaid, addressed to the respective addresses set
         forth on the first page of this Agreement, provided that all notices to
         the Company shall be directed to the attention of the Chief Executive
         Officer of the Company with a copy to the Secretary of the Company, or
         to such other in writing in accordance herewith, except that notices of
         change of address shall be effective only upon receipt.

                  (d) Amendment; Waiver. No provisions of this Agreement may be
         modified, waived or discharged unless such waiver, modification or
         discharge is agreed to in writing signed by the Executive and such
         officer as may be specifically designated by the Board. No waiver by
         either party hereto at any time of any breach by the other party hereto
         of, or compliance with, any condition or provision of this Agreement to
         be performed by such other party shall be deemed a waiver of similar or
         dissimilar provisions or conditions at the same or at any prior or
         subsequent time. No agreements or representations, oral or otherwise,
         express or implied, with respect to the subject matter hereof have been
         made by either party which are not set forth expressly in this
         Agreement.

                  (e) Invalid Provisions. Should any portion of this Agreement
         be adjudged or held to be invalid, unenforceable or void, such holding
         shall not have the effect of invalidating or voiding the remainder of
         this Agreement and the parties hereby agree that the portion so held
         invalid, unenforceable or void shall, if possible, be deemed amended or
         reduced in scope, or otherwise be stricken from this Agreement to the
         extent required for the purposes of validity and enforcement thereof.

                  (f) Survival of the Executive's Obligations. The Executive's
         obligations under this Agreement shall survive regardless of whether
         the Executive's employment by the Company is terminated, voluntarily or
         involuntarily, by the Company or the Executive, with or without Cause.

                  (g) Counterparts. This Agreement may be executed in one or
         more counterparts, each of which shall be deemed to be an original but
         all of which together will constitute one and the same instrument.

                  (h) Governing Law. This Agreement shall be governed by and
         construed under the laws of the State of Texas.

                  (i) Captions and Gender. The use of captions and Section
         headings herein is for purposes of convenience only and shall not
         effect the interpretation or substance of any provisions contained
         herein. Similarly, the use of the masculine gender with respect to
         pronouns in this Agreement is for purposes of convenience and includes
         either sex who may be a signatory.

                           PURCHASE AND SALE AGREEMENT

     THIS AGREEMENT (this "Agreement"), dated February 20, 1998, is by and
between CONOCO INC., a Delaware corporation ("Conoco"), and MICHAEL PETROLEUM
CORPORATION, a Texas corporation ("Michael"), and is in consideration of
Conoco's agreement to sell, and Michael's agreement to buy, certain property
described in this Agreement, all pursuant to the terms and conditions of this
Agreement. Conoco and Michael may also be referred to herein individually as a
"Party" or, collectively, as the "Parties."

     1. PROPERTY. Subject to the terms and conditions set forth hereinafter, and
except for the "Excluded Property" as defined in Section 2 below, Conoco agrees
to grant or convey to Michael (whichever is applicable as provided for below)
the Conoco Property (as defined hereinafter) and Michael agrees to accept the
Conoco Property, and tender consideration therefor, in the manner and of the
type and amount as hereinafter required. For purposes of this Agreement, "Conoco
Property" shall mean, collectively:

     (a) all of Conoco's right, title and interest in, to and under or derived
from the oil and gas leases, surface estate, and other interests therein
referred to in Exhibit A-1, attached hereto and made a part hereof for all
purposes (the "Leases"), insofar and only insofar as the Leases apply to the
lands, depths, formations, wellbore rights and/or other rights specified on
Exhibit A-1 together with identical interests in and to all property and rights
incident thereto, including, without limitation, all wells (whether producing,
non-producing or abandoned), water source, water injection and other injection
or disposal wells and systems, gathering systems, materials, equipment, personal
property, fixtures and facilities located on the Leases or used in connection
with the Leases and all of Conoco's rights in, to and under all agreements,
unitization agreements, operating agreements, processing agreements,
transportation agreements, production sale agreements, leases, permits,
rights-of-way, easements, licenses, options and orders identified in Exhibit D,
insofar as they pertain to the interests in the Leases transferred to Michael
hereunder; and

     (b) a leasehold interest in all of Conoco's right, title and interest in,
to and under or derived from the lands depicted on the plat attached hereto as
Exhibit B (the "South Callaghan Ranch Lands"), insofar and only insofar as the
South Callaghan Ranch Lands cover the interval from the surface of the ground
down to 100 feet below the stratigraphic equivalent of the base of the Lobo 6
sand, together with all of Conoco's right, title and interest in and to all
wells (whether producing, non-producing or abandoned), water source, water
injection and other injection or disposal wells and systems, gathering systems,
materials, equipment, personal property, fixtures and facilities located on the
South Callaghan Ranch Lands and used in connection with hydrocarbon production
from such lands and the above-described depths and all agreements, unitization
agreements, operating agreements, processing agreements, transportation
agreements, production sale agreements, leases, permits, rights-of-way,
easements, licenses, options and orders relating to such lands and
above-described depths and identified in Exhibit D, all pursuant to an Oil and
Gas Lease from Conoco to Michael in substantially the form of lease attached
hereto as Exhibit C-2 (the "South Callaghan Ranch Lease").

tests) belonging to Conoco or licensed from third parties, and (ii)
interpretations of seismic, geological, geochemical or geophysical data

     (b) Conoco's right, title and interest in any agreements, unitization

from the Conoco Property in Exhibit D;

     (c) Conoco's corporate, financial and tax records, legal files and any

Property after the Effective Time;

     (d) claims of Conoco for refund of or loss carry forwards with respect to
(i) production, windfall profit, severance, ad valorem or any other taxes

  3. CONSIDERATION.

     (a) Purchase Price. As consideration for the Conoco Property, Michael shall
pay to Conoco at Closing (as defined hereinafter), the cash sum of TWENTY-THREE
MILLION THREE HUNDRED THOUSAND AND NO/100 DOLLARS ($23,300,000) (the "Purchase
Price"). The Purchase Price will be subject to the upward and downward
adjustments hereafter provided in this Agreement. The Purchase Price will be
allocated among the various portions of the Conoco Property and among
depreciable assets and nondepreciable assets as provided in Exhibit A-3.

     (b) Reporting Value. Neither Party will take any position in preparing
financial statements, tax returns, reports to shareholders or governmental
authorities, or otherwise, that is inconsistent with the value assigned to each
portion of the Conoco Property in Exhibit A-3, unless the Parties otherwise
agree in writing.

     (c) Section 1031 Exchange. Conoco and Michael hereby agree that Conoco will
have the right at any time prior to Closing to assign all or a portion of its
rights under this Agreement to a Qualified Intermediary (as that term is defined
in Section 1.1031(k)- 1(g)(4)(v) of the Treasury Regulations) in order to
accomplish the transaction in a manner that will comply, either in whole or in
part, with the requirements of a like-kind exchange pursuant to Section 1031 of
the Internal Revenue Code of 1986, as amended, (the "Code"). If Conoco assigns
all or part of its rights under this Agreement pursuant to this Section 3(c),
Conoco will notify Michael in writing of such assignment at or before Closing,
and Michael agrees to (i) consent to Conoco's assignment of its rights in this
Agreement in form attached hereto as Exhibit F, and (ii) pay the Purchase Price
into a qualified escrow or qualified trust account at Closing as directed in
writing. Conoco and Michael acknowledge and agree that any assignment of this
Agreement to a Qualified Intermediary shall not release Conoco from any of
Conoco's liabilities and obligations to Michael under this Agreement.

     4. MICHAEL PRE-ACQUISITION REVIEW. Conoco shall make a good-faith effort to
give Michael and Michael's authorized representatives, at any reasonable time(s)
before Closing, (a) physical access to the wells and other equipment included in
the Conoco Property, at Michael's sole risk, cost and expense, for the purpose
of inspecting the same, and conducting witnessed tests of production from the
wells thereon, (b) access to all production, engineering and other technical
data and records, and to all contract, land and lease records, to the extent
such data and records are in Conoco's possession and relate to the Conoco
Property, and (c) access to all Conoco accounting records pertaining to the
Conoco Property for the past three (3) years such that Michael can perform an
audit of such records for such three (3) year period prior to the Closing Date;
provided, however, Conoco shall have no obligation to provide Michael such
access to any data or information which Conoco considers proprietary or
confidential, which is not in Conoco's possession, or which access Conoco cannot
legally provide Michael because of third-party restrictions.

  5. TITLE DEFECTS IN CONOCO PROPERTY.

     (a) Definition of Title Defect. As used in this Agreement, the term "Title
Defect" shall mean a material deficiency in one (or more) of the following
respects:

          (i) Conoco's title, as of the Effective Time (as defined hereinafter),
as to all or any portion of the Conoco Property, is subject to an outstanding
mortgage, deed of trust, lien or encumbrance or other adverse claim which would
interfere materially with the ownership, operation, use or value of the Conoco
Property;

          (ii) Conoco owns less than the net revenue interest described on
Exhibit A-2 or more than the working interest described on Exhibit A-2 without a
corresponding increase in net revenue interest;

          (iii) Conoco's rights and interests are subject to being reduced by
virtue of the exercise by a third party of any preferential right, reversionary,
back-in or other similar right not reflected on Exhibit A-2; and

          (iv) Conoco is in material default under some material provision of a
lease, farmout agreement, operating agreement, or other agreement affecting the
Conoco Property.

     (b) Notice of Title Defects. Michael shall give Conoco written notice of
each Title Defect on or before five (5) days prior to the Closing Date, together
with full particulars relating thereto. MICHAEL SHALL BE DEEMED TO HAVE WAIVED
ALL TITLE DEFECTS OF WHICH CONOCO HAS NOT BEEN GIVEN TIMELY WRITTEN NOTICE AS
PROVIDED IN THIS SECTION 5, SAVE AND EXCEPT CLAIMS BASED UPON A BREACH OF THE
LIMITED WARRANTY OF TITLE PROVIDED IN THE ASSIGNMENT AND BILL OF SALE ATTACHED
HERETO AS EXHIBIT C-1 AND THE SOUTH CALLAGHAN RANCH LEASE ATTACHED HERETO AS
EXHIBIT C-2. HOWEVER, SUCH LIMITED WARRANTY OF TITLE WILL EXTEND ONLY TO TITLE
DEFECTS THAT BECOME KNOWN TO MICHAEL AFTER THE CLOSING DATE.

     (c) Interest Additions. Conoco may, by delivery of written notice to
Michael on or before five (5) days prior to Closing, request an increase in the
Purchase Price for the value of any net revenue interest owned by Conoco in the
Conoco Property that is greater than that shown on Exhibit A-2. Any such notice
by Conoco shall include all appropriate evidence to substantiate its position.
If Conoco and Michael are unable to agree on the amount of the Purchase Price
increase for any such increase in Conoco's net revenue interest in the Conoco
Property, Conoco at its sole option may either (i) waive any Purchase Price
increase for the additional interest, or (ii) terminate this Agreement by giving
written notice to Michael prior to the Closing Date, in which event this
Agreement shall be of no further force and effect and neither Party shall have
any further liability or obligation to the other Party under this Agreement. If
any such notice is not timely delivered, Conoco shall have no right to request a
Purchase Price increase in connection with the additional interest claimed in
the notice.

  6. REMEDIES FOR TITLE DEFECTS.

     (a) Remedies of Title Defects. Upon timely delivery of a notice by Michael
of a Title Defect in the Conoco Property under Section 5, Michael and Conoco
shall meet, within the period between the date of receipt of such notice and the
Closing Date, and may mutually agree to one of the following remedies with
respect to the Title Defect: (i) that Conoco shall cure or agree to cure such
Title Defect, to the extent agreed upon prior to Closing (provided, however,
Conoco shall have no obligation to perform such cure), (ii) that Michael shall
accept the interest subject to the Title Defect "AS IS," and release Conoco from
all claims related to such Title Defect, (iii) that Conoco shall indemnify
Michael against all losses, costs, expenses and liabilities with respect to such
Title Defect, or (iv) that Conoco and Michael shall adjust the Purchase Price by
an amount equal to the value of such Title Defect, as agreed by Conoco and
Michael.

     (b) Termination Rights. Either Party, by written notice to the other Party
prior to the Closing Date, shall have the right to terminate this Agreement upon
the occurrence of one or more of the following events: (i) if Conoco and Michael
are unable to agree prior to the Closing Date on the remedy (including the
amount of any Purchase Price adjustment) for any Title Defect of which Conoco
has been properly notified as provided in Section 5, or (ii) if the net amount
of the Purchase Price adjustments hereunder for Title Defects exceeds ten
percent (10%) of the Purchase Price. If either Party exercises its right to
terminate this Agreement due to one of the foregoing events, this Agreement will
be of no further force and effect and neither Party will have any further
liability or obligation to the other Party under this Agreement.

     (c) Post-Closing Reimbursement of Purchase Price Adjustments. If Michael
receives a Purchase Price adjustment at Closing on account of a Title Defect,
Conoco shall have until June 30, 1998 to cure such Title Defect at Conoco's
cost. If by such date Conoco can demonstrate to Michael's reasonable
satisfaction that such Title Defect has been cured, then Conoco shall be
entitled to reimbursement from Michael for the amount of the Purchase Price
adjustment for such Title Defect. Michael shall pay such amount to Conoco within
fifteen (15) Business Days of the date Conoco demonstrates to Michael's
reasonable satisfaction that such Title Defect has been cured.

     (d) Exclusive Remedy. The remedies set forth in this Section 6 are the
exclusive remedies under this Agreement for all Title Defect matters known to
Michael on or before the Closing Date, and, except as provided in this Section
6, Conoco shall have no liability to Michael with respect to such Title Defects
in the Conoco Property. Conoco's limited warranty of title in the conveyance
instruments for the Conoco Property will be the exclusive remedy for any Title
Defects in the Conoco Property that become known to Michael after the Closing
Date.

  7. GAS IMBALANCES FOR CONOCO PROPERTY. Michael shall assume all gas 
imbalances that may exist with respect to production from the Conoco Property,
regardless of whether any such gas imbalances are attributable to production
from the Conoco Property before or after the Effective Time. There will be no
increase or decrease in the Purchase Price for any



                                      -5-
<PAGE>   11

such gas imbalances. On and after Closing, all rights and obligations with
respect to all such gas imbalances will be an Assumed Obligation of Michael.

  8. REPRESENTATIONS BY CONOCO. Conoco represents to Michael, each of which
representations shall survive Closing, that as of the date of this Agreement and
as of Closing:

     (a) Due Organization. Conoco is a corporation duly organized, validly
existing, and in good standing under the laws of the state of Delaware and is
duly qualified to do business in the State of Texas and has satisfied all state
bonding requirements, if any.

     (b) Corporate Power. Conoco has all requisite corporate power and authority
to carry on its business as presently conducted, to enter into this Agreement,
and to perform its obligations under this Agreement. The consummation of the
transactions contemplated by this Agreement will not violate, nor be in conflict
with, (i) any provision of its charter or bylaws or (ii) any agreement or
instrument to which it is a party or is bound (except for preferential rights to
purchase, maintenance of uniform interests, and required third party consents to
assignment, if any).

     (c) Duly Executed. This Agreement has been duly executed and delivered on
behalf of Conoco, and at Closing all documents and instruments required
hereunder to be executed and delivered by it shall have been duly executed and
delivered and the transactions contemplated hereby shall have been duly and
validly authorized by all requisite corporate action.

     (d) No Restraining Litigation. There are no pending or, to the best of
Conoco's knowledge without further investigation, threatened claims, lawsuits,
administrative proceedings, or governmental investigations or inquiries

<PAGE>   17


Michael acknowledge that some items in the Preliminary Settlement Statement may
be estimates or otherwise subject to change in the final settlement statement
for the Property to be prepared pursuant to Section 18. The term "Business Day"

     (b) Upward Adjustments. The Purchase Price will be increased by the
following expenses and revenues related to the Conoco Property:

         (i) to the extent paid or incurred by Conoco, all actual production
expenses, operating expenses, overhead charges under applicable operating
agreements, capital expenditures, and other costs and expenses relating to the
ownership or operation of the Conoco Property (including royalties, minimum
royalties, rentals, and prepaid charges), to the extent they are attributable to
the period from and after the Effective Time;

         (ii) any proceeds from the sale of hydrocarbon production and other
income from the Conoco Property received by Michael, to the extent attributable
to the period before the Effective Time;

         (iii) any other increases in the Purchase Price specified in this
Agreement or otherwise agreed in writing between Conoco and Michael prior to or
at Closing.

     (c) Downward Adjustments. The Purchase Price will be decreased by the

deduction of any royalties under the applicable pricing provisions on any oil,
gas and gas plant liquids sales and processing agreements) and other income
received by Conoco, to the extent attributable to the Conoco Property and the
period from and after the Effective Time;

         (iii) any other decreases in the Purchase Price specified in this
Agreement or otherwise agreed in writing between Conoco and Michael prior to or
at Closing.

  18. POST-CLOSING ACCOUNTING ON CONOCO PROPERTY.

     (a) Determination of Final Purchase Price. As soon as practicable after the
Closing, Conoco shall prepare and deliver to Michael, in accordance with this
Agreement and generally accepted accounting principles, a statement (the
"Intermediate Settlement Statement") setting forth for the Conoco Property each
adjustment or payment that was not finally determined



                                      -12-
<PAGE>   18


as of the Closing in connection with the Conoco Property and showing the
calculation of such adjustments to the Purchase Price. As soon as practicable
after receipt of the Intermediate Settlement Statement, Michael shall deliver to
Conoco a written report containing any changes that Michael proposes be made to
such Intermediate Settlement Statement. The Parties undertake to agree with
respect to such Intermediate Settlement Statement no later than 90 days after
the Closing Date, such agreement constituting and to be embodied in a "Final
Settlement Statement" and to establish the "Final Purchase Price," and the date
upon which the Final Purchase Price is established to be the "Final Settlement
Date." In the event Michael and Conoco are unable to mutually agree upon the
amount of the Final Settlement Statement in connection with the Conoco Property,
an audit shall be conducted by a mutually agreed upon accounting firm. Michael
and Conoco agree to be bound by the findings of such audit, insofar as the Final
Settlement Statement amount is concerned, and each shall bear one half of all
expenses associated with such audit. In the event that (a) the Final Purchase
Price is more than the amount paid at Closing, Michael shall pay to Conoco the
amount of such difference, or (b) the Final Purchase Price is less than the
amount paid at Closing, Conoco shall pay to Michael the amount of such
difference, in either event by wire transfer in immediately available funds, or,
if the amount of such difference is less than $25,000, by corporate check,
within 10 Business Days after the amount due is finally determined.

     (b) Post-Closing Joint Interest Audit Adjustments. In connection with the
Conoco Property, Conoco shall be responsible for the settlement of all joint
billing audits which relate to accounting periods prior to the Effective Time
and Michael shall be responsible for the settlement of all joint billing audits
which relate to accounting periods after the Effective Time. Any credits
received by Michael after the Effective Time attributable to expenses paid by
Conoco for periods prior to the Effective Time on behalf of the Conoco Property
shall be promptly reimbursed to Conoco by Michael. Any credits received by
Conoco after the Effective Time attributable to expenses paid by Michael for
periods after the Effective Time on behalf of the Conoco Property shall be
promptly reimbursed to Michael by Conoco.

     (c) Other Post-Closing Revenues and Expenses. After the determination of
the Final Purchase Price under this Section 18, (i) if either Party receives
revenues that belong to the other Party under this Agreement, the Party
receiving the revenues agrees to promptly remit those revenues to the other
Party, and (ii) if either Party pays expenses that are the responsibility of the
other Party under this Agreement, the Party on whose behalf the expenses were
paid agrees to promptly reimburse the other Party for the expenses paid on its
behalf upon receiving satisfactory evidence of such payment. However, neither
Party will be obligated to reimburse the other Party for any such expense in
excess of $5,000 unless it has been consulted about that expense prior to
payment and has authorized such payment, unless that payment was required by a
government agency or other government entity.

  19. TAXES AND EXPENSES.

     (a) Recording Expenses. Michael shall pay for all recording, filing and
transfer fees, stamps and taxes in connection with the recording of the
conveyance documents and the transfer of the Conoco Property pursuant to this
Agreement, all other state and federal transfer




                                      -13-

transfer of the Property.

     (b) Ad Valorem, Real Property and Personal Property Taxes. All Ad Valorem
Taxes, Real Property Taxes, Personal Property Taxes, and similar obligations
("Property Taxes") on the Conoco Property are Conoco's obligation for periods
before the Effective Time and Michael's obligation for periods after the
Effective Time. If Property Taxes for the current tax year have not been
assessed and paid as of the Closing Date, Michael shall file all required
reports and returns incident to the Property Taxes and pay the Property Taxes
for the current tax year and subsequent periods. Conoco will reimburse Michael
promptly for Conoco's proportionate share of these taxes, prorated as of the
Effective Time, upon receipt of evidence of Michael's payment of the taxes. If
Property Taxes for the current tax year have been assessed and paid as of the
Closing Date, Michael will reimburse Conoco for its proportionate share of these
taxes, prorated as of the Effective Time, as a closing adjustment to the
Purchase Price, as provided in Section 17 of this Agreement.

     (c) Severance Taxes. Conoco shall bear and pay all severance, production,
excise or other taxes measured by hydrocarbon production from the Conoco
Property, or the receipt of proceeds therefrom, to the extent attributable to
production from the Conoco Property before the Effective Time. Michael shall
bear and pay all such taxes on production from the Conoco Property on and after
the Effective Time. Conoco shall withhold and pay on behalf of Michael all such
taxes on production from the Conoco Property between the Effective Time and the
Closing Date, and the amount of any such payment shall be reimbursed to Conoco
as a closing adjustment to the Purchase Price pursuant to Section 17. If either
Party pays taxes owed by the other Party, upon receipt of evidence of payment
the non-paying Party will reimburse the paying Party promptly for its
proportionate share of such taxes.

     (d) Tax and Financial Reporting.

         (i) IRS Form 8594. If the parties mutually agree that a filing of Form
8594 is required, the parties will confer and cooperate in the preparation and
filing of their respective forms to reflect a consistent reporting of the agreed
upon allocation of the value of the Conoco Property.

         (ii) Financial Reporting. Conoco and Michael agree to furnish to each
other at Closing or as soon thereafter as practicable any and all information
and documents reasonably required to comply with tax and financial reporting
requirements and audits.

         (iii) Intangible Drilling Cost Recapture. Conoco and Michael agree to
furnish to each other, at Closing or as soon as practicable thereafter, data
relative to deductions claimed, pursuant to Section 263(c) of the Internal
Revenue Code of 1986, for intangible drilling costs related to the Conoco
Property, and any other relevant data to allow each Party to calculate the
carryover intangible drilling costs associated with the Conoco Property that is
subject to potential recapture under Section 1254(a) of the Internal Revenue
Code of 1986.

<PAGE>   20

     (e) Sales and Use Taxes. The Purchase Price excludes any sales taxes or
other taxes in connection with the sale of the Conoco Property. Michael shall be
responsible for and pay all federal, state, or local sales, transfer, gross
proceeds, use and similar taxes incident or applicable to or caused by the
transfer of the Conoco Property to Michael under this Agreement. If Conoco is
required to pay such sales, use or similar taxes on behalf of Michael, Michael
will reimburse Conoco at Closing for all sales and use taxes due and payable on
the transfer of the Conoco Property to Michael.

     (f) Income Taxes. Each Party shall be responsible for its own state and
federal income taxes, if any, as may result from this transaction.

     (g) Incidental Expenses. Each party shall bear its own respective expenses
incurred in connection with the negotiation and Closing of this transaction,
including its own consultants' fees, attorneys' fees, accountants' fees, and
other similar costs and expenses.

  20. CASUALTY LOSS ON CONOCO PROPERTY. If prior to the Closing all or any
portion of the Conoco Property is substantially damaged or destroyed by fire or
other casualty ("Casualty Defect"), Conoco shall notify Michael promptly after
Conoco learns of such event. Conoco shall have the right, but not the
obligation, to cure the Casualty Defect by repairing such damage or, in the case
of personal property or fixtures, replacing them with equivalent items, no later
than Closing, all to Michael's reasonable satisfaction. If any uncured Casualty
Defect exists at the Closing, the Purchase Price shall be reduced by the
aggregate reduction in the value of the Conoco Property on account of such
uncured Casualty Defect as determined by the mutual agreement of the Parties. If
(i) the Parties fail for any reason to agree prior to the Closing as to the
amount of any Purchase Price adjustment on account of any uncured Casualty
Defects, or (ii) the amount of such downward adjustment of the Purchase Price at
Closing exceeds twenty percent (20%) of the Purchase Price, then either Party
upon written notice to the other Party shall have the right to terminate this
Agreement, in which event this Agreement shall be of no further force and effect
and neither Party shall have any further liability or obligation to the other
Party under this Agreement.

     (b) Acknowledgments of Michael at Closing. By closing on the transaction
provided for in this Agreement, Michael shall be deemed to have acknowledged and
does hereby acknowledge and admit that: (i) Michael has been given the
opportunity to adequately inspect the Conoco Property for all purposes prior to
Closing; (ii) Michael is aware that the Conoco Property has been used for the
exploration, development, production, treating and transporting of oil, gas and
other hydrocarbon products and that physical changes may have occurred as a
result of such use and that Conoco has disclosed, and Michael is further aware,
that there exists the possibility that there could exist on the Conoco Property
as a result of such use or uses one or more detrimental environmental conditions
(including without limitation naturally occurring radioactive material or
"NORM"), or that there could have occurred from such use or uses one or more
releases of hazardous substances (as defined in CERCLA or RCRA) or releases of
chemical substances into, or other pollution or contamination of or into, the
ambient air, surface water, ground water, or land surface and subsurface strata
of any real property included in the Conoco Property and of contiguous, or a
series of contiguous, real properties not associated with the Conoco Property;
(iii) Michael has entered into this Agreement on the basis of its own
investigation of the physical condition of the Conoco Property and the land
related thereto (including the environmental condition of the Conoco Property);
and (iv) MICHAEL, WITH FULL KNOWLEDGE OF THE FOREGOING AFTER CONDUCTING THE
ABOVE DESCRIBED INVESTIGATION AND EVALUATION, IS ACQUIRING THE CONOCO PROPERTY
ON A "WHERE IS" AND "AS IS" BASIS; AND MICHAEL, BY ACQUIRING THE CONOCO PROPERTY
ON A "WHERE IS" AND "AS IS" BASIS WAIVES ANY CLAIMS OR OTHER RIGHTS OF
INDEMNIFICATION, CONTRIBUTION OR RECOURSE IT MAY HAVE AGAINST OR FROM CONOCO
WITH RESPECT TO THE CONDITION OF THE CONOCO PROPERTY, INCLUDING, WITHOUT
LIMITATION, THE ENVIRONMENTAL CONDITION OF THE CONOCO PROPERTY AND DAMAGE TO
NATURAL RESOURCES ASSOCIATED WITH THE CONOCO PROPERTY (INCLUDING ANY LIABILITY
UNDER CERCLA OR OTHER ENVIRONMENTAL LAWS), WHETHER CONTRACT, TORT OR STATUTORY
IN

NATURE, REGARDLESS OF THE NEGLIGENCE, FAULT OR STRICT (STATUTORY) LIABILITY OF
CONOCO.

  23. INDEPENDENT EVALUATION. Michael represents that it has made an
independent evaluation of the Conoco Property, and acknowledges that Conoco has
made no statements or representations concerning the present or future value of
the anticipated income, costs, or profits, if any, to be derived from such
property, the physical or environmental condition of such property, the quantity
and quality of any oil and gas or other minerals that may be produced from such
property, or any other matter with respect to such property and THAT CONOCO
NEITHER IMPLIEDLY NOR EXPRESSLY WARRANTS THE DESCRIPTION, TITLE, VALUE, QUALITY,
PHYSICAL CONDITION OF SUCH PROPERTY (INCLUDING, WITHOUT LIMITATION, THE
ENVIRONMENTAL CONDITION OF SUCH PROPERTY), MERCHANTABILITY, OR FITNESS FOR
PURPOSE OF ANY OF SUCH PROPERTIES OR THE WELLS, EQUIPMENT, PIPELINE FACILITIES,
OR OTHER PROPERTY LOCATED THEREON OR USED IN CONNECTION THEREWITH. Michael
further acknowledges that, in entering into this Agreement, they have relied
solely upon its independent examination of the Conoco Property and public
records relating to such property and its independent estimates, computations,
evaluations, reports and studies based thereon and has not relied on any
representation or statement made by Conoco. All information and data furnished
to Michael is believed by Conoco to be accurate and correct to the best of its
knowledge without investigation; however, CONOCO MAKES NO WARRANTY OR
REPRESENTATION AS TO THE ACCURACY, COMPLETENESS, MATERIALITY OR CORRECTNESS OF
ANY INFORMATION FURNISHED TO MICHAEL. ANY RELIANCE BY MICHAEL ON SUCH
INFORMATION IS AT MICHAEL'S SOLE RISK AND CONOCO SHALL HAVE NO LIABILITY
WHATSOEVER TO MICHAEL IN CONNECTION THEREWITH.

  24. ENVIRONMENTAL ASSESSMENT AND INDEMNIFICATION.

     (a) Definition of Adverse Environmental Condition. "Adverse Environmental
Conditions" shall mean any individual contamination or condition that would
require $50,000 or more of out-of-pocket costs and expenses to remedy and that
is in violation of the Environmental Laws (as hereafter defined), resulting from
any discharge, release, disposal, production, storage, treatment, or any other
activities on, in or from the Conoco Property, or the migration or
transportation from other lands to the Conoco Property, prior to the Closing
Date, of any wastes, pollutants, contaminants, hazardous materials or other
materials or substances that are subject to regulation under any laws, rules or
regulations relating to the protection of health or the environment, including,
without limitation, the Clean Air Act, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, the Federal Water Pollution Control Act,
the Safe Drinking Water Act, the Toxic Substance Control Act, the Hazardous and
Solid Waste Amendments Act of 1984, the Superfund Amendments and Reauthorization
Act of 1986, the Hazardous Materials Transportation Act, the Clean Water Act,
the National Environmental Policy Act, the Endangered Species Act, the Fish and
Wildlife Coordination Act, the National Historic Preservation Act and the Oil
Pollution Act of 1990, as well as any state and local regulation or law
governing the same, similar or related matters, all as may have been or be
amended from time to time (collectively, "Environmental Laws"). The term
"Adverse Environmental Conditions" also shall include any such individual
contamination



                                      -17-
<PAGE>   23

or condition Of the Conoco Property that would require $50,000 or more of
out-of-pocket costs and expenses to remedy that is only temporarily authorized
by law, permit, fee agreement or other arrangement.

     (b) Pre-Closing Remedies. Michael shall promptly notify Conoco in writing
of any Adverse Environmental Condition that becomes known to Michael prior to
Closing as a result of Michael's investigation of the Conoco Property and the
estimated costs for remediating any such conditions which are located on the
Conoco Property. Michael will be deemed to have waived any claim against Conoco
with respect to any Adverse Environmental Condition known to Michael prior to
Closing and about which Michael fails to notify Conoco in writing prior to
Closing. Michael shall provide such information regarding any such Adverse
Environmental Conditions as Conoco may reasonably request. If Conoco receives
notice from Michael prior to Closing of any Adverse Environmental Condition,
Michael shall have the right to request a reduction in the Purchase Price equal
to the cost and expense of remediating the Adverse Environmental Condition to
Michael's reasonable satisfaction, the amount of which shall be mutually agreed
to by Conoco and Michael. If Conoco and Michael agree on the amount of a
Purchase Price reduction for an Adverse Environmental Condition, such reduction
shall be made at Closing. Any Adverse Environmental Condition for which Michael
receives a Purchase Price reduction shall become an Assumed Obligation of
Michael at Closing and Conoco shall have no further liability or obligation in
connection with such Adverse Environmental Condition. However, if (i) the
Parties are unable to agree on a Purchase Price reduction for any such Adverse
Environmental Condition, or (ii) the agreed cost of remedying all such Adverse
Environmental Conditions exceeds 3% of the Purchase Price, either Conoco or
Michael shall have the right to terminate this Agreement, in which event this
Agreement shall be of no further force and effect and neither Party shall have
any further liability or obligation to the other Party under this Agreement.

     (c) Post-Closing Remedies. If Michael notifies Conoco after Closing but on
or before one hundred and eighty (180) days following the Closing Date regarding
any Adverse Environmental Condition that became known to Michael after Closing,
Conoco shall reimburse Michael for all costs and expenses incurred by Michael in
remediating Such Adverse Environmental Condition, the amount of which shall be
mutually agreed to by Conoco and Michael. Upon receiving the agreed payment from
Conoco in connection with any such Adverse Environmental Condition, such Adverse
Environmental Condition shall become an Assumed Obligation of Michael and Conoco
shall have no further liability or obligation to Michael in connection with such
Adverse Environmental Condition. If Conoco and Michael are unable to agree on
the extent of any such Adverse Environmental Condition or on the remediation
costs associated with any such Adverse Environmental Condition, then the extent
of such Adverse Environmental Condition (if disputed) and/or the remediation
costs and expenses for which Conoco shall be responsible shall be determined by
binding arbitration in accordance with Section 30 of this Agreement. Conoco
shall have no liability or obligation to Michael under this Agreement (i) for
any Adverse Environmental Condition regarding which Conoco does not receive
timely written notice on or before one hundred and eighty (180) days following
the Closing Date (and all such Adverse Environmental Conditions shall become
Assumed Obligations of Michael), or (ii) for any costs and expenses of
remediating Adverse



                                      -18-
<PAGE>   24

Environmental Conditions of which Conoco has been properly notified pursuant to
this Section 24(c) in excess of $1,000,000.

     (d) Indemnity. Except for any costs or expenses for which Michael is
entitled to a Purchase Price reduction under Sections 24(b) or for which Michael
is entitled to reimbursement under Section 24(c), if the Closing hereunder
occurs, Michael shall indemnify, defend and hold Conoco harmless from and
against any and all Claims arising out of or relating to any discharge, release,
disposal, production, storage, treatment or any other activities on, in or from
the Conoco Property, or the migration or transportation from any other lands to
the Conoco Property, whether before or after the Effective Time, of any wastes,
pollutants, contaminants, hazardous materials, or materials or substances that
are presently, or become in the future, subject to regulation under
Environmental Laws, whether such Environmental Laws are presently existing or
are hereafter enacted, INCLUDING, WITHOUT LIMITATION, ANY SUCH CLAIMS ARISING IN
WHOLE OR IN PART FROM THE SOLE OR CONCURRENT NEGLIGENCE OR GROSS NEGLIGENCE OR
STRICT LIABILITY OF CONOCO. The foregoing indemnity shall not be applicable to
Claims arising out of or relating to activities on the South Callaghan Ranch
Lands after the date such lands have reverted back to Conoco pursuant to the
South Callaghan Ranch Lease.

     (e) Exclusive Remedy. The remedies set forth in this Section 24 are the
exclusive remedies between the Parties with respect to the environmental
condition of the Conoco Property, and Conoco will have no liability or
obligation to Michael with respect to the environmental condition of the Conoco
Property except as set forth in this Section 24.

     (f) Proportionate Reduction. If Conoco is the owner of less than 100% of
the mineral interest or working interest in any portion of the Conoco Property
that may be subject to an Adverse Environmental Condition for which a Purchase
Price reduction or cost and expense reimbursement is due under this Agreement,
the Parties shall proportionately reduce the amount due under this Agreement in
connection with any such Adverse Environmental Condition to reflect Conoco's
proportionate ownership interest in the affected property.

  25. WAIVER OF CONSEQUENTIAL AND PUNITIVE DAMAGES. NEITHER MICHAEL NOR
CONOCO SHALL BE ENTITLED TO RECOVER FROM THE OTHER, RESPECTIVELY, AND EACH PARTY
RELEASES THE OTHER PARTY FROM, ANY LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING
UNDER THIS AGREEMENT OR IN CONNECTION WITH OR WITH RESPECT TO THE TRANSACTIONS
CONTEMPLATED IN THIS AGREEMENT ANY AMOUNT IN EXCESS OF THE ACTUAL COMPENSATORY
DAMAGES SUFFERED BY SUCH PARTY. MICHAEL AND CONOCO BOTH WAIVE, AND RELEASE THE
OTHER FROM ANY RIGHT TO RECOVER PUNITIVE, SPECIAL, EXEMPLARY AND CONSEQUENTIAL
DAMAGES ARISING IN CONNECTION WITH OR WITH RESPECT TO THE TRANSACTIONS
CONTEMPLATED IN THIS AGREEMENT; PROVIDED, HOWEVER, ANY SUCH DAMAGES RECOVERED BY
A THIRD PARTY (OTHER THAN SUBSIDIARIES, AFFILIATES OR PARENTS OR A PARTY) FOR
WHICH A PARTY OWES THE OTHER PARTY AN INDEMNITY UNDER THIS AGREEMENT SHALL NOT
BE WAIVED.



                                      -19-
<PAGE>   25

  26. PRESS RELEASE. There shall be no press release or public communication
concerning this purchase and sale by either Party except with the written
consent of the Party not originating said release or communication, with the
exception being those reports reasonably required by applicable state or federal
law or regulations.

  27. SURVIVAL. The representations, warranties and agreements contained in
this Agreement and in any certificate or other instrument delivered by or on
behalf of either Party pursuant to this Agreement shall survive the Closing and
shall be unaffected by any investigation made by the other Party. All
representations and warranties contained in this Agreement (including without
limitation those in Sections 8 and 9) are exclusive, and are given in lieu of
all other representations and warranties, express, implied, or statutory.

  28. INTERPRETATION. The Parties stipulate and agree that this Agreement
shall be deemed and considered for all purposes to have been jointly prepared by
the Parties, and shall not be construed against any one Party (nor shall any
inference or presumption be made) on the basis of who drafted this Agreement or
any particular provision hereof, who supplied the form of Agreement, or any
other event of the negotiation, drafting or execution of this Agreement. Each
Party agrees that this Agreement has been purposefully drawn and correctly
reflects its understanding of the transaction that it contemplates. In
construing this Agreement, the following principles will apply.

     (a) Examples shall not be construed to limit, expressly or by implication,
the matter they illustrate.

     (b) The word "includes" and its derivatives means "includes, but is not
limited to" and corresponding derivative expressions.

     (c) Defined terms in this Agreement are denoted by quotation marks and
underlining. A defined term has its defined meaning throughout this Agreement
and each Appendix, Exhibit and Schedule to this Agreement, regardless of whether
it appears before or after the place where it is defined.

     (d) If there is any conflict or inconsistency between the provisions of the
main body of this Agreement and the provisions of any Appendix, Exhibit,
Schedule or executed conveyance document, the provisions of this Agreement shall
take precedence. If there is any conflict between the provisions of any pro
forma conveyance document or other transaction documents attached to this
Agreement as an Appendix, Exhibit or Schedule and the provisions of any
conveyance documents and other transaction documents actually executed by the
parties, the provisions of the executed conveyance documents and other executed
transaction documents shall take precedence.

     (e) The omission of certain provisions of this Agreement from the
conveyance documents does not constitute a conflict or inconsistency between
this Agreement and the conveyance documents, and will not effect a merger of the
omitted provisions. To the fullest



                                      -20-
<PAGE>   26

extent permitted by law, all provisions of this Agreement are hereby deemed

significance in interpreting or otherwise affect the meaning of this Agreement.

  29. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES HERETO SHALL BE GOVERNED, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF TEXAS, EXCLUDING ANY CONFLICTS-OF-LAW RULE THAT MIGHT
APPLY THE LAW OF ANOTHER JURISDICTION. TO THE EXTENT APPLICABLE, THE PARTIES
WAIVE THE PROVISIONS OF THE "TEXAS DECEPTIVE PRACTICES ACT," OTHER THAN SECTION
17.555 THEREOF WHICH MAY NOT BE WAIVED.                                

  30. DISPUTE RESOLUTION.

     (a) CONOCO AND MICHAEL SHALL ATTEMPT IN GOOD FAITH TO RESOLVE ANY
CONTROVERSY OR DISPUTE ARISING OUT OF OR RELATING TO THIS AGREEMENT PROMPTLY BY
NEGOTIATIONS BETWEEN THEMSELVES. THE NEGOTIATION PROCESS MAY BE STARTED BY THE
GIVING OF WRITTEN NOTICE BY EITHER PARTY TO THE OTHER PARTY IN ACCORDANCE WITH
THE TERMS OF SECTION 21 HEREOF. IN THE EVENT THAT EITHER PARTY DESIRES THE
INVOLVEMENT OF A MEDIATOR TO FACILITATE THE NEGOTIATIONS, THEN IT SHALL GIVE
WRITTEN NOTICE THEREOF, AND THE PARTIES AGREE, ADDITIONALLY, TO NEGOTIATE IN
GOOD FAITH TO SELECT AN INDEPENDENT MEDIATOR TO FACILITATE THE NEGOTIATIONS AND
TO CONDUCT UP TO EIGHT CONSECUTIVE HOURS OF NON-BINDING MEDIATED NEGOTIATIONS IN
HOUSTON, TEXAS WITHIN 30 DAYS AFTER THE NOTICE REQUESTING INVOLVEMENT OF A
MEDIATOR IS FIRST SENT. IF, WITHIN 10 DAYS AFTER THE NOTICE REQUESTING A
MEDIATOR, THE PARTIES ARE NOT ABLE TO AGREE UPON A MEDIATOR, THEN EITHER PARTY
MAY SEEK THE APPOINTMENT OF A MEDIATOR UNDER SUB-PARAGRAPH 30(D).

     (b) NO ARBITRATION MAY BE COMMENCED BY EITHER PARTY UNLESS AND UNTIL A GOOD
FAITH EFFORT HAS BEEN MADE TO CONDUCT NEGOTIATIONS AND, IF REQUESTED BY A PARTY,
A MEDIATION IN COMPLIANCE WITH THE FOREGOING PARAGRAPH. IF A CONTROVERSY OR
DISPUTE IS NOT RESOLVED AFTER GOOD FAITH EFFORTS TO CONDUCT THE NEGOTIATION AND
MEDIATION PROCESS DESCRIBED ABOVE, THEN, UPON NOTICE BY EITHER PARTY TO THE
OTHER PARTY (AN "ARBITRATION NOTICE"), THE CONTROVERSY OR DISPUTE SHALL BE
SUBMITTED TO FINAL, BINDING ARBITRATION UNDER THE FOLLOWING PROVISIONS.

     (c) AN ARBITRATION NOTICE SHALL DESCRIBE THE CONTROVERSY OR DISPUTE TO BE
SUBMITTED TO ARBITRATION AND SHALL NAME ONE ARBITRATOR. WITHIN THIRTY (30) DAYS
AFTER THE RECEIPT OF SUCH NOTICE, THE OTHER PARTY SHALL BY WRITTEN RESPONSE
DESCRIBE ANY ADDITIONAL CONTROVERSY OR DISPUTE TO BE SUBMITTED AND SHALL NAME A
SECOND ARBITRATOR. IF SUCH PARTY FAILS TO TIMELY NAME A SECOND ARBITRATOR, THE
PARTY FIRST GIVING THE ARBITRATION NOTICE MAY BY FURTHER WRITTEN NOTICE NAME THE
SECOND. THE TWO ARBITRATORS SO APPOINTED SHALL NAME



                                      -21-
<PAGE>   27

A THIRD ARBITRATOR, WHO SHALL BE INDEPENDENT AND IMPARTIAL AND WHO, LIKE THE
TWO ARBITRATORS SO APPOINTED, SHALL BE QUALIFIED, BY KNOWLEDGE AND EXPERIENCE
(WITH EACH HAVING A MINIMUM OF 10 YEARS OIL AND GAS EXPERIENCE), TO DETERMINE
THE CONTROVERSY OR DISPUTE SUBMITTED. IF THE TWO APPOINTED ARBITRATORS FAIL TO
TIMELY NAME A THIRD ARBITRATOR, THEN EITHER PARTY MAY SEEK THE APPOINTMENT OF A
THIRD UNDER SUB-PARAGRAPH 30(D).

     (d) IF THE PARTIES ARE UNABLE TO AGREE UPON A MEDIATOR OR THE PARTIES'
APPOINTED ARBITRATORS ARE UNABLE TO SELECT A THIRD ARBITRATOR, THEN EITHER PARTY
MAY SEEK THE APPOINTMENT OF A MEDIATOR OR A THIRD ARBITRATOR AS FOLLOWS. EITHER
PARTY MAY REQUEST THE JUDGE OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF TEXAS, HOUSTON DIVISION, HAVING GREATEST TENURE BUT NOT ON SENIOR
STATUS TO APPOINT A MEDIATOR OR THIRD ARBITRATOR, WHO SHALL BE INDEPENDENT AND
IMPARTIAL AND QUALIFIED TO DETERMINE THE MATTERS SUBMITTED IN THAT JUDGE'S SOLE
OPINION. IF THAT JUDGE FAILS, WITHIN THIRTY (30) DAYS OF SUBMISSION OF THE
REQUEST, TO APPOINT A MEDIATOR OR THIRD ARBITRATOR, THEN EITHER PARTY MAY MAKE
THE SAME REQUEST TO THE JUDGE OF THAT COURT WITH THE NEXT GREATEST TENURE, AND
SO ON, UNTIL THE MEDIATOR IS APPOINTED AND THE PANEL OF ARBITRATORS IS
CONSTITUTED. IF, PRIOR TO RENDERING A DECISION, AN ARBITRATOR RESIGNS OR BECOMES
UNABLE TO SERVE, HE SHALL BE REPLACED AS FOLLOWS. IF HE WAS ONE OF THE TWO
ARBITRATORS APPOINTED BY THE PARTIES, THE PARTY THAT NAMED HIM SHALL NAME HIS
REPLACEMENT; PROVIDED, HOWEVER, THAT IF HIS REPLACEMENT IS NOT NAMED WITHIN
FIFTEEN (15) DAYS, THE OTHER PARTY SHALL NAME HIS REPLACEMENT. IF HE WAS THE
THIRD ARBITRATOR SELECTED BY THE TWO ARBITRATORS NAMED BY THE PARTIES, THOSE TWO
ARBITRATORS SHALL NAME HIS REPLACEMENT; PROVIDED, HOWEVER, THAT IF THEY FALL TO
AGREE ON HIS REPLACEMENT WITHIN FIFTEEN (15) DAYS, EITHER PARTY MAY FOLLOW THE
PROCEDURE SPECIFIED IN THIS SUBPARAGRAPH (d).

     (e) THE ARBITRATION SHALL OCCUR IN HOUSTON, TEXAS AND SHALL BE CONDUCTED IN
ACCORDANCE WITH THE AMERICAN ARBITRATION ASSOCIATION'S COMMERCIAL ARBITRATION
RULES IN EFFECT AT THE TIME OF THE ARBITRATION NOTICE (THE "RULES"). THE PARTIES
AGREE THAT THEY WILL FAITHFULLY OBSERVE THIS AGREEMENT AND THE RULES AND THAT
THEY WILL ABIDE BY AND PERFORM ANY FINAL AWARD RENDERED BY THE ARBITRATORS.
ADDITIONALLY, THE ARBITRATION SHALL BE CONDUCTED IN A MANNER CONSISTENT WITH THE
FEDERAL ARBITRATION ACT, 9 U.S.C. SECTIONS 1 ET SEQ. (THE "FAA") OR CONSISTENT
WITH THE SAME PRINCIPLES ENUNCIATED IN THE FAA IN THE EVENT IT MAY NOT BE
TECHNICALLY APPLICABLE; PROVIDED, HOWEVER, THAT RULES ESTABLISHED UNDER THE FAA
THAT THE PARTIES CANNOT ELECT AS APPLICABLE IF THE FAA IS NOT TECHNICALLY
APPLICABLE, SUCH AS PROCEDURAL RULES CONCERNING ENFORCEMENT OF AWARDS, ACCESS TO
THE COURTS, PROCEDURES FOR REVIEW, AND MATTERS CONCERNING SUBJECT MATTER
JURISDICTION, SHALL NOT BE BINDING IF THE FAA IS NOT TECHNICALLY APPLICABLE. THE
CONTROVERSY OR DISPUTE SUBMITTED SHALL BE RESOLVED BY THE DECISION OF A MAJORITY
OF THE PANEL OF ARBITRATORS. THE AWARD OR JUDGMENT OF THE PANEL SHALL BE FINAL
AND BINDING ON THE PARTIES AND JUDGMENT UPON THE AWARD OR JUDGMENT OF THE PANEL
MAY BE ENTERED AND ENFORCED IN ANY COURT HAVING JURISDICTION. NO LITIGATION OR
OTHER JUDICIAL PROCEEDING MAY EVER BE INITIATED AT ANY TIME IN ANY COURT FOR THE
PURPOSE OF ADJUDICATING, INTERPRETING, OR ENFORCING THE RIGHTS OR OBLIGATIONS OF
THE PARTIES TO THIS AGREEMENT, OR TO DETERMINE THE VALIDITY OF OR ADJUDICATE A
CLAIM OF BREACH OF THIS AGREEMENT; PROVIDED, HOWEVER, THAT THIS PROHIBITION
SHALL NOT APPLY TO LITIGATION OR OTHER JUDICIAL PROCEEDINGS UNDERTAKEN TO SEEK
ENFORCEMENT OF THE PARTIES' AGREEMENT TO ARBITRATE


                                      -22-
<PAGE>   28

OR TO ENFORCE ANY ARBITRATION AWARD OR SEEK REVIEW OR ANY ARBITRATION AWARD.
REVIEW OF SUCH ARBITRATION AWARD SHALL BE PERMITTED ONLY ON GROUNDS THAT (i)
THE AWARD WAS PROCURED BY CORRUPTION, FRAUD, OR UNDUE MEANS; (ii) THERE WAS
EVIDENT PARTIALITY OR CORRUPTION IN THE THIRD APPOINTED ARBITRATOR; (iii) THE
PANEL WAS GUILTY OF MISCONDUCT IN REFUSING TO HEAR EVIDENCE PERTINENT AND
MATERIAL TO THE CONTROVERSY; (iv) THE PANEL EXCEEDED THEIR POWERS; OR (v) THERE
WAS NO AGREEMENT TO ARBITRATE THE MATTER SUBMITTED AND RULED UPON AND THE PARTY
AFFECTED DID NOT PARTICIPATE IN THE ARBITRATION HEARING WITHOUT RAISING THE
OBJECTION. THE PARTIES EXPRESSLY AGREE THAT AN AWARD SHALL IN NO OTHER RESPECT
BE APPEALABLE OR SUBJECT TO REVIEW. IF EITHER PARTY BECOMES THE SUBJECT OF A
BANKRUPTCY, RECEIVERSHIP OR OTHER SIMILAR PROCEEDING UNDER THE LAWS OF THE
UNITED STATES OF AMERICA, ANY STATE OR COMMONWEALTH OR ANY OTHER NATION OR
POLITICAL SUBDIVISION THEREOF, THEN, TO THE EXTENT PERMITTED OR NOT PROHIBITED
BY APPLICABLE LAW, ANY FACTUAL OR SUBSTANTIVE LEGAL ISSUES ARISING IN OR DURING
THE PENDENCY OF ANY SUCH PROCEEDING SHALL BE SUBJECT TO ALL OF THE FOREGOING
MEDIATION AND ARBITRATION PROVISIONS AND SHALL BE RESOLVED, TO THE EXTENT
PERMITTED, IN ACCORDANCE THEREWITH. THE AGREEMENTS CONTAINED HEREIN HAVE BEEN
GIVEN FOR VALUABLE CONSIDERATION, ARE COUPLED WITH AN INTEREST AND ARE NOT
INTENDED TO BE EXECUTORY CONTRACTS. THE FEES AND EXPENSES OF THE MEDIATOR WILL
BE SHARED EQUALLY BY THE PARTIES AND THE FEES AND EXPENSES OF THE THIRD
ARBITRATOR WILL BE SHARED BY THE PARTIES ON A BASIS DETERMINED TO BE FAIR AND
EQUITABLE BY THE PANEL, TAKING INTO ACCOUNT THE RELATIVE FAULT OF EACH PARTY,
THE RELATIVE CREDIBILITY AND MERIT OF ALL CLAIMS AND DEFENSES MADE BY EACH
PARTY AND THE COOPERATION, SPEED AND EFFICIENCY OF EACH PARTY IN CONDUCTING THE
ARBITRATION PROCEEDINGS AND COMPLYING WITH THE RULES AND WITH THE ORDERS AND
REQUESTS OF THE PANEL.

     (f) WITHIN 10 DAYS AFTER THE SELECTION OF THE THIRD ARBITRATOR, THE PARTIES
AND THEIR COUNSEL WILL APPEAR BEFORE THE PANEL AT A PLACE AND TIME IN HOUSTON,
TEXAS AS MAY BE DESIGNATED BY THE PANEL FOR THE PURPOSE OF EACH PARTY MAKING A
ONE HOUR OR LESS PRESENTATION AND SUMMARY OF THE CASE. THEREAFTER, THE PANEL
WILL SET DATES AND TIMES FOR ADDITIONAL HEARINGS UNTIL THE PROCEEDING IS
CONCLUDED. THE DESIRE AND GOAL OF THE PARTIES IS, AND THE PANEL WILL BE ADVISED
THAT THEIR GOAL SHOULD BE, TO CONDUCT AND CONCLUDE THE ARBITRATION PROCEEDING AS
EXPEDITIOUSLY AS POSSIBLE. IF ANY PARTY OR HIS COUNSEL FAILS, WITHOUT GOOD
CAUSE, TO APPEAR AT ANY HEARING, THE PANEL SHALL BE ENTITLED TO REACH A DECISION
BASED ON THE EVIDENCE WHICH HAS BEEN PRESENTED TO HIM BY THE OTHER PARTY WHO DID
APPEAR.

     (g) ANY ARBITRAL AWARD MAY BE ENFORCED IN THE COURTS OF THE STATE OF TEXAS
OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS AND, BY
EXECUTION AND DELIVERY OF THIS AGREEMENT, THE PARTIES HEREBY ACCEPT FOR
THEMSELVES AND IN RESPECT OF THEIR PROPERTY, GENERALLY AND UNCONDITIONALLY, THE
NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS FOR SAID PURPOSE AND THE
PARTIES HEREBY IRREVOCABLY WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW ANY
OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE
OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH THEY MAY NOW OR HEREAFTER
HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE
JURISDICTIONS.


                                      -23-

supersede any prior agreement between the parties, whether written or oral,
relating to the subject hereof. This Agreement may be supplemented, altered,
amended, modified or revoked by writing only, signed by both Parties.

  32. BINDING EFFECT; ASSIGNMENT. This Agreement shall be binding upon and
inure to the benefit of the Parties and their respective successors and assigns.

convenience.

  33. COMPLIANCE AND ENFORCEMENT WAIVERS. Any of the terms, provisions,
covenants, representations, warranties or conditions hereof may be waived only
by a written instrument executed by the Party waiving compliance. Except as
otherwise expressly provided in this Agreement, the failure of any Party at any
time or times to require performance of any provision hereof shall in no manner
affect such Party's right to enforce the same. No waiver by any Party of any
condition, or of the breach of any term, provision, covenant, representation or
warranty contained in this Agreement, whether by conduct or otherwise, in any
one or more instances, shall be deemed to be or construed as a further or
continuing waiver of any such condition or breach or a waiver of any other
condition or of the breach of any other term, provision, covenant,
representation or warranty.

  34. THIRD-PARTY BENEFICIARIES. It is understood and agreed that there shall
be no third-party beneficiary of this Agreement, and that the provisions hereof

Agreement shall continue and remain in full force and effect.

  37. COUNTERPARTS. This Agreement may be executed in counterparts, each of
which shall constitute an original and all of which shall constitute one
document.

     5. TITLE DEFECTS ON EOG PROPERTY. As used in this Agreement, the term "EOG
Title Defect" shall mean a material deficiency in one (or more) of the following
respects:

         (a) EOG's title, as of the Effective Time (as defined hereinafter), as
to all or any portion of the EOG Property, is subject to an outstanding
mortgage, deed of trust, lien or encumbrance or other adverse claim which would
interfere materially with the ownership, operation, use or value of the EOG
Property;

         (b) EOG owns less than the net revenue interest described on Exhibit
"A-1" or more than the working interest described on Exhibit "A-1" without a
corresponding increase in net revenue interest;

         (c) EOG's rights and interests are subject to being reduced by virtue
of the exercise by a third party of any preferential right, reversionary,
back-in or other similar right not reflected on Exhibit "A-1;" and

         (d) EOG is in default under some material provision of a lease, farmout
agreement, operating agreement, or other agreement affecting the EOG Property.

         Michael shall give EOG written notice of each EOG Title Defect on or

<PAGE>   5


BASED UPON A BREACH OF THE LIMITED WARRANTY OF TITLE PROVIDED IN THE ASSIGNMENT
AND BILL OF SALE ATTACHED HERETO AS EXHIBIT "F."

     6. PURCHASE PRICE ADJUSTMENTS ON EOG PROPERTY.

        Michael may, by delivery of written notice to EOG of the existence of an
EOG Title Defect, request a reduction of the Purchase Price. Conversely, EOG
may, by delivery of written notice to Michael, request an increase in the
Purchase Price because the net revenue interest owned by EOG in the EOG Property
is greater than that shown on Exhibit "A-1."

        Any such notice by Michael or EOG shall include appropriate evidence to
substantiate its position and shall be delivered to the other Party on or before
five (5) days prior to the Closing. In the event any such notice is not timely
delivered, Michael shall thereafter have no right to assert an EOG Title Defect
and EOG shall thereafter have no right to assert a larger net revenue interest.

        Upon timely delivery of a notice either by Michael of an EOG Title
Defect or by EOG of a larger net revenue interest, Michael and EOG shall meet,
within the period between the date of receipt of such notice and the Closing
Date, and may mutually agree as follows with respect to any EOG Title Defect:
(i) EOG shall cure or agree to cure such EOG Title Defect, to a degree agreed
upon prior to Closing (provided, however, EOG shall have no obligation to
perform such cure), (ii) Michael shall agree to accept the interest "AS IS," and
release EOG from all claims related thereto, (iii) EOG shall agree to indemnify
Michael against all losses, costs, expenses and liabilities with respect to such
EOG Title Defect, or (iv) EOG and Michael shall agree as to the amount of a
Purchase Price adjustment in connection with such EOG Title Defect. If no
agreement can otherwise be reached as to the disposition of an interest burdened
by an EOG Title Defect or with respect to EOG's larger net revenue interest
prior to the Closing Date, either Party may give written notice to the other
Party on or before the Closing Date to terminate this Agreement and upon the
giving of such notice, this Agreement shall be of no further force and effect.






                                       5
<PAGE>   6


        In the event the net amount of the Purchase Price adjustments hereunder
exceeds ten percent (10%) of the Purchase Price, then either Michael or EOG
may, upon written notice to the other Party, cancel this Agreement and the same
shall be of no further force and effect.

        If Michael receives a Purchase Price adjustment at Closing on account of
an EOG Title Defect, EOG shall have until June 30, 1998 to cure such EOG Title
Defect at its cost. If by such date it can demonstrate to Michael's reasonable
satisfaction that such EOG Title Defect has been cured, then EOG shall be
entitled to reimbursement from Michael for the amount of such Purchase Price
adjustment. Michael shall pay such amount to EOG within fifteen (15) business
days of the date EOG demonstrates to Michael's reasonable satisfaction that such
EOG Title Defect has been cured.

     7. TITLE DEFECTS ON MICHAEL PROPERTY. As used in this Agreement, the term
"MICHAEL Title Defect" shall mean a material deficiency in one (or more) of the
following respects:

        (a) Michael's title, as of the Effective Time, as to all or any portion
of the MICHAEL Property, is subject to an outstanding mortgage, deed or trust,
lien or encumbrance or other adverse claim which would interfere materially with
the ownership, operation, use or value of the MICHAEL Property;

        (b) Michael owns less than the net revenue interest described on Exhibit
"D" or more than the working interest described on Exhibit "D" without a
corresponding increase in net revenue interest;

        (c) Michael's rights and interests are subject to being reduced by
virtue of the exercise by a third party of any preferential right, reversionary,
back-in or other similar right not reflected on Exhibit "D;" and

        (d) Michael is in default under some material provision of a lease,
farmout agreement or agreement affecting the MICHAEL Property.

        EOG shall give Michael written notice of each MICHAEL Title Defect on or
before five (5) days prior to the Closing Date, together with full particulars
relating thereto. EOG








                                       6
<PAGE>   7

SHALL BE DEEMED TO HAVE WAIVED ALL MICHAEL TITLE DEFECTS OF WHICH MICHAEL HAS
NOT BEEN GIVEN TIMELY WRITTEN NOTICE, SAVE AND EXCEPT CLAIM BASED UPON A BREACH
OF THE LIMITED WARRANTY OF TITLE PROVIDED IN THE ASSIGNMENT ATTACHED HERETO AS
EXHIBIT "I." EOG and Michael hereby agree that the allocated value of the
MICHAEL Property, for purposes of notice to preferential rights holders only, is
$1,500,000.00.

     8. PURCHASE PRICE ADJUSTMENTS ON MICHAEL PROPERTY. EOG may, by delivery of
written notice to Michael of the existence of a MICHAEL Title Defect, request an
increase in the Purchase Price.

        Any such notice by EOG shall include appropriate evidence to
substantiate its position and shall be delivered to Michael on or before five
(5) days prior to the Closing. In the event any such notice is not timely
delivered, EOG shall thereafter have no right to assert a MICHAEL Title Defect.

        Upon timely delivery of a notice by EOG of a MICHAEL Title Defect, EOG
and Michael shall meet, within the period between the date of receipt of such
notice and the Closing Date, and may mutually agree as follows: (i) Michael
shall cure or agree to cure such MICHAEL Title Defect, to a degree agreed upon
prior to Closing (provided, however, Michael shall have no obligation to perform
such cure), (ii) EOG shall agree to accept the interest "AS IS," and release
Michael from all claims related thereto, (iii) Michael shall agree to indemnify
EOG against all losses, costs, expenses and liabilities with respect to such
MICHAEL Title Defect, or (iv) Michael and EOG shall agree as to the amount of a
Purchase Price adjustment in connection with such MICHAEL Title Defect. If no
agreement can otherwise be reached as to the disposition of an interest burdened
by a MICHAEL Title Defect prior to the Closing Date, either Party may give
written notice to the other Party on or before the Closing Date to terminate
this Agreement and, upon the giving of such notice, this Agreement shall be of
no further force and effect.

        If EOG receives a Purchase Price adjustment at Closing on account of a
MICHAEL Title Defect, Michael shall have until June 30, 1998 to cure such
MICHAEL Title Defect at its



                                       7

<PAGE>   8


cost. If by such date it can demonstrate to EOG's reasonable satisfaction that
such MICHAEL Title Defect has been cured, then Michael shall be entitled to
reimbursement from EOG for the amount of such Purchase Price adjustment. EOG
shall pay such amount to Michael within fifteen (15) business days of the date
Michael demonstrates to EOG's reasonable satisfaction that such MICHAEL Title
Defect has been cured.

     9. GAS IMBALANCES FOR EOG PROPERTY. In the event it is determined that a
net gas imbalance exists with respect to operations relating to the EOG
Property, the Purchase Price shall be adjusted upward or downward, as the case
may be, to reflect the effect of such net gas imbalance for the EOG Property as
of the Effective Time. Such adjustment shall be calculated by multiplying the
per Mcf amount of the gas imbalance, as of the Effective Time, by $2.25 per Mcf.

     10. GAS IMBALANCES FOR MICHAEL PROPERTY. In the event it is determined that
a net gas imbalance exists with respect to operations relating to the MICHAEL
Property, the Purchase Price shall be adjusted upward or downward, as the case
may be, to reflect the effect of such net gas imbalance for the MICHAEL Property
as of the Effective Time. Such adjustment shall be calculated by multiplying the
per Mcf amount of the gas imbalance, as of the Effective Time, by $2.25 per Mcf.

     20. CLOSING ADJUSTMENTS ON MICHAEL PROPERTY. All Property Taxes
attributable to the MICHAEL Property for the year 1998 shall be paid by EOG. All

adjustment or payment that was not finally determined as of the Closing in
connection with the EOG Property and showing the calculation






                                       18
<PAGE>   19
of such adjustments to the Purchase Price. As soon as practicable after receipt
of the Intermediate Settlement Statement, Michael shall deliver to EOG a written
report containing any changes that Michael proposes be made to such Intermediate
Settlement Statement. The Parties undertake to agree with respect to such
Intermediate Settlement Statement no later than 60 days after the Closing Date;
such agreement constituting and to be embodied in a "Final Settlement Statement"
and to establish the "Final Purchase Price," and the date upon which the Final
Purchase Price is established to be the "Final Settlement Date." In the event
Michael and EOG are unable to mutually agree upon the amount of the Final
Settlement Statement in connection with the EOG Property, an audit shall be
conducted by a mutually agreed upon accounting firm. Michael and EOG agree to be
bound by the findings of such audit, insofar as the Final Settlement Statement
amount is concerned, and each shall bear one half of all expenses associated
with such audit. In the event that (a) the Final Purchase Price is more than the
amount paid at Closing, Michael shall pay to EOG the amount of such difference,
or (b) the Final Purchase Price is less than the amount paid at Closing, EOG
shall pay to Michael the amount of such difference, in either event by wire
transfer in immediately available funds, or, if the amount of such difference is
less than $25,000, by corporate check.

In connection with the EOG Property, EOG shall be responsible for the settlement
of all joint billing audits which relate to accounting periods prior to the

reimbursed to EOG by Michael.

     22. POST-CLOSING ACCOUNTING ON MICHAEL PROPERTY. As soon as practicable

accounting principles, the Intermediate Settlement Statement setting forth for
the MICHAEL Property each






                                       19
<PAGE>   20
adjustment or payment that was not finally determined as of the Closing in
connection with the MICHAEL Property and showing the calculation of such
adjustments to the Purchase Price. As soon as practicable after receipt of the
Intermediate Settlement Statement, Michael shall deliver to EOG a written report
containing any changes that Michael proposes be made to such Intermediate
Settlement Statement. The Parties undertake to agree with respect to such
Intermediate Settlement Statement no later thin 60 days after the Closing Date;
such agreement constituting and to be embodied in a "Final Settlement Statement"
and to establish the "Final Purchase Price," and the date upon which the Final
Purchase Price is established to be the "Final Settlement Date." In the event
EOG and Michael are unable to mutually agree upon the amount of the Final
Settlement Statement in connection with the MICHAEL Property, an audit shall be
conducted by a mutually agreed upon accounting firm. EOG and MICHAEL agree to be
bound by the findings of such audit, insofar as the Final Settlement Statement
amount is concerned, and each shall bear one half of all expenses associated
with such audit. In the event that (a) the Final Purchase Price is more than the
amount paid at Closing, EOG shall pay to Michael the amount of such difference,
or (b) the Final Purchase Price is less than the amount paid at Closing, Michael
shall pay to EOG the amount of such difference, in either event by wire
transfer in immediately available funds, or, if the amount of such difference is
less than $25,000, by corporate check.

settlement of all joint billing audits which relate to accounting periods prior

     23. TAXES ON EOG PROPERTY. The Purchase Price excludes any sales taxes or
other taxes in connection with the sale of the EOG Property because the parties
believe that this sale is exempt from sales tax. If a determination is ever made
that a sales tax or other transfer tax





                                       20
<PAGE>   21

applies, Michael shall be liable for such tax as well as any applicable
conveyance, transfer and recording fees, and real estate transfer stamps or
taxes imposed on any transfer of the EOG property pursuant to this Agreement.
Michael shall defend and hold EOG harmless with respect to the payment of all
such taxes, if any, including any interest or penalties assessed thereon.

All taxes (other than ad valorem and income taxes) which are imposed on or with
respect to the production of oil, natural gas or other hydrocarbons or minerals
from the EOG Property or the receipt of proceeds therefrom (including but not
limited to severance, production, excise and windfall profit taxes) shall be
apportioned between the Parties based upon the respective shares of production
taken by the Parties. Payment or withholding of all such taxes which have
accrued prior to the Effective Time and filing of all statements, returns and
documents pertinent thereto shall be the responsibility of EOG. Payment or
withholding of all such taxes which have accrued from and after the Effective
Time and the filing of all statements, returns and documents incident thereto
shall be the responsibility of Michael.

     24. TAXES ON MICHAEL PROPERTY. The Purchase Price excludes any sales taxes
or other taxes in connection with the sale of the MICHAEL Property because the
parties believe that this sale is exempt from sales tax. If a determination is
ever made that a sales tax or other transfer tax applies, EOG shall be liable
for such tax as well as any applicable conveyance, transfer and recording fees,
and real estate transfer stamps or taxes imposed on any transfer of the MICHAEL
Property pursuant to this Agreement. EOG shall defend and hold Michael harmless,
with respect to the payment of all such taxes, if any, including any interest or
penalties assessed thereon.

All taxes (other than ad valorem and income taxes) which are imposed on or with
respect to the production of oil, natural gas or other hydrocarbons or minerals
from the MICHAEL Property or the receipt of proceeds therefrom (including but
not limited to severance, production, excise and windfall profit taxes) shall be
apportioned between the Parties based upon the respective shares







                                       21
<PAGE>   22
of production taken by the Parties. Payment or withholding of all such taxes
which have accrued prior to the Effective Time and filing of all statements,
returns and documents pertinent thereto shall be the responsibility of Michael.
Payment or withholding of all such taxes which have accrued from and after the
Effective Time and the filing of all statements, returns and documents incident
thereto shall be the responsibility of EOG.

     25. FURTHER OPERATION OF EOG PROPERTY. EOG shall, as to the EOG Property it
now operates, continue to operate the same until the Closing, when such
operation shall be turned over to Michael: such operation from and after the
Effective Time shall be conducted by EOG for and on behalf of Michael; and for
any such services performed by EOG from and after the Effective Time, Michael
shall pay EOG for all reasonable and necessary expenses incurred by EOG in such
operation, protection or maintenance of the EOG Property, excluding overhead
charges as to the EOG Property operated by EOG. Such expenses may be recovered
by EOG as part of the closing, or post-closing adjustments, as appropriate.

In its operation of the EOG Property after full execution of this Agreement, EOG
shall continue to exercise the standard of care of an ordinary prudent operator
in the operation of the EOG Property and shall notify Michael of any material
adverse change in the productive capability of any well included in the EOG
Property.

     26. CASUALTY LOSS ON EOG PROPERTY. If prior to the Closing all or any
portion of the EOG Property is substantially damaged or destroyed by fire or
other casualty ("EOG Casualty Defect"), EOG shall notify Michael promptly after
EOG learns of such event. EOG shall have the right, but not the obligation, to
cure the EOG Casualty Defect by repairing such damage or, in the case of
personal property or fixtures, replacing them with equivalent items, no later
than Closing, all to Michael's reasonable satisfaction. If any uncured EOG
Casualty Defect exists at the Closing, the Purchase Price shall be reduced by
the aggregate reduction in the value of the EOG Property on account of such EOG
Casualty Defect as determined by the mutual





                                       22
<PAGE>   23
agreement of the Parties. If the Parties fail for any reason to agree prior to
the Closing as to the amount of any Purchase Price adjustment on account of EOG
Casualty Defects, either Party shall have the right to terminate this Agreement
and the same shall be of no further force and effect. In the event the amount of
such downward adjustment of the Purchase Price exceeds twenty percent (20%) of
the Purchase Price, then EOG or Michael may, upon written notice to the other
Party, cancel this Agreement and the same shall be of no further force and
effect.

     27. CASUALTY LOSS ON MICHAEL PROPERTY. If prior to the Closing all or any
portion of the MICHAEL Property is substantially damaged or destroyed by fire or
other casualty ("MICHAEL Casualty Defect"), Michael shall notify EOG promptly
after Michael learns of such event. MICHAEL shall have the right, but not the
obligation, to cure the MICHAEL Casualty Defect by repairing such damage or, in
the case of personal property or fixtures, replacing them with equivalent items,
no later than Closing, all, to EOG's reasonable satisfaction. If any uncured
MICHAEL Casualty Defect exists at the Closing, the Purchase Price shall be
increased by the aggregate reduction in the value of the MICHAEL Property on
account of such MICHAEL Casualty Defect as determined by the mutual agreement of
the Parties. If the Parties fail for any reason to agree prior to the Closing as
to the amount of any Purchase Price adjustment on account of MICHAEL Casualty
Defects, either Party shall have the right to terminate this Agreement and the
same shall be of no further force and effect.

     28. BROKER'S FEE. EOG represents and warrants to Michael that EOG has
incurred no liability, contingent or otherwise, for broker's or finder's fees in
respect of this Agreement or the transactions contemplated hereby for which
Michael shall have any responsibility whatsoever; and Michael represents and

for broker's or finder's fees in respect of this Agreement or the transactions

     33. ENVIRONMENTAL ASSESSMENT AND INDEMNIFICATION - EOG PROPERTY. (a) "EOG
Adverse Environmental Conditions" shall mean any individual contamination or
condition that would require $50,000 or more of out-of-pocket costs and expenses
to remedy and that is not otherwise permanently authorized by permit or law,
resulting from any discharge, release, disposal, production, storage, treatment,
or any other activities on, in or from the EOG Property, or the migration or
transportation from other lands to the EOG Property, prior to the Closing Date,
of any wastes, pollutants, contaminants, hazardous materials or other materials
or substances that are subject to regulation under any laws, rules or
regulations relating to the protection of health or the environment, including,

individual contamination or condition of the EOG Property that would require
$50,000 or more of out-of-pocket costs and expenses to remedy that is

Condition discovered after the date hereof as a result of its investigation of

regarding such EOG Adverse Environmental Conditions as EOG may reasonably
request. If EOG receives notice from Michael prior to Closing of any






                                       28
<PAGE>   29

EOG Adverse Environmental Condition, (i) EOG shall have the right (A) to agree
to remedy the EOG Adverse Environmental Condition to Michael's reasonable
satisfaction, all at EOG's sole cost and expense, in which case there shall be
no adjustment to the Purchase Price in respect of such EOG Adverse Environmental
Condition, or (B) if the Parties have agreed upon an adjustment to the Purchase
Price in respect of such EOG Adverse Environmental Condition, to reduce the
Purchase Price by the amount of such adjustment, in which event EOG shall have
no obligation or liability in respect of such EOG Adverse Environmental
Condition, and (ii) if the reasonable cost of remedying the EOG Adverse
Environmental Condition exceeds 3% of the Purchase Price, EOG shall have the
right to terminate this Agreement. If EOG receives notice from Michael of any
EOG Adverse Environmental Condition after Closing but on or before one hundred
and eighty (180) days following the Closing Date, EOG shall remedy the EOG
Adverse Environmental Condition to Michael's reasonable satisfaction, all at
EOG's sole cost and expense. EOG shall have no liability or obligation to
Michael under this Section 33(b) for any EOG Adverse Environmental Condition
for which EOG did not receive timely written notice of such condition on or
before one hundred and eighty (180) days following the Closing Date. If EOG
elects or is obligated to remedy an EOG Adverse Environmental Condition
hereunder, EOG agrees that it will exercise all reasonable efforts and diligence
to complete any required remediation within six (6) months, but any failure to
complete such effort by such time shall not relieve EOG of its duty to fully and
completely satisfy its obligation hereunder. Michael shall grant EOG and its
representatives such access to the EOG Property as may be reasonably necessary
provided such access does not interfere with Michael's operations. EOG shall
indemnify, defend and hold Michael harmless from and against any and all claims
for personal injuries, death or property damage arising from EOG's remediation
activities hereunder, including, without limitation, any claims by EOG's
employees, representatives or agents. Notwithstanding the foregoing, if EOG
elects to remedy an EOG Adverse Environmental Condition and the Parties agree in
writing on the cost of such remediation, Michael shall have the right to remedy
the EOG Adverse Environmental Condition by giving written notice to EOG within
10 days after the Parties agree on the cost of the remediation, in which event
Michael shall have assumed EOG's obligation to




                                       29
<PAGE>   30


remedy the EOG Adverse Environmental Condition, and EOG shall reimburse Michael
for all costs and expenses incurred by Michael in effecting such remediation,
but not to exceed the agreed upon cost of such remediation.

         (c) Except for any costs or expenses incurred by EOG in discharging any
remediation obligations under Section 33(b) or for which Michael is entitled to
reimbursement under the last sentence of Section 33(b), if the Closing hereunder
occurs, Michael shall indemnify, defend and hold EOG harmless from and against
any and all claims, demands, causes of action, liabilities and obligations, and
all costs and expenses (including, without limitation, reasonable attorneys'
fees) associated therewith (collectively, "Claims"), arising out of or relating
to any discharge, release, disposal, production, storage, treatment or any
activities on, in or from the EOG Property, or the migration or transportation
from any other lands to the EOG Property, whether before or after the Effective
Time, of materials or substances that are presently, or become in the future,
subject to regulation under Environmental Laws, whether such Environmental Laws
are presently existing or are hereafter enacted, INCLUDING, WITHOUT LIMITATION,
ANY SUCH CLAIMS ARISING IN WHOLE OR IN PART FROM THE SOLE OR CONCURRENT
NEGLIGENCE OR GROSS NEGLIGENCE OF EOG. The foregoing indemnity shall not be
applicable to Claims arising out of or relating to activities on the South
Callaghan Ranch Lands after the date such lands have reverted back to EOG
pursuant to the South Callaghan Ranch Lease.

contamination or condition that would require $50,000 or more of out-of-pocket
costs and expenses to remedy and that is not otherwise permanently authorized by
permit or law, resulting from any discharge, release, disposal, production,
storage, treatment, or any other activities on, in or from the MICHAEL Property,
or the migration or transportation from other lands to the MICHAEL Property,
prior to the Closing Date, of any wastes, pollutants, contaminants, hazardous

the right (A) to agree to remedy the MICHAEL Adverse Environmental Condition to
EOG's reasonable satisfaction, all at Michael's sole cost and expense, in which
case there shall be no adjustment to the Purchase Price in respect of such
MICHAEL Adverse Environmental Condition, or (B) if the Parties have agreed upon
an adjustment to the Purchase Price in respect of such Michael Adverse
Environmental Condition, to reduce the Purchase Price by the amount of such
adjustment, in which event Michael shall have no obligation or liability in
respect of such MICHAEL Adverse Environmental Condition, and (ii) if the
reasonable cost of remedying the MICHAEL Adverse Environmental Condition exceeds
3% of the Purchase Price, Michael shall have the right to terminate this
Agreement. If Michael receives notice from EOG of any MICHAEL Adverse
Environmental Condition after Closing but on or before one hundred and eighty
(180) days following the Closing Date, Michael shall remedy the MICHAEL Adverse
Environmental Condition to EOG's reasonable satisfaction, all at Michael's sole
cost and expense. Michael shall have no liability or obligation to EOG under
this Section 34(b) for any MICHAEL Adverse Environmental Condition for which
Michael did not receive timely written notice of such condition on or before one
hundred and eighty (180) days following the Closing Date. If Michael elects or
is obligated to remedy a MICHAEL Adverse Environmental Condition hereunder,
Michael agrees that it will exercise all reasonable efforts and diligence to
complete any required remediation within six (6) months, but any failure to
complete such effort by such time shall not

relieve Michael of their duty to fully and completely satisfy their obligation
hereunder. EOG shall grant Michael and its representatives such access to the
MICHAEL Property as may be reasonably necessary provided such access does not
interfere with EOG's operations. Michael shall indemnify, defend and hold EOG
harmless from and against any and all claims for personal injuries, death or
property damage arising from Michael's remediation activities hereunder,

representatives or agents. Notwithstanding the foregoing, if Michael elects to
remedy a MICHAEL Adverse Environmental Condition and the Parties agree in
writing on the cost of such remediation, EOG shall have the right to remedy the

within 10 days after the Parties agree on the cost of the remediation, in which
event EOG shall have assumed Michael's obligation to remedy the MICHAEL Adverse

BY NEGOTIATIONS BETWEEN THEMSELVES. THE NEGOTIATION PROCESS MAY BE STARTED BY
THE GIVING OF WRITTEN NOTICE BY EITHER PARTY TO THE OTHER PARTY IN ACCORDANCE
WITH THE TERMS OF SECTION 29 HEREOF. IN THE EVENT THAT EITHER PARTY DESIRES THE
INVOLVEMENT OF A MEDIATOR TO FACILITATE THE NEGOTIATIONS, THEN IT SHALL GIVE
WRITTEN NOTICE THEREOF, AND THE PARTIES AGREE, ADDITIONALLY, TO NEGOTIATE IN
GOOD FAITH TO SELECT AN INDEPENDENT MEDIATOR TO FACILITATE THE NEGOTIATIONS AND
TO CONDUCT UP TO EIGHT CONSECUTIVE HOURS OF NON-BINDING MEDIATED NEGOTIATIONS IN
HOUSTON, TEXAS WITHIN 30 DAYS AFTER THE NOTICE REQUESTING INVOLVEMENT OF A
MEDIATOR IS FIRST SENT. IF, WITHIN 10 DAYS AFTER THE NOTICE REQUESTING A
MEDIATOR, THE PARTIES ARE NOT ABLE TO AGREE UPON A MEDIATOR, THEN EITHER PARTY
MAY SEEK THE APPOINTMENT OF A MEDIATOR UNDER SUB-PARAGRAPH 40(d).

        (b) NO ARBITRATION MAY BE COMMENCED BY EITHER PARTY UNLESS AND UNTIL A
GOOD FAITH EFFORT HAS BEEN MADE TO CONDUCT NEGOTIATIONS AND, IF REQUESTED BY A
PARTY, A MEDIATION IN COMPLIANCE WITH THE FOREGOING PARAGRAPH. IF A CONTROVERSY

DISPUTE SUBMITTED. IF THE TWO APPOINTED ARBITRATORS FAIL TO TIMELY NAME A THIRD

        (d) IF THE PARTIES ARE UNABLE TO AGREE UPON A MEDIATOR OR THE PARTIES'
APPOINTED ARBITRATORS ARE UNABLE TO SELECT A THIRD ARBITRATOR, THEN EITHER PARTY

PARTY MAY REQUEST THE JUDGE OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF TEXAS, HOUSTON DIVISION, HAVING GREATEST TENURE BUT NOT ON SENIOR
STATUS TO APPOINT A MEDIATOR OR THIRD ARBITRATOR, WHO SHALL BE INDEPENDENT AND
IMPARTIAL AND QUALIFIED TO DETERMINE THE MATTERS SUBMITTED IN THAT JUDGE'S SOLE
OPINION. IF THAT JUDGE FAILS, WITHIN THIRTY (30) DAYS OF SUBMISSION OF THE
REQUEST, TO APPOINT A MEDIATOR OR THIRD ARBITRATOR, THEN EITHER PARTY MAY MAKE
THE SAME REQUEST TO THE JUDGE OF THAT COURT WITH THE NEXT GREATEST TENURE, AND
SO ON, UNTIL THE MEDIATOR IS APPOINTED AND THE PANEL OF ARBITRATORS IS
CONSTITUTED. IF, PRIOR TO RENDERING A DECISION, AN ARBITRATOR RESIGNS OR BECOMES
UNABLE TO SERVE, HE SHALL BE REPLACED AS FOLLOWS. IF HE WAS ONE OF THE TWO
ARBITRATORS APPOINTED BY THE PARTIES, THE PARTY THAT NAMED HIM SHALL NAME HIS
REPLACEMENT; PROVIDED, HOWEVER, THAT IF HIS REPLACEMENT IS NOT NAMED WITHIN
FIFTEEN (15) DAYS, THE OTHER PARTY SHALL NAME HIS REPLACEMENT. IF HE WAS THE
THIRD ARBITRATOR SELECTED BY THE TWO ARBITRATORS NAMED BY THE PARTIES, THOSE
TWO ARBITRATORS SHALL NAME HIS REPLACEMENT; PROVIDED, HOWEVER, THAT IF THEY FAIL
TO AGREE ON HIS REPLACEMENT WITHIN FIFTEEN (15) DAYS, EITHER PARTY MAY FOLLOW
THE PROCEDURE SPECIFIED IN THIS SUBPARAGRAPH (D).

        (e) THE ARBITRATION SHALL OCCUR IN HOUSTON, TEXAS AND SHALL BE CONDUCTED
IN ACCORDANCE WITH THE AMERICAN ARBITRATION ASSOCIATION'S COMMERCIAL ARBITRATION
RULES IN EFFECT AT THE TIME OF THE ARBITRATION NOTICE (THE "RULES"). THE PARTIES
AGREE THAT THEY WILL FAITHFULLY OBSERVE THIS AGREEMENT AND THE RULES AND THAT
THEY WILL ABIDE BY AND PERFORM ANY FINAL AWARD RENDERED BY THE ARBITRATORS.
ADDITIONALLY, THE ARBITRATION SHALL BE CONDUCTED IN A MANNER CONSISTENT WITH THE
FEDERAL ARBITRATION ACT, 9 U.S.C. SECTION 1 ET SEQ. (THE "FAA") OR CONSISTENT 
WITH THE SAME PRINCIPLES ENUNCIATED IN THE FAA IN THE EVENT IT MAY NOT BE
TECHNICALLY APPLICABLE; PROVIDED, HOWEVER, THAT RULES ESTABLISHED UNDER THE FAA
THAT THE PARTIES CANNOT ELECT AS APPLICABLE IF THE FAA IS NOT TECHNICALLY
APPLICABLE, SUCH AS PROCEDURAL RULES CONCERNING ENFORCEMENT OF AWARDS, ACCESS TO
THE COURTS, PROCEDURES FOR REVIEW, AND






                                       35

MATTERS CONCERNING SUBJECT MATTER JURISDICTION, SHALL NOT BE BINDING IF THE FAA
IS NOT TECHNICALLY APPLICABLE. THE CONTROVERSY OR DISPUTE SUBMITTED SHALL BE
RESOLVED BY THE DECISION OF A MAJORITY OF THE PANEL OF ARBITRATORS. THE AWARD OR
JUDGMENT OF THE PANEL SHALL BE FINAL AND BINDING ON THE PARTIES AND JUDGMENT
UPON THE AWARD OR JUDGMENT OF THE PANEL MAY BE ENTERED AND ENFORCED IN ANY COURT
HAVING JURISDICTION. NO LITIGATION OR OTHER JUDICIAL PROCEEDING MAY EVER BE
INITIATED AT ANY TIME IN ANY COURT FOR THE PURPOSE OF ADJUDICATING,
INTERPRETING, OR ENFORCING THE RIGHTS OR OBLIGATIONS OF THE PARTIES TO THIS
AGREEMENT, OR TO DETERMINE THE VALIDITY OF OR ADJUDICATE A CLAIM OF BREACH OF
THIS AGREEMENT; PROVIDED, HOWEVER, THAT THIS PROHIBITION SHALL NOT APPLY TO
LITIGATION OR OTHER JUDICIAL PROCEEDINGS UNDERTAKEN TO SEEK ENFORCEMENT OF THE
PARTIES' AGREEMENT TO ARBITRATE OR TO ENFORCE ANY ARBITRATION AWARD OR SEEK
REVIEW OF ANY ARBITRATION AWARD. REVIEW OF SUCH ARBITRATION AWARD SHALL BE
PERMITTED ONLY ON GROUNDS THAT (I) THE AWARD WAS PROCURED BY CORRUPTION, FRAUD,
OR UNDUE MEANS; (II) THERE WAS EVIDENT PARTIALITY OR CORRUPTION IN THE THIRD
APPOINTED ARBITRATOR; (III) THE PANEL WAS GUILTY OF MISCONDUCT IN REFUSING TO
HEAR EVIDENCE PERTINENT AND MATERIAL TO THE CONTROVERSY; (IV) THE PANEL EXCEEDED
THEIR POWERS; OR (V) THERE WAS NO AGREEMENT TO ARBITRATE THE MATTER SUBMITTED
AND RULED UPON AND THE PARTY AFFECTED DID NOT PARTICIPATE IN THE ARBITRATION
HEARING WITHOUT RAISING THE OBJECTION. THE PARTIES' EXPRESSLY AGREE THAT AN
AWARD SHALL IN NO OTHER RESPECT BE APPEALABLE OR SUBJECT TO REVIEW. IF EITHER
PARTY BECOMES THE SUBJECT OF A BANKRUPTCY, RECEIVERSHIP OR OTHER SIMILAR
PROCEEDING UNDER THE LAWS OF THE UNITED STATES OF AMERICA, ANY STATE OR
COMMONWEALTH OR ANY OTHER NATION OR POLITICAL SUBDIVISION THEREOF, THEN, TO THE
EXTENT PERMITTED OR NOT PROHIBITED BY APPLICABLE LAW, ANY FACTUAL OR SUBSTANTIVE
LEGAL ISSUES ARISING IN OR DURING THE PENDENCY OF ANY SUCH PROCEEDING SHALL BE
SUBJECT TO ALL OF THE FOREGOING MEDIATION AND ARBITRATION PROVISIONS AND SHALL
BE RESOLVED, TO THE EXTENT PERMITTED, IN ACCORDANCE THEREWITH. THE AGREEMENTS
CONTAINED HEREIN HAVE BEEN GIVEN FOR VALUABLE CONSIDERATION, ARE COUPLED WITH AN
INTEREST AND ARE NOT INTENDED TO BE EXECUTORY CONTRACTS. THE FEES AND EXPENSES
OF THE MEDIATOR WILL BE SHARED EQUALLY BY THE PARTIES AND THE FEES AND EXPENSES
OF THE THIRD ARBITRATOR WILL BE SHARED BY THE PARTIES ON A BASIS DETERMINED TO
BE FAIR AND EQUITABLE BY THE PANEL, TAKING INTO ACCOUNT THE RELATIVE FAULT






                                       36
<PAGE>   37
OF EACH PARTY, THE RELATIVE CREDIBILITY AND MERIT OF ALL CLAIMS AND DEFENSES
MADE BY EACH PARTY AND THE COOPERATION, SPEED AND EFFICIENCY OF EACH PARTY IN
CONDUCTING THE ARBITRATION PROCEEDINGS AND COMPLYING WITH THE RULES AND WITH THE
ORDERS AND REQUESTS OF THE PANEL.

         (f) WITHIN 10 DAYS AFTER THE SELECTION OF THE THIRD ARBITRATOR, THE
PARTIES AND THEIR COUNSEL WILL APPEAR BEFORE THE PANEL AT A PLACE AND TIME IN
HOUSTON, TEXAS AS MAY BE DESIGNATED BY THE PANEL FOR THE PURPOSE OF EACH PARTY
MAKING A ONE HOUR OR LESS PRESENTATION AND SUMMARY OF THE CASE. THEREAFTER, THE
PANEL WILL SET DATES AND TIMES FOR ADDITIONAL HEARINGS UNTIL THE PROCEEDING IS
CONCLUDED. THE DESIRE AND GOAL OF THE PARTIES IS, AND THE PANEL WILL BE ADVISED
THAT THEIR GOAL SHOULD BE, TO CONDUCT AND CONCLUDE THE ARBITRATION PROCEEDING AS
EXPEDITIOUSLY AS POSSIBLE. IF ANY PARTY OR HIS COUNSEL FAILS, WITHOUT GOOD
CAUSE, TO APPEAR AT ANY HEARING, THE PANEL SHALL BE ENTITLED TO REACH A
DECISION BASED ON THE EVIDENCE WHICH HAS BEEN PRESENTED TO HIM BY THE OTHER
PARTY WHO DID APPEAR.

         (g) ANY ARBITRAL AWARD MAY BE ENFORCED IN THE COURTS OF THE STATE OF
TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS AND,
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE PARTIES HEREBY ACCEPT FOR
THEMSELVES AND IN RESPECT OF THEIR PROPERTY, GENERALLY AND UNCONDITIONALLY, THE
NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS FOR SAID PURPOSE AND THE
PARTIES HEREBY IRREVOCABLY WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW ANY
OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE
OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH THEY MAY NOW OR HEREAFTER
HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE
JURISDICTIONS.

         (h) THE PANEL WILL HAVE NO AUTHORITY TO AWARD PUNITIVE OR OTHER DAMAGES
NOT MEASURED BY THE PREVAILING PARTY'S ACTUAL DAMAGES.

     41. BINDING EFFECT. This Agreement shall be binding upon and inure to the
benefit of the Parties and their respective successors and assigns.

THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE BEEN
ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR

Warrant No. 2                                                         Void after
                                                                 August 12, 2001


                             MICHAEL HOLDINGS, INC.

                             STOCK PURCHASE WARRANT

         This Warrant is issued, for good and valuable consideration, receipt
of which is hereby acknowledged, to Cambrian Capital Partners, L.P., a Delaware
limited partnership (the "Holder") by Michael Holdings, Inc., a Texas
corporation (the "Company").

         1.      Purchase of Shares. Subject to the terms and conditions
hereinafter set forth, the Holder is entitled, upon surrender of this Warrant
at the principal office of the Company (or at such other place as the Company
shall notify the Holder hereof in writing), to purchase from the Company 38,671
shares of its common stock (the "Common Stock").

         2.      Exercise Period. This Warrant is exercisable at any time and
from time to time and, except as provided below, shall remain so exercisable
from the date hereof until August 12, 2001 (the "Exercise Period") on which
date this Warrant shall terminate and no longer be exercisable.

         3.      Exercise Price. The exercise price (the "Exercise Price") for
the Warrants exercised shall be $8.00 per share of the Common Stock purchased
by the Holders.

         4.      Method of Exercise. While this Warrant remains outstanding and
exercisable in accordance with Sections 1 and 2 above, the Holder may exercise,
in whole or in part, the purchase rights evidenced hereby. Such exercise shall
be effected by:

                 (i)      the surrender of the Warrant, together with a duly
executed copy of a subscription notice in substantially the form of Exhibit A
attached hereto, to the Secretary of the Company at its principal offices; and

                 (ii)     the payment to the Company of an amount equal to the
aggregate Exercise Price in cash or in a certified cashier's check for the
number of shares of Common Stock being purchased.




<PAGE>   2
         Upon any such exercise, the number of shares of Common Stock
purchasable upon exercise of the Warrant shall be reduced by such designated
number of shares of Common Stock, and, if a balance of purchasable shares of
Common Stock remains after such exercise, the Company shall execute and deliver
to the Holder hereof a new Warrant for such balance of shares of Common Stock.

         5.      Exercise by Exchange of Warrant.

         (a)     In addition to and without limiting the rights of the Holder
under the terms hereof, at any time after the Common Stock is traded on a
national securities exchange the Warrant (or any subdivision thereof) may be
exercised by being exchanged in whole or in part at any time or from time to
time prior to its expiration for a number of shares of Common Stock having an
aggregate fair market value on the date of such exercise equal to the
difference between (x) the fair market value of the number of shares of Common
Stock subject to the Warrant designated by the Holder hereon on the date of the
exercise and (y) the aggregate Exercise Price of the Warrant otherwise payable
by the Holder hereof for such designated shares of Common Stock. Upon any such
exercise, the number of shares of Common Stock purchasable upon exercise of the
Warrant shall be reduced by such designated number of shares of Common Stock,
and, if a balance of purchasable shares of Common Stock remains after such
exercise, the Company shall execute and deliver to the Holder hereof a new
Warrant for such balance of shares of Common Stock. No payment of any cash or
other consideration shall be required or permitted. Such exchange shall be
effective upon the date of receipt by the Company of the original Warrant
surrendered for cancellation and a duly executed subscription notice
substantially in the form of Exhibit A attached hereto from the Holder hereof
that the exchange pursuant to this section be made. No fractional shares
arising out of the above formula for determining the number of shares issuable
in such exchange shall be issued, and the Company shall in lieu thereof make
payment to the Holder hereof of cash in the amount of such fraction multiplied
by the fair market value of the Shares on the date of exchange. Any tax
liability related to such transaction shall be paid by the Holder.

         (b)     The "fair market value" of Common Stock, as used in the
immediately preceding paragraph, shall mean, as to any exercise date, (i) the
last sale price of the Common Stock reported on a national securities exchange
or the Nasdaq National Market, (ii) the last sale price regular way for the
Common Stock as reported in the consolidated transaction reporting system on
which the Common Stock may then be listed for trading, (iii) if the Common
Stock is not quoted on the Nasdaq National Market or is not listed for trading
on a national securities exchange, the closing bid price as published by Nasdaq
(or, if such price is not so published by Nasdaq, the average of the high and
low bid prices for the Common Stock on such exercise date, as furnished by any
National Association of Securities Dealers, Inc.  ("NASD") member firm selected
from time to time by the Company for such purpose) or (iv) if the Common Stock
is not quoted on the Nasdaq National Market, is not listed for trading on a
national securities exchange or neither Nasdaq nor an NASD member firm
publishes a bid price for the Common Stock, the fair market value of the Common
Stock shall be determined in good faith by the Company as of the exercise date.





                                     - 2 -


<PAGE>   3

         If the exercise date is not a business day, then the "fair market
value" shall be calculated using the next day immediately following the
exercise date on which the national securities system, the Nasdaq National
Market or any other quotation system used to determine the "fair market value"
of the Common Stock is open for business.

         6.      Certificates for Shares. Upon the exercise of the purchase
rights evidenced by this Warrant, one or more certificates for the number of
shares of Common Stock so purchased shall be issued as soon as practicable
thereafter, and in any event within thirty (30) days of the delivery of the
subscription notice.

         7.      Representations and Covenants of Company.

         (a)     Reservation of Shares. The Company covenants that it will at
all times keep available such number of authorized shares of its Common Stock,
free from all preemptive rights with respect thereto, which will be sufficient
to permit the exercise of this Warrant for the full number of shares of Common
Stock specified herein. The Company further covenants that such shares of
Common Stock, when issued pursuant to the exercise of this Warrant, will be
duly and validly issued, fully paid and non-assessable shares of Common Stock
and free from all taxes, liens and charges with respect to the issuance
thereof.

         (b)     Authorized, Issued and Outstanding Shares. The authorized
capital stock of the Company consists solely of 100,000,000 shares of Common
Stock, $0.01 par value, of which 773,425 shares are issued and outstanding and
226,575 shares are held in its treasury, and 50,000,000 shares of preferred
stock of which -0- shares are issued and outstanding. There are no outstanding
or authorized options, warrants (other than this Warrant and that certain
Warrant to Purchase Shares of Common Stock granted to Dale L. Schwarzhoff for
15,000 shares of Common Stock, subject to adjustment as provided therein),
subscriptions, calls, conversions or other rights, contracts, agreements or
commitments or undertakings of any kind (except for options which may be
granted under the Company's 1998 Stock Option Plan) obligating the Company to
issue, sell, purchase, or redeem any shares of capital stock of the Company or
any other securities convertible into, exchangeable for or evidencing the right
to subscribe to any shares of capital stock or other ownership interest in the
Company.

         (c)     Issuance of Stock Options. The Company hereby covenants that
any stock options granted by the Company pursuant to the Company's 1998 Stock
Option Plan (the "Plan") to purchase any of the shares of Common Stock reserved
for issuance under the Plan, shall have an exercise price which shall not be
less than the fair market value of the Common Stock on the date of grant of
such stock options.

         8.      Anti-Dilution. The number of and kind of shares of Common
Stock purchasable upon exercise of this Warrant (with respect to subsection (c)
below) and the Exercise Price shall be subject to adjustment from time to time
as follows:





                                     - 3 -
<PAGE>   4
         (a)     Subdivisions, Combinations and Issuance of Additional Shares.
If the Company shall at any time prior to the expiration of this Warrant (i)
subdivide its Common Stock by split-up or otherwise, (ii) combine its Common
Stock or (iii) issue additional shares of authorized but unissued Common Stock
for cash or non-cash consideration less than the Exercise Price, the number of
shares of Common Stock available upon the exercise of the Warrant shall be
proportionately increased in the case of any subdivision or issuance of
additional shares or proportionately decreased in the case of a contribution.
Appropriate adjustments shall also be made to the purchase price payable per
share, but the aggregate purchase price payable for the total number of shares
of Common Stock purchasable under this Warrant (as adjusted) shall remain the
same. Any adjustment under this Section 8(a) shall become effective at the
close of business on the date the subdivision or combination becomes effective.

         (b)     Stock Dividends and Distributions. In case the Company shall
at any time while this Warrant is outstanding and unexpired pay a dividend with
respect to Common Stock payable in shares of such stock, or make any other
distribution of securities or property with respect to such stock (except any
distribution provided for in Section 8(a) or 8(c) herein), then (A) the
Exercise Price in effect immediately prior to the record date for distribution
of such dividend or in the event that no record date is fixed, upon the making
of such dividend shall be adjusted to that price determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction
(i) the numerator of which shall be the total number of shares of such stock
outstanding immediately prior to such dividend and (ii) the denominator of
which shall be the total number of shares of such stock outstanding immediately
after such dividend and (B) the number of shares of Common Stock purchasable
under this Warrant in effect immediately prior to the record date for
distribution of such dividend or in the event no record date is fixed, upon the
making of such dividend shall be adjusted to that number of shares determined
by multiplying the number of shares of Common Stock purchasable under this
Warrant immediately prior to such record date by a fraction, (i) the numerator
of which shall be the total number of shares of Common Stock outstanding
immediately after such dividend and (ii) the denominator of which shall be the
total number of shares of Common Stock outstanding immediately prior to such
dividend; provided, however, that in no event shall any adjustment to the
Exercise Price or number of shares of Common Stock purchasable under this
Warrant be made upon the payment of a cash dividend or cash distribution or
interest payment by the Company on any of its securities.

         (c)     Reclassification, Reorganization and Consolidation. In case of
any reclassification, conversion, capital reorganization, consolidation or
merger with or into any other entity (including, without limitation, any
transaction or series of transactions whereby the Company becomes a subsidiary
of another entity), transfer of all or substantially all of the properties or
assets of the Company or its Subsidiaries, or change in the Common Stock (other
than as provided for in Sections 8(a) and (b) above), then, as a condition of
such reclassification, conversion, reorganization, consolidation, merger,
transfer or change, as the case may be, lawful provision shall be made, and
duly executed documents evidencing the same from the Company or its successor
shall be delivered to the Holder of this Warrant, so that such Holder shall
have the right at any time prior to the expiration of this Warrant to purchase,
at a total price equal to that payable upon the exercise of this Warrant, the
kind and amount of shares of stock and other securities and property receivable
in





                                     - 4 -


<PAGE>   5
connection with such reclassification, conversion, reorganization,
consolidation, merger, transfer or change, as the case may be, by a holder of
the same number of shares of Common Stock as were purchasable by the Holder of
this Warrant immediately prior to such reclassification, conversion,
reorganization, consolidation, merger, transfer or change, as the case may be.
In any such case appropriate provisions shall be made with respect to the
rights and interest of the Holder of this Warrant so that the provisions hereof
shall thereafter be applicable with respect to any shares of stock or other
securities and property deliverable upon exercise hereof, and appropriate
adjustments shall be made to the purchase price per share payable hereunder,
provided the aggregate purchase price shall remain the same. Upon any
reorganization, consolidation, merger or transfer referred to in this Section
8(c), this Warrant shall continue in full force and effect and the terms hereof
shall be applicable to the shares of stock, other securities and property
receivable on the exercise of this Warrant after the consummation of such
reorganization, consolidation, merger or transfer, as the case may be and shall
be binding upon the issuer of any such stock or other securities including, in
the case of any such transfer, the person acquiring all or substantially all of
the properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant.

         (d)     No Dilution or Impairment. The Company covenants that it will
not, by amendment of its articles of incorporation, or through any
reorganization, transfer of assets, consolidation, merger, dissolution, or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the holder of
this Warrant against dilution or other impairment. Without limiting the
generality of the foregoing, the Company covenants that it (i) will not
increase the par value of any shares of stock receivable on the exercise of the
Warrant above the amount payable therefor on such exercise, (ii) will take all
such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of stock on the
exercise of the Warrant, and (iii) will not consolidate with or merge with or
into any other entity or permit any such entity to consolidate with or merge
into the Company (if the Company is not the surviving entity), or permit the
creation of, or allow its shareholders to create, an entity which is a holding
company or a parent corporation or other entity holding all of the Company's
equity securities, unless such other entity shall expressly assume in writing
and will be bound by all the terms of this Warrant.

         (e)     Notice of Adjustment. When any adjustment is required to be
made in the number or kind of shares purchasable upon exercise of the Warrant,
or in the Exercise Price, the Company shall promptly notify the Holder of such
event and of the number of shares of Common Stock or other securities or
property thereafter purchasable upon exercise of the Warrant.

         9.      No Fractional Shares. No fractional shares shall be issued
upon the exercise of this Warrant, and the number of shares of stock issued
upon exercise of this Warrant shall be rounded to the nearest whole share.

         10.     No Stockholder Rights. Prior to the exercise of this Warrant,
the Holder shall not be entitled to any rights of a shareholder with respect to
the shares of Common Stock purchasable





                                     - 5 -

<PAGE>   6
hereunder, including (without limitation) the right to vote such shares,
receive dividends or other distributions thereon, or be notified of shareholder
meetings, and such Holder shall not be entitled to any notice or other
communication concerning the business or affairs of the Company.

         11.     Exchange of Warrant. Subject to any restriction upon transfer
set forth in this Warrant, each Warrant may be exchanged for another Warrant or
Warrants of like tenor and representing in the aggregate a like number of
Warrants. Any Holder desiring to exchange a Warrant or Warrants shall make such
request in writing delivered to the Company, and shall surrender, properly
endorsed, the Warrant or Warrants to be so exchanged.

         12.     Mutilated or Missing Warrants. In case any Warrant shall be
mutilated, lost, stolen or destroyed, the Company shall issue and deliver in
exchange and substitution for and upon cancellation of the mutilated Warrant,
or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new
Warrant of like tenor and representing an equivalent right or interest, but
only upon receipt of evidence reasonably satisfactory to the Company of such
loss, theft or destruction of such Warrant and indemnity or bond, if requested,
also reasonably satisfactory to the Company. An applicant for such substitute
Warrant shall also comply with such other reasonable regulations and pay such
other reasonable charges as the Company may prescribe.

         13.     Payment of Taxes. The Company will pay all taxes (other than
any income taxes or other similar taxes), if any, attributable to the initial
issuance of the Warrant and the issuance of the shares of Common Stock upon
the exercise of the Warrant, provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of the
issuance or delivery of any Warrant, or the transfer thereof, and no such
issuance, delivery or transfer shall be made unless and until the person
requesting such issuance or transfer has paid to the Company the amount of any
such tax, or has established, to the satisfaction of the Company, that no such
tax is payable or such tax has been paid.

         14.     Warrant Register. The Warrants shall be numbered and shall be
registered in a Warrant Register (hereinafter defined) as they are issued. The
Company shall be entitled to treat the registered holder of any Warrant on the
Warrant Register as the owner in fact thereof for all purposes and shall not be
bound to recognize any equitable or other claim to or interest in such Warrant
on the part of any other person, and shall not be liable for any registration
or transfer of Warrants which are registered or to be registered in the name of
a fiduciary or the nominee of a fiduciary unless made with the actual knowledge
that a fiduciary or nominee is committing a breach of trust in requesting such
registration of transfer, or with knowledge of such facts that its
participation therein amounts to bad faith.

         15.     Transfer of Warrants.

         (a)     By accepting this Warrant, the Holder hereby agrees that such
Warrant, and any shares of Common Stock issuable hereunder, will be held for
investment purposes only and not with a view to resell. This Section 15(a)
shall be binding upon the Holder and its heirs, successors and assigns.





                                     - 6 -
<PAGE>   7
         (b)     Notwithstanding Section 15(a) or any other provision herein
contained, the Warrants shall be transferable on the books of the Company (the
"Warrant Register") only upon delivery thereof duly endorsed by the Holder or
by his duly authorized attorney or representative, or accompanied by proper
evidence of succession, assignment or authority to transfer. In all cases of
transfer by an attorney, the original power of attorney, duly approved, or an
official copy thereof, duly certified shall be deposited with the Company.
In case of transfer by executors, administrators, guardians or other legal
representatives, duly authenticated evidence of their authority shall be
produced, and may be required to be deposited with the company in its
discretion. Upon any registration of transfer, the Company shall deliver a
new Warrant or Warrants to the person entitled thereto. Notwithstanding the
foregoing, the Company shall have no obligation to cause a Warrant to be
transferred on its books to any person, unless (i) such Warrant and the shares
of Common Stock issuable upon exercise of such Warrant are registered under a
valid and effective registration statement under the Securities Act of 1933,
as amended, and applicable state blue sky laws or (ii) the Company receives a
written opinion of counsel satisfactory to the Company that registration is not
required under such act. Any shares of Common Stock issued pursuant to this
Warrant shall bear legends describing, among other things, restrictions on
transfer.

         16.     Registration Rights.

         16.1    Registration Under the Securities Act of 1933. Upon exercise,
in part or in whole, of the Warrants, certificates representing the shares
Common Stock and any other securities issuable upon exercise of the Warrants
(collectively, the "Warrant Securities") shall bear the following legend:

         The securities represented by this certificate may not be offered or
         sold except pursuant to (i) an effective registration statement under
         the Act, (ii) to the extent applicable, Rule 144 under the Act (or
         any similar rule under such Act relating to the disposition of
         securities), or (iii) an opinion of counsel, if such opinion shall be
         reasonably satisfactory to counsel to the issuer, that an exemption
         from registration under such Act is available.

         16.2    Piggyback Registration. If, at any time commencing after the
date hereof the Company registers any of its securities under the Securities
Act of 1933, as amended, or any successor statute thereto (the "Act") (such
period being hereinafter referred to as the "Registration Period"), the Company
proposes to register any of its securities under the Act (other than in
connection with a transaction contemplated by Rule 145(a) promulgated under the
Act or pursuant to Form S-4, Form S-8 or any successor form thereto) it will
give written notice by registered mail, at least thirty (30) days prior to the
filing of each such registration statement, to all Holders of the Warrants
and/or the Warrant Securities of its intention to do so. If the Holders of the
Warrants and/or Warrant Securities notify the Company within fifteen (15) days
after receipt of any such notice of its or their desire to include any such
securities in such proposed registration statement, the Company shall afford
the Holders of the Warrants and/or Warrant Securities the opportunity to have
such Warrant Securities registered under such registration statement, except as
otherwise provided herein. In the case of the registration of shares of its
common stock by the Company in





                                     - 7 -

<PAGE>   8
connection with an underwritten public offering, the Company shall not be
required to register Warrant Securities in excess of the amount, if any, of
Warrant Securities that the principal underwriter of an underwritten offering
shall reasonably and in good faith agree in writing to include in such
offering.

         Notwithstanding the provisions of this Section 16.2, the Company shall
have the right at any time after it shall have given written notice pursuant to
this Section 16.2 (irrespective of whether a written request for inclusion of
any such securities shall have been made) to elect not to file any such
proposed registration statement, or to withdraw the same after the filing but
prior to the effective date thereof.

         16.3    Demand Registration.

         (a)     At any time during the Exercise Period, the Holders of the
Warrant Securities representing 51% of the Common Stock (assuming the exercise
of all of the Warrants), issued pursuant to this Warrant shall have the right
(which right is in addition to the registration rights under Section 16.2
hereof), exercisable by written notice to the Company, to have the Company
prepare and file with the Commission, on one occasion, a registration statement
and such other documents, including a prospectus, as may be necessary in the
opinion of both counsel for the Company and counsel for the Underwriter and
Holders, in order to comply with the provisions of the Act, so as to permit a
public offering and sale of their respective Warrant Securities for twelve (12)
consecutive months by such Holders and any other Holders of the Warrants and/or
Warrant Securities who notify the Company within ten (10) days after receiving
notice from the Company of such request. Anything herein to the contrary
notwithstanding, the Company shall be obligated to take any action to comply
with this Section 16.3 on only one occasion.

         (b)     The Company covenants and agrees to give written notice of any
registration request under this Section 16.3 by the majority of the Holders to
all other a registered Holders of the Warrants and the Warrant Securities
within ten (10) days from the date of the receipt of any such registration
request.

         (c)     In addition to the registration rights under Section 16.2 and
subsection (a) of this Section 16.3, at any time commencing after and expiring
ten (10) years thereafter, any Holder of Warrants and/or Warrant Securities
shall have the right, exercisable by written request to the Company, to have
the Company prepare and file, on one occasion, with the Commission a
registration statement so as to permit a public offering and sale for twelve
(12) consecutive months by any such Holder of its Warrant securities; provided,
however, that the provisions of Section 16.4(b) hereof shall not apply to any
such registration request and registration and all costs incident thereto shall
be at the expense of the Holder or Holders making such request.

         (d)     Notwithstanding anything to the contrary contained herein, if
the Company shall not have filed a registration statement for the Warrant
Securities within forty-five (45) days of the receipt of the written notice
specified in Section 16.3(a), the Company agrees that upon written notice by the
Holders of the Warrants and/or Warrant Securities representing more than 50% of
the





                                     - 8 -

<PAGE>   9
Warrants and the Warrant Securities, at that time outstanding (assuming the
exercise of all of the Warrants) it shall repurchase (i) any and all Warrant
Securities at the higher of the fair market value (as defined in Section 5(b))
per share of Common Stock on (x) the date of the notice sent pursuant to
Section 16.3(a) or (y) the expiration of the period specified in Section
16.4(a) and (ii) any and all Warrants at such fair market value less the
exercise prices of such Warrants. Such repurchase shall be in immediately
available funds and shall close within two (2) days after the latter of (i) the
expiration of the period specified in Section 16.4(a) of (ii) the delivery of
the written notice of election specified in this Section 16.3(d).

         16.4     Covenants of the Company With Respect to Registration. In
connection with any registration under Section 16.2 or 16.3 hereof, the Company
covenants and agrees as follows:

         (a)     The Company shall use its best efforts to file a registration
statement within thirty (30) days of receipt of any demand pursuant to Section
16.3, shall use its good faith efforts to have any registration statements
declared effective at the earliest possible time, and shall furnish each Holder
desiring to sell Warrant Securities such number of prospectus as shall
reasonably be requested.

         (b)     The Company shall pay all costs (excluding transfer taxes, if
any, and fees and expenses of Holder(s)' counsel and any underwriting or
selling commissions), fees and expenses in connection with all registration
statements filed pursuant to Sections 16.2 and 16.3(a) hereof including,
without limitation, the Company's legal and accounting fees, printing expenses,
blue sky fees and expenses. The Holder(s) will pay all costs, fees and expenses
in connection with any registration statement filed pursuant to Section
16.3(c). If the Company shall fail to comply with the provisions of Section
16.4(a), the Company shall, in addition to any other equitable or other relief
available to the Holder(s), be liable for any or all incidental, special and
consequential damages and damages due to loss of profit sustained by the
Holder(s) requesting registration of their Warrant Securities.

         (c)     The Company will take all necessary action which may be
required in qualifying or registering the Warrant Securities included in a
registration statement for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holder(s), provided that
the Company shall not be obligated to execute or file any general consent to
service of process or to qualify as a foreign corporation to do business under
the laws of any such jurisdiction.

         (d)     The Company shall indemnify the Holder(s) of the Warrant
Securities to be sold pursuant to any registration statement and each person,
if any, who controls such Holders within the meaning of Section 15 of the Act
or Section 20(a) of the Securities Exchange Act of 1934, as amended ("Exchange
Act"), against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act,
the Exchange Act or otherwise, arising from such registration statement, as a
result of any violation by the Company of the Act, any state securities or
"blue sky" laws or any rule or regulation thereunder, except to the extent the
Company is to be indemnified for such items pursuant to Section 16.4(e) below.

         (e)     The Holder(s) of the Warrant Securities to be sold pursuant to
the registration statement, and their successors and assigns, shall severally,
and not jointly, indemnify the Company, its officers and directors and each
person, if any, who controls the Company within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act, against all loss, claim, damage
or expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, for specific inclusion in such registration statement.

         (f)     Nothing contained in this Agreement shall be construed as
requiring the Holder(s) to exercise their Warrants prior to the initial filing
of any registration statement or the effectiveness thereof.

         (g)     The Company shall not permit the inclusion of any securities
other than the Warrant Securities and Securities issued by the Company to be
included in any registration statement filed pursuant to Section 16.3 hereof,
without the prior written consent of the Underwriter.

         (h)     With respect to a registration statement filed pursuant to
Sections 16.3, the Company shall furnish to each Holder participating in the
offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (ii) a "cold comfort" letter
dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, a letter dated the date
of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company's financial
statements included in such registration statement, in each case covering
substantially the same matters with respect to such registration statement (and
the prospectus included therein) and, in the case of such accountants' letter,
with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of
securities.

         (i)     The Company shall as soon as practicable after the effective
date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with Section 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement.

         (j)     The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence and memoranda
described below and the managing underwriter copies of all correspondence
between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect
to the registration statement and permit each Holder and underwriter to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration





                                     - 10 -

statement as it deems reasonably necessary to comply with applicable securities
laws and rules of the National Association of Securities Dealers, Inc.
("NASD"). Such investigation shall include access to books, records and
properties and opportunities to discuss the business of the Company with its
officers and independent auditors, all to such reasonable extent and at such
reasonable times and as often as any such Holder shall reasonably request.

         (k)     With respect to a registration statement filed pursuant to
Section 16.3, the Company shall enter into an underwriting agreement with the
managing underwriter, reasonably satisfactory to the Company, selected for such
underwriting by Holders holding a majority of the Warrant Securities requested
to be included in such underwriting. Such agreement shall be satisfactory in
form and substance to the Company, each Holder and such managing underwriters,
and shall contain such representations, warranties and covenants by the Company
and such other terms as are customarily contained in agreements of that type
used by the managing underwriter. The Holders shall be parties to any
underwriting agreement relating to an underwritten sale of their Warrant
Securities and may, at their option, require that any or all of the
representations, warranties and covenants of the Company to or for the benefit
of such underwriters shall also be made to and for the benefit of such Holders.
Such Holders shall not be required to make any representations or warranties to
or agreements with the Company or the underwriters except as they may relate to
such Holders and their intended methods of distribution.

         16.5    Public Sale without Registration. In no event shall the
Company be obligated to register any Warrant Securities if, in the opinion of
counsel to the Company, in form and substance acceptable to Holders, all of the
Warrant Securities proposed to be registered may be sold publicly without
restrictions and without registration under the Act.

         17.     Successors and Assigns. The terms, provisions and rights
evidenced by this Warrant shall inure to the benefit of, and be binding upon,
the Company and the Holder and their respective successors and assigns.

         18.     Amendments and Waivers. Except for the number of shares
purchasable under this Warrant and except for the Exercise Price (as set forth
in Section 3 hereof), any term of this Warrant may be amended and the
observance of any term of this Warrant may be waived (either generally or in a
particular instance and either retroactively or prospectively), with the
written consent of the Company and the holders of sixty-six and two thirds (66
2/3%) of the total number of shares of Common Stock issuable pursuant to this
Warrant and other warrants of like tenor and effect (except for variations
necessary to express the name of the holder) issued of even date herewith. Any
waiver or amendment effected in accordance with this section shall be binding
upon each holder of any shares of Common Stock purchased under this Warrant at
the time outstanding (including securities into which such Shares have been
converted), each future holder of all such shares of Common Stock, and the
Company.

         19.     GOVERNING LAW. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED
AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO THE POSSIBLE APPLICATION OF PRINCIPLES OF CONFLICT OF LAWS.

OR ANY TRANSACTION CONTEMPLATED THEREBY, BEFORE OR AFTER MATURITY.

         22.     Arbitration.

         (a) Holder and the Company (the "parties") will attempt in good 
faith to resolve any controversy or dispute arising out of or relating to
this Agreement promptly by negotiations between themselves. The negotiation
process may be started by the giving of written notice by any party to the
other parties in accordance with the terms of Section 20 hereof, and the
parties agree to negotiate in good faith, and select an independent mediator to
facilitate the negotiations and conduct up to eight consecutive hours of
mediated negotiations in Houston, Texas within 30 days after the notice is
first sent. If, within 10 days after the initial notice, the parties are not
able to agree upon





                                     - 12 -
<PAGE>   13
a mediator, the party originally giving the notice shall promptly notify
American Arbitration Association ("AAA"), 140 West 51st Street, New York, New
York 10020-1203 [telephone (212) 484-3266; fax (212) 307-4387], AAA will
promptly designate a mediator who is independent and impartial, and AAA's
decision about the identity of the mediator will be final and binding.

         (b)     No arbitration may be commenced by any party unless and until
a negotiation complying with the foregoing paragraph has been completed, and no
litigation or other proceeding may ever be instituted at any time in any court
for the purpose of adjudicating, interpreting or enforcing any rights or
obligations of the parties hereto or any rights or obligations relating to the
subject matter hereof, whether or not covered by the express terms of this
Agreement, or for the purpose of adjudicating a breach or determination of the
validity of this Agreement, or for the purpose of appealing any decision of an
arbitrator, except a proceeding instituted for the sole purpose of having the
award or judgment or an arbitrator entered and enforced.

         (c)     If a controversy or dispute is not resolved after completion
of the negotiation process described above, then, upon notice by any party to
the other parties (an "Arbitration Notice") and to AAA, the controversy or
dispute shall be submitted to a sole arbitrator who is independent and
impartial, for binding arbitration in Houston, Texas, in accordance with AAA's
Commercial Arbitration Rules (the "Rules"). The parties agree that they will
faithfully observe this Agreement and the Rules and that they will abide by and
perform any award rendered by the arbitrator. The arbitration shall be governed
by the Federal Arbitration Act, 9 U.S.C. Section 1-16 (or by the same
principles enunciated by such Act in the event it may not be technically
applicable). The award or judgment of the arbitrator shall be final and binding
on all parties and judgment upon the award or judgment of the arbitrator may be
entered and enforced by any court having jurisdiction. If any party becomes the
subject of a bankruptcy, receivership or other similar proceeding under the
laws of the United States of America, any state or commonwealth or any other
nation or political subdivision thereof, then, to the extent permitted or not
prohibited by applicable law, any factual or substantive legal issues arising
in or during the pendency of any such proceeding shall be subject to all of the
foregoing mandatory mediation and arbitration provisions and shall be resolved
in accordance therewith. The agreements contained herein have been given for
valuable consideration, are coupled with an interest and are not intended to be
executory contracts. The fees and expenses of the arbitrator will be shared by
all parties engaged in the dispute or controversy on a basis determined to be
fair and equitable by the arbitrator, taking into account the relative fault of
each party, the relative credibility and merit of all claims and defenses made
by each party and the cooperation, speed and efficiency of each party in
conducting the arbitration proceedings and complying with the Rules and with
orders and requests of the arbitrator.

         (d)     Promptly after the Arbitration Notice is given, AAA will
select three possible arbitrators with experience in the subject matter of the
controversy, to whom AAA will give the identifies of the parties and the
general nature of the controversy. If any of those arbitrators disqualifies
himself or declines to serve, AAA shall continue to designate potential
arbitrators until the parties have three to select from. After the panel of
three potential arbitrators has been completed, a two-page summary of the
background of each of the potential arbitrators will be given to each of the
parties, and the parties will have a period of 10 days after receiving the
summaries in





                                     - 13 -
<PAGE>   14
which to attempt to agree upon the arbitrator to conduct the arbitration. If
the parties are unable to agree upon an arbitrator, then one of the parties
shall notify AAA, and AAA shall select the arbitrator from one of the three, or
less, if one or more has been found to be disqualified or removes himself from
consideration (if all three are disqualified or remove themselves, then AAA
shall start the arbitration-selection process over again). The decision of AAA
with respect to the selection of the arbitrator will be final and binding in
such case.

         (e)     Within 10 days after the selection of the arbitrator, the
parties and their counsel will appear before the arbitrator at a place and time
in Houston, Texas, as may be designated by the arbitrator for the purpose of
each party making a one hour or less presentation and summary of the case.
Thereafter, the arbitrator will set dates and times for additional hearings
until the proceeding is concluded. The desire and goal of the parties is, and
the arbitrator will be advised that his goal should be, to conduct and conclude
the arbitration proceeding as expeditiously as possible. If any party or his
counsel fails to appear at any hearing, the arbitrator shall be entitled to
reach a decision based on the evidence which has been presented to him by the
parties who did appear.

         (f)     Any arbitral award may be enforced in the courts of the state
of New York or of the United States of America for the Southern District of New
York, and, by execution and delivery of this Agreement, the parties hereby
accept for themselves and in respect of their property, generally and
unconditionally, the nonexclusive jurisdiction of the aforesaid courts for said
purpose and the parties hereby irrevocably waive to the fullest extent
permitted by law any objection, including without limitation, any objection to
the laying of venue or based on the grounds of forum non conveniens, which they
may now or hereafter have to the bringing of any such action or proceeding in
such respective jurisdictions.

         (g)     The arbitrator will have no authority to award punitive or
other damages not measured by the prevailing party's actual damages and may
not, in any event, make any ruling, finding, or award that does not conform to
the terms and conditions of the this Warrant.

         (h)     The provisions of this Section 22 relating to arbitration of
disputes shall not apply to the enforcement of any rights or obligations in
connection with this Warrant.

         23.     Successors and Assigns. Subject to the provisions in Section
14, this Warrant and the rights evidenced hereby shall inure to the benefit of
and be binding upon the successors of the Company and the successors and
assigns of Holder.

         24.     Severability. Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.

         25.     Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

                                                                    EXHIBIT 10.8

                              INDEMNITY AGREEMENT

         This Indemnity Agreement ("Agreement") is made and entered into by and
between Michael Holdings, Inc. a Texas corporation ("Company"), and
______________ ("Indemnitee") (together, the "Parties").

                                  INTRODUCTION

         Indemnitee is a director of the Company.  The Parties desire that the
Company provide indemnification (including advancement of expenses) to
Indemnitee against any and all liabilities asserted against Indemnitee to the
fullest extent permitted by the Texas Business Corporation Act - ("Act"), as
the Act presently exists and may be expanded from time to time.  Based on such
premise, and for certain good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Parties hereby agree as
follows:

         1.      Continued Service.  Indemnitee will serve as a director of
the Company for so long as Indemnitee is duly elected and qualified in
accordance with the Bylaws of the company or until Indemnitee tenders his
registration to the Company.

         2.      Indemnification.  The Company shall indemnify Indemnitee when
he was, is or is threatened to be made a named defendant or respondent in a
proceeding because Indemnitee is or was a director of the Company but only if
it is determined in accordance with Section 5 below that Indemnitee:

         2.1     conducted himself in good faith;

         2.2     reasonably believed:

         (i)     in the case of conduct in his official capacity as a director
         of the Company, that his conduct was in the Company's best interests;
         and

         (ii)    in all other cases, that his conduct was at least not opposed
         to the Company's best interests; and

         2.3     in the case of any criminal proceeding, had no reasonable
cause to believe his conduct was unlawful.

         The termination of a proceeding by judgment, order, settlement or
conviction, or on a plea of nolo contendere or its equivalent is not of itself
determinative that Indemnitee did not meet the requirements set forth in this
Section 2.

         3.      Limitation on Indemnification.  Except to the extent permitted
by Section 4 below, Indemnitee shall not be indemnified under Section 2 above
in respect of a proceeding:

         3.1     in which Indemnitee is found liable on the basis that personal
benefit was improperly received by him, whether or not the benefit resulted
from an action taken in his official capacity; or

         3.2     in which Indemnitee is found liable to the Company.
<PAGE>   2
         For the purposes hereof, Indemnitee shall be deemed to have been found
liable in respect of any claim, issue or matter only after the Indemnitee shall
have been so adjudged by a court of competent jurisdiction after exhaustion of
all appeals therefrom.

         4.      Extent of Indemnification.  If Indemnitee is entitled to
indemnification under Section 2, the Company shall indemnify Indemnitee against
judgments, penalties (including excise and similar taxes), fines, settlements
and reasonable expenses actually incurred by Indemnitee in connection with the
proceeding; however, if the Indemnitee is found liable to the Company or is
found liable on the basis that personal benefit was improperly received by
Indemnitee, the indemnification (1) shall be limited to reasonable expenses
actually incurred by Indemnitee in connection with the proceeding, and (2)
shall not be made in respect of any proceeding in which Indemnitee shall have
been found liable for willful or intentional misconduct in the performance of
Indemnitee's duty to the Company.  The reasonableness of the Indemnitee's
expenses contemplated in this Section 4 shall be determined in the same manner
that the determination of indemnification is made under Section 5.

         5.      Determination of Indemnification.

         5.1     a determination of whether Indemnitee is entitled to
indemnification under Section 2 shall be made:

         (i)     by the Board of Directors of the Company by a majority vote of
         a quorum consisting of directors who at the time of the vote are not
         named defendants or respondents in the proceeding;

         (ii)    if such a quorum cannot be obtained, by a majority vote of a
         committee of the Board of Directors, designated to act in the matter
         by a majority vote of all directors, consisting sole of two or more
         directors who at the time of the vote are not named defendants or
         respondents in the proceeding;

         (iii)   by special legal counsel selected by the Board of Directors or
         a committee of the Board of Directors by vote as set forth in
         paragraphs 5.1(i) or 5.1(ii) of this Section 5, or, if such a quorum
         cannot be obtained and such a committee cannot be established, by a
         majority vote of all directors; or

         (iv)    by the shareholders in a vote that excludes the shares held by
         directors who are named defendants or respondents in the proceeding.

         5.2      the Board of Directors, independent legal counsel or
shareholders, as the case may be, shall make such determination of
indemnification under paragraph (a) of this Section 5 in accordance with the
following procedures:

         (i)     Indemnitee may submit to the Board of Directors a sworn
         statement Request for Indemnification, substantially in the form of
         Exhibit A, in which the Indemnitee requests indemnification from the
         Company pursuant to this Agreement and states that he has met the
         standard of conduct required for indemnification under Section 2.

         (ii)    The Indemnitee's submission of a Request for Indemnification
         to the Board of Directors shall create a rebuttable presumption that
         the Indemnitee has met the
<PAGE>   3
         requirements set forth in Section 2 and, therefore, is entitled to
         indemnification thereunder.  The directors, special legal counsel or
         shareholders, as the case may be, shall determine, within 30 days
         after submission of the Request for Indemnification, specifically that
         the Indemnitee is so entitled unless they or it possess clear and
         convincing evidence to rebut the foregoing presumption, which evidence
         shall be disclosed to the Indemnitee with particularity.

         6.      Mandatory Indemnification for Reasonable Expenses upon
Successful Defense.  The Company shall indemnify Indemnitee against reasonable
expenses incurred by him in connection with a proceeding in which he is a named
defendant or respondent because he is or was a director of the Company if he
has been wholly successful, on the merits or otherwise, in the defense of the
proceeding.  The reasonableness of the Indemnitee's expenses contemplated in
this Section 6 shall be determined in any manner set forth in Section 5.

         7.      Advancement of Reasonable Expenses.  Reasonable expenses
incurred by Indemnitee who was, is or is threatened to be made a named
defendant or respondent in a proceeding shall be paid or reimbursed by the
Company, in advance of the final disposition of the proceeding, without the
determination specified in Section 5 or the determination as to the
reasonableness of such expenses contemplated in Sections 4 and 6, within 14
days after:  the Company receives from Indemnitee, the Statement of
Undertaking, substantially in the form of Exhibit B, in which Indemnitee shall
state that he believes in good faith that he has met the standard of conduct
necessary for indemnification under Section 2, and (ii) the Indemnitee, or any
other person on behalf of Indemnitee, shall undertake to repay the amount paid
or reimbursed by the Company if it is ultimately determined that he has not met
those requirements or if it is ultimately determined that the indemnification
of Indemnitee against expenses incurred by him in connection with that
proceeding is prohibited by Section 5.

         8.      Merger, Consolidation or Change in Control.  If the Company is
a constituent corporation in a merger or consolidation, whether the Company is
the resulting or surviving corporation or is absorbed as a result thereof, or
if there is a change in control of the Company, Indemnitee shall stand in the
same position under this Agreement with respect to the resulting, surviving or
changed corporation as Indemnitee would have with respect to the Company if its
separate existence had continued or if there had been no change in the control
of the Company.

Accordingly, to the extent permitted by law, if the Act permits greater
indemnity than the indemnity set forth herein, or if any amendment is made to
the Act expanding the indemnity permissible under Texas law, the indemnity

         12.     Miscellaneous Provisions.

         12.1    Survival.  The provisions of this Agreement shall survive the

         12.2    Entire Agreement.  This Agreement constitute the full
         understanding of the Parties and a complete and exclusive statement of
         the terms and conditions of their agreement relating to the subject
         matter hereof and supersedes all prior negotiations, understandings
         and agreements, whether written or oral, between the Parties, their

         12.3    Amendments and Waivers.  No alteration, modification,
         amendment, change or waiver of any provision of this Agreement shall

         writing and is executed by all Parties hereto.

         12.4    Modification and Severability.  If a court of competent
         jurisdiction declares that any provision of this Agreement is illegal,
         invalid or unenforceable, then such provision shall be modified
         automatically to the extent necessary to make such provision fully
         legal, valid or enforceable.  If such court does not modify any such
         provision as contemplated herein, but instead declares it to be wholly
         illegal, invalid or unenforceable, then such provision shall be
         severed from this Agreement, this Agreement and the rights and
         obligations of the Parties hereto shall be construed as if this
         Agreement did not contain such severed provision, and this Agreement
         otherwise shall remain in full force and effect.

         12.5    Enforceability.  This Agreement shall be enforceable by and
         against the Company, the Indemnitee and their respective executors,

         Parties hereto in multiple counterparts, each of which shall be deemed
         an original for all purposes, and all of which together shall
         constitute one and the same instrument.


The parties hereto have executed this Agreement to be effective as of December
4, 1996.

                 SOUTH CALLAGHAN RANCH (LOBO) ASSETS AGREEMENT


         THIS AGREEMENT (the "Agreement") is made and entered into between
Mobil Exploration & Producing U.S. Inc.  acting as Agent for Mobil Producing
Texas & New Mexico Inc. ("Mobil") and Michael Petroleum Corporation
("Michael").  In consideration of the mutual benefits and covenants contained
herein, the parties agree as follows:

         The following Exhibits are attached hereto and shall be considered a
part of this Agreement:

         Exhibit "A" --                    Description of the McElroy Lease,
                                           the GBGL&C Lease, and the Oil and
                                           Gas Interests.

         Exhibit "B-1" --                  Plat of South Callaghan Ranch Lands.

         Exhibits "B-2 - B-24" --          Plats of Program Wells.

         Exhibit "C-1" --                  Term Assignment of Oil and Gas
                                           Leases.

         Exhibit "C-2" --                  South Callaghan Ranch Lease.

         Exhibit "C-3" --                  Excluded Wells.

         Exhibit "D" --                    JOA.

         Exhibit "E" --                    Production Headers and Applicable
                                           Wells.
                
         Exhibit "F" --                    VPP Pipeline Delivery Points.

         For additional consideration described and defined below, Mobil agrees
to (i) assign to Michael a term leasehold interest in the "McElroy Leases" and
the "GBGL&C Lease" as defined and described in attached Exhibit "A," and (ii)
grant all of Mobil's right, title and interest in, to and under or derived from
the lands described as "Oil and Gas Interests" in Exhibit "A" attached hereto.
This Agreement covers the lands depicted on the plat attached hereto as Exhibit
"B-1" (the "South Callaghan Ranch Lands"), INSOFAR AND ONLY INSOFAR as the
South Callaghan Ranch Lands cover the interval from the surface of the ground
down to 100 feet below the stratigraphic equivalent of the base of the Lobo 6
Sand, which is seen at a measured depth of 8,775 feet on the electric log run
in the South Callaghan Ranch Well #164 (API 4247936793) located in the
Margarito Herrera Survey 1192, A-2293, Webb County, Texas.  This grant shall be
pursuant to an oil and gas lease from Mobil to Michael and substantially in the
form of the lease attached hereto as Exhibit "C-2" (the "South Callaghan Ranch
Lease") and this assignment shall be pursuant to the Term Assignment form
attached hereto as Exhibit "C-1."

         The South Callaghan Ranch Lease shall have a primary term of seven (7)
years, shall be effective January 1, 1998, and shall cover only Mobil's
"undeveloped acreage" in the South Callaghan Ranch Lands with an express
provision that no well drilled under such lease shall have
<PAGE>   2
a bottom-hole location closer than 1,200 feet from any existing producing well
thereon (except this distance shall be 1,250 feet for the "Program Wells"
defined below) unless mutually agreed otherwise between the parties.  For
purposes of this Agreement, undeveloped acreage shall include all of the South
Callaghan Ranch Lands, SAVE AND EXCEPT the wells listed on Exhibit "C-3"
attached hereto (the "Excluded Wells") and the drilling units allocated to the
23 wells (the "Program Wells") drilled or proposed by Mobil under its 1997
Mobil Development Fund Program.  Each such Program drilling unit contains 40
acres, and each is designated with its applicable Program Well on the plats
attached hereto as Exhibits "B-2" through "B-24."

         If any currently producing well, including any Program Well, should
cease producing and become a plugging candidate under the JOA (described
below), then upon the parties' consent to plug such well, the 1,200 foot
restriction shall no longer apply to that well.  Furthermore, if any proposed
Program Well is not actually drilled as of the date of this Agreement, then the
1,200 foot restriction shall not apply to that well.  Michael and Mobil further
agree not to seek an exception to the density provisions as provided in Rule 38
WELL DENSITIES of the Statewide Rules for Oil, Gas and Geothermal Operations of
the Railroad Commission of Texas and not to seek changes to current field rules
or seek new field rules, without prior written agreement between the parties.

         Michael and Mobil shall execute a new joint operating agreement
substantially in the form attached hereto as Exhibit "D" (the "JOA") covering
the South Callaghan Ranch Lands to replace a portion of the Contract Area
covered by the current August 16, 1979 operating agreement.  The JOA shall
reflect pertinent changes regarding the parties and address among other
matters, the interests of the parties, the COPAS Accounting Procedure and the
gas balancing agreement.  Upon closing, Mobil shall resign as operator (i)
effective May 1, 1998 with respect to the undeveloped acreage in the South
Callaghan Ranch Lands, and (ii) as soon as reasonably possible with respect to
currently producing wells located on the balance of the South Callaghan Ranch
Lands.  Upon such resignations, Michael shall be appointed operator of the
South Callaghan Ranch Lands.  In order to insure an orderly change in operator
of the currently producing wells, Michael and Mobil anticipate a transition
period of up to, but not more than, one hundred twenty (120) days during which
Mobil will provide the agreed-upon transition services set forth in Exhibit "G"
of the JOA.  Upon completion of the transition period, Michael, as successor
operator, will be responsible for assuming all accounting, administrative and
regulatory services currently provided by Mobil.  Michael agrees that as
successor Operator under the JOA, it shall be subject to a currently existing
agreement with Maverick Engineering, Inc. regarding production operations,
production facilities, production engineering services and production
compression.

         Michael shall operate the South Callaghan Ranch Lands as a reasonable
and prudent operator acting in a lawful, safe, efficient and cost effective
manner at all times.  As Operator, Michael agrees that it shall, for the
benefit of the joint account under the JOA, render and make timely payment of
all (i) royalties and other payments out of production under the terms of
leases comprising the Contract Area, and (ii) severance, production, and ad
valorem taxes assessed against the Contract Area in the JOA.  Michael shall
keep the South Callaghan Ranch Lands free from all liens, encumbrances, claims
and causes of action except for (i) liens for taxes or assessments not yet due
or not yet delinquent, and (ii) unperfected existing inchoate claims which may,
by subsequent action


                                      2
<PAGE>   3
of the claimants or operation of law, attach to the South Callaghan Ranch
Lands.  Michael shall provide to Mobil its quarterly financial statements and
such other information as Mobil may reasonably request regarding Michael's
operating practices and business condition.  Michael shall employ or contract
with those engineering and field operations personnel who are capable and
experienced in the drilling, completing, reworking, producing and operating of
high pressure gas wells.  The JOA shall provide for the removal of Michael as
Operator for good cause, which shall include gross negligence, willful
misconduct, the material breach of, or inability to meet, the standards of
operation, and the material failure or inability to perform its obligations
under the terms and provisions of the JOA.  Such terms, provisions and
obligations under the JOA shall include, but are not limited to, the timely
delivery of the VPP and maintaining appropriate flowline pressures.  The COPAS
Accounting Procedure attached to the JOA as Exhibit "C" shall enable Michael to
charge Mobil for its proportionate share of costs as set out therein.

         In operating and producing the South Callaghan Ranch Lands, Michael
agrees to conduct operations in a manner such that pressures on existing
flowlines immediately upstream of the flowline block valves on the Production
Headers do not increase by more than 5% above the pressure at which they were
operating as of the Closing.  If Michael wishes to increase pressures on an
existing flowline by more than 5%, Michael shall obtain written permission from
Mobil, prior to effecting an increase.  No permission shall be required if the
pressure increase is a result of a successful wellwork project on the well
originally serviced by the flowline.  "Production Headers" are those headers
referred to as  Header A through Header RR on Drawing Nos. D-960089-0201-0000
through D-960089-0201-0015, depicted on Exhibit "E" attached hereto (legible,
large scale versions of which drawings were furnished to, and are in the
possession of, Michael).

         As additional consideration for the agreements contained herein,
Michael shall guarantee the delivery of a volumetric production payment (the
"VPP") equal to 4.0 BCF of natural gas, free of all cost and expense (net of
royalty, production and severance taxes, post-production charges and the like),
delivered into one (1) or more of either (i) Katy Plant Tailgate pipelines
listed on attached Exhibit "F", (ii) Mobil LaGloria tailgate, or (iii) Agua
Dulce pipelines listed on attached Exhibit "F", in such volumes at each as
Michael shall reasonably determine.  Michael shall timely notify Mobil (by
telephone, confirmed in writing or by electronic communication) of the volumes
Michael will make available to Mobil at each of the three (3) points for each
month no later than three (3) working days prior to the last day of the
preceding month.  Once Michael has notified Mobil of the volumes available at
each of the three (3) points, Michael shall not change the volume it makes
available at any of the three (3) points during that month without Mobil's
prior consent.  Contemporaneously with the confirmation by Michael of the
delivery point(s) for a particular month, Mobil or its agent or designee shall
have the right to nominate the specific Exhibit "F" pipeline(s) for actual
delivery purposes.  Michael will use its best efforts to honor Mobil's pipeline
nomination.

         The VPP shall be delivered out of Michael's then-current Webb and
Zapata Counties production base in a volume stream of an average of 16.35 MMCF
per day (491MMCF per month) beginning on May 1, 1998 and continuing until
December 31, 1998 until the entire 4.0 BCF VPP





                                       3
<PAGE>   4
has been delivered to Mobil.  The parties, recognize that, as a practical
matter, pipeline imbalances may cause the actual volumes to be delivered to
vary; such variance shall not constitute a default in the payment of the VPP.
The parties agree to use their best efforts to remedy any such variances in
delivered volumes by the end of the month following the month during which the
variance in delivery actually occurred.  Failure by Michael to deliver the VPP
shall result in the ipso facto termination of the South Callaghan Ranch Lease;
provided, however and in that event, Michael shall be entitled to own only 40
acres around each then producing or currently drilling well located on the
South Callaghan Ranch Lands as governed by the South Callaghan Ranch Lease.
Failure by Michael to timely deliver the VPP over the course of such period
shall result automatically in (i) Mobil becoming the operator of the wells
existing as of the date of this agreement and (ii) the termination of the JOA
as to all of the Contract Area not otherwise retained by Michael.  Michael and
Mobil agree that the VPP is excluded from any and all South Callaghan Ranch
Lease gas balancing calculations and agreements.

         With respect to the VPP, Michael's delivery of such gas shall be
subject to the following quality specs:

         All gas delivered by Michael shall meet the quality and heat content
         of the receiving transporter.  The unit of quality measurement for
         purposes of this agreement shall be one MMBtu dry.  Measurement of gas
         quantities hereunder shall be in accordance with the established
         procedures of the receiving transporter.

         Closing of the transactions contemplated hereby shall occur on or
before April 23, 1998, at such time and place as Mobil and Michael shall
mutually agree.

         In addition to the above specific matters, the parties do generally
agree as follows:

         1.      The parties do not intend to create, nor shall this Agreement
be construed to create, a partnership, mining partnership, joint venture, or
other relationship of mutual agency between the parties, their relation with
respect to this Agreement and all rights, interests, and obligations hereunder
being solely one of lessor and lessee.  Nothing herein shall be construed as
authorization of one party hereto to act as general agent for the other party
nor to permit either party to act for or on behalf of the other party outside
the terms of the Agreement.

         2.      Michael may not transfer or assign its operational duties and
responsibilities hereunder without first obtaining the written consent of
Mobil, which consent shall not be unreasonably withheld.  Except as otherwise
expressly provided in this Agreement, Mobil's rights under this Agreement shall
be freely assignable. Notwithstanding anything herein to the contrary, no
assignment by either party shall operate to relieve the transferring party from
direct responsibility and liability to the other party hereto for the
performance of all of the transferring party's obligations hereunder.

         3.      Time is of the essence in each and every provision of this
Agreement.





                                       4
<PAGE>   5
         4.      This Agreement is solely for the benefit of the parties hereto
and their respective successors and assigns. There are no intended third-party
beneficiaries of this Agreement.

         5.      The parties hereto agree to execute, acknowledge, and deliver,
as appropriate, such other and further instruments, documents, and assurances
as the other of them may reasonably require to effectuate the purpose and
intent of this Agreement.

         6.      Any failure by Michael, on the one hand, or Mobil, on the
other hand, to comply with any obligation, covenant, agreement or condition
contained herein may be expressly waived in writing by the other party;
provided, however, any such waiver or failure to insist upon strict compliance
shall not operate as a waiver of, or estoppel with respect to, any subsequent
or other failure.

         7.      All notices, requests, demands, and other communications
required or permitted hereunder shall be in writing and shall be deemed to have
been duly given if delivered by hand (including, without limitation, by
overnight courier), transmitted by facsimile, or mailed, certified or
registered mail (return receipt requested) with postage prepaid to the
applicable party as follows:

                                OIL AND GAS LEASE


THE STATE OF TEXAS     )        
                       )
COUNTY OF WEBB         )   

This agreement made effective this, the first day of January, 1998, between
Mobil Producing Texas & New Mexico Inc., herein called "Lessor", whose address
is 12450 Greenspoint Drive, Houston, Texas 77060-1991 and Michael Petroleum
Corporation, as "Lessee", whose address is 13101 Northwest Freeway, Suite 320,
Houston, Texas 77040.

                                  WITNESSETH:

         DEFINITIONS: The parties hereto agree that for purposes of this lease,
the following definitions shall be applicable:

         a. "Oil and/or gas" is defined as oil, gas, casinghead gas, other
         gaseous substances and associated hydrocarbons in either a liquid or
         gaseous phase or state and such minerals as may be produced in
         association with the production of oil, gas, casinghead gas, other
         gaseous substances and associated hydrocarbons; provided, however, that
         nothing in this Lease shall be deemed to authorize the gas gasification
         or in situ combustion of coal or lignite, and this Lease shall not be
         deemed to cover either coal or lignite. The classification of a well as
         either a gas well or oil well by the Railroad Commission of Texas shall
         be conclusive in respect of its classification under the terms of this
         Lease.

         b. "Operations for drilling", "drilling operations", "commencement of
         operations", "commence drilling operations", "commences drilling
         operations", "commencement of a well" and "actual drilling operations"
         shall have the same meaning being (i) the actual entry of the drillbit
         of a drilling rig, capable of achieving the total depth permitted and
         approved by the Railroad Commission of Texas, into the soil of leased
         premises and the timely prosecution of such actual drilling operations
         with reasonable diligence to the completion of same as a dry hole or
         commercial well, or (ii) the actual reentry into an existing wellbore
         with a drilling or workover rig capable of re-entering such well for
         the purpose of completing or recompleting such well in previously
         uncompleted and unproduced zones and the timely prosecution of such
         actual re-entry operations, with reasonable diligence, toward the
         completion of such previously uncompleted and unproduced zone or zones
         encountered in such wellbore as either producing or dry zones.

         c. "Operations for reworking", "reworking operations", "commencement of
         reworking operations", "commence reworkinq operations" and "actual
         reworking operations" shall have the same meaning, being the actual
         re-entry into an existing wellbore with a drilling or workover rig
         capable of reentering and reworking such well and the timely
         prosecution of such actual reworking operations with reasonable
         diligence toward the re-establishment or enhancement of production of
         commercial oil or gas from such previously producing zone or zones.

         d. "Operations" shall be defined as all other lease operations which
         may be conducted by Lessee under this lease except those defined in b
         and c above. "Operations" as defined in this subparagraph d shall
         never be the basis for perpetuation of this lease.


<PAGE>   2
         e. "Completed", or "completion" shall have the same meaning and the
         date a well is completed shall be on (i) the date of the potential
         test conducted for Railroad Commission purposes; (ii) sixty (60)
         days after the drilling rig is released from such well; or (iii)
         the date a well is abandoned as a dry hole, whichever happens sooner.

         f. A well shall be considered and defined as "shut-in" on the earlier
         of the following dates: (1) the date of the potential test conducted
         for Railroad Commission purposes; (2) sixty (60) days after the
         drilling rig is released; or (3) the day that gas ceases to be sold
         from a gas well capable of producing in paying quantities.

         g. "Excluded Wells" shall be those South Callaghan Ranch Wells listed
         on Exhibit "B" attached hereto.

         1. GRANTING CLAUSE: LESSOR, in consideration (i) of Ten Dollars 
($10.00) in hand paid, (ii) of the agreements of Lessee herein contained, and
(iii) of the forbearance by Lessee from drilling any well with a bottom-hole
location closer than 1,200 feet from any Excluded Well (except with respect to
Program Wells, this distance shall be 1,250 feet) without mutual agreement from
Lessor, hereby GRANTS, LEASES and LETS exclusively unto Lessee, for the purpose
of investigating, exploring, prospecting, and drilling for and producing oil,
gas and all other hydrocarbons and sulphur necessarily produced with such oil
and gas, conducting exploration, geologic and geophysical surveys by
seismograph, core test and magnetic methods, injecting and re-injecting gas,
fresh water and other fluids and air into subsurface strata for secondary or
tertiary recovery purposes only, laying, maintaining and replacing pipelines,
building roads, tanks, power stations, telephone lines and other structures
thereon and to produce, save, take care of, treat, transport and own said
products, the following described land situated in Webb County, Texas, to wit:

         2. PROPERTY DESCRIPTION: See attached Exhibit "A".

         For the purpose of determining the amount of any payments hereunder,
said land shall be deemed to contain 38,176.56 acres, whether actually
containing more or less.

         3. RESERVATIONS: There is EXCEPTED from this lease and Lessor RESERVES
unto himself, his heirs, successors, administrators and assigns:
<PAGE>   3

            (a) all minerals except oil, gas and all other liquid, solid and
gaseous hydrocarbons and sulphur that is necessarily produced with such oil or
gas;

            (b) equal and concurrent rights of occupancy, use and possession of
the surface estate by Lessor, surface owners or Lessor's or surface owner's
other mineral, surface, grazing and recreational lessees or assignees, together
with the right of ingress to and egress from the above described lands and other
lands owned by Lessor for the purpose of exploring (including the granting of
geophysical and seismic permits), developing and operating said lands for oil,
gas and other minerals of whatever nature which may hereafter be released from
this lease, and equal and concurrent rights to complete water source wells on
the leased premises and in any reservoir not productive of oil or gas for the
purposes of obtaining water for the exploration, development and operation of
Lessor's reserved rights, subject to the provisions of paragraph 15.(n) and 18.
Further, Lessor or surface owner reserves surface use for grazing, farming and
recreational lessees, which surface use rights shall be concurrent with the
surface rights herein granted to Lessee.

            (c) All depths below 100' beneath the stratigraphic equivalent of
the base of the Lobo 6 Sand, which is seen at a measured depth of 8,775 feet on
the electric log run in the South Callaghan Ranch # 1 64 Well (API 4247936793),
in Margarito Heffera Survey II 92, Abstract 2293,

            (d) All wells currently existing on the leased premises, including
but not limited to the Excluded Wells.

         4. HABENDUM CLAUSE: Subject to the other provisions herein contained,
this lease shall be for a term of seven (7) years from January 1, 1998 (called
"Primary Term") and as long thereafter as oil, gas or other leased substance is
produced from said land in paying quantities or as long as this lease is
continued in effect as otherwise provided herein.

         5. ROYALTIES: Lessor is not retaining or reserving any royalties or
royalty interests under the terms of this Lease and no royalties are payable to
Lessor under the terms of this Lease. However, Lessor and Lessee recognize and
acknowledge that there are certain outstanding perpetual non-participating
royalty interests of record as of the effective date of this Lease burdening
Lessor's mineral estate leased hereunder (the "NPRI Interests") and that Lessee
is acquiring the leasehold estate granted hereunder subject to and burdened by
the NPRI Interests. Lessee shall, as of the effective date of his Lease, assume
and be responsible for the payment of the NPRI Interests in accordance with the
terms of the instruments creating such
<PAGE>   4
interests and shall defend, indemnify and hold Lessor harmless from and against
any and all claims arising out of or relating to the payment of royalties to
the holders of the NPRI Interests insofar as they relate to periods of time
from and after the effective date of this Lease.

         6. SHUT-IN ROYALTY CLAUSE: (a) If after the expiration of the primary
term there is a gas well on this lease capable of producing gas in paying
quantities and classified as a gas well by the Railroad Commission of the State
of Texas, but gas is not being sold for ninety (90) consecutive days, Lessee may
pay or tender as royalty, to the owner or owners of the NPRI Interests, on or
before ninety (90) days after the date on which said well is shut in, or the
lease ceases to be otherwise maintained, (whichever date Lessee elects to
utilize) and thereafter at annual intervals, a sum equal to the amount of FIVE
AND NO/100 ($5.00) DOLLARS per acre for each such net acre then subject to the
shut-in provisions of this lease at the time such payment is made; and if such
payment is made or tendered, this lease shall not terminate but this lease shall
continue and it will be considered that gas is being produced from this lease in
paying quantities, for a twelve (12) month period commencing from date such
payment is made whether or not sporadic production occurs during such twelve
(12) month period. Each subsequent shut-in payment shall be in like amounts of
FIVE AND NO/100 ($5.00) DOLLARS per acre for each such net acre then subject to
the shut-in provisions of this lease and payable on or before the annual
anniversary date the first payment is made; and, upon each timely and proper
payment, this lease shall not terminate for twelve (12) months (each payment
shall be due by and each annual shut-in royalty period shall commence from the
date established as the first payment date, and subsequent 12-month payments
shall be payable on or before the same day of the twelfth month following the
month of the prior payment); however, if a well capable of producing gas in
commercial or paying quantities is completed during the primary term of this
lease, then Lessee may, at its election, pay or tender the first or initial
shut-in royalty payment within ninety (90) days after such well is shut-in or on
or before the next ensuing anniversary date of this lease whichever happens
later.

            (b) This lease may not be continued in force and effect by the
payment of shut-in gas royalty alone for more than a period of two (2) years
after the expiration of the primary term; however, in the event that, after such
two (2) year period and after the actual production and marketing of the gas has
once been obtained, the Lessee is thereafter required to shut in said well(s)
due to its inability to (1) obtain a reasonable market for the gas, or (2) where
its purchaser of gas is unwilling or unable to purchase and take such gas from
no fault of Lessee, the Lessee may pay or tender to the owners of the NPRI
Interests, as royalty, on or before ninety (90) days after the date on which
said well(s) is shut in, a sum equal to FIVE AND NO/100 ($5.00) DOLLARS per acre
of land for each such net acre then subject to the shut-in provisions of this
lease, and it will be considered that gas is being produced from this lease in
paying quantities for a period of twelve (12) months. 

            (c) In the event Lessee tenders a timely and proper shut-in royalty
payment, no additional shut-in royalty payments shall be required to be made by
Lessee to the owners of the NPRI Interests during the twelve (12) month period
earned by such payment (if payment
<PAGE>   5
is tendered for periods covered up to two (2) years after the expiration of the
primary term) or the 12-month period earned by such payment (if made after two
(2) years after the expiration of the primary term when Lessee is unable to
obtain a gas contract or Lessee's purchaser is unwilling or unable to take gas,
as the case may be), in order to perpetuate this lease for such 12-month
shut-in period.

            (d) In the event Lessee utilizes paragraph 6 to continue this lease
in force and effect as to all or any portion of said lands by the payment of
shut-in royalty, Lessee shall, upon the written request of Lessor by certified
mail and at Lessee's cost and expense, conduct appropriate and adequate tests of
each shut-in gas well designated by Lessor in such request to determine whether
each such designated gas well is actually capable of producing gas in paying
quantities. Such tests shall be made at times selected by Lessee within thirty
(30) days after Lessee's receipt of Lessor's written request but not less than
thirty (30) days prior to the expiration of any annual period for which a
shut-in royalty payment has been made by Lessee on each particular well
designated by the Lessor, if notice is timely received. Lessee shall give Lessor
reasonable notice prior to conducting such well tests, and Lessor or Lessor's
duly appointed representative shall have the right to be present at the testing
of each well and shall be entitled to receive full information in connection
with such testing. In the event any such test discloses that such well is not
capable of producing gas in paying quantities, it shall be considered that such
well has ceased to produce gas in paying quantities on the last date of testing
of such well. Likewise, Lessor shall have the same privileges, and Lessee shall
have the same requirements, as above outlined to test any oil well on said
lands, and if such tests determine such oil well or wells are not producing or
capable of producing in paying quantities, then such well or wells shall be
considered as having ceased to produce oil in paying quantities as of the date
of such test. Furthermore, if it is considered that any well is not capable of
producing oil and/or gas in paying quantities after such tests, Lessee shall
nevertheless have the opportunity to work-over or recomplete such well or
commence actual drilling operations on a new well within ninety (90) days after
it has been tested as non-commercial in accordance with paragraph 9 below.

         7. LESSEE'S USE OF WATER/MINERALS: Subject to the provisions of
paragraphs 15(n) and 18, Lessee shall have use of oil, gas and non-potable water
from said lands except water from surface owner's tanks and wells, for all
operations hereunder. However, Lessee's use of such water shall be limited to
primary drilling operations only on the leased premises and may not be used for
water flooding, secondary or tertiary operations. No royalty shall be owed on
oil or gas used by Lessee for operations on the leased premises.
<PAGE>   6
         Notwithstanding the above, Lessee may recycle gas for gas lift purposes
or for injection into any oil or gas producing formation underlying the leased
premises, and no royalties shall be payable on the gas so recycled until such
time as the same may thereafter be produced and sold or used by Lessee in such
manner as to entitle the royalty owners to a royalty under the provisions of
this lease.

         Lessee shall not have the use of fresh water or surface owner's surface
waters without written consent and agreed compensation, and nothing herein shall
be construed to limit the application of paragraphs 15(n) or 18. Lessee shall
have the free use of fresh water from water wells drilled by Lessee as herein
provided for drilling purposes only. Lessee shall not have the right to dispose
of salt or waste water produced or obtained from off of the leased premises.
Lessee shall have the privilege of injecting salt water produced or obtained
from the leased premises back into subsurface strata, conditioned upon such
reinjection not contaminating or contacting fresh water bearing sands and so
long as such reinjection does not damage the production of water or gas and oil
reservoirs or strata payments or conduct drilling or reworking operations in
order to perpetuate this lease to the end of the primary term. Further,
irrespective of whether drilling operations, reworking operations and/or actual
production has commenced and/or ceased during the primary term, this lease shall
be perpetuated to the end of the primary term.

         8. PAID UP LEASE: This lease is a "Paid Up Lease" meaning that delay
rentals ordinarily required to be paid to perpetuate a lease from year to year
in lieu of drilling operations have been paid in advance. Therefore, Lessee
shall not be required to make any annual delay rental payments or conduct
drilling or reworking operations in order to perpetuate this lease to the end of
the primary term. Further, irrespective of whether drilling operations,
reworking operations and/or actual production has commenced and/or ceased during
the primary term, this lease shall be perpetuated to the end of the primary
term.

         9. DRILLING. CONTINUOUS DEVELOPMENT AND CESSATION OF PRODUCTION
CLAUSES:

            (a) DRILLING AND CONTINUOUS DEVELOPMENT OPERATIONS: If, at the
expiration of the primary term, oil and/or gas is not being produced from said
land, but Lessee is then engaged in actual drilling operations thereon, this
lease shall remain in force as long as such actual drilling operations are
prosecuted with no cessation of more than one hundred twenty (120) consecutive
days until completion of such operations and if they result in production of oil
and/or gas and subject to the provisions of Paragraph 10 below, so long
thereafter as oil or gas or either of them is produced from said land in paying
or commercial quantities. If this lease is extended beyond the primary term by
virtue of production or actual drilling operations, then Lessee agrees to
commence a continuous development program without allowing a period of more than
120 days to elapse between the completion of one well and the commencement of
actual drilling operations on the next succeeding well. Commencement of
operations on the first such continuous development well shall occur not later
than 120 days after the end of the primary term, or 10 days after the completion
of a well which is being drilled at the end of the primary term, whichever is
the later date and this lease shall continue in full force and effect during
such continuous development program. Upon cessation of such continuous
development program, this lease shall terminate (either in whole or in part) as
provided in paragraph 10 hereinbelow. The sole liability or penalty, if any, for
the failure of Lessee to drill or complete any well or wells required or
permitted hereunder shall be termination (either in whole or in part) of this
lease as more fully described in paragraph 10 below.
<PAGE>   7
            (b) CESSATION OF PRODUCTION: If, within ninety (90) days prior to
the expiration of the primary term or at any time thereafter and after discovery
of oil and/or gas, production of oil and/or gas should cease from any cause,
this lease shall not terminate if (i) Lessee commences actual drilling
operations within ninety (90) days thereafter and continuously conducts actual
drilling operations without cessation thereof for more than ninety (90) days and
such actual drilling operations result in production of oil and/or gas, so long
thereafter as oil, gas or either of them is produced from said land in paying or
commercial quantities; or (ii) within such ninety (90) day period after
cessation, Lessee commences actual reworking operations, as opposed to drilling
operations as defined in DEFINITIONS above and so long as Lessee continuously
conducts such actual reworking operations on such well or wells without
cessation of more than ninety (90) days and such actual reworking operations on
such well result in re-establishment of production in paying quantities. If such
actual reworking operations do not result in re-establishing production, Lessee
shall have ninety (90) days after the termination of such reworking operations
within which to commence the drilling of a new well, or recompleting in a
previously uncompleted or unproduced zone, or further reworking operations in a
previously producing zone.

            (c) DILIGENT, GOOD FAITH OPERATIONS: Each well drilled under this
lease shall be drilled with reasonable diligence and in good faith and in a good
and workmanlike manner in a bona fide attempt to produce oil or gas therefrom.

         10. RELEASE CLAUSE: At the expiration of the primary term, or upon
cessation of the continuous development program, if applicable, this lease shall
ipso facto terminate as to all lands covered hereby, SAVE AND EXCEPT one hundred
sixty (160) acres surrounding each oil and gas covered lease shall continue in
force and effect as to the proration unit surrounding each well required to
obtain such full allowable. Lessee shall, within thirty (30) days after the
expiration of this lease or parts hereof, file of record in the office of the
County Clerk of Webb County, Texas, an instrument releasing this lease insofar
as said lease has terminated, specifically describing by metes and bounds or
other proper legal description the retained unit for each producing well and the
depth which may be retained by Lessee thereunder. In the event Lessee shall fail
to either designate a unit or units or fail to release acreage and/or horizons
of record within sixty (60) days after the expiration of this lease by Lessee
filing such designation or release in the Office of the County Clerk of Webb
County, Texas, then Lessors shall notify the Lessee of its failure and if within
thirty (30) days of the date of such written notice by certified mail to Lessee,
Lessee does not designate unit or units or release the acreage or horizons by
filing a proper instrument in the Office of the County Clerk of Webb County,
Texas, then Lessor shall make the designation of unit or units or release of
acreage and/or horizons by filing the instrument designating the unit or units
or release of acreage and/or horizons in the Office of the County Clerk of Webb
County, Texas, and such designation and/or release by Lessors shall be binding
upon the Lessees.
<PAGE>   8
         At such time as a partial termination of this lease occurs under the
provisions of this paragraph, each such retained unit as to which said lease has
not terminated shall be considered as a separately leased tract, in the same
manner as if Lessor had executed separate and distinct leases covering each such
retained unit. Lessee shall not be obligated to protect against drainage, if
any, between and among "separately leased tracts". Notwithstanding a partial
termination of this lease under the above provisions, it is agreed that Lessee
shall have and retain such easements of ingress and egress over those lands
originally covered hereby as shall be necessary to enable Lessee to develop and
operate the portion or portions of this lease then in effect for the production
of oil or gas therefrom; and, it is further agreed that it shall not be
necessary for Lessee to remove or relocate any pipelines, tank batteries or
other surface equipment or installations from any portions of this lease which
have terminated for so long as same continue to be used for the development of
and operations on such portions of this lease as continued in force and effect.

         The drilling of wells in accordance with spacing provisions of
Paragraph 10 shall not be construed as an agreement or consent on the part of
Lessor that such drilling constitutes reasonable development of the leased
premises, but Lessee agrees to drill all such additional well or wells on the
leased premises, or such portion or portions thereof as may be in force and
effect from time to time, as would a reasonably prudent operator under the same
or similar circumstances in order to reasonably develop the same for the
production of oil and/or gas.

         11. OFFSET CLAUSE: If any well or wells producing oil or gas in paying
quantities should be brought in on adjacent land and draining a portion of the
leased premises to which this lease is then in force and effect, Lessee agrees
within a reasonably prudent time after such offset well commences actual
production to drill such offset well or wells as a reasonably prudent operator
would drill under the same or similar circumstances, or to rework or recomplete
a well on that portion of the leased premises being drained, in a zone or
horizon being the stratigraphic equivalent of that zone or horizon producing in
such offset well. In lieu of drilling, reworking or recompleting an offset well,
Lessee shall have the option of releasing this lease as to an eighty acre tract
of land adjacent to such draining well.

         12. ASSIGNMENT CLAUSE: The rights of Lessor may be assigned in whole or
in part but no change or division of ownership of the land, or royalties,
however accomplished, shall operate to enlarge the obligations or diminish the
rights of Lessee; and no change or division in such ownership shall be binding
on Lessee until thirty (30) days after Lessee shall have been furnished by
certified U.S. mail at the address specified herein, with a certified or
photocopy of the recorded instrument or instruments evidencing same. The rights
of Lessee may not be assigned in whole or in part without the prior written
consent of Lessor, which consent shall not be unreasonably withheld only if
Lessee can demonstrate that its proposed assignee possesses (i) a proven
ability to operate the kind of wells located on the South Callaghan Ranch Lands
and (ii) a level of financial responsibility and corporate capitalization
substantially similar to that of Lessee.

         All requests by Lessee for consent to assign must be in writing. Any
request for consent for a proposed assignment must be objected to in writing by
Lessor within thirty (30) days after receipt of such written request, failing in
which such request shall be deemed to be approved. No assignment of an
<PAGE>   9
interest in this Lease shall be effective until a recorded copy of such
assignment has been received by Lessor.  Notwithstanding anything herein to the
contrary, no assignment by either party shall operate to relieve the
transferring from direct responsibility and liability to the other party hereto
for the performance of all of the transferring party's obligations hereunder.
In the event of the death of any person entitled to royalties or other payments
hereunder, Lessee shall suspend such royalties or other payments until such
time as Lessee is furnished with proper evidence of the appointment and
qualification of an executor or administrator of the estate or if there be
none, then until Lessee is furnished with evidence satisfactory to it as to the
heirs or devisees of the deceased or the successors in interest to such
deceased owner and that all debts of the estate have been paid.

         13. FORCE MAJEURE CLAUSE: Should Lessee be prevented from complying
with any express or implied covenant of this lease, from conducting drilling or
reworking operations thereon or from producing oil or gas therefrom by reason of
or by operation of force majeure, any federal or state law or any order, rule or
regulation of governmental authority, then while so prevented, Lessee's
obligations to comply with such covenants shall be suspended and Lessee shall
not be liable in damages for failure to comply therewith and this lease shall be
extended while and so long as Lessee is prevented by any such cause from
conducting drilling or reworking operations on or from producing oil and gas
from the leased premises, and the time while Lessee is so prevented shall not be
counted against Lessee, anything in this lease to the contrary notwithstanding.
In the event Lessee intends to claim any rights under this paragraph, Lessee
shall advise Lessor or Lessor's Agent in writing within a period of thirty (30)
days after the date Lessee claims any obligation hereunder is suspended, setting
forth in reasonable detail such facts as Lessee relies upon to make the
provisions of this paragraph applicable. Notwithstanding anything above stated
to the contrary, if Lessee is prevented from complying with this lease or
resorts to force majeure because of Lessee's intentional acts or omissions, then
this provision shall not be available to Lessee to perpetuate this lease or
suspend Lessee's obligations. This provision shall not suspend nor delay the
time for the payment of royalties, shut-in gas royalties, or any other monetary
payments due and payable to Lessor under the Lease.

         14. WELL/DRILLING INFORMATION CLAUSE: If requested by Lessor in
writing, Lessee agrees to give Lessor and affected surface owners written
notice, prior to the commencement of any operations which are critical to the
enforcement of the terms and provisions of this lease. Said notice(s) shall
advise Lessor and the affected surface owner of the approximate date that
commencement of operations is intended and the approximate location of the same
and the objective depths of any proposed well, such notice to be given within a
reasonable time prior to the commencement of such operations. Lessor shall have
the optional right to either (i) request Lessee to furnish Lessor at the address
provided herein promptly upon Lessor's written request, free of charge, copies,
or (ii) have reasonable access during regular business hours to Lessee's records
and all information concerning the drilling, deepening, plugging back, coring,
testing and completing or recompleting of any and all wells, including the
driller's log, all electrical logs, and surveys, production charts and records
and information concerning the production and marketing of oil and gas from said
lands, with copies of all forms filed with the Railroad Commission of Texas or
any other governmental authority having jurisdiction over Lessee's operations
and pertaining to Lessee's operations under this lease; and, including seismic
data only as to shot point maps and reproducible film copies of seismic data
shot by Lessee over the lands covered in this lease with a half-mile flare, if
available, provided Lessor agrees to keep confidential all information acquired
by it under the terms of this paragraph. The confidentiality agreement shall not
apply to (a) any information of


<PAGE>   10
         15. SURFACE/SUBSURFACE PROTECTION CLAUSES: As a part of the 
consideration for this lease:

             (a) Prior to commencing any operations under this lease, when
acting as operator of the leased premises, Lessee shall consult surface owner
and provide information as to the form of operations, the proposed date of
commencement and the location of said operations.

             (b) Lessee agrees to use existing gates and roadways to enter and
leave the premises, where available.

             (c) Lessee and all persons entering or leaving said lands in
connection with Lessee's operations hereunder shall keep all outside and
interior gates along the route or routes designated for such use securely closed
except immediately before and immediately after each such separate use. Lessee
agrees that it will promptly repair any gate, fence or other improvement that
may suffer damage or injury by reason of Lessee's operations hereunder. Lessee
may, during the term of this lease place separate locks on any perimeter access
gate. If Lessee leaves a perimeter gate open during drilling or reworking
operations, surface owner may, at his option, require Lessee to place a guard at
the entrance to the leased premises during drilling and completion operations.

             (d) When acting as operator of the leased premises, Lessee will
maintain approaches, gates, cattle guards and roadways designated and used in
connection with its operations in a good state of repair and will promptly cause
to be repaired and restored any damage thereto occasioned by or resulting from
Lessee's operations. In regard to maintenance of roads used by Lessee or its
employees, contractors and invitees, Lessee shall repair damaged or
deteriorating portions of roads within a reasonable time not to exceed thirty
(30) days after notice by surface owner of need for such repair. Materials used
to repair road damage shall be either caliche, gravel or other materials except
dirt fill. Lessee agrees to work with the surface owner to keep the roads used
by Lessee in continuous state of good repair.
<PAGE>   11
         In connection with any roads built by Lessee, Lessee agrees to consult
with the surface owner as to the location of such roads and will construct such
division terraces as may be reasonably necessary to reduce soil erosion. Lessee
shall be required to install cattle guards or, at surface owner's option, pipe
gates to the side of such cattle guards at each fence crossing.

             (e) Each drill site on said lands, including slush pits, tanks,
separators, treaters and any and all other pertinent well and lease equipment
above the surface, will be enclosed and kept enclosed with a wire mesh or
bullwire fence capable of turning livestock, promptly after completion of any
drilling operations and such fence shall be maintained by Lessee for so long as
such equipment remains on leased premises or during the period of production
resulting from such operations. No drilling operations, pipeline constructed,
seismic lines or operations of any nature shall be conducted within 300 feet of
any houses, barns, water wells or permanent improvements, without surface 
owner's notice and consent.

             (f) Within ninety (90) days after completion or abandonment of any
well drilled on said lands, Lessee or its designated operator will clean up the
well site and remove from said lands any and all oil spills, junk materials,
pieces of iron, pipes, steel and other debris and foreign materials and will
level all mounds, fill all pits, and other excavations upon being notified by
Lessor and will remove all deleterious materials and substances that might cause
injury to person or livestock. Any such clean up shall be conducted in
compliance with all applicable rules and regulations of the State of Texas
Railroad Commission or other regulatory authority and any subsurface fresh water
stratum, but will be contained and dispose of same in keeping with applicable
governmental rules and regulations, including without limitation, Environmental
Laws, as hereinafter defined.

             (g) Lessee or its designated operator will use its best efforts to
prevent the escape of salt or other noxious waters and will not permit the same
to run into any surface water tank, water well, creek, ravine, or upon or over
the premises, not to penetrate, seep or flow or be injected into any subsurface
fresh water stratum, but will be contained and dispose of same in keeping with
applicable governmental rules and regulations, including without limitation,
Environmental Laws, as hereinafter defined.

             (h) Lessee or its designated operator will use its best efforts to
prevent fires on said lands and will use its best efforts to prevent papers,
boxes, sacks and containers and waste materials of any kind from coming on said
lands and littering the premises.

             (i) Prior to erecting any storage tanks, pipelines, compressor
stations or other usual lease facilities required by Lessee for producing oil
and gas and operating this lease,
<PAGE>   12

Lessee, when acting as operator, shall advise surface owner of Lessee's
intentions.  Surface owner and Lessee will then mutually select the site or
sites for locating such equipment and pipelines, taking into consideration the
operations of surface owner and Lessee's needs in conducting its operations
under the terms of this lease in a reasonable manner.

             (j) Lessee or its designated operator is prohibited from
constructing an oil or gas refinery or a plant for cleaning up gas and removing
H2S on the leased premises. The location of separators, dehydrators and
compressors shall not be considered as plants.

             (k) No employee, representative or contractor of Lessee or any
other person allowed to come upon said land by Lessee shall be permitted to
hunt, fish, swim, camp or picnic on said land, and no dog, gun, firearm, fishing
equipment or other sporting paraphernalia of this type will be permitted on the
premises. If any of Lessee's representatives or employees violate this
provisions, surface owner may give notice thereof to Lessee and, if Lessee does
not voluntarily remove or exclude any such party, surface owner shall have the
right to eject such party from said lands and thereafter prohibit such party
from entering upon said lands.

             (l) Except as otherwise provided for herein, Lessee shall have the
right, at any time within ninety (90) days after abandonment or cessation of
use, but not thereafter, to remove any property and fixtures placed on said
lands and if Lessee fails to remove such property and fixtures within said
ninety (90) days, such property and fixtures shall be deemed to have been
abandoned by Lessee, and Lessor may take possession thereof and dispose of the
same as Lessor sees fit; provided, however, Lessee shall not be relieved of its
liability to plug any well so abandoned. Lessee shall bury all pipelines a
minimum of thirty-six (36") inches or more beneath ground level unless surface
owner deems otherwise.

             (m) Lessee or its designated operator will restore the surface of
said lands used by Lessee or its agents, contractors and employees, to as near
its original condition as is reasonably practicable after the completion of each
operation conducted hereunder and root plow such areas and seed such areas with
4 to 6 pounds per acre of grass of surface owner's choice.

             (n) Each water well drilled on the leased premises by Lessee
together with all equipment in or on said well shall become the property of
surface owner upon the full release of this lease; provided, however, the
surface owner shall have the right to use water therefrom during the term of
this lease, so long as such use does not interfere with Lessee's operations.
<PAGE>   13
Provided, further, that if Lessor so elects, Lessee shall, at Lessee's sole
cost and expense, plug and abandon each water well which surface owner elects
not to take over.

             (o) Lessee or its designated operator agrees to pay to the surface
owner the actual damages, if any, resulting to the surface of said lands, ranch
roadways used and/or constructed by Lessee, fences, gates, cattle guards,
houses, barns, windmills, tanks and other structures, trees, grass, crops,
cattle and livestock caused by Lessee's operations or occasioned by reason of
such operations or such damages as surface owner may incur by reason of
Lessee's failure to comply with the terms of this lease.

              (p) If Lessee or its designated operator conducts seismic
operations or should Lessee lay gathering pipelines across the leased premises,
then Lessee shall be required to compensate the surface owner for damages based
on the prevailing rate being paid in the area at the time for pipeline 
right-of-way and/or seismic lines. Further, Lessee shall be obligated to pay
surface owner for each surface site, such as drillsites, separator, dehydrator
and compressor sites based on the usual going rate being paid for such surface
sites and usage in the area at the time. Nothing herein shall restrict Lessee's
right to lay gathering pipelines for transportation of lease gas or conduct
seismic operations on leased premises.

             (q) Lessee or its designated operator shall be required to
compensate surface owner for each new road based on the prevailing price being
paid for new roads in the area at the time of construction of same. Lessee shall
not be allowed more surface for roads and/or drillsites than is necessary,
taking into consideration the nature and depth of drilling contemplated. As to
any other actual damage to the surface, surface owner shall be compensated based
on the rate prevailing for similar damages in the area at the time.

             (r) Regarding drillsites, Lessee or its designated operator shall,
no later than twelve (12) months after completion of a well, fill all pits,
level all dumps, remove debris and restore the surface to substantially its
original condition including root plowing the area used and seeding same with 4
to 6 pounds per acre of grass of surface owner's choice.

             16. NOTICE CLAUSE. This lease and all of Lessee's operations
hereunder shall be in keeping with the standard of conduct of a reasonably
prudent operator and shall be done in good faith and in compliance with all
valid and applicable laws, rules and regulations, both Federal and State, and
any agency thereof. Lessee agrees to designate in writing, or give notice in
person to Lessor and surface owner, the name of the person or persons to be
present from time to time on said premises as current operations are being
conducted and with whom surface owner may handle directly any claim of injury
and damage to livestock, surface area or improvements on said premises as
current operations are being conducted. All notices required to be given under
the terms of this lease shall be given to the following persons who are
designated Lessor's,
<PAGE>   14
Lessee's and surface owner's respective agents for notice only:

                               TO SURFACE OWNERS:

                    (According to record title determination)

Any party hereto may from time to time designate in writing a different address
or agent for the giving of any notice hereunder.

         17. WARRANTY OF TITLE: Lessor warrants title to the property being
herein leased by, through and under Lessor but not otherwise.  It is agreed
that if a Lessor owns an interest in the oil, gas or leased substances on, in
or under said land less than the entire fee simple estate, then the royalties
and shut-in royalties to be paid to the owners of the NPRI Interests shall be
reduced in the proportion that said Lessor's interest bears to the whole and
undivided fee in accordance with the nature of the estate of which Lessor is
seized.

         18. CORRELATIVE AND CONCURRENT SURFACE RIGHTS: Lessor (as each Lessor's
interest may appear) and Lessee recognize (i) the rights herein granted to
Lessee to reasonable use and access over, across and upon the surface estate to
explore for, develop, store, market, transport and produce the leased minerals;
and (ii) the concurrent and correlative rights of the surface owner(s) to the
use, enjoyment and benefits of the surface estate that the Lessee, in exercising
the rights herein granted, is limited thereby to such use or usage as is
reasonably necessary and which is conducted with due regard for the rights of
the surface owners(s) and which does not unduly interfere with the surface
owner's use of surface.
<PAGE>   15
         In the event that surface owner desires to cultivate, subdivide, and/or
develop all or a portion of the surface estate subject to this lease, then in
such event, Lessee and surface owner agree to enter into such agreement or
agreements that will facilitate the intended cultivation, sale or development of
such tract to and by the surface owner, as the case may be, but which will also
allow Lessee reasonable access to and use of the surface to such surface tracts
to be sold, subdivided, developed or cultivated.

         19. FORFEITURE CLAUSE: In the event Lessor considers that obligations
of Lessee or implied covenants of this lease are not being complied with, Lessor
shall notify Lessee in writing by certified mail of the facts relied upon as
constituting a breach of any expressed or implied covenants or obligations of
Lessee hereunder and Lessee, if in default, shall have sixty (60) days after
receipt of such notice in which to commence compliance with its obligations
hereunder. If such breach is not timely cured and Lessor obtains a final
non-appealable judgment finding that Lessee has breached any covenant hereof,
expressed or implied, then it is agreed that Lessor shall be entitled to a
decree providing for cancellation or forfeiture of the lease in the event such
breach is not rectified or commenced in good faith to be rectified by Lessee
within sixty (60) days from the date such decree becomes final; provided,
however, that failure on the part of the Lessee to cure any alleged default of
any expressed or implied covenant of this lease shall not result in Lessee
forfeiting any producing oil or gas well or wells or shut-in gas well or wells
and acreage allocated thereto for production, not then subject to breach or
default. Failure of Lessee to (i) produce oil, gas or other leased substances in
paying or commercial quantities; (ii) to timely and properly pay shut-in
royalties; (iii) to timely commence drilling or reworking operations as provided
in provisions of this lease, and/or (iv) failure to pay royalty in accordance
with Paragraph 50) above, and other special limitations shall not constitute an
obligation for purposes of this paragraph, as failure of Lessee to timely
comply with such provisions shall result in termination of this lease.

         20. ABSTRACTS: Any abstracts in Lessor's possession or control shall,
upon written request of Lessee or its assignee, be delivered to Lessee or its
assignee for examination; but Lessee or its assignee shall be liable for the
safekeeping and return of same. If Lessee or its assignee shall obtain an
abstract, such abstract or a copy thereof along with copies of any and all title
opinions covering this land shall be delivered to Lessor along with Lessor's
abstracts as soon as Lessee or its assignee has completed its title examination.

         21. CHECK METERS CLAUSE: In those instances where Lessee is acting as
operator of the leased premises, Lessor shall be entitled at Lessor's own cost-
and expense to install and maintain a check meter on any gas well upon such
leased premises in order to satisfy Lessor of the amount of production from any
such well, so long as same is installed under supervision of an engineer and
after due written notice to Lessee. In this connection, Lessee shall have the
right to make such installation itself of Lessor's check meter in order that
such installation does not interfere with Lessee's operations, provided such
installation is performed by Lessee within a reasonable time, not exceeding
thirty (30) days following written request of Lessor. Calibration of such meter,
its
<PAGE>   16
give the other sufficient written notice in advance of such tests so that each
party may, at its election, be present in person or by its representative to
observe adjustments, if any, which are made. If upon any test the metering
equipment in the aggregate is found to be inaccurate by two percent (2%) or
more, then following the test any metering equipment found to be inaccurate to
any degree shall be adjusted immediately to measure accurately. If for any
reason any meter is out of service or out of repair so that the quantity of gas
delivered through such meter cannot be ascertained or computed from the readings
thereof, the quantity of gas so delivered during such period same is out of
service or out of repair shall be estimated and agreed upon by the parties
hereto upon the basis of the best available data.

         22. AD VALOREM TAXES: Each party having an interest in the minerals
under the subject lands shall be responsible for rendering, adjusting,
protesting, and defending values on his interest in minerals and for the payment
of his proper share of ad valorem taxes. After production, all ad valorem taxes
shall be paid by the parties entitled to participate in revenue from production
proportionate to each party's percentage interest in revenue. Lessee and Lessor
agree to work together to obtain adjustments to which the parties may be
entitled as a result of mineral rights or depths not presently covered by this
lease or which may hereafter be released from the lease.

         23. ADMINISTRATIVE RELIEF: Lessee and Lessor agree that Lessor or
Lessor's representative shall have the concurrent rights and privileges with
Lessee to pursue and/or defend against proceedings before any administrative
agency without the joinder or consent of Lessee, and Lessee agrees that Lessor
shall have standing to pursue or defend any matter before any administrative
agency. Nothing herein shall in any way be construed as diminishing Lessee's
implied duties and obligations to protect and preserve Lessor's rights before
administrative agencies, but shall be supplemental of any such implied duties.

         24. INDEMNITY AGREEMENT: Lessee hereby indemnifies and agrees to hold
harmless Lessor, surface owner and their respective heirs and assigns, from and
against any and all liability, liens, demands, penalties, fines, remedial costs,
costs, response, restoration costs, judgments, suits and claims of any kind or
character caused or arising out of, in connection with, or relating to Lessee's
(including Lessee's servants, employees or its independent contractors)
operations in connection with and under the terms of this Lease, express and
implied, including, but not limited to, claims for injury or death of any
persons, or damage, loss or destruction of any property, real or personal, under
any theory of tort, contract or strict liability or violation of any
Environmental Law (as hereinafter defined) based upon a real or alleged act or
omission of Lessee, its agents, servants or employees or independent
contractors. Further, neither Lessor nor surface owner shall ever be liable for,
and Lessee indemnifies and agrees to hold harmless Lessor, surface owner, and
their respective successors, heirs and assigns from, any claims, demands, costs,
expenses, damages, loses, causes of action or suits for damages because of
injury to persons or property arising out of acts or omissions of Lessee, its
agents, employees, servants, contractors or any person acting under its
direction and control
<PAGE>   17
on said lands. Lessee further covenants and agrees to defend any suits or
actions brought against Lessor on account of said claims and to pay any
judgments, penalties, fines, remedial costs, and other obligations assessed
against Lessor resulting from any such claims, actions, suit or suits together
with all costs and expense relative to any such claims, actions or suits,
including attorney's fees, costs incurred in connection in defense of same,
including court costs. It is nevertheless understood, however, that Lessor, if
it so elects, shall have the right to participate in the defense of any such
claims, actions, suit or suits in which it may be a party without relieving
Lessee of the obligation to defend the same. In the event Lessor and/or any
surface owner under the above tract shall resort to a court of law or to
arbitration to enforce or interpret any provision, covenant, condition, duty,
obligation or commitment, whether expressed or implied, arising out of this
agreement, then Lessee shall reimburse Lessor or surface owner for reasonable
attorney's and expert witness fees incurred in such suit or arbitration, in the
event Lessor or surface owner should prevail in such cause of action or
arbitration.

         "Environmental Laws" mean any and all laws, statutes, regulations,
rules, orders, ordinances, permits or determinations of any governmental
authority pertaining to health or the environment in effect in any and all
jurisdictions in which the leased premises are located, including without
limitation, the Clean Air Act, as amended, the Federal Water Pollution Control
Act, as amended, the Rivers and Harbors Act of 1899, as amended, the Safe
Drinking Water Act, as amended, the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA"), as amended, the Superfund Amendments
and Reauthorization Act of 1986 ("SARA"), as amended, the Resource Conservation
and Recovery Act ("RCRA"), as amended, the Toxic Substances Control Act, as
amended, the Occupational Safety and Health Act, as amended, the Hazardous
Materials Transportation Act, as amended, and other federal, state and local
laws whose purpose is to conserve or protect health, the environment, wildlife
or natural resources. The terms "hazardous substance," "release" and "threatened
release" shall have the meanings specified in CERCLA, and the terms "solid
waste," "hazardous waste," and "disposal" (or "disposed") shall have the meaning
specified in RCRA, provided, however, that to the extent the laws of any state
in which the leased premises are located are applicable and have established a
meaning for the terms "hazardous substance," "release," "threatened release,"
"solid waste," "hazardous waste," and "disposal" (or "disposed") that is broader
than specified in CERCLA or RCRA, such broader meaning shall apply with respect
to the matters covered by such laws, and (the term "solid waste" shall include
all oil and gas exploration, development and production wastes, even if such
wastes are specifically exempt from classification as hazardous substances or
hazardous wastes pursuant to CERCLA or RCRA, or the state analogues to those
statutes. Lessee shall comply with all Environmental Laws in the conduct of all
drilling and producing operations on the leased premises and agrees that Lessee
shall not store nor dispose of solid waste or hazardous waste on the leased
premises.

         25. NO POOLING: Lessee is expressly denied the right to utilize any
rights granted herein to pool or unitize any part of the leased premises without
the prior written consent of Lessor.

         26. RECORDING: In lieu of filing this agreement for record in the
office of the County Clerk in which the acreage covered hereby is located,
Lessor and Lessee agree that a memorandum
<PAGE>   18
of this lease, making appropriate reference hereto, shall be filed for record in
said county. The provisions of this lease are binding upon the parties hereto,
their respective heirs, successors and assigns. Lessee, by its acceptance of
this lease, agrees and obligates itself to all terms and provisions of this
lease.

         27. OPERATING AGREEMENT: The leasehold interest granted to Lessee
hereunder is expressly made subject to the terms of that certain Operating
Agreement dated May 1, 1998, between Lessee, as Operator, and Lessor, as
Non-Operator, covering the leased premises.

         28. AFTER ACQUIRED TITLE: This lease is intended to grant, lease and
let unto Lessee all of Lessor's interest in the oil, gas or leased substances
on, in or under the leased premises which Lessor owned in the leased premises on
January 1, 1998, and is not intended to cover any additional mineral interests
which Lessor may acquire in the leased premises after January 1, 1998. In the
event Lessor acquires additional interests in the oil, gas or leased substances
on, in or under the leased premises after January 1, 1998, it is expressly
understood and agreed that such additional acquired interests shall not be
subject to or covered by the terms of this Lease and that Lessor shall own and

                   WARRANT TO PURCHASE SHARES OF COMMON STOCK

Michael Holdings, Inc., a Texas corporation (the "Company") hereby grants to
Dale L. Schwarzhoff, an individual, or registered assign ("Holder"), the number

1.       REGISTRATION AND TRANSFER

         1.1     General

                 The Company shall maintain books for the registration and
         transfer of the Warrants. Prior to due presentment for registration of
         transfer of the Warrants, the Company may deem and treat the
         registered Holder as the absolute owner thereof.

         1.2     Transfer

                 The Warrants may not be assigned or transferred without the
         prior written consent of the Company, in its sole and absolute
         discretion.

         1.3     Registration

                 Subject to Section 1.2 above, the Company shall register upon
         its books any transfer of the Warrants upon surrender of this Warrant
         Certificate to the Company accompanied (if so required by the Company)
         by a written instrument of transfer duly executed by the registered
         Holder or by a duly authorized attorney. Upon any such registration of
         transfer, a new Warrant Certificate shall be issued to the transferee
         and the surrendered Warrant Certificate shall be cancelled by the
         Company. If only a portion of the Warrants represented by this Warrant
         Certificate are transferred, a new Warrant Certificate shall also be
         issued to the transferor.

         2.      LOSS OR MUTILATION

                 Upon receipt by the Company of reasonable evidence of the
         ownership and the loss, theft, destruction, or mutilation of the
         Warrant Certificate and, in the case of loss, theft, or destruction,
         of indemnity reasonably satisfactory to the Company, or, in the case
         of mutilation, upon surrender and cancellation of the mutilated
         Warrant Certificate, the Company shall execute and deliver in
         substitution therefor a new Warrant Certificate representing an equal
         number of Warrants.

         3.      ADJUSTMENTS

                 The Purchase Price and the number of shares purchasable upon
         the exercise of the Warrants shall be subject to adjustment from time
         to time upon the occurrence of certain events described herein.





                                       2
<PAGE>   3

3.1      Purchase Price Adjustments

         a.      Split, Subdivision, or Combination of Shares

                 If the Company at any time while these Warrants remain
         outstanding and unexpired shall split (but excluding any split
         effected as a stock dividend, which shall be covered by Section 3.1G
         hereof), subdivide, or combine the securities as to which purchase
         rights hereunder exist, the Purchase Price shall be proportionately
         increased or decreased as appropriate.

         b.      Common Stock Dividends

                 If the Company at any time while these Warrants remain
         outstanding and unexpired shall pay a dividend or make any other
         distribution with respect to Common Stock payable in shares of Common
         Stock, then the Purchase Price shall be adjusted, from and after the
         record date for determining the shareholders entitled to receive any
         dividend or distribution, to that price determined by multiplying the
         Purchase Price in effect immediately prior to such date of
         determination by a fraction, the numerator of which shall be the total
         number of shares of Common Stock outstanding immediately prior to such
         dividend or distribution, and the denominator of which shall be the
         total number of shares of Common Stock outstanding immediately after
         such dividend or distribution.

         c.      Other Dividends

                 If the Company, at any time while these Warrants remain
         outstanding and unexpired, shall pay a dividend or make any other
         distribution with respect to Common Stock payable in stock (other than
         Common Stock) or other securities or property (but excluding cash),
         the Holder hereof shall be entitled to receive, upon exercise of the
         Warrants, in addition to the shares of Common Stock otherwise
         receivable upon exercise hereof, the same number and kind of stock or
         other securities and property which the Holder would have received had
         the Holder than held the shares of Common Stock receivable on exercise
         hereof on and before the record date of such dividend or distribution.





                                       3
<PAGE>   4
         d.      Reclassification and Recapitalization

                 In the event of any reclassification or recapitalization of
         the outstanding Common Stock (other than a change in par value), the
         Purchase Price and the number and type of securities to be received
         upon the exercise of the Warrant shall be appropriately adjusted in
         good faith by the Board of Directors of the Company to reflect such
         reclassification or recapitalization and to protect (i) the rights of
         the Holder to receive, upon the exercise hereof, the same amount of
         securities or property that it would have received had it exercised
         the Warrants immediately prior to the date for determination of
         Holders of Common Stock entitled to receive securities or property as
         a result of such reclassification or recapitalization, and (ii) the
         Holder's rights to appropriate adjustment upon any further stock
         dividend, stock split, reclassification, or recapitalization.

3.2     Adjustment of Number of Shares

                 Upon each adjustment in the Purchase Price pursuant to
         Sections 3.1(a) or (b) above, the number of shares of Common Stock
         purchasable hereunder shall be adjusted to the nearest whole share to
         the product obtained by multiplying the number of shares purchasable
         immediately prior to such adjustment in the Purchase Price by a
         fraction, the numerator of which shall be the Purchase Price
         immediately prior to such adjustment, and the denominator of which
         shall be the Purchase Price immediately after such adjustment.

3.3     Capital Reorganization, Merger, or Sale of Assets

                 If, at any time or from time to time, there shall be a merger
         or consolidation of the Company with or into another corporation
         (other than a merger in which the Company is the continuing
         corporation and which does not result in any change in 
         reclassification or the outstanding shares of Common Stock or other
         capital stock of the Company), or a sale of all or substantially all
         of the Company's properties and assets to any other person, the Holder
         shall thereafter be entitled to receive (and it shall be a condition
         to the consummation of any such merger, consolidation, or sale, that
         appropriate provision be made so that the Holder shall thereafter be
         entitled to receive), upon exercise of the Warrants, the kind and
         amount of shares of stock or other securities or property receivable
         upon such merger, consolidation, or sale, by a holder of the number of
         shares of Common Stock





                                       4
<PAGE>   5
         issuable upon exercise would have been entitled upon such merger,
         consolidation, or sale. In any such case, appropriate adjustment shall
         be made in the application of the provisions of this Section with
         respect to the rights of the Holder after the reorganization, merger,
         consolidation, or sale to the end that the provisions of this 
         Section 3 (including adjustment of the Purchase Price then in effect
         and the number of shares of Common Stock purchasable upon exercise of
         the Warrants) shall be applicable after that event in as nearly 
         equivalent a manner as may be practicable.

         3.4     Certificate as to Adjustment

                 Upon the occurrence of each adjustment or readjustment of the
         Purchase Price and the number of shares of Common Stock or other
         securities pursuant to this Section 3, the Company, at its expense,
         shall promptly compute such adjustment or readjustment in accordance
         with the terms hereof and cause its chief financial officer to verify
         such computation and prepare and furnish to the Holder a certificate
         setting forth such adjustment or readjustment and showing in detail
         the facts upon which such adjustment or readjustment is based. The
         Company shall, upon the written request at any time of the Holder,
         furnish or cause to be furnished to the Holder a like certificate
         setting forth (a) such adjustment or readjustment, (b) Purchase Price
         at the time in effect, and (c) the number of shares of Common Stock
         and the amount, if any, of other securities and/or property which at
         the time would be receivable upon the exercise of the Warrants. Such
         certificate shall set forth in reasonable detail such facts as may be
         necessary to show the reason for and manner of computing such
         adjustment.

         3.5     No Impairment

                 The Company will not take any action, by amendment of its
         Certificate of Incorporation or through any reorganization,
         recapitalization, transfer of assets, consolidation, merger,
         dissolution, issue or sale of securities, or any other voluntary
         action, specifically designed to avoid or seek to avoid the observance
         or performance of any of the terms to be observed or performed
         hereunder by the Company.

         3.6     Notices of Record Date

                 In the event of any taking by the Company of a record of the
         holders of any class of securities for the purpose of determining the
         holders thereof who are entitled to receive any dividend (other than





                                       5
<PAGE>   6
         a cash dividend) or other distribution, any rights to subscribe for,
         purchase, or otherwise acquire any shares of stock of any class or any
         securities or property, or to receive any other right, the Company
         shall mail to the Holder, not later than the later to occur of (i)
         fifteen (15) days prior to the date specified therein or (ii) the
         business day after determination by the Board of Directors of the
         record date to take such action, a notice specifying the date on which
         any such record is to be taken for the purpose of such dividend,
         distribution, or right, and the amount and character of such dividend,
         distribution, or right.

         3.7     No Fractional Shares

                 No fractional shares shall be issued upon the exercise of the
         Warrants and the number of shares of Common Stock issued shall be
         rounded to the nearest full share. Such rounding shall be determined
         on the basis of the total number of Warrants the Holder is at the time
         exercising and the number of shares of Common Stock issuable upon such
         aggregate exercise.

4.       EXERCISE OF WARRANTS

                 The purchase rights represented by these Warrants are
         exercisable by the Holder, in whole or in part, at any time and from
         time to time on or after the Exercise Date and on or prior to the
         Expiration Date. The Warrants may be exercised by surrender of this
         Warrant Certificate, with the Notice of Exercise attached hereto duly
         executed, to the principal executive office of the Company, presently
         located at 13101 Northwest Freeway, Suite 320, Houston, TX 77040 (or
         such other office or agency of the Company as it may designate by
         notice in writing to the registered Holder hereof at the address of
         such Holder appearing on the books of the Company, and shall be
         accompanied by payment in cash, cashier's check, or bank draft,
         payable to the Company, in an amount equal to the full purchase price
         for the shares of Common Stock with respect to which the Warrants are
         being exercised (hereinafter referred to as the "Shares"). The Company
         shall deliver a certificate or certificates representing the Shares as
         soon as practical, and, in any event, within thirty (30) days after
         the notice and payment shall be received. The certificate for the
         Shares shall be registered in the name of the person exercising the
         Warrants and shall be delivered, as provided above, to the written
         order of the person exercising the Warrants. All shares of Common
         Stock which may be issued upon the exercise of the Warrants as
         provided herein shall be fully paid and non-assessable and free





                                       6
<PAGE>   7
         from all taxes, liens, and charges, other than those created by or
         otherwise applicable to the Holder. Holder shall not be entitled to
         the privileges of share ownership, including without limitation the
         right to vote to receive dividends as to any shares of Common Stock
         not actually issued and delivered to it. Holder hereby certifies that
         these Warrants and all shares of Common Stock in the Company purchased
         or to be purchased by it pursuant to the exercise of the Warrants are
         being, or are to be, acquired by it for investment purposes and not
         with a view to or for resale in connection with any distribution or
         public offering thereof.

5.       GENERAL

                 The Company shall, at all times during the term of the
         Warrants, reserve and keep available out of its authorized but
         unissued shares of Common Stock such number of shares of Common Stock
         as will be sufficient to satisfy the requirements of this Warrant
         Certificate; and if, at any time, the number of authorized but
         unissued shares of Common Stock shall be insufficient to effect the
         exercise of the Warrants, in addition to such other remedies as shall
         be available to the Holder, the Company shall use its reasonable best
         efforts to take such corporate action as may, in the opinion of the
         Company, be necessary to increase its authorized but unissued shares of
         Common Stock to such number as shall be sufficient for such purposes.
         The Company shall pay all original issue and transfer taxes with
         respect to the issue of shares of Common Stock pursuant hereto and all
         other fees and expenses necessarily incurred by the Company in
         connection therewith, and will, from time to time, use its reasonable
         best efforts to comply with all laws and regulations which, in the 
         opinion of the Company, shall be applicable thereto.      

6.       LEGENDS

                 The Holder understands that neither the Warrants nor the
         shares have been registered under the Act or any state securities laws
         and will be issued in reliance on an exception from the registration
         requirements thereof.  Holder acknowledges that the certificates 
         evidencing the Shares shall bear the following legend:

                 The securities represented by this certificate have not been
                 registered under the Securities Act of 1933 (the "Act") or any
                 applicable state securities laws; they have

                 been acquired by the Holder for investment and may not be
                 pledged, hypothecated, sold, transferred, or otherwise disposed
                 of except (A) pursuant to an effective registration statement
                 or (B) upon opinion of counsel acceptable to a Company,
                 pursuant to an exemption from registration under the Act and
                 such applicable state securities laws or the rules and
                 regulations promulgated thereunder.                     

7.       NOTICES

                 Any notice required by the provisions of this Warrant
         Certificate to be given to the Holder shall be deemed given three (3)
         days after it is deposited in the U.S. mail, certified and return
         receipt requested, addressed to the Holder at its address appearing on
         the books of the Company or on the date actually delivered in person.

8.       GOVERNING LAW

                 This Warrant Certificate shall be governed by and construed in
         accordance with the laws of the state of Texas.

         IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to

                             MICHAEL HOLDINGS, INC.

               FIRST AMENDED AND RESTATED SHAREHOLDERS' AGREEMENT


          THIS FIRST AMENDED AND RESTATED SHAREHOLDERS' AGREEMENT (this
"Agreement") dated as of December 4, 1996, by and between MICHAEL HOLDINGS, 
INC., a Texas corporation (the "Corporation"), and each of the individuals and
entities described on Schedule A attached hereto and incorporated herein by
reference, all of whom appear as signatories hereto (each sometimes hereinafter
referred to individually as a "Shareholder" and collectively as the
"Shareholders"), and the spouse of each of the Shareholders, if any;

                              W I T N E S S E T H:

          WHEREAS, the Corporation is incorporated under the laws of the State
of Texas with an authorized capitalization of 100,000,000 shares of common
stock, $.01 par value (the "Common Stock") and 50,000,000 shares of preferred
stock, $.01 par value;

          WHEREAS, all of the Common Stock currently issued and outstanding is
owned by the Shareholders as reflected on Schedule A attached hereto and
incorporated herein by reference;

          WHEREAS, the Corporation and the Shareholders desire to promote their
mutual interests and the interests of the Corporation by entering into certain
agreements relating to the ownership and transferability of the Common Stock;

          NOW, THEREFORE, in consideration of the mutual promises contained
herein and other good and valuable consideration, the receipt, adequacy, and
sufficiency of which are hereby acknowledged, it is hereby agreed as follows:

          1.   Definitions. As used in this Agreement:

          (a)  Stock.  The term "Stock" means the Common Stock of the
     Corporation (whether presently or hereafter issued and outstanding) and
     any security of the Corporation convertible into such stock and any right
     to purchase or acquire any such stock or any security convertible into
     such stock.  Moreover, all references herein to Stock owned by any
     Shareholder include the community interest, if any, of the spouse of such
     Shareholder in such Stock.

          (b)  Shareholders.  The term "Shareholders" includes each person (and
     such person's spouse) and entity identified as a Shareholder on the
<PAGE>   2
     signature pages hereof as well as each other person (and such person's
     spouse) and entity as may hereafter become holders of the Stock of the
     Corporation, and shall include the heirs, executors, administrators,
     successors and assigns of a Shareholder.

          (c)  Disposition.  The term "Disposition" means any sale, assignment,
     gift, exchange, distribution, charge, transfer, pledge, mortgage or other
     encumbrance, or any other disposition of Stock (or any interest therein)
     whatsoever, whether voluntary or involuntary, direct or indirect, and each
     and every transaction occurring by operation of law or otherwise, which has
     the purpose or effect of making one or more of the following changes:

               (i)   a change in the ownership of any of the Stock covered by
          this Agreement or any stock certificate or certificates representing
          such shares of Stock; or

               (ii)  in the case of a person who is not a natural person, a
          change in the identity, ownership or control of the holder or owner of
          the legal or equitable title of or to any of the shares of Stock
          covered by this Agreement or any stock certificate or certificates
          representing such shares of Stock;

     and shall include the failure of a Shareholder to succeed to the community
     interest of such Shareholder's spouse in the Stock upon termination of the
     marital relationship of the Shareholder by death or divorce; provided,
     however, that such term shall not include any transfer pursuant to or
     resulting from the acquisition by a Shareholder of all or any part of the
     interest, community or otherwise, of such Shareholder's spouse in any
     shares of Stock covered by this Agreement.

          (d)  Agreed Value Per Share of Stock. The term "Agreed Value Per Share
     of Stock" means the fair market value per share of Stock as determined
     from time to time by the Board of Directors of the Corporation. If any
     Shareholder, or his heirs, executor, administrator or former spouse,
     required to offer or sell Stock under Sections 4, 5, 6, 8 or 9 at such
     price objects to the Agreed Value Per Share of Stock determined as set
     forth above and notifies the Corporation and all of the other Shareholders
     of such objection within ten days of the respective Trigger Date (as
     hereinafter defined), then the Agreed Value Per Share of Stock on the
     Trigger Date (as hereinafter defined), or a date as close as is reasonably
     possible to the Trigger Date, to be determined as soon as possible after
     the Trigger Date, shall be determined by an independent appraiser chosen
     by the Board of Directors of the Corporation who shall be experienced in
     valuation of privately held



                                      -2-
<PAGE>   3
     companies owning energy reserves as a substantial portion of their asset
     value. Such appraiser shall be required to determine the Agreed Value Per
     Share of Stock, taking into consideration such factors as he/she deem
     advisable. In determining the value of oil and gas reserves, the appraisal
     firm shall attribute a value of ninety percent (90%) of proved reserves,
     sixty percent (60%) of proved behind pipe reserves, and twenty-five percent
     (25%) of proved undeveloped reserves, all at a value based upon the
     appraiser's best estimate of future oil and gas prices and utilizing a
     present value discounting factor of 10%. All other assets and all
     liabilities shall be determined as of the regular unaudited balance sheet
     of the Corporation as determined from time to time. All fees and expenses
     incurred in connection with such appraisal shall be borne one-half (1/2) by
     the Corporation and one-half (1/2) by the objecting Shareholders.

          (e)  Trigger Date. The term "Trigger Date" means (i) in the case of a
     purchase of Stock under Section 4 hereof, the date the written notice
     specified in Section 4(a) is sent by the Corporation, (ii) in the case of a
     purchase of Stock under Section 5 hereof, the date of death of the spouse
     of the Shareholder or the date the decree of divorce of the Shareholder
     becomes a final judgment, whichever is applicable, (iii) in the case of a
     purchase of Stock under Section 6 hereof, the date on which the Selling
     Shareholder sends the Corporation the Offering Notice required by Section
     6, or (iv) in the case of a purchase of Stock under Section 9, the date of
     death of the Shareholder.

          (f)  Determination Date. The term "Determination Date" means (i) in
     all cases where an appraisal is not required to determine the purchase
     price of the Stock being sold, ten days after the Trigger Date, and (ii) in
     all cases where an appraisal under Section 1(d) is required to determine
     the purchase price of the Stock being sold, the date upon which the report
     with respect to the final appraisal required thereunder is delivered to the
     Corporation.

          2.   Provisions of General Applicability. For purposes of this
Agreement:

          (a)  Pro Rata Offers of Stock. Whenever any Shareholder is required
     under this Agreement to offer Stock to the Shareholders, such offer shall
     be deemed to be made, to the Shareholders pro rata in accordance with their
     respective holdings at the time of the offer of, shares of Stock
     (determined exclusive of the Stock held by the offering Stockholder) or in
     such other proportions as all of the Shareholders (excluding the offering
     Shareholder) may agree upon among themselves. Except as may otherwise be
     agreed among all Shareholders (excluding the offering Shareholder) each
     such Shareholder to whom Stock is so offered, shall have the right to



                                      -3-
<PAGE>   4
     purchase that proportion of the number of shares of such offered Stock
     which the number of shares of Stock owned by each such Shareholder bears to
     the total number of shares of Stock owned by all such Shareholders electing
     to accept the offer.

          (b)  Corporate Action.  Whenever any Stock is offered to the
     Corporation pursuant to this Agreement, the determination of the
     Corporation to accept or reject such offer shall be made by the Board of
     Directors of the Corporation. Any director of the Corporation who is (i)
     the offering Shareholder, (ii) if the offering Shareholder is a
     corporation, a director, officer or shareholder of the offering
     Shareholder, (iii) if the offering Shareholder is a trust, a trustee or
     beneficiary of the offering Shareholder, or (iv) if the offering
     Shareholder is a partnership, a partner of such partnership or an officer,
     director or shareholder of any corporate partner of such partnership, shall
     be disqualified and abstain from voting on any such determination. In the
     event that all directors are disqualified and abstain pursuant to the
     preceding sentence, then the determination of the Corporation to accept or
     reject such offer shall be made by vote of the Shareholders (other than the
     offering Shareholder).

          3.   Rights of First Refusal on Stock.  If any Shareholder desires to
sell any Stock owned or held by such Shareholder in a bona fide third-party
transaction for cash or a combination of cash and one or more promissory notes
or other debt securities secured only by such Stock, and if all Shareholders do
not consent to such  sale as provided in Section 7 or the transaction is not
otherwise permitted by this Agreement, then such Shareholder (for purposes of
this Section 3, the "Selling Shareholder"), prior to making such sale, shall
first offer such shares (for purposes of this Section 3, the "Option Stock")
for sale to the Shareholders as set forth in Section 2(a) hereof, and if such
offer is not accepted by the Shareholders, then to the Corporation, all in
accordance with the following provisions and on the terms and conditions set
forth in this Section 3. Each Shareholder agrees that he will not sell any
Stock to any third party for consideration other than cash, promissory notes or
other securities.

          (a)  Option Price; Terms; Offering Notices.  The price at which the
     Selling Shareholder shall be required to offer the Option Stock, and the
     terms of such offer, shall be the price at which and the terms upon which
     any proposed third-party purchaser shall have offered in writing to
     purchase the Option Stock from the Selling Shareholder and which the
     Selling Shareholder is prepared to accept. Each offer required to be made
     by the Selling Shareholder pursuant to this Section 3 shall be made by a
     written notice (for  purposes of this Section 3, the "Offering Notice") 
     which shall state that the offer is being made pursuant to Section 3 of 
     this Agreement and which shall set forth the number of shares of Option 
     Stock, the name or names of the proposed purchaser or purchasers of the 
     Option Stock, the price offered by



                                      -4-
<PAGE>   5
     such proposed purchaser or purchasers for the Option Stock (the "Option
     Price"), the method of payment of the Option Price and the scheduled date
     of consummation of such proposed sale. A copy of the written offer from any
     proposed third-party purchaser shall be attached to each Offering Notice.

          (b)  Offer to Shareholders. The Selling Shareholder shall first offer
     the Option Stock to the Shareholders, as set forth in Section 2(a) hereof,
     by delivering an Offering Notice to each of them. Within 30 days from the
     date of receipt of the Offering Notice, each of the Shareholders shall
     deliver to the Selling Shareholder a reply notice accepting or rejecting
     the offer of the Option Stock. If by such reply notice one or more of the
     Shareholders accepts the offer made by the Selling Shareholder, the reply
     notice shall constitute an agreement binding on the Selling Shareholder and
     those Shareholders accepting the offer to sell and purchase the Option
     Stock at the Option Price. If within such 30-day period, one or more
     Shareholders shall have failed to deliver one or more reply notices
     accepting the offer of the Selling Shareholder as to all of the Option
     Stock, each of such Shareholders shall be deemed to have rejected such
     offer.

          (c)  Lapse of Options. If none of the options provided for in this
     Section 3 have been exercised, the Selling Shareholder may sell not less
     than all of the Option Stock at any time within, but not subsequent to, 90
     days after the lapse of all options granted pursuant to this Section 3;
     provided, however, that (i) no sale of all or a part of the Option Stock
     shall be made at any price lower than the Option Price or on terms
     materially different from those specified in the Offering Notice or to any
     person or persons other than the person or persons specified in the
     Offering Notice, and (ii) the person or persons to whom the Option Stock is
     to be transferred enter into an Addendum Agreement in substantially the
     form of Exhibit A attached hereto, pursuant to which such person or persons
     agree to be bound by all of the terms and provisions of this Agreement. If
     after the lapse of the 90-day period the Option Stock shall not have been
     sold, all of the provisions of this Agreement, including the provisions of
     this Section 3, shall apply to any future Disposition or proposed
     Disposition of Stock owned by the Selling Shareholder. 

          (d)  Consummation of Purchases. Each transaction of purchase and sale
     of Option Stock pursuant to this Section 3 shall be completed by delivery
     of the stock certificates representing the Option Stock endorsed in blank,
     or accompanied by duly executed stock powers or assignments, as
     appropriate, and by actual registration of the transfer of the Option Stock
     on the books of the Corporation upon payment of the purchase price to the
     Selling Shareholder. Any such transaction shall be closed at such time and




                                      -5-
<PAGE>   6
     place as shall be agreed upon by the parties thereto, or, if no such
     agreement is reached, at the principal office of the Corporation on the
     thirtieth (30th) day following the later of the expiration of the thirty
     day reply period described in Section 3(b) or the date of delivery of the
     last reply notice given in connection with such transaction or, if such
     day shall not be a business day, on the first business day thereafter
     during normal business hours.

          4.   Options Upon Termination of Marriage of an Individual
Shareholder. If the marriage of an individual Shareholder is terminated by the
death of his spouse or by divorce, and if such Shareholder does not succeed to
all of his spouse's community interest, if any, in the Stock held by him at the
time of such termination, then such Shareholder shall notify the Corporation
within ten days of such event, and shall have a first option, and if such
Shareholder does not exercise such option, the Shareholders shall have a second
option, in accordance with the provisions of Section 2(a) hereof, and if such
Shareholders do not exercise such option, the Corporation shall have a third
option, to purchase from the former spouse of such Shareholder, or from the
executor, administrator or heirs of the former spouse of such Shareholder, as
the case may be, all (but not less than all) of the interest of such former
spouse, heirs, executor or administrator, as the case may be, in such shares
(the "Option Stock"), in accordance with the following provisions of this
Section 4. As used in the following paragraphs of this Section 4, the term
"Selling Shareholder" means the former spouse of any individual Shareholder who
shall have been divorced or, in the event of the death of the spouse of a
Shareholder, the executor, administrator or heirs of such spouse's estate, as
the case may be, and the term "Individual Shareholder" means the Shareholder
who shall have been divorced or whose spouse shall have died.

          (a)  Option Price. The price per share at which the Individual
     Shareholder, the Shareholders or the Corporation shall be entitled to 
     purchase the Option Stock shall be the Agreed Value Per Share of Stock at
     the Trigger Date. The price at which shares of Stock are purchasable under
     this Section 4 is referred to in this Section 4 as the "Option Price."
     Within 30 days following the Determination Date, the Corporation shall send
     to each Shareholder a notice setting forth the Option Price.

          (b)  Exercise by Individual Shareholder. If the Individual
     Shareholder wishes to exercise his option with respect to the Option
     Stock, he shall do so by delivering to the Selling Stockholder, within 30
     days from the receipt of the notice from the Corporation provided for in
     paragraph (a) of this Section 4, a notice to such effect. If by such notice
     the Individual Shareholder elects to exercise such option, such notice
     shall constitute an agreement binding on the Selling Shareholder and the
     Individual Shareholder to sell and purchase the Option Stock at the Option
     Price.

          (c)  Exercise by Shareholders. If the option of the Individual
     Shareholder shall not be exercised by him as provided in paragraph (b) of
     this



                                      -6-
<PAGE>   7
         Section 4, and if any Shareholders wish to exercise their option with
         respect to the Option Stock, they shall do so by delivering to the
         Selling Shareholder, within 30 days from the expiration of the 30-day
         period referred to in paragraph (b) of this Section 4, a notice to such
         effect. If by such notice, any such Shareholders elect to exercise such
         option, such notice shall constitute an agreement binding on the
         Selling Shareholder and such Shareholders to sell and purchase the
         Option Stock at the Option Price.

              (d)  Exercise by Corporation. If the option in favor of the
         Shareholders shall not be exercised by any them as provided in
         paragraph (c) of this Section 4, and if the Corporation wishes to
         exercise its option with respect to the Option Stock, then the
         Corporation shall deliver to the Selling Shareholder, within 30 days
         following the expiration of the 30 days following the expiration of the
         30-day period referred to in paragraph (c) of this Section 4, a notice
         stating its intent to exercise such option. Such notice shall
         constitute an agreement binding on the Selling Shareholder and the
         Corporation to sell and purchase the Option Stock at the Option Price.

              (e)  Lapse of Options. If none of the options provided for in this
         Section 4 have been timely exercised, then such options shall expire,
         but all of the provisions of this Agreement shall apply to any future
         Disposition or Proposed Disposition of Stock owned or held by the
         Selling Shareholder.

              (f)  Consummation of Purchases. If any option provided for in this
         Section 4 shall be timely exercised as provided in this Section 4, the
         purchase and sale of the Option Stock shall be completed by delivery of
         the certificates representing such Option Stock endorsed in blank, or
         accompanied by duly executed stock powers or assignments, as
         appropriate, and by actual registration of the transfer of such Option
         Stock on the books of the Corporation upon payment in cash of the
         Option Price to the Selling Shareholder. Any such transaction shall be
         closed as such time and place as shall be agreed upon by the parties
         thereto, or, if no such agreement is reached, at the principal office
         of the Corporation on the tenth (10th) day following the date of
         delivery of any notice of exercise given to the Selling Shareholders
         pursuant to paragraph (b),(c) or (d) of this Section 4, whichever is
         applicable, or if such day shall not be a business day, on the first
         business day thereafter during normal business hours.

          5.   Involuntary Disposition of Stock. Upon the reasonable belief of
a Shareholder that any of the shares of Stock owned by such Shareholder are or
will be subject to an involuntary Disposition, and in any event upon or prior to
any involuntary Disposition of such shares of Stock, such Shareholder shall
deliver an offering notice (the "Offering Notice") to the Corporation and to the
Shareholders setting forth the events giving rise to the delivery of the
Offering Notice. Upon




                                      -7-
<PAGE>   8
receipt of the Offering Notice by the Corporation, the Shareholders shall have
a first option, as set forth in Section 2(a) hereof, and if such Shareholders
do not exercise such option, the Corporation shall have a second option, to
purchase from such Shareholder all (but not less than all) of such
Shareholder's interest in such shares (for purposes of this Section 5 the
"Option Stock"), in accordance with the following provisions of this Section 5.
For purposes of this Section 5, "involuntary Disposition" shall include,
without limitation, any Disposition or other transfer of shares of Stock
pursuant to or by reason of or under judicial order, legal or equitable
process, execution, attachment or enforcement of a pledge, trust or other
security interest or encumbrance. As used in the following paragraphs of this
Section 5, the term "Selling Shareholder" means the Shareholder who owns such
shares of stock subject to the involuntary Disposition, or his representative,
as the case may be.

          (a) Option Price. The price per share at which the Shareholders or the
     Corporation shall be entitled to purchase Option Stock shall be the Agreed
     Value Per Share of Stock at the Trigger Date. The price at which shares of
     Stock are purchasable under this Section 5 is referred to in this Section 5
     as the "Option Price." Within ten (10) days following the Determination
     Date, the Corporation shall send to each Shareholder a notice setting forth
     the Option Price.

          (b) Exercise by Shareholders. If any Shareholder wishes to exercise
     his option with respect to the Option Stock, he shall do so by delivering
     to the Selling Shareholder, within ten (10) days from the receipt of the
     notice from the Corporation provided for in paragraph (a) of this Section
     5, a notice to such effect. If by such notice, any such Shareholder elects
     to exercise such option, such notice shall constitute an agreement binding
     on the Selling Shareholder and such Shareholder to sell and purchase the
     Option Stock at the Option Price.

          (c) Exercise by Corporation. If the option in favor of the
     Shareholders shall not be exercised by any of them as provided in paragraph
     (b) of this Section 5, and if the Corporation wishes to exercise its option
     with respect to the Option Stock, then the Corporation shall deliver to the
     Selling Shareholder, within ten (10) days following the expiration of the
     10-day period referred to in paragraph (b) of this Section 5, a notice
     stating its intent to exercise such option. Such notice shall constitute an
     agreement binding on the Selling Shareholder and the Corporation to sell
     and purchase the Option Stock at the Option Price.

          (d) Lapse of Options. If none of the options provided for in this
     Section 5 shall have been exercised within the applicable 10-day periods
     set forth above, then such options shall expire, but all of the provisions
     of this


                                      -8-
<PAGE>   9
         Agreement shall apply to any future Disposition or proposed Disposition
         of Stock owned or held by the Selling Shareholder.

              (e)  Consummation of Purchases. If any option provided for in this
         Section 5 shall be timely exercised as provided in this Section 5, the
         purchase and sale of the Option Stock shall be completed by delivery of
         the certificates representing such Option Stock endorsed in blank, or
         accompanied by duly executed stock powers or assignments, as
         appropriate, and by actual registration of the transfer of such Option
         Stock on the books of the Corporation upon payment in cash of the
         Option Price to the Selling Shareholder. Any such transaction shall be
         closed at such time and place as shall be agreed upon by the parties
         thereto, or, if no such agreement is reached, at the principal office
         of the Corporation on the tenth (10th) day following the date of
         delivery of any notice of exercise given to the Selling Shareholder
         pursuant to paragraph (b) or (c) of this Section 5, whichever is
         applicable, or if such day shall not be a business day, on the first
         business day thereafter during normal business hours.

         6. Permitted Dispositions. No Disposition of Stock may be made by any
Shareholder (a) except in accordance with the terms of this Agreement or (b) (i)
unless all Shareholders other than the Shareholder making the Disposition
consent in writing to the transfer and (ii) any person other than a current
Shareholder to whom shares are to be so transferred executes an Addendum
Agreement in the form of Exhibit A attached hereto, pursuant to which such
person agrees to be bound by all of the terms and provisions of this Agreement.

         7. Voting for Directors. In connection with any annual or special
meeting of the Shareholders for the purposes of electing Directors to the Board
of Directors of the Corporation, each of Glenn D. Hart ("Hart"), Michael G.
Farmar, Stanley T. Polak, Jerry Holditch and Jim R. Smith shall have the right
to designate one nominee for membership on the Board of Directors of the
Corporation. The foregoing right to designate a nominee to the Board of
Directors shall terminate for any individual who no longer is a Shareholder, and
upon such occurrence that person's nominee on the Board of Directors shall
immediately resign. Each of the Shareholders covenant and agree that they will
vote all of their shares of Stock (i) in such a manner that the number of
Directors to serve on the Board of Directors of the Corporation shall be, and
shall thereinafter remain, five (5); and (ii) for each nominee designated by
certain of the Shareholders pursuant to this Section 7. Notwithstanding anything
to the contrary contained herein, no matter requiring approval of the
Shareholders shall be deemed to have taken place unless not only the requisite
vote of the outstanding shares does occur, but in addition the approval of Hart
shall have been procured so long as Hart owns at least thirty percent (30%) or 
more of the issued and outstanding shares of the Corporation.

         8. Death of Individual Shareholders.

              (a)  Purchase by Corporation. Upon the death of any individual
         Shareholder, the Corporation will be obligated to purchase the Stock
         owned by the deceased Shareholder, and the estate of said Shareholder
         will sell all such shares of Stock now owned or hereafter acquired by
         such Shareholder or his or her spouse, if any.

              (b)  Purchase Price. The price per share at which the Corporation
         will purchase the Stock (the "Purchase Price") will be equal to the
         Agreed Value Per Share of Stock as of the Trigger Date.

              (c)  Consummation of Purchases. Upon receipt of the cash payment
         due and owing for the purchase of the Stock of the deceased
         Shareholder, the estate of the deceased Shareholder will deliver the
         certificate(s) representing the Stock being purchased by the
         Corporation, endorsed in blank or accompanied by duly executed stock
         powers or assignments, as appropriate, and by actual registration of
         the transfer of the Stock on the books of the Corporation upon payment
         of the Purchase Price to the estate of the deceased Shareholder. Any
         such transaction will be closed at such time and place as agreed upon
         by the parties thereto, or, if no such agreement is reached, at the
         principal office of the Corporation on the ninetieth (90th) day
         following the Trigger Date or, if such day is not a business day, on
         the first business day thereafter, during normal business hours.

         9. Disposition by Shareholder upon Termination of Employment.

              (a) Obligation of the Company. Upon the termination of any
         salaried employee Shareholder's employment with the Corporation for any
         reason (other than death which is covered by Section 8 herein or
         termination by the Corporation without cause), including (but not
         limited to) retirement, resignation, expiration of the term of an
         employment agreement, or termination by the Corporation with cause of a
         Shareholder, the Corporation shall promptly notify the other
         Shareholders of such event. The other Shareholders shall have a first
         option, in accordance with the provisions of Section 2(a) hereof, and
         if none of the Shareholders exercise such option, the Corporation shall
         have a second option, to purchase from the former employee Shareholder
         all (but not less than all) of the interest of such former employee in
         such shares (the "Option Stock"), in accordance with the following
         provisions of this Section 9. As used in the following paragraphs of
         this Section 9, the term "Selling Shareholder" means the former
         employee Shareholder.



                                      -10-

<PAGE>   11
              (b)  Option Price. The price per share at which the Selling
         Shareholder, the other Shareholders or the Corporation shall be
         entitled to purchase the Option Stock shall be the Agreed Value Per
         Share of Stock at the Determination Date. The price at which shares of
         Stock are purchasable under this Section 9 is referred to in this
         Section 9 as the "Option Price." Within thirty (30) days following the
         Trigger Date, the Corporation shall send to each Shareholder a notice
         setting forth the Option Price.

              (c)  Exercise by Shareholders. If the other Shareholders wish to
         exercise their option with respect to the Option Stock, they shall do
         so by delivering to the Selling Stockholder, within thirty (30) days
         from the delivery of the notice referred to in paragraph (b) of this
         Section 9, a notice to such effect. Such notice shall constitute an
         agreement binding on the Selling Shareholder and such Shareholders to
         sell and purchase the Option Stock at the Option Price.

              (d)  Exercise by Corporation. If the option in favor of the other
         Shareholders shall not be exercised by any of them as provided in
         paragraph (c) of this Section 9, and if the Corporation wishes to
         exercise its option with respect to the Option Stock, then the
         Corporation shall deliver to the Selling Shareholder, within thirty
         (30) days following the expiration of the 30-day period referred to in
         paragraph (c) of this Section 9, a notice stating their intent to
         exercise such option. Such notice shall constitute an agreement binding
         on the Selling Shareholder and the Corporation to sell and purchase the
         Option Stock at the Option Price.

              (e)  Lapse of Options. If none of the options provided for in this
         Section 9 have been timely exercised, then such options shall expire,
         but all of the provisions of this Agreement shall apply to any future
         Disposition or Proposed Disposition of Stock owned or held by the
         Selling Shareholder.

              (f)  Consummation of Purchases. If any option provided for in this
         Section 9 shall be timely exercised as provided in this Section 9, the
         purchase and sale of the Option Stock shall be completed by delivery of
         the certificates representing such Option Stock endorsed in blank, or
         accompanied by duly executed stock powers or assignments, as
         appropriate, and by actual registration of the transfer of such Option
         Stock on the books of the Corporation upon payment in cash of the
         Option Price to the Selling Shareholder. Any such transaction shall be
         closed at such time and place as shall be agreed upon by the parties
         thereto, or, if no such agreement is reached, at the principal office
         of the Corporation on the tenth (10th) day following the date of
         delivery of any notice of exercise given to the Selling Shareholder
         pursuant to paragraph (c) or (d) of this Section 9, whichever is


                                      -11-
<PAGE>   12
     applicable, or if such day shall not be a business day, on the first
     business day thereafter during normal business hours.

          10. Investment Representation and Legend on Stock Certificates. Each
of the Shareholders hereby represents that as of the date any Stock was or will
be acquired by such Shareholder, such Stock was or will be acquired for such
Shareholder's own account, for investment and not with a view to the
distribution thereof. Each of the Shareholders understands that any Stock which
has been or will be acquired by such Shareholder has not been and will not be
registered under the Securities Act of 1933, as amended (the "Securities Act"),
or the securities laws of any state, pursuant to an exemption from the
registration provisions of the Securities Act and such state securities laws.
Each of the Shareholders hereby agrees that the Stock which has been or will be
acquired by such Shareholder pursuant to an exemption from the registration
provisions of the Securities Act and applicable state securities laws shall not
be sold, transferred, pledged or hypothecated unless the sale of such Stock is
registered under the Securities Act and any applicable state securities laws or
unless there is furnished an opinion of counsel satisfactory to the Corporation
that registration of such Stock under the Securities Act and applicable state
securities laws is not required. All certificates representing shares of Stock
now owned or hereafter acquired by the Shareholders shall contain an
appropriate reference on the face thereof to the following legend which shall
be endorsed on the reverse side of each such certificate.

     "The transfer of the shares of stock represented by this certificate is
     restricted by the terms and conditions of a First Amended and Restated
     Shareholders' Agreement (the "Agreement") dated as of December 4, 1996,
     among the Corporation and all of the holders of Stock of the Corporation.
     As more fully set forth in the Agreement, such shares have not been
     registered under the Securities Act of 1933, as amended (the "Securities
     Act"), or the securities laws of any state, have been acquired for
     investment and not with a view to distribution thereof, and may not be
     sold, offered for sale, transferred, pledged or hypothecated unless the
     sale, transfer, pledge or hypothecation of such shares is registered under
     the Securities Act and any applicable state securities laws or unless
     there is furnished an opinion of counsel satisfactory in form and
     substance to the Corporation that registration of such shares under the
     Securities Act and any applicable state securities laws is not required. A 
     copy of the Agreement is on file at the offices of the Corporation."

Each Shareholder understands that the Corporation is under no obligation to
register the Stock under the Securities Act. The provisions of this Section 10
shall remain in effect until, in the opinion of counsel for the Corporation,
they are no longer required.

          11. Notices. Any offer, notice, request, reply, instruction or other
communication (herein severally and collectively called "Notice") in this
Agreement provided or permitted to be given to the Corporation or to any
Shareholder or spouse of a Shareholder or executor or administrator of a
deceased Shareholder shall be in writing and shall be considered to have been
sent when personally


                                      -12-
<PAGE>   13
delivered or sent, first class, registered or certified mail, return receipt
requested, postage prepaid. Notice sent in the United States mail, in the
manner described, shall be effective and deemed to be received by the addressee
upon the expiration of three (3) days after deposit. Notice given in any other
manner shall be effective only when received by the party to be notified. For
purposes of Notice, the address of the Corporation shall be 13101 Northwest
Freeway, Suite 320, Houston, Texas 77040, and the respective addresses of the
Shareholders shall be the addresses hereinafter set forth next to the
signatures to this Agreement of each of the Shareholders. Any party to this
Agreement shall have the right to change his address for the purposes of this
Agreement by giving at least three (3) days' written notice of such change of
address to each of the other parties hereto in the manner set forth in this
Agreement.

          12. Necessary Documents. If under the terms of this Agreement the
Stock of any Shareholder is purchased, such Shareholder or the spouse of any
Shareholder or the executor or administrator of such Shareholder, as the case
may be, shall execute and deliver at the closing as provided in this Agreement
all necessary documents that may be reasonably required for accomplishing a
complete transfer of such Stock for the purposes of the purchase contemplated
hereby in this Agreement.

          13. Miscellaneous Provisions.

          (a) Governing Law. This Agreement shall be subject to and governed by
     the laws of the State of Texas.

          (b) Arbitration. If a dispute arises out of or relates to this
     Agreement, or the breach thereof, and if said dispute cannot be settled
     through negotiation, the Parties agree first to try in good faith to
     settle the dispute by mediation under the Commercial Mediation Rules of
     the American Arbitration Association, before resorting to arbitration,
     litigation, or some other dispute resolution procedure as required by this
     Section 13(b). Failing an adequate resolution by mediation, any
     controversy or claim arising out of or relating to this Agreement or the
     transactions contemplated hereby, including any controversy or claim
     arising out of or relating to the Parties' decision to enter into this
     Agreement, shall be settled by binding arbitration. There shall be one
     arbitrator to be mutually agreed upon by the Parties involved in the
     controversy and to be selected from the Judicial Panel of the Center for
     Public Resources (or successor panel, if any). If within 45 days after
     service of the demand for arbitration the Parties are unable to agree upon
     such an arbitrator who is willing to serve, then an arbitrator shall be
     appointed by the American Arbitration Association in accordance with its
     rules. Except as specifically provided in this Section 13(b), the
     arbitration shall be conducted in accordance with the Commercial
     Arbitration Rules of the American Arbitration Association. The arbitrator
     shall not render an award of punitive damages. Any arbitration hereunder
     shall be held in Harris




                                      -13-
<PAGE>   14
         County, Texas. Except as otherwise specifically provided hereinafter,
         expenses related to the arbitration, including counsel fees, shall be
         borne by the Party incurring such expenses. The fees of the arbitrator
         and of the American Arbitration Association, if any, shall be divided
         equally among the Parties involved in the controversy. Judgement upon
         the award rendered by the arbitrator (which may, if deemed appropriate
         by the arbitrator, include equitable or mandatory relief with respect
         to performance of obligations hereunder) may be entered in any court of
         competent jurisdiction. If any legal action or other proceeding is
         brought for the enforcement of this Agreement, or because of an alleged
         dispute, breach, default or misrepresentation in connection with any of
         the provisions of this Agreement, the successful or prevailing Party or
         Parties shall be entitled to recover reasonable attorneys' fees and
         other costs incurred in that action or proceeding in addition to any
         other remedies to which it or they may be entitled at law or equity.

              (c)  Gender. Whenever the context requires, the gender of all
         words used herein shall include the masculine, feminine and neuter, and
         the number of all words shall include the singular and plural.

              (d)  Binding Effect. This Agreement shall be binding upon the
         Corporation, the Shareholders, the spouses of the Shareholders and
         their heirs, executors, administrators, successors and assigns.

              (e)  Amendment. This Agreement may be amended from time to time by
         an instrument in writing signed by all those who are parties to this
         Agreement at the time of such amendment, such instrument being
         designated on its face as an "Amendment" to this Agreement.

              (f)  Termination. This Agreement shall terminate automatically
         upon (i) the bankruptcy or lawful dissolution of the Corporation, (ii)
         the occurrence of any event which reduces the number of Shareholders to
         one or (iii) the merger or consolidation of the Corporation with
         another corporation (providing the Corporation is not the surviving
         corporation of such merger or consolidation and provided further that
         the surviving corporation is not owned or controlled, directly or
         indirectly, by the Shareholders). This Agreement may also be terminated
         by an instrument in writing signed by all those who are parties to this
         Agreement at the time of the signing of such instrument.
    
              (g)  Rights after Sale. Any Shareholder who sells all of his Stock
         shall cease to be a party to this Agreement and shall have no further
         rights hereunder.


                                      -14-

              (h)  Joinder of Spouses. The respective spouses of the individual
         Shareholders are fully aware of, understand, and fully consent and
         agree to the provisions of this Agreement and its binding effect upon
         any community or other property interest that they may now or hereafter
         own, and agree that the termination of their marital relationship with
         any Shareholder, for any reason, shall not have the effect of removing
         any Stock of the Corporation otherwise subject to this Agreement from
         the coverage hereof and that their awareness, understanding, consent
         and agreement are evidenced by their execution of this Agreement. If at
         any time hereafter a natural person shall become a party to this
         Agreement, then the spouse of such natural person, by execution of an
         Addendum Agreement in the form of Exhibit A attached hereto pursuant to
         which such Shareholder shall adopt this Agreement, shall evidence and
         acknowledge that such spouse is fully aware of, understands and agrees
         to the provisions of this Agreement and its binding effect upon any
         interest, community or otherwise, such spouse may at any time own in
         any shares of Stock, and by such execution such spouse will agree that
         the termination of marriage to such natural person for any reason shall
         not have the effect of removing any shares of Stock otherwise subject
         to this Agreement from the coverage hereof.

              (i)  Attempted Disposition as Breach. Any attempted Disposition in
         breach of this Agreement shall be null and void. Each party hereto
         acknowledges that a remedy at law for any breach or attempted breach of
         any of Sections 3 through 8 shall be inadequate, agrees that each other
         party hereto shall be entitled to specific performance and injunctive
         and other equitable relief in case of any such breach or attempted
         breach, and further agrees to waive any requirement for the securing or
         posting of any bond in connection with the obtaining of any such
         injunctive or other equitable relief.

              (j)  Addendum Agreement. No Shareholder shall transfer shares of
         Stock, or allow any Disposition of such Shareholder's Stock, and the
         Corporation shall not issue shares of Stock, to any person who is not
         already a party hereto, unless such person and the spouse of such
         person, if applicable, become parties to this Agreement
         contemporaneously with the transfer, Disposition or issuance of such
         shares. Any such person and the spouse of such person shall become
         parties to this Agreement by the execution of an Addendum Agreement in
         substantially the form attached hereto as Exhibit A, to be executed by
         all Shareholders, which Addendum Agreement shall bind such person to,
         and grant them the benefits of, this Agreement as though they were
         original parties hereto.

              (k)  Separability. If any term or provision contained in this
         Agreement is or is hereafter found to be inconsistent with, contrary
         to, or 



                                      -15-
<PAGE>   16
         invalid or unenforceable under any law or official rule, regulation or
         order, this Agreement shall be deemed to be modified accordingly and
         the remaining terms and provisions of this Agreement shall not be
         affected thereby and shall continue in full force and effect.

              (l)  Power of Attorney. Each of the Shareholders hereby
         irrevocably appoints and authorizes the Corporation to execute and
         deliver on his or her behalf the Addendum Agreement described in
         Paragraph 13(j) hereof. The Corporation's authority shall begin on the
         date hereof and shall not terminate on the disability of the respective
         Shareholder.

              (m)  Waiver.  Any waiver to be enforceable must be in writing and
         executed by the party against whom the waiver is sought to be enforced.

              (n)  Drafting.  Both parties hereto acknowledge that each party
         was actively involved in the negotiation and drafting of this Agreement
         and that no law or rule of construction shall be raised or used in
         which the provisions of this Agreement shall be construed in favor or
         against either party hereto because one is deemed to be the author
         thereof.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement in
multiple counterparts, each of which shall be considered an original, but all of
which together shall constitute but one and the same agreement, effective as of
the date and year first above written.
