Item 2 ACQUISITION OR DISPOSITION OF ASSETS


        On November 4, 1997, NRG Energy, Inc., ("NRG") acquired 100% of the
outstanding shares of Pacific Generation Company ("PGC"), an indirect 
wholly-owned indirect subsidiary of PacifiCorp for a cash purchase price of 
$148.6 million.  The consideration paid by NRG was comprised of working capital
funds, and funds drawn from NRG's $175 million Revolving Credit Facility with a
syndicate of banks led by ABN-AMRO. NRG was selected to acquire the PGC shares
pursuant to a private auction conducted by PGC's sole shareholder, PacifiCorp
Holdings, Inc. and its investment banker, Goldman Sachs & Co.  PGC has
ownership interest in 11 projects with a total capacity of 737 MW, with
operational responsibility for 312 MW and net ownership interests of 166 MW. 
Moreover, PGC owns a limited partnership interest in Energy Investors Funds,
through which it owns an additional allocated share equal to 39MW.
        
        One of PGC's projects is located in Canada and the other ten are located
throughout the United States.  The three largest projects are gas-fired, but
the others are fueled by coal, hydro, waste wood, refuse-derived fuel and wind. 
One sells only steam, while the other ten have power sales agreements with a
total of seven different utilities.  PGC serves a variety of roles in these
facilities, ranging from operator/manager of three projects, including its
largest asset, Crockett Cogeneration, to a limited partner in other projects.

        Crockett Cogeneration.  PGC is the sole general partner in and the
operator of the 240 MW Crockett Cogeneration project ("Crockett"), which
commenced operations in May 1996. PGC also holds a 23.87% limited partnership
interest in Crockett through ENI Crockett, LP, a limited partnership in which
Destec is a 25.27% limited partner.  The project sells 240 MW of capacity and
electric power to Pacific Gas & Electric Company ("PG&E") under a power
purchase agreement ("PPA") extending to 2026.  The PPA provides for a fixed
capacity payment and a variable energy payment based on the market price of
gas.   In addition, Crockett provides up to 450,000 lbs./hr. of steam to the
C&H Sugar refinery under a steam sales agreement that does not expire until
2026. Natural gas is supplied to the project by Amoco Canada Marketing Corp.
under a fifteen year contract, with performance guaranteed by Amoco Canada
Petroleum Company Ltd. PGC operates the project under a 15-year contract that
provides for reimbursement of all costs within an approved budget, plus a fee
and the possibility of a performance bonus.
        
        PGC holds the sole one percent general partnership interest in 
Crockett as well as a 23.87% limited partnership interest, which will increase
to 56.68% after certain conditions of payment to the other limited partners
have been satisfied.  Those partners are the Energy Investors Fund and Tomen
Investments.  Crockett was financed with a $278 million construction and term
loan facility provided by a commercial bank syndicate led by ABN-AMRO, which
will mature on December 31, 2010.

        Kingston Cogeneration.  Kingston, the only PGC project located outside
of the United States, is a 110 MW combined cycle gas turbine project in
Ontario, Canada.  The project commenced operation in 1996.  It sells power to
Ontario Hydro under a 20-year, which provides for a fixed capacity payment and
a variable energy payment, provided the plant meets certain operating targets.
Up to 150,000 lbs./hr. of thermal energy is sold to Hoechst-Celanese and gas is
supplied under a 20-year agreement with PanCanadian Petroleum Limited.

        PGC has a 25% general partnership interest in this project, though the
project is operated by AES.  The project was financed with a C$193.6 million
construction and term loan led by Bank of Nova Scotia and Credit Suisse, which
will mature in March 2013.

     PowerSmith Cogeneration.  The PowerSmith Cogeneration project is a 110
MW combined cycle gas turbine project.  Smith Cogeneration is the managing
general partner of the project and General Electric is the operator.  The
PowerSmith project sells its power to Oklahoma Gas and Electric  under a
contract expiring in 2004, and sells its steam to Dayton Tire for the same 
term.  PGC has a total of 8.75% general and limited partnership interests in 
this project until 2003, which is decreased automatically to a 6.25% ownership 
interest thereafter.
        
     Maine Energy Recovery Project ("MERC").  MERC is a 680 ton per day
waste-to-energy facility located in Biddeford, Maine.  The annual throughput of
municipal solid waste is approximately 200,000 tons and income is received from
the disposal or "tipping" fees paid by communities utilizing this service.  The
facility sells its 22 MW output to Central Maine Power under a 20-year PPA,
which was restructured in May 1996 to provide for energy-only rates until 2007,
after which all sales will be at market-based capacity and energy rates.  The
new PPA also extended its term through 2012.

     PGC owns a 16.25% limited partnership interest in MERC with no operating
responsibilities.  All of the senior debt on the project was repaid with funds
received from the renegotiation of the PPA but there is still some
subordinated debt outstanding to certain partners (including PGC) in the amount
of $14.1 million.

     Penobscot Energy Recovery Project ("PERC").  PERC is an 800 ton per day
waste-to-energy facility located in Orrington, Maine, which began operations in
1988.  The minimum annual throughput is approximately 175,000 tons under a
series of agreements with Maine communities that pay "tipping" fees for waste
disposal services.  The project's 22 MW electric power output is sold to Bangor
Hydroelectric Company pursuant to a 30-year PPA.  PERC, Bangor Hydro and the
affected communities have reached an agreement in principle to restructure the
terms of this PPA and are seeking the approvals required to do so.  If
approved, this restructuring is expected to result, among other things, in a
substantial cash payment to PERC from the utility.

     PGC owns 28.7% of the general and limited partnership interests in
PERC and NRG has become the operator of the project under the terms of the
acquisition.  PERC was financed with $108.6 million of tax-exempt bonds,
supported by a letter of credit from Bankers Trust.  It is expected that this
financing would be replaced by bonds issued by the Finance Authority of Maine
as a part of the restructuring of the PPA.

Mt. Poso Cogeneration Facility.  Mt. Poso is one of two coal-fired
cogeneration plants in which PGC has an ownership interest.  It is a 49.5 MW
circulating fluidized bed facility located near Bakersfield, California.  The
project sells electricity to PG&E under a standard offer contract which extends
to 2009.  The standard offer contract requires PG&E to make fixed energy
payments to the project for capacity and energy for a period of 10 years.  Upon
termination of the fixed energy payment period on April 1, 1999, PG&E is
obligated to pay for all electricity deliveries at its full short-run avoided
operating costs.  Thus,  there can be no assurances concerning the likely
income from this project following April 1, 1999. The project also supplies up
to 45,000lbs./hr. of steam to an adjacent oil field owned by the project for
enhanced oil recovery.  Coal has been supplied to the project by ARCO Coal
Company and the project recently renegotiated the terms of that contract.
        
     PGC owns a 21.50% general partnership interest in Mt. Poso itself, and in
addition, owns a 47.5% interest in the company that operates the project,
Pyro-Pacific Operating Company.

     Turners Falls Cogeneration.  The second PGC coal-fired cogeneration
facility, Turners Falls, is in cold shut-down as a result of a PPA Termination
Agreement entered into in 1996 at the request of the power purchaser, Unitil
Power Company.  Turners Falls is a 20.1 MW coal-fired facility that had been
placed into service in 1989.  Under the terms of the PPA Termination Agreement,
Unitil will make monthly payments to Turners Falls until 2009, and the project
must be ready to resume operations on six months notice.  PGC owns an 8.9%
limited partnership interest in Turners Falls.

     Wind Power Partners.  The wind projects consist of one 50 MW project (500
wind turbines) and one 30 MW project (300 wind turbines), both located in
California.  PGC has a one percent general partnership interest in each
project, and a 16% and a 17.54% limited partnership interest in them,




                                      3

respectively.  Power is sold from both projects to PG&E under five 30-year
standard offer contracts. Each of the standard offer contracts obligate PG&E to
make a fixed payment for capacity and energy for a period of 10 years. Although
the fixed payment period has terminated for certain of the Wind Power standard
offer contracts, all remaining Wind Power standard offer contract fixed payment
periods will expire on or before February, 1998. After the  expiration of fixed
payment period, power is sold at PG&E's short-run avoided cost rate with a
reduced capacity payment.  PGC also owns half of the $7.6 million senior debt
on the 50 MW project and all of the $4.4 million senior debt on the 30 MW
project.

     Curtis Palmer Hydroelectric Project.  Curtis Palmer is the only hydro
electric project in the PGC portfolio.  It is a 58 MW project located at two
dams on the Hudson River near the town of Corinth, New York.  The project
recently entered into a renegotiated PPA with Niagara
Mohawk  Power Corp. for a term that is projected to expire in 2027.  PGC has
only an 8.5% limited partnership interest in this project.

     Camus Power Boiler. The Camas project is a 200,000 lbs./hr. wood and
natural gas fired boiler which supplies steam to the Fort James Paper Mill in
Camas, Washington. Under the Steam Sales Agreement, which expires in 2007, Fort
James makes fixed and variable payments to Camas in exchange for the steam
supply.  The project  does not generate electricity or make any power sales,
but its steams sales  are the equivalent of 25 MW of electric power.

     PGC owns 100% of the Camas project, but Fort James has an 
option to buy the project at various prices determined in accordance with the 
Agreement during its term.  The project was financed with $15 million of 
tax-exempt bonds and $22.8 million in taxable debt, all supported by a letter 
of credit from HelebaBank.

INDEPENDENT AUDITORS' REPORT

Pacific Generation Company:

We have audited the accompanying consolidated balance sheets of Pacific
Generation Company and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholder's equity and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We did not audit the
financial statements of Energy Investors Fund, Energy Investors Fund III, Maine
Energy Recovery Company, Mt. Poso Cogeneration Company, Penobscot Energy
Recovery Company, and Powersmith Cogeneration Company (the "Investments").
These Investments are accounted for by use of the equity method. The Company's
equity in the Investments of $41,475,924 and $40,485,965 at December 31, 1996
and 1995, respectively, is included in Investments In and Advances to
Partnerships and earnings of $10,861,449 and $5,810,088 for the respective
years then ended are included in Equity in Income from Partnerships, all
included in the accompanying financial statements. The financial statements of
the Investments were audited by other auditors whose reports have been
furnished to us, and our opinion, insofar as it relates to the amounts included
for the Investments, are based solely on the reports of such other auditors.

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 and the reports of the other
auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the reports of the other auditors, such
consolidated financial statements present fairly, in all material respects, the
financial position of Pacific Generation Company and subsidiaries at December
31, 1996 and 1995, and the results of their operations and their cash flows for
the years then ended in conformity with generally accepted accounting
principles.

PACIFIC GENERATION COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1996 AND 1995
(IN THOUSANDS OF DOLLARS)
- --------------------------------------------------------------------------------

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   ORGANIZATION AND BUSINESS - Pacific Generation Company (the "Company"), was
   incorporated in August 1984 for the purpose of developing, building, owning,
   operating, and managing energy production facilities. The Company is a
   wholly-owned subsidiary of PacifiCorp Holdings, Inc. ("Holdings"), which is
   a wholly-owned subsidiary of PacifiCorp.

   SALE OF THE COMPANY - In 1997, Holdings decided to sell the Company as part
   of a larger PacifiCorp decision to sell certain assets deemed not to be core
   to its operations. The consolidated financial statements of the Company are
   presented under the presumption that they will continue as a separate going
   concern.

   PRINCIPLES OF CONSOLIDATION - The consolidated financial statements include
   the accounts of the Company and its majority-owned subsidiaries. All
   significant intercompany transactions and balances have been eliminated.

   CASH EQUIVALENTS - Short-term investments with original maturities of three
   months or less are considered cash equivalents.

   DEPRECIATION AND AMORTIZATION are computed using the straight-line method
   over the estimated useful lives of the related assets which approximate 3 to
   30 years.

   INVESTMENT IN PARTNERSHIPS - The Company accounts for its investment in 50%
   or less owned partnerships under the equity method of accounting.

   INTEREST RATE SWAPS - The Company uses interest rate swap agreements to
   manage its exposure to fluctuations in interest rates. These financial
   instruments are recorded on an accrual basis. Amounts to be paid or received
   under interest rate swap agreements are recognized as an adjustment to
   interest expense in the periods in which they accrue.

   INCOME TAXES - The Company uses the liability method of accounting for
   deferred income taxes. Deferred tax liabilities and assets reflect the
   expected future tax consequences, based on enacted tax law, of temporary
   differences between the tax bases of assets and liabilities and their
   financial reporting amounts. The Company files consolidated income tax
   returns with PacifiCorp. The Company's tax is computed on a stand-alone
   basis.

   ASSET IMPAIRMENT - Effective January 1, 1996, the Company adopted Statement
   of Financial Accounting Standards ("SFAS") 121, Accounting for the
   Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of.
   This Statement requires that long-lived assets and certain identifiable
   intangibles to be held and used by an entity be reviewed for impairment
   whenever events or changes in circumstances indicate that the carrying
   amount of an asset may not be recoverable. The Company evaluated all its
   assets based upon SFAS 121 and made adjustments as disclosed in Note 12.


                                     15

<PAGE>   16
    USE OF ESTIMATES - The preparation of financial statements in conformity
    with generally accepted accounting principles requires management to make
    estimates and assumptions that affect the reported amounts of assets and
    liabilities and disclosure of contingent assets and liabilities at the date
    of the financial statements. Actual results could differ from those
    estimates.

    ONSITE Funding, a wholly-owned subsidiary of the Company, issued 9.93%
    senior secured notes, Series A, in the amounts of $3,867 and $8,483,
    pursuant to six separate note agreements dated as of August 15, 1988 and
    December 15, 1988, respectively, between ONSITE Funding and Connecticut
    General Life Insurance Company, Horace Mann Life Insurance Company, and
    CIGNA Property and Casualty Insurance Company. The notes, which are due
    December 31, 1998, June 30, 2000 and December 31, 2000, are payable in
    semi-annual installments including interest at 9.93% per annum and are
    guaranteed by Holdings.

    REVENUE BOND - Camas Power Boiler Limited Partnership ("Camas"), an
    indirectly wholly-owned subsidiary of the Company, has a loan agreement
    with Industrial Revenue Bond Public Corporation of Clark County, Washington
    consisting of $15,000 collateralized, nonrecourse debt, of which $12,640 is
    outstanding at December 31, 1996. The debt is collateralized by a Letter of
    Credit from Swiss Bank Corporation and interest in the assets of the
    project.

    Industrial Revenue Bond Public Corporation issued Series 1990 A Revenue
    Bonds for the purpose of loaning the proceeds of such bonds to Camas to be
    used to finance part or all of the acquisition, construction and equipping
    of a waste wood-fired steam boiler at the James River Corporation in Camas,
    Washington.

    Interest is payable on each February 1 and August 1, commencing August 1,
    1991 and continuing through August 1, 2007. The interest rate at December
    31, 1996 and 1995 was 7.2%.

    TERM LOAN - Camas has a term loan note with Swiss Bank Corporation
    consisting of a $20,196 collateralized note as of December 31, 1996. The
    note is collateralized by Camas' contract rights, future revenues derived
    from the ownership or operation of the project, all other personal property
    and fixtures, all monies and investments on deposit, and all other rights
    or claims of Camas. The note is without recourse to the partners.

    The term loan note is due in 60 quarterly installments through June 30,
    2007 with interest at Eurodollar rate plus .625% for five years and .75%
    thereafter. Camas has entered into an interest rate swap agreement (for the
    same amount as debt maturities), which provides a fixed interest rate of
    7.52% through September 30, 1997 and a rate of 7.645% thereafter.

    Camas is exposed to credit loss in the event of nonperformance by the
    counterparties to the interest rate swap agreement. However, Camas does not
    anticipate nonperformance by the counterparties.

    Maturities of long-term debt for years ending December 31 are as follows:

    In accordance with the loan and bond agreements, Camas has established a
    sinking fund for the repayment of the debt. The balance at December 31,
    1996 and 1995 is $1,149 and $1,157, respectively, and is shown as
    restricted cash.

    The Company capitalizes costs incurred in obtaining long-term debt. The
    costs are amortized using the straight-line method over the term of the
    associated debt.

6.   INCOME TAXES

    The Company's net deferred tax liability at December 31 was composed as
    follows:

</TABLE>                                                                  
                                                                             
    The Company's net deferred tax liability at December 31, 1996 and 1995
    resulted primarily from the effect of the excess of tax depreciation over
    financial reporting depreciation, partially offset by the effect of net
    operating loss carryforwards and investment tax credits.

    At December 31, 1996, the Company has investment tax credit carryforwards
    for tax purposes of $1,904 and net operating loss carryforwards for tax
    purposes of $6,227, which begin to expire in 2000 and 2002, respectively.

    The difference between income tax expense reported for the years ended
    December 31, 1996 and 1995 and the amount of income tax which would result
    from applying U.S. statutory rates to pre-tax income from continuing
    operations is due primarily to state income taxes.

    The total income tax expense for the year ended December 31 was as follows:

7.   SUPPLEMENTAL CASH FLOW INFORMATION

   Interest paid was $609 and $302 for the years ended December 31, 1996 and
   1995, respectively. Income taxes paid were $3,060 and $3,310 for 1996 and
   1995, respectively.

8.   RELATED-PARTY TRANSACTIONS

   Related-party transactions which have not been disclosed in other footnotes
   are described herein.

   The Company and Holdings made advances of funds to one another under an
   intercompany loan agreement. These advances are due upon demand and bear
   interest at Holdings' external borrowing rate, which was 5.49% and 5.87% at
   December 31, 1996 and 1995, respectively. The Company earned net interest
   income of $451 and $784 in 1996 and 1995, respectively. Advances to Holdings
   were $6,873 and $6,995 at December 31, 1996 and 1995, respectively, and are
   included as accounts receivable PacifiCorp Holdings, Inc. in the
   accompanying balance sheets.

   Holdings and PacifiCorp provide the Company administrative and engineering
   services on an as-needed basis. The amount charged the Company for these
   services was $798 and $226 in 1996 and 1995, respectively.

   The Company provides engineering, administrative, operational and
   maintenance services to Crockett Cogeneration Limited Partnership. The total
   charged for such services was $751 and $474 in 1996 and 1995, of which $129
   and $67 was receivable at December 31, 1996 and 1995, respectively.

9.   FAIR VALUE OF FINANCIAL INSTRUMENTS

   Fair value of financial instruments is defined as the amount at which the
   instrument could be exchanged in a current transaction between willing
   parties.

   The following methods and assumptions were used to estimate the fair value
   of each class of financial instruments:

   CASH AND CASH EQUIVALENTS, RESTRICTED CASH, RECEIVABLES, PAYABLES, AND
   ACCRUED LIABILITIES - The carrying amount approximates fair value because of
   the short maturity of those instruments.

   LONG-TERM DEBT - The fair value of the Company's long-term debt has been
   estimated by discounting projected future cash flows, using the current rate
   at which similar loans would be made to borrowers with similar credit
   ratings and for the same maturities. At December 31, 1996 and 1995, the
   estimated fair value of the Company's long-term debt was $38,549 and
   $40,613, respectively.

   INTEREST RATE SWAP AGREEMENT - The fair value of the interest rate swap (see
   Note 5) is the estimated amount that the Company would pay to settle the
   swap agreement at the reporting date, determined by obtaining quotes from
   the counterparties. At December 31, 1996 and 1995, the estimated fair value
   of the interest rate swap was $500 and $1,400, respectively.

10.  COMMITMENTS AND CONTINGENCIES

   The Company leases its office space and certain equipment and facilities
   under operating lease agreements. Rent expense under these agreements was
   $185 and $167 in 1996 and 1995, respectively.

    Long-term debt of partnerships accounted for under the equity method of
    accounting is nonrecourse to the Company and is collateralized by the
    assets of the partnerships. The Company's partnership interest in
    Curtis/Palmer Hydroelectric Company totaling approximately $6,647 is
    pledged as additional collateral for the long-term debt of that
    partnership.

    The Company is committed to make capital contributions to Penobscot Energy
    Recovery Company to supplement their debt reserve fund up to $1,429 if such
    payments are not met through operations.

    The Company was committed to make capital contributions to Kingston
    Cogeneration at conversion of the project's term loan to permanent
    financing. The Company made an equity contribution of $5,114 to Kingston
    Cogeneration in September 1997.

    The Company has outstanding at December 31, 1996 a commitment of up to
    $5,000 to make investments in the Energy Investors Fund III. Investment
    commitments of $1,401 remain outstanding as of September 1997.

    In connection with various performance obligations, Holdings, on behalf of
    the following investments, has provided at December 31, 1996 irrevocable
    letters of credit to secure performance:

    The Company and its subsidiaries are parties to various legal claims,
    actions, and complaints, certain of which involve material amounts.
    Although the Company is unable to predict with certainty whether or not it
    will ultimately be successful in these legal proceedings, or, if not, what
    the impact might be, management presently believes that disposition of
    these matters will not have a materially adverse effect on the Company's
    consolidated financial statements.

11.  RETIREMENT PLAN

    Substantially all of the Company's salaried employees are covered by
    noncontributory pension plans (the plans) which are sponsored by
    PacifiCorp. The Company's portion of pension costs was $92 and $86 in 1996
    and 1995, respectively. Because actuarial information regarding the status
    of the plans is computed for the plans in total, the Company does not
    separately determine its portion of the actuarial present value of
    accumulated plan benefits or net assets available for benefits. The
    PacifiCorp retirement plan is currently underfunded.

12.  IMPAIRMENT LOSSES

   In late 1996, Carolina Energy Limited Partnership ("Carolina") failed to
   meet certain operational and financial covenants contained within the
   provisions of their loan agreements with certain banks. During the same
   period, the Company's investment in VEDCO Energy, whose subsidiary was a
   general partner in Carolina, became impaired. Subsequent attempts to
   renegotiate Carolina's debt failed and the Company's $3,176 letter of credit
   which secured the debt was called by the banks in June 1997. The total
   impairment loss incurred and recorded in 1996 by the Company related to its
   investments in VEDCO Energy of $2,120 and Carolina of $6,879, including the
   letter of credit.

13.  INVESTMENT IN BAKUN AC HYDRO POWER PROJECT

   In January 1997, the Company acquired a one-third interest in Luzon Hydro
   Corporation, a Philippine corporation ("LHC"), for $2,923. LHC was formed to
   construct and operate a proposed 70MW Bakun AC Hydro Power Project in the
   Philippines. In connection with financing obtained in June 1997, Holdings
   has provided letters of credit totaling $31,880 in support of a loan
   facility and a performance bond. Additionally, Holdings has provided a
   guarantee in the amount of $14,900 to support cost overruns and debt service
   reserves.

PACIFIC GENERATION COMPANY
NOTES TO FINANCIAL STATEMENTS
FOR THE PERIOD ENDED SEPTEMBER 30, 1997
(IN THOUSANDS OF DOLLARS)
================================================================================

   NOTE 1: - BASIS OF COMPANY PRESENTATION
   Pacific Generation Company (the Company), an indirect wholly owned 
   subsidiary of PacifiCorp is engaged in the ownership and operation of 11
   energy projects located in the United States and Canada.  One of the
   projects is located in Canada and the other ten are broadly distributed
   throughout the United States.  The fuels used by the projects include
   natural gas, coal, hydro, waste wood, refused derived fuel and wind.  One of
   the projects sells only steam, while the other ten have power sales
   agreements with a total of seven different utilities.

   When reading the financial information contained in these interim financial
   statements, reference should be made to the audited financial statements 
   and notes contained in the Company's financial statements for the years 
   ended 1996 and 1995.

   Reference is made to the Summary of Significant Accounting Policies
   contained in the notes to the 1996 and 1995 financial statements.  These
   policies guided the preparation and presentation of these interim financial
   statements.

   The preparation of financial statements in conformity with generally
   accepted accounting principles required management to make estimates and
   assumptions that affect the reported amounts of assets and liabilities, the
   disclosure of contingent assets and liabilities at the date of the financial
   statements, and the reported amounts of revenues and expense during the
   reporting period.  Actual results could differ from those estimates.  On an
   on going basis, management reviews its estimates based on currently
   available information.  Changes in facts and circumstances may result in
   revised estimates.  In the opinion of management, the combined financial
   statements include all material adjustment necessary to present fairly the
   Company's financial position, results of operations, and cash flows.  Such
   adjustments are of normal recurring nature.  The results for this interim
   period are not necessarily indicative of results for the entire year or any
   interim period.

   NOTE 2: - STOCK SALE TO NRG ENERGY, INC.

   On November 4, 1997, NRG Energy, Inc., purchased all the equity of Pacific 
   Generation Company together with other equity interest and assets related to
   Pacific Generation Company from PacifiCorp for an aggregate price of 
   $148.6 million.  Certain subsidiaries not significant to Pacific Generation 
   Company were not purchased.
        
   NOTE 3: - IMPAIRMENT LOSSES

   In late 1996, Carolina Energy Limited Partnership ("Carolina") failed to
   meet certain operational and financial covenants contained within the
   provisions of their loan agreements with certain banks.  During the same
   period, the Company's investment in VEDCO Energy, whose subsidiary was a
   general partner in Carolina, became impaired.  Subsequent attempts to
   renegotiate Carolina's debt failed and the Company's $3,176 letter of credit
   that secured the debt was called by the banks in June 1997.  The total
   impairment loss incurred and recorded in 1996 by the Company related to its
   investments in VEDCO Energy of $2,120 and Carolina of $6,879, including the
   letter of credit.  Carolina and VEDCO were not purchased by NRG Energy, Inc.

   NOTE 4: - WINDPOWER PARTNERS (CONSISTING OF WINDPOWER 87 & WINDPOWER 88)

   In May 1997, the operator/general partner of WindPower Partners declared
   bankruptcy and the general partnership was taken over by Pacific Generation
   Company and Mountain Energy California.  In June 1997, Pacific Generation
   Company and Mountain Energy California purchased WindPower Partners
   subordinated debt of $26,600 at a discount for $12,900.

                        NOTES TO PRO FORMA BALANCE SHEET
                               DECEMBER 31, 1996



(1)  The pro forma balance sheet at December 31, 1996 reflects the pro forma
     adjustments required to present the acquisition of Pacific Generation
     Company, as if the acquisition took place on December 31, 1996.  The
     Company has elected to step up the asset basis of its acquired
     subsidiaries of Pacific Generation Company.  However, at the current
     time, the appraisals and the Company's review of these appraisals have
     not been completed so the pro forma assets shown are based on estimated
     values and best information at this time.  Therefore, the Company cannot
     state with certainty the amount of acquisition costs that will be
     capitalized or the value of intangible assets, including goodwill
     associated with the acquisition.

(2)  Reflects the estimated step up in value for Camas project, a wholly owned
     asset of Pacific Generation Company.

(3)  Reflects the estimated change in value for Pacific Generation Company's 
     share in equity investments.  See Item 2 for description of projects.

(4)  The Company, as part of the purchase, acquired notes receivable related 
     to Wind Power 87 and Wind Power 88.  These notes were purchased by Pacific
     Generation Company in June 1997.

(5)  Reflects the estimated amount of current of intangible assets resulting 
     from the transaction, including amounts related to operating agreements and
     goodwill.

(6)  Reflects approximately $3.7 million of investments of Pacific Generation
     Company not purchased.  This includes primarily PacGen Holdings and Pacific
     Generation Company international subsidiaries.

(7)  NRG did not assume, as part of the purchase, the current or deferred tax
     liabilities and intercompany payables of Pacific Generation Company.  
     These are eliminated and result in a reduction in intangible assets.

(8)  Reflects the short term financing used to acquire the Pacific Generation
     Company investment.

(9)  Reflects the estimated acquisition costs to acquire Pacific Generation
     Company which will be capitalized as part of the acquisition.

(10) Reflects the increase in minority interest due to a step up in project
     valuations.

(11) Eliminating entry to remove Pacific Generation Company shareholder equity.

 (1)  The pro forma income statement for the year 1996 reflects the pro 
      forma income statement adjustments required to present the estimated 
      combined results of the Company and Pacific Generation Company as if
      the acquisition of Pacific Generation Company took place on 
      January 1, 1996.  
                                
(2)   Represents the equity (expenses) of those Pacific Generation Company 
      affiliates not purchased but included in the audited 
      financial 
      statements.                            

(3)   Reflects the ownership percentage change the Company will realize in the 
      Crockett Cogeneration project (see Item 2 discussion of Crockett
      Cogeneration project) offset by increased depreciation and amortization  
      costs for stepped up project valuations resulting from acquisition 
      appraisals.  The stepped up valuations are being amortized over the 
      remaining life of each project's contracted sales agreements for 
      electricity or steam. 

(4)   Reflects the increased depreciation due to stepped up value of Camas 
      project, a wholly owned asset, and amortization of intangibles over      
      30 years.                              

(5)   Represents accrued interest on $148.63 million principal amount for 
      twelve months at a rate of 7.24% per annum. 
                                
(6)   Reflects the minority interest related to the stepped up project 
      valuation.

(7)   Net tax benefit derived from pretax loss.

                 NRG ENERGY, INC. - PACIFIC GENERATION COMPANY
                        NOTES TO PRO FORMA BALANCE SHEET
                               SEPTEMBER 30, 1997


(1)  The pro forma balance sheet at September 30, 1997 reflects the pro forma
     adjustments required to present the acquisition of Pacific Generation
     Company, as if the acquisition took place on September 30, 1997.  The
     Company has elected to step up the asset basis of its acquired
     subsidiaries of Pacific Generation Company.  However, at the current time, 
     the appraisals and the Company's review of these appraisals have not been
     completed so the pro forma assets shown are based on estimated values and
     best information at this time.  Therefore, the Company cannot state with
     certainty the amount of acquisition costs that will be capitalized or the
     value of intangible assets, including goodwill associated with the
     acquisition.

(2)  Reflects the estimated step up in value for Camas project, a wholly owned
     asset of Pacific Generation Company.

(3)  Reflects the estimated change in value for Pacific Generation Company's 
     share in equity investments.  See Item 2 for a description of projects.

(4)  Reflects the estimated amount of intangible assets resulting from the
     transaction, including amounts related to operating agreements and
     goodwill.

(5)  The Company did not assume, as part of the purchase, the current or 
     deferred tax liabilities and intercompany payables of Pacific Generation 
     Comppany.  These are eliminated and result in a reduction in intangible 
     assets.

(6)  Reflects the short term financing used to acquire the Pacific Generation
     Company investment.

(7)  Reflects the estimated acquisition costs to acquire Pacific Generation
     Company which will be capitalized as part of the acquistion.

(8)  Reflects the increase in minority interest due to a step up in project
     valuations.

(9)  Eliminating entry to remove Pacific Generation Company shareholder equity.

equal to the change in stockholder's equity in the Company (computed in
accordance with GAAP) for the period from July 31, 1997 through the Closing Date
(taking into account the contribution by Seller of the balance of intercompany

Purchase Price Adjustment, the stockholder's equity of the Company as of July
31, 1997 shall be deemed to be as set forth on the proforma financial statement
set forth on attached Exhibit D, which is prepared based upon the July 31, 1997
balance sheet of the Company as adjusted to reflect the transfer of the Overseas
Operations to Seller or an Affiliate of Seller.

                           (iii) At least three days prior to the Closing,
Seller shall deliver to Buyer a statement setting forth the projected
stockholder's equity in the Company as of the Closing Date, as applicable, and
the estimated Purchase Price Adjustment. At Closing, the Purchase Price shall be
adjusted by the full amount of the estimated Purchase Price Adjustment.
Following Closing, the Parties `shall compute the Purchase Price Adjustment.
Within five days after Seller and Buyer have agreed upon the Purchase Price
Adjustment (or, if the Parties are unable to agree, within five days after the
decision of the Auditors), Buyer shall pay to Seller, or Seller pay to Buyer, as
the case may be, the difference between the 






                                       6
<PAGE>   12

actual amount of the final Purchase Price Adjustment and the amount of the
estimated Purchase Price Adjustment utilized for computing the payment by Buyer
at Closing, plus interest thereon at the Applicable Rate. If the Parties have
not, within thirty days after the Closing, agreed upon the final Purchase Price
Adjustment, the final Purchase Price Adjustment shall be conclusively determined
jointly by Price Waterhouse LLP and Deloitte & Touche, LLP (the "Auditors")
whose decision shall be final and unappealable, the cost of which shall be
shared equally by Buyer and Seller. The Auditors shall provide a draft of its
Purchase Price Adjustment computation to both Parties, who shall have ten days
from receipt of such draft to advise the Auditors of any concerns or
disagreements regarding the draft Purchase Price Adjustment calculation.

(other than conditions with respect to actions the respective Parties will take
at the Closing itself) are satisfied or waived or such other date as the Buyer
and the Seller may mutually determine (the "Closing Date").

will deliver to the Buyer the various certificates, instruments, and documents
referred to in Section 7(a) below, (ii) the Buyer will deliver to the Sellers

         reorganization, moratorium, or similar laws affecting creditor's rights

            4(g) Financial Statements. Attached hereto as Exhibit A are the
following financial statements (collectively the "Financial Statements"): (i)

consolidated balance sheets and statements of income, changes in stockholders'
equity, and cash flow as of and for the years ended December 31, 1995 and
December 31, 1996 for the Company and its consolidated Subsidiaries (the "Most
Recent Financial Statements"), (iii) unaudited consolidated balance sheets and
statements of income, changes in stockholder's equity, and cashflow and as of
and for the seven months ended July 31, 1997 (the "Most Recent Period End") for
the Company and its consolidated Subsidiaries. The Financial Statements
(including the notes thereto) have been prepared in accordance with GAAP applied
on a consistent basis throughout the periods covered thereby and present fairly
the financial condition of the Company and its consolidated Subsidiaries as of
such dates and the results of operations of the Company and its consolidated
Subsidiaries for such periods, and are consistent with the books and records of
the Company and its consolidated Subsidiaries; provided, however, that the Most
Recent Period End Financial Statements are subject to normal year-end
adjustments and lack footnotes and other presentation items. To Seller's
Knowledge, the Company, the Subsidiaries and the Operated Entities do not have
any liabilities that are required to be reflected in a balance sheet which is
prepared in accordance with GAAP, which individually or in the aggregate, would
have a Material Adverse Effect, except for (i) liabilities reflected or reserved
against in the Most Recent Period End Financial Statements; (ii) liabilities
that have arisen in the ordinary course after July 31, 1997; or (iii)
liabilities described in the Disclosure Schedule.

any Operated Entity which would individually or in the aggregate have a material
adverse effect on such entity except for the transfer of the Overseas
Operations, and the stock of Pacific Kinston Energy, Inc., as contemplated by
Sections 5(i) and 5(j), and the transfer of the Headquarters Lease and
Headquarters Equipment as contemplated by Section 5(k).

            4(i) Legal Compliance. Each of the Company, its Material
Subsidiaries, and Operated Entities is in substantial compliance (and has been
in substantial compliance excepting noncompliance which has been corrected) with
all applicable laws (including rules, regulations, codes, plans, injunctions,
judgments, orders, decrees, rulings, and charges thereunder) of federal, state,
local, and foreign governments (and all agencies thereof), except where the
failure to comply would not have a material adverse effect on such entity. Each
of the Company, its Material Subsidiaries and Operated Entities has all permits,
licenses, 





                                       12

certificates of authority, orders and approvals of, and has made all filings,
applications, and regulations with federal, state, local or foreign government
or regulatory bodies that are currently required in order to permit it to carry
on its business as presently conducted, the absence of which individually or in
the aggregate would reasonably be expected to have a material adverse effect on

                  6(c) Transition. Seller, PacifiCorp and their Affiliates will
not take any action that is designed or intended to have the effect of
discouraging any lessor, licensor, customer, supplier, or other business
associate of any of the Company, its Subsidiaries and the Project Entities
(other than Seller and its Affiliates) from maintaining the same business
relationships with the Company, its Subsidiaries and the Project Entities after
the Closing as it maintained with the Company, its Subsidiaries and the Project
Entities prior to the Closing.

                  6(d) Benefit and Employee Matters. This Section 6(d) contains
the covenants and agreements of the Parties with respect to (a) the status of
employment of the employees of the Company, the Subsidiaries and the Operated
Entities ("Employees") upon the sale of the Company to Buyer, and (b) employee
benefit plans. Nothing herein expressed or implied is intended to confer upon
any Employee or former Employee of Seller any right or remedy, including,
without limitation, any right as a third party beneficiary.

                       (i) Employee Status. Buyer shall, at least ten days prior
         to the Closing, deliver to Seller a list of the employees selected from
         the list on Schedule 6(d) which Buyer does not wish to employ after the
         Closing (the "Employee List"). Seller shall cause all employees listed
         on the Employee List, at or prior to the Closing, to be transferred to
         the employment of Seller or an Affiliate of the Seller. Buyer shall
         deem, and shall cause the Company to deem for all Employees the period
         of employment with Company and the Subsidiaries and Operated Entities
         (and with predecessor employers with respect to which the Company, the
         Subsidiaries and Operated Entities have granted service credit) to be
         employment with Buyer for benefit plan eligibility and vesting
         purposes, but not (except as otherwise provided in Section 6(d)(iv))
         for benefit accrual purposes, under all of Buyer's and Company's
         Employee Benefit Plans, programs, or arrangements to the extent service
         with Buyer or Company is recognized under any such plan, program or
         arrangement. Buyer's covenant to recognize prior service for
         eligibility and vesting purposes shall not obligate Buyer or Company to
         include all classes of Employees in each of Buyer's or Company's
         Employee Benefit Plans, programs, or arrangements.

                       Buyer agrees that if any of the Employees of the Company
         listed on Part II of Schedule 6(d) and not listed on the Employee List
         is (x) terminated from employment for reasons other than cause within
         12 months after the Closing by the Company, its Subsidiaries, or
         Operated Entities, or (y) experiences within 12 months after the
         Closing a "material alteration in assignment or compensation" or a
         "material change in geographic location", as such terms are defined in
         the "Safety Net

         Guidelines for Pacific Generation Company" adopted effective July 1,
         1997 (the "Regular Plan"), Buyer shall, or shall cause the Company to,

         Plan. Buyer agrees that if any of the employees of the Company listed
         on Part I of Schedule 6(d) and not listed on the Employee List is
         terminated from employment within 18 months after Closing by the
         Company for reasons other than cause, or experiences within 18 months
         after Closing a "Material Alteration in Position", as defined in the
         "Pacific Generation Company Key Executive Severance Benefits Plan"
         adopted effective July 1, 1997 (the "Key Employee Plan"), Buyer shall,
         or shall cause Company to, give notices and provide severance benefits
         as provided in the Key Employee Plan. Seller agrees to indemnify Buyer
         and Company for any liability and expenses, including severance
         benefits and attorney fees, arising from claims by or on behalf of
         employees listed on the Employee List under the Regular Plan or the Key
         Employee Plan.

                       (ii) Plan Sponsorship. Except as provided in Section
         6(d)(i), (iii)(C), (iii)(D), and (iv), Buyer shall not, and shall not
         cause Company to, adopt or be directly or indirectly responsible for
         administering, funding or maintaining after the Closing Date any
         Employee Benefit Plan maintained prior to the Closing Date by Company,

         which failure occurred as a result of the actions required by this

         the medical expense reimbursement arrangement in its cafeteria plan.

                        (iv) Buyer Continuation of Company Benefits. Buyer
         and Seller acknowledge that, as of the Closing Date, Esoco Crockett,
         Inc. will no longer be able to comply with those provisions of the
         Collective Bargaining Agreement between Esoco Crockett, Inc. and
         International Union of Operating Engineers, Stationary Local No. 39,
         AFL-CIO (the "Union Contract") which requires that Esoco Crockett, Inc.
         continue the participation of certain employees in Employee Benefit
         Plans maintained by Seller or an Affiliate of Seller. Buyer shall use
         its best efforts to negotiate with said union to substitute Buyer's
         Employee Benefit Plans for the Employee Benefit Plans referenced in the
         Union Contract. If such negotiations result in an agreement that
         employees of Esoco Crockett, Inc. who are covered by the Union Contract
         ("Union Employees") shall be covered by a defined benefit plan with
         benefits substantially similar to the PacifiCorp Retirement Plan, then,
         and only in that event, shall the following provisions of this Section
         6(d)(iv) apply.

                             Buyer shall assumes as of the date of the transfer
         of assets pursuant to this Section 6(d)(iv), the liabilities and
         obligations of the PacifCorp Retirement Plan for all Union Employees.
         Buyer shall establish, effective as of the Closing Date, a
         tax-qualified "defined benefit plan", as defined in Section 3(35) of
         ERISA ("Buyer's Pension Plan"), which shall discharge the obligations
         of Buyer as set forth in this Section 6(d)(iv). As soon as practicable
         after the Closing Date, Seller shall cause a transfer from the
         PacifiCorp Retirement Plan of the liabilities and obligations of the
         Union Employees and of the assets described below to the Buyer's
         Pension Plan.

                             The assets to be transferred from the PacifiCorp
         Retirement Plan with respect to the Union Employees shall be an amount
         equal to the greater of (i) the total value of the assets (including
         accrued but unpaid contributions) as of the Closing Date of the
         PacifiCorp Retirement Plan multiplied by a fraction the denominator of
         which is the "projected benefit obligation," as defined within
         Financial Accounting Standards No. 87, for the pension benefits of all
         participants in the PacifiCorp Retirement Plan and the numerator of
         which is the "projected benefit obligation" of the pension benefits of
         the Union Employees in the PacifiCorp Retirement Plan, as of the
         Closing Date, and (ii) the "projected benefit obligation" for the
         pension benefits of the Union Employees under the PacifiCorp Retirement
         Plan as of the Closing Date, with adjustments described below for
         investment earnings and benefit payments between the Closing Date and
         the actual date of such transfer of assets. The above "projected
         benefit obligation" shall include an amount reflecting, on an actuarial
         basis, benefits attributable to the effect of an assumption for future
         pay increases after the Closing Date. Seller's actuary shall calculate
         the above "projected benefit obligation" by applying the funding
         assumptions described in the attachment to the PacifiCorp Retirement
         Plan's most recently filed IRS Form 5500, Schedule B and other relevant
         actuarial assumptions, methods and methodologies, described in such
         attachment and/or used in preparing calculations shown on such Form
         5500, except that the annual interest rate assumption to be used to
         calculate the 



                                       30
<PAGE>   36

         above "projected benefit obligation" shall be the immediate annuity
         rate prescribed by the Pension Benefit Guaranty Corporation for the
         month in which the transfer of assets occurs.

                           The assets transferred pursuant to this Section
         6(d)(iv) shall be calculated by Seller's actuary, and shall be subject
         to review by Buyer's actuary for the purpose of confirming that the
         calculation was made in accordance with this Section 6(d)(iv). In the
         event that actuaries of the Parties do not agree, the determination of
         an independent actuary, as selected and agreed upon by Buyer and
         Seller, shall be final. The cost and expense of such independent
         actuary shall be equally shared by the Parties. The amount of assets as
         so determined shall be adjusted for investment earnings for the period
         between the Closing Date and the actual date of transfer at a rate
         equal to the rate of interest on 90-day United States Treasury bills as
         of the Closing Date as published in The Wall Street Journal, and
         reduced by the amount of any benefit payments to Union Employees. In
         connection with the implementation of this Section 6(d)(iv), Buyer and
         Seller shall cooperate in the preparation of all documentation required
         to be filed with the Internal Revenue Service, the Department of Labor
         and any other applicable governmental agency.

                  6(e) Access to Information. After the Closing, Buyer shall
afford to Seller and PacifiCorp, and their respective representatives and
advisors, such access during normal business hours with reasonable notice, to
the books, records and personnel of the Company, its Subsidiaries and Operated
Entities and to such other information, and shall furnish such cooperation
relating to the Company, its Subsidiaries, Project Entities and Operated
Entities, as Seller shall reasonably request for financial reporting and
accounting matters, the preparation and filing of any tax returns, the defense
of tax claims, and related purposes. Buyer shall cause Company to preserve all
tax and accounting records of Company, its Subsidiaries and Operated Entities
for a period of seven (7) years following the Closing. In addition, Seller shall
afford Buyer, its respective representatives and advisors, similar access to any
books, records, files retained by Seller relating to the business of the
Company, its Subsidiaries, Project Entities, and Operating Entities.

                  6(f) Transition Services. If requested by Buyer, and subject
to negotiation of mutually acceptable conditions, Seller will provide, at its
actual cost, administrative services reasonably requested by Buyer with respect
to the Company for a period not to exceed 90 days after the Closing.

                  6(g) Maintenance of Minimum Equity. For a period of five years
following the Closing Date, or if earlier, the date that Seller has made
aggregate indemnity payments hereunder of at least $66,650,000, Seller or its
successor shall maintain minimum consolidated stockholder's equity, as reflected
on its regularly prepared balance sheets, of $100,000,000. Seller covenants and
agrees that Seller will notify Buyer in advance of any transaction which would
cause a breach of this provision.

                  6(h) Philippine Option. Seller grants Buyer an option (the
"Option") to purchase the outstanding capital stock held by Seller or its
Affiliates in the entities listed on Schedule 6(h) attached hereto (the
"Philippines Subsidiaries"). The Option is exercisable only by Buyer notifying
Seller in writing, prior to thirty days after the date of this Agreement, that
Seller has exercised the Option. Buyer will endeavor to decide in advance of the
expiration of the 30 day period, whether to exercise the Option, and to notify
Seller of its decision as soon as practicable. If the Option is not so exercised
within such period, the Option shall expire, and Buyer shall have no further
right or option to acquire the Philippine Subsidiaries. In the event that Buyer
so exercises the Option, (i) Seller will sell to Buyer, or cause its Affiliates
to sell to Buyer, all of the issued and outstanding capital stock of the
Philippine Subsidiaries held by the Seller or its Affiliate; and (ii) the
Parties will execute a Stock Purchase Agreement substantially in the form of
this Agreement, with the following modifications:

Affiliates to the Philippine Subsidiaries between the date of this Agreement and
Closing, and, without double-counting, all expenditures of the Philippine
Subsidiaries between the date of this Agreement and Closing and adjusted
downward by all distributions made by the Philippine Subsidiaries to Seller and
its Affiliates between the date of this Agreement and Closing.

                       (iv) Section 2(c) shall not apply.

                       (v) Section 3(a)(v) shall be revised to reflect the sale
of the shares of each Philippine Subsidiary.

                       (vi) Section 4(b) shall be revised to reflect the
capitalization of each Philippine Subsidiary.

                       (vii) Sections 4(f), 4(g), 4(h), 4(j), 4(k), 4(n), 4(r),
4(s), 4(t) and 4(y) shall not apply.

                       (viii) The Philippine Subsidiaries shall be treated as
Project Entities for purposes of Sections 4, 5(b), 5(c) and 5(d).

                       (ix) The Aggregate Deductible under Section 1 shall be

Agreement shall be as set forth on Annex IV attached hereto, with such
modifications as are reasonably necessary or appropriate to make such Disclosure
Schedule accurate and complete.

                       (xi) Any other modifications that Buyer and Seller
jointly reasonably deem necessary or appropriate in order to make the Stock
Purchase Agreement applicable to the transaction contemplated by the Option.

The Parties shall include the possible sale of the Philippine Subsidiaries in
their respective filings with respect to this Agreement under the
Hart-Scott-Rodino Act.

In the event that Buyer exercises the Option, and Seller is precluded from
consummating the transaction contemplated by the Option due to Seller's
inability to obtain any third party consents, approvals, or waivers, or the
exercise of any right of refusal or similar right, Seller shall notify Buyer,
and shall reimburse Buyer for costs incurred by Buyer after the date hereof and
prior to such notice which are directly related to the due diligence on the
Philippine Subsidiaries and the underlying projects of the Philippine
Subsidiaries, and Seller shall have no further obligation under this Section
6(h).

In the event that Seller exercises the Option, this Agreement shall be
automatically amended (i) to increase the aggregate ceiling under Section 8(b)
by $4,250,000; and (ii) to increase the Aggregate Deductible specified in
Section 1 by the sum of $170,000, and claims made under the indemnity provisions
of such Stock Purchase Agreement and this Agreement shall be considered in
determining the applicability of the aggregate ceiling and aggregate deductible
under each Agreement.

         8.       Remedies for Breaches of This Agreement.

                  8(a) Survival of Representations and Warranties. All of the
representations and warranties of the Seller contained in Section 3 above shall
survive the Closing hereunder indefinitely. The representations and warranties
of the Buyer contained in Section 3 above shall survive the Closing hereunder
indefinitely. All of the representations and warranties of Seller contained in
Section 4 shall survive the Closing hereunder, and continue in full force and
effect for a period of two (2) years thereafter, except for the representations
and warranties contained in Section 4(j), which shall continue until the
expiration of the applicable statutes of limitation to which the liabilities
relate, and the representations and warranties in Section 4(o), which shall
survive the Closing hereunder and continue in full force and effect for a period
of five (5) years thereafter.

                  8(b) Indemnification Provisions for Benefit of the Buyer.

                       (i) In the event the Seller breaches any of its
         representations, warranties, and covenants contained herein (other than
         the covenants in Section 2(a) above and the representations and
         warranties in Section 3(a) above), and, if there is an applicable
         survival period pursuant to Section 8(a) above, provided that the Buyer
         makes a written claim for indemnification against Seller pursuant to
         Section 11(g) below within such survival period, then the Seller agrees
         to indemnify the Buyer from and against any Adverse Consequences the
         Buyer shall suffer resulting from, arising out of, or caused by such
         breach; provided, however, that the Seller shall not have any
         obligation to indemnify the Buyer from and against any Adverse
         Consequences caused by the breach of any representation or warranty of
         the Seller contained in Section 4 above (A) until the Buyer has
         suffered Adverse Consequences by reason of all such breaches in excess
         of the Aggregate Deductible, or thereafter (B) to the extent the
         Adverse Consequences the Buyer has suffered exceeds a $66,650,000
         aggregate ceiling (after which point the Seller will have no obligation
         to indemnify the Buyer from and against further such Adverse
         Consequences).

                       (ii) In the event the Seller breaches any of its
         covenants in Section 2(a) above or Article 9 below or any of its
         representations and warranties in Section 3(a) above, and, if there is
         an applicable survival period pursuant to Section 8(a) above, provided
         that the Buyer makes a written claim for indemnification against the
         Seller pursuant to Section 11(g) below within such survival period,
         then the Seller agrees to indemnify the Buyer from and against the
         entirety of any Adverse Consequences the Buyer shall suffer any Adverse
         Consequences the Buyer shall suffer resulting from, arising out of, or
         caused by such breach.

                       (iii) Seller agrees to indemnify Buyer from and against
         any Adverse Consequences the Buyer shall suffer resulting from, or
         arising out of, any Discontinued Operation. As used herein, a
         Discontinued Operation is: (a) a corporation, partnership, or limited
         liability company which was at one time owned, 



                                       36
<PAGE>   42

         directly or indirectly, by Company, but is not owned, directly or
         indirectly, by the Company on the date of this Agreement, or which was
         liquidated or has filed for dissolution prior to the date of this
         Agreement; (b) a property or asset which was owned, directly or
         indirectly, by Company, but is not owned, directly or indirectly, by
         the Company on the date of this Agreement; (c) any project development
         activity of the Company or its Subsidiaries which was terminated prior
         to the date of this Agreement; or (d) the Overseas Operations, the
         Company's beneficial ownership of the stock of Pacific Kinston Energy,
         Inc. or the Company's beneficial ownership in Carolina Energy Limited
         Partnership. Notwithstanding the foregoing, no indemnity shall be
         provided under this paragraph with respect to: (1) properties, assets,
         projects, or entities as to which Seller's indirect ownership was
         through the ownership of an interest in the Energy Investors Fund, LP
         or Project Finance Fund Ill, LP; and (2) if the Option is exercised,
         the Philippine Subsidiaries, and the assets and operations of the
         Philippine Subsidiaries.

                           (iv) Seller agrees to indemnify Buyer from and
         against any Adverse Consequences the Buyer, the Company, or any
         Subsidiary shall suffer resulting from or arising out of any Company,
         Subsidiary, or Operated Entity violation of any federal, state or local
         law or regulation (of any type or kind) governing employment, labor
         relations, wages, benefits, or discrimination in employment to the
         extent asserted by (i) those employees on the Employee List, or (ii)
         those employees of the Company, any Subsidiary or Operated Entity whose
         employment was terminated (either voluntarily or involuntarily) prior
         to the Closing Date.

                  8(c) Indemnification Provisions for Benefit of the Seller. In
the event the Buyer breaches any of its representations, warranties, and-
covenants contained herein, and, if there is an applicable survival period
pursuant to Section 8(a) above, provided that the Seller makes a written claim
for indemnification against the Buyer pursuant to Section 11(g) below within
such survival period, then the Buyer agrees to indemnify the Seller from and
against the entirety of any Adverse Consequences the Seller shall suffer
resulting from, arising out of, or caused by such breach.

                  8(d) Matters Involving Third Parties.

                       (i) If any third party shall notify any Party (the
         "Indemnified Party") with respect to any matter (a "Third Party Claim")
         which may give rise to a claim for indemnification against any other
         Party (the "Indemnifying Party") under this Section 8, then the
         Indemnified Party shall promptly (and in any event within five business
         days after receiving notice of the Third Party Claim) notify each
         Indemnifying Party thereof in writing. The failure to give such notice
         on a timely basis shall not affect the indemnification provided herein
         except to the extent the Indemnifying Party has actually been
         prejudiced as a result of such failure.


                                       37

<PAGE>   43

                       (ii) Any Indemnifying Party will have the right to assume
         and thereafter conduct the defense of the Third Party Claim with
         counsel of its choice reasonably satisfactory to the Indemnified Party;
         provided, however, that the Indemnifying Party will not consent to the
         entry of any judgment or enter into any settlement with respect to the
         Third Party Claim without the prior written consent of the Indemnified
         Party (not to be withheld unreasonably) unless the judgment or proposed
         settlement involves only the payment of money damages which are covered
         in full by the indemnity and does not impose an injunction or other
         equitable relief upon the Indemnified Party; provided further, however,
         with respect to claims for indemnity under Section 8(b)(i) that during
         the period in which the cumulative amount of the Adverse Consequences
         for which indemnity is being sought is less than the Aggregate
         Deductible, the Indemnified Party will have the right to assume the
         defense of a Third Party Claim with counsel of its choice reasonably
         satisfactory to the Indemnifying Party; provided, however, that the
         Indemnified Party will not consent to the entry of any judgment or
         enter into any settlement with respect to the Third Party Claim without
         the prior written consent of the Indemnifying Party (not to be
         unreasonably withheld).

                       (iii) Unless and until an Indemnifying Party assumes the
         defense of the Third Party Claim as provided in Section 8(d)(ii) above,
         however, the Indemnified Party may defend against the Third Party Claim
         in any manner it reasonably may deem appropriate.

                       (iv) In no event will the Indemnified Party consent to
         the entry of any judgment or enter into any settlement with respect to
         the Third Party Claim without the prior written consent of the
         Indemnifying Parties which consent shall not be withheld unreasonably.

                  8(e) Determination of Adverse Consequences. The Parties shall
make appropriate adjustments for tax benefits and insurance coverage and take
into account the time cost of money (using the Applicable Rate as the discount
rate) in determining Adverse Consequences for purposes of this Section 8. All
indemnification payments under this Section 8 shall be deemed adjustments to the
Purchase Price.

                  8(f) Certain Environmental Matters. Buyer (for itself and its
successors and assigns) acknowledges and agrees that Seller is not and never has
been an `owner or operator' (as that term is defined and used in any
Environmental Law) of any of the properties or facilities of the Company or the
Subsidiaries or the Projects; and Buyer (for itself and its successors and
assigns) releases Seller (and Seller's directors, officers, employees, and
affiliates) from any claims that Buyer (or its successors or assigns) might
otherwise assert on the grounds that Seller is or has been such owner or
operator, provided that nothing herein shall release Seller from its indemnity
obligations with respect to representations and warranties set forth in Section
4 of this Agreement.




                                       38
<PAGE>   44

                  8(g) Tax Indemnification. Notwithstanding any other provision
of this Agreement to the contrary, Seller shall indemnify Buyer and its
Affiliates (including the Company and its Subsidiaries) from and against
liability for Taxes (including any liabilities or obligations pursuant to any of
the tax indemnifications, cross indemnity agreements and/or tax allocation
policies described in Section 4(j) of the Disclosure Schedule) of the Company,
its Subsidiaries and/or Operated Entities of which the Company or a Subsidiary
is tax matters partner for all taxable periods ending on or before the Closing
Date and the portion up to and including the Closing Date of any taxable period
that includes but does not end on the Closing Date, including any liability for
Taxes imposed upon the Company and/or its Subsidiaries pursuant to Treasury
Regulations Section 1.1502-6 (or any comparable provision of applicable state,
local or foreign law) as a result of being a member of the Affiliated Group the
common parent of which is PacifiCorp, or any combined or unitary group including
PacifiCorp, to the extent such Taxes are not reflected in the balance sheets of
the Company, its Subsidiaries or Operated Entities of which the Company or a
Subsidiary is tax matters partner which are utilized to compute the Purchase
Price adjustment under Section 2(c). In the case of a taxable period including,
but not ending on, the Closing Date, the Taxes for the period up to and
including the Closing Date shall be computed as if such taxable period ended on
and including the Closing Date.

               9. Tax Matters.

                  9(a) Section 338(h)(10) Election. Seller will join, and will
cause its eligible Subsidiaries and the Affiliated Group the common parent of
which is PacifiCorp to join, with Buyer in making an election pursuant to Code
Section 338(h)(10) and any corresponding elections pursuant to state, local and
foreign law (collectively a "Section 338(h)(l0) Election") with respect to
purchase and sale of the stock of the Company hereunder, and with respect to its
eligible Subsidiaries, will take all actions necessary and appropriate to effect
and preserve a timely Section 338(h)(10) Election. Seller will pay any Tax
(including for this purpose federal, state, local and foreign income tax)
attributable to the making of the Section 338(h)(10) Election and will indemnify
Buyer, the Company and its subsidiaries from and against any failure to pay such
Tax. The Purchase Price and the liabilities of the Company and its Subsidiaries
(plus other relevant items) will be allocated among the assets of the Company
and its Subsidiaries for all purposes (including Tax, federal tax, and financial
accounting purposes) in a manner consistent with Treasury Regulations Section 1
 .338(b)-2T. Buyer shall timely prepare a proposed allocation for review and
approval by Seller, which approval shall not unreasonably be withheld. Buyer,
the Company and its Subsidiaries, and Seller will file, or cause to be filed,
all Tax Returns (including for this purpose all federal, state, local and
foreign income tax returns and including amended returns and claims for refund)
in a manner consistent with the Section 338(h)(10) Election and with such
allocation.

                  9(b) Tax Sharing Agreements. Any Tax sharing agreement between
PacifiCorp and any of the Company and its Subsidiaries is terminated as of the
Closing Date 




                                       39
<PAGE>   45

and will have no further effect for any taxable year (whether the current year,
a future year, or a past year).

                  9(c) Tax Returns. The Company and its Subsidiaries will
furnish Tax information to PacifiCorp for inclusion in Tax Returns for the
period that ends on and includes the Closing Date in accordance with the
Company's past custom and practice. Seller will allow Buyer an opportunity to
review and comment upon such Tax Returns (including any amended returns) to the
extent that they relate to the Company and its Subsidiaries. Seller will cause
PacifiCorp to take no position on such Tax Returns, including any amended
returns, that relate to the Company and its Subsidiaries that would adversely
affect the Company and its Subsidiaries after the Closing Date, unless such
position would be reasonable in the case of a Person that owned the Company and
its Subsidiaries both before and after the Closing Date. Taxes of the Company
and its Subsidiaries will be apportioned to the period up to and including the
Closing Date and the period after the Closing Date by closing the books of the
Company and its Subsidiaries as of the end of the Closing Date. Buyer will
prepare all Tax Returns for Tax periods including, but not ending on, the
Closing Date.

                  9(d) Audits. Seller shall, or shall cause PacifiCorp to keep
the Company informed of the status of any audits of PacifiCorp Tax Returns to
the extent that such returns relate to the Company and its Subsidiaries. Seller
will not, and will cause PacifiCorp not to, settle any such audit in a manner
that would adversely affect the Company and its Subsidiaries after the Closing
Date unless such settlement would be reasonable in the case of a Person that
owned the Company and its Subsidiaries both before and after the Closing Date.
Buyer will keep Seller informed of the status of any audits of Tax Returns that
include Buyer to the extent such returns relate to the Company and its
Subsidiaries. Buyer will not settle any such audit in a manner which would
adversely affect the Company and its Subsidiaries prior to the Closing Date
unless such settlement would be reasonable in the case of a Person that owned
the Company and its Subsidiaries both before and after the Closing Date.

                  9(e) Carrybacks. Seller will, or will cause PacifiCorp to,
immediately pay to the Buyer any Tax refund (or reduction in Tax liability)
resulting from a carryback of a post-acquisition Tax attribute of any of the
Company and its Subsidiaries into the Seller or PacifiCorp Tax Return, when such
refund or reduction is realized by Seller or the PacifiCorp group, but only if
the Company and its Subsidiaries cannot elect to waive the carryback, Seller
will, or will cause PacifiCorp to, cooperate with the Company and its
Subsidiaries in obtaining such refunds (or reduction in Tax liability),
including through the filing of amended Tax Returns or refund claims, provided
that Seller will not be required to participate in obtaining any refund (or
reduction in Tax liability) for which Seller, or its employee responsible for
Taxes, believes in good faith there is not substantial authority. The Buyer
agrees to indemnify Seller and PacifiCorp for any Taxes resulting from the
disallowance of such post-acquisition Tax attribute on audit or otherwise, or
from cooperation with the Company and its Subsidiaries, for example, by filing
an amended Tax Return.




                                       40
<PAGE>   46

                  9(f) Indemnification for Post-Closing Transactions. Buyer
agrees to indemnify Seller and PacifiCorp for any additional Tax owed by Seller
or PacifiCorp (including Tax owed by Seller due to this indemnification payment)
resulting from any transaction not in the Ordinary Course of Business occurring
on the Closing Date after Buyer's purchase of the Company stock, other than any
Tax liabilities attributable to the Section 338(h)(10) Election.

                  9(g) Post-Closing Transactions not in the Ordinary Course.
Buyer and Seller agree to report all transactions not in the Ordinary Course of
Business occurring on the Closing Date, other than any deemed transactions as a
result of the Section 338(h)(10) Election, after Buyer's purchase of the Company
stock on Buyer's federal income tax return to the extent permitted by Treasury
Regulations Section 1. 1502-76(b)(1)(ii)(B).

              10. Termination.

                  10(a) Termination of Agreement. The Parties may terminate this
Agreement as provided below:

                        (i) the Buyer and the Seller may terminate this
              Agreement by mutual written consent at any time prior to the
              Closing;

                        (ii) either the Buyer or the Seller may terminate this
              Agreement by giving written notice to the other at any time prior
              to the Closing in the event (A) the Seller has within the then
              previous five business days given the Buyer any notice pursuant to
              Section 5(e)(i) above which relates to events or occurrences after
              the date of this Agreement; and (B) the development that is the
              subject of the notice has, individually or in the aggregate with
              all the developments with respect to events or occurrences after
              the date of this Agreement for which notice was given pursuant to
              Section 5(e)(i) above, had a Material Adverse Effect;

                        (iii) the Buyer may terminate this Agreement by giving
              written notice to the Seller at any time prior to the Closing (A)
              in the event Seller has breached any material representation,
              warranty, or covenant contained in this Agreement (other than the
              representations and warranties in Section 4 above) in any material
              respect, the Buyer has notified the Seller of the breach, and the
              breach has continued without cure for a period of 10 days after
              the notice of breach or (B) if the Closing shall not have occurred
              on or before December 31, 1997, by reason of the failure of any
              condition precedent under Section 7(a) hereof (unless the failure
              results primarily from the Buyer itself breaching any
              representation, warranty, or covenant contained in this
              Agreement); and

                        (iv) the Seller may terminate this Agreement by giving
              written notice to the Buyer at any time prior to the Closing (A)
              in the event the Buyer has breached 




                                       41
<PAGE>   47

              any material representation, warranty, or covenant contained in
              this Agreement in any material respect, the Seller has notified
              the Buyer of the breach, and the breach has continued without cure
              for a period of ten days after the notice of breach or (B) if the
              Closing shall not have occurred on or before December 31, 1997, by
              reason of the failure of any condition precedent under Section
              7(b) hereof (unless the failure results primarily from any of the
              Seller itself breaching any representation, warranty, or covenant
              contained in this Agreement).

                        10(b) Effect of Termination. If any Party terminates
              this Agreement pursuant to Section 10(a) above, all rights and
              obligations of the Parties hereunder shall terminate without any
              liability of any Party to any other Party (except for any
              liability of any Party then in breach, unless the termination was
              pursuant to Section 10(a)(ii)); provided, however, that the
              confidentiality provisions contained in the Confidentiality
              Agreement shall survive termination.

              11.       Miscellaneous.

                        11(a) Press Releases and Public Announcements. No Party
shall issue any press release or make any public announcement relating to the
subject matter of this Agreement prior to the Closing without the prior written
approval of the Buyer and the Seller; provided, however, that any Party may make
any public disclosure it believes in good faith is required by applicable law or
any listing or trading agreement concerning its publicly-traded securities (in
which case the disclosing Party will use its reasonable best efforts to advise
the other Parties prior to making the disclosure).

                        11(b) No Third Party Beneficiaries. This Agreement shall
not confer any rights or remedies upon any Person other than the Parties and
their respective successors and permitted assigns, provided that PacifiCorp is
an intended third party beneficiary of the provisions of Section 9 above.

                        11(c) Entire Agreement. This Agreement (including the
documents referred to herein) constitutes the entire agreement among the Parties
and supersedes any prior understandings, agreements, or representations by or
among the Parties, written or oral, to the extent they have related in any way
