                      BARGO ENERGY COMPANY AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 1: THE COMPANY

Bargo Energy Company (the "Company" or "Bargo") is engaged primarily in the
acquisition, development and production of oil and gas reserves and operation of
oil and gas wells. The accompanying financial statements include the accounts of
the Company and its wholly owned subsidiaries, Bargo Petroleum Corporation (BPC)
and Future Cal-Tex Corporation (FCT). Intercompany accounts and transactions are
eliminated in consolidation. All material adjustments, consisting only of normal
recurring adjustments that, in the opinion of management are necessary for a
fair statement of the results for the interim periods, have been reflected.
These interim financial statements should be read in conjunction with the annual
consolidated financial statements of the Company.

On February 16, 2000, Bargo's wholly-owned subsidiaries and partnerships, Future
Energy Corporation (FEC), BMC Development No. 1, Ltd. (BMC), Future Acquisition
1995, Ltd. (FAQ) and NCI Shawnee Limited Partnership (NCI) merged into Future
Petroleum Corporation (FPC). In conjunction with the merger, the name of Future
Petroleum Corporation was changed to Bargo Petroleum Corporation. Additionally,
Alaska Eldorado Gold Company (AEG), a wholly owned dormant subsidiary of Bargo,
has been dissolved.

The preparation of the Company's financial statements in conformity with
generally accepted accounting principles requires the Company's management to
make estimates and assumptions that affect the amounts reported in these
financial statements and accompanying notes. Significant assumptions are
required in the valuation of proved oil and gas reserves which, as described
above, may affect the amounts at which oil and gas properties are recorded.
Actual results could differ from these estimates.

NOTE 2: PROPERTY ACQUISITIONS

On March 31, 2000, the Company acquired interests in oil and gas properties from
Texaco Exploration and Production, Inc., Four Star Oil and Gas Company and
McFarland Energy, Inc. ("Texaco Acquisition") for a gross purchase price of
$161.1 million, before closing adjustments. Such amount has been included as an
addition to oil and gas properties. The final determination of the purchase
price and its allocation is subject to adjustment over the current fiscal year.
The effective date of the purchase is January 1, 2000. The properties are
located in the Permian Basin, East Texas, Oklahoma and Kansas. The Company
utilized a new credit facility to acquire the properties (see Note 3.)

<PAGE>   8

The following Bargo Energy Company pro forma information gives effect to the
Texaco Acquisition referred to above and the East Texas properties (as reported
on Form 8-K filed on November 19, 1999) as if they had been acquired January 1,
1999:

NOTE 3: CREDIT AGREEMENT

Effective March 31, 2000, the Company entered into a new syndicated credit
agreement ("Credit Agreement") with Chase Bank of Texas ("Chase") and several
other energy lending banks (all banks shall be referred to collectively as the
"Banks"), with Chase serving as administrative agent. Proceeds from the new
Credit Agreement were used to fully refinance the Company's previous bank
indebtedness and make the Texaco Acquisition. Borrowings under the Credit
Agreement are secured by mortgages covering substantially all of the Company's
producing oil and gas properties. As required by the Credit Agreement, the
Company has hedged 75% of estimated oil production generated from the Texaco
Acquisition through 2001 (see Note 4). In accordance with the Credit Agreement
the Banks were paid various underwriting, administrative and advisory fees
totaling $4.38 million. The Credit Agreement provides for a total commitment
amount of $245 million, comprised of a revolving and a term facility.

The total commitment amount under the term facility is $45 million. The term
facility matures December 31, 2000. Borrowings under the term facility as of
March 31, 2000 were $45 million. The Company has received commitments from
several of its current stockholders to purchase preferred stock and has also
received a commitment from one of its lenders to convert a portion of the loan
into preferred stock, in an amount sufficient in the aggregate to repay the term
facility in full at maturity (see Note 5). The term facility bears interest
under the Base Rate plus an applicable margin of 2.0% or interest under the LIBO
Rate at the LIBO rate (reserve adjusted) plus 3.5%. The Company may convert any
portion of the outstanding debt from one interest rate type to another in
increments of $1 million. As the Company has both the ability and intent to
refinance its term facility, the amounts have been classified as long term in
the balance sheet at March 31, 2000.

<PAGE>   9

The total commitment amount under the revolving facility is $200 million with an
initial $160 million borrowing base ("Borrowing Base"). The revolving facility
matures March 31, 2003. Borrowings under the revolving facility as of March 31,
2000 were $123.65 million. Under the revolving facility, the Company has a
choice of two different interest rates; the Base Rate or the LIBO Rate. While
the term facility is outstanding, the debt under the revolving credit facility
bears interest under the Base Rate (which is the higher of the lender's "Prime
Rate" or the Federal Funds Rate plus .5%) plus an applicable margin of 1.0% or
interest under the LIBO Rate at the LIBO rate (reserve adjusted) plus 2.5%. The
Company may convert any portion of the outstanding debt from one interest rate
type to another in increments of $1 million. Upon repayment of the term
facility, the applicable margin is computed based on Borrowing Base utilization
ranging from 0%-.75% for Base Rate loans and 1.5%-2.25% for LIBO Rate loans.

In connection with the new Credit Agreement, the Company wrote off $1,696,000 of
loan costs related to the previously existing revolving credit agreement. Such
amounts are shown separately, net of tax, as an extraordinary item.

NOTE 4: HEDGING AND DERIVATIVE ACTIVITIES

The Company engages in certain hedging activities related to the purchase and
delivery of oil and gas in the future. Such activities are accounted for in
accordance with Statement of Financial Accounting Standard No. 80, "Accounting
for Futures Contracts" (SFAS 80). The losses on hedging contracts are included
as a reduction of net revenues.

In addition to the hedges in place at December 31, 1999, the Company entered
into additional derivative contracts in the first quarter of 2000 in relation to
the Texaco Acquisition. The instruments cover approximately 75% (or
approximately 190,000 BBLS per month) of estimated oil production related to the
Texaco Acquisition through calendar year 2001. The contracts related to the
Texaco Acquisition production consist of a floor of $22 per BBL for April
through December 2000 and a floor of $21 per BBL for January through December
2001. The Company was required to hedge a portion of its production under the
terms of their new Credit Agreement (see Note 3). Accordingly, the cost of the
instrument ($6.22 million, paid in full during the first quarter of 2000), has
been capitalized as loan costs and will be amortized over the three year term of
the revolving credit facility.

NOTE 5:  EQUITY BACKSTOP

The Company has received commitments from several of its current stockholders to
purchase preferred stock, and has also received a commitment from one of its
lenders ("Converting Lender") to convert a portion of the term facility into
preferred stock, in an amount sufficient in the aggregate to repay the term
facility (see Note 3) in full at maturity (the purchase of additional preferred
stock and conversion of a portion of the term facility into preferred stock in
order to retire the term facility at maturity shall be known as the "Equity
Backstop"). If the Equity Backstop is invoked, new common stock will also be
issued to the preferred shareholders and the Converting Lender. In order to
secure the Equity Backstop the Company paid an Equity Backstop fee of $1.35
million to the preferred stockholders and the Converting Lender. Additionally,
the Company initiated a Consent Action to increase the Company's outstanding
capital stock, in preparation for the potential issuance of additional shares as
a result of the Equity Backstop. This Consent Action was approved by a majority
of the Company's stockholders on March 13, 2000 and became effective April 10,
2000. The Company's articles of incorporation have been amended to increase the
authorized common shares to 200 million and authorized preferred shares to 10
million. It is the Company's intent to repay the term facility prior to its
maturity.

NOTE 6: EARNINGS PER SHARE

Net income or loss per common share is based on the weighted average number of
common shares outstanding. In accordance with SFAS 128, "Earnings Per Share,"
income available to common stockholders is reduced by the amount of dividends
on cumulative preferred stock and accretion of related stock issuance costs.
The Company's common stock equivalents consisted of stock options and warrants.

THE COMPANY

     Bargo Energy Company (the "Company" or "Bargo") is engaged in the
acquisition and exploitation of oil and natural gas properties located onshore
primarily in the Gulf Coast Region (Texas and Louisiana), Permian Basin,
MidContinent, and California. The Company's principal business strategies
include (i) maximizing the value of its existing high-quality, long-life
reserves through efficient operating and marketing practices, (ii) conducting
detailed field studies using the latest technology to identify additional
reserves and exploration potential, and (iii) seeking acquisitions of producing
properties, with exploration and development potential in areas where the
Company has operating experience and expertise. Bargo intends to continue its
efforts to aggressively grow the Company's resource base both through oil and
gas property acquisitions and corporate consolidations.


STRATEGIC DEVELOPMENTS

     On February 22, 2000, the Company agreed to purchase oil and gas properties
from subsidiaries of Texaco, Inc. for $161.1 million (the "Texaco acquisition").
The effective date of the purchase is January 1, 2000 and closing occurred on
March 31, 2000. The properties are located in the Permian Basin, East Texas,
Oklahoma and Kansas. Aggregate current net production from the properties totals
approximately 9,000 barrels of oil and 11 million cubic feet of gas per day.
Following the acquisition, Bargo has proven reserves of approximately 75 million
equivalent barrels of oil. The purchase price paid for the properties was
subject to reduction for the joint working interest owners exercise of
preferential rights to purchase certain properties and for title and other
environmental defects identified before closing.

     The Company received commitments from commercial banks to loan the Company
sufficient amounts to finance the entire acquisition and refinance existing bank
indebtedness. Up to $45 million of these loans will mature nine months following
the closing date. The Company has received commitments from several of its
current stockholders to purchase preferred stock, and has also received a
commitment from one of its lenders to convert a portion of the loan into
preferred stock, in an amount sufficient in the aggregate to repay this nine
month loan in full. These commitments to purchase preferred stock at maturity of
the nine-month loan also provide for the issuance of new common stock. The
Company intends to repay this loan from proceeds from asset sales and cash flow
prior to its maturity.

     On May 8, 2000 the Company entered into a contract to sell all of its
Ardmore Basin producing oil and gas properties in southern Oklahoma to Le Norman
Partners, LLC for $31.9 million, prior to closing adjustments. The effective

<PAGE>   11

date of the sale is May 1, 2000 and closing is expected to occur at the end of
May. Proceeds from this sale will be used to paydown existing indebtedness. In
addition, the Company intends to sell other non-core properties from the Texaco
acquisition, of which a portion of the proceeds would be available to repay the
term loan and revolving credit facility. The Company may also issue new debt or
equity securities to refinance part or all of the bank loans.


GENERAL

     The Company's revenues, profitability and future growth and the carrying
value of its oil and gas properties are substantially dependent on prevailing
prices of oil and gas and its ability to find, develop and acquire additional
oil and gas reserves that are economically recoverable. The Company's ability to
maintain or increase its borrowing capacity and to obtain additional capital on
attractive terms is also influenced by oil and gas prices.

     Prices for oil and gas are subject to large fluctuations in response to
relatively minor changes in the supply of and demand for oil and gas, market
uncertainty and a variety of additional factors beyond the control of the
Company. These factors include weather conditions in the United States, the
condition of the United States economy, the actions of the Organization of
Petroleum Exporting Countries, governmental regulation, political stability in
the Middle East and elsewhere, the foreign supply of crude oil and natural gas,
the price of foreign imports and the availability of alternate fuel sources. Any
substantial and extended decline in the price of crude oil or natural gas would
have an adverse effect on the Company's carrying value of its proved reserves,
borrowing capacity, revenues, profitability and cash flows from operations.

     The Company uses the full cost method of accounting for the Company's
investment in oil and gas properties. Under the full cost method of accounting,
all costs of acquisition, exploration and development of oil and gas reserves
are capitalized into a "full cost pool." Oil and gas properties in the pool,
plus estimated future expenditures to develop proved reserves and future
abandonment, site remediation and dismantlement costs, are depleted and charged
to operations using the unit of production method based on the portion of
current production to total estimated proved recoverable oil and gas reserves.
To the extent that such capitalized costs (net of depreciation, depletion and
amortization) exceed the discounted future net cash flows on an after-tax basis
of estimated proved oil and gas reserves, such excess costs are charged to
operations. Once incurred, the write down of oil and gas properties is not
reversible at a later date even if oil or natural gas prices increase.

     The Company does not have a specific acquisition budget because of the
unpredictability of the timing and size of forthcoming acquisition activities.
There is no assurance that the Company will be able to identify suitable
acquisition candidates in the future, or that the Company will be successful in
the acquisition of producing properties. In order to finance any possible future
acquisitions, the Company will either use borrowings available under the its
credit facility or the Company may seek to obtain additional debt or equity
financing in the public or private capital markets. Further, there can be no
assurances that any future acquisitions made by the Company will be integrated
successfully into the Company's operations or will achieve desired profitability
objectives.

     In June 1998 the Financial Accounting Standards Board issued SFAS 133"
Accounting for Derivative Instruments and Hedging Activities" (as amended by
SFAS 137). This standard is effective for fiscal years beginning after June 15,
2000 (January 1, 2001 for the Company). SFAS 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. The Company
has not yet completed its evaluation of the impact of the adoption of this new
standard.

     The Company implements oil and gas hedges as it deems appropriate to ensure
minimum levels of cash flow or as market conditions are believed to create an
opportunity to increase cash flows. At December 31, 1999 collars were in place
for portions of the Company's oil production for October 1 through September
2000 at floors of $18.00 and ceilings of $20.75 and $23.08. Contracted volumes
total 50,200 barrels per month declining each month to 42,000 barrels
representing approximately 14% of the Company's projected oil production.
Beginning October 2000 through September 2001 the Company has two swaps in place
at $17.55 and $18.05. Contracted volumes total 41,350 barrels per month
declining to 34,300 barrels per month representing approximately 13% of the
Company's projected oil production for that period.

     Floors are in place for April 2000 through December 2000 at a price of
$22.00 per bbl on 1,791,672 bbls. Additionally, the Company has secured a $21.00
per bbl floor for 2001 on a volume of 2,197,728 bbls. These floors protect
approximately 60% of the Company's current projected oil production.

     The Company currently has no outstanding natural gas hedges.


LIQUIDITY AND CAPITAL RESOURCES

     The Company's primary sources of capital are its cash flows from
operations, borrowings and issuance of debt and equity securities.

     The Company reported consolidated net income of $884,000 for the quarter
ended March 31, 2000 compared to a consolidated net loss of $961,000 for the
quarter ended March 31, 1999. At March 31, 2000, the Company had working capital
of $2,432,000, which was a $3,084,000 decrease from the $5,516,000 of working
capital that the Company had as of December 31, 1999. This decrease in working
capital was due primarily to increased accounts payable as of March 31, 2000.

     Effective March 31, 2000, the Company entered into a new credit agreement
with Chase Bank of Texas ("Chase")and several other energy lending bank, with
Chase serving as the administrative agent(the "Credit Agreement"). Borrowings
under the Credit Agreement are secured by mortgages covering substantially all
of the Company's producing oil and gas properties as well as by certain pledges
of the Company's Common Stock. The Credit Agreement provides a commitment amount
of $200 million and an initial $160 million borrowing base ("Borrowing Base").
In addition to the $200 million commitment, the Credit Agreement also provides
for a $45 million Term Loan which matures 9 months from the closing date. The
Company has received commitments from several of its current stockholders to
purchase preferred stock, and has also received a commitment from one of its
lenders to convert a portion of the loan into preferred stock, in an amount
sufficient in the aggregate to repay this nine month loan in full. These
commitments to purchase preferred stock at maturity of the nine-month loan also
provide for the issuance of new common stock.

     The Company has a choice of two different interest rates; the Base Rate or
the LIBO Rate. While the Term Loan is outstanding, the debt under the Borrowing
Base loan bears interest under the Base Rate (which is the higher of the
lender's "Prime Rate" or the Federal Funds Rate plus .5%) plus an applicable
margin of 1.0% or interest under the LIBO Rate at the LIBO rate (reserve
adjusted) plus 2.5%. The Term Loan bears interest under the Base Rate plus an
applicable margin of 2.0% and under the LIBO Rate plus 3.5%. The Company may
convert any portion of the outstanding debt from one interest rate type to
another in increments of $1,000,000 with a minimum transfer amount of
$1,000,000.

     As of March 31, 2000 borrowings under the Credit Agreement were $45 million
and $123.65 million for the term loan and the revolving credit facility,
respectively.

CASH FLOW TO OPERATING ACTIVITIES

     Operating activities of the Company during the three months ended March 31,
2000 provided net cash of $8,749,000. In the same period during 1999, operations
provided net cash of $214,000. Investing activities in the three months ended
March 31, 2000, used net cash of $143,529,000, primarily due to the Texaco
acquisition. Financing activities in the three months ended March 31, 2000
provided net cash of $135,733,000 primarily due to proceeds from the issuance of
debt in connection with the Texaco acquisition.


RESULTS OF OPERATIONS

Comparison of Quarters Ended March 31, 2000 and 1999.

     Production for the quarter ended March 31, 2000 increased by 289.4 MBOE, or
132%, to 507.8 MBOE versus the same period in 1999. This increased production is
due to two significant acquisitions made in May and October, 1999 which are not
included in the first quarter of 1999 operating results.

     Total revenues for the three months ended March 31, 2000 increased to
$10,805,000 from $2,201,000 for the same period in 1999, primarily due to an
increase in production from the Company's oil and gas property acquisitions.
This represents a 391% increase over 1999. Production costs increased from
$936,000 in the three months ended March 31, 1999 to $3,732,000 in the three
months ended March 31, 2000 due to the purchase of proved reserves. General and
administrative expenses increased to $1,013,000 from $863,000 in 1999 due to
overhead associated with the Company's increased acquisition activity. The
Company had net income of $884,000 for the three months ended March 31, 2000
compared to a net loss of $961,000 for the same period in 1999. Income before
income taxes and extraordinary items increased by $4,578,000 to $3,122,000 for
the three months ended March 31, 2000 compared to a net loss of $1,456,000 for
the comparable period in 1999. Interest expense for the three months ended March
31, 2000 was $925,000 compared to $871,000 for the same period in 1999.
Depreciation, depletion and amortization for the three months ended March 31,
2000 was $2,039,000. For the same period in 1999, the total was $991,000. This
increase is primarily a result of increased production volumes resulting from
the 1999 acquisitions.

INFLATION

     The Company's activities have not been, and in the near term are not
expected to be, materially affected by inflation or changing prices in general.
The Company's oil exploration and production activities are generally affected
by prevailing prices for oil.
