ITEM 1 -- BUSINESS

GENERAL

     NRG Energy, Inc. (NRG Energy or the Company) is a leading global energy
company, primarily engaged in the acquisition, development, ownership, and
operation of power generation facilities and the sale of energy, capacity and
related products. NRG Energy was incorporated as a Delaware corporation on May
29, 1992. As of December 31, 2000, NRG Energy had interests in power generation
facilities (including those under construction) having a total design capacity
of 25,059 megawatts (MW), of which NRG Energy has or will have total or shared
operational responsibility for 13,784 MW, and net ownership of, or leasehold
interests in, 15,007 MW.

     On June 5, 2000, NRG Energy completed its initial public offering. Prior to
its initial public offering, NRG Energy was a wholly-owned subsidiary of
Northern States Power (NSP). In August 2000, NSP merged with New Century
Energies, Inc. (NCE), a Colorado-based public utility holding company. The
surviving corporation in the merger was renamed Xcel Energy Inc. (Xcel), and the
shares of NRG Energy's class A common stock previously owned by NSP are now
owned by a wholly-owned subsidiary of Xcel. As of December 31, 2000, Xcel owned
an 82% interest in NRG Energy's outstanding common and class A common stock,
representing 98% of the total voting power of NRG Energy's common stock and
class A common stock. Xcel is one of the ten largest electricity and natural gas
companies in the United States. Xcel has six public utility subsidiaries that
collectively serve approximately 3.1 million electricity customers and 1.5
million gas customers in twelve states and has numerous non-utility
subsidiaries, including NRG Energy, which are engaged in energy related
businesses.

     In March 2001, NRG Energy completed a public offering of 18.4 million
shares of its common stock. Following this offering, Xcel owns approximately 74%
interest in NRG Energy's common stock and Class A common stock, representing
96.7% of the total voting power of NRG Energy's common stock and Class A common
stock.

     NRG Energy has experienced significant growth in the last year, expanding
from 10,990 MW of net ownership interests in power generation facilities
(including those under construction) as of December 31, 1999, to 15,007 MW of
net ownership interests as of December 31, 2000. This growth resulted primarily
from a number of domestic and international acquisitions, notably the
acquisition of Big Cajun I and II from Cajun Electric Power Cooperative, Inc.
(Cajun Electric), the Killingholme A generating facility from National Power plc
and the acquisition of Flinders Power in South Australia.

     In addition to NRG Energy's power generation projects, NRG Energy also has
interests in district heating and cooling systems and steam transmission
operations. As of December 31, 2000, NRG Energy's thermal and chilled water
businesses had a steam and chilled water capacity equivalent to approximately
1,506 MW, of which its net ownership interest was 1,379 MW. NRG Energy believes
that through its subsidiary NEO Corporation (NEO), it is one of the largest
landfill gas generation companies in the United States, extracting methane from
landfills to generate electricity. NEO owns 33 landfill gas collection systems
and has 46 MW of net ownership interests in related electric generation
facilities. NEO also has 58 MW of net ownership interests in 19 small
hydroelectric facilities and 6 MW of net ownership interest in three small
distributed generation facilities.

     NRG Energy intends to continue its growth through a combination of targeted
acquisitions in selected core markets, the expansion or repowering of existing
facilities and the development of new greenfield projects. NRG Energy has signed
agreements to acquire an additional 5,704 MW of net ownership interest in
existing generation projects and has acquired or has expansion plans for 5,515
MW of net ownership interest in expansion, repowering and greenfield generation
projects. To prepare for these expansion, repowering and greenfield development
opportunities, NRG Energy has agreed to purchase 22 turbine generators from
General Electric Company and two turbine generators from Seimens Westinghouse
over a five-year period commencing in 2002. These new turbines, which NRG Energy
expects to install at domestic facilities, will

                                        1
<PAGE>   4

have a combined nominal generating capacity of approximately 4,640 MW. In
addition, NRG Energy has on order three General Electric turbines with a
combined nominal capacity of approximately 740 MW scheduled for delivery in
January 2002, which are expected to be installed in facilities outside the
United States. NRG Energy has also acquired the right to purchase an additional
24 General Electric turbines and an additional three Siemens Westinghouse
turbines through its acquisition of assets from LS Power, LLC. These turbines
have a combined generating capacity of approximately 4,306 MW. All but 1,993 MW
of the turbines NRG Energy has on order have been allocated to NRG Energy's
current, identified expansion, repowering or greenfield development projects.

     NRG Energy has also expanded its power marketing activities, which allow
NRG Energy to optimize the value of its power generation assets and enable it to
better meet its customers' energy requirements and improve its power marketing
and risk management expertise. NRG Energy believes that it has secured and will
continue to secure favorable pricing for its fuel purchases and power sales.

     NRG Energy's headquarters and principal executive offices are located at
901 Marquette Avenue, Suite 2300, Minneapolis, Minnesota 55402. NRG Energy's
telephone number is (612) 373-5300.

MARKET OPPORTUNITY

     The power industry is one of the largest industries in the world,
accounting for approximately $220 billion in annual revenues and approximately
810,000 MW of installed generating capacity in the United States alone. The
generation segment of the industry historically has been characterized by
regulated electric utilities producing and selling electricity to a captive
customer base. However, the power generation market has been evolving from a
regulated market based on cost of service pricing to a competitive market. In
response to increasing customer demand for access to low-cost electricity and
enhanced services, new regulatory initiatives have been and are continuing to be
adopted to increase competition in the power industry. NRG Energy believes that
the power generation industry in the United States will experience MW growth of
approximately 2% per year through 2008.

     NRG Energy believes that increasing demand and the need to replace old and
inefficient generation facilities will create a significant need for additional
power generating capacity throughout the United States and the world. In NRG
Energy's view, these factors combined with recent restructuring legislation
provide an attractive domestic environment for a competitive power producer like
NRG Energy with a history of successfully developing, acquiring and operating
power generation facilities.

     Outside of the United States, many governments in developed economies are
privatizing their utilities and developing regulatory structures that are
expected to encourage competition in the electricity sector, having realized
that their energy assets can be sold to raise capital without hindering system
reliability. In developing countries, the demand for electricity is expected to
grow rapidly. In order to satisfy this anticipated increase in demand, many
countries have adopted active government programs designed to encourage private
investment in power generation facilities. NRG Energy believes that these market
trends will continue to create opportunities to acquire and develop power
generation facilities globally.

STRATEGY

     NRG Energy's vision is to be a well-positioned, top three generator of
power in selected core markets. Central to this vision is the pursuit of a
well-balanced generation business that is diversified in terms of geographic
location, fuel type and dispatch level. Currently, approximately 79% of NRG
Energy's net MW of generation in operation and under construction is located in
the United States in four core markets: our Northeast, South Central and West
Coast regions and the recently added North Central region. The North Central
Region was added to manage a newly acquired portfolio of operating projects and
projects in construction and advanced development. Upon completion of NRG
Energy's pending project acquisitions from Conectiv, NRG Energy intends to add a
Mid-Atlantic region as a fifth core market. With NRG Energy's diversified asset
base, NRG Energy seeks to have generating capacity available to back up any
given facility during its outages, whether planned or unplanned, while having
ample resources to take advantage of peak power market price opportunities.
                                        2
<PAGE>   5

     NRG Energy's strategy is to capitalize on its acquisition, development,
construction and operating skills to build a balanced, global portfolio of power
generation assets. NRG Energy intends to implement this strategy by continuing
an aggressive acquisition program and accelerating its development of existing
site expansion projects and greenfield projects. NRG Energy believes that its
operational skills and experience give it a strong competitive position in the
unregulated generation marketplace.

NORTH AMERICAN POWER GENERATION

     The North American power generation market is evolving from a regulated,
utility dominated market based upon cost-of-service pricing to an independent
power generation market based on competitive market pricing. While most domestic
generation capacity is still utility owned and subject to cost-of-service
regulation, NRG Energy expects the evolution to continue as regulated utility
power generation assets are divested to non-regulated generators. In addition,
NRG Energy expects that a significant share of the new generation capacity that
is built to serve increasing demand and to replace less efficient facilities
will be developed and owned by competitive power producers.

     Most of NRG Energy's North American projects are grouped under regional
holding companies corresponding to their domestic core markets. In order to
better manage NRG Energy's North American projects and to develop new projects
in these regions more effectively, NRG Energy has established regional offices
in Pittsburgh, Pennsylvania (Northeast region), Baton Rouge, Louisiana (South
Central region) and San Diego, California (West Coast region). NRG Energy's
recently added North Central region is managed from its Minneapolis
headquarters. Upon completion of NRG Energy's pending project acquisitions from
Conectiv, NRG Energy intends to add a Mid-Atlantic region, which will be managed
from its Wilmington, Delaware office.

     NRG Energy operates its generation facilities within each region as a
separate operating unit within its power generation business. This regional
portfolio structure allows NRG Energy to coordinate the operations of its assets
to take advantage of regional opportunities, reduce risks related to outages,
whether planned or unplanned, and pursue expansion plans on regional basis.

NORTHEAST REGION

     As of December 31, 2000, NRG Energy owned approximately 7,104 MW of net
generating capacity (including projects under construction) in the Northeast
United States, primarily in New York, New Jersey, Connecticut and Massachusetts.
These generation facilities are well diversified in terms of dispatch level
(base-load, intermediate and peaking), fuel type (coal, natural gas and oil) and
customers. In addition, NRG Energy believes certain of its facilities and
facility sites in the Northeast provide opportunities for repowering or
expanding existing generating capacity.

     NRG Energy's Northeast facilities are generally competitively positioned
within their respective market dispatch levels with favorable market dynamics
and locations close to the major load centers in the New York Power Pool (NYPP)
and NEPOOL.

SOUTH CENTRAL REGION

     As of December 31, 2000, NRG Energy owned approximately 2,413 MW of net
generating capacity (including projects under construction) in the South Central
United States, primarily in Louisiana. NRG Energy's South Central generating
assets consist primarily of its net ownership of 1,708 MW of power generation
facilities in New Roads, Louisiana (which are referred to as the Cajun
facilities) that were acquired in March 2000. NRG Energy believes that the Cajun
facilities and related infrastructure provide significant opportunities for
expanding its generating capacity in the region.

WEST COAST REGION

     As of December 31, 2000, NRG Energy owned approximately 1,570 MW of net
generating capacity (including projects under construction) on the West Coast of
the United States. NRG Energy's West Coast generation assets consist primarily
of a 50% interest in West Coast Power LLC (West Coast Power) and a 58% interest
in the Crockett Cogeneration facility. In May 1999, Dynegy Power Corporation
(Dynegy) and
                                        3
<PAGE>   6

NRG Energy formed West Coast Power to serve as the holding company for a
portfolio of operating companies that own generation assets in Southern
California. This portfolio currently comprises the El Segundo Generating
Station, the Long Beach Generating Station, the Encina Generating Station and 17
combustion turbines in the San Diego area. Dynegy provides power marketing and
fuel procurement services to West Coast Power, and NRG Energy provides
operations and management services. NRG Energy believes certain of its
facilities and facility sites on the West Coast provide opportunities for
repowering or expanding generating capacity, and NRG Energy has submitted permit
applications to expand its El Segundo facility.

NORTH CENTRAL REGION

     As of December 31, 2000, NRG Energy owned approximately 175 MW of net
generating capacity in the north central United States, primarily Illinois. In
January 2001, NRG Energy completed its project acquisition from LS Power, LLC of
approximately 5,633 MW of operating projects and projects in construction and
advanced development, 1,697 MW of which are currently in operation, or under
construction.

MID-ATLANTIC REGION

     NRG Energy plans to add a Mid-Atlantic region upon the completion of its
acquisition of approximately 1,875 MW of net ownership interests in generation
facilities from subsidiaries of Conectiv. The Mid-Atlantic region will contain
facilities located primarily in Pennsylvania, Maryland, Delaware and New Jersey.

COMPETITIVE POWER GENERATION -- INTERNATIONAL

     Historically, the majority of power generating capacity outside of the
United States has been owned and controlled by governments. During the past
decade, however, many foreign governments have moved to privatize power
generation plant ownership through sales to third parties and by encouraging new
capacity development and refurbishment of existing assets by independent power
developers. Governments have taken a variety of approaches to encourage the
development of competitive power markets, from awarding long-term contracts for
energy and capacity to purchasers of power generation to creating competitive
wholesale markets for selling and trading energy, capacity and related products.

     NRG Energy believes that there will be significant opportunities to invest
in attractive projects in international markets. Based upon NRG Energy's
assessment of market opportunities and its portfolio risk management criteria,
NRG Energy intends to leverage its reputation, experience and expertise in order
to acquire foreign assets in selected countries. As market opportunities
develop, NRG Energy expects that its international strategy will be consistent
with its domestic core market strategy in terms of geographic, fuel and dispatch
diversification. NRG Energy believes operating and asset diversity will allow it
to reduce business and market risks, while positioning it to take advantage of
market opportunities, including peak power market price opportunities and
periods of constrained availability of generating capacity, fuels and
transmission.

     To manage NRG Energy's international asset portfolio risks, NRG Energy
utilizes a portfolio risk management discipline based upon country risk, as
identified by an independent, internationally recognized organization. This
portfolio tool, which has been endorsed by NRG Energy's board of directors,
requires that it manage its entire portfolio of generation capacity to maintain
a high quality, weighted average, equivalent country risk. Using this tool, NRG
Energy is able to monitor the exposure it is taking in emerging markets to
maintain an appropriate balance in its asset portfolio. NRG Energy's
international power generation projects are managed as three distinct markets,
Asia Pacific, Europe and Other Americas.

     NRG Energy is presently focusing its international development in Europe,
Australia and Latin America. In the future, NRG Energy will consider
international projects outside of these markets if it believes that an
opportunity exists to create a new core market or that the expected returns from
a particular project warrant an investment.

ASIA PACIFIC

     NRG Energy is one of the largest competitive power producers in Australia
with a net ownership interest of 2,083 MW. As of December 31, 2000, in power
generation facilities (including projects under construction). NRG Energy
intends to maintain its position in this market through additional acquisitions
and
                                        4
<PAGE>   7

development of new projects. NRG Energy will also look for opportunities in
selected countries in the Asia Pacific region to become established within the
region.

EUROPE

     NRG Energy has been a significant participant in the competitive power
generation markets in Germany and the Czech Republic since its entry into those
markets. NRG Energy's growth in Europe was augmented in early 2000 with the
acquisition of the Killingholme facility and will expand further with the
expected mid-2001 commencement of commercial operations at the Enfield facility,
both of which are located in the United Kingdom. NRG Energy intends to continue
its growth efforts in these countries and to develop projects in selected
countries. As of December 31, 2000, NRG Energy has a net ownership interest of
1,223 MW in power generation facilities (including projects under construction)
in Europe.

OTHER AMERICAS

     NRG Energy has pursued acquisition and development opportunities in Latin
America since the mid-1990s. Initially, NRG Energy participated as one of four
original sponsors of the Latin Power fund, a private equity investment fund
managed by Scudder. More recently, NRG Energy acquired a 49% interest in the
second largest generator of electricity in Bolivia, Compania Boliviana de
Energia Electrica S.A. -- Bolivian Power Company Limited (COBEE). NRG Energy
plans to target new opportunities in selected countries, primarily Brazil and
Argentina, where NRG Energy believes more attractive acquisition and greenfield
opportunities exist. As of December 31, 2000, NRG Energy has a net ownership
interest of 225 MW in power generation facilities (including projects under
construction) in Latin America.

ALTERNATIVE ENERGY

     NRG Energy provides alternative energy through NEO, one of the largest
landfill gas generation companies in the United States, and resource recovery,
which processes municipal solid waste as fuel used to generate power.

NEO CORPORATION

     NEO is a wholly-owned subsidiary of NRG Energy's that was formed to develop
small power generation facilities, ranging in size from 1 to 50 MW, in the
United States. NEO is currently focusing on the development and acquisition of
landfill gas projects and the acquisition of small hydroelectric projects. NEO
owns 33 landfill gas collection systems and has 46 MW of net ownership interests
in related electric generation facilities. NEO also has 58 MW of net ownership
interests in 19 small hydroelectric facilities and 6 MW of net ownership
interests in three small distributed generation facilities. NEO derives a
substantial portion of its income as a result of the generation of Section 29
tax credits, which, for 2000, totaled $33.8 million. The existing tax law
authorizing these credits is scheduled to expire in 2007.

RESOURCE RECOVERY FACILITIES

     NRG Energy's Newport, Minnesota, resource recovery facility can process
over 1,500 tons of municipal solid waste per day, 90% of which is used as fuel
in power generation facilities in Red Wing and Mankato, Minnesota. Pursuant to
service agreements with Ramsey and Washington Counties, Minnesota, which expire
in 2007, NRG Energy processes a minimum of 280,800 tons of municipal solid waste
per year at the Newport facility and receives service fees based on the amount
of waste processed, pass-through costs and certain other factors. NRG Energy is
also entitled to an operation and maintenance fee, which is designed to recover
fixed costs and to provide NRG Energy with a guaranteed amount for operating and
maintaining the Newport facility for the processing of 750 tons per day of
municipal solid waste, whether or not such waste is delivered for processing.

     Since 1989, NRG Energy has operated the Elk River resource recovery
facility located in Elk River, Minnesota, which can process over 1,500 tons of
municipal solid waste per day, 90% of which is recovered and used in power
generation facilities in Elk River and Mankato, Minnesota. Xcel owns 85% of the
Elk River facility and United Power Association owns the remaining 15%. NRG
Energy also manages and operates an

                                        5

ash storage and disposal facility for the Elk River facility at Xcel's Becker
ash disposal facility, an approved ash deposit site near Becker, Minnesota. NRG
Energy operates the Becker facility on behalf of Xcel.

THERMAL

     NRG Energy has interests in district heating and cooling systems and steam
transmission operations. NRG Energy's thermal and chilled water businesses have
a steam and chilled water capacity equivalent to approximately of 1,506 MW, of
which its net ownership interest is 1,379 MW.

     NRG Energy owns and operates, through its holding company NRG Thermal
Corporation, five district heating and cooling systems in Minneapolis, San
Francisco, Pittsburgh, Harrisburg and San Diego. These systems provide steam
heating to approximately 600 customers and chilled water to 81 customers. In
addition, NRG Energy's thermal division operates five projects that serve
industrial/government customers with high-pressure steam and hot water.

POWER MARKETING

     NRG Energy's energy marketing subsidiary, NRG Power Marketing, Inc. (NRG
Power Marketing), began operations in 1998 to maximize the utilization of and
return from its domestic generation assets and to mitigate the risks associated
with those assets. This subsidiary purchases and markets energy and energy
related commodities, including electricity, natural gas, oil, coal and emission
allowances. By using internal resources to acquire fuel for and to market
electricity generated by its domestic facilities, NRG Energy believes that it
can secure the best pricing available in the markets in which it sells power and
enhance its ability to compete. NRG Power Marketing provides a full range of
energy management services for NRG Energy's generation facilities in its
Northeast, South Central and North Central regions. These services are provided
under power sales and agency agreements pursuant to which NRG Power Marketing
manages the sales and marketing of energy, capacity and ancillary services from
these facilities and also manages the purchase and sale of fuel and emission
allowances needed to operate these facilities.

     NRG Power Marketing conducts its activities in accordance with risk
management guidelines approved by the NRG Power Marketing board of directors,
which has primary responsibility for oversight of NRG Power Marketing
activities. NRG Energy's risk management guidelines require that its treasury
department perform a credit review and approve all counter parties and credit
limits prior to NRG Power Marketing entering into a transaction with such
counter parties. NRG Energy does not engage in speculative trading, thus
transactions are primarily for physical delivery of the particular commodity for
the specified period. These physical delivery transactions may take the form of
fixed price, floating price or indexed sales or purchases, and options on
physical transactions, such as puts, calls, basis transactions and swaps, are
also permitted. Contracts for the transmission and transportation of these
commodities are also authorized, as necessary, in order to meet physical
delivery requirements and obligations. All forward sales and purchases of
electricity and fuel are reported to the board of directors of NRG Power
Marketing and to our Financial Risk Management Committee. In accordance with the
risk management guidelines, no more than 50% of the uncommitted energy or
capacity of any facility will be sold forward without the approval of the board
of directors of NRG Power Marketing. Violation by any employee of any of the
risk management guidelines is grounds for immediate termination of employment.

     NRG Power Marketing handles fuel procurement and trading of emissions
allowances in order to support NRG Energy's overall needs. Generally, NRG Energy
seeks to hedge prices for 50% to 70% of its expected fuel requirements during
the succeeding 12 to 24 month period. This provides NRG Energy with certainty as
to a portion of its fuel costs while allowing it to maintain flexibility to
address lower than expected dispatch rates and to take advantage of the dual
fuel capabilities at many of its facilities.

HOW NRG ENERGY SELLS ITS GENERATING CAPACITY AND ENERGY

     NRG Energy's operating revenues are derived primarily from the sale of
electrical energy, capacity and other energy products from its power generation
facilities. Revenues from these facilities are received pursuant to:

     - long-term contracts of more than one year including:

          - power purchase agreements with utilities and other third parties
            (generally 2-25 years);

          - standard offer agreements to provide load serving entities with a
            percentage of their requirements (generally 4-9 years); and

          - "transition" power purchase agreements with the former owners of
            acquired facilities (generally 3-5 years).

     - short-term contracts or other commitments of one year or less and spot
       sales including:

          - spot market and other sales into various wholesale power markets;
            and

          - bilateral contracts with third parties.

     NRG Energy's objective is to mitigate variability in its earnings by having
approximately 50% of its capacity contracted for under contracts greater than
one year, generally seeking to enter into contracts with lengths of 1-5 years,
selling half of its remaining capacity (25%) in the forward market for 30-365
days, and selling the other half of its remaining capacity (25%) in the spot
market to capture opportunities in the market when prices are higher. By
following this strategy, NRG Energy seeks to achieve positive, stable returns
while retaining the flexibility to capture premium returns when available.

     During 2000, NRG Energy derived approximately 34.4% of its 2000 revenues
from majority owned operations from two customers: New York Independent System
Operator (22.2%) and Connecticut Light and Power Company (12.2%). During 1999,
NRG Energy derived approximately 51.2% of total revenues from wholly owned
operations from three customers: Niagara Mohawk Power Corporation (21%),
Consolidated Edison Company of New York, Inc. (19.7%) and Eastern Utilities
Associates (10.5%).

GEOGRAPHICAL INFORMATION

     For financial information on NRG Energy's operations on a geographical
basis, see Item 8 -- Note 18 to the financial statements.

PLANT OPERATIONS

     NRG Energy's success depends on its ability to achieve operational
efficiencies and high availability at its generation facilities. In the new
unregulated energy industry, minimizing operating costs without compromising
safety or environmental standards while maximizing plant flexibility and
maintaining high reliability is critical to maximizing profit margins. NRG
Energy's operations and maintenance practices are designed to achieve these
goals.

     NRG Energy's overall corporate strategy of establishing a top three
presence in certain core markets is in part driven by its operational strategy.
While NRG Energy's approach to plant management emphasizes the operational
autonomy of its individual plant managers and staff to identify and resolve
operations and maintenance issues at their respective facilities, NRG Energy has
also implemented a regional shared practices system in order to facilitate the
exchange of information and best practices among the plants in its various
regions. NRG Energy has organized its operations geographically such that
inventories, maintenance, backup and other operational functions are pooled
within a region. This approach enables NRG Energy to realize cost savings and
enhances its ability to meet its facility availability goals. Plant supervisors
and staff within core markets and across the company typically participate in
weekly conference calls in order to discuss operational issues and share best
practices.

SIGNIFICANT ASSET AND BUSINESS ACQUISITIONS

     In March 2000, NRG Energy acquired the assets of the Killingholme A
generation facility from National Power plc for L390 million (approximately $615
million at the date of acquisition), subject to post-closing adjustments.
Killingholme is a combined cycle gas-fired baseload facility located in North
Lincolnshire, England. The facility comprises three units with a total
generating capacity of 680 MW. NRG Energy owns and operates the facility, which
sells its power into the wholesale electricity market of England and Wales.

     In March 2000, NRG Energy acquired the Cajun facilities, 1,708 MW of coal
and gas-fired generation assets in Louisiana, for approximately $1,055.9 million
(the Cajun facilities). These assets were formerly owned by Cajun Electric. NRG
Energy acquired these assets as a result of a competitive bidding process
following the Chapter 11 bankruptcy of Cajun Electric.

     In September 2000, NRG Energy completed the acquisition of Flinders Power
in South Australia. NRG Energy paid approximately AUD $314.4 million (U.S. $180
million at the date of acquisition) for a 100-year lease of the Flinders Power
assets. Flinders Power includes two power stations totaling 760 MW. In addition,
NRG Energy received a 20-year lease, renewable for additional 10-year terms, of
the Leigh Creek coal mine and a dedicated rail line. The 100-year lease also
includes managing the long-term fuel supply and power purchase agreement of the
180 MW Osborne Cogeneration Station.

     In January 2001, NRG Energy completed the acquisition of a 5,633 MW
portfolio of operating projects and projects in construction and advanced
development that are located primarily in the north central and south central
United States, from LS Power for $708 million. Approximately 1,697 MW are
currently in operation or under construction, and NRG Energy expects that an
additional $1,850 million will be required to complete projects currently under
construction or about to commence construction. Each facility employs natural
gas-fired, combined-cycle technology. Through December 31, 2005, NRG Energy also
has the opportunity to acquire ownership interests in an additional 3,000 MW of
generation projects developed and offered for sale by LS Power and its partners.

SIGNIFICANT EQUITY INVESTMENTS

     The following are significant equity investments included in NRG Energy's
Independent Power Generation Segment.

                                 LOY YANG POWER

     NRG Energy has a 25.4% interest in Loy Yang Power, which owns and operates
the 2,000 MW Loy Yang A brown coal fired thermal power station and the adjacent
Loy Yang coal mine located in Victoria, Australia. This interest was purchased
for AUD $340 million (approximately US $264.3 million at the time of the
acquisition) in 1997. The power station has four units, each with a 500 MW
boiler and turbo generator, which commenced commercial operation between July
1984 and December 1988. In addition, Loy Yang manages the common infrastructure
facilities that are located on the Loy Yang site, which service not only the Loy
Yang A facility, but also the adjacent Loy Yang B 1,000 MW power station, a
pulverized dried brown coal plant, and several other nearby power stations.

     The wholesale electricity market in Australia is regulated under the
National Electricity Law, which provides for a legally enforceable National
Electricity Code, which defines the market rules. The code also makes provision
for the establishment of the National Electricity Market Management Company to
manage the power system, maintain system security and administer the spot
market. Under the rules of the National Electricity Market, the Loy Yang
facility is required to sell all of its output of electricity through the
competitive wholesale market for electricity operated and administered by the
National Electricity Market.

     Loy Yang Power is subject to a number of senior debt lending covenants.
From 1997 through 1999, energy prices received by Loy Yang were lower than NRG
Energy expected when the assets were purchased. As a result, during 2000, the
company projected that during 2001 it would breach the loan covenants permitting
equity distributions to the project owners. Based upon current forecasts
incorporating improve-

                                        8
<PAGE>   11

ments in the electricity market, indications are that possible future senior
debt covenant breaches forecast in earlier financial reports will not occur. In
the event that the forecast improvements are not achieved, a breach of these
covenants could occur. While Loy Yang Power would still expect to fully service
all of its senior debt payment obligations, senior lenders might exercise their
rights to enforce their securities at that time. NRG Energy could be required to
write-off all or a significant portion of its current $250 million investment in
this project as a result of such enforcement, a determination by the project
company that a write-down of its assets is required or NRG Energy's
determination that it would not be able to recover its investment in this
project.

     Junior debt interest payments to the value of AUD $33.9 (approximately US
$18.9 million ) were accumulated during 2000 and, of this, a payment of $7.8
million (approximately US $4.4 million) was made. Deferred/Accrued Junior debt
interest payments as of December 31, 2000, totaled AUD $36.9 million
(approximately US $20.6 million). Based on current cash forecasts it is possible
that further interest payments on the Junior Debt Facility may also be deferred,
all deferred interest will be paid at a later time as permitted under the
workings of the project financing arrangements.

     In the National Electricity Market power pool system, it is not possible
for a generator such as Loy Yang to enter into traditional power purchase
agreements. In order to provide a hedge against pool price volatility,
generators have entered into "contracts for differences" with distribution
companies, electricity retailers and industrial customers. These contracts for
differences are financial hedging instruments, which have the effect of fixing
the price for a specified quantity of electricity for a particular seller and
purchaser over a defined period.

     In February 2000, CMS Energy announced its intention to divest its 49.6%
ownership in the Loy Yang project but has established no deadline for completion
of the sale. CMS Energy indicated that it intended to sell its interest because
the project was no longer of strategic value to its portfolio and had not met
its financial expectations. Under certain circumstances CMS will require the
approval of Loy Yang Power's lenders and other parties to enable the sale to
proceed. The impact (if any) of the proposed sale on NRG's existing investment
in Loy Yang Power is not known at the date of this report.

                                     MIBRAG

     NRG Energy indirectly purchased a 33 1/3% interest in the equity of
Mitteldeutsche Braunkohlengesellschaft mbH (MIBRAG) in 1994 for $10.6 million.
MIBRAG owns coal mining, power generation and associated operations, all of
which are located south of Leipzig, Germany. MIBRAG was formed by the German
government following the reunification of East and West Germany to hold two
open-cast brown coal (lignite) mining operations, a lease on an additional mine,
three lignite-fired industrial cogeneration facilities and briquette
manufacturing and coal dust plants, all located in the former East Germany.
MIBRAG's cogeneration operations consist of the 110 MW Mumsdorf facility, the 86
MW Deuben facility and the 37 MW Wahlitz facility. These facilities provide
power and thermal energy for MIBRAG's coal mining operations and its briquette
manufacturing plants. All power not consumed by MIBRAG's internal operations is
sold under an eight-year power purchase agreement with Westsachsische Energie
Aktiengesellschaft, a recently privatized German electric utility. MIBRAG's
lignite mine operations include Profen, Zwenkau and Schleenhain with total
estimated reserves of 776 million metric tons, which are expected to last for
more than 40 years. A dispute has arisen as to coal transportation compensation
payments to be made to MIBRAG pursuant to the acquisition agreement by
Bundesanstalt fur vereinigungsbedingte Sonderaufgaben (BvS), a German
governmental entity that facilitated the privatization of MIBRAG. The size of
the annual coal transportation compensation payments fluctuates based on the
volume of coal transported to the Schkopau facility. The payment due for 2000
was approximately 59 million deutsche marks (approximately U.S. $28 million) and
has been received by MIBRAG. However, BvS disputes its obligation to make any
future compensation payments. MIBRAG and BvS are engaged in active discussions
to resolve this disagreement. Although MIBRAG believes that a satisfactory
resolution can be negotiated, if that did not occur and BvS ceased to make any
further annual transportation compensation payments to MIBRAG, but MIBRAG were
nevertheless required to continue to transport coal to the Schkopau facility
without the benefit of these

                                        9
<PAGE>   12

transportation compensation payments at the prices agreed in 1993 when the
compensation and acquisition agreements were negotiated, it would have a
material adverse effect on MIBRAG.

                                     COBEE

     In December 1996, NRG Energy acquired for $81.8 million a 49.1% interest in
COBEE, the second largest generator of electricity in Bolivia. COBEE has entered
into contracts, which expire in 2008, with two Bolivian distribution companies
pursuant to which COBEE supplies electricity. All payments under these contracts
are made in United States dollars.

     COBEE operates its electric generation business under a 40-year concession
granted by the Bolivian government in 1990. Under this concession, COBEE is
entitled to earn a return of 9.0% on assets within its rate base. The Bolivian
Electricity Code also provides for the adjustment of rates to compensate COBEE
for any shortfall or to recapture any excess in COBEE's actual rate of return
during the previous year. COBEE periodically applies to the Superintendent of
Electricity for rate increases sufficient to provide its 9.0% rate of return
based on COBEE's current operating results and its projection of future revenues
and expenses. Under COBEE's concession, COBEE's assets are required to be
removed from the rate base in 2008.

                            GLADSTONE POWER STATION

     The Gladstone facility is a 1,680 MW coal-fired power generation facility
located in Gladstone, Australia. NRG Energy acquired a 37.5% ownership interest
in the Gladstone facility for $64.9 million when the facility was privatized in
March 1994.

     NRG Energy is responsible for the operation and maintenance of the
Gladstone facility pursuant to a 17-year operation and maintenance agreement
that commenced in 1994, which includes an annual bonus based on availability
targets. The Gladstone facility sells electricity to the Queensland Power
Trading Corporation and also to Boyne Smelters Limited. Pursuant to an
interconnection and power pooling agreement, Queensland Power is obligated to
accept all electricity generated by the facility, subject to merit order
dispatch, for an initial term of 35 years.

     Queensland Power also entered into a 35-year capacity purchase agreement
with each of the project's owners for such owner's percentage of the capacity of
the Gladstone facility, excluding that sold directly to Boyne Smelters. Under
the capacity purchase agreements, Queensland Power pays the facility owners both
a capacity and an energy charge. The capacity charge is designed to cover the
projected fixed costs allocable to Queensland Power, including debt service and
an equity return, and is adjusted to reflect variations in interest rates.

     The owners of Boyne Smelters have also entered into a power purchase
agreement with each of the project's owners, providing for the sale and purchase
of such owner's percentage share of capacity allocated to Boyne Smelters. The
term of each of these power purchase agreements is 35 years. The owners of Boyne
Smelters is obligated to pay to each of the project's owners a demand charge
that is intended to cover the fixed costs of supplying capacity to Boyne
Smelters, including debt service and return on equity. The owners of Boyne
Smelters are also obligated to pay an energy charge based on the fuel cost
associated with the production of energy from the Gladstone facility.

                             SCHKOPAU POWER STATION

     In 1993, NRG Energy acquired for $18.2 million an indirect 50% interest in
a German limited liability company, Saale Energie GmbH, which then acquired a
41.9% interest in a 960 MW coal-fired power plant that was under construction in
the East German city of Schkopau. The first 425 MW unit of the Schkopau plant
began operation in January 1996, the 110 MW turbine in February 1996, and the
second 425 MW unit in July 1996. The coal is provided under a long-term contract
by MIBRAG's Profen lignite mine.

                                        10
<PAGE>   13

     Saale Energie sells its allocated 400 MW portion of the plant's capacity
under a 25-year contract with VEAG, a major German utility that controls the
high-voltage transmission of electricity in the former East Germany. VEAG pays a
price that is made up of three components, the first of which is designed to
recover installation and capital costs, the second to recover operating and
other variable costs, and the third to cover fuel supply and transportation
costs. NRG Energy receives 50% of the net profits from these VEAG payments
through its ownership interest in Saale Energie.

                           COLLINSVILLE POWER STATION

     The Collinsville Power Station is a 192 MW coal-fired power generation
facility located in Collinsville, Australia. In March 1996, NRG Energy acquired
a 50% ownership interest in the idled Collinsville facility for $11.9 million
when the Queensland State government privatized it. The Collinsville facility
was recommissioned and commenced operations on August 11, 1998. Transfield
Holdings Pty Ltd, the project's other 50% owner, and NRG Energy have entered
into an 18-year power purchase agreement with Queensland Power under which
Queensland Power will pay both a capacity and an energy charge to the project's
owners. The capacity charge is designed to cover the projected fixed costs
allocable to Queensland Power, including debt service and an equity return. The
energy charge is based on the fuel costs associated with the production of
energy from the facility.

                              ENERGY CENTER KLADNO

     The Energy Center Kladno project, located in Kladno, the Czech Republic
consists of two distinct phases. In 1994, NRG Energy acquired an interest in the
existing coal-fired electricity and thermal energy facility that can supply 28
MW of electrical energy and 150 MW equivalent of steam and heated water. This
facility historically supplied electrical energy to a nearby industrial complex.
The second phase was the expansion of the existing facility, which was completed
in January 2000, by the addition of 345 MW of new capacity, 271 MW of which is
coal-fired and 74 MW of which is gas-fired. The original project is owned by
Energy Center Kladno, a Czech limited liability company in which NRG Energy owns
a 44.26% interest. The expansion is held separately through ECK Generating, a
Czech limited liability company in which NRG Energy owns a 44.50% interest.

                            ENERGY DEVELOPMENTS LTD

     Energy Developments Limited, a publicly traded company listed on the
Australian Stock Exchange, owns and operates approximately 274 MW of generation
primarily in Australia. Between February 1997 and April 1998, NRG Energy
acquired a total of 14,609,670 common shares and 16,800,000 convertible, non-
voting preference shares of Energy Developments. NRG Energy paid a total of
approximately AUD$69.1 million (US$44.5 million at the time of acquisition), or
AUD$2.20 (US$1.42) per share, for the shares, which represent approximately a
29.1% ownership interest in Energy Developments. NRG Energy has agreed to
restrictions on its ability to purchase more shares or to dispose of any
existing shares of Energy Developments. The preference shares do not become
convertible into common shares unless a takeover bid is made for Energy
Developments. In such event, if Energy Developments fails to comply with an
obligation to appoint directors nominated by the owner of the preference shares,
the preference shares can be converted at the option of the owner to common
shares on a share-for-share basis.

                                WEST COAST POWER

     In May 1999, Dynegy and NRG Energy formed West Coast Power, 50% owned by
affiliates of each sponsor. West Coast Power serves as the holding company for a
portfolio of operating companies that own generating assets in Southern
California. These assets are currently comprised of the El Segundo Generating
Station, the Long Beach Generating Station, the Encina Generating Station and 17
Combustion Turbines in the San Diego area (the Encina Combustion Turbines).

                                        11
<PAGE>   14

     El Segundo Generating Station: The El Segundo Generating Station is a 1,020
MW plant consisting of four units: two units at 175 MW each and two units at 335
MW each. El Segundo was purchased from the Southern California Edison Company
through a competitive bid process for $88.3 million during April 1998.

     Long Beach Generating Station: The Long Beach Generating Station is a 560
MW plant with seven 60 MW gas turbine generators and two 70 MW steam turbine
units. The Long Beach plant was purchased from Southern California Edison
Company during March 1998 through a competitive bid process for $29.9 million.

     Encina Generating Station: The Encina Generating Station is located in
Carlsbad, California and consists of five steam-electric generating units and
one combustion turbine with net generating capacity of 965 MW. Encina was
purchased from San Diego Gas & Electric during May 1999, at a purchase price of
$283.2 million.

     Encina Combustion Turbines: The Encina Combustion Turbine assets consist of
17 combustion turbine generator sets (the CT's) with an aggregate capacity of
253 MW, located on seven different sites in San Diego County. During May 1999,
Dynegy and NRG Energy purchased the CT's from San Diego Gas & Electric through a
competitive bid process. The CT's acquisition had a purchase price of $69.1
million. The CT's have the ability to provide spinning reserve, black start
capability, quick start capability, voltage support and quick load capability
for the ancillary services market.

     In December 2000, NRG Energy and its partner submitted permit applications
in respect of a planned repowering of the jointly-owned El Segundo station. The
planned repowering will add approximately 621 MW of generating capacity to the
facility at a cost of approximately $368 million. Prior to the repowering,
approximately 350 MW at the El Segundo Station will be decommissioned. The
repowering project has a targeted operation date of June 2003.

SIGNIFICANT MAJORITY- AND WHOLLY-OWNED OPERATIONS

     The following are significant majority- and wholly-owned operations
included in NRG Energy's Independent Power Generation segment.

                             CROCKETT COGENERATION

     Pacific Crockett Energy, Inc., an indirect, wholly-owned subsidiary of NRG
Energy's, is the general partner of the Crockett Cogeneration Project
(Crockett). Crockett, a 240 MW gas fired plant, began operations in May 1996.
Pacific Generation Company, another wholly-owned subsidiary of the Company, owns
a 56.67 percent limited partnership interest in Crockett through ENI Crockett LP
(ENI Crockett). ENI Crockett is a limited partnership in which Pacific
Generation Company is the general partner and Dynegy is a limited partner. The
project sells 240 MW of capacity and energy to Pacific Gas & Electric Company
under a modified Standard Offer No. 4 Purchase Power 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 adjacent C&H Sugar refinery under a steam sales
agreement that expires in 2026. Natural gas is supplied to the project by BP
Canada Energy Marketing. ESOCO operates the project under a renewable 15 year
contract that provides for reimbursement of all costs within an approved budget,
plus a fee and provision for a performance bonus. Other limited partners include
Energy Investors Fund LP and Energy Investors Fund II, LP and a subsidiary of
Tomen Power Corp. Crockett was originally financed with a $260 million
construction and term loan facility provided by a commercial bank syndicate led
by ABN-AMRO. On December 15, 1999, Crockett was refinanced with a $255 million
term loan facility provided by a commercial bank syndicate led by ABN-AMRO,
maturing in December 31, 2014.

                          NRG NORTHEAST GENERATING LLC

     NRG Energy has acquired, through subsidiaries, in five separate
transactions, certain generating assets from Niagara Mohawk Power Corporation
(NIMO), Consolidated Edison Company of New York (ConEd), Montaup Electric
Company (MEC), a wholly owned subsidiary of Eastern Utilities Association (EUA),
and Connecticut Light & Power Company (CL&P) for a total cost of approximately
$1.5 billion. NRG Energy has aggregated these assets into a regional generating
company, NRG Northeast Generating LLC (NRG Northeast); (collectively, the NRG
Northeast assets).

     The NRG Northeast assets represent competitive, low cost units with
favorable market dynamics and locations close to major load centers in the NYPP
and NEPOOL.

     Huntley and Dunkirk: In June 1999, NRG Energy completed the acquisition of
the Huntley and Dunkirk generating stations from NIMO for $355 million. The two
coal-fired power generation facilities are located near Buffalo, New York and
have a combined capacity rating of 1,360 MW. In connection with this
acquisition, NRG Energy entered into a 4-year agreement with NIMO that requires
NRG Energy to provide to NIMO pursuant to a predetermined schedule fixed
quantities of energy and capacity at a fixed price.

     Oswego: In October 1999, NRG Energy completed the acquisition of the 1,700
MW oil and gas fired Oswego generating station for approximately $85 million
from NIMO and Rochester Gas and Electric Corporation.

     Astoria Gas Turbines and Arthur Kill: In June 1999, NRG Energy completed
the acquisition of the Astoria gas turbine facility and the Arthur Kill
Generating Station from ConEd for $505 million. These facilities, which are
located in the New York City area, have a combined capacity rating of 1,456 MW.

     Somerset: In April 1999, NRG Energy completed the acquisition of the
Somerset power station for approximately $55 million from MEC. The Somerset
station includes two coal fired base-load generating facilities supplying a
total of 181 MW and two aeroderivative combustion turbine peaking units
supplying a total of 48 MW, includes 69 MW on deactivated reserve. It is located
on the west bank of the Taunton River in Somerset, Massachusetts and is
interconnected with the NEPOOL market.

     Connecticut stations: In December 1999, NRG Energy completed the
acquisition of four fossil fuel electric generating stations and six remote gas
turbines totaling 2,235 MW from CL&P for $460 million, plus adjustments for
working capital. The assets acquired from CL&P (CL&P Assets) are comprised of
the Middletown, Montville, Devon and Norwalk Harbor gas- and oil-fired steam
generating stations totaling 2,108 MW and 127 MW of remote gas turbines at
Branford, Torrington and Cos Cob, Connecticut. NRG Energy also entered into a
4-year standard offer agreement that requires NRG Energy to provide to CL&P a
portion of its load requirements through the year 2003 at a substantially fixed
price.

     Middletown station, an 856 MW gas and oil powered plant, is located in
Middletown, Connecticut. The 498 MW Montville Station in Uncasville, Connecticut
is composed of one gas- or oil-fired unit, one oil-fired unit and two diesel
generators. Norwalk Station, with 353 MW of capacity from two oil-fired units
and one gas turbine, is located on Manresa Island at the mouth of Norwalk
Harbor. Devon Station, consisting of 401 MW of generation capacity derived from
two gas- or oil-fired units and five gas turbines, is located at Milford,
Connecticut.

                        NRG SOUTH CENTRAL GENERATING LLC

     In March 2000, the Cajun facilities were acquired in a competitive bidding
process following a Chapter 11 bankruptcy filing by their former owner, Cajun
Electric. NRG Energy paid approximately $1,055.9 million for these facilities.
The Cajun facilities consist of 100% of two gas-fired intermediate/peaking power
generation units with a total capacity of 220 MW, which NRG Energy collectively
refers to as Big Cajun I, and two coal-fired, base-load power generation units
with a total capacity of 1,150 MW, and a 58% interest in a third coal-fired,
base load unit with a total capacity of 575 MW, which NRG Energy refers to
collectively as Big Cajun II.

                                        13
<PAGE>   16

     NRG Energy believes the bankruptcy of Cajun Electric resulted from Cajun
Electric's inability to service approximately $2,200 million in secured debt
provided in part by the Rural Utilities Service of the United States Department
of Agriculture, most of which was incurred as a result of the purchase by Cajun
Electric of a 30% interest in the River Bend Nuclear Station Unit 1, a nuclear
power generation facility located in Saint Francisville, Louisiana. Cajun
Electric's 30% interest in the River Bend nuclear facility was transferred to
Entergy Gulf States in December 1997. NRG Energy has no ownership interest in
the River Bend nuclear facility or responsibility for any indebtedness of Cajun
Electric to the Rural Utilities Service or otherwise.

     NRG Energy sells most of the energy and capacity of the Cajun facilities to
11 of Cajun Electric's former power cooperative members. Seven of these
cooperatives have entered into 25-year power purchase agreements with NRG
Energy, and four have entered into two to four year power purchase agreements.
In addition, NRG Energy sells power under contract to two municipal power
authorities and one investor-owned utility that were former customers of Cajun
Electric.

                                  KILLINGHOLME

     In March 2000, NRG Energy acquired the 680 MW gas-fired Killingholme
combined cycle, baseload facility in North Lincolnshire, England from National
Power plc. The purchase price was (pounds)390 million (approximately U.S. $615.0
million at the time of acquisition), subject to post closing adjustments. NRG
Energy financed the acquisition with a 19-year non-recourse credit facility that
provides for (pounds)235 million (approximately U.S. $374 million at the time of
acquisition) for the costs of the acquisition and (pounds)90 million
(approximately U.S. $143 million at the time of acquisition) for letters of
credit and working capital needs. NRG Energy sells power from the facility into
the wholesale electricity market of England and Wales. The facility has a ten
and one half year contract to purchase up to 70% of its natural gas requirements
from a subsidiary of Centrica plc. From January 1, 2000 through the date of the
acquisition, NRG Energy entered into a tolling agreement with National Power
pursuant to which NRG Energy received revenues based on the prevailing market
prices for electricity in exchange for payments to National Power based on the
incremental operating costs of the facility.

     NRG Energy anticipates that prices for power in the wholesale electricity
market of England and Wales will decrease over the short term due to new trading
rules that are expected to come into effect and increase competition in this
market. This expected market trend was taken into account when NRG Energy bid to
acquire this facility. NRG Energy has entered into short-term agreements to sell
a portion of the output of the Killingholme facility, and, in the future, NRG
Energy intends to enter into similar short-term and long-term agreements that
will provide a degree of stability to its revenues from the facility.

                                 FLINDERS POWER

     In September 2000, NRG Energy completed the acquisition of Flinders Power,
South Australia's final generation company to be privatized. NRG Energy paid
approximately AUD $314.4 million (approximately U.S. $180 million at the date of
acquisition) for a 100-year lease of certain Flinders Power assets, including
two power stations totaling 760 MW. In addition, NRG Energy received a 20-year
lease, renewable for additional 10-year terms, for the Leigh Creek coal mine and
a dedicated rail line. The 100-year lease agreement also includes managing the
long-term fuel supply and power purchase agreement of the 180 MW Osborne
Cogeneration Station.

                               LS POWER PROJECTS

     In January 2001, NRG Energy completed the acquisition of a 5,633 MW
portfolio of operating projects and projects in construction and advanced
development from LS Power, LLC for approximately $708 million, subject to
purchase price adjustments. Approximately 1,697 MW are currently in operation or
under construction, and NRG Energy expects that an additional $1,850 million
will be required to complete construction of the projects currently under
construction or about to commence construction. Each facility employs natural
gas-fired combined cycle technology. Through 2005, NRG has the opportunity to
acquire
                                        14
<PAGE>   17

ownership interests in an additional 3,000 MW of generation projects developed
and offered for sale by LS Power and its partners.

SIGNIFICANT PENDING ACQUISITIONS AND PROJECTS UNDER DEVELOPMENT

     Due to the many complexities inherent in the acquisition, development and
financing of projects, there can be no assurance that any of NRG Energy's
pending acquisitions and projects under development, including those described
below, will be consummated.

                                     TURKEY

     In 1999, NRG Energy and its partners were selected as the winning bidder
for the 600 MW Seyitomer Power Station and related lignite mine in Kuthya,
Turkey. Seyitomer is NRG Energy's second successful bid in Turkey. In 1998, also
with partners, NRG Energy won a bid to acquire the 450 MW coal-fired Kangal
plant and lignite mine in central Turkey. A law has been introduced in the
Turkish parliament that would require these projects, among others, to close by
June 30, 2001 or be cancelled. NRG Energy is working to meet this deadline.

                                    ESTONIA

     In June 2000, the Estonian cabinet approved the terms under which NRG
Energy may proceed to purchase a 49% interest in Narva Power, which owns
approximately 3,000 MW of oil shale-fired generation plants and a 51% interest
in state-owned oil shale mines. In August 2000, NRG Energy signed a Heads of
Terms Agreement with Eesti Energia, the Estonian state-owned electric utility,
providing for the purchase, for approximately $65.5 million, of a 49% stake in
Narva Power, the owner-operator of the oil shale fired Eesti and Balti power
plants located near Narva, Estonia. A government-owned entity, Eesti-Energia,
will retain 51% ownership of Narva Power. Narva Power's two stations, Balti and
Eestia, currently supply more than 90% of Estonia's electricity, and have a
combined capacity of approximately 2,700 MW. NRG Energy is working to close the
acquisition in the second quarter of 2001.

                                CONECTIV ASSETS

     In January 2000, NRG Energy executed purchase agreements with Conectiv to
acquire 1,875 MW of coal, gas and oil fired electric generating capacity and
other assets located in New Jersey, Delaware, Maryland and Pennsylvania. NRG
Energy will pay approximately $800 million for the assets. The fossil-fueled
generating facilities consist of Conectiv's wholly owned BL England, Deepwater,
Indian River and Vienna steam stations plus Conectiv's interest in the Conemaugh
(7.55%)and Keystone (6.17%) steam stations in Pennsylvania. Other assets in the
purchase are the 241-acre Dorchester site located in Dorchester County,
Maryland, certain Merrill Creek Reservoir entitlements in Harmony Township, New
Jersey and certain excess emission allowances. NRG Energy will sell 500 MW of
capacity and associated energy to Delmarva (a subsidiary of Conectiv) under a
five-year power purchase agreement commencing upon the closing of the
acquisition. The remaining energy and capacity will be sold in PJM and
neighboring markets. Closing of the acquisition has been delayed pending receipt
of required regulatory approvals. NRG Energy expects to close the acquisition in
the second quarter of 2001.

     The BL England Steam Station is a 447 MW coal and oil-fired generating
facility in Beesley's Point, New Jersey. The Deepwater steam station is a 239 MW
gas, oil and coal facility near Pensville, New Jersey. The Indian River Steam
Station is a 784 MW coal fired facility near Millboro, Delaware. The Vienna
Steam Station is a 170 MW oil-fired generating station located in the town of
Vienna, Maryland. Of the 1,711 MW coal-fired Conemaugh Steam Station, located
near Pittsburgh, Pennsylvania, NRG Energy will acquire a 7.55% ownership or 129
MW of generation. NRG Energy will also acquire a 6.17% ownership or 106 MW in
the 1,711 MW coal-fired Keystone Steam Station also located near Pittsburgh,
Pennsylvania.

                       PARTNERSHIP WITH AVISTA-STEAG LLC

     In November 2000, NRG Energy agreed to form a partnership with Avista-STEAG
LLC to build, operate and manage a 633 MW natural gas-fired power plant in Fort
Bend County, Texas. NRG Energy expects to own 50% of the project. NRG Energy's
investment in the project is expected to total approximately $163 million.
Construction is scheduled to begin in early 2001, with commercial operation
expected in February 2003.

                        BRIDGEPORT AND NEW HAVEN HARBOR

     In December 2000, NRG Energy signed asset purchase agreements to acquire
the 585 MW coal fired Bridgeport Harbor Station and the 466 MW oil and gas fired
New Haven Harbor Station in Connecticut from Wisconsin Energy Corporation for
$325 million, subject to purchase price adjustments. The acquisition is subject
to regulatory and other conditions and is expected to close during the second
quarter of 2001.

                   REID GARDNER AND CLARK GENERATING STATIONS

     In November 2000, Dynegy Inc. and NRG Energy executed asset purchase
agreements to acquire the 740 MW gas fired Clark Generating Station and 445 MW
of the 605 MW coal-fired Reid Gardner Generating Station, both of which are near
Las Vegas, Nevada. The purchase price is approximately $634 million, subject to
purchase price adjustments. The acquisition is subject to regulatory and other
conditions. Although NRG Energy is working to close the acquisition during the
second quarter of 2001, legislation has been recently introduced in the Nevada
legislature that, if passed as introduced, would prohibit the sale of the Reid
Gardner and Clark stations. In addition, the Public Utilities Commission of
Nevada has commenced a proceeding that could reverse its original requirement
that these plants be sold. Finally, NRG Energy and Dynegy are negotiating to
acquire an additional 145 MW of the Reid Gardner Station.

                                  NORTH VALMY

     In October 2000, NRG Energy signed an asset purchase agreement to acquire
from Sierra Pacific Resources its 50% interest in the 522 MW coal fired North
Valmy Generating Station located in Valmy, Nevada, and a 100% interest in 25 MW
of peaking units near the North Valmy Station. Idaho Power, the other 50% owner
of the North Valmy Station, has a 180-day right of first refusal on purchasing
this 50% interest. The right of first refusal expires in May 2001. In addition,
the California legislature recently enacted legislation prohibiting any public
utility subject to regulation by the California Public Utilities Commsion from
selling any generating asset until 2006. This law applies to Sierra Pacific
Resources because approximately 10% of its rate payers are located in
California. NRG Energy is working to have legislation introduced to exempt the
North Valmy Station and the peaking units from application of this law.

                                    MERIDEN

     In December 2000, NRG Energy signed a purchase agreement to acquire a 540
MW natural gas fired generation facility being developed in Meriden,
Connecticut, for a purchase price of approximately $25 million. NRG Energy
expects to close the acquisition during the second quarter of 2001. NRG Energy
estimates the costs to complete construction of the plant to be approximately
$384 million, which has a planned commercial operation date of June 2003.

                                    AUDRAIN

     In February 2001, NRG Energy signed a purchase agreement to acquire an
approximately 640 MW natural gas fired power plant currently under construction
in Audrain County, Missouri, from Duke Energy North America LLC. NRG Energy
expects the acquisition to close during the second quarter of 2001, with
commercial operation of the plant commencing in June 2001.

REGULATION

     NRG Energy is subject to a broad range of federal, state and local energy
and environmental laws and regulations applicable to the development, ownership
and operation of its United States and international projects. These laws and
regulations generally require that a number of permits and approvals be obtained
before construction or operation of a power plant commences and that, after
completion, the facility operate in compliance with local requirements. NRG
Energy strives to comply with the terms of all such laws, regulations, permits
and licenses and believes that all of its operating plants are in material
compliance with all such applicable requirements. No assurance can be given,
however, that in the future all necessary permits and approvals will be obtained
and all applicable statutes and regulations complied with. In addition,
regulatory compliance for the construction of new facilities is a costly and
time-consuming process, and intricate and rapidly changing environmental
regulations may require major expenditures for permitting and create the risk of
expensive delays or material impairment of project value if projects cannot
function as planned due to changing regulatory requirements or local opposition.
Furthermore, there can be no assurance that existing regulations will not be
revised or that new regulations will not be adopted or become applicable to NRG
Energy which would have an adverse impact on its operations.

     In particular, the competitive power markets in the United States, United
Kingdom, Australia and other countries are dependent on the existing regulatory
structure, and while NRG Energy strives to take advantage of the opportunities
created by regulatory changes, it is impossible to predict the impact of
regulatory changes on its operations. Further, NRG Energy believes that the
level of environmental awareness and enforcement is growing in most countries,
including most of the countries in which NRG Energy intends to develop and
operate new projects. Based on current trends, NRG Energy believes that the
nature and level of environmental regulation to which it is subject will become
more stringent. NRG Energy's policy is therefore to operate its projects in
accordance with applicable local law or relevant environmental guidelines
adopted by the World Bank, whichever reflects the more stringent level of
control.

COMPETITION

     The independent power industry is characterized by numerous strong and
capable competitors, some of which may have more extensive operating experience,
more extensive experience in the acquisition and development of power generation
facilities, larger staffs or greater financial resources than NRG Energy does.
Many of NRG Energy's competitors also are seeking attractive power generation
opportunities, both in the Untied States and abroad. This competition may
adversely affect NRG Energy's ability to make investments or acquisitions. In
recent years, the independent power industry has been characterized by increased
competition for asset purchases and development opportunities.

     In addition, regulatory changes have also been proposed to increase access
to transmission grids by utility and non-utility purchasers and sellers of
electricity. Industry deregulation may encourage the disaggregation of
vertically integrated utilities into separate generation, transmission and
distribution businesses. As a result, significant additional competitors could
become active in the generation segment of the industry.

     The United States electric utility industry is currently experiencing
increasing competitive pressures, primarily in wholesale markets, as a result of
consumer demands, technological advances, greater availability of natural
gas-fired generation that is more efficient than NRG Energy's generation
facilities and other factors. The Federal Energy Regulatory Commission (FERC)
has implemented and continues to propose regulatory changes to increase access
to the nationwide transmission grid by utility and non-utility purchasers and
sellers of electricity. In addition, a number of states are considering or
implementing methods to introduce and promote retail competition. Recently, some
utilities have brought litigation aimed at forcing the renegotiation or
termination of power purchase agreements requiring payments to owners of QF
projects based upon past estimates of avoided cost that are now substantially in
excess of market prices. In the future, utilities, with the approval of state
public utility commissions, could seek to abrogate their existing power purchase
agreements.

     Proposals have been introduced in Congress to repeal PURPA and PUHCA, and
FERC has publicly indicated support for the PUHCA repeal effort. If the repeal
of PURPA or PUHCA occurs, either separately or as part of legislation designed
to encourage the broader introduction of wholesale and retail competition, the
                                        17
<PAGE>   20

significant competitive advantages that independent power producers currently
enjoy over certain regulated utility companies would be eliminated or sharply
curtailed, and the ability of regulated utility companies to compete more
directly with independent power companies would be increased. To the extent
competitive pressures increase and the pricing and sale of electricity assumes
more characteristics of a commodity business, the economics of domestic
independent power generation projects may come under increasing pressure.
Deregulation may not only continue to fuel the current trend toward
consolidation among domestic utilities, but may also encourage the
disaggregation of vertically-integrated utilities into separate generation,
transmission and distribution businesses.

     In addition, the independent system operators who oversee most of the
wholesale power markets have in the past imposed, and may in the future continue
to impose, price limitations and other mechanisms to address some of the
volatility in these markets. For example, the independent system operator for
the New York power Pool and the California independent system operator have
recently imposed price limitations. These types of price limitations and other
mechanisms in New York, California, the New England Power Pool and elsewhere may
adversely impact the profitability of NRG Energy's generation facilities that
sell energy into the wholesale power markets. Finally, the regulatory and
legislative changes that have recently been enacted in a number of states in an
effort to promote competition are novel and untested in many respects. These new
approaches to the sale of electric power have very short operating histories,
and it is not yet clear how they will operate in times of market stress or
pressure. Given the extreme volatility and lack of meaningful long-term price
history in many of these markets and the imposition of price limitations by
independent system operators.

ENVIRONMENTAL MATTERS

     The construction and operation of power projects are subject to extensive
environmental protection and land use regulation in the United States. These
laws and regulations often require a lengthy and complex process of obtaining
licenses, permits and approvals from federal, state and local agencies. If such
laws and regulations are changed and NRG Energy's facilities are not
grandfathered, extensive modifications to project technologies and facilities
could be required.

     Most of the foreign countries in which NRG Energy owns or may acquire or
develop independent power projects have laws or regulations relating to the
ownership or operation of electric power generation facilities. These laws and
regulations are typically significant for independent power producers because
they are still changing and evolving in many countries.

     NRG Energy retains appropriate advisors in foreign countries and seeks to
design its international development and acquisition strategy to comply with and
take advantage of opportunities presented by each country's energy laws and
regulations. There can be no assurance that changes in such laws or regulations
could not adversely affect NRG Energy's international operations.

     NRG Energy and its subsidiaries continue to strive to achieve compliance
with all environmental regulations currently applicable to their operations.
However, it is not possible at this time to determine when or to what extent
additional facilities or modifications of existing or planned facilities will be
required as a result of changes to environmental regulations, interpretations or
enforcement policies or, generally, what effect future laws or regulations may
have upon NRG Energy's operations. For more information on Environmental Matters
see Note 17 to the Financial Statements under Item 8.

EMPLOYEES

     At December 31, 2000, NRG Energy had 2,934 employees, approximately 424 of
whom are employed directly by NRG Energy and approximately 2,510 of whom are
employed by its wholly owned subsidiaries and affiliates. Approximately 1,496
employees are covered by bargaining agreements. NRG Energy has experienced no
significant labor stoppages or labor disputes at its facilities.

       a result of the California energy crisis, which could result in NRG
       Energy's failure to obtain regulatory approvals required to close project
       acquisitions, and which could adversely affect the continued deregulation
       of the electric industry;

     - Other business or investment considerations that may be disclosed from
       time to time in NRG Energy's Securities and Exchange Commission filings
       or in other publicly disseminated written documents, including NRG

ITEM 3 -- LEGAL PROCEEDINGS

FORTISTAR CAPITAL V. NRG ENERGY

     In July 1999, Fortistar Capital Inc., a Delaware corporation, filed a
complaint in District Court (Fourth Judicial District, Hennepin County) in
Minnesota against NRG Energy asserting claims for injunctive relief and for
damages as a result of NRG Energy's alleged breach of a confidentiality letter
agreement with Fortistar relating to the Oswego facility.

     NRG Energy disputed Fortistar's allegations and has asserted numerous
counterclaims. NRG Energy has counterclaimed against Fortistar for breach of
contract, fraud and negligent misrepresentations and omissions, unfair
competition and breach of the covenant of good faith and fair dealing. NRG
Energy seeks, among other things, dismissal of Fortistar's complaint with
prejudice and rescission of the letter agreement.

     A temporary injunction hearing was held on September 27, 1999. The
acquisition of the Oswego facility was closed on October 22, 1999, following
notification to the court of Oswego Power LLC's and Niagara Mohawk Power
Corporation's intention to close on that date. On January 14, 2000, the court
denied Fortistar's request for a temporary injunction. In April and December
2000, NRG Energy filed summary judgment motions to dispose of the litigation. A
hearing on these motions was held in January 2001. A ruling on these motions has
not yet been issued. NRG Energy intends to continue to vigorously defend the
suit and believes Fortistar's complaint to be without merit. No trial date has
been set.

NEW YORK DEPARTMENT OF ENVIRONMENTAL CONSERVATION NOTICE OF VIOLATION

     On May 25, 2000 the New York Department of Environmental Conservation
issued a Notice of Violation to NRG Energy and the prior owner of the Huntley
and Dunkirk facilities relating to physical changes made at those facilities
prior to our assumption of ownership. The Notice of Violation alleges that these
changes represent major modifications undertaken without obtaining the required
permits. Although NRG Energy has a right to indemnification by the previous
owner for fines, penalties, assessments, and related losses resulting from the
previous owner's failure to comply with environmental laws and regulations, if
these facilities did not comply with the applicable permit requirements, NRG
Energy could be required, among other things, to install specified pollution
control technology to further reduce air emissions from the Dunkirk and Huntley
facilities and NRG Energy could become subject to fines and penalties associated
with the current and prior operation of the facilities. NRG Energy is currently
in settlement discussions with the Department of Environmental Conservation and
the State Attorney General's office.

CALIFORNIA LITIGATION

     NRG Energy and other power generators and power traders have been named as
defendants in certain private plaintiff class actions filed in the Superior
Court of the State of California for the County of San Diego in San Diego,
California on November 27, 2000 (Pamela R. Gorden v. Reliant Enegy, Inc., et
al.) and November 29, 2000 (Ruth Hendricks v. Dynegy Power Marketing Inc., et
al.), and in the Superior Court of the State of California, City and County of
San Francisco (Pier 23 Restaurant v. PG&E Energy Trading, et al., filed January
16, 2001 in the Superior Court of the State of California for the County of San
Diego, brought by three California water districts, as consumers of electricity
(Sweetwater Authority v. Dynegy Inc., et al.), and in a suit filed on January
18, 2001 in Superior Court of the State of California, County of San Francisco,
brought by the San Francisco City Attorney on behalf of the People of the State
of California (The People of the State of California v. Dynegy Power Marketing,
Inc., et al.). Although the complaints contain a number of allegations, the
basic claim is that, by underbidding forward contracts and exporting electricity
to surrounding markets, the defendants, acting in collusion, were able to drive
up wholesale prices on the Real Time and Replacement Reserve markets, through
the Western Systems Coordinating Council and otherwise.

                                        26
<PAGE>   29

The complaints allege that the conduct violated California antitrust and unfair
competition laws. NRG Energy does not believe that it has engaged in any illegal
activities, and intends to vigorously defend these lawsuits. While these cases
are in too preliminary a stage to speculate on their outcome, if they were
ultimately resolved adversely to the defendants it could have a material adverse
effect on NRG Energy's results of operations and financial condition.

     There are no other material legal proceedings pending to which NRG Energy
is a party. There are no material legal proceedings to which an officer or
director is a party or has a material interest adverse to NRG Energy or its
subsidiaries. There are no other material administrative or judicial proceedings
arising under environmental quality or civil rights statutes pending or known to
be contemplated by governmental agencies to which NRG Energy is or would be a
party.

FOR THE YEAR ENDED DECEMBER 31, 2000 COMPARED TO THE YEAR ENDED DECEMBER 31,
1999

     For the year ended December 31, 2000, net income was $182.9 million
compared to $57.2 million for 1999, an increase of $125.7 million or 219.8%.
This increase was due to the factors described below.

REVENUES AND EQUITY IN EARNINGS OF UNCONSOLIDATED AFFILIATES

     For the year ended December 31, 2000, NRG Energy had total revenues and
equity earnings of $2,157.9 million, compared to $500.0 million for the year
ended December 31, 1999, an increase of $1,657.9 million or 331.6%. NRG Energy's
operating revenues from majority-owned operations were $2,018.6 million compared
to $432.5 million, an increase of $1,586.1 million or 366.7%. The increase in
revenues from majority-owned operations is primarily due to increased sales
resulting from recently completed acquisitions of electric generating
facilities, primarily during the later portion of 1999 and the first and third
quarters of 2000. During the later portion of 1999, NRG Energy acquired certain
electric generating facilities in the northeastern region of the United States.
In addition, NRG Energy acquired certain electric generating facilities located
in Louisiana and the United Kingdom at the end of the first quarter of 2000.
During the third quarter of 2000, NRG Energy acquired Flinders Power and certain
thermal operations. In addition, NRG Energy's increased ownership in Crockett
Cogeneration has contributed significantly to its revenue growth during 2000, as
compared to 1999.

     For the year ended December 31, 2000, NRG Energy had equity in earnings of
unconsolidated affiliates of $139.4 million, compared to $67.5 million for the
year ended December 31, 1999, an increase of $71.9 million or 106.5%. The
increase in equity earnings of unconsolidated affiliates is due primarily to NRG
Energy's investment in West Coast Power LLC, which benefited from favorable
market conditions in California. In addition, NRG Energy's investment in Rocky
Road LLC, in the fourth quarter of 1999, also contributed favorably to the
increase in equity earnings, compared to the prior year. These increases were
partially offset by reductions in the earnings attributable to NRG Energy's
international equity investments and its investment in NEO Corporation. NEO
Corporation derives a significant portion of its net income from Section 29 tax
credits. NRG Energy does not expect its investment in West Coast Power LLC to
generate similar earnings in the year 2001.

OPERATING COSTS AND EXPENSES

     For the year ended December 31, 2000, cost of majority-owned operations,
was $1,289.5 million, compared to $269.9 million, an increase of $1,019.6
million or 377.8%. For the year ended December 31, 2000 and 1999, cost of
majority-owned operations represented 59.8% and 54.0% of total operating
revenues and equity earnings, respectively.

     For the year ended December 31, 2000, the increase of $1,019.6 million is
primarily due to NRG Energy's recent acquisitions of electric generating
facilities during the later portion of 1999 and primarily the first and third
quarters of 2000. During the later portion of 1999, NRG Energy acquired certain
electric generating facilities in the northeastern region of the United States.
In addition, NRG Energy acquired certain electric generating facilities located
in Louisiana and the United at the end of the first quarter of 2000. During the
third quarter of 2000, NRG Energy acquired Flinders Power and certain thermal
operations. In addition, NRG Energy's ownership in Crockett Cogeneration has
contributed significantly to the growth the cost of majority-owned operations
during 2000, as compared to 1999.

DEPRECIATION AND AMORTIZATION

     For the year ended December 31, 2000, depreciation and amortization was
$122.9 million, compared to $37.0 million for the year ended December 31, 1999,
an increase of $85.9 million or 232.1%. This increase is primarily due to the
addition of property, plant and equipment related to NRG Energy's recently
completed acquisitions of electric generating facilities during the later
portion of 1999 and primarily the first and third quarters of 2000. In addition
the consolidation of NRG Energy's investment in Crockett Cogeneration at the end
of 1999 also contributed to the increase in depreciation and amortization during
2000. Through these acquisitions NRG Energy's net property, plant and equipment
balance has grown to $4,041.7 million at the end of 2000 from $1,975.4 million
at the end of 1999, an increase of $2,066.3 million or 104.6%.

GENERAL, ADMINISTRATIVE AND DEVELOPMENT

     For the year ended December 31, 2000, general, administrative and
development costs were $172.5 million, compared to $83.6 million, an increase of
$88.9 million or 106.4%. This increase is primarily due to increased business
development activities, associated legal, technical and accounting expenses,
employees and equipment resulting from expanded operations and pending
acquisitions. NRG Energy's asset base has grown to $5,978.9 million at the end
of 2000, compared to $3,431.7 million at the end of 1999, an increase of
$2,547.2 million or 74.2%. NRG Energy expects this trend to continue as it
continues to be successful in expanding its operations through closure of its
pending acquisitions and business development activities.

OTHER INCOME (EXPENSE)

     For the year ended December 31, 2000, total other expense was $297.4
million, compared to $78.4 million for the year ended December 31, 1999, an
increase of $219.0 million or 279.3%.

     The increase in total other expense of $219.0 million, as compared to 1999,
consisted primarily of an increase in Interest expense and Minority interest in
earnings of consolidated subsidiary. These increases were partially offset by
decreases in other income, net and gain on sale of interest in projects, in
comparison to 1999.

     For the year ended December 31, 2000, interest expense (which includes both
corporate and project level interest expense) was $293.9 million, as compared to
$93.4 million in 1999, an increase of $200.5 million or 214.8%. This increase is
due to increased corporate and project level debt issued during 2000 as compared
to 1999. During 2000, NRG Energy issued substantial amounts of long term debt at
both the corporate level (recourse debt) and project level (non-recourse debt)
to either directly finance the acquisition of electric generating facilities or
refinance short term bridge loans incurred to finance such acquisitions. NRG
Energy's outstanding long-term debt balances have grown to $3,797.3 million at
the end of 2000 from $1,971.9 million at the end of 1999. The growth of such
outstanding debt balances has contributed directly to the growth in interest
expense during 2000 as compared to 1999.

     For the year ended December 31, 2000, minority interest in earnings of
consolidated subsidiaries was $11.3 million, compared to $2.5 million, an
increase of $8.8 million or 361.5% as compared to 1999. The increase is due to
the consolidation of NRG Energy's 58% interest in Crockett Cogeneration at the
end of 1999 and the recognition of the minority interest in the project.

     For the year ended December 31, 2000, NRG Energy did not recognize any
gains on the sale of any project interests. During 1999 NRG Energy recognized a
gain of $11.0 million related to the reduction in its ownership of Cogeneration
Corporation of America (CogenAmerica). For the year ended December 31, 2000,
other income, net, was $7.9 million, as compared to $6.4 million, for the year
ended December 31, 1999, an increase of $1.5 million, or 22.2%. Other income,
net consists primarily of interest income on loans to affiliates, and
miscellaneous other items, including the income statement impact of certain
foreign currency translation adjustments and the impact of project write-downs
and gains and losses on the dispositions of investments. The increase of $1.5
million is primarily due to an increase in interest income in 2000.

INCOME TAX

     For the year ended December 31, 2000, income tax expense was $92.7 million,
compared to an income tax benefit of $26.1 million, an increase of $118.8
million or 455.6%, compared to 1999. The increase in tax expense in 2000
compared to 1999 is due primarily to higher domestic taxable income. This
increase was partially offset by additional IRC Section 29 energy credits. For
the year ended December 31, 2000, NRG Energy's overall effective income tax rate
was approximately 34%. NRG Energy's effective income tax rate before recognition
of tax credits is 46%. This rate is higher than a combined federal and Minnesota
statutory rate because a significant portion of NRG Energy's income is generated
in New York City, an area with high state and local tax rates. In addition, NRG
Energy has recorded a valuation allowance on certain state and foreign tax
losses, also increasing the effective tax rate.

FOR THE YEAR ENDED DECEMBER 31, 1999 COMPARED TO THE YEAR ENDED DECEMBER 31,
1998

     Net income for the year ended December 31, 1999, was $57.2 million, an
increase of $15.5 million or 37.1%, compared to net income of $41.7 million in
the same period in 1998. This increase was due to the factors described below.

REVENUES AND EQUITY IN EARNINGS OF UNCONSOLIDATED AFFILIATES

     For the year ended December 31, 1999, NRG Energy had total revenues of
$500.0 million, compared to $182.1 million for the year ended December 31, 1998,
an increase of $317.9 million or 174.5%. NRG Energy's operating revenues from
wholly owned operations for the twelve months ended December 31, 1999 were
$432.5 million, an increase of $332.1 million, or 330.7%, over the same period
in 1998. Approximately $303.6 million of the increase in revenues was due to the
acquisition of the NRG Northeast assets during 1999. Approximately $29.1 million
of the increase is due to increased revenues due to the consolidation of
Pittsburgh and San Francisco Thermal and the consolidation of Crockett
Cogeneration during 1999. These increases in revenues were partially offset by a
drop in the processing rates received by NRG Energy's resource recovery
operations. For the twelve months ended December 31, 1999, revenues from wholly
owned operations consisted primarily of revenue from electrical generation
(78.3%), heating, cooling and thermal activities (17.6%) and technical services
(4.1%).

     Equity in earnings of unconsolidated affiliates was $67.5 million for the
year ended December 31, 1999, compared to $81.7 million for the year ended
December 31, 1998, a decrease of $14.2 million or 17.4%. The decrease was due to
a $12.8 million reduction in earnings for NRG Energy's interest in the West
Coast power generation facilities resulting from unfavorable weather conditions
during the summer of 1999 compared to the summer of 1998, which was more
favorable than normal. In addition, the results of operations of the West Coast
facilities were adversely impacted by project level debt that was issued during
the year. Equity earnings were also reduced by lower earnings at Mt. Poso, by
the consolidation of NRG Energy's Thermal operations and Crockett Cogeneration
subsidiaries during 1999 and by an unfavorable currency translation adjustment
relating to the Kladno project. These reductions were partially offset by a
favorable legal settlement at CogenAmerica and increased earnings from MIBRAG.

OPERATING COSTS AND EXPENSES

     Cost of wholly owned operations was $269.9 million for the year ended
December 31, 1999. This is an increase of $217.5 million or 414.9% over the same
period in 1998. Approximately $194.9 million of this increase was due to the
acquisition of the NRG Northeast assets during 1999. The remaining increase was
due to the consolidation of NRG Energy's Thermal operations and the addition of
new projects during 1999 by NRG Energy's NEO subsidiary. Cost of operations, as
a percentage of revenues from wholly owned operations for the year, was 62.4%,
which is 10.2 percentage points higher than the same period in 1998.

     Depreciation and amortization costs were $37.0 million for the year ended
December 31, 1999, compared to $16.3 million for the year ended December 31,
1998. The increase in depreciation and amortization was due primarily to the
addition of the NRG Northeast assets and the addition of new projects by NRG
Energy's NEO subsidiary during 1999. In addition, depreciation and amortization
also increased due to the consolidation of NRG Energy's Thermal operations and
Crockett Cogeneration in 1999.

     General, administrative and development costs were $83.6 million for the
year ended December 31, 1999, compared to $56.4 million for the year ended
December 31, 1998. Approximately $8.0 million of the increase was due to the
acquisition of the NRG Northeast assets during 1999. The remaining increase was
due primarily to increased business development activities and increased legal,
technical, and accounting expenses resulting from expanded operations. As a
percent of total revenues, administrative and general expenses declined to 16.7%
from 31.0% during the same period one-year earlier.

                                        31
<PAGE>   34

OTHER INCOME (EXPENSE)

     Minority interest in projects was $2.5 million for the twelve-month period
compared to $2.3 million for the same period in 1998. Minority interest relates
to certain Pacific Generation projects that were acquired in November 1997 and
certain Thermal operations which have a minority interest.

     In December 1999, NRG Energy sold a portion of its interest in
CogenAmerica, an affiliate of NRG Energy, for a pretax gain of approximately
$11.0 million ($4.1 million after-tax) to Calpine. NRG Energy retained a 20%
interest in CogenAmerica.

     Interest expense was $93.4 million for the twelve months ended December 31,
1999 compared with $50.3 million for the twelve months ended December 31, 1998.
The increase in interest expense was due primarily to the acquisition of the NRG
Northeast assets and the incremental interest expense resulting from the $686.5
million of project level debt issued by NRG Northeast Generating LLC and to the
issuance by NRG Energy of $300 million and $240 million of senior notes in June
1999 and November 1999, respectively. Additionally, a higher average outstanding
balance of NRG Energy's revolving line of credit and the consolidation of
Crockett Cogeneration and NRG Energy's Thermal operations contributed to higher
interest expense.

INCOME TAX

     NRG Energy has recognized an income tax benefit due to the recognition of
certain tax credits. The net income tax benefit for the year ended December 31,
1999, increased by $0.4 million to $26.1 million as compared to $25.7 million in
the same period one year earlier. The increase in tax benefits for the twelve
month period was due to increased interest expense on domestic debt, project
write downs and an increase in Section 29 credits related to NRG Energy's NEO
subsidiary operations and foreign tax benefits associated with the Loy Yang
project, which was substantially offset by higher overall earnings.

LIQUIDITY AND CAPITAL RESOURCES

     To date, NRG Energy and its subsidiaries have obtained cash from
operations, issuance of debt and equity securities, borrowings under credit
facilities, capital contributions from Xcel, reimbursement by Xcel of tax
benefits pursuant to a tax sharing agreement and proceeds from non-recourse
project financings. NRG Energy has used these funds to finance operations,
service debt obligations, fund the acquisition, development and construction of
generation facilities, finance capital expenditures and meet other cash and
liquidity needs.

     Net cash provided by operating activities increased during 2000 compared
with 1999, primarily due to increased earnings during the year, increased
depreciation and amortization and deferred income tax and investment tax
credits, non-cash reductions in earnings and improved working capital. Cash
provided by operating activities in 1999 decreased compared to 1998, primarily
due to a decrease in working capital due to a timing of cash flows.

<PAGE>   35

     Net cash provided by financing activities during 2000 increased, compared
to 1999, primarily due to the issuance of debt and equity securities to finance
asset acquisitions. Net cash provided by financing activities during 1999
increased, compared to 1998, primarily due to the issuance of debt and capital
contributions from NRG Energy's parent to finance asset acquisitions.

PROSPECTIVE CAPITAL REQUIREMENTS

     As of December 31, 2000, NRG Energy estimates its capital expenditure
program to be approximately $6,500 million for the period 2001 - 2005. NRG
Energy expects to spend approximately $3,138 million in 2001, $1,341 million in
2002 and $1,517 million in 2003. These estimated expenditures are primarily for
NRG Energy's project acquisition and development program. For 2001, NRG Energy's
capital requirements reflect the expected acquisition of existing generating
facilities, including the Conectiv assets, North Valmy, LS Power, Reid Gardner
and Clark assets and the Bridgeport and New Haven Harbor facilities as well as
certain other projects under construction.

     NRG Energy's capital expenditure program is subject to continuing review
and modification. Actual expenditures may differ significantly depending upon
such factors as the success, timing of and the level of involvement in projects
under consideration.

CAPITAL SOURCES

     NRG Energy expects to meet its future financing requirements through a
combination of internally generated cash, corporate and project level long term
and short term debt, equity securities and equity like securities. NRG Energy
has generally financed the acquisition and development of its projects under
financing arrangements to be repaid solely from each of its project's cash
flows, which are typically secured by the plant's physical assets and equity
interests in the project company.

     Financing needs are subject to continuing review and can change depending
on market and business conditions and changes, if any, in the capital
requirements of NRG Energy and its subsidiaries.

     During the second quarter of 2000, NRG Energy completed its initial public
offering of 32.4 million shares priced at $15 per share. Upon completion of the
offering, Xcel owned approximately 147.6 million Class A common shares or 82% of
NRG Energy's outstanding common shares. The net proceeds of approximately $453.7
million were used primarily to repay short-term debt and for general corporate
purposes.

     During March of 2001, NRG Energy raised net proceeds of approximately
$473.9 million through a second common stock offering of 18.4 million shares of
common stock. In addition, approximately $278.4 million of net proceeds was
raised through the issuance of 11.5 million equity units. Each equity unit
initially comprises a $25 principal amount of NRG Energy's senior debentures and
an obligation to acquire shares of NRG Energy's common stock no later then May
18, 2004. A portion of the combined net proceeds were used to repay a $600
million bridge credit agreement entered into in January 2001 to acquire certain
generating facilities and projects from LS Power; the remaining net proceeds
will be used for general corporate purposes.

NRG REVOLVING CREDIT FACILITY

     NRG Energy is in the process of structuring and marketing an up to $2.5
billion revolving funding program, which will be used to finance a significant
portion of its U.S. acquisitions and development projects over the next five
years. This revolving credit facility will allow NRG Energy to procure temporary
funding for both the non-recourse debt portion as well as equity contributions
for new projects through an expedient and simplified review and approval
process. NRG Energy is permitted under the revolver to repay borrowed funds,
thus making them available to be borrowed again. NRG Energy plans to do that by
refinancing projects in the long-term capital or bank markets when construction
projects reach commercial operation or when market conditions are favorable. Any
unutilized borrowing capacity may be deployed for future projects.

REGISTRATION STATEMENT

     In December 2000, NRG Energy filed a universal shelf registration statement
with the SEC. Based on this registration, NRG Energy can issue up to $1,650
million of debt securities, preferred stock, common stock, depositary shares,
warrants and convertible securities. This registration statement includes $150
million of securities that are being carried forward from a previous shelf
registration. During March 2001, NRG Energy issued 18.4 million shares of common
stock and 11.5 million corporate units under this shelf registration.

SHORT TERM BORROWING ARRANGEMENT

     For information on NRG Energy's short term borrowing arrangements, see Item
8 -- Note 9 to the Financial Statements.

ACCOUNTING CHANGES

     In June 1998, the Financial Accounting Standards Board (the FASB) issued
Statement of Financial Accounting Standards No. 133, Accounting for Derivative
Instruments and Hedging Activities (SFAS No. 133), subsequently amended by SFAS
No. 137 and SFAS No. 138. SFAS No. 133 requires NRG Energy to record all
derivatives on the balance sheet at fair value. Changes in derivative fair
values will either be recognized in earnings as offsets to the changes in fair
value of related hedged assets, liabilities and firm commitments or, for
forecasted transactions, deferred and recorded as a component of other
accumulated comprehensive income until the hedged transactions occur and are
recognized in earnings. The ineffective portion of a hedging derivative's change
in fair value will be immediately recognized in earnings.

     SFAS No. 133 will apply to NRG Energy's energy and energy related
commodities financial instruments, long-term power sales contracts and long-term
gas purchase contracts used to mitigate variability in earnings due to
fluctuations in spot market prices, hedge fuel requirements at generation
facilities and protect investment in fuel inventories. SFAS No. 133 will also
apply to various interest rate swaps used to mitigate the risks associated with
movements in interest rates.

     NRG Energy has adopted SFAS No. 133 effective January 1, 2001. The effect
of adopting SFAS No. 133 was as follows:

     - A one-time after-tax unrealized loss of $22.6 million recorded to other
       accumulated comprehensive income related to the initial adoption of SFAS
       No. 133 during the quarter ended March 31, 2001, and

     - Increased volatility in future earnings is possible due to the impact of
       market fluctuations on derivative instruments used by NRG Energy.

     In September 2000, the FASB issued Statement No. 140, Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities-
A Replacement of FASB Statement No. 125 (SFAS No. 140). SFAS No. 140 revises the
standards for accounting for securitizations and other transfers of financial
assets and collateral and requires certain disclosures, but it carries over most
of SFAS No. 125's provisions without reconsideration. SFAS No. 140 is effective
for NRG Energy's fiscal year ending December 31, 2001. The adoption of SFAS No.
140 is not expected to have a significant impact on NRG Energy's consolidated
financial position or results of operations.

CALIFORNIA LIQUIDITY CRISIS

     NRG Energy owns approximately 1,569 MW of net generating capacity in
California, which represented approximately 11% of its net MW of operating
projects and projects under construction as of December 31, 2000. Due to the
acquisition and construction of projects outside of California, NRG Energy
expects that by December 31, 2001, this percentage will decrease to
approximately 7% of its net MW of operating projects and projects under
construction. Net income from NRG Energy's California assets represented
approximately 33% of its net income in 2000. Due both to the acquisition and
construction of projects outside of California and to an expected decrease in
earnings from NRG Energy's California assets, NRG Energy expects this percentage
will decrease to approximately 14% of its net income in 2001.

     NRG Energy's California generation assets consist primarily of interests in
the Crockett and Mt. Poso facilities and a 50% interest in West Coast Power LLC,
formed in 1999 with Dynegy Inc. Through the California Power Exchange (PX) and
the California Independent System Operator (ISO), the West Coast Power
facilities sell power to Pacific Gas and Electric Company (PG&E), Southern
California Edison Company (SCE), and San Diego Gas and Electric Company (SDG&E),
the three major California investor-owned utilities. Crockett, Mt. Poso and
certain of NRG Energy's other California facilities also sell directly to PG&E,
SCE and SDG&E. The liquidity crisis faced by both PG&E and SCE, as a result of
tight electricity supplies, rising wholesale electric prices and caps on the
rates that PG&E and SCE may charge their retail customers, has caused both PG&E
and SCE to partially suspend payments to the California PX and the California
ISO.

     NRG Energy's share of the total amounts owed to its California affiliates
by the California PX, the California ISO, and the three major California
utilities totaled approximately $303 million as of February 28, 2001, based upon
financial information provided to NRG Energy by such affiliates. This total
amount consists of NRG Energy share of (a) accounts receivable, which
constituted a majority of such total amount, and (b) amounts that are currently
treated as "disputed revenues" and are not recorded as accounts receivable in
the financial statements of NRG Energy's California affiliates. In March 2001,
certain affiliates of West Coast Power entered into an agreement with the
California Department of Water Resources pursuant to which these affiliates have
agreed to sell up to 1,000 MW to CDWR for the remainder of 2001 and up to 2,300
MW from January 1, 2002 through December 31,2004.

     NRG Energy believes at this time that the amounts that have been recorded
as accounts receivable will ultimately be collected in full; however, if some
form of financial relief or support is not provided to PG&E and SCE, the
collectibility of these receivables will become more questionable in terms of
both timing and amount. With respect to disputed revenues, these amounts relate
to billing disputes arising in the ordinary course of business and to disputes
that have arisen as a result of the California ISO imposing various revenue caps
on the wholesale price of electricity. None of these disputed revenues will be
recorded in the financial statements of NRG Energy's California affiliates until
after the particular issue that caused them to be excluded from the financial
statements is resolved.

     The FERC has jurisdiction over sales for resale of electricity in the
California wholesale power markets. In March 2001, FERC issued orders that
presumptively approved prices up to $273/MWh during January 2001 and $430/MWh
during February 2001. The orders direct electricity suppliers to either refund a
portion of their January and February sales or justify prices charged above
these approved prices. The orders, if finalized, could require West Coast Power
to refund approximately $45 million in revenues from January and February, of
which NRG Energy's share would be approximately $22.5 million. Dynegy Power
Marketing, Inc., as the power marketer for West Coast Power, has submitted
notice of its intent to submit information justifying each component of the
prices charged.

     The delayed collection of receivables owed to West Coast Power resulted in
a covenant default under its credit agreement. West Coast Power is working with
its lenders to secure their agreement to forbear exercising their remedies under
the credit agreement with respect to such covenant default. While a similar
covenant default could be called under NRG Energy's Crockett facilities credit
agreement, NRG Energy is working with the lenders under that agreement to avert
a default. Defaults under the Crockett and West Coast Power credit agreements do
not trigger defaults under any of NRG Energy corporate-level financing
facilities.

     Various legislative, regulatory and legal remedies to the liquidity crisis
faced by PG&E and SCE have been implemented or are being pursued. Assembly Bill
1X,which authorizes the California Department of Water Resources to enter into
contracts for the purchase of electric power through January 1, 2003 and to
issue revenue bonds to fund such purchases, was signed into law by the Governor
of California on February 1, 2001. Assembly Bill 18X, which provides a framework
for the recovery of PG&E and SCE's uncollected expenses for purchasing power for
delivery to their retail customers, is currently under consideration in the
California legislature. Additionally, on March 27, the California Public
Utilities Commission (PUC) approved an approximately 40% increase in the energy
component of the retail electric rates paid by certain

                                        35
<PAGE>   38

California rate payers. This proposed increase would be in addition to the 9%
increase approved in January and a 10% increase expected to take effect next
year. The PUC also ordered the utilities to pay qualifying facilities for power
delivered on a go-forward basis. However, the order did not address repayment of
amounts already owed for past deliveries.

ITEM 7 A -- QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     NRG Energy uses a variety of financial instruments to manage its exposure
to fluctuations in foreign currency exchange rates on its international project
cash flows, interest rates on its cost of borrowing and energy and energy
related commodities prices.

CURRENCY EXCHANGE RISK

     NRG Energy has an investment in the Kladno project in the Czech Republic.
Statement of Financial Accounting Standard (SFAS) No. 52, Foreign Currency
Translation, requires foreign currency gains and losses to flow through the
income statement if settlement of an obligation is in a currency other than the
local currency of the entity. A portion of the Kladno project debt is in a
non-local currency (U.S. dollars and German deutsche marks). As of December 31,
2000, if the value of the Czech koruna decreases by 10 percent in relation to
the U.S. dollar and the German deutsche mark, NRG Energy would record a $3.6
million loss (after tax) on the currency transaction adjustment. If the value of
the Czech koruna increased by 10 percent, NRG Energy would record a $3.6 million
gain (after tax) on the currency transaction adjustment. These currency
fluctuations are inherent to the debt structure of the project and not
indicative of the long-term earnings potential of the investment. Kladno is the
only project NRG Energy has at this time with this type of debt structure.

INTEREST RATE RISK

     NRG Energy has historically used interest rate hedging contracts to
mitigate the risks associated with movements in interest rates and, when deemed
appropriate, has entered into swap agreements effectively converting floating
rate obligations into fixed rate obligations. As of December 31, 2000, NRG
energy had four-interest rate swap agreements with notional amounts totaling
approximately $530 million. If the swaps had been discontinued on December 31,
2000, NRG Energy would have owed the counter parties approximately $28.9
million. Based on the investment grade rating of the counter parties, NRG Energy
believes that its exposure to credit risk due to nonperformance by the counter
parties to its hedging contracts is insignificant.

     - NRG Energy entered into a swap agreement effectively converting 6.96%
       floating rate on AUD$105 million debt into fixed rate debt. The swap
       expires on September 8, 2012.

     - A second swap effectively converts a $16 million issue of non-recourse
       variable rate debt into a fixed rate debt. The swap expires on September
       30, 2002 and is secured by the Camas Power Boiler assets.

     - A third swap converts $177 million of non-recourse variable rate debt
       into fixed rate debt. The swap expires on December 17, 2014 and is
       secured by the Crockett Cogeneration assets.

     - A fourth swap converts (pounds) 188 million of non-recourse variable rate
       debt into fixed rate debt. The swap expires on June 30, 2019 and is
       secured by the Killingholme assets.

     NRG Energy and its subsidiaries have both long and short term-debt
instruments that subject it to the risk of loss associated with movements in
market interest rates. As of December 31, 2000, NRG Energy does not have a
material interest rate exposure as a result of interest rate swaps, which
convert floating rate debt into fixed rate debt.

COMMODITY PRICE RISK

     NRG Energy is exposed to commodity price variability in electricity,
emission allowances and natural gas, oil and coal used to meet fuel
requirements. To manage earnings volatility associated with these commodity
price risks, NRG Energy enters into financial instruments, which may take the
form of fixed price, floating price or indexed sales or purchases, and options,
such as puts, calls, basis transactions and swaps.

                                        36
<PAGE>   39

     NRG Energy utilizes a "Value-at-Risk" (VAR) model to determine the maximum
potential three-day loss in the fair value of the commodity price related
financial instruments. Various modeling techniques can be used in VAR
computations. The VAR for NRG Energy assumes a 95% confidence interval and
reflects NRG Energy's merchant strategy, the generation assets, load obligations
and bilateral physical and financial transactions of NRG Energy. The volatility
estimate is based on a lognormal calculation of closing prices for the latest 30
days for forward markets where NRG Energy has exposure. This model encompasses
the following generating regions, Entergy, NEPOOL and NYPP. NRG Energy is in the
process of expanding the model into other geographic areas.

     The estimated maximum potential three-day loss in fair value of the
commodity price related financial instruments, calculated using the VAR model is
as follows:

CREDIT RISK

     NRG Energy is exposed to credit risk in its risk management activities.
Credit risk relates to the risk of loss resulting from the nonperformance by a
counter party of its contractual obligations. NRG Energy maintains credit
policies intended to minimize overall credit risk and actively monitors these
policies to reflect changes in scope of operations. NRG Energy conducts standard
credit reviews for all of its counter parties.

NOTE 1 -- ORGANIZATION

     NRG Energy, Inc., (NRG Energy), was incorporated as a Delaware Corporation
on May 29, 1992. Beginning in 1989, NRG Energy conducted business through its
predecessor companies, NRG Energy, Inc. and NRG Group, Inc., Minnesota
corporations, which were merged into NRG Energy subsequent to its incorporation.
NRG Energy and its wholly owned subsidiaries and affiliates are principally
engaged in the acquisition, development, construction, ownership, operation and
maintenance of power generation facilities and the sale of energy, capacity and
related products.

     On June 5, 2000, NRG Energy completed its initial public offering. Prior to
completing its initial public offering, NRG Energy was a wholly owned subsidiary
of Northern States Power Company (NSP). During August 2000, NSP and New Century
Energies, Inc. completed their merger. The surviving company operates under the
new name Xcel Energy, Inc. (Xcel). The shares of NRG Energy's class A common
stock previously held by NSP are now owned by Xcel. As of December 31, 2000,
Xcel owned an 82% interest in NRG Energy's outstanding common and class A common
stock, representing 98% of the total voting power of NRG Energy's common stock
and class A common stock.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

     The consolidated financial statements include NRG Energy's accounts and
those of its subsidiaries. All significant intercompany transactions and
balances have been eliminated in consolidation. Accounting policies for all of
NRG Energy's operations are in accordance with accounting principles generally
accepted in the United States of America. As discussed in Note 6, NRG Energy has
investments in partnerships, joint ventures and projects for which the equity
method of accounting is applied. Earnings from equity in international
investments are recorded net of foreign income taxes.

CASH AND CASH EQUIVALENTS

     Cash equivalents include highly liquid investments (primarily commercial
paper) with an original maturity of three months or less at the time of
purchase.

RESTRICTED CASH

     Restricted cash consists primarily of cash collateral for letters of credit
issued in relation to project development activities and funds held in trust
accounts to satisfy the requirements of certain debt agreements.

INVENTORY

     Inventory is valued at the lower of average cost or market and consists
principally of fuel oil, spare parts, coal, kerosene and raw materials used to
generate steam.

PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are capitalized at original cost. Significant
additions or improvements extending asset lives are capitalized, while repairs
and maintenance are charged to expense as incurred. Depreciation is computed
using the straight-line method over the following estimated useful lives:

<TABLE>
<S>                                                             <C>
Facilities and improvements.................................    10-45 years
Machinery and equipment.....................................     7-30 years
Office furnishings and equipment............................      3-5 years
</TABLE>

     The assets and related accumulated depreciation amounts are adjusted for
asset retirements and disposals with the resulting gain or loss included in
operations. NRG Energy analyzes property, plant and equipment quarterly for
potential impairment, assessing the appropriateness of lives and recoverability
of net balances in

                                        44
<PAGE>   47

accordance with Statement of Financial Accounting Standards No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
of (SFAS No. 121).

     Long-lived assets and intangibles are reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. Recoverability of assets to be held and used is measured
by a comparison of the carrying amount of the assets to the future net cash
flows expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying amount or fair value less
the cost to sell.

CAPITALIZED INTEREST

     Interest incurred on funds borrowed to finance projects expected to require
more than three months to complete is capitalized. Capitalization of interest is
discontinued when the project is completed and considered operational.
Capitalized interest is amortized using the straight-line method over the useful
life of the related project. Capitalized interest was approximately $2,667,000,
$287,000, and $172,000 in 2000, 1999 and 1998, respectively.

DEVELOPMENT COSTS AND CAPITALIZED PROJECT COSTS

     Development costs and capitalized project costs include third party
professional services, permits, and other costs which are incurred incidental to
a particular project. Such costs are expensed as incurred until an acquisition
agreement or letter of intent is signed, and the project has been approved by
NRG Energy's Board of Directors. Additional costs incurred after this point are
capitalized. When project operations begin, previously capitalized project costs
are reclassified to investment in projects and amortized on a straight-line
basis over the lesser of the life of the project's related assets or revenue
contract period.

DEBT ISSUANCE COSTS

     Costs to issue long-term debt are capitalized and amortized over the terms
of the related debt.

INTANGIBLES

     Intangibles consist principally of the excess of the cost of investment in
subsidiaries over the underlying fair value of the net assets acquired and are
amortized using the straight-line method over 20 to 30 years. NRG Energy
evaluates the recovery of goodwill and other intangibles quarterly, based on an
analysis of estimated undiscounted future cash flows.

OTHER LONG TERM ASSETS

     Other long-term assets consist primarily of service agreements and
operating contracts. These assets are being amortized over the remaining terms
of the individual contracts, which range from seven to thirty years.

INCOME TAXES

     NRG Energy is included in the consolidated tax returns of Xcel. NRG Energy
calculates its income tax provision on a separate return basis under a tax
sharing agreement with Xcel as discussed in Note 10. Current federal and state
income taxes are payable to or receivable from Xcel. NRG Energy records income
taxes using the liability method. Income taxes are deferred on all temporary
differences between pretax financial and taxable income and between the book and
tax bases of assets and liabilities.

     Deferred taxes are recorded using the tax rates scheduled by law to be in
effect when the temporary differences reverse. NRG Energy's policy for income
taxes related to international operations is discussed in Note 10.

                                        45
<PAGE>   48

REVENUE RECOGNITION

     Revenues from the sale of electricity and steam are recorded based upon the
output delivered and capacity provided at rates as specified under contract
terms or prevailing market rates. Revenues and related costs under cost
reimbursable contract provisions are recorded as costs are incurred. Anticipated
future losses on contracts are charged against income when identified. Several
of NRG Energy's power plants rely on one power sales contract with a single
customer for the majority of the plant's revenues. The prolonged failure of any
of these customers to fulfill contractual obligations or make required payments
could have a substantial negative impact on NRG Energy's results of operations.

     NRG Energy enters into financial instrument contracts to hedge purchase and
sale commitments, fuel requirements and inventories to minimize the risk of
market fluctuations. Gains and losses on these hedge transactions are recognized
into income in the periods for which the underlying commodity is hedged.

FOREIGN CURRENCY TRANSLATION

     The local currencies are generally the functional currency of NRG Energy's
foreign operations. Foreign currency denominated assets and liabilities are
translated at end-of-period rates of exchange. Revenues, expenses and cashflows
are translated at weighted-average rates of exchange for the period. The
resulting currency adjustments are accumulated and reported as a separate
component of stockholders' equity.

CONCENTRATIONS OF CREDIT RISK

     Financial instruments which potentially subject NRG Energy to
concentrations of credit risk consist primarily of cash, accounts receivable,
and notes receivable. Cash accounts are generally held in federally insured
banks. Accounts receivable and notes receivable are concentrated within entities
engaged in the energy industry. These industry concentrations may impact NRG
Energy's overall exposure to credit risk, either positively or negatively, in
that the customers may be similarly affected by changes in economic, industry or
other conditions. Receivables are generally not collateralized; however, NRG
Energy believes the credit risk posed by industry concentration is offset by the
diversification and creditworthiness of its customer base. See Note 17.

DERIVATIVE FINANCIAL INSTRUMENTS

     In the normal course of business, NRG Energy employs a variety of
off-balance sheet instruments to manage its exposure to fluctuations in foreign
currency exchange rates, interest rates and energy and energy related
commodities prices. NRG Energy does not enter into transactions for speculative
purposes. Accordingly, NRG Energy classifies its derivative financial
instruments as held or issued for purposes other than trading.

Foreign currency exchange rates

     To preserve the U.S. dollar value of projected foreign currency cash flows,
NRG Energy may hedge, or protect, those cash flows if appropriate foreign
hedging instruments are available. The gains and losses on those agreements
offset the effect of exchange rate fluctuations on NRG Energy's known and
anticipated cash flows. NRG Energy defers gains on agreements that hedge firm
commitments of cash flows, and accounts for them as part of the relevant foreign
currency transaction when the transaction occurs. NRG Energy defers expected
losses on these agreements, unless it appears that the deferral would result in
recognizing a loss later.

Interest rates

     From time to time NRG Energy uses interest rate hedging instruments to
protect it from an increase in the cost of borrowing. Gains and losses on
interest rate hedging instruments are reported as part of the asset for
Investment In Projects when the hedging instrument relates to a project that has
financial statements that are not consolidated into NRG Energy's financial
statements. Otherwise, these gains and losses are reported as part of debt.

                                        46
<PAGE>   49

Energy and energy related commodities

     NRG Energy is exposed to commodity price variability in electricity,
emission allowances, natural gas, oil and coal used to meet fuel requirements.
In order to manage these commodity price risks, NRG Energy enters into
transactions for physical delivery of particular commodities for a specific
period. These financial instruments are used to hedge physical deliveries, which
may take the form of fixed price, floating price or indexed sales or purchases,
and options, such as puts, calls, basis transactions and swaps. These
transactions are utilized to:

     - Manage and hedge fixed-price purchase and sales commitments;

     - Reduce exposure to the volatility of spot market prices;

     - Hedge fuel requirements at generation facilities; and

     - Protect investment in fuel inventories.

USE OF ESTIMATES

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of
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.

     In recording transactions and balances resulting from business operations,
NRG Energy uses estimates based on the best information available. Estimates are
used for such items as plant depreciable lives, tax provisions, uncollectible
accounts and actuarially determined benefit costs, among others. As better
information becomes available (or actual amounts are determinable), the recorded
estimates are revised. Consequently, operating results can be affected by
revisions to prior accounting estimates.

NEW ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board (the FASB) issued
Statement No. 133, Accounting for Derivative Instruments and Hedging Activities
(SFAS No. 133), subsequently amended by SFAS No. 137 and SFAS No. 138. SFAS No.
133 requires NRG Energy to record all derivatives on the balance sheet at fair
value. Changes in derivative fair values will either be recognized in earnings
as offsets to the changes in fair value of related hedged assets, liabilities
and firm commitments, or, for forecasted transactions, deferred and recorded as
a component of other accumulated comprehensive income until the hedged
transactions occur and are recognized in earnings. The ineffective portion of a
hedging derivative's change in fair value will be immediately recognized in
earnings.

     SFAS No. 133 will apply to NRG Energy's energy and energy related
commodities financial instruments, long-term power sales contracts and long-term
gas purchase contracts used to mitigate variability in earnings due to
fluctuations in spot market prices, hedge fuel requirements at generation
facilities and protect investment in fuel inventories. SFAS No. 133 will also
apply to various interest rate swaps used to mitigate the risks associated with
movements in interest rates.

     NRG Energy has adopted SFAS No. 133 effective January 1, 2001. The effect
of adopting SFAS No. 133 was as follows:

     - A one-time after-tax unrealized loss of approximately $22.6 million
       recorded to other accumulated comprehensive income related to the initial
       adoption of SFAS No. 133 during the quarter ended March 31, 2001; and

     - Increased volatility in future earnings is possible due to the impact of
       market fluctuations on derivative instruments used by NRG Energy.

     In September 2000, the FASB issued Statement No. 140, Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities -- A Replacement of FASB Statement No. 125 (SFAS

                                        47
<PAGE>   50

No. 140). SFAS No. 140 revises the standards for accounting for securizations
and other transfers of financial assets and collateral and requires certain
disclosures, but it carries over most of SFAS No. 125's provisions without
reconsideration. SFAS No. 140 is effective for NRG Energy's fiscal year ending
December 31, 2001. The adoption of SFAS No. 140 is not expected to have a
significant impact on NRG Energy's consolidated financial position or results of
operations.

RECLASSIFICATIONS

     Certain prior-year amounts have been reclassified for comparative purposes.
These reclassifications had no effect on net income or total stockholders'
equity as previously reported.

NOTE 3 -- ASSET ACQUISITIONS AND DIVESTITURES

     In March 2000, NRG Energy acquired the assets of the Killingholme A
generation facility from National Power plc for (pound)390 million
(approximately $615 million at the time of acquisition), subject to post-
closing adjustments. Killingholme is a combined cycle gas-fired baseload
facility located in North Lincolnshire, England. The facility comprises three
units with a total generating capacity of 680 megawatts (MW). NRG Energy owns
and operates the facility, which sells power into the wholesale electricity
market of England and Wales.

     In March 2000, NRG Energy acquired 1,708 MW of coal and gas-fired
generation assets in Louisiana for approximately $1,055.9 million (the Cajun
facilities). These assets were formally owned by Cajun Electric Power
Cooperative, Inc. (Cajun Electric). NRG Energy sells a significant amount of the
energy and capacity of the Cajun facilities to 11 of Cajun Electric's former
power cooperative members. Seven of these cooperatives have entered into 25-year
power purchase agreements with NRG Energy, and four have entered into two to
four year power purchase agreements. In addition, NRG Energy sells power under
contract to two municipal power authorities and one investor-owned utility that
were former customers of Cajun Electric. See Note 21 for unaudited pro forma
results of operations as if the acquisition of the Cajun facilities had occurred
at the beginning of the periods disclosed.

     In September 2000, NRG Energy completed the acquisition of Flinders Power
in South Australia. NRG Energy paid approximately AUD $314.4 million (U.S.$180
million as of the date of the acquisition) for a 100-year lease of the Flinders
Power assets. Flinders Power includes two power stations totaling 760 MW: the
Leigh Creek coal mine and a dedicated rail line. The lease agreement also
includes managing the long-term fuel supply and power purchase agreement of the
180 MW Osborne Cogeneration Station.

NOTE 6 -- INVESTMENTS ACCOUNTED FOR BY THE EQUITY METHOD

     NRG Energy has investments in various international and domestic energy
projects. The equity method of accounting is applied to such investments in
affiliates, which include joint ventures and partnerships, because the ownership
structure prevents NRG Energy from exercising a controlling influence over
operating and financial policies of the projects. Under this method, equity in
pretax income or losses of domestic partnerships and, generally, in the net
income or losses of international projects are reflected as equity in earnings
of unconsolidated affiliates.

     A summary of NRG Energy's significant equity-method investments which were
in operation at December 31, 2000 is as follows:

     In accordance with SFAS No. 121, NRG Energy reviews long lived assets,
investments and certain intangibles for impairment whenever events or
circumstances indicate the carrying amounts of an asset may not be recoverable.
During 1998, NRG Energy wrote down accumulated project development expenditures
of $26.7 million. NRG Energy's West Java, Indonesia, project totaling $22.0
million was written off due to the uncertainties surrounding infrastructure
projects in Indonesia. Also during 1998, NRG Energy wrote off its $1.9 million
investment in the Sunnyside project and its $2.8 million investment in Alto
Cachopoal. The charge represents the difference between the carrying amount of
the investment and the fair value of the asset, determined using a cash flow
model.

facilities under a commitment fee arrangement. These facilities provide
short-term financing in the form of bank loans and letters of credit. At

     NRG Energy had $63.0 million and $116.0 million in outstanding letters of
credit as of December 31, 2000 and 1999, respectively.

assets of the Minneapolis Energy Center (MEC). In accordance with the terms of
the note agreement, MEC is required to maintain compliance with certain
financial covenants primarily related to incurring debt, disposing of MEC
assets, and affiliate transactions. MEC was in compliance with these covenants
at December 31, 2000.

     The NRG Energy $125 million, $250 million, $300 million, $240 million and
$350 million senior notes are unsecured and are used to support equity
requirements for projects acquired and in development. The interest is generally
paid semi-annually.

     The $240 million NRG Energy Senior notes due November 1, 2013 are
remarketable or redeemable Security (ROARS). November 1, 2003 is the first
remarketing date for these notes. Interest is payable semi-annually on May 1,
and November 1, of each year through 2003, and then at intervals and interest
rates as discussed in the indenture. On the remarketing date, the notes will
either be mandatorily tendered to and purchased by Credit Suisse Financial
Products or mandatorily redeemed by NRG Energy at prices discussed in the
indenture. The notes are unsecured debt that rank senior to all of NRG Energy's
existing and future subordinated indebtedness.

     The various NEO notes are term loans. The loans are secured principally by
long-term assets of NEO Landfill Gas collection system. NEO Landfill Gas is
required to maintain compliance with certain covenants primarily related to
incurring debt, disposing of the NEO Landfill Gas assets, and affiliate
transactions. NEO was in compliance with these covenants at December 31, 2000.

     On February 22, 2000, NRG Northeast Generating LLC, an indirect,
wholly-owned subsidiary of NRG Energy issued $750 million of project level
senior secured bonds, to refinance short-term project borrowings and for certain
other purposes. The bond offering included three tranches: $320 million with an
interest rate of 8.065% due in 2004, $130 million with an interest rate of
8.842% due in 2015 and $300 million with an interest rate of 9.292% due in 2024.
The bonds are jointly and severally guaranteed by each of NRG Northeast's
existing and future subsidiaries. The bonds are secured by a security interest
in NRG Northeast's membership or other ownership interests in the guarantors and
its rights under all intercompany notes between NRG Northeast and the
guarantors. Approximately $646.6 million of the proceeds from these bonds were
used to repay short-term borrowings outstanding at December 31, 1999;
accordingly, $646.6 million of short-term debt was re-classified as long-term
debt, based on this refinancing. In December, 2000, NRG Northeast Generating LLC
exchanged all of its outstanding bonds for bonds registered under the Securities
Act of 1933. As of December 31, 2000, there remains $700 million of outstanding
bonds.

     In March 2000, NRG Energy issued $250 million of 8.70% ROARS due March 15,
2005. Each security represents a fractional interest in the assets of an
unconsolidated grantor trust that pays interest semi-annually on March 15, and
September 15, of each year through 2005. The sole assets of the Trust consists
of (pound)160 million of Reset senior notes due March 15, 2020 issued by NRG
Energy pursuant to the Indenture and certain other defined rights. The Reset
senior notes were used principally to finance NRG Energy's acquisition of the
Killingholme facility. On March 15, 2005, these senior notes may be remarketed
by Bank of America, N.A. at a fixed rate of interest through the maturity date
or, at a floating rate of interest for up to one year and then at a fixed rate
of interest through 2020. Interest is payable semi-annually on these securities
beginning September 15, 2000 through March 15, 2005, and then at intervals and
interest rates established in the remarketing process.

     Additionally, three of NRG Energy's foreign subsidiaries entered into a
(pounds) 325 million (US $517 million at March 31, 2000) secured borrowing
facility agreement with Bank of America International Limited. Under this
facility, the financial institutions have made available to our subsidiaries
various term loans totaling (pounds)235 million (US $374 million at March 31,

(pounds)90 million (US $143 million at March 31, 2000) of revolving credit and
letter of credit facilities to provide working capital for operating the

largest tranche of the term facility have been repaid or cancelled.

     In March 2000, NRG South Central Generating LLC, an indirect wholly-owned

interests in NRG South Central and NRG South Central's membership interests in
Louisiana Generating and all of the assets related to the Cajun facilities
including its rights under a guarantor loan agreement and all intercompany notes

purposes, which includes financing, development and construction of new
facilities, additions to working capital and financing capital expenditures and
pending or potential acquisitions. The remaining $150 million was combined with

issue up to $1,650.0 million of an indeterminate amount of debt securities,

NOTE 10 -- INCOME TAXES

     NRG Energy and its parent, Xcel, have entered into a federal and state
income tax sharing agreement relative to the filing of consolidated federal and
state income tax returns. The agreement provides, among other things, that (1)
if NRG Energy, along with its subsidiaries, is in a taxable income position, NRG
Energy will be currently charged with an amount equivalent to its federal and
state income tax computed as if the group had actually filed separate federal
and state returns, and (2) if NRG Energy, along with its subsidiaries, is in a
tax loss position, NRG Energy will be currently reimbursed to the extent its
combined losses are utilized in a consolidated return, and (3) if NRG Energy,
along with its subsidiaries, generates tax credits, NRG Energy will be currently
reimbursed to the extent its tax credits are utilized in a consolidated return.

     The effective income tax rate for 2000 differs from the statutory federal
income tax rate of 35% as follows:

                                                   ========    ========
</TABLE>

     For the year ended December 31, 2000, income tax expense was $92.7 million,
compared to an income tax benefit of $26.1 million for the year ended December
31, 1999, an increase of $118.8 million. The increase in tax expense compared to
1999 is due primarily to higher domestic taxable income. This increase was
partially offset by additional IRC Section 29 energy tax credits. For the year
ended December 31, 2000, NRG Energy's overall effective income tax rate was
approximately 34%. NRG Energy's effective income tax rate before recognition of
tax credits was approximately 46%. This rate is higher than a combined federal
and Minnesota statutory rate because a significant portion of NRG Energy's
income is generated in New York City, an area with high state and local tax
rates. In addition, NRG Energy has recorded a valuation allowance on certain
state and foreign tax losses, also increasing the effective tax rate.

     The effective income tax rate for the years 1999 and 1998 differs from the
statutory federal income tax rate of 35% primarily due to state tax, foreign tax
and tax credits as shown above. Income and expenses from foreign operations are
not subject to U.S. taxes (as discussed below).

     NRG Energy intends to reinvest the earnings of foreign operations except to
the extent the earnings are subject to current U.S. income taxes. Accordingly,
U.S. income taxes and foreign withholding taxes have not been provided on a
cumulative amount of unremitted earnings of foreign subsidiaries of
approximately $232 million and $195 million at December 31, 2000 and 1999. The
additional U.S. income tax and foreign withholding tax on the unremitted foreign
earnings, if repatriated, would be offset in whole or in part by foreign tax
credits. Thus, it is not practicable to estimate the amount of tax that might be
payable.

NOTE 11 -- BENEFIT PLANS AND OTHER POSTRETIREMENT BENEFITS PENSION BENEFITS

PENSION BENEFITS

     NRG Energy participates in the portion of Xcel's noncontributory, defined
benefit pension plan which was formerly administered by NSP, and covers
substantially all of NRG's employees. Benefits are based on a combination of
years of service, and in most cases the employee's highest average pay. Some
formulas also take into account Social Security benefits. During 2000, the
pension benefits attributable to NRG Energy's 1999 acquisitions were combined
with Xcel's plan. Plan assets principally consist of the common stock of public
companies, corporate bonds and U.S. government securities. NRG Energy's net
annual periodic pension cost includes the following components:

     The weighted average discount rate used in determining the actuarial
present value of the projected benefit obligation was 7.75% for December 31,
2000 and 1999. The rate of increase in future compensation levels used in
determining the actuarial present value of the projected obligation was 4.5% in
2000 and 1999. The assumed long-term rate of return on assets used for cost
determinations was 8.5% for 2000 and 1999.

     NRG Energy participates in Xcel's defined contribution 401(K) savings plan,
as well as sponsoring several of its own defined contribution savings plans as a
result of its 1999 and 2000 acquisition activity. Substantially all employees
are covered by one of these plans. Total contributions to the plan were
approximately $2.2 million, $0.5 million and $0.2 million for the years ended
December 31, 2000, 1999 and 1998, respectively.

NRG EQUITY PLAN

     During 1998 and 1999, NRG Energy's employees were eligible to participate
in its Equity Plan (the Plan). The Plan granted, to employees, phantom equity
units that were intended to simulate Stock options. Grant size was based on the
participant's position in the Company and base salary. Equity unit valuations
were performed annually by an outside valuation firm. The value of an equity
unit was the approximate value per share of NRG Energy's stockholder equity as
of the valuation date, less the value of Xcel's (formerly NSP) equity
investments. The units were awarded to employees annually at the respective
year's calculated share price (grant price). The Plan provided employees with a
cash pay out for the unit's appreciation in value over the vesting period. The
Plan had a seven year vesting schedule with actual payments beginning after the
end of the third year and continuing at 20% each year for the subsequent five
years. During 2000, 1999 and 1998, NRG Energy recorded compensation expense of
approximately $6.0 million, $13.0 million and $2.6 million, respectively, for
the Plan.

     The Plan included a change of control provision, which allowed all shares
to vest if NRG Energy's ownership were to change. Subsequent to the completion
of NRG Energy's initial public offering in June 2000, the Plan was converted to
a new stock option plan; see Note 14.

POSTRETIREMENT HEALTH CARE

     NRG Energy participates in Xcel's contributory health and welfare benefit
plan which was formerly administered by NSP, and provides health care and death
benefits to substantially all NRG Energy retirees. The legacy Xcel plan was
terminated for nonbargaining employees retiring after 1998 and for bargaining
employees retiring after 1999. For covered retirees, the plan enables NRG Energy
to share the cost of retiree health costs. Cost-sharing for bargaining employees
is governed by the terms of the collective bargaining agreement.

     NRG Energy also provides postretirement health and welfare benefits for
substantially all of its employees associated with the 1999 acquisition
activity. The plan administered by NRG Energy provides eligible retirees with
both health care and death benefits. Cost sharing varies by acquisition group
and the terms of the collective bargaining agreements. The cost of these
benefits was reported in the Xcel plan costs in 2000.

     Postretirement health care benefits for NRG Energy are determined and
recorded under the provisions of SFAS No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions." SFAS No. 106

                                        57

requires the actuarially determined obligation for postretirement health care
and death benefits to be fully accrued by the date employees attain full
eligibility for such benefits, which is generally when they reach retirement
age.

     The assumed health care cost trend rates used in measuring the accumulated

8.1% for those under age 65, and 6.1 % for those over age

                                        58

65. The assumed cost trends are expected to decrease each year until they reach
5.5% for both age groups in the year 2004, after which they are assumed to
remain constant. A one percent increase in the assumed health care cost trend
rate would increase the APBO by approximately $1.8 million as of December 31,
2000. Service and interest cost components of the net periodic postretirement
cost would increase by approximately $230,000 with a similar one percent
increase in the assumed health care cost trend rate. A one percent decrease in
the assumed health care cost trend rate would decrease the APBO by approximately
$1.4 million as of December 31, 2000. Service and interest cost components of
the net periodic post retirement cost would decrease by approximately $175,000
with a similar one percent decrease in the assumed health care cost trend rate.
The assumed discount rate used in determining the APBO was 7.75% for both
December 31, 2000 and 1999, compounded annually. The assumed long-term rate of
return on assets used for cost determinations under SFAS No. 106 was 8% for
2000, 1999 and 1998.

PENSION AND OTHER BENEFITS -- 1999 ACQUISITIONS

     During 1999, NRG Energy acquired several generating assets and assumed
benefit obligations for a number of employees associated with those
acquisitions. The plans assumed included noncontributory defined benefit pension
formulas, matched 401(k) savings plans, and contributory post-retirement welfare
plans. Of the 1999 acquisitions where these obligations were assumed
approximately 66 percent of such employees are represented by seven local labor
unions under collective bargaining agreements, which expire between 2001 and
2003.

     For these employees, NRG Energy sponsored one noncontributory, defined
benefit pension plan that covered most of the employees associated with the 1999
acquisitions. Generally, the benefits are based on a combination of years of
service and in most cases the employee's highest average pay. Some formulas also
take into account Social Security benefits. During the year 2000, the pension
benefit attributable to NRG Energy's 1999 acquisitions were combined with Xcel's
plan. The pension formulas remained unchanged.

employees and 3.50% for union employees. The assumed long-term rate of return on
assets used for cost determinations was 8.5% for 1999.

POSTRETIREMENT HEALTH CARE

     NRG Energy has also assumed post retirement health care benefits for some
of its employees associated with the 1999 acquisitions. The plan enables NRG
Energy and the retirees to share the costs of retiree health care. The cost
sharing varies by acquisition group and collective bargaining agreements. There
are no existing retirees under these plans as of December 31, 1999. The
estimated net periodic postretirement benefit cost for 1999 is $0.85 million.
The estimated accumulated post-retirement benefit obligation is $16 million at
December 31, 1999.

     During the year 2000, the postretirement health care benefit obligations
attributable to NRG Energy's 1999 acquisitions were combined with Xcel's plan.

401(K) PLANS

     NRG Energy also assumed several contributory, defined contribution employee
savings plans as a result of its 1999 acquisition activity. These plans comply
with Section 401(k) of the Internal Revenue Code and

million in 1999, respectively.

PENSION AND OTHER BENEFITS -- 2000 ACQUISITIONS

Flinders Power, South Australia

     Flinders Power participates with other companies in the electric generation
industry in South Australia, in making payments to pension funds, which are not
administered by Flinders Power. Pension costs relating to multi-employer plans
were approximately $1.3 million for the period ended August 3, 2000 (date of
acquisition), to December 31, 2000.

NOTE 12 -- SALES TO SIGNIFICANT CUSTOMERS

     During 2000, sales to two customers accounted for 22.2% and 12.2% of total
revenues from majority owned operations in 2000. Sales to three customers
accounted for 21.0%, 19.7% and 10.5% of total revenues from wholly owned
operations in 1999.

     NRG Energy and the Ramsey/Washington Resource Recovery Project have a
service agreement for waste disposal, which expires in 2006. In 1998,
approximately 26.5% of NRG Energy's operating revenues were recognized under
this contract. In addition, sales to one thermal customer amounted to 10.3% of
operating revenues in 1998.

     For cash and cash equivalents and restricted cash, the carrying amount
approximates fair value because of the short-term maturity of those instruments.
The fair value of notes receivable is based on expected future cash flows
discounted at market interest rates. The fair value of long-term debt is
estimated based on the quoted market prices for the same or similar issues.

DERIVATIVE FINANCIAL INSTRUMENTS

Foreign currency exchange rates

     In the third quarter of 2000, NRG Energy entered into a contract with a
notional amount of approximately $8.8 million to hedge or protect foreign
currency denominated cash flows. This foreign currency exchange instrument was a
hedge of a Killingholme project distribution and expired in January 2001. If
this hedge had been discontinued on December 31, 2000, NRG Energy would have
owed the counterparty approximately $700,000.

Interest rates

     As of December 31, 2000, NRG Energy has four interest rate swap agreements
with notional amounts totaling approximately $530 million. The contracts are
used to manage NRG Energy's exposure to changes in interest rates. If the swaps
had been discontinued on December 31, 2000, NRG Energy would have owed the
counterparties approximately $28.9 million.

                                        61
<PAGE>   64

Energy and energy related commodities

     As discussed in Note 2, NRG Energy is exposed to commodity price
variability in electricity, emission allowances and natural gas, oil and coal
used to meet fuel requirements. In order to manage these commodity price risks,
NRG Energy enters into financial instruments, which may take the form of fixed
price, floating price or indexed sales or purchases, and options, such as puts,
calls, basis transactions and swaps. At December 31, 2000 and 1999, the net
notional amount of such transactions was approximately $309 million and $207
million. If these contracts were terminated at December 31, 2000 and 1999, the
Company would have received approximately $52.8 and $12 million based on price
fluctuations to date.

CREDIT RISK

     Management believes that NRG Energy's exposure to credit risk due to
nonperformance by the counterparties to its hedging contracts is insignificant,
based on the investment grade rating of the counterparties. Counterparties
consist principally of financial institutions and major energy companies.

NOTE 14 -- CAPITAL STOCK

SALE OF STOCK

     In June 2000, NRG Energy sold 32.4 million shares of common stock at $15.00
per share. Net proceeds from the offering were $453.7 million. NRG Energy has
authorized capital stock consisting of 550,000,000 shares of common stock, and
250,000,000 shares of Class A common stock. At December 31, 2000, there were
approximately 32,396,000 shares of common stock, and 147,605,000 shares of Class
A common stock issued and outstanding.

INCENTIVE COMPENSATION PLAN

     In June 2000, NRG Energy adopted a new incentive compensation plan (the New
Stock Plan), which will be administered by the Board of Directors, or a
committee appointed by the Board of Directors. The New Stock Plan provides for
awards in the form of stock options, stock appreciation rights, restricted
stock, performance units, performance shares, or cash based awards as determined
by the Board of Directors. All officers, certain other employees, and
non-employee directors are eligible to participate in the plan. Nine million
shares of common stock are authorized for issuance under the Stock Plan.
Initially, only stock option grants will be made to certain officers and
employees under the plan.

STOCK OPTIONS

     Each new option granted is valued at the fair market value per share at
date of grant. The difference between the option price and the fair market
value, if any, of each option on the date of grant is recorded as compensation
expense over a vesting period. Options granted vest over a period of five years,
with 25% vesting in each of the years two through five and generally expire ten
years from the date of grant. The average exercise price of vested options at
December 31, 2000 was $9.51 all of which were granted in replacement of units
previously outstanding under the equity plan. Compensation expense related to
options granted totaled $7.2 million, for the year ended December 31, 2000.

                                        62
<PAGE>   65

     At December 31, 2000, no employee stock options were exercisable. Other
options currently granted under the equity plan will fully vest periodically and
become exercisable through the year 2005 at prices ranging from $5.75 to $17.25.

NOTE 15 -- EARNINGS PER SHARE

     Basic earnings per common share were computed by dividing net income by the
weighted average number of common shares outstanding for the period. The
dilutive effect of the potential exercise of outstanding options to purchase
shares of common stock is calculated using the treasury stock method. NRG
Energy's only common equivalent shares are those that result from dilutive
common stock options. The reconciliation of basic earnings per common share to
diluted earnings per share is shown in the following table (in thousands, except

CAPITAL COMMITMENTS

     NRG Energy's management expects future capital expenditures related to
projects listed below, as well as construction and the purchase of turbines, to
total approximately $6,500 million in the years 2001 through 2005. NRG Energy
anticipates funding its ongoing capital requirements through the issuance of
debt, equity and equity like instruments, preferred stock and operating cash
flows.

     NRG Energy has contractually agreed to the monetization of certain tax
credits generated from landfill gas sales through the year 2007.

     In 1999, NRG Energy and its partners were selected as winning bidder to
enter into a 20-year lease of the 600 MW Seyitomer Power Station and related
lignite mine located in Kuthya, Turkey. In 1998, also with partners, NRG Energy
won a bid to enter into a 20-year lease of the 457 MW coal-fired Kangal plant in
central Turkey. A law has been introduced in the Turkish parliament that would
require these projects, among others, to close by June 30, 2001 or be cancelled,
and NRG Energy is working to meet this deadline.

     In January 2000, NRG Energy executed purchase agreements with subsidiaries
of Conectiv to acquire 1,875 MW of coal, gas and oil-fired electric generating
capacity and other assets in New Jersey, Delaware, Maryland and Pennsylvania.
NRG Energy will pay approximately $800 million for the assets. NRG Energy
expects the acquisition to close in the second quarter of 2001.

     In August 2000, NRG Energy signed a Heads of Terms Agreement with Eesti
Energia, the Estonian state-owned electric utility, providing for the purchase
for approximately $65.5 million of a 49% stake in Narva Power, the owner and
operator of the oil shale-fired Eesti and Balti power plants, located near
Narva, Estonia. The plants have a combined capacity of approximately 2,700 MW.
NRG Energy expects the acquisition to close in the second quarter of 2001.

     In October 2000, NRG Energy signed an asset purchase agreement to acquire
from Sierra Pacific Resources its 50% interest in the 522 MW coal-fired North
Valmy Station located in Valmy, Nevada, and a 100% interest in 25 MW of peaking
units near the North Valmy Station, for a purchase price of approximately $273
million. Idaho Power, the other 50% owner of the North Valmy Station, has a
180-day right of first refusal to purchase this 50%. The right of first refusal
expires in May 2001. In addition, the California legislature recently enacted
legislation prohibiting any public utility from selling any generation asset
until 2006. This law applies to Sierra Pacific Resources because approximately
10% of its ratepayers are located in California. NRG Energy is working to have
legislation introduced to exempt the North Valmy Station and the peaking units
from the application of this law.

     In November 2000, NRG Energy agreed to form a partnership with Avista-STEAG
LLC to build, operate and manage a 633 MW natural gas-fired power plant in Fort
Bend County, Texas. NRG Energy expects to own 50% of the project. NRG Energy
estimates that its investment in the project will total approximately $163
million. Construction of the plant is expected to begin in early 2001, with
commercial operation expected in February 2003.

                                        65
<PAGE>   68

     In November 2000, NRG Energy in conjunction with its partner Dynegy Inc.,
executed asset purchase agreements to acquire the 740 MW gas-fired Clark Station
and 445 MW of the 605 MW coal-fired Reid Gardner Station, both located near Las
Vegas, Nevada. The purchase price is approximately $634 million. NRG Energy
expects to close the acquisition during the second quarter of 2001. In addition,
NRG Energy and Dynegy are negotiating to acquire an additional 145 MW of the
Reid Gardner Station.

     In December 2000, NRG Energy signed asset purchase agreements to acquire
the 585 MW coal-fired Bridgeport Harbor Station and the 466 MW oil and gas-fired
New Haven Harbor Station in Connecticut for approximately $325 million. NRG
Energy expects the acquisition to close during the second quarter of 2001.

     In December 2000, NRG Energy and its partner, Dynegy Inc., submitted permit
applications in respect of a planned repowering of our jointly-owned El Segundo
Station in El Segundo, California. The planned repowering would add
approximately 621 MW of generating capacity to the facility at a cost of
approximately $368 million. Prior to the repowering, approximately 350 MW at the
El Segundo Station will be decommissioned. The repowering project has a targeted
operation date of June 2003.

     In December 2000, NRG Energy signed a purchase agreement to acquire a 540
MW natural gas-fired generation facility being developed in Meriden,
Connecticut, for a purchase price of approximately $25 million. NRG Energy
expects to close the acquisition in the first quarter of 2001. NRG Energy
estimates costs of approximately $384 million to complete construction of the
plant, which has a planned commercial operation date of June 2003.

CONTINGENT REVENUES

Regulatory Issue

     On March 30, 2000, NRG Energy received notification from the New York
Independent System Operator (NYISO) of its petition to the Federal Energy
Regulatory Commission (FERC) to place a $2.52 per megawatt hour market cap on
ancillary service revenues. The NYISO also requested authority to impose this
cap on a retroactive basis to March 1, 2000.

     On May 31, 2000, the FERC approved the NYISO's request to impose price
limitations on one ancillary service, Ten Minute Non-Synchronized Reserves
(TMNSR) on a prospective basis only, effective March 28, 2000. The FERC rejected
the NYISO's request for authority to adjust the market-clearing prices for TMNSR
on a retroactive basis. As a result of the FERC order, (unless the NYISO or
other party successfully appeals the order), NRG Energy will retain
approximately $8.0 million of revenues collected in February 2000. NRG Energy
has included in revenues, but has not yet collected for March 2000,
approximately $8.2 million, which has been fully reserved for as of December 31,
2000.

Disputed Revenues

     As of December 31, 2000, NRG Energy had disputed revenues totaling $13.1
million relating to the interpretation of certain transmission power sales
agreements and to sales to the New York Power Pool and New England Power Pool,
conflicting meter readings, pricing of firm sales and other power pool reporting
issues. NRG Energy is actively pursuing resolution and/or collection of these
amounts. These amounts have not been recorded in the financial statements and
will not be recognized as income until disputes are resolved and collection is
assured.

     As of December 31, 2000, NRG Energy's portion of disputed revenues of its
California affiliates totaled $17.4 million. These amounts relate to disputes
arising in the ordinary course of business and to disputes that have arisen as a
result of the California ISO imposing various revenue caps on the wholesale
price of electricity. These amounts have not been recorded in the financial
statements and will not be recognized as income until disputes are resolved and
collection is assured.

<PAGE>   69

California Liquidity Crisis

     NRG Energy owns approximately 1,569 MW of net generating capacity in
California, which represented approximately 11% of its net MW of operating
projects and projects under construction as of December 31, 2000.

     NRG Energy's California generation assets consist primarily of interests in
the Crockett and Mt. Poso facilities and a 50% interest in West Coast Power LLC,
formed in 1999 with Dynegy, Inc. Through the California Power Exchange (PX) and
the California Independent System Operator (ISO), the West Coast Power
facilities sell power to Pacific Gas and Electric Company (PG&E), Southern
California Edison Company (SCE) and San Diego Gas and Electric Company (SDG&E),
the three major California investor owned utilities. Crockett, Mt. Poso, and
certain of NRG Energy's other California facilities also sell directly to PG&E,
SCE and SDG&E. The liquidity crisis faced by both PG&E and SCE, as a result of
tight electricity supplies, rising wholesale electric prices and caps on the
rates that PG&E and SCE may charge their retail customers, has caused both PG&E
and SCE to partially suspend payments to the California PX and the California
ISO.

     NRG Energy's share of the accounts receivable owed to its California
operations by the California PX, the California ISO and the three major
California utilities totaled approximately $105 million as of December 31, 2000.
NRG Energy believes that the amounts that have been recorded as accounts
receivable will ultimately be collected in full; however, if some form of
financial relief or support is not provided to PG&E and SCE, the collectibility
of these receivables will become more questionable in terms of both timing and
amount.

CONTRACTUAL COMMITMENTS

     In connection with the recent acquisition of certain generating facilities
NRG Energy has entered into various long-term transition agreements and standard
offer agreements that obligated NRG Energy to provide its customers, primarily
the previous owners of the acquired facilities, with a certain portion of the
energy and capacity output of the acquired facilities.

     During 1999, NRG Energy acquired the Huntley and Dunkirk generating
facilities from Niagara Mohawk Power Corporation (NiMo). In connection with this
acquisition, NRG Energy entered into a 4-year agreement with NiMo that requires
NRG Energy to provide to NiMo pursuant to a predetermined schedule fixed
quantities of energy and capacity at a fixed price.

     During 1999, NRG Energy acquired certain generating facilities from
Connecticut Light and Power Company (CL&P). NRG also entered into a 4-year
standard offer agreement that requires NRG Energy to provide to CL&P a portion
of its load requirements through the year 2003 at a substantially fixed rate.

     During 2000, NRG Energy acquired the non-nuclear generating assets of Cajun
Electric. Upon acquisition of the facilities, NRG Energy entered into various
long-term power purchase agreements with the former customers of Cajun Electric,
primarily distribution cooperatives and municipalities. These agreements specify
that NRG Energy provide these customers with all requirements necessary to
satisfy the energy and capacity needs of their retail load.

     Also during 2000, NRG Energy acquired the Killingholme generating
facilities from National Power plc. In connection with this acquisition, NRG
Energy entered into certain agreements to provide the natural gas to operate the
facility which generally sells its power into the spot market. NRG Energy has
entered into two gas purchase agreements, the first being a 5-year agreement
that provides approximately 30% of the generating facilities natural gas
requirements and the second agreement being a 10-year agreement that provides
approximately 70% of the generating facilities natural gas requirements. NRG
Energy has also entered into a 5-year fixed price agreement to resell up to 15%
of the gas it has contracted for at a slightly higher price.

     Also during 2000, NRG Energy acquired the Flinders Power operations in
South Australia. Upon the closing of the acquisition, NRG Energy assumed a gas
purchase and sales agreement relating to the Osborne generating plant with a
remaining life of 18-years. These agreements require NRG Energy to purchase a

                                        67
<PAGE>   70

specified quantity of natural gas from a third party supplier at a fixed price
for 18-years and resell the natural gas to Osborne at a fixed price for
13-years. The sales price is substantially lower than the purchase price. NRG
Energy has recorded the loss associated with this out of the market contract on
its balance sheet. In addition, NRG Energy has entered into a contract for
differences agreement which provides for the sale of energy into the South
Australian power pool through the year 2002. The agreement provides for a swap
of the variable market price to a fixed price.

ENVIRONMENTAL REGULATIONS

     NRG Energy, like most industrial enterprises, is subject to regulation with
respect to the environmental impact of its operations, including air, water and
land, limitations on land use, disposal of waste, aesthetics and other matters.

     Environmental laws and/or regulations derived therefrom generally require
air emissions and water discharges to meet specified limits. They also impose
potential joint and several liability, with regard to fault, on entities
responsible for certain releases of hazardous substances to manage such
materials properly and to clean up property affected by their production and
discharge. NRG Energy expects to spend approximately $60 million for capital
expenditures between 2001 and 2005 for environmental compliance, which includes
the possible installation of Nitrogen oxides (NOx) control technology at the
Somerset facility, resolution of consent orders for remediation at the Arthur
Kill and Astoria facilities, the resolution of a consent order for water intake
at the Arthur Kill facility, and completing remediation-related requirements
under the Connecticut Transfer Act. During the years 2000, 1999 and 1998, NRG
Energy recorded approximately $3.4 million, $0.3 million and $0 of expenditures
related to environmental matters.

     In response to liabilities associated with these activities, accruals have
been established when reasonable estimates are possible. As of December 31,
2000, NRG Energy has established such accruals in the amount of approximately
$6.0 million. Such accruals primarily include estimated costs associated with
remediation. NRG Energy has not used discounting in determining its accrued
liabilities for environmental remediation and no claims for possible recovery
from third party issuers or other parties related to environmental costs have
been recognized in NRG Energy's consolidated financial statements. NRG Energy
adjusts the accruals when new remediation responsibilities are discovered and
probable costs become estimatable, or when current remediation estimates are
adjusted to reflect new information.

NOTE 18 -- SEGMENT REPORTING

     NRG Energy conducts its business within six segments: Independent Power
Generation in North America, Independent Power Generation outside North America
(Europe, Asia Pacific and Other Americas regions), Alternative Energy and
Thermal projects. NRG Energy's Revenues from wholly owned operations
attributable to Europe and Asia Pacific primarily relate to operations in the
United Kingdom and Australia, respectively. These segments are distinct
components with separate operating results and management structures in place.
The "Other" category includes operations that do not meet the threshold for
separate

                                        68
<PAGE>   71

disclosure and corporate charges (primarily interest expense) that have not been
allocated to the operating segments.

NOTE 19 -- JOINTLY OWNED PLANT

     On March 31, 2000, NRG Energy acquired a 58% interest in the Big Cajun II,
Unit 3 generation plant. Entergy Gulf States owns the remaining 42%. Big Cajun
II, Unit 3 is operated and maintained by Louisiana Generating pursuant to a
joint ownership participation and operating agreement. Under this agreement,
Louisiana Generating and Entergy Gulf States are each entitled to their
ownership percentage of the hourly net electrical output of Big Cajun II, Unit
3. All fixed costs are shared in proportion to the ownership interests. Fixed
costs include the cost of operating common facilities. All variable costs are
incurred in proportion to the energy delivered to the owners. NRG Energy's
income statement includes our share of all fixed and variable costs of operating
the unit. NRG Energy's 58% share of the original cost included in Plant,
Property and Equipment at December 31, 2000 was $179.1 million. The
corresponding accumulated depreciation and amortization was $3.4 million.

NOTE 20 -- DECOMMISSIONING FUNDS

     NRG Energy is required by the State of Louisiana Department of
Environmental Quality ("DEQ") to rehabilitate NRG Energy's Big Cajun II ash and
wastewater impoundment areas, subsequent to the Big Cajun II facilities' removal
from service. On July 1, 1989, a guarantor trust fund (the "Solid Waste Disposal
Trust Fund") was established to accumulate the estimated funds necessary for
such purpose. NRG Energy's predecessor deposited $1.06 million in the Solid
Waste Disposal Trust Fund in 1989, and funded $116,000 annually thereafter,
based upon an estimated future rehabilitation cost (in 1989 dollars) of
approximately $3.5 million and the remaining estimated useful life of the Big
Cajun II facilities. Cumulative contributions to the Solid Waste Disposal Trust
Fund and earnings on the investments therein are accrued as a decommissioning

                                        70

liability. At December 31, 2000, the carrying value of the trust fund
investments and the related accrued decommissioning liability was approximately
$3.9 million. The trust fund investments are comprised of various debt
securities of the United States and are carried at amortized cost, which
approximates their fair value.

NOTE 21 -- UNAUDITED PRO FORMA RESULTS OF OPERATIONS -- CAJUN ACQUISITION

     During March 2000, NRG Energy completed its acquisition of two fossil
fueled generating plants from Cajun Electric Power Cooperative, Inc. for
approximately $1,056 million. The following information summarizes the unaudited
pro forma results of operations as if the acquisition had occurred as of the
beginning of the twelve-month period ended December 31, 2000 and 1999. The
unaudited pro forma information presented is for informational purposes only and
is not necessarily indicative of future earnings or financial position or of
what the earnings and financial position would have been had the acquisition of
the Cajun facilities been consummated at the beginning of the respective periods

NOTE 22 -- SUBSEQUENT EVENTS

LS Power Acquisition

     In January 2001, NRG Energy completed the acquisition of a 5,691 MW
portfolio of operating projects and projects in construction and advanced
development from LS Power, LLC for $708 million, subject to purchase price
adjustments. Additionally, until December 31, 2005, NRG Energy has the
opportunity to acquire ownership interests in the next 3,000 MW of generation
projects developed and offered for sale by LS Power and its partners. This
acquisition was initially financed in part by a $600 million bridge credit
agreement which has a maturity date of December 31, 2001. At January 31, 2001,
the weighted average interest rate was 6.425%.

California Liquidity Crisis

     With respect to the liquidity crisis in California discussed in Note 17,
various legislative, regulatory and legal remedies to the liquidity crisis faced
by PG&E and SCE have been implemented or are being pursued. Assembly Bill 1X,
which authorizes the California Department of Water Resources to enter into
contracts for the purchase of electric power through January 1, 2003 and to
issue revenue bonds to fund such purchases, was signed into law by the Governor
of California on February 1, 2001. Assembly Bill 18X, which provides a

                                        71
<PAGE>   74

framework for the recovery of PG&E and SCE's uncollected expenses for purchasing
power for delivery to their retail customers, is currently under consideration
in the California legislature.

     The delayed collection of receivables owed to West Coast Power resulted in
a covenant default under its credit agreement. West Coast Power is working with
its lenders to secure their agreement to forebear exercising their remedies
under the credit agreement.

         364-DAY REVOLVING CREDIT AGREEMENT, dated as of March 9, 2001 among NRG
Energy, Inc., a Delaware corporation (the "Borrower"), the financial
institutions from time to time party hereto (each a "Bank," and collectively the
"Banks") and ABN AMRO Bank N.V. in its capacity as agent for the Banks hereunder
(in such capacity, the "Agent").

                                WITNESSETH THAT:

         WHEREAS, the Borrower desires to obtain the several commitments of the
Banks to make available a revolving credit for loans (the "Revolving Credit"),
as described herein; and

         WHEREAS, the Banks are willing to extend such commitments subject to
all of the terms and conditions hereof and on the basis of the representations
and warranties hereinafter set forth;

         NOW, THEREFORE, in consideration of the recitals set forth above and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1.    DEFINITIONS; INTERPRETATION.

Section 1.1   Definitions.  The following terms when used herein have the
following meanings:

         "Adjusted LIBOR" is defined in Section 2.3(b) hereof.

         "Affiliate" means, as to any Person, any other Person which directly or
indirectly controls, or is under common control with, or is controlled by, such
Person. As used in this definition, "control" (including, with their correlative
meanings, "controlled by" and "under common control with") means possession,
directly or indirectly, of power to direct or cause the direction of management
or policies of a Person (whether through ownership of securities or partnership
or other ownership interests, by contract or otherwise), provided that, in any
event for purposes of this definition: (i) any Person which owns directly or
indirectly 5% or more of the securities having ordinary voting power for the
election of directors or other governing body of a corporation or 5% or more of
the partnership or other ownership interests of any other Person (other than as
a limited partner of such other Person) will be deemed to control such
corporation or other Person; and (ii) each director and executive officer of the
Borrower or any Subsidiary shall be deemed an Affiliate of the Borrower and each
Subsidiary.

         "Agent" is defined in the first paragraph of this Agreement and
includes any successor Agent pursuant to Section 10.7 hereof.

         "Agreement" means this 364-Day Revolving Credit Agreement, including
all Exhibits and Schedules hereto, as it may be amended, supplemented or
otherwise modified from time to time in accordance with the terms hereof.

<PAGE>   6

         "Applicable Margin" means, at any time (i) with respect to Base Rate
Loans, the Base Rate Margin and (ii) with respect to Eurocurrency Loans, the
Eurocurrency Margin.

         "Applicable Telerate Page" is defined in Section 2.3(b) hereof.

         "Authorized Representative" means those persons shown on the list of
officers provided by the Borrower pursuant to Section 6.1(e) hereof, or on any
updated such list provided by the Borrower to the Agent, or any further or
different officer of the Borrower so named by any Authorized Representative of
the Borrower in a written notice to the Agent.

         "Bank" is defined in the first paragraph of this Agreement.

         "Base Rate" is defined in Section 2.3(a) hereof.

         "Base Rate Loan" means a Loan bearing interest prior to maturity at a
rate specified in Section 2.3(a) hereof.

         "Base Rate Margin" means the percentage set forth in Schedule 1 hereto
beside the then applicable Rating.

         "Borrower" is defined in the first paragraph of this Agreement.

         "Borrowing" means the total of Loans of a single type advanced,
continued for an additional Interest Period, or converted from a different type
into such type by the Banks on a single date and for a single Interest Period.
Borrowings of Loans are made and maintained ratably from each of the Banks
according to their Percentages. A Borrowing is "advanced" on the day Banks
advance funds comprising such Borrowing to the Borrower, is "continued" on the
date a new Interest Period for the same type of Loan commences for such
Borrowing, and is "converted" when such Borrowing is changed from one type of
Loan to the other, all as requested by the Borrower pursuant to Section 2.5(a).

         "Business Day" means any day other than a Saturday or Sunday on which
Banks are not authorized or required to close in Chicago, Illinois or New York,
New York and, if the applicable Business Day relates to the borrowing or payment

              "LIBOR Index Rate" means, for any Interest Period, the rate per
         annum (rounded upwards, if necessary, to the next higher one-sixteenth
         of one percent) for deposits in U.S. Dollars for delivery on the first
         day of and for a period equal to such Interest Period in an amount
         equal or comparable to the principal amount of the Loan scheduled to be
         made by the Agent as part of such Borrowing, which appears on the
         Applicable Telerate Page, as of 11:00 a.m. (London, England time) on
         the day two (2) Business Days before the commencement of such Interest
         Period.

              "Applicable Telerate Page" means the display page designated as
         "Page 3750" on the Telerate Service (or such other page as may replace
         such pages, as appropriate, on that service or such other service as
         may be nominated by the British Bankers' Association as the information
         vendor for the purpose of displaying British Bankers' Association
         Interest Settlement Rates for deposits in U.S. Dollars).

              "Eurocurrency Reserve Percentage" means the daily average for the
         applicable Interest Period of the maximum rate, expressed as a decimal,
         at which reserves (including, without limitation, any supplemental,
         marginal and emergency reserves) are imposed during such Interest
         Period by the Board of Governors of the Federal Reserve System (or any
         successor) on "eurocurrency liabilities," as defined in such Board's
         Regulation D (or in respect of any other category of liabilities that
         includes deposits by reference to which the interest rate is determined
         or any category of extensions of credit or other assets that include
         loans by non-United States offices of any Bank to United States
         residents), subject to any amendments of such reserve requirement by
         such Board or its successor, taking into account any transitional
         adjustments thereto. For purposes of this definition, the Eurocurrency
         Loans shall be deemed to be "eurocurrency liabilities" as defined in
         Regulation D without benefit or credit for any prorations, exemptions
         or offsets under Regulation D.

              (c) Rate Determinations. The Agent shall determine each interest
         rate applicable to Obligations, and a determination thereof by the
         Agent shall be conclusive and binding except in the case of manifest
         error.

         Section 2.4 Minimum Borrowing Amounts. Each Borrowing of Base Rate
Loans and Eurocurrency Loans denominated in U.S. Dollars shall be in an amount
not less than $1,000,000 and in integral multiples of $1,000,000.

         Section 2.5 Manner of Borrowing Loans and Designating Interest Rates
Applicable to Loans.

              (a) Notice to the Agent. The Borrower shall give written notice to
         the Agent by no later than 10:00 a.m. (Chicago time) (i) at least three
         (3) Business Days before the date on which the Borrower requests the
         Banks to advance a Borrowing of Eurocurrency Loans and (ii) on the date
         the Borrower requests the Banks to advance a Borrowing of Base Rate
         Loans. The Loans included in each Borrowing shall bear interest
         initially at the type of rate specified in such notice of a new
         Borrowing. Thereafter, the Borrower may

                                       12

<PAGE>   17

         from time to time elect to change or continue the type of interest rate
         borne by each Borrowing or, subject to Section 2.4's minimum amount
         requirement for each outstanding Borrowing, a portion thereof, as
         follows: (i) if such Borrowing is of Eurocurrency Loans, on the last
         day of the Interest Period applicable thereto, the Borrower may
         continue part or all of such Borrowing as Eurocurrency Loans for an
         Interest Period or Interest Periods specified by the Borrower or
         convert part or all of such Borrowing into Base Rate Loans, (ii) if
         such Borrowing is of Base Rate Loans, on any Business Day, the Borrower
         may convert all or part of such Borrowing into Eurocurrency Loans for
         an Interest Period or Interest Periods specified by the Borrower. The
         Borrower shall give all such notices requesting the advance,
         continuation, or conversion of a Borrowing to the Agent by telephone or
         telecopy (which notice shall be irrevocable once given and, if by
         telephone, shall be promptly confirmed in writing). Notices of the
         continuation of a Borrowing of Eurocurrency Loans for an additional
         Interest Period or of the conversion of part or all of a Borrowing of
         Eurocurrency Loans into Base Rate Loans or of Base Rate Loans into
         Eurocurrency Loans must be given by no later than 10:00 a.m. (Chicago
         time) at least three (3) Business Days before the date of the requested
         continuation or conversion. All such notices concerning the advance,
         continuation, or conversion of a Borrowing shall specify the date of
         the requested advance, continuation or conversion of a Borrowing (which
         shall be a Business Day), the amount of the requested Borrowing to be
         advanced, continued, or converted, the type of Loans to comprise such
         new, continued or converted Borrowing and, if such Borrowing is to be
         comprised of Eurocurrency Loans, the Interest Period applicable
         thereto. The Borrower agrees that the Agent may rely on any such
         telephonic or telecopy notice given by any person it in good faith
         believes is an Authorized Representative without the necessity of
         independent investigation, and in the event any such notice by
         telephone conflicts with any written confirmation, such telephonic
         notice shall govern if the Agent has acted in reliance thereon. There
         may be no more than five different Interest Periods in effect at any
         one time.

              (b) Notice to the Banks. The Agent shall give prompt telephonic or
         telecopy notice to each Bank of any notice from the Borrower received
         pursuant to Section 2.5(a) above. The Agent shall give notice to the
         Borrower and each Bank by like means of the interest rate applicable to
         each Borrowing of Eurocurrency Loans and the amount thereof.

              (c) Borrower's Failure to Notify. Any outstanding Borrowing of
         Base Rate Loans shall, subject to Section 6.2 hereof, automatically be
         continued for an additional Interest Period on the last day of its then
         current Interest Period unless the Borrower has notified the Agent
         within the period required by Section 2.5(a) that it intends to convert
         such Borrowing into a Borrowing of Eurocurrency Loans or notifies the
         Agent within the period required by Section 2.8(a) that it intends to
         prepay such Borrowing. If the Borrower fails to give notice pursuant to
         Section 2.5(a) above of the continuation or conversion of any
         outstanding principal amount of a Borrowing of Eurocurrency Loans
         before the last day of its then current Interest Period within the
         period required by Section 2.5(a) and has not notified the Agent within
         the period required by Section 2.8(a) that it

                                       13

<PAGE>   18
         intends to prepay such Borrowing, such Borrowing shall automatically be
         converted into a Borrowing of Base Rate Loans, subject to Section 6.2
         hereof.

              (d) Disbursement of Loans. Not later than 11:00 a.m. (Chicago
         time) on the date of any requested advance of a new Borrowing of
         Eurocurrency Loans, and not later than 12:00 noon (Chicago time) on the
         date of any requested advance of a new Borrowing of Base Rate Loans,
         subject to Section 6 hereof, each Bank shall make available its Loan
         comprising part of such Borrowing in funds immediately available at the
         principal office of the Agent in Chicago, Illinois. The Agent shall
         make available to the Borrower Loans at the Agent's principal office in
         Chicago, Illinois or such other office as the Agent has previously
         agreed to, in writing, with the Borrower.

              (e) Agent Reliance on Bank Funding. Unless the Agent shall have
         been notified by a Bank before the date on which such Bank is scheduled
         to make payment to the Agent of the proceeds of a Loan (which notice
         shall be effective upon receipt) that such Bank does not intend to make
         such payment, the Agent may assume that such Bank has made such payment
         when due and the Agent may in reliance upon such assumption (but shall
         not be required to) make available to the Borrower the proceeds of the
         Loan to be made by such Bank and, if any Bank has not in fact made such
         payment to the Agent, such Bank shall, on demand, pay to the Agent the
         amount made available to the Borrower attributable to such Bank
         together with interest thereon in respect of each day during the period
         commencing on the date such amount was made available to the Borrower
         and ending on (but excluding) the date such Bank pays such amount to
         the Agent at a rate per annum equal to the Federal Funds Rate. If such
         amount is not received from such Bank by the Agent immediately upon
         demand, the Borrower will, on demand, repay to the Agent the proceeds
         of the Loan attributable to such Bank with interest thereon at a rate
         per annum equal to the interest rate applicable to the relevant Loan.

         Section 2.6 Interest Periods. As provided in Section 2.5(a) hereof, at
the time of each request to advance, continue, or create by conversion a
Borrowing of Eurocurrency Loans, the Borrower shall select an Interest Period
applicable to such Loans from among the available options. The term "Interest
Period" means the period commencing on the date a Borrowing of Loans is
advanced, continued, or created by conversion and ending: (a) in the case of
Base Rate Loans, on the last Business Day of the calendar quarter in which such
Borrowing is advanced, continued, or created by conversion (or on the last day
of the following calendar quarter if such Loan is advanced, continued or created
by conversion on the last Business Day of a calendar quarter), and (b) in the
case of Eurocurrency Loans, 1, 2, 3, or 6 months thereafter; provided, however,
that:


              (a) any Interest Period for a Borrowing of Base Rate Loans that
         otherwise would end after the Termination Date shall end on the
         Termination Date;

              (b) for any Borrowing of Eurocurrency Loans, the Borrower may not
         select an Interest Period that extends beyond the Termination Date;

                                       14

<PAGE>   19


              (c) whenever the last day of any Interest Period would otherwise
         be a day that is not a Business Day, the last day of such Interest
         Period shall be extended to the next succeeding Business Day, provided
         that, if such extension would cause the last day of an Interest Period
         for a Borrowing of Eurocurrency Loans to occur in the following
         calendar month, the last day of such Interest Period shall be the
         immediately preceding Business Day; and

              (d) for purposes of determining an Interest Period for a Borrowing
         of Eurocurrency Loans, a month means a period starting on one day in a
         calendar month and ending on the numerically corresponding day in the
         next calendar month; provided, however, that if there is no numerically
         corresponding day in the month in which such an Interest Period is to
         end or if such an Interest Period begins on the last Business Day of a
         calendar month, then such Interest Period shall end on the last
         Business Day of the calendar month in which such Interest Period is to
         end.

         Section 2.7 Maturity of Loans. Unless an earlier maturity is provided
for hereunder (whether by acceleration or otherwise), each Loan shall mature and
become due and payable by the Borrower on the Termination Date.

         Section 2.8 Prepayments.

              (a) The Borrower may prepay without premium or penalty and in
         whole or in part (but, if in part, then: (i) if such Borrowing is of
         Base Rate Loans, in an amount not less than $1,000,000, (ii) if such
         Borrowing is of Eurocurrency Loans in an amount not less than
         $1,000,000, and (iii) in an amount such that the minimum amount
         required for a Borrowing pursuant to Section 2.4 hereof remains
         outstanding) any Borrowing of Eurocurrency Loans upon three Business
         Days prior notice to the Agent or, in the case of a Borrowing of Base
         Rate Loans, notice delivered to the Agent no later than 10:00 a.m.
         (Chicago time) on the date of prepayment, such prepayment to be made by
         the payment of the principal amount to be prepaid and accrued interest
         thereon to the date fixed for prepayment. In the case of Eurocurrency
         Loans, such prepayment may only be made on the last day of the Interest
         Period then applicable to such Loans. The Agent will promptly advise
         each Bank of any such prepayment notice it receives from the Borrower.
         Any amount paid or prepaid before the Termination Date may, subject to
         the terms and conditions of this Agreement, be borrowed, repaid and
         borrowed again.

              (b) If the aggregate principal amount of outstanding Loans shall
         at any time for any reason exceed the Revolving Credit Commitments then
         in effect, the Borrower shall, immediately and without notice or
         demand, pay the amount of such excess to the Agent for the ratable
         benefit of the Banks as a prepayment of the Loans. Immediately upon
         determining the need to make any such prepayment the Borrower shall
         notify the Agent of such required prepayment.

              (c) Each such prepayment shall be accompanied by a payment of all
         accrued and unpaid interest on the Loans prepaid and shall be subject
         to Section 2.11.

                                       15

         Section 2.9 Default Rate. If any payment of any Obligation is not made
when due (whether by acceleration or otherwise), such Obligation shall bear
interest, computed on the basis of a year of 360 days and actual days elapsed
(except for Base Rate Loans bearing interest based on the rate described in
clause (i) of the definition of Base Rate, in which case such Loan shall bear
interest computed on the basis of a year of 365 or 366 days, as applicable, and
the actual number of days elapsed) from the date such payment was due until paid
in full, payable on demand, at a rate per annum equal to:

              (a) for any Obligation other than a Eurocurrency Loan, the sum of
         two percent (2%) plus the Base Rate Margin plus the Base Rate from time
         to time in effect; and

              (b) for any Eurocurrency Loan, the sum of two percent (2%) plus
         the rate of interest in effect thereon at the time of such default
         until the end of the Interest Period applicable thereto and,
         thereafter, at a rate per annum equal to the sum of two percent (2%)
         plus the Base Rate Margin plus the Base Rate from time to time in
         effect.

         Section 2.10 The Notes.

              (a) The Loans made to the Borrower by a Bank shall be evidenced by
         a single promissory note of the Borrower issued to such Bank in the
         form of Exhibit A hereto. Each such promissory note is hereinafter
         referred to as a "Note" and collectively such promissory notes are
         referred to as the "Notes."

              (b) Each Bank shall record on its books and records or on a
         schedule to its Note the amount of each Loan advanced, continued, or
         converted by it, all payments of principal and interest and the
         principal balance from time to time outstanding thereon, the type of
         such Loan, and, for any Eurocurrency Loan, the Interest Period and the
         interest rate applicable thereto. The record thereof, whether shown on
         such books and records of a Bank or on a schedule to any Note, shall be
         prima facie evidence as to all such matters; provided, however, that
         the failure of any Bank to record any of the foregoing or any error in
         any such record shall not limit or otherwise affect the obligation of
         the Borrower to repay all Loans made to it hereunder together with
         accrued interest thereon. At the request of any Bank and upon such Bank
         tendering to the Borrower the Note to be replaced, the Borrower shall
         furnish a new Note to such Bank to replace any outstanding Note, and at
         such time the first notation appearing on a schedule on the reverse
         side of, or attached to, such Note shall set forth the aggregate unpaid
         principal amount of all Loans, if any, then outstanding thereon.

         Section 2.11 Funding Indemnity. If any Bank shall incur any loss, cost
or expense (including, without limitation, any loss of profit, and any loss,
cost or expense incurred by reason of the liquidation or re-employment of
deposits or other funds acquired by such Bank to fund or maintain any
Eurocurrency Loan or the relending or reinvesting of such deposits or amounts
paid or prepaid to such Bank) as a result of:

                                       16


<PAGE>   21


              (a) any payment (whether by acceleration or otherwise), prepayment
         or conversion of a Eurocurrency Loan on a date other than the last day
         of its Interest Period,

              (b) any failure (because of a failure to meet the conditions of
         Section 6 or otherwise) by the Borrower to borrow or continue a
         Eurocurrency Loan, or to convert a Base Rate Loan into a Eurocurrency
         Loan, on the date specified in a notice given pursuant to Section
         2.5(a) or established pursuant to Section 2.5(c) hereof,

              (c) any failure by the Borrower to make any payment of principal
         on any Eurocurrency Loan (x) when due (whether by acceleration or
         otherwise), or (y) on the date specified in a notice of prepayment, or

              (d) any acceleration of the maturity of a Eurocurrency Loan as a
         result of the occurrence of any Event of Default hereunder,

then, upon the demand of such Bank, the Borrower shall pay to such Bank
such amount as will reimburse such Bank for such loss, cost or expense. If any
Bank makes such a claim for compensation, it shall provide to the Borrower, with
a copy to the Agent, a certificate executed by an officer of such Bank setting
forth the amount of such loss, cost or expense in reasonable detail (including
an explanation of the basis for and the computation of such loss, cost or
expense) and the amounts shown on such certificate if reasonably calculated
shall be conclusive absent manifest error.

         Section 2.12 Commitment Terminations. The Borrower shall have the right
at any time and from time to time, upon five (5) Business Days prior written
notice to the Agent, to terminate the Revolving Credit Commitments without
premium or penalty, in whole or in part, any partial termination to be (i) in an
amount not less than $5,000,000, and (ii) allocated ratably among the Banks in
proportion to their respective Percentages, provided that the Revolving Credit
Commitments may not be reduced to an amount less than the amount of all Loans
then outstanding. The Agent shall give prompt notice to each Bank of any such
termination of Commitments. Any termination of Revolving Credit Commitments
pursuant to this Section 2.12 may not be reinstated.

SECTION 3.    FEES.

         Section 3.1 Fees.

              (a) Certain Fees. The Borrower shall pay, or cause to be paid, to
         the Agent certain fees set forth in the Fee Letter at the time
         specified in the Fee Letter for payment of such amounts.

              (b) Facility Fee. For the period from the Effective Date to and
         including the Termination Date, the Borrower shall pay to the Agent for
         the ratable account of the Banks in accordance with their Percentages a
         facility fee accruing at a rate per annum equal to the Facility Fee
         Rate on the average daily amount of the Commitments (whether

                                       17


<PAGE>   22

         used or unused), or if the Commitments have expired or terminated, on
         the principal amount of Loans. Such facility fee is payable in arrears
         on the last Business Day of each calendar quarter and on the
         Termination Date, unless the Revolving Credit Commitments are
         terminated in whole on an earlier date, in which event the fee for the
         period to but not including the date of such termination shall be paid
         in whole on the date of such termination.

              (c) Closing Fees. On the Effective Date the Borrower shall pay to
         the Agent for the account of each Bank a closing fee of 0.05% on the
         amount of such Bank's Revolving Credit Commitment in effect on the
         Effective Date.

              (d) Fee Calculations. All fees payable under this Agreement shall
         be payable in U.S. Dollars and shall be computed on the basis of a year
         of 360 days, for the actual number of days elapsed. All determinations
         of the amount of fees owing hereunder (and the components thereof)
         shall be made by the Agent and shall be conclusive absent manifest
         error.

SECTION 4.    PLACE AND APPLICATION OF PAYMENTS.

         Section 4.1 Place and Application of Payments. All payments of
principal of and interest on the Loans, and of all other amounts payable by the
Borrower under this Agreement, shall be made by the Borrower to the Agent by no
later than 12:00 Noon (Chicago time) on the due date thereof at the principal
office of the Agent in Chicago, Illinois (or such other location in the United
States as the Agent may designate to the Borrower). Any payments received after
such time shall be deemed to have been received by the Agent on the next
Business Day. All such payments shall be made free and clear of, and without
deduction for, any set-off, counterclaim, levy, withholding or any other
deduction of any kind in U.S. Dollars, in immediately available funds at the
place of payment. The Agent will promptly thereafter cause to be distributed
like funds relating to the payment of principal or interest on Loans or
applicable fees ratably to the Banks and like funds relating to the payment of
any other amount payable to any Person to such Person, in each case to be
applied in accordance with the terms of this Agreement.

SECTION 5.    REPRESENTATIONS AND WARRANTIES.

         The Borrower hereby represents and warrants to each Bank as to itself
and, where the following representations and warranties apply to Subsidiaries,
as to each of its Subsidiaries, as follows:

         Section 5.1 Corporate Organization and Authority. The Borrower and each
of its Subsidiaries is duly organized, validly existing and in good standing
under the laws of its jurisdiction of organization, except where such failure to
be in good standing would not, individually or in the aggregate, have a Material
Adverse Effect. Each is duly qualified to transact business in each jurisdiction
in which such qualification is required, whether by reason of ownership or
leasing of property or the conduct of business or otherwise, except where
failure

                                       18


<PAGE>   23

to be so qualified would not, individually or in the aggregate, have a
Material Adverse Effect. Each has the power and authority required to own, lease
and operate its properties and to conduct its business as currently conducted,
except where failure to have such power and authority would not, individually or
in the aggregate, have a Material Adverse Effect.

         Section 5.2 Subsidiaries. Schedule 5.2 (as updated quarterly pursuant
to Section 7.6(b) hereof or otherwise from time to time in writing by the
Borrower) hereto identifies each Subsidiary and the jurisdiction of its
incorporation. All of the issued and outstanding shares of capital stock of each
Subsidiary are validly issued and outstanding and fully paid and nonassessable
except as set forth on Schedule 5.2 hereto. All such shares owned by the
Borrower are owned beneficially, and of record, and, except in the case of (i)
Liens granted in connection with the FinCo Revolving Loan Facility, and (ii) any
Project Finance Subsidiary, free of any Lien.

         Section 5.3 Corporate Authority and Validity of Obligations. The
Borrower has full right and authority to enter into this Agreement and the other
Credit Documents to which it is a party, to make the borrowings herein provided
for, to issue its Notes in evidence thereof, and to perform all of its
obligations under the Credit Documents to which it is a party. Each Credit
Document to which it is a party has been duly authorized, executed and delivered
by the Borrower and constitutes valid and binding obligations of the Borrower
enforceable in accordance with its terms. No Credit Document, nor the
performance or observance by the Borrower of any of the matters or things
therein provided for, contravenes any provision of law or any charter or by-law
provision of the Borrower or any material Contractual Obligation of or affecting
the Borrower or any of its Properties or results in or requires the creation or
imposition of any Lien on any of the Properties or revenues of the Borrower.

         Section 5.4 Financial Statements. All financial statements heretofore
delivered to the Banks showing historical performance of the Borrower for each
of the Borrower's fiscal years ending on or before December 31, 1999, and for
the Borrower's quarter ended September 30, 2000 have been prepared in accordance
with generally accepted accounting principles applied on a basis consistent,
except as otherwise noted therein, with that of the previous fiscal year. Each
of such financial statements fairly presents on a consolidated basis the
financial condition of the Borrower as of the dates thereof and the results of
operations for the periods covered thereby. The Borrower and its Subsidiaries
have no material contingent liabilities other than those disclosed in such
financial statements referred to in this Section 5.4 or in comments or footnotes
thereto, or in any report supplementary thereto, heretofore furnished to the
Banks. Since December 31, 1999, there has been no material adverse change in the
business, operations, Property or financial or other condition, or business
prospects, of the Borrower or any of its Subsidiaries.

         Section 5.5 No Litigation; No Labor Controversies.

              (a) Except as set forth on Schedule 5.5 (as updated quarterly
         pursuant to Section 7.6(b) hereof or otherwise from time to time in
         writing by the Borrower), there is no litigation or governmental
         proceeding pending, or to the knowledge of the Borrower,

                                       19

         threatened, against the Borrower or any Subsidiary which, if adversely
         determined, could (individually or in the aggregate) have a Material
         Adverse Effect.

              (b) Except as set forth on Schedule 5.5 (as updated quarterly
         pursuant to Section 7.6(b) hereof or otherwise from time to time in
         writing by the Borrower), there are no labor controversies pending or,
         to the best knowledge of the Borrower, threatened against the Borrower
         or any Subsidiary which could have a Material Adverse Effect.

         Section 5.6 Taxes. The Borrower and its Subsidiaries have filed all
United States federal tax returns, and all other tax returns, required to be
filed and have paid all taxes due pursuant to such returns or pursuant to any
assessment received by the Borrower or any Subsidiary, except such taxes, if
any, as are being contested in good faith and for which adequate reserves have
been provided. No notices of tax liens have been filed and no claims are being
asserted concerning any such taxes, which liens or claims are material to the
financial condition of the Borrower or any of its Subsidiaries (individually or
in the aggregate). The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries for any taxes or other governmental charges are
adequate.

         Section 5.7 Approvals. Except as contemplated by Section 7.14, no
authorization, consent, license, exemption, filing or registration with any
court or governmental department, agency or instrumentality, nor any approval or
consent of the stockholders of the Borrower or any Subsidiary or from any other
Person, is necessary to the valid execution, delivery or performance by the
Borrower or any Subsidiary of any Credit Document to which it is a party.

         Section 5.8 Validity of Notes. When executed, authenticated and
delivered pursuant to the provisions of this Agreement against payment of the
consideration therefor, the Notes will be duly issued and will constitute legal,
valid and binding obligations of the Borrower, enforceable in accordance with
their terms, except for the effect of bankruptcy, insolvency, reorganization,
moratorium and other similar laws relating to or affecting the rights of
creditors generally, and will rank pari passu with all other outstanding
unsecured indebtedness of the Borrower.

         Section 5.9 ERISA. With respect to each Plan, the Borrower and each
other member of the Controlled Group has fulfilled its obligations under the
minimum funding standards of and is in compliance in all material respects with
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and
with the Code to the extent applicable to it and has not incurred any liability
to the Pension Benefit Guaranty Corporation ("PBGC") or a Plan under Title IV of
ERISA other than a liability to the PBGC for premiums under Section 4007 of
ERISA. The Borrower does not have any contingent liabilities for any
post-retirement benefits under a Welfare Plan, other than liability for
continuation coverage described in Part 6 of Title I of ERISA.

         Section 5.10 Government Regulation. Neither the Borrower nor any
Subsidiary is an "investment company" within the meaning of the Investment
Company Act of 1940, as amended.

                                       20


<PAGE>   25


         Section 5.11 Margin Stock; Use of Proceeds. Neither the Borrower nor
any Subsidiary is engaged principally, or as one of its primary activities, in
the business of extending credit for the purpose of purchasing or carrying
margin stock ("margin stock" to have the same meaning herein as in Regulation U
of the Board of Governors of the Federal Reserve System). The proceeds of the
Loans are to be used solely for the purposes set forth in and permitted by
Section 7.10. The Borrower will not use the proceeds of any Loan in a manner
that violates any provision of Regulation U or X of the Board of Governors of
the Federal Reserve System.

         Section 5.12 Licenses and Authorizations; Compliance Laws. The Borrower
and each of its Subsidiaries has all necessary licenses, permits and
governmental authorizations to own and operate its Properties and to carry on
its business as currently conducted and contemplated. The Borrower and each of
its Subsidiaries is in compliance with all applicable laws, regulations,
ordinances and orders of any governmental or judicial authorities except for any
such law, regulation, ordinance or order which, the failure to comply therewith,
could not reasonably be expected to have a Material Adverse Effect.

         Section 5.13 Ownership of Property Liens. The Borrower and each
Subsidiary has good title to or valid leasehold interests in all its Property.
None of the Borrower's Property is subject to any Lien, except as permitted in
Section 7.9.

         Section 5.14 No Burdensome Restrictions; Compliance with Agreements.
Neither the Borrower nor any Subsidiary is (a) party or subject to any law,
regulation, rule or order, or any Contractual Obligation that (individually or
in the aggregate) could have a Material Adverse Effect or (b) in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in, nor has any event occurred (and is continuing) that
constitutes or would (whether or not with the giving of notice and/or with the
passage of time and/or the fulfillment of any other requirement) constitute, to
the knowledge of the Borrower, a default or any breach or failure to perform by
the Borrower under any indenture, mortgage, loan agreement, lease or other
agreement or instrument to which it is a party, which default could have a
Material Adverse Effect.

         Section 5.15 Full Disclosure. All information heretofore furnished by
the Borrower to the Agent or any Bank for purposes of or in connection with the
Credit Documents or any transaction contemplated thereby is, and all such
information hereafter furnished by the Borrower to the Agent or any Bank will
be, true and accurate in all material respects and not misleading on the date as
of which such information is stated or certified.

         Section 5.16 Year 2000 Problem. On the basis of a comprehensive review
and assessment of the Borrower's and its Subsidiaries' systems and equipment and
inquiry made of the Borrower's and its Subsidiaries' material suppliers, vendors
and customers, and based on its operations since January 1, 2000, the Borrower
has no reason to believe that the Year 2000 Problem, including costs of
remediation, has resulted or will result in a Material Adverse Effect. As used
herein, "Year 2000 Problem" means any significant risk that computer hardware,
software or equipment containing embedded microchips essential to the businesses
or operations of the Borrower and its Subsidiaries will not, in the case of
dates or time periods occurring after

                                       21


<PAGE>   26

         December 31, 1999, function at least as effectively as in the case of
         dates or time periods occurring prior to January 1, 2000.

         with its provisions, except that if any such representation or warranty
         relates solely to an earlier date it need only remain true as of such
         date, provided that solely for purposes of this Section 6.2(b) the
         representations relating to the Borrower's Subsidiaries set forth in

business of its Subsidiary.

         Section 7.3 Taxes. The Borrower will duly pay and discharge, and will
cause each of its Subsidiaries duly to pay and discharge, all taxes, rates,

been provided therefor on the books of the Borrower.

any reportable event (as defined in ERISA) affecting a Plan, other than any such
event of which the PBGC has waived notice by regulation, (ii) receipt of any
notice from PBGC of its intention to seek termination of any Plan or appointment
of a trustee therefor, (iii) its intention to terminate or withdraw from any
Plan, and (iv) the occurrence of any event affecting any Plan which could result

Bank any notice it receives from the Borrower pursuant to this Section 7.4.

companies similarly situated and conducting similar businesses, the Borrower
will also insure, and cause each of its Subsidiaries to insure, employers' and
public and product liability risks with good and responsible insurance
companies. The Borrower will upon request of the Agent furnish to the Agent a
summary setting forth the nature and extent of the insurance maintained pursuant
to this Section 7.5.

              (a) The Borrower will maintain a system of accounting in
         accordance with GAAP and will furnish to the Banks and their respective

         need only remain true as of such date), taking into account any
         amendments to such Section (including, without limitation, any
         amendments to the Schedules referenced therein) made after the date of
         this Agreement in accordance with its provisions and except as

Subsidiaries, to examine all of their books of account, records, reports and
other papers, to make copies and extracts therefrom, and to discuss their
respective affairs, finances and accounts with their respective officers,

the Borrower authorizes such accountants to discuss with the Banks (and such
Persons as any Bank may designate subject to confidentiality agreements
reasonably acceptable to the Borrower) the finances and affairs of the Borrower
and its Subsidiaries) all at such reasonable times and as often as may be
reasonably requested; provided, however, that except upon the occurrence and
during the continuation of any Default or Event of Default, not more than one
such set of visits and inspections may be conducted each calendar quarter.

times rank at least pari passu with all other senior unsecured obligations of
the Borrower. The Borrower will not create, incur, permit to exist or to be
incurred any Lien of any kind on any Property owned by the Borrower; provided,
however, that this Section 7.9 shall not apply to nor operate to prevent:

              (a) Liens upon any Property acquired by the Borrower to secure any
         Indebtedness (which for purposes of this Section 7.9(a) shall include
         non-recourse obligations) of the Borrower incurred to finance or
         refinance the purchase price of such Property (including Property which
         was initially purchased with equity), provided that any such Lien shall
         apply only to the Property that was so acquired and the aggregate
         principal amount of Indebtedness secured by such Liens shall not exceed
         the cost or value of the acquired Property;

              (b) Other Liens not to exceed 10% of Consolidated Net Tangible
         Assets;

              (c) Liens on the stock or other equity interests (i) granted in
         connection with the FinCo Revolving Loan Facility and (ii) of Project
         Finance Subsidiaries; and

              (d) Any extension, renewal or replacement (or successive
         extensions, renewals or replacements) in whole or in part of any Lien
         referred to in the foregoing paragraphs (a) through (c), inclusive.

         Section 7.10 Use of Proceeds; Regulation U. The proceeds of each
Borrowing will be used by the Borrower to repay indebtedness outstanding under
the Existing Credit Agreement, and for working capital and general corporate
purposes. The Borrower will not use any part of the proceeds of any of the
Borrowings directly or indirectly to purchase or carry any margin stock (as
defined in Section 5.11 hereof) or to extend credit to others for the purpose of
purchasing or carrying any such margin stock.

         Section 7.11 Mergers, Consolidations and Sales of Assets.

              (a) The Borrower will not consolidate with or merge into any other
         Person or sell, convey, transfer or lease its properties and assets
         substantially as an entirety to any Person, and the Borrower shall not
         permit any Person to consolidate with or merge into the Borrower,
         unless: (i) immediately prior to and immediately following such
         consolidation, merger, sale or lease, and after giving effect thereto,
         no Default or Event of Default shall have occurred and be continuing;
         and (ii) the Borrower is the surviving or continuing corporation, or
         the surviving or continuing corporation that acquires by sale,
         conveyance, transfer or lease (a) has a Rating equal to or better than
         the Rating of the Borrower in effect prior to such consolidation or
         merger and (y) is incorporated in the


                                       27

         United States and expressly assumes the payment and performance of all
         Obligations of the Borrower under the Credit Documents pursuant to
         documentation in form and substance satisfactory to the Required Banks.

              (b) Except for the sale of the properties and assets of the
         Borrower substantially as an entirety pursuant to subsection (a) above,
         and other than assets required to be sold to conform with governmental
         regulations, the Borrower shall not sell or otherwise dispose of any
         assets (other than short-term, readily marketable investments purchased
         for cash management purposes with funds not representing the proceeds
         of other asset sales) if on a pro forma basis, the aggregate net book
         value of all such sales during the most recent 12-month period would
         exceed ten percent (10%) of Consolidated Net Tangible Assets computed
         as of the end of the most recent fiscal quarter preceding such sale;
         provided, however, that any such sales -------- ------- shall be
         disregarded for purposes of this ten percent (10%) limitation if the
         proceeds are invested in assets in similar or related lines of business
         of the Borrower and, provided further, that the Borrower may sell or
         otherwise dispose of assets in excess of such ten percent (10%) if the
         proceeds from such sales or dispositions, which are not reinvested as
         provided above, are retained by the Borrower as cash or cash
         equivalents at all times until invested in assets in similar or related
         lines of business of the Borrower.

         Section 7.12 Consolidated Net Worth. The Borrower will at all times
cause its Consolidated Net Worth to be equal to or greater than the Minimum
Consolidated Net Worth.

         Section 7.13 Indebtedness to Consolidated Capitalization. The Borrower
will at the end of each of its fiscal quarters maintain a ratio of its
Indebtedness to Consolidated Capitalization of not more than 0.68 to 1.00,
provided that for not more than two consecutive months in any six month period
(any such two month period being referred to herein as a "Non-Conforming
Period"), the ratio of the Borrower's Indebtedness to Consolidated
Capitalization may increase to not more than 0.72 to 1.00 so long as the
Borrower delivers to the Agent within 30 days after the end of any such
Non-Conforming Period written affirmation from Moody's Investors Service, Inc.
and Standard and Poor's Ratings Service, Inc. that the respective Ratings which
were in effect prior to such Non-Conforming Period remains in effect and that
the Borrower has not been placed in any "credit-watch with negative
implications" or similar type of category. For purposes of this covenant, only
fifty percent (50%) of any Indebtedness of the Borrower constituting Performance
Guarantees of obligations of the Borrower's Affiliates shall be deemed
Indebtedness, provided that if any demand has been made on such guarantee, the
full amount of such guarantee shall be included in calculating Indebtedness.

         Section 7.14 Compliance with Laws. Without limiting any of the other
covenants of the Borrower in this Section 7, the Borrower will conduct its
business, and otherwise be, in compliance with all applicable laws, regulations,
ordinances, writs, judgments, injunctions, decrees, awards and orders of any
governmental or judicial authorities; provided, however, that the Borrower shall
not be required to comply with any such law, rule, regulation, ordinance, writ,
judgments, injunction, decree, award or order if the failure to comply therewith
could not reasonably be expected to have a Material Adverse Effect.

                                       28

         Section 7.15 PUHCA. The Borrower has obtained, and will maintain in
full force and effect, all necessary approvals, if any, under the Public Utility
Holding Company Act of 1935, as amended, in connection with the Borrower's
performance under the Credit Documents.

SECTION 8.    EVENTS OF DEFAULT AND REMEDIES.

         Section 8.1 Events of Default. Any one or more of the following shall
constitute an Event of Default:

              (a) The Borrower shall (i) fail to make when due any payment of

         to the Credit Documents or any other instrument, document or agreement

         the date as of which the facts set forth are stated or certified or
         deemed to have been stated or certified;

              (c) The Borrower shall fail to comply with Section 7 hereof and
         such failure to comply shall continue for 30 calendar days after the

         (ii) first actual knowledge thereof by an officer of the Borrower;

              (d) The Borrower shall fail to comply with any agreement,
         covenant, condition, provision or term contained in the Credit
         Documents (and such failure shall not constitute an Event of Default

         to comply shall continue for 30 calendar days after the earlier to
         occur of (i) notice thereof to the Borrower by the Agent and (ii) first
         actual knowledge thereof by an officer of the Borrower;

         substantial part of the property thereof and shall not be discharged
         within 90 days;

              (f) Any bankruptcy, reorganization, debt arrangement or other

                                       29
<PAGE>   34

         been consented to or acquiesced in by the Borrower, or shall remain
         undismissed for 90 days, or an order for relief shall have been entered

         to approve institution of, or acquiescence in, such a proceeding;

              (g) Any dissolution or liquidation proceeding shall be instituted
         by or against the Borrower and, if instituted against the Borrower,
         shall be consented to or acquiesced in by the Borrower or shall remain
         for 90 days undismissed, or the Borrower shall take any corporate

         proceeding;

              (h) A judgment or judgments, decrees or orders of any court,

              (i) The institution by the Borrower of steps to terminate any Plan
         if in order to effectuate such termination, the Borrower would be
         required to make a contribution to such Plan, or would incur a
         liability or obligation to such Plan, in excess of $50,000,000, or the
         institution by the PBGC of steps to terminate any Plan;

              (j) Either (A) a default shall occur under that certain Credit

         banks party thereto and Australia and New Zealand Banking Group
         Limited, as Administrative Agent, as such agreement may from time to

         beneficiary of such indebtedness or a trustee therefor to cause the
         acceleration of the maturity of any such indebtedness of principal of
         or any interest aggregating $50,000,000 or more or any mandatory

         Section 8.2 Non-Bankruptcy Defaults. When any Event of Default other
than those described in subsections (e), (f) or (g) of Section 8.1 hereof has
occurred and is continuing, the Agent shall, by written notice to the Borrower:
(a) if so directed by the Required Banks, terminate the remaining Commitments
and all other obligations of the Banks hereunder on the date stated in such
notice (which may be the date thereof); and (b) if so directed by the Required
Banks, declare the principal of and the accrued interest on all outstanding
Notes to be forthwith due and payable and thereupon all outstanding Notes,
including both principal and interest thereon, shall be and become immediately
due and payable together with all other amounts payable under the Credit
Documents without further demand, presentment, protest or notice of any kind.
The Agent, after giving notice to the Borrower pursuant to Section 8.1(c),
8.1(d) or this Section 8.2, shall also promptly send a copy of such notice to
the other Banks, but the failure to do so shall not impair or annul the effect
of such notice.

         Section 8.3 Bankruptcy Defaults. When any Event of Default described in
subsections (e), (f) or (g) of Section 8.1 hereof has occurred and is
continuing, then all outstanding Notes shall immediately and automatically
become due and payable together with all other amounts payable under the Credit
Documents without presentment, demand, protest or notice of any kind and the
obligation of the Banks to extend further credit pursuant to any of the terms
hereof shall immediately and automatically terminate.

         Section 8.4 [Intentionally Omitted]

         Section 8.5 Notice of Default. The Agent shall give notice to the
Borrower under Section 8.1(c) or 8.1(d) hereof promptly upon being requested to

         Section 8.6 Expenses. The Borrower agrees to pay to the Agent and each
Bank, and any other holder of any Note outstanding hereunder, all reasonable
costs and expenses incurred or paid by the Agent or such Bank or any such
holder, including attorneys' fees and court costs, in connection with any
Default or Event of Default by the Borrower hereunder or in connection with the
enforcement of any of the Credit Documents.

SECTION 9.    CHANGE IN CIRCUMSTANCES.

         Section 9.1 Change of Law. Notwithstanding any other provisions of this
Agreement or any Note if at any time after the date hereof any change in
applicable law or regulation or in the interpretation thereof makes it unlawful
for any Bank to make or continue to maintain Eurocurrency Loans or to perform
its obligations as contemplated hereby, such Bank shall promptly give notice
thereof to the Borrower and such Bank's obligations to make or maintain
Eurocurrency Loans under this Agreement shall terminate until it is no longer
unlawful for such Bank to make or maintain Eurocurrency Loans. The Borrower
shall prepay on demand the outstanding principal amount of any such affected
Eurocurrency Loans, together with all interest accrued thereon at a rate per
annum equal to the interest rate applicable to such Loan; provided, however,
subject to all of the terms and conditions of this Agreement, the Borrower may
then elect to borrow the principal amount of the affected Eurocurrency Loans
from such Bank by

                                       31
<PAGE>   36

         means of Base Rate Loans from such Bank, which Base Rate Loans shall
         not be made ratably by the Banks but only from such affected Bank.

         Section 9.2 Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any Borrowing of Loans:

              (a) the Agent determines that deposits in U.S. Dollars (in the
         applicable amounts) are not being offered to it in the federal funds or
         eurocurrency interbank market, as applicable, for such Interest Period,
         or that by reason of circumstances affecting the federal funds or
         interbank eurocurrency market, as applicable, adequate and reasonable
         means do not exist for ascertaining the applicable Federal Funds Rate
         or LIBOR; or

              (b) Banks having 25% or more of the aggregate amount of the
         Revolving Credit Commitments reasonably determine and so advise the
         Agent that the Federal Funds Rate or LIBOR, as applicable, as
         reasonably determined by the Agent will not adequately and fairly
         reflect the cost to such Banks or Bank of funding their or its Loans or
         Loan for such Interest Period;

then the Agent shall forthwith give notice thereof to the Borrower and the
Banks, whereupon until the Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks or
of the relevant Bank to make Base Rate Loans bearing interest at the Federal
Funds Rate or Eurocurrency Loans in the currency so affected, as applicable,
shall be suspended.

         Section 9.3 Increased Cost and Reduced Return.

              (a) If, on or after the date hereof, the adoption of any
         applicable law, rule or regulation, or any change therein, or any
         change in the interpretation or administration thereof by any
         governmental authority, central bank or comparable agency charged with
         the interpretation or administration thereof, or compliance by any Bank
         (or its Lending Office) with any request or directive (whether or not
         having the force of law but, if not having the force of law, compliance
         with which is customary in the relevant jurisdiction) of any such
         authority, central bank or comparable agency:

                   (i) shall subject any Bank (or its Lending Office) to any
              tax, duty or other charge with respect to its Eurocurrency Loans,
              its Notes, or its obligation to make Eurocurrency Loans, or shall
              change the basis of taxation of payments to any Bank (or its
              Lending Office) of the principal of or interest on its
              Eurocurrency Loans, or any other amounts due under this Agreement
              in respect of its Eurocurrency Loans or its obligation to make
              Eurocurrency Loans (except for changes in the rate of tax on the
              overall net income or profits of such Bank or its Lending Office
              imposed by the jurisdiction in which such Bank or its lending
              office is incorporated in which such Bank's principal executive
              office or Lending Office is located); or

                                       32
<PAGE>   37


                   (ii) shall impose, modify or deem applicable any reserve,
              special deposit or similar requirement (including, without
              limitation, any such requirement imposed by the Board of Governors
              of the Federal Reserve System, but excluding with respect to any
              Eurocurrency Loans any such requirement included in an applicable
              Eurocurrency Reserve Percentage) against assets of, deposits with
              or for the account of, or credit extended by, any Bank (or its
              Lending Office) or shall impose on any Bank (or its Lending
              Office) or on the interbank market any other condition affecting
              its Eurocurrency Loans, its Notes, or its obligation to make
              Eurocurrency Loans;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Lending Office) of making or maintaining any Eurocurrency Loan, or to reduce
the amount of any sum received or receivable by such Bank (or its Lending
Office) under this Agreement or under its Notes with respect thereto, by an
amount deemed by such Bank to be material, then, within fifteen (15) days after
demand by such Bank (with a copy to the Agent), the Borrower shall be obligated
to pay to such Bank such additional amount or amounts as will compensate such
Bank for such increased cost or reduction. In the event any law, rule,
regulation or interpretation described above is revoked, declared invalid or
inapplicable or is otherwise rescinded, and as a result thereof a Bank is
determined to be entitled to a refund from the applicable authority for any
amount or amounts which were paid or reimbursed by Borrower to such Bank
hereunder, such Bank shall, so long as no Event of Default has occurred and is
then continuing, refund such amount or amounts to Borrower without interest.

              (b) If, after the date hereof, any Bank or the Agent shall have
         determined that the adoption of any applicable law, rule or regulation
         regarding capital adequacy, or any change therein (including, without
         limitation, any revision in the Final Risk-Based Capital Guidelines of
         the Board of Governors of the Federal Reserve System (12 CFR Part 208,
         Appendix A; 12 CFR Part 225, Appendix A) or of the Office of the
         Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any
         other applicable capital rules heretofore adopted and issued by any
         governmental authority), or any change in the interpretation or
         administration thereof by any governmental authority, central bank or
         comparable agency charged with the interpretation or administration
         thereof, or compliance by any Bank (or its Lending Office) with any
         request or directive regarding capital adequacy (whether or not having
         the force of law but, if not having the force of law, compliance with
         which is customary in the applicable jurisdiction) of any such
         authority, central bank or comparable agency, has or would have the
         effect of reducing the rate of return on such Bank's capital, or on the
         capital of any corporation controlling such Bank, as a consequence of
         its obligations hereunder to a level below that which such Bank could
         have achieved but for such adoption, change or compliance (taking into
         consideration such Bank's policies with respect to capital adequacy) by
         an amount deemed by such Bank to be material, then from time to time,
         within fifteen (15) days after demand by such Bank (with a copy to the
         Agent), the Borrower shall pay to such Bank such additional amount or
         amounts as will compensate such Bank for such reduction.

                                       33
<PAGE>   38


              (c) Each Bank that determines to seek compensation under this
         Section 9.3 shall notify the Borrower and the Agent of the
         circumstances that entitle the Bank to such compensation pursuant to
         this Section 9.3 and will designate a different Lending Office if such
         designation will avoid the need for, or reduce the amount of, such
         compensation and will not, in the sole judgment of such Bank, be
         otherwise disadvantageous to such Bank. A certificate of any Bank
         claiming compensation under this Section 9.3 and setting forth the
         additional amount or amounts to be paid to it hereunder shall be
         conclusive in the absence of manifest error. In determining such
         amount, such Bank may use any reasonable averaging and attribution
         methods.

              (d) If any Bank (other than ABN AMRO Bank N.V.) has demanded
         compensation or given notice of its intention to demand compensation
         under this Section 9.3 or the Borrower is required to pay any
         additional amount to any Bank under Section 9.3, the Borrower shall
         have the right, with the assistance of the Agent, to seek a substitute
         Bank or Banks reasonably satisfactory to the Agent (which may be one or
         more of the Banks) to replace such Bank under this Agreement and on the
         date of replacement, the Borrower shall pay all accrued interest and
         fees to the Bank being replaced. The Bank to be so replaced shall
         cooperate with the Borrower and substitute Bank to accomplish such
         substitution, provided that all of such Bank's Loan Commitment is
         replaced.

         Section 9.4 Lending Offices. Each Bank may, at its option, elect to
make its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof or in the assignment agreement which any
assignee bank executes pursuant to Section 11.12 hereof (each a "Lending
Office") for each type of Loan available hereunder or at such other of its
branches, offices or affiliates as it may from time to time elect and designate
in a written notice to the Borrower and the Agent.

         Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding
any other provision of this Agreement, each Bank shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if each Bank had actually funded and
maintained each Eurocurrency Loan through the purchase of deposits of U.S.
Dollars in the eurocurrency interbank market having a maturity corresponding to
such Loan's Interest Period and bearing an interest rate equal to LIBOR for such
Interest Period.

SECTION 10.   THE AGENT.

         Section 10.1 Appointment and Authorization of Agent. Each Bank hereby
appoints ABN AMRO Bank N.V. as the Agent under the Credit Documents and hereby
authorizes the agent to take such action as Agent on its behalf and to exercise
such powers under the Credit Documents as are delegated to the Agent by the
terms thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no duties or responsibilities except those expressly set
forth in this


                                       34
<PAGE>   39
Agreement and the Credit Documents. The duties of the Agent shall be mechanical
and administrative in nature; the Agent shall not have by reason of this
Agreement or any other Credit Document a fiduciary relationship in respect of
any Bank, the holder of any Note or any other Person; and nothing in this
Agreement or any other Credit Document, expressed or implied, is intended to or
shall be so construed as to impose upon the Agent any obligations in respect of
this Agreement or any other Credit Document except as expressly set forth herein
or therein.

         Section 10.2 Agent and its Affiliates. The Agent shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Bank and may exercise or refrain from exercising the same as though it
were not the Agent, and the Agent and its affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with the Borrower or
any Affiliate of the Borrower as if it were not the Agent under the Credit
Documents. The term "Bank" as used herein and in all other Credit Documents,
unless the context otherwise clearly requires, includes the Agent in its
individual capacity as a Bank. References in Section 2 hereof to the Agent's
Loans, or to the amount owing to the Agent for which an interest rate is being
determined, refer to the Agent in its individual capacity as a Bank.

         Section 10.3 Action by Agent. If the Agent receives from the Borrower a
written notice of an Event of Default pursuant to Section 7.6(c)(i) hereof, the
Agent shall promptly give each of the Banks written notice thereof. The
obligations of the Agent under the Credit Documents are only those expressly set
forth therein. Without limiting the generality of the foregoing, the Agent shall
not be required to take any action hereunder with respect to any Default or
Event of Default, except as expressly provided in Sections 8.2 and 8.5. In no
event, however, shall the Agent be required to take any action in violation of
applicable law or of any provision of any Credit Document, and the Agent shall
in all cases be fully justified in failing or refusing to act hereunder or under
any other Credit Document unless it shall be first indemnified to its reasonable
satisfaction by the Banks against any and all costs, expense, and liability
which may be incurred by it by reason of taking or continuing to take any such
action. The Agent shall be entitled to assume that no Default or Event of
Default exists unless notified to the contrary by a Bank or the Borrower. In all
cases in which this Agreement and the other Credit Documents do not require the
Agent to take certain actions, the Agent shall be fully justified in using its
discretion in failing to take or in taking any action hereunder and thereunder.

         Section 10.4 Consultation with Experts. The Agent may consult with
legal counsel, independent public accountants and other experts selected by it
and shall not be liable for any action taken or omitted to be taken by it in
good faith in accordance with the advice of such counsel, accountants or
experts.

         Section 10.5 Liability of Agent; Credit Decision. Neither the Agent nor
any of its directors, officers, agents, or employees shall be liable for any
action taken or not taken by it in connection with the Credit Documents (i) with
the consent or at the request of the Required Banks or (ii) in the absence of
its own gross negligence or willful misconduct. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into or verify: (i) any statement, warranty or
representation made in connection with this Agreement, any other Credit Document
or any Credit Event; (ii) the performance or observance of any of the covenants
or agreements of the Borrower or any other party contained


                                       35
<PAGE>   40
herein or in any other Credit Document; (iii) the satisfaction of any condition
specified in Section 6 hereof, except receipt of items required to be delivered
to the Agent; or (iv) the validity, effectiveness, genuineness, enforceability,
perfection, value, worth or collectability hereof or of any other Credit
Document or of any other documents or writing furnished in connection with any
Credit Document; and the Agent makes no representation of any kind or character
with respect to any such matter mentioned in this sentence. The Agent may
execute any of its duties under any of the Credit Documents by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Banks, the Borrower, or any other Person for the default or misconduct of any
such agents or attorneys-in-fact selected with reasonable care. The Agent shall
not incur any liability by acting in reliance upon any notice, consent,
certificate, other document or statement (whether written or oral) believed by
it to be genuine or to be sent by the proper party or parties. In particular and
without limiting any of the foregoing, the Agent shall have no responsibility
for confirming the accuracy of any Compliance Certificate or other document or
instrument received by it under the Credit Documents. The Agent may treat the
payee of any Note as the holder thereof until written notice of transfer shall
have been filed with the Agent signed by such payee in form satisfactory to the
Agent. Each Bank acknowledges that it has independently and without reliance on
the Agent or any other Bank, and based upon such information, investigations and
inquiries as it deems appropriate, made its own credit analysis and decision to
extend credit to the Borrower in the manner set forth in the Credit Documents.
It shall be the responsibility of each Bank to keep itself informed as to the
creditworthiness of the Borrower and any other relevant Person, and the Agent
shall have no liability to any Bank with respect thereto.

         Section 10.6 Indemnity. The Banks shall ratably, in accordance with
their respective Percentages, indemnify and hold the Agent, and its directors,
officers, employees, agents and representatives harmless from and against any
liabilities, losses, costs or expenses suffered or incurred by it under any
Credit Document or in connection with the transactions contemplated thereby,
regardless of when asserted or arising, except to the extent they are promptly
reimbursed for the same by the Borrower and except to the extent that any event
giving rise to a claim was caused by the gross negligence or willful misconduct
of the party seeking to be indemnified. The obligations of the Banks under this
Section 10.6 shall survive termination of this Agreement.

         Section 10.7 Resignation of Agent and Successor Agent. The Agent may
resign at any time by giving written notice thereof to the Banks and the
Borrower. Upon any such resignation of the Agent, the Required Banks shall have
the right to appoint a successor Agent with the consent of the Borrower,
provided, that at any time an Event of Default has occurred and is continuing,
no such consent shall be required. If no successor Agent shall have been so
appointed by the Required Banks, and shall have accepted such appointment,
within thirty (30) days after the retiring Agent's giving of notice of
resignation, then the retiring Agent may, on behalf of the Banks, with the
consent of the Borrower, appoint a successor Agent, which shall be any Bank
hereunder or any commercial bank organized under the laws of the United States
of America or of any State thereof and having a combined capital and surplus of
at least $200,000,000. Upon the acceptance of its appointment as the Agent
hereunder, such successor Agent shall thereupon succeed to and become vested
with all the rights and duties of the retiring or removed Agent under the Credit
Documents, and the retiring Agent shall be discharged from


                                       36
<PAGE>   41

its duties and obligations thereunder. After any retiring Agent's resignation
hereunder as Agent, the provisions of this Section 10 and all protective
provisions of the other Credit Documents shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent.

SECTION 11.   MISCELLANEOUS.

         Section 11.1 Withholding Taxes.

              (a) Payments Free of Withholding. Subject to Section 11.1(b)
         hereof, each payment by the Borrower under this Agreement or the other
         Credit Documents shall be made without withholding for or on account of
         any present or future taxes (other than overall net income taxes on the
         recipient). If any such withholding is so required, the Borrower shall
         make the withholding, pay the amount withheld to the appropriate
         governmental authority before penalties attach thereto or interest
         accrues thereon and forthwith pay such additional amount as may be
         necessary to ensure that the net amount actually received by each Bank
         and the Agent free and clear of such taxes (including such taxes on
         such additional amount) is equal to the amount which that Bank or the
         Agent (as the case may be) would have received had such withholding not
         been made. If the Agent or any Bank pays any amount in respect of any
         such taxes, penalties or interest the Borrower shall reimburse the
         Agent or that Bank for that payment on demand in the currency in which
         such payment was made. If the Borrower pays any such taxes, penalties
         or interest, it shall deliver official tax receipts evidencing that
         payment or certified copies thereof to the Bank or Agent on whose
         account such withholding was made (with a copy to the Agent if not the
         recipient of the original) on or before the thirtieth day after
         payment. If any Bank or the Agent determines it has received or been
         granted a credit against or relief or remission for, or repayment of,
         any taxes paid or payable by it because of any taxes, penalties or
         interest paid by the Borrower and evidenced by such a tax receipt, such
         Bank or Agent shall, to the extent it can do so without prejudice to
         the retention of the amount of such credit, relief, remission or
         repayment, pay to the Borrower such amount as such Bank or Agent
         determines is attributable to such deduction or withholding and which
         will leave such Bank or Agent (after such payment) in no better or
         worse position than it would have been in if the Borrower had not been
         required to make such deduction or withholding. Nothing in this
         Agreement shall interfere with the right of each Bank and the Agent to
         arrange its tax affairs in whatever manner it thinks fit nor oblige any
         Bank or the Agent to disclose any information relating to its tax
         affairs or any computations in connection with such taxes.

              (b) U.S. Withholding Tax Exemptions. Each Bank that is not a
         United States person (as such term is defined in Section 7701(a)(30) of
         the Code) shall submit to the Borrower and the Agent on or before the
         earlier of the date the initial Borrowing is made hereunder and thirty
         (30) days after the date hereof, two duly completed and signed copies
         of either Form W8BEN (relating to such Bank and entitling it to a
         complete exemption from withholding under the Code on all amounts to be
         received by such Bank, including fees, pursuant to the


                                       37
<PAGE>   42

         Credit Documents and the Loans) or Form W8ECI (relating to all amounts
         to be received by such Bank, including fees, pursuant to the Credit
         Documents and the Loans) of the United States Internal Revenue Service.
         Thereafter and from time to time, each Bank shall submit to the
         Borrower and the Agent such additional duly completed and signed copies
         of one or the other of such Forms (or such successor forms as shall be
         adopted from time to time by the relevant United States taxing
         authorities) as may be (i) requested by the Borrower in a written
         notice, directly or through the Agent, to such Bank and (ii) required
         under then-current United States law or regulations to avoid or reduce
         United States withholding taxes on payments in respect of all amounts
         to be received by such Bank, including fees, pursuant to the Credit
         Documents or the Loans.

              (c) Inability of Bank to Submit Forms. If any Bank determines, as
         a result of any change in applicable law, regulation or treaty, or in
         any official application or interpretation thereof, that it is unable
         to submit to the Borrower or Agent any form or certificate that such
         Bank is obligated to submit pursuant to subsection (b) of this Section
         11.1 or that such Bank is required to withdraw or cancel any such form
         or certificate previously submitted or any such form or certificate
         otherwise becomes ineffective or inaccurate, such Bank shall promptly
         notify the Borrower and Agent of such fact and the Bank shall to that
         extent not be obligated to provide any such form or certificate and
         will be entitled to withdraw or cancel any affected form or
         certificate, as applicable.

         Section 11.2 No Waiver of Rights. No delay or failure on the part of
the Agent or any Bank or on the part of the holder or holders of any Note in the
exercise of any power or right under any Credit Document shall operate as a
waiver thereof, nor as an acquiescence in any default, nor shall any single or
partial exercise thereof preclude any other or further exercise of any other
power or right, and the rights and remedies hereunder of the Agent, the Banks
and the holder or holders of any Notes are cumulative to, and not exclusive of,
any rights or remedies which any of them would otherwise have.

         Section 11.3 Non-Business Day. If any payment of principal or interest
on any Loan or of any other Obligation shall fall due on a day which is not a
Business Day, interest or fees (as applicable) at the rate, if any, such Loan or
other Obligation bears for the period prior to maturity shall continue to accrue
on such Obligation from the stated due date thereof to and including the next
succeeding Business Day, on which the same shall be payable.

         Section 11.4 Documentary Taxes. The Borrower agrees that it will pay
any documentary, stamp or similar taxes payable in respect to any Credit
Document, including interest and penalties, in the event any such taxes are
assessed, irrespective of when such assessment is made and whether or not any
credit is then in use or available hereunder.

         Section 11.5 Survival of Representations. All representations and
warranties made herein or in certificates given pursuant hereto shall survive
the execution and delivery of this Agreement and the other Credit Documents, and
shall continue in full force and effect with respect to the date as of which
they were made as long as any credit is in use or available hereunder.

                                       38
<PAGE>   43


         Section 11.6 Survival of Indemnities. All indemnities and all other
provisions relative to reimbursement to the Banks of amounts sufficient to
protect the yield of the Banks with respect to the Loans, including, but not
limited to, Section 2.11, Section 9.3 and Section 11.15 hereof, shall survive
the termination of this Agreement and the other Credit Documents and the payment
of the Loans and all other Obligations.

         Section 11.7 Set-Off.

              (a) In addition to any rights now or hereafter granted under
         applicable law and not by way of limitation of any such rights, upon
         the occurrence of any Event of Default, each Bank, each Affiliate of a
         Bank, and each subsequent holder of any Note is hereby authorized by
         the Borrower at any time or from time to time, without notice to the
         Borrower or to any other Person, any such notice being hereby expressly
         waived, to set off and to appropriate and to apply any and all deposits
         (general or special, including, but not limited to, Indebtedness
         evidenced by certificates of deposit, whether matured or unmatured, and
         in whatever currency denominated) and any other Indebtedness at any
         time held or owing by that Bank, its Affiliate or that subsequent
         holder to or for the credit or the account of the Borrower, whether or
         not matured, against and on account of the obligations and liabilities
         of the Borrower to that Bank, its Affiliate or that subsequent holder
         under the Credit Documents, including, but not limited to, all claims
         of any nature or description arising out of or connected with the
         Credit Documents, irrespective of whether or not (a) that Bank, its
         Affiliate or that subsequent holder shall have made any demand
         hereunder or (b) the principal of or the interest on the Loans or Notes
         and other amounts due hereunder shall have become due and payable
         pursuant to Section 8 and although said obligations and liabilities, or
         any of them, may be contingent or unmatured.

              (b) Each Bank agrees with each other Bank a party hereto that if
         such Bank shall receive and retain any payment, whether by set-off or
         application of deposit balances or otherwise, on any of the Loans in
         excess of its ratable share of payments on all such obligations then
         outstanding to the Banks, then such Bank shall purchase for cash at
         face value, but without recourse, ratably from each of the other Banks
         such amount of the Loans, or participations therein, held by each such
         other Bank (or interest therein) as shall be necessary to cause such
         Bank to share such excess payment ratably with all the other Banks;
         provided, however, that if any such purchase is made by any Bank, and
         if such excess payment or part thereof is thereafter recovered from
         such purchasing Bank, the related purchases from the other Banks shall
         be rescinded ratably and the purchase price restored as to the portion
         of such excess payment so recovered, but without interest unless the
         purchasing Bank is required to pay interest thereon, in which case each
         Bank returning funds to such purchasing Bank shall pay its pro rata
         share of such interest.

         Section 11.8 Notices. Except as otherwise specified herein, all notices
under the Credit Documents shall be in writing (including telecopy or other
electronic communication) and shall be given to a party hereunder at its address
or telecopier number set forth below or such other address or telecopier number
as such party may hereafter specify by notice to the Agent and the Borrower,
given by courier, by United States certified or registered mail, or by other

Each such notice, request or other communication shall be effective (i) if given
by telecopier, when such telecopy is transmitted to the telecopier number
specified in this Section 11.8 or on the signature pages hereof and a
confirmation of receipt of such telecopy has been received by the sender, (ii)
if given by courier, when delivered, (iii) if given by mail, three business days
after such communication is deposited in the mail, registered with return
receipt requested, addressed as aforesaid or (iv) if given by any other means,
when delivered at the addresses specified in this Section 11.8; provided that
any notice given pursuant to Section 2 hereof shall be effective only upon
receipt.

         Section 11.9 Counterparts. This Agreement may be executed in any number
of counterpart signature pages, and by the different parties on different
counterparts, each of which when executed shall be deemed an original but all
such counterparts taken together shall constitute one and the same instrument.

         Section 11.10 Successors and Assigns. This Agreement shall be binding
upon the Borrower and its successors and assigns, and shall inure to the benefit
of each of the Banks and the benefit of their respective successors and assigns,
including any subsequent holder of any Note. The Borrower may not assign any of
its rights or obligations under any Credit Document without the written consent
of all of the Banks.

         Section 11.11 Participants and Note Assignees. Each Bank shall have the
right at its own cost to grant participations (to be evidenced by one or more
agreements or certificates of participation) in the Loans made and/or Revolving
Credit Commitments held by such Bank at any time and from time to time, and to
assign its rights under such Loans or the Note evidencing such Loans to a
federal reserve bank; provided that (i) no such participation or assignment
shall relieve any Bank of any of its obligations under this Agreement, (ii) no
such assignee or participant shall have any rights under this Agreement except
as provided in this Section 11.11, and (iii) the Agent shall have no obligation
or responsibility to such participant or assignee, except that nothing herein is
intended to affect the rights of an assignee of a Note to enforce the Note
assigned. Any party to which such a participation or assignment has been granted
shall have the benefits of Section 2.11 and Section 9.3, but shall not be
entitled to receive any greater payment under either such Section than the Bank
granting such participation would have been entitled to receive in connection
with the rights transferred. Any agreement pursuant to which any Bank may grant
such a participating interest shall provide that such Bank shall retain the sole
right and responsibility to enforce the obligations of the Borrower hereunder,
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such participation
agreement may provide that such Bank will not agree to any modification,
amendment or waiver of this Agreement that would (A) increase any Revolving
Credit Commitment of such Bank if such increase would also increase the
participant's obligations, (B) forgive any amount of or postpone the date for
payment of any principal of or interest on any Loan or of any fee payable
hereunder in which such participant has an interest or (C) reduce the stated
rate at which interest or fees in which such participant has an interest accrue
hereunder.

         Section 11.12 Assignment of Commitments by Banks. Each Bank shall have
the right at any time, with the written consent (except in the case of an
assignment to (i) an Affiliate of such Bank, or (ii) another Bank) of the
Borrower and Agent (which consent shall not be unreasonably withheld), to assign
all or any part of its Revolving Credit Commitment (including the same
percentage of its Note and outstanding Loans) to one or more other Persons;
provided that such assignment is in an amount of at least $10,000,000 or the
entire Revolving Credit Commitment of such Bank, and if such assignment is not
for such Bank's entire Revolving Credit Commitment then such Bank's Revolving
Credit Commitment after giving effect to such assignment shall not be less than
$10,000,000; and provided further that neither the consent of the Borrower nor
of the Agent shall be required for any Bank to assign all or part of its
Revolving Credit Commitment to any Affiliate of the assigning Bank. Each such
assignment shall set forth the assignee's address for notices to be given under
Section 11.8 hereof hereunder and its designated Lending Office pursuant to
Section 9.4 hereof. Upon any such assignment, delivery to the Agent of an
executed copy of such assignment agreement and the forms referred to in Section
11.1 hereof, if applicable, and, except in the case of an assignment to an
Affiliate of the assigning Bank, the payment of a $3,500 recordation fee to the
Agent, the assignee shall become a Bank hereunder, all Loans and the Revolving
Credit Commitment it thereby holds shall be governed by all the terms and
conditions hereof and the Bank granting such assignment shall have its Revolving
Credit Commitment, and its obligations and rights in connection therewith,
reduced by the amount of such assignment; provided, however, in the event a Bank
assigns all of its Revolving Credit Commitment to an Affiliate or at the request
of the Borrower, pursuant to Section 11.13(iii), no recordation fee shall be
required hereunder. Notwithstanding any other provision set forth in this
Agreement, any Bank may at any time create a security interest in all or any
portion of its rights under this Agreement (including, without limitation, the
Loans owing to it and the Note held by it) in favor of any Federal Reserve Bank
in accordance with Regulation A of the Board of Governors of the Federal Reserve
System.

         Section 11.13 Amendments. Any provision of the Credit Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by (a) the Borrower, (b) the Required Banks, and (c) if the rights or
duties of the Agent are affected thereby, the Agent; provided that:

                   (i) no amendment or waiver pursuant to this Section 11.13
              shall (A) increase any Commitment of any Bank without the consent
              of such Bank or (B) reduce the stated rate at which interest or
              fees accrue or reduce the amount of or postpone any fixed date for
              payment of any principal of or interest on any Loan or of any fee
              payable hereunder without the consent of each Bank; and

                   (ii) no amendment or waiver pursuant to this Section 11.13
              shall, unless signed by each Bank, change this Section 11.13, or
              the definition of Required Banks, or affect the number of Banks
              required to take any action under the Credit Documents.

         If the Borrower requests an amendment to this Agreement which requires
the approval of all of the Banks and one of the Banks (a "Replaceable Bank")

<PAGE>   47

may propose that another bank which is reasonably acceptable to the Agent (a
"Replacement Bank") be substituted for and replace the Replaceable Bank for
purposes of this Agreement. If a Replacement Bank is so substituted for the
Replaceable Bank, the Replaceable Bank shall enter into an assignment agreement
with the Replacement Bank, the Borrower and the Agent to assign and transfer to
the Replacement Bank, the Replaceable Bank's Commitment hereunder, which shall
provide, among other things, for the payment of all Obligations owing to the
Replaceable Bank; provided, however, if a Replacement Bank cannot be found, then
the Borrower may elect to take out the Replaceable Bank and reduce the facility
accordingly by making a prepayment in the amount of such Replaceable Bank's
outstanding Loans plus all accrued and unpaid interest thereon and all fees and
all other Obligations due and owing to the Replaceable Bank on the date of
replacement. Notwithstanding anything to the contrary contained herein, in no
event shall the Agent be a Replaceable Bank.

reference only and shall not affect the construction of this Agreement.

         Section 11.15 Legal Fees, Other Costs and Indemnification. The Borrower
agrees to pay all reasonable costs and expenses of the Agent in connection with
the preparation and negotiation of the Credit Documents, including, without
limitation, the reasonable fees and disbursements of counsel to the Agent, in
connection with the preparation and execution of the Credit Documents and any
amendment, waiver or consent related hereto, whether or not the transactions
contemplated herein are consummated. The Borrower further agrees to indemnify
each Bank, the Agent, and their respective Affiliates, directors, agents,
officers and employees, against all losses, claims, damages, penalties,
judgments, liabilities and expenses (including, without limitation, all expenses
of litigation or preparation therefor, whether or not the indemnified Person is
a party thereto) which any of them may incur or reasonably pay arising out of or
relating to any Credit Document or any of the transactions contemplated thereby
or the direct or indirect application or proposed application of the proceeds of
any Loan other than those which arise from the gross negligence or willful
misconduct of the party claiming indemnification. The Borrower, upon demand by
the Agent or a Bank at any time, shall reimburse the Agent or Bank for any
reasonable legal or other expenses incurred in connection with investigating or
defending against any of the foregoing except if the same is directly due to the
gross negligence or willful misconduct of the party to be indemnified.

         Section 11.16 Entire Agreement. The Credit Documents constitute the
entire understanding of the parties thereto with respect to the subject matter
thereof and any prior or contemporaneous agreements, whether written or oral,
with respect thereto are superseded thereby.

         Section 11.17 Construction. The parties hereto acknowledge and agree
that neither this Agreement nor the other Credit Documents shall be construed
more favorably in favor of one than the other based upon which party drafted the
same, it being acknowledged that all parties hereto contributed substantially to
the negotiation of this Agreement and the other Credit Documents.

                                                                   March 9, 2001

         For Value Received, the undersigned, NRG Energy, Inc., a Delaware
corporation (the "Borrower"), promises to pay to the order of
_______________________________(the "Bank") on the Termination Date of the
hereinafter defined Credit Agreement, at the principal office of ABN AMRO Bank
N.V., Chicago Branch, in Chicago, Illinois, in U.S. Dollars, the aggregate
unpaid principal amount of all Loans made by the Bank to the Borrower pursuant
to the Credit Agreement, together with interest on the principal amount of each
Loan from time to time outstanding hereunder at the rates, and payable in the
manner and on the dates, specified in the Credit Agreement.

         The Bank shall record on its books or records or on a schedule attached
to this Note, which is a part hereof, each Loan made by it pursuant to the
Credit Agreement, together with all payments of principal and interest and the
principal balances from time to time outstanding hereon, whether the Loan is a
Base Rate Loan or a Eurocurrency Loan, the interest rate and Interest Period
applicable thereto, provided that prior to the transfer of this Note all such
amounts shall be recorded on a schedule attached to this Note. The record
thereof, whether shown on such books or records or on a schedule to this Note,
shall be prima facie evidence of the same, provided, however, that the failure
of the Bank to record any of the foregoing or any error in any such record shall
not limit or otherwise affect the obligation of the Borrower to repay all Loans
made to it pursuant to the Credit Agreement together with accrued interest
thereon.

         This Note is one of the Notes referred to in the 364-Day Revolving
Credit Agreement dated as of March 9, 2001, among the Borrower, ABN AMRO Bank
N.V., as Agent, and the Banks party thereto (the "Credit Agreement"), and this
Note and the holder hereof are entitled to all the benefits provided for thereby
or referred to therein, to which Credit Agreement reference is hereby made for a
statement thereof. All defined terms used in this Note, except terms otherwise
defined herein, shall have the same meaning as in the Credit Agreement. This
Note shall be governed by and construed in accordance with the internal laws of
the State of New York.

         Prepayments may be made hereon and this Note may be declared due prior
to the expressed maturity hereof, all in the events, on the terms and in the
manner as provided for in the Credit Agreement.

         The Borrower hereby waives demand, presentment, protest or notice of
any kind hereunder.
