ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On November 26, 1997, Belco Oil & Gas Corp., a Nevada corporation ("Belco"),
completed the Merger (the "Merger") of its subsidiary Belco Acquisition Sub,
Inc., a Delaware corporation ("Belco Sub") with and into Coda Energy, Inc., a
Delaware corporation ("Coda"). The Merger was effected pursuant to the terms of
an Agreement and Plan of Merger, dated as of October 31, 1997, by and among
Belco, Belco Sub and Coda. In connection with the Merger, Belco paid an
aggregate of approximately $191 million in cash ($149 million plus a $42
million adjustment for proceeds from the Taurus disposition described below)
and issued warrants to purchase 1,666,667 shares of common stock, par value
$0.01 per share, of Belco (the "Belco Common Stock") to the holders of the
outstanding common stock, preferred stock and options to purchase common stock
of Coda. The warrants are exercisable for a period of two years commencing on
November 26, 1998 at an exercise price of $27.50 per share. The warrant
exercise price and the number of shares of Belco Common Stock that may be
issued pursuant to the exercise of the warrants will be adjusted to prevent
dilution in the event of stock splits, stock dividends and certain other events
affecting the capital structure of Belco.

The holders of Coda's common stock, preferred stock and options to acquire Coda
common stock who received consideration from Belco pursuant to the Merger
consisted of Joint Energy Development Investments Limited Partnership, a
Delaware limited partnership ("JEDI"), and members of Coda's management. The
consideration paid and issued by Belco in connection with the Merger was
determined by arms' length negotiations among Belco, Coda and certain
stockholders of Coda, including JEDI (the holder of 95% of the Coda common
stock, on a fully diluted basis, and 100% of the Coda preferred stock
outstanding immediately prior to the Merger). JEDI is a limited partnership
whose general partner is an affiliate of Enron Capital & Trade Resources Corp.,
a subsidiary of Enron Corp. ("Enron"). Mr. Robert A. Belfer, the Chairman of
the Board and Chief Executive Officer of Belco and the beneficial owner of
approximately 39% of the outstanding Belco Common Stock, is also a director of
Enron and the beneficial owner of approximately 2.36% of the common stock of
Enron (assuming full conversion of Preferred Convertible Stock of Enron held by
Mr. Belfer, family members and related trusts into shares of common stock of
Enron and including shares of common stock of Enron in which Mr. Belfer
disclaims beneficial interest).

   
On November 25, 1997 (prior to the Merger), Coda disposed of Taurus Energy
Corp. ("Taurus"), which was a subsidiary of Coda, to unrelated third parties
for $42 million in cash. The business and assets of Taurus consisted primarily
of two natural gas processing facilities and approximately 700 miles of related
gathering pipelines located in West Texas. Coda utilized such funds to repay
outstanding indebtedness under its bank credit facility. As a result of such
disposition, the cash portion of the Merger consideration was increased by the
amount of the cash consideration received by Coda in connection with the sale
of Taurus, resulting in the cash portion of the Merger Consideration being
approximately $191 million gross, $149 million net of the Taurus proceeds.
    

Concurrently with the Merger, Belco contributed $23 million to Coda that Coda
utilized, together with the funds from the Taurus disposition, to repay all of
the debt outstanding under Coda's revolving credit facility (approximately $65
million in principal amount), plus accrued interest thereon, at the time of the
Merger, and such credit facility was thereafter terminated. Belco funded the
cash portion of the Merger consideration and the cash contribution to Coda
through cash on hand and borrowings of $85 million under Belco's $150 million
revolving credit facility with a group of banks for which The Chase Manhattan
Bank acts as Administrative



<PAGE>   3

Agent (the "Belco Credit Facility"). In connection with the Merger, the Credit
Agreement related to the Belco Credit Facility was amended to (i) revise
certain restrictive covenants In order to permit the Merger to occur and (ii)
increased Belco's borrowing base from $50 million to $105 million (subject to
redetermination by the Administrative Agent from time to time).

   
As a result of the Merger, Coda will be required to make an offer to purchase
all of the $110 million in principal amount of its 10 1/2% Senior Subordinated
Notes, Series B, due 2006 (the "Coda Notes") currently outstanding at a price
equal to 101% of the principal amount of the Coda Notes plus accrued and unpaid
interest thereon. Notice of such offer was made on December 10, 1997 and such
offer expired January 9, 1998. $1 million principal amount of the Coda Notes
were purchased by Coda pursuant to such offer.
    

Coda is principally engaged in the acquisition and exploitation of oil and
natural gas properties. Coda's producing properties are concentrated in the
Permian Basin and the mid-continent region of the United States (primarily
Texas and Oklahoma). Coda's exploitation activities consist primarily of
secondary recovery operations, the drilling of development wells or infill
wells, workovers and recompletions in other productive zones.

Belco currently intends to continue to operate the oil and gas business of Coda
in substantially the same manner as currently conducted.

(b)  PRO FORMA FINANCIAL STATEMENTS

For Belco and Subsidiaries, attached hereto as Schedule C are the Unaudited Pro
Forma Consolidated Condensed Statements of Operations for the year ended
December 31, 1996 and for the nine-month period ended September 30, 1997, the
Unaudited Pro Forma Consolidated Condensed Balance Sheet as of September 30,
1997 and the Unaudited Pro Forma Supplemental Oil and Gas Disclosures as of
December 31, 1996.

   
The Pro Forma Financial Statements report pro forma oil and gas revenues
(unhedged) for the combined entities of $144.3 million for the nine month period
ended September 30, 1997. For the same period, pro forma volumes of natural gas
and oil production for the combined entities are reported at 40.4 Bcf and 3.15
MMBO (million barrels of oil), respectively. For the first nine months of 1997,
pro forma natural gas production represented approximately 63% of total
production on an Mcfe basis, with the remaining 37% represented by oil
production.

Belco will account for the acquisition of Coda using the purchase method of
accounting for business combinations. In accordance with the Statement of
Financial Accounting Standards Board No. 109 ("FASB 109"), Belco will record in
the fourth quarter ended December 31, 1997 a one-time non-cash deferred tax
liability of approximately $110 million to reflect the difference between the
tax basis of Coda's assets and liabilities and the amounts recorded for
financial reporting purposes for such assets and liabilities.

This FASB 109 "gross up" is reflected under Deferred Income Taxes in the
Liabilities column of Belco's Unaudited Pro Forma Balance Sheet as of September
30, 1997 included in this Form 8-K/A filing.

Belco will record in the fourth quarter ended December 31, 1997 a non-cash
ceiling test provision of approximately $150 million ($98 million after tax),
which is also reflected in the Unaudited Pro Forma Statements of Operations as
of September 30, 1997. The ceiling test provision includes the effect of the
non-cash $110 million FASB 109 "gross up" attributable to the Coda acquisition
on Belco's full cost pool at year end 1997 and adjustments to the SEC PV10 value
of year-end 1997 reserves, which were significantly impacted by lower product
prices when compared to year-end 1996 prices, among other items. The present
value of estimated future net revenues before income taxes of Belco's proved
reserves were $504 million as of December 31, 1997 (exclusive of price risk
management transactions) based on average prices of $17.28 per barrel of oil and
$2.30 per Mcf of natural gas. This compared to prices of approximately $25.13
per barrel of oil and $3.68 per Mcf of natural gas used in calculating year-end
1996 proved reserves.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS



The Board of Directors and Stockholders
Coda Energy, Inc.


We have audited the accompanying consolidated balance sheet of Coda Energy,
Inc., and subsidiaries (the "Successor") as of December 31, 1996, and the
related consolidated statements of operations, cash flows, and stockholders'
equity for the 319-day period from February 17, 1996 to December 31, 1996 and
the predecessor's consolidated balance sheet as of December 31, 1995 and its
related consolidated statements of operations, cash flows, and stockholders'
equity as described in Note 1 for each of the two years in the period ended
December 31, 1995. These financial statements are the responsibility of the
Successor's and the predecessor's management. Our responsibility is to express
an opinion on these consolidated 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 of the Successor referred
to above present fairly, in all material respects, the consolidated financial
position of Coda Energy, Inc., and subsidiaries at December 31, 1996, and the
consolidated results of their operations and their cash flows for the 319-day
period from February 17, 1996 to December 31, 1996, in conformity with
generally accepted accounting principles.

In our opinion, the consolidated financial statements of the predecessor
referred to above present fairly, in all material respects, the consolidated
financial position of the predecessor at December 31, 1995, and the
consolidated results of its operations and its cash flows for each of the two
years in the period ended December 31, 1995 in conformity with generally
accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  The Merger

    On February 16, 1996, pursuant to an Agreement and Plan of Merger dated as
    of October 30, 1995 (as amended, the "Merger Agreement"), by and among Coda
    Energy, Inc. ("Coda"), Joint Energy Development Investments Limited
    Partnership ("JEDI"), which is an affiliate of Enron Capital & Trade
    Resources Corp. ("ECT"), and Coda Acquisition, Inc. ("CAI"), which was a
    subsidiary of JEDI, JEDI acquired Coda through a merger (the "Merger") at a
    price of $7.75 per share in cash (for an aggregate purchase price of
    approximately $176.2 million). Coda together with its subsidiaries prior to
    and including February 16, 1996 is referred to herein as the Predecessor
    and after such date as CEI or Successor and collectively, for both periods
    the Company. Concurrently with the execution of the Merger Agreement, JEDI
    and CAI entered into certain agreements with--members of management (the
    "Management Group"), providing for a continuing role of management in the
    Company after the Merger. Following consummation of the Merger, the
    Management Group owns approximately 5% of Coda's common stock on a
    fully-diluted basis. JEDI owns the remaining 95%.

    The sources and uses of funds related to financing the Merger were as
    follows:

     (1) Represents indebtedness incurred by CAI and assumed by Coda to fund a
         portion of the consideration paid in the Merger.

    The Merger has been accounted for using the purchase method of accounting.
    As such, JEDI's acquisition cost has been allocated to the assets and
    liabilities acquired based on estimated fair values. As a result, the
    financial position and operating results subsequent to the date of the
    Merger reflect a new basis of accounting and are not comparable to prior
    periods. The allocation of JEDI's purchase price to the assets and 
    liabilities acquired resulted in a significant increase in the carrying 
    value of the oil and gas properties. Based upon the allocation of JEDI's 
    purchase price and estimated proved reserves and product prices in effect 
    at the date of the Merger, the purchase price allocated to oil and gas 
    properties was in excess of the cost center ceiling (see Note 2 - oil and 
    gas properties) by approximately $83.3 million ($53.3 million net of

    related deferred taxes). The resulting writedown was a non-cash charge and 
    has been included in the results of operations for the 319 days ended 
    December 31, 1996.

2.  Summary of significant accounting and reporting policies

    Principles of consolidation and basis of financial statement presentation -
    The consolidated financial statements include the accounts of Coda and its
    majority owned subsidiaries. All significant intercompany balances and
    transactions have been eliminated in consolidation. Certain
    reclassifications have been made to amounts reported in prior years to
    conform with the current presentation. All information contained herein
    concerning the 47-day period ended February 16, 1996 is unaudited.

    The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    disclosure of contingent assets and liabilities at the date of the
    financial statements and the reported amounts of revenues and expenses
    during the reporting period. Actual results could differ from these
    estimates.

    Cash and cash equivalents - Cash and cash equivalents include commercial
    paper or eurodollar investments with major financial institutions with
    maturities of three months or less when purchased.

    Accounts receivable - Substantially all accounts receivable arise from sales
    of oil, natural gas, or natural gas liquids or from participants in
    operated oil and gas wells. Generally, operators of oil and gas properties
    have the right to offset future revenues against unpaid charges related to
    operated wells. Oil and gas sales are generally unsecured. Most of the
    receivables are from a broad and diverse group of oil and gas companies
    and, accordingly, do not generally represent a significant credit risk.
    Credit losses, which have been insignificant, are provided for in the
    financial statements and have been within management's expectations.

    Oil and gas properties - Oil and gas properties are recorded at cost
    using the full cost method of accounting, as prescribed by the
    Securities and Exchange Commission (the "SEC"). Under the full cost method,
    all costs associated with the acquisition, exploration, or development of
    oil and gas properties are capitalized as part of the full cost pool.
    Sales, dispositions, and other oil and gas property retirements are
    accounted for as adjustments to the full cost pool, with no recognition of
    gain or loss unless such disposition would significantly alter the
    amortization rate. Under rules of the SEC for the full-cost method of
    accounting, the net carrying value of oil and gas properties is limited to
    the sum of the present value (10% discount rate) of estimated future net
    cash flows from proved reserves, based on period-end prices and costs, plus
    the lower of cost or estimated fair value of unproved properties (the "cost
    center ceiling").

    Depletion, depreciation, and amortization of evaluated oil and gas
    properties are provided using the unit-of-production method based on total
    proved reserves, as determined by independent petroleum reservoir
    engineers.

    Gas plants and gathering systems - Gas plants and gathering systems are
    recorded at cost and depreciated on a straight-line basis over the shorter
    of their estimated useful lives or 15 years.

                                      F-7

                       CODA ENERGY, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    
    Other properties and assets, net - Other assets include deferred financing
    costs, deferred gas contract costs and a receivable from a related party
    (see Note 13). Such costs are amortized over the life of the related loan
    agreements and contracts. Amortization of these costs for the 47-day period
    ended February 16, 1996 and the 319-day period ended December 31, 1996
    amounted to $68,000 and $660,000, respectively, which is included in
    depletion, depreciation, and amortization expense in the accompanying
    statements of operations.

    Overhead reimbursement fees - Fees from overhead charges billed to working
    interest owners, including the Company, of $3,372,000, $5,571,000,
    $848,000, and $6,011,000 for the years ended December 31, 1994, 1995, and
    the 47 days ended February 16, 1996 and 319 days ended December 31, 1996,
    respectively, have been classified as a reduction of general and
    administrative expenses in the accompanying consolidated statements of
    operations.

    Financial instruments - The Company enters into swap agreements to reduce
    the effects of the volatility of the price of crude oil and natural gas on
    the Company's operations. These agreements involve the receipt of fixed
    price amounts in exchange for variable payments based on NYMEX prices and
    specific volumes. The differential to be paid or received is accrued in the
    month of the related production and recognized as a component of oil and
    gas revenues.

    The Company also sells call options on crude oil. The strike price of these
    agreements exceeds current market prices at the time they are entered into.
    If the applicable market price exceeds the strike price and option premium,
    the differential is accrued and recognized as a reduction of oil revenues
    in the month of the related production. Any remaining deferred option
    premiums are recognized at the end of the option period.

    The fair values of the swap agreements and sold call options are not
    included in the accompanying consolidated balance sheet. See Note 11 for
    the estimated fair value of these financial instruments. Due to the short
    maturity, market sensitive interest rates and/or minimal changes in forward
    interest rates since the date of issuance, the carrying value of the
    Company's other financial instruments approximates fair value.

    New accounting pronouncements - In the first quarter of 1996, the Company
    adopted the Financial Accounting Standards Board ("FASB") Statement No. 121,
    "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
    Assets to be Disposed of" ("FAS 121"). Adoption of this statement did not
    have a material effect on the Company's financial statements.

    The FASB has issued its statement No. 123, "Accounting for Stock Based
    Compensation" ("FAS 123") which establishes an alternative method of
    accounting for stock based compensation to the method set forth in
    Accounting Principles Board Opinion No. 25 ("APB 25"). FAS 123 encourages,
    but does not require, adoption of a fair value based method of accounting
    for stock options and similar equity instruments granted to employees. The
    Company has elected to account for such grants under the provisions of APB
    No. 25.

    Pro forma information (unaudited) - The pro forma statement of operations
    information was prepared as if the Merger and the sale of the Notes (see
    Note 6) had occurred on January 1, of each 1995 and 1996. The pro forma
    information does not purport to represent the results of operations which
    would have occurred had such transactions been consummated on January 1,
    1995 and 1996 or for any future period. The pro forma information was
    prepared by adjusting the historical periods: (i) to adjust depletion,
    depreciation, and amortization to reflect JEDI's

    purchase price allocated to property and equipment, (ii) to adjust interest
    expense to give effect to the net reduction of approximately $37.0 million
    under the Company's credit facility, repayment of a note payable to an
    officer of the Company, and an increase in the interest rate on borrowings
    under the new credit facility of .25%, (iii) to record interest on the
    Notes at an interest rate of 10 1/2%, (iv) to record amortization of the
    issuance cost of the Notes over the term such debt is expected to be
    outstanding (10 years), (v) to adjust the writedown of oil and gas
    properties and stock option compensation in 1996 to eliminate these
    non-recurring charges related to the Merger, (vi) to adjust the provision
    for income taxes for the change in financial taxable income resulting from
    the above adjustments, (vii) to record the cumulative dividend requirements
    of the 15% cumulative preferred stock issued to JEDI.

3.  Predecessor merger with Diamond

    On September 30, 1994, pursuant to an Agreement and Plan of Merger, the
    Predecessor acquired all of the issued and outstanding stock of Diamond
    Energy Operating Company and Diamond A Inc. (collectively, "Diamond"). The
    Predecessor issued an aggregate of 3,647,715 shares of common stock to the
    Diamond stockholders. Contemporaneously with the merger, Diamond acquired
    the overriding royalty and reversionary interests owned by Diamond's
    primary lender in certain of Diamond's oil and gas properties for $9.0
    million cash. Coda provided the funds necessary to complete such
    acquisition and repay $18.5 million of existing Diamond indebtedness. If
    the price of oil received from the Diamond properties averages more than
    $17.65 per barrel for the 48-month period ending September 30, 1998,
    Diamond's former lender will be paid an additional $1.0 million. In
    addition, other reversionary interests in oil and gas properties in which
    Diamond owns an interest were purchased from certain employees, former
    employees, consultants and a financial advisor to Diamond for 634,519
    shares of common stock and approximately $39,000 in cash.

    The merger with Diamond was accounted for as a pooling of interests.
    Accordingly, the merger of the equity interests was given retroactive
    effect in these financial statements for periods prior to the merger to
    represent the combined financial statements of the previously separate
    entities. The acquisitions of the reversionary interests were accounted for
    as purchases effective September 30, 1994.

    Separate and combined results of the Predecessor and Diamond for periods
    prior to the merger were as follows (in thousands):

    In connection with the merger, the Predecessor incurred approximately $1.8
    million of legal, accounting, printing, and other costs related to the
    combination of the previously separate entities. Under pooling of interests
    accounting, these costs were expensed in September 1994.

4.  Other Predecessor Acquisitions

    The Company is continually acquiring oil and gas properties. The
    significant transactions that have occurred since January 1, 1994, are
    discussed below.

    On April 29, 1994, Coda acquired 100% of the issued and outstanding common
    stock of Taurus Energy Corporation ("Taurus"), a privately held Texas
    corporation, in exchange for 1,500,000 shares of the Predecessor's common
    stock, valued at approximately $7.3 million, and $3.25 million cash. The
    Predecessor assumed existing Taurus indebtedness of approximately $9.75
    million. Taurus operates three natural gas processing facilities and owns
    interests in approximately 700 miles of natural gas gathering systems
    located primarily in west central Texas.

    In July 1994, Taurus acquired ownership of the Shackelford gas gathering
    system and processing plant. Taurus had previously been operating the
    system and plant under operating leases. Taurus paid $3.8 million for the
    system and plant, which was funded under the existing credit agreement. In
    related transactions, Taurus entered into an agreement to sell 10,000 MMBTU
    per day to the former owner of Shackelford for a period of 48 months.
    Simultaneously, Taurus entered into a gas purchase agreement with an
    unrelated third party for similar quantities over the same term. Pricing
    under both the gas sales agreement and the gas purchase agreement is
    structured to allow Taurus to earn a margin on all volumes sold during the
    term of the agreements. In January 1995, Taurus acquired the remaining
    ownership interest in one of Taurus' gas plants and related facilities for
    $6.5 million.

    In December 1994, in two separate transactions, the Predecessor acquired
    interests in 31 producing oil and gas properties in West Texas from two
    major oil companies. The acquisition prices were $13.3Emillion and
    $10.0Emillion, respectively. The acquisitions were accounted for as
    purchases.

    In October 1995, the Predecessor acquired from Snyder Oil Company interests
    in 63 producing oil and gas properties located in West Texas (the "Snyder
    Properties"). The aggregate purchase price was $17.1 million in cash, of
    which $16.0 million was financed by borrowings under the existing credit
    facility. The acquisition was accounted for as a purchase.

    The following unaudited pro forma data present the consolidated results of
    operations of the Predecessor for the year ended December 31, 1995, as if
    the acquisition of the Snyder Properties had occurred on January 1, 1995.
    The pro forma results of operations are presented for comparative purposes
    only and are not necessarily indicative of the results that would have been
    obtained had such acquisitions been consummated as presented. The following
    data reflect pro forma adjustments for depletion, depreciation, and
    amortization related to the acquired oil and gas properties; adjustments to
    interest expense on borrowed funds; and resulting adjustments to income tax
    expense (in thousands).

    NationsBank credit agreements - Effective February 16, 1996, CEI entered
    into a credit agreement with NationsBank of Texas, N.A. ("NationsBank"), as
    lender and as agent, and additional lenders named therein (the "Credit
    Agreement"). The Credit Agreement is guaranteed by all of Coda's
    subsidiaries and provides for a revolving credit facility in an amount up
    to $250.0 million. The borrowing base is subject to redetermination: (i)
    semiannually, (ii) upon the sale of Taurus and (iii) upon issuance of
    public subordinated debt in an amount greater than $100.0 million. The
    lenders under the Credit Agreement agreed to waive their right to
    redetermine the borrowing base with respect to the issuance of the Notes
    (see Note 6). The borrowing base was redetermined effective July 1, 1996
    and remained at $115.0 million. At December 31, 1996, $64.5 million was
    outstanding under the Credit Agreement and $50.5 million was available for
    borrowing thereunder. The next redetermination of the borrowing base is
    scheduled for April 1, 1997.

    The Credit Agreement is unsecured. CEI has provided the lenders with first
    lien deeds of trust on its oil and natural gas assets which will not become
    effective, and the lenders have agreed not to file, unless (i) 80% of any
    outstanding borrowings in excess of the borrowing base is not repaid within

    So long as no default (as defined in the Credit Agreement) is continuing,
    CEI has the option of having all or any portion of the amount borrowed
    under the Credit Agreement be the subject of one of the following interest
    rates: (i) NationsBank's prime rate, (ii) the CD Rate plus 1 1/4% to 1 5/8%
    based upon the ratio of outstanding debt to the available borrowing base
    and (iii) LIBOR plus 1 1/4% to 1 5/8% based upon the ratio of outstanding
    debt to the available borrowing base. CEI must also pay a commitment fee of
    between 0.375% to 0.425% on the unused portion of the credit facility. The
    Credit Agreement contains various restrictive covenants, including
    limitations on the granting of liens, restrictions on the issuance of
    additional debt, restrictions on investments, a requirement to maintain
    positive working capital, and restrictions on dividends and stock
    repurchases. The Credit Agreement also contains requirements that JEDI or
    certain affiliates of JEDI must continue to own a majority of the
    outstanding equity of Coda and must have the ability to elect the majority
    of the Board of Directors and that certain members of management maintain
    specified levels of equity ownership in Coda and continue their employment
    with the Company. The Credit Agreement matures on February 16, 2001.

    On August 1, 1996, CEI entered into the First Amendment to Credit Agreement
    (the "First Amendment") which in general reduced the interest rate. The
    First Amendment provides CEI the option of having all or any portion of the
    amount borrowed under the Credit Agreement be the subject of one of the
    following interest rates: (i) NationsBank's prime rate, (ii) the CD Rate
    plus 1% to 1 1/2% based upon the ratio of outstanding debt to the available
    borrowing base and (iii) LIBOR plus 1% to 1 1/2% based upon the ratio of
    outstanding debt to the available borrowing base. CEI must also pay a
    commitment fee of between 0.30% to 0.425% on the unused portion of the
    credit facility.

    The Predecessor's credit agreement provided that interest rates on
    borrowings ranged from NationsBank's prime rate to LIBOR plus between 1%
    and 1 3/8% based on the ratio of outstanding debt to the available
    borrowing base. The weighted average interest rate on borrowings
    outstanding under the Credit Agreement was 7.43% and 6.91% for the year
    ended December 31, 1995 and for the 319-day period ended December 31, 1996,
    respectively.

    Note payable to NationsBank - The promissory note requires monthly
    principal and interest payments to January 2, 1998, with interest at
    NationsBank's prime rate.

    Senior subordinated debentures - The 12% Senior Subordinated Debentures
    (the "Debentures") are presented net of unamortized issuance discount of
    $165,000 at December 31, 1995. The effective interest rate on the
    Debentures is 16.61%. On May 1, 1996, CEI deposited with the trustee of the
    Debentures funds sufficient to redeem the Debentures at a redemption price
    of 100.0% of the principal amount of the Debentures plus accrued and unpaid
    interest thereon, and thereafter interest on the Debentures ceased to
    accrue.

    Scheduled maturities of long-term debt (including the Notes discussed in
    Note 6 below) as of December 31, 1996, are as follows (in thousands):

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    As a result of the long-term debt bearing interest at floating market rates
    and the minimal change in forward market interest rates from the time CEI
    completed the sale of the Notes (see Note 6), the carrying value of these
    financial instruments approximates fair value.

6.  10 1/2% Senior subordinated notes

    On March 18, 1996, CEI completed the sale of $110 million principal amount
    of 10 1/2% Senior Subordinated Notes due 2006 (the "Notes"). The proceeds
    of the Notes were used to fully repay the JEDI debt assumed in the Merger
    and to partially repay bank debt. The Notes bear interest at an annual rate
    of 10 1/2% payable semiannually in arrears on April 1 and October 1 of each
    year. The Notes are general, unsecured obligations of CEI, are subordinated
    in right of payment to all Senior Debt (as defined in the Indenture
    governing the Notes) of Coda, and are senior in right of payment to all
    future subordinated debt of CEI. The claims of the holders of the Notes are
    subordinated to Senior Debt, which, as of December 31, 1996, was $65.1
    million.

    The Notes were issued pursuant to an Indenture, which contains certain
    covenants that, among other things, limit the ability of Coda and its
    Restricted Subsidiaries (as defined in the Indenture) to incur additional
    indebtedness and issue Disqualified Stock (as defined in the Indenture),
    pay dividends, make distributions, make investments, make certain other
    restricted payments, enter into certain transactions with affiliates,
    dispose of certain assets, incur liens securing pari passu or subordinated
    indebtedness of Coda and engage in mergers and consolidations.

    The Notes are not redeemable by Coda's prior to April 1, 2001. After April
    1, 2001, the Notes will be subject to redemption at the option of Coda, in
    whole or in part, at the redemption prices set forth in the Indenture, plus
    accrued and unpaid interest thereon to the applicable redemption date. In
    addition, until March 12, 1999, up to $27.5 million in aggregate principal
    amount of Notes are redeemable, at the option of Coda on any one or more
    occasions from the net proceeds of an offering of common equity of Coda, at
    a price of 110.5% of the aggregate principal amount of the Notes, together
    with accrued and unpaid interest thereon to the date of the redemption;
    provided, however, that at least $82.5 million in aggregate principal
    amount of Notes must remain outstanding immediately after the occurrence of
    such redemption; provided, further, that any such redemption shall occur
    within 75 days of the date of the closing of such offering of common
    equity.

    In the event of a Change of Control (as defined in the Indenture), holders
    of the Notes will have the right to require Coda to repurchase their Notes,
    in whole or in part, at a price in cash equal to 101% of the aggregate
    principal amount thereof, plus accrued and unpaid interest thereon to the
    date of repurchase. The Indenture requires that, prior to such a repurchase
    but in any event within 90 days of such Change of Control, Coda must either
    repay all Senior Debt or obtain any required consent to such repurchase.


    Coda's payment obligations under the Notes are fully, unconditionally and
    jointly and severally guaranteed on a senior subordinated basis by all of
    Coda's current subsidiaries and future Restricted Subsidiaries. Such
    guarantees are subordinated to the guarantees of Senior Debt issued by the
    Guarantors (as defined in the Indenture) under the Credit Agreement and to
    other guarantees of Senior Debt issued in the future. All of Coda's current
    subsidiaries are wholly owned. There are currently no contractual
    restrictions on distributions from the Guarantors to Coda.

7.  Preferred Stock

    Under Coda's Restated Certificate of Incorporation, the Board of Directors
    is authorized to issue up to 40,000 shares of preferred stock, par value
    $0.01 per share. All 40,000 shares of preferred stock are designated as
    "15% Cumulative Preferred Stock," (the "Preferred Stock"). The holders of
    each share of Preferred Stock are entitled to receive, when and as declared
    by the Board of Directors, cumulative preferential dividends, at the rate
    of $150.00 per share per annum. There are currently 20,000 shares of
    Preferred Stock issued and outstanding. Shares of Preferred Stock in excess
    of such 20,000 shares shall be issuable only for the purpose of paying
    dividends on the Preferred Stock. As of December 31, 1996, the Preferred
    Stock had accumulated approximately $2.7 million in preferred dividends
    which had not been declared by the Board of Directors.

    As long as any shares of Preferred Stock are outstanding, no dividends
    whatsoever, whether paid in cash, stock or otherwise (except for dividends
    paid in shares of common stock, either in the form of a stock split or
    stock dividend), may be paid or declared, nor may any distribution be made,
    on any common stock to the holders of such stock, unless certain conditions
    are met.

    Coda's Restated Certificate of Incorporation requires that Coda redeem all
    the issued and outstanding shares of Preferred Stock at a redemption of
    $1,000 per share, plus all accrued and unpaid dividends (including
    undeclared dividends) to the date of redemption, if Coda has sufficient
    funds legally available for such redemption and if such redemption would
    not violate or

    conflict with any loan agreement, credit agreement, note agreement,
    indenture or other agreement relating to indebtedness to which Coda is a
    party, on or before the fifth business day after the earliest to occur of
    the following: (i) the closing of the sale by Coda of Taurus and (ii) a
    Trigger Event, as such term is defined in the Stockholders Agreement (see
    Note 13). The Preferred Stock may be redeemed by Coda at its option, as a
    whole or in part, to the extent Coda shall have funds legally available for
    such redemption, at any time or from time to time at a redemption price of
    $1,000 per share, plus all accrued and unpaid dividends (including
    undeclared dividends) to the date of redemption. Such redemption, whether
    required or optional, is restricted by the Credit Agreement and the
    Indenture.

    Upon the complete liquidation, dissolution, or winding up of Coda, whether
    voluntarily or involuntarily, the holders of Preferred Stock shall be
    entitled, after payment or provision for payment of the debts and other
    liabilities of Coda but before any distribution is made to the holders of
    any common stock, to be paid $1,000 per share plus all accrued and unpaid
    dividends (including undeclared dividends), and shall not be entitled to
    any further payment.

    Except as otherwise provided herein or required by law, the holders of
    shares of Preferred Stock are not entitled to vote on any matters to be
    voted on by the stockholders of Coda; provided, however, that so long as
    any shares of the Preferred Stock are outstanding, Coda shall not, without
    the written consent or the affirmative vote of holders of at least a
    majority of the total number of sharers of Preferred Stock then outstanding
    and voting as a class, (i) amend its Restated Certificate of Incorporation
    or Bylaws or (ii) authorize the merger (whether or not Coda is a surviving
    corporation in such merger) of Coda, in each case, if such amendment or
    merger would alter, change or abolish the powers, preference or rights of
    the Preferred Stock so as to affect the holders of the Preferred Stock
    adversely.

8.  Common equity

    Common stock - At December 31, 1995, the Predecessor had 40.0 million
    shares of $0.02 par value common stock authorized with 22.1 million shares 
    issued and outstanding. At December 31, 1996, CEI had 1.0 million shares of
    $0.01 par value common stock authorized with 13,611 shares issued to 
    management subject to put and call rights (see Note 13. Related Party 
    Transactions - Stockholders Agreement) and 900,000 issued to JEDI for a 
    total of 913,611 common shares issued and outstanding.

    Stock options and warrants - The Company has stock option plans providing
    for the granting of stock options to officers and key employees.
    Compensation expense has not been recognized at the time options are
    granted because the option price per share represents the market value of
    the share at the date of grant.

    The 1986 Non-Qualified Stock Option Plan provided that options may be
    granted, from time to time, to key employees and directors to purchase a
    maximum of 180,000 shares of common stock. This plan expired under its own
    terms during 1996. The 1989 Incentive Stock Option Plan provides that
    options may be granted, from time to time, to key employees to purchase a
    maximum of 750,000 shares of common stock. The 1993 Incentive Stock Option
    Plan permits the granting of options to purchase up to 1,500,000 shares of
    common stock.

    As a result of the Merger, all outstanding options and warrants were fully
    vested and the holders thereof were entitled to receive the difference
    between $7.75 per share and the exercise price for each share represented
    by the options and warrants, an aggregate of approximately $5.4 million.

    Additionally, certain members of the management of the Company exchanged
    their right to receive payment as it relates to options covering 164,375
    shares and warrants covering 700,000 shares with an aggregate value of
    approximately $3.2 million for an equity participation in CEI (the
    Replacement Options, Note 13). Such amount was recognized as stock option
    compensation expense in the 47-day period ended February 16, 1996. This
    equity participation took the form of options covering 31,989 CEI common
    shares with an exercise price of $.01, a 10-year term and immediately
    exercisable.

    The stock options outstanding at December 31, 1996, were not issued
    pursuant to any of the stock option plans. A certain number of shares could
    be reserved for issuance under the stock option plans in future periods;
    however, management does not presently expect any options to be granted
    pursuant thereto. See Note 13.

    The Company has elected to follow APB 25 in accounting for its employee
    stock options because, as discussed below, the alternative fair value
    accounting provided for under FAS 123 requires use of option valuation
    models that were not developed for use in valuing employee stock options.
    Generally, under APB 25, because the exercise price of the employee stock
    options equals the market price of the underlying stock on the date of
    grant, no compensation expense is recognized. The compensation expense
    recognized under APB 25 is due to changing the exercise price of the
    options in connection with the Merger.

    FAS 123 requires the use of the "minimum value" method for determining the
    value of employee stock options for nonpublic companies. This method
    estimates the value of the employee stock option as the excess of the fair
    value of the stock at the date of grant over the present value of both the
    exercise price and the expected dividend payments, each discounted at the
    risk-free rate, over the expected life of the option. FAS 123 generally
    requires the presentation of pro forma information as if employee stock
    options had been accounted for under FAS 123. However, due to the
    recognition of compensation expense under APB 25, at the date of the Merger
    and the absence of options grants subsequent thereto, the pro forma
    information would not be materially different from the historical results
    of operations.

9.  Employee benefit plan

    The Company sponsors a 401(k) defined contribution plan. The 401(k) plan is
    available to all employees who have at least six months of service. The
    Company matches between 50% and 100% (based on years of service) of an
    employee's contribution up to 6% of an employee's compensation. For the
    years ended December 31, 1994 and 1995, the 47 days ended February 16, 1996
    and the 319 days ended December 31, 1996, the Company 401(k) expense was
    $123,000, $252,000, $37,000 and $282,000, respectively, and is included in
    general and administrative expenses in the accompanying statements of
    operations.

10. Income taxes

    At December 31, 1996, Coda has net operating loss carryforwards ("NOLs")
    for income tax purposes that expire beginning in 1998. Utilization of the
    NOLs is severely restricted because of a change in ownership, as defined by
    the Tax Reform Act of 1986, of Coda, which occurred in March 1990. At
    December 31, 1996, Coda estimates that approximately $18.0 million of the
    NOLs is available to offset future taxable income without limitation, while
    the remainder will become available in the future at the rate of
    approximately $921,000 per year through 2004. Coda also has available
    statutory depletion carryforwards of approximately $1,000,000.

11. Operations
    

    Nature of Operations

    The Company is an independent energy company principally engaged in the
    acquisition and exploitation of producing oil and natural gas properties.
    The Company seeks to acquire properties whose predominant economic value is
    attributable to proved producing reserves and to enhance that value through
    control of operations, reduction of costs, and property development. The
    Company's producing properties are concentrated in the mid-continent region
    of the United States. Through a subsidiary, Taurus, the Company also
    operates natural gas processing and liquid extraction facilities and
    natural gas gathering systems.

(1) Includes approximately $320.5 million related to the Merger discussed in
    Note 1.

    All of the Company's oil and gas revenues are from proved developed
    properties located in the United States.

    The Company has capitalized internal costs of $712,000, $748,000, $105,000,
    and $567,000 for the years ended December 31, 1994, and 1995, the 47 days
    ended February 16, 1996, and the 319 days ended December 31, 1996,
    respectively. Such capitalized costs include salaries and related benefits
    of individuals directly involved in the Company's acquisition, exploration,
    and development activities based on the percentage of their time devoted to
    such activities.

    During the year ended December 31, 1994, sales of oil and gas to two
    purchasers accounted for 13% and 22% of consolidated gross revenue. During
    the year ended December 31, 1995, sales of

    oil and gas to two purchasers accounted for 10% and 18%, respectively, of
    consolidated gross revenue. During the 47 days ended February 16, 1996,
    sales of oil and gas to one purchaser accounted for 17% of consolidated
    gross revenue. During the 319 days ended December 31, 1996, sales of oil
    and gas to one purchaser accounted for 20% of consolidated gross revenue
    (an affiliate of Enron - see Note 13). Management believes that the loss of
    these purchasers would not have a material impact on the Company's
    consolidated financial condition or results of operations.

    Oil and Gas Hedging Activities and Commitments

    In an effort to reduce the effects of the volatility of the price of crude
    oil and natural gas on the Company's operations, management has adopted a
    policy of hedging oil and gas prices whenever such prices are in excess of
    the prices anticipated in the Company's operating budget and profit plan
    through the use of commodity futures, options, and swap agreements. The
    Company does not hold or issue financial instruments for trading purposes.

    While the use of these hedging arrangements limits the downside risk of
    adverse price movements, it may also limit future gains from favorable
    movements. All hedging is accomplished pursuant to exchange-traded
    contracts or master swap agreements based upon standard forms. The Company
    addresses market risk by selecting instruments whose value fluctuations
    correlate strongly with the underlying commodity being hedged. Credit risk
    related to hedging activities, which is minimal, is managed by requiring
    minimum credit standards for counterparties, periodic settlements, and
    market to market valuations. The Company has not historically been required
    to provide any significant amount of collateral relating to its hedging
    activities.

    At December 31, 1996, the Company had entered into various swap agreements
    to fix selling prices for crude oil at a weighted average NYMEX price of
    $19.13 per barrel for 735,000 barrels during 1997, certain of which are
    with affiliates of JEDI (see Note 13). The Company has also sold call
    options, which serve to limit the Company's oil price, covering 25,000
    barrels of oil per month at an option price of $20.00 per barrel for the
    period January 1997 to August 1997. In connection with two swaps beginning
    January 1, 1997 covering 10,000 barrels per month and 15,000 barrels per
    month at a strike price of $19.41 and $19.00, respectively, which expire
    June 30, 1997 and December 31, 1997, respectively, the Company granted the
    counterparty a one day option at the expiration of the swap to extend the
    swap for an additional twelve months. While these contracts have no
    carrying value in the accompanying balance sheet, their fair value (the
    estimated amount that would have been paid by the Company to terminate of
    the swaps) at December 31, 1996 was approximately $4.4 million. A one
    dollar change in the average NYMEX oil price (which was $25.92 at December
    31, 1996) would change the fair value by approximately $1.2 million.

    During the years ended December 31, 1994 and 1995, the 47 days ended
    February 16, 1996 and the 319 days ended December 31, 1996, oil and gas
    sales were reduced by $5,000, increased by $298,000, reduced by $14,000,
    and reduced by $3.1 million, respectively, as a result of hedging
    transactions.

12. Commitments and contingencies

    CEI does not believe that future costs related to site restoration,
    dismantlement, and abandonment costs, net of estimated salvage values, will
    have a significant effect on its results of operations or

    financial position because the salvage value of equipment and related
    facilities should approximate or exceed any future expenditures for
    restoration, dismantlement, or abandonment. The Company has not incurred
    any net expenditures for costs of this nature during the last three years.

    The Company is a defendant or co-defendant in minor lawsuits that have
    arisen in the ordinary course of business. In the lawsuits, management
    believes, based in part on advice from legal counsel, that the Company has
    meritorious defense against the claims asserted. Management believes that
    the ultimate resolution of the lawsuits and claims will not have a material
    adverse effect on results of operations or financial position.

    Subscription Agreement

    CAI entered into a Subscription Agreement dated as of October 30, 1995, as
    amended by Amendment No. 1 to Subscription Agreement dated as of January
    10, 1996, with members of the Management Group (as amended, the
    "Subscription Agreement") which provided for the acquisition by such
    persons of CAI common stock and the grant to them of nonqualified stock
    options to purchase shares of successor common stock (the "Replacement
    Options") of Coda. Under the Subscription Agreement, each member of the
    Management Group who acquired CAI common stock paid $100 per share for
    shares thereof, which is the same price per share paid by JEDI for the
    remaining shares of CAI common stock. Under the Subscription Agreement, the
    Management Group acquired CAI common stock immediately prior to the
    effective time of the Merger in exchange for varying combinations of (i)
    proceeds from limited recourse promissory notes payable to CAI in the
    aggregate principal amount of $937,300 (the "Promissory Notes"), (ii) Coda
    common stock, which was valued for this purpose at $7.75 per share, and
    (iii) cash. The CAI common stock so acquired was not registered under any
    federal or state securities laws and did not have the benefit of any
    registration rights, but was subject to the Stockholders Agreement
    described below. By virtue of the Merger, each share of CAI common stock
    was converted into one share of Coda common stock.

    The Promissory Notes are due on February 16, 2001, bear interest at 5.61%
    per annum, are secured by the common stock purchased with the proceeds
    thereof and certain rights of the maker under the Stockholders Agreement,
    and provide that in no event will an individual maker's liability
    thereunder for any deficiency on his respective Promissory Note (after the
    sale and disposition of all collateral securing same) exceed 35% of the
    original principal balance of the Promissory Note.

    The Subscription Agreement provided that the Specified Options
    (representing certain options to purchase common stock held by certain
    members of the Management Group) and Specified Warrants (representing
    certain warrants to purchase common stock held by certain members of the
    Management Group) would not be exercised prior to the effective time of the
    Merger and would, as of the effective time, be canceled without exercise
    and without payment of consideration. Concurrently, the Management Group
    entered into Nonstatutory Stock Option Agreements governing the Replacement
    Options that provided for the right for a period of 10 years from and after
    the effective time of the Merger to purchase shares of CEI common stock for
    $0.01 per share. However, the Replacement Options may only be exercised
    while the holder remains an

    employee and for a limited period of time thereafter. The number of shares
    of Coda common stock underlying the Replacement Options each member of the
    Management Group received is based on the amount of cash the holder would
    have received if his Specified Options or Specified Warrants had been
    converted into cash in the Merger on the same basis as other outstanding
    options and warrants to purchase common stock were converted, divided by
    the $100 per share purchase price paid by JEDI and the other Management
    Group members for their shares of CAI common stock. Thus, if the
    Replacement Options are exercised, the holders will have effectively paid
    the same purchase price per share as JEDI and the Management Group paid for
    their shares of common stock of Coda.

    In connection with the issuance of the Replacement Options, the Company
    recognized stock option compensation expense of approximately $3.2 million
    in the 47 days ended February 16, 1996 representing the total amount of
    cash the holders of the Specified Options and Specified Warrants would have
    received if such options and warrants had been converted to cash in the
    Merger.

    Stockholders Agreement

    CAI, JEDI and the Management Group entered into a Stockholders Agreement
    dated as of October 30, 1995, as amended by Amendment No. 1 to Stockholders
    Agreement dated as of January 10, 1996 (as amended, the "Stockholders
    Agreement"), which provides generally that all parties, including JEDI and
    the Management Group, (i) have rights of first refusal to acquire
    additional shares of common stock of Coda that may be issued by Coda and
    (ii) are restricted from transferring their Coda common stock. Coda has a
    right to match any third party offer to purchase shares of Coda common
    stock from any stockholder, and, in the event that Coda does not purchase
    those shares, the other stockholders may have a right to include a pro rata
    portion of their Coda common stock in the transaction. The Stockholders
    Agreement provides that, if the employment of a member of the Management
    Group terminates for any reason (including death or disability) other than
    his voluntary termination (except upon retirement at age 65 or older or the
    expiration of the term of any employment agreement he has with Coda) or his
    termination by Coda for cause, then Coda shall have a right to purchase
    such member's shares of Coda common stock (an aggregate of 13,611 shares at
    December 31, 1996) at a purchase price to be determined from time to time
    by Coda pursuant to a formula that values the shares on the basis of a
    comparison of the discretionary cash flow and EBITDA (as defined therein)
    of the Company and a group of peer companies. The Stockholders Agreement
    also provides that, if the employment of a member of the Management Group
    terminates for any reason other than voluntary termination or termination
    of such member for cause, then such member shall have the right to require
    Coda to purchase such member's shares of Coda common stock based on the
    previously described formula. The purchase price under the formula will
    vary depending on the financial performance of CEI and the group of peer
    companies.

    The Stockholders Agreement provides that each member of the Management
    Group shall have the right (the "Special Management Rights") to receive
    from JEDI, upon the occurrence of certain events (generally an initial
    public offering, a business combination with another person or the
    liquidation of Coda) (each, a "Trigger Event"), an amount, which is payable
    in cash or additional shares of Coda common stock depending upon the cause
    of the Trigger Event, designed to result in the Management Group receiving
    in connection with the Trigger Event one-third of the proceeds,
    attributable to the shares of Coda common stock purchased by JEDI, above
    the amount of proceeds necessary for JEDI to achieve an internal annual
    rate of return on that investment of 15%. The individual member's interest
    in such Special Management Rights is proportional to 

                                      F-24
<PAGE>   30


                      CODA ENERGY, INC. AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   

    such member's ownership of the fully diluted common stock of Coda. The
    Stockholders Agreement also provides that if the employment of a member of
    the Management Group terminates, his Special Management Rights shall
    terminate and, if the termination is other than a voluntary termination or
    a termination for cause, he may be entitled to receive an amount based on
    the discretionary cash flow and EBITDA formula discussed above. The
    Stockholders Agreement further provides that, after the effective time of
    the Merger, Coda will establish an employee benefit plan for the benefit of
    its employees who are not members of the Management Group and will
    contribute to the plan 1,900 shares of Coda common stock. Furthermore,
    pursuant to the Stockholders Agreement, 4% of the Special Management Rights
    will be allocated thereto.
    
    At September 30, 1996, the discretionary cash flow and EBITDA formula
    determines a theoretical value for Coda's common stock which indicates JEDI
    would have earned more than a 15% rate of return on its investments. The
    information to calculate the discretionary cash flow and EBITDA formula as
    of December 31, 1996, is not yet available. As determined by the
    discretionary cash flow and EBITDA formula, the value of the Special
    Management Rights to the Management Group in the aggregate was approximately
    $38 million at September 30, 1996. When a Trigger Event becomes probable,
    the Company will record compensation expense equal to the estimated value of
    the Special Management Rights at the time of such trigger event, which may
    be significantly different than the amount as of September 30, 1996. Since
    the Special Management Rights are an obligation of JEDI, the offsetting
    credit would be additional paid-in capital.
    

    The Stockholders Agreement will terminate and no party thereto will have
    any further obligations or rights thereunder upon the earliest to occur of
    (i) the termination of the Merger Agreement in accordance with its terms,
    (ii) October 30, 2005, (iii) the date on which an initial public offering
    of Coda common stock or any business transaction involving Coda whereby
    Coda common stock becomes a publicly traded security is consummated, (iv)
    the date of the dissolution, liquidation or winding-up of Coda and (v) the
    date of the delivery to Coda of a written termination notice executed by
    certain parties to the Stockholders Agreement.

    Enron

    Enron Corp. ("Enron") is the parent of ECT and accordingly may be deemed to
    control indirectly both JEDI and CEI. Enron and certain of its subsidiaries
    and other affiliates collectively participate in nearly all phases of the
    oil and natural gas industry and are, therefore, competitors of CEI. In
    addition, ECT and JEDI have provided, and may in the future provide, and
    ECT Securities Corp. has assisted, and may in the future assist, in
    arranging, financing to non-affiliated participants in the oil and natural
    gas industry who are or may become competitors of CEI. Because of these
    various conflicting interests, ECT, CEI, JEDI and the Management Group have
    entered into the Business Opportunity Agreement which is intended to make
    it clear that Enron and its affiliates have no duty to make business
    opportunities available to CEI in most circumstances. The Business
    Opportunity Agreement also provides that ECT and its affiliates may pursue
    certain business opportunities to the exclusion of CEI. The Business
    Opportunity Agreement may limit the business opportunities available to
    CEI. In addition, pursuant to the Business Opportunity Agreement there may
    be circumstances in which CEI will offer business opportunities to certain
    affiliates of Enron. If an Enron affiliate is offered such an opportunity
    and decides to pursue it, CEI may be unable to pursue it.

    Certain of Enron's affiliates purchase oil and gas from the Company.
    Management of the Company had determined that the contracts for sale of oil
    and gas to Enron affiliates have been entered into on terms no less
    favorable than those available from third parties after receiving

    competitive bids from third parties. Enron affiliates paid CEI
    approximately $24.1 million under such contracts for the 319 days ended
    December 31, 1996. Such amount is included in oil and gas revenue in the
    accompanying statement of operations.

    The Company has entered into two fixed price oil swaps with ECT. One swap
    covers the period from January 1, 1995 through June 30, 1997 at a strike
    price of $19.05 covering 15,000 barrels per month. The other covers the
    period from January 1, 1997 through December 31, 1997 at a strike price of
    $19.55 covering 10,000 barrels per month. Management of the Company had
    determined that both swaps were entered into on terms no less favorable
    than those available from third parties after receiving competitive bids
    from third parties. CEI paid ECT approximately $539,000 under such
    contracts for the 319 days ended December 31, 1996.

    During August 1996, Douglas H. Miller ("Miller"), the Company's Chief
    Executive Officer and Chairman of the Board of Directors, received $738,000
    pursuant to a Limited Recourse Promissory Note in the original principal
    amount of $1,188,000 (the "Miller Note"). The Miller Note bears interest at
    6.74% per annum with final maturity on February 16, 2001, and provides that
    in no event will Miller's liability thereunder (after the sale and
    disposition of all collateral securing same) exceed 35% of the original
    principal balance of the Miller Note. In connection with the execution of
    the Miller Note, CEI and Miller entered into an amendment of the agreement
    governing Miller's Replacement Option which prohibits the exercise of the
    option until all amounts due under the Miller Note have been paid in full.

14. Supplemental oil and gas reserve and standardized measure information
    (unaudited)
  
    The Company retains independent engineering firms to provide annual
    year-end estimates of the Company's future net recoverable oil, gas, and
    natural gas liquids reserves. Estimated proved net recoverable reserves as
    shown below include only those quantities that can be expected to be
    commercially recoverable at prices and costs in effect at the balance sheet
    dates under existing regulatory practices and with conventional equipment
    and operating methods. Proved developed reserves represent only those
    reserves expected to be recovered through existing wells. Proved
    undeveloped reserves include those reserves expected to be recovered from
    new wells on undrilled acreage or from existing wells on which a relatively
    major expenditure is required for recompletion.

    Reserve estimates are imprecise and may be expected to change as additional
    information becomes available. Furthermore, estimates of oil and gas
    reserves, of necessity, are projections based on engineering data, and
    there are uncertainties inherent in the interpretation of such data as well
    as the projection of future rates of production and the timing of
    development expenditures. Reserve engineering is a subjective process of
    estimating underground accumulations of oil and gas that cannot be measured
    in an exact way, and the accuracy of any reserve estimate is a function of
    the quality of available data and of engineering and geological
    interpretation and judgment. Accordingly, there can be no assurance that
    the reserves set forth herein will ultimately be produced nor can there be
    assurance that the proved undeveloped reserves will be developed within the
    periods anticipated. The Company emphasizes with respect to the estimates
    prepared by independent petroleum engineers that the discounted future net
    cash inflows should not be construed as representative of the fair market
    value of the proved oil and gas properties belonging to the Company, since
    discounted future net cash inflows are based upon projected cash inflows
    which do not provide for changes in oil and gas prices nor for escalation
    of expenses and capital

    accuracy of the assumptions upon which they were based.

    The following is a summary of a standardized measure of discounted net cash
    flows related to the Company's proved oil, gas, and natural gas liquids
    reserves. The information presented is based on a valuation of proved
    reserves using discounted cash flows based on year-end prices, costs, and
    economic conditions and a 10% discount rate exclusive of the effect of the
    oil hedging commitments. The additions to proved reserves from new
    discoveries and extensions could vary significantly from year to year;
    additionally, the impact of changes to reflect current prices and costs of
    reserves proved in prior years could also be significant. Accordingly, the
    information presented below should not be viewed as an estimate of the fair
    value of the Company's oil and gas properties, nor should it be considered
    indicative of any trends.

    During recent years, there have been significant fluctuations in the prices
    paid for crude oil in the world markets. This situation has had a
    destabilizing effect on crude oil's posted prices in the United States,
    including the posted prices paid by purchasers of the Company's crude oil.
    The weighted average prices of oil and gas at December 31, 1995, February
    16, 1996 and December 31, 1996 used in the above table, were $18.31, $17.92
    and $24.88 per Bbl, respectively, and $2.19, $2.01 and $3.53 per Mcf,
    respectively.

                      CODA ENERGY, INC. AND SUBSIDIARIES

             Notes to Consolidated Financial Statements (Unaudited)

1.   THE JEDI MERGER

  On February 16, 1996, pursuant to an Agreement and Plan of Merger, Coda
Energy, Inc. ("Coda"), was acquired by Joint Energy Development Investments
Limited Partnership ("JEDI"), which is an affiliate of Enron Capital & Trade
Resources Corp. ("ECT") (the "JEDI Merger"). Coda, together with its
subsidiaries, prior to and including February 16, 1996 is referred to herein as
the Predecessor and after such date as the Successor and collectively, for both
periods, the Company. In conjunction with the JEDI Merger, JEDI entered into
certain agreements with members of the Company's management (the "Management
Group"), providing for a continuing role of management in the Company after the
JEDI Merger. Following consummation of the JEDI Merger, the Management Group
owns approximately 5% of Coda's common stock on a fully-diluted basis. JEDI
owns the remaining 95%.

  The JEDI Merger has been accounted for using the purchase method of
accounting. As such, JEDI's cost of acquiring Coda has been allocated to the
assets and liabilities acquired based on estimated fair values. As a result,
the Company's financial position and operating results subsequent to the date
of the JEDI Merger reflect a new basis of accounting and are not comparable to
prior periods.

  The allocation of JEDI's purchase price to the assets and liabilities of Coda
resulted in a significant increase in the carrying value of the Company's oil
and gas properties. Under the full cost method of accounting, the carrying
value of oil and gas properties (net of related deferred taxes) is generally
not permitted to exceed the sum of the present value (10% discount rate) of
estimated future net cash flows (after tax) from proved reserves, based on
current prices and costs, plus the lower of cost or estimated fair value of
unproved properties (the "cost center ceiling"). Based upon the allocation of
JEDI's purchase price and estimated proved reserves and product prices in
effect at the date of the JEDI Merger, the purchase price allocated to oil and
gas properties was in excess of the cost center ceiling by approximately $83.3
million ($53.3 million net of related deferred taxes). The resulting writedown
was a non-cash charge and was included in the results of operations for the
227- day period ended September 30, 1996.

2.   ACCOUNTING AND REPORTING POLICIES

  The consolidated financial statements include the accounts of Coda and its
majority-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation. Certain reclassifications
have been made to prior years' amounts to conform to the current year
presentation.

  The accompanying consolidated financial statements, which should be read in
conjunction with the audited consolidated financial statements for the 319-day
period ended December 31, 1996,

                                       5
<PAGE>   41


reflect all adjustments (consisting only of normal recurring accruals) which
are, in the opinion of management, necessary to present fairly the financial
position as of September 30, 1997, and the results of operations and cash flows
for the 47-day period ended February 16, 1996, the 227-day period ended
September 30, 1996 and the nine months ended September 30, 1997. The results
for the period ended September 30, 1997, are not necessarily indicative of
results for a full year.

  Fees from overhead charges billed to working interest owners, including the
Company, of $848,000, $4.3 million and $4.9 million for the 47-day period ended
February 16, 1996, the 227-day period ended September 30, 1996 and the nine
months ended September 30, 1997, respectively, have been classified as a
reduction of general and administrative expenses in the accompanying
consolidated statements of operations.

3.   PRO FORMA INFORMATION

  The pro forma statement of operations information was prepared as if the JEDI
Merger and the sale of the 10 1/2% Senior Subordinated Notes (the "Notes") had
occurred on January 1, 1996. The pro forma information does not purport to
represent the results of operations which would have occurred had such
transactions been consummated on January 1, 1996 or for any future period. The
pro forma information was prepared by adjusting the 1996 periods: (i) to adjust
depletion, depreciation, and amortization to reflect JEDI's purchase price
allocated to property and equipment, (ii) to adjust interest expense to give
effect to the net reduction of approximately $37.0 million under the Company's
credit facility and repayment of a note payable to an officer of the Company,
partially offset by an increase in the interest rate on borrowings under the
new credit facility of .25%, (iii) to record interest on the Notes at an
interest rate of 10 1/2%, (iv) to record amortization of the issuance cost of
the Notes over the term such debt is expected to be outstanding (10 years), (v)
to adjust the writedown of oil and gas properties and stock option compensation
to eliminate these non-recurring charges related to the JEDI Merger, (vi) to
adjust the provision for income taxes for the change in financial taxable
income resulting from the above adjustments, and (vii) to record the cumulative
dividend requirements of the redeemable preferred stock issued to JEDI.

4.   ACQUISITIONS

  In February 1997, the Company purchased 123 producing oil and gas properties
from J. M. Huber Corporation for an aggregate purchase price of approximately
$13.5 million, of which $6.5 million was financed under the Company's credit
agreement. The properties are predominately located in Texas, Oklahoma and
Arkansas. The Company estimates the properties have proved reserves of
approximately 1.6 million barrels of oil and 15.1 Bcf of gas as of the
effective date, January 1, 1997.

5.   LONG-TERM DEBT

  On February 14, 1996, the Company entered into a credit agreement with
NationsBank of Texas, N.A. ("NationsBank"), as lender and as agent, and
additional lenders named therein (as amended, the "Credit Agreement") which
provides for a revolving credit facility in an amount up to $250.0 million.
Pursuant to the terms of the Credit Agreement, the semiannual borrowing base

                                       6

<PAGE>   42

redetermination as of April 1, 1997, resulted in an increase of the Company's
borrowing base from $115 million to $120 million. The next redetermination is
scheduled for January 1, 1998. At September 30, 1997, $67.0 million was
outstanding under the Credit Agreement and $53.0 million was available for
borrowing thereunder. On March 31, 1997, the Company repaid in full (principal
balance of $466,000) it's note payable to NationsBank that was due January 2,
1998.

6.   10 1/2% SENIOR SUBORDINATED NOTES

  On March 18, 1996, the Company completed the sale of the Notes which bear
interest at an annual rate of 10 1/2% payable semiannually in arrears on April
1 and October 1 of each year. The Notes are general, unsecured obligations of
the Company, are subordinated in right of payment to all Senior Debt (as
defined in the indenture governing the Notes (the "Indenture")) of Coda, and
are senior in right of payment to all future subordinated debt of the Company.
The claims of the holders of the Notes are subordinated to Senior Debt, which,
as of September 30, 1997, was $67.1 million.

  The Notes were issued pursuant to the Indenture, which contains certain
covenants that, among other things, limit the ability of Coda and its
Restricted Subsidiaries (as defined in the Indenture) to incur additional
indebtedness and issue Disqualified Stock (as defined in the Indenture), pay
dividends, make distributions, make investments, make certain other restricted
payments, enter into certain transactions with affiliates, dispose of certain
assets, incur liens securing pari passu or subordinated indebtedness of Coda
and engage in mergers and consolidations.

  Coda's payment obligations under the Notes are fully, unconditionally and
jointly and severally guaranteed on a senior subordinated basis by all of
Coda's current subsidiaries and future Restricted Subsidiaries. Such guarantees
are subordinated to the guarantees of Senior Debt issued by the Guarantors (as
defined in the Indenture) under the Credit Agreement and to other guarantees of
Senior Debt issued in the future. All of Coda's current subsidiaries are wholly
owned. There are currently no restrictions on distributions from the Guarantors
to Coda.

  Separate financial statements and other disclosures concerning the Guarantors
are not presented because management has determined they are not material to
investors. The combined condensed financial information of the Company's
current subsidiaries, the Guarantors, is as follows:

7.   PREFERRED STOCK

  Under Coda's Restated Certificate of Incorporation, the Board of Directors is
authorized to issue up to 40,000 shares of preferred stock, par value $0.01 per
share. All 40,000 shares of preferred stock are designated as "15% Cumulative
Preferred Stock" (the "Preferred Stock"). The holders of each share of
Preferred Stock are entitled to receive, when and as declared by the Board of
Directors, cumulative preferential dividends, at the rate of $150.00 per share
per annum. There are currently 20,000 shares of Preferred Stock issued and
outstanding. Shares of Preferred Stock in excess of such 20,000 shares are
issuable only for the purpose of paying dividends on the Preferred Stock. As of
September 30, 1997, the Preferred Stock had accumulated approximately $5.4
million in preferred dividends which had not been declared by the Board of
Directors.


8.   BELCO MERGER

  The Company entered into an Agreement and Plan of Merger (the "Belco Merger
Agreement") dated as of October 31, 1997 among the Company, Belco Oil & Gas
Corp., a Nevada corporation ("Belco"), and Belco Acquisition Sub, Inc., a
Delaware corporation ("Sub"), providing for the merger (the "Belco Merger") of
Sub with and into the Company, with the Company surviving the Belco Merger.
Pursuant to the terms and conditions of the Belco Merger Agreement, (i) the
common stockholders of the Company will receive an aggregate of $134 million in
cash, as increased by the cash proceeds, if any, received by the Company from
the sale of Taurus Energy Corp. ("Taurus"), a wholly owned subsidiary of the
Company, prior to the consummation of the Belco Merger, and as decreased by the
aggregate amount of payments due to Douglas H. Miller pursuant to the Amendment
to Executive Employment Agreement (discussed below), and (ii) the preferred
stockholder of the Company will receive (A) cash equal to the redemption value
of the Company's preferred stock less $10 million, (B) warrants to purchase
1,666,667 shares of common stock of Belco at an exercise price of $27.50 per
share (subject to adjustment), pursuant to the terms and conditions of a
Warrant Agreement to be executed and delivered to the Company's preferred
stockholder at the closing of the Belco Merger and (C) the right to receive
(only under certain circumstances) the aggregate amount received by the Company
from the sale of Taurus after the consummation of the Belco Merger.

  Prior to the closing of the Belco Merger, the Company has agreed, among other
things, to (i) operate its business in the ordinary course, consistent with
past practice, (ii) provide Belco full access to all of its properties and
personnel so as to enable Belco to conduct its due diligence, (iii) not
initiate, solicit, negotiate or encourage any proposal or offer to acquire all
or substantially all of the business of the Company, and (iv) use its
reasonable efforts to consummate a transaction disposing of Taurus.

  The Belco Merger Agreement provides for the closing of the Belco Merger on
November 26, 1997, which date can be extended to December 3, 1997 upon either
party's election. However, the closing of the Belco Merger is conditioned on a
number of things, including but not limited to, (i) Belco determining that, had
the Company's representations and warranties made in the Belco

                                       9

<PAGE>   45

Merger Agreement been made without any knowledge or materiality qualifiers,
Belco would not suffer or experience losses aggregating greater than $10
million and (ii) the execution and delivery of several ancillary agreements.

  The Belco Merger Agreement may be terminated (i) by mutual written consent of
Belco and the Company, (ii) by either Belco or the Company if the closing of
the Belco Merger has not occurred by November 26, 1997 (or December 3, 1997 if
either party has requested such extension in accordance with the Belco Merger
Agreement); provided that the Company cannot terminate the Belco Merger
Agreement pursuant to this clause (ii) for a period of 45 days after December
3, 1997 to allow Belco to obtain all regulatory approvals necessary to
consummate the transactions contemplated by the Belco Merger Agreement if the
disposition of Taurus does not occur before such date, or (iii) by either Belco
or the Company upon written notice to the other in the event of a final
permanent order either enjoining or otherwise prohibiting the consummation of
the transactions contemplated by the Belco Merger Agreement or having a
material adverse effect on the business, operations or financial condition of
Belco or the Company.

  Simultaneously with the execution of the Belco Merger Agreement, the Company
entered into a number of ancillary agreements. The Company entered into
Shareholder Agreements, effective as of October 31, 1997 (the "Shareholder
Agreements"), with Belco and each of the Company's minority shareholders
providing, among other things, that (i) the shareholder would vote in favor of
the Belco Merger at any meeting of stockholders and granting Belco an
irrevocable proxy, coupled with an interest, to vote in favor of the Belco
Merger, (ii) the shareholder waives any appraisal rights, and (iii) the
shareholder releases the Company from any claims that the shareholder might
have against the Company or any affiliate. The Company also entered into a
Stockholders Allocation Agreement dated as of October 31, 1997 (the "Allocation
Agreement") with all of the stockholders of the Company wherein the
stockholders, among other things, agreed to the allocation of the proceeds from
the Belco Merger among themselves and approved and adopted the Belco Merger
Agreement. The Company also entered into an Amendment to Executive Employment
Agreement dated as of October 31, 1997 with Douglas H. Miller providing, among
other things, for the cancellation of the remaining term under Mr. Miller's
original Executive Employment Agreement, effective upon the consummation of the
Belco Merger, and the payment to Mr. Miller at the closing of the Belco Merger
of the sum of all payments that would have come due to Mr. Miller under his
original employment agreement if Mr. Miller's employment had continued without
interruption.

  In connection with the JEDI Merger, JEDI and the Management Group entered
into a Stockholders Agreement dated October 31, 1995, as amended by Amendment
No. 1 to Stockholders Agreement dated as of January 10, 1996 (as amended, the
"JEDI Stockholders Agreement") that, among other things, provides that each
member of the Management Group shall have the right (the "Special Management
Rights") to receive from JEDI, upon the occurrence of certain events (generally
an initial public offering, a business combination with another person or the
liquidation of Coda) (each, a "Trigger Event"), an amount, which is payable in
cash or additional shares of Coda common stock depending upon the cause of the
Trigger Event, designed to result in the Management Group receiving in
connection with the Trigger Event one-third of the proceeds,

                                       10

<PAGE>   46

attributable to the shares of Coda common stock purchased by JEDI, above the
amount of proceeds necessary for JEDI to achieve an internal annual rate of
return on that investment of 15%. The individual member's interest in such
Special Management Rights is proportional to such member's ownership of the
fully diluted common stock of Coda. The Belco Merger would be a Trigger Event
as described in the JEDI Stockholders Agreement. If the Belco Merger is
consummated, the Company will record compensation expense equal to the value of
the Special Management Rights, currently estimated to range from $17.1 million
to $19.3 million. Since the Special Management Rights are an obligation of
JEDI, the offsetting credit would be to additional paid-in capital.

                     BELCO OIL & GAS CORP. AND SUBSIDIARIES

                   UNAUDITED PRO FORMA CONSOLIDATED CONDENSED
                              FINANCIAL STATEMENTS



The following unaudited consolidated condensed financial statements and related
notes are presented to show the pro forma effects of the merger of Coda Energy,
Inc. (Coda) with and into a wholly owned subsidiary of Belco Oil & Gas
Corporation (Belco).

The Coda transaction, hereinafter referred to as the "Merger", was completed
November 26, 1997 and will be reported using the purchase method of accounting.

The condensed statements of operations are presented to show income from
continuing operations as if the Merger occurred as of the beginning of the
respective periods. The pro forma condensed balance sheet is based on the
assumption that the merger occurred on September 30, 1997.

Belco will account for the acquisition of Coda using the purchase method of
accounting for business combinations. In accordance with the Statement of
Financial Accounting Standards Board No. 109 ("FASB 109"), Belco will record in
the fourth quarter ended December 31, 1997 a one-time non-cash deferred tax
liability of approximately $110 million to reflect the difference between the
tax basis of Coda's assets and liabilities and the amounts recorded for
financial reporting purposes for such assets and liabilities.

This FASB 109 "gross up" is reflected under Deferred Income Taxes in the
Liabilities column of Belco's Unaudited Pro Forma Balance Sheet as of September
30, 1997 included in this Form 8-K/A filing.


Belco will record in the fourth quarter ended December 31, 1997 a non-cash
ceiling test provision of approximately $150 million ($98 million after tax),
which is also reflected in the Unaudited Pro Forma Statements of Operations as
of September 30, 1997. The ceiling test provision includes the effect of the
non-cash $110 million FASB 109 "gross up" attributable to the Coda acquisition
on Belco's full cost pool at year-end 1997 and adjustments to the SEC PV10 value
of year-end 1997 reserves, which were significantly impacted by lower product
prices when compared to year-end 1996 prices, among other items. The present
value of estimated future net revenues before income taxes of Belco's proved
reserves were $504 million as of December 31, 1997 (exclusive of price risk
management transactions) based on average prices of $17.28 per barrel of oil and
$2.30 per Mcf. This compared to prices of approximately $25.13 per barrel of oil
and $3.68 per Mcf used in calculating year-end 1996 proved reserves.

Pro forma data is based on assumptions and include adjustments as explained in
the notes to the unaudited pro forma consolidated condensed financial
statements. The pro forma data is not necessarily indicative of the financial
results that would have occurred had the transactions been effective on and as
of the dates referenced above, and should not be viewed as indicative of
operations in future periods. The unaudited pro forma consolidated condensed
financial statements should be read in conjunction with the notes thereto,
Belco's Annual Report on Form 10-K for the fiscal year ended December 31, 1996,
Belco's Quarterly Reports on Form 10-Q for the quarters ended March 31, 1997,
June 30, 1997 and September 30, 1997, Coda's Annual Report on Form 10-K for the
fiscal year ended December 31, 1996, and Coda's Quarterly Reports on Form 10-Q
for the quarters ended March 31, 1997, June 30, 1997 and September 30, 1997.

                     BELCO OIL & GAS CORP. AND SUBSIDIARIES

    NOTES TO UNAUDITED PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

BASIS OF PRESENTATION

The unaudited pro forma consolidated condensed statements of operations
relative to the Merger are based on the audited historical financial statements
of Belco for the year ended December 31, 1996 and the audited historical
financial statements of Coda for the 319 days ended December 31, 1996 and
unaudited historical financial statements of Coda for the 47 days ended
February 16, 1996 and on the unaudited historical financial statements of Coda
and Belco for the nine months ended September 30, 1997. The pro forma
information relating to the Merger reflects the combination of Belco's and
Coda's historical results of operations, as adjusted to exclude the downstream
gas gathering and processing operations of Coda conducted through its
Subsidiary, Taurus Energy Corp. (Taurus). Differences in accounting policies
and methods between Belco and Coda were reviewed and considered to have an
immaterial impact on the combined pro forma financial results. Certain
historical Coda data have been reclassified to conform to Belco's historical
presentations.
 
PRO FORMA ADJUSTMENTS

       THE UNAUDITED PRO FORMA STATEMENTS OF OPERATIONS REFLECT THE FOLLOWING
ADJUSTMENTS:

       (a) Record interest expense and amortization of deferred financing costs
           associated with Belco's recent $150 million debt issuance. Interest
           expense was computed using an 8 7/8 percent rate on $150 million.

       (b) Adjust Coda historical to eliminate the effects of Coda's downstream
           operations conducted by Taurus, net of any intercompany allocations.
           The Taurus operations are not part of the Merger.

       (c) Record incremental DD&A Expense resulting from the merger.

       (d) Record pro forma income tax provision (benefit) relating to the pro
           forma adjustments assuming an effective federal and state rate of
           approximately 34 percent.

       (e) Record capitalized interest assuming, on a preliminary basis that
           $50 million of the purchase price is initially classified as
           unproved property costs and considering Belco's unproved property
           costs of $77.6 million and $83.3 million at December 31, 1996 and
           September 30, 1997, respectively, for which interest was not
           previously incurred or capitalized.

       (f) Adjust Coda historical to eliminate the effects of Taurus's general
           and administrative expenses, net of any intercompany allocations.

       (g) Record pro forma ceiling test provision of $150 million ($98 million
           after tax) on a consolidated basis at September 30, 1997 and remove
           the Coda stand alone December 31, 1996 ceiling test provision. The
           September 30, 1997 ceiling test provision includes the effect of the
           non-cash $110 million FASB 109 "gross up" attributable to the Coda
           acquisition on Belco's full cost pool at year-end 1997 and
           adjustments to the SEC PV 10 value of year-end 1997 reserves, which
           were significantly impacted by lower product prices when compared to
           year-end 1996 prices, among other items. 


    


<PAGE>   54

   
       (h) Record pro forma interest on credit line draw in connection with the
           merger using an assumed interest rate of 8 7/8 for the year ended
           December 31, 1996 and the nine months ended September 30, 1997,
           respectively. See (l) below.

       THE UNAUDITED PRO FORMA BALANCE SHEETS REFLECT THE FOLLOWING
       ADJUSTMENTS:

         (a)  Adjust historical combined preferred stock, common stock,
              paid-in capital and retained earnings, net of Taurus account
              balances to eliminate the historical carrying value of Coda's
              stockholders' equity. The impact of these entries does not result
              in a change to total combined stockholders' equity.

         (b)  Adjust Coda historical to eliminate the balances of Taurus
              operations. Taurus is not part of the Merger.

         (c)  Record assumed liabilities and transaction costs incurred in
              connection with the Merger.

         (d)  To eliminate Coda's historical balances, net of Taurus, as 
              applicable. See note (b).

         (e)  Record purchase price allocation as follows:

                  $ 422 million     Proved oil and gas property cost
                  $  27 million     Unproved oil and gas property costs
                  $   6 million     Building and other assets

         (f)  Record fair value of warrants issued in connection with the
              Merger.

         (g)  Record $149.9 million cash paid in connection with the purchase
              of Coda's common and preferred stock.

         (h)  Record deferred tax liability assumed in connection with the
              Merger.

         (i)  Record the pro forma receipt of cash received at closing from
              stockholders from subscription agreement.

         (j)  Record premium on 10 1/2 % Subordinated notes to
              reflect debt at fair market value.

         (k)  Record repayment of Coda's long-term bank debt, including $42
              million upon the Disposition of Taurus (see Note (b)).

         (l)  Record Belco's credit line draw in connection with the merger
              ($84 million) and excess cash from draw of $16.9 million.
     
         (m)  Record full cost impairment of proved oil and gas properties at
              September 30, 1997 as described in note (g) to the statement of

The following table sets forth unaudited pro forma information concerning the

of December 31, 1996, net of income tax expense, and giving effect to the
Merger as if the Merger had occurred on January 1, 1996. Income tax expense has
been computed using assumptions relating to the future tax rates and the
permanent differences and credits under the tax laws relating to oil and gas
activities at December 31, 1996, and do not take into account subsequent
changes in tax laws. The information should be viewed only as a form of
standardized disclosure concerning possible future cash flows that would result
under the assumptions used, and should not be viewed as indicative of fair
