                             DATED NOVEMBER 27, 1998

                                 EXCHANGE OFFER
                       AN AGGREGATE OF 2,300,000 SHARES OF
               MIDDLE BAY OIL COMPANY, INC. CONVERTIBLE REDEEMABLE
                 SERIES C PREFERRED STOCK FOR PARTNERSHIP UNITS
                       IN ENEX CONSOLIDATED PARTNERS, L.P.
                          (1,102,631 PARTNERSHIP UNITS)

                       EXCHANGE VALUE IN PREFERRED STOCK:
                           $10.43 PER PARTNERSHIP UNIT


This Prospectus (the "Prospectus") is being furnished to the investors
("Investors" or "Unitholders") in Enex Consolidated Partners, L.P., a New Jersey
limited partnership (the "Partnership"), in connection with the offer by Middle
Bay Oil Company, Inc., an Alabama corporation ("Middle Bay") and the controlling
shareholder of Enex Resources Corporation, a Delaware corporation and the
general partner of the Partnership ("Enex" or "General Partner"), to exchange
shares of Series C Convertible Redeemable Preferred Stock, $0.02 par value, of
Middle Bay ("Series C Preferred") for all of the right, title and interest to
units of limited partnership interest in the Partnership ("Partnership Units" or
"Units") held by Investors, at the exchange value outlined below (the "Exchange
Offer"). Each share of Series C Preferred is convertible at any time at the
option of the holder into one share of Middle Bay common stock. The General
Partner of the Partnership is a 79.2% majority-owned subsidiary of Middle Bay,
and the Board of Directors and executive officers of Middle Bay serve as the
Board of Directors and executive officers of the General Partner.

Series C Preferred of Middle Bay is being offered on a proportionate basis to
owners of Partnership Units whereby Unitholders will receive 2.086 shares of
Middle Bay Series C Preferred ($5.00 liquidation value per share) in exchange
for each Unit held (the "Exchange Value Per Unit"). In connection with the
Exchange Offer, a proposal is being submitted to Unitholders in the Partnership
to amend the Partnership Agreement to provide for the transfer of all assets and
liabilities of the Partnership to Middle Bay in exchange for shares of Series C
Preferred and the pro-rata distribution of the Series C Preferred on the basis
of the Exchange Value for each Unit in liquidation of the Partnership. EACH
INVESTOR IN THE PARTNERSHIP WHO TENDERS HIS UNITS WILL, BY THAT TENDER, CONSENT
TO THE PROPOSAL.
<PAGE>   2
Middle Bay is making the Exchange Offer and Proposal for the primary purposes of
consolidating the assets of the Partnership with those of Middle Bay in order to
achieve efficiencies of operation and administration, to increase Middle Bay's
Proved Reserves and borrowing base for further acquisitions of oil and gas
properties, and to afford Unitholders the potential benefit of liquidity in
their investment and an opportunity to participate in Middle Bay's potential
growth as holders of Middle Bay equity securities. See "Reasons for the Exchange
Offer" on page 44.

ADOPTION OF THE PROPOSAL REQUIRES THE CONSENT OF INVESTORS OF THE PARTNERSHIP
HOLDING 60% OR GREATER OF THE PARTNERSHIP UNITS. THE GENERAL PARTNER OF THE
PARTNERSHIP (ENEX) OWNS 620,097 UNITS, COMPRISING 56.24% OF THE 1,102,631 TOTAL
PARTNERSHIP UNITS, AND MIDDLE BAY WILL CAUSE ENEX TO TENDER SUCH UNITS AND
CONSENT TO THE PROPOSAL. IF THE PROPOSAL IS ADOPTED, UNITHOLDERS WILL RECEIVE
THE CONSIDERATION SET FORTH HEREIN, AND THE PARTNERSHIP WILL BE DISSOLVED UPON
CONSUMMATION OF THE EXCHANGE OFFER. ALL OF THE INVESTORS IN THE PARTNERSHIP
(EXCEPT THOSE WHO EXERCISE CERTAIN APPRAISAL AND DISSENTERS' RIGHTS DESCRIBED
BEGINNING ON PAGE 30 OF THIS PROSPECTUS), WHETHER OR NOT THEY TENDER THEIR UNITS
AND THUS VOTE IN FAVOR OF THE EXCHANGE OFFER, WILL RECEIVE THE SAME NUMBER OF
SHARES OF MIDDLE BAY SERIES C PREFERRED AS THEY WOULD HAVE RECEIVED HAD THEY
TENDERED THEIR PARTNERSHIP UNITS, AND THE PARTNERSHIP WILL BE DISSOLVED.

THE EXCHANGE OFFER INVOLVES MATERIAL RISKS THAT SHOULD BE CONSIDERED BY
UNITHOLDERS. SEE "RISK FACTORS AND MATERIAL CONSIDERATIONS" BEGINNING ON PAGE 20
OF THIS PROSPECTUS. IN PARTICULAR, UNITHOLDERS SHOULD CONSIDER THE FOLLOWING
FACTORS:

RISKS REGARDING THE PROPOSAL:

      -     UNITHOLDERS HAVE RECEIVED CASH DISTRIBUTIONS FROM THE PARTNERSHIP
            BASED ON DISTRIBUTABLE CASH GENERATED FROM THE PARTNERSHIP'S
            OPERATIONS. AFTER THE EXCHANGE, DISTRIBUTIONS TO FORMER UNITHOLDERS
            WILL BE IN THE FORM OF CASH DIVIDENDS ON THE SERIES C PREFERRED
            (APPROXIMATELY 10% PER ANNUM ON THE EXCHANGE VALUE, PAYABLE
            SEMI-ANNUALLY). SUCH DIVIDENDS WILL BE SUBSTANTIALLY LESS THAN THE
            HISTORICAL AND CURRENT CASH DISTRIBUTIONS RECEIVED BY UNITHOLDERS
            FROM THE PARTNERSHIP.

      -     THE EXCHANGE VALUE OF THE PARTNERSHIP UNITS IS BASED ON A FAIR
            MARKET VALUE DETERMINATION BY AN INDEPENDENT ENGINEERING FIRM
            EMPLOYED BY THE GENERAL PARTNER; HOWEVER, THERE IS NO ASSURANCE THAT
            THE EXCHANGE VALUE REFLECTS THE VALUE OF THE NET ASSETS OF THE
            PARTNERSHIP IF SUCH WERE SOLD TO AN UNAFFILIATED THIRD PARTY OR
            PARTIES IN AN ARM'S-LENGTH TRANSACTION.
<PAGE>   3
      -     MIDDLE BAY, AS CONTROLLING SHAREHOLDER OF THE GENERAL PARTNER, HAS
            AN INHERENT CONFLICT OF INTEREST IN THE DETERMINATION OF THE
            EXCHANGE VALUE. BOTH THE GENERAL PARTNER AND MIDDLE BAY OWE A
            FIDUCIARY DUTY TO UNITHOLDERS IN THE PARTNERSHIP. IN ADDITION,
            MIDDLE BAY AND ENEX OWE A DUTY TO THEIR RESPECTIVE STOCKHOLDERS.
            FURTHER, MIDDLE BAY EXPECTS TO BENEFIT FROM THE EXCHANGE.

      -     DETERMINATION OF THE EXCHANGE VALUE WAS BASED PRIMARILY ON THE
            ESTIMATED PRESENT VALUE OF THE PARTNERSHIP'S PROVED OIL AND GAS
            RESERVES, WHICH INVOLVES MANY UNCERTAINTIES AND COULD HAVE RESULTED
            IN AN UNDERVALUATION OF PARTNERSHIP UNITS.

      -     PARTNERSHIP UNITS HAVE BEEN PURCHASED BY THE GENERAL PARTNER DURING
            1998 AT PRICES RANGING FROM $11.77 TO $12.44 PER UNIT, WHICH ARE
            GREATER THAN THE EXCHANGE VALUE PER UNIT OF $10.43. MIDDLE BAY
            OBTAINED AN OPINION AS TO THE FAIRNESS OF THE TRANSACTION TO UNIT-
            HOLDERS FROM AN INDEPENDENT INVESTMENT BANKING FIRM; HOWEVER, THAT
            FIRM'S ANALYSIS MADE IN SUPPORT OF THE FAIRNESS OPINION INDICATED A
            FAIR MARKET VALUE RANGE OF THE UNITS WHICH COULD EXCEED THE EXCHANGE
            VALUE.

      -     THE ALTERNATIVES OF CONTINUING THE PARTNERSHIP OR LIQUIDATING ITS
            ASSETS COULD POTENTIALLY BE MORE BENEFICIAL TO UNITHOLDERS THAN THE
            EXCHANGE OFFER.

      -     INVESTORS THAT ARE NOT EXEMPT FROM FEDERAL INCOME TAX ON AN
            INVESTMENT IN THE PARTNERSHIP ARE REQUIRED TO RECOGNIZE GAIN OR LOSS
            ON THE EXCHANGE VALUE RECEIVED BY THEM.

      -     NO INDEPENDENT REPRESENTATIVE WAS ENGAGED TO REPRESENT THE
            UNAFFILIATED INVESTORS IN NEGOTIATING THE TERMS OF THE EXCHANGE
            OFFER, WHICH MAY BE INFERIOR TO THOSE THAT COULD HAVE BEEN
            NEGOTIATED BY AN INDEPENDENT REPRESENTATIVE.

RISKS REGARDING OWNERSHIP OF MIDDLE BAY EQUITY SECURITIES:

      -     OWNERSHIP OF MIDDLE BAY SERIES C PREFERRED MAY INVOLVE GREATER RISK
            THAN AN INVESTMENT IN THE PARTNERSHIP UNITS BECAUSE OF MIDDLE BAY'S
            BROADER OPERATIONS AND ITS USE OF DEBT TO PARTIALLY FINANCE
            ACQUISITIONS.

      -     FUTURE EQUITY OFFERINGS BY MIDDLE BAY COULD POTENTIALLY BE DILUTIVE
            TO THE VALUE OF THE MIDDLE BAY COMMON STOCK INTO WHICH THE SERIES C
            PREFERRED IS CONVERTIBLE.
<PAGE>   4
      -     MIDDLE BAY, AS CONTROLLING SHAREHOLDER OF THE GENERAL PARTNER, HAS
            CONFLICTS OF INTEREST IN DETERMINING THE TERMS OF AND RECOMMENDING
            ACCEPTANCE OF THE PROPOSAL INASMUCH AS BOTH COMPANIES HAVE FIDUCIARY
            DUTIES TO THE UNITHOLDERS, AS WELL AS TO THEIR RESPECTIVE
            SHAREHOLDERS.

In reliance upon the report of H.J. Gruy and Associates, Inc. dated September
23, 1998 (the "Gruy Report") relative to the fair market value of the Proved
Reserves and probable and possible reserves of the Partnership, Middle Bay and
Enex have determined that the Total Exchange Value of all Units is $11,500,000
or $10.43 per Unit. The number of shares of Series C Preferred offered in
exchange for Partnership Units will be determined by dividing the Total Exchange
Value by the $5.00 liquidation value per share of Series C Preferred. Although
Middle Bay has applied to have the Series C Preferred listed for trading on the
NASDAQ Small Cap Stock Market, subject to approval, there is presently no
trading market in the Series C Preferred, and there can be no assurance that a
trading market will develop following the Exchange. On November 25, 1998, the
last reported sales price of the underlying Middle Bay common stock as reported
(Symbol: MBOC) on the NASDAQ Small Cap Stock Market was $3 1/8 per share.

The Exchange Offer may be withdrawn at any time prior to its scheduled
expiration date if Middle Bay determines that a material change affecting the
Partnership or Middle Bay has occurred. The assets and liabilities of the
Partnership, upon approval of the Proposal and adoption of the Exchange Offer,
will be transferred to Middle Bay retroactively effective as of October 1, 1998
(the "Effective Date").

              THE EXCHANGE OFFER EXPIRES AT 5:00 P.M. CENTRAL TIME
                       ON DECEMBER 29, 1998 UNLESS EXTENDED

This Prospectus also constitutes the prospectus of Middle Bay with respect to
the shares of Series C Preferred to be issued as consideration in the Exchange
Offer. Middle Bay has filed a Registration Statement on Form S-4 (together with
any amendments thereto, the "Registration Statement") with the Securities and
Exchange Commission (the "SEC"), of which this Prospectus forms a part.

THE SHARES OF SERIES C PREFERRED TO BE ISSUED IN CONNECTION WITH THE EXCHANGE
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 approximate date on which this Prospectus will first be mailed to the
Investors of the Partnership is November 30, 1998.

                THE DATE OF THIS PROSPECTUS IS NOVEMBER 27, 1998.

                                     SUMMARY

         The following is a brief summary of certain information contained
elsewhere in this Prospectus. This summary is not intended to be a complete
description of the matters covered in this Prospectus and is subject to and
qualified in its entirety by reference to the more detailed information and
financial statements contained elsewhere in this Prospectus, Exhibits hereto and
the documents incorporated herein by reference. Investors are urged to read
carefully the entire Prospectus and Exhibits. See "Glossary" included elsewhere
in this Prospectus for definitions of certain oil and gas terms.

THE EXCHANGE OFFER AND PROPOSAL

         Middle Bay is offering to exchange Series C Preferred for Partnership
Units in the Partnership at the exchange rate outlined below (the "Exchange
Offer"). Investors who tender their Partnership Units will receive 2.086 shares
of Series C Preferred in exchange for each Partnership Unit. Cash will be
exchanged in lieu of any resulting fractional share of Series C Preferred. In
connection with the Exchange Offer, Middle Bay is submitting a Proposal to
Investors in the Partnership to amend the Partnership Agreement to provide for
the transfer of all of the assets and liabilities of the Partnership to Middle
Bay as of the October 1, 1998 Effective Date in exchange for Series C Preferred
and the pro-rata distribution of such consideration in liquidation of the
Partnership. Each Investor who tenders his Partnership Units pursuant to the
Exchange Offer will, by that tender, consent to the Proposal. If the Partnership
adopts the Proposal by the consent of a 60% majority of the Partnership Units,
all Investors in the Partnership (except those who choose to exercise appraisal
or dissenters' rights), whether or not they tendered their Units in the Exchange
Offer, will receive the same amount of Series C Preferred they would have
received had they tendered their Partnership Units. ALTHOUGH CONSUMMATION OF THE
EXCHANGE OFFER FOR THE PARTNERSHIP IS CONDITIONED UPON APPROVAL BY THE
PARTNERSHIP OF THE PROPOSAL, APPROVAL OF THE PROPOSAL AND ADOPTION OF THE
EXCHANGE OFFER IS EXPECTED BECAUSE MIDDLE BAY CONTROLS THE GENERAL PARTNER AND
THUS THE VOTING RIGHTS OF 56.24% OF THE UNITS. See "The Exchange Offer and
Proposal." Unitholders who may be entitled to a fractional share of Series C
Preferred will be paid cash in lieu of the fractional share.

DESCRIPTION OF SERIES C PREFERRED

         The holders of Series C Preferred shares are entitled to receive
cumulative cash dividends in an amount per share of $.50 per annum, payable
semi-annually on March 31st and September 30th of each year (measured by the
fiscal year of Middle Bay). These dividends are payable in preference to and
prior to the payment of any dividend or distribution to any holder of Middle Bay
common stock or other junior security. In the event of a liquidation,
dissolution or winding up of Middle Bay, holders of Series C Preferred shares
will have the right to liquidation preferences in the amount of $5.00 per share
held, plus an amount equal to all dividends accumulated, accrued and unpaid
thereon to the date of final distributions to such holders, before any payment
will be made to holders of Middle Bay common stock or other junior securities of
Middle Bay. The liquidation preferences of the Series C Preferred shares rank on
a parity with the presently issued and outstanding Series B Preferred shares.


                                      - 1 -
<PAGE>   14
         At any time from and after the Effective Date, the holders of Series C
Preferred shares will have the right to convert each share of Series C Preferred
into one share of Middle Bay common stock (as such conversion rate may be
adjusted as a result of any dividend, subdivision, combination or issuance of
Middle Bay common stock). On or after January 1, 2000, Middle Bay may redeem all
or a portion of the Series C Preferred, at its option, at a purchase price of
$5.00 per share, plus an amount equal to all accumulated, accrued and unpaid
dividends, if any, to the date of redemption, subject to the holders' rights to
convert.

         The Series C Preferred is generally nonvoting; however, holders of
Series C Preferred are entitled to vote on any amendment, alteration or appeal
of any provision of Middle Bay's Articles of Incorporation which would adversely
affect any holder's rights and preferences. The issuance of an additional series
of preferred stock will not be deemed to adversely affect the rights and
preferences of the holders of Series C Preferred, so long as any such series of
preferred stock ranks junior to or on a parity with the Series C Preferred.

         Series C Preferred issued in the Exchange will be freely transferable
immediately following issuance; Middle Bay has applied for listing the Series C
Preferred shares for trading on the NASDAQ Small Cap Stock Market, subject to
approval and notice of issuance; however, no trading market presently exists for
the Series C Preferred, and there can be no assurance that a trading market will
develop following consummation of the Exchange. The Exchange Offer may be
withdrawn at the option of Middle Bay if (i) Middle Bay determines, in its sole
discretion, that a material change affecting the Partnership has occurred, or
(ii) Unitholders representing 175,000 or more Units elect to exercise
dissenters' rights. See "The Exchange Offer and Proposal," "Description of
Middle Bay Equity Securities" and "Comparative Rights of Security Holders."

FAIRNESS OF THE EXCHANGE VALUE

         Harris Webb & Garrison, Inc. ("HWG") has rendered its opinion (the
"Fairness Opinion") to Middle Bay and the General Partner that the consideration
to be received by Unitholders based upon the Exchange Value as contemplated by
the Exchange Offer and Proposal is fair from a financial point of view. A copy
of the Fairness Opinion, dated October 15, 1998, is attached hereto as Exhibit
"D" and should be read in its entirety with regard to assumptions made, matters
considered and limitations of the review undertaken by HWG in rendering its
opinion. See "Method of Determining Exchange Value - Fairness Opinion."

COMPARISON OF EXCHANGE VALUE WITH VALUES USED
IN 1997 PARTNERSHIP ROLL-UP

         H.J. Gruy & Associates, Inc. ("Gruy"), an independent petroleum
engineering firm, was engaged by Middle Bay and the General Partner to make a
fair market evaluation of the Partnership's oil and gas reserves as of October
1, 1998. Gruy is the same engineering firm which estimated the oil and gas
reserves for the Partnership and each of the Predecessor Partnerships in
connection with the 1997 consolidation of the Predecessor Partnerships into the
Partnership (the "1997 Roll-up"). Gruy's approach to determining the fair market
value of Proved Reserves for the Partnership for the Exchange Offer was the same
as for each of the partnerships which were consolidated in 1997 to form the
Partnership (the "Predecessor Partnerships")

in connection with the 1997 Roll-up. However, Gruy assigned no fair market value
to the categories of probable and possible reserves for the Predecessor
Partnerships, but did assign a value for those categories of Partnership
reserves for the Exchange Offer. The aggregate fair market value assigned by
Gruy to the Predecessor Partnerships' reserves in 1997 was $13,591,585, while
the present fair market evaluation of the Partnership's reserves is $10,380,000.
To the extent that the fair market evaluation for the Partnership's present
estimated reserves differs materially from the fair market valuation of the
Predecessor Partnerships' reserves in 1997, the primary causes of such changes
are the production and sale of oil and gas production and properties by the
Partnership, the decline in the market prices for oil and gas and changes in
debt and capital due the General Partner over the past 12 months. See "Method of
Determining Exchange Value - Comparison of Exchange Value With Values Used in
1997 Partnership Roll-Up."

SUMMARY RISK FACTORS AND MATERIAL CONSIDERATIONS

         In addition to the information included in this Prospectus, Investors
should carefully consider the following factors in determining whether to accept
the Exchange Offer and consent to the Proposal. The risk factors summarized
below are described in further detail elsewhere in this Prospectus at "Risk
Factors and Material Considerations" beginning on page 19.

         (1)      Risks Associated with the Exchange.

                  Dividends in Lieu of Cash Distributions. The Series C
Preferred is expected to pay cash dividends of 10% ($.50 per Series C Preferred
share) per annum. With respect to its common stock, Middle Bay's policy is to
retain its earnings to support the growth of Middle Bay's business. Accordingly,
the Board of Directors of Middle Bay has never declared cash dividends on its
common stock and does not plan to do so in the foreseeable future. Furthermore,
the terms of Middle Bay's debt agreements prohibit Middle Bay from paying cash
dividends on its common stock. Thus, upon consummation of the Exchange,
Investors who choose to convert the Series C Preferred into common stock would
no longer receive cash distributions, and it is unlikely that cash dividends
will be paid on the Middle Bay common stock at any time in the foreseeable
future.

                  Lack of Arm's-Length Negotiations and Uncertainties in the
Method of Determining the Exchange Value. Although the Exchange Value was
determined by Middle Bay and Enex based upon a fair market evaluation of the
Partnership's Proved Reserves by Gruy dated September 23, 1998 (the "Gruy
Report"), the Exchange Value may not reflect the actual value of the net assets
of the Partnership. The primary assets of the Partnership considered by Gruy
when determining the Exchange Value were the proved oil and gas reserves of the
Partnership (the "Proved Reserves") and the present value of associated future
net cash flows as of October 1, 1998. There are many uncertainties inherent in
estimating quantities of Proved Reserves, and the present value attributed to
the Partnership's Proved Reserves may be less than the discounted future net
cash flows actually received from the Partnership's interest in its oil and gas
properties. In that event, the use of this valuation methodology will have
resulted in an undervaluation of the Partnership Units. See "Method of 
Determining Exchange Value."

                  Federal Income Tax Consequences. Investors that are not exempt
from federal income tax on an investment in the Partnership will be required to
recognize gain or loss on the Exchange Value


                                     - 3 -
<PAGE>   16
received by them. See "Summary of Tax Consequences." To the extent that gain is
recognized, such taxpaying Investors will be required to pay federal income tax,
although they will be receiving Series C Preferred for which a trading market
may not develop. Investors also should consult their individual tax advisors to
determine whether they are subject to any tax under state law.

                  Potential Benefits of Alternatives to the Exchange. The
alternatives to the Exchange Offer are the continuation of the Partnership or
the liquidation of the Partnership's assets and distribution of the liquidation
proceeds to Investors, either of which could potentially be more beneficial to
Investors than the Exchange by avoiding the risks associated with ownership of
Middle Bay Series C Preferred and, in the case of a liquidation of the
Partnership, by providing an immediate cash return to Investors. See "Reasons
for the Exchange Offer - Recommendation of the General Partner" and
"Alternatives to the Exchange."

                  Lack of Independent Representatives for Investors; Fairness
Opinion. No independent representative was selected or hired to represent the
interests of the Investors in negotiating the terms of the Exchange Offer. The
Exchange Value and other terms of the Exchange Offer may therefore be inferior
to those that could have been negotiated by an independent representative.
However, Middle Bay and the General Partner believe the Exchange Offer to be
fair to Unitholders. Middle Bay did retain an independent third party to render
an opinion regarding the fairness of the terms of the Exchange Offer to
Unitholders. The "Fairness Opinion" is summarized under "Fairness Opinion,"
beginning on page 36 of this Prospectus.

                  Conflicts of Interest of Middle Bay and the General Partner.
Middle Bay, as controlling shareholder of the General Partner of the
Partnership, has an inherent conflict of interest in the determination of the
Exchange Value. Both the General Partner and Middle Bay owe a fiduciary duty to
Unitholders in the Partnership. In addition, Middle Bay and Enex owe a duty to
their respective stockholders, and Middle Bay owes a duty to the minority
shareholders of Enex. Middle Bay will benefit from the acquisition of the
Partnership's properties by its receipt of cash flow from the properties and the
addition to its borrowing base of the Proved Reserves of the Partnership which
is expected to facilitate bank financing of future acquisitions. While Middle
Bay believes that it has fulfilled its fiduciary obligations in the
determination of the Exchange Value which is supported, in part, by the Gruy
Report and the Fairness Opinion, no degree of objectivity or professional
competence can eliminate the inherent conflicts of interest. See "Reasons for
the Exchange Offer Fiduciary Duties of Middle Bay and the General Partner" and
"Conflicts of Interest."

                  Other Assets and Liabilities. The method of determining the
Exchange Value takes into account the estimated value of other assets and
liabilities of the Partnership as of September 30, 1998. In calculating the
Exchange Value, the net book value of current assets and liabilities of the
Partnership was derived from the Partnership's unaudited balance sheet as of
September 30, 1998 prepared on an accrual basis. The balance sheet book value of
current assets and liabilities used by Middle Bay in the calculation of fair
market value which was included in the Exchange Value may be higher or lower
than the actual fair market value of those assets and liabilities.

                  Subsequent Events. The Exchange Value will not be adjusted to
reflect changes in the present value of the estimated future net cash flows
attributable to the Proved Reserves of the Partnership after September 23, 1998,
although oil and gas prices in subsequent periods may differ from the prices
used on the date of the reserve reports.

<PAGE>   17
                  No Fractional Shares. No fractional Series C Preferred will be
issued in connection with the Exchange Offer. A Unitholder who would otherwise
be entitled to a fractional share of Series C Preferred will be paid cash in
lieu of such fractional share.

                  Inherent Uncertainties in Estimating Reserves and Future
Revenues. This Prospectus contains estimates of Middle Bay's and the
Partnership's proved oil and gas reserves and future net revenues therefrom. In
order to estimate the reserves, costs and future cash flows, reliance has been
made in part on geological, engineering and economic data furnished by Middle
Bay to Gruy. Although a best efforts attempt has been made to acquire all
pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized.

                  Changes in Form and Nature of Investment Vehicle and Related
Tax Status. The Partnership and its Predecessor Partnerships since inception
have been operated as partnerships under the Internal Revenue Code. Upon
consummation of the Exchange, the assets of the Partnership will be owned and
operated by Middle Bay, a "C" corporation which is subject to federal and state
income taxes. Unlike distributions from the Partnership, dividends of the Series
C Preferred shares are subject to tax at the Middle Bay corporate level and at
the individual shareholder level. Unitholders' rights with regard to
distributions and matters governing control and management of the business and
assets of the Partnership will no longer be determined by the Partnership
Agreement and New Jersey partnership law but will be controlled by the Articles
of Incorporation and Bylaws of Middle Bay and the Alabama Business Corporation
Act. See "Corporate Governance of Middle Bay" and "Comparative Rights of
Security Holders."

         (2)      Risks Associated with Ownership of Middle Bay Equity
Securities.

         In addition to the information included in this Prospectus, Investors
should carefully consider the following factors related to Middle Bay in
determining whether to accept the Exchange Offer. The risk factors summarized
below are described in further detail elsewhere in this Prospectus at "Risk
Factors and Material Considerations."

                  Potential Decline in Market Price of Series C Preferred or
Underlying Common Stock. Access to any trading market which may develop in the
Series C Preferred by exchanging Investors may result in a relatively large
number of shares of Series C Preferred offered for sale immediately after the
Closing Date. This may tend to lower any market price for the Series C
Preferred. Future general stock market conditions, as well as conditions in the
oil and gas industry in general or the effect of such conditions on Middle Bay
in particular, could also adversely affect the market price of the Middle Bay
common stock into which the Series C Preferred is convertible. There can be no
assurance regarding any potential appreciation in the market price of the common
stock. Any decline in the market price of the common stock could lower the
market value of the Series C Preferred and reduce a Unitholder's return on
investment or increase the loss on the Unitholder's original investment.

                  Losses From Middle Bay's Operations. The historical financial
data for Middle Bay reflects a net loss for the year ended December 31, 1997 of
$16,184,052 after incurring a one-time, noncash


                                     - 5 -
<PAGE>   18
impairment charge of $21,147,823 required by Financial Accounting Standard #121
which requires that long-lived assets be reviewed for impairment when events or
changes in circumstances indicate that the carrying value of such assets may not
be recoverable (see "Management's Discussion and Analysis of Financial Condition
and Results of Operations - Fiscal 1997"). Further, Middle Bay's net loss for
the nine-month period ended September 30, 1998 was $2,535,014, or $.32 per share
of common stock. Middle Bay's future ability to maintain its financing
arrangements, produce its oil and gas reserves, service its debt obligations and
pay dividends on the Series C Preferred could be adversely affected by a
continuing lack of profitability.

                  Development of Additional Reserves. Middle Bay's future
success depends significantly upon its ability to find or acquire additional oil
and gas reserves that are economically recoverable. There can be no assurance
that Middle Bay will be able to discover additional commercial quantities of oil
and gas or that Middle Bay will be able to continue to acquire interests in
underdeveloped oil and gas fields and enhance production and reserves therefrom.

                  Retention and Attraction of Key Personnel. Middle Bay depends
to a large extent on the abilities and continued participation of certain key
employees, the loss of whose services could have a material adverse effect on
Middle Bay's business.

         (3)      Risks Related to Oil and Gas Industry.

                  Risks of Oil and Gas Operations. Middle Bay's operations are
subject to all of the risks normally incident to the operation and development
of oil and gas properties and the drilling of oil and gas wells, including
encountering unexpected formations or pressures, blowouts, cratering and fires
and, in horizontal wellbores, the increased risk of mechanical failure and
collapsed holes, the occurrence of any of which could result in personal
injuries, loss of life, environmental damages and other damage to the properties
of Middle Bay or others.

                  Current Oil and Gas Industry Conditions. Prices for oil and
natural gas are subject to wide fluctuation in response to relatively minor
changes in supply of and demand for oil and natural gas, market uncertainty and
a variety of geopolitical and other factors that are beyond the control of
Middle Bay.

                  Regulation. The oil and gas industry is subject to broad and
frequently changing regulations that could adversely affect the operations of
Middle Bay.

                  Competition. The oil and gas exploration and production
business is highly competitive. A large number of companies and individuals
engage in the drilling for and production of oil and gas, and there is a high
degree of competition for desirable oil and gas properties suitable for drilling
and for materials and third-party services essential for their exploration and
development. Many of Middle Bay's competitors have greater financial and other
resources than does Middle Bay.

MIDDLE BAY OIL COMPANY, INC.

         Middle Bay Oil Company, Inc. ("Middle Bay" or the "Company") owns 79.2%
of Enex Resources Corporation ("Enex"), the General Partner of the Partnership.
Middle Bay acquired its controlling ownership of the common stock of Enex in
March, 1998 pursuant to a cash tender offer.

         Middle Bay is primarily engaged in the development and production of
oil and gas properties, and its operations are primarily in the Mid-Continent
and Gulf Coast regions of the contiguous United States. The Company's business
strategy is to seek new reserves principally in areas of low geologic risk and
to exploit underdeveloped existing oil and gas fields, with emphasis on the
following activities:

         -        Increasing production, cash flow and asset value by acquiring
                  Producing Properties with stable production rates, long
                  reserve lives and potential for exploitation and development;

         -        Building on Middle Bay's existing base of operations by
                  concentrating its development activities in its primary
                  operating areas in the Gulf Coast and the Mid-continent
                  Regions;

         -        Acquiring additional properties with potential for
                  developmental drilling to maintain a significant inventory of
                  undeveloped Prospects and to enhance Middle Bay's foundation
                  for future growth;

         -        Serving as operator of its wells to ensure technical
                  performance and reduce costs;

         -        Expanding its relationships with major and large independent
                  oil and gas companies to access their undeveloped properties,
                  seismic data and financial resources;

         -        Managing financial risk and mitigating technical risk by:

                  -    drilling in known productive trends with multi-horizon
                       geologic potential;

                  -    diversifying investment over a large number of wells in
                       Middle Bay's primary operating areas;

                  -    developing properties that provide a balance between
                       short and long reserve lives; and

                  -    keeping a balanced reserve profile between oil and gas;
                       and

         -        Maintaining low general and administrative expenses and
                  increasing economies of scale to reduce per unit operating
                  costs and reserve acquisition costs.

         In the ordinary course of its business, the Company continues to
evaluate acquisition, joint venture and other opportunities that would enable it
to further its business strategy.

         Principal Areas of Activity. The following table shows proved oil and
gas reserves by major field for Middle Bay's largest producing fields at
December 31, 1997. The values represent the present value of estimated future
net cash flows before income taxes, discounted at 10%, assuming unescalated
expenses and

         In 1997, Middle Bay acquired approximately 42,000 net mineral acres,
situated in Terrebonne, Lafourche and St. Mary Parishes in Louisiana pursuant to
a merger agreement with Shore Oil Company. Of the total acreage, 39,769 acres
are non-producing and the remainder is held by production under existing leases.
The nonproducing acreage is located in the following parishes: 20,587 in
Terrebonne (Montegut and


                                     - 8 -
<PAGE>   21
Houma areas), 11,128 acres in Lafourche (Raceland and Valentine areas) and 8,054
acres in St. Mary Parish (Charenton area). The nonproducing acreage currently
under lease and/or option has expiration dates as follows: 17,835 acres in 1998
and 5,722 acres in 2000. As of December 31, 1997, 16,212 acres were not under
lease. Royalty interest in the leases covering the nonproducing minerals ranges
from 20% to 25%. The mineral servitude prescription dates are estimated by
Middle Bay to be as follows: 620 acres prescribed in 1997, 6,226 acres in 1999,
5,286 acres in 2002, 4,145 acres in 2004, 1,121 acres in 2005, 1,145 acres held
in perpetuity and the remaining acreage has prescription interrupted by
production. Effective April 1, 1992, Shore Oil Company sold the production
rights under tracts producing at that time and does not receive royalty income
from the sale of oil or gas on those tracts. Over 80% of the nonproducing
minerals have been covered by 3-D seismic shot by third parties and provided to
Middle Bay at no cost. During the period July 1, 1997 through December 31, 1997,
Middle Bay received approximately $975,000 in lease bonus, delay rental and
seismic option income on the acreage. Lee Keeling and Associates, Inc., an
independent oil and gas engineering firm valued the acreage as of June 30, 1997
at $3,627,000. See "Experts." One unsuccessful exploratory well in Lafourche
Parish, the Shore Oil Company #1, was drilled on the fee mineral acreage in 1997
and abandoned in February, 1998. In Terrebonne Parish, two unsuccessful
exploratory wells, the Middle Bay Oil Co. #1 and Shore Oil Co. #1, were
abandoned in February and May, 1998, respectively. As of September 30, 1998, an
exploratory well, the Shore Oil Company #1, which was drilled in St. Mary
Parish, Louisiana, has been successfully completed and is awaiting installation
of production facilities. A second exploratory well, the Middle Bay Oil Co. #1,
was drilling in St. Mary Parish, Louisiana at September 30, 1998.

         Productive Wells and Acreage. The following table depicts the number of
gross and net producing wells and related Developed and Undeveloped Acreage in
which Middle Bay owned an interest for the period ended December 31, 1997.
Undeveloped Acreage is oil and gas acreage (including, in certain instances,
rights in one or more horizons which may be penetrated by existing well bores,
but which have not been tested) to which Proved Reserves have not been assigned
by independent petroleum engineers.

         Middle Bay's net Developed Acreage is located primarily in Oklahoma,
Texas, Louisiana, Alabama, New Mexico and Kansas. Middle Bay's net Undeveloped
Acreage is located primarily in Kansas.

         Excluded from the acreage data are approximately 44,041 net mineral
acres owned by Middle Bay, all of which are considered to have potential for oil
and gas exploration.

         Middle Bay was incorporated in Alabama in 1992. Its principal executive
offices are located at 1221 Lamar Street, Suite 1020, Houston, Texas 77010, and
its telephone number is (713) 759-6808.

ENEX CONSOLIDATED PARTNERS, L.P.

         Enex Consolidated Partners, L.P. (the "Partnership") was formed under
New Jersey Uniform Limited Partnership Law (1976) on June 30, 1997 from the
combination of thirty-four Enex Oil and Gas limited partnerships, consisting of
Enex Program I Partners, L.P., four partnerships in Enex Oil & Gas Income
Program II, eight partnerships in Enex Oil & Gas Income Program III, six
partnerships in Enex Oil & Gas Income Program IV, five partnerships in Enex Oil
& Gas Income Program V, Enex Oil & Gas Income Program VI - Series 1, L.P., three
partnerships in Enex Income and Retirement Fund, three partnerships in Enex
88-89 Income and Retirement Fund, and three partnerships in Enex 90-91 Income
and Retirement Fund (collectively, the "Predecessor Partnerships"). The General
Partner of the Partnership is Enex Resources Corporation, a Delaware corporation
which is a 79.2% owned subsidiary of Middle Bay. The Partnership and the General
Partner maintain their principal executive offices at the principal offices of
Middle Bay, 1221 Lamar Street, Suite 1020, Houston, Texas 77010. The telephone
number is (713) 759-6808.

         The Predecessor Partnerships were consolidated into the Partnership
based on fair market evaluations of the oil and gas reserves of each Predecessor
Partnership prepared by Gruy, and Enex has managed the Partnership as General
Partner since that date. Each of the Predecessor Partnership's assets consisted
primarily of interests in producing wells and, to a lesser extent, interests in
properties with proved undeveloped acreage. Certain of the principal objectives
of the consolidation included (i) anticipated reduction of overhead and
operating expenses, (ii) simplified managerial and administrative requirements,
(iii) reduction of risk due to diversification of assets, and (iv) an expanded
reserve base, all with a view toward maximizing income distributions to
Unitholders. Certain of the Predecessor Partnerships held interests in
properties with proved undeveloped reserves, and a further objective of the
Partnership was to complete the development of those properties. The Partnership
has now completed its drilling operations and acquisitions, and the General
Partner and Middle Bay believe that the objectives of the consolidation of the
Predecessor Partnerships have been substantially achieved.

         The Partnership is now engaged in the oil and gas business through the
ownership of various interests in producing oil and gas properties, as described
elsewhere herein. The Partnership has not engaged in significant drilling
activities except as an incidental part of the management of producing
properties or with a view toward enhancing the value of producing properties.
The Partnership does not engage in exploratory drilling. The expenses of
drilling, completing and equipping and operating development wells are allocated
approximately 96% to the limited partners and 4% to the General Partner.

         The primary investment objectives of the Partnership and its
Predecessor Partnerships were to acquire and hold nonworking interests in oil
and gas properties that (i) did not subject the Partnership to the obligations
inherent in the operations of oil and gas properties, (ii) entitled the
Partnership to revenues from


                                     - 10 -
<PAGE>   23
sales of oil and gas, net of certain costs and expenses, which would result in
regular cash distributions to Unitholders, and (iii) represented proved oil and
gas reserves, the future production of which would afford protection against
future inflationary increases in oil and gas prices. Although the Partnership
has been operating for less than 18 months since the 1997 Roll-up, Middle Bay
and the General Partner believe these objectives have been substantially met
inasmuch as Unitholders have received cash distributions of approximately $5.85
per Unit since the 1997 Roll-up.


GENERAL BACKGROUND INFORMATION LEADING UP TO THE EXCHANGE OFFER

         Enex was contacted in January, 1998 by management of Middle Bay, a
publicly-owned oil and gas company whose shares are traded on the NASDAQ Small
Cap Stock Market (symbol: MBOC). Middle Bay was seeking potential acquisitions
to broaden its business operations and increase its proved reserves of oil and
gas. Middle Bay and Enex were not affiliated at the time, and there had been no
material prior contacts between the two companies.

         Negotiations between Enex and Middle Bay resulted in Middle Bay
agreeing to make a cash tender offer for all the outstanding shares of common
stock of Enex for $15.00 per share, and Enex's then Board of Directors agreed,
subject to successful completion of the tender offer, to resign and appoint the
Middle Bay directors as directors of Enex. The tender offer commenced in
February, 1998 and was successfully closed in March, 1998, with Middle Bay
acquiring 79.2% of the outstanding common stock of Enex. Since that time, Middle
Bay has controlled and managed Enex as a majority-owned subsidiary, with the
Enex Board of Directors and principal executive officers being the persons who
hold corresponding positions at Middle Bay.

         Both prior and subsequent to the acquisition of Enex by Middle Bay,
Enex has received inquiries and concerns from Investors regarding anticipated
production declines and reductions of cash distributions to Unitholders and
determined that the Partnership had reached the stage in its production history
where consideration of the Exchange Offer became appropriate. That determination
was based on the following factors:

                  Production Declines. Since 1993, the Partnership's
consolidated oil and gas production volumes have declined from peak levels
reached in 1992. Production volumes are expected to decline further in
subsequent periods due to ongoing depletion of the Partnership's wells. The
decline in production rates due to depletion of reserves is neither unusual nor
unexpected in the oil and gas industry.

                  Middle Bay's Decision to Acquire the Partnership's Properties.
Since Middle Bay's acquisition of Enex, the Company has analyzed the
Partnership's properties and now believes it is a natural acquisition candidate
for various reasons, including Middle Bay's (i) interest in reducing the
overhead expense involved in administration of the Partnership by Enex; (ii)
greater diversification and capital resources enabling Middle Bay to fund
contingent liabilities and other expenses necessary for the continued operation
of the Partnership's properties; (iii) interest in assisting the General Partner
in responding to Investors' concerns about the future prospects of the
Partnership; and (iv) anticipated benefits of broadening its reserve and
borrowing bases by acquiring the Partnership's properties.

<PAGE>   24
                  Middle Bay's Decision to Offer Series C Preferred. Middle Bay
initially considered offering shares of Middle Bay common stock in exchange for
the Partnership's Units; however, for various reasons, including the substantial
decline in the market value of Middle Bay common stock in 1998 and the
consideration of the expectations of Unitholders for continued cash
distributions on their investments in the Partnership, Middle Bay determined to
offer Series C Preferred stock which it believes affords Unitholders the
opportunity for continued income from cash dividends plus the added advantage of
possible appreciation in value if the underlying Middle Bay common stock into
which the Series C Preferred is convertible increases in market value.

ALTERNATIVES TO THE EXCHANGE

         Although Middle Bay and Enex have considered the continuation of the
Partnership or liquidation of the Partnership as potential alternatives to the
Exchange Offer, these alternatives were rejected for various reasons, including
the following:

                  Liquidation. Although liquidation would provide an immediate
cash return to the limited partners and would avoid the risks associated with
the ownership of Middle Bay shares, based on its experience in the oil and gas
industry, the General Partner determined that a liquidation of the Partnership
would likely result in lower cash value to the limited partners than the value
represented by the Series C Preferred. This is because third-party purchasers of
oil and gas properties may pay less than the net present value, discounted at
10%, of the anticipated cash flows of a property's proved oil and gas reserves,
further adjusted for risks associated with different types of reserves and other
factors, and the administrative and overhead expenses incurred during the period
of liquidation would further reduce the cash available to the limited partners.
The market prices of Middle Bay Series C Preferred (if any) and Middle Bay
common stock from time to time may reflect additional value associated with
Middle Bay's success (of which there can be no assurance) as a growth company in
the oil and gas business.

                  Lack of Partnership Resources and Declining Reserves.
Continuation of the Partnership, while avoiding the risks associated with the
Exchange Offer and the discontinuance of cash distributions, would result in
declining operating results and distribution rates for the Partnership because:
(i) reserves will be depleted in the ordinary course from ongoing production,
(ii) general and administrative expenses will remain the same, regardless of the
operating results of the Partnership, and (iii) the Partnership would have to
incur the cost of plugging and abandoning Partnership wells when they become
uneconomic or any future sale of the Partnership's wells would be at a price
which would reflect the anticipated costs of such plugging and abandonment
expenses.

                  Management's Conclusions Regarding Liquidation Value of the
Partnership at Comparable Values. Middle Bay and Enex have concluded that, while
an asset sale in liquidation might generate limited third-party interest, a sale
of the assets of the Partnership would not provide immediate cash returns to
Investors in excess of the liquidation value of the Partnership and would likely
result in valuations by a third-party bidder or bidders below the Exchange Value
of the Partnership Units. Middle Bay has engaged Gruy to provide an independent
analysis of the current liquidation value of the Partnership. Results of that
liquidation analysis reflect a liquidation value for the Partnership estimated
at $8.96 per Unit, or approximately 14% less than the Exchange Value. In view of
the uncertainties inherent in the General


                                     - 12 -
<PAGE>   25
Partner's analysis of the value, there can be no assurance that obtaining
additional bids for an arm's-length sale of the Partnership's assets would not
result in a valuation that would be comparable to or higher than the Exchange
Value, while also avoiding the risks associated with ownership of the Series C
Preferred.

REASONS FOR THE EXCHANGE OFFER; RECOMMENDATIONS OF THE
GENERAL PARTNER AND MIDDLE BAY

         Although the Partnership has existed for less than 18 months since the
1997 consolidation of the Predecessor Partnerships, based on the Gruy Report and
supported by the Fairness Opinion, Middle Bay and the General Partner believe
that the Exchange Offer is fair to and in the best interests of the Partnership
and its Unitholders and recommends that Unitholders consent to the Proposal and
accept the Exchange Offer. See "Background of the Exchange Offer." The
recommendation is made in light of the fiduciary duties owed by the General
Partner and Middle Bay to the Unitholders and is based on a number of factors
discussed in this Prospectus, including benefits of the Exchange to Middle Bay
which involve inherent conflicts of interest. See "Reasons for the Exchange
Offer." If the Exchange is not consummated, the Partnership will continue to
operate its properties, and the General Partner will review alternatives that
may become available from time to time regarding the sale of the Partnership's
assets.

FIDUCIARY DUTIES OF THE GENERAL PARTNER AND MIDDLE BAY

         Both the General Partner and Middle Bay owe a fiduciary duty to
Unitholders in the Partnership. In addition, Middle Bay and Enex owe a duty to
their respective stockholders, and Middle Bay owes a duty to the minority
shareholders of Enex. Middle Bay's and Enex's fiduciary duties to Unitholders
include legal responsibilities of loyalty, care and good faith. Neither Enex, as
the General Partner of the Partnership, nor Middle Bay, as the parent of Enex,
may profit by any conduct or transaction in contravention of their fiduciary
obligations to the Investors.

ACCOUNTING TREATMENT

         The Exchange will be accounted for as a purchase by Middle Bay.
Accordingly, the purchase price will be allocated to assets and liabilities
based on their estimated values as of the date of acquisition.

BUSINESS OF MIDDLE BAY AND THE PARTNERSHIP AFTER CONSUMMATION OF THE EXCHANGE

         Middle Bay is an independent oil and gas company engaged in the
acquisition of producing properties and the exploration, development and
production of oil and gas in the contiguous United States, primarily in the
Mid-Continent and Gulf Coast regions. Upon consummation of the Exchange, Middle
Bay will operate the acquired Partnership assets as it operates its oil and gas
properties or may sell such assets to third parties at any time. See "Background
of the Exchange Offer."

COMPARATIVE RIGHTS OF SECURITY HOLDERS


                                     - 13 -
<PAGE>   26
         For a comparison of the rights of Middle Bay stockholders under Alabama
law and Middle Bay's Certificate of Incorporation and Bylaws with the rights of
the partners of the Partnership under New Jersey law and the Partnership
Agreement, see "Comparative Rights of Security Holders."

LIMITED APPRAISAL/DISSENTERS' RIGHTS

         Unitholders who do not vote in favor of or who oppose the Proposal will
have certain appraisal or dissenters' rights. Unitholders who elect to exercise
their appraisal rights will have the option to receive cash in lieu of the
Series C Preferred based on the liquidation value of the Partnership's assets
determined in accordance with the Gruy Report, as adjusted in accordance with
the Partnership Agreement. Such rights are not required by New Jersey
partnership law, and the appraisal and limited dissenters' rights afforded
Unitholders are those provided by the Partnership Agreement.

         Investors residing in California will be afforded the option to elect
limited dissenters' rights in accordance with the requirements for roll-up
transactions under the California Code. By voting against the Proposal,
Investors in the State of California who choose to exercise their California
dissenters' rights will receive the cash equivalent of the Exchange Value of
their interests. If that cash amount is greater than the liquidation value of
the Units, dissenting California Investors will receive more cash than they
would otherwise receive by electing appraisal rights under the Partnership
Agreement. California Investors hold less than 1% of the interests in the
Partnership, and the impact of the exercise of appraisal rights or dissenters'
rights under California law is not likely to materially affect the number of
shares of Series C Preferred issued or cash paid pursuant to appraisal or
dissenters' rights by Middle Bay in connection with the Exchange Offer.

RIGHT TO INSPECT AND COPY PARTNERSHIP RECORDS

         A Unitholder has the right to inspect and copy a list of the names and
addresses of all other Unitholders of the Partnership at the principal office of
the Partnership (which is the office of the General Partner and Middle Bay in
Houston, Texas) during normal business hours. On request, a copy of such list,
under certain circumstances, will be furnished to any Unitholder upon payment of
reasonable reproduction and mailing costs.

RESALES OF MIDDLE BAY SERIES C PREFERRED; NASDAQ SMALL CAP STOCK MARKET LISTING

         The shares of Middle Bay Series C Preferred (including the underlying
shares of common stock into which the Series C Preferred is convertible) that
will be issued to Unitholders in connection with the Exchange and upon
liquidation of the Partnership have been registered under the Securities Act.
Application has been made by Middle Bay for listing of the Series C Preferred on
the NASDAQ Small Cap Stock Market subject to notice of issuance. All shares of
Series C Preferred received by Unitholders will be freely tradable by those
Investors to the extent that any trading market develops in the Series C
Preferred. Investors who choose to convert the Series C Preferred into shares of
Middle Bay common stock will receive freely tradeable shares of common stock.
Middle Bay's common stock is traded on the NASDAQ Small Cap Stock Market
(symbol: MBOC).

MATERIAL ADVANTAGES AND DISADVANTAGES OF THE EXCHANGE AND PROPOSAL

         In considering the Exchange, Middle Bay and the General Partner, took
into account various advantages and disadvantages of the Exchange to the
Partnership and its Investors. The advantages considered included:

         (a)      The total consideration to be received by Unitholders
                  represents the fair market value of all assets of the
                  Partnership as supported by the Gruy Report and the Fairness
                  Opinion;

         (b)      Middle Bay's historical growth in Proved Reserves and oil and
                  gas production and its future business prospects;

         (c)      Middle Bay's assumption of all liabilities of the Partnership,
                  including any contingent or other liabilities not presently
                  known to the Partnership;

         (d)      The consideration to be received by the Partnership in
                  connection with the Exchange represents consideration to
                  Unitholders in excess of that which could be expected from
                  continued cash distributions;

         (e)      Investors will receive the benefit of any future growth in the
                  value of their equity interest in Middle Bay rather than
                  receiving cash distributions from the Partnership, which are
                  likely to decrease rapidly as the remaining oil and natural
                  gas reserves of the Partnership are depleted; and

         (f)      Liquidity of the common stock of Middle Bay underlying the
                  Series C Preferred and the potential liquidity of the Series C
                  Preferred compared to the lack of liquidity of the Partnership
                  Units.

         The General Partner also considered certain disadvantages that
included:

         (a)      The possibility that the price of oil and/or gas could
                  increase, thereby increasing the value of the Proved Reserves
                  of the Partnership, which could have a more direct benefit to
                  Unitholders if owned by the Partnership rather than Middle
                  Bay;

         (b)      Although the Series C Preferred is expected to pay cash
                  dividends semi-annually at the rate of 10% per annum ($.50 per
                  Series C Preferred share per year), Middle Bay is restricted
                  under certain credit agreements from paying cash dividends on
                  its common stock, and Unitholders could continue to receive
                  cash distributions from the Partnership which would be in
                  excess of the dividend income payable on the Series C
                  Preferred shares per year;

         (c)      Tax consequences to Unitholders in connection with the
                  Exchange and liquidation of the Partnership;


                                     - 15 -
<PAGE>   28
         (d)      The possibility that the reserve estimates for the Partnership
                  could be undervalued; and

         (e)      Risks associated with the future market value of Middle Bay
                  Series C Preferred or the underlying common stock.

See "Reasons for the Exchange Offer." For other relevant factors, see also "Risk
Factors and Material Considerations."

METHOD OF DETERMINING EXCHANGE VALUE FOR THE PARTNERSHIP

         Components of the Exchange Value. The Total Exchange Value represents
the estimated fair market value of the Partnership's Proved Reserves as
determined by the Gruy Report and other net assets, including probable and
possible reserves and general intangibles, as determined by Middle Bay and Enex.
These components represent all of the assets and liabilities of the Partnership
and were determined by Gruy, Middle Bay and Enex as of October 1, 1998, the
Economic Effective Date.

         Neither Middle Bay nor Enex instructed Gruy as to pricing, cost or
other economic parameters or methods or the assessment of reserve
characteristics, nor did either company limit the scope of Gruy's investigation
for purposes of preparing the fair market value appraisal. Enex provided Gruy
with basic evaluation data for its use in determining the Partnership's Proved
Reserves and their value. Gruy prepared its own reserve estimates of the
Partnership's properties. Neither Middle Bay nor Enex directed Gruy as to the
amount of consideration to be paid to the Partnership for its property interests
nor provided any information to Gruy on amounts to be paid to Unitholders. The
amount of consideration to be paid was determined by Middle Bay's Board of
Directors based upon Gruy's estimates of the fair market value of those
interests. Gruy did not opine on the fairness of the transaction to Unitholders;
however, Middle Bay acquired a separate report or opinion regarding the fairness
to Unitholders of the price at which the Partnership's assets will be sold to
Middle Bay if the Proposal is approved by Unitholders.

         The following unaudited table sets forth (i) the components of the
Exchange Value of the Units and (ii) the Exchange Value Per Unit held by an
Investor. This information was compiled by Gruy and Enex from the Partnership's
financial and property records for the year ended December 31, 1997 and such
records for the nine months ended September 30, 1998:

         value report dated September 23, 1998 for the Partnership as of that
         date issued by H.J. Gruy and Associates, Inc., independent petroleum
         engineers.

(5)      Obtained by dividing the Total Exchange Value by the Series C Preferred
         liquidation value of $5.00 per share.

         Proved Reserves. Proved Reserves of the Partnership and the estimated
future net cash flows attributable thereto were derived from the fair market
value report dated September 23, 1998 for the Partnership prepared by Gruy (the
"Gruy Report"). The reserve estimates were prepared in accordance with SEC
regulations concerning Proved Reserves, with estimated future net cash flows
from Proved Reserves based on prices as of September 23, 1998, except that
certain escalations of prices and costs were made over the estimated life of the
reserves and discounted at 10% per annum. In addition, Gruy estimated the fair
market value of probable and possible reserves. A suitable risk adjustment
factor was applied during the evaluation process utilized by Gruy to obtain the
estimated future net cash flows from the Proved Reserves of the Partnership to
account for uncertainties inherent in projecting future production rates, and,
except for price and cost escalation assumptions used by Gruy, no adjustment was
made to take into account fluctuations in oil and gas prices after October 1,
1998.

         General Intangibles. In determining the value attributed to general
intangibles, Middle Bay and Enex evaluated the success to date of the
Partnership, total consideration paid to date to Investors and the value to
Middle Bay of dissolving and liquidating the Partnership so that Middle Bay can
focus on its current operations and reduce the administrative burdens associated
with operating the Partnership.

         From inception through October, 1998, the Partnership has made cash
distributions to Unitholders aggregating $6,455,865, or approximately $5.85 per
Unit. Assuming that an Investor in the Partnership elects to hold his or her
shares of Series C Preferred and the aggregate market price of the shares of
Series C Preferred received per Unit (if a trading market develops) remains at
or above the Exchange Value per Unit of $10.43, Middle Bay believes that
Unitholders will have received consideration in the form of cash distributions
and Series C Preferred (valued at $5.00 per share) of approximately 163% of the
initial investment in the Partnership since its consolidation as of July, 1997,
without regard to any tax benefits received by the participants. Middle Bay
believes that Unitholders would not receive any value for the general
intangibles in any alternative to the Exchange.

         Comparison of Valuation for Purposes of the Exchange Offer With
Valuation Performed for the 1997 Roll-up. Gruy was engaged by Middle Bay and the
General Partner to make a fair market evaluation of the Partnership's oil and
gas reserves as of October 1, 1998. Gruy is the same engineering firm which
estimated the oil and gas reserves for the Partnership and each of the
Predecessor Partnerships in connection with the 1997 consolidation of the
Predecessor Partnerships into the Partnership (the "1997 Roll-up"). Gruy's


                                     - 17 -

approach to determining the fair market value of Proved Reserves for the
Partnership for the Exchange Offer was the same as for each of the partnerships
which were consolidated in 1997 to form the Partnership in connection with the
1997 Roll-up. However, Gruy assigned no fair market value to the categories of
probable and possible reserves for the Predecessor Partnerships, but did assign
a value for those categories of Partnership reserves for the Exchange Offer. The
aggregate fair market value assigned by Gruy to the Predecessor Partnerships'
reserves in 1997 was $13,591,585, while the present fair market evaluation of
the Partnership's reserves is $10,380,000. To the extent that the fair market
evaluation for the Partnership's present estimated reserves differs materially
from the fair market valuation of the Predecessor Partnerships' reserves in
1997, the primary causes of such changes are the production and sale of oil and
gas production and properties by the Partnership, the decline in the market
prices for oil and gas and changes in debt and capital due the General Partner
over the past 12 months.

         Uncertainties Inherent in Valuation Methodology. There are numerous
uncertainties inherent in estimating quantities and production rates of
hydrocarbons. Estimates of the Partnership's Proved Reserves by independent
petroleum engineers other than Gruy could result in higher or lower valuations
than those determined by Gruy. The Exchange Value may not reflect the value of
the Units or the value of the properties attributable to the Units if sold to an
unaffiliated third party or parties in an arm's-length transaction.

FAIRNESS OPINION

         Harris Webb & Garrison, Inc. ("HWG") has rendered its opinion (the
"Fairness Opinion") to Middle Bay and the General Partner that the consideration
to be received by Unitholders based upon the Exchange Value as contemplated by
the Exchange Offer and Proposal is fair from a financial point of view. A copy
of the Fairness Opinion, dated October 15, 1998, is attached hereto as Exhibit
"D" and should be read in its entirety with regard to assumptions made, matters
considered and limitations of the review undertaken by HWG in rendering its
opinion. See "Method of Determining Exchange Value - Fairness Opinion."

CONSENT PROCEDURES

         To tender Partnership Units in exchange for Series C Preferred at the
Exchange Rate and thereby consent to the Proposal, each Unitholder should
complete and sign the Letter of Transmittal accompanying this Prospectus (a form
of which is included as Exhibit "C") and return it to the Exchange Agent during
the 20-business-day period ending at 5:00 p.m. Central Time on December 29,
1998 (the "Expiration Date"). The Expiration Date may be extended for up to an
additional ten-day period, although no extension is presently contemplated.
Middle Bay will not accept tenders of less than all of the Partnership Units
held by a Unitholder. Tenders of Units and consents to the Proposal may be
withdrawn upon written notice to American Securities Transfer & Trust, Inc., 938
Quail Street, Suite 101, Lakewood, CO 80215, Attention: Proxy Department,
received at any time prior to the Expiration Date. See "Consent Procedures,"
page 52.

SUMMARY OF TAX CONSEQUENCES OF THE EXCHANGE

         Upon consummation of the Exchange, Unitholders will realize gain in an
amount equal to the excess of the fair market value of the Series C Preferred
received by them over their respective bases in the Partnership Units they hold.
If a Unitholder's Unit has a tax basis greater than the fair market value of the
Series C Preferred received, such Unitholder would realize a loss for tax
purposes.

         Assuming the Investor has held his Interest for more than one year and
assuming his Units have not been held for sale in the ordinary course of the
Investor's trade or business, any gain or loss realized upon the transfer of the
Partnership Units will be taxed as long-term capital gain or loss, except to the
extent that the consideration received is attributable to his allocable share of
inventory items and unrealized receivables (including depreciation recapture and
excess intangible drilling and development costs) of the Partnership. The
portion of any gain attributable to these items will be taxed to the Investor as
ordinary income.

         Investors should read the more detailed discussion of the federal
income tax consequences contained in "Certain Federal Tax Consequences" and are
also urged to consult with their own tax advisors with respect to the tax
consequences to them of the transaction, including the application of state,
local and foreign tax laws.

CONDITIONS TO THE EXCHANGE

         The Exchange Offer is expected to be consummated on the Closing Date,
which shall be no more than five days following the Expiration Date, as
extended. The Exchange Offer to the Partnership is conditioned upon consent of
60% of the Units to the Proposal and the absence of any material adverse
development affecting the Partnership or Middle Bay, as determined by Middle Bay
in its sole discretion. On the Closing Date, subject to satisfaction of these
conditions, Middle Bay intends to accept all Units validly tendered and not
withdrawn pursuant to the Exchange Offer.

REGULATORY APPROVALS

         Upon effectiveness of the registration statement of which this
prospectus constitutes a part, federal or state regulatory approval is required
in connection with the Exchange Offer or the adoption of the Proposal by the
Partnership.

CERTAIN TRANSACTIONS BETWEEN THE PARTNERSHIP, ENEX AND MIDDLE BAY

         Enex, as General Partner and as a Unitholder of the Partnership, has
received $3,574,810 in total distributions from the Partnership since its
formation in 1997. These distributions included $3,403,404 attributable to
Enex's interest as a Unitholder and $171,406 attributable to its general
partnership interest. Middle Bay, as owner of 79.2% of Enex since March 27,
1998, benefits indirectly from the Partnership's distributions to Enex. Since
July 1997, on two occasions Enex has purchased for cash a total of 39,826 Units
from various Unitholders at prices ranging from $11.77 to $12.44 per Unit. These
purchases by Enex of Units have been made in accordance with the presentment and
valuation procedures set forth in Article 6 of the Partnership

                                     - 19 -
<PAGE>   32
Agreement ("Right to Present Units for Purchase"). Under the procedures outlined
in such Article 6, the General Partner determined the purchase price of the
previously-acquired Units based upon an independent expert's estimate as of the
previous December 31st of the discounted present worth of future net revenues
attributable to the Partnership's interest in Proved Developed Reserves and
Proved Undeveloped Reserves, plus the value of other assets of the Partnership,
less liabilities attributable to the capital accounts of the Unitholders (the 
"Presentment Price"). Summaries of the calculations used to determine the 
Presentment Prices as of July 1, 1997 and as of January 1, 1998 are as follows:

Enex and Middle Bay believe that the Exchange Value of $10.43 per Unit is a fair
value in relation to the prices paid in previous purchases of Units by the
General Partner inasmuch as the Exchange Value was determined in a manner
consistent with the foregoing procedures supported by the Gruy Report and the
Fairness Opinion. The reserve reports prepared by Gruy for the July 1, 1997
Presentment Price determination were the same reports used in connection with
the 1997 Roll-up (see "Comparison of Exchange Value With Values Used in 1997
Partnership Rollup"). Gruy used the same methodology and approach for its
reserve report used by the Partnership for the January 1, 1998 Presentment Price
determination. 


                    RISK FACTORS AND MATERIAL CONSIDERATIONS

         In addition to the material contained elsewhere herein, the following
factors should be carefully considered.

RISKS RELATED TO THE EXCHANGE OFFER

                  Dividends in Lieu of Cash Distributions. The Exchange will
result in the Unitholders holding shares of Series C Preferred of Middle Bay.
The Series C Preferred is expected to pay cash dividends of $.50 per Preferred
Share which, based on the Exchange Value of 2.086 Preferred Shares per Unit,
result in annual dividends of $1.04 per Unit (10% per annum on the Exchange
Value), payable semi-annually. Middle Bay has paid no cash dividends on its
common stock and does not anticipate paying cash dividends on its common stock
in the foreseeable future. The cash distributions paid by the Partnership were
$3.07 per Unit for 1997 and $.85 per Unit for the quarter ended March 31, 1998,
$.75 per Unit for the quarter ended June 30, 1998, and $1.18 per Unit for the
quarter ended September 30, 1998. Despite the reduction in cash distributions to
the Partners in connection with the Exchange, Middle Bay believes that if the
Partnership were to continue operations, the cash distributions that Investors
would receive from the Partnership would rapidly decline as the reserves of the
Partnership are depleted.

                  Lack of Arm's-Length Negotiations to Determine Value of
Partnership Units. The Exchange Value of the Partnership Units were determined
by Middle Bay based on the Gruy Report which contains a fair market value
determination based, in part, on the estimated present value of the
Partnership's Proved Reserves and a valuation of the general intangibles of the
Partnership by Middle Bay (as described herein) and, as a result of Middle Bay's
inherent conflict of interests and various uncertainties involved in estimating
reserve quantities and values, may not reflect the value of the oil and gas
properties and other assets of the Partnership if such assets were sold to an
unaffiliated third party in an arm's-length transaction. See "Uncertainties in
the Method of Determining the Exchange Value" and "Valuation Conflict of
Interest" below. While Middle Bay believes that the methodology employed in
determining the Exchange Value is fair to Unitholders, resulting in valuations
that exceed the estimated liquidation value of the Partnership, the liquidation
value was determined by Middle Bay in reliance upon the Gruy Report.


                                     - 20 -
<PAGE>   33
                  Risks Relating to Certain Federal Income Tax Considerations.
Upon consummation of the Exchange, Investors will recognize gain in the amount
of and to the extent that the fair market value of the Series C Preferred
received by them exceeds their respective bases in the Partnership Units they
hold. Further, the Internal Revenue Service may seek to recharacterize the
transaction as a transfer of assets by the Partnership in exchange for Series C
Preferred and subsequent liquidation of the Partnership and distribution of its
remaining assets. Such recharacterization of the transaction may adversely
affect the characterization of income recognized by Investors upon consummation
of the Exchange. In addition, under such circumstances, the tax consequences
realized by an Investor consenting to the Exchange Offer may differ from that
realized by Investors who do not participate in the Exchange but rather receive
Series C Preferred upon liquidation of the Partnership.

                  Potential Benefits of Alternatives to the Exchange. Instead of
proposing the Exchange, Middle Bay, as controlling shareholder of the General
Partner, could instead continue to operate the Partnership or, with the approval
of Unitholders of the Partnership, seek to liquidate the Partnership's assets
and distribute the liquidation proceeds in accordance with the provisions of the
Partnership Agreement, enabling Investors to reinvest proceeds from the asset
sales in the case of a liquidation and avoid the market risks associated with
the ownership of Middle Bay Series C Preferred to be received in the Exchange.
Both alternatives were rejected by Middle Bay based on its analysis of their
comparative results and values. Middle Bay believes that continuation of the
Partnership would result in substantial additional reductions in the cash
distribution rates for the Partnership due primarily to expected production
declines from depletion of reserves. Middle Bay's analysis of continuing the
Partnership in light of these factors, based on average oil and gas prices
received in 1998 and reserve data as of October 1, 1998, reflects declines in
projected annual distribution rates per Unit from $3.07 in 1997 to $3.22 in
1998, $1.33 in 1999 and $1.07 in 2000. However, the Partnership's future
performance will depend on actual oil and gas prices, production levels and
operating costs, which could materially affect Middle Bay's continuation
analysis in either direction. This liquidation valuation estimated by Middle Bay
could, however, prove to be incorrect since the estimate is based on various
pricing and other market-related assumptions.

                  Lack of Independent Representative; Fairness Opinion. Middle
Bay did not engage an independent representative to negotiate the terms of the
Exchange Offer on behalf of the Unitholders. As a result, the Exchange Value and
other terms of the Exchange Offer may not be as favorable as the terms that an
independent representative might have obtained. However, Middle Bay did retain
an independent third party to render an opinion with regard to the fairness of
the Exchange Offer to the Investors in the Partnership. See "The Exchange Offer
- - Fairness Opinion."

                  Valuation Conflict of Interest; Benefits of Exchange Offer to
Middle Bay. The determination of the Exchange Value by Middle Bay involves a
conflict of interest because of Middle Bay's control of Enex's duties as General
Partner of the Partnership and in connection with Middle Bay's purchase of the
Partnership's assets. Accordingly, Middle Bay's determination may not reflect
the value of the Partnership's net assets if all such assets were sold to an
unaffiliated third party or parties in an arm's-length transaction. During 1998,
certain properties of the Partnership have been sold to unaffiliated third
parties at prices both less than and greater than the valuations used in
computing the Exchange Value; however, no attempt has been made to sell all of
the Partnership's properties to any third party. The proceeds from the sale of


                                     - 21 -
<PAGE>   34
Partnership properties in 1998 have been distributed to the Partnership's
Unitholders and General Partner in accordance with their respective interests.
As controlling shareholder of the General Partner of the Partnership, Middle Bay
owes fiduciary duties to the Investors and also owes a duty to the stockholders
of Middle Bay and the minority stockholders of Enex. Middle Bay expects to
benefit from the Exchange by increasing its Proved Reserves, cash flow and
borrowing base for purposes of financing future acquisitions. While Middle Bay
believes that it has fulfilled its fiduciary obligations in its determination of
the Exchange Value, because of the potential benefits to Middle Bay from the
acquisition of the Partnership's properties pursuant to the Exchange Offer, no
degree of objectivity or professional competence can eliminate the inherent
conflict of interest.

                  Uncertainties in the Method of Determining Exchange Value.
While Middle Bay believes that the method of determining the Exchange Value
represents a fair, reasonable and proper method of valuing the Partnership Units
based on the Gruy Report, the method of determining the Exchange Value is
subject to various uncertainties and may have resulted in a valuation that would
differ from offers made by independent bidders. The components of the Exchange
Value and the factors underlying these uncertainties are described herein.

                  Other Assets and Liabilities. The method of determining the
Exchange Value takes into account the estimated value of other assets and
liabilities of the Partnership as of September 30, 1998. In calculating the
Exchange Value, the net book value of current assets and liabilities of the
Partnership was derived from the Partnership's unaudited balance sheet as of
September 30, 1998 prepared on an accrual basis. The balance sheet book value of
current assets and liabilities used by Middle Bay in the calculation of fair
market value which was included in the Exchange Value may be higher or lower
than the actual fair market value of those assets and liabilities.

                  Subsequent Events. The Exchange Value will not be adjusted to
reflect changes in the present value of the estimated future net cash flows
attributable to the Proved Reserves of the Partnership after October 1, 1998,
although oil and gas prices in subsequent periods may differ from the prices
used on the date of the reserve reports.

                  No Fractional Shares. No fractional shares will be issued in
connection with the Exchange Offer. An Investor who would otherwise be entitled
to a fractional share of Series C Preferred will be paid cash in lieu of such
fractional shares.

                  Inherent Uncertainties in Estimating Reserves and Future Net
Cash Flows. The present value of estimated future net cash flows from Proved
Reserves of the Partnership, a significant factor considered in determining the
Exchange Value, cannot be determined with a high degree of certainty. There are
numerous uncertainties inherent in estimating quantities of Proved Reserves and
on projecting future rates of production, future development, recompletion and
workover expenditures, prices to be received upon the sale of oil and gas and
costs to be incurred in production. The data set forth in the Gruy Report,
included in Exhibit "A" to this Prospectus, represent estimates only and may
vary materially from the quantities of oil and gas actually recovered and the
future net cash flows received upon the sale thereof. Middle Bay's


                                     - 22 -
<PAGE>   35
use of the Gruy Report in determining the Exchange Value could, therefore,
result in an undervaluation of the Partnership Units.

                  Changes in Form and Nature of Investment Vehicle and Related
Tax Status. The Partnership and its Predecessor Partnerships since inception
have been operated as partnerships under the Internal Revenue Code. Upon
consummation of the Exchange, the assets of the Partnership will be owned and
operated by Middle Bay, a "C" corporation which is subject to federal and state
income taxes. Unlike distributions from the Partnership, dividends of the Series
C Preferred shares are subject to tax at the Middle Bay corporate level and at
the individual shareholder level. Unitholders rights with regard to
distributions and matters governing control and management of the business and
assets of the Partnership will no longer be determined by the Partnership
Agreement and New Jersey partnership law but will be controlled by the Articles
of Incorporation and Bylaws of Middle Bay and the Alabama Business Corporation
Act. The Series C Preferred is generally nonvoting except on matters which would
adversely affect any holder's rights or preferences. Unitholders presently have
the right to vote on and may by vote of a majority in interest approve or
disapprove or take certain actions, including amendments to the Partnership
Agreement, the sale of all or substantially all of the assets of the Partnership
and removal of the General Partner. See "Corporate Governance of Middle Bay" and
"Comparative Rights of Security Holders."

                  Changes in Business Risks. Upon consummation of the Exchange
Offer, former Unitholders (except those who choose to elect their dissenters' or
appraisal rights) will be shareholders of Middle Bay which, as a corporation,
has historically retained and for the foreseeable future intends to retain any
earnings and cash flow to support the growth of its business and to leverage its
acquisition of new exploratory, developmental and producing properties through
the use of debt financing. The Partnership's business and investment objectives
have been primarily to invest in and receive income from interests in producing
oil and gas properties without incurring debt or subjecting itself to the risks
of exploratory drilling. Accordingly, Unitholders who become shareholders of
Middle Bay will be subject to different and greater risks from those associated
with an investment in the Partnership. See "Risks Related to Middle Bay," below.

RISKS RELATED TO MIDDLE BAY

                  Potential Decline in Market Price of Middle Bay Securities.
The Exchange Value of $10.43 per Unit together with the cash distributions of
approximately $5.85 per Unit paid by the Partnership since its consolidation in
July, 1997 to date total $16.28 per Unit compared to an Investor's average
initial investment of $10.00 per Unit at the time of consolidation in July,
1997. There is presently no trading market in the Series C Preferred, and there
can be no assurance that a trading market will develop following the Exchange.
Investors would be exposed to a loss on their investment if the market price for
the Series C Preferred or the underlying common stock declines below the Unit
Exchange Price. Further, the Conversion Ratio of one share of common stock for
each Preferred Share represents an assumed value upon conversion of the
underlying common stock of at least $5.00 per share. The market price for the
common stock fluctuated during 1997 from a high of $12 per share to a low of
$5-1/2 per share, with an average daily trading volume of 2,762 shares, and has
fluctuated from a high of $10 per share to a low of $2.43 per share during 1998.

<PAGE>   36
prices in the oil and gas industry in general and the effect of those lower
prices on Middle Bay in particular could also adversely affect the market price
of the common stock. A downturn in the general economic and stock market
conditions or in the drilling record and production performance of Middle Bay or
results of operations for Middle Bay that are lower than expected by the
marketplace could be expected to have a similar impact on the common stock. The
estimated number of shares of Series C Preferred offered in exchange for
Partnership Units has been determined by dividing the Exchange Value of the
assets of the Partnership by the Series C Preferred liquidation value of $5.00
per share. The Exchange Value was determined by Middle Bay in reliance upon the
Gruy Report and the determination of fairness by an independent investment
banking firm. See "The Exchange Value - Fairness Opinion."

                  Losses From Operations.  The historical financial data for
Middle Bay reflect a net loss of $16,184,032 for the year ended December 31,
1997 and net income of $205,500 for the year ended December 31, 1996, a net loss
of $2,535,014 for the nine months ended September 30, 1998 and a net loss of
$338,310 for the nine months ended September 30, 1997. Middle Bay had total
revenues of $11,432,995 and $4,886,421 for the years ended December 31, 1997 and
1996, respectively, and $5,694,760 and $4,148,588 for the nine months ended
September 30, 1998 and 1997, respectively. The substantial loss for the year
ended December 31, 1997 was due primarily to a noncash charge against the
carrying value of certain of Middle Bay's oil and gas properties for impairment
of values due to lower future cash flows expected from such properties
attributable to lower oil and gas prices and other factors. Middle Bay's ability
to maintain its financing arrangements, produce its oil and gas reserves and
service its debt obligations could be adversely affected by a continuing lack of
profitability. Any improvement in profitability of Middle Bay will be dependent
upon, among other factors, improvement in the development of reserves and
production therefrom, results of exploratory drilling and oil and gas pricing,
and there can be no assurance that such improvement will occur.

                  Inherent Uncertainties in Estimating Reserves and Future
Revenues. This Prospectus contains estimates of Middle Bay's oil and gas
reserves and the future net revenues therefrom which have been prepared by
various independent petroleum engineers. Estimates of commercially recoverable
oil and gas reserves and of future net cash flows derived therefrom are based
upon a number of variable factors and assumptions, such as historical production
from the subject properties, comparison with other producing properties, the
assumed effects of regulation by government agencies and assumptions concerning
future operating costs, severance and excise taxes, abandonment costs,
development costs and workover and remedial costs, all of which may vary
considerably from actual results. All such estimates are to some degree
speculative, and various classifications of reserves are only attempts to define
the degree of speculation involved. For these reasons, estimates prepared by
different engineers or by the same engineers at different times of the
commercially recoverable reserves of oil and natural gas attributable to any
particular property or group of properties, the classification, cost and risk of
recovering such reserves and estimates of the future net cash flows expected
therefrom may vary substantially. Therefore, Middle Bay's actual production,
revenues, severance taxes, development expenditures, workover and remedial
expenditures, abandonment expenditures and operating costs with respect to its
reserves will likely vary from such estimates, and such variances may be
material.


                                     - 24 -
<PAGE>   37
                  In addition, actual future net cash flows will be affected by
factors such as actual production, supply and demand for oil and natural gas,
availability and capacity of gas gathering systems and pipelines, curtailments
in consumption by natural gas purchasers, changes in governmental regulations or
taxation and the impact of inflation on costs. The timing of actual future net
revenues from proved reserves, and thus their actual present value, can be
affected by the timing of the incurrence of expenditures in connection with
development of oil and gas properties. The 10% discount factor, which is
required by the SEC to be used to calculate present value for reporting
purposes, is not necessarily the most appropriate discount factor based on
interest rates in effect from time to time and risks associated with the oil and
gas industry. Discounted present value, no matter what discount rate is used, is
materially affected by assumptions as to the amount and timing of future
production, which may and often do prove to be inaccurate.

                  Development of Additional Reserves. Middle Bay's future
success may also depend upon its ability to find or acquire additional oil and
gas reserves that are economically recoverable. Except to the extent that Middle
Bay conducts successful exploration or development activities or acquires
properties containing Proved Reserves, the Proved Reserves of Middle Bay will
generally decline as reserves are produced. There can be no assurance that
Middle Bay will be able to discover additional commercial quantities of oil and
gas or that Middle Bay will be able to continue to acquire interests in
underdeveloped oil and gas fields and enhance production and reserves by
conducting workovers and recompletions, drilling replacement wells and drilling
development wells or that Middle Bay will have success drilling productive wells
and acquiring underdeveloped properties at economical prices.

                  Retention and Attraction of Key Personnel. Middle Bay depends
to a large extent on the abilities and continued participation of certain key
employees, the loss of whose services could have a material adverse effect on
Middle Bay's business. In an effort to minimize the risk, Middle Bay has entered
into employment agreements with certain key employees, including John J.
Bassett, President and Chief Executive Officer. Furthermore, as a result of
Middle Bay's recent growth, Middle Bay is currently seeking additional
accounting and operating personnel. There can be no assurance that Middle Bay
will be able to attract and retain such personnel on acceptable terms, and the
failure to do so could have a material adverse effect on Middle Bay.

                  Potential Effective Control of Middle Bay by Single
Shareholder. Kaiser-Francis Oil Company ("Kaiser-Francis"), an independent,
privately-owned company, owns approximately 39% of Middle Bay's presently
outstanding common stock and, should it desire to do so, could effectively
control Middle Bay through the election of its nominees as directors of the
Company or by exercising influence upon management decisions and policy.
Kaiser-Francis is a privately-held company whose majority shareholder is George
B. Kaiser. See "Corporate Governance of Middle Bay - Security Ownership of
Certain Beneficial Owners."

                  Potential Dilutive Effect of Authorized but Unissued Capital
Stock. As of September 30, 1998, there are 11,447,636 unissued shares of common
stock and 9,733,333 shares of preferred stock authorized under Middle Bay's
Articles of Incorporation for future issuance without shareholder approval.
1,500,000 of these additional shares of common stock have been reserved for
possible exercise of stock options described under "Compensation Under Plans,"
and 2,300,000 shares have been reserved for the


                                     - 25 -
<PAGE>   38
possible conversion of the Series C Preferred shares issuable pursuant to the
Exchange. The remaining additional shares of common or preferred stock may be
issued by Middle Bay's Board of Directors without shareholder approval for a
variety of corporate purposes, including possible future public or private
offerings to raise additional capital, to facilitate corporate acquisitions or
for executive incentive compensation.

                  Assuming all Unitholders accept the Exchange Offer and convert
their Series C Preferred into shares of common stock, Investors would own
1,006,480 shares of Middle Bay common stock (excluding shares issuable to Enex
pursuant to the Exchange), or 10.6% of the then outstanding shares of common
stock. Investors' potential percentage ownership of Middle Bay shares of common
stock is subject to dilution when and as additional shares of currently
authorized but unissued common stock may be issued by Middle Bay for
acquisitions or other corporate purposes, including but not limited to the
exercise of options or warrants or the conversion of the outstanding Series B
Preferred stock. See "Description of Middle Bay Equity Securities Certain
Effects of Authorized But Unissued Shares."

                  Possible Delisting and Risk of Low-Priced Securities. Middle
Bay common stock is currently being quoted on the NASDAQ Small Cap Market under
the symbol "MBOC." Series C Preferred shares are expected to be approved for
listing, subject to official notice of issuance, on the NASDAQ Small Cap Market.
If Middle Bay is unable to satisfy the NASDAQ Small Cap Market maintenance
criteria in the future, its common stock and the Series C Preferred shares could
be delisted from trading on the NASDAQ Small Cap Market. If it did not qualify
for such listing, trading, if any, would thereafter be conducted in the
over-the-counter market in the so-called "pink sheets" or the "Electronic
Bulletin Board" of the National Association of Securities Dealers, Inc.
("NASD"), and consequently Investors could find it more difficult to dispose of
or to obtain accurate quotations as to the price of the Company's securities.

                  The Securities Enforcement and Penny Stock Reform Act of 1990
requires additional disclosure relating to the market and in connection with
trades in any stock defined as "penny stock." SEC regulations generally define a
penny stock to be an equity security that has a market price of less than $5.00
per share, subject to certain exceptions. Such exceptions include any equity
security listed on NASDAQ and any equity security issued by an issuer that has
net tangible assets of at least $2,000,000, if such issuer has been in
continuous operation for three years. Unless an exception is available, the
regulations require the delivery, prior to any transaction involving a penny
stock, of a disclosure schedule explaining the penny stock market and the risks
associated therewith. The regulations also require that broker/dealers who
recommend such securities to persons other than established customers and
accredited investors must make a special written suitability determination for
the purchaser and receive the purchaser's written agreement to a transaction
prior to sale.

                  If Middle Bay's securities become subject to the regulations
applicable to penny stocks, the market liquidity for the Company's securities
could be severely affected. In such event, the regulations on penny stocks could
limit the ability of broker/dealers to sell Middle Bay's securities and thus the
ability of Investors to sell their Middle Bay securities in the secondary
market. Middle Bay's common stock was trading below $5.00 per share for a
portion of the quarter ended September 30, 1998, and the last reported sales
price on the NASDAQ Small Cap Market for the common stock as of November 25,
1998 was $3-1/8 per share; however, Middle Bay does not expect its
publicly-traded securities to be subject to the penny stock


                                     - 26 -
<PAGE>   39
rules because the common stock is listed on the NASDAQ Small Cap Market (and the
Series C Preferred is expected to be so listed), and Middle Bay's net tangible
assets at September 30, 1998 were approximately $22,700,000.

RISKS RELATED TO THE OIL AND GAS INDUSTRY

                  Risk of Oil and Gas Operations. Middle Bay's operations are
subject to all of the risks normally incident to the operation and development
of oil and gas properties and the drilling of oil and gas wells, including
encountering unexpected formations or pressures, blowouts, cratering and fires
and, in horizontal wellbores, the increased risk of mechanical failure and
collapsed holes, the occurrence of any of which could result in personal
injuries, loss of life, environmental damages and other damage to the properties
of Middle Bay or others. In addition, because Middle Bay acquires interests in
underdeveloped oil and gas fields that have been operated by others for many
years, Middle Bay may be liable for any damage or pollution caused by any prior
operations of such oil and gas fields. In accordance with customary industry
practice, Middle Bay is not fully insured against these risks, nor are all such
risks insurable. Accordingly, there can be no assurance that such insurance as
Middle Bay does maintain will be adequate to cover all losses or exposure for
liability.

                  Current Oil and Gas Industry Conditions. 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 supply of and demand for
oil and natural gas, market uncertainty and a variety of geopolitical and other
factors that are beyond the control of Middle Bay. These factors include
political conditions in the Middle East and other countries, the foreign supply
of oil and natural gas, the price of foreign imports, the level of consumer
product demand, weather conditions, domestic and foreign governmental
regulations, the price and availability of alternative fuels and overall
economic conditions. Lower oil and natural gas prices also may reduce the amount
of Middle Bay's oil and natural gas that is economic to produce. In addition,
the marketability of Middle Bay's production depends upon the availability and
capacity of gas gathering systems and pipelines.

                  Government Regulation; Environmental Risks. Middle Bay's
business is regulated by certain federal, state, and local laws and regulations
relating to the development, production, marketing and transmission of oil and
gas, as well as environmental and safety matters. There can be no assurance that
laws and regulations enacted in the future will not adversely affect Middle
Bay's exploration for, or the production and marketing of, oil and gas.

                  Oil and gas operations are subject to extensive federal, state
and local laws regulating the discharge of materials into the environment or
otherwise relating to the protection of the environment. 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
penalties for failure to comply. The regulatory burden on the oil and gas
industry increases its cost of doing business and consequently affects its
profitability. These laws, rules and regulations affect the operations of Middle
Bay. Compliance with environmental requirements generally could have a material
adverse effect upon the capital expenditures, earnings or competitive position
of Middle Bay.


                                     - 27 -
<PAGE>   40
                  Competition. The oil and gas exploration and production
business is highly competitive. A large number of companies and individuals
engage in the drilling for and production of oil and gas, and there is a high
degree of competition for desirable oil and gas properties suitable for drilling
and for materials and third-party services essential for their exploration and
development. Many of Middle Bay's competitors have greater financial and other
resources than does Middle Bay.


                     PRICE RANGE OF MIDDLE BAY COMMON STOCK,
                           DIVIDENDS AND DISTRIBUTIONS

         Middle Bay's common stock has been on the National Association of
Securities Dealers, Inc. Automated Quotation System ("NASDAQ Small Cap Market")
under the symbol "MBOC" since September 29, 1995. As of September 30, 1998,
there were 8,530,592 shares of Middle Bay common stock issued and outstanding.
There is no public market for the Partnership Units; however, Middle Bay has
applied for inclusion of the Series C Preferred on the NASDAQ Small Cap Market.

</TABLE>

         Middle Bay's policy is to retain any earnings and cash flow to support
the growth of Middle Bay's business. Accordingly, the Board of Directors of
Middle Bay has never declared cash dividends on its


                                     - 28 -
<PAGE>   41
common stock and does not plan to do so in the foreseeable future. Furthermore,
the terms of Middle Bay's debt agreements prohibit the payment of cash dividends
on Middle Bay's common stock.

         The Partnership makes cash distributions to Investors from Partnership
cash flow. The following table sets forth the amount of cash distributions paid
per Unit by the Partnership to its Investors during the periods indicated:

<TABLE>
<CAPTION>
             1997                1998

            $ 3.07              $ 2.78
</TABLE>

         The last distribution made by the Partnership was in October, 1998.

         On November 25, 1998, the last reported sales price of Middle Bay's
common stock on the NASDAQ Small Cap Market was $3-1/8 per share. The Series C
Preferred shares are expected to be approved for listing, subject to official
notice of issuance, on the NASDAQ Small Cap Market. However, there is no present
trading market in the Series C Preferred, and there can be no assurance that a
trading market will develop following consummation of the Exchange Offer.

         Because the market price for Middle Bay's common stock is subject to
fluctuation, the market value of the common stock underlying the Series C
Preferred that an Investor will receive in connection with the Exchange Offer
may increase or decrease prior to the Exchange. Holders of Partnership Units are
urged to obtain current market quotations for the Middle Bay common stock.


                         THE EXCHANGE OFFER AND PROPOSAL

DESCRIPTION OF THE EXCHANGE OFFER

         Middle Bay is offering to exchange Series C Preferred for Partnership
Units in the Partnership (the "Exchange"). Investors who tender their
Partnership Units will receive the number of shares of Series C Preferred set
forth below. In connection with the Exchange Offer, Middle Bay is submitting a
Proposal to Investors in the Partnership to amend the Partnership Agreement to
provide for the transfer of all of the assets and liabilities of the Partnership
to Middle Bay as of the October 1, 1998 Effective Date in exchange for Series C
Preferred and the pro-rata distribution of such consideration in liquidation of
the Partnership.

         If the Exchange Offer is consummated, each holder of a Unit who tenders
his Units in connection with the Exchange Offer will receive 2.086 shares of
Series C Preferred whose liquidation value, in the aggregate, is equal to $5.00
per share ($10.43 per Unit). Fractional shares of Series C Preferred will not be
issued in connection with the Exchange Offer or liquidation of the Partnership.
A partner in the Partnership otherwise entitled to a fractional share of Series
C Preferred will be paid in cash in lieu of such fractional share.


                                     - 29 -
<PAGE>   42
THE PROPOSAL

         Middle Bay is submitting to Investors in the Partnership the Proposal
to adopt an amendment to the Partnership Agreement annexed as Exhibit "B" to
this Prospectus. The amendment, if adopted by the Partnership in accordance with
amendment procedures in the Partnership Agreement, as amended, will provide for
the following steps:

         1)       The transfer to Middle Bay, in exchange for the Series C
                  Preferred set forth below, of all of the assets of the
                  Partnership and the assumption by Middle Bay of all
                  liabilities of the Partnership, effective as of the Effective
                  Date.

         2)       The dissolution of the Partnership and the distribution to
                  Investors (other than those Investors who elect to exercise
                  limited appraisal or dissenters' rights) of the Series C
                  Preferred allocable to their interests in liquidation promptly
                  following the Closing Date.

         3)       Nonconsenting Investors who elect to exercise the limited
                  appraisal or dissenters' rights described under "Limited
                  Appraisal and Dissenters' Rights," below, will receive cash
                  rather than Series C Preferred shares.

         Each Investor who tenders his Partnership Units pursuant to the
Exchange Offer will, by that tender, consent to the proposal for the
Partnership. If the Partnership adopts the Proposal by the consent of a
prescribed majority (60% or greater) of the Partnership Units in the
Partnership, all Investors in the Partnership, whether or not they tendered
their Units in the Exchange Offer, will receive the same amount of Series C
Preferred as they would have received had they tendered their Partnership Units.
Consummation of the Exchange Offer is conditioned upon approval by the
Partnership of the Proposal. Because Middle Bay controls (through the General
Partner) Partnership Units in excess of 50% of the total outstanding Units and
because Middle Bay has indicated it will cause those Units to approve the
Exchange Offer, approval of the Proposal is more than likely assured. Investors
who do not return a completed Letter of Transmittal will not receive Middle Bay
Series C Preferred until Middle Bay has distributed and Investors have returned
an executed Transfer Application issuable to them in the Exchange, which may
result in a delay in receiving the Series C Preferred if the Transfer
Application is not properly returned.

TIMING OF SERIES C PREFERRED ISSUANCE

         Assuming that the Proposal is adopted and the Exchange Offer is
consummated, Middle Bay will have the benefit of the Partnership's assets and
associated cash flows commencing on the Effective Date. The Series C Preferred
issued in the Exchange will be freely transferable immediately following
issuance; however, there presently is no trading market in the Series C
Preferred, and there is no assurance that a trading market will develop
following the Exchange.

         On the Closing Date, Middle Bay will cause certificates representing
the Series C Preferred issuable in the Exchange to be registered in the name of
the holders who have accepted the Exchange Offer. Middle Bay will also cause a
certificate representing the shares of Series C Preferred that will be issued to
participants upon liquidation of the Partnership to be issued in the name of the
Partnership, pending


                                     - 30 -
<PAGE>   43
dissolution, liquidation and winding-up of the Partnership. Immediately
thereafter, Middle Bay will cause the shares of Series C Preferred issued in the
name of the Partnership to be transferred into certificates representing Series
C Preferred registered in the names of the individual participants remaining in
the Partnership following liquidation.

CONDITIONS TO THE EXCHANGE OFFER

         Middle Bay, at any time on or prior to the Closing Date, may refuse to
consummate, abandon or terminate the Exchange Offer and withdraw the Proposal
after the date of this Prospectus only if (1) a material change shall have
occurred or been threatened (or any development shall have occurred or been
threatened involving a prospective material change) affecting (or likely to
affect) the business or properties of Middle Bay or the Partnership, or (2)
Investors representing more than 175,000 Units elect to pursue appraisal or
dissenters' rights, or (3) if Middle Bay shall have become aware of any facts or
circumstances that have or may have material adverse significance with respect
to Middle Bay's operations. If any event shall occur or any matter shall have
been brought to the attention of Middle Bay that, materially affects the
Partnership, or the Exchange Offer for Interests in the Partnership, Middle Bay
may refuse to accept tenders of Interest in the Partnership or may modify or
amend the Exchange Offer to take the event or matter into account. For purposes
of conditions (1) and (3) above, the term "material" shall be construed to mean
a condition existing or threatened which, in the judgment of Middle Bay, has
caused or is likely to cause a 5% or greater decrease in the Exchange Value of
the Units or a 5% or greater decrease in Middle Bay's anticipated net revenues
or cash flow from the Partnership's properties for 1999.

         The absence of a material change affecting Middle Bay or the
Partnership and the limitation on the number of dissenters are the only material
conditions to the Exchange Offer. If those conditions have not been fulfilled or
the Exchange Offer is withdrawn by Middle Bay, each Letter of Transmittal
tendering an Interest or consenting to the Proposal will be void, and no Series
C Preferred will be issued in Exchange for the Interests in the Partnership.

REGULATORY APPROVALS

         Upon effectiveness of the registration statement of which this
prospectus constitutes a part, federal or state regulatory approval is required
in connection with the Exchange Offer or the adoption of the Proposal by the
Partnership.

LIMITED APPRAISAL AND DISSENTERS' RIGHTS

         Unitholders who do not vote in favor of or who oppose the Proposal will
have certain appraisal and dissenters' rights. Such Investors will have the
option to receive cash in lieu of the Series C Preferred based on the
liquidation value determined by Middle Bay based on the Gruy Report and assuming
an orderly liquidation of the Partnership's assets over a one-year period. Such
rights are not required by New Jersey partnership law, and the appraisal rights
afforded Investors are those provided by the Partnership Agreement. The
liquidation value per Unit for purposes of those Unitholders electing to receive
cash for their Units has


                                     - 31 -
<PAGE>   44
been determined to be $8.96. Such Unitholders shall be entitled to receive cash
payment for their tendered Units within 30 days of the completion of the
Exchange Offer. See the Gruy Report included herewith for a detailed explanation
of the determination of liquidation value. See, also, "Partnership Liquidation
Analysis" on page 49.

         Unitholders residing in California will be afforded the option to elect
limited dissenters' rights in accordance with the requirements for roll-up
transactions under the California Code. By voting against the Proposal,
Investors in the State of California who choose to exercise their California
dissenters' rights will receive the cash equivalent of the Exchange Value of
their interests. If that cash amount is greater than the liquidation value of
the Units, dissenting California Investors will receive more cash than they
would otherwise receive by electing appraisal rights under the Partnership
Agreement. California Investors hold less than 1% of the Interests in the
Partnership, and the impact of the exercise of appraisal rights or dissenters'
rights under California law is not likely to materially affect the number of
shares of Series C Preferred issued or cash paid pursuant to appraisal or
dissenters' rights by Middle Bay in connection with the Exchange Offer.

DISTRIBUTION OF SERIES C PREFERRED

         Each Investor who returns a completed Letter of Transmittal, even if he
withholds consent to the Proposal, will thereby have provided to Middle Bay the
necessary information to issue the Series C Preferred provided the Exchange
Offer is consummated. Assuming that the Proposal is adopted by the Partnership
and the Exchange Offer is consummated, Investors who have not otherwise chosen
to exercise their dissenters' or appraisal rights and who have returned a
completed Letter of Transmittal will receive the Series C Preferred issuable to
them in the Exchange promptly after the Closing Date.

         An Investor who does not return a completed Letter of Transmittal will
not be eligible to receive the Series C Preferred after the Closing Date, if the
Exchange and Proposal are approved. Instead, the Series C Preferred attributable
to that Investor's Partnership Units will be held of record by the Partnership.
Immediately after the Closing Date, Middle Bay will deliver a Transfer Notice to
each Investor who has not returned a Letter of Transmittal. The Transfer Notice
should be completed and returned to Middle Bay promptly. Upon return of the
executed Transfer Notice, Middle Bay will have the Series C Preferred
transferred and delivered to the Investor.

INTERESTS OF CERTAIN PERSONS IN THE EXCHANGE AND PROPOSAL

         In considering the recommendation of the General Partner, Investors
should be aware that the General Partner has interests in the Exchange that are
in addition to the interests of the Partnership and the Investors generally.
Middle Bay controls and has a common Board of Directors with the General Partner
of the Partnership, and its determination of the Exchange Value involves an
inherent conflict of interest. Both the General Partner and Middle Bay owe
fiduciary duties to the Investors in the Partnership. In addition, Middle Bay
and Enex owe a duty to their respective stockholders. While Middle Bay believes
that it has fulfilled these fiduciary obligations for itself and Enex in its
determination of the Exchange Value,


                                     - 32 -
<PAGE>   45
which is supported, in part, by the Gruy Report and the Fairness Opinion, no
degree of objectivity or professional competence can eliminate the inherent
conflict of interest.

RESALE OF MIDDLE BAY SERIES C PREFERRED

         Issuance of the Middle Bay Series C Preferred to be received by
Investors who tender their Partnership Units and the shares to be received by
Unitholders in liquidation of the Partnership will be registered under the
Securities Act. Middle Bay has applied for listing of the Series C Preferred
shares on the NASDAQ Small Cap Market, subject to notice of issuance, and such
application is expected to be approved. Subject to the availability of a trading
market (of which there can be no assurance), the Series C Preferred shares may
be traded freely and without restriction by those Investors of the Partnership
not deemed to be an "affiliate" of the Partnership, as that term is defined in
the rules under the Securities Act. "Affiliates" are generally defined as
persons who control, are controlled by or are under common control with the
Partnership at the time of the Exchange. Accordingly, "affiliates" generally
will include the General Partner and any Investor who owns in excess of 10% of
the Partnership Interests. Middle Bay Series C Preferred received by those
Investors who are deemed to be "affiliates" of the Partnership may be resold
without registration as provided by and subject to the limitations of Rules 144
and 145 of the SEC, or as otherwise permitted under the Securities Act. This
Prospectus does not cover any resales of Middle Bay Series C Preferred received
by affiliates of the Partnership or by certain family members or related
interests. Any Unitholder who becomes an affiliate of Middle Bay will be subject
to similar restrictions under Rule 144.

FRACTIONAL SHARES

         No fractional shares of Middle Bay Series C Preferred will be issued.
Fractional share interests which would otherwise be issuable shall entitle the
holder thereof to receive, in lieu of such fractional interest, an amount of
cash equal to the product of such fraction multiplied by the $5.00 per share of
Middle Bay Series C Preferred used in the Exchange Value. Payment in amounts of
$1.00 or more for fractional shares will be made concurrently with the issuance
of the Series C Preferred shares.

RESALES OF SERIES C PREFERRED; STOCK MARKET LISTING

         All of the currently issued and outstanding shares of common stock of
Middle Bay are admitted for trading and quoted on the NASDAQ Small Cap Market,
and application has been made to the National Association of Securities Dealers,
Inc. for admission for trading on the NASDAQ Small Cap Market of the shares of
Series C Preferred to be issued in connection with the Exchange Offer. There can
be no assurance, however, that a trading market will develop in the Series C
Preferred shares or that, in the event a trading market develops, at what price
the Series C Preferred may be sold.

ACCOUNTING TREATMENT

         The Exchange will be accounted for as a purchase by Middle Bay.
Accordingly, the purchase price will be allocated to assets and liabilities
based on their estimated fair values as of the date of acquisition.

CLOSING DATE

         The Exchange Offer is expected to be consummated on the Closing Date,
which will be no more than five days following the Expiration Date. Middle Bay
may withdraw the Exchange Offer at any time prior to the Expiration Date under
certain circumstances, including the existence of any state or federal statute,
rule, regulation or order or entry of any judicial or administrative order that
would prohibit the transaction contemplated by the Exchange Offer and the
Proposal. The Exchange Offer to the Partnership is conditioned upon consent of a
majority of the Units to the Proposal and the absence of any material adverse
development affecting the Partnership, as determined by Middle Bay in its sole
discretion (see "The Exchange Offer and Proposal - Conditions to the Exchange"
herein). On the Closing Date, subject to satisfaction of these conditions and
the condition that holders of not more than 175,000 Units elect to exercise
dissenters' rights, Middle Bay intends to accept all Units validly tendered and
not withdrawn pursuant to the Exchange Offer.

OPERATIONS AFTER THE EXCHANGE

         Middle Bay is an independent oil and gas company engaged in the
acquisition of producing properties and the exploration, development and
production of oil and gas in the contiguous United States, primarily in
the Mid-Continent and Gulf Coast regions. Upon consummation of the Exchange ,
Middle Bay will operate the acquired Partnership assets as it operates its oil
and gas properties or may sell such assets to third parties at any time.

EXPENSES; FEES

         All expenses incurred in connection with the Exchange Offer and the
Proposal and the transaction contemplated thereby will be paid by Middle Bay.
Middle Bay will pay the expenses incurred in connection with the Exchange Offer
and will pay all fees and expenses in connection with this Prospectus, including
fees and expenses payable in connection with the Registration Statement of which
this Prospectus is a part.

MIDDLE BAY'S DIVIDEND POLICY

         Series C Preferred. The holders of Series C Preferred are entitled to
cumulative cash dividends of $.50 per annum, payable semi-annually on March 31st
and September 30th of each year (measured by Middle Bay's fiscal year). No
dividends may be authorized or paid or set apart for payment or other
distribution of cash or other property authorized or made directly or indirectly
by Middle Bay with respect to any shares of Middle Bay common stock or other
junior securities of Middle Bay unless the full cumulative dividends on all
outstanding shares of Series C Preferred shall have been paid or such dividends
have been authorized and set apart for payment with respect to the Series C
Preferred shares.

         Common Stock. Middle Bay's policy is to retain its earnings and cash
flow to support the growth of Middle Bay's business. Accordingly, the Board of
Directors of Middle Bay has never declared cash dividends on its common stock
and does not plan to do so in the foreseeable future. Furthermore, the terms of
its credit agreement with its principal lender prohibit the payment of cash
dividends on Middle Bay's common stock.

                      METHOD OF DETERMINING EXCHANGE VALUE

GENERAL

         H.J. Gruy and Associates, Inc. ("Gruy") is the independent petroleum
engineering firm most familiar with the properties in which the Partnership has
interests and has prepared the annual reserve report on the Partnership's
reserves since inception of the Partnership and its Predecessor Partnerships.
Gruy is actively involved in the evaluation of producing oil and gas properties
and is widely recognized in its field. Gruy is an independent consulting firm as
provided in the Standards Pertaining to the Estimating and Auditing of Oil and
Gas Reserves Information promulgated by the Society of Petroleum Engineers.

         The Exchange Value has been assigned to the Partnership Units to
determine the number of shares of Series C Preferred to be offered for
Partnership Units. The Exchange Value was determined by Middle Bay in reliance
upon the Gruy Report and is not the result of negotiations with independent
representatives of the Partnership. Accordingly, the Exchange Value may not
reflect the value of the Partnership Units or the value of the Partnership
properties if all the assets were to be sold to an unaffiliated third party or
parties in an arm's-length transaction. Middle Bay did not seek third-party bids
for the sale of the Partnership's assets. Management of Middle Bay has
substantial experience in evaluating and operating oil and gas properties in the
Partnership's production areas and believes on the basis of that experience that
the methodology employed by Gruy in determining the fair market value of the
Proved Reserves of the Partnership is fair to Investors and is considered in the
oil and gas industry as being favorable to sellers of producing properties.

         Middle Bay did not instruct Gruy as to pricing, cost or other economic
parameters or methods or the assessment of reserve characteristics, nor did it
limit the scope of Gruy's investigation for purposes of preparing the fair
market value appraisal. Middle Bay provided Gruy with basic evaluation data for
its use in determining the Partnership's reserves and their value. Gruy prepared
its own reserve estimate of the Partnership's properties. Middle Bay did not
direct Gruy as to the amount of consideration to be paid to the Partnership for
its property interests nor provide any information to Gruy on amounts to be paid
to Unitholders. The amount of consideration to be paid was determined by Middle
Bay's Board of Directors based upon Gruy's estimates of the fair market value of
those interests. Gruy did not opine on the fairness of the transaction to
Unitholders; however, Middle Bay did acquire an independent report and opinion
regarding the fairness to Unitholders of the consideration for which the
Partnership's assets will be sold to Middle Bay if the Proposal is approved by
Unitholders.

         The number of shares of Series C Preferred to be issued pursuant to the
Exchange Offer has been determined relative to a Total Exchange Value assigned
to the Partnership Units of $10.43 per Unit. The number of shares of Series C
Preferred offered in exchange for Partnership Units will be determined by
dividing the Total Exchange Value of the assets of the Partnership by $5.00,
which is the liquidation value per share of the Series C Preferred.


                                     - 35 -
<PAGE>   48
         The Total Exchange Value reflects the fair market value of Proved
Reserves of the Partnership's oil and gas assets (as determined by Gruy) and all
other assets and liabilities of the Partnership (including probable and possible
reserves). These components reflect (i) the estimated fair market value of
future net cash flows from Proved Reserves, plus probable and possible reserves,
of the Partnership as of September 30, 1998, discounted 10% per year and
calculated with escalated prices and costs, (ii) the net book value of current
assets and liabilities of the Partnership as of September 30, 1998 and (iii) the
general intangibles of the Partnership. Based on management's experience in
evaluating reserve acquisition opportunities and transactions in the
Partnership's production areas, Middle Bay believes that the components of the
Exchange Value reflect all appropriate valuation criteria for the Partnership in
accordance with industry practice. Each component of the Exchange Value is
presented for the Partnership in the tables and discussions below.

EXCHANGE VALUE COMPONENTS

         The following table sets forth the Exchange Value components,
determined as of September 23, 1998:

<TABLE>
<S>                                                        <C>
Fair market value of Proved Reserves

         Exchange Value                                    $11,500,000
</TABLE>

(1)      As determined by Gruy.

(2)      Estimated based on unaudited September 30, 1998 financial statements
         prepared by Middle Bay.

(3)      As determined by Middle Bay.

         The estimated net book value of the Partnership as of September 30,
1998 was $10,171,417 after deducting 1998 distributions aggregating $3,068,166.
The current net assets are based upon the Partnership's September 30, 1998
unaudited financial statements, respectively, maintained in accordance with
applicable provisions of the Partnership Agreement.

         Middle Bay has assigned nominal value to the Partnership's equipment
(comprised of oil and gas production and processing facilities) on the
assumption that its salvage value at the end of the commercial lives of acquired
wells will approximate the cost of plugging and abandoning the wells, contingent
liabilities which Middle Bay is assuming. Middle Bay also believes that valuing
the current assets and liabilities of the Partnership at their book value as of
September 30, 1998 is appropriate to reflect the fair market value of these
items in the stated amounts reflected in the Partnership's unaudited balance
sheet as of that date.

         The calculation of the fair market value of the Partnership's Proved
Reserves for the purpose of determining the Exchange Value was estimated using
the income approach as opposed to the market data approach because it is
difficult to identify sales of oil and gas properties that are comparable in net
reserves, product prices, location, operating expenses and operator expertise.
For the proved producing properties, the discounted future net revenue is
reduced to a fair market value by multiplying by a suitable fraction that
accounts for the risk associated with an investment. For proved developed
nonproducing and proved


                                     - 36 -
<PAGE>   49
undeveloped reserves, the present value of the required capital is added to the
discounted future net revenue, a suitable risk factor is applied, and the
present value of the capital is subtracted from that value. This approach
assumes that the capital is invested with certainty and the resulting cash flow
stream is burdened with the uncertainty. In all cases, the payout time and the
internal rate-of-return for each fair market value estimate are computed and
compared with that which a rational investor would expect.

         The net quantities of Proved Reserves attributable to the Partnership's
interest in its wells, together with the estimated fair market value of those
reserves, were estimated as of September 23, 1998 in the report prepared by
Gruy. A copy of the report, which also sets forth the criteria and assumptions
used in evaluating the Partnership's Proved Reserves, is included herewith in
Exhibit "A."

         There are numerous uncertainties inherent in estimating quantities of
Proved Reserves. Gruy prepared the data based on their evaluation of the total
Proved Reserves attributable to all of the wells in which the Partnership had an
interest as of September 23, 1998. Estimates by other independent petroleum
engineers could vary from the Gruy Report's estimates and could result in higher
or lower valuations.

         The estimates of the Partnership's future gross revenues attributable
to its estimated Proved Reserves as of September 23, 1998 were calculated based
on natural gas and crude oil prices in effect on that date with certain
escalations. Those prices had a weighted average of $2.71 per Mcf for natural
gas and $16.47 per Bbl for oil.

         Future operating and development costs were based on the Partnership's
operating and development costs as of September 23, 1998 and with certain
escalations as described in the Gruy Report. Future severance (production) and
ad valorem (property) taxes were calculated using rates prevailing at September
23, 1998. The estimated future gross revenues, future operating and development
costs and production taxes were allocated to the Partnership in accordance with
its interest in oil and gas properties, taking into account applicable
reversionary and overriding royalty interests.

         The present values of the estimated net cash flows attributable to the
Partnership's Proved Reserves were calculated by discounting the future net cash
flows to present value at the rate of 10% per year, as adjusted in accordance
with the Partnership Agreement. The discount factor is intended to reflect the
timing of future net cash flows. No further discount or risk adjustment was
applied. Present value, regardless of the discount rate used, is materially
affected by assumptions as to timing of and prices obtained for future
production, which may prove to have been inaccurate.

         The Gruy Report is included as Exhibit "A" to this Prospectus.
Estimates of the Partnership's Proved Reserves and of the present value of
future net cash flows from the reserves are estimates only and are based on
numerous assumptions and conditions of those estimates.

         In determining the value attributed to general intangibles, Middle Bay
evaluated the success to date of the Partnership, total consideration paid to
date to the participants and the value to Middle Bay of dissolving and
liquidating the Partnership so that Middle Bay can focus on its current
operations and reduce the administrative burdens associated with operating the
Partnership. From inception through October, 1998,


                                     - 37 -
<PAGE>   50
the Partnership has made cash distributions to participants aggregating
$6,455,865, or approximately $5.85 per Unit.

         The Exchange Value will not be adjusted to reflect changes after
September 23, 1998 in the present value of the estimated future net cash flows
attributable to the Partnership's Proved Reserves. No adjustments will be made
to the Exchange Value due to changes in demand for or costs or prices of oil and
gas that differ from the assumptions employed or other market-related events
after September 23, 1998, although those could affect the value of the Units.

FAIRNESS OPINION

         Harris Webb & Garrison, Inc. ("HWG") was retained by the Board of
Directors of Middle Bay to render an opinion (the "Fairness Opinion") to the
Board as to the fairness from a financial point of view of the consideration to
be received by the holders of Units in the Exchange. On October 15, 1998,
pursuant to Middle Bay's request, HWG delivered its written opinion to the Board
of Directors of Middle Bay to the effect that, as of the date of the opinion,
the consideration to be received by Unitholders of the Partnership in the
Exchange was fair to such holders from a financial point of view. HWG has
consented to the use of its name and the Fairness Opinion in this Prospectus.
The Fairness Opinion is included as Exhibit "D" to this Prospectus.

         The summary of the Fairness Opinion set forth in this Prospectus is
qualified in its entirety by reference to the full text of such opinion.
Unitholders are urged to read the opinion in its entirety for assumptions made,
procedures followed, other matters considered and limits of the review by HWG.
In arriving at its opinion, HWG considered a possible range of fair value with
respect to the Units and made its determination as to the fairness of the
consideration (shares of Series C Preferred Stock) based on the financial and
comparative analyses described below.

         The HWG Fairness Opinion was prepared for the Board of Directors of
Middle Bay and is directed only to the fairness, from a financial point of view,
as of October 15, 1998, of the consideration to be received by Unitholders in
the Exchange. The HWG Fairness Opinion does not constitute a recommendation to
any Unitholders as to how to respond to the Proposal. In addition, HWG was not
asked to opine as to, and its opinion does not address, the underlying business
decision of the Board of Directors of Middle Bay or the General Partner to
proceed with or to effect the Exchange, nor did HWG participate in the
determination of the terms of the Proposal.

         In connection with rendering its opinion, HWG, among other things: (i)
reviewed the Proposal in its substantially final form; (ii) reviewed Middle
Bay's and the Partnership's Annual Reports on Form 10-KSB for the fiscal year
ended December 31, 1997 and their respective Quarterly Reports on Form 10-QSB
for the periods ended March 31, 1998 and June 30, 1998; (iii) reviewed the Gruy
Report, along with certain operating and financial information provided to HWG
by management of the General Partner relating to the Partnership's properties,
business and prospects; (iv) discussed the Gruy Report with representatives of
Gruy; (v) met with certain members of the General Partner's senior management to
discuss their operations, historical financial statements and future prospects;
(vi) reviewed certain operating and financial


                                     - 38 -
<PAGE>   51
information provided to HWG by management of Middle Bay relating to its
properties, business and prospects; (vii) reviewed the historical prices and
trading volumes of Middle Bay common stock; (viii) reviewed publicly-available
financial data and stock market performance data of companies that it deemed
generally comparable to Middle Bay; (ix) reviewed the terms of recent
acquisitions of publicly-held oil and gas assets and entities that it deemed
generally comparable to the Partnership; (x) reviewed the terms of outstanding
series of preferred stock which HWG believes to be comparable to the proposed
terms of the Series C Preferred Stock; and (xi) conducted such other studies,
analyses, inquiries and investigations as it deemed appropriate.

         In rendering its opinion, HWG assumed, without independent
verification, the accuracy, completeness and fairness of all financial and other
information that was available to it from public sources or that was provided to
it by Enex, Middle Bay, Gruy or their representatives. HWG relied upon the
assurances of Enex and Middle Bay that they have no actual knowledge of any
facts that would make the Gruy Report or other information they provided to HWG
incomplete or misleading. Unitholders are cautioned, however, that the
valuations concerning the Partnership contained in the Gruy Report and the
information regarding Middle Bay's future prospects provided to HWG by Middle
Bay management are based on numerous variables and assumptions that are
inherently uncertain. These include, without limitation, general economic
conditions and competitive conditions within the oil and gas industry and
potential changes (which generally cannot be predicted) in the market prices of
oil and gas, and that the inclusion of such information should not be regarded
as an indication that Enex, Middle Bay or any persons who received such
information consider it other than an estimate of future events.

         The Fairness Opinion is necessarily based on economic, market,
financial and other conditions as they existed on, and on the information made
available to it as of, the date of such opinion. It should be understood that,
although subsequent developments may affect its opinion, except as agreed upon
by Middle Bay, HWG does not have any obligation to update, revise or reaffirm
its opinion.

         In arriving at its opinion, HWG did not perform any independent
appraisal of the assets of the Partnership or Middle Bay. In analyzing the value
of proved reserves of the Enex Partnership, HWG relied substantially on the
evaluations of H.J. Gruy and Associates in the Gruy Report. HWG also reviewed a
reserve evaluation prepared by management of Middle Bay using pricing
assumptions set forth in SEC rules prepared at the request of HWG as of
September 30, 1998. While HWG viewed these evaluations as important to their
fairness analysis, HWG did not view them as conclusive as to value of the Enex
Partnership, but rather one of many indications of value analyzed by HWG.

         The following is a summary of the most significant factors considered
and the principal financial analyses performed by HWG to arrive at its opinion
dated October 15, 1998.

         -        Value Range Comparison. HWG's fairness analysis was primarily
                  that the estimated fair market value range of "value received"
                  by a public Unitholder was within a range of value reasonably
                  equivalent to the estimated fair market value range of "value
                  surrendered." HWG's fair market value range for "value
                  received" was estimated to be $8.51 - $10.43 per Unit and
                  "value surrendered" was estimated to be $9.48 - $11.84 based
                  upon a Gruy Report


                                     - 39 -
<PAGE>   52
                  fair market value of $10.4 million for the Enex Partnership
                  oil and gas reserves. HWG also noted that if the Gruy Report's
                  orderly liquidation value of $8.9 million is substituted for
                  the $10.4 million value, the HWG range for "value surrendered"
                  is reduced to $8.29 - $10.29 per Unit.

         -        Discounted Cash Flow Analysis Contained in the Gruy Report. 
                  HWG considered the present value of $14,140,959 (approximately
                  $12.82 per Unit) of the future cash flows that the proved 
                  reserves of the Partnership could be expected to generate 
                  after October 1, 1998 based on the Gruy Report.

         -        Analysis of Certain Other Publicly-Held Oil and Gas
                  Partnerships. HWG compared selected operating and financial
                  ratios for the Partnership to the corresponding data and
                  ratios for selected oil and gas entities whose securities are
                  publicly held and which HWG believed were comparable in
                  certain respects to the Partnership. These entities were
                  selected for comparison as they are oil and gas entities with
                  similar properties and business characteristics to the
                  Partnership. HWG calculated the market capitalization and
                  market value for each of the following publicly-traded
                  companies: Abraxas Petroleum Corporation, Coho Energy, Inc.,
                  Costilla Energy, Inc., Key Production Company and Wiser Oil
                  Company (collectively, the "Comparable Companies"). For this
                  purpose, HWG defined "market capitalization" as market value
                  of the relevant company's common equity plus total debt less
                  excess cash and cash equivalents. HWG calculated the market
                  capitalization of each of the Comparable Companies as a
                  multiple of each such company's December 31, 1997 proved
                  reserves, the latest twelve months earnings (as of June 30,
                  1998) before interest, taxes, depreciation, depletion,
                  amortization, impairments and cost ("EBITDX") and the present
                  value of future net revenues of proved reserves (before taxes)
                  discounted at 10% (SEC method pricing) ("SEC PV 10%). The
                  multiples yielded by such calculations for the Comparable
                  Companies were (i) with respect to proved reserves, between
                  $0.60 per Mcfe and $1.06 per Mcfe, (ii) with respect to the
                  latest twelve months EBITDX, between 4.1x and 8.8x, and (iii)
                  with respect to the SEC PV 10% Value, between 86% and 130%.
                  Applying these multiples to the Partnership yielded a value
                  range of $11.6 to $16.3 million for 100% of the Partnership
                  equity (approximately $10.52 to $14.78 per Unit).

                  Because of the inherent differences between the businesses,
                  operations and the prospects of the Partnership and the
                  businesses, operations and prospects of the Comparable
                  Companies and the recent significant changes in the oil and
                  gas markets, HWG believed that it was inappropriate to, and
                  therefore did not, give significant weight to the quantitative
                  results of this analysis of comparable companies.

         -        Comparable Convertible Preferred Stocks. HWG reviewed 22
                  publicly-traded convertible preferred stocks and compared
                  yield and conversion premiums to the new Series C Preferred
                  Stock. When compared to these publicly-traded convertible
                  preferred stocks, the proposed dividend yield of 10% and the
                  anticipated conversion premium of approximately 42 - 66% for
                  the new Series C Preferred Stock appear to indicate that the
                  fair market value of the new Preferred would be in the range
                  of approximately $4.00 to $5.00 per share.

         -        Comparable Transactions. HWG reviewed certain transactions,
                  but none were believed significantly comparable to the
                  Exchange to provide meaningful analysis. HWG did note,
                  however, a recent investment of $130 million in Triton Energy
                  made with an 8% preferred convertible at a premium of
                  approximately 20 - 50%.

         In addition to the financial analyses set forth above, HWG considered a
number of qualitative factors in arriving at its opinion, including, without
limitation, the following: (i) the Unit's limited liquidity and voting rights;
(ii) the potential capital appreciation of the Middle Bay common stock
underlying the Series C Preferred Stock; (iii) the predictable income stream of
the Series C Preferred Stock; (iv) the greater number and diversity of
properties of Middle Bay resulting from the Exchange; and (v) the priority of
the liquidation preference of the Series C Preferred Stock with respect to
Middle Bay common stock.

         The summary set forth above is not a complete description of the
analyses performed by HWG. Preparation of the Fairness Opinion involved various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances.
Notwithstanding the separate factors summarized above, HWG believes that its
analyses must be considered as a whole and that selecting portions of its
analyses and the factors considered by it, without considering all analyses and
factors, would create an incomplete view of the evaluation process underlying
its Fairness Opinion. In performing its analyses, HWG made numerous assumptions
with respect to oil and gas industry performance, market prices for oil and gas
and economic conditions and other matters. The analyses performed by HWG are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses.

         The Board of Directors of Middle Bay selected HWG as its financial
advisor because HWG is a regionally recognized investment banking firm with
substantial experience in assignments similar to that undertaken with regard to
evaluating the Exchange. As part of its investment banking business, HWG is
regularly engaged in the valuation of business and securities in connection with
mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes.

         Pursuant to an engagement letter with Middle Bay, HWG will be paid
$40,000 from Middle Bay for rendering the Fairness Opinion. Middle Bay has also
agreed to reimburse HWG for its reasonable out-of-pocket expenses, including the
reasonable fees and expenses of its legal counsel, and to indemnify HWG against
certain liabilities arising out of or in connection with the services rendered
by HWG under the engagement, including liabilities under federal securities
laws. The terms of the fee arrangement with HWG, which are customary in
transactions of this nature, were negotiated at arms length between Middle Bay
and HWG. HWG has performed financial advisory services for Middle Bay in recent
months, for which it was paid an advisory fee of $20,000 by Middle Bay. As part
of these services, HWG performed a financial evaluation of Middle Bay. As a
result of that evaluation, HWG issued a research report and buy recommendation
with respect to Middle Bay common stock.

COMPARISON OF EXCHANGE VALUE WITH VALUES USED
IN 1997 PARTNERSHIP ROLL-UP

         H.J. Gruy & Associates, Inc. ("Gruy"), an independent petroleum
engineering firm, was engaged by Middle Bay and the General Partner to make a
fair market evaluation of the Partnership's oil and gas reserves as of October
1, 1998. Gruy is the same engineering firm which estimated the oil and gas
reserves for the Partnership and each of the Predecessor Partnership's
properties in connection with the 1997 consolidation of the Predecessor
Partnerships into the Partnership (the "1997 Roll-up"). Gruy's income approach
to determining the fair market value of Proved Reserves for the Partnership for
the Exchange Offer was the same as for each of the partnerships which were
consolidated in 1997 to form the Partnership (the "Predecessor Partnerships") in
connection with the 1997 Roll-up. The income approach requires the estimation of
reserves, identification of their categories (proved, probable and possible), a
cash flow projection and the proper allocation of risk factors. See the Gruy
Report included herewith as Exhibit A to this Prospectus. However, Gruy assigned
no fair market value to the categories of probable and possible reserves for the
Predecessor Partnerships, but did assign a value for those categories of
Partnership reserves for the Exchange Offer. The aggregate fair market value
assigned by Gruy to the Predecessor Partnerships' reserves for purposes of the
1997 Roll-up was $13,591,585, while the present fair market evaluation of the
Partnership's reserves is $10,380,000. To the extent that the fair market
evaluation for the Partnership's present estimated reserves differs materially
from the fair market valuation of the Predecessor Partnerships' reserves in
1997, the primary causes of such changes are the production and sale of oil and
gas production and properties by the Partnership, the decline in the market
prices for oil and gas and changes in debt and capital due the General Partner
over the past 12 months.

         The fair market valuation for the oil and gas reserves for the Exchange
Offer and the 1997 Roll-up were $10,380,000 and $13,591,585, respectively. The
table below presents the pricing parameters used by Gruy in its determination of
the value of the oil and gas reserves.

         The indebtedness of the Predecessor Partnerships to the General Partner
was substantially greater at the effective date of the 1997 Roll-up --
$2,447,191 versus $238,717. As of June 30, 1997, the current indebtedness to the
General Partner consisted of $1,975,137 in expense advances and $472,056 for the
General Partner's net revenue interest in certain of the Predecessor
Partnerships' wells.

         The General Partner's capital balance was much greater at the effective
date of the 1997 Roll-up -- $1,816,084 versus $44,940. For the 1997 Roll-up, the
General Partner's capital balance was created entirely by cash transactions
(i.e., cash revenues received less cash expenses paid) and, therefore,
represented undistributed cash earnings.

         The following is a comparison of the Exchange Offer with the 1997
Roll-up. The 1997 Roll-up exchange value assumes maximum acceptance and the
issuance of 1,130,400 Units to the limited partners of the Partnership. The 1997
Roll-up resulted in the issuance of 1,102,631 Units. Since July, 1997, the
limited partners have received cash distributions of approximately $5.85 per
Unit.

</TABLE>


                         REASONS FOR THE EXCHANGE OFFER

RECOMMENDATION OF THE GENERAL PARTNER

         Middle Bay and the General Partner, acting together, have initiated and
proposed the Exchange Offer and recommend approval of the Proposal. The decision
to recommend approval of the Exchange Offer is based on the conclusion that the
Exchange will be more beneficial to Investors than the alternatives of
continuing the Partnership or liquidating all of the assets of the Partnership
and that the terms of the Exchange Offer and related Proposal, including the
method used to determine the Exchange Value and the procedures involved in the
Proposal, are both fair and appropriate.

         Middle Bay and Enex, acting together in reaching the conclusion to
recommend that each of the Investors accept the Exchange Offer and approve the
Proposal, considered a number of factors, including, without limitation, the
following:


                                     - 43 -
<PAGE>   56
                  (a) The fiduciary duties owed by Middle Bay and Enex to the
Unitholders. Both Middle Bay and Enex considered their fiduciary duties to the
Unitholders and their respective shareholders and the inherent conflicts of
interest each has in initiating and recommending acceptance of the Exchange
Offer. See "Recommendations of the Boards of Directors of Middle Bay and Enex,"
"Fiduciary Duties of the General Partner and Middle Bay" and "Conflicts of
Interest," below.

                  (b) The financial condition, results of operations and cash
flows of Middle Bay and the Partnership, both on a historical and a prospective
basis. In this regard, the General Partner believes that Middle Bay
historically, and on a pro-forma basis after acquisition of the Partnership's
assets, has been and is likely to continue in the future to be a growth company,
with prospects that could continue to show significant increases in results of
operations and cash flow, resulting in potential future appreciation in the
price of the common stock underlying the Series C Preferred shares. See
"Selected Financial Data - Middle Bay," "Selected Financial Data - Partnership"
and "Selected Pro Forma Consolidated Financial Information (Unaudited)."

                  (c) The consideration to be received by the Partnership's
Investors in connection with the Exchange Offer represents a significantly
higher distribution to Investors than could be expected from the present value
of continued total cash distributions or the distributions to Investors in
liquidation. Specifically, the General Partner estimates that cash distributions
for the life of the Partnership, if the Partnership were to continue operations,
would be $10.28 per Unit and would have a present value (using a 10% discount
rate) of $6.82 per Unit. See "Alternatives to the Exchange."

                  (d) Dividends with respect to the Series C Preferred. The 10%
dividend rate on the Series C Preferred will result in Investors receiving
annual cash dividends of approximately $1.04 per Unit exchanged compared to cash
distributions from the Partnership of $4.02 per Unit during the 12-month period
ended September 30, 1998. However, the General Partner believes that the cash
distributions to Investors from the Partnership will likely decrease rapidly as
the remaining oil and natural gas reserves are depleted. See "Alternatives to
the Exchange."

                  (e) Current market conditions and historical market prices,
volatility and trading information with respect to the common stock of Middle
Bay compared to the lack of a trading market for the Partnership Units. In this
regard, the potential growth rate and market price to earnings and cash flow
potential of Middle Bay were considered. Middle Bay believes that Investors who
choose to convert their Preferred Shares will receive the benefit of any future
growth in the value of their equity interest in Middle Bay rather than receiving
cash distributions from the Partnership, which are likely to decrease rapidly as
the remaining oil and natural gas reserves of the Partnership are depleted. See
"Price Range of Middle Bay Common Stock; Dividends and Distributions."

                  (f) Potential Liquidity of the Series C Preferred and the
underlying common stock of Middle Bay compared to the lack of liquidity of the
Partnership Units. Middle Bay has applied for listing the Series C Preferred for
trading on the NASDAQ Small Cap Stock Market, subject to approval, although
there can be no assurance that an active trading market will develop following
the Exchange. The common stock of Middle Bay has an active trading market on
NASDAQ Small Cap Stock Market. The Partnership


                                     - 44 -
<PAGE>   57
Units have no liquidity, and the Partnership Agreement restricts transfer of the
Partnership Units. See "Price Range of Middle Bay Common Stock; Dividends and
Distributions."

                  (g) The terms and conditions of the Exchange Offer, including
the amount of consideration to be paid to the Investors and the form of the
consideration, the parties' representations, warranties, covenants and
agreements, and the conditions to their respective obligations set forth in the
Exchange Offer. Middle Bay believes that the terms and conditions of the
Exchange Offer are favorable to the Partnership's Investors. In reaching this
conclusion, Middle Bay noted the nature of the representations and warranties,
the limited number of conditions in the Exchange Offer and the payment by Middle
Bay of all transaction costs and the assumption by Middle Bay of all Partnership
liabilities, including contingent and unforeseen liabilities. Middle Bay
believes that in the absence of extraordinary or unforeseen circumstances, there
is a high likelihood that the transaction will be completed, subject to the
requisite approval of the Partnership's Investors. Accordingly, Middle Bay
believes that the terms of the Exchange Offer are more favorable to the
Investors than purchase and sale agreements that are customarily entered into.
See "Alternatives to the Exchange" and "The Exchange Offer and the Proposal."

                  (h) The review of other alternatives for the Partnership,
including possible sales of Partnership assets to third parties, continued
operation of the Partnership and liquidation of the Partnerships. Middle Bay did
not believe that the sale of all of the assets of the Partnership was as
attractive to the Partnership as the Exchange Offer because of the value of the
reserves being offered by Middle Bay in the Exchange Offer (as supported by the
Gruy Report and the Fairness Opinion), the uncertainty that a third-party
purchaser or purchasers could be found for all of the assets and, if found,
whether a purchase and sale agreement could be negotiated on terms favorable to
the Partnership. Middle Bay and Enex also considered that the Partnership's
reserve estimates could be undervalued. Middle Bay did not believe that
liquidation of the Partnership was as attractive to the Partnership as the
Exchange Offer because the estimated liquidation value of the Partnership is
substantially less than the consideration to be received by each of the
Investors under the Exchange Offer. Middle Bay did not believe that the
continued operation of the Partnership was as attractive to the Partnership as
the Exchange Offer because Middle Bay believes that the continued cash
distributions made by the Partnership are likely to decrease rapidly as the
remaining oil and natural gas reserves are depleted. See "Alternatives to the
Exchange."

                  (i) The uncertainties and risks in the oil and gas industry
and the possibility that changes in the industry or continued volatility of oil
and gas prices could have a significantly greater effect on the Partnership due
to the size of the Partnership compared to Middle Bay and the greater
diversification of oil and gas properties and prospects of Middle Bay. Middle
Bay also considered the possibility that such uncertainties could be
disadvantageous to Middle Bay and advantageous to the Partnership. See "Risk
Factors and Material Considerations."

                  (j) The tax consequences to the Partners in connection with
the Exchange Offer and liquidation of the Partnership. Although the tax
consequences to some of the Partners may be unfavorable, Middle Bay believes
that the benefits of the transaction outweigh any such unfavorable consequences,
on balance, for all of the Partners. See "Material Federal Tax Consequences."


                                     - 45 -
<PAGE>   58
                  (k) The benefits to Middle Bay of acquiring the Partnership's
properties. Middle Bay expects to benefit from the Exchange because the
Partnership's properties will add to Middle Bay's cash flow, increase Middle
Bay's oil and gas reserves and thereby increase its borrowing base for purposes
of securing Middle Bay's bank credit lines, thereby facilitating debt-financed
future acquisitions of oil and gas properties. Middle Bay also expects to
significantly reduce the general and administrative expenses of Enex associated
with management of the Partnership as a separate entity. See "Risk Factors and
Material Considerations Valuation Conflict of Interest; Benefits of Exchange to
Middle Bay."

         In view of the wide variety of factors considered in connection with
its evaluation of the terms of the Exchange Offer, Middle Bay did not find it
practicable to, and did not, quantify or otherwise attempt to assign relative
weights to the specific factors considered in reaching its determination.

         MIDDLE BAY AND THE GENERAL PARTNER OF THE PARTNERSHIP HAVE
DETERMINED THAT THE EXCHANGE IS FAIR AND IN THE BEST INTERESTS OF THE
PARTNERSHIP AND ITS UNITHOLDERS AND RECOMMEND THAT THE UNITHOLDERS OF THE
PARTNERSHIP TENDER THEIR PARTNERSHIP INTERESTS AND CONSENT TO THE PROPOSAL.

ALTERNATIVES TO THE EXCHANGE

         Middle Bay's analysis of the most probable results of continuing the
Partnership indicate that, while continuing the Partnership would avoid the
risks associated with the ownership of Series C Preferred in Middle Bay,
Investors will receive potentially greater values by participating in the
Exchange than the values they would derive from this alternative. Middle Bay
estimates that continuing the Partnership under market and operating conditions
prevailing in 1998 would likely generate decreasing annual distributions to
Investors of $3.22 per Unit in 1998, $1.33 in 1999, $1.07 in 2000 and $.81 in
2001. Middle Bay estimates that the remaining economic life of the Partnership
is six years, based upon projected production volumes and cash flows from the
Gruy Reserve Report.

         Middle Bay also believes that, while liquidating the Partnership would
provide an immediate cash return and avoid the risks associated with owning
Middle Bay Series C Preferred, the Exchange will provide Investors with greater
values than they would likely receive in liquidation of the Partnership. Middle
Bay's liquidation analysis reflects an estimated liquidation value of
approximately $9,881,000, or $8.96 per Unit. For purposes of determining the
general and administrative costs to the Partnership during the liquidation
process, Middle Bay estimated that general and administrative expenses would
approximate the general and administrative expenses incurred by the Partnership
during the quarter ended June 30, 1998 on an annualized basis.

         The following tables summarize the results of Middle Bay's liquidation
analysis in comparison to the Exchange Value for the Partnership Units
determined by Middle Bay. The table also includes valuation data derived from
Middle Bay's analysis of continuing the Partnership. Middle Bay did not
undertake its continuation analysis for the purpose of valuing the Partnership,
but solely to illustrate the likelihood of decreasing distributions based on
production declines as projected in the Gruy Report and oil and gas prices


                                     - 46 -
<PAGE>   59
at September 30, 1998. However, because SEC disclosure standards for roll-up
transactions require a comparison of the value of the consideration offered in
the transaction with the value of the consideration estimated for each
alternative to the transaction, the tables also reflect the results of extending
Middle Bay's continuation analysis for the balance of the estimated life of the
Partnership's Proved Reserves, and discounting the projected stream of
distributions to present value at the same 10% discount rate used in Middle
Bay's liquidation analysis to account for the timing of cash flows as well as
production and concentration risks.

         General Partner's interest. The continuation analysis assumes continued
         distributions to the General Partner pursuant to the terms of the
         Partnership Agreement.

(2)      The assumed natural gas and oil prices are the prices used for
         preparation of the Partnership's reserve report dated September 23,
         1998 and as of October 1, 1998, with escalation of prices and costs as
         set forth in the report. The continuation analysis was calculated based
         upon Middle Bay's estimate of the remaining economic life of the
         Partnership, estimated to be six years.

         The actual amount that Investors would receive if the Partnership
continued its operations would depend on production levels and various other
factors (prices, costs, etc.), which cannot be predicted with certainty. In
addition, the actual amount that Investors would receive under either of the
alternatives to the Exchange would depend on future oil and gas prices. To the
extent that future prices for those commodities are materially higher or lower
than the pricing assumptions made by the General Partner, those fluctuations
would likely have a similar effect on the operating results, distribution rates
and market value of the Partnership Units, largely negating the effect of price
changes on a comparison between the Exchange and either alternative of
continuing the Partnership or liquidating its assets. In addition, Middle Bay
believes that liquidating the Partnership would deprive Investors of the
opportunity to benefit from any future upturn in oil and gas prices.

BENEFITS OF CONTINUED OPERATIONS

         Continuing to operate the Partnership could benefit Investors by
avoiding many of the risks associated with owning Middle Bay Series C Preferred
or, assuming conversion, the underlying common stock. In addition, Middle Bay
does not pay cash dividends on its shares of common stock and does not
anticipate paying dividends in the foreseeable future. However, Middle Bay's
continuation analysis reflects a present value (using a 10% discount rate) that
is $3.46 per Unit (33%) below the Exchange Value.


                                     - 47 -

Accordingly, Middle Bay believes that Investors are likely to receive less value
if the Partnership continues in its present form than they would receive by
participating in the Exchange. While this conclusion is supported by Middle
Bay's analysis of continuing the Partnership, there can be no assurance that the
Exchange will be more beneficial to Investors than continuing the Partnership.

(3)      Includes estimated net value of remaining assets.

(4)      Middle Bay's continuation analysis estimates that the remaining
         economic life of the Partnership is six years. This analysis assumes
         that total revenues, production taxes and lease operating expenses will
         be consistent with those assumptions set forth in the Gruy Report dated
         September 23, 1998 and that annual general and administrative expenses
         will be consistent with actual annualized general and administrative
         expenses incurred by the Partnership for the three months ended June
         30, 1998.

BENEFITS OF LIQUIDATION

         If the Partnership liquidated its assets and completed a dissolution
upon the sale of its assets for cash, the Investors would benefit by receiving
an immediate cash return without continuing to be subject to the risks of owning
Middle Bay Series C Preferred and risks of participation in oil and gas
operations. In addition, if the Partnership were liquidated in a cash
transaction, Investors could reinvest the proceeds in similar or different
investments. For the reasons described herein, however, Middle Bay believes that
liquidating the Partnership would not provide Investors with greater values than
those they would receive in the Exchange. Although Middle Bay made various
assumptions that it believes to be reasonable in conducting the liquidation
analysis supporting this conclusion, there can be no assurance that those


                                     - 48 -
<PAGE>   61
assumptions would ultimately prove to be correct and that proceeds of a cash
sale would not exceed the value of the Series C Preferred issuable in the
Exchange.

         Middle Bay's and Enex's decision to recommend approval of the Proposal
is supported by Gruy's liquidation analysis, reflecting an estimated liquidation
value of $9,881,000, or $8.96 per Unit, and the Fairness Opinion rendered by
HWG. Based on these factors, Middle Bay and Enex have concluded that, while a
sale of the Partnership's properties as a whole would provide an immediate cash
return to Investors, it would likely result in valuations by an unaffiliated
bidder or bidders below the Total Exchange Value, and further, any cash received
would likely be equal to or less than the liquidation value after payment of
transaction costs and costs associated with liquidation and dissolution.
Additionally, Middle Bay will assume all contingent and unknown liabilities of
the Partnership, as well as sole responsibility for payment of all transaction
costs associated with the Exchange Offer, allowing distribution of consideration
without deduction for such costs. Middle Bay believes it unlikely that a third
party would offer to purchase the Partnership's assets at fair market value and
also assume responsibility for payment of transaction costs and assumption of
all contingent and unknown liabilities.

                                     - 49 -
<PAGE>   62
Middle Bay's liquidation analysis assumed that a majority in Interest of the
Investors would approve the sale of all or substantially all of the
Partnership's assets, as required under the Partnership Agreement. Based on this
analysis, the General Partner concluded that Investors would benefit more from
the Exchange than a potential liquidation of the Partnership.

OTHER CONSIDERATIONS AS ALTERNATIVES

         The General Partner and Middle Bay also considered whether assessing
the Unitholders for voluntary additional capital contributions and/or having the
Partnership borrow funds were feasible alternatives to provide capital for
further development activities. Both of the foregoing alternatives were rejected
as impractical and inconsistent with the business objectives of the Partnership.

APPROVAL OF THE BOARD OF DIRECTORS OF MIDDLE BAY;
REASONS FOR THE APPROVAL

         At a meeting held on November 24, 1998, the Board of Directors of
Middle Bay unanimously approved the Exchange Offer and the authorization and
issuance of Middle Bay Series C Preferred in connection with the Exchange. The
Alabama Corporation Law does not require that Middle Bay stockholders approve
the Exchange Offer or the issuance of Middle Bay Series C Preferred (or the
underlying common stock), and no such approval is being sought.

         In reaching its conclusion to approve the Exchange Offer, the Board of
Directors of Middle Bay determined that the purchase of Partnership assets by
Middle Bay is consistent with and in furtherance of the long-term business
strategy of Middle Bay. In addition, the Board of Directors believes that the
Exchange Offer provides Investors in the Partnership the opportunity to benefit
from the continued growth of Middle Bay and consideration in excess of the
liquidation value or continuation value of the Partnership. In addition, the
Board believes that dissolution of the Partnership upon consummation of the
Exchange and adoption of the Proposal by the Partnership will allow Middle Bay
to focus its resources on the core assets and projects of Middle Bay and will
provide Middle Bay with the benefits of increasing its reserves and cash flow
and thereby increasing its borrowing base (reserves which qualify as security
for bank loans), which is expected to facilitate bank financing of future
acquisitions of oil and gas properties.

FIDUCIARY DUTIES OF THE GENERAL PARTNER AND MIDDLE BAY

         Middle Bay's and Enex's fiduciary duties to Unitholders include legal
responsibilities of loyalty, care and good faith. Neither Enex, as the General
Partner of the Partnership, nor Middle Bay, as the parent of Enex, may profit by
any conduct or transaction in contravention of their fiduciary obligations to
the Investors. Rights of action by or on behalf of the Investors for any breach
of these duties are provided under most state limited partnership or other laws.
Under New Jersey law, which is the choice of law provided in the Partnership
Agreement, a limited partner may bring action against a general partner, upon a
showing of the breach of its fiduciary duty, to recover his capital contribution
or to seek an accounting and dissolution of the partnership. While a general
partner would have the burden of dispelling all doubts concerning its conduct,
simple negligence or an error in judgment not amounting to a breach of fiduciary
duty would


                                     - 50 -
<PAGE>   63
constitute a defense to the limited partner's actions under New Jersey law.
Middle Bay and Enex each believes that it has complied with its fiduciary duties
in the management of the Partnership and in connection with the Exchange Offer.

         Under New Jersey law, except as described below, if a nonconsenting
Investor believes that adoption of the Proposal or consummation of the Exchange
would constitute a breach of the General Partner's fiduciary duties, the
Investor could institute legal action against Middle Bay and/or Enex to enjoin
the Exchange or implementation of the Amendment contemplated by the Proposal or
to recover damages resulting from the consummation of the Exchange. In
appropriate circumstances, a limited partner may institute a class action
against its general partner on behalf of himself and the other similarly
situated limited partners or a derivative action against a general partner on
behalf of the partnership to recover damages for a breach of a general partner's
fiduciary duties. This is a developing area of the law, and Investors who have
questions concerning the General Partner's duties should consult with their own
legal counsel.

         The Partnership Agreement provides that the General Partner and its
affiliates (including Middle Bay) will not be liable to the Partnership or the
Investors for errors of judgment or any acts or omissions that do not constitute
negligence or misconduct. In addition, the Partnership Agreement provides
generally that, to the extent permitted by law, the Partnership will indemnify
the General Partner and its affiliates providing services on behalf of the
Partnership against judgments and amounts paid in settlement, plus costs and
expenses (including reasonable attorneys' fees and expenses) actually and
reasonably incurred, if the indemnitee acted in good faith and in a manner
reasonably believed to be in, or not opposed to, the best interests of the
Partnership. In the opinion of the SEC, indemnification for liabilities arising
under the Securities Act is against public policy and, therefore, unenforceable.

CONFLICTS OF INTEREST

         Middle Bay, as controlling shareholder of the General Partner of the
Partnership, has an inherent conflict of interest in the determination of the
Exchange Value. Both the General Partner and Middle Bay owe a fiduciary duty to
Unitholders in the Partnership. In addition, Middle Bay and Enex owe a duty to
their respective stockholders, and Middle Bay owes a duty to the minority
shareholders of Enex. Middle Bay expects to benefit from the acquisition of the
Partnership's properties by its receipt of cash flow from the properties and the
addition to its borrowing base of the Proved Reserves of the Partnership which
is expected to facilitate bank financing of future acquisitions. While Middle
Bay believes that it has fulfilled its fiduciary obligations in the
determination of the Exchange Value which is supported, in part, by the Gruy
Report and the Fairness Opinion, no degree of objectivity or professional
competence can eliminate the inherent conflicts of interest. See "Reasons for
the Exchange Offer - Fiduciary Duties of Middle Bay and the General Partner" and
"Conflicts of Interest."

CERTAIN TRANSACTIONS BETWEEN THE PARTNERSHIP, ENEX AND MIDDLE BAY

         Enex, as General Partner and as a Unitholder of the Partnership, has
received $3,574,810 in total distributions from the Partnership since its
formation in 1997. These distributions included $3,403,404 attributable to
Enex's interest as a Unitholder and $171,406 attributable to its general
partnership interest. Enex does not receive any other compensation from the
Partnership as General Partner. Middle Bay, as


                                     - 51 -
<PAGE>   64
owner of 79.2% of Enex, benefits indirectly from the Partnership's distributions
to Enex. Since July 1997, on two occasions Enex has purchased for cash a total
of 39,826 Units from various Unitholders at prices ranging from $11.77 to $12.44
per Unit. These purchases by Enex of Units have been made in accordance with the
presentment and valuation procedures set forth in Article 6 of the Partnership
Agreement ("Right to Present Units for Purchase"). Under the procedures outlined
in such Article 6, the General Partner determined the purchase price of the
previously-acquired Units based upon an independent expert's estimate as of the
previous December 31st of the discounted present worth of future net revenues
attributable to the Partnership's interest in Proved Developed Reserves and
Proved Undeveloped Reserves, plus the value of other assets of the Partnership,
less liabilities attributable to the capital accounts of the Unitholders (the
"Presentment Price"). Summaries of the calculations used to determine the
Presentment Prices as of July 1, 1997 and as of January 1, 1998 are as follows:

Enex and Middle Bay believe that the Exchange Value of $10.43 per Unit is a fair
value in relation to the prices paid in previous purchases of Units by the
General Partner inasmuch as the Exchange Value was determined in a manner
consistent with the foregoing procedures supported by the Gruy Report and the
Fairness Opinion. The reserve reports prepared by Gruy for the July 1, 1997
Presentment Price determination were the same reports used in connection with
the 1997 Roll-up (see "Comparison of Exchange Value With Values Used in 1997
Partnership Rollup"). Gruy used the same methodology and approach for its
reserve report used by the Partnership for the January 1, 1998 Presentment Price
determination.

ACCESS TO INVESTOR LIST AND PARTNERSHIP RECORDS

         Enex will provide free of charge to any Investor, upon written request,
a current alphabetized listing of all names and addresses of Investors in the
Partnership. Investors are afforded this right under the Partnership Agreement
and federal and state law. Investors also have the right under the Partnership
Agreement to inspect the books and records of the Partnership at all reasonable
times in the offices of the General Partner, which are the offices of Middle Bay
in Houston, Texas.

executes an agreement with Middle Bay will be entitled to receive a fee from
Middle Bay. Total fees paid to all Soliciting Dealers are not expected to exceed
$30,000 in the aggregate.

         Middle Bay has agreed to indemnify Soliciting Dealers (if any) against
certain civil liabilities, including liabilities under the Securities Act. The
Soliciting Dealers may be deemed to be underwriters within the meaning of the
Securities Act.

ACCEPTANCE OF TENDERS

         On the Closing Date, subject to the satisfaction or waiver of the
conditions to the Exchange Offer, Middle Bay will accept all Partnership Units
properly tendered pursuant to the Exchange Offer. Middle Bay


                                     - 53 -
<PAGE>   66
will then tender these Partnership Units to Enex which will cause the assets of
the Partnership, subject to associated liabilities, to be withdrawn from the
Partnership and contributed to Middle Bay effective as of the Effective Date in
exchange for the Series C Preferred, which will be issued and delivered promptly
after the Closing Date.

         On the Closing Date, Middle Bay will cause certificates representing
the Series C Preferred issuable in the Exchange to be registered in the name of
holders who have accepted the Exchange Offer. Middle Bay will also cause a
certificate representing the shares of Series C Preferred that will be issued to
participants upon liquidation of the Partnership to be issued in the name of the
Partnership, pending dissolution, liquidation and winding up of the Partnership.
Immediately thereafter, Enex will cause the shares of Series C Preferred issued
in the name of the Partnership to be transferred into certificates representing
Series C Preferred registered in the names of the individual participants
remaining in the Partnership following liquidation.

SPECIAL REQUIREMENTS FOR CERTAIN INVESTORS

         Some of the Investors are entities, such as estates, trusts,
corporations, limited partnerships or general partnerships. With respect to a
Partnership Unit tendered by an Investor other than an individual, Middle Bay
may elect, at its option, to require that each Letter of Transmittal be
accompanied by evidence that the Investor has met all requirements of its
governing instrument, such as applicable partnership or joint venture
agreements, and is authorized to tender its Partnership Units under the laws of
the jurisdiction in which the entity was organized. With respect to most trusts,
including individual retirement accounts, Middle Bay expects to require only
that the named trustee (or authorized representative thereof) execute the Letter
of Transmittal.

REPRESENTATIONS AND COVENANTS

         Each Investor represents in the Letter of Transmittal that he has, and
will have as of the Closing Date, the right and authority to transfer his
Partnership Unit and that his Partnership Unit is free and clear of all liens,
encumbrances and adverse claims. The Letter of Transmittal also contains a
covenant by the Investor to execute any additional documents and instruments
that may be reasonably required to more effectively transfer to and to vest in
Middle Bay the assets underlying the tendered Partnership Units and a power of
attorney to Middle Bay to permit Enex, as General Partner, to execute on the
Investor's behalf any additional documents necessary to consummate the Exchange,
including any documents on behalf of Investors that may be necessary to withdraw
the assets of the Partnership and contribute those assets to Middle Bay.

VALIDITY OF TENDERS

         All questions concerning the validity, form, eligibility (including
time of receipt) and acceptance of Partnership Units tendered will be determined
by Middle Bay, whose determination will be final and binding. The interpretation
by Middle Bay of the terms and conditions of the Exchange Offer (including the
instructions to the Letter of Transmittal) will also be final and binding.
Middle Bay reserves the right to


                                     - 54 -
<PAGE>   67
waive any irregularities or conditions regarding the manner of tender. Any
irregularities in connection with such tenders must be cured within such time as
Middle Bay determines unless waived by Middle Bay.

         Tenders will be deemed not to have been made until irregularities have
been cured or waived. Any Letter of Transmittal not properly completed and
executed will be returned by the Exchange Agent to the tendering Investor as
soon as practicable, unless the irregularities are cured or waived. The Exchange
Agent is under no duty to give notification of defects in tenders and will not
incur liability for failure to give such notification. Delivery of the
Transmittal Letter is at the risk of the Investor. A tender will be effective
only when the properly completed and executed Letter of Transmittal is actually
received by the Exchange Agent. To ensure receipt of the Letter of Transmittal
and all other required documents, if any, when sent by the U.S. mail, Investors
should use certified or registered mail, return receipt requested.

PAYMENTS OF FEES AND EXPENSES

         Fees and expenses incurred in connection with the Exchange Offer will
be paid by Middle Bay, whether or not the Proposal is accepted. Fees and
expenses incident to the Exchange Offer are estimated to be approximately
$343,644, all of which will be funded from Middle Bay's working capital. The
estimated fees and expenses for the Exchange Offer are itemized below:

COMPLIANCE WITH TENDER OFFER PRACTICES

         In conducting the Exchange Offer, Middle Bay will comply with the
provisions of Rule 14e-1 under the Exchange Act relating to the solicitation of
tenders and the payment of consideration in a tender offer.


                        MATERIAL FEDERAL TAX CONSEQUENCES

         The following tax discussion summarizes the federal income tax
consequences of the Exchange. This summary is the opinion of Thrasher, Whitley,
Hampton & Morgan, counsel to Middle Bay in connection


                                     - 55 -
<PAGE>   68
with the Exchange, whose formal opinion (the "Tax Opinion") is included as an
Exhibit to the Registration Statement of which this Prospectus is a part. The
following is intended to provide only a general summary and does not include a
complete analysis of the consequences that may vary with or are contingent upon
individual circumstances, such as a taxpayer who is subject to special
provisions of the Internal Revenue Code. This discussion and opinion does not
address the federal income tax treatment of other transactions related to the
Exchange, any aspect of state, local or foreign tax laws or any federal laws
other than those pertaining to income tax.

         None of the parties have requested a ruling from the Internal Revenue
Service with respect to the federal income tax consequences of the Exchange. No
assurance can be given that future legislation, regulations, administrative
pronouncements or court decisions will not significantly change the law and
materially affect the conclusions expressed herein. Any such change, even though
made after the consummation of the Exchange, could be applied retroactively.

         Unitholders may obtain a copy of the Tax Opinion by sending a written
request to Middle Bay Oil Company, Inc., 1221 Lamar Street, Suite 1020, Houston,
Texas 77010, attention: Frank C. Turner, II.

TAX CONSEQUENCES OF THE EXCHANGE

         Upon the exchange of Partnership Units for Series C Preferred,
Investors must recognize gain or loss equal to the difference between the fair
market value of the Series C Preferred received by them and bases in the
Partnership Units exchanged therefor.

         The Internal Revenue Service might argue that the transaction
constitutes a transfer of assets of the Partnership to Middle Bay for Series C
Preferred, with the Series C Preferred then distributed to Investors not
participating in the Exchange in liquidation of their interests in the
Partnership. Under such a characterization of the transaction, the Partnership
would recognize gain or loss on the disposition of the assets which would be
allocated to those Investors. Such characterization could affect the amount of
gain or loss recognized by them. However, courts evaluating the transfer of all
of the assets of a partnership, followed by a termination of the business of the
partnership, have held, according to a rule known as the "sale of a going
business doctrine," that such transactions will be characterized as a transfer
of partnership interests in exchange for the assets received rather than a
transfer by the partnership of assets and subsequent liquidation. According to
that doctrine, the treatment afforded Unitholders not participating in the
Exchange should not differ from the tax treatment realized by Investors who
agree to exchange their Partnership Units for Series C Preferred. The sale of a
going business doctrine has been implicitly rejected by the Internal Revenue
Service, however, and the doctrine has not been affirmed by any recent court
decision.

         Assuming the Unitholder has held his Interest as a capital asset for
more than one year and assuming his Interest has not been held for sale in the
ordinary course of the Unitholder's trade or business, any gain or loss realized
upon the transfer of Partnership Units will be taxed as long-term capital gain
or loss, except to the extent that the consideration received is attributable to
his allocable share of inventory items and unrealized receivables (including
depreciation recapture and excess intangible drilling and development costs) of
the Partnership. The portion of any gain attributable to these items will be
taxed to the Unitholder


                                     - 56 -
<PAGE>   69
as ordinary income. In addition, in the event of a recharacterization of the
transaction as a transfer of assets, additional ordinary income could be
recognized by the Partnership which would be allocable to Unitholders.

REALIZATION OF SUSPENDED PASSIVE LOSSES

         Upon disposition of Partnership Units, Unitholders will have completely
disposed of their Interests in the Partnership. Any Unitholder who has any
suspended passive losses resulting from the ownership of Partnership Units will
be allowed to recognize those suspended passive losses upon consummation of the
Exchange, assuming the Partnership Units constitute the Unitholder's entire
interest in an activity for purposes of the passive loss rules.

BASIS IN STOCK

         Upon consummation of the Exchange, the basis of the Series C Preferred
received by Investors will generally be equal to the fair market value of such
securities as of the date of consummation of the Exchange. In the case of a
Unitholder not participating in the Exchange, this assumes that the "sale of a
going business doctrine" (explained above) applies to the transaction;
otherwise, such basis will be determined, in the case of such a Unitholder, by
reference to his adjusted basis in his Partnership Units.

         THE PRECEDING DISCUSSION AND OPINION IS INTENDED ONLY AS A SUMMARY OF
MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE AND DOES NOT PURPORT TO
BE A COMPLETE ANALYSIS OR DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT
THERETO. THUS, INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE EXCHANGE, INCLUDING TAX RETURN
REPORTING REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL
AND OTHER APPLICABLE TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX
LAWS.

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with Middle
Bay's Financial Statements and Notes thereto set forth herein.

RESULTS OF OPERATIONS -- 1997

         The factors that most significantly affect Middle Bay's results of
operations are (i) the sales price of crude oil and natural gas, (ii) the level
of production volumes, (iii) the level of lease operating expenses, and (iv) the
level of interest rates. Sales of production and level of borrowing are
significantly impacted by Middle Bay's ability to maintain or increase its
production from existing oil and gas properties or through its exploration and
development activities. Sales prices received by Middle Bay for oil and gas have
fluctuated significantly from period to period. The fluctuations in oil prices
during these periods reflect market uncertainty regarding the inability of OPEC
to control the production of its member countries, production from Iraq, as well
as concerns related to the global supply and demand for crude oil. Gas prices
received by Middle Bay fluctuate generally with changes in the spot market price
for gas. Relatively modest changes in either oil or gas prices significantly
impact Middle Bay's results of operations and cash flow and could significantly
impact Middle Bay's borrowing capacity.

         The table below details the changes in oil and gas revenues, excluding
plant and other revenues, caused by price and volume changes for the years
ending December 31, 1997, 1996 and 1995.

FISCAL 1997

         Total revenues for the twelve months ended December 31, 1997, of
$11,433,000, were $6,546,000 higher than the same period in 1996. The increase
in total revenues was due primarily to higher oil and gas revenues of
$4,827,000, consisting primarily of a $2,464,000 increase in oil revenues and a
$2,363,000 increase in gas revenues. Also contributing to the revenue increase
was $920,000 in revenue from gas processing at the gas plant located at the
Spivey Field and $975,000 in lease bonus and delay rental income on the fee
mineral acreage in Louisiana. The gas processing plant was acquired in the
February 28, 1997


                                     - 60 -

Bison Merger. The increase in oil and gas revenues from 1996 to 1997 was
primarily the result of increases in production which resulted from the Bison
and Shore Mergers. Production from the Bison and Shore Mergers is included from
March 1 and July 1, 1997, respectively. Production of oil and gas for the twelve
months ended December 31, 1997, increased 133% and 96%, respectively, over the
comparable period. During the twelve-month period ended December 31, 1997,
Middle Bay sold 254,000 barrels of oil and 1,929,000 Mcf of gas, as compared to
109,000 barrels of oil and 983,000 Mcf of gas for the comparable period. Oil
production for 1997 was 145,000 barrels higher due primarily to a 58,000 barrel
increase from the Bison Merger and a 76,000 barrel increase from the Shore
Merger. Gas production in 1997 was 946,000 Mcf higher due primarily to a 521,000
Mcf increase from the Bison Merger, a 335,000 Mcf increase from the Shore Merger
and a 188,000 Mcf increase from the Riceville Acquisition. The average price
received on the gas sold in 1997 of $2.39 per Mcf was slightly higher than the
average $2.28 per Mcf received in the comparable period. Oil prices in 1997 of
$18.38 per barrel were 9% lower than the average of $20.26 per barrel received
in the comparable period.

         Middle Bay received approximately $975,000 in lease bonus and delay
rental income on the fee mineral acreage acquired in the Shore Merger over the
six-month period ending December 31, 1997.

         The increase in total revenues of $6,546,000 was less than the increase
in total expenses, before income taxes, of $29,851,000. The principal reasons
for the increase in the overall level of expenses are (1) increased oil and gas
property impairment charge of $20,870,000; (2) increased lease operating and
depletion expenses of $5,715,000 from properties acquired in the Bison and Shore
Mergers which are included with Middle Bay's expenses from March 1 and July 1,
respectively; and (3) increased G&A expenses of $1,699,000 due to increased
number of employees from the Bison and Shore Mergers and higher overall
administrative expenses due to the increased level of activity.

         In the fourth quarter of 1997, Middle Bay charged to impairment expense
$21,148,000 versus $278,000 in the comparable period. The impairment expense was
computed applying the guidelines of FAS #121 "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of." This statement
requires that long-lived assets be reviewed for impairment when events or
changes in circumstances indicate that the carrying value of such assets may not
be recoverable. This review consists of a comparison of the carrying value of
the asset with the asset's expected future undiscounted cash flows without
interest costs. Expected undiscounted future cash flow is defined as "the future
cash inflows expected to be generated by an asset less the future cash outflows
expected to be necessary to obtain those inflows (undiscounted and without
interest charges)." The independent oil and gas engineers identified under
"Experts" determine the expected future undiscounted cash flows. To determine
the expected future undiscounted cash flows of each property, the engineers
estimated each property's oil and gas reserves, relied on certain information
supplied by Middle Bay regarding the oil and gas reserves, applied certain
assumptions regarding price and cost escalations, and applied certain discount
factors for risk, location, type of ownership interest, category of reserves,
operational characteristics and other factors. Estimates of expected future
undiscounted cash flows are to represent management's best estimate based on
reasonable and supportable assumptions and projections. If the expected future
undiscounted cash flows exceed the carrying value of the asset, no impairment is
recognized. If the carrying value of the asset exceeds the expected future
undiscounted cash flows, impairment exists and is measured by the excess of the
carrying


                                     - 61 -
<PAGE>   74
value over the estimated fair value of the asset. Fair value is defined in the
statement as the "amount at which the asset could be bought or sold in a current
transaction between willing parties."

         The impairment expense in the current period of $21,148,000 was
primarily attributable to impairments on three fields--the Esther Field, Spivey
Field and Wellman Field--amounting to $8,394,000, $6,127,000 and $2,257,000,
respectively. The Esther and Wellman Fields were acquired in the Shore Merger,
and the Spivey Field was acquired in the Bison Merger. The impairment on the
Esther Field in Vermilion Parish, Louisiana was due primarily to a change in the
category of reserves from Proved Undeveloped to Probable Undeveloped and changes
in the economics of the development of the reserves. The category of the
reserves was changed due to an abandoned sidetrack attempt in February, 1998 by
the operator on the Proved Undeveloped Reserves. The impairment on the Spivey
Field was due primarily to a decrease in the level of oil prices and changes in
the economics of the Proved Undeveloped Reserves due to information obtained
from the wells drilled in 1997. The impairment on the Wellman Field in Terry
County, Texas was due primarily to decreases in oil prices. Since July 1, 1997,
the posted price of WTI crude oil has fallen from approximately $18.00 per
barrel to $15.00 per barrel at December 31, 1997 or 17%. The total oil
equivalent reserves of the Wellman Field are 95% oil. The remaining impairment
expense of approximately $4,370,000 is attributable to several fields. The
principal reasons for the impairment on these fields are the decrease in oil
prices and the decrease or cessation of oil and gas production.

         Lease operating expenses of $3,849,000 increased by $2,333,000. The
increase was due primarily to the Bison and Shore Mergers which increased lease
operating expenses $1,067,000 and $915,000, respectively. Depletion expense of
$4,567,000 increased by $3,382,000. Depletion increased primarily due to the
Bison and Shore Mergers which increased depletion by $1,279,000 and $1,270,000,
respectively. Interest expense of $671,000 increased by $166,000 due to a higher
loan balance. Dry-hole expense of $1,119,000 increased by $690,000 due primarily
to abandonment costs on three unsuccessful Exploratory Wells drilled in
Louisiana--the Shore Oil Company #1, the Sabine #1 and the Middle Bay Oil
Company #1--with dry-hole costs of $311,000, $177,000 and $168,000,
respectively. General and administrative expense of $2,361,000 increased by
$1,699,000, due primarily to higher salary expense of $724,000, higher
professional fees of $347,000, higher office expenses of $128,000, and higher
IRA/SEP/Other Bonus expenses of $123,000. The remaining increase in general and
administrative expenses was over several expense categories and was due
primarily to an increase in the overall level of activity at Middle Bay as a
result of the Bison and Shore Mergers. The increase in salary expense is due to
increases in salaries of existing employees and salaries associated with
employees added in the Bison and Shore Mergers. At the time of the Bison Merger,
seven employees occupied the Wichita, Kansas office. Effective August 1, 1997,
only four employees will be occupying the Wichita, Kansas office--the President
of Bison, an engineer, geologist and secretary. The President of Shore, an
engineer and a secretary were added in the Shore Merger. In addition, Middle Bay
hired a land manager in July to manage Middle Bay's land and mineral records and
an accounting supervisor in October to assist with the increased accounting
workload. Stock compensation expense of $202,000 increased by $202,000 due to
the vesting of 50% of the restricted stock granted to certain Company employees
in February, 1997. The remaining 50% will fully vest on June 30, 1998. Other
expenses of $317,000 increased $285,000 over the comparable period. The primary
reason for the increase was expenses associated with the Bison and Shore
Mergers.


                                     - 62 -
<PAGE>   75
         Middle Bay reported an operating loss of $23,024,000 for the year ended
December 31, 1997, as compared to an operating profit of $280,000 in the
comparable period.

         Middle Bay reported a deferred tax benefit of $7,451,249 for the year
ended 1997 versus a deferred tax expense of $70,000 in the comparable period.
The primary reason for the deferred tax benefit in 1997 was the oil and gas
reserve impairment on the properties acquired in the Bison and Shore Mergers in
1997 and the NPC Merger in 1996. These three mergers were tax-free mergers, and
the tax basis of the oil and gas properties acquired were carried over on Middle
Bay's books at the merger dates. For accounting purposes, the three mergers were
purchases and the oil and gas properties were recorded on Middle Bay's books at
fair market value on the merger dates. The fair market value was much higher
than the carryover tax basis and a deferred tax liability at the prevailing tax
rate was recorded for the difference. The total deferred tax liability that was
recorded on Middle Bay's books for the Bison, Shore and NPC Mergers was
approximately $12 million. When the impairment reduced the carrying amount of
the oil and gas properties for accounting purposes but not for tax purposes, the
difference between the accounting and tax basis of the properties was reduced
and the deferred tax liability was reduced accordingly, resulting in a deferred
tax benefit.

         Middle Bay reported a net loss of $15,579,340 versus net income of
$205,500 for the comparable period. Middle Bay paid preferred dividends of
$605,000 in the current period and reported a net loss to common stockholders of
$16,184,052 versus net income available to common stockholders of $205,000 for
the comparable period. No preferred dividends were paid in 1996.

FISCAL 1996

         Total revenues for the twelve months ended December 31, 1996, of
$4,886,000, were $1,348,000 higher than the comparable period. The increase in
total revenues was due primarily to higher oil and gas revenues of $1,236,000,
consisting primarily of a $469,000 increase in oil revenues and a $858,000
increase in gas revenues. Total revenues also increased due to higher other
income of $199,000, due primarily to a gas contract settlement of $263,000. The
increase in oil and gas revenues from 1996 to 1995 was primarily the result of
higher oil and gas prices. Production of oil and gas for the twelve months ended
December 31, 1996, increased 1% and 7%, respectively, over the comparable
period. During the twelve-month period ended December 31, 1996, Middle Bay sold
109,000 barrels of oil and 983,000 Mcf of gas, as compared to 107,000 barrels of
oil and 917,000 Mcf of gas for the comparable period. Oil production for 1996
was 1,600 barrels higher due to a 4,300 barrel increase from the successful
wells in the Brigham Agreement, a 500 barrel increase in existing properties,
and a decrease of 3,200 barrels from properties sold in 1996. Gas production in
1996 was 66,000 Mcf higher due to a 25,000 Mcf increase from the successful
wells in the Brigham Agreement and a 78,000 Mcf increase in existing properties
offset by a decrease of 37,000 Mcf from properties sold in 1996. The price
received on the gas sold in 1996 of $2.28 per Mcf was higher than the $1.52 per
Mcf received in the comparable period. Oil prices in 1996 of $20.26 per barrel
were 25% higher than the $16.17 per barrel received in the comparable period.


                                     - 63 -
<PAGE>   76
         The increase in total revenues of $1,348,000 was more than the increase
in total expenses of $646,000. Increases in dry-hole costs and depreciation and
depletion expense accounted for approximately 91% of the total expense increase.

         Lease operating expenses of $1,516,000 increased by $79,000 as a result
of higher expenses on existing properties of $138,000 and expenses on successful
wells in the Brigham Agreement of $4,300 offset by reductions due to properties
sold in 1996 of $63,000. Interest expense of $505,000 decreased by $15,000 due
to lower interest rates and payments on principal in 1996. Dry-hole expense
increased by $346,000 due primarily to abandonment costs of $421,000 associated
with the unsuccessful wells drilled in the Brigham Agreement. Depletion expense
of $1,397,000 increased by $256,000. Regular depletion of $1,119,000 increased
by $134,000 due primarily to higher depletion on existing properties. Write-offs
of proven properties in accordance with SFAS #121 of $277,000 increased by
$121,000. Of the total writedown, 75% is from three single well fields in
Louisiana. One of the fields was the Lake Decade Field which was a major
property in 1995. It contributed $91,000 to cash flow in 1996 before it ceased
producing in December 1996, resulting in an impairment expense of $59,000. The
other two fields, which produced very little in 1996, were minor properties
contributing less than $20,000 to cash flow in 1995, and producing impairment
losses of $95,000 and $55,000. The remaining impairment expense resulted from
several properties, none of which were significant properties in terms of
discounted present value and were primarily mature, small properties that did
not contribute significantly to Middle Bay's cash flow in 1996 and 1995.
Depreciation expense of $60,000 decreased $15,000 due to lower depreciation on
lease and well equipment and corporate office furniture and fixtures which are
depreciated on an accelerated method which declines over the useful life of the
asset. General and administrative expenses decreased by $3,900, due primarily to
Middle Bay's lower 1996 SEP/IRA and 1% NPI contributions of $12,000 compared to
the $60,000 in contributions in 1995, lower accounting expenses of $14,000 and
lower miscellaneous expenses of $18,000 which were partially offset by higher
travel and entertainment expenses of $47,000 and higher legal expenses of
$12,000.

         Middle Bay reported an operating profit of $280,000 for the year ended
December 31, 1996 as compared to an operating loss of $421,000 in 1995. If the
1996 nonrecurring credits of $303,000, consisting of the gas contract settlement
of $263,000 and lease operating expense credit of $40,000, were offset against
the 1995 nonrecurring expenses of $62,000, the change in operating profit would
have decreased to $336,000.

         Middle Bay reported net income of $205,000 for the year ended December
31, 1996, versus a net loss of $331,000 for the comparable period.

NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1998

         For the current period, the revenues and expenses attributable to the
Enex Acquisition are included for the period April through September and those
attributable to the Service Acquisition are included for the months of May
through September. For the comparable period, the revenues and expenses
attributable to the Bison Merger are included for the period March through
September and the Shore Merger are included for the period July through
September.


                                     - 64 -
<PAGE>   77
         Total revenues for the current period of $13,260,000 were $5,358,000
higher than the comparable period. The increase in total revenues was due
principally to increases in oil and gas revenues of $4,165,000 and gain on sale
of properties of $1,523,000. During the current period lease bonus and rental
income on the mineral acreage acquired in the Shore Merger decreased $673,000.
Other revenues in the current period increased $343,000. The increase in the
gain was due to the non-strategic property sales that occurred during
the current period. No gain or loss was recorded on the Enex and Service
Acquisitions properties that were sold in the current period, the proceeds were
credited against the original acquisition cost.

         The increase in oil and gas revenues consisted primarily of a
$1,547,000 increase in oil revenues, a $2,511,000 increase in gas revenues and a
$107,000 increase in other revenues. The increase in oil and gas revenues was
the result of higher oil and gas production. Production of oil increased 128%
and production of gas increased 102%, over the comparable period. The oil
production increase of 239,000 barrels and the gas production increase of
1,370,000 Mcf, were due primarily to the Bison and Shore Mergers and the
Riceville Acquisition which closed in 1997 and the Enex and Service Acquisitions
which closed in 1998. During the current period, Middle Bay sold 428,000 barrels
of oil and 2,713,000 Mcf of gas, as compared to 188,000 barrels and 1,343,000
Mcf for the comparable period. The average price received on the gas sold in the
current period of $2.04 per Mcf was 10% lower than the $2.26 per Mcf received in
the comparable period. The average price received on the oil sold in 1998 of
$11.91 per barrel was 37% lower than the $18.87 per barrel received in the
comparable period. A reclassification of 21,000 barrels and $308,000 in oil
revenues was made in the prior period. The revenues were previously recorded in
gas plant revenues with no volumes associated with the revenues.

         During the current quarter, the Baker #1 well in the Riceville Field, a
major property of Middle Bay, was shut in. The well was sidetracked and began
flowing on or about October 28. The well was selling approximately 500 barrels
of oil and 27,000 Mcf of gas per month, net to Middle Bay, before it was shut
in.

         Total expenses increased $9,161,000 over the comparable period. Due to
the growth of Middle Bay, all categories of expenses increased, except dryhole
and stock compensation expenses.

         Lease operating expenses increased $3,078,000. The increase was due
principally to the additional expenses on the properties acquired in the Bison
and Shore Mergers which closed in 1997 and the Enex and Service Acquisitions
which closed in 1998.

         Geological and geophysical expenses ("G&G expenses") increased
$796,000. In the current period, Middle Bay spent approximately $781,000 on the
Hawkins Ranch Prospect and $132,000 on the Sherburne Prospect versus
approximately $131,000 in the comparable period.

         Depletion, depreciation and amortization expense increased $2,363,000.
Depletion was higher due to depletion on properties acquired in the Bison and
Shore Mergers and the Riceville Acquisition, which closed in 1997, and the Enex
and Service Acquisitions, which closed in 1998.

         Impairment expense increased $492,000. The impairment expense in the
current period was due to an unsuccessful recompletion attempt in the current
quarter on the Goldberg #2 well in the Abbeville Field


                                     - 65 -
<PAGE>   78
located in Vermillion Parish, Louisiana. The reserves had been classified as
proved behind pipe. There was no impairment expense in the comparable period.

         During the current period, dryhole expenses decreased by $115,000. In
the current period the dryhole expense of $331,000 consisted principally of
$199,000 for the dryhole on the South Highbaugh Prospect and additional dryhole
expenses of $102,000 on two dryholes on the Reflection Ridge Prospect. Dryhole
expenses in the comparable period consisted principally of costs through the
Brigham Agreement.

         Interest expense increased $951,000, due primarily to a higher loan
balance.

         Stock compensation expense decreased $34,000 due to the vesting period
for the restricted stock granted to certain Middle Bay employees ending in the
quarter ended June 30, 1998.

         General and administrative expenses ("G&A") increased $1,631,000. The
increase in G&A consists primarily of increases in salaries, performance bonuses
for the previous year, engineering, accounting and legal expenses, rent expense
and office expense. The increase in salary expense was due to increases in
salaries of existing employees, salaries of new employees, salaries associated
with employees added in the Bison and Shore Mergers and salaries associated with
the Enex employees. For the current period, Middle Bay had twenty-three
full-time executive and clerical employees and five Enex employees. Eight
employees were added through the Bison and Shore Mergers and Middle Bay hired
eight employees and one resigned. The increase in rent is due to Middle Bay
previously owning its office in Mobile, Alabama versus renting office space
since Middle Bay's move to Houston in November, 1997. The increases in other G&A
expenses are due to the increase in the general activity of Middle Bay's
business.

         Middle Bay reported an operating loss before minority interest of
$3,738,000 for current period versus operating income of $70,000 for the
comparable period. Due to the Enex Acquisition, Middle Bay records a minority
interest on its income statement to remove the net income or loss attributable
to the minority interest holders of Enex. In the current period, the minority
interest increased the operating loss by $5,000.

         Middle Bay reported a deferred income tax benefit of $1,271,000 in the
current period. No deferred taxes were recorded in the comparable period.

         Middle Bay reported a net loss of $2,467,000 for the current period
versus net income of $70,000 for the comparable period. After considering the
preferred stock dividend requirement of $68,000 in the current period versus
$409,000 in the comparable period, Middle Bay reported a net loss available to
common stockholders in the current and comparable periods of $2,535,000 and
$338,000, respectively.

EFFECTS OF OIL AND GAS PRICE FLUCTUATIONS

         Fluctuations in the price of crude oil and natural gas significantly
affect Middle Bay's operations and the value of its assets. As a result of the
instability and volatility of crude oil and natural gas prices, financial


                                     - 66 -
<PAGE>   79
institutions have become more selective in the energy lending area and have
reduced the percentage of existing reserves that may qualify for the borrowing
base to support energy loans.

         Middle Bay's principal source of cash flow is the production and sale
of its crude oil and natural gas reserves which are depleting assets. Cash flow
from oil and gas production sales depends upon the quantity of production and
the price obtained for that production. An increase in prices permits Middle Bay
to finance its operations to a greater extent with internally-generated funds,
allow Middle Bay to obtain equity financing more easily and lessens the
difficulty of attracting financing alternatives available to Middle Bay from
industry partners and nonindustry investors. However, price increases heighten
the competition for Leases and Prospects, increase the costs of exploration and
development activities and increase the risks associated with the purchase of
Producing Properties.

         A decline in oil and gas prices (i) reduces the cash flow internally
generated by Middle Bay, which in turn reduces the funds available for servicing
debt and exploring for and replacing oil and gas reserves, (ii) increases the
difficulty of obtaining equity financing, (iii) reduces the number of Leases and
Prospects available to Middle Bay on reasonable economic terms and (iv)
increases the difficulty of attracting financing alternatives available to
Middle Bay from industry partners and nonindustry investors. However, price
declines reduce the competition for Leases and Prospects and correspondingly
reduce the prices paid for Leases and Prospects. Furthermore, exploration and
production costs generally decline, although the decline may not be at the same
rate of decline of oil and gas prices.

         Since September, 1997, the price of oil has declined dramatically. The
posted price of WTI crude oil has declined from a high of approximately $20.00
per barrel in October, 1997 to lows in June, 1998 of approximately $9.00 per
barrel. As of September 30, 1998, the posted price of WTI was approximately
$13.50. The average posted price of WTI crude oil for the year 1997 was
approximately $18 per barrel. As of September 30, 1998, approximately 42% of
Middle Bay's proved developed producing oil and gas reserves, on a BOE basis,
are oil. If oil prices remain at or near the September, 1998 levels, Middle
Bay's revenue and cash flow will decrease relative to the year ended 1997. Gas
prices peaked in November, 1997 at approximately $3.80 Mcf, but have declined to
levels approximating $2.25 Mcf as of September 30, 1998.

SEASONALITY

         The results of operations of Middle Bay are somewhat seasonal due to
seasonal fluctuations in the price for natural gas. Generally, natural gas
prices are higher in the first and fourth quarter of the year due to colder
winter weather and resulting higher demand for natural gas during these months.
Due to these seasonal fluctuations, results of operations for individual
quarterly periods may not be indicative of results on an annual basis.

INFLATION AND CHANGING PRICES

         Inflation principally affects the costs required to drill, complete and
operate oil and gas wells. In recent years, inflation has had a minimal effect
on the operations of Middle Bay. Costs have generally declined over the near
future due to the decrease in drilling activity in the United States. Unless
increasing


                                     - 67 -

oil and gas prices spur large increases in industry activities, management
believes costs will remain relatively stable over the next year.

CAPITAL RESOURCES AND LIQUIDITY -- FISCAL 1997 AND FISCAL 1996

         Cash flow from operations before working capital changes of $2,925,000
increased $1,225,000 over the comparable period. This increase was due to a
$3,184,000 increase in oil and gas cash flow, an increase of $554,000 in other
income offset by increases in general and administrative costs of $1,654,000,
dry-hole costs of $691,000, interest expense of $166,000 and $1,000 in current
income taxes. Increased oil and gas operations cash flow before working capital
changes was principally the result of increases in oil and gas production. The
other income increase was due primarily to lease bonus and delay rental income
on the minerals acquired in the Shore Merger.

         Cash flow from operating activities for the year ending December 31,
1997, of $2,582,000 increased $1,193,000 over the comparable period. Changes in
working capital reduced cash flow by $32,000 over the comparable period.
Differences in the amount and timing of accrual and payment of payables and the
accrual and receipt of revenues account for the changes in working capital.

         Additions to oil and gas properties were higher than the comparable
period due to the Bison and Shore Mergers and increased acquisitions and
drilling in the current period. The increase in the amount of cash used for debt
payments was due primarily to the $2,105,000 refinancing of the term note
assumed in the Shore Merger and the $385,000 of payments and refinancing on the
note assumed in the NPC Merger. No principal payments have been required over
the period April 1, 1996 to December 31, 1997 on Middle Bay's $6 million, $15
million and $50 million convertible loans. The increase in the proceeds from
debt issued was due to the refinancing of the notes assumed in the Shore and NPC
Mergers, $3,000,000 issued in the Riceville Acquisition and the financing of the
leasehold and seismic costs in the amount of $385,000 associated with the
Reflection Ridge Prospect. The increase in proceeds from issuance of preferred
stock was due to the preferred stock issued to finance portions of the Bison and
Shore Mergers.

         Middle Bay's operating activities provided net cash of $2,582,000 for
the year ending December 31, 1997. During this period, net cash from operations
and cash on hand was used principally for exploratory and developmental drilling
of $2,004,000, workovers of $431,000, exploration prospects of $415,000 and
proved property acquisitions of $921,000. Debt proceeds were used to finance
$3,000,000 of proved property acquisition and $285,000 of prospects. Common
stock was issued for $260,000 of proved property acquisitions, excluding
mergers. Of the $2,004,000 spent on exploratory and developmental drilling,
approximately $420,000 was spent in the Brigham Agreement, $880,000 in the
Spivey Field in Kansas, $100,000 in the Wellman Unit in Texas, and the remainder
was spent on several wells in Louisiana, Mississippi and Oklahoma. Of the
$431,000 spent on workovers, approximately $80,000 was spent at Wild Fork Creek
Field in Alabama, $44,000 at the Wright Field in Louisiana, $30,000 at Magnolia
in Arkansas and $25,000 at Lake Trammel Field in Texas. The remaining amount was
spent on several different properties. The $700,000 total amount spent on
prospects consisted primarily of $286,000 on Reflection Ridge in Kansas,
$232,000 on Hawkins Ranch in Texas, $67,000 on the Sherburne Prospect in
Louisiana, $31,000 on the Quarry Prospect in New Mexico and $55,000 on S.
Highbaugh in Texas. Middle Bay spent


                                     - 68 -
<PAGE>   81
$7,140,000 on the Bison Merger. This includes the $1,446,000 in non-oil and gas
assets, which were subsequently sold for the amount paid. Middle Bay spent
$514,000 on the Shore Merger. Amounts spent on debt retirement consisted
principally of the payment in full of the note assumed in the Shore Merger of
$2,105,000, monthly principal payments on the $385,000 term note assumed in the
NPC Merger and the refinancing of the NPC term note of $274,000. The principal
payments on the $6 million convertible loan were suspended when Middle Bay
converted the $5.6 million term note to a $6 million convertible loan on April
3, 1996.

         Middle Bay incurred $1,119,000 in dry hole costs consisting principally
of three wells drilled in Louisiana and one well drilled in Oklahoma. The
Louisiana wells were the Shore Oil Company #1, the Sabine #1 and the Middle Bay
Oil Company #1 with dry-hole costs of $311,000, $177,000 and $168,000,
respectively. The Oklahoma well was the Hannah #1 with a dry hole cost of
$301,000.

         Middle Bay incurred $223,000 in geological and geophysical costs ("G&G
Costs") which consisted primarily of $130,000 in geological and geophysical
costs on the Reflection Ridge Prospect and $62,000 on the Hawkins Ranch
Prospect. The above discussion of capital costs does not include amounts
expensed as dry hole and geological and geophysical costs.

         Middle Bay had current assets of $4,223,000 and current liabilities of
$2,891,000, which resulted in working capital of $1,332,000 at December 31,
1997. This was an increase of $546,000 from working capital of $786,000 at
December 31, 1996. Working capital increased primarily due to increased cash
flow from operations, cash proceeds from stock option exercises, and no monthly
principal payments on the Convertible Loan, offset partially by increased
amounts spent on exploratory and developmental drilling and working capital
changes. The current maturity of long-term debt was higher in 1997 because of
the larger principal balance requiring payment in the following year. In 1997,
the $50 million Convertible Loan requires principal payments beginning April 1,
1998 versus the $6 million Convertible Loan requiring principal payments
beginning October 1, 1997 in the comparable period. Middle Bay's current ratio
of 2.78, calculated under the terms of the Convertible Loan which excludes
stockholder receivables and debt due under the $50 million Convertible Loan, is
in excess of the 0.90 to 1.00 required.

CAPITAL RESOURCES AND LIQUIDITY -- NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1998

         Cash flow from operating activities for the current period of
$2,059,000 decreased $809,000 over the comparable period. The decrease in cash
flow was due primarily to higher G&G, interest and G&A expenses, offset by
increases in cash flow from oil and gas and working capital changes. Cash flow
from oil and gas properties increased $1,087,000 over the comparable period. Oil
and gas prices decreased 37% and 10%, respectively, while oil and gas production
increased 128% and 102%, respectively. The change in working capital increased
cash flow by $1,816,000 over the comparable period. The change in working
capital was caused principally by timing differences in the payment of expenses
and receipt of revenues. The cash flow to debt coverage ratio of 0.66 is less
than the 1.25 required under the $100 million Revolver agreement. Middle Bay has
received a twelve-month default waiver effective September 30, 1998. Middle Bay
made $1,370,000 of required principal payments under the $100 million Revolver
in the current period. During the current period, Middle Bay made principal
payments of $2,145,000 from property sales proceeds.


                                     - 69 -
<PAGE>   82
Middle Bay also made a principal payment of $1,500,000 on the $100 million
Revolver ten days after the close of the Enex tender offer.

         Additions to oil and gas properties were lower than the comparable
period due primarily to the $3.5 million Riceville Acquisition in August, 1997.
The amount spent on acquisitions is higher due to the Enex Acquisition that
closed March 27, 1998 and the Service Acquisition that closed April 16, 1998.
Middle Bay acquired approximately 79% of Enex common stock for cash in a tender
offer that closed March 27, 1998. Middle Bay also acquired substantially all of
the oil and gas assets of Service Drilling for cash and common stock. The
increase in the amount of cash used for debt payments was due to the replacing
of the $50 million Convertible Loan, with a principal balance of $10,956,000
with the $100 million Revolver and principal payments of $5,015,000 on the $100
million Revolver. No monthly principal payments were required over the period
April 1, 1997 to March 31, 1998 on Middle Bay's $6 million, $15 million and $50
million Convertible Loans. The increase in the proceeds from debt issued was due
to proceeds from the $100 million Revolver which were used to replace the $50
million Convertible Loan, to finance the Enex Acquisition and to partially
finance the Service Acquisition. No preferred stock was issued in the current
period versus the $9 million issued under the Preferred Stock Agreement with
Kaiser-Francis in the comparable period. Kaiser-Francis converted all of the
Series A Preferred Stock on January 31, 1998.

         Middle Bay's operating activities provided net cash of $2,059,000 for
the current period. During this period, net cash from operations, cash from
property sales and cash on hand was used principally for acquisitions and
exploratory and developmental drilling. Approximately $149,000 was spent to
acquire a well in the Spivey Field. Approximately $171,000 was spent on
leasehold and legal costs on the Hawkins Ranch Prospect. Approximately
$1,038,000 was spent on exploratory drilling and approximately $1,945,000 was
spent on developmental drilling. The principal exploratory wells in the current
period were the S. Highbaugh Prospect ($199,000), the Galloway Prospect
($148,000) and the Sherburne Prospect ($416,000). The principal developmental
wells drilled in the current period were the Kuehling #1 sidetrack ($529,000) in
the Esther Field, several wells in the Lake Trammel Field ($207,000), a workover
on a well in the Abbeville Field ($245,000), a workover on the Baker well in the
Riceville Field ($104,000) and workovers in the Spivey ($111,000) and Wellman
($124,000) Fields. Additional developmental drilling was done in the Convis,
Custer City and Loco Hills Fields. Middle Bay spent approximately $15,960,000 on
the Enex Acquisition which was financed entirely with debt proceeds from the
$100 million Revolver. Middle Bay spent approximately $6,500,000, excluding
post-closing adjustments, on the cash portion of the Service Acquisition,
$1,000,000 from cash on hand and the remainder with proceeds from the $100
million Revolver. Amounts spent on debt retirement consisted principally of the
replacement of the $50 million convertible loan. Middle Bay paid approximately
$778,000 in cash distributions to the minority interest partners in the Enex
Partnership for the nine-month period ending September 30. Cash spent on
furniture, fixtures and other assets consists principally of costs related to
the ongoing work on the Enex and Enex Partnership mergers, computer equipment
and software.

         Middle Bay had current assets of $6,797,000 and current liabilities of
$6,915,000, which resulted in working capital deficit of $118,000 as of
September 30, 1998. This was a decrease of $1,431,000 from the working capital
of $1,313,000 as of December 31, 1997. Working capital decreased primarily due
to the higher current maturity of long-term debt and higher accounts payable.
The current maturity of long-term


                                     - 70 -
<PAGE>   83
debt increased because the amount of debt outstanding increased in connection
with the Enex and Service Acquisitions. Accounts payable increased because of
the increased number of properties and increased drilling activity. Middle Bay's
current ratio of 1.46, calculated under the terms of the $100 million Revolver
agreement, which excludes and current maturities of debt due under the $100
million Revolver, was in excess of the 0.90 to 1.00 required.

         Abandonment Accruals

         In the current period, Middle Bay estimated abandonment accruals
amounting to approximately $485,000. An abandonment accrual of $450,000 was made
for certain properties located in Florida. These properties were acquired in the
Enex acquisition and are expected to be plugged and abandoned in the third or
fourth quarter of 1998.

         Minor Property Sale

         On August 13, 1998, the Oil and Gas Asset Clearinghouse auctioned
several hundred oil and gas properties owned by Middle Bay. The auctioned
properties included properties acquired in the Enex and Service Acquisitions.
Certain non-strategic properties were subject to minimum bid. The majority of
the properties were sold by auction with no minimum bids. Middle Bay received
net proceeds of $2,635,000 from the sale of properties at the auction.

         During the current period, Middle Bay also sold certain other
non-strategic oil and gas properties in private sales for gross proceeds of
$1,860,000.

         Under the terms of the $100 million Revolver, when mortgaged properties
are sold, the borrowing base shall be reduced and, if necessary, proceeds from
the sales of properties shall be applied to the debt outstanding in an amount
equal to the loan value attributable to such properties sold. Of the total
proceeds received from property sales, $2,145,000 was used to repay principal on
the $100 million Revolver.

         $100 Million Line of Credit

         In conjunction with the Enex acquisition on March 27, 1998, Middle Bay
entered into a new debt agreement with the banks. The new debt agreement is a
$100 million reducing, revolving line of credit (the "$100 million Revolver")
with current borrowings under a term note maturing April 1, 2001. The entire
principal balance of the Company's $50 million Convertible Loan at the Bank of
Oklahoma was replaced with the $100 million Revolver. The Bank of Oklahoma is a
participating lender with Compass Bank.

         The $100 million Revolver provided for an initial borrowing base of $29
million. The initial borrowing base was reduced to $27.5 million within ten days
after the effective date and further reduced by $275,000 per month beginning May
1, 1998 and ending October 1, 1998. In conjunction with the Service acquisition,
the borrowing base was increased to $32,600,000 and the monthly borrowing base
reductions were increased to $330,000. The borrowing base and the scheduled
reduction amount shall be redetermined semi-annually by unanimous consent of the
lenders beginning October 1, 1998. The principal is due at


                                     - 71 -
<PAGE>   84
maturity, April 1, 2001. Monthly principal payments are made as required in
order that the outstanding principal balance does not exceed the borrowing base.
Interest is payable monthly and is calculated at the prime rate. Middle Bay may
elect to calculate interest under the Libor rate, as defined in the agreement.
The Libor rate increases by (a) 2.00% if the outstanding loan balance and
letters of credit are equal to or greater than 75% of the borrowing base, (b)
1.75% if the outstanding loan balance and letters of credit are less than 75% or
greater than 50% of the borrowing base, or (c) 1.50% if the outstanding loan
balance and letters of credit are equal to or less than 50% of the borrowing
base. Libor interest is payable at maturity of the Libor loan, which cannot be
less than thirty days.

         At September 30, 1998, Middle Bay had $27,455,000 outstanding under the
$100 million Revolver and approximately $1,350,000 of outstanding letters of
credit. As of September 30, 1998, Middle Bay is paying Libor plus 2.00% on a
sixty-day Libor loan for $25,470,000 and prime on $1,985,000.

         Middle Bay paid a facility fee equal to 3/8% of the initial borrowing
base and is required to pay 3/8% on any future increase in the borrowing base
within five days of written notice. Middle Bay is required to pay a quarterly
commitment fee on the unused portion of the borrowing base of one-half percent
if the outstanding loan balance plus letters of credit are greater than 50% of
the borrowing base or three-eighths percent if the outstanding loan balance plus
letters of credit are less than or equal to 50% of the borrowing base. The
Company is required to pay a letter of credit fee on the date of issuance or
renewal of each letter of credit equal to the greater of $500 or one and
one-half percent of the face amount of the letter of credit.

         Middle Bay has granted to the banks liens on substantially all of the
Company's oil and natural gas properties, whether currently owned or hereafter
acquired, and a negative pledge on all other oil and gas properties. The $100
million Revolver requires, among other things, a cash flow coverage ratio of
1.25 to 1.00 and a current ratio of 0.9 to 1.00 determined on a quarterly basis.
The $100 million Revolver prohibits the payment of any cash dividend or
distribution or the purchase of any class of its capital stock.

         Series B Preferred Stock

         In connection with the Shore Merger, effective September 30, 1997,
Middle Bay issued 266,667 shares of Series B Preferred Stock ("Series B"). The
Series B is nonvoting and pays no dividends. The Series B has a liquidation
value of $7.50 per share and was junior to the Series A Preferred. For a period
of sixty-three months subsequent to September 30, 1997, any holder of the Series
B may convert all or any portion of Series B shares into Middle Bay common stock
("Common") at a ratio of one share of Common for each Series B share, or at any
time on or after January 1, 1998, the holders may convert a portion of their
Series B shares based on a conversion method whereby a number of convertible
Series B shares are exchanged using the Alternative Conversion Factor, which is
calculated as the increase in value of approximately 40,000 net mineral acres in
South Louisiana owned by Middle Bay at the end of the year divided by $8
million.

         The Alternative Conversion Factor is then multiplied by 1,066,000 to
arrive at the potential converted number of common shares received. Upon
expiration of the conversion period, unless the Company has given notice to
redeem the Series B, all of the shares of Series B shall be automatically


                                     - 72 -
<PAGE>   85
converted. In no event shall the aggregate total number of shares of Common into
which the Series B are converted be less than 266,667 shares or exceed 1,333,333
shares, unless further increased for any anti-dilution provisions.

         As of September 30, 1998, no additional shares of Series B have been
issued.

         Stock Purchase Agreement

         On September 4, 1996, the Company signed a stock purchase agreement
with Kaiser Francis Oil Company ("the Agreement"). The Agreement provides for
the purchase of 1,666,667 shares of Series A Preferred Stock ("Series A") at
$6.00 per share over a five-year period beginning September 4, 1996 with minimum
incremental investments of $500,000 each. Each issuance of Series A is subject
to approval by Kaiser-Francis of the use of proceeds. The Series A is nonvoting
and accrues dividends at 8% per annum, payable quarterly in cash. The Series A
is convertible at any time after issuance into shares of common stock at the
rate of two shares of common stock for each share of preferred before January 1,
1998. At December 31, 1997, all of the Series A had been issued and on January
31, 1998, all of the Series A was converted.

         The Enex Acquisition

         On March 27, 1998, the Company acquired 1,064,032 shares of the common
stock of Enex, for $15 cash per share pursuant to the Company's tender offer
that began February 19, 1998. The Enex shares acquired by the Company represent
79.2% of the total outstanding Enex common stock. The Company applied the
purchase method of accounting to the Enex acquisition. The purchase price of
$15,960,480 was financed with proceeds from the Company's $100 million Revolver.
The Company also incurred approximately $60,934 in legal, accounting and
printing expenses and issued 33,825 shares of Company common stock for finders
fees to unrelated third parties.

         As part of the Enex acquisition, the Company entered into an agreement,
effective April 15, 1998, with the former president of Enex that provides for
monthly payments of $20,000 until expiration of the agreement on May 18, 2002.
The present value of the agreement, applying a 10% discount rate, is
approximately $788,000 and is included in other liabilities (current and long
term). The monthly payments serve as consideration for consulting, a covenant
not to compete and a preferential right to purchase certain oil and gas
acquisitions which the former president controls or proposes to acquire during
the term of the agreement. The Company will reimburse the former president each
month for reasonable and necessary business expenses incurred in connection with
the performance of consulting services. The agreement survives the former
president and his spouse and is nonassignable.

         Enex, a Delaware corporation, is an independent oil and gas production
and development company headquartered in Kingwood, Texas with operations
primarily in Texas. Enex engages primarily in managing and acquiring producing
oil and gas properties and does not engage in significant drilling activities.
Enex operates over 100 wells in South Texas. Enex shares are traded on the
NASDAQ Stock Market National Market System under the symbol ENEX. Concurrent
with the closing of the Enex acquisition, the Enex


                                     - 73 -
<PAGE>   86
Board of Directors resigned and were replaced by the persons who constitute
Middle Bay's Board of Directors. Enex is presently being operated as a
majority-owned subsidiary of the Company.

         In addition to managing and acquiring direct interests in producing oil
and gas properties, Enex serves as general partner of Enex Consolidated
Partners, L.P. (the "Enex Partnership"). The Enex Partnership is a New Jersey
limited partnership that was formed on June 30, 1997 from the combination of
thirty-four Enex oil and gas limited partnerships. The Enex Partnership, also
headquartered in Kingwood, Texas, is engaged in the oil and gas business through
the ownership of various interests in oil and gas properties. Approximately 73%
of Enex's estimated future net revenues from proved reserves at December 31,
1997 is attributable to its interests in the Enex Partnership and approximately
27% is attributable to the properties owned directly by the Company, after
deducting the minority interest share of the Enex Partnership. As general
partner, Enex has a 4.1% interest in the net revenues and gains generated by
properties owned by the Enex Partnership. In addition to the general partner
interest, Enex owns a 56.2% limited partner interest in the Enex Partnership.

         The Enex Partnership makes periodic cash distributions to the limited
partners. The distributions for the nine months ended September 30, 1998 and the
years ended 1997 and 1996 were approximately $3.6 million, $4.5 million and $2.4
million, respectively. Considering its general and limited partner interest,
Enex's total interest in the Enex Partnership is approximately 57.99%. Based on
Middle Bay's 79.2% ownership of Enex, the Company has an effective ownership of
the Enex Partnership of 45.9%

         Because Middle Bay's ownership of Enex is greater than 50%, Middle
Bay's consolidated financial statements at September 30, 1998 include 100% of
the accounts of Enex and the Enex Partnership. Enex consolidates 100% of the
Enex Partnership on its books for financial reporting purposes because its
ownership in the Enex Partnership is greater than 50%. The minority interest on
the Company's books reflects the equity interest of the minority partners in
Enex (20.8%) and the minority partners in the Enex Partnership (43.8%).

          The operations of Enex and the Enex Partnership for the six months
ended June 30, 1998 were included in the financial statements of Middle Bay.

         Future Capital Requirements

         Middle Bay has made and will continue to make substantial capital
expenditures for acquisition, development and exploration of oil and natural gas
reserves. In fact, because the Company's principal natural gas and oil reserves
are depleted by production, its success is dependent upon the results of its
acquisition, development and exploration activities.

         Middle Bay expects to incur a minimum of approximately $1,000,000 in
capital expenditures over the next twelve months. Middle Bay expects that
available cash, cash flows from operations and cash proceeds from asset sales of
certain noncore properties will be sufficient to fund the planned capital
expenditures through 1998 in addition to funding interest and principal
requirements on the $100 million


                                     - 74 -
<PAGE>   87
Revolver. However, the Company may require additional borrowings under the $100
million Revolver or additional equity funding to raise additional capital to
fund any acquisitions.

         Because future cash flows and the availability of financing are subject
to a number of variables, such as the level of production and prices received
for gas and oil, there can be no assurance that Middle Bay's capital resources
will be sufficient to maintain planned levels of capital expenditures.

         On October 1, 1998, the principal outstanding under the $100 million
Revolver was approximately $27.4 million and the outstanding letters of credit
were approximately $0.6 million. The borrowing base at October 1, 1998 was
calculated at approximately $28.9 million. Under the terms of the $100 million
Revolver, the borrowing base declines $330,000 in October and $250,000 monthly
beginning November 1. Effective January 1, 1999, the borrowing base determined
at October 1, 1998 will be adjusted to $25.4 million if the Company does not
successfully complete the Enex Partnership Merger. Effective January 1, 1999, if
the Company successfully completes the Enex Partnership Merger, the borrowing
base determined at October 1, 1998 will be readjusted to $33.1 million and the
monthly borrowing base reduction will be increased to $290,000. Funds spent on
debt retirement reduce the amount of cash flow available to spend on
acquisition, development and exploration activities.

         By the end of the first quarter of 1999, Middle Bay expects to have the
operations of Enex and the Enex Partnership fully consolidated into its
operations at Middle Bay's headquarters in Houston. It is expected that the
Company will realize certain cost savings in the consolidation of these
operations.

         Current Activities

         As of November 11, 1998, one exploratory well was being drilled and the
Louis Mayard No. 1 well was in final stages of being plugged and abandoned.

         Year 2000 Computer Issues

         The Company has completed its internal reviews of Year 2000 issues and
has identified three areas that, if not adequately addressed, could materially
impact Middle Bay: (1) accounting systems and information technology systems;
(2) computer controlled and other embedded technology; and (3) third-party
compliance.

          The Company has updated its accounting software so that it is Year
2000 compliant or capable of timely conversion to Year 2000 compliance for an
additional nonmaterial cost.

         Middle Bay owns or leases the pumping and other equipment necessary to
service the fields in which serves as operator. Middle Bay is currently
evaluating the extent to which this machinery may contain non-Year 2000
compliant embedded systems. Middle Bay believes that a large scale failure of
such equipment could have a negative material impact on the Company. Middle Bay
is currently in the planning stage regarding Year 2000 issues concerning its
non-operated properties.

         Middle Bay has a material interest in a large number of fields which
are operated by third parties. The simultaneous failure of the operation of a
large number of these third-party fields could have a negative material impact
on the Company. Middle Bay is making individual inquiries as to the state of
each operator's Year 2000 preparation activities. Middle Bay cannot, however,
accurately predict at this time how many, if any, of these third parties will
adequately address their Year 2000 issues. Middle Bay is currently in the
assessment stage regarding Year 2000 issues concerning its operated properties.

         Middle Bay would also likely suffer a material adverse impact if its
banking institutions do not adequately address their Year 2000 issues, if any.
The Company is currently inquiring into any such issues.

         Middle Bay does not currently have a contingency plan in place
sufficient to address all Year 2000 issues related to third-party preparedness.
Middle Bay is currently evaluating the feasibility and effectiveness of such a
plan.

         Middle Bay expects to have all of the material Year 2000 issues, which
includes the financial impact on the Company, assessed by June 30, 1999.

GENERAL

         On September 4, 1996, Middle Bay signed a Preferred Stock Agreement
with Kaiser-Francis. The Preferred Stock Agreement provides for the purchase of
1,666,667 shares of Series A by Kaiser-Francis over a five-year period,
beginning September 4, 1996, with minimum incremental investments of $500,000
each. Each issuance is subject to approval by Kaiser-Francis of the use of
proceeds. The Series A was nonvoting and accrued dividends at 8% per annum,
payable quarterly in cash. At December 31, 1997, 100% of the Series A had been
issued to partially finance the NPC, Bison and Shore Mergers, and in January,
1998, Kaiser-Francis converted 100% of the Series A into 3,333,334 shares of
Middle Bay common stock.

         In connection with the merger with Shore Oil Company effective June 30,
1997, Middle Bay issued 266,667 shares of Series B Preferred Stock ("Series B").
The Series B is nonvoting and pays no dividends. The Series B has a liquidation
value of $7.50 per share and is junior to the Series A Preferred. For a period
of sixty-six months subsequent to June 30, 1997, any holder of the Series B may
convert all or any portion of Series B shares into Middle Bay common stock at a
ratio of one share of common stock for each Series B share, or at any time on or
after January 1, 1998, the holders may convert a portion of their Series B
shares based on a conversion method whereby a number of convertible Series B
shares are exchanged using the Alternative Conversion Factor, which is
calculated as the increase in value of approximately 40,000 net mineral acres in
South Louisiana owned by Middle Bay at the end of the year divided by $8
million.

         The Alternative Conversion Factor is then multiplied by 1,066,000 to
arrive at the potential converted number of common shares received. Upon
expiration of the conversion period, unless Middle Bay has given notice to
redeem the Series B, all of the shares of Series B shall be automatically
converted. In no event shall the aggregate total number of shares of common
stock into which the Series B are converted be less than 266,667 shares or
exceed 1,333,333 shares, unless further increased for any anti-dilution
provisions.

         Middle Bay's liquidity position and current and anticipated cash flows
from operations remain adequate for its general requirements. However, because
future cash flows and the availability of financing are subject to a number of
variables, such as the level of production and prices received for gas and oil,
there can be no assurance that Middle Bay's capital resources will be sufficient
to maintain planned levels of capital expenditures.

CAPITAL EXPENDITURES -- FISCAL 1997 AND FISCAL 1996

         Total capital expenditures, excluding mergers, for oil and gas
properties in fiscal 1997 and 1996 were $7,316,000 and $1,597,000, respectively.
Total capital expenditures for mergers in 1997 and 1996 were $27,586,000 and
$2,618,000, respectively. Total capital expenditures for dry holes and G&G in
1997 and 1996 were $1,341,000 and $429,000, respectively.

         Middle Bay has made and will continue to make substantial capital
expenditures for acquisition, development and exploration of oil and natural gas
reserves. In fact, because Middle Bay's principal natural gas and oil reserves
are depleted by production, its success is dependent upon the results of its
acquisition, development and exploration activities.

         Middle Bay, excluding Enex and Service Drilling, expects to incur a
minimum of approximately $1,400,000 in capital expenditures over the next twelve
months. Middle Bay expects that available cash, cash flows from operations and
cash proceeds from asset sales of certain noncore properties will be sufficient
to fund the planned capital expenditures through 1998, in addition to funding
interest and principal requirements on the $100 million credit facility.
However, Middle Bay may require additional borrowings under the $100 million
credit facility or additional equity funding to raise additional capital to fund
any acquisitions.

         Because future cash flows and the availability of financing are subject
to a number of variable, such as the level of production and prices received for
gas and oil, there can be no assurance the Middle Bay's capital resources will
be sufficient to maintain planned levels of capital expenditures.

         Middle Bay does not anticipate that it will incur any material
expenditures to address Year 2000 issues. Except as disclosed under "Capital
Resources and Liquidity - Year 2000 Issues," above, Year 2000 issues do not
represent a known material event or uncertainty to Middle Bay. To the extent
that Middle Bay may be adversely affected by Year 2000 issues of its suppliers,
customers and other entities, Middle Bay does not believe it will be more
adversely affected than other companies in its industry with similar operations.

RECENTLY-ISSUED ACCOUNTING PRONOUNCEMENTS

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 130, "Reporting Comprehensive Income." This statement establishes
standards for reporting and display of comprehensive income and its components
in the Company's financial statements. Comprehensive income includes all changes
in the Company's equity except investments by and distributions to owners and
includes, among other things, foreign currency translation adjustments. In June
1997, the FASB also issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." This statement


                                     - 77 -
<PAGE>   90
establishes standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments be included in interim reports issued to shareholders. Both of these
statements are effective for financial statements for periods beginning after
December 15, 1997. As both SFAS Nos. 130 and 131 establish standards for
reporting and display, the Company does not expect the adoption of these
statements to have a material impact on its financial condition or results of
operations.

         In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes standards of
accounting for and disclosures of derivative instruments and hedging activities.
This statement is effective for fiscal years beginning after June 15, 1999. As
Middle Bay historically has not entered into derivative instruments for
non-trading (hedging) purposes or for trading purposes, the Company does not
expect this statement to have a material impact on its financial condition or
results of operations upon implementation.


                      SELECTED FINANCIAL DATA - PARTNERSHIP

PARTNERSHIP SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA

         The following selected financial data for the Partnership as of and for
each of the years in the two-year period ended December 31, 1997 are derived
from the Partnership's audited financial statements. The selected consolidated
financial data for the nine months ended September 30, 1997 and 1998 are derived
from the Partnership's unaudited financial statements. In the opinion of
management, such unaudited financial statements contain all adjustments
(consisting of only normal recurring accruals) necessary for a fair presentation
of the financial condition and results of operations as of and for the periods
presented. The balance sheet data for the Partnership as of December 31, 1996 is
not available because the Partnership was not formed until June 30, 1997. All of
the operating data for the Partnership prior to June 30, 1997 is a summation of
the individual partnerships' selected financial data. The following financial
information consists of pro forma data for the years ended December 31, 1997 and
1996 for the combined partnerships assuming the consolidation had taken place at
January 1, 1997 and 1996, respectively. Operating results for the nine months
ended September 30, 1998 are not necessarily indicative of the results that may
be expected for the entire fiscal year ending December 31, 1998. The selected
financial data below should be read in conjunction with the Partnership's
financial statements and related notes thereto and Management's Discussion and
Analysis of Financial Condition and Results of Operations included elsewhere in
this Prospectus.

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

         The following discussion should be read in conjunction with the
Partnership's Financial Statements and Notes thereto set forth herein.

RESULTS OF OPERATIONS

         The Company was formed on June 30, 1997 from the combination of
thirty-four limited partnerships. The Consolidation created a new accounting
basis in the carrying value of property. Oil and gas property was written down
by $1,561,322 from the net carrying value of property in the combined
Predecessor Partnerships. The decremental depletion associated with the net
decrease in property was approximately $123,000 for the last six months of 1997.

         To facilitate comparisons between periods, results of operations are
presented on both an actual basis for the Enex Consolidated Partnership, L.P.
and the Predecessor Partnerships and on a pro forma basis as if the
Consolidation had taken place at the beginning of each period presented. These
results do not reflect the results which would have been obtained if the
Consolidation had actually occurred on the dates indicated or the results that
may be expected in the future.

         The following financial information consists of pro forma data for the
years ended December 31, 1997 and 1996 for the combined partnerships assuming
the consolidation had taken place at January 1, 1997 and 1996, respectively:

         The total combined oil, gas and gas plant sales decreased to
$11,160,836 in 1997 from $12,345,499 in 1996. This represents a decrease of
$1,184,663 or 10%. Oil sales decreased by $1,419,810 or 20%. A 12% decrease in
oil production due to natural production declines caused sales to decrease by
$877,908. A 9% decrease in the average oil sales price decreased oil sales by an
additional $541,902. Gas sales increased by $147,655 or 3%. A 10% increase in
the average gas sales price increased revenues by $388,395. This was offset by a
5% decrease in gas production. Sales of natural gas liquids and gas plant gas
increased by $87,492 or 10%. A 15% increase in the average gas plant products
sales price increased sales by $130,370. This increase was partially offset by a
5% decrease in production of gas plant products. The decreases in oil, natural
gas and gas plant products production were primarily a result of natural
production declines. The decrease in oil sales price corresponds with changes in
the overall market for the sale of oil. The increases in the gas and gas plant
products average sales price correspond with changes in the overall market for
these products.

         The total combined lease operating expenses decreased to $3,589,836 in
1997 from $3,616,133 in 1996. The decrease of $26,297 or 1% was primarily due to
the changes in production, noted above.

         The total combined depreciation and depletion expense decreased to
$1,839,877 in 1997 from $2,145,385 in 1996. This represents a decrease of
$305,508 or 14%. A 1% decrease in the depletion rate reduced depreciation and
depletion expense by $116,822. The changes in production, noted above, reduced
depreciation and depletion expense by an additional $188,686. The decrease in
the depletion rate was primarily due to relatively higher production from
properties with a relatively lower depletion rate, partially offset by downward
revisions of oil and gas reserves during December 1997.

         The total combined general and administrative expenses decreased to
$1,611,221 in 1997 from $1,976,001 in 1996. This represents a decrease of
$364,780 or 18% from 1996 to 1997. This decrease was primarily due to less staff
time being required to manage the Partnership's operations as a result of the
consolidation of the Predecessor Partnerships.

         In 1996, the Predecessor Partnerships sold their interests in the Grass
Island, Enexco and Comite acquisitions for $235,000, $64,000 and $55,000,
respectively. Gains of $69,731, $61,648 and $21,649, respectively, were
recognized on these sales. The Predecessor Partnerships also sold their
interests in the E.M. Lane well and the Harper #1 well for $57,970 and $55,000,
respectively. Gains of $31,310 and $44,642, respectively, were recognized on
these sales. The Predecessor Partnerships also sold their interests in three
other wells in 1996 for $59,630. These sales resulted in a net gain of $13,409
to the Predecessor Partnerships. The impact of these sales on current and future
revenues is not expected to be material, as such interests represented less than
10% of historical and future net revenues.

         In 1997, the Partnership sold its interest in the North Buck Draw Unit
for $857,120. A gain of $758,969 was recognized on the sale. The Partnership
sold its interest in the Mcbride acquisition for $56,306. A loss of $25,405 was
recognized on the sale. The Partnership also sold its interest in two other
acquisitions for $8,053. A net gain of $8,053 was recognized by the Partnership
from the sales. The impact of these sales on current and future revenues is not
expected to be material, as such interests represented less than 10% of
historical and future net revenues.

CAPITAL RESOURCES AND LIQUIDITY

         The Partnership's cash flow provided by operating, financing and
investing activities is a direct result of the amount of net proceeds realized
from the sale of oil and gas production. Accordingly, the changes in cash flow
from 1996 to 1997 are primarily due to the changes in oil and gas sales
described above. It is the General Partner's intention to distribute
substantially all of the Partnership's available net cash flow to the partners.

         In 1997 and 1996, the Partnership and its Predecessor Partnerships paid
total combined distributions of $4,593,955 and $2,464,947, respectively, to its
limited partners. The Partnership will continue to recover its reserves and
distribute to the limited partners the net proceeds realized from the sale of
oil and gas production after payment of debt obligations. The Partnership plans
to repay the amount owed to the General Partner in 1998. The payment of future
distributions will depend on the Partnership's earnings, financial conditions,
working capital requirements and other factors, although it is anticipated that
regular quarterly distributions will continue through 1998.

         At December 31, 1997, the Partnership had no material commitments for
capital expenditures. The Partnership does not intend to engage in any
significant developmental drilling activity. The Partnership does not intend to
purchase additional properties or fund extensive development of existing oil and
gas properties and, as such, has no long-term liquidity needs. The Partnership's
projected cash flows from operations are expected to provide sufficient funding
to pay its operating expenses and debt obligations.

         In February 1998, Middle Bay Oil Company, Inc., an independent oil and
gas producer, announced a tender offer for all of the outstanding shares of Enex
Resources Corporation ("Enex"), the Partnership's general partner. The tender
offer was accepted by a majority of Enex shareholders and was completed on March
27, 1998.

         The Partnership does not anticipate that it will incur any significant
expenditures to address Year 2000 issues, nor do Year 2000 issues represent a
known material event or uncertainty to the Partnership. To the extent that the
Partnership may be adversely affected by the Year 2000 issues of its suppliers,
customers and other entities, the Partnership does not believe that it will be
more adversely affected than other companies in its industry with similar
operations.

NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1998

         Oil and gas sales for the first nine months decreased from $7,634,183
in 1997 to $4,553,827 in 1998. This represents a decrease of $3,080,356 (40%).
Oil sales decreased by $2,005,993 (45%). A 17% decrease in oil production
reduced sales by $762,544. A 12% decrease in the average oil sales price
decreased oil sales an additional $1,243,449. Gas sales decreased by $1,074,363
(33%). A 24% decrease in gas production decreased sales by $779,804. A 12%
decrease in the average gas sales price decreased gas sales by an additional
$294,559. The changes in the average oil and gas sales price correspond with
changes in the overall market for the sale of oil and gas. The prices of oil and
gas were lower in 1998 versus 1997. The decreases in oil and gas production were
primarily the result of natural production declines.

<PAGE>   95
         Gas plant sales decreased from $806,692 in the first nine months of
1997 to $17,733 the first nine months of 1998. This represents a decrease of
$806,692 or 98%. This decrease was due primarily to the sale of the Dover
Hennessey Gas Plant which was effective January 1, 1998.

         Lease operating expenses decreased from $2,643,098 in the first nine
months of 1997 to $2,148,628 in the first nine months of 1998. The decrease of
$494,470 (19%) is primarily due to the sale of the Lake Decade and McBride
acquisitions in 1997.

         Depreciation and depletion expense increased from $1,327,558 in the
first nine months of 1997 to $1,363,658 in the first nine months of 1998. This
represents an increase of $36,100 (3%). The change in production (noted above)
reduced depreciation and depletion expense by $393,306. This was offset by a 5%
increase in the depletion rate which increased depletion $429,406. The rate
increase was primarily due to downward revisions of the oil and gas reserves
during December, 1997.

         Effective January 1, 1997, the Partnership sold its interests in the
Perkins well in the Burkholder acquisition for $5,940. A gain of $5,940 was
recognized on this sale.

         Effective January 1, 1998, the Partnership sold its interest in the
Dover Hennessey Gas Plant for $1,000,000. A gain of $671,923 was recognized on
the sale. Effective June 1, 1998, the Partnership sold its interest in the
Corkscrew acquisition for $36,000. A loss of $167,302 was recognized on the
sale. Effective July 1, 1998, the Partnership sold its interest in the Brown 1
and 2 wells for $8,000. A gain of $4,171 was recognized on the sale. Effective
September 1, 1998, the Partnership sold its interest in numerous properties in
an August, 1998 auction for $929,063. A gain of $542,881 was recognized on the
sale.

         General and administrative expenses decreased from $1,119,121 in the
first nine months of 1997 to $808,484 in the first nine months of 1998. This
decrease of $310,637 (28%) is primarily due to a reduction in staff as a result
of the consolidation of the Partnership in June, 1997.

CAPITAL RESOURCES AND LIQUIDITY

         The Partnership's cash flow from operations is a direct result of the
amount of net proceeds realized from the sale of oil and gas production.
Accordingly, the changes in cash flow from 1997 to 1998 are primarily due to the
changes in oil and gas sales described above and the sale of oil and gas
properties. It is the General Partner's intention to distribute substantially
all of the Partnership's available cash flow to Unitholders. The Partnership's
"available cash flow" is essentially equal to the net amount of cash provided by
operating, financing and investing activities.

         The Partnership will continue to recover its reserves and distribute to
the partners the net proceeds realized from the sale of oil and gas production
after the payment of its debt obligations. Distribution amounts are subject to
change if net revenues are greater or less than expected. Nonetheless, the
General Partner believes the Partnership will continue to have sufficient cash
flow to fund operations and to maintain a regular pattern of distributions.

         As of September 30, 1998, the Partnership had no material commitments

                        CONSOLIDATED FINANCIAL STATEMENTS
                    DECEMBER 31, 1997 AND SEPTEMBER 30, 1998

NOTE 1.           BASIS OF PRESENTATION

                  The unaudited pro forma consolidated financial statements
reflect the effect of the proposed offer to exchange shares of Series C 10%
convertible preferred stock of Middle Bay for 1,102,631 Partnership Units
representing 100% of the outstanding units of Enex Consolidated Partners, L.P.
(the "Offer"), of which Enex Resources Corporation owns 56.24%. The unaudited
pro forma consolidated financial statements also have been prepared to give
effect to the mergers of Bison Energy Corporation ("Bison") and Shore Oil
Company ("Shore") with Middle Bay effective February 28 and June 30, 1997,
respectively, the acquisition of 1,064,032 shares, or 79.2% of the outstanding
common stock of Enex Resources Corporation effective March 27, 1998, and the
acquisition of substantially all of the assets of Service Drilling Co., L.L.C.
("Service Drilling") effective April 16, 1998. The unaudited pro forma
consolidated financial statements have been prepared to give effect to these
transactions as if they had taken place as of January 1, 1997 with respect to
the unaudited pro forma consolidated statements of operations for the year ended
December 31, 1997 and the nine-month period ended September 30, 1998 and to give
effect to the Offer as if it had taken place on September 30, 1998 with respect
to the unaudited pro forma consolidated balance sheet. Each acquisition or
merger was recorded using the purchase method of accounting.

                  At December 31, 1997, Enex Resources Corporation served as
managing general partner for one limited partnership, Enex Consolidated
Partners, L.P. ("Enex Consolidated Partners" or the "Partnership"). Enex
Resources Corporation has a 4.1% carried revenue interest as the general partner
of Enex Consolidated Partners in addition to its proportional interest as a
limited partner of 55.508%. Enex Consolidated Partners was formed from
thirty-four managed limited partnerships (the "Predecessor Partnerships")
effective June 30, 1997 (the "Consolidation"). For the first six months of 1997,
Enex Resources Corporation served as managing general partner for the
Predecessor Partnerships. Prior to the Consolidation, Enex Resources Corporation
owned greater than 50% of one of the Predecessor Partnerships. Enex Resources
Corporation used pro rata consolidation for those partnerships in which it owned
less than a 50% interest and fully consolidated the partnership in which it
owned greater than 50% interest. Effective June 30, 1997, as a result of the
Consolidation, Enex Resources Corporation owned greater than 50% of the only
partnership it managed. The equity of minority partners in Enex Consolidated
Partners is shown in the historical consolidated financial statements as
"minority interest." From July 1, 1997, the consolidated financial statements of
Enex Resources Corporation include the accounts of Enex Resources Corporation
and its wholly-owned subsidiaries, including Enex Consolidated Partners. Prior
to July 1, 1997, the consolidated financial statements of Enex Resources
Corporation include the accounts of Enex Resources Corporation, its wholly-owned
subsidiaries and its pro rata share of the assets, liabilities, revenues and
expenses of the Predecessor Partnerships.

                  The unaudited pro forma consolidated balance sheet as of
September 30, 1998 includes the historical financial position of Middle Bay Oil
Company, which includes Bison, Shore, Enex Resources


                                     - 89 -

Corporation and Service Drilling, and the pro forma adjustments to give effect
to the Partnership exchange as if it had occurred on September 30, 1998.

                  The unaudited pro forma consolidated statement of operations
for the year ended December 31, 1997 reflects the following: (i) the historical
consolidated statement of operations of Middle Bay; (ii) the combined historical
statements of operations of Bison and Shore prior to their merger with Middle
Bay; (iii) the historical consolidated statement of operations of Enex Resources
Corporation prior to its acquisition by Middle Bay; (iv) the portion of the
historical statement of operations of the predecessor partnerships for the six
months ended June 30, 1997 which was not pro rata consolidated in the historical
consolidated statement of operations of Enex Resources Corporation for the year
ended December 31, 1997; and (v) the related pro forma adjustments for the Bison
and Shore mergers, the Enex Resources Corporation and Service Drilling
acquisitions and the Partnership exchange. As discussed in (iv), the unaudited
pro forma statement of operations for the year ended December 31, 1997 requires
a separate column to reflect the pro rata results of operations of the
Predecessor Partnerships that are attributable to the limited partners other
than Enex Resources Corporation for the period prior to the June 30, 1997
Consolidation, as such amounts are not included in the consolidated statement of
operations of Enex Resources Corporation for the year ended December 31, 1997.

                  The unaudited pro forma consolidated statement of operations
for the nine months ended September 30, 1998 reflects (i) the historical
consolidated statement of operations of Middle Bay; (ii) the historical
consolidated statement of operations of Enex Resources Corporation for the
period ended March 27, 1998, in which the historical consolidated statement of
operations of the Partnership is consolidated for the same period. The
historical consolidated statements of operations of Enex Resources Corporation
for the period from March 27, 1998 to September 30, 1998 is included in the
historical consolidated statement of operations of Middle Bay for the nine
months ended September 30, 1998, as the acquisition of 79.2% of Enex Resources
Corporation closed on March 27, 1998; and (iii) the related pro forma
adjustments for the Partnership exchange and the Service Drilling acquisition
prior to its effective date of April 16, 1998.

NOTE 2.           PRO FORMA ENTRIES

                  Pro Forma Adjustments for the Partnership Exchange

                  It is anticipated that during December, 1998, the Company will
close an offer to the Partnership whereby it will issue a total of 2,300,000
shares of Middle Bay Series C 10% convertible preferred stock ($5.00 per-share
liquidation preference) in exchange for all of the right, title and interest to
the units of Partnership interest held by Investors and Enex Resources
Corporation. The number of the shares outstanding attributable to Investors and
the minority interest owners of Enex Resources Corporation (20.8%) is 1,275,532,
representing the 269,052 shares attributable to the minority interest (20.8%)
owners of Enex Resources Corporation's 56.24% ownership of the Partnership plus
the 1,006,480 shares attributable to the Investors' 43.76% of the Partnership.

                  Pro Forma Adjustments for the  Service Drilling Acquisition

                  On April 16, 1998, the Company closed an Asset Purchase
Agreement with Service Drilling and certain affiliates, whereby the Company
acquired substantially all of the assets of Service Drilling and


                                     - 90 -
<PAGE>   103
its affiliates in exchange for the Company's common stock and cash. Pursuant to
the Agreement, the Company issued 666,000 shares of its common stock and paid
aggregate cash consideration of $6,500,000, $5,500,000 of which was funded
through borrowings on Middle Bay's revolving line of credit. The acquisition was
accounted for as a purchase of substantially all of the assets of Service
Drilling and as a result of the purchase method of accounting, Middle Bay's cost
of acquiring the assets of Service Drilling was allocated to the assets acquired
based on their fair values.

                  Pro Forma Adjustments for the Enex Acquisition

                  On March 27, 1998, in exchange for 79.2% ownership, Middle Bay
acquired 1,064,032 shares of the common stock of Enex for a total purchase price
of $17,061,00, including $15,960,480 or $15 cash per share, assumption of an
additional liability of $789,000 and issuance of 33,825 common shares of the
Company for finders fees, pursuant to Middle Bay's tender offer (the "tender
offer") which began on February 19, 1998. The acquisition was accounted for as a
purchase of 79.2% of Enex and as a result of the purchase method of accounting,
Middle Bay's cost of acquiring the 79.2% of Enex was allocated to the assets and
liabilities acquired based on estimated fair values.

                  Pro Forma Adjustments for the Bison and Shore Mergers

                  Middle Bay and Bison entered into a merger agreement whereby
Bison was merged into and continues to exist as a wholly-owned subsidiary of
Middle Bay, effective February 28, 1997.

                  On June 20, 1997, Middle Bay and Shore entered into a merger
agreement whereby Shore was merged into and continues to exist as a wholly-owned
subsidiary of Middle Bay, effective June 30, 1997.

                  The mergers were accounted for as purchases of Bison and Shore
by Middle Bay and as a result of the purchase method of accounting, Middle Bay's
cost of acquiring Bison and Shore was allocated to the assets and liabilities
acquired based on estimated fair values.

                  The accompanying unaudited pro forma combined financial
statements reflect the following adjustments:

                  (1) To record the exchange of 2,300,000 shares of Middle Bay
Series C 10% convertible preferred stock ($5.00 per-share liquidation
preference) and related costs for the outstanding Partnership Units, less the
1,024,468 shares owned by Enex Resources Corporation which are not attributable
to the minority interest owners of Enex Resources Corporation (20.8%), equal to
1,275,532 third-party shares. The allocation of the purchase price to the
acquired assets and liabilities is preliminary and, therefore subject to change.
Any future adjustments to the allocation of the purchase price are not
anticipated to be material to the unaudited pro forma financial statements.

                  (2) To record the operating income and expenses related to the
oil and gas properties purchased from Service Drilling.

                  (3) To remove management income and related expenses charged
in accordance with a contractual arrangement whereby Bison performed accounting
and administrative for another entity


                                     - 91 -
<PAGE>   104
previously acquired by Middle Bay. Subsequent to the merger, Bison no longer
performed such accounting and administrative functions under the contract.

                  (4) To adjust depreciation, depletion and amortization to
reflect Middle Bay's purchase price allocated to the property and equipment
acquired from the Partnership, Service Drilling, Enex Resources Corporation,
Bison and Shore using the unit of production method utilized by Middle Bay.

                  (5) To record interest expense on the debt incurred as a
result of the Service Drilling and Enex Resources Corporation acquisitions, and,
for the year ended December 31, 1997, to record the reduction of $69,999 in
interest expense on the debt retired in the Shore merger through the issuance of
Series A preferred stock (see note (9)).

                  (6) To adjust minority interest related to the acquisitions of
the Partnership and Enex Resources Corporation by Middle Bay.

                  (7) To adjust the provision for income taxes for the change in
taxable income as a result of the acquisitions at assumed effective tax rates of
33% and 35% for the nine months ended September 30, 1998 and the year ended
December 31, 1997, respectively.

                  (8) To remove equity in net earnings of equity investees that
were not purchased in the Bison merger.

                  (9) To record the preferred stock dividends on the 1,275,532
shares of Series C 10% convertible preferred stock ($5.00 per-share liquidation
preference) issued in connection with the Partnership Exchange other than 79.2%
of the preferred stock dividends of Enex Resources Corporation which will be
eliminated in consolidation of Middle Bay's financial statements and, for the
year ended December 31, 1997, to record the preferred stock dividends paid on
the Series A convertible preferred stock issued for the cash portion of the
Bison merger and issued in connection with the retirement of debt assumed in the
Shore merger.

                  (10) To reflect the impact on the weighted average common
shares outstanding for the 2,488,889 shares of Middle Bay common stock issued in
conjunction with the Bison and Shore mergers, the 666,000 shares issued in
conjunction with the Service Drilling acquisition and the 33,825 shares issued
in conjunction with the Enex acquisition. Shares issuable upon exercise of
options and upon the conversion of preferred stock are excluded from the
computations of the diluted weighted average common shares outstanding because
their effects would be anti-dilutive.

                  (11) To reflect the issuance of 2,488,889 shares of Middle Bay
common stock in conjunction with the Bison and Shore mergers, the 666,000 shares
issued in conjunction with the Service Drilling acquisition and the 33,825
shares issued in conjunction with the Enex acquisition. Pro forma basic net
income (loss) per common share information is computed by dividing net income
(loss), applicable to common stock by the pro forma weighted average common
shares outstanding.

                             BUSINESS OF MIDDLE BAY

         Middle Bay Oil Company, Inc. ("Middle Bay" or the "Company") is an
independent oil and gas company engaged in the exploration, development and
production of oil and gas in the contiguous United States. Middle Bay's strategy
focuses on increasing its reserves of crude oil and natural gas by the
acquisition and development of proved oil and gas properties primarily in the
Mid-Continent and Gulf Coast regions. The Company believes the current period
reflects historically low market prices for oil and gas and is focusing its
efforts on increasing reserves so that it will be well positioned to benefit in
the event of any future increases in demand for natural gas and oil. Consistent
with these efforts, the Company is participating on a limited basis in drilling
and development activities in other geographic regions of the contiguous United
States. In November, 1997, Middle Bay relocated its principal executive offices
to 1221 Lamar Street, Suite 1020, Houston, Texas 77010. The Company's mailing
address is P.O. Box 53448, Houston, Texas 77052-3448.
Its telephone number is (713) 759-6808.

         Middle Bay's oil and gas reserves are principally in long-lived fields
with well-established production histories. Middle Bay's net Proved Reserves,
estimated as of December 31, 1997 by applying S.E.C. assumptions, consisted of
approximately 18,419 million cubic feet of gas and 2,933 thousand barrels of
oil, with an aggregate present value before income taxes, at a 10% discount, of
$30,179,000. Approximately 80% of the reserves are classified as proved
developed producing, 7% are proved developed non-producing and 13% are proved
undeveloped. On an equivalent barrel basis, the proved reserves are 55% gas.
Recoverable volumes of gas increased 105% and recoverable volumes of oil
increased 111% over 1996 volumes. The PV 10% of the oil and gas reserves
increased 34% over the 1996 amount of $22,465,000. The reserves are located
primarily in Alabama, Kansas, Louisiana, Oklahoma and Texas. A substantial
portion of the Company's natural gas production and Proved Reserves consist of
high BTUgas which, because of its rich liquid content and its proximity to
processing and transmission facilities, is generally sold at a premium to Gulf
Coast and Mid-Continent spot market prices. Substantially all of Middle Bay's
oil production is sold at market responsive prices. All of the Company's gas
production, except for the gas sold in the Spivey Field, is sold at market
responsive prices.

BUSINESS STRATEGY

         Middle Bay's present business strategy is to concentrate on expanding
its asset base and cash flow primarily through emphasis on the following
activities:

             -    Increasing production, cash flow and asset value by acquiring
                  Producing Properties with stable production rates, long
                  reserve lives and potential for exploitation and development;

             -    Building on the Company's existing base of operations by
                  concentrating its development activities in its primary
                  operating areas in  the Gulf Coast and the Mid-continent
                  Regions;

             -    Acquiring additional properties with potential for
                  developmental drilling to maintain a significant inventory of
                  undeveloped Prospects and to enhance Middle Bay's foundation
                  for future growth;


                                     - 93 -
<PAGE>   106
             -    Serving as operator of its wells to ensure technical
                  performance and reduce costs;

             -    Expanding its relationships with major and large independent
                  oil and gas companies to access their undeveloped properties,
                  seismic data and financial resources;

             -    Managing financial risk and mitigating technical risk by:

                  -    drilling in known productive trends with multi-horizon
                       geologic potential;

                  -    diversifying investment over a large number of wells in
                       the Company's primary operating areas;

                  -    developing properties that provide a balance between
                       short and long reserve lives; and

                  -    keeping a balanced reserve profile between oil and gas;
                       and

             -    Maintaining low general and administrative expenses and
                  increasing economies of scale to reduce per unit operating
                  costs and reserve acquisition costs.

ACQUISITION POLICY

         Middle Bay continues to pursue a program of actively acquiring
producing oil and gas properties, with the goal of increasing cash flow,
reserves and value for the long-term benefit of its stockholders.

         Middle Bay utilizes an acquisitions' screening approach with its
experienced management and technical staff which reviews potential property
against multiple criteria, both quantitative and subjective. The Company
generally seeks Producing Properties with established production histories.
Middle Bay may operate the property acquired; however, Middle Bay also considers
nonoperated property acquisitions.

         In evaluating Producing Properties for potential acquisition,
production history, reservoir characteristics and available geologic data and
interpretations are analyzed to determine estimates of proved and other reserves
and cash flows expected to be recovered. Also evaluated are specific risks and
economic considerations associated with the property, including environmental
liabilities, risks of curtailment, condition of equipment and potential for
additional development opportunities. Sales contracts, operating agreements and
other contractual commitments, including take-or-pay clauses, market-out
clauses, gas balancing agreements, transportation agreements and reversionary
interests that may affect the cash flows from the property are also reviewed.

DRILLING ACTIVITIES

         Middle Bay has participated in drilling operations primarily in Texas,
Louisiana and Kansas. The Company's drilling activity increased significantly in
1996 when Middle Bay executed the Brigham Agreement. Middle Bay's drilling is
funded principally from cash flow and is highly dependent on the price of oil
and gas. If the price of oil continues to remain at or near the March, 1998
levels, the amount of funds available for drilling could be reduced.


                                     - 94 -
<PAGE>   107
         For the twelve months ended December 31, 1997, Middle Bay drilled 42
gross wells; 23 Development Wells and 19 Exploratory Wells. Seventeen of the
Development Wells and 8 of the Exploratory Wells were successful. The Company's
drilling was concentrated in Kansas, Louisiana and Texas, where 14, 12 and 7
wells were drilled, respectively. The majority of the Kansas wells were
Development Wells drilled in the Spivey Field (the "Spivey Field"). Two
unsuccessful Exploratory Wells were drilled in the Reflection Ridge Prospect in
Stanton County, Kansas. No further exploration is anticipated on the Reflection
Ridge Prospect. For the three months ended March 31, 1997, Middle Bay
participated in the drilling of 12 Exploratory Wells through the Brigham
Agreement. The Brigham Agreement ended March 31, 1997.

         Shore Oil Company #1, an Exploratory Well being drilled as of December
31, 1997, was found to be unsuccessful in February, 1998. This Exploratory Well
was drilled on the Raceland Prospect in Lafourche Parish, Louisiana which is
located on the fee mineral acreage acquired in the Shore Merger. Middle Bay had
prepaid approximately $300,000 in drilling cost as of December 31, 1997 and
expensed the costs in the fourth quarter when it was determined that the well
was abandoned.

         For the twelve months ended December 31, 1996, Middle Bay drilled 54
wells, 5 Developmental Wells and 49 Exploratory Wells. Four of the Developmental
Wells and 31 of the Exploratory Wells were successful. For the nine months ended
December 31, 1996, Middle Bay participated in the drilling of 49 Exploratory
Wells through the Brigham Agreement. Forty wells were drilled in Texas, seven in
Oklahoma, one in Kansas and one in New Mexico. Middle Bay also participated in
the drilling of four Developmental Wells in the Frymire Waterflood Unit in Nolan
County, Texas, three of which were successful and one of which was a dry hole.
One successful Developmental Well was drilled in the Campbell Field in Major
County, Oklahoma.

         Drilling activities during 1997 added 22 thousand barrels of oil and
705 million cubic feet of gas with estimated future net revenues, discounted at
10%, of $851,000. Drilling activities during 1996 added 76 thousand barrels of
oil and 392 million cubic feet of gas with estimated future net revenues,
discounted at 10%, of $1,966,000. For the years 1996 and 1997, oil and gas
reserves discovered through current year drilling accounted for 11% and 3%,
respectively, of the year-end reserve value.

         In 1995, Middle Bay entered into a joint development agreement, the
Quarry Prospect, with Chesapeake Operating, Inc. ("COI"). The agreement covers a
600-acre block of leases in Lea County, New Mexico assembled by the Company and
COI. The Quarry Prospect is believed to be a large strawn algal mound that was
initially identified through 2-D seismic and further defined using 3-D seismic
testing. In 1997, the Company acquired additional leases in the prospect and
sold 50% of the Quarry Prospect. Middle Bay and COI together retained 50% of the
Quarry Prospect. If COI elects not to participate, Middle Bay's interest will be
increased to 50%. The first well on the Quarry Prospect is expected to spud in
the second quarter of 1998 and will cost the Company approximately $141,000 to
drill and $66,000 to complete (assuming a 25% working interest).

         In July 1997, Middle Bay executed an exploration agreement with Brigham
Exploration Company ("Brigham") for a 3-D seismic exploration project on the
Hawkins Ranch (the "Ranch") in Matagorda


                                     - 95 -
<PAGE>   108
County, Texas. The Ranch has been lease optioned for a 54 square mile 3-D
seismic survey. Middle Bay purchased a 25% working interest through the lease
selection phase of the project for $225,000.

         Middle Bay purchased a 12.5% working interest in the Sherburne Prospect
in Point Coupee Parish, Louisiana, in October, 1997 (the "Sherburne Prospect").
The Sherburne Prospect consists of approximately 10,000 acres that are
prospective in the Frio, Cockfield, Sparta and Wilcox formations. The acreage is
located in Southwest Point Coupee Parish between Krotz Springs Field and the
Fordoche Field. Production is at depths from 6,500' to 15,500'. Swift Energy
Company has a 62.5% working interest and will be the operator. A private company
holds the remaining 25%. The first well was spud on March 11, 1998 with an
estimated dry hole cost to Middle Bay of approximately $300,000.

         In the foreseeable future, Middle Bay's primary drilling focus will be
its participation in the Sherburne Prospect, the Ranch Prospect, the Quarry
Prospect and the development of the Spivey Field. Middle Bay expects to drill
several Development Wells in the Spivey Field in Kansas in 1998. Middle Bay also
expects several wells to be drilled on the Shore mineral acreage in South
Louisiana in 1998. In addition, Middle Bay is continually evaluating Prospects
originated by its staff, other independent geologists or other oil and gas
companies. If review of a certain Prospect indicates that it may be geologically
and economically attractive, then Middle Bay will attempt to obtain a Lease on
the applicable acreage or commit to a Working Interest in the drilling Prospect.
When the Company does participate in a Prospect, it will typically acquire a
fractional Working Interest in the Prospect, which may range from small
percentage interests in more expensive exploratory Prospects to a majority
interest in a lower cost or development Prospect. Middle Bay believes that such
participation, which is common practice in the oil and gas industry, allows for
further diversification and reduction of risk.

ACQUISITIONS AND MERGERS

         Since its formation, Middle Bay has grown primarily through
acquisitions of proven oil and gas reserves. For the years 1993 through 1997,
acquisitions of reserves accounted for 64%, 5%, 35%, 34% and 80% of the year-end
discounted reserve value, respectively. Middle Bay has financed its acquisitions
primarily by utilizing its credit facility with the Bank and issuing common and
preferred stock. (See "Middle Bay Financing," below.)

         In August 1997, Middle Bay acquired a 5.74% working interest in proved
reserves in the Riceville Field in Vermilion Parish, Louisiana for approximately
$3.5 million. The acquisition was financed with $3 million in loan proceeds and
the remainder from cash on hand. The Riceville Acquisition added approximately
63 thousand barrels of oil and 2,955 million cubic feet of gas to the Company's
proved reserves. A portion of the reserves is proved undeveloped. The Riceville
Acquisition had a PV 10% of approximately $5.3 million, using December 31, 1997
prices.

         The Shore Merger in June, 1997 added approximately 965 thousand barrels
of oil and 1,364 million cubic feet of gas to Middle Bay's proved reserves. A
portion of the reserves consists of proven behind pipe and proven undeveloped
reserves. The Shore Merger had a PV 10% of approximately $6.0 million, using


                                     - 96 -
<PAGE>   109
December 31, 1997 prices. The Shore Merger also added approximately 42,000 net
acres of minerals located in South Louisiana, which were valued at $3.6 million
at June 30, 1997.

         The Bison Merger in February, 1997 added approximately 951 thousand
barrels of oil and 7,791 million cubic feet of gas to Middle Bay's proved
reserves. A portion of the reserves consists of proven behind pipe and proven
undeveloped reserves. The Bison Merger had a PV 10% of approximately $8.9
million, using December 31, 1997 prices.

         The NPC Merger in December, 1996 added approximately 503 thousand
barrels of oil and 3,139 million cubic feet of gas to Middle Bay's proved
reserves. A portion of the reserves consists of proven behind pipe and proven
undeveloped reserves. The NPC Merger had a PV 10% of approximately $6.0 million,
using December 31, 1996 prices.

         Middle Bay is currently in the process of evaluating various corporate
acquisitions and potential mergers in exchange for common stock of the Company.
Management believes that corporate acquisitions and mergers are the fastest way
to achieve Middle Bay's growth goals. In addition to achieving what management
perceives to be a proper critical mass, potential corporate acquisitions or
mergers are also considered as opportunities to build a more diverse oil and gas
property base for further development and exploration.

         The price of oil has declined significantly since December 31, 1997
and, in 1998, reached the lowest level in ten years. The posted price of WTI
crude declined from approximately $15 per barrel on December 31, 1997 to
approximately $9.50 per barrel on November 24, 1998. If oil prices remain at or
near these levels, the funds available for acquisitions could be reduced.

COMPETITION, MARKETS AND REGULATION

         Competition in the exploration and property acquisition markets is
intense. In seeking to obtain desirable Leases and exploration Prospects, Middle
Bay faces competition from both major and independent oil and gas companies, as
well as from numerous individuals. Many of these competitors have substantial
financial resources available to them, which makes for increased competition.

         The ability of Middle Bay to market oil and gas from its wells will
depend upon numerous factors beyond its control, including, but not limited to,
the extent of domestic production and imports of oil and gas, the proximity of
Middle Bay's production to existing pipelines, the availability of capacity in
such pipelines and state and federal regulation of oil and gas production. There
is no assurance that the Company will be able to market all of the oil or gas
produced by it or that favorable prices can be obtained for the oil and gas it
produces. In view of the uncertainties affecting the supply and demand of oil
and gas, Middle Bay is unable to accurately predict future oil and gas prices
and demand, or the overall effect they will have on the Company.

         Numerous federal and state laws and regulations affect Middle Bay's
operations. In particular, oil and gas production operations are affected by tax
and other laws relating to the petroleum industry and any


                                     - 97 -
<PAGE>   110
changes in such laws and regulations. Some of the rules and regulations carry
substantial penalties for failing to comply. The regulatory burden on the oil
and gas industry increases the Company's cost of doing business. Middle Bay's
activities are also subject to numerous federal, state and local environmental
laws and regulations governing the discharge of materials. In most cases, the
applicable regulatory requirements relate to water and air pollution control or
solid waste management measures. Middle Bay believes the recent trend toward
stricter standards in environmental legislation, regulation and enforcement will
continue. To date, these laws have not had a significant impact on the Company
but no assurance can be given as to the effect of these laws on the Company in
the future.

EMPLOYEES

         As of September 30, 1998, Middle Bay employs twenty-seven full-time
persons. Middle Bay employs eleven full-time persons in its Houston, Texas
office, including four executive officers, whose functions are associated with
management, engineering, geology, land and legal, accounting, financial planning
and administration. Middle Bay employs four full-time persons in its Wichita,
Kansas office, including one executive officer, a geologist, an engineer and an
administrative assistant. Middle Bay also employs one full-time supervisor for
well operations in Oklahoma and one full-time accountant in Mobile, Alabama.

PROPERTIES

         Real Estate Properties

         Middle Bay owns a historic home in Mobile, Alabama which previously
served as its corporate office before the Company's relocation to Houston, Texas
in November 1997. Middle Bay has listed the property for sale.

         Oil and Gas Properties

         More than 95% of Middle Bay's oil and gas properties, reserves and
activities are located onshore in the continental United States, primarily in
Alabama, Kansas, Louisiana, Oklahoma and Texas. Estimates of total proved net
oil or gas reserves have not been filed with or included in reports to any
federal authority or agency. There are no quantities of oil or gas subject to
long-term supply or similar agreements with foreign governmental authorities.

         Middle Bay's largest oil and gas property, in terms of dollar value, is
the Spivey Field acquired in the Bison Merger. The Spivey Field, located in
Kingman and Harper Counties, South Central Kansas, was discovered in 1949.
Development of oil and gas reserves from the Mississippian Chert Formation, at
an average drilling depth of 4,250 feet, has been continual since discovery.
Currently, approximately 585 active wells produce in the field. Great lateral
extent, thick pay sections, and long-lived production characterize the
reservoir.


                                     - 98 -
<PAGE>   111
         The Spivey Field has cumulative gas production of over 75,000 million
cubic feet. Gas is marketed to the spot markets and to the Spivey Gas Plant (the
"Plant"). Over 95% of Company gas is sold to the Plant under a life of the lease
casinghead tailgate gas contract. Middle Bay owns approximately 11.5% ownership
in the Plant and related gathering system. Warren Petroleum Company, L.P., and
NGC Corporation jointly operate the Plant. Ownership in the Plant is
redetermined annually, based on owner's throughput relative to total throughput.
Plant liquids (propane, butane and natural gas) are marketed from the Plant to
Murphy Energy. Residue gas is sold to KGE (f/k/a Kansas Power and Light) for a
tailgate price of $2.91 per Mcf. The tailgate contract calls for an annual
escalation of $0.02 per Mcf. The Btu factor for the residue gas is 1.042. Plant
owners also receive the benefit of buying, stripping and reselling "non-owner"
field gas.

         The Spivey Field has cumulative oil production of over 66.6 million
barrels of oil. Lease oil is marketed to Koch Oil Company, via truck, and a
bonus above posted prices is received.

         Middle Bay operates approximately 80 wells in the Spivey Field from a
field office in Attica, Kansas, staffed by one foreman and two Company pumpers.
All oilfield services are present in the field. Exploration, engineering and
land functions are directed from the division office located in Wichita, Kansas.
Middle Bay is continually developing its acreage position of approximately 8,500
gross acres.

         As of December 31, 1997, Middle Bay has identified and independent
engineers have evaluated twenty-two proven undeveloped locations in the Spivey
Field with a PV 10% value of approximately $2.4 million. At December 31, 1997,
the Plant was valued by independent engineers at $2.9 million PV 10%.

         The following table shows proved oil and gas reserves by major field
for Middle Bay's largest producing fields at December 31, 1997. The values
represent the present value of estimated future net cash flows before income
taxes, discounted at 10%, assuming unescalated expenses and prices of $16.18/Bbl
and $2.54/MMBtu attributable to proved reserves at December 31, 1997, as
determined by independent petroleum engineers. See "Experts."

         As of December 31, 1997, the Bank has a first mortgage on all of the
fields listed in the above table. The Bank also has a first mortgage on numerous
additional fields not individually listed above which in total gives the Bank a
first mortgage on approximately 75% of Middle Bay's total reserves (PV 10%) of
$30,179,000 before income tax. Middle Bay is obligated, within five days of
request by the Bank, to grant the Bank a first and prior mortgage on any oil and
gas properties owned or acquired by Middle Bay.

         Louisiana Fee Mineral Acreage

         In the Shore Merger, Middle Bay acquired approximately 42,321 net
mineral acres, situated in Terrebonne, Lafourche and St. Mary Parishes in
Louisiana. Of the total acreage, 39,769 acres are non-producing and the
remainder is held by production under existing leases. The nonproducing acreage
is located in the following parishes: 20,587 in Terrebonne (Montegut and Houma
areas), 11,128 acres in Lafourche (Raceland and Valentine areas) and 8,054 acres
in St. Mary Parish (Charenton area). The nonproducing acreage currently under
lease and/or option has expiration dates as follows: 17,835 acres in 1998 and
5,722 acres in 2000. As of December 31, 1997, 16,212 acres were not under lease.
Royalty interest in the leases covering the nonproducing minerals ranges from
20% to 25%. The mineral servitude prescription dates are estimated by Middle Bay
to be as follows: 620 acres prescribed in 1997, 6,226 acres in 1999, 5,286 acres
in 2002, 4,145 acres in 2004, 1,121 acres in 2005, 1,145 acres held in
perpetuity and the remaining acreage has prescription interrupted by production.
Effective April 1, 1992, Shore Oil Company sold the production rights under
tracts producing at that time and does not receive royalty income from the sale
of oil or gas on those tracts. Over 80% of the nonproducing minerals have been
covered by 3-D seismic shot by third parties and provided to Middle Bay at no
cost. During the period July 1, 1997 through December 31, 1997, Middle Bay
received approximately $975,000 in lease bonus, delay rental and

seismic option income on the acreage. An independent oil and gas engineering
firm valued the acreage as of June 30, 1997 at $3,627,000. One unsuccessful
Exploratory Well in Lafourche Parish, the Shore Oil Company #1, was drilled on
the fee mineral acreage in 1997 and abandoned in February, 1998.

         Productive Wells and Acreage

         The following table depicts the number of gross and net producing wells
and related Developed and Undeveloped Acreage in which Middle Bay owned an
interest for the period ended December 31, 1997 Undeveloped Acreage is oil and
gas acreage (including, in certain instances, rights in one or more horizons
which may be penetrated by existing well bores, but which have not been tested)
to which Proved Reserves have not been assigned by independent petroleum
engineers.

         Middle Bay's net Developed Acreage is located primarily in Oklahoma,
Texas, Alabama, New Mexico and Kansas. Middle Bay's net Undeveloped Acreage is
located in Kansas.

          Reserves

          Note 11 to Middle Bay's financial statements presents, among other
disclosures prepared pursuant to Statement of Financial Accounting Standards No.
69, the estimated net quantities of Middle Bay's proved oil and gas reserves and
the standardized measure of discounted future net cash flows attributable to
such reserves as of December 31, 1997. At December 31, 1997, Middle Bay's net
Proved Reserves consisted of 2,933 thousand barrels of oil and 18,419 million
cubic feet of gas, and net Proved Developed Reserves consisted of 2,580 thousand
barrels of oil and 14,251 million cubic feet of gas. At December 31, 1997, the
present value discounted at 10% for Middle Bay's Proved oil and gas reserves,
before income taxes, was approximately $30,179,000. (See Note 11 to Middle Bay's
financial statements for additional detail on the Company's oil and gas
reserves.) Management of Middle Bay, however, cautions against using this data
to determine the fair value of the Company's oil and gas properties or for any
other purpose because the price of oil and gas can be volatile. The present
value was computed using December 31, 1997 base oil prices of $16.18 per Bbl and
base gas prices of $2.54 per MMBtu. Base prices were adjusted for certain
properties that either received a price above or below the base price. There
were no estimates or reserve reports of Middle Bay's proved oil and gas reserves
filed with any governmental authority or agency during the year ended December
31, 1997.

          The following table sets forth the standardized measure (in thousands
of dollars) of future net cash flows of Proved Reserves and total recoverable
volumes of oil and gas from Proved Reserves attributable to Middle Bay's
interest in oil and gas wells for the years ended December 31, 1997 through
1995:

</TABLE>

        The increases in the standardized measure from 1995 to 1996 and 1996 to
1997 are due primarily to the NPC Merger in 1996 and the Bison and Shore Mergers
and Riceville Acquisition in 1997. For a detail of changes in oil and gas
reserves for the year, refer to Note 11 to Middle Bay's financial statements.

(1)      The Standardized Measure of Discounted Future Net Cash Flows prepared
         by the Company represents the present value of future net revenues
         after income taxes discounted at 10%.

         The reserve data set forth herein represents only estimates. Reserve
engineering is a subjective process of estimating underground accumulations of
crude oil and natural gas that cannot be measured in an exact manner. The
accuracy of any reserve estimate is a function of the quality of available data
and of engineering and geological interpretation and adjustment. As a result,
estimates of different engineers often vary. In addition, results of drilling,
testing and production subsequent to the date of an estimate may justify
revisions of such estimates. Accordingly, reserve estimates often differ from
the quantities of crude oil and natural gas that are ultimately recovered.
Estimates of economically recoverable oil and natural gas reserves and of future
net revenues are based upon a number of variables and assumptions, including
future prices of oil and gas, all of which may vary considerably from actual
results. The reliability of such estimates is highly dependent upon the accuracy
of the assumptions from which they were based.

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


                       CORPORATE GOVERNANCE OF MIDDLE BAY

         The Middle Bay Board of Directors has the responsibility for
establishing broad corporate policies and for the overall performance of the
Company, taking into consideration the interests of all shareholders. Members of
the Board are kept informed of the Company's business by various reports sent or
communicated to them regularly, as well as by operating and financial reports
made at Board and Committee meetings by the President and other officers. During
1997, the full Board met three times. The Board has two Committees, an Audit
Committee and a Compensation Committee. The Audit Committee met one time, and
the Compensation Committee met twice.

         The Audit Committee's duties include recommending to the Board the
selection of a firm of independent public accountants for approval by the
shareholders at their Annual Meeting. In addition, the Committee confers with
Middle Bay's independent public accountants to review the plan and scope of
their proposed audit, as well as their findings and recommendations upon the
completion of the audit. The Committee meets with the independent public
accountants and with appropriate Company financial personnel regarding the
Company's internal controls and financial policies. The Audit Committee
currently consists of Gary R. Christopher, Frank E. Bolling, Jr. and Alvin V.
Shoemaker. No member of the Audit Committee is an officer or employee of Middle
Bay.

         The Compensation Committee is responsible for establishing and
reviewing policies governing executive salaries, bonus and incentive
compensation and the terms and conditions of employment of executives of Middle
Bay. In addition, the Committee is responsible for the oversight of the
Company's 1995 Stock Option and Stock Appreciation Rights Plan and similar or
other plans which may be maintained from time to time by the Company and has
authority to grant options and awards under Middle Bay's 1995 Stock Option and
Stock Appreciation Rights Plan, and oversees the Company's SEP/IRA retirement
plan, the net profits interest incentive compensation plan established by Middle
Bay in 1995 and the 40l(k) plan established in 1997 (see "Corporate Governance
of Middle Bay - Executive Compensation"). The Committee coordinates with the
appropriate financial, legal and administrative personnel of Middle Bay, as well
as outside experts retained in connection with the administration of these
plans. The Compensation Committee currently consists of John J. Bassett,
President and Chief Executive Officer, and Messrs. Edward P. Turner, Jr. and
Frank E. Bolling, Jr., neither of whom is an officer or employee of Middle Bay.

         During 1997, all incumbent directors attended all of the meetings of
the Board of Directors. Attendance at those meetings was 100%. Attendance at the
Committee meetings was 100%.

          Compensation Under Plans

          Middle Bay established a SEP/IRA retirement plan (the "Plan") in 1993
which allows for a maximum discretionary Company contribution of 15% of total
wages paid to employees for the year. For the years ended December, 1997 through
1995, Middle Bay contributed a total of $51,500, $5,000 and $30,000,
respectively, to the Plan, including $32,064, 3,068 and $18,505 for all
executive officers as a group since the Plan's inception.

          Middle Bay established a 401(k) plan in October, 1997, which allows
for voluntary contributions by the employees and the employer. No Company
contributions were made in 1997.

          In March, 1995, the Board of Directors adopted an employee incentive
compensation plan whereby the proceeds equivalent to 1% net profits interest
(the "net profits interest") in all oil and gas properties, drilling prospects
and acquisitions and divestitures acquired or made after January 1, 1994 are
paid into a fund for incentive compensation awards to eligible employees.

          The net profits interest on property acquisitions and drilling
prospects are calculated on the monthly gross profit which is defined as
revenues from oil and gas sales, less direct operating expenses, attributable to
the Company's working or royalty interest in an individual property. Direct
operating expenses include


                                    - 111 -
<PAGE>   124
landowner's royalty, overriding royalty and all costs of production, equipment,
operating expenses and taxes. On drilling prospects, the net profits interest
will not include costs of drilling, testing and completing the well, the costs
of acreage and costs of geological or geophysical work. For divestitures, the
net profits interest will be calculated on the gross sales price, less any
direct costs of the sale of an individual property.

          To qualify for an award as an "eligible employee," as presently
established by the Compensation Committee, an employee must be employed by
Middle Bay on October 1 and December 31 of the calendar year and have been
recommended by the Compensation Committee to receive an award. For the years
ended December 31, 1996 and 1995, Middle Bay paid $6,916 and $30,000,
respectively, to employees through the employee incentive plan, including $4,897
and $21,245 for all executive officers as a group. No amount was paid into the
employee incentive plan in 1997.

          Middle Bay has no other retirement, pension/profit-sharing or other
deferred compensation.

          Option Grants in Last Fiscal Year

          The 1995 Stock Option and Stock Appreciation Rights Plan (the "Plan")
is administered by the Compensation Committee (the "Committee") of the Board of
Directors. At least two members of the Committee must be disinterested
nonemployee directors. The Committee is authorized to determine the employees,
including officers, to whom options or rights are granted. Each option or right
granted shall be on such terms and conditions consistent with the Plan as the
Committee may determine, but the duration of any option or right shall be not
greater than ten years or less than five years from the date of grant.

          Options or rights grants shall be made under the Plan only to persons
who are officers or salaried employees of Middle Bay or are nonemployee
directors. The aggregate number of shares of common stock of the Company which
could be subject to options or rights under the Plan during 1997 was 500,000.
During the fiscal year ended December 31, 1997, options covering 295,000 shares
were issued under the Plan.

          The option price of shares covered by options granted under the Plan
may not be less than the fair market value at the time the option is granted.
The option price must be paid in full in cash or cash equivalent at the time of
purchase or prior to delivery of the shares in accordance with cash payment
arrangements acceptable to the Committee. If the Committee so determines, the
option price may also be paid in shares of the Company's common stock already
owned by the optionee. The Committee has discretion to determine the time or
times when options become exercisable, within the limits set forth in the Plan.
All options and rights granted under the Plan will, however, become fully
exercisable if there is a change in control (as defined in the Plan) of Middle
Bay.

          The following table provides certain information with respect to all
options granted during the fiscal year ended December 31, 1997 to any executive
officer or director of Middle Bay; 295,000 options were granted under the Plan
and 225,000 were granted outside of the Plan:

EMPLOYMENT AGREEMENTS

         Mr. Bassett and Mr. Hammons in January, 1997, signed employment
agreements with Middle Bay which extend through January 31, 2002 and January 31,
2000, respectively, with automatic one-year extensions upon each anniversary
date of the employment agreement thereafter unless either party gives at least
30 days' notice of termination. Each employment agreement is terminable by
Middle Bay before expiration of the term if such termination is for cause (as
specified in the employment agreement). The executive employment agreements
provide for an annual salary of not less than the base salaries of $95,000 and
$85,000, respectively, which amounts may be adjusted from time to time by the
Board of Directors upon the recommendation of the Compensation Committee. They
also provide for fringe benefits in accordance with the Company's policies
adopted from time to time for salaried executive employees holding comparable
positions.

         Mr. Herod executed an employment agreement with Middle Bay with an
effective date of July 1, 1997 and extending through June 30, 1999, with
automatic one-year extensions upon each anniversary date of the employment
agreement thereafter unless either party gives at least 30 days' notice of
termination. The employment agreement is terminable by the Company before
expiration of the term if such termination is for cause (as specified in the
employment agreement). The executive employment agreement provides for an annual
salary of not less than the base salary of $100,000, which amount may be
adjusted from time to time by the Board of Directors upon the recommendation of
the Compensation Committee. It also provides for fringe benefits in accordance
with Middle Bay's policies adopted from time to time for salaried executive
employees holding comparable positions.

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

         Section 16(a) of the Securities Exchange Act of 1934 requires Middle
Bay's directors and executive officers and any persons who own more than 10% of
Middle Bay's common stock to file with the Securities and Exchange Commission
reports of ownership and changes in ownership of such securities. Based on
representations from such persons, Middle Bay believes that there was no failure
to file or delinquent filings under Section 16(a) of the Securities Exchange Act
of 1934 by any officer, director or beneficial owner of 10% or more of Middle
Bay's common stock during 1997.

<PAGE>   127
         Edward P. Turner, Jr., a director of Middle Bay, is managing partner of
the law firm of Turner, Onderdonk, Kimbrough & Howell, P.A., the Company's
general counsel for certain corporate and oil and gas matters. For the years
ended December 31, 1995 through 1997, Middle Bay paid legal fees to Mr. Turner's
firm of $787, $1,560 and $2,874, respectively, for legal services. Mr. Turner's
firm charges the Company for its services on the same basis as it charges other
business clients for similar services rendered. Middle Bay intends to continue
to use Mr. Turner's firm as its primary local counsel in Alabama and will pay
reasonable fees for such future services.

          Bay City Energy Group, Inc., is presently indebted to Middle Bay in
the amount of $166,165 ($139,005 of principal and $27,160 of accrued interest).
The note payable was renegotiated on December 31, 1995 and is due in full on
January 1, 2001, plus interest at an annual fixed rate of 5%. The note payable
is secured by 75,000 shares of Middle Bay's common stock. Edward P. Turner, Jr.,
a director of Middle Bay, has indirect voting control but not a beneficial
interest in Bay City Energy Group, Inc.

         On September 4, 1996, Middle Bay signed a stock purchase agreement with
Kaiser Francis Oil Company ("the Preferred Stock Agreement"). Kaiser-Francis
agreed to purchase 1,666,667 shares of Series A Preferred Stock ("Series A
Preferred") at $6.00 per share, for a total investment of $10,000,000. The
Series A Preferred is nonvoting and accrues dividends at 8% per annum, payable
quarterly in cash. The Series A Preferred is convertible at any time after
issuance into shares of common stock at the rate of two shares of common stock
for each share of Series A Preferred before January 1, 1998. The conversion rate
decreases thereafter at 8% per annum. On January 31, 1998, Kaiser-Francis
converted all 1,666,667 Series A Preferred shares it held into 3,333,334 shares
of Middle Bay's common stock. Prior to such conversion, Kaiser-Francis owned
none of the issued and outstanding common shares. Subsequent to the conversion,
Kaiser-Francis' shares represent 42.57% of the issued and outstanding shares of
common stock. Gary R. Christopher, a director of Middle Bay, serves as
Acquisitions Coordinator of Kaiser-Francis Oil Company.

         In December, 1996, Middle Bay entered into an Agreement and Plan of
Merger (the "NPC Merger") with NPC Energy Corporation ("NPC"). Pursuant to the
Merger, Middle Bay issued 562,000 shares of its common stock and paid $1,226,400
to certain of NPC's shareholders. Series A Preferred Stock in the amount of $1.0
million under the Preferred Stock Agreement was sold to finance the cash portion
of the purchase price.

         In February, 1997, Middle Bay entered into an Agreement and Plan of
Merger (the "Bison Merger") with Bison Energy Corporation ("Bison"), whereby
Bison was merged with a wholly-owned subsidiary of the Company in exchange
Middle Bay common stock and cash. Pursuant to the Bison Merger, Middle Bay
issued 1,167,556 shares of its common stock and net cash consideration of
$5,900,000 to C. J. Lett, III in exchange for all of the stock of Bison. 562,000
shares of Middle Bay common stock owned by Bison (as a result of the NPC Merger)
were canceled at closing. Mr. Lett became Executive Vice President of Middle Bay
on February 28, 1997 and is a director of the Company.

          On June 20, 1997, Middle Bay entered into an Agreement and Plan of
Merger (the "Shore Merger") with Shore Oil Company ("Shore"), whereby Shore was
merged with a wholly-owned subsidiary of Middle Bay in exchange for Middle Bay
common stock, Series B Preferred Stock (the "Series B Preferred"), cash


                                    - 115 -
<PAGE>   128
and the assumption of Shore debt. Shore was privately held principally by
Weskids, L.P. and Alvin V. Shoemaker. Shore's assets consist of oil and gas
properties located primarily in Alabama, Louisiana, Mississippi and Texas, as
well as approximately 42,000 net mineral acres in LaFourche, Terrebonne and St.
Mary Parishes, South Louisiana. Pursuant to the Shore Merger, Middle Bay issued
1,883,333 shares of its common stock, paid Shore's indebtedness to its
shareholders of $2,333,303 and assumed bank debt of $2,105,000. In addition,
Middle Bay paid $200,000 in cash and issued 266,667 shares of Series B Preferred
which are convertible into as many as 1,333,333 shares of common stock over the
next five years, contingent upon the results of drilling and leasing activity on
Shore's Louisiana mineral acreage. In connection with the merger, Messrs.
Shoemaker and Herod were appointed as directors, replacing Frank C. Turner and
C. Noell Rather. Mr. Herod was also appointed as Vice President - Corporate
Development.

31, 1996 and for the six months ended June 30, 1997. The amounts for the six
months ended December 31, 1997 are the result of the operations of the
Partnership.

          The Partnership is engaged in the oil and gas business through the
ownership of various interests in producing oil and gas properties, as detailed
below. If warranted, the Partnership may further develop its oil and gas
properties. However, the Partnership does not intend to engage in significant
drilling activities. Such activities may be conducted, however, as an incidental
part of the management of producing properties or with a view toward enhancing
the value of producing properties. In no event will the Partnership engage in
exploratory drilling, or use any of the limited partners' net revenues to fund
exploratory drilling activities. Any developmental drilling will be financed
primarily through third party borrowings or with funds provided from operations.
The expenses of drilling, completing and equipping and operating development
wells are allocated 96% to the limited partners and 4% to the general partner.
See Note 1 to the Financial Statements for information relating to the
allocation of costs and revenues between the limited partners and the general
partner, Enex Resources Corporation ("Enex"). The Partnership's operations are
concentrated in a single industry segment.


                                    - 116 -
<PAGE>   129
          The Partnership owns royalty interests in certain oil and gas
properties. A "royalty interest" is an interest retained by the lessor in the
lease and payable out of 100% of proceeds before deducting any other interests.
The Partnership also owns overriding royalty interests in certain oil and gas
properties. An "overriding royalty interest" is an interest in a property which
was carved out of the working interest that is not subject to most operating
costs associated with the property. The Partnership also owns working interests
in certain oil and gas properties. A "working interest" is a portion of the
operating interest which is subject to most of the costs associated with a well.

          The principal executive office of the Partnership is maintained at
1221 Lamar Street, Suite 1020, Houston, Texas 77010. The telephone number at
this office is (713) 759-6808. The Partnership has no regional offices.

          The Partnership has no employees. On September 30, 1998, Enex employed
six persons.

MARKETING

          The marketing of oil and gas produced by the Partnership is affected
by a number of factors which are beyond the Partnership's control, the exact
nature of which cannot be accurately predicted. These factors include the
quantity and price of crude oil imports, fluctuating supply and demand, pipeline
and other transportation facilities, the marketing of competitive fuels, state
and federal regulation of oil and gas production and distribution and other
matters affecting the availability of a ready market. All of these factors are
extremely volatile.

          Gulfmark Inc. accounted for 11% of the Partnership's total sales in
1997. No other purchaser individually accounted for more than 10% of such sales.

          The operators of the Partnership's major properties are noted below.
Although a significant portion of the Partnership's properties were operated by
a limited number of operators, this concentration does not pose a significant
risk since the Partnership's rights are secured by joint operating agreements.

ENVIRONMENTAL AND CONSERVATION REGULATION

          State regulatory authorities in the states in which the Partnership
owns producing properties are empowered to make and enforce regulations to
prevent waste of oil and gas and to protect correlative rights and opportunities
to produce oil and gas for owners of a common reservoir. Each of such regulatory
authorities also regulates the amount of oil and gas produced by assigning
allowable rates of production, which may be increased or decreased in accordance
with supply and demand. Requirements regarding the prevention and clean-up of
pollution and similar environmental matters are also generally applicable. The
costs, if any, the Partnership may incur in this regard cannot be predicted.

          The existence of such regulations has had no material adverse effects
on the Partnership's operations to date, and the cost of compliance has not yet
been material. There are no material administrative or judicial proceedings
arising under such laws or regulations pending against the Partnership. The
Partnership is


                                    - 117 -
<PAGE>   130
unable to assess or predict the impact that compliance with environmental and
pollution control laws and regulations may have on its future operations,
capital expenditures, earnings or competitive position.

TAX LAWS

          The operations of the Partnership are affected by the federal income
tax laws contained in the Internal Revenue Code of 1986, as amended (the
"Code"). Under the Code, generally, the Partnership will report income from the
sale of oil and gas, against which it may deduct its ordinary business expenses,
depletion, depreciation and intangible drilling and development costs.

          It is anticipated that most of the Partnership's income, if any, will
be from a "passive activity" for purposes of the Code. A passive activity
includes an activity in which the taxpayer does not materially participate,
including the ownership of a limited partnership interest such as an interest in
the Partnership. "Passive income," however, does not include portfolio income
(i.e. dividend, interest, royalties, etc.). Although taxpayers generally may not
deduct losses or use tax credits derived from passive activities in an amount
greater than their income derived from such activities, if and to the extent
that the Partnership generates passive income, it will be available to offset
the limited partners' passive losses from other sources.

          Partnerships with interests that are "publicly traded" are taxed as
corporations unless at least 90% of their income is "qualifying income." Passive
income or loss from publicly traded partnerships that are not taxed as
corporations generally cannot be applied against passive income or loss from
other sources. As stated in Item 5 of the Partnership's Annual Report, there is
no established public trading market for the Partnership's limited partnership
interests. In addition, the Partnership derives more than 90% of its income from
oil and gas activities, which constitutes qualifying income from oil and gas
activities, which constitutes qualifying income within the meaning of section
7704(d) of the Code. Therefore, the Partnership should not be affected by the
publicly traded partnership rules.

          In order to prevent the adverse tax consequences that would affect the
limited partners if the Partnership's limited partnership interests were to
become publicly traded in the future, the General Partner may, after final
regulations have been issued by the Internal Revenue Service, submit to a vote
of limited partners a proposal to amend the Partnership's Agreement of Limited
Partnership to provide, among other things, (a) that Enex shall have the right
to refuse to recognize any transfer of limited partnership interests if it
believes that such transfer occurred on a secondary market or the substantial
equivalent thereof; and (b) that all assignors and assignees of the limited
partnership interests shall be required to represent to Enex that any transfer
of limited partnership interests did not, to the best of their knowledge, occur
on a secondary market or the substantial equivalent thereof.

PROPERTIES

          On June 30, 1997, the Predecessor Partnerships transferred all of
their assets to the Partnership, subject to corresponding liabilities. These
properties continue to be operated by the Partnership as they were operated by
the Predecessor Partnerships. Presented below is a brief description of the
Partnership's major property holdings, all of which were transferred to it by
the Predecessor Partnerships.


                                    - 118 -

                  Concord. The Concord acquisition consists of working interest
and royalty interest in more than 10,600 wells in 137 counties in Texas, with
very minor interests in 12 other states.

                  H.N.G. The H.N.G. acquisition began with the purchase of
overriding royalty interests in over 300 gas wells in Texas, New Mexico, and
Oklahoma and culminated five transactions later with the last purchase of
overriding royalty interests in these properties. The H.N.G. acquisition is
operated by eight different oil and gas companies. The Partnership owns working
interests ranging from .104% to 8.999% in the H.N.G. acquisition at December 31,
1997.

                  East Seven Sisters. The East Seven Sisters acquisition was
comprised of six transactions in which parts of a mineral interest and the
associated royalty interest in the Gorman Gas Unit in the East Seven Sisters
Field, Duval County, Texas were acquired. The East Seven Sisters acquisition is
operated by Vastar Resources Inc. The Partnership owns a 9.81% royalty interest
in the East Seven Sisters acquisition at December 31, 1997.

          The Partnership has thirty additional acquisitions which were
transferred from the Predecessor Partnerships. In total, the Partnership has
interests in 11,118 oil well properties and 1,078 gas well properties which are
primarily located in Texas, Oklahoma and Louisiana.

OIL AND GAS RESERVES

          For quantitative information regarding the Partnership's oil and gas
reserves, please see Supplementary Oil and Gas Information and related tables
which follow the Notes to Financial Statements of Enex Consolidated Partners,
L.P. The Partnership has not filed any current oil and gas reserve estimates or
included any such estimates in reports to any federal or foreign governmental
authority or agency, including the Securities and Exchange Commission.

          Proved oil and gas reserves reported herein are based on engineering
reports prepared by the petroleum engineering consulting firm of H. J. Gruy and
Associates, Inc. The reserves included in this report are estimates only and
should not be construed as exact quantities. Future conditions may affect
recovery of estimated reserves and revenue, and all reserves may be subject to
revision as more performance data become available. The proved reserves used in
this report conform to the applicable definitions promulgated by the Securities
and Exchange Commission. No major discovery or other favorable or adverse event
that could potentially cause a significant change in the estimated proved
reserves has occurred since December 31, 1997.

NET OIL AND GAS PRODUCTION

          The following table shows for the years ended December 31, 1997 and
1996, the approximate production attributable to the Predecessor Partnerships'
and the Partnership's oil, gas, and gas plant product interests. The figures in
the table represent "net production," i.e., production owned by the Predecessor
Partnerships and the Partnership and produced to their interest after deducting
royalty and other similar interests. All production occurred in the United
States.

LEGAL PROCEEDINGS

         A Predecessor Partnership was named as a party to a suit filed by Texas
Crude, Inc. ("Texas Crude"). In the suit, Texas Crude sought to recover legal
and other fees totaling $600,000. In August 1993, a judgement was granted in
favor of Texas Crude for $414,203 plus interest by the 101st Judicial District
Court of Texas. The Partnership recognized a contingent liability at December
31, 1993 for $504,350.

         The Partnership appealed the verdict and filed a counterclaim for funds
that were wrongfully withheld by Texas Crude. In December 1994, the Fifth
District Court of Appeals reversed the judgement of the trial court and rendered
judgement in favor of the Partnership, in which the Partnership will recover
$163,019 from Texas Crude plus interest. Accordingly, the contingent liability,
initially recognized in 1993, was reversed in December 1994 and a receivable for
$254,588 was established in 1994.


                                    - 120 -
<PAGE>   133
         Both the Partnership and Texas Crude have filed Motions for Rehearing,
which have been pending for more than a year. The accrued receivable balance at
December 31, 1997 was $338,860.

         There are no other material pending legal proceedings to which the
Partnership is a party or to which any of their properties are subject.

DISTRIBUTIONS

         The Partnership and its Predecessor Partnerships made cash
distributions to limited partners of $4,593,955 and $2,464,947 in 1997 and 1996,
respectively, and through October, 1998, cash distributions have been
$3,068,166. This equated to $4.17 and $2.24 per Unit in 1997 and 1996,
respectively, and $2.78 per Unit in 1998 through October. The payment of future
distributions will depend on the Partnership's earnings, financial condition,
working capital requirements and other factors, although it is anticipated that
regular quarterly distributions will continue through 1998.


                                  LEGAL MATTERS

         The validity of the issuance of the securities to be issued pursuant to
the Exchange Offer will be passed upon for Middle Bay and certain federal income
tax matters relating to the Exchange Offer will be passed upon for Middle Bay by
Thrasher, Whitley, Hampton & Morgan, Atlanta, Georgia.


                   DESCRIPTION OF MIDDLE BAY EQUITY SECURITIES

         Middle Bay's Articles of Incorporation authorize 20,000,000 shares of
common stock, $0.02 par value per share, and 10,000,000 shares of preferred
stock, $0.02 par value per share.


                                    - 121 -
<PAGE>   134
COMMON STOCK

         As of September 30, 1998, there were 8,530,592 shares of common stock
outstanding, held by approximately 1,000 registered holders.

         In all matters to come before the shareholders, holders of common stock
have one vote per share. Holders of common stock are not entitled to cumulative
votes, which means that the holders of a majority of the total voting power of
such shares can elect all of the directors entitled to be elected by the holders
of common stock. In the event of liquidation of the Company, the holders of
common stock are entitled to receive, on a pro-rata basis, all of the assets
then legally available for distribution, subject to any preferential rights of
the holders of preferred stock.

         The holders of common stock are entitled to dividends and other
distributions as and when declared by the Board of Directors out of assets
legally available therefor, subject to any preferential dividend rights of the
holders of any preferred stock which may be outstanding or issued in the future
or any credit agreements or other contracts restricting payment of dividends.
The shares of common stock are not subject to redemption, and the holders of the
common stock have no preemptive or subscription rights. The issued and
outstanding shares of common stock are fully paid and nonassessable.

PREFERRED STOCK

         As of September 30, 1998, there were 266,667 shares of preferred stock
which have been designated Series B Preferred by the Board of Directors, of
which 266,667 shares were issued in connection with the Shore Merger (see
"Certain Relationships and Related Transactions") and are presently outstanding;
and there are 2,300,000 shares of preferred stock which have been designated as
Series C Preferred, none of which are presently issued and outstanding, but
which are expected to be issued in connection with the Exchange. The 1,666,667
Series A Preferred shares which were issued and outstanding in 1997 were
converted into 3,333,334 shares of common stock of Middle Bay on January 31,
1998 (see "Certain Relationships and Related Transactions"). The Series B
Preferred shares are nonvoting but are convertible into as many as 1,333,333
shares of common stock, contingent upon the results of drilling and leasing
activity on mineral acreage in South Louisiana acquired in the Shore Merger.
Additional shares of authorized preferred stock may be issued from time to time
by the Board of Directors in one or more series, with each series having such
designation rights (including voting rights or the absence thereof) and
preferences as may be determined by the directors.

         The Series C Preferred is generally nonvoting; however, holders of
Series C Preferred are entitled to a vote on any amendment, alteration or repeal
of any provisions of Middle Bay's Articles of Incorporation adversely affecting
their rights and preferences as preferred stockholders; provided, however, that
the issuance by Middle Bay of additional series of preferred stock will not be
deemed to adversely affect the rights and preferences of the holders of Series C
Preferred, so long as any such series of preferred stock ranks junior to or on a
parity with the Series C Preferred. The Middle Bay Articles of Incorporation
provide that, so long as any shares of Series C Preferred are outstanding,
Middle Bay shall not issue any class or series of stock which would entitle the
holders thereof to the receipt of dividends or of amounts distributable upon


                                    - 122 -
<PAGE>   135
liquidation, dissolution or winding up, as the case may be, in preference or
priority to the holders of Series C Preferred shares. The Series B Preferred
shares rank in parity with the Series C Preferred shares with regard to
preferences upon liquidation, dissolution or winding up of Middle Bay.

         At any time from and after the Effective Date, the holders of Series C
Preferred shares will have the right to convert each share of Series C Preferred
into one share of Middle Bay common stock (as such conversion rate may be
adjusted as a result of any dividend, subdivision or combination of Middle Bay
common stock).

         The holders of Series C Preferred shares are also entitled to receive
cumulative cash dividends in an amount per share of $.50 per annum, payable
semi-annually on March 31st and September 30th of each year (measured by the
fiscal year of Middle Bay). No dividends may be authorized or paid or set apart
for payment or other distribution of cash or other property authorized or made
directly or indirectly by Middle Bay with respect to any shares of Middle Bay
common stock or other junior securities of Middle Bay unless the full cumulative
dividends on all outstanding shares of Series C Preferred shall have been paid
or such dividends have been authorized and set apart for payment with respect to
the Series C Preferred shares.

         Prior to January 1, 2000, shares of Series C Preferred will not be
subject to redemption by Middle Bay. On and after January 1, 2000, Middle Bay
may redeem all or a portion of the Series C Preferred, at its option, at a
purchase price of $5.00 per share, plus an amount equal to all accumulated,
accrued and unpaid dividends, if any, to the date of redemption, subject to the
holders' rights to convert. If Middle Bay elects to redeem all or a portion of
the shares of Series C Preferred, it is required by the Articles of
Incorporation to select the date on which such redemption will occur (the "Call
Date") and must give notice to all holders of Series C Preferred shares of
record not less than 30 days nor more than 60 days prior to the Call Date of (a)
the Call Date, (b) the number of shares to be redeemed and, if fewer than all
shares held by such holder are to be redeemed, the pro-rata number of shares to
be redeemed from such holder, (c) the place or places at which certificates for
such shares are to be surrendered for certificates representing shares of Middle
Bay common stock, (d) the then-current conversion rate, and (e) the fact that
dividends on the shares of Series C Preferred to be redeemed will cease to
accrue on the Call Date (except as otherwise provided in the Articles of
Incorporation). The Call Date may not be less than 30 days nor more than 60 days
after the date such notice of redemption is sent by Middle Bay. If fewer than
all the outstanding shares of Series C Preferred are to be redeemed on any Call
Date, shares to be redeemed will be selected by Middle Bay (i) by lot, (ii) pro
rata or (iii) by any other method as may be determined by the Board of Directors
in its discretion to be equitable. A notice of redemption will be sent by first
class mail to the address of each holder of Series C Preferred shares, as the
same appears on the stock records of Middle Bay, and may, in conjunction with
such mailing, be published in The Wall Street Journal or the Houston, Texas
Chronicle. Subject to applicable escheat laws, any cash set aside by Middle Bay
to so redeem shares of Series C Preferred that is unclaimed at the end of two
years from the Call Date will revert to the general funds of Middle Bay, after
which time the holders of shares called for redemption will be entitled to
payment of such cash only from the general funds of Middle Bay.

         In the event of a liquidation, dissolution or winding up of Middle Bay,
holders of Series C Preferred shares will have the right to liquidation
preferences in the amount of $5.00 per share held, plus an amount


                                    - 123 -
<PAGE>   136
equal to all dividends accumulated, accrued and unpaid thereon to the date of
final distributions to such holders, before any payment will be made to holders
of Middle Bay common stock or other junior securities of Middle Bay. The
liquidation preferences of the Series C Preferred shares rank on a parity with
the presently issued and outstanding Series B Preferred shares.

         The shares of Series C Preferred to be issued in connection with the
Middle Bay Exchange Offer and all shares of Middle Bay common stock issuable
upon conversion of the Series C Preferred, when so issued, will be fully paid
and nonassessable.

         Application has been made by Middle Bay requesting that the Series C
Preferred shares be approved for listing on the NASDAQ Small Cap Stock Market,
subject to official notification of issuance.

CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK

         As of September 30, 1998, there are 11,447,636 unissued shares of
common stock and 9,733,333 shares of preferred stock authorized under Middle
Bay's Articles of Incorporation for future issuance without shareholder
approval. 1,500,000 of these additional shares of common stock have been
reserved for possible exercise of stock options described under "Compensation
Under Plans," and 2,300,000 shares have been reserved for the possible
conversion of the Series C Preferred shares issuable pursuant to the Exchange.
The remaining additional shares of common or preferred stock may be used for a
variety of corporate purposes, including possible future public or private
offerings to raise additional capital, to facilitate corporate acquisitions or
for executive incentive compensation.

         One of the effects of the existence of unissued and unreserved common
stock and preferred stock may be to enable the Board of Directors to issue
shares to persons friendly to current management, which could render more
difficult or discourage an attempt to obtain control of Middle Bay by means of a
merger, tender offer, proxy contest or otherwise, and thereby protect the
continuity of Middle Bay's management. Such additional shares also could be used
to dilute the stock ownership of persons seeking to obtain control of Middle
Bay.

         The Board of Directors is authorized, without any action by the
shareholders, to determine the rights, preferences, privileges and restrictions
of the unissued preferred stock. The purpose of authorizing the Board of
Directors to determine such rights and preferences is to eliminate delays
associated with a shareholder vote on specific issuances. The Board of Directors
may issue preferred stock with voting and conversion rights which could
adversely affect the voting power of the holders of Middle Bay common stock and
which could, among other things, have the effect of delaying, deferring or
preventing a change in control of Middle Bay.

         Management of Middle Bay does not have any current plans to issue
additional shares of common or preferred stock, other than the shares of Series
C Preferred which would be issuable in connection with the Exchange.

            INDEMNIFICATION OF MIDDLE BAYS DIRECTORS AND OFFICERS

      The Alabama Business Corporation Act provides in Section 10-2A-75,
generally, that a director shall perform his duties as a director in good faith,
in a manner he reasonably believes to be in the best interests of the
corporation, and with such care as an ordinarily prudent person in a like
position would use under similar circumstances.

      Middle Bay's Articles of Incorporation provide that the corporation shall
indemnify each director, as well as each officer, employee or agent, to the
fullest extent permitted by Alabama law. Section 10-2A-21 of the Alabama
Business Corporation Code provides for full indemnification against liability,
including attorney's fees and costs, for such persons so long as the person
acted in good faith reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. The
Articles of Incorporation empower Middle Bay to purchase and maintain insurance
for its officers, directors, employees and agents to insure against liabilities
asserted against or incurred by any of them in such capacities arising out of
one's status as such, but no such insurance has been provided by Middle Bay and
none is presently contemplated.

                          Independent Auditors' Report

Board of Directors and Stockholders
Middle Bay Oil Company, Inc.

         We have audited the accompanying consolidated balance sheets of Middle
Bay Oil Company, Inc. and subsidiaries as of December 31, 1997 and 1996, and the
related statements of operations, changes in stockholders' equity and cash flows
for the years then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Middle Bay
Oil Company, Inc. and subsidiaries at December 31, 1997 and 1996, and the
results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

         As discussed in Note 1 to the financial statements, the Company
restated its consolidated financial statements to exclude a valuation allowance
in presenting its net deferred income tax liability.

                          MIDDLE BAY OIL COMPANY, INC,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1996

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICES

Organization

         Middle Bay Oil Company, Inc. (the Company), was incorporated under the
laws of the state of Alabama on November 20, 1992. On December 31, 1996, the
Company acquired NPC Energy Corporation, and during 1997, the Company acquired
Bison Energy Corporation and Shore Oil Company (See Note 2). The Company is
engaged in the acquisition, development and production of oil and natural gas in
the contiguous United States.

Significant Accounting Policies

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

Principles of Consolidation

         The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries. All significant intercompany balances
and transactions have been eliminated in consolidation.

Restatement of the 1997 Financial Statements

         In 1998, the Company restated its 1997 financial statements to
correctly state deferred income taxes for improper inclusion of a valuation
allowance for deferred income taxes. This restatement resulted in an adjustment
decreasing the net loss and net loss available to stockholders by $1,125,542.
The net loss per share decreased $.34 as a result of the restatement.

Cash and Cash Equivalents

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

Oil and Gas Property

         The Company follows the successful efforts method of accounting for oil
and gas properties, and accordingly, capitalizes ad direct costs incurred in
connection with the acquisition, drilling and development of productive oil and
gas properties. Costs associated with unsuccessful exploration are charged to
expense currently. Geological and geophysical costs and costs of carrying and
retaining unevaluated properties are charged to expense. Depletion,

                                      F-9


<PAGE>   157



depreciation and amortization of capitalized costs are computed separately for
each property based on the unit of production method using only proved oil and
gas reserves. In arriving at such rates, commercially recoverable reserves have
been estimated by independent petroleum engineering firms. The Company reviews
its undeveloped properties continually and charges them to expense on a property
by property basis when it is determined that they have been condemned by dry
holes, or will not be retained, sold or drilled upon.

Site Restoration, Dismantlement and Abandonment Costs

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

         The Company, in conjunction with its independent engineers and the
operators of the wells, continually reviews its working interests with respect
to potential P&A costs. When conditions require that a well be plugged and
abandoned, the appropriate accounting procedures are followed. When a well, or
the last well of a group of proved properties ceases to produce or is no longer
economically feasible to produce, the entire cost related to the well or group
of wells, which includes estimated future dismantlement and abandonment cost, is
written off and gain or loss is recognized. Any additional liabilities arising
from P&A costs, net of salvage value of the equipment, are accrued in the
financial statements and charged to expense in the current period.

         P&A costs are considered in the proved oil and gas reserve estimates as
disclosed in Note 11 - Supplemental Oil and Gas Reserve Information; and, if
material, the present value of the reserves is reduced accordingly.

         As of December 31, 1997 and 1996, the P&A costs accrued were
immaterial.

Impairment of Long Lived Assets

         Statement of Financial Accounting Standards No. 121 "Accounting for the
Impairment of Long Lived Assets and for Long Lived Assets to be disposed of"
(SFAS No. 121) was issued in March 1995. This statement requires that long lived
assets be reviewed for impairment when events or changes in circumstances
indicate that the carrying value of such an asset may not be recoverable. This
review consists of a comparison of the carrying value of the asset to the
asset's expected future undiscounted cash flows without interest costs.

         Estimates of expected future cash flows represent management's best
estimate based on reasonable and supportable assumptions and projections. If the
expected future cash flows are less than the carrying value of the asset, an
impairment exists and is measured as the excess of the carrying value over the
estimated fair value of the asset. Any impairment provisions recognized in
accordance with SPAS No. 121 are permanent and may not be restored in the
future.

                                     F-10


<PAGE>   158

         In the fourth quarter of 1997 and 1996 the Company's proved properties
were assessed for impairment on an individual field basis and the Company
recorded impairment provisions of $21,147,823 and $277,483 respectively,
attributable to certain producing properties.

         Prior to the adoption of SFAS No. 121, the Company assessed its proved
oil and gas properties on an individual field basis using management's best
estimate of the expected future cash flows from the producing properties.

Other Property and Equipment

         Property and equipment are stated at cost and depreciation is computed
on the accelerated method over appropriate lives ranging from five to seven
years. Additions and betterments which provide benefits to several periods are
capitalized.

Environmental Liabilities

         Environmental expenditures that relate to current or future revenues
are expensed or capitalized as appropriate. Expenditures that relate to an
existing condition caused by past operations, and do not contribute to current
or future revenue generation, are expensed. Liabilities are recorded when
environmental assessments and/or clean-ups are probable, and the costs can be
reasonably estimated. Generally, the timing of these accruals coincides with the
Company's commitment to a formal plan of action.

Revenue

         Oil and gas revenues are recorded using the sales method, whereby the
Company recognizes revenues based on the amount of oil and gas sold to
purchasers on its behalf.

Income Taxes

         The Company uses the asset and liability method of accounting for
income taxes required by the Statement of Financial Accounting Standards No.
109. Under the asset and liability method, deferred tax assets and liabilities
are determined by applying enacted statutory tax rates applicable to future
years to the difference between the financial statement and tax basis of assets
and liabilities.

Stock Based Compensation

         In October 1995, The Financial Accounting Standards Board ("FASB")
issued SFAS No. 123, "Accounting for Stock Based Compensation", which
establishes financial accounting and reporting standards for stock based
compensation plans. Effective for fiscal years beginning after December 31,
1995, the statement provides the option to continue under the accounting
provisions of APB No. 25, while requiring proforma footnote disclosures of the
effects of net income and earnings per share, calculated as if the new method
had been implemented. The Company has adopted the financial reporting provisions
of SFAS No. 123 for 1997, but will continue under the accounting provisions of
APB Opinion 25.

Use of Estimates

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

Earnings Per Share

         Effective December 31, 1997, the Company adopted SFAS No. 128,
"Earnings per Share." This statement establishes standards for computing and
presenting earnings per share, and requires, among other things, dual
presentation of basic and diluted earnings per share on the face of the
statement of operations. In accordance with SFAS No. 128, earnings per share and
weighted average shares outstanding have been restated to conform to this
statement for all periods presented.

Concentrations of Market Risk

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

Concentrations of Credit Risk

         Financial instruments which subject the Company to concentrations of
credit risk consist primarily of cash and accounts receivable. The Company
places its cash investments with high credit qualified financial institutions.
Risk with respect to receivables is concentrated primarily in the current
production revenue receivable from multiple oil and gas producers, both major
and independent, and is typical in the industry. The Company sold oil and gas
representing approximately 14% of its total production to one customer, Warren
Petroleum, for the year ended December 31, 1997.

Accounting Pronouncements

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 130, "Reporting Comprehensive Income." This statement establishes
standards for reporting and display of comprehensive income and its components
in the Company's financial statements. Comprehensive income includes all changes
in the Company's equity except investments by and distributions to owners and
includes, among other things, foreign currency translation adjustments. In June
1997, the FASB also issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." This statement establishes standards for
reporting information about operating segments in annual financial statements
and requires selected information about operating segments be included in
interim reports issued to shareholders. Both of these statements are effective
for financial statements for periods beginning after


                                      F-12


<PAGE>   160



December 15, 1997. As both SFAS Nos. 130 and 131 establish standards for
reporting and display, the Company does not expect the adoption of these
statements to have a material impact on its financial condition or results of
operations.

(2) ACQUISITIONS

         On December 31, 1996, the Company completed the acquisition of NPC
Energy Corporation ("NPC"). The transaction consisted of a merger (the "NPC
Merger") of NPC into the Company and its separate corporate existence ceased.

         The cost of acquiring NPC was approximately $3.20 million, consisting
of the following (in thousands):

         On April 3, 1996, the Bank concerted its $5.6 million term note into a
$6.0 million, one-year, revolving line-of-credit (the "$6 million Convertible
Loan"), effective April 1, 1996. The $6 million Convertible Loan required
monthly payments of interest only at prime plus 1.5% and converted into a term
note payable in seventy-one consecutive equal monthly principal and interest
payments at prime plus 1.5%, with the remaining principal and interest payment
due on March 31, 2003. Effective March 31, 1997, the Company refinanced the $6
million Convertible Loan at its current principal balance of $5,186,596 with a
$15 million Convertible Loan. The $15 million Convertible Loan required monthly
payments of interest only at prime for one year and converts into a term note
payable in seventy-one consecutive equal monthly principal and interest payments
at prime, with the remaining principal and interest payment due on March
31, 2004. The $15 million Convertible Loan also required payment of a commitment
fee equal to an annual rate of three-eighths percent of the excess of the
Borrowing Base over the

                                      F-16

principal balance of the convertible note. Effective August 25, 1997, the
Company refinanced the $15 million Convertible Loan at its current principal
balance of $5,851,298 with a $50 million Convertible Loan. The $50 million
Convertible Loan requires monthly payments of interest only at a fixed rate of
Libor plus 1.75% as long as the principal amount of the loan is less than 75% of
the current borrowing base of $15 million. If the principal amount of the loan
is greater than or equal to 75% of the borrowing base the rate increases to
Libor plus 2.00%. The Company has the option of switching to a floating prime
rate. The $50 million Convertible Loan converts into a term note payable in
seventy-one consecutive equal monthly principal and interest payments at prime,
with the remaining principal and interest payment due on March 31, 2004. The $50
million Convertible Loan also requires payment of a commitment fee equal to an
annual rate of three-eighths percent of the excess of the Borrowing Base over
the principal balance of the convertible note. The principal balance of the $50
million Convertible Loan at December 31, 1997 was $10,956,298.

         The initial borrowing base of the $50 million Convertible Loan at
closing on August 25, 1997, was $15 million. The borrowing base will be
redetermined on March 31 and September 30, commencing September 30, 1997, by the
Bank's engineers or any other independent engineer using the Bank's pricing and
discount factors and the future net revenue expected to be produced from the
Company's oil and gas reserves. If at any time during the period of the
Convertible Loan (and the period subsequent to the conversion to the term note)
the collateral borrowing base, as determined by the Bank, should be less than
the aggregate unpaid principal balance of the note, the collateral deficiency
shall be cured by making a cash prepayment on the note in the amount of the
deficiency or by increasing the monthly principal payments for the next six
months to reduce the principal balance to the projected borrowing base as of the
next semiannual redetermination date.

         The $50,000,000 convertible loan contains certain restrictive
provisions the most significant of which restricts additional borrowings, either
directly or indirectly, and payment of dividends. At December 31, 1997, the
Company was in compliance with all covenants specified in the agreement.

         Aggregate amounts of expected required repayments of long term debt at
December 31, 1997 are as follows:

         All of the employees of the Company participate in a defined
contribution plan which provides for a maximum discretionary Company
contribution of 15% of total wages paid to employees for the year. The Company
contributed $51,560 and $5,000 to the plans for the years ended December 31,

(7) STOCK OPTION AND STOCK APPRECIATION RIGHTS PLAN

         At December 31, 1997, the Company had one fixed stock option plan, the
1995 Stock Option and Stock Appreciation Rights Plan (1995 Plan). The Company
applies APB Opinion 25, "Accounting for Stock Issued to Employees" and related
interpretations in accounting for the plan; accordingly, no compensation cost
has been recognized. Had compensation cost for the Company's 1995 Plan been
determined based on the fair value at the grant date for stock options granted
during 1997 and 1996 consistent with the method of FASB Statement 123,
"Accounting for Stock Based Compensation"' the Company's net income and earnings

         The fair value of each option is estimated on the date of grant using
the Black-Scholes option-pricing model with the following assumptions used for
the grants in 1997 and 1996; no dividend yield; expected volatility of 60
percent and 50 percent, respectively; risk-free interest rate of 6.06% and
6.38%, respectively; and expected life of 3 years. At December 31, 1997, the
range of exercise prices and weighted average remaining contractual life of
options outstanding was $2.50 and $7.00 and 9.06 years, respectively.

The 1995 Plan

         At December 31, 1997 there were 80,000 shares of common stock available
for grant under the 1995 plan. All of the options granted under the 1995 Plan
have an exercise price equal to the fair market value of the Company's common
stock at the date of the grant and expire ten (10) years from the date of grant
if not exercised. All of the options granted under the 1995 Plan are 100% vested
The 1995 Plan is administered by the Compensation Committee of the Board of
Directors.

         Options to acquire 225,000 shares of the Company common stock at an

(8) CAPITAL STOCK

Preferred Stock

         In connection with the merger with Shore Oil Company, effective June
30, 1997, the Company issued 266,667 shares of Series B Preferred Stock ("Series
B"). The Series B is nonvoting and pays no dividends. The Series B has a
liquidation value of $7.50 per share and is junior to the Series A Preferred.
For a period of sixty-six months subsequent to June 30, 1997 any holder of the
Series B may convert all or any portion of Series B shares into Company Common
Stock ("Common") at a ratio of one share of Common for each Series B share or at
any time on or after January 1, 1998, the holders may convert their Series B
Preferred shares based on a conversion method whereby the number of convertible
Series B Preferred shares is calculated as the increase in value of
approximately 40,000 acres of mineral interest owned by Shore at the end of the
year divided by $8,000,000 and multiplied by 266,667 shares. Each of the
convertible Series B Preferred shares is then multiplied by 1,066,000 to arrive
at the potential converted number of common shares. Upon expiration of the
conversion period, unless the Company has given notice to redeem the Series B,
all of the shares of Series B shall be automatically converted. In no event
shall the aggregate total number of shares of Common into which the Series B are
converted be less than 266,667 shares or exceed 1,333,333 shares, unless further
increased for any anti-dilution provisions.

         On September 4, 1996, the Company signed a stock purchase agreement
with Kaiser Francis Oil Company ("the Agreement"). Kaiser-Francis has agreed to
purchase 1,666,667 shares of Series A Preferred Stock ("Series A") at $6.00 per
share, for a total investment of $10,000,000. The parties agreed to a five-year
purchase period, effective September 4, 1996, with minimum incremental
investments of $500,000 each. Each issuance of Series A is subject to approval
by Kaiser-Francis of the use of proceeds. The Series A is nonvoting and accrues
dividends at 8% per annum, payable quarterly in cash. The Series A is
convertible at any time after issuance into shares of common stock at the rate
of two shares of common stock for each share of Series A before January 1, 1998.
The conversion rate



                                      F-20
<PAGE>   168


decreases thereafter at 8% per annum. The Company will pay the costs of
registration of the Series A or the underlying common stock upon request of
Kaiser-Francis. The Company may redeem the Series A in whole or in part, at any
time after January 1, 2007 at a price of $6.00 per share. As of December 31,
1997, 1,666,667 shares of the Series A had been issued.

Common Stock

         On April 1, 1996, the Board of Directors authorized the repurchase of
up to $100,000 of Company common stock at a price per share not to exceed $3.25,
exclusive of brokerage costs. As of December 31, 1997 the Company had purchased
21,773 shares of common stock at a cost of $68,040.

         Under the terms of the Janex Acquisition in 1993, the Company had a
contingent obligation to repurchase 142,107 common shares issued in the Janex
Acquisition, upon written notice delivered to the Company, beginning five years
after the closing date and continuing for thirty days thereafter, at a price of
$6.00 per share. This obligation will terminate if the Comparers stock trades at
a share price of $8.00 or greater for twenty consecutive trading days during the
thirty-six month period ending November 1, 1998. At the close of trading on
April 7, 1997, the Company's common stock had traded at an ask price that was
equal to, or exceeded, $8.00 per share for twenty consecutive trading days.
Therefore, the contingent obligation represented by the redeemable common stock
balance on the Company's balance sheet in the amount of $421,179 was
reclassified to additional paid-in capital effective April 7, 1997.

         On February 13, 1997, the Company awarded the President,
Vice-President/Chief Financial Officer and Vice-President of Engineering stock
options to acquire 100,000, 62,500 and 62,500 shares of common stock,
respectively, at an exercise price of $5.50 per share. All of the options vested
on the date of grant. The exercise price was equal to the fair market value of
common stock on the date of grant. On the same date, The Company awarded to the
President, Vice-President/Chief Financial Officer and Vice-President of
Engineering, 25,909, 11,591 and 11,591 shares of restricted stock of the
Company, respectively. The restricted stock awards are contingent on the
performance of services to the Company in the future with 50% of the restricted
shares being earned over the six month period July, 1997 to December 31, 1997
and 50% over the six month period January 1, 1998 to June 30, 1998. As of
December 31, 1997, 50% of the restricted stock awards had been earned.

         On May 30, 1997, the Board of Directors granted options to acquire
85,000 shares of Company common stock under the 1995 Stock Option and Stock
Appreciation Rights Plan to certain key employees. All of the options vested on
the grant date of May 30, 1997 with an exercise price of $7.75 per share, which
was equal to the fair market value of common stock on the date of grant. The
options expire ten years from the date of grant if not exercised.

         On February 6, 1997, the Board of Directors granted options to acquire
210,000 shares of Company common stock under the 1995 Stock Option and Stock
Appreciation Rights Plan to key employees and non-employee directors. All of the
options vested on the grant date of February 6, 1997 with an exercise price of
$6.00 per share, which was equal to the fair market value of common stock on the
date of grant. The options expire ten years from the date of grant if not
exercised.

         On May 31, 1996, the Board of Directors granted options to acquire
125,000 shares of Company common stock under the 1995 Stock Option and Stock
Appreciation Rights Plan to key employees and non-employee directors.

ESTIMATED QUANTITIES OF RESERVES (UNAUDITED)

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

         The Company retains independent engineering firms to provide annual
year end estimates of the Company's future net recoverable oil, gas and natural
gas liquids reserves. The information for 1997 is based upon estimates prepared
by Lee Keeling and Associates, Inc., Cawley, Gillespie and Associates, Inc.,
Ryder Scott Company, Huddleston & Company, Inc., and DeGoyler & MacNaughton,
which were engaged to perform an evaluation of the Company's oil and gas
reserves. The information for 1996 was prepared by Lee Keeling and Associates,
Inc. and Cawley, Gillespie and Associates, Inc. The reserve information was
prepared in accordance with guidelines established by the Securities and
Exchange Commission. Estimated proved net recoverable reserves as shown below
include only those quantities that can be expected to be commercially
recoverable at prices and costs in effect at the balance sheet dates under
existing regulatory practices and with conventional equipment and operating
methods. Proved developed reserves represent only those reserves expected to be
recovered through existing wells. Proved undeveloped reserves include those
reserves expected to be recovered from new wells or on undrilled acreage or from
existing wells on which a relatively major expenditure is required for
recompletion.

         Net quantities of proved developed and undeveloped reserves of natural
gas and crude oil, including condensate and natural gas liquids, are summarized
as follows:

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS FROM PROVED RESERVES
(UNAUDITED)

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

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

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

         During recent years, there have been significant fluctuations in the
prices paid for crude oil in the world markets. The situation has had a
destabilizing effect on the crude oil posted prices in the United States,
including the posted prices paid by purchasers of the Company's crude oil. The
year end prices of oil and gas at December 31, 1997 and 1996, used in the above
table were $16.18 and $24.50 per barrel of oil and $2.54 and $3.70 per thousand
cubic feet of gas, respectively.

                   Notes to Consolidated Financial Statements

                               September 30, 1998
                                   (Unaudited)

   (1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 
   
     ORGANIZATION

        Middle Bay Oil Company, Inc., was incorporated under the laws of the
   State of Alabama on November 30, 1992. Effective March 27, 1998, the Company
   acquired 79.2% of Enex Resources Corporation and effective April 16, 1998,
   the Company acquired the assets of Service Drilling Co., LLC. In 1997, the
   Company acquired Bison Energy Corporation and Shore Oil Company. The Company
   and its subsidiaries are engaged in the acquisition, development and
   production of oil and gas in the contiguous United States.

     BASIS OF PRESENTATION

        In management's opinion, the accompanying consolidated financial
   statements contain all adjustments (consisting solely of normal recurring
   adjustments) necessary to present fairly the consolidated financial position
   of the Company as of September 30, 1998 and December 31, 1997 and the
   consolidated results of operations and consolidated cash flows for the
   periods ended September 30, 1998 and 1997.

        An independent accountant has not audited the accompanying consolidated
   financial statements. Certain information and disclosures normally included
   in annual audited financial statements prepared in accordance with generally
   accepted accounting principles have been omitted, although the Company
   believes that the disclosures made are adequate to make the information
   presented not misleading. These consolidated financial statements should be
   read in conjunction with the Company's financial statements and notes thereto
   included in the Company's Annual Report on Form 10-KSB/A for the year ended
   December 31, 1997.

        Certain reclassifications have been made to conform with the current
   presentation.

     SIGNIFICANT ACCOUNTING POLICIES

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

     Principles of Consolidation

        The consolidated financial statements include the accounts of the
   Company and its wholly-owned subsidiary, Middle Bay Production Company
   (formerly Bison Production Company), Enex Resources Corporation (Enex), a
   79.20% owned subsidiary and Enex Consolidated Partners, L.P. (Enex
   Partnership), a limited partnership of which Enex owns greater than a 50%
   interest. The equity of minority interests in Enex and the Enex Partnership
   is shown in the consolidated statements as "minority interest". Significant
   intercompany accounts and transactions are eliminated in consolidation.

   (1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

     Use of Estimates

        Management has made a number of estimates and assumptions relating to
   the reporting of assets and liabilities to prepare the financial statements.
   Actual results could differ from those estimates.

     Statements of Cash Flows

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

     Oil and Gas Properties

        The Company follows the "successful efforts" method of accounting for
   its oil and gas properties, and accordingly, capitalizes all direct costs
   incurred in connection with the acquisition, drilling, and development of
   productive oil and gas properties. Costs associated with unsuccessful
   exploration are charged to expense currently. Geological and geophysical
   costs and costs of carrying and retaining unevaluated properties are charged
   to expense. Depletion, depreciation and amortization of capitalized costs are
   computed separately for each property based on the unit-of-production method
   using only proved oil and gas reserves. In arriving at such rates,
   commercially recoverable reserves have been estimated by independent
   petroleum engineering firms. The Company reviews its undeveloped properties
   quarterly and charges them to expense on a property by property basis when it
   is determined that they have been condemned by dry holes, or will not be
   retained, sold or drilled upon.

     Site Restoration, Dismantlement & Abandonment Costs

        Site restoration, dismantlement and abandonment costs (P&A costs)
   include costs associated with dismantling and disposing of the facilities and
   equipment required to operate a well and restoring the well site to specified
   conditions. The Company develops specific estimates of its P&A costs based on
   consultations with its engineers and reevaluates such estimates quarterly.
   Estimated future P&A costs are accrued on a unit-of-production method based
   on proved reserves. As of September 30, 1998 approximately $485,000 of P&A
   costs has been accrued. The P&A costs accrued at December 31, 1997 were
   immaterial.

   (1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

     Impairment of Long-Lived Assets

        Statement of Financial Accounting Standards No. 121 "Accounting for the
   Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of"
   (SFAS No. 121) was issued in March 1995 and was adopted by the Company in the
   fourth quarter of 1997. This statement requires that long-lived assets be
   reviewed on a quarterly basis for impairment when events or changes in
   circumstances indicate that the carrying value of such assets may not be
   recoverable. This review consists of a comparison of the carrying value of
   the asset with the asset's expected future undiscounted cash flows without
   interest costs.

        Estimates of expected future cash flows represent management's best
   estimate based on reasonable and supportable assumptions and projections. If
   the expected future cash flows are less than the carrying value of the asset,
   an impairment exists and is measured as the excess of the carrying value over
   the estimated fair value of the asset. Any impairment provisions recognized
   in accordance with SFAS No. 121 are permanent and may not be restored in the
   future.

        The impairment expense in the current period of $492,000 was due to an
   unsuccessful recompletion attempt on the Goldberg #2 well in the Abbeville
   Field located in Vermillion Parish, Louisiana. The reserves had been
   classified as proved behind pipe.

     Other Property and Equipment

        Other property and equipment are stated at cost and depreciation is
   computed over appropriate lives ranging from five to seven years. Additions
   and betterments, which provide benefits to several periods, are capitalized.

     Income Taxes

        The Company uses the asset and liability method of accounting for income
   taxes. Under the asset and liability method, deferred tax assets and
   liabilities are determined by applying enacted statutory tax rates applicable
   to future years to the difference between the financial statement and tax
   basis of assets and liabilities.

   (1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (concluded)
 
     Earnings Per Share

        Effective December 31, 1997, the Company adopted SFAS No. 128, "Earnings
   Per Share." This statement establishes standards for computing and presenting
   earnings per share, and requires, among other things, dual presentations of
   basic and diluted earnings per share on the face of the statement of
   operations. In accordance with SFAS No. 128, earnings per share and weighted
   average shares outstanding have been restated to conform to this statement
   for all periods presented. A weighted average of 330,297 and 288,535 common
   stock equivalents are not considered in the 1998 calculation of diluted
   earnings per share for the nine month and three month periods ending
   September 30, respectively, due to the net loss recorded during these
   periods.

     Concentrations of Market Risk

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

   (2)  ACQUISITIONS

        On February 28, 1997, the Company completed the acquisition of Bison
   Energy Corporation ("BEC"). The transaction consisted of a merger (the "Bison
   Merger") of BEC into Bison Energy Corporation-Alabama, a wholly-owned
   subsidiary of the Company. On February 28, 1997, Bison Energy
   Corporation-Alabama merged into BEC and its separate corporate existence
   ceased. BEC was merged into the Company on January 1, 1998.
 
        The cost of acquiring BEC was approximately $10 million, consisting of
   the following (in thousands):

</TABLE>

        The fair value of the securities issued in connection with the merger
   was calculated using the price of the Company's common stock at the time the
   Bison Merger was announced to the public of $5.50 per share.

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

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

        The price paid for BEC and the allocation of the purchase price, both
   detailed above, excludes the $1,445,890 allocated to non-oil and gas assets
   that were purchased in the merger and sold on March 3, 1997 for $1,445,890.

        On September 30, 1997, the Company completed the acquisition of Shore
   Oil Company ("Shore"). The transaction consisted of a merger (the "Shore
   Merger") of Shore into Shore Acquisition Company Inc., a wholly-owned
   subsidiary of the Company. On September 30, 1997, Shore Acquisition Company
   merged into Shore and its separate corporate existence ceased. Shore was
   merged into the Company on January 1, 1998.

</TABLE>

        The fair value of the securities issued in connection with the merger
   was calculated using the average price of the Company's common stock at the
   time the Shore Merger was announced to the public and further adjusted for
   tradability restrictions. An independent valuation firm determined the
   tradability discount for the Company's common stock.

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

   (2)  ACQUISITIONS (continued)

        As part of the Enex Acquisition, the Company entered into an agreement,
   effective April 15, 1998, with the former president of Enex that provides for
   monthly payments of $20,000 until expiration of the agreement on May 18,
   2002. The monthly payments serve as consideration for consulting, a covenant
   not to compete and a preferential right to purchase certain oil and gas
   acquisitions which the former president controls or proposes to acquire
   during the term of the agreement. The Company will reimburse the former
   president each month for reasonable and necessary business expenses incurred
   in connection with the performance of consulting services. The agreement
   survives the former president and his spouse and is nonassignable. The
   present value of the agreement, applying a 10% discount, is approximately
   $788,563 with the long-term portion classified as other liabilities.

        The cost of acquiring the 79.20% of Enex was allocated using the
   purchase method of accounting to the consolidated assets and liabilities of
   Enex based on estimates of the fair values with the remaining purchase price
   allocated to proved oil and gas properties.

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

        On April 16, 1998, the Company acquired substantially all of the oil and
   gas assets of Service Drilling Co., LLC and certain affiliates ("Service
   Drilling"), in exchange for 666,000 shares of Company common stock and
   $6,500,000 in cash for a total acquisition cost of $11,578,250, before
   post-closing adjustments (the "Service Acquisition"). The effective date of
   the acquisition was March 1, 1998 and the cost was allocated using the
   purchase method of accounting.

        On July 17, 1998, the Securities and Exchange Commission declared
   effective a registration statement filed under the Securities Act of 1933 for
   the merger of Enex into the Company (the "Enex Merger"). A special meeting of
   the stockholders of Enex was held on August 20, 1998 to approve the Enex
   Merger. Due to market conditions, the Company voted against the Enex Merger.
   As of September 30, 1998, the Company owns approximately 79.2% of Enex.

        The Company filed a preliminary registration statement on July 31, 1998
   for the merger of the Enex Partnership into the Company (the "Enex
   Partnership Merger"). At September 30 the Enex Partnership Merger was not
   completed.

   (2)  ACQUISITIONS (concluded)

        As of September 30, 1998 the Company had capitalized approximately
   $313,000 in legal, accounting and other fees for preparation of the
   registration statements for the Enex and the Enex Partnership Mergers. Due to
   the postponement of the Enex Merger, the Company impaired the capitalized
   deal costs related to the Enex Merger by approximately $30,000.

   (3)  ACCOUNTS RECEIVABLE-INSURANCE CLAIM

        The Company owns a 100% working interest in the Louis Mayard #1 well
   located in Vermillion Parish, Louisiana. The Louis Mayard #1 (the "well") had
   been shut in and the Company began a recompletion attempt on or about August
   6, 1998. On August 11, 1998, an attempt to kill the well was made and it was
   determined that the tubing and intermediate casing had failed resulting in an
   uncontrolled underground flow. Due to the inability of the Company to shut in
   the well using regular methods, special crews were called in to gain control
   of the well. The well was shut in on or about October 9, 1998. The costs
   incurred by the Company, through September 30, to gain control of the well
   were approximately $1,404,000. The Company has a $3.0 million control of well
   insurance policy that will reimburse the Company for the costs incurred to
   regain control of the well. On November 4 the insurance company made a
   partial payment to the Company of approximately $1,408,000. At September 30,
   the Company had recorded the estimated amount due from the insurance company
   in current assets as Accounts Receivable-Insurance Claim.

   (4)  RELATED PARTY TRANSACTIONS

        The Company had a note receivable, including accrued interest, from Bay
   City Energy Group, Inc. (BCEG), an entity controlled by certain members of
   the Company's management and directors, as of September 30, 1998 and December
   31, 1997 in the amount of $171,377 and $166,165, respectively. The principal
   balance of the note accrues interest at 5% per annum and is due in full on
   January 1, 2001. 75,000 shares of Company common stock secure the note.
   During the nine months ended September 30, 1998 and 1997, BCEG did not make
   any payments and was not advanced any funds. Interest of $32,373 was accrued
   on the note at September 30, 1998.

        The Company rents office space in Wichita, Kansas from C.J. Lett III, a
   shareholder, officer and director of the Company. The rent is $3,000 per
   month for three years through February, 2000.

        The Company loaned Frank C. Turner II, Vice-President and Chief
   Financial Officer, $14,400 in September, 1998 to pay income taxes associated
   with the exercise of incentive stock options.

   (5)  LONG-TERM DEBT (continued)

        Effective March 27, 1998 the Company entered into a new reducing
   revolving line of credit agreement (the "$100 million Revolver") with Compass
   Bank, as agent and lender, and Bank of Oklahoma, as a participant lender,
   (collectively, the "Banks"). The $100 million Revolver provided for an
   initial borrowing base of $29 million. The initial borrowing base was reduced
   to $27.5 million ten days after the effective date and further reduced by
   $275,000 per month, beginning May 1, 1998 and ending October 1, 1998. In
   conjunction with the Service Acquisition, the borrowing base was increased to
   $32.6 million and the monthly borrowing base reductions were increased to
   $330,000. Effective October 1, 1998, the semi-annual borrowing base
   redetermination date, the borrowing base was calculated to be approximately
   $28.9 million with monthly borrowing base reductions of $250,000 beginning
   November 1, 1998. Effective January 1, 1999, the borrowing base determined at
   October 1, 1998 will be adjusted to $25.4 million if the Company is not
   successful in acquiring the minority interest in the Enex Partnership (the
   "Enex Partnership Merger"). If the Company successfully completes the Enex
   Partnership Merger, the borrowing base determined at October 1, 1998 will be
   readjusted to $33.1 million and the monthly borrowing base reduction will be
   increased to $290,000.

        The principal is due at maturity, April 1, 2001. Monthly principal
   payments are made as required in order that the outstanding principal balance
   does not exceed the borrowing base. Interest is payable monthly and is
   calculated at the prime rate. The Company may also elect to calculate
   interest under the Libor rate, as defined in the agreement. The Libor rate
   increases by (a) 2.00% if the outstanding loan balance and letters of credit
   are equal to or greater than 75% of the borrowing base, (b) 1.75% if the
   outstanding loan balance and letters of credit are less than 75% or greater
   than 50% of the borrowing base, (c) 1.50% if the outstanding loan balance and
   letters of credit are equal to or less than 50% of the borrowing base. Libor
   interest is payable at maturity of the Libor loan which cannot be less than
   thirty days.

        At September 30, 1998 the Company had borrowed approximately $27,454,567
   and had approximately $550,432 of outstanding letters of credit. As of
   September 30, 1998, the Company is paying Libor plus 2.00% on a sixty day
   Libor loan for $25,469,605 and prime on $1,984,962.

   (5)  LONG-TERM DEBT (concluded)

        The Company paid a facility fee equal to 3/8% of the initial borrowing
   base and is required to pay 3/8% on any future increase in the borrowing base
   within five days of written notice. The Company is required to pay a
   quarterly commitment fee on the unused portion of the borrowing base of
   one-half percent if the outstanding loan balance plus letters of credit are
   greater than 50% of the borrowing base or three-eighths percent if the
   outstanding loan balance plus letters of credit are less than or equal to 50%
   of the borrowing base. The Company is required to pay a letter of credit fee
   on the date of issuance or renewal of each letter of credit equal to the
   greater of $500 or one and one-half percent of the face amount of the letter
   of credit.

        The Company has granted to the Banks liens on substantially all of the
   Company's oil and natural gas properties, whether currently owned or
   hereafter acquired, and a negative pledge on all other oil and gas
   properties.

        The $100 million Revolver requires, among other things, a cash flow
   coverage ratio of 1.25 to 1.00 and a current ratio, excluding current
   maturities of the $100 million Revolver, of 0.9 to 1.00, determined on a
   quarterly basis. As of September 30, 1998 the Company was in violation of the
   cash flow covenant, with cash flow coverage of 0.66. The Company has received
   a waiver from the Banks for the twelve months ending September 30, 1999.

        Under the terms of the $100 million Revolver, when mortgaged properties
   are sold the borrowing base shall be reduced, and if necessary, proceeds from
   the sales of properties shall be applied to the debt outstanding in an amount
   equal to the loan value attributable to such properties sold. Of the total
   proceeds received from property sales, $2,145,000 was used to repay principal
   on the $100 million Revolver (See Note 11).

        The $100 million Revolver includes other covenants prohibiting cash
   dividends, distributions, loans, advances to third parties in excess of
   $100,000, or sales of assets greater than 10% of the aggregate net present
   value of the oil and gas properties in the borrowing base.

   (6)  SERIES A PREFERRED STOCK

        On September 4, 1996, the Company signed a stock purchase agreement with
   Kaiser Francis Oil Company ("Kaiser-Francis"). Kaiser-Francis agreed to
   purchase 1,666,667 shares of Series A Preferred Stock ("Series A") at $6.00
   per share, for a total investment of $10,000,000. The parties agreed to a
   five-year purchase period, effective September 4, 1996, with minimum
   incremental investments of $500,000 each. Each issuance of Series A was
   subject to approval by Kaiser-Francis of the use of proceeds. The Series A
   was nonvoting and accrued dividends at 8% per annum, payable quarterly in
   cash. The Series A was convertible at any time after issuance into shares of
   common stock at the rate of two shares of common stock for each share of
   Series A before January 1, 1998. The conversion rate decreases for every full
   year (excluding partial years) thereafter at 8% per annum. As of December 31,
   1997, 1,666,667 shares of the Series A had been issued. On January 31, 1998
   Kaiser-Francis converted 100% of the Series A into 3,333,334 common shares of
   the Company.

   (7)  SERIES B PREFERRED STOCK

        In connection with the merger with Shore Oil Company, effective
   September 30, 1997, the Company issued 266,667 shares of Series B Preferred
   Stock ("Series B"). The Series B is nonvoting and pays no dividends. The
   Series B has a liquidation value of $7.50 per share and was junior to the
   Series A Preferred. For a period of sixty-six months subsequent to September
   30, 1997 any holder of the Series B may convert all or any portion of Series
   B shares into Company Common Stock ("Common") at a ratio of one share of
   Common for each Series B share, or at any time on or after January 1, 1998,
   the holders may convert a portion of their Series B shares based on a

        The Alternative Conversion Factor is then multiplied by 1,066,000 to
   arrive at the potential converted number of common shares received. Upon
   expiration of the conversion period, unless the Company has given notice to
   redeem the Series B, all of the shares of Series B shall be automatically
   converted. In no event shall the aggregate total number of shares of Common
   into which the Series B are converted be less than 266,667 shares or exceed
   1,333,333 shares, unless further increased for any anti-dilution provisions.

   (10) COMMITMENTS AND CONTINGENCIES

        The Company is obligated under the terms of certain operating leases for
   office space that expire over the next three years. The Company is leasing
   3,000 square foot of office space for its Midcontinent office in Wichita,
   Kansas for $3,000 per month for three years ending February 2000. The Company
   is leasing 5,363 square foot of office space for its headquarters in Houston,
   Texas. The twenty-four month lease requires monthly lease payments of $5,791
   through September 30, 1998 and $6,576 through September 30, 1999.

        As of September 30, 1998 the Company had $550,432 of irrevocable standby
   letters of credit due to expire on September 30, 1999.

        Enex, as general partner of the Enex Partnership, is contingently liable
   for all debts and actions of the Enex Partnership. However, in management's
   opinion, the existing assets of the Enex Partnership are sufficient to
   satisfy any such partnership indebtedness.

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

   (11) NON-STRATEGIC PROPERTY SALE

        On August 13, 1998 the Oil and Gas Asset Clearinghouse auctioned several
   hundred oil and gas properties owned by the Company. The auctioned properties
   included properties acquired in the Enex and Service Acquisitions. Certain
   non-strategic properties were subject to minimum bid. The majority of the
   properties were sold by auction with no minimum bids. The Company received
   net proceeds of $2,635,000 from the sale of properties at the auction.

        During the current period, the Company also sold certain other
   non-strategic oil and gas properties in private sales for gross proceeds of
   $1,860,000.

standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material

We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of Enex Consolidated Partners, L.P. at December

                          NOTES TO FINANCIAL STATEMENTS

1. PARTNERSHIP ORGANIZATION

         Enex Consolidated Partners, L.P. (the "Company") was formed under the
New Jersey Uniform Limited Partnership Law (1976) on June 30, 1997 from the
combination of thirty-four Enex Oil and Gas Limited Partnerships, consisting of
Enex Program I Partners, L.P., four partnerships in Enex Oil & Gas Income
Program II, the eight partnerships in Enex Oil & Gas Income Program III, six
partnerships in Enex Oil & Gas Income Program IV, the five partnerships in Enex
Oil & Gas Income Program V, Enex Oil & Gas Income Program Vl - Series 1, L.P.,
the three partnerships in Enex Income and Retirement Fund, three partnerships in
Enex 88-89 Income and Retirement Fund, and the three partnerships in Enex 90-91
Income and Retirement Fund (collectively the "Predecessor Partnerships").

         The historical information presented in this Form 10-KSB consists of
the cumulative historical totals of the Predecessor Partnerships for the year
ended December 31, 1996 and for the six months ended June 30, 1997. The amounts
for the six months ended December 31, 1997 are the result of the operations of
the Company. The Consolidation created a new accounting basis in the carrying
value of property. Oil and gas property was written down by $1,561,322 from the
net carrying value of property in the combined Predecessor Partnerships.

         Information relating to the allocation of costs and revenues between
Enex, as general partner, and the limited partners is as follows:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


         Oil and Gas Properties - The Company uses the successful efforts method
of accounting for its oil and gas operations. Under this method, the costs of
all development wells are capitalized. Capitalized costs are amortized on the
units-of-production method based on estimated total proved reserves. The
acquisition costs of proved oil and gas properties are capitalized and
periodically assessed for impairments.

         The Financial Accounting Standards Board has issued Statement of
Financial Accounting Standard ("SFAS") No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," which
requires certain assets to be reviewed for impairment whenever events or
circumstances indicate the carrying amount may not be recoverable. Prior to this
pronouncement, the Predecessor Partnerships assessed properties on an aggregate
basis. Upon adoption of SFAS 121, the Predecessor Partnerships began assessing
properties on an individual basis, wherein total capitalized costs may not
exceed the property's fair market value. The fair market value of each property
was determined by H. J. Gruy and Associates, ("Gruy"). To determine the fair
market value, Gruy estimated each property's oil and gas reserves, applied
certain assumptions regarding price and cost escalations, applied a 10% discount
factor for time and certain discount factors for risk, location, type of
ownership interest, category of reserves, operational characteristics, and other
factors. In the first quarter of 1996, the Company recognized a non-cash
impairment provision of $2,315,081 for certain oil and gas properties due to
changes in the overall market for the sale of oil and gas and significant
decreases in the projected production from certain of the Company's oil and gas
properties.

         The Company's operating interests in oil and gas properties are
recorded using the pro rata consolidation method pursuant to Interpretation 2 of
Accounting Principles Board Opinion 18.

         Cash Flows - The Company has presented its cash flows using the
indirect method and considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.

         General and Administrative Expenses - The Company reimburses the
General Partner for direct costs and administrative costs incurred on its
behalf. Administrative costs allocated to the Company are computed on a cost
basis in accordance with standard industry practices by allocating the time
spent by the General Partner's personnel among all projects and by allocating
rent and other overhead on the basis of the relative direct time charges.

         Use of Estimates - The preparation of the 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 revenue and expenses during
the reporting periods. Actual results could differ from these estimates.

3. FEDERAL INCOME TAXES


         General - The Company is not a taxable entity for federal income tax
purposes. Such taxes are liabilities of the individual partners, and the amounts
thereof will vary depending on the individual situation of each partner.
Accordingly, there is no provision for income taxes in the accompanying
financial statements. Set forth below is a reconciliation of net income as
reflected in the accompanying financial statements and net income (loss) for
federal income tax purposes for the year ended December 31, 1997:

4. SIGNIFICANT PURCHASERS

         Gulfmark Inc. accounted for 11% of the Company's total sales in 1997.
Dreyfus Energy, Inc., Exxon Company, USA and Koch Hydrocarbons, Inc. accounted
for 14%, 14% and 10%, respectively, of the Company's total sales in 1996. No
other purchaser individually accounted for more than 10% of such sales.

5. LITIGATION SETTLEMENTS

         A Predecessor Partnership was named as a party to a suit filed by Texas
Crude, Inc. ("Texas Crude"). In the suit, Texas Crude sought to recover legal
and other fees totaling $600,000. In August 1993, a judgement was granted in
favor of Texas Crude for $414,203 plus interest by the 101st Judicial District
Court of Texas. The Partnership recognized a contingent liability at December
31, 1993 for $504,350.

         The Partnership appealed the verdict and filed a counterclaim for funds
that were wrongfully withheld by Texas Crude. In December 1994, the Fifth
District Court of Appeals reversed the judgement of the trial court and rendered
judgement in favor of the Partnership, in which the Partnership will recover
$163,019 from Texas Crude plus interest. Accordingly, the contingent liability,
initially recognized in 1993, was reversed in December 1994 and a receivable for
$254,588 was established in 1994.

         Both the Partnership and Texas Crude have filed Motions for Rehearing,
which have been pending for several years. Interest has accrued on the
receivable balance at a rate of ten percent (10%) per annum. The accrued
receivable balance at December 31, 1997 was $338,860.

6. PROPERTY TRANSACTIONS

         In 1996, the Predecessor Partnerships sold their interests in the Grass
Island, Enexco and Comite acquisitions for $235,000, $64,000 and $55,000,
respectively. Gains of $69,731, $61,648 and $21,649, respectively were
recognized on these sales. The Predecessor Partnerships also sold their
interests in the E.M. Lane well and the Harper #1 wed for $57,970 and $55,000,
respectively. Gains of $31,310 and $44,642, respectively, were recognized on
these
                                      F-53

sales. The Predecessor Partnerships also sold their interests in three other
wells in 1996 for $59,630. These sales resulted in a net gain of $13,409 to the
Predecessor Partnerships. The impact of these sales on current and future
revenues is not expected to be material, as such interests represented less than
10% of historical and future net revenues.

         In 1997, the Company sold its interest in the North Buck Draw Unit for
$857,120. A gain of $758,969 was recognized on the sale. The Company sold its
interest in the Mcbride acquisition for $56,306. A loss of $25,405 was
recognized on the sale. The Company also sold its interest in three other
acquisitions for $8,053. A net gain of $8,053 was recognized by the Company from
the sales. The impact of these sales on current and future revenues is not
expected to be material, as such interests represented less than 10% of
historical and future net revenues.

7. PAYABLE TO GENERAL PARTNER

         The payable to general partner primarily consists of general and
administrative expenses allocated to the Company by Enex for its ongoing
operations. The Company plans to repay the amounts owed to the general partner
during 1998.

8. SUBSEQUENT EVENT

         In February 1998, Middle Bay Oil Company, Inc. ("Middle Bay"), an
independent oil and gas producer, announced a tender offer for all of the
outstanding shares of Enex Resources Corporation, the Company General Partner.
The tender offer was accepted by a majority of Enex's shareholders.

ENEX CONSOLIDATED PARTNERS, L.P.

NOTES TO UNAUDITED FINANCIAL STATEMENTS

1.       Effective June 30, 1997, Enex Consolidated Partners, L.P. (the
         "Company") was formed from the consolidation of thirty-four (34)
         partnerships consisting of Enex Program I Partners, L.P., four
         partnerships in Enex Oil & Gas Income Program II, the eight
         partnerships in Enex Oil & Gas Income Program III, six partnerships in
         Enex Oil & Gas Income Program IV, the five partnerships in Enex Oil &
         Gas Income Program V, Enex Oil & Gas Income Program VI - Series 1,
         L.P., the three partnerships in Enex Income and Retirement Fund, three
         partnerships in Enex 88-89 Income and Retirement Fund, and the three
         partnerships in Enex 90-91 Income and Retirement Fund (collectively the
         "Partnerships").

         The consolidation of the Company was recorded using the purchase method
         of accounting; as such, assets are recorded at their fair market value.
         The statements of operations and cash flows, in the accompanying
         financial statements, are presented on a combined historical basis. The
         balance sheet has been adjusted to reflect the conversion of the
         payable to the general partner and the general partner's capital
         account into limited partner capital units. The general partner has a
         4.11% revenue interest in addition to its proportional interest as a
         limited partner of 56.2%.

2.       The interim financial information included herein is unaudited;
         however, such information reflects all adjustments (consisting solely
         of normal recurring adjustments) which are, in the opinion of
         management, necessary for a fair presentation of results for the
         interim periods.

3.       Effective January 1, 1997, the Company sold its interests in the
         Perkins well in the Burkholder acquisition for $5,940. A gain of $5,940
         was recognized on this sale.

         Effective January 1, 1998, the Company sold its interest in the Dover
         Hennessey Gas Plant for $1,000,000. A gain of $671,923 was recognized
         on the sale. Effective June 1, 1998 the Company sold its interest in
         the Corkscrew acquisition for $36,000. A loss of $167,302 was
         recognized on the sale. Effective July 1, 1998 the Company sold its
         interest in the Brown 1 and 2 wells for $8,000. A gain of $4,171 was
         recognized on the sale. Effective September 1, 1998 the Company sold
         its interest in numerous properties in a August 1998 auction for
         $929,063. A gain of $542,881 was recognized on the sale.

4.       In February 1998, Middle Bay Oil Company, Inc., an independent oil and
         gas producer, announced a tender offer for all of the outstanding
         shares of Enex Resources Corporation ("Enex"), the Company's general
         partner. The tender offer was accepted by a majority of Enex
         shareholders and was completed on March 27, 1998.

</TABLE>

The estimated fair market value of the partnership is $10,380,000.




<PAGE>   208



FAIR MARKET VALUE AS USED HEREIN IS THE PRICE THAT A WILLING BUYER WILL PAY AND
A WILLING SELLER WILL ACCEPT AT A GIVEN POINT IN TIME, WITH NEITHER THE BUYER
NOR THE SELLER UNDER ANY COMPULSION TO BUY OR SELL, AND BOTH HAVING REASONABLE
KNOWLEDGE OF ALL THE MATERIAL CIRCUMSTANCES.

To estimate the fair market value attributable to the proved developed producing
reserves, the 10 percent discounted future net cash flow was adjusted to reflect
the impact of federal income tax. The internal rate of return and payout time
were computed for this quantity and compared with those at which current
acquisitions are completed. Suitable adjustments were then made to correspond to
these two financial indices. Proved developed nonproducing reserves are treated
similarly except that an additional adjustment is made for the capital
expenditure. For probable and possible reserves, the capital is added to the
discounted net cash flow, then multiplied by a suitable factor to account for
category risk and the capital then subtracted. This has the effect that capital
is spent with certainty and the operating cash income is burdened with the risk.
Internal rate of return and payout time are calculated for each to establish
reasonableness based upon the risk associated with the reserve category.

The estimated future net cash flow is that cash flow which will be realized from
the sale of the estimated net production after deduction of royalties, ad
valorem and production taxes, direct operating costs, and capital expenditures,
when applicable. Surface and well equipment salvage values, and well plugging
and field abandonment costs have not been considered in the cash flow
projections. Future net cash flow as stated in this report is before the
deduction of federal or state income tax.

The following parameters are incorporated in the economic projections referenced
in this report. Base oil, natural gas, and natural gas liquids prices are shown
in Table I. These prices are the average NYMEX prices for oil and natural gas
for the years 1998 through 2000. After the year 2000, prices are escalated at an
annual rate of 2.5 percent until the primary product reaches its maximum. Oil
and condensate prices are adjusted for gravity and transportation charges and
natural gas prices are adjusted for BTU content and transportation. Operating
expenses are escalated at an annual rate of 2.5 percent until the primary
product reaches its maximum value. The actual prices that will be received and
the associated costs may be more or less than those projected.

The liquidation value of the partnership was estimated to be $8,861,000. This
estimate assumes the orderly liquidation of partnership assets over a 12 month
period. In connection therewith, it is assumed that the partnership would incur
a total of $1,000,000 in general and administrative fees and approximately five
percent for third party expenses including broker fees, legal and land fees,
printing costs, and miscellaneous expenses.

For those wells with sufficient production history, reserve estimates and rate
projections are based on the extrapolation of established performance trends.
Reserves for other producing and nonproducing properties have been estimated
from volumetric calculations and analogy with the performance of comparable
wells. The reserves referenced in this study are estimates only and

should not be construed as exact quantities. Future conditions may affect
recovery of estimated reserves and cash flow, and all categories of reserves may
be subject to revision as more performance data become available. Since this
work constitutes a fair market opinion, Gruy has a fiduciary obligation to the
partners to provide a value for all reserve categories; i.e., proved, probable,
and possible. The proved reserves are estimated in accordance with the
definitions included in the Securities and Exchange Commission Regulation S-X,
Rule 4-10(a) EXCEPT FOR THE PRICE AND COST ESCALATIONS. The definitions are
included in part as Attachment I. The probable and possible reserves conform to
the definitions approved by the Society of Petroleum Engineers, Inc. because the
SEC definitions do not include probable and possible reserves. These definitions
are included as Attachment II.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates, and other data provided by
Middle Bay have been accepted as represented. The production data available to
us were at least through the month of November 1997, but nearly all producing
properties had data available through June 1998. Interim production to October
1, 1998, has been estimated. Operating expenses as supplied by Middle Bay were
not audited, but were reviewed for reasonableness. No independent well tests,
property inspections, or audits of operating expenses were conducted by our
staff in conjunction with this study. We did not verify or determine the extent,
character, obligations, status, or liabilities, if any, arising from any current
or possible future environmental liabilities that might be applicable.

In order to estimate the reserves, costs, and future cash flows referenced in
this report, we have relied in part on geological, engineering, and economic
data furnished by our client. Although we have made a best efforts attempt to
acquire all pertinent data and to analyze it carefully with methods accepted by
the petroleum industry, there is no guarantee that the volumes of oil or gas or
the cash flows projected will be realized. The reserve and cash flow projections
referenced in this report may require revision as additional data become
available.

H.J. Gruy and Associates, Inc. is unrelated to Middle Bay or Enex and has no
interest in the properties included in this report. In particular:

        1. We do not own a financial interest in Middle Bay or Enex or its oil

                 DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)

PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.

PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.

PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                         PETROLEUM RESERVES DEFINITIONS

   SOCIETY OF PETROLEUM ENGINEERS (SPE) AND WORLD PETROLEUM CONGRESS (WPC)(1)

Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward. All
reserve estimates involve some degree of uncertainty. The uncertainty depends
chiefly on the amount of reliable geologic and engineering data available at the
time of the estimate and the interpretation of these data. The relative degree
of uncertainty may be conveyed by placing reserves into one of two principal
classifications, either proved or unproved. Unproved reserves are less certain
to be recovered than proved reserves and may be further sub-classified as
probable and possible reserves to denote progressively increasing uncertainty in
their recoverability.

The intent of the SPE and WPC in approving additional classifications beyond
proved reserves is to facilitate consistency among professionals using such
terms. In presenting these definitions, neither organization is recommending
public disclosure of reserves classified as unproved. Public disclosure of the
quantities classified as unproved reserves is left to the discretion of the
countries or companies involved.

Estimation of reserves is done under conditions of uncertainty. The method of
estimation is called deterministic if a single best estimate of reserves is made
based on known geological, engineering and economic data. The method of
estimation is called probabilistic when the known geological, engineering, and
economic data are used to generate a range of estimates and their associated
probabilities. Identifying reserves as proved, probable, and possible has been
the most frequent classification method and gives an indication of the
probability of recovery. Because of potential differences in uncertainty,
caution should be exercised when aggregating reserves of different
classifications.

Reserves estimates will generally be revised as additional geologic or
engineering data become available or as economic conditions change. Reserves do
not include quantities of petroleum being held in inventory, and may be reduced
for usage of processing losses if required for financial reporting.

Reserves may be attributed to either natural energy or improved recovery
methods. Improved recovery methods include all methods for supplementing natural
energy or altering natural forces in the reservoir to increase ultimate
recovery. Examples of such methods are pressure maintenance, cycling,
waterflooding, thermal methods, chemical flooding, and the use of miscible and
immiscible displacement fluids. Other improved recovery methods may be developed
in the future as petroleum technology continues to evolve.



PROVED RESERVES

Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations. Proved reserves can be categorized as developed or undeveloped.

If deterministic methods are used, the term reasonable certainty is intended to
express a high degree of confidence that the quantities will be recovered. If
probabilistic methods are used, there should be at least a 90% probability that
the quantities actually recovered will equal or exceed the estimate.

Establishment of current economic conditions should include relevant historical
petroleum prices and associated costs and may involve an averaging period that
is consistent with the purpose of the reserve estimate, appropriate contract
obligations, corporate procedures, and government regulations involved in
reporting these reserves.

In general, reserves are considered proved if the commercial producibility of
the reservoir is supported by actual production or formation tests. In this
context, the term proved refers to the actual quantities of petroleum reserves
and not just the productivity of the well or reservoir. In certain cases, proved
reserves may be assigned on the basis of well logs and/or core analysis that
indicate the subject reservoir is hydrocarbon bearing and is analogous to
reservoirs in the same area that are producing or have demonstrated the ability
to produce on formation tests.

The area of the reservoir considered as proved includes (1) the area
delineated by drilling and defined by fluid contacts, if any, and (2) the
undrilled portions of the reservoir that can reasonably be judged as
commercially productive on the basis of available geological and engineering
data. In the absence of data on fluid contacts, the lowest known occurrence of
hydrocarbons controls the proved limit unless otherwise indicated by definitive
geological, engineering or performance data.

(SPE), Inc. on March 7, 1997.




<PAGE>   216


Reserves may be classified as proved if facilities to process and transport
those reserves to market are operational at the time of the estimate or there is
a reasonable expectation that such facilities will be installed. Reserves in
undeveloped locations may be classified as proved undeveloped provided (1) the
locations are direct offsets to wells that have indicated commercial production
in the objective formation, (2) it is reasonably certain such locations are
within the known proved productive limits of the objective formation, (3) the
locations conform to existing well spacing regulations where applicable, and (4)
it is reasonably certain the locations will be developed. Reserves from other
locations are categorized as proved undeveloped only where interpretations of
geological and engineering data from wells indicate with reasonable certainty
that the objective formation is laterally continuous and contains commercially
recoverable petroleum at locations beyond direct offsets.

Reserve which are to be produced through the application of established improved
recovery methods are included in the proved classification when (1) successful
testing by a pilot project or favorable response of an installed program in the
same or an analogous reservoir with similar rock and fluid properties provides
support for the analysis on which the project was based, and, (2) it is
reasonably certain that project will proceed. Reserves to be recovered by
improved recovery methods that have yet to be established through commercially
successful applications are included in the proved classification only (1) after
a favorable production response from the subject reservoir from either (a) a
representative pilot or (b)an installed program where the response provides
support for the analysis on which the project is based and (2) it is reasonably
certain the project will proceed.

UNPROVED RESERVES

Unproved reserves are based on geologic and/or engineering data similar to that
used in estimates of proved reserves; but technical, contractual, economic, or
regulatory uncertainties preclude such reserves being classified as proved.
Unproved reserves may be further classified as probable reserves and possible
reserves.

Unproved reserves may be estimated assuming future economic conditions different
from those prevailing at the time of the estimate. The effect of possible future
improvements in economic conditions and technological developments can be
expressed by allocating appropriate quantities of reserves to the probable and
possible classifications.

PROBABLE RESERVES

Probable reserves are those unproved reserves which analysis of geological and
engineering data suggests are more likely than not to be recoverable. In this
context, when probabilistic methods are used, there should be a least a 50%
probability that the quantities actually recovered will equal or exceed the sum
of estimated proved plus probable reserves.

In general, probable reserves may include (1) reserves anticipated to be proved
by normal step-out drilling where subsurface control is inadequate to classify
these reserves as proved, (2) reserves in formations that appear to be
productive based on well log characteristics but lack core data or definitive
tests and which are not analogous to producing or proved reservoirs in the area,
(3) incremental reserves attributable to infill drilling that could have been
classified as proved if closer statutory spacing had been approved at the time
of the estimate, (4) reserves attributable to improved recovery methods that
have been established by repeated commercially successful applications when (a)
a project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir characteristics appear favorable for commercial application, (5)
reserves in an area of the formation that appears to be separated from the
proved area by faulting and the geologic interpretation indicates the subject
area is structurally higher than the proved area, (6) reserves attributable to a
future workover, treatment, re-treatment, change of equipment, or other
mechanical procedures, where such procedure has not been proved successful in
wells which exhibit similar behavior in analogous reservoirs, and (7)
incremental reserves in proved reservoirs where an alternative interpretation of
performance or volumetric data indicates more reserves than can be classified as
proved.


POSSIBLE RESERVES

Possible reserves are those unproved reserves which analysis of geological and
engineering data suggests are less likely to be recoverable than probable
reserves. In this context, when probabilistic methods are used, there should be
a least a 10% probability that the quantities actually recovered will equal or
exceed the sum of estimated proved plus probable plus possible reserves.





In general, possible reserves may include (1) reserves which, based on
geological interpretations, could possibly exist beyond areas classified as
probable, (2) reserves in formations that appear to be petroleum bearing based
on log and core analysis but may not be productive at commercial rates, (3)
incremental reserves attributed to infill drilling that are subject to technical
uncertainty, (4) reserves attributed to improved recovery methods when (a) a
project or pilot is planned but not in operation and



<PAGE>   217

(b) rock, fluid, and reservoir characteristics are such that a reasonable doubt
exists that the project will be commercial, and (5) reserves in an area of the
formation that appears to be separated from the proved area by faulting and
geological interpretation indicates the subject area is structurally lower than
the proved area.



RESERVE STATUS CATEGORIES

Reserve status categories define the development and producing status of wells
and reservoirs.

         DEVELOPED: Developed reserves are expected to be recovered from
         existing wells including reserves behind pipe. Improved recovery
         reserves are considered developed only after the necessary equipment
         has been installed, or when the costs to do so are relatively minor.
         Developed reserves may be sub-categorized as producing or
         non-producing.

                  PRODUCING: Reserves subcategorized as producing are expected
                  to be recovered from completion intervals which are open and
                  producing at the time of the estimate. Improved recovery
                  reserves are considered producing only after the improved
                  recovery project is in operation.

                  NON-PRODUCING. Reserves subcategorized as non-producing
                  include shut-in and behind-pipe reserves. Shut-in reserves are
                  expected to be recovered from 1) completion intervals which
                  are open at the time of the estimate but which have not
                  started producing, (2) wells which were shut-in for market
                  conditions or pipeline connections (3) wells not capable of
                  production for mechanical reasons. Behind-pipe reserves are
                  expected to be recovered from zones in existing wells, which
                  will require additional completion work or future recompletion
                  prior to the start of production.

         UNDEVELOPED RESERVES: Undeveloped reserves are expected to be
         recovered: (1) from new wells on undrilled acreage, (2) from deepening
         existing wells to a different reservoir, or (3) where a relatively
         large expenditure is required to (a) recomplete an existing well or (b)
         install production or transportation facilities for primary or improved
         recovery projects.

         The non-consenting Investor signing in this Part IV represents that
California is the Investor's state of residence and withholds his consent to the
Proposal to approve and adopt the Amendment to the Partnership Agreement. By
withholding consent, a non-consenting California Investor will exercise his

warranties and covenants (other than the consent to the adoption of the
Proposal) set forth in Part II above, and he will receive, pursuant to those
dissenters' rights, a cash amount equal to the fair market value of the
non-consenting California Investor's Partnership Units determined as of November
25, 1998, the day before the first announcement of the terms of the Proposal.
This amount may be more or less than the non-consenting California Investor
would receive under the Exchange Offer.

         The non-consenting Investor signing in this Part V withholds his or

Partnership Agreement. By withholding consent, a non-consenting Investor will
exercise his or her dissenter's rights and will be deemed to have made the

adoption of the Proposal) set forth in Part II above, and he or she will
receive, pursuant to those contractual dissenters' rights granted under Section
8.10 of the Amended Articles of Limited Partnership of Enex Consolidated
Partners, L.P. a cash payment equal to the number of Units held by the Investor,
multiplied by the percent value of all Units as determined by an independent
expert instructed to assume an orderly liquidation of Partnership assets over a
12-month period. The Gruy Report, including a summary of the appraisal
indicating all material assumptions underlying the appraisal, is included as
Exhibit "A" to the Prospectus.

                                    PART VI
                                  INSTRUCTIONS

         1.       Previously Transferred Units. If an Investor has transferred,
whether by sale, gift, death or otherwise, the beneficial ownership of any Unit
of which he has been named a holder of record in the accompanying Letter of
Transmittal without previously notifying Middle Bay or complying with the
procedures set forth in the Partnership Agreement for transferring his Units in
the Partnership, he or she should notify Middle Bay of that fact and identify
the Unit(s) transferred, the date of transfer and the name, address and tax
identification number of the assignee. Middle Bay will then send the Investor
and the assignee revised Letters of Transmittal and request from the Investor or
assignee such other documents as it may require in order to facilitate the
tender, if desired, of an assignee's interest in the Partnership.

         2.       Participation in Exchange. To be entitled to receive the
Series C Preferred stock in the Exchange, even if consent to the Proposal is
withheld, or cash payment if dissenting under Part IV, an Investor must deliver
one originally-executed copy of the Letter of Transmittal, completed, dated and
signed in the Signature Box in Part III, or the Signature Box in Part IV for
non-consenting California residents, or the Signature Box in Part V for other
non-consenting Investors. Delivery is at the risk of the Investor. A tender or
notice of dissent will be effective only when the Letter is actually received by
the Exchange Agent. The Letter must be received by the Exchange Agent on or
before 5:00 p.m. Central Time on December 29, 1998 unless the Exchange Offer is
extended, in which event the Letter must be received by the latest time and date
on which the Exchange Offer, as so extended, will expire. Middle Bay may revoke,
at its sole discretion, any incomplete or non-conforming Letter of Transmittal.

         3.       Signatures. The Letter must be signed by the Investor whose
name appears on page C-1 of the Letter. If the Units are held in the names of
two or more persons, all such persons must sign the Letter. With respect to
Units held by entities such as trusts, joint ventures, limited partnerships or
general partnerships, Middle Bay may require that the Letter of Transmittal be
accompanied by evidence acceptable to Middle Bay that the entity has met all
requirements of its governing instruments, such as applicable partnership or
joint venture agreements, and that the person signing the Letter is authorized
to sign for the Investor under the laws of the jurisdiction in which the entity
was organized.

                  TO PARTICIPATE IN THE EXCHANGE OFFER, AN INVESTOR MUST SIGN IN
THE SIGNATURE BLOCK IN PART III (OR PART IV FOR CALIFORNIA INVESTORS OR PART V
FOR OTHER DISSENTING INVESTORS), EVEN IF THE INVESTOR OBJECTS TO THE EXCHANGE
OFFER AND ELECTS TO WITHHOLD HIS OR HER CONSENT TO THE PROPOSAL. INVESTORS WILL
NOT RECEIVE SHARES IN THE EXCHANGE UNTIL A SIGNED LETTER OF TRANSMITTAL IS
RETURNED.

         4.       Conditional Tenders. No alternative, conditional or contingent
tenders will be accepted.

         5.       Withdrawal of Tenders. Tenders of Units and consents to the
Proposal are revocable at any time prior to the Expiration Date by delivering a
notice of withdrawal to Middle Bay.

         6.       Validity of Tenders. All questions on the validity, form,
eligibility (including time of receipt) and acceptance of Units will be
determined by Middle Bay, and its determination will be final and binding.
Interpretation by Middle Bay of the terms and conditions of the Exchange Offer
(including the instructions to the Letter of Transmittal) will also be final and
binding. Middle Bay reserves the right to waive any



                                     C-7
<PAGE>   226
irregularities or conditions on the manner of tender, and the interpretation by
Middle Bay of the terms and conditions of the Exchange Offer (including the
instructions in the Letter of Transmittal) shall be final and binding. Any
irregularities in connection with tenders must be cured within such time as
Middle Bay shall determine unless waived by it.

                  Tenders will be deemed not to have been made until any
irregularities have been cured or waived. Any Letter of Transmittal which is not
properly completed and executed, and as to which irregularities are not cured or
waived, will be returned by Middle Bay to the Investor as soon as practicable.
Middle Bay is under no duty to give notification of defects in tenders and will
not incur any liability for failure to give notification.

                  Middle Bay will not accept tenders of less than all of an
Investor's Units in the Partnership.

         7.       Consents to Proposal. A tender of a Unit constitutes a consent
to the Proposal. Only persons who are holders of record of Partnership Units on
the date of the Prospectus may vote on the Proposal.

         8.       Contractual Dissenters' Rights. All investors have limited
dissenters' rights under Section 8.10 of the Amended Articles of Limited
Partnership in connection with the proposed Exchange Offer. By signing Part V
and thereby withholding consent to the Proposal, an Investor will be deemed to
exercise his dissenter's rights and will receive a cash payment as indicated in
Part V and as set forth in the Prospectus (please see "The Exchange Offer and
Proposal -- Appraisal and Dissenter's Rights").

         9.       Dissenters' Rights for California Residents. Investors
residing in California have limited dissenters' rights in accordance with the
requirements for roll-up transactions. By signing Part IV and thereby
withholding consent to the Proposal, Investors in that state will be deemed to
exercise their dissenters' rights and will receive cash equal to the fair market
value of their Units as determined as of the day before the first announcement
of the terms of the Exchange Offer. The fair market value amount as so
determined may be greater or less than the value of Series C Preferred shares
which would be received under the Exchange Offer. Each California Investor
withholding consent to the Proposal will also be deemed to have tendered his
Units for that number of Units and therefore will not be required to separately
submit an executed Transfer Application.

                  California residents may choose to exercise their dissenters'
rights either under Part IV or Part V (but not both), and such exercise waives
all dissenters' rights not exercised.

PERSONAL AND CONFIDENTIAL

Middle Bay Oil Company, Inc.
1221 Lamar, Suite 1020
Houston, Texas  77010

Attention:   Board of Directors

Gentlemen:

         You have advised Harris Webb & Garrison, Inc. ("HWG") that Middle Bay
Oil Company, Inc. ("Middle Bay") has proposed to acquire all of the limited
partnership interests (the "Units") in Enex Consolidated Partners, L.P. (the
"Enex Partnership") by offering to the owners of those Units 2.128 shares of
Convertible Redeemable Series C Preferred Stock (the "Preferred Stock") to be
issued by Middle Bay in exchange for each Partnership Unit (the "Exchange").
The Preferred Stock will have a cumulative annual cash dividend rate of $0.50
per share, which is 10% of its stated value of $5.00 per share and will be
convertible, at any time at the option of the holder, into Middle Bay common
stock at a conversion price of $5.00 per share, subject to certain
anti-dilution adjustments. The Preferred Stock will be redeemable at the option
of Middle Bay on and after January 1, 2000 at a redemption price of $5.00 per
share plus accrued and unpaid dividends. You have requested that HWG act as
financial advisor and issue an opinion ("Opinion") as to the fairness to the
public limited partners of the Enex Partnership of the financial terms of the
proposed Exchange.

         HWG, as part of its investment banking business, is frequently engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, secondary distributions of listed
and unlisted securities, private placements, and valuations for estate,

         In arriving at our Opinion, we have, among other things:

                 Registration Statement dated October 14, 1998;

         Reviewed the Enex Partnership's 10-KSB report for the year ended

                 Deloitte & Touche, L.L.P.;

         Reviewed the Enex Partnership's 10-QSB reports for the quarters ended
                 March 31, 1998 and June 30, 1998;

         Reviewed Middle Bay's 10-KSB report for the year ended December 31,
                 1997 with financial statements audited by Schultz, Watkins &
                 Company;

         Reviewed Middle Bay's 10-QSB reports for the quarters ended March 31,
                 1998 and June 30, 1998;

         Reviewed summary pages of the Enex Parnership's reserve reports 
                 prepared by H.J. Gruy and Associates, Inc. as of July 1, 1998
                 and October 1, 1998;

         Reviewed summary pages of Middle Bay's reserve report prepared by
                 Middle Bay as of July 1, 1998 and October 1, 1998;

         Reviewed historical distributions made to limited partners of the Enex 
                 Partnership and its predecessors;

         Discussed with management of Middle Bay and the Enex Partnership the
                 outlook for future operating results, the assets and
                 liabilities of both companies, materials in the foregoing
                 documents, and other matters we considered relevant to our
                 inquiry; and

         Considered such other information, financial studies, analyses and
                 investigations as we deemed relevant under the circumstances.

         In our review and in arriving at our Opinion, we have, with your
permission, (i) not independently verified any of the foregoing information and
have relied upon its being complete and accurate in all material respects, (ii)
with respect to any estimates, evaluations and projections furnished to us,
assumed that such information was reasonably prepared and based upon the best
currently available information and good faith judgement of the person
furnishing the same, and (iii) not made an independent evaluation or appraisal
of specific assets of Middle Bay or the Enex Partnership.

In addition, we have not made a physical inspection of the oil and gas
properties of Middle Bay or the Enex Partnership, nor have we made any
independent evaluations, appraisals or investigations of the other assets of
Middle Bay or the Enex Partnership. In rendering this Opinion, we have not
considered, nor have we reviewed, the terms of the limited partnership
agreement of the Enex Partnership (or other relevant agreements among its
partners), nor have we considered the effect that structural and legal
differences of investment in a limited partnership and a corporation may have
upon the fairness of the Exchange to limited partners of the Enex Partnership.

We are not experts in geological and engineering evaluation of oil and gas
reserves. In rendering our Opinion, we have relied upon, among the other
information described above, the report of H.J. Gruy and Associates, Inc. dated
September 23, 1998 of (i) the net reserves of the Enex Partnership and future
net cash flow and discounted net cash flow thereof as of October 1, 1998 and
(ii) the estimated fair market value and liquidation value of the Enex
Partnership.

Our Opinion is based upon market, economic and other conditions as they exist
and can be evaluated as of the date of this letter. HWG consents to the
inclusion of the text of this Opinion in any notice or appropriate disclosure
to the limited partners of the Enex Partnership and in any filing that Middle
Bay or the Enex Partnership is required by law to make, or include in documents
filed, with the Securities and Exchange Commission.

         Based upon and subject to the foregoing, it is our Opinion that, as of
the date hereof, the proposed Exchange is fair to the public limited
partnership unitholders of the Enex Partnership from a financial point of view.
