                                    PART I.

ITEM 1.   DESCRIPTION OF BUSINESS

  Midland Resources, Inc., a Texas corporation, (the "Company", which reference
shall include the Company's wholly owned subsidiaries), is an independent oil
and gas company engaged primarily in the exploration and development of domestic
oil and gas.  The Company, incorporated June 5, 1989, was organized in 1990 with
the issue of common stock and warrants in exchange for the partnership interests
of seven former public oil and gas limited partnerships.

  The Company's initial emphasis was on acquisition and exploitation of oil 
and gas properties.  In 1995, the Company changed its emphasis to 
exploration, utilizing three dimensional ("3D") seismic technology.

  On December 20, 1996, the Company completed the acquisition of Summit
Petroleum Corporation, an affiliate, for cash.  (See NOTE F. RELATED PARTIES, to
Consolidated Financial Statements)

  Although the Company's principal properties are located in Texas, the Company
also owns working interest and minor royalty leasehold interests in developed
and undeveloped oil and gas acreage in Illinois and Colorado.

REGULATION

  The Company's exploration, production and marketing operations are regulated
at the federal, state and local levels.  Oil and gas exploration, development
and production activities are subject to various laws and regulations governing
a wide variety of matters.  For example, there are statutes or regulations
addressing conservation practices and the protection of correlative rights, and
such regulations may affect the Company's operations and limit the quantity of
oil or gas that the Company may produce and sell.  Other regulated matters
include marketing, transportation and valuation of royalty payments.

  Among other regulatory matters at the federal level, the Federal Energy
Regulatory Commission ("FERC") regulates interstate transportation of natural
gas under the Natural Gas Act.  The Company's gas sales are not subject to
price controls but are affected by regulation of intrastate and interstate gas
transportation.  In an attempt to promote competition, the FERC has issued a
series of orders which have altered significantly the marketing and
transportation of natural gas.  To date, the Company has not experienced any
material adverse effect on gas marketing as a result of these FERC orders.
However, the Company cannot predict what effect these or subsequent regulations
may have on its future gas marketing.

                                     -1-

<PAGE>

ENVIRONMENTAL

  As an owner and operator of oil and gas properties, the Company is
additionally subject to various federal, state and local environmental
regulations, including air and water quality control laws.  These laws and
regulations may, among other things, impose liability on the lessee under an oil
and gas lease for the cost of pollution clean-up resulting from operations,
subject the lessee to liability for pollution damages, and require suspension or
cessation of operations in affected areas and impose restrictions on the
injection of liquids into subsurface aquifers that may contaminate groundwater.
Although the Company believes that it is in substantial compliance with existing
applicable environmental laws and regulations, there can be no assurance that
substantial costs for compliance will not be incurred in the future.  Moreover,
it is possible that other developments, such as stricter environmental laws,
regulations and enforcement policies thereunder, could result in additional,
presently unquantifiable, costs or liabilities to the Company.  Costs associated
with compliance with such laws have not been a material factor in the Company's
operations.

COMPETITION

  The oil and gas industry is highly competitive.  Competition for the sale of
oil and gas is principally related to pricing as it is affected by quality and
transportation costs.  The price for oil and gas is widely followed and is
generally subject to worldwide market factors.  Competition to acquire oil and
gas leases is significant and the Company will be competing with  major oil and
gas companies which have significantly greater resources.

MAJOR CUSTOMERS

  The Company had sales to the following companies that amounted to 10% or more
of revenues:

    Conoco, Inc.                           -     12%     -
</TABLE>

  Because of the ready market for its oil and gas, the Company does not consider
itself dependent on any single customer or group of customers.

INSURANCE

  The Company maintains insurance customary for operations of a similar nature.
No loss of production coverage has been sought.

                                    -2-

EMPLOYEES

  On March 16, 1998, the Company had 19 full-time employees, none of which are
subject to collective bargaining arrangements.  From time to time, the Company
utilizes the services of independent contractors to perform various field and
administrative services.  Experienced personnel are available in all disciplines
should the need to hire additional staff arise.

OFFICE FACILITIES

  In 1997, the Company moved its executive offices to 616 F.M. 1960 West, Suite
600, Houston, Texas 77090.  The Company believes that its facilities are
adequate for its current needs.

GULF COAST REGION, TEXAS

COPANO BAY 3D SEISMIC EXPLORATION AND DEVELOPMENT PROJECT

  The Copano Bay property is located in Aransas County, Texas, approximately 50
miles northeast of Corpus Christi.  The leasehold encompasses 2,355 gross acres
and currently has eight gross producing wells.  At the time the Company acquired
Copano Bay in 1991, it was producing approximately 65 BOPD and 465 MCFD.  The 
Company conducted several workovers, recompletions and re-entries, and 
increased production to average 52 BOPD and 828 MCFD in 1996 and 54 BOPD and 
729 MCFD in 1997.  During 1995, 1996 and 1997, Copano Bay properties 
accounted for approximately  9%, 5%  and 6%, respectively, of the Company's 
total oil production and approximately 28%, 16% and 16%, respectively, of the 
Company's total gas production.

  Effective June 1, 1996, the Company acquired an additional 5% working interest
in this property for approximately $177,000, and now owns approximately 68% of
the working interest in this property.

  In 1997, a 3D seismic survey was conducted covering a portion of Company owned
acreage and, in the beginning of 1998, a second 3D seismic survey was conducted
covering the remainder of the acreage.  Both seismic surveys were conducted at
no cost to the Company and the survey data is currently being processed.  When
processing is completed, the Company will be allowed to review the data to
determine if any of the data is of any value to the Company.  If the Company
determines this data has any value, the Company will be allowed to purchase the
data.

PERMIAN BASIN REGION, TEXAS

CHALK MOUNTAIN 3D SEISMIC EXPLORATION AND DEVELOPMENT PROJECT

  The Company held acreage adjoining a project generated by Texland Oil & Gas
Co. as a 3D seismic exploration project in July 1996 in Sterling, Tom Green and
Reagan Counties, Texas.  The Company has acquired a 52.75% working interest in
approximately 3,300 acres in this project.  During 1997, the Company invested

                                    -4-
<PAGE>

approximately $2,000,000 in acquisition costs and drilling of three exploratory
wells and one development well in this project.  One of these wells was
successful in the Fusselman formation.  One of the wells established production
in the Canyon formation, but due to low production volume, additional Canyon
wells are not economically justified.  Two of these wells were dry holes.  In
the first quarter of 1998, the Company acquired additional acreage in the
project based on review of 3-D seismic data.

LATIGO 3D SEISMIC EXPLORATION AND DEVELOPMENT PROJECT

  This project was defined and acquired as a 3D seismic exploration project in
1995 in the Northwest Shelf area of the Permian Basin in Hockley County, Texas.
The seismic survey covered 12 square miles and resulted in the leasing of
approximately 4,700 acres.  Two successful exploratory wells were drilled in
this project in 1997 at a cost to the Company of approximately $1,568,000.
Average daily production from the discoveries drilled in this project in 1997
was 163 BOPD.  The Company owns a 55% working interest in this project.

SUNBURST 3D SEISMIC EXPLORATION AND DEVELOPMENT PROJECT

  The Sunburst project was acquired as a 3D seismic exploration project in 1995
in the Northwest Shelf area of the Permian Basin in Terry County, Texas.  The
prospect was defined with a 14 square mile seismic survey and resulted in the
leasing of approximately 3,640 acres.  In 1996, two exploratory wells were
drilled in this project at a cost to the Company of approximately $660,000, 
with one completed in the Clearfork. Average daily production from this well 
in 1997 was 11 BOE (barrel of oil equivalent). Neither of these wells 
produced in economic quantities and in April, 1998, the Company sold most of 
its interest in this project for $200,000 and retained a 6.875% working 
interest with the Company's share of the cost of drilling the next well being 
paid by the purchaser.

LAKOTA 3D SEISMIC EXPLORATION AND DEVELOPMENT PROJECT

  The Lakota project was acquired as a 3D seismic exploration project in 1995 in
the Northwest Shelf area of the Permian Basin in Terry County, Texas.  The
prospect was defined with a 14 square mile seismic survey and resulted in the
leasing of approximately 2,480 acres.  In 1997, one exploratory well was
completed in this project as a Wolfcamp discovery at a cost to the Company of 
$316,000.  The Company owns a 30% working interest in this project.  Average 
daily production from this well in 1997 was 14 BOE.  Due to lack of economic 
success, no additional wells are currently planned in this project.

RHODA WALKER (CHERRY CANYON) FIELD

  This field is located in Ward County, Texas, in which the Company has an
interest in 9 wells which are  operated by the Company with a combined average
production rate in 1997 of approximately 100 BOPD and 143 MCFD, subject to
normal declines.  During the fourth quarter of 1995, three Rhoda Walker Field
development wells were drilled at a cost to the Company of approximately
$880,000.  These wells increased oil and gas production from this field by 140%.
The Company owns a 100% working interest in this project.

                                    -5-
<PAGE>

ACKERLY (DEAN) FIELD

  This field is located in Dawson County, Texas, in which the Company has an
interest in 2 wells which are operated by the Company.  These wells combined
had a 1997 average production rate of approximately 41 BOPD and 20 MCFD gross
production before royalty burdens.  The Company owns a 100% working interest in
this project.

JAMESON (STRAWN) FIELD

  This field is located in Coke and Sterling Counties, Texas in which the
Company has an interest in 58 active wells which are operated by the Company
with a combined 1997 average production rate of approximately 120 BOPD and 1,500
MCFD.   At the time the Company acquired the Jameson properties in 1992, there
were 21 gross wells which were shut-in for various reasons by the former
operator.  The Company has returned 15 gross wells to production and has
converted nearly 40% of the wells from producing via conventional pumping unit
to a less expensive plunger lift method of artificial lift.

  In April and August 1996, the Company completed two field extension
development wells at an aggregate cost of approximately $700,000.  Average
aggregate gross production rates in 1997 from these wells was approxmiately 45
BOPD and 250 MCFD.  Effective June 1, 1996, the Company acquired various
additional royalty interests in this field for approximately $500,000.  The
Company owns a 100% working interest in this project and net revenue interests
on individual leases range from 90% to 92%.

COPE WATERFLOOD UNIT AND ADVANCED RESERVOIR MANAGEMENT PROJECT

  The Cope Unit is located in Sterling County, Texas.  This project encompasses
2,032 gross acres and at present has 21 gross active wells, 7 of which are
injectors.  At the time the Company acquired the Cope Unit in 1990, production
had declined to 100 BOPD.  Several shut-in wells were reactivated with total
unit production immediately improving to 137 BOPD.

  In early 1995, the Company began a joint project with the federal government's
Los Alamos National Laboratory to develop computerized 3D reservoir modeling and
simulation of the Company operated Cope Waterflood Unit.  Completed in 1997, the
simulation model is being utilized to improve reservoir management, potentially
enhance oil production by locating bypassed oil, determining new infill drilling
locations and designing optimum waterflood injection patterns for increased oil
recovery.

  Effective May 1, 1996, the Company acquired an additional l5.75% working
interest for approximately $79,000, and now owns approximately 77% of the
working interest in this property.  The Cope Unit produces from the Spraberry
formation.  In June 1996, the Company drilled a replacement well for one of the
producing wells in the unit which was producing mostly water.  The Cope Unit oil
production has been maintained at approximately 125 barrels of oil per day and
the unit's produced water has been reduced substantially.

                                    -6-
<PAGE>

OTHER PROPERTIES

  In August 1994, the Company acquired working interests in certain oil and gas
properties with 19 gross wells in Coke and Howard Counties, Texas, for
$1,950,000 which was adjusted for revenues and expenses through the closing
date.  These wells are operated by the Company and in 1997 had a combined
average production rate of approximately 62 BOPD and 215 MCFD, subject to normal
declines.  The Company owns a 100% working interest in these properties.

  In May 1995, the Company acquired a 50 percent working interest and operations
in three State tracts in Redfish Bay Field, Nueces County, Texas in return for a
commitment to expend $1,000,000 in capital expenditures over two years.   In
February 1997, the Company sold its interests in this field for $1,647,000.  The
Company realized a gain on this sale of approximately $349,000.

  In addition to the above described properties, the Company owns and operates
21 leases located within a 150 mile radius of Midland, Texas, containing 21
gross producing wells on 2,778 gross acres.  These wells are produced from the
Yates, Spraberry and Pennsylvanian formations at depths ranging from 1,800 feet
to 9,000 feet.  The production is heavily weighted to oil and some leases have
additional development opportunities.

  The following table sets forth information concerning the Company's leasehold
ownership interests as of December 31, 1997.

OIL AND GAS RESERVES

  The estimates of the Company's proved oil and gas reserves, which are 
located entirely within the United States, were prepared in accordance with 
the guidelines established by the SEC and Financial Accounting Standards 
Board.  The estimates of December 31, 1997 are based on evaluations prepared 
by Williamson Petroleum Consultants, Inc., Independent Petroleum Engineers.  
The estimates as of December 31, 1996 and 1995, are based on evaluations 
prepared by E. Ralph Green and Associates, Independent Petroleum Engineers. 
For information concerning costs incurred by the Company for oil and gas 
operations, net revenues from oil and gas production, estimated future net 
revenues attributable to the Company's oil reserves and present value of 
future net revenues on a 10% discount rate and changes therein, see Notes to 
the Company's consolidated financial statements. The Company emphasizes that 
reserve estimates are inherently imprecise and that estimates of new 
discoveries are more imprecise than those of producing oil and gas 
properties.  Accordingly, the estimates are subject to change as further 
information becomes available.

  As an operator of domestic oil and gas properties, the Company has filed 
Form EIA-23, "Annual Survey of Oil and Gas Reserves," with the Department of 
Energy as required by Public Law 93-275 and Public Law 95-91.  There are 
differences between the reserves reported on Form EIA-23 and the reserves 
reported herein. These differences are due to the fact that Form EIA-23 
requires an operator to report on total reserves attributable to wells which 
are operated by it, without regard to ownership.  The reserves reported 
herein are on a net interest basis.

  The estimated proved oil and gas reserves and present value of estimated 
future net revenues from proved oil and gas reserves for the Company as of 
December 31, 1997, 1996 and 1995, are summarized below:

The preceding tables should be read in connection with the following 
definitions:

PROVED RESERVES

     Estimated quantities of crude oil, natural gas and natural gas liquids
  which geological and engineering data demonstrate with reasonable certainty
  to be economically producible in future years from known reservoirs under
  existing economic and operating conditions, e.g., prices and costs as of
  the date the estimate was made, and assuming continuation of current
  regulatory practices using conventional production methods and equipment.

PROVED DEVELOPED RESERVES

     Proved oil and gas reserves which are expected to be recovered from
  existing wells with existing equipment and operating methods.  Developed
  reserves include both producing and non-producing reserves.  Producing
  reserves are those reserves expected to be recovered from existing
  completion intervals producing to a market as of the date of the
  appropriate reserve report.  Non-producing reserves are reserves that are
  currently shut-in awaiting a pipeline connection or in reservoirs behind
  the casing or at minor depths above or below the producing zone and are
  considered proved by production either from wells in the field, by
  successful drill-stem tests, or by core analyses from the particular zones.
  Non-producing reserves require only moderate expense for recovery.

PROVED UNDEVELOPED RESERVES

     Proved oil and gas reserves which are expected to be recoverable from
  additional wells yet to be drilled or from existing wells where a
  relatively major expenditure is required for completion.

     In estimating oil reserves for 1997, a price of $16.52 per barrel was
  used, which is the average actual price in effect for the Company's oil
  production on January 1, 1998.  In estimating gas reserves for 1997, a
  price of $2.36 per mcf, based on prices in effect at January 1, 1998, was
  used.

OTHER PROPERTY

  On July 11, 1995, the Company's office building located in Midland, Texas 
was sold to an unrelated third party and, in September, 1995, the Company 
moved its executive offices to leased space located at 16701 Greenspoint Park 
Drive, Suite 200, Houston, Texas  77060.  In November 1995, the Company 
purchased a 3,750 square foot building and 2.0 acres land located at 3419 
Hwy. 158, Midland, Texas, from a partnership of which Mr. Warley was a 50% 
owner, for use as a district office, warehouse and equipment yard.  During 
1997 the Company moved its executive offices to 616 F.M. 1960 West, Suite 
600, Houston, Texas 77090, which it currently occupies under a lease expiring 
in 2002.  The company also sold its district office and relocated in leased 
space in Midland, Texas.

ITEM 3.   LEGAL PROCEEDINGS

  The Company is a Defendant in a lawsuit filed on July 31, 1995, styled 
MANNA OIL & GAS, INC., DOBBS OIL & GAS, INC. V. MIDLAND RESOURCES, INC., 
MIRESCO, INC. MIDLAND RESOURCES OPERATING COMPANY, INC., Cause No. 40,677.  
The case involves certain Gulf Coast properties located in Copano Bay wherein 
the Company owns a 68% working interest and is the operator of the 
properties.  The Plaintiffs are (1) seeking a declarative judgment that the 
Company has failed to meet the standards and procedures set out in the 
Operating Agreement; (2) attempting to recover an unspecified sum; (3) are 
asking for an accounting for the years 1993-1995; and (4) attorney fees and 
costs.  The Company believes it has a defensible position with respect to all 
of the Plaintiffs' claims and intends to defend this case very aggressively.

  The Company filed a counterclaim against Manna Oil and Gas, Inc. ("Manna") 
in which the Company is seeking specific performance of an oral contract that 
the Company entered into with Manna, whereby the Company and Manna agreed 
that if either party acquired any additional property interest or contract 
rights of any kind in the properties that are the subject of the underlying 
lawsuit that said party would offer to convey to the other party their 
proportionate ownership in such newly acquired property interest or contract 
rights.  In the alternative, the Company claims that Manna breached such 
contract, and the Company is seeking monetary damages, resulting from said 
breach of contract, as well as attorney fees and court costs.

redemptions.

  On October 1, 1997, the Company issued 15,040 shares of unregistered common
stock to two directors in exchange for oil and gas working interests and a
limited partnership interest.  The Company relied upon Section 4(2) of  the
Securities Act of 1933 for an exemption from registering these shares  based
upon there being only two purchasers, the purchasers' access to Company
information and the business sophistication of the purchasers.

ITEM 6.   MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

  This discussion should be read in conjunction with the audited financial
statements of Midland Resources, Inc. and Subsidiaries.

PLAN OF OPERATIONS

  During 1996 and 1997 the Company's exploration efforts consumed most of its
available resources.  While the Company believes its exploratory efforts have
identified possible future drilling opportunities, its ability to actively
pursue these efforts as well as to actively exploit existing developed
properties is dependent upon securing additional capital.

  Beginning in early 1997 the Company determined that it should explore
strategic alternatives to raising capital though sales of equity.  To assist the
Company it engaged an investment banking firm.  During 1997 and continuing into
1998 the Company considered various alternative transactions, primarily
consisting of sale of all or substantially all of its assets, acquisitions of
another smaller company, merging with a company of equal size and merging with a
larger company.  The Company terminated its contract with its investment banking
firm in December 1997.

  On April 9, 1998, the Company announced it was pursuing a merger transaction
with Vista Resources, Inc., a privately held oil and gas exploration and
production company located in Midland, Texas.  If the transaction with Vista is
not consummated, the Company expects to restrict its operations, including
future development, to a level that its current operations can support, and
continue to seek a strategic transaction as well as consider the sale of equity.

  The Company's initial capitalization was through the acquisition of interests
of the seven public oil and gas income limited partnerships in exchange for
common stock and warrants of the Company.  There were 2,265,522 shares of common
stock issued and, for each share of common stock issued, two warrants were
issued entitling the holder to purchase one share of common stock at $2.50 and
one share at $4.00 during the period November 1990 to November 2002.  In
October, 1995, the Company called for redemption of its $2.50 warrants.  Holders
received a redemption payment of $0.05 per warrant for aggregate payments of
$63,373, which was charged to additional paid in capital.  997,009 of the $2.50
warrants were exercised, resulting in net proceeds of approximately $1,831,000.
As of December 31, 1997, 11,428 of the $4.00 warrants had been exercised.

  On December 31, 1993, the Company acquired all of the issued and outstanding
common stock of Midland Resources Operating Company, Inc. (MRO) through an
agreement of acquisition under which the Company issued 1,110,000 shares of
common stock to Deas H. Warley III and another former officer and director of
the Company.  The exchange was based on the relative fair values of the Company
and MRO, based on a determination by the Board of Directors of each respective
corporation.  The overall transaction was subject to a fairness opinion provided
by an investment banking firm.  The acquisition of MRO expanded the Company's
revenue base to include property operations.

  On December 20, 1996, the Company completed the acquisition of Summit
Petroleum Corporation ("Summit"), an affiliated entity engaged in oil and gas
acquisition, development and exploration activities which owned interests in
many of the same properties as the Company.  The Company's total cash investment
in acquiring Summit was approximately $2,011,000.  (See Note B of the Notes to
the Consolidated Financial Statements.)

CAPITAL RESOURCES AND LIQUIDITY

  Net cash provided by operations decreased from $1,893,641 in 1996 to
$1,393,461 in 1997, for a decrease of $500,180, reflecting decreased oil and
gas production and pricing, and increased production costs and interest expense,
partially offset by lower geological and geophysical costs.  Net cash used in
investing activities decreased from 1996 by $3,147,583, reflecting greater
proceeds from property sales in 1997 and the purchase of Summit in 1996.  Net
cash provided by financing activities decreased from 1996 by $2,715,257,
reflecting additional borrowings

                                     -12-

for property acquisition and development in 1997 and greater debt repayments
resulting primarily from the sale of the Redfish Bay properties in 1997.  In 
1997, acquisition costs for proved properties were $34,993, acquisition costs
for unproven properties were $836,863 and development costs were $1,716,294.  
Also, $1,536,130 was invested in an oil and gas limited partnership in 1997. 
In 1996, cash payments for oil and gas property acquisition costs totaled 
$761,476 for proved properties, $144,100 for unproved properties, and
$2,808,534 for development of properties.

  For 1997 the Company's working capital increased $95,170 over 1996.  The
principal components of this increase was the positive impact of approximately
$400,000 resulting from the sale of the Redfish Bay property in 1997 which was
offset by a reduction in current deferred tax assets of $341,000.

  Management believes current debt maturities can be funded from cash flow from
operations.  Management also believes that its credit facilities and its cash
flow from operations are adequate to meet its liquidity needs.  Any future
drilling will depend on the Company's ability to raise additional capital
through bank borrowings, private placements or merger transactions.

  At December 31, 1997, the Company has a net deferred tax asset of $1,048,193
which it believes can be realized based on estimates of future income from the
production of existing hydrocarbon reserves.  The net asset is primarily
composed of net operating loss carry-forwards which do not begin to expire until
2005.

  In October, 1996 the borrowing base under the Company's credit facility with
First Union National Bank (FUNB) was increased from $7,000,000 to $9,500,000 and
in March 1997 was reduced to $8,200,000 as a result of the sale of the Redfish
Bay properties.  The borrowing base was subsequently increased and, as of
December 1, 1997, was $9,125,000.  On December 17, 1997 this credit facility was
replaced with a revolving credit agreement with Compass Bank (Compass) which
provides for a credit facility of $30 million and an initial borrowing base of
$10,500,000.  Concurrent with the execution of this agreement, the Company's
outstanding debt to FUNB in the amount of $9,151,615 (including accrued interest
of $26,615), was paid by an advance under the Compass agreement.  Amounts
borrowed under the Compass agreement are collateralized by a first lien on
substantially all of the Company's oil and gas properties.  Interest under this
agreement is payable monthly at an annual rate which, at the Company's option,
is equal to either (a) the Compass prime lending rate (8.5% at December 31,
1997) or (b) the London Interbank Offered Rate, plus 2.5%.  In addition, a
commitment fee equal to 1/2% per annum on the unused portion of the borrowing
base is required.  The borrowing base is reduced at the rate of $120,000 per
month beginning February 1, 1998 and, is subject to redetermination on each
April 1st and October 1st.  This agreement also requires that the Company
maintain certain financial ratios and generally restricts the Company's ability
to incur debt, sell assets, materially change the nature of the Company's
business or its business structure or pay dividends.  At December 31, 1997 the
balance due under this agreement was $9,651,615 and in January, 1998 a principal
reduction in the amount of $551,615 was made from the collection of sales
proceeds from properties sold in December, 1997.  As of March 31, 1998, the
balance due under this facility was $9,200,000.

  In March 1, 1995, the Company entered into a one year gas swap agreement to
hedge against a portion of the price risk associated with gas price declines.
This swap agreement expired in February 1996, and the Company has not entered
into another contract.  Losses under this contract were $21,109 and $25,860 for
1995 and 1996, respectively.

  The prices of crude oil have fluctuated significantly in recent years as well
as in recent months.  As of December 31, 1997, the Company was receiving $16.52
per bbl as compared to $25.00 at January 1, 1997.  Fluctuations in price have a
significant impact on the Company's financial condition and liquidity.

  The following tables sets forth a summary of historical financial information
for the Company.  These tables should be read in conjunction with the
consolidated financial statements of Midland Resources, Inc. and Subsidiaries
(and the related notes).  It should be noted that there are no audited financial
statements included herein for the year 1994.  These tables are not covered by
the reports of independent certified public accountants.

RESULTS OF OPERATIONS - YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997

  During 1996, oil and gas sales increased from $5,147,033 in 1995 to
$6,958,491; an increase of $1,811,458 or 35%.  Oil production increased from
166,652 Bbls to 215,913 Bbls; an increase of 49,261 Bbls or 30%.  Gas production
decreased from 1,268,772 mcf to 1,002,482 mcf; a decrease of 266,290 mcf or 21%.
Sales and net production increases resulted from price increases as well as from
production from wells drilled and completed in the Jameson Field, and the
Wallace and Wilson properties in late 1995 and early 1996.  Average gas prices
increased from $1.79 per mcf in 1995 to $2.39 per mcf in 1996.  Oil prices
increased from $17.28 per bbl in 1995 to $21.15 per bbl in 1996.

   During 1997, oil and gas sales decreased from $6,958,491 to $6,396,249; a
decrease of $562,242, or 8%.  Oil production decreased from 215,913 Bbls to
192,580 Bbls; a decrease of 23,333 Bbls, or 11%.  Gas production decreased from
1,002,482 mcf to 988,109 mcf; a decrease of 14,373, or 1%.  Production declines
were due to the sale of the Redfish Bay properties, as well as normal production
declines on most wells, partially offset by production from new wells drilled in
1997.  Average oil prices declined from $21.15 in 1996 to $19.74 in 1997.
Average gas prices increased from $2.39 in 1996 to $2.63 in 1997.

  For 1997, the Company's share of income from an oil and gas limited
partnership was $72,275 which included oil and gas sales of $119,356 from
approximately 6,400 Bbls of oil produced.  There was no similar item in 1996.

   In 1996, production costs increased from $2,509,854 in 1995 to $2,981,837, an
increase of $471,983 or 19%.  This increase is attributable primarily to
additional producing wells as discussed above, as well as to production taxes
increasing as a result of increased oil and gas prices.  In 1997, production
costs increased from $2,981,837 in 1996 to $3,088,886, an increase of $107,049
or 4%.  This was due to major repairs and workovers conducted in 1997, partially
offset by decreased production costs resulting from the sale of Redfish Bay.

  During 1997 and 1996, exploration costs and abandonments were $943,294 and
$766,855, respectively, which were incurred in connection with the 3D 
exploration projects discussed above. These amounts include dry hole costs of
$796,852 in 1997 and $416,892 in 1996.

   In 1996, depreciation depletion and amortization (DD&A) was $1,306,287 as
compared to $1,033,905 in 1995, for an increase of $272,382 or 26%.  This was
due primarily to an increase in property investments resulting from the
completion of additional wells and to the acquisition of Summit. In 1997, DD&A
was $1,964,658, an increase of $658,371 from 1996, or 50%.  This was due to
lower oil and gas reserves at December 31, 1997, which was due to less than
desired economic success on some wells drilled in 1997 and to lower oil prices.

   In 1996, general and administrative (G&A) expenses increased from $1,049,904
in 1995 to $1,295,298, an increase of $245,394 or 23%.  This increase was
attributable primarily to the write off in 1996 of approximately $115,000 of
acquisition costs associated with an attempt to acquire another public
independent oil and gas company, as well as to increased labor costs associated
with the company's relocation from Midland, Texas, to Houston, Texas.  In 1997,
G&A expenses were $1,451,404 for an increase of $156,106, or 12%, over 1996.
This was due primarily to increased legal and consulting fees, and to non-cash
stock based compensation expense of $217,484.  These costs were partially offset
by lower costs in other areas due to cost reduction measures.

  Impairment losses were $1,020,670 in 1995, $114,904 in 1996 and $1,277,342 in
1997.  Impairments are recognized when estimated future net cash flows on
individual properties are less than their net capitalized cost.

  In 1997, there were gains of $462,571 primarily from the sales of oil and gas
properties, including $349,000 from the sale of the Redfish Bay property.

  In 1996, interest expenses increased to $722,447, an increase of $110,860, or
18% from 1995.  This increase is attributable to additional borrowings to
consummate the Summit acquisition and for property acquisitions and development
projects in 1996.  In 1997, interest increased to $970,430, an increase of
$247,983, or 34%, due primarily to additional borrowings to fund the Company's
drilling program in 1997 and to pay $84,800 to close an interest rate swap
contract.

  In 1995, the net loss was $737,031 primarily resulting from an impairment loss
of $1,020,670, the loss on sale of properties and equipment of $102,984 and the
incurrence of exploration costs totaling $198,453:  In 1996, net income was
$22,122, due primarily to higher prices for oil and gas production and lower
impairment losses, partially offset by increases in production costs, G&A
expenses and other factors discussed above.  In 1997, the net loss was
$1,883,382, due primarily to property impairments, DD&A, lower oil and gas
production, exploratory dry holes and other factors discussed above.

ITEM 7.   FINANCIAL STATEMENTS

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders
Midland Resources, Inc.

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

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

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

NOTE A.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

  ORGANIZATION AND BASIS OF PRESENTATION

      Midland Resources, Inc. ("Company"), was organized in 1990 with the issue
  of common stock and warrants in exchange for oil and gas partnership
  interests.  The Company and its wholly owned subsidiaries are headquartered
  in Houston, Texas.  The Company is involved in the acquisition, exploration,
  development and production of oil and gas and owns producing properties and
  undeveloped acreage and royalty interests in Texas, Illinois and Colorado.
  The majority of its activities are centered in the Permian Basin of West
  Texas.  Midland Resources Operating Company Inc. ("MRO"), a wholly owned
  subsidiary, is in the business of oil and gas property operations.  Summit
  Petroleum Corporation ("Summit") is a wholly owned subsidiary engaged in oil
  and gas acquisition, exploration, development and production.  (See Note B.)

  PRINCIPLES OF CONSOLIDATION

      The accompanying consolidated balance sheets include the accounts of the
  Company and its wholly owned subsidiaries.  All significant inter-company
  balance sheet accounts have been eliminated in consolidation.  All
  significant inter-company transactions have been eliminated from the
  consolidated statements of operations and cash flows for the years ended
  December 31, 1997, 1996 and 1995.

  RECLASSIFICATIONS

       Certain reclassifications have been made to conform to the 1997 
  presentation.

  OIL AND GAS OPERATIONS

      The Company follows the "successful efforts" method of accounting for oil
  and gas properties.  All costs associated with the acquisition and
  development of proved oil and gas properties are capitalized.

      Costs associated with exploratory drilling are capitalized pending
  evaluation of drilling results.  Costs of exploratory wells which do not find
  proved results are expensed.  Geological, geophysical and delay rental costs
  are expensed as incurred.

      Depreciation, depletion and amortization of oil and gas properties is
  computed on a property-by-property basis using the units-of-production method
  based upon estimated oil and gas reserve quantities.

      Oil and gas revenues are recognized under the sales method at the point of
  delivery to the purchaser.  No significant over or under produced positions
  between the Company and its working interest partners exist.

      During the fourth quarter of 1995, the Company adopted the provisions of
  the Financial Accounting Standards Board's Statement No. 121, "Accounting for
  the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
  Of" ("FAS 121").  FAS 121 requires impairment losses to be recognized on long-
  lived assets used in operations when indicators of impairment are present and
  the undiscounted cash flows estimated to be generated by these assets are
  less than the assets' carrying amount.  It also requires assets held for sale
  to be valued at the lesser of their original carrying amount or fair value.
  Concurrent with the adoption and decision to market certain oil and gas
  properties, the Company recognized a write-down of $1,020,670.  In 1996 and
  1997, the Company recognized losses of $114,904 and $1,277,342, respectively.

                                      -23-

  OTHER PROPERTY AND EQUIPMENT

      All other property and equipment is depreciated on the straight-line 
  method over lives ranging from 5 to 6 years.

  INTANGIBLE ASSETS

      Goodwill is amortized on the straight-line method over 30 years.  Property
  operating contracts are amortized on the straight-line method over the lives
  of the respective oil and gas properties which range from 3 to 19 years.

  ACCOUNTING FOR STOCK OPTIONS

      The Company accounts for employee stock option grants in accordance with
  APB Opinion No. 25, "Accounting for Stock Issued to Employees," and related
  interpretations, whereby compensation costs are recognized only in situations
  where stock compensatory plans award intrinsic value to recipients at the
  date of grant.

  USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
  accepted accounting principles requires management to make estimates and
  assumptions that affect the amounts reported in the financial statements and
  accompanying notes.  Actual results could differ from those estimates.  The
  most significant estimates affecting the Company's financial statements are
  the determination of hydrocarbon reserves, the estimated useful lives of
  depreciable and amortizable assets, and the fair value of assets held for
  sale.

  INCOME TAXES

      The Company recognizes deferred tax assets and liabilities for the future
  tax consequences of differences between the financial statement carrying
  amounts of assets and liabilities and their respective tax bases.  Deferred
  tax assets and liabilities are measured using enacted tax rates applicable to
  the years in which those temporary differences are expected to be recovered
  or settled.  The effect on deferred tax assets and liabilities of a change in
  tax rates is recognized in income in the period that includes the enactment
  date.

  EARNINGS (LOSS) PER COMMON SHARE

      Effective December 31, 1997, the Company retroactively adopted the
  provisions of Statement of Financial Accounting Standards No. 128 for all
  periods presented.  Basic earnings per share is calculated by dividing net
  income by the weighted average number of common shares outstanding during
  each year.  Dilutive earnings per share is calculated by dividing net income
  by the weighted average number of common and dilutive potential common
  shares.  Stock options and warrants may be potential dilutive common shares
  and are therefore considered in the earnings per share calculation, if
  dilutive.  The number of dilutive potential common shares is determined using
  the treasury stock method.  Shares used to compute basic and diluted earnings
  (loss) per share were 4,433,113, 4,395,414 and 3,381,592 in 1997, 1996 and
  1995, respecively.

  EMPLOYEE BENEFITS

      Prior to 1995, the Company maintained a 401(k) Plan which covered
  substantially all full-time employees.  In 1995, the Board of Directors
  authorized the restatement of the plan as the Midland Resources

  Operating Company, Inc. 401(k) Employee's Stock Ownership Plan and Trust and
  the contribution of 5,000 shares of treasury stock to the restated plan.  An
  additional 7,300 shares of treasury stock were contributed in 1996.  As of 
  December 31, 1995 and 1996, all shares had been allocated to participants in 
  the plan.  The Company matches employee contributions up to 3 percent of 
  gross salary.  The expense related to the Company's contributions and plan 
  administration was $26,517, $50,092, and $25,985 in 1997, 1996 and 1995, 
  respectively.

  FINANCIAL INSTRUMENTS

      The carrying amount of cash approximates fair value.  Interest rates
  associated with substantially all the Company's long-term debt are linked to
  current market rates.  As a result, management believes that the carrying
  amount approximates the fair value of the Company's credit facilities.

NOTE B.  PURCHASE OF SUBSIDIARY CORPORATION

    On September 18, 1996, the Company, through MRI Acquisition Corp. (a 
wholly owned subsidiary), acquired 81.5% of the issued and outstanding common 
stock and all outstanding stock options of Summit Petroleum Corporation (See 
Note F.) for cash of $1,081,188 and cancellation of a note receivable from an 
officer/stockholder of both the Company and Summit of $479,648.  In December 
1996, the Summit stockholders approved a plan of merger whereby Summit became 
a wholly owned subsidiary of the Company.  Pursuant to this plan, 
stockholders possessing the remaining 18.5% interest (443,633 shares), upon 
tendering their shares, receive $0.70 per share.  During 1997, payments of 
$89,139 were made for 127,341 shares tendered.  The Company's liability for 
the purchase of these remaining shares, which is being funded through 
long-term borrowings under the Company's revolving credit agreement (See Note 
C.), is included as a non-current liability in the accompanying balance 
sheet.  The purchase price ($0.70 per share and $0.6375 per option) was based 
on the fair value of Summit's net assets as determined by the Board of 
Directors of each respective corporation.  The transaction was subject to a 
fairness opinion provided by a recognized investment banking firm relative to 
these values.  In addition to the purchase price, the Company incurred 
$139,254 in costs directly related to this acquisition, resulting in a total 
investment through December 31, 1997, of $2,010,633.  This acquisition is 
accounted for under the purchase method of accounting, which provides that 
the results of operations are combined from the date of acquisition 
(September 18, 1996).  In December 1996, MRI Acquisition Corp. was dissolved 
and Summit became a wholly-owned subsidiary of the Company.

     In December, 1997 the Company entered into a revolving credit agreement 
with Compass Bank (Compass) which provides for a credit facility of $30 
million and an initial borrowing base of $10,500,000.  Concurrent with the 
execution of this agreement, the Company's outstanding debt to First Union 
National Bank (FUNB) in the amount of $9,151,615 was paid by an advance under 
the Compass agreement. Amounts borrowed under the Compass agreement are 
collateralized by a first lien on substantially all of the Company's oil and 
gas properties.  Interest under this agreement is payable monthly at an 
annual rate which, at the Company's option, is equal to either (a) the 
Compass prime lending rate (8.5% at December 31, 1997) or (b) the London 
Interbank Offered Rate, plus 2.5%.  In addition, a commitment fee equal to 
1/2% per annum on the unused portion of the borrowing base is required.  The 
borrowing base is reduced at the rate of $120,000 per month beginning 
February 1, 1998 and is subject to redetermination on each April 1st and 
October 1st.  This agreement also requires that the Company maintain certain 
financial ratios and generally restricts the Company's ability to incur debt, 
sell assets, materially change the nature of the Company's business structure 
or pay dividends.

NOTE D.  ISSUANCE OF COMMON STOCK AND WARRANTS

  In November 1990, the Company issued 2,264,522 shares of common stock, as 
discussed in Note A, based on an exchange value of $2.00 per share.  For each 
share of common stock issued, two warrants were issued entitling the holder 
to purchase one share of common stock at $2.50 and one share at $4.00 during 
the period from November 1990 to November 2002.  On October 6, 1995, the 90 
day common stock market price requirement (as defined in the Warrant 
Agreement) was met and the Company called its $2.50 warrants.  Holders of 
record on December 22, 1995 received a redemption payment of $0.05 per 
warrant for aggregate payments of $63,373, which was charged to additional 
paid in capital.  997,009 of the $2.50 warrants were exercised.  As of 
December 31, 1997, 11,428 of the $4.00 warrants had been exercised.

  The warrants are subject to certain antidilution provisions contained in 
the warrant agreement, which could cause adjustments to the exercise price 
and the number of shares issuable.

  The Company has two employee stock option plans which reserve an aggregate 
of 700,000 shares of common stock for issuance to officers and other key 
employees. As of December 31, 1997 options to acquire 260,000 shares at 
prices ranging from $2.375 to $4.00 were outstanding under these plans with 
scheduled expiration dates of 1998 through 2002.  As of December 31, 1997, 
376,500 shares were available for future grant.

  Under the Midland Resources, Inc. 1995 Directors' Stock Option Plan, 20,000 
stock options with a five year term were granted to directors in 1995.  As of 
December 31, 1995, all 20,000 options were outstanding under this plan.  In 
1996, an additional 30,000 stock options were granted to directors.  Each 
option entitles the holder to purchase one share of common stock for the fair 
market value of common stock on the date of the grant of the option.  As of 
December 31, 1997, 50,000 options were outstanding under this plan at 
exercise prices ranging from $2.75 to $3.75 and 50,000 options were available 
for future grant. Options outstanding at December 31, 1997, if not exercised, 
are scheduled to expire in 1999 through 2001.

  In May 1997, the Shareholders ratified the Midland Resources, Inc. 1997 
Board of Directors Stock Incentive Plan under which 1,000,000 options were 
issued to non-employee directors, 175,000 options were issued to the advisory 
director and 60,000 were issued to the corporate secretary, all to acquire 
shares at $3.00 per share.  These options are vested as certain stipulated 
trading prices for the Company's common stock are achieved and, 
exercisability is further restricted by time delay provisions which limited 
the number of vested shares that may be exercised each year beginning in 
March 1998.  As of December 31, 1997, 247,000 of these options were vested.  
Upon a change of control, as defined, all of these options became 
exercisable. These options, if not exercised, expire in March, 2002.  Also in 
February, 1997, the Company issued a five year warrant to purchase 50,000 
shares to a consultant for future services.  These options and warrants are 
expected to give rise to the recognition of

                                      -28-

NOTE D. (CONTINUED)

compensation expenses of up to $616,250 through year 2000.  In 1997, 
stock-based compensation expense of $217,484 was recognized in connection 
with these issuances.

  In June 1995, the Company issued 150,000 warrants to purchase common stock 
at $4.00 per share for a term of seven years to FUNB.  In exchange the 
Company's credit facility loan agreement was amended to reduce the interest 
rate by 0.75% and allow 25% of its borrowing base to be used for working 
capital purposes. The fair value of the warrants at the date of grant was 
recorded as debt discount and additional paid in capital.  None of these 
warrants have been exercised as of December 31, 1997.

  Warrants to purchase an additional 70,000 shares of common stock were 
issued in 1994 through 1996 in exchange for investment banking and other 
services, with exercise prices ranging from $2.50 to $2.875.

  Effective January 1, 1996, the Financial Accounting Standards Board (FASB) 
issued Statement of Financial Accounting Standards No. 123, which provides 
for an alternative method to valuation of the compensation element of stock 
based compensation plans.  The Company applies APB 25 and related 
Interpretations in accounting for employee stock-based compensation.  Had 
compensation costs been determined based on the fair value at the grant dates 
for awards consistent with the method of FASB Statement 123, the Company's 
net income (loss) and related per share amounts would have been reduced to 
the pro forma amounts indicated below:

NOTE E.  MAJOR CUSTOMERS

  The Company and its subsidiaries operate exclusively within the United States
and their revenues and operating income are derived predominately from the oil
and gas industry.  Oil and gas production is sold to various purchasers and the
receivables are generally uncollateralized.  The Company has not experienced
significant credit losses on its oil and gas accounts and management is of the
opinion that significant credit risk does not exist. Management is of the
opinion that the loss of any one purchaser would not have an adverse effect on
the ability of the Company to sell its oil and gas production.

  In 1997, three purchasers accounted for 18%, 15% and 12%, respectively, of
total oil and gas revenues.   In 1996, three purchasers accounted for 18%, 12%
and 15%, respectively, of total oil and gas revenues.  In 1995, four purchasers
accounted for 18%, 17%, 11% and 11%, respectively, of total oil and gas
revenues.

NOTE F.  RELATED PARTIES

  Until December 1993, MRO was owned 80% by the Company's then President and 
Chairman of the Board of Directors, Mr. Deas H. Warley III and 20% by a former
Vice President and Board Member, Sal J. Pagano.  Mr. Warley currently owns 
approximately 16% of the Company's outstanding common stock and 5% of the 
related $4.00 warrants.

  Effective November 1, 1995, the Company purchased a building and land in
Midland County, Texas, for $78,996 from Mr. Warley and another individual for
use as a district office.  Mr. Warley and the other individual each financed 50%
of the purchase price less the down payment of $10,496.  The two $34,250 ten
year notes bore interest at 7.5% and were payable in equal monthly installments
of $407 each.  The cost to the Company was based on an independent written
appraisal and certain improvements completed before the property was purchased.
This property was sold in 1997 at a gain of $46,500.

  In December 1995, Mr. Warley borrowed $582,805 from the Company under an
eighteen month term note bearing 7.5% interest, secured by 287,947 shares of
the Company's common stock.  Mr. Warley used these funds to exercise his 233,122
warrants to buy common stock at $2.50 per share.  The balance of the note
payable to Mr. Warley discussed above  was netted against this note receivable
and he made a cash payment of $95,000 leaving a balance of $453,641 at December
31, 1995.  This amount was reflected in the financial statements as a reduction
of stockholders' equity at December 31, 1995.  This note was paid in full in
September 1996 by offsetting the balance of $479,648 against the payment to Mr.
Warley for his stock and options in Summit Petroleum Corporation (See Note B.).

NOTE F. (CONTINUED)

  During 1995, Summit participated with the Company in the acquisition of
certain oil and gas leases and seismic options in the Sunburst Project, Terry
County, Texas, and the Latigo and Lakota Projects, Hockley County, Texas in
exchange for a commitment from the Company and Summit to expend certain monies
in connection with acquiring an interest in certain oil and gas leases, seismic
options, conducting 3D geological surveys, interpretation of 3D seismic data and
the drilling of two or more test wells.  Summit acquired its five percent
interest working interest in proportion to its share of the commitment.

  Effective September 1, 1995, Summit participated with the Company in the
acquisition of additional working interests in certain Redfish Bay properties in
Nueces County, Texas.  Summit acquired its four percent working interest on the
same basis as the Company.

  The amounts due from a related party at December 31, 1996, represents
reimbursements due for certain acquisition and exploration costs from a limited
partnership, formed in January, 1997, for which the Company served as general
partner.  Amounts due from a related party at December 31, 1997 represents
amounts due from this partnership for property operations and drilling costs.
The limited partnership group was initially comprised of 19 individuals of which
18 were also stockholders of the Company.  In addition, two of these individuals
are directors of the Company.  During 1997, the Company's interest was assigned
to the Company in the form of oil and gas property interests and, effective
December 31, 1997 the Company withdrew from the partnership.

  During 1997, the Company acquired working interests from two directors and a
partnership interest from one of these directors for cash consideration of
$144,879 and 15,040 shares of common stock valued at $52,625.

NOTE G.  COMMITMENTS AND CONTINGENCIES

  The Company is involved in litigation arising in the ordinary course of
business.  Management believes the ultimate resolution of these matters will not
have a material effect on the consolidated financial statements.

  The Company leases its executive office space and a field office under
noncancellable operating leases expiring in 2002. Rental expense was $34,560 in
1995, $92,088 in 1996, and $93,988 in 1997.  Future minimum rental commitments,
as of December 31, 1997, for these leases are as follows:

  For income tax purposes, the Company has net losses of approximately
$2,963,000 available for carryforward which, if not utilized, will begin to
expire in 2005.  Management has determined that, based on future expectations,
it is more likely than not that the Company's future taxable income will be
sufficient to fully utilize these losses prior to their expiration.  In
addition, the Company has losses of approximately $610,000 which, if not
utilized, will begin to expire in 1998.  Management has determined that, based
on future expectations, it is more likely than not, that approximately $431,000
of this amount will not be utilized and, accordingly, has established a
valuation allowance.

NOTE J.  HEDGING ACTIVITIES

     Effective March 1, 1995, the Company entered into a one year gas swap 
agreement to hedge against a portion of the price risk associated with gas 
price declines.  This agreement covers approximately 50% of the Company's 
total estimated gas production.  The Company's price under this agreement is 
a minimum of $1.50 per mcf with a 40% participation in prices over $1.50.  
This swap agreement expired in February, 1996, and the Company has not 
entered into another contract.  Losses under this contract were $21,109 and 
$25,860 for 1995 and 1996, respectively.  Gains or losses relating to the 
swap agreement are measured, settled and recognized at the end of each month 
as part of oil and gas sales.

NOTE M.  OIL AND GAS RESERVES (UNAUDITED)

     The estimates of the Company's proved oil and gas reserves, which are 
located entirely within the United States, were prepared in accordance with 
the guidelines established by the Securities and Exchange Commission and 
Financial Accounting Standards Board which require that reserve estimates be 
prepared under existing economic and operating conditions, with no provision 
for price and cost escalators, except by contractual agreement.  These 
estimates as of December 31, 1997 are based on evaluations prepared by 
Williamson Petroleum Consultants, Inc., Independent Petroleum Engineers.  The 
estimates as of December 31, 1996 and 1995 are based on evaluations prepared 
by E. Ralph Green and Associates, Independent Petroleum Engineers.

     Management emphasizes that reserve estimates are inherently imprecise 
and are expected to change as new information is available and as economic 
conditions in the industry change.

                               CERTIFICATE OF SECRETARY



     I, Marilyn D. Wade, the duly elected and qualified Secretary of Midland 
Resources, Inc. (the "Company"), do hereby certify that the following 
Resolution of the Board of Directors of the Company was duly and validly 
adopted at a properly convened meeting thereof on the 17th day of September, 
1997, adopted in accordance with the Bylaws of the Company and remains in 
full force and effect on the date hereof without modification or amendment:

     RESOLVED, that this corporation Amend SECTION 3.2. SPECIAL MEETINGS.,
     so the text reads as follows:

     "Except as otherwise provided by law or by the Articles of Incorporation,
     special meetings of the shareholders may be called by the Chairman of the
     Board of Directors, the President, any two of the directors, or by the
     Company pursuant to written request by the holders of not less than 
     one-tenth of all the shares having voting power at such meeting, and 
     shall be held at the principal office of the Corporation, if called by 
     holder(s) of not less than one-tenth of all the shares having voting 
     power at such meeting, or if called as otherwise provided herein, at such
     other place, and in either case, at such time, as may be stated in the 
     notice calling such meeting. Business transacted at any special meeting 
     of shareholders shall be limited to the purpose stated in the notice of 
     such meeting given in accordance with the terms of Section 3.3."

 .    FURTHER RESOLVED, Amend SECTION 3.4. CLOSING OF TRANSFER BOOKS AND FIXING
     RECORD DATE., by changing the heading thereof to read 

     "SECTION 3.4. RECORD DATE FOR SHAREHOLDER NOTICE." and adding the 
     following at the end thereof:

     "The record date for determining those shareholders entitled to vote at a
     special meeting of shareholders called by holder(s) of not less than 
     one-tenth of all the shares having voting power at such meeting, shall be
     a date established by the Board of Directors within twenty business days
     following written receipt of the request to call such meeting by such
     holder(s) of not less than one-tenth of all the shares having voting power
     at such meeting delivered to the Secretary of the Corporation.  In the
     absence of the Board of Directors establishing such a record date within
     twenty business, such record date shall be deemed as the first business 
     day following the expiration of the twenty business days within which 
     the Board had to establish such a record date."

     FURTHER RESOLVED, Amend SECTION 3.7. VOTING AT MEETINGS., by adding
     the following to the end thereof:

     "The Board of Directors may establish procedures to be followed in counting
     votes on any matter, whether by proxy or in person, not inconsistent with
     the Articles of Incorporation or the laws of the State of Texas. Such
     procedures may address whether or not, and to what extent and how, all 
     shares a shareholder is entitled to vote shall be voted, when any such
     shareholder submits a ballot or proxy that does not contain voting
     directions thereon as to any one or more matters, or attempts to vote less
     than all shares owned by such shareholder.  To the extent to Board of
     Directors adopts any such procedures, it shall give notice thereof to those
     shareholders entitled to vote at any meeting of shareholders at which such
     procedures have been adopted."

<PAGE>

 .    FURTHER RESOLVED, Amend SECTION 4.1 NUMBER, QUALIFICATION AND TERM., by
     deleting the second and third sentences and replacing them with the
     following:

     "The Board of Directors shall consist of not less than three nor more than
     eleven members.  The exact number of directors shall be five until changed,
     within the preceding limits, by resolution amending such exact number, duly
     adopted by at least seventy-five percent (75%) of the entire Board, or the
     affirmative vote of the shareholders holding a majority of the shares
     entitled to vote on the election of directors; and provided that no
     decrease shall effect a shortening of the term of any incumbent director."

     Signed this 27th day of January, 1998.

                            ARTICLE II.  THE LOAN

          2.01 THE REVOLVING LINE.  Upon the terms and conditions (including, 
without limitation, the right of Bank to terminate the Revolving Commitment 
hereunder upon an Event of Default or an Unmatured Event of Default) and 
relying on the representations and warranties contained in this Agreement, 
Bank agrees, for a period from and after the date hereof through the last 
Business Day prior to the Maturity Date, to make advances for the account of 
Borrower from time to time following receipt of a Request for Advance; 
provided, however, that the aggregate principal amount of all Loans plus the

          Through the last Business Day prior to the Maturity Date, Borrower 
may use this revolving credit by borrowing, prepaying and reborrowing, all in 
accordance with the terms and conditions of this Agreement.  The borrowings 
made by Borrower pursuant to the Revolving Commitment shall be made at the 
principal office of Bank and shall be evidenced by the Note.  The entire 
principal amount of the Note is due on the Maturity Date.  Each Borrower, 
other than MRI, hereby appoints MRI as its agent and attorney-in-fact for 
purposes of submitting all Requests for Advance hereunder and for purposes of 
giving and receiving all notices and other communications permitted or 
required by this Agreement and either receiving or directing the disposition 
of all advances and letter 

                                      10
<PAGE>

of credit, respectively, made or issued by Bank pursuant to this Agreement.  
Each Borrower, other than MRI, hereby ratifies, adopts and confirms all acts 
heretofore or hereafter taken by MRI on behalf of such Borrower in connection 
with this Agreement and/or any of the other Loan Documents executed in 
connection herewith.

          2.02 ADVANCES AND PAYMENTS OF PRINCIPAL UNDER THE NOTE.  Each time 
an advance is made against or payment is made on the Note, Bank is hereby 
irrevocably authorized by Borrower to make appropriate entries of such in its 
records in accordance with the usual and customary practices of accounting 
for advances and payments on notes; provided, however, the failure of Bank to 
do so shall not relieve Borrower of its correct liability hereunder or under 
the Note.

          The aggregate unpaid amount of advances reflected by the notations 
by Bank on its records or the ledger sheets affixed to the Note shall be 
deemed rebuttably presumptive evidence of the principal amount owing on the 
Note.  The liability for payment of principal and interest evidenced by the 
Note shall be limited to principal amounts actually advanced to Borrower and 
outstanding under this Agreement and interest on such amounts calculated in 
accordance with this Agreement.  Interest provided for in the Note and herein 
shall be calculated on unpaid sums actually advanced and outstanding under 
the Note pursuant to the terms of this Agreement and only for the period from 
the date or dates of such advances until repayment.  

          2.03 PREPAYMENT AND CONVERSION.  Upon the Required Number of days 
notice to the Bank, the Borrower may: (a) without the payment of penalty or 
premium, prepay the principal of the Loans, or (b) voluntarily convert the 
applicable Interest Rate of any Loan prior to the termination of the 
applicable Interest Period in whole or in part, from time to time; any 
partial payment or conversion to be made in the sum of not less than $500,000 
or any $100,000 increment in addition thereto; PROVIDED that with respect to 
any such prepayment or conversion of any Loan upon which interest is being 
calculated at the LIBOR Rate the Borrower shall reimburse the Bank on demand 
for any costs, including administrative costs, incurred by the Bank as a 
result of such prepayment or conversion and any loss incurred or to be 
incurred by the Bank in the redeployment of the funds released by any such 
prepayment.  Such loss shall be the difference, as reasonably determined by 
Bank, between (i) Bank's gross return hereunder with respect to that portion 
of the Loans which is prepaid, based on the applicable Interest Rate for such 
portion of the Loans and (ii) any lesser amount realized by Bank in deploying 
the funds received in repayment, or otherwise realized from that portion of 
the Loans so prepaid, during the period from the date of the prepayment until 
the end of the Interest Period for that portion of the Loans prepaid; 
provided that Bank shall use its best efforts to redeploy such funds in a 
commercially reasonable manner.

          2.04 INTEREST RATE AND PAYMENTS OF INTEREST.

          (A)  Interest on Index Rate Loans shall be calculated on the basis of
          a year of 365 or 366 days, as appropriate.  Interest on LIBOR Loans
          shall be calculated on the basis of a 360-day year, counting the
          actual number of days elapsed.  Interest on the outstanding principal
          balance of the Loans shall accrue for each day at either the Floating
          Rate for such day or the LIBOR Rate for the Interest Period which
          includes such day, all as elected and specified (including
          specification as to length of Interest Period, as permitted by the
          definition of that term, with respect to any election of the LIBOR
          Rate) by the Borrower in accordance with Section 2.04(B); provided
          that:

               (i)  In the absence of an election by the Borrower of the LIBOR
               Rate, or, having made such election but upon the Required Number
               of days prior to the end of the then current Interest Period the
               Borrower fails or is not entitled under the terms of this
               Agreement to elect to continue such Interest Rate and specify the
               applicable Interest Period therefor, then upon the expiration of
               such then current Interest Period, interest on the Loans shall
               accrue for each day at the Floating Rate for such day, until the
               Borrower, pursuant to Section 2.04(B), elects a different
               Interest Rate and specifies the Interest Period for the Loans.

               (ii) Interest accruing on any LIBOR Loan during any Interest
               Period shall be payable on the last Business Day of such then
               current Interest Period; PROVIDED, that all accrued interest on
               any LIBOR Loan converted or prepaid pursuant to Section 2.03
               shall be paid immediately upon such prepayment or conversion.

          (B)  By at least the Required Number of days prior to the advance of
          any Loan hereunder, Borrower shall select the initial Interest Rate to
          be charged on such Loan, and from time to time thereafter the Borrower
          may elect, on at least the Required Number of days' irrevocable prior
          written (or telephoned, promptly confirmed by written) notice to the
          Bank, to change the Interest Rate on any Loan to any other Interest
          Rate (including, when applicable, the selection of the Interest
          Period); PROVIDED that; (i) the Borrower shall not select an Interest
          Period that extends beyond the Termination Date; (ii) except as
          otherwise provided in Section 2.03 no such change from the LIBOR Rate
          to another Interest Rate shall become effective on a day other than
          the day, which must be a Business Day, next following the last day of
          the 

                                      12
<PAGE>

          Interest Period last effective for such LIBOR Loan; (iii) any
          elections made by the Borrower pursuant to this Section 2.04(B) shall
          be in the amount of $100,000, plus any additional increment of
          $100,000; (iv) notwithstanding anything herein to the contrary, the
          Borrower may not make any election under this Section 2.04(B) that
          would result in Loans outstanding at more than three (3) different
          LIBOR Rates without the written agreement of the Bank to do so; and
          (v) the first day of each Interest Period as to a LIBOR Loan shall be
          a Business Day.

          (C)  Interest on Index Rate Loans shall be paid monthly in arrears on
          the first day of each calendar month commencing with any month during
          which interest begins to accrue at the Floating Rate, as elected by
          Borrower pursuant to Section 2.04(B), and on the date the principal of
          such Loans shall be due (at stated maturity, on acceleration, or
          otherwise).

          (D)  Interest on past-due principal shall accrue at the greater of the
          applicable Floating Rate plus three percent (3.00%) or LIBOR plus five
          percent (5.00%) until such principal is paid in full, and shall be
          payable upon demand by the Bank.

          (E)  The Bank shall notify the Borrower of the current Index Rate and
          of the current LIBOR Rate from time to time upon request by the
          Borrower.

          (F)  It is the intention of the parties hereto to conform strictly to
          applicable usury laws as in effect from time to time.  Accordingly, if
          any transactions contemplated hereby would be usurious under
          applicable Law (including the laws of the United States of America, or
          of any other jurisdiction whose laws may be mandatorily applicable),
          then, in that event, notwithstanding anything to the contrary in this
          Agreement, or any other agreement entered into in connection with this
          Agreement, it is agreed the aggregate of all consideration that
          constitutes interest under applicable law that is contracted for,
          charged, or received under this Agreement, or under any of the other
          aforesaid agreements or otherwise in connection with this Agreement
          shall under no circumstances exceed the Maximum Rate, and any excess
          shall be credited to the Borrower by Bank (or, if such consideration
          shall have been paid in full, such excess refunded to the Borrower by
          Bank).  All sums paid, or agreed to be paid, to the Bank for use,
          forbearance, and detention of the indebtedness of the Borrower by the
          Bank shall, to the extent permitted by applicable laws, be amortized,
          pro rated, allocated, and spread throughout the full term of such
          indebtedness 

                                      13
<PAGE>
          until such indebtedness is paid in full so that the actual rate of 
          interest is uniform, but does not exceed the Maximum Rate, 
          throughout the full term thereof.  If at any time the applicable 
          Interest Rate, which shall be deemed for purposes of this Section 
          2.04(F), only, to include any other fees, charges, or other forms 
          of consideration which constitute interest under applicable law 
          that is contracted for, charged, or received under this Agreement 
          or any other agreement entered into in connection with this 
          Agreement, exceeds the Maximum Rate, the rate of interest to accrue 
          pursuant to this Agreement shall be limited, notwithstanding 
          anything to the contrary in this Agreement, to the Maximum Rate, 
          but any subsequent reductions in the Interest Rate otherwise 
          provided for herein shall not reduce the interest to accrue 
          pursuant to this Agreement below the Maximum Rate until the total 
          amount of interest accrued pursuant to this Agreement equals the 
          amount of interest that would have accrued if a varying rate per 
          annum equal to the otherwise applicable Interest Rate had at all 
          times been in effect.  If the total amount of interest paid or 
          accrued pursuant to this Agreement under the foregoing provisions 
          is less than the total amount of interest that would have accrued 
          if a varying rate per annum equal to the otherwise applicable 
          Interest Rate had at all times been in effect, then the Borrower 
          agrees to pay upon final maturity of the Loans an amount equal to 
          the difference between (a) the lesser of (i) the amount of interest 
          that would have accrued if the Maximum Rate had at all times been 
          in effect or (ii) the amount of interest that would have accrued if 
          a varying rate per annum equal to the otherwise applicable Interest 
          Rate had at all times been in effect, and (b) the amount of 
          interest accrued in accordance with the other provisions of this 
          Agreement.

          2.05 INCREASED COST OF LOANS.

          (A)  Notwithstanding any other provisions herein, if as a result of
          any regulatory change

               (i)  the basis of taxation of payments to Bank of the principal
               of, or interest on, any LIBOR Loan or any other amounts due under
               this Agreement in respect of any such LIBOR Loan (except for
               taxes imposed on the overall net income or receipts of Bank, and
               franchise or other taxes imposed generally on Bank), by the
               jurisdiction (or any political subdivision therein) in which Bank
               has its principal office (if such other taxes do not specifically
               affect the cost to Bank of making the Loans) is changed;

                                      14
<PAGE>

               (ii)  any reserve, special deposit, or similar requirement
               (including without limitation any reserve requirement under
               regulations of the Board of Governors of the Federal Reserve
               System) against assets of, deposits with, or for the account of,
               or credit extended by Bank, is imposed, increased, modified, or
               deemed applicable; or 

               (iii)  any other condition affecting this Agreement or any LIBOR
               Loan is imposed on Bank or (in the case of LIBOR Loans) the
               London interbank market;

          and the result of any of the foregoing is to increase the actual
          direct cost to Bank of making or maintaining any such LIBOR Loan or to
          reduce the amount of any sum received by Bank hereunder in respect
          thereof (and such increase or reduction shall not have been
          compensated by a corresponding increase in the interest rate
          applicable to the respective Loans), by an amount deemed by Bank to be
          material (such increases in cost and reductions in amounts receivable
          being herein called "Increased Costs"), then the Borrower shall pay to
          Bank, within thirty (30) days after its demand, such additional amount
          or amounts as will compensate Bank for those Increased Costs.  The
          Bank will not demand to be compensated by Borrower for such Increased
          Costs unless the Bank generally makes such demands to its other LIBOR
          Loan customers who are similarly situated.  A certificate of Bank
          setting forth the basis for the determination of such amount necessary
          to compensate the Bank as aforesaid, accompanied by documentation
          showing reasonable support for such increased costs or reduced sums
          received by Bank, shall be delivered to the Borrower and shall be
          conclusive, save for manifest error, as to such determination and such
          amount.

          (B)  Notwithstanding the foregoing provisions of this Section 2.05, in
          the event that by reason of any regulatory change the Bank either
          (i) incurs Increased Costs based on, or measured by, the excess above
          a specified level of the amount of a category of deposits or other
          liabilities of Bank that includes deposits by reference to which the
          interest rate on LIBOR Loans is determined as provided in this
          Agreement or a category of extensions of credit or other assets of
          such Bank that includes LIBOR Loans or (ii) becomes subject to
          restrictions on the amount of such a category of liabilities or assets
          that it may hold, then, if Bank so elects by notice to the Borrower,
          the obligation of Bank to make or convert Loans of any other type into
          LIBOR Loans hereunder shall be suspended until the earlier of 

                                      15
<PAGE>

          the date such regulatory change ceases to be in effect or the date 
          the Borrower and Bank agree upon an alternative method of 
          determining the interest rate payable by the Borrower on LIBOR 
          Loans, and all LIBOR Loans of Bank then outstanding shall be 
          converted into an Index Rate Loan (if not otherwise prohibited 
          under the terms of this Agreement) at the Borrower's option.

          (C)  Bank agrees that upon the occurrence of any regulatory change
          giving rise to the operation of the first paragraph of this Section
          2.05, it will, if requested by the Borrower and to the extent
          permitted by law or by the relevant government authority, for a period
          of thirty (30) days endeavor in good faith to avoid or minimize the
          increase in cost or reduction in amount receivable resulting from such
          regulatory change; PROVIDED, however, that such change can be made in
          such a manner that Bank, in its sole determination, suffers no
          economic, legal, regulatory, or other disadvantage.  Any expense
          incurred by Bank in so doing shall be paid by the Borrower on delivery
          to the Borrower of a certificate as to the amount of such expense,
          which certificate shall be conclusive in the absence of manifest
          error.  Nothing in this paragraph shall affect or postpone the
          obligations of the Borrower set forth in any other paragraph of this
          Section 2.05.

          2.06 SUBSTITUTE RATE.  Anything herein to the contrary 
notwithstanding, if within two (2) Business Days prior to the first day of 
any Interest Period for a LIBOR Loan the Bank is not, for any reason 
whatsoever, quoted rates for the offering of Dollars for deposit with it in 
the London interbank market for a period and amount relevant to the 
computation of the rate of interest on LIBOR Loans for such Interest Period, 
the Bank shall give the Borrower prompt notice thereof and on what would 
otherwise be the first day of such Interest Period such Loans shall be made 
as Index Rate Loans (if not otherwise prohibited under the terms of this 
Agreement), at the Borrower's option in accordance with the election 
procedures set forth in Section 2.04(B); PROVIDED, however, that prior to the 
effective date of such election, interest shall be calculated at the Floating 
Rate.  

          2.07 CHANGE OF LAW.  Notwithstanding any other provision herein, in 
the event that any change in any applicable law, rule or regulation or in the 
interpretation or administration thereof shall make it unlawful for the Bank 
to (i) honor any commitment it may have hereunder to make any LIBOR Loan, 
then such commitment shall terminate, or (ii) maintain any LIBOR Loan, then 
all LIBOR Loans of the Bank then outstanding shall be repaid and converted to 
Index Rate Loans (if not otherwise prohibited under the terms of this 
Agreement) at the Borrower's option in accordance with the election 
procedures set forth in Section 2.04(B); PROVIDED, however, that prior to the 
effective date of such election, interest shall be

                                      16
<PAGE>

calculated at the Floating Rate.  Any remaining commitment of Bank hereunder 
to make LIBOR Loans (but not other Loans) shall terminate forthwith.  Upon 
the occurrence of any such change, the Bank shall promptly notify the 
Borrower thereof, and shall furnish to the Borrower in writing evidence 
thereof certified by the Bank.

          Any repayment or conversion of any LIBOR Loan which is required 
under this Section 2.07 or under 2.05(B) shall be effected by payment 
thereof, together with accrued interest thereon, on demand, and concurrently 
there shall occur the borrowing of the corresponding Index Rate Loan as 
provided herein.

          If any repayment to Bank of any LIBOR Loan (including conversions 
thereof) is made under this Section 2.07 on a day other than a day otherwise 
scheduled for a payment of principal of or interest on such Loan, the 
Borrower shall pay to Bank upon its request such amount or amounts as will 
compensate it for the amount by which the rate of interest on such Loan 
immediately prior to such repayment exceeds the stated rate of interest on 
relending or reinvesting the funds received in connection with such 
prepayment, in each case for the period from the date of such prepayment to 
the Business Day next succeeding the last day of such then current Interest 
Period, all as determined by Bank in its good faith discretion.

          2.08  ADVANCES TO SATISFY OBLIGATIONS OF BORROWER.  Bank may, but 
shall not be obligated to, make advances hereunder and apply same to the 
satisfaction of any condition, warranty, representation or covenant of 
Borrower contained in this Agreement, and the funds so advanced and applied 
shall be part of the Loan proceeds advanced under this Agreement and 
evidenced by the Note.

          2.09  MANDATORY PREPAYMENT OF THE NOTES.  In the event that Bank or 
Borrower determine that a Loan Excess exists, Borrower shall immediately, but 
in no event later than thirty (30) days following the earlier of either: (a) 
Borrower becoming aware that a Loan Excess exists, or (b) notice from Bank of 
any such determination, (i) prepay the principal of the Note in an aggregate 
amount at least equal to such Loan Excess or (ii) add to the Borrowing Base 
Properties additional Oil and Gas Properties of Borrower sufficient in value, 
as determined by Bank in its sole discretion pursuant to Section 2.10, to 
increase the Borrowing Base to equal the unpaid principal amount of the Note 
plus all accrued, unpaid interest.

          2.10  BORROWING BASE DETERMINATION.

                a.  BORROWING BASE PROPERTIES.  The initial Borrowing Base 
attributable to the Borrowing Base Properties is hereby established at 
$10,500,000.00 effective as of the date hereof.  Subject to the other 
provisions of this Agreement, the Borrowing Base shall be automatically 
reduced on the first day of each month, commencing on February 1, 1998, by 
the Monthly

                                      17
<PAGE>

Borrowing Base Reduction, which is initially established at $120,000.00.  On 
or before April 1, 1998, Borrower shall furnish to Bank a petroleum 
engineering report relative to the Proved Reserves that are attributable to 
the Borrowing Base Properties effective as of January 1, 1998, as well as 
such other information as Bank may request regarding volumes of production 
produced and sold, contracts, pricing, gross revenues, expenses, and other 
information and engineering and geological data as may relate to the 
Borrowing Base Properties (collectively the "Borrowing Base Property Data").  
Upon receipt of such Borrowing Base Property Data, Bank shall, in the normal 
course of business, redetermine the Borrowing Base and the Monthly Borrowing 
Base Reduction attributed to the Borrowing Base Properties, which 
redetermination shall become effective upon written notification from Bank to 
Borrower, and which, subject to the other provisions of this Agreement, shall 
be the basis on which the Borrowing Base shall thereafter be calculated until 
the effective date of the next redetermination of the Borrowing Base and the 
Monthly Borrowing Base Reduction as set forth in this Section.  Thereafter, 
on or before each succeeding October 1 and April 1 until the Maturity Date, 
Borrower shall furnish to Bank a report, in form and substance satisfactory 
to Bank, which report shall set forth, as of each preceding July 1 or January 
1, as applicable, such Borrowing Base Property Data as Bank may request 
attributable to the Borrowing Base Properties.  Each report to be provided on 
or before each April 1 shall be a complete report relating to the Borrowing 
Base Properties, which may be prepared by Borrower, but which shall be 
reviewed and concurred with in writing by an independent petroleum engineer 
or firm of engineers satisfactory to Bank. Each report to be provided on or 
before each October 1 shall simply update the previous complete report, and 
may be prepared by Borrower's own engineers and shall be certified by the 
President of MRI.  Upon receipt of each such report, Bank shall, in the 
normal course of business, make a determination of the Borrowing Base and the 
Monthly Borrowing Base Reduction which shall become effective upon written 
notification from Bank to Borrower, and which, subject to the other 
provisions of this Agreement, shall be the basis on which the Borrowing Base 
attributable to the Borrowing Base Properties shall thereafter be calculated 
until the effective date of the next redetermination of the Borrowing Base 
and the Monthly Borrowing Base Reduction as set forth in this Section.  

          Beginning with the delivery of the Borrowing Base Property Data due 
by April 1, 1998, and continuing as and when Borrower is required to provide 
to Bank each semi-annual report, as required by the provisions of this 
Section, Borrower shall contemporaneously pay an engineering fee of $7,500.00 
to Bank for Bank's analysis of such report and redetermination of the 
Borrowing Base and the Monthly Borrowing Base Reduction.  At any time 
engineering reviews are requested by Borrower in connection with a Borrowing 
Base redetermination, other than the semi-annual reviews required by Bank, an 
additional fee of $7,500.00 shall be paid to

                                       18
<PAGE>

Bank for Bank's analysis of such report and redetermination of the Borrowing 
Base.

                b.  EQUITY CUSHION.  The Borrowing Base shall represent 
Bank's determination, in accordance with its customary lending practices in 
effect from time to time, of the maximum loan amount that may be supported by 
the Borrowing Base Properties.  Borrower and Bank acknowledge that (i) due to 
the uncertainties of the oil and gas extraction process, the Borrowing Base 
Properties are not subject to evaluation with a high degree of accuracy and 
are subject to potential rapid deterioration in value, and (ii) for this 
reason and the difficulties and expenses involved in liquidating and 
collecting against the Borrowing Base Properties, Bank's determination of the 
maximum loan amount with respect to the Borrowing Base Properties contains an 
equity cushion, which equity cushion is acknowledged by Borrower as essential 
for the adequate protection of Bank.

                c.  UNSCHEDULED BORROWING BASE REDETERMINATIONS.  In addition 
to scheduled redeterminations of the Borrowing Base, the Bank may redetermine 
the Borrowing Base and the Monthly Borrowing Base Reduction at any time, and 
from time to time, which redetermination shall become effective upon written 
notification from Bank to Borrower and which, subject to the other provisions 
of this Agreement, shall be the basis on which the Borrowing Base shall 
thereafter be calculated until the effective date of the next redetermination 
of the Borrowing Base and the Monthly Borrowing Base Reduction, as set forth 
in this Section.

          2.11  ASSIGNMENT OF PRODUCTION.  Certain of the Security 
Instruments covering the Borrowing Base Properties contain an assignment unto 
and in favor of Bank of all oil, gas and other minerals produced and to be 
produced from or attributable to the Oil and Gas Properties that constitute 
part of the Borrowing Base Properties, together with all of the revenues and 
proceeds attributable to such production, and such Security Instruments 
further provide that all such revenues and proceeds which may be so collected 
by Bank pursuant to the assignment shall be applied to the payment of the 
Note and the satisfaction of all other Indebtedness to be secured by such 
Security Instruments.  Such Security Instruments further provide that the 
Bank grants to Borrower a license to receive and collect the revenues and 
proceeds attributable to such production unless and until an Event of Default 
shall occur, and upon the occurrence of an Event of Default, the Bank, acting 
in its sole discretion, shall have the right to terminate Borrower's license 
to collect such revenues and proceeds.  Borrower hereby appoints Bank as its 
agent and attorney-in-fact for all purposes deemed by Bank to be necessary or 
desirable in connection with such assignment of production, including, but 
not limited to, completing the letter transfer orders delivered to Bank 
pursuant to Sections 3.14 and/or 3.17 hereof, which power is coupled with an 
interest and is not revocable.

                                       19

          2.12  COMMITMENT FEE.  As consideration for the commitment of Bank 
to make Loans to Borrower through the Maturity Date pursuant to this 
Agreement, Borrower agrees to pay to Bank within five (5) Business Days of 
receipt of Bank's statement as to quarterly periods ending March 31, June 30, 
September 30 and December 31 of each year (except the first period shall be 
for a period of time from the Closing to December 31, 1997) during the period 
commencing on the date of this Agreement to and including the Maturity Date 
and at the Maturity Date, a fee equal to 1/2 of 1% per annum (computed on the 
basis of 365 or 366 days, as the case may be) multiplied by an amount equal 
to the daily average excess, if any, of the Borrowing Base over the sum of: 
(x) the aggregate principal amount outstanding on the Note, plus (y) the 
aggregate face amount of all outstanding Letters of Credit, throughout the 
period from the date of this Agreement or previous calculation date provided 
above, whichever is later, to the relevant calculation date or the Maturity 
Date, as the case may be.

          2.13  FACILITY FEE.  As consideration for the commitment of Bank to 
make Loans to Borrower pursuant to this Agreement, Borrower shall pay to Bank 
at Closing a fee ("FACILITY FEE") equal to one-half of one percent (.5%) of 
the initial Revolving Commitment, and if and when the Revolving Commitment is 
subsequently increased, then Borrower shall pay to Bank an additional 
Facility Fee equal to one half of one percent (.5%) of the amount by which 
such increased Revolving Commitment exceeds the highest Revolving Commitment 
amount previously in effect.  

          2.14  ADDITION OF BORROWING BASE PROPERTIES.  Borrower may, from 
time to time upon thirty (30) days prior written notice to Bank, propose to

such proposal to add Oil and Gas Properties of Borrower to the Borrowing Base 
Properties shall be accompanied by an engineering report applicable to such 
Oil and Gas Properties that conforms to the requirements of Section 2.10, 
evidence sufficient to establish that Borrower has Marketable Title to such 
Oil and Gas Properties, and such other data as Bank may reasonably request.  
Any such additions shall become effective at such time as: (a) Bank has made 
its determination in the ordinary course of business of the amount by which 
the Borrowing Base would be increased as the result of such addition and (b) 
the conditions set forth in Article III hereof, to the extent they are 
applicable to such additional Borrowing Base Properties of Borrower, have 
been satisfied.

          2.15  LETTERS OF CREDIT.  Subject to the terms and conditions of

Advance three (3) Business Days prior to the requested date of issuance in 
such amount as the Borrower may request in an aggregate amount of up to (i) 
One Million Dollars ($1,000,000.00), but (ii) not to exceed at any time the 
unborrowed portion of the Revolving Commitment.  The amount of

                                       20

any such Letters of Credit issued under the Revolving Commitment shall be 
deemed to be a Loan and to reduce the amount available under the Revolving 
Commitment and shall be governed by the terms of this Agreement.  The Bank 
may require in connection with the issuance of any Letter of Credit that 
Borrower execute the Bank's then-current form of application for a Letter of 
Credit, but if there is any conflict between the terms of any such 
application and the terms of this Agreement, the terms of this Agreement 
shall control.  No Letter of Credit shall have an expiration date that is 
later than one year from the date of its issuance, or, if sooner, beyond the 
Maturity Date.

beneficiary of a Letter of Credit, all amounts so drawn shall be due and 
payable by the Borrower immediately upon receipt of Bank's statement therefor.

the Bank of Letters of Credit for the account of the Borrower, the Borrower 
agrees to pay to the Bank a fee of one and one-half percent (1.5%), per 
annum, of the amount of each such Letter of Credit (subject to a $500.00 
minimum fee per year on each Letter of Credit), the first such per annum fee 
for each Letter of Credit to be payable in advance of the issuance of such 
Letter of Credit, with successive per annum fees to be paid in advance of the 
anniversary date of the issuance of such Letter of Credit if it is to remain 
in effect beyond such anniversary date.

                 ARTICLE IV.  REPRESENTATIONS AND WARRANTIES

          To induce Bank to enter into this Agreement and to make the Loan 
hereunder, each Borrower represents and warrants to Bank (which 
representations and warranties will survive the delivery of the Note) that:

          4.01  EXISTENCE AND GOOD STANDING.  Borrower is a corporation, duly 
organized, legally existing and in good standing under the laws of its 
jurisdiction of incorporation and is duly qualified and in good standing as a 
foreign corporation in all jurisdictions wherein the property owned or the 
business transacted by it makes such qualification necessary, other than 
those jurisdictions wherein the failure to so qualify does not have a 
material adverse effect on Borrower.

          4.02  DUE AUTHORIZATION.  The execution and delivery by Borrower of 
this Agreement and the borrowings hereunder; the execution and delivery by 
Borrower of the Note and the Security Instruments; and the repayment by 
Borrower of Indebtedness evidenced by the Note and interest and fees provided 
in the Note and this Agreement are (a) within the corporate power of 
Borrower; (b) have been duly authorized by all necessary corporate action; 
and (c) do not and will not (i) require the consent of any regulatory 
authority, governmental body, or any other Person, (ii) violate any provision 
of law, the certificate of incorporation, the articles of incorporation, or 
the bylaws of Borrower, (iii) cause a default to occur under the terms and 
provisions of any indenture, instrument or other agreement to which Borrower 
is a party or by which its property may be presently bound or encumbered, or 
(iv) result in or require the creation or imposition of any mortgage, lien, 
pledge, security interest, charge or other encumbrance in, upon or of any of 
the properties or assets of Borrower under any such indenture, instrument or 
other agreement, other than under any of the Security Instruments.

          4.03  VALID AND BINDING OBLIGATIONS.  This Agreement, the Note, and 
the Security Instruments are the legal, valid and binding obligations of and 
enforceable against Borrower in accordance with their respective terms 
(subject to any applicable bankruptcy, insolvency or other laws of general 
application affecting creditors' rights and judicial decisions interpreting 
any of the foregoing).  In addition, the First Union Loan Agreement, the 
First Union Loan Documents, and the Indebtedness evidenced thereby, are the 
legal, valid and binding obligations of each Borrower that is party thereto 
in accordance with their respective terms (subject to any applicable 
bankruptcy, insolvency or other laws of general application affecting 
creditors' rights and judicial decisions interpreting any of the foregoing), 
and Borrower is not in default in any material respect of any of its 
obligations under the First

                                       24
<PAGE>

perform, respectively, any of the Indebtedness of other obligations evidenced 
thereby.

          4.04  TITLE TO BORROWING BASE PROPERTIES.  Borrower has Marketable 
Title to all of its Borrowing Base Properties.

          4.05  OIL AND GAS LEASES.  The Leases which constitute any part of 
the Borrowing Base Properties are in full force and effect, are valid, 
subsisting leases covering the entire estates to which they pertain and all 
rentals, royalties and other amounts due and payable in accordance with the 
terms of the Leases, overriding royalties, net profits or other production 
burdens have been duly paid or provided for; the obligations to be performed 
under the Leases have been duly performed; and Borrower is not aware of any 
default by any third party under any of the Leases with respect to such third 
party's obligations.

          4.06  INTEREST IN THE BORROWING BASE PROPERTIES.  With respect to 
each of the Borrowing Base Properties, the ownership of Borrower in such 
property will, with respect to the wells, units and/or tracts of land 
described in Schedule 1.01(a) hereto in connection with such property, (i) 
entitle Borrower to receive (subject to the terms and provisions of this 
Agreement) a decimal share of the oil and gas produced from, or allocated to, 
such wells, units and/or tracts equal to not less than the decimal share set 
forth in Schedule 1.01(a) in connection with such wells, units and/or tracts, 
and (ii) cause Borrower to be obligated to bear a decimal share of the cost 
of exploration, development and operation of such wells, units and/or tracts 
of land not greater than the decimal share set forth in Schedule 1.01(a) in 
connection with such wells, units and/or tracts, unless any increase in 
Borrower's share of costs is accompanied by a pro-rata increase in Borrower's 
share of revenue.  Except as set forth in the instrument and agreements, if 
any, more particularly described in Schedule 1.01(a), all such shares of 
production which Borrower is entitled to receive, and shares of expenses 
which Borrower is obligated to bear, are not subject to change, except for 
changes attributable to future elections by Borrower not to participate in 
operations proposed pursuant to customary forms of applicable joint operating 
agreements, and except for changes attributable to changes in participating 
areas under any federal units wherein participating areas may be formed, 
enlarged or contracted in accordance with the rules and regulations of the 
applicable governmental authority.

          4.07  OIL AND GAS CONTRACTS.  Borrower is not obligated, by virtue 
of any prepayment under any contract providing for the sale by Borrower of 
hydrocarbons which contains a "take-or-pay" clause or under any similar 
prepayment agreement or arrangement, including, without limitation, "gas 
balancing agreements", to deliver a material amount of hydrocarbons produced 
from the Borrowing Base Properties at some future time without then or 
thereafter receiving full payment therefor (I.E., in the case of

                                       25
<PAGE>

oil, not in excess of sixty (60) days, and in the case of gas, not in excess 
of ninety (90) days).  The Borrowing Base Properties are not subject to any 
contractual, or other arrangement for the sale of crude oil which cannot be 
cancelled on ninety (90) days' (or less) notice, unless the price provided 
for therein is equal to or greater than the prevailing market price in the 
vicinity.  The Borrowing Base Properties are not subject to any gas sales 
contract that contains any material terms which are not customary in the 
industry within the region in which the Borrowing Base Properties affected 
thereby are located.  The Borrowing Base Properties are not subject to any 
regulatory refund obligation and no facts exist which might cause the same to 
be imposed.

          4.08  PRODUCING WELLS.  All producing wells located on the 
Borrowing Base Properties have been, during all times that such were under 
the direction or control of Borrower and, to the knowledge of Borrower, at 
all other times, drilled, operated and produced in conformity with all 
applicable laws, rules, regulations and orders of all regulatory authorities 
having jurisdiction, are subject to no penalties on account of past 
production, and are bottomed under and are producing from, and the well bores 
are wholly within, the Borrowing Base Properties or on Oil and Gas Properties 
which have been pooled, unitized or communitized with the Borrowing Base 
Properties.

          4.09  PURCHASERS OF PRODUCTION.  The persons who are purchasing 
Borrower's interests in oil and gas produced from the Borrowing Base 
Properties as of the calendar month during which the Loans are made hereunder 
are identified on Schedule 4.09 attached hereto.

          4.10  SCOPE AND ACCURACY OF FINANCIAL STATEMENTS.  All Financial 
Statements submitted and to be submitted to Bank hereunder are and will be 
complete and correct in all material respects; are and will be prepared in 
accordance with GAAP and practices consistently applied; and do and will 
fairly reflect the financial condition and the results of the operations of 
Borrower in all material respects as of the dates and for the period stated 
therein (subject only to normal year-end audit adjustments with respect to 
such unaudited interim statements); and no material adverse change has since 
occurred in the condition, financial or otherwise, of Borrower or its 
Subsidiaries (taken as a whole).

          4.11  LIABILITIES, LITIGATION AND RESTRICTIONS.  Except as 
disclosed in the Financial Statements, Borrower has no liabilities, direct or 
contingent, which may materially and adversely affect its business or assets. 
Except as described on the Financial Statements or on Schedule 4.11, there is 
no litigation or other action of any nature pending before any court, 
governmental instrumentality, regulatory authority or arbitral body or, to 
the knowledge of Borrower, threatened against or affecting Borrower, or any 
of its Subsidiaries, which might reasonably be expected to result in any 
material, adverse change in the business

                                       26
<PAGE>

or assets of Borrower or its Subsidiaries (taken as a whole).  No unusual or 
unduly burdensome restriction, restraint or hazard exists by contract, law, 
governmental regulation or otherwise relative to the business or material 
properties of Borrower other than such as relate generally to Persons engaged 
in the business activities conducted by Borrower.

          4.12  MARGIN STOCK.  None of the proceeds of the Loans will be used 
for the purpose of buying or carrying margin stock.

          4.13  AUTHORIZATIONS AND CONSENTS.  No authorization, consent, 
approval, exemption, franchise, permit or license of, or filing with, any 
governmental or public authority or any third party is required to authorize, 
or is otherwise required in connection with the valid execution and delivery 
by Borrower of this Agreement, the Note, and the Security Instruments to 
which it is a party or any instrument contemplated hereby, the repayment by 
Borrower of advances against the Note and interest and fees provided in the 
Note and this Agreement, or the performance by Borrower of its obligations 
under any of the foregoing.

          4.14  COMPLIANCE WITH LAWS, RULES, REGULATIONS AND ORDERS.  To the 
best of the knowledge and belief of Borrower, neither the business nor any of 
the activities of Borrower, as presently conducted, violates any law or any 
rule, regulation or directive of any applicable judicial, administrative or 
other governmental instrumentality (including, but not by way of limitation, 
any law or any rule, regulation or directive of any judicial, administrative 
or other governmental instrumentality relating to zoning, to any 
Environmental Law, to the stabilization of wages or prices or to the 
development, production, transportation or purchase or sale of oil, gas or 
other hydrocarbons) the result of which violation would have a material 
adverse effect on Borrower or its Subsidiaries (taken as a whole), and 
Borrower possesses all licenses, approvals, registrations, permits and other 
authorizations necessary to enable it to carry on its business in all 
material respects as now conducted, and all such licenses, approvals, 
registrations, permits and other authorizations are in full force and effect; 
and Borrower has no reason to believe that it will be unable to obtain the 
renewal of any such licenses, approvals, registrations, permits and other 
authorizations.

          4.15  PROPER FILING OF TAX RETURNS AND PAYMENT OF TAXES DUE.  
Borrower has duly and properly filed all United States Income Tax returns and 
all other tax returns which are required to be filed, and has paid all taxes 
due pursuant to said returns or pursuant to any assessment received, except 
such taxes, if any, as are being contested in good faith and as to which 
adequate provisions and disclosures have been made; and the respective 
charges and reserves on the books of Borrower with respect to any taxes or 
other governmental charges are adequate.

                                       27
<PAGE>

          4.16  ERISA.  Borrower is in compliance in all material respects 
with all applicable provisions of ERISA.  Neither a Reportable Event nor a 
Prohibited Transaction has occurred and is continuing with respect to any 
plan; no notice of intent to terminate a plan has been filed, nor has any 
plan been terminated; no circumstances exist which constitute grounds under 
Section 4042 of ERISA entitling the PBGC to institute proceedings to 
terminate, or appoint a trustee to administrate a plan, nor has the PBGC 
instituted any such proceedings; neither Borrower nor any ERISA Affiliate has 
completely or partially withdrawn under Sections 4201 or 4204 of ERISA from a 
Multi-employer plan; Borrower and each ERISA Affiliate have met their minimum 
funding requirements under ERISA with respect to all of their plans and the 
present value of all vested benefits under each plan exceeds the fair market 
value of all plan assets allocable to such benefits, as determined on the 
most recent valuation date of the plan and in accordance with the provisions 
of ERISA and the regulations thereunder for calculating the potential 
liability of Borrower or any ERISA Affiliate to the PBGC or the plan under 
Title IV of ERISA; and neither Borrower nor any ERISA Affiliate has incurred 
any liability to the PBGC under ERISA.

          4.17  INVESTMENT COMPANY ACT COMPLIANCE.  Borrower is not, nor is 
it directly or indirectly controlled by or acting on behalf of any person or 
entity which is, an investment company or an "affiliated person" of an 
investment company within the meaning of the Investment Borrower Act of 1940.

          4.18  PUBLIC UTILITY HOLDING COMPANY ACT COMPLIANCE.  Borrower is 
not a "holding company", or an "affiliate" of a "holding company" or of a 
"subsidiary company" of a "holding company", within the meaning of the Public 
Utility Holding Company Act of 1935, as amended.

          4.19  ENVIRONMENTAL LAWS.  To the best of the knowledge and belief 
of Borrower:

     system or waste treatment, storage or disposal system servicing any 
     property of Borrower; and

          (d)   no complaint, order, directive, claim, citation, notice of 
     environmental report, notice of investigation or other notice by any

provided, however, that the representations and warranties set forth in 
subparagraphs (c) and (d) above shall apply only to events and conditions 
which either resulted in (i) a continuing lien or encumbrance on the property 
of Borrower or (ii) otherwise materially affect Borrower's use or operation 
of its property or Borrower's ability to repay the Indebtedness evidenced by 
the Note.

                                   SCHEDULE 1.01(A)

                              BORROWING BASE PROPERTIES

This Schedule 1.01(a) sets forth the description of the initial Borrowing 
Base Properties covered by the Agreement to which this Schedule 1.01(a) is 
attached. All of the terms defined in the Agreement are used in this Schedule 
1.01(a) with the same meanings given therein.

The Borrowing Base Properties include:

     (a)  All of Borrower's right, title and interest in and to the oil, gas 
and mineral leases described herein and/or lands described in and subject to 
such oil, gas and mineral leases (regardless, as to such leases and/or lands, 
of any surface acreage and/or depth limitations set forth in any description 
of any of such oil, gas and mineral leases), and all of Borrower's right, 
title and interest in and to any of the oil, gas and minerals in, on or under 
the lands, if any, described on this Schedule 1.01(a), including, without 
limitation, all contractual rights, fee interests, leasehold interests, 
overriding royalty interests, non-participating royalty interests, mineral 
interests, production payments, net profits interests, or any other interest 
measured by or payable out of production of oil, gas or other minerals from 
the oil, gas and mineral leases and/or lands described herein; and

     (b)  All of the foregoing interests of Borrower as such interests may be 
enlarged by the discharge of any payments out of production or by the removal 
of any charges or encumbrances together with Borrower's interests in, to and 
under or derived from all renewals and extensions of any oil, gas and mineral 
leases described herein, it being specifically intended hereby that any new 
oil and gas lease (i) in which an interest is acquired by Borrower after the 
termination or expiration of any oil and gas lease, the interests of Borrower 
in, to and under or derived from which are subject to the lien and security 
interest hereof, and (ii) that covers all or any part of the property 
described in and covered by such terminated or expired leases, shall, to the 
extent, and only to the extent such new oil and gas lease may cover such 
property, be considered a renewal or extension of such terminated or expired 
lease; and

     (c)  All right, title and interest of Borrower in, to and under or 
derived from any operating, farmout, and bidding agreements, assignments and 
subleases, whether or not described in this Schedule 1.01(a), to the extent, 
and only to the extent, that such agreements, assignments and subleases (i) 
cover or include any of Borrower's present right, title and interest in and 
to the leases and/or lands described in this Schedule 1.01(a), or (ii) cover 
or include any other undivided interests now or hereafter held by Borrower 
in, to and under the described leases and/or lands, including, without 
limitation, any future operating, farmout and bidding agreements, 
assignments, subleases and pooling, unitization and communitization 
agreements and the units created 

                               Page 1.01(a)-1
<PAGE>

thereby (including, without limitation all units formed under orders, 
regulations, rules or other official acts of any governmental body or agency 
having jurisdiction) to the extent and only to the extent that such 
agreements, assignments, subleases, or units cover or include the described 
leases and/or lands; and

     (d)  All right, title, and interest of Borrower in, to and under or 
derived from all presently existing and future advance payment agreements, 
oil, casinghead gas and gas sales, exchange, and processing contracts and 
agreements including, without limitation, those contracts and agreements that 
are described on this Schedule 1.01(a) to the extent, and only to the extent, 
those contracts and agreements cover or include the described leases and/or 
lands herein; and

     (e)  All right, title and interest of Borrower in, to and under or 
derived from all existing and future permits, licenses, easements and similar 
rights and privileges that relate to or are appurtenant to any of the 
described leases and/or lands.

          Notwithstanding the intention of this Agreement to cover all of the 
right, title and interest of Borrower in and to the described leases and/or 
lands, Borrower hereby specifically warrants and represents that the 
interests covered by this Schedule 1.01(a) are not greater than the working 
interest nor less than the net revenue interest, overriding royalty interest, 
net profit interest, production payment interest or other interest payable 
out of or measured by production set forth in connection with each oil and 
gas well described in this Schedule 1.01(a).  In the event Borrower owns any 
other or greater interest, such additional interest shall also be covered by 
and included in this Agreement.  The designation "Working Interest" or "W.I." 
means an interest owned in an oil, gas, and mineral lease that determines the 
cost bearing percentage of the owner of such interest.  The designation "Net 
Revenue Interest" or "NRI" means net revenue interest, or that portion of the 
production attributable to the owner of a working interest after deduction 
for all royalty burdens, overriding royalty burdens, or other burdens on 
production, except severance, production, windfall profits and other similar 
taxes.  The designation "Overriding Royalty Interest" or "ORRI" means an 
interest in production which is free of any obligation for the expense of 
exploration, development and production, bearing only its pro rata share of 
severance, production, windfall profits and other similar taxes.

$30,000,000.00                   Houston, Texas               December 17, 1997

     On the dates hereinafter prescribed, for value received, MIDLAND 
RESOURCES, INC., a Texas corporation, MIDLAND RESOURCES OPERATING COMPANY, 
INC., a Texas corporation, and SUMMIT PETROLEUM CORPORATION, a Colorado 
corporation (the "Borrower"), having an address at 616 FM 1960 West, Suite 
600, Houston, Texas, 77090-3027, promises to pay to the order of COMPASS BANK 
(herein called "Bank"), at its principal offices at 24 Greenway Plaza, 14th 
Floor, Houston, Harris County, Texas 77046, (i) the principal amount of 
THIRTY MILLION AND NO/100 DOLLARS ($30,000,000.00) or the principal amount 
advanced pursuant to the terms of the Loan Agreement (defined herein) as of 
the date of maturity hereof, whether by acceleration or otherwise, whichever 
may be the lesser, and (ii) interest on the principal balance from time to 
time advanced and remaining unpaid from the date of the advance until 
maturity at a rate of interest equal to lesser of (a) the "Interest Rate" (as 
defined in the Loan Agreement), or (b) the Maximum Rate (as hereinafter 
defined).  Any increase or decrease in interest rate resulting from a change 
in the Maximum Rate shall be effective immediately when such change becomes 
effective, without notice to Borrower, unless Applicable Law (as defined 
below) requires that such increase or decrease not be effective until a later 
time, in which event such increase or decrease shall be effective at the 
earliest time permitted under the provisions of such law.

     Notwithstanding the foregoing, if during any period the Interest Rate 
exceeds the Maximum Rate, the rate of interest in effect on this Note shall 
be limited to the Maximum Rate during each such period, but at all times 
thereafter the rate of interest in effect on this Note shall be the Maximum 
Rate until the total amount of interest accrued on this Note equals the total 
amount of interest which would have accrued hereon if the Floating Rate had 
at all times been in effect.

     All payments on this Note shall be applied first to accrued interest and 
the balance, if any, to principal.

     This Note is a revolving credit note and it is contemplated that by 
reason of prepayments hereon there may be times when no indebtedness is owing 
hereunder; but notwithstanding such occurrence, this Note shall remain valid 
and in full force and effect as to each principal advance made hereunder 
subsequent to each such occurrence.  Each principal advance and each payment 
hereof made pursuant to this Note shall be reflected by Bank's records and 
the aggregate unpaid amounts reflected by such records shall constitute 
rebuttably presumptive evidence of the principal and unpaid, accrued interest 
remaining outstanding on this Note.

     "Applicable Law" means that law in effect from time to time and 
applicable to this Note which lawfully permits the charging and collection of 
the highest permissible lawful, non-usurious rate of interest on this Note, 
including laws of the State of Texas and laws of the United States of 
America.  It is intended that Article 1.04, Title 79, Revised Civil Statutes 
of Texas, 1927, as amended (Article 5069-1.04, as amended, Vernon's Texas 
Civil Statutes) shall be included in the laws of the State of Texas in 
determining Applicable Law; and for the purpose of applying said Article 1.04 
to this Note, the interest ceiling applicable to this Note under said Article 
1.04 shall be the indicated weekly rate ceiling from time to time in effect.  
Borrower and Bank hereby agree that Chapter 15 of Subtitle 3, Title 79, 
Revised Civil Statutes of Texas, 1925, as amended, shall not apply to this 
Note or the loan transaction evidenced by, and referenced in, the Loan 
Agreement (hereinafter defined) in any manner, including without limitation, 
to any account or arrangement evidenced or created by, or provided for in, 
this Note.

     "Business Day" shall mean any day on which banks are open for general 
banking business in the State of Texas, other than a Saturday, a Sunday, a 
legal holiday or any other day on which banks in the State of Texas are 
required or authorized by law or executive order to close.

     The principal sum of this Note, after giving credit for unadvanced 
principal, if any, remaining at final maturity, shall be due and payable on 
or before the Maturity Date, as prescribed in the Loan Agreement defined 
below; interest to accrue upon the principal sum from time to time owing and 
unpaid hereunder shall be due and payable in monthly installments, as it 
accrues, with the first such monthly installment of interest hereon being due 
and payable on the first day of February 1998, and with such subsequent 
installments of interest being due and payable on the first day of each 
succeeding month thereafter; provided, however, the final installment of 
interest hereunder shall be due and payable not later than the maturity of 
the principal sum hereof, howsoever such maturity may be brought about.

     When the first (1st) day of a calendar month falls upon a Saturday, 
Sunday or legal holiday, the payment of interest and principal, if any, due 
upon such date shall be due and payable upon the next succeeding Business Day.

     In no event shall the aggregate of the interest on this Note, plus any 
other amounts paid in connection with the loan evidenced by this Note which 
would under Applicable Law be deemed "interest," ever exceed the maximum 
amount of interest which, under Applicable Law, could be lawfully charged on 
this Note. Bank and Borrower specifically intend and agree to limit 
contractually the interest payable on this Note to not more than an amount 
determined at the Maximum Rate.  Therefore, none of the terms of this Note or 
any other instruments pertaining to or securing this Note shall ever be 
construed to create a contract to pay interest at a rate in excess of the 
Maximum Rate, and neither Borrower nor any other party liable herefor shall 
ever be liable for interest in excess of that determined at the Maximum Rate, 
and the provisions of this paragraph shall

control over all provisions of this Note or of any other instruments 
pertaining to or securing this Note.  If any amount of interest taken or 
received by Bank shall be in excess of the maximum amount of interest which, 
under Applicable Law, could lawfully have been collected on this Note, then 
the excess shall be deemed to have been the result of a mathematical error by 
the parties hereto and shall be refunded promptly to Borrower.  All amounts 
paid or agreed to be paid in connection with the indebtedness evidenced by 
this Note which would under Applicable Law be deemed "Interest" shall, to the 
extent permitted by Applicable Law, be amortized, prorated, allocated and 
spread throughout the full term of this Note.

     This Note is secured by all security agreements, collateral assignments, 
mortgages and lien instruments executed by Borrower (or by any other party) 
in favor of Bank, including those executed simultaneously herewith, those 
executed heretofore and those hereafter executed, and including specifically 
and without limitation the "Security Instruments" described and defined in 
the Loan Agreement of even date between Borrower and Bank (the "Loan 
Agreement").

     This Note is the Revolving Note issued pursuant to the Loan Agreement. 
It amends, restates, rearranges and extends that certain promissory note 
dated October 31, 1996 in the face amount of $20,000,000.00, executed by 
Midland Resources, Inc. and payable to the order of First Union Bank of North 
Carolina ("First Union"), which has been assigned to Bank by First Union 
pursuant to an Assignment of Notes and Liens of even date herewith.  All 
liens and security interests held by or benefiting First Union to secure the 
indebtedness evidenced by such prior note have been assigned to Bank, and 
shall continue to secure the indebtedness evidenced by this Note.  Reference 
is hereby made to the Loan Agreement for a statement of the rights and 
obligations of the holder of this Note and the duties and obligations of 
Borrower in relation thereto; but neither this reference to the Loan 
Agreement nor any provisions thereof shall affect or impair the absolute and 
unconditional obligation of Borrower to pay any outstanding and unpaid 
principal of and interest on this Note when due, in accordance with the terms 
of the Loan Agreement.  Each advance and each payment made pursuant to this 
Note shall be reflected by notations made by Bank on its records and the 
aggregate unpaid amounts reflected by the notations on the records of Bank 
shall be deemed rebuttably presumptive evidence of the principal amount owing 
under this Note.

     In the event of default in the payment when due of any of the principal 
of or any interest on this Note, or in the event of default under the terms 
of the Loan Agreement or any of the Security Instruments, or if any event 
occurs or condition exists which authorizes the acceleration of the maturity 
of this Note under any agreement made by Borrower, Bank (or other holder of 
this Note) may, at its option, without presentment or demand or any notice to 
Borrower or any other person liable herefor, declare the unpaid principal 
balance of and accrued interest on this Note to be immediately due and 
payable.

     If this Note is collected by suit or through the Probate or Bankruptcy
Court, or any judicial proceeding, or if this Note is not paid at maturity,
however such maturity may be brought about, and is placed in the hands of an
attorney for collection, then Borrower agrees to pay reasonable attorneys' fees,

not be necessary for Bank, in order to enforce payment of this Note by them, 
to first institute suit or exhaust its remedies against any Borrower or 
others liable herefor, or to enforce its rights against any security herefor, 
and consent to any one or more extensions or postponements of time of payment 
of this Note on any terms or any other indulgences with respect hereto,

     following items are hereby expressly INCLUDED in Tangible Net Worth: (x)
     deferred taxes, and (y) those certain contracts and leases owned by
     Borrower and reflected on its consolidated balance sheet as the contracts

     II.  REAFFIRMATION OF REPRESENTATIONS AND WARRANTIES.  To induce the

     required), and do not and will not contravene or conflict with any
     provision of law or of the charter or by-laws of the Borrower or of any
     agreement binding upon Borrower.

     B.   This First Amendment represents the legal, valid and binding
     obligations of Borrower enforceable against Borrower in accordance with its
     terms subject as to enforcement only to bankruptcy, insolvency,
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally.

     C.   Since the date of the Credit Agreement, no change, event or state of
     affairs has occurred and is continuing which would constitute an Event of
     Default or an Unmatured Event of Default.

Agreement shall have the same meanings herein, unless the context otherwise 
requires.

     IV.  REAFFIRMATION OF CREDIT AGREEMENT.  This First Amendment shall be

     VII.  EXECUTION IN COUNTERPARTS.  This First Amendment may be executed

RESOURCES, INC. ("MRI"), a Texas corporation, MIDLAND RESOURCES OPERATING

Texas state chartered bank ("BANK") is executed on this 14th day of April, 1998,
to be effective, however, as of December 31, 1997.

                                 W I T N E S S E T H:

          Borrower and Bank entered into a Secured Reducing Revolving Credit
Agreement dated December 17, 1997, and a First Amendment thereto executed on
March 26, 1998 (collectively, the "Credit Agreement").

          Borrower has requested that Bank amend the Tangible Net Worth
Requirement, as set forth in Section 5.18 of the Credit Agreement, and Bank is
willing to enter into the requested amendment, subject to and conditioned upon
the provisions set forth herein.  

          NOW, THEREFORE, in consideration of the promises herein contained, and
each intending to be legally bound hereby, the parties agree as follows:

     I.   AMENDMENTS TO CREDIT AGREEMENT.

          ARTICLE I of the Credit Agreement is hereby amended by adding the
following defined terms:

               "FIRST AMENDMENT" means that certain First Amendment to this
          Agreement executed by Bank and Borrower on March 26, 1998.

               "SECOND AMENDMENT" means that certain Second Amendment to this
          Agreement executed by Bank and Borrower on April 14, 1998.

          SECTION 5.18 of the Credit Agreement is amended in its entirety to
read as follows:

               5.18 TANGIBLE NET WORTH REQUIREMENT.  Borrower shall maintain a
          total Tangible Net Worth of not less than $5,500,000.00, increasing
          by: (x) fifty percent 

<PAGE>

          (50%) of net income (excluding losses) of Borrower subsequent to 
          December 31, 1997, and (y) one hundred percent (100%) of any increases
          in shareholders' equity resulting from the sale or issuance of stock
          of any Borrower subsequent to December 31, 1997.

     II.  CERTAIN WAIVERS.  Bank hereby waives Borrower's non-compliance with
the provisions of Section 5.18 of the Credit Agreement, TANGIBLE NET WORTH
REQUIREMENT, for the quarter ending December 31, 1997.  This Second Amendment
shall not be deemed to be a waiver by Bank of any other covenant, condition or
obligation on the part of Borrower under the Credit Agreement, as hereby
amended, except as expressly set forth herein.  In addition, this Second
Amendment shall in no respect evidence any commitment by the Bank to grant any
future waivers of any covenant, condition or obligation on the part of Borrower
under the Credit Agreement, as hereby amended.  Any further waivers or consents
must be specifically agreed to in writing in accordance with Section 8.12 of the
Credit Agreement.
                    
     III. REAFFIRMATION OF REPRESENTATIONS AND WARRANTIES.  To induce the Bank
to enter into this Second Amendment, Borrower hereby reaffirms, as of the date
hereof, its representations and warranties contained in Article IV of the Credit
Agreement and in all other documents executed pursuant thereto, and additionally
represents and warrants as follows:

     A.   The execution and delivery of this Second Amendment and the
     performance by the Borrower of its obligations under this Second Amendment
     are within Borrower's power, have been duly authorized by all necessary
     corporate action, have received all necessary governmental approval (if any
     shall be required), and do not and will not contravene or conflict with any
     provision of law or of the charter or by-laws of the Borrower or of any
     agreement binding upon Borrower.

     B.   This Second Amendment represents the legal, valid and binding
     obligations of Borrower enforceable against Borrower in accordance with its
     terms subject as to enforcement only to bankruptcy, insolvency,
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally.

     C.   Since the date of the Credit Agreement, no change, event or state of
     affairs has occurred and is continuing which would constitute an Event of
     Default or an Unmatured Event of Default.

     IV.  DEFINED TERMS.  Terms used herein that are defined in the Credit
Agreement shall have the same meanings herein, unless the context otherwise
requires.

     V.   REAFFIRMATION OF CREDIT AGREEMENT.  This Second Amendment shall be
deemed to be an amendment to the Credit Agreement, and the Credit Agreement, as
amended hereby, is hereby ratified, adopted and confirmed in each and every
respect.

such dispute whether in federal or state court shall be laid in Harris County,

     VII.  SEVERABILITY.  Whenever possible each provision of this Second
Amendment shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Second Amendment shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Second Amendment.

     VIII. EXECUTION IN COUNTERPARTS.  This Second Amendment may be executed
in any number of counterparts and by the different parties on separate
