ITEM 2.     ACQUISITION AND DISPOSITION OF ASSETS

     On February 10, 1997, Middle Bay Oil Company, Inc. (the "Registrant" or 
"Middle Bay") entered into an Agreement and Plan of Merger with Bison Energy 
Corporation ("Bison") whereby Bison will be merged with a wholly-owned 
subsidiary of Middle Bay in exchange for Middle Bay common stock and cash.
Bison, as the surviving corporation, would become wholly-owned by Middle Bay.

     Bison is a privately-owned domestic exploration and production company 
with assets located in Kansas and Oklahoma.  Pursuant to the Agreement and 
Plan of Merger, Middle Bay will issue 1,167,556 shares of its common stock and 
net cash consideration of $5.9 million, subject to adjustment, to Bison in 
exchange for the stock of Bison. Bison presently owns 562,000 shares of Middle
Bay common stock, which shares would be cancelled upon consumation of the 
merger.  Bison's value was determined by estimating the discounted reserve 
value of its properties and through negotiation.  The cash portion of the 
consideration for the merger is being financed through the issuance of 
1,000,000 shares of Middle Bay Series A Preferred Stock to Kaiser-Francis Oil 
Company ("Kaiser-Francis") for $6,000,000 ($6.00 per preferred share).  The 
preferred shares will be issued on a private placement basis pursuant 
to a Stock Purchase Agreement dated September 4, 1996 between the Company and 
Kaiser-Francis, as reported in the Registrant's Form 8-K Current Report filed 
September 19, 1996.

     The Bison merger is expected to add an estimated 606,681 barrels of oil 
and natural gas liquids and 2.58 billion cubic feet of natural gas to Middle 
Bay's reserves.  Subsequent to the merger, Middle Bay will have total proved 
reserves of approximately 1,996,626, barrels of oil and Ngls, and 11,544,238 
Mcf of Natural gas with a discounted value of $32,465,021.  In addition, 
Middle Bay will acquire approximately 8,860 acres of undeveloped leases, an 
interest in the Spivey-Grabs gas processing plant and operating facilities in 
Attica, Kansas and Cushing, Oklahoma.  The transaction has a discounted value
of $10,000,000 according to Middle Bay's evaluation.

	Closing of the transaction is expected to occur on or before February 28,
1997.

	Bison's president and sole shareholder, C. J. Lett, III, is a party to the 
Agreement and Plan of Merger.  Mr. Lett has agreed to continue as President 
and a Director of Bison, and he will be nominated for election as a Director 
of Middle Bay at the next annual meeting of shareholders.

         F.      The laws of the State of Alabama and the State of Kansas
permit a merger of the Constituent Corporations, and Bison/Alabama and Bison
desire to be merged together, with Bison being the Surviving Corporation and
becoming a wholly-owned subsidiary of Middle Bay in accordance with the terms
of this Agreement.

         G.      The oil and gas assets of Bison are set forth in Exhibit "A"
attached hereto. In such exhibit, the abbreviations "WI" and "NRI" mean working
interest and net revenue interest, respectively, each expressed as a percentage
of all of the interests of the respective well. The term "properties," with
respect to Bison, includes within its meaning, collectively, all of Bison's oil
and gas leasehold interests, other mineral interests, royalty interests and
other rights and interests in, to or related to the wells described in the
respective exhibit, including, without limitation, all such interests, or
portions of any interest, which relate to or affect property upon which the
wells are located. Such term includes within its meaning, additionally, all
wells (producing, nonproducing, injection and disposal wells), all of the
personal property, fixtures, equipment, casing and tubing, compressors,
pipelines, meters, production, gathering, treating, processing, compression,
dehydration, salt water disposal, and pipeline equipment and facilities,

described and listed in the respective exhibit, together with all geological
and geophysical maps, records, land, production and well files in possession of
Bison.

         H.      Middle Bay's professional staff has reviewed and determined
the undiscounted reserve values and the discounted present values of reserves
of the properties. Such values, as determined by Middle Bay, are set forth in
Exhibit "B" attached hereto.

         I.      Lett is the record and beneficial owner of all 500 shares of
the issued and outstanding Bison common stock, constituting 100% of all issued
and outstanding capital stock of Bison.

         J.      The Boards of Directors of Middle Bay and each of the
Constituent Corporations have determined that it is advisable and for the
benefit of Middle Bay and each of the Constituent Corporations and their
respective shareholders that Bison be merged with Bison/Alabama on the terms
and conditions hereinafter set forth, and by resolutions duly adopted have
adopted the terms and conditions of this Agreement; and directed that the
proposed merger be submitted to the shareholders of the Constituent
Corporations and recommended to such shareholders approval of the terms and
conditions hereinafter set forth.

hereinafter set forth and in accordance with the Alabama Business Corporation
Act and the Kansas Business Corporation Act (together, the "Acts"), that Bison
shall be and hereby is, at the Merger Date (as hereinafter defined in Section

hereby agreed upon, the mode of carrying the same into effect and the manner of

Surviving Corporation, and Surviving Corporation shall continue in existence
and the Merger shall in all respects have the effect provided for in Section
10-2B-11.06 of the Alabama Business Corporation Act (the "Alabama Act") and

hereinafter referred to as the "Merger").

         1.2     SEPARATE EXISTENCE. Without limiting the foregoing, on and
after the Merger, the separate existence of Bison/Alabama shall cease, and, in
accordance with the terms of this Agreement, the title to all property and
assets, tangible and intangible, owned by each of the Constituent Corporations
shall be vested in the Surviving Corporation without reversion or impairment;
the Surviving Corporation shall have all liabilities of each of the Constituent
Corporations; and any proceeding pending against any Constituent Corporation
may be continued as if the merger did not occur or the Surviving Corporation
may be substituted in its place.

         1.3     ACTIONS TO EFFECTUATE MERGER. Prior to and from and after the
Merger, Middle Bay and the Constituent Corporations shall take all such action
as shall be necessary or appropriate in order to fully and properly effectuate

         without any action on the part of the holder thereof, thereupon be
         converted into 1,167,556 shares of Middle Bay Common Stock, subject to
         the provisions of Section 2.2 below, the shares of Common Stock of
         Middle Bay required for such purpose being drawn from authorized but
         unissued shares of Middle Bay.

                 (b)      Each share of Bison/Alabama Common Stock outstanding
         and owned of record by Middle Bay, its sole shareholder, immediately
         prior to the Merger Date, shall become one issued share of Common
         Stock of the Surviving Corporation.

                 (c)      Middle Bay shall pay to Lett the sum of $5,900,000,

holder of an outstanding certificate or certificates representing the "old"
shares of Bison Common Stock (the "old certificates") which immediately prior
thereto represented shares of Bison Common Stock will, upon surrender of such
old certificate or certificates, be exchanged for a certificate or certificates
(the "new certificates"), which new certificate or certificates Middle Bay
agrees to provide free and clear of all liens and claims, representing the
number of shares of Middle Bay Common Stock into which the aggregate number of
shares of Bison Common Stock previously represented by such old certificate or
certificates surrendered shall have been converted pursuant to Section 2.1 of
this Agreement.

         2.3     STATUS PENDING EXCHANGE OF CERTIFICATES. Until surrendered and
exchanged, each outstanding old certificate shall be deemed for all corporate
purposes, other than the payment of dividends or liquidating or other
distributions, if any, to holders of record of Middle Bay Common Stock, to
represent the number of whole shares of Middle Bay Common Stock into and for
which the shares of Bison Common Stock theretofore represented by such old
certificate shall have been converted. No dividend or liquidating or other
distribution, if any, payable to holders of record at or after the Merger Date
of shares of Middle Bay Common Stock, or payable subsequent to the Merger to
holders of record at a time prior to the Merger of shares of Bison Common
Stock, shall be paid to the holders of outstanding old certificates; provided,
however, that upon surrender and exchange of such outstanding old certificates,
there shall be paid to the record holders of the new certificates issued in
exchange therefor the amount, without interest thereon, of dividends and
liquidating or other distributions, if any, which theretofore have become
payable to holders of record on or after the Merger Date with respect to the
number of whole shares of Middle Bay Common Stock represented by such new
certificates.

         2.4     NO TRANSFERS PENDING MERGER. As of the Merger Date, no
transfer of the shares of Bison Common Stock outstanding prior to the Merger
Date shall be made on the stock transfer books of the Surviving Corporation.
If, after the Merger Date, old certificates are presented to Middle Bay or the
Surviving Corporation, they shall be exchanged pursuant to this Article II.

         Middle Bay's common stock, including the Middle Bay Common Stock
         issuable hereunder, shall be registered pursuant to Section 12(g) of
         the 1934 Act, and Middle Bay shall have timely filed all reports with

                 (b)      Securities Laws Compliance. Middle Bay and Lett shall
         use their reasonable efforts to assure that the issuance of the Middle
         Bay Common Stock hereunder qualifies as exempt from the registration
         requirements of the Securities Act of 1993, as well as securities laws
         of such states as would apply to the issuance and delivery of the
         Middle Bay Common Stock as contemplated hereunder.

         7.2     TRANSFER RESTRICTIONS. Bison agrees that transfer of the
Middle Bay Common Stock issuable to Bison and distributed to Lett at Closing
shall be restricted for a period of 24 months from the Closing Date (the
"Restriction Period"). None of those shares may be distributed, sold or
transferred to any person during the Restriction Period. The Middle Bay shares
shall not be publicly reoffered or sold thereafter by Bison except in
compliance with Rule 144 under the 1933 Act or in transactions otherwise exempt
from registration under the 1933 Act and applicable state securities laws. Each
certificate representing such shares issued and delivered at or after Closing
shall bear an appropriate legend regarding such transfer restrictions, and such
restrictions shall be appropriately noted on the stock transfer records of
Middle Bay.

         7.3     REGISTRATION RIGHTS. Lett (and/or his successors in interest,
if any) shall have the following rights with respect to registration of the
Middle Bay Common Stock acquired hereby.

                 (a)      Piggyback Registration. If Middle Bay shall at any
         time or times determine to register under the 1933 Act any shares of
         its Common Stock (other than registration of common stock under stock
         option plans, stock ownership plans, or other employee benefit plans
         of Middle Bay or its subsidiaries) pursuant to an offering whereby
         Middle Bay will receive cash for the sale of such common stock, it
         will notify each former Bison shareholder in each case of such
         determination at least thirty (30) days prior to filing the
         registration statement and, upon the receipt of written request by
         such shareholders representing at least a majority of the Middle Bay
         Common Stock issued pursuant to the Merger given within fifteen (15)
         days after receipt of such notification, Middle Bay will use its best
         efforts to cause any of the Middle Bay Common Stock, as specified in
         such request to be registered under the 1933 Act pursuant to such
         registration statement, to the extent and under the condition that
         such registration is permissible under the 1933 Act and the rules and
         regulations thereunder; provided, however, that if the managing
         underwriter selected by Middle Bay advises Middle Bay in writing that,
         in its opinion, the inclusion of Middle Bay Common Stock requested to
         be included in such registration would materially adversely affect the
         distribution of all such common stock, then the former Bison
         shareholders shall not be permitted to register their Middle Bay
         Common Stock as specified in such request, but if such advice is not
         given at any time thereafter, both Middle Bay and the former Bison
         shareholders may sell Middle Bay Common Stock in the proposed
         distribution, with each party being entitled to sell a proportion of
         the number of shares to be sold by the former Bison shareholders and
         Middle Bay in its proposed distribution corresponding to the ratio
         that the number of shares proposed to be sold by such party bears to
         the aggregate number of shares proposed to be sold by former Bison
         shareholders and Middle Bay.

<PAGE>


                 (b)      Demand Registration. If Middle Bay shall at any time
         or times determine to register under the 1933 Act any shares of its
         common stock in connection with the acquisition of another company or
         an acquisition of assets, or if the number of Middle Bay Common Stock
         owned by Lett shall become less than ten percent (10%) of the issued
         and outstanding shares of Middle Bay Common Stock (other than as a
         consequence of the sale of Middle Bay Common Stock by Lett), it will
         notify Lett in each case of such determination at least thirty (30)
         days prior to filing the registration statement and, upon the receipt
         of Lett's written request given within fifteen (15) days after Lett's
         receipt of such notification, Middle Bay will use its best efforts to
         cause any of the Middle Bay Common Stock, as specified in such request
         to be registered under the 1933 Act pursuant to a separate
         registration statement for the purpose of permitting the sale of
         Lett's Middle Bay Common Stock in a secondary distribution, to the
         extent and under the condition that such registration is permissible
         under the 1933 Act and the rules and regulations thereunder, and to
         further use its best efforts to maintain the effectiveness of such
         registration statement (including but not limited to the filing of
         such post-effective amendments, prospectus supplements, etc.) until
         such time as Lett will be eligible to sell the Middle Bay Common Stock
         pursuant to the terms of Rule 144(k) as promulgated under the 1933
         Act. Lett's rights under this Section 7.3(b) are limited to one
         effective registration of Lett's Middle Bay Common Stock.

                 (c)      Expenses. Middle Bay shall pay all expenses incurred
         in connection with any registration pursuant to this Section 7.3,
         except that Lett and/or the other former Bison shareholders, as the
         case may be, shall pay for (i) any broker or underwriting commissions
         or discounts relating to Middle Bay Common Stock sold by such
         shareholders, and (ii) fees of counsel to such shareholders engaged
         separately from counsel to Middle Bay in connection with such
         registration.

         7.4     RESTRICTIONS ON VOTING RIGHTS. Bison and Lett agree that for a
period of 12 months following the Closing Date, voting rights with respect to
the shares of Middle Bay Common Stock issuable to Bison's shareholders
hereunder (or otherwise acquired by Lett) shall be limited as follows:

                 (a)      In connection with any vote taken or consent, wavier
         or ratification given in connection with the election or removal of
         directors of Middle Bay, Lett shall vote only that number of shares of
         Middle Bay Common Stock, regardless of any greater number of such
         shares owned by Lett or any entity controlled by Lett, in the
         aggregate, as shall represent 20% or less of the total number of
         shares of Middle Bay Common Stock issued and outstanding and eligible
         to vote at the time of any such vote, consent, waiver or ratification.

                 (b)      Each certificate representing the shares of Middle
         Bay Common Stock issuable to the Bison shareholders hereunder and
         delivered at Closing shall bear an appropriate legend regarding such
         voting restrictions, and such restrictions shall be appropriately
         noted on the stock transfer records of Middle Bay.

<PAGE>


                 (c)      For purposes of this Section 7.4, the number of
         shares of Middle Bay Common Stock owned by the former Bison
         shareholders shall include any shares of Middle Bay Common Stock
         presently owned by Bison or hereafter issued or distributed to any
         present shareholder of Bison.

                 (d)      In the event all or a portion of the Kaiser-Francis
         Preferred Shares or any preferred shares issued by Middle Bay to any
         other person are converted into Middle Bay Common Stock prior to 12
         months from the Closing Date specified herein, the voting restrictions
         provided in this Section 7.4 shall be removed share-for-share with
         the conversion of the Kaiser-Francis Preferred Shares or other
         preferred shares (e.g., if Kaiser-Francis converts a portion of its
         Preferred Shares into 100,000 shares of common stock, the number of
         aggregate shares of Middle Bay Common Stock which may be voted by Lett
         hereunder shall be increased by 100,000 shares).

                 (e)      If Middle Bay issues additional shares of common
         stock as part of another merger or asset acquisition transaction
         following the Closing Date and any such merger or acquisition involves
         the issuance of Middle Bay Common Stock representing, after issuance,
         more than 20% of the then outstanding shares of Middle Bay Common
         Stock, if such shares are not made subject to voting restrictions
         substantially identical to those imposed by this Section 7.4, this
         Section 7.4 shall thereafter no longer apply.

                                  ARTICLE VIII
                  MIDDLE BAY'S REPRESENTATIONS AND WARRANTIES

         9.6     CONDITION OF TANGIBLE ASSETS. All buildings, structures,
facilities, equipment and other material items of tangible property and assets
constituting the properties of Bison are in good operating condition and
repair, subject to normal wear and maintenance, are usable in the regular and
ordinary course of business and, to Lett's and Bison's knowledge, conform to
all applicable laws, ordinances, codes, rules and regulations relating to their
construction, use and operation. No person other than Bison owns any equipment

         9.7     FINANCIAL STATEMENTS. Attached hereto as Exhibit "D" are

accepted accounting principles, will not reflect material adverse changes in
assets, liabilities or results of operations. At December 31, 1996, Bison had
no material liabilities of any nature, direct or indirect, fixed or contingent,
which were not reflected on the Financial Statements, including, without
limitation, a $40,000 accrual for potential income tax liability arising out of
an audit by the Internal Revenue Service of Bison's tax return for the year
ended March 31, 1993.

         9.8     LITIGATION. Except as disclosed in Schedule "9.8" attached
hereto, there are no claims, causes of action, third-party claims, actions,
proceedings, investigations or orders, judgments or decrees, including
administrative proceedings (matured, unmatured, asserted or unasserted),
against or involving Bison or Lett pending or, to the best of Bison's and
Lett's knowledge, threatened before any court or governmental agency that
question the validity of this Agreement or the transactions contemplated by
this Agreement or any action taken or to be taken in connection therewith or
herewith. Except as set forth on Schedule "9.8" in respect to Bison or Lett,
there are no actions, proceedings or investigations pending (or, to Bison's or
Lett's knowledge, any basis therefor or threat thereof) which, either in any
case or in the aggregate, would, if adversely determined, result in any adverse
effect on the business, prospects, conditions, affairs or operations of Bison
of its properties.

         9.9     EMPLOYEES. Bison has no employment contracts, collective
bargaining agreements or any labor trouble, EEOC claims, OSHA citations or any
workers' compensation claims, controversies or other claims on unsettled
grievances pending or, to the knowledge of Bison, threatened by any of its
officers, agents, employees or any other third party involved in the operations
of Bison, or collective bargaining organizations or pension, 401(k), stock
bonus, profit sharing, stock option or other agreements providing for
remuneration or benefits to its officers, directors or employees, except as set
forth on Schedule "9.9" attached hereto. Bison





                                     - 13 -

<PAGE>

is, to its knowledge, in compliance in all material respects with the
requirements of the Employee Retirement Income Security Act of 1974, as
amended.

         9.10    ENVIRONMENTAL MATTERS. To the best of its and Lett's
knowledge, Bison is not aware of, nor has Bison received notice of, any past,
present or future events, conditions, circumstances, activities, practices,
instances, actions or plans which may interfere with or prevent compliance or
continue compliance with those laws or any regulation, code, plan, order,
decree, judgment, injunction, notice or demand letter issued, entered,
promulgated or approved thereunder or which may give rise to any common law or
legal liability or otherwise form the basis of any claim, action, demand, suit,
proceeding, hearing, study or investigation based on or related to the
violation by Bison of applicable Environmental Laws. With the exception of the
foregoing representations and warranties as to "knowledge," neither Bison nor
Lett makes any representations or warranties, either express or implied, or
otherwise, on any environmental matters, including without limitation, the
violation of any federal, state, local, municipal law, rule or regulation
relating to the environment or natural resource (collectively, "Environmental
Laws") by Bison and makes no warranty or representation, express or implied or
otherwise, with respect to the accuracy or completeness of any information,
records or data made available to Middle Bay in connection with this Agreement.
Except for a breach of the foregoing representations and warranties as to
"knowledge," Middle Bay is acquiring, pursuant to the Merger, the properties
"AS IS" with all environmental defects, if any, including those matters
described in Schedule "9.10", and has relied upon Middle Bay's own
investigation and analysis to enter into this Agreement and consummate the
transactions set forth herein. Middle Bay agrees that Bison and its current, as
of the Merger Date, employees, officers, directors, shareholders,
representatives and agents, except for breach of any representation and
warranty herein, are hereby released and held harmless by Middle Bay and shall
not be responsible or liable to Middle Bay for any claims, costs, losses,
liabilities, judgments, demands, tort claims, damages, expenses, demands,
actions or causes of action arising from environmental matters or violations of
Environmental Laws arising from or relating to any of Bison's properties.

         9.11    COMPLETENESS OF DISCLOSURE. No representation or warranty by
Bison or Lett in this Agreement nor any certificate, statement, document or
instrument furnished or to be furnished to Middle Bay pursuant hereto, or in
connection with the negotiation, execution, performance of or the obtaining of
consents of shareholders of Bison to this Agreement, contains or will contain
any untrue statement of a material fact or omits or will omit to state a
material fact required to be stated herein or therein or necessary to make any
statement herein or therein not misleading.

         9.12    GAS IMBALANCES. Bison has received no deficiency payments
under any gas contracts for which any party has a right to take deficiency gas,
nor has Bison received any payments for production which are subject to refund
or recoupment out of future production.

         9.13    WELL STATUS. Bison has no outstanding accounts payable arising
out of an authority for expenditure or other similar invoice to plug and
abandon any well or wells because the well or wells are not





                                     - 14 -

<PAGE>

capable of producing in commercial quantities. All wells drilled, completed,
operated, plugged or abandoned by Bison on or related to its properties have
been drilled, completed, operated, plugged or abandoned in accordance and
compliance with all operating agreements, other contracts or agreements, laws,
rules, regulations, permits, orders, judgments and decrees of any court or
governmental body or agency relating thereto and within the boundaries
specified therein or otherwise permitted by law; and Bison has not received any
notice or other indication to the contrary.

         9.14    INCOME TAX CONSEQUENCES. Any contrary provision contained in
this Agreement (or any other agreement or communication) notwithstanding,
neither Bison nor Lett is relying upon any statement made by or advice provided
by Middle Bay regarding the income tax consequences of the Merger or other
transactions contemplated by this Agreement, as to Bison or as to any of the
Bison shareholders. The parties understand that such transaction will result in
recognition of gain or loss for federal income tax purposes by the Bison
shareholders relative to their allocated portions of the cash price. Bison and
Lett shall rely solely upon their tax advisors with respect to such tax
consequences and the tax consequences to the other Bison shareholders.

         9.15    RESERVE REPORT. The engineering report set forth in Exhibit
"B" was prepared by Middle Bay's professional staff. Bison provided information
to Middle Bay which Bison believes to be true and correct and upon which Middle
Bay has relied in the preparation of the report. The reserves included in the
report are estimates only and should not be construed as being exact
quantities. They may or may not be actually recovered, and, if recovered, the
revenues therefrom and the actual costs related thereto could be more or less
than the estimated amounts. Moreover, estimates of the reserves may increase or
decrease as a result of future operations.

                                   ARTICLE X
                             MIDDLE BAY'S COVENANTS

         Middle Bay covenants and agrees that, pending the Closing and as the
context requires, following Closing, except as otherwise agreed to in writing
by Bison:

         10.1    BUSINESS IN THE ORDINARY COURSE. Middle Bay's business shall
be conducted solely in the ordinary course consistent with past practice, and
except for actions necessary for its due organization, Bison/Alabama shall
engage in no business pending Closing.

         10.2    CONDUCT OF BUSINESS. Middle Bay shall use its best efforts to
conduct its business in such a manner that, on the Closing Date, the
representations and warranties of Middle Bay contained in this Agreement shall
be true, except as specifically contemplated by this Article X as though such
representations and warranties were made on and as of such date. Furthermore,
Middle Bay shall cooperate with Bison and





                                     - 15 -

<PAGE>

use its best efforts to cause all of the conditions to the obligations of
Middle Bay under this Agreement to be satisfied on or prior to the Closing
Date.

         10.3    UPDATE DISCLOSURES. Middle Bay shall promptly disclose to
Bison and Lett any material changes in its reserves or business prior to the
Closing Date, as well as any information contained in its representations and
warranties which, because of an event occurring after the date hereof, or the
discovery of an event occurring or having occurred at any time, is incomplete
or is no longer correct as of all times after the date hereof until the Closing
Date; provided, however, that none of such disclosures shall be deemed to
modify, amend or supplement the representations and warranties of Middle Bay

(by Notice).

         10.4    COMPLIANCE WITH LAWS. Middle Bay shall comply with all laws,
ordinances, rules, regulations and orders applicable to its business or
operations, assets or properties in respect thereof, the noncompliance with

was out of the ordinary.

annual basis. The amount of square footage leased will be determined by Middle
Bay at a cost equal to the average rental rates for the area.

operations in the Headquarter's Office for a period of six months following the

"Prospects") developed by Bison, Dean Pattisson or Whitsunday Enterprises, LLC
("Whitsunday"). In connection with the Prospects, Middle Bay and Bison
acknowledge and agree that Whitsunday will receive a ten percent (10%) carried
working interest (at no cost to Whitsunday) in each of the Prospects. Middle
Bay and Bison further acknowledge and agree that Clinton Enterprises, L.L.C.
will receive an overriding royalty interest in each of the Prospects not to
exceed a percentage that delivers an eighty percent (80%) net revenue interest
on each of the Prospects to either Middle Bay or Bison.. If at least 24 of the
Prospects are not drilled by Middle Bay or Bison during the Development Period,
any undeveloped oil and gas leases owned by Bison at the Closing Date or
acquired within 12 months following the Closing Date, which are not otherwise
held by production and not previously drilled by Middle Bay or Bison, shall be
transferred to Whitsunday within thirty (30) days of the expiration of the
Development Period.

promptly disclose to Middle Bay any information contained in its
representations and warranties which, because of an event occurring after the
date hereof, or the discovery of an event occurring or having occurred at any
time, is incomplete or is no longer correct as of all times after the date

records and information with respect to the affairs of Bison and its business
and copies of any working papers relating thereto as Middle Bay shall from time

partnership, corporation, association or other person, the business of which is
competitive with (or otherwise engaged in competition with) the current
business of Bison or the business of Middle Bay, as described in Paragraph A
hereof under "Background and Purpose," derived or contemplated at the Closing,
all of the foregoing within the United States.

         operations of Bison shall have the values set forth in Exhibit "B"

                 (b)      Compliance With this Agreement. Middle Bay shall have
         performed and complied with all agreements and conditions required by
         this Agreement to be performed or complied with by it prior to or at

                 (c)      Closing Certificates. Bison shall have received a

                 (f)      Approval of Counsel; Corporate Matters. All actions,
         proceedings, resolutions, instruments and documents required to carry
         out this Agreement or incidental hereto and all other related legal

                                INDEMNIFICATION

         13.1    GENERAL INDEMNIFICATION OBLIGATION OF LETT. From and after the
Closing, Lett shall reimburse, indemnify and hold Middle Bay harmless against
and in respect of:

                 (a)      any and all damages, losses, deficiencies,
         liabilities, costs and expenses incurred or suffered by Middle Bay
         that result from, relate to or arise out of any material
         misrepresentation, material breach of warranty or material
         nonfulfillment of any material agreement or covenant on the part of
         Bison or Lett under this Agreement, or any material misrepresentation
         in or material omission from any certificate, statement, document or
         instrument furnished to Middle Bay pursuant to or in connection with
         negotiation, execution or performance of this Agreement; and

                 (b)      any and all actions, suits, claims, proceedings,
         investigations, demands, assessments, audits, fines, judgments, costs
         and other expenses (including, without limitation, reasonable legal
         fees and expenses) incident to any of the foregoing or to the
         enforcement of this Section 13.1.

         13.2    GENERAL INDEMNIFICATION OBLIGATION OF MIDDLE BAY. From and
after the Closing, Middle Bay will reimburse, indemnify and hold Lett harmless

         13.3    METHOD OF ASSERTING CLAIMS, ETC. In the event that any claim
or demand for which Lett would be liable to Middle Bay hereunder is asserted
against or sought to be collected from Middle Bay by a third party, Middle Bay
shall promptly notify Lett of such claim or demand, specifying the nature of
such claim or demand and the amount or the estimated amount thereof to the
extent then feasible (which estimate shall not be conclusive of the final
amount of such claim and demand) (the "Claim Notice"). Lett shall then have
fifteen (15) days from the date of receipt by Lett of the Claim Notice (the
"Notice Period") to notify Middle Bay (i) whether or not he disputes his
liability to Middle Bay hereunder with respect to such claim or demand and (ii)
notwithstanding any such dispute, whether or not he desires, at Lett's sole
cost and expense, to defend Middle Bay against such claim or demand.

                 (a)      If Lett disputes his liability with respect to such
         claim or demand or the amount thereof (whether or not Lett desires to
         defend Middle Bay against such claim or demand as provided in
         subsections 13.3(b) and 13.3(c) below), such dispute shall be resolved
         in accordance with Section 13.5. Pending the resolution of any dispute
         by Lett of his liability with respect to any claim or demand, such
         claim or demand shall not be settled without the prior written consent
         of Middle Bay (given by Notice).

                 (b)      In the event that Lett notifies Middle Bay within the
         Notice Period that he desires to defend Middle Bay against such claim
         or demand, then, except as hereinafter provided, Lett shall have the
         right to defend Middle Bay by appropriate proceedings, which
         proceedings shall be promptly settled or prosecuted by Lett to a final
         conclusion in such manner as to avoid any risk of Middle Bay's
         becoming subject to liability for any other matter; provided, however,
         Lett shall not, without the prior written consent of Middle Bay (given
         by Notice), consent to the entry of any judgment against Middle Bay or
         enter into any settlement or compromise which does not include, as an
         unconditional term thereof, the giving by the claimant or plaintiff to
         Middle Bay of a release, in form and substance satisfactory to Middle
         Bay's counsel, from all liability in respect of such claim or
         litigation. If Middle Bay desires to participate in, but not control,
         any such defense or settlement, it may do so at its sole cost and
         expense. If, in the reasonable opinion of Middle Bay, any such claim
         or demand or the litigation or resolution of any such claim or demand
         involves an issue or matter which could have a materially adverse
         affect on the business, operations, assets, properties or prospects of
         Middle Bay, including, without limitation, the administration of the
         tax returns and responsibilities under the tax laws of Middle Bay,
         then Middle Bay shall have the right to control the defense or
         settlement of any such claim or demand, and its reasonable costs and
         expenses shall be included as part of the indemnification obligation
         of Lett hereunder; provided, however, that Middle Bay shall not settle
         any such claim or demand without the prior written consent (given by
         Notice) of Lett, which consent shall not be unreasonably withheld. If
         Middle Bay should elect to exercise such right, Lett shall have the
         right to participate in, but not control, the defense or settlement of
         such claim or demand, at his sole cost and expense.

<PAGE>


                 (c)      If Lett elects not to defend Middle Bay against such
         claim or demand, whether by not giving Middle Bay timely Notice as
         provided above or otherwise, then the amount of any such claim or
         demand, or if the same be defended by Lett or by Middle Bay (but
         Middle Bay shall have no obligation to defend any such claim or
         demand) then that portion thereof as to which such defense is
         unsuccessful, in each case shall be conclusively deemed to be the
         liability of Lett hereunder, unless Lett shall have disputed his
         liability to Middle Bay hereunder, as provided in Section 13.5 hereof.

                 (d)      If Middle Bay should have a claim against Lett
         hereunder that does not involve a claim or demand being asserted
         against or sought to be collected from it by a third party, Middle Bay
         shall, within a reasonable time after discovery of such claim, send a
         Claim Notice with respect to such claim to Lett. If Lett disputes his
         liability with respect to such claim or demand, such dispute shall be
         resolved in accordance with Section 13.5 hereof; if Lett fails to
         notify Middle Bay within the Notice Period that he disputes such
         claim, the amount of such claim shall be conclusively deemed the
         undisputed liability of Lett hereunder.

                 (e)      All claims for indemnification by Lett under this
         Agreement shall be asserted and resolved under the procedures set
         forth above, substituting in the appropriate place "Lett" for "Middle
         Bay" and "Middle Bay" for "Lett" (and variations thereof).

         13.4    PAYMENT. Upon determination of the liability under Section
13.3 or 13.5 hereof, the appropriate party shall pay to the other, as the case
may be, within ten (10) days after such determination, the amount of any claim
for indemnification made hereunder.

         13.5    ARBITRATION.

                 (a)      All disputes under this Article XIII shall be settled
         by arbitration in Mobile, Alabama or in the state where Middle Bay's
         corporate headquarters is located at the time of such arbitration,
         before a single arbitrator pursuant to the rules of the American
         Arbitration Association. Arbitration may be commenced at any time by
         any party hereto giving Notice to each other party to a dispute that
         such dispute has been referred to arbitration under this Section 13.5.
         The arbitrator shall be selected by the joint agreement of Lett and
         Middle Bay, but if they do not so agree within twenty (20) days after
         the date of the Notice referred to above, the selection shall be made
         pursuant to the rules from the panels of arbitrators maintained by
         such Association.  Any award rendered by the arbitrator shall be
         conclusive and binding upon the parties hereto. Any such award shall
         be accompanied by a written opinion of the arbitrator, giving the
         reasons for the award. This provision for arbitration shall be
         specifically enforceable by the parties, and the decision of the
         arbitrator in accordance herewith shall be final and binding, and
         there shall be no right of appeal therefrom. Each party shall pay its
         own expenses of arbitration, and the expenses of the arbitrator shall
         be equally shared; provided, however, that if in the opinion of the
         arbitrator any claim for indemnification or any defense or objection
         thereto





                                     - 23 -

<PAGE>

         was unreasonable, the arbitrator may assess, as part of his award, all
         or any part of the arbitration expenses of the other party (including
         reasonable attorneys' fees) and of the arbitrator against the party
         raising such unreasonable claim, defense or objection.

                 (b)      To the extent that arbitration may not be legally
         permitted or required hereunder and the parties to any dispute
         hereunder may not at the time of such dispute mutually agree to submit
         such dispute to arbitration, any party may commence a civil action in
         a court of competent jurisdiction to resolve disputes hereunder and to
         seek any appropriate remedy. Nothing contained in this Section 13.5
         shall prevent the parties from settling any dispute by mutual
         agreement at any time.

         13.6    OTHER RIGHTS AND REMEDIES NOT AFFECTED. The indemnification
rights of the parties under this Article XIII are independent of and in
addition to such rights and remedies as the parties may have at law or in
equity or otherwise for any misrepresentation, breach of warranty or failure to
fulfill any agreement or covenant hereunder on the part of any party hereto,
including without limitation the right to seek specific performance, rescission
or restitution, none of which rights or remedies shall be affected or
diminished hereby.

         13.7    LIMITATION ON INDEMNIFICATION BY LETT. The indemnification by
Lett, pursuant to this Article XIII, shall be limited to (i) a term of two (2)
years from the Closing Date at which time Lett's indemnity under this Article
XIII will terminate and Lett will have no further liability thereunder; and

Stock, to be credited against Lett's obligations hereunder at an amount equal
to seventy-five percent (75%) of the prior twenty (20) days' average market
price for such Middle Bay Common Stock from the date of the Claim Notice. To
the extent Lett has sold or transferred Middle Bay Common Stock and the number
of shares of Middle Bay Common Stock owned by him at the time of
indemnification is inadequate to satisfy such indemnification, then Lett shall
be liable for the remainder of such indemnification in an amount not to exceed
the lesser of (a) the consideration received by Lett for the Middle Bay Common
Stock so previously transferred or sold (which consideration shall be for an
amount no less than seventy-five percent (75%) of the prior twenty (20) days'

otherwise engaged in any conduct giving rise to any right to earn any

the one hand, and Bison and Lett, on the other hand, agree to indemnify and
hold the other harmless in accordance with Article XIII from any loss or

         termination at any time before Closing as follows:

                          (i)     by mutual consent of Bison and Middle Bay; or

                          (ii)    by Middle Bay at any time if the
                 representations and warranties of Bison or Lett contained in
                 Article IX were incorrect in any material respect when made or
                 at any time thereafter; or

                          (iii)   by Bison and Lett acting together at any time
                 if the representations and warranties of Middle Bay contained
                 in Article VIII were incorrect in any material respect when
                 made or at any time thereafter; or

                          (iv)    by any nonbreaching party if Closing fails to
                 occur on or before February 28, 1997 or such later date to
                 which the parties reasonably agree.

         Such termination shall be effective upon the effective date of such
Notice.

                 (b)      In the event of termination pursuant to the
         provisions of this Section 17.15, this Agreement shall have no further
         force or effect, and no party shall have any liability to any of the
         other parties in respect of this Agreement, unless the termination was
         prompted by any material misrepresentation, breach of warranty or
         breach of covenant or other agreement by any party, in which event
         such party shall be liable to the other party for all costs and
         expenses of the other party in connection with the preparation,
         negotiation, execution and performance of this Agreement.

                 (c)      The provisions of this Section 17.15 are not intended
         to provide an exclusive remedy for any party's misrepresentation,
         breach of warranty, breach of covenant or other default. Any party may
         elect to enforce its rights under this Agreement, by seeking any
         remedy available at law or in





                                     - 28 -

         equity (including specific performance), instead of electing to
         terminate this Agreement pursuant to this Section 17.15. The
         provisions of this Section 17.15 are intended to provide the exclusive
         remedy for failure of any contingency or condition precedent described
         in this Agreement, except to the extent that such failure results from
         misrepresentation, breach of warranty, breach of covenant or other
         default by any party.
