ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA INFORMATION, AND EXHIBITS

 
         (B)      PRO FORMA FINANCIAL INFORMATION
 
                          MIDDLE BAY OIL COMPANY, INC.
               Unaudited Condensed Pro Forma Financial Statements

As  discussed  in Item 2 of Form 8-K filed with the  commission  on May 5, 1998,
Middle Bay Oil Company,  Inc, ("Middle Bay") closed an Asset Purchase  Agreement
(the "Agreement") on April 16, 1998, with Service Drilling Co., L.L.C. ("Service
Drilling")  and certain of its  affiliates , whereby  Middle Bay acquired all of
the assets of Service  Drilling  and its  affiliates  in exchange for Middle Bay
common stock and cash.

Service  Drilling and its  affiliates are  privately-owned  domestic oil and gas
development and production  companies with assets located  primarily in Oklahoma
and the Texas  Panhandle.  Pursuant to the Agreement,  Middle Bay issued 666,000
shares  of its  common  stock  and  paid  an  aggregate  cash  consideration  of
$6,500,000, subject to post-closing adjustments, in exchange for the assets. The
economic  effective date of this transaction is March 1, 1998. Asset values were
determined by estimating the discounted reserve value of the acquired properties
and through negotiation. The cash portion of the consideration is being financed
through Middle Bay's credit facility with Compass Bank and from cash on hand.

The  following  pro forma data  presents the results of the Company for the year
ended December 31, 1997 and for the three months ended March 31, 1998, as if the
Service  Drilling  acquisition  had  occurred on January 1, 1997.  The pro forma
financial  statements  are also  based,  in part,  on the  historical  financial
statements of Enex Resources Corporation  ("Enex"),  Shore Oil Company ("Shore")
and Bison Energy Corp.  ("Bison").  Middle Bay acquired  79.2% of Enex effective
March  27,  1998,  100% of  Shore  effective  June  30,  1997  and 100% of Bison
effective February 28, 1997. Such historical  financial  statements for the Enex
merger are  included in the Form 8-K filed by Middle Bay on May 6, 1998 and such
historical  financial  statements  for the Shore merger are included in the Form
8-K/A filed by Middle Bay on  September  3. 1997 and such  historical  financial
statements  for the Bison  merger are included in the Form 8-K/A filed by Middle
Bay on April 25, 1997.

The Pro Forma  Condensed  Statements  of  Operations  for the three months ended
March 31,  1998 and for the year  ended  December  31,  1997 have been  prepared
assuming  the merger  had been  consummated  on  January 1, 1997.  The Pro Forma
Consolidated  Balance  Sheet has been  prepared  assuming  the  merger  had been
consummated on March 31, 1998.

The proforma  results are  presented for  comparative  purposes only and are not
necessarily  indicative  of the results  which would have been  obtained had the
acquisition been consummated as presented. The following data reflects pro forma
adjustments  for  oil and  gas  revenues,  production  costs,  depreciation  and
depletion  related to the  properties  and  business  acquired,  and the related
income tax effects.  The  unaudited  condensed  pro forma  financial  statements
should be read in conjunction with the notes thereto.

MIDDLE BAY OIL COMPANY, INC.
Notes to Unaudited Condensed Pro Forma Financial Statements

Note A - Pro Forma Adjustments for Bison and Shore Mergers

     On February 10, 1997,  Middle Bay and Bison entered into a Merger Agreement
whereby  Bison was merged into Middle Bay,  effective  February  28,  1997.  The
merger was accounted for using the purchase method of accounting.  In completing
the merger, Middle Bay issued 605,556 shares of Middle Bay common stock and paid
$6,654,114  in cash in  exchange  for all of the  issued and  outstanding  Bison
common stock.

     On June 20,  1997,  Middle Bay and Shore  entered  into a Merger  Agreement
whereby Shore was merged into Middle Bay effective June 30, 1997. The merger was
accounted for using the purchase method of accounting.  In completing the merger
Middle Bay issued 1,883,333 shares of Middle Bay common stock, 266,667 shares of
Middle Bay Series B  convertible  preferred  stock and paid  $200,000 in cash in
exchange for all of the issued and  outstanding  Shore common stock.  Middle Bay
also paid Shore's  indebtedness  to its  shareholders  of $2,333,303 and assumed
bank debt of Shore amounting to $2,105,000.

     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 were  allocated  to assets and  liabilities  acquired
based on estimated fair values.

     Middle  Bay  incurred  approximately  $35,000  and  $38,000  in  legal  and
accounting expenses related to the Bison and Shore mergers, respectively,  which
were included as a cost of the merger. 

     The accompanying Pro Forma Combined Condensed  Statements of Operations for
the year ended  December  31, 1997 and for the three months ended March 31, 1998
have been  prepared as if the Bison and Shore mergers had occurred on January 1,
1997 and reflect the following adjustments:

     (1) To adjust depletion,  depreciation and amortization  expense to reflect
Middle Bay's purchase price  allocated to property and equipment  using the unit
of production method utilized by Middle Bay.

     (2) To record the preferred  stock  dividends  paid on the preferred  stock
issued for the cash portion of the Bison purchase price and issuded in the Shore
purchase price.

     (3) To record the reduction in interest expense on the debt retired.

     (4) To adjust the  provision  for income  taxes for the change in financial
taxable income as a result of the mergers.

     (5) To reflect the impact on the weighted average common shares outstanding
for the issuance of 2,488,889  shares of Middle Bay common stock in  conjunction
with the Bison and Shore mergers.





     (6) To remove management income for accounting and administrative functions
performed by Bison for other entities. Subsequent to the merger, Bison no longer
performed such functions.

     (7) To remove  equity in net  earnings  of equity  investees  that were not
purchased.

     (8) To reflect the issuance of 388,884 shares of Series A Preferred  Stock,
266,667 Shares of Series B Preferred Stock and,  2,488,889  shares of Middle Bay
common stock in conjunction  with the Bison and Shore  mergers.  Pro Forma basic
net income  (loss) per common  share  information  is computed  by dividing  net
income (loss),  adjusted for the preferred stock dividend requirement of $93,332
for the six months ended June 30, 1997 by the Pro Forma weighted  average common
shares outstanding. Shares issuable upon exercise of options and upon conversion
of preferred  stock are included in the  computations  of the pro forma dilutive
income per common and common equivalent shares if the effect is dilutive.

Note B - Pro Forma Adjustments for Purchase of Enex

     Middle Bay Oil Company,  Inc, acquired on March 27, 1998,  1,064,432 shares
of the common stock of Enex Resources Corporation,  a Delaware corporation,  for
$15,966,480  or $15 per share pursuant to Middle Bay's tender offer (the "tender
offer") which began on February 19, 1998. The Enex shares acquired by Middle Bay
represent 79.2% of the total outstanding Enex common shares. Enex is the general
partner of Enex Consolidated  Partners,  L.P., a New Jersey Limited  Partnership
whose  principal  business is oil and gas  production.  Enex's  general  partner
interest is 4.1%.  Enex also owns an approximate 55% interest in the partnership
as a limited partner.

     The cost of  allocating  the  purchase  of Enex  was  allocated  using  the
purchase  method of  accounting  based upon the fair value of the  consolidating
assets and  liabilities of Enex with the remaining  purchase price  allocated to
oil and gas  properties.  The  allocation of the purchase price is summarized as
follows: (in thousands)

         Working capital...........................   $       4,812
         Oil and gas properties..................            18,821
         Minority Interest..........................         (7,667)
                                                            --------
                                                      $      15,966

     The total cost of the purchase was $15.966 million. The cash portion of the
cost was $1.5 million with the  remaining  $14.466  million  derived from Middle
Bay's line of credit, which has a stated interest rate of LIBOR plus 2%.

     The accompanying Pro Forma Combined Condensed  Statements of Operations for
the year ended  December  31, 1997 and for the three months ended March 31, 1998
have been  prepared as if the Enex  purchase had occurred on January 1, 1997 and
reflect the following adjustments:



     (9) To adjust depletion,  depreciation, and amortization to reflect Middle
Bay's  purchase price  allocated to property and equipment  using the production
method utilized by Middle Bay.


     (10) To recognize the additional  interest expense resulting from a $15.012
million loan against Middle Bay's line of credit at LIBOR plus 2%.

     (11) Middle Bay's 79.2% ownership of Enex will not permit  consolidation of
Enex with MIddle Bay for tax reporting purposes.

     (12) To recognize  the portion of Enex's  income/loss  attributable  to the
minority interest shareholders in Enex.
