(A TEXAS LIMITED LIABILITY COMPANY AND PREDECESSOR TO COSTILLA ENERGY, INC.)
                                          
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             SEPTEMBER 30, 1996
                                 (UNAUDITED)
                                           

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The interim financial information as of September 30, 1996, and for the 
nine months ended September 30, 1996 and 1995, is unaudited.  Certain 
information and footnote disclosures normally included in financial 
statements prepared in accordance with generally accepted accounting 
principles have been condensed or omitted in this Form 10-Q pursuant to the 
rules and regulations of the Securities and Exchange Commission.  However, in 
the opinion of management, these interim financial statements include all the 
necessary adjustments to fairly present the results of the interim periods 
and all such adjustments are of a normal recurring nature.  The interim 
consolidated financial statements should be read in conjunction with the 
audited financial statements for the year ended December 31, 1995.

    On October 8, 1996, Costilla Energy, Inc., a Delaware corporation formed 
in June, 1996 ("Costilla" or the "Company") to consolidate and continue the 
activities of the Costilla Energy, L.L.C. (the "LLC") consummated its initial 
public offering of common stock and completed the planned reorganization (see 
Note 5).  At that time, the LLC ceased to exist and its business activities 
are now being continued by the Company.

2.  DERIVATIVE FINANCIAL INSTRUMENTS

    The Company utilizes derivative financial instruments to manage 
well-defined interest rate and commodity price risks.  The Company is exposed 
to credit losses in the event of nonperformance by the counterparties to its 
interest rate swap agreements and its commodity hedges.  The Company 
anticipates, however, that such counterparties will be able to fully satisfy 
their obligations under the contracts.  The Company does not obtain 
collateral or other security to support financial instruments subject to 
credit risk but monitors the credit standing of the counterparties.

    COMMODITY HEDGES.  The Company utilizes option contracts to hedge the 
effect of price changes on future oil and gas production.  The following 
table sets forth the future volumes hedged by year and the strike price of 
the option contracts at September 30, 1996:

                             Oil          Gas

3.  ACQUISITION

    On June 14, 1996, the Company consummated the purchase from Parker and 
Parsley Petroleum Company of certain oil and gas properties for an estimated 
adjusted purchase price of approximately $42.5 million (the "1996 
Acquisition"). The properties are located primarily in south and west Texas.  
The transaction was accounted for using the purchase method.  The results of 
operations of the acquired properties are included in the Consolidated 
Statements of Operations as of the acquisition closing date, June 14, 1996.
    
    In June 1995 the Company acquired a group of oil and gas properties from 
Parker and Parsley Petroleum Company for approximately $46.6 million (the 
"1995 Acquisition").  The properties are located in the Permian Basin, Gulf 
Coast and Rocky Mountain regions.  The transaction was accounted for using 
the purchase method.  The results of operations of the acquired properties 
are included in the Consolidated Statements of Operations as of the 
acquisition date of June 12, 1995.

    PRO FORMA RESULTS OF OPERATIONS

    The following table reflects the pro forma results of operations for the 
nine months ended September 30, 1996 and 1995, as though the 1995 Acquisition 
and the 1996 Acquisition had each occurred as of January 1, 1995.  The pro 
forma amounts are not necessarily indicative of results that may be reported 
in the future.

4.  LONG-TERM DEBT

    On June 10, 1996, the Company entered into a new loan agreement with 
NationsBridge L.L.C. to provide financing of up to $125 million in advances 
(the "Bridge Facility"), subject to certain terms and conditions.  Proceeds 
of the Bridge Facility were used to fund the 1996 Acquisition, to refinance 
substantially all of the Company's outstanding indebtedness, and for other 
general corporate purposes.  Concurrently, the deferred charges associated 
with the 1995 Credit Agreement were expensed as an extraordinary loss.
    
    Advances under the Bridge Facility are to be made in two portions, 
Tranche A is up to $95,000,000 and Tranche B is $30,000,000.  Tranche A 
initially bears interest, at the Company's option, at the applicable prime 
rate ("Prime") plus 0.75% or LIBOR plus 3.0%.  Each margin above Prime and 
LIBOR increases by 0.50% at the end of each successive three-month period, up 
to maximum of 2.75% and 5.0% for Prime and LIBOR, respectively.  Tranche B 
initially bears interest at 14.00% per annum, increasing 0.50% at the end of 
each successive three-month period, up to a maximum of 16.5%.

    Tranche A loans are subject to a borrowing base determination.  The 
initial borrowing base is $95,000,000 which is automatically reduced by 
$3,000,000 per quarter beginning January 1, 1997.  The borrowing base is also 
subject to periodic redetermination by Nations Bridge L.L.C. based on its 
determination of the collateral value of the Company's oil and gas 
properties.  Final maturity of loans made under Tranches A and B is June 10, 
1999.


                                       7


    The Bridge Facility is secured by first priority liens, assignments, and 
security interests in substantially all oil and gas properties, pipelines and 
gathering systems of the Company and stock of the Company's subsidiaries. 
Additionally, the Bridge Facility are subject to various restrictive 
covenants and compliance requirements, including but not limited to (a) 
restrictions on dividends and the incurrence of additional indebtedness, (b) 
minimum limitations on the Company's current ratio and tangible net worth, 
(c) limitations on payments for leases and executive compensation, (d) 
maximum limitations on general and administrative expenses, capital 
expenditures, and the Company's ratio of debt to adjusted cash flow, and (e) 
a requirement to pay to the lender all net oil and gas revenues (as defined 
and as adjusted for capital expenditures) on a quarterly basis.

    The Company paid the lender's fees and expenses in connection with 
obtaining the Bridge Facility, which were approximately $3,250,000, and which 
are being amortized as additional interest expense over a period of one year 
from the date of the Bridge Facility. 

5.  SUBSEQUENT EVENTS

    INITIAL PUBLIC OFFERING AND NOTES OFFERING

    On October 2, 1996 the Company made an initial public offering and sold 
4,800,000 shares of Common Stock to the public at $12.50 per share and also 
issued $100,000,000 aggregate principal amount of 10 1/4% Senior Notes due 
2006 (collectively the "Offerings").  The net proceeds to the Company were 
approximately $151.5 million.  Approximately $125.8 million of such proceeds 
was used to repay all of the existing senior indebtedness.  In addition, 
$15.5 million of the net proceeds was used to redeem a membership interest in 
the LLC, $0.7 million was used to acquire the stock and assets of two 
affiliated companies, $3.5 million was distributed to three principals of the 
LLC for estimated federal income taxes, and $0.8 million was distributed to 
another LLC member.  The remaining $5.1 million will be used by the Company 
for general corporate purposes.  In addition, on November 1, 1996 the 
underwriters exercised a portion of the over-allotment option, granted to the 
underwriters in connection with the initial public offering, and purchased an 
additional 475,000 shares of Common Stock at $12.50 per share.  The 
additional net proceeds to the Company were approximately $5.5 million and 
will be used for general corporate purposes.

    BANK FINANCING

    In October 1996, the Company entered into a credit agreement (the "1996
Credit Facility") with NationsBank of Texas, N.A. (the "Bank").  The 1996 Credit
Facility provides a revolving line of credit with the availability of funds and
letters of credit being subject to a borrowing base determination at least
semiannually.  The borrowing base provides a maximum availability of $50.0
million (which amount is also the initial borrowing base), $500,000 of which was
outstanding at October 31, 1996.  Availability under the borrowing base is
initially limited to $20.0 million for working capital and $30.0 million for
acquisitions of oil and gas properties meeting certain criteria established by
the Bank.  Borrowings under the 1996 Credit Facility bear interest at the
Company's option at a floating rate which is at or above the NationsBank, N.A.
prime rate or the LIBOR rate, depending on the percentage of committed funds
which have been borrowed.  Interest is payable quarterly and principal will be
amortized in twelve equal installments commencing two years from the date of the
credit agreement.  Under the 1996 Credit Facility, the Company is obligated to
pay certain fees to the Bank, including a commitment fee based on the unused
portion of the commitment.  The 1996 Credit Facility contains customary
restrictive covenants (including restrictions on the payment of dividends and
the incurrence of additional indebtedness) and requires the Company to maintain
a current ratio of not less than 1.0 to 1.0, a ratio of Adjusted EBITDA to
interest expense of not less than 2.0 to 1.0 and a minimum tangible net worth. 
Borrowings under the 1996 Credit Facility are secured by substantially all of
the assets of the Company and any subsidiary of the Company that guarantees the
Company's obligations under the 1996 Credit Facility.  Initially, none of the
Company's subsidiaries have guaranteed the Company's obligations under the 1996
Credit Facility.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
         AND RESULTS OF OPERATIONS

GENERAL

    Costilla is an independent energy company engaged in the exploration, 
acquisition and development of oil and gas properties.  The Company's 
predecessor began operating in 1988 and through mid-1995 had grown primarily 
through a series of small acquisitions of oil and gas properties and the 
exploitation of those properties.  In June 1995, Costilla consummated the 
1995 Acquisition for a purchase price of approximately $46.6 million, and in 
June 1996, the 1996 Acquisition was consummated for a purchase price of 
approximately $42.5 million.

    To date, the Company has achieved its high rate of growth primarily 
through acquisitions.  This has impacted its reported financial results in a 
number of ways.  Properties sold by others frequently have not received 
focused attention prior to sale.  After acquisition, certain of these 
properties are in need of maintenance, workovers, recompletions and other 
remedial activity not constituting capital expenditures, which substantially 
increase lease operating expenses.  The increased production and revenue 
resulting from these expenditures is predominately realized in periods 
subsequent to the period of expense.  In addition, the rapid growth of the 
Company has required it to develop operating, accounting and administrative 
personnel compatible with its increased size.  The Company believes it has 
now achieved a sufficient size to expand its reserve base without a 
corresponding increase in its general and administrative expense.  The 
Company also believes it now has a sufficient inventory of prospects and the 
professional staff necessary to follow a more balanced program of exploration 
and exploitation activities to complement its acquisition efforts.

    Costilla's strategy is to increase its oil and gas reserves, production 
and cash flow from operations through a two-pronged approach which combines 
an active exploration program with the acquisition and exploitation of proved 
reserves.  In addition, Costilla continues to evaluate the acquisition of 
undeveloped acreage for its exploration efforts.  Costilla has in-house 
exploration expertise using 3-D seismic technology to identify new drilling 
opportunities as well as for the exploitation of acquired properties.

    Costilla has shown a significant increase in its oil and gas reserves and
production, especially due to the 1995 Acquisition and the 1996 Acquisition.

    Costilla uses the successful efforts method of accounting for its oil and 
gas activities.  Costs to acquire mineral interests in oil and gas 
properties, to drill and equip exploratory wells that result in proved 
reserves, and to drill and equip development wells are capitalized.  Costs to 
drill exploratory wells that do not result in proved reserves, geological, 
geophysical and seismic costs, and costs of carrying and retaining unproved 
properties are expensed. Capitalized costs of producing oil and gas 
properties, after considering estimated dismantlement and abandonment costs 
and estimated salvage values, are depreciated and depleted using the 
units-of-production method.  Unproved oil and gas properties that are 
individually significant are periodically reviewed for impairment of value, 
and a loss is recognized at the time of impairment by providing an impairment 
allowance.  Other unproved properties are amortized based on the Company's 
experience of successful drilling and average holding period.

    The Company utilizes option contracts to hedge the effect of price 
changes on a portion of its future oil and gas production.  Premiums paid and 
amounts receivable under the option contracts are amortized and accrued to 
oil and gas sales, respectively.  If market prices of oil and gas exceed the 
strike price of put options, the options will expire unexercised, therefore, 
reducing the effective price received for oil and gas sales by the cost  of 
the related option.  Conversely, if market prices of oil and gas decline 
below the strike price of put options, the options will be exercised, 
therefore, increasing the effective price received for oil and gas sale by 
the proceeds received from the related option.  The net effect of the 
Company's commodity hedging activities reduced oil and gas revenues by 
$563,000 for the three months ended September 30, 1996 and by $80,000 and 
$1,255,000 for the nine months ended September 30, 1995 and 1996, 
respectively.  There was no net effect from commodity hedging activities for 
the three months ended September 30, 1995.

    The Company utilizes interest rate swap agreements to reduce the 
potential impact of increases in interest rates on floating-rate, long term 
debt.  If market rates of interest experienced during the applicable swap 
term are below the rate of interest effectively fixed by the swap agreement, 
the rate of interest incurred by the Company will exceed the rate that would 
have been experienced under the Credit Agreement.  The net effect of the 
Company's interest rate hedging activities increased interest expense by 
$213,000 for the three months ended September 30, 1996 and $572,000 for the 
nine months ended September 30, 1996.

    The Company's predecessors were classified as partnerships for federal 
income tax purposes.  Therefore, no income taxes were paid or provided for by 
the company prior to the Offerings.  Future tax amounts, if any, will be 
dependent upon several factors, including but not limited to the Company's 
results of operations.

RECENT DEVELOPMENTS

    The Company's production for the three months ended September 30, 1996 was
an average of 10,337 BOE per day.  At October 31, 1996, the Company's average
daily production had increased to approximately 11,400 BOE per day, reflecting
the initial results of the Company's accelerated exploration and exploitation
program.  


    Financial results for the three months ended September 30, 1996 included 
the acquisition of properties in June 1996 from Parker & Parsley Petroleum 
Company for the full three month period and, therefore, is comparable to pro 
forma results as presented in the Company's  prospectus dated October 2, 1996.

    During the third quarter, lease operating costs excluding production 
taxes dropped to $5.46 per BOE, down from $5.81 for the six months ended June 
30, 1996, assuming the Company's June 1996 $42.5 million property acquisition 
from Parker & Parsley Petroleum Company occurred as of January 1, 1996.  
General and administrative expenses declined to $1.19 per BOE from $1.91 per 
BOE for the three months ended September 30, 1996 versus the comparable 
period in 1995.

including its Pennsylvania pipeline.  The Company anticipates that one or more
of these sales will be completed in the fourth quarter.


RESULTS OF OPERATIONS


THREE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO THREE MONTHS ENDED 
SEPTEMBER 30, 1995 

    The Company's total oil and gas revenues for the three months ended
September 30, 1996 were $15,343,000, an increase of $7,696,000 (101%) over
revenues of $7,646,000 for the comparable period in 1995.  This increase was
primarily due to the 1995 Acquisition and the 1996 Acquisition which accounted
for approximately $543,000 and $6,444,000 of the revenue increase, respectively.
The remainder of the increase was due to a combination of successful drilling
activities and the enhancement of existing production.  The average oil price
received in 1996 was $20.02 compared to $15.09 in 1995, a 33% increase, and the
average gas price received in 1996 was $1.96 compared to $1.37 in 1995, a 43%
increase.


    Oil and gas production was 951 MBOE in the 1996 period compared to 637 
MBOE in the 1995 period, an increase of 49%.  The 314 MBOE increase was
primarily composed of a 382 MBOE increase which was due to the properties
acquired in the 1996 Acquisition, offset in part by a decline in other
production.


    Interest and other revenues were $56,000 for the three months ended
September 30, 1996 compared to $14,000 for the comparable period in 1995,
representing an increase of $42,000, which was primarily comprised of an
increase in interest income of $26,000 in 1996 due to increased funds earning
interest.  Also in the 1996 period, the Company realized gains of $32,000 on
various transactions for which there were no comparable sales in 1995.



                                     11



    Oil and gas production costs in 1996 were $6,451,000 ($6.78 per BOE),
compared to $3,994,000 in 1995 ($6.27 per BOE), an increase of $2,457,000 (62%),
due principally to the 1996 Acquisition.  On a per BOE basis, production costs
increased $0.51 due primarily to higher production costs for the properties
acquired in that Acquisition.

    General and administrative expense for the three months ended September 30,
1996 was $1,132,000, representing an decrease of $86,000 (7%) from the
comparable period in 1995 of $1,218,000.  As noted above, production increased
49% and, therefore, general and administrative expenses per BOE decreased to
$1.19 per BOE for the three months ended September 30, 1996 from $1.91 per BOE
for the comparable 1995 period.

    Exploration and abandonment expense increased to $698,000 in the 1996
period compared to $230,000 in 1995.  The Company incurred $601,000 of seismic
costs for the three months ended September 30, 1996, compared to $467,000
incurred during the comparable period in 1995.  Dry hole and abandonment costs
increased from $2,000 to $97,000 for the comparable periods in 1995 and 1996,
respectively.

    Depreciation, depletion and amortization expense for the 1996 period was
$3,454,000 compared to $2,230,000 for the 1995 period, representing an increase
of $1,224,000 (55%).  During 1996, depreciation, depletion and amortization on
oil and gas production was provided at an average rate of $3.63 per BOE compared
to $3.50 per BOE for 1995.  The increase was due primarily to the 1996
Acquisition.

    Interest expense was $4,274,000 in the 1996 period, compared to $1,720,000
for the comparable period in 1995.  The $2,554,000 (148%) increase was
attributable primarily to increased levels of debt which the Company used to
finance the 1996 Acquisition.  The average amounts of applicable 
interest-bearing debt for the comparable periods in 1996 and 1995 were 
$124,651,000 and $74,576,000, respectively.  The effective annualized 
interest rate in 1996 was 13.7%, as compared to 9.2% in 1995.

NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO NINE MONTHS ENDED 
SEPTEMBER 30, 1995 

    The Company's total oil and gas revenues for the nine months ended
September 30, 1996 were $34,787,000, representing an increase of $21,572,000
(163%) over revenues of $13,215,000 for the comparable period in 1995.  This
increase was primarily due to the 1995 Acquisition and 1996 Acquisition, which
accounted for approximately $10,317,000 and $8,127,000 of the revenue increase,
respectively.  The remainder of the increase was due to a combination of
successful drilling activities and the enhancement of existing production.  The
average oil price received in 1996 was $18.92 compared to $15.51 in 1995, a 22%
increase in 1996, and the average gas price received in 1996 was $1.92 compared
to $1.41 in 1995, a 36% increase.

    Oil and gas production was 2,245 MBOE in the 1996 period compared to 1,076
MBOE in the 1995 period, an increase of 109%.  Of the 1,169 MBOE increase,
approximately 488 MBOE was due to the properties acquired in the 1996
Acquisition and 507 MBOE was due to the properties acquired in the 1995
Acquisition.  The remainder of the increase was due to a combination of
successful drilling activities and the enhancement of existing production.

    Interest and other revenues were $96,000 for the nine months ended
September 30, 1996 compared to $18,000 for the comparable period in 1995,
representing an increase of $78,000, which was primarily comprised of an
increase in interest income of $58,000 in 1996 due to increased funds earning
interest.  Also in the 1996 period, the Company realized gains of $73,000 on
various transactions for which no comparable sales were recorded in 1995.



                                     12



    Oil and gas production costs in the 1996 period were $14,729,000 ($6.56 per
BOE), compared to $6,407,000 in 1995 ($5.96 per BOE), representing an increase
of $8,322,000 (130%), due principally to the 1995 Acquisition.  On a per BOE
basis, production costs increased $0.60 due primarily to higher production costs
per BOE for the properties acquired in the 1996 Acquisition.


    General and administrative expenses for the nine months ended September 30,
1996 were $3,941,000, representing an increase of $1,715,000 (77%) from the
comparable period in 1995 of $2,226,000.  The increase is primarily due to an
increase in personnel and related costs necessary to accommodate the increased
activities of the Company due to the 1995 and 1996 Acquisitions.  However, as
noted above, production increased 109% and, therefore, general and
administrative expenses per BOE decreased to $1.76 per BOE for the nine months
ended September 30, 1996 from the $2.07 per BOE for the comparable 1995 period.

    Results of operations for the nine months ended September 30, 1995 include
non-cash compensation expense of $656,000 deemed to have been accrued to a
minority owner of the Company who was deemed to have benefited from the
cancellation of an option to purchase an additional interest held by the other
minority owner. 

    Exploration and abandonment expense decreased to $1,006,000 in the 1996
period compared to $1,237,000 in 1995.  The Company incurred $681,000 of seismic
costs for the nine months ended September 30, 1996, compared to $695,000 which
were incurred for the comparable period in 1995.  Dry hole and abandonment
costs decreased from $542,000 to $325,000 for the comparable periods in 1995
and 1996, respectively.

    Depreciation, depletion and amortization expense for the 1996 period was
$8,073,000 compared to $3,597,000 for the 1995 period, representing an increase
of $4,476,000 (124%).  During 1996, depreciation, depletion and amortization on
oil and gas production was provided at an average rate of $3.60 per BOE compared
to $3.34 per BOE for 1995.  The increase was due primarily to the 1996 and 1995
Acquisitions.

    Interest expense was $8,430,000 in the 1996 period, compared to $2,766,000
for the comparable period in 1995.  The $5,664,000 (205%) increase was
attributable primarily to increased levels of debt which the Company used to
finance the 1996 Acquisition.  The average amounts of applicable 
interest-bearing debt for the comparable periods in 1996 and 1995 were 
$93,429,000 and $41,742,000, respectively.  The effective annualized interest 
rate in 1996 was 11.5%, as compared to 8.8% in 1995.

    Results of operations for the nine months ended September 30, 1996 include
an extraordinary charge of $1,640,000 related to the early extinguishment of the
Company's prior bank credit facility (the "1995 Credit Facility").  The charge
consisted of previously capitalized debt issuance costs.  The 1995 Credit
Facility was replaced by the Bridge Facility outstanding at September 30, 1996.

LIQUIDITY AND CAPITAL RESOURCES

RECENT STOCK AND NOTES OFFERING

    The Company's liquidity and capital resources were improved significantly
when on October 2, 1996 the Company made an initial public offering and sold
4,800,000 shares of Common Stock to the public at $12.50 per share and also
issued $100,000,000 aggregate principal amount of 10 1/4% Senior Notes due 2006.
The net proceeds to the Company were approximately $151.5 million. Approximately
$125.8 million of such proceeds was used to repay all of the existing senior 
indebtedness.  In addition, $15.5 million of the net proceeds was used to 
redeem a membership interest in the predecessor LLC, $0.7 million was used to 
acquire the stock and assets of two affiliated companies, $3.5 million was 
distributed to three principals of the predecessor LLC for estimated federal 
income taxes, and $0.8 million was distributed to another LLC member. The 
remaining $5.1 million will be used by the Company for general corporate 
purposes.  In addition, on November 1, 1996 the underwriters exercised a 

                                     13



portion of the over-allotment option and purchased an additional 475,000 
shares of Common Stock at $12.50 per share.  The net proceeds to the Company 
were approximately $5.5 million and will be used for general corporate 
purposes.

NET CASH USED IN OPERATING ACTIVITIES

    For the nine months ended September 30, 1996, net cash provided by operating
activities increased to $4.6 million from $0.2 million for the comparable period
in 1995.  Cash provided by operations, before changes in operating assets and 
liabilities, increased to $7.8 million from $0.6 million for the comparable 
period in 1995 due primarily to the 1995 Acquisition and, to a lesser extent, 
the 1996 Acquisition, and the increase in results of operations therefrom.

NET CASH USED IN INVESTING ACTIVITIES

    Net cash used in investing activities for the nine months ended September
30, 1996 was $55.2 million.  Approximately $42.5 million was used for the 1996
Acquisition, $10.5 million was used for other oil and gas expenditures and $2.2
million was used for other property and equipment. 

NET CASH PROVIDED BY FINANCING ACTIVITIES

    The Company entered into the Bridge Facility in June 1996, against which
$125.0 million was borrowed at September 30, 1996.  Approximately $74.5 million
was for the extension and refinancing of prior debt, $42.5 million was used for
the 1996 Acquisition and approximately $8.0 million was used for general
corporate purposes.

CAPITAL SOURCES

    Funding for the Company's business activities has historically been
provided by bank financings, cash flow from operations, private equity sales,
property divestitures and joint ventures with industry participants.  The
Company completed a $10.0 million private equity placement in February 1995. 
Subsequently, the 1995 Acquisition and the 1996 Acquisition were substantially
funded by bank financings.  The Company plans to finance its continuing
operations and execute its business strategy with cash flow from operations, net
proceeds from the Offerings and borrowings under the Credit Facility.

    While the Company regularly engages in discussions relating to potential
acquisitions, the Company has no present agreement, commitment or understanding
with respect to any such acquisition, other than the acquisition of undeveloped
acreage and mineral interests in its normal course of business.  Any future
acquisition may require additional financing and will be dependent upon
financing arrangements available at the time.


    Concurrently with the closing of the Offering in October 1996, the Company
entered into the 1996 Credit Facility with the Bank.  The 1996 Credit Facility
provides a revolving line of credit with the availability of funds and letters
of credit being subject to a borrowing base determination at least semiannually.
The borrowing base provides a maximum availability of $50.0 million (which
amount is also the initial borrowing base), $500,000 of which was outstanding at
October 31, 1996.  Availability under the borrowing base is initially limited to
$20.0 million for working capital and $30.0 million for acquisitions of oil and
gas properties meeting certain criteria established by the Bank.  Borrowings
under the 1996 Credit Facility bear interest at the Company's option at a
floating rate which is at or above the NationsBank, N.A. prime rate or the LIBOR
rate, depending on the percentage of committed funds which have been borrowed. 
Interest is payable quarterly and principal will be amortized in twelve equal
installments commencing two years from the date of the credit agreement.  Under
the 1996 Credit Facility, the Company is obligated to pay certain fees to the
Bank, including a commitment fee based on the unused portion of the commitment. 
The 1996 Credit Facility contains customary restrictive covenants (including
restrictions on the payment of dividends and the incurrence of additional
indebtedness) and requires the 



                                     14



Company to maintain a current ratio of not less than 1.0 to 1.0, a ratio of 
Adjusted EBITDA to interest expense of not less than 2.0 to 1.0 and a minimum 
tangible net worth.  Borrowings under the 1996 Credit Facility are secured by 
substantially all of the assets of the Company and any subsidiary of the 
Company that guarantees the Company's obligations under the 1996 Credit 
Facility.  Initially, none of the Company's subsidiaries have guaranteed the 
Company's obligations under the 1996 Credit Facility. 

    The Company believes that cash on hand, cash flow from operations and funds
available under the 1996 Credit Facility will be sufficient for anticipated
operating and capital expenditure requirements.  However, because future cash
flows and the availability of financing are subject to a number of variables
beyond the Company's control, there can be no assurance that the Company's
capital resources will be sufficient to maintain currently planned levels of
capital expenditures.

CAPITAL EXPENDITURES

    The Company requires capital primarily for the exploration, development and
acquisition of oil and gas properties, the repayment of indebtedness and general
working capital needs.

    The Company anticipates that costs incurred for 1996 for acquisition,
exploration and development activities will be approximately $64.8 million. 
During the nine months ended September 30, 1996, approximately $42.5 million was
expended for the 1996 Acquisition and approximately $11.0 million was expended
on exploration and development activities.  The Company anticipates spending the
remaining $11.3 million in the fourth quarter for exploration and development
activities. 

DELIVERY COMMITMENT

    In November 1995, the Company entered into gas sales agreements whereby it
committed delivery of a total of 2,379,000 Mmbtu, from December 1, 1995 through
December 1, 1996, for a total fixed price of $3,429,610.  Income from the
agreements is recognized in the period of delivery.
