PART I 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 in the United States and internationally. NRG Energy believes it is one of the three largest independent power generation companies in the world, measured by its net ownership interest in power generation facilities. As of December 31, 2001, NRG Energy owned all or a portion of 76 generation projects, including projects under construction, that have a total generating capacity of 38,388 megawatts (MW). Its current net ownership interest in those projects is 24,357 MW, of which 19,077 MW are located in the United States. As the following table illustrates, NRG Energy has grown significantly during recent years, primarily as a result of its success in acquiring domestic power generation facilities:

YEAR ENDED DECEMBER 31, -------------------------------------------------- 1997 1998 1999 2000 2001 CAGR ------- ------- -------- -------- -------- ---- (IN THOUSANDS, EXCEPT MW DATA) Net Ownership Interest (In MW at end of period)(1)..... 2,637 3,300 10,990 15,007 24,357 74% Operating Income................ $18,109 $57,012 $109,520 $573,073 $714,822 151% EBITDA(2)....................... $39,790 $82,711 $161,516 $692,548 $954,835 121% Net Income...................... $21,982 $41,732 $ 57,195 $182,935 $265,204 86%
- --------------- (1) Includes projects under construction; MW under construction for the years 1997, 1998, 1999, 2000 and 2001 were 616, 284, 252, 747, and 4,775, respectively. (2) EBITDA is the sum of income (loss) before income taxes, interest expense (net of capitalized interest) and depreciation and amortization expense. EBITDA is a measure of financial performance not defined under generally accepted accounting principles, which should not be considered in isolation or as a substitute for net income, cash flows from operations or other income or cash flow data prepared in accordance with generally accepted accounting principles or as a measure of a company's profitability or liquidity. In addition, EBITDA as calculated by NRG Energy may not be comparable to similarly titled measures presented by other companies, and therefore could be misleading because all companies and analysts do not calculate it in the same fashion. NRG Energy has experienced significant growth in the last year, expanding from 15,007 MW of net ownership interests in power generation facilities (including those under construction) as of December 31, 2000, to 24,357 MW of net ownership interests as of December 31, 2001. NRG Energy has a well diversified portfolio in terms of location, fuel and dispatch mode. NRG Energy is organized into four regionally-based divisions: NRG North America, based in Minneapolis, Minnesota; NRG Europe, based in London; NRG Asia-Pacific based in Brisbane, Australia and NRG Latin America, based in Miami, Florida. Most of NRG Energy's North American projects are grouped under regional holding companies corresponding to their domestic core market. 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 a regional basis. NRG Energy's international power generation projects are managed as three distinct markets, Asia-Pacific, Europe and Other Americas. 1

In addition to NRG Energy's power generation projects, NRG Energy also has interests in district heating and cooling systems and steam transmission operations. 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. However, in the short term, recognizing market conditions, NRG Energy anticipates that its growth level will be lower than in recent years. As of December 31, 2001, NRG Energy had signed agreements to acquire an additional 3,571 MW of net ownership interest in existing generation projects. Currently, NRG Energy has scheduled expansion, repowering or greenfield generation projects that would add 5,308 MW of net ownership interest. 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. By linking NRG Energy's capabilities and access to fuel supplies with its power marketing and risk management expertise, NRG Energy believes that it effectively manages risk, and has secured and will continue to secure favorable pricing for its fuel purchases and power sales. NRG Energy was incorporated as a Delaware corporation on May 29, 1992. Its 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. 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 Energy), 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 Energy. As of December 31, 2000, Xcel Energy indirectly 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 Energy directly owns six utility subsidiaries that serve electric and natural gas customers in 12 states. Xcel Energy also owns or has interest in a number of nonregulated businesses, the largest of which is NRG Energy. In March 2001, NRG Energy completed a public offering of 18.4 million shares of its common stock. Following this offering, Xcel Energy indirectly owns a 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. XCEL ENERGY EXCHANGE OFFER In February 2002, Xcel Energy announced its intention to commence an exchange offer by which Xcel Energy would acquire all of the outstanding publicly held shares of NRG Energy. In its announcement, Xcel Energy stated its intention to close the transaction in April 2002, and stated that NRG Energy shareholders would receive 0.4846 shares of Xcel Energy common stock in a tax-free exchange for each outstanding share of NRG Energy common stock. After completion of the merger, NRG Energy would be an indirect, wholly owned subsidiary of Xcel Energy. NRG Energy's debt and other obligations will continue to be the sole obligation of NRG Energy. On March 13, 2002, Xcel Energy filed a registration statement on Form S-4 with the Securities and Exchange Commission and commenced the exchange offer. In its registration statement, Xcel Energy stated that, if the exchange offer and merger are completed, its plans for NRG Energy in 2002 include: infusing an additional $300 million of equity into NRG Energy, in addition to an initial loan of $300 million recently made to NRG Energy; slowing NRG Energy's growth in megawatt capacity and the possible sale of $1.9 billion of existing generating assets; canceling or deferring approximately $1.6 billion of planned projects; and beginning the process of selling unassigned turbines and deferring installment of additional unassigned turbines. 2

In addition, Xcel Energy stated in its registration statement that if the offer and merger are completed and its plans for NRG Energy are implemented, it expects to reduce NRG Energy's business development activities and administrative and general costs, with annual estimated cost savings of approximately $45 million, and to capture infrastructure savings by consolidating trading and marketing organizations, where appropriate. MARKET OPPORTUNITY The power industry is one of the largest industries in the world, accounting for approximately $225 billion in annual revenues and approximately 830,000 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. Outside of the United States, 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 has been to be a leading global generation company with a top three position in selected core markets, which provides superior performance to all stakeholders. Central to this vision is the development and management of diverse regional portfolios of competitive power generating facilities. This diversity incudes geographic location, fuel type and dispatch profile. Currently, approximately 78% of NRG Energy's net MW of generation in operation and under construction is located in the United States in five core markets: Northeast, South Central and West Coast regions and the recently added North Central and Mid Atlantic regions. 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 and periods of constrained availability of generating capacity, fuels and transmission. NRG Energy's primary focus has been on generation assets powered primarily by natural gas, coal, oil and to a lesser extent landfill gas, hydro, refuse derived fuel and biomass technologies. NRG Energy's strategy is to capitalize on its acquisition, development, construction and operating skills to build a balanced portfolio of power generation assets. NRG Energy intends to implement this strategy by continuing a disciplined acquisition program, recognizing current market conditions. NRG Energy believes that its facility operations and engineering expertise, fuel and environmental strategies, labor and governmental relations expertise, legal and financial skills give it a competitive advantage in the independent power market. NORTH AMERICAN POWER GENERATION While NRG Energy expects the North American power generation market to continue to evolve from a regulated, utility dominated market based upon cost-of-service pricing to an independent power generation market based on competitive market pricing, the pace of this evolution slowed in 2001 as a result of the energy crisis in California, and more recently, the Enron bankruptcy. Most domestic generation capacity is still utility owned and subject to cost-of-service regulation. NRG Energy expects the evolution to continue as non-regulated power generators build new capacity to meet demand, but, in view of current market and forward 3

prices, and the credit and liquidity constraints reported by many competitive power producers in recent months, NRG Energy expects such new capacity development to be less than has been forecast. 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 and Mid Atlantic regions are managed from its Minneapolis headquarters and Wilmington, Delaware offices, respectively. 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 a regional basis. NORTHEAST REGION As of December 31, 2001, NRG Energy owned approximately 7,676 MW of net generating capacity (including projects under construction) in the Northeast United States and Canada, primarily in New York, 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 New England Power Pool (NEPOOL). SOUTH CENTRAL REGION As of December 31, 2001, NRG Energy owned approximately 4,716 MW of net generating capacity (including projects under construction) in the South Central United States, primarily in Louisiana, Oklahoma, Texas and Mississippi. NRG Energy's South Central generating assets consist primarily of its net ownership of 1,947 MW of power generation facilities in New Roads, Louisiana (which are referred to as the Cajun facilities) that were acquired in March 2000 and the recently completed Big Cajun Peakers (238 MW). The South Central region also includes the Sterlington (202 MW), McClain (400 MW), Batesville (837 MW), Mustang (122 MW), and Sabine River (210 MW) generating facilities. In addition, the Bayou Cove (320 MW) and Brazos Valley (633 MW) facilities are under construction. The construction of the following additional facilities with a net generating capacity of 2,680 MW is planned: Kaufman (545 MW), Batesville expansion (292 MW), Big Cajun II, Unit 4 (675 MW) and Pike (1,168 MW). WEST COAST REGION As of December 31, 2001, NRG Energy owned approximately 1,596 MW of net generating capacity on the West Coast of the United States, primarily California and Nevada. NRG Energy's West Coast generation assets consist primarily of a 50% interest in West Coast Power LLC (West Coast Power), a 58% interest in the Crockett Cogeneration facility (138 MW)and a 50% interest in the Saguaro generation facility (53 MW). In May 1999, Dynegy Power Corporation (Dynegy) and 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 is comprised of the El Segundo Generating Station (510 MW), the Long Beach Generating Station (265 MW), the Encina Generating Station (483 MW) and 17 combustion turbines in the San Diego area (127 MW). 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. 4

NORTH CENTRAL REGION As of December 31, 2001, NRG Energy owned approximately 3,706 MW of net generating capacity in the north central United States, primarily in Illinois, Missouri and Michigan. NRG Energy's North Central portfolio includes the 640 MW simple cycle, gas-fired Audrain power generation facility, located in Vandalia, Missouri. In August 2001, NRG Energy purchased a project portfolio from Indeck Energy Services which includes the Rockford I (342 MW) and Rockford II (171 MW) Energy Centers, located 75 miles west of Rockford, Illinois. Rockford II is currently under construction with commercial operation expected in June 2002. Other North Central projects in operation include Rocky Road (175 MW), Morris Cogeneration (23 MW) and Cadillac Renewable Energy (19 MW). Two additional projects in Illinois currently under construction will add 1,168 MW each to NRG Energy's North Central portfolio. Kendall is estimated to be in commercial operation in May 2002, and Nelson in the third quarter of 2003. MID-ATLANTIC REGION As of December 31, 2001, NRG Energy owned approximately 1,199 MW of net generating capacity in the Mid-Atlantic region of the United States, primarily Delaware, Maryland, Ohio and Pennsylvania. In June 2001, NRG Energy completed the acquisition of approximately 1,081 MW of operational generating facilities from Conectiv. In January 2002, NRG Energy closed the acquisition of the Commonwealth Atlantic generating facility (188 MW) and the James River generating facility (55 MW) from Edison Mission and expects to close on the FirstEnergy acquisition of approximately 2,535 MW of generating facilities during the second quarter of 2002. 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 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 has taken advantage of opportunities to invest in attractive projects in international markets. 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. 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. ASIA PACIFIC NRG Energy is one of the largest competitive power producers in Australia and, with its 2001 acquisitions in Taiwan and India, now has a net ownership interest of 2,297 MW, as of December 31, 2001, in power generation facilities. EUROPE NRG Energy is a participant in the competitive power generation markets in Germany, the Czech Republic, the United Kingdom, and Hungary. As of December 31, 2001, NRG Energy has a net ownership interest of 1,854 MW in power generation facilities (including projects under construction) in Europe. During 2001, NRG Energy increased its ownership interest in the MIBRAG and Schkopau projects in April 2001, both of which are located in Germany and completed its acquisition of the Csepel facility located in Hungary in June 2001. 5

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. As of December 31, 2001, NRG Energy has ownership of 1,107 MW in Latin America. NRG Energy currently owns and operates 270 MW of hydro and thermal electric operating assets in Bolivia and is the second largest generator in that country. Similarly, NRG Energy owns and operates 111 MW of hydro and thermal electric operating assets in Peru. NRG Energy owns a 99% interest in a 156 MW hydro facility under construction in Brazil set to enter commercial operation in the third quarter 2002. In addition, NRG Energy recently formed a partnership venture with Petrobras Brazileros SA, the large state owned Brazilian oil company, to construct, own and operate a 1,040 MW gas-fired thermal facility in which it will own a 50% share. The TermoRio Project, currently under construction, is expected to enter full commercial operations in March 2004. ALTERNATIVE ENERGY NRG Energy provides alternative energy through NEO Corporation (NEO), one of the largest landfill gas generation companies in the United States, and NRG Resource Recovery, which processes municipal solid waste as fuel used to generate power. NEO CORPORATION NEO is a wholly owned subsidiary of NRG Energy that was formed to develop 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 distributed generation and peaking facilities and the acquisition of small hydroelectric projects. NEO owns and operates 31 landfill gas collection systems and has 46 MW of net ownership interests in related electric generation facilities utilizing landfill gas as fuel. NEO also has 42 MW of net ownership interests in 18 hydroelectric facilities and 109 MW of net ownership interests in seven distributed generation facilities. The company's operations are located primarily in the east and west coast regions of the United States. NEO derives a substantial portion of its income as a result of the generation of Section 29 tax credits, which, for 2001, totaled $48.6 million. The existing tax law authorizing these credits is scheduled to expire after 2007. RESOURCE RECOVERY FACILITIES NRG Energy's Resource Recovery business is focused on owning and operating alternative fuel/"green power" generation and fuels processing projects. The alternative fuels currently processed and combusted are municipal solid waste (MSW), of which more than 90% is processed into refuse derived fuel (RDF), urban wood waste (pallets, clean construction debris, etc.), forest industry waste wood (bark, sawmill waste, tree trimmings, etc.), agricultural waste (walnut shells, olive pits, peanut shells, etc.), and non-recyclable waste paper and compost. Processing and recovery for generation into electricity and other products is an environmentally superior method of waste management when compared to adding to existing or creating new landfills. NRG Energy's Resource Recovery business has MSW processing capacity of over 4,000 tons per day and generation capacity of 35 MW, of which its net ownership interest is 26 MW. NRG Energy's Resource Recovery business owns and operates MSW processing and/or generation facilities in Maine and Minnesota. This business also owns and operates a biomass fired generation facility in Florida and a wood processing facility in Georgia, which supplies a portion of the biomass fuel to the power plant in Florida. In addition to the fuels processing and generation portfolio, Resource Recovery owns and operates several mono-ash landfills that receive ash from the biomass and waste-to-energy power plants that are owned and operated. Resource Recovery also owns and operates NRG Processing Solutions that includes thirteen composting and biomass fuel processing sites in Minnesota of which three sites are permitted to operate as MSW transfer stations. A majority of Resource Recovery's facilities are under long-term contract for either the fuel processing and/or its generation capacity. 6

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 1,641 MWt, of which its net ownership interest is 1,514 MWt. NRG Energy owns and operates, through its holding company NRG Thermal Corporation, five district heating and cooling systems in Minneapolis, Minnesota, San Francisco, California, Pittsburgh, Pennsylvania, Harrisburg, Pennsylvania and San Diego, California. These systems provide steam heating to approximately 600 customers and chilled water to 90 customers. In addition, NRG Energy's thermal division operates five projects that serve industrial/government customers with high-pressure steam and hot water. NRG Thermal also owns and operates an 88 MW combustion turbine peaking generation facility and an 18 MW coal-fired cogeneration facility in Dover, Delaware. 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 markets energy and energy related commodities, including electricity, natural gas, oil, coal and emission allowance credits. By using internal resources to acquire fuel and market electricity, NRG Energy believes 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, North Central and Mid Atlantic 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 allowance credits needed to operate these facilities. NRG Energy is very disciplined in its approach to power marketing risk management. 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. Accordingly, NRG Energy has established counter-party concentration limits and portfolio VaR limits. 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 attempts to balance its fixed-price physical and financial purchases and sales commitments in terms of contract volumes and the timing of performance and delivery obligations. However, uncovered market positions are taken within guidelines established by the board of directors of NRG Power Marketing. Contracts for the transmission and transportation of these commodities are also authorized, as necessary, in order to meet physical delivery requirements and obligations. 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). 7

- 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 strives to mitigate variability in its earnings by having approximately 50% of its capacity contracted for under contracts with lengths of 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. 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. SIGNIFICANT CUSTOMERS During 2001, NRG Energy derived approximately 40.5% of its 2001 revenues from majority owned operations from two customers: New York Independent System Operator (26.7%) and Connecticut Light and Power Company (13.8%). 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%). SEGMENT INFORMATION For financial information on NRG Energy's operations on a geographical and on a segment basis, see Item 8 -- Note 18 to the Consolidated 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 industries, 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. NRG Energy's approach to plant management emphasizes the operational autonomy of its individual plant managers and staff to identify and resolve operational 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. SIGNIFICANT ASSET AND BUSINESS ACQUISITIONS GRANITE POWER PARTNERS In January 2001, NRG Energy purchased from LS Power LLC a 5,339 MW portfolio of operating projects and projects in construction and advanced development that are located primarily in the north central 8

and south central United States. Approximately 3,295 MW are currently in operation or under 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. BATESVILLE In March 2001, NRG Energy purchased from Cogentrix the remaining 430 MW or 51.37% interest, in a 837 MW natural gas-fired combined-cycle plant in Batesville, Mississippi.

OTHER PROJECTS During fiscal year 2001, NRG Energy also acquired interests in projects in Taiwan, India, Peru and the State of Nevada. SIGNIFICANT EQUITY INVESTMENTS The following are the more significant equity investments included in NRG Energy's Power Generation Segment. MIBRAG NRG Energy indirectly purchased a 33 1/3% interest in the equity of Mitteldeutsche Braunkohlengesellschaft mbH (MIBRAG) in 1994 for $10.6 million. In April 2001, NRG Energy purchased from PowerGen its 33.3% interest in MIBRAG Bv for $35.3 million which was repaid by the project company in June 2001. By acquiring PowerGen's interest in MIBRAG, and following MIBRAG's buy back of the shares, NRG Energy acquired from PowerGen, NRG Energy increased its ownership of MIBRAG from 33.3% to 50%. The Washington Group International, Inc., MIBRAG's other shareholder owns the remaining 50% of MIBRAG. 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 115 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 10

ENVIA the regional energy provider. MIBRAG's lignite mine operations include Profen 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 parties have reached a settlement, pending approval by the European Union. The settlement is not expected to have a material adverse impact on MIBRAG's operations. 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 Enertrade, a government owned entity, and to Boyne Smelters Limited. Pursuant to an interconnection and power pooling agreement, Enertrade is obligated to accept all electricity generated by the facility, subject to merit order dispatch, for an initial term of 35 years. Enertrade 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, Enertrade pays the facility owners both a capacity and an energy charge. The capacity charge is designed to cover the projected fixed costs allocable to Enertrade, 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 are 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. ENERGY CENTER KLADNO The Energy Center Kladno project, located in Kladno, the Czech Republic consists of two 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 and thermal energy to a nearby industrial complex and to a municipal heating company. The second phase was the expansion of the existing facility, which started commercial operation 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/oil-fired, facility acceptance was awarded in December 2001. The original project is owned by Energy Center Kladno, a Czech limited liability company in which NRG Energy owns a 44.5% interest. The expansion is held separately through ECK Generating, a Czech limited liability company in which NRG Energy owns a 44.5% interest. 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 recommis- 11

sioned 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 Enertrade under which Enertrade 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 Enertrade, 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 DEVELOPMENTS LTD Energy Developments Limited, a publicly traded company listed on the Australian Stock Exchange, owns and operates approximately 357 MW of generation with 77% of that generation located 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 represented approximately 29.1% ownership interest in Energy Developments. Since the acquisition NRG Energy's holding has been diluted to 26.3%. 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, NRG Energy is entitled to nominate under the terms of the agreement with Energy Developments. In either of those circumstances, the preference shares can be converted at the option of the owner to common shares on a share-for-share basis. 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 non-NRG facilities such as 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. 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, industrial customers and other generators. 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. Energy prices in the Victoria region of the National Electricity Market of Australia into which the Loy Yang facility sells its power have been significantly lower than NRG Energy expected when it acquired its interest in the facility. Prices improved during 2001 producing a 14% increase in revenue improvement over the prior year. Despite this improvement, a significant unplanned outage, beginning in late December 2001 and expected to last until April 2002, will result in a reduction in 2002 revenues and cash flows, and may cause the Loy Yang project company to fail its required coverage ratios under its loan agreements during the next 12 months, 12

which would constitute an event of default. In the case of default, the project company's lenders would be allowed to accelerate the project company's indebtedness. The ultimate financial impact of the outage is subject to continuing investigation, and is also subject to several events including; the receipt and timing of insurance proceeds, the cost and timing of repairs to the damaged unit, the potential installation of a replacement unit while repairs are carried out to the original unit and electricity market conditions. Management is actively pursuing each of these options to mitigate the impact of the outage. However, in the event all factors are unfavorable, NRG Energy may be required to infuse equity or write-off all or a portion of its $250 million investment in this project as a result of such acceleration. In its current circumstances, Loy Yang Power is prohibited by its loan agreements from making equity distributions to the project owners. 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 Energy's existing investment in Loy Yang Power is not known at the date of this report. WEST COAST POWER In May 1999, Dynegy and NRG Energy formed West Coast Power LLC (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 San Diego Combustion Turbines). 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.

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. The Encina Generating Station was purchased from San Diego Gas & Electric during May 1999, at a purchase price of $283.2 million. San Diego Combustion Turbines: The San Diego 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 is expected to be permitted by the third quarter of 2003.

NRG SOUTH CENTRAL GENERATING LLC In March 2000, the South Central 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. NRG South Central Generating LLC, an indirect wholly-owned subsidiary of NRG Energy, Inc, through its wholly-owned subsidiaries, Louisiana Generating LLC (Louisiana Generating), NRG New Roads Holdings LLC, NRG Sterlington Power LLC, Big Cajun I Peaking Power LLC (Big Cajun 1 Peakers), NRG Sabine River Works GP LLC, NRG Sabine River Works LP LLC and NRG Bayou Cove LLC owns approximately 2,679 MW of net electric generating capacity as of December 31, 2001 (including projects under construction). 15

Through its subsidiaries, Louisiana Generating and Big Cajun 1 Peakers, NRG South Central owns the Big Cajun I and Big Cajun II generating facilities in New Roads, Louisiana (the Cajun facilities). The Cajun facilities consist of 100% ownership of four gas-fired intermediate/peaking power generation units which NRG Energy collectively refers to as Big Cajun I. Two of these units were completed and commenced commercial operation in May and June 2001. The Cajun facilities also include 100% interest of two coal-fired, base-load power generation units, and a 58% interest in a third coal-fired, base load unit, which NRG Energy refers to collectively as Big Cajun II. The Cajun facilities were acquired through a competitive bidding process following a Chapter 11 bankruptcy filing by Cajun Electric Power Cooperative, Inc., a non-profit Louisiana electric membership cooperative corporation. Cajun Electric sold wholesale energy and capacity generated by the Cajun facilities to its cooperative members for more than 20 years under long-term, all-requirements power supply agreements. 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. In March 2000, NRG South Central formed NRG New Roads Holdings LLC (New Roads) to hold certain assets that were acquired in conjunction with the purchase of the Cajun facilities but which are not necessary for the operation of the Cajun facilities. NRG Sterlington Power LLC (Sterlington), which was acquired by NRG Energy and contributed to NRG South Central in August 2000, was formed for the purpose of developing, constructing, owning and operating an approximately 202 MW simple cycle gas peaking facility in Sterlington, Louisiana. Louisiana Generating has a right of first refusal on any sale of capacity or energy by Sterlington. In December 2000, NRG Sabine River Works LP and NRG Sabine River Works GP acquired, respectively, a 49% limited partnership interest and a 1% general partnership interest in SRW Cogeneration Limited Partnership, that owns and operates an approximately 420 MW natural gas-fired cogeneration plant at the DuPont Company's Sabine River Works petrochemical facility near Orange, Texas. Subsidiaries of Conoco, Inc. own the other 50% interest in SRW Cogeneration Limited Partnership. Commercial operation of the plant commenced in November 2001. 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 L390 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 L235 million (approximately U.S. $374 million at the time of acquisition) for the costs of the acquisition and L90 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. Prices for power in the wholesale electricity market of England and Wales have decreased since the acquisition date due to new trading rules that are expected to come into effect and increase competition in this market. 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 16

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. Since that original acquisition, NRG Energy has also announced that it will undertake a refurbishment of its 240 MW Playford Power Station, being one of the two coal-fired plants that form the central part of the Flinders business. GRANITE POWER PARTNERS NRG Energy has acquired, in two separate transactions a 5,339 MW portfolio of operating projects and projects in construction and advanced development from LS Power, LLC and Cogentrix for a total cost of approximately $830 million. Through 2005, NRG 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. Batesville: NRG Energy, through subsidiaries acquired approximately 100% ownership of a natural gas-fired combined-cycle electric generating facility with a design capacity of approximately 837 megawatts located in Batesville, Mississippi.

Additionally, a 292 MW expansion scheduled for operation in 2005 is currently in development. Mustang: NRG Energy acquired a 25% ownership interest in an approximately 122 MW electric generating facility located in Texas. The facility sells its energy under a long-term power purchase agreement. Kendall: Scheduled to be commercially operable in the second quarter 2002, the Kendall facility located just south of Chicago, Illinois will generate approximately 1,168 MW of electric power utilizing combined cycle gas turbines. Tolling agreements with Dynegy and Minnesota Power are in place for 870 MW with the remaining generation available for merchant markets. Additionally, a 584 MW expansion scheduled for operation in 2006 is currently in development. Pike: Construction began in February 2002 for a 1,168 MW natural gas fired facility located near McComb, Mississippi. This facility will use combined cycle gas turbines and is scheduled to be commercially operable in 2003. Nelson: Scheduled to be commercially operable in 2003, the Nelson facility to be located just west of Chicago, Illinois will generate approximately 1,168 MW of electric power utilizing combined cycle gas turbines. 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% participation 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. 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. In April 2001, NRG Energy acquired the remaining 50% of Saale Energie GmbH for $37.3 million which effectively increased NRG Energy's participation interest in Schkopau to 41.9% totaling 400 MW. 17

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. In June 2001, NRG Energy increased its interest in COBEE as part of a large portfolio acquisition of assets. 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. CSEPEL The Csepel facility is a 389 MW gas-fired power plant and a 116 MW thermal power plant, both of which are located on Csepel Island in Budapest, Hungary. In June 2001, NRG Energy acquired a 100% interest in the Csepel project for $111.4 million. The Csepel facility was the first new independent power station in Hungary. Csepel commenced operations in November 2000. The Csepel facility has a signed 20-year purchase power agreement with MVM, the Hungarian state owned utility. At commercial operation the purchase power agreement was replaced with an annual administrative price set by the Hungarian Energy office and approved by the Economic Ministry. Since commercial operation, the administrative price followed in line with the purchase power agreement pricing. In addition, the fuel is supplied to Csepel through a 20-year "back to back" gas supply agreement. MIDATLANTIC In June 2001 NRG Energy acquired 1,081 MW of baseload electric generating plants from Delmarva Power and Light, a subsidiary of Wilmington, Delaware-based Conectiv. As part of the agreement, NRG entered into both short- and long-term purchase power contracts with Delmarva Power to provide energy and capacity for the Delmarva Peninsula. Under the long-term agreement, Conectiv is obligated to purchase 500 MW through 2005 at contracted prices. The 784 MW coal-fired Indian River Generating Station is located on the Delmarva Peninsula near Millsboro, Delaware. The Vienna Generating Station is a 170 MW oil-fired generating station located along the Nanticoke River in the town of Vienna, Maryland. Of the 1,711 MW coal-fired Conemaugh Generating Station, NRG acquired 64 MW. The plant is located on the Conemaugh River, approximately 60 miles east of Pittsburgh, Pennsylvania. NRG Energy also acquired 63 MW of the 1,711 MW coal-fired Keystone Generating Station, located approximately 50 miles east of Pittsburgh, Pennsylvania. INDECK In August 2001, NRG Energy acquired a 2,255 MW project portfolio from Indeck Energy Services, Inc. The portfolio primarily serves the Chicago, Illinois energy market. NRG Energy acquired full ownership in five projects in operation, construction and advanced development. The portfolio includes combined-cycle and peaking power plants that employ natural gas-fueled combustion technology. Operational facilities include the Rockford I and Ilion Energy Centers. Projects under construction and development include the Rockford II Energy Center, Bourbonnais I and II Energy Centers. Rockford I is a 342 MW simple cycle power generation plant designed to produce peaking electricity located in Rockford, Illinois. Power is contracted to ComEd under a long-term power sales agreement. Under 18

the agreement, ComEd delivers natural gas and the facility generates electricity to ComEd that amounts to a tolling arrangement. Ilion, located in central upstate New York, is a 60 MW combined cycle cogeneration plan. Ilion operates as a merchant power plant while selling its steam to Remington Arms Company. The Rockford II project is scheduled for commercial operation in 2002 while the Bourbonnais projects are planned for 2004 and 2005. HSIN YU ENERGY DEVELOPMENT CO. LIMITED During 2001, NRG Energy acquired approximately 60% ownership in Hsin Yu Energy Development Co. LTD for NT $1.6 billion (approximately $46.7 million at the date of acquisition). Hsin Yu is a Taiwan company that owns a 170 MW cogeneration facility located near Taipei. Hsin Yu is developing a 245 MW expansion of the facility and has rights to develop a 490 MW Greenfield project near Tainan. Hsin Yu sells power to industrial customer under short-term power purchase agreements and sells residual power to Tai Power. Hsin Yu secures gas supply through a 12-year contract with China Petroleum Corp. the state owned gas supplier. 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. FIRSTENERGY In November 2001, NRG Energy signed purchase agreements to acquire or lease four coal-fired generating facilities totaling approximately 2,535 MW and two ash disposal sites from subsidiaries of FirstEnergy Corporation. The four generating facilities are located in Ohio, along the shore of Lake Erie, and the approximately 376 MW Ashtabula facility in Ashtabula, Ohio, the approximately 249 MW Lake Shore facility in downtown Cleveland, the approximately 1,262 MW Eastlake facility near Cleveland and the approximately 648 MW Bay Shore facility near Toledo. NRG Energy is also acquiring all of the equity interests in Bay Shore Power Company, which is a subsidiary of FirstEnergy and the owner of a 136 MW petroleum coke-fired steam generating project on the Bay Shore facility site. The acquisition is expected to close in the second quarter of 2002. In connection with the acquisition of these facilities, NRG Energy also entered into a Transition Power Purchase Agreement with FirstEnergy, pursuant to which NRG Energy will supply to FirstEnergy approximately 95% of the output from the facilities through 2005. CONECTIV ASSETS In June and October 2001, NRG Energy extended purchase agreements that NRG Energy entered into with a subsidiary of Conectiv in January 2000 to acquire 794 MW of coal and oil-fired electric generating capacity and other assets in New Jersey and Pennsylvania, including an additional 66 MW of Conemaugh Generating Station and an additional 42 MW of the Keystone Generating Station. By their terms these purchase agreements became terminable by either party after February 28, 2002, and on April 1, 2002 NRG Energy exercised its right to terminate the agreements. 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 permits and approvals be obtained before siting a power plant, during the plants construction, and after it becomes fully operational. Throughout each phase of the project's implementation, all operations must be conducted in compliance with the terms specified in such permits and approvals. 19

NRG Energy strives to comply with the terms of all applicable laws, regulations, permits and licenses and believes that all of its ongoing operations are in material compliance with all such requirements. Even so, due to the promulgation of increasingly stringent regulatory requirements and/or local opposition to its projects, NRG Energy cannot presently assure its ability to obtain all future permits and approvals nor guarantee 100% regulatory compliance. In order to approach such levels of regulatory certainty, prohibitive expenditures could force projects to be abandoned, create the risk of expensive delays or materially impair project values. 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. 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. Accompanying such awareness is the requirement to achieve stringent emission limitations. NRG Energy believes that the nature and level of environmental regulation to which it is subject will become more stringent. Therefore, NRG Energy's policy is to integrate the consideration of potential environmental impacts into every decision it makes, and by doing so strive to improve its competitive advantage by meeting or exceeding environmental requirements pertaining to the management and operation of its assets. 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. In recent years, the independent power industry has been characterized by increased competition for asset purchases and development opportunities. In recent months there have been announcements from several of NRG Energy's competitors that they will be scaling back their growth plans and delaying construction expenditures. 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. 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. 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 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 20

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. EMPLOYEES At December 31, 2001, NRG Energy had 3,888 employees, approximately 496 of whom are employed directly by NRG Energy and approximately 3,392 of whom are employed by its wholly owned subsidiaries and affiliates. Approximately 1,825 employees are covered by bargaining agreements. NRG Energy has experienced no significant labor stoppages or labor disputes at its facilities.

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 in New York. NRG Energy disputed Fortistar's allegations and asserted numerous counterclaims, and in October 1999, NRG Energy, through a wholly-owned subsidiary, closed on the acquisition of the Oswego facility. In April and December 2000, NRG Energy filed summary judgment motions to dispose of the litigation. A hearing on these motions was held in February 2001 and certain of Fortistar's claims were dismissed. NRG Energy intends to continue to vigorously defend the suit and believes Fortistar's claims to be without merit. A trial date of May 13, 2002 has been set in respect of the remaining claims. NEW YORK ENVIRONMENTAL LITIGATION In January 2002 the New York Attorney General and the New York Department of Environmental Control (NYDEC) filed suit in the western district of New York against NRG Energy and Niagara Mohawk Power Corporation (Niagara Mohawk), the prior owner of the Huntley and Dunkirk facilities in New York. The lawsuit relates to physical changes made at those facilities prior to NRG Energy's assumption of ownership. The complaint alleges that these changes represent major modifications undertaken without the required permits having been obtained. 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, NRG Energy could be enjoined from operating the facilities if the facilities are found not to comply with applicable permit requirements. In July 2001, Niagara Mohawk Power Corporation filed a declaratory judgment action in the Supreme Court for the State of New York, County of Onondaga, against NRG Energy and its wholly-owned subsidiaries, Huntley Power LLC and Dunkirk Power LLC. Niagara Mohawk requests a declaration by the Court that, pursuant to the terms of the Assets Sales Agreement under which NRG Energy purchased the Huntley and Dunkirk generating facilities from Niagara Mohawk (the ASA), defendants have assumed liability for any costs for the installation of emissions controls or other modifications to or related to the Huntley or Dunkirk plants imposed as a result of violations or alleged violations of environmental law. Niagara Mohawk also requests a declaration by the Court that, pursuant to the ASA, defendants have assumed all liabilities, including liabilities for natural resource damages, arising from emissions or releases of pollutants from the Huntley and Dunkirk plants, without regard to whether such emissions or releases occurred before, on or after the closing date for the purchase of the Huntley and Dunkirk plants. NRG Energy has counterclaimed against Niagara Mohawk, and the parties have exchanged discovery requests. NYDEC OPACITY NOTICE OF VIOLATION NRG Energy became part of an opacity consent order as a result of acquiring its Huntley, Dunkirk and Oswego plants from Niagara Mohawk. At the time of financial close on these assets, a consent order was being negotiated between Niagara Mohawk and the NYDEC; it required Niagara Mohawk to pay a stipulated penalty for each opacity event at these facilities. On January 14, 2002, the NYDEC issued NRG Energy Notices of Violations (NOV) for opacity events which had occurred since the time NRG Energy assumed ownership of the Huntley, Dunkirk and Oswego generating stations. The NOVs allege that a total of 7,231 events had occurred where the average opacity during a six minute block of time had exceeded 20%. The NYDEC set the penalty associated with the NOVs at $900,000. 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 in November 2000 (Pamela R. Gordon v. Reliant Energy, Inc., et al. and Ruth Hendricks 26

v. Dynegy Power Marketing Inc., et al). NRG Energy has also been named in another suit filed in January 2001 in San Diego County and brought by three California water districts, as consumers of electricity (Sweetwater Authority v. Dynegy, Inc., et al.), and in two suits filed in San Francisco County, one 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.) and one brought by Pier 23 Restaurant as a class action (Pier 23 Restaurant v. PG&E Energy Trading, et al.). Certain NRG Energy affiliates in NRG Energy's West Coast power partnership with Dynegy (Cabrillo I and II, Long Beach Generation and El Segundo Power) have been named as defendants in a state court action in Los Angeles County (Bustamonte v. Dynegy, 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 Coordinating Council and otherwise. 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. These six civil actions brought against NRG Energy and other power generators and power traders in California have been consolidated and assigned to the presiding judge of the San Diego County Superior Court, and a pre-trial conference has been scheduled for March 2002. The plaintiffs in these six consolidated civil actions have filed a master amended complaint with the Superior Court of the State of California, County of San Diego. The plaintiffs reiterate the allegations contained in their complaints and allege that defendants' anti-competitive conduct damaged the general public and class members in an amount in excess of $1.0 billion. On March 20, 2002 the Attorney General of California filed at the Federal Energy Regulatory Commission a complaint against specific named generators and marketers (including Dynegy Power Marketing, Inc., which serves as the scheduling coordinator for certain NRG affiliates) and against "all other public utility sellers of energy and ancillary services into markets operated by the California Power Exchange and California Independent System Operator." The complaint alleges that defendants have violated FERC's grant of market-based rate authority by failing to file their rates, as required by Section 205(c) of the Federal Power Act and numerous FERC orders requiring the filing of transaction-specific information about defendants' sales and purchases at market-based rates. The plaintiff seeks injunctive relief to compel defendants' prospective compliance with Section 205 of the Federal Power Act, as well as refunds on behalf of California purchasers to the extent prior transactions are found to exceed just and reasonable price levels. On March 27, 2002, the Attorney General of California requested that Xcel, Inc., NRG Energy, Inc., Dynegy, Inc., Dynegy Power Marketing, Inc., and certain NRG affiliates agree to toll the statute of limitations for a threatened action under the Clayton Antitrust Act. The Attorney General has neither provided a draft complaint nor served an actual complaint, but the Company expects to see a draft complaint within the next several weeks. SHAREHOLDER LITIGATION On February 15, 2002, Xcel Energy announced its intention to commence an exchange offer to acquire all of the outstanding publicly held shares of NRG Energy. Following this announcement, nine separate but similar civil actions were filed in the Court of Chancery of the State of Delaware in and for New Castle County by owners of NRG Energy common stock, against Xcel Energy, NRG Energy and NRG Energy's directors. The complaints contain a number of allegations, but the basic claim is that Xcel proposes to acquire the remaining ownership of NRG Energy for inadequate consideration and without full and complete disclosure of all material information, in breach of defendants' fiduciary duties. The complaints request the court to enjoin the proposed transaction and, in the event the exchange offer is consummated, to award damages to plaintiffs. An NRG Energy stockholder has also filed a class action complaint challenging the transaction in a Minnesota state court against Xcel Energy, NRG Energy, and seven of the nine NRG Energy directors, alleging essentially the same charges. 27

ANCILLARY SERVICES On March 11, 2002, the Attorney General of California filed a civil complaint against NRG Energy, certain NRG Energy affiliates, Xcel Energy, Dynegy, Inc. and Dynegy Power Marketing, Inc., alleging antitrust violations in the ancillary services market. The complaint alleges that defendants repeatedly sold electricity generating capacity to the California ISO for use as a reserve and subsequently, and impermissibly, sold the same capacity into the "spot" market for wholesale power, unlawfully collecting millions of dollars. Similar complaints were filed against other power generators. The plaintiff seeks an injunction against further similar acts by the defendants, and also seeks restitution, disgorgement of all proceeds, including profits, gained from these sales, and certain civil penalties. 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.

ITEM 7 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2001 COMPARED TO THE YEAR ENDED DECEMBER 31, 2000 EARNINGS PER SHARE Earnings per share on a fully diluted basis for 2001 were $1.35, compared to $1.10 for 2000, an increase of $0.25 or approximately 22.7%. During the year 2001, earnings per share were adversely affected through additional dilution resulting from the issuance of 18.4 million shares of common stock in March 2001 and through the issuance and exercise of stock options throughout the year, as compared to 2000. NET INCOME Net income for 2001 was $265.2 million, compared to $182.9 million for 2000, an increase of $82.3 million or approximately 45.0%. Net income for 2001 increased by $82.3 million due to the factors described below. REVENUES AND EQUITY IN EARNINGS OF UNCONSOLIDATED AFFILIATES For the year ended December 31, 2001, NRG Energy had total revenues and equity earnings of $3.0 billion, compared to $2.2 billion for 2000, an increase of $850.7 million or approximately 39.4%. REVENUES FROM MAJORITY-OWNED OPERATIONS NRG Energy's operating revenues from majority-owned operations were $2.8 billion compared to $2.0 billion, an increase of $780 million or approximately 38.6%. Revenues from majority-owned operations for the year ended December 31, 2001, consisted primarily of power generation revenues from domestic operations of approximately $1.8 billion, operations in Europe of $490.9 million, Asia-Pacific $239.1 million and Other Americas $34.7 million, resulting in increases of $256.5 million, $293.2 million, $144.4 million and $34.4 million compared to 2000, respectively. In addition, NRG Energy recognized revenues from majority-owned operations from its alternative energy, thermal and other operations of approximately $79.5 million, $108.3 million and $10.9 million respectively, resulting in increases of $37.9 million, $20.5 million and a decrease of $6.9 million compared to 2000, respectively. The increase of $256.5 million related to NRG Energy's domestic power generation operations is due primarily to additional sales at NRG Energy's Mid Atlantic region facilities which were acquired in June 2001 from Conectiv and increased sales at NRG Energy's South Central region facilities which were primarily acquired in March 2000 from Cajun Electric and expanded with the acquisition of the Batesville facility from LS Power in January 2001 and completion of the Sterlington and Big Cajun 1 peaking facilities in 2001. The increase of $293.2 million related to NRG Energy's Europe power generation operations is due primarily to operations at Entrade, the Csepel facility in Hungary and Saale Energia in Germany (SEG). Entrade was acquired in November 2000, Csepel was acquired in June 2001 and SEG through an increase in ownership became consolidated in March 2001. The increase of $144.4 million related to NRG Energy's Asia-Pacific's power generation operations is due primarily to a full year of operations at the Flinders Power facilities which was acquired in August 2000 and to a lesser degree the addition of the Hsin Yu Development Company facilities in July 2001. The increase of $34.4 million related to NRG Energy's Other America's power generation operations is due primarily to the consolidation in 2001 of the COBEE and Bulo Bulo facilities which were previously accounted for under the equity method. EQUITY IN EARNINGS OF UNCONSOLIDATED AFFILIATES For the year ended December 31, 2001, NRG Energy had equity in earnings of unconsolidated affiliates of $210.0 million, compared to $139.4 million for 2000, an increase of $70.6 million or approximately 50.7%. The increase of $70.6 million is primarily comprised of favorable results from NRG Energy's domestic and 30

international power generation equity investments. During 2001, NRG Energy's domestic power generation investment in West Coast Power contributed $41.0 million of this increase. NRG Energy's international power generation investments in MIBRAG, Loy Yang and Kladno (ECKG) also favorably contributed to equity in earnings for 2001 in comparison to 2000. MIBRAG favorably contributed $13.3 million, Loy Yang favorably contributed $11.7 million due to improved market prices in Australia, Kladno contributed $6.6 million, Enfield contributed $7.4 million and Kondapalli contributed $3.8 million. These increases were partially offset by unfavorable results at NRG Energy's other investments accounted for under the equity method and continued reductions in the equity earnings attributable to NEO Corporation. NEO Corporation derives a significant portion of its net income from Section 29 tax credits. OPERATING COSTS AND EXPENSES For the year ended December 31, 2001, cost of majority-owned operations was $1.9 billion compared to $1.3 billion for 2000, an increase of $566.2 million or approximately 43.9%. For the years ended December 31, 2001 and 2000, cost of majority-owned operations represented approximately 66.3% and 63.9% of revenues from majority-owned operations, respectively. Cost of majority-owned operations consists primarily of cost of energy (primarily fuel costs), labor, operating and maintenance costs and non-income based taxes related to NRG Energy's majority-owned operations. Approximately 89% of the increase in operating costs and expenses for 2001 compared to 2000 of $566.2 million is primarily due to increased cost of energy incurred at NRG Energy's generating facilities. The majority of the growth in cost of majority owned operations was due to NRG Energy's recent international acquisitions. In the third and fourth quarters of 2000, NRG Energy completed the Flinders and Entrade acquisitions, during the second quarter of 2001, NRG Energy increased its ownership in the Schkopau, Cobee and Bulo Bulo projects as well as acquired the Csepel facility in Hungary. During the third quarter NRG Energy acquired a 60% interest in the Hsin Yu Energy Development Company. These recent acquisitions accounted for approximately $370.7 million of the increase in the cost of majority-owned operations the remaining increase is due primarily to increased operating costs at the South Central region generating facilities, the recently acquired Mid-Atlantic generating facilities and costs incurred by NRG Energy's power marketing operations. DEPRECIATION AND AMORTIZATION For the year ended December 31, 2001, depreciation and amortization was $212.5 million, compared to $122.9 million for the year ended December 31, 2000, an increase of $89.5 million or approximately 72.8%. 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. Approximately $57.2 million of this increase is related to increased depreciable balances resulting from recently completed domestic acquisitions and the remainder is related to recently completed international acquisitions. Through primarily acquisitions NRG Energy's net property, plant and equipment balance has grown to $9.4 billion, at the end of 2001 from $4.0 billion, at the end of 2000, an increase of $5.4 billion, or approximately 133.4%. GENERAL, ADMINISTRATIVE AND DEVELOPMENT For the year ended December 31, 2001, general, administrative and development costs were $225.7 million, compared to $172.5 million, an increase of $53.2 million or approximately 30.8%. 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. This also includes a $10.3 million expense related to Enron's bankruptcy. This amount includes a pre-tax charge of $22.4 million to establish bad debt reserves, which was partially offset by a pre-tax gain of $12.1 million on a credit swap agreement entered into as part of the NRG Energy's credit risk management program. 31

OTHER INCOME (EXPENSE) For the year ended December 31, 2001, total other expense was $416.2 million, compared to $297.4 million for the year ended December 31, 2000, an increase of $118.8 million or approximately 40.0%. The increase in total other expense of $118.8 million, from 2000, consisted primarily of an increase in interest expense that was partially offset by an increase in other income and a reduction in minority interest in earnings of consolidated subsidiaries. For the year ended December 31, 2001, interest expense (which includes both corporate and project level interest expense) was $443.7 million, compared to $293.9 million in 2000, an increase of $149.8 million or approximately 51.0%. This increase is due to increased corporate and project level debt issued during 2001. During 2001, 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 also completed its issuance of a $2 billion construction revolver during 2001 of which approximately $697.5 million is outstanding as of December 31, 2001. NRG Energy's outstanding debt balances has grown to $9.2 billion at the end of 2001 from $3.8 billion at the end of 2000. The growth in the outstanding debt balance has contributed directly to the growth in interest expense during 2001, as compared to 2000. For the year ended December 31, 2001, minority interest in earnings of consolidated subsidiaries was $6.6 million, compared to $11.3 million, a decrease of $4.7 million or approximately 42.1%, as compared to 2000. The decrease is primarily due to lower earnings from the Crockett Cogeneration project which resulted from bad debt reserves established in 2001. For the year ended December 31, 2001, other income, net, was $34.1 million, as compared to $7.9 million, for the year ended December 31, 2000, an increase of $26.2 million, or approximately 333.8%. Other income, net consists primarily of interest income on cash balances and loans to affiliates, and miscellaneous other items, including the income statement impact of certain foreign currency translation adjustments and the impact of gains and losses on the dispositions of investments. Approximately $18.0 million of the increase relates to interest on cash balances and loans to affiliates, primarily West Coast Power. The increase also includes gains on foreign currency translation adjustments and miscellaneous asset sales that were partially offset by a $3.8 million charge to write-off capitalized costs associated with the Estonia project. INCOME TAX For the year ended December 31, 2001, income tax expense was $33.4 million, compared to an income tax expense of $92.7 million for the year ended December 31, 2000, a decrease of $59.3 million, or approximately 64.0%. Approximately $14.7 million of the decrease is attributed to additional IRC Section 29 energy credits that were recorded in 2001, as compared to the same period in 2000. NRG Energy reported a worldwide effective tax rate of approximately 27.5% (before tax credits) for the year ended December 31, 2001, compared to approximately 46.0% for the year ended December 31, 2000. The overall reduction in tax rates was primarily due to the implementation of state tax planning strategies and a higher percentage of NRG's overall earnings derived from foreign projects in lower tax jurisdictions. 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 $2.2 billion, compared to $500.0 million for the year ended December 31, 1999, an increase of $1.7 billion or approximately 331.6%. NRG Energy's operating revenues from majority-owned operations were $2.0 billion compared to $432.5 million, an increase of $1.6 billion or approximately 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 32

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. OPERATING COSTS AND EXPENSES For the year ended December 31, 2000, cost of majority-owned operations, was $1.3 billion, compared to $269.9 million, an increase of $1.0 billion or approximately 377.8%. For the year ended December 31, 2000 and 1999, cost of majority-owned operations represented approximately 59.8% and 54.0% of total operating revenues and equity earnings, respectively. For the year ended December 31, 2000, the increase of $1.0 billion 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 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 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 $4.0 billion at the end of 2000 from $2.0 billion at the end of 1999, an increase of $2.0 billion or approximately 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 approximately 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 $6.0 billion at the end of 2000, compared to $3.4 billion at the end of 1999, an increase of $2.5 billion or approximately 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. 33

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 approximately 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 approximately 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 $3.8 billion at the end of 2000 from $2.0 billion 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 approximately 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 approximately 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 approximately 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. CRITICAL ACCOUNTING POLICIES AND ESTIMATES NRG Energy's discussion and analysis of its financial condition and results of operations are based upon NRG Energy's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements and related disclosures in compliance with generally accepted accounting principles (GAAP) requires the application of appropriate technical accounting rules and guidance as well as the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. The application of these policies necessarily involves judgments regarding future events, including the likelihood of success of particular projects, legal and regulatory challenges. These judgments, in and of themselves, could materially impact the financial statements and disclosures based on varying 34

assumptions, which may be appropriate to use. In addition, the financial and operating environment also may have a significant effect, not only on the operation of the business, but on the results reported through the application of accounting measures used in preparing the financial statements and related disclosures, even if the nature of the accounting policies have not changed. On an ongoing basis, NRG Energy, evaluates its estimates, utilizing historic experience, consultation with experts and other methods NRG Energy considers reasonable in particular circumstances. In any case, actual results may differ significantly from NRG Energy's estimates. Any effects on NRG Energy's business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. NRG Energy's significant accounting policies are summarized in Item 8 -- Note 2 of the Consolidated Financial Statements. The following table identifies certain of the significant accounting policies listed in Item 8 -- Note 2 of the Consolidated Financial Statements. The table also identifies the judgments required and uncertainties involved in the application of each. These policies, along with the underlying assumptions and judgments made by NRG Energy's management in their application, have a significant impact on NRG Energy's consolidated financial statements. NRG Energy identifies its most critical accounting policies as those that are the most pervasive and important to the portrayal of NRG Energy's financial position and results of operations, and that require the most difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain.

Of all of the accounting policies identified in the above table, NRG Energy believes that the following policies and the application thereof to be those having the most direct impact on NRG Energy's financial position and results of operations. CONSOLIDATION POLICY NRG Energy's consolidated financial statements include NRG Energy's accounts and those of its subsidiaries. The accounting policies for all of NRG Energy's operations are in accordance with accounting principles generally accepted in the United States. NRG Energy has investments in partnerships, joint ventures and projects, investments such as these in which NRG Energy does not have control, but has the ability to exercise significant influence over the operating and financial policies, are accounted for under the equity method. CAPITALIZATION PRACTICES, ASSET VALUATION AND PURCHASE ACCOUNTING As of December 31, 2001, NRG Energy has a carrying value of approximately $9.4 billion of net property, plant and equipment, $2.9 billion of which is under construction, representing approximately 73.1% and 22.8% of total assets, respectively. The majority of the carrying value of property, plant and equipment is the result of NRG Energy's recent asset acquisitions. These amounts represent the estimated fair values at the date of acquisition. These estimates may be adjusted based upon completion of certain procedures including third party valuations. For those assets that were or are being constructed by NRG Energy the carrying value reflects the application of NRG Energy's property, plant and equipment policies which incorporate estimates, assumptions and judgments by management relative to the capitalized costs and useful lives of NRG Energy's generating facilities. NRG Energy periodically evaluates the recoverability of the carrying value of its property, plant and equipment when events or changes in circumstances indicate that the carrying value of such assets may be impaired. Asset impairment evaluations are, by nature highly subjective. REVENUE RECOGNITION AND UNCOLLECTIBLE RECEIVABLES NRG Energy is primarily an electric generation company, operating a portfolio of majority-owned electric generating plants and certain plants in which its ownership is 50% or less which are accounted for under the equity method of accounting. NRG Energy also produces thermal energy for sale to customers and collects methane gas from landfill sites, which is then used for the generation of electricity. Both physical and financial transactions are entered into to optimize the financial performance of NRG Energy's generating facilities. Electric energy is recognized upon transmission to the customer. Capacity and ancillary revenue is recognized when contractually earned. Revenues from operations and maintenance services, is recognized when the services are performed. NRG Energy uses the equity method of accounting to recognize it's pro rata share of the net income or loss of its unconsolidated investments. NRG Energy continually assesses the collectibility of its receivables and in the event it believes a receivable to be uncollectible an allowance for doubtful accounts is recorded or in the event of a contractual dispute the receivable and corresponding revenue may be considered unlikely of recovery and not recorded in the financial statements until management is satisfied that it will be collected. DERIVATIVE FINANCIAL INSTRUMENTS In January 2001, NRG Energy adopted SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as 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 the fair value of non-hedge derivatives 36

are immediately recognized in earnings. Changes in the fair value of derivatives accounted for as hedges are either recognized in earnings as offset to the charges in the fair value of the related hedged assets, liabilities and firm commitments or for forecasted transactions, deferred and recorded as a component of accumulated other comprehensive income (OCI) until the hedged transactions occur and are recognized in earnings. NRG Energy primarily applies SFAS No. 133 to long-term power sales contracts, long-term gas purchase contracts and other energy related commodities financial instruments used to mitigate variability in earnings due to fluctuations in spot market prices, hedge fuel requirements at generation facilities and protect investments in fuel inventories. SFAS No. 133 also applies to interest rate swaps and foreign currency exchange rate contracts. The application of SFAS No. 133 results in increased volatility in earnings due to the impact market prices have on the market positions and financial instruments that NRG Energy has entered into. In determining the fair value of these derivative/financial instruments NRG Energy uses estimates, various assumptions, judgement of management and when considered appropriate third party experts in determining the fair value of these derivatives. LIQUIDITY AND CAPITAL RESOURCES Historically, NRG Energy and its subsidiaries have obtained cash from operations, issuance of debt and equity securities, borrowings under credit facilities, capital contributions from Xcel Energy, reimbursement by Xcel Energy 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. NRG Energy targets a financial strategy that sustains investment grade ratings and diversifies investment risk. Specifically, NRG Energy seeks to fund an average of 50% of its project investments with non-recourse project level debt, 20% with senior unsecured recourse debt, and 30% with equity and internal cash generation. The proportion of project financing varies depending on the dispatch and the quantity of revenues under contract so that base load or highly contracted plants will typically support greater than 50% non-recourse debt; whereas merchant or peaking assets will support less than 50% financing. When taken in total NRG Energy has and will continue to arrange 50% of its financing with non-recourse project level debt. Substantially all of NRG Energy's operations are conducted by project subsidiaries and project affiliates. NRG Energy's cash flow and ability to service corporate-level indebtedness when due is dependent upon receipt of cash dividends and distributions or other transfers from NRG Energy's projects and other subsidiaries. The debt agreements of NRG Energy's subsidiaries and project affiliates generally restrict their ability to pay dividends, make distributions or otherwise transfer funds to NRG Energy. As of December 31, 2001, six of NRG Energy's subsidiaries and project affiliates are restricted from making cash payments to NRG Energy. Loy Yang, Killingholme, Energy Center Kladno and Louisiana Generating do not currently meet the minimum debt service coverage ratios required for these projects to make payments to NRG Energy; Batesville is resolving equipment problems that will cause its debt service coverage ratio to fall below the minimum required for distribution, though, irrespective of the debt service coverage ratio, no distributions to NRG Energy were anticipated from Batesville in 2002; and Crockett Cogeneration is limited in its ability to make distributions to NRG Energy and the other partners. NRG Energy believes that the situations at Louisiana Generating, Energy Center Kladno, Batesville and Killingholme do not create an event of default and will not allow the lenders to accelerate the project financings. The forced outage of one 500 MW unit at Loy Yang combined with current market prices may lead to an event of default and the possible acceleration of the Loy Yang project debt in the fourth quarter of 2002, but if insurance claims are paid and budgeted revenues and costs are achieved, along with replacement of the damaged unit as scheduled, default will be avoided. Loy Yang then has an AUD $500 million repayment due in May 2003 that will need to be refinanced prior to maturity. The bankruptcy of PG&E creates the potential for a covenant default that would result in the acceleration of the debt at Crockett if not resolved with the lenders. Management has engaged in active discussions with the lenders to Crockett since PG&E filed for bankruptcy in April 2001, and Crockett is being paid each month 37

by PG&E since the bankruptcy filing. Thus NRG Energy believes that an acceleration of the Crockett debt is unlikely. The U.S. Federal Bankruptcy Court recently approved the power purchase agreement thereby increasing the likelihood that Crockett soon will be permitted by the lenders to distribute any excess cash flows to the partners. In all of these cases NRG Energy's corporate-level financial obligations to project lenders is limited to no more than six-months debt service. CASH FLOWS

2001 2000 1999 ---- ---- ---- Net cash provided by (used in) operating activities (in thousands)............................................... $276,014 $361,678 ($11,380)
Net cash provided by operating activities decreased during 2001 compared with 2000, primarily due to adverse changes to working capital and increased undistributed equity earnings from unconsolidated affiliates. These decreases to net cash were partially offset by increases in net income after non-cash adjustments for depreciation and amortization in 2001 as compared to 2000. The adverse changes to working capital are primarily due to increases in inventory balances, accrued income taxes receivables and changes in other long term assets and liabilities, partially offset by a favorable change in other current liabilities. 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.
2001 2000 1999 ---- ---- ---- Net cash used in investing activities (in thousands)........................................ ($4,335,641) ($2,204,148) ($1,668,613)
Net cash used in investing activities increased in 2001, compared with 2000, primarily due to additional acquisitions of electric generating facilities and increased capital expenditures and project investments. Net cash used in investing activities increased in 2000, compared with 1999, primarily due to acquisitions of electric generating facilities and increased capital expenditures and project investments.
2001 2000 1999 ---- ---- ---- Net cash provided by financing activities (in thousands)........................................... $4,153,546 $1,905,870 $1,705,095
Net cash provided by financing activities during 2001 increased, compared to 2000 due to the issuance of debt and equity securities to finance asset acquisitions. 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. PROSPECTIVE CAPITAL REQUIREMENTS In 2002, NRG Energy expects to complete the acquisition from FirstEnergy, for approximately $1.6 billion in cash and assumed debt, of a portfolio of assets. The FirstEnergy acquisition is expected to be financed with an $875 million lease with limited recourse to NRG Energy, the assumption of $145 million of municipal debt secured by the Bay Shore facility, and $575 million of capital raised directly by NRG Energy through internal cash flow and the sale of existing assets. CONSTRUCTION PROGRAM REQUIREMENTS As of December 31, 2001, NRG Energy estimates its capital expenditure program to be approximately $7.5 billion for the period 2002 - 2006. NRG Energy expects to spend approximately $1.9 billion in 2002, $1.8 billion in 2003 and $1.6 billion in 2004. These estimated expenditures are primarily for NRG Energy's project development program. For 2002, NRG Energy's capital requirements reflect the expected construction costs for those projects currently under construction and those expected to begin construction in the near future. In January 2002, NRG Energy announced that it planned to scale back its previously announced acquisition and construction plans in order to enhance its financial position and improve liquidity in 2002. The 38

above amounts reflect this previously announced scaled back construction schedule. In March 2002, Xcel Energy commenced an exchange offer by which Xcel Energy would acquire all of the outstanding publicly held shares of NRG Energy. If successful, Xcel Energy has stated that it intends to delay or cancel $1.6 billion of planned projects, among other actions. The proposed delays or cancellations have not been factored into the above expected capital expenditures. 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. ACQUISITION AND CONSTRUCTION PROGRAM CAPITAL SOURCES 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 year ended December 31, 2001, NRG Energy financed its acquisition program and construction activities through a combination of the following corporate level and project level financings and operating cash flows. The specifics of such financing arrangements are detailed below: As of December 31, 2001, NRG Energy had a $500 million recourse revolving credit facility under a commitment fee arrangement that matures in March of 2002. This facility provided short-term financing in the form of bank loans. At December 31, 2001, NRG Energy had $170 million outstanding under this facility. In March 2002, the revolving credit facility terminated and was replaced with a $1.0 billion 364-day corporate level unsecured revolving line of credit with ABN AMRO Bank, N.V. as Administrative Agent. NRG Energy's $1.0 billion 364-day revolving line of credit terminates on March 7, 2003. The facility is unsecured and provides for borrowings of "Base Rate Loans" and "Eurocurrency Loans". The Base Rate Loans bear interest at the greater of the Administrative Agent's prime rate or the sum of the prevailing per annum rates for overnight funds plus 0.5% per annum, plus an additional margin which varies based upon NRG Energy's utilization of the facility and its then-current senior debt credit rating. The Eurocurrency loans bear interest at an adjusted rate based on LIBOR plus an adjustment percentage which varies depending on NRG Energy's senior debt credit rating and the amount outstanding under the facility. The facility contains covenants that, among other things, restrict the incurrence of liens and require NRG Energy to maintain a net worth of at least $500 million plus 25% of NRG Energy's consolidated net income from January 1, 2002 through the determination date. In addition, NRG Energy must maintain a debt to capitalization ratio of not more than 0.68 to 1.00, and must maintain an interest coverage ratio of not less than 2.00 to 1.00, as determined at the end of each fiscal quarter. The failure to comply with any of these covenants would be an Event of Default under the terms of the credit agreement. In May 2001, NRG Energy's wholly-owned subsidiary, NRG Finance Company I LLC, entered into a $2 billion revolving credit facility. The facility has been and will be used to finance the acquisition, development and construction of power generating plants located in the United States and to finance the acquisition of turbines for such facilities. The facility provides for borrowings of base rate loans and Eurocurrency loans and is secured by mortgages and security agreements in respect of the assets of the projects financed under the facility, pledges of the equity interests in the subsidiaries or affiliates of the borrower that own such projects, and by guaranties from each such subsidiary or affiliate. Provided that certain conditions are met that assure the lenders that sufficient security remains for the remaining outstanding loans, the borrower may repay loans relating to one project and have the liens relating to that project released. Loans that have been repaid may be re-borrowed, as permitted by the terms of the facility. The facility terminates on May 8, 2006. The facility is non-recourse to NRG Energy other than its obligation to contribute equity at certain times in respect of projects and turbines financed under the facility. As of December 31, 2001, the aggregate amount outstanding under this facility was $697.5 million. 39

In January 2001, NRG Energy entered into a bridge credit agreement, with a final maturity date of December 31, 2001. Approximately $600 million was borrowed under this facility to partially finance NRG Energy's acquisition of the LS Power generation assets. During March of 2001, NRG Energy raised net proceeds of approximately $473.4 million through a second common stock offering of 18.4 million shares of common stock. In addition, approximately $278.4 million of net proceeds were 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 were used for general corporate purposes. In April 2001, NRG Energy issued $690 million of senior notes in two tranches. The first tranche of $350 million matures in April 2011 and bears an interest rate of 7.75%. The second tranche of $340 million matures in April 2031 and bears an interest rate of 8.625%. The net proceeds of the issuance were used for repayment of short-term indebtedness incurred to fund acquisitions, for investments, general corporate purposes and to provide capital for future planned acquisitions. In June 2001, NRG Energy entered into a $600 million term loan facility. The facility was unsecured and provided for borrowings of base rate loans and Eurocurrency loans. The facility had a termination date of June 21, 2002. As of December 31, 2001, the aggregate amount outstanding under this facility was $600 million. NRG Energy repaid this facility in March 2002 in conjunction with the closing of its new $1.0 billion unsecured corporate level revolving line of credit and the receipt of $300 million of cash from Xcel Energy. On June 22, 2001, NRG Mid Atlantic Generating LLC (Mid Atlantic), a wholly owned subsidiary of NRG Energy, borrowed approximately $420.9 million under a five year term loan agreement (Agreement) to finance, in part, the acquisition of certain generating facilities from Conectiv. The Agreement terminates in November 2005 and provides for a total credit facility of $580 million. In June 2001, NRG Energy through its wholly owned subsidiaries, Brazos Valley Energy LP and Brazos Valley Technology LP, entered into a $180 million non-recourse construction credit facility to fund the construction of the 600 MW Brazos Valley gas-fired combined cycle merchant generation facility located in Fort Bend County, Texas. As of December 31, 2001, there exists an outstanding balance of $159.8 million under this credit agreement. In connection with NRG Energy's acquisition of the Audrain facilities, NRG Energy has recognized a capital lease on its balance sheet in the amount of $239.9 million, as of December 31, 2001. The capital lease obligation is recorded at the net present value of the minimum lease obligation payable. The lease terminates in May 2023. In addition, approximately $326 million was drawn down on NRG Energy's construction revolver to refinance NRG Energy's investment in the Audrain County Municipal bonds originally issued to finance the construction of the Audrain generating facility. In July 2001, NRG Energy completed the sale of $500 million of unsecured senior notes. The senior notes were issued in two tranches, the first tranche of $340 million of 6.75% Senior Notes is due July 2006 and the second tranche of $160 million of 8.625% Senior Notes is due April 2031. NRG Energy received net proceeds from the sale of both series of notes of approximately $505.2 million, including interest on the senior notes due 2031, accrued from April 5, 2001. The net proceeds were used to repay all amounts outstanding under NRG Energy's revolving credit agreement and for investments, other general corporate purposes and to provide capital for planned acquisitions. In August 2001, NRG Energy entered into a 364-day term loan of up to $296 million. The credit facility was structured as a senior unsecured loan and was partially non-recourse to NRG Energy. The proceeds were used to finance the McClain generating facility acquisition. In November 2001 the credit facility was repaid from the proceeds of a $181.0 million term loan and $8.0 million working capital facility entered into by NRG McClain LLC, with Westdeutsche Landesbank Girozentrale, New York branch, as agent (Non-recourse to 40

NRG Energy). The final maturity date of the facility is November 30, 2006. As of December 31, 2001, the aggregate amount outstanding under this facility was $159.9 million. REGISTRATION STATEMENTS In December 2000, NRG Energy filed a universal shelf registration statement with the SEC. Based on this registration, NRG Energy could issue up to $1.65 billion of debt securities, preferred stock, common stock, depositary shares, warrants and convertible securities. This registration statement included $150 million of securities that were 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. There are no remaining amounts available under this shelf registration as of December 31, 2001. In June 2001, NRG Energy filed a shelf registration with the SEC to sell up to $2 billion in debt securities, common and preferred stock, warrants and other securities. NRG Energy expects to use the net proceeds for general corporate purposes, which may include the financing and development of new facilities, working capital and debt reduction. In July 2001, NRG Energy completed the sale of $500 million of unsecured senior notes under this shelf registration, approximately $1.5 billion remains available under this facility at December 31, 2001. PREVIOUSLY EXISTING DEBT AND DEBT ASSUMED UPON ACQUISITION For additional information on NRG Energy's short term and long term borrowing arrangements, see Item 8 -- Note 9 to the Consolidated Financial Statements. PROJECTED FINANCING NEEDS 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. As outlined above, NRG Energy is expected to need approximately $7.5 billion during the period 2002 - 2006 in order to meet its planned construction schedule. NRG Energy plans to issue equity in the total amount of $1.1 billion during the period 2002 - 2006, and project level long term debt financing in the amount of $6.3 billion during this same period of time. If Xcel Energy successfully completes its tender offer, NRG Energy's equity capital requirements would come from cash infusions from Xcel Energy. NRG Energy believes it will be able to raise the necessary funding in the capital markets in the near term because most of the project level construction financing has already been committed either through the $2.0 billion construction revolver or project specific construction financings. IMPACT OF A DOWNGRADE OF CREDIT RATING NRG Energy's unsecured credit rating is BBB- from Standard & Poors's and Baa3 from Moody's Investors Service. In December 2001, Moody's placed NRG Energy's credit rating on review for potential downgrade. NRG Energy's credit rating remains under review by Moody's for potential downgrade. As of December 31, 2001, NRG Energy's off-balance sheet obligations pursuant to its guarantees of performance, equity and indebtedness obligations of its subsidiaries totaled approximately $721.7 million. NRG Energy is directly liable for the obligations of certain of its project affiliates and other subsidiaries pursuant to guarantees relating to certain of their indebtedness, equity and operating obligations. In addition, in connection with the purchase and sale of fuel emission credits and power generation products to and from third parties with respect to the operation of some of NRG Energy's generation facilities in the United States, NRG Energy may be required to guarantee a portion of the obligations of certain of its subsidiaries. If Moody's or Standard & Poor's were to downgrade NRG Energy, many of the corporate guarantees and commitments currently in place would need to be supported with letters of credit or cash collateral within 5 to 30 days. As of December 31, 2001, the amount of collateral required, if NRG Energy were downgraded, was approximately $960 million, to satisfy certain of the above mentioned guarantees and obligations associated with the $2 billion construction/acquisition revolver. Of the $960 million in collateral that could be required, 41

approximately $200 million relates to NRG Energy's guarantees of debt service reserve accounts required by some of its project-level financings; approximately $400 million relates to NRG Energy's power marketing activities; and $360 million would be required to support its Contingent Equity Guarantee associated with the $2 billion construction/acquisition revolver. Because NRG Energy limits the amount of the guarantees it issues to support NRG Power Marketing's activities, and because of the relatively small number of margin accounts in place, even very large changes in market conditions would not have a material impact on the $400 million of collateral that would be required for NRG Power Marketing in the event of a downgrade. In the event of a downgrade, NRG Energy would expect to meet its collateral obligations with cash on hand, available credit lines provided under its revolving line of credit potentially from, liquidity support from Xcel Energy and the issuance of debt into capital markets. Xcel Energy has stated its plan to infuse approximately $600 million of equity into NRG Energy in 2002 in connection with its exchange offer and merger. Of this amount, $300 million has already been provided in the form of a convertible subordinated note that Xcel Energy has said it will cancel if its exchange offer and merger are completed. If the offer and merger are not completed, Xcel Energy has said it will continue to evaluate the terms and timing of any additional investment in NRG Energy. In March 2002, NRG Energy successfully replaced its corporate level $500 million unsecured revolving line of credit facility with a new 364-day $1.0 billion corporate level unsecured revolving line of credit. In addition, NRG Energy will maintain its $125 million letter of credit facility and plans to secure an additional $125 million credit facility for total credit facilities of $1.25 billion to be available in 2002. The Contingent Equity Guarantee associated with NRG Energy's construction/acquisition revolver could increase to a maximum of $850 million by the end of 2002 as NRG Energy utilizes the capacity of the construction/acquisition revolver. Therefore, the amount of collateral required by the end of 2002 could increase to $1.45 billion. ASSET SALES In January 2002, NRG Energy also announced that it has reviewed its portfolio of operating assets and has identified approximately 650 MW of less strategic facilities that it plans to put up for sale in the near term and expects to raise an additional $350-$400 million cash after paying off any project level debt. OFF BALANCE-SHEET ITEMS As of December 31, 2001, NRG Energy does not have any significant relationships with structured finance or special purpose entities that provide liquidity, financing or incremental market risk or credit risk. However, as noted in Item 8 -- Note 9 to the Consolidated Financial Statements, NRG Energy issued $250 million of 8.70% ROARS due March 2020 through an unconsolidated guarantor trust. The sole assets of the trust consist of L160 million of Reset senior notes due March 2020. NRG Energy has numerous investments of generally less then 50% interests in numerous energy and energy related entities that are accounted for under the equity method of accounting as disclosed in Item 8 -- Note 6 to the Consolidated Financial Statements. NRG Energy's pro-rata share of non-recourse debt held by unconsolidated affiliates was approximately $940 million as of December 31, 2001. In the normal course of business NRG Energy may be asked to loan funds to these entities on both a long and short-term basis. Such transactions are generally accounted for as accounts payables and receivables to/from affiliates and notes receivables from affiliates and if appropriate, bear market based interest rates. For additional information regarding amounts accounted for as notes receivables to affiliates see Item 8 -- Note 8 to the Consolidated Financial Statements. CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS NRG Energy has a variety of contractual obligations and other commercial commitments that represent prospective cash requirements in addition to its capital expenditure programs. The following is a summarized 42

table of contractual obligations. See additional discussion in Item 8 -- Notes 9 and 17 to the Consolidated Financial Statements.

INTERDEPENDENT RELATIONSHIPS NRG Energy does not have any significant interdependent relationships. Since it is a majority owned subsidiary of Xcel Energy there are certain related party transactions that take place in the normal course of business. For additional information regarding NRG Energy's related party transactions see Item 8 -- Note 7 to the Consolidated Financial Statements and Item 13 -- Certain Relationships and Related Transactions. DOMESTIC ENVIRONMENTAL MATTERS The construction and operation of power projects are subject to stringent environmental protection and land use regulation in the United States. These laws and regulations generally require lengthy and complex processes to obtain licenses, permits and approvals from federal, state and local agencies. If such laws and regulations are tightened and NRG Energy's facilities are not exempted from coverage, extensive modifications to further reduce environmental impacts could be required. NRG Energy and its subsidiaries continue to strive to exceed 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 Item 8 -- Note 17 to the Consolidated Financial Statements. FEDERAL INITIATIVES Numerous Federal and legislative initiatives are being undertaken to control pollutant emissions from fossil-fuel-fired combustion units. All of NRG Energy's power plants will be affected in some manner by 43

changes that are expected to occur. In Congress, legislation is being proposed that would impose annual caps on U.S. power plant emissions of nitrogen oxide (NO(X)), sulfur dioxide (SO(2)), mercury, and, in some instances, carbon dioxide (CO(2)). NRG Energy is currently participating in the debates around such legislative proposals as a member of the Electric Power Supply Association. The U.S. Environmental Protection Agency (USEPA) is set to propose in December 2003 rules governing mercury emissions from power plants; these rules are set to be finalized on December 2004. In support of maintaining this schedule, a thorough review of existing power plant mercury emissions data is underway by USEPA and critical stakeholders. Federal rules governing ozone season NO(X) emissions across the eastern United States have been finalized and will now occur in two phases. The first phase of restrictions will occur in the Ozone Transport Commission region during the 2003 and subsequent ozone seasons; all of NRG Energy's existing, wholly owned generating units in the Northeast and Mid-Atlantic regions are included in this part of the program. The second phase of NO(X) reductions will extend to states within the ozone transport assessment region and restrict 2004 and subsequent ozone season NO(X) emissions in most states east of the Mississippi River. New rules governing cooling water intake structures at existing facilities are to be proposed during the first quarter of 2002 and finalized in August of 2003. These rules will specify rules governing the location, design, construction, and capacity of cooling water intake structures and reflect the best technology available for minimizing adverse environmental impact therewith. Other Federal initiatives that would govern regional haze and fine particulate matter are underway, but under extended compliance timeframes. REGIONAL INITIATIVES WEST COAST REGION The California Air Resources Board (CARB) is required under Senate Bill 28 (SB 28) to develop a schedule for retrofitting, by December 31, 2004, emission controls on existing power generation facilities. SB 28 requires that the emission control retrofit schedule be completed by CARB on or before July 1, 2002. CARB's current schedule for implementing the requirements of SB 28 show final rulemaking by spring of 2003. Because the SB 28 emission control retrofit requirements are not intended to change local or regional air quality control requirements, it is difficult to predict what, if any, additional emission controls would be required on NRG Energy's California assets. The El Segundo and Long Beach Generating Stations are both regulated by the South Coast Air Quality Management District's (SCAQMD) Regional Clean Air Incentives Market (RECLAIM) program. This program, which regulates NO(X) emissions in the Los Angeles area, was amended on May 11, 2001 and included major changes with respect to power generation facilities. New RECLAIM Rule 2009 requires all existing power generation facilities to meet Best Available Retrofit Control Technology (BARCT) for NO(X) emissions from all utility boilers by January 1, 2003, and for all gas turbine units by January 1, 2004. Under the new rule, existing power generation facilities were required to submit compliance plans by September 1, 2001, listing how each unit at the stations would meet BARCT by the deadlines. El Segundo's compliance plan did not plan for any additional NO(X) controls to meet BARCT since Units 3 & 4 are already equipped with SCR technology (first installed on Unit 4 in 1995 and on Unit 3 in 2001) and Units 1 & 2 are expected to be decommissioned in order to build a new 621 MW combined cycle plant. The SCAQMD denied the El Segundo Compliance Plan in late 2001, citing that the SCRs on Units 3 & 4 could be cost effectively modified to meet a lower NO(X) emission rate. El Segundo Power, LLC has appealed this denial because the SCAQMD criteria for cost effectiveness assumes the units operate at 100% capacity factor, which is not how they truly operate and is contradictory to SCAQMD rules. The appeal case is still pending. The Long Beach Generating Station's compliance plan demonstrated that SCR technology is neither technically feasible nor cost effective and called for approximately $1 million in modifications to the existing steam injection system to meet BARCT. This compliance plan is still pending a decision by SCAQMD. 44

NORTHEAST REGION Final rules implementing changes in air regulations in the states of Massachusetts and Connecticut were promulgated in 2000. The Connecticut rules required that existing facilities reduce their emissions of SO(2) in two steps, the first of which took place on January 1, 2002. The second milestone change is set to occur on January 1, 2003. NRG Energy is operating in full compliance with the first phase now and expects to comply with step phase changes in accordance with the established schedule. Connecticut's rules governing emissions of NO(X) were modified to restrict the average, non-ozone season NO(X) emission rate to 0.15 pound per million Btu heat input. NRG Energy will comply with the new NO(X) rules, in part, through selective firing of natural gas. The new Massachusetts rules set forth schedules under which six existing coal-fired power plants were required to meet stringent emission limits for NO(X), SO(2), mercury, and CO(2). Control of carbon monoxide and particulate matter emissions were reserved for future consideration. NRG Energy has submitted an Emission Control Plan (ECP) to the Massachusetts Department of Environmental Protection (MADEP) which identified natural gas reburn technology as an option for meeting the NO(X) and SO(2) limits specified in the new rule. NRG Energy is conducting ongoing discussions with MADEP with respect to finalizing its ECP. By December 1, 2002, MADEP is to complete an evaluation of the technological and economic feasibility of controlling and eliminating emissions of mercury from the combustion of solid fossil fuel in Massachusetts. Within six months of completing the feasibility evaluation, MADEP must propose emission standards for mercury, with a proposed compliance date of October 1, 2006. NRG Energy is still considering its options with respect to how it will address MADEP's CO(2) emission standards. Such options include filing a legal challenge with respect to MADEP's legal authority to regulate CO(2) emissions. New rules reducing allowable SO(2) and NO(X) emissions from large, fossil-fuel-fired combustion units in New York State were expected to be proposed in January 2002. No word has been released with regard to the reason the proposal of these rules has been delayed. NRG Energy has provided comments as part of New York State coalition of electricity producers on major conceptual flaws contained in pre-publication releases of the proposed rule. SOUTH-CENTRAL REGION The Louisiana Department of Environmental Quality has promulgated State Implementation Plan revisions to bring the Baton Rouge ozone non-attainment area into compliance with National Ambient Air Quality Standards. NRG Energy participated in development of the revisions which require NO(X) emissions to be reduced at the Big Cajun II Power Station to 0.21 pounds per million Btu heat input. This revision of the Louisiana air rules would appear to constitute a change-in-law covered by agreement between Louisiana Generating LLC and the electric cooperatives allowing the costs of added controls to be passed through to the cooperatives. MID-ATLANTIC AND NORTH-CENTRAL REGION No material impending rule changes affecting NRG Energy's existing facilities have been proposed in either of these regions. INTERNATIONAL ENVIRONMENTAL MATTERS 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. 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 45

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. RECENT ACCOUNTING DEVELOPMENTS In June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets". SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized but instead be tested for impairment in accordance with SFAS No. 121, "Accounting for the Impairment of Long-lived assets and for Long-lived Assets to Be Disposed Of." Goodwill will no longer be amortized to comply with the provisions of SFAS No. 142. Instead, goodwill and intangible assets that will not be amortized should be tested for impairment annually and on an interim basis if an event occurs or a circumstance changes between annual tests that may reduce the fair value of a reporting unit below its carrying value. An impairment test is required to be performed within six months of the date of adoption, and the first annual impairment test must be performed in the year the statement is initially adopted. NRG Energy and its subsidiaries, as required, adopted SFAS No. 142 on January 1, 2002. At December 31, 2001, NRG Energy had intangible assets of $97.1 million, including $56.6 million of goodwill. These amounts and all intangible assets and goodwill acquired in the future will be accounted for under the new accounting standard. The new accounting standard is expected to initially increase earnings by an immaterial amount due to the elimination of regular amortization expense, but occasionally cause reductions in earnings when impairment write-downs of goodwill and/or intangible assets are required. Expense recognized for amortization of goodwill in 2001 was $3.8 million. NRG Energy does not expect to recognize any asset impairments as a result of adopting SFAS No. 142 in the first quarter of 2002. In June 2001, FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." This statement addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. SFAS No. 143 requires an entity to recognize the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Upon initial recognition of a liability for an asset retirement obligation, an entity shall capitalize an asset retirement cost by increasing the carrying amount of the related long-lived asset by the same amount as the liability. SFAS No. 143 is effective for financial statements issued for fiscal years beginning after June 15, 2002. NRG Energy has not completed its analysis of SFAS No. 143. In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This statement addresses financial accounting and reporting for the impairment or disposal of long-lived assets. SFAS No. 144 retains and expands upon the fundamental provisions of existing guidance related to the recognition and measurement of the impairment of long-lived assets to be held and used and the measurement of long-lived assets to be disposed of by sale. Generally, the provisions of SFAS No. 144 are effective for financial statements issued for fiscal years beginning after December 15, 2001. CALIFORNIA LIQUIDITY CRISIS NRG Energy's California generation assets include a 57.67% interest in Crockett Cogeneration, a 39.5% interest in the Mt. Poso facility and a 50% interest in the West Coast Power partnership with Dynegy. In March 2001, the California PX filed for bankruptcy under Chapter 11 of the Bankruptcy Code, and in April 2001, Pacific Gas & Electric Company (PG&E) also filed for bankruptcy under Chapter 11. PG&E's filing delayed collection of receivables owed to the Crockett facility. In September 2001, PG&E filed a proposed plan of reorganization. Under the terms of the proposed plan, which is subject to challenge by interested parties, unsecured creditors such as NRG Energy's California affiliates would receive 60% of the amounts owed upon approval of the plan. The remaining 40% would be paid in negotiable debt with terms from 10 to 30 years. The California Power Exchange's (PX) ability to repay its debt is dependent on the extent to which it receives payments from PG&E and SCE. On December 21, 2001, the California bankruptcy court affirmed the Mt. Poso and Crockett Power Purchase Agreement (it had previously affirmed Mt. Poso's agreement) with PG&E and, in respect of the Crockett Power Purchase Agreement, approved a twelve-month 46

repayment schedule of all past due amounts totaling $49.6 million, plus interest. The first payment of $6.2 million, including accrued interest, was received on December 31, 2001. NRG Energy's share of the net amounts owed to West Coast Power by the California ISO and PX totaled approximately $85.1 million as of December 31, 2001, compared to $101.8 million at December 31, 2000. These amounts reflect NRG Energy's share of (a) total amounts owed to West Coast Power less (b) amounts that are currently treated as disputed revenues and are not recorded as accounts receivable in the financial statements of West Coast Power LLC, and reserves taken against accounts receivable that have been recorded in the financial statements. The decrease is primarily attributed to cash collections from the California ISO during the fourth quarter of 2001. ENRON EXPOSURE During the fourth quarter of 2001, NRG Energy recorded a net after-tax expense of approximately $6.7 million related to Enron Corp.'s bankruptcy. This amount includes a $14.2 million after-tax charge to establish bad debt reserves, which was partially offset by a $7.5 million after-tax gain on a credit swap agreement entered into as part of NRG Energy's credit risk management program. NRG Energy has fully provided for its exposure to Enron; however, as with any receivable, NRG Energy will pursue collection of all amounts outstanding through the ordinary course of business. In addition, an Enron subsidiary, NEPCO, is serving as the construction contractor for two greenfield development projects, the Kendall and Nelson projects (2,336 MW combined) currently under construction in Illinois. Enron guaranteed NEPCO's obligations under the construction contracts. To date, the actual construction and engineering work on both projects has continued without disruption and NRG Energy expects the projects to achieve commercial operations on schedule. NRG Energy believes its overall construction costs for these two projects will increase by approximately $22 per kilowatt, as a result of the need to restructure the underlying construction contracts following the Enron bankruptcy.

ITEM 7A -- 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, 2001, if the value of the Czech koruna decreases by 10% in relation to the U.S. dollar and the German deutsche mark, NRG Energy would record a $4.2 million loss (after tax) on the currency transaction adjustment. If the value of the Czech koruna increased by 10%, NRG Energy would record a $4.2 million gain (after tax) on the currency transaction adjustment. Additionally, NRG Energy has in investment in Hsin Yu in Taiwan which holds a payable denominated in U.S. Dollars. If the New Taiwan Dollar increased by 10%, NRG Energy would record a $0.8 million gain (after tax) on the currency adjustment. These currency fluctuations are inherent to the debt structure of the projects and not indicative of the long-term earnings potential of the investments. NRG Energy is also subject to currency risks associated with foreign denominated distributions from international investments. In the normal course of business NRG Energy receives distributions denominated in Australian Dollar, British Pound, Euro, Hungarian Forint and Czech Koruna. Upon completion of the Itiquira plant in Brazil, NRG Energy will also be subject to currency risk with the Brazilian Real. NRG Energy engages in a Board approved strategy of hedging foreign denominated cash flows through a program of matching currency inflows and outflows, and to the extent required, fixing the U.S. Dollar equivalent of net foreign denominated distributions with currency forward and swap agreements with highly credit worthy financial institutions. As of December 31, 2001, NRG Energy had two foreign currency exchange contracts with notional amounts of $46.3 million. If the contracts had been discontinued on December 31, 2001, NRG Energy would have owed the counter-parties approximately $2.4 million. INTEREST RATE RISK In order to minimize NRG Energy's exposure to changes in interest rates, NRG Energy attempts to maintain 60-70% of its debt as fixed rate, which has proven historically to provide the lowest volatility and price, when calculated on an annual basis. When necessary, NRG Energy will employ the use of interest rate swaps with highly credit worthy counter-parties to maintain this mix of fixed and floating rates. As of December 31, 2001, NRG energy had various interest rate swap agreements with notional amounts totaling approximately $2.4 billion. If the swaps had been discontinued on December 31, 2001, NRG Energy would have owed the counter parties approximately $81.5 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 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, 2001, a 100 basis point change in the benchmark rate on NRG Energy's variable rate debt would impact net income by approximately $16.6 million. As of December 31, 2000, NRG Energy did 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 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 49

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. NRG Energy utilizes a "Value-at-Risk" (VAR) model to estimate a maximum potential loss in the fair value of its commodity portfolio including generation assets, load obligations and bilateral physical and financial transactions. The key assumptions for the NRG Energy VaR model include (1) a lognormal distribution of price returns (2) three day holding period and (3) a 95% confidence interval. The volatility estimate is based on the implied volatility for at the money call options. This model encompasses the following generating regions: Entergy, NEPOOL, NYPP, PJM, WSCC, SPP and Main. The estimated maximum potential three-day loss in fair value of its commodity portfolio, calculated using the VAR model is as follows:

(IN MILLIONS) ------------- Year end December 31, 2001.................................. $ 71.7 Average..................................................... 78.8 High........................................................ 126.6 Low......................................................... 58.6 Year end December 31, 2000.................................. $116.0 Average..................................................... 80.0 High........................................................ 125.0 Low......................................................... 50.0
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 actively manages its counter-party credit risk. NRG Energy has an established credit policy in place to minimize overall credit risk. Important elements of this policy include ongoing financial reviews of all counter-parties, established credit limits, as well as monitoring, managing, and mitigating credit exposure.

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, together with its majority owned subsidiaries and affiliates, 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. 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 Energy). The shares of NRG Energy's class A common stock previously held by NSP are now owned by Xcel Energy. As of December 31, 2001, Xcel Energy owned a 74% interest in NRG Energy's outstanding common and class A common stock, representing 97% of the total voting power of NRG Energy's common stock and class A common stock. In February 2002, Xcel Energy announced its intention to commence an exchange offer to acquire all of NRG Energy's outstanding common stock, and stated its intention to close this transaction in April 2002 (See Note 23). 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. Investments in such businesses in which NRG Energy does not have control, but has the ability to exercise significant influence over the operating and financial policies, are accounted for under the equity method. 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 weighted average cost or market and consists principally of fuel oil, spare parts, coal, kerosene, emission allowance credits and raw materials used to generate steam. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at original cost or the present value of minimum lease payments for assets under capital leases. Significant additions or improvements extending asset lives are capitalized, 57

while repairs and maintenance are charged to expense as incurred. Depreciation is computed using the straight-line method over the following estimated useful lives:

Facilities and improvements................................. 10-45 years Machinery and equipment..................................... 7-30 years Office furnishings and equipment............................ 3-5 years
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 accordance with Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of." IMPAIRMENT OF LONG LIVED ASSETS 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 asset under construction is ready for its intended use. Capitalized interest was approximately $27,175,000, $2,667,000, and $287,000 in 2001, 2000 and 1999, respectively. 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 a project begins operation, previously capitalized project costs are reclassified to equity investments in affiliates or property plant and equipment 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 Debt issuance costs are capitalized and amortized over the terms of the related debt. INTANGIBLE ASSETS Goodwill results when NRG Energy purchases a business at a price higher than the underlying fair value of the net assets. Effective January 1, 2002, NRG Energy implemented SFAS No. 142, "Goodwill and Other Intangible Assets." (SFAS No. 142). At December 31, 2001, NRG Energy had intangible assets of $97.1 million including $56.6 million of goodwill. These amounts and all intangible assets and goodwill acquired in the future will be accounted for under the new accounting standard. The new accounting can be expected to initially increase earnings due to the elimination of regular amortization expense, but periodically cause reductions in earnings when impairment write-downs of goodwill and/or intangible assets are required. 58

INCOME TAXES In March 2001, NRG Energy was deconsolidated from Xcel Energy for Federal income tax purposes. Prior to March 13, 2001, NRG Energy was included in the consolidated tax returns of Xcel Energy. NRG Energy calculated its income tax provision on a separate return basis under a tax sharing agreement with Xcel Energy as discussed in Note 10. Current Federal and certain state income taxes were payable to or receivable from Xcel Energy. Deferred income taxes are recognized for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. REVENUE RECOGNITION NRG Energy is primarily an electric generation company, operating a portfolio of majority-owned electric generating plants and certain plants in which its ownership interest is 50% or less and which are accounted for under the equity method. In connection with its electric generation business, NRG Energy also produces thermal energy for sale to customers, principally through steam and chilled water facilities. NRG Energy also collects methane gas from landfill sites, which is then used for the generation of electricity. In addition, NRG Energy sells small amounts of natural gas and oil to third parties. NRG Energy's wholly owned subsidiary, NRG Power Marketing, Inc. enters into both physical and financial transactions on behalf of the entities which own the electric generating plants in order to optimize the financial performance of the plants. Electrical energy revenue is recognized upon transmission to the customer. Capacity and ancillary revenue is recognized when contractually earned. Disputed revenues are not recorded on the financial statements and will not be recognized as income until disputes are resolved and collection is assured. NRG Energy also performs operations and maintenance services for some of the projects in which it has an interest. Revenue is recognized as service contract revenue on these contracts when the services are performed. NRG Energy uses the equity method of accounting to recognize as revenue its pro rata share of the net income or loss of the unconsolidated investment until such time as the company's investment is reduced to zero, at which time equity income is generally recognized only upon receipt of cash distributions from the investee. NRG Energy recognizes other income for interest income on loans to affiliates as the interest is earned and realizable. 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 cash flows 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 and are not included in the determination of the results of operations. 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, notes receivable and derivative instruments 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 59

Energy believes the credit risk posed by industry concentration is offset by the diversification and creditworthiness of its customer base. See Note 17. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amount of cash and cash equivalents, receivables, accounts payables, and accrued liabilities approximate fair value because of the short maturity of these instruments. The carrying amounts of long-term receivables approximate fair value as the effective rates for these instruments are comparable to market rates at year end, including current portions. The carrying amount of long term debt was approximately $8.3 billion and $3.8 billion at December 31, 2001 and 2000, respectively. The estimated fair value of long-term debt is based on borrowing rates currently available with similar terms and average maturities. STOCK BASED COMPENSATION In 1995, the Financial Accounting Standard Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 123, "Accounting for Stock Based Compensation." NRG Energy has elected to continue to account for stock-based compensation using the intrinsic value method prescribed in Accounting Principle Board Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, NRG Energy records expense in an amount equal to the excess of the quoted market price on the grant date over the option price. Such expense is recognized at the grant date for options fully vested. For options with a vesting period, the expense is recognized over the vesting period. NRG Energy has recognized approximately $1.9 million and $7.3 million of stock based compensation expense for the periods ended December 31, 2001 and 2000, respectively. NET INCOME PER SHARE Basic net income per share is calculated based on the weighted average of common shares outstanding during the period. Net income per share, assuming dilution is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding. NRG Energy's only common equivalent shares are those that result from dilutive common stock options and NRG Energy's Corporate Units (see Note 15). 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, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. 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, un-collectible accounts and actuarially determined benefit costs and the valuation of long-term energy commodities contracts, 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 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized but instead be tested for impairment in accordance with SFAS No. 121, "Accounting for the Impairment of Long-lived assets and for Long-lived Assets to Be Disposed Of." Goodwill will no longer be amortized to comply with the provisions of SFAS No. 142. Instead, goodwill and intangible assets that will not be amortized should be tested for impairment annually and on an interim basis if an event occurs or a circumstance changes between annual tests that may reduce the fair value of a reporting unit below its carrying value. An impairment test is 60

required to be performed within six months of the date of adoption, and the first annual impairment test must be performed in the year the statement is initially adopted. NRG Energy and its subsidiaries, as required, adopted SFAS No. 142 on January 1, 2002. At December 31, 2001, NRG Energy had intangible assets of $97.1 million, including $56.6 million of goodwill. These amounts and all intangible assets and goodwill acquired in the future will be accounted for under the new accounting standard. The new accounting standard is expected to initially increase earnings by an immaterial amount due to the elimination of regular amortization expense, but occasionally cause reductions in earnings when impairment write-downs of goodwill and/or intangible assets are required. Expense recognized for amortization of goodwill in 2001 was $3.8 million (pre-tax). NRG Energy does not expect to recognize any asset impairments as a result of adopting SFAS No. 142 in the first quarter of 2002. In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." This statement addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. SFAS No. 143 requires an entity to recognize the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Upon initial recognition of a liability for an asset retirement obligation, an entity shall capitalize an asset retirement cost by increasing the carrying amount of the related long-lived asset by the same amount as the liability. SFAS No. 143 is effective for financial statements issued for fiscal years beginning after June 15, 2002. NRG Energy has not completed its analysis of SFAS No. 143. In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This statement addresses financial accounting and reporting for the impairment or disposal of long-lived assets. SFAS No. 144 retains and expands upon the fundamental provisions of existing guidance related to the recognition and measurement of the impairment of long-lived assets to be held and used and the measurement of long-lived assets to be disposed of by sale. Generally, the provisions of SFAS No. 144 are effective for financial statements issued for fiscal years beginning after December 15, 2001. 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 During the year ended December 31, 2001, NRG Energy completed numerous acquisitions. These acquisitions have been recorded using the purchase method of accounting. Accordingly, these purchase prices have been preliminarily allocated to assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. These estimates may be adjusted based upon completion of certain procedures including third party valuations. Operations of the acquired companies have been included in the operations of NRG Energy since the date of the respective acquisitions. In January 2001, NRG Energy purchased from LS Power, LLC a 5,339 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. 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. In March 2001, NRG Energy purchased from Cogentrix the remaining 430 MW, or 51.37% interest, in an 837 MW natural gas-fired combined-cycle plant in Batesville, Mississippi. NRG Energy acquired a 48.63% interest in the plant in January 2001 from LS Power. In June 2001, NRG Energy purchased a 640 MW natural gas-fired power plant in Audrain County, Missouri from Duke Energy North America LLC. In June 2001, NRG Energy closed on the construction financing for the Brazos Valley generating facility, a 633 MW gas-fired power plant in Fort Bend County, Texas that NRG Energy will build, operate and 61

manage. At the time of the closing, NRG Energy also became the 100% owner of the project by purchasing STEAG Power LLC's 50% interest in the project. NRG Energy expects the project to begin commercial operation in February 2003. In June 2001, NRG Energy purchased 1,081 MW of interests in power generation plants from a subsidiary of Conectiv. NRG Energy acquired a 100% interest in the 784 MW coal-fired Indian River Generating Station located near Millsboro, Delaware and in the 170 MW oil-fired Vienna Generating Station located in Vienna, Maryland. In addition, NRG Energy acquired 64 MW of the 1,711 MW coal-fired Conemaugh Generating Station located approximately 60 miles east of Pittsburgh, Pennsylvania and 63 MW of the 1,711 MW coal-fired Keystone Generating Station located approximately 50 miles east of Pittsburgh, Pennsylvania. In June 2001, NRG Energy purchased a 389 MW gas-fired power plant and a 116 MW thermal power plant, both of which are located on Csepel Island in Budapest, Hungary, from PowerGen. In April 2001, NRG Energy also purchased from PowerGen its interest in Saale Energie GmbH and its 33.3% interest in MIBRAG BV. By acquiring PowerGen's interest in Saale Energie, NRG Energy increased its ownership interest in the 960 MW coal-fired Schkopau power station located near Halle, Germany from 200 MW to 400 MW. By acquiring PowerGen's interest in MIBRAG, an integrated energy business in eastern Germany consisting primarily of two lignite mines and three power stations, and following MIBRAG's buy back of the shares NRG Energy acquired from PowerGen, NRG Energy increased its ownership of MIBRAG from 33.3% to 50%. The Washington Group International, Inc., owns the remaining 50% of MIBRAG. In August 2001, NRG Energy acquired an approximately 2,255 MW portfolio of operating projects and projects in advanced development, including projects that NRG Energy intends to develop, that are located in Illinois and upstate New York from Indeck Energy Services, Inc. In August 2001, NRG Energy acquired Duke Energy's 77% interest in the approximately 520 MW natural-gas fired McClain Energy Generating Facility located near Oklahoma City, Oklahoma. The Oklahoma Municipal Power Authority owns the remaining 23% interest. The McClain facility commenced operations in June 2001. In September 2001, NRG Energy acquired a 50% interest in TermoRio SA, a 1,040 MW gas-fired cogeneration facility currently under construction in Rio de Janeiro State, Brazil, from Petroleos Brasileiros SA (Petrobras). Commercial operation of the facility is expected to begin in March 2004. NRG Energy has the option to put its interest in the project back to Petrobras after March 2002 if by that time certain milestones have not been met, including final agreement on the terms of all project documents. During fiscal year 2001, NRG Energy also acquired other minor interests in projects in Taiwan, India, Peru and the State of Nevada. 62

The respective purchase prices have been allocated to the net assets of the acquired entities as follows:

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 63

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 equity-method investments of 200 MW or more which were in operation at December 31, 2001 is as follows:

NOTE 7 -- RELATED PARTY TRANSACTIONS NRG Energy and Xcel Energy have entered into material transactions and agreements with one another and are expected to enter into material transactions and agreements from time to time in the future. Certain material agreements and transactions currently existing between NRG Energy and Xcel Energy are described below. OPERATING AGREEMENTS NRG Energy has two agreements with Xcel Energy for the purchase of thermal energy. Under the terms of the agreements, Xcel Energy charges NRG Energy for certain costs (fuel, labor, plant maintenance, and auxiliary power) incurred by Xcel Energy to produce the thermal energy. NRG Energy paid Xcel Energy $7.1 million, $5.5 million and $4.4 million in 2001, 2000 and 1999, respectively, under these agreements. One of these agreements expires on December 31, 2002 and the other expires on December 31, 2006. 64

NRG Energy has a renewable 10-year agreement with Xcel Energy, expiring on December 31, 2006, whereby Xcel Energy agreed to purchase refuse-derived fuel for use in certain of its boilers and NRG Energy agrees to pay Xcel Energy a burn incentive. Under this agreement, NRG Energy received $1.6 million, $1.5 million and $1.4 million from Xcel Energy, and paid $2.8 million, $2.8 million and $2.7 million to Xcel Energy in 2001, 2000 and 1999, respectively. ADMINISTRATIVE SERVICES AND OTHER COSTS NRG Energy has an administrative services agreement in place with Xcel Energy. Under this agreement NRG Energy reimburses Xcel Energy for certain overhead and administrative costs, including benefits administration, engineering support, accounting, and other shared services as requested by NRG Energy. In addition, NRG Energy employees participate in certain employee benefit plans of Xcel Energy as discussed in Note 11. NRG Energy reimbursed Xcel Energy in the amounts of $12.2 million, $5.9 million and $6.4 million, during 2001, 2000 and 1999, respectively, under this agreement.

SHORT TERM DEBT As of December 31, 2001, NRG Energy had a $500 million recourse revolving credit facility under a commitment fee arrangement that matures in March of 2002. This facility provides short-term financing in the form of bank loans and replaced an earlier facility with substantially similar terms and conditions, that matured in March 2001. At December 31, 2001, NRG Energy had $170 million outstanding under this facility. In March 2002, the revolving credit facility was terminated and was replaced with a $1.0 billion 364-day corporate-level unsecured revolving line of credit with ABN AMRO Bank N.V. as Administrative Agent. During the period ended December 31, 2001 the facility bore interest at a floating rate based on LIBOR and Prime rates throughout the period and had a weighted average interest rate of 5.89%. As of December 31, 2001, NRG Energy, through its wholly owned subsidiary, NRG South Central Generating LLC, had outstanding approximately $40 million under a project level, non-recourse revolving credit agreement which matures in March 2002. During the period ended December 31, 2001, the weighted average interest rate of such outstanding advances was 4.46%. The maximum available under this facility is $40 million. NRG Energy intends to renew this facility with a facility having substantially similar terms and conditions. In January 2001, NRG Energy entered into a bridge credit agreement with a final maturity date of December 31, 2001. Approximately $600 million was borrowed under this facility to partially finance NRG Energy's acquisition of the LS Power generation assets. In March 2001, the bridge credit facility was repaid with proceeds from NRG Energy's offering of common stock and equity units. In June 2001, NRG Energy entered into a $600 million term loan facility. The facility is unsecured and provides for borrowings of base rate loans and Eurocurrency loans. The facility terminates on June 21, 2002. As of December 31, 2001, the aggregate amount outstanding under this facility was $600 million. During the period ended December 31, 2001 the weighted average interest rate of such outstanding advances was 3.94%. NRG Energy repaid this facility in March 2002, in connection with the closing of its new $1.0 billion unsecured corporate-level revolving line of credit and the receipt of $300 million of cash from Xcel Energy. NRG Energy had $170 million and $63 million in outstanding letters of credit as of December 31, 2001 and 2000, respectively. LONG-TERM DEBT AND CAPITAL LEASES In May 2001, NRG Energy's wholly-owned subsidiary, NRG Finance Company I LLC, entered into a $2 billion revolving credit facility. The facility will be used to finance the acquisition, development and construction of power generating plants located in the United States and to finance the acquisition of turbines for such facilities. The facility provides for borrowings of base rate loans and Eurocurrency loans and is secured by mortgages and security agreements in respect of the assets of the projects financed under the facility, pledges of the equity interests in the subsidiaries or affiliates of the borrower that own such projects, and by guaranties from each such subsidiary or affiliate. Provided that certain conditions are met that assure the lenders that sufficient security remains for the remaining outstanding loans, the borrower may repay loans 67

relating to one project and have the liens relating to that project released. Loans that have been repaid may be re-borrowed, as permitted by the terms of the facility. The facility terminates on May 8, 2006. The facility is non-recourse to NRG Energy other than its obligation to contribute equity at certain times in respect of projects and turbines financed under the facility. As of December 31, 2001, the aggregate amount outstanding under this facility was $697.5 million. During the period ended December 31, 2001, the weighted average interest rate of such outstanding advances was 4.83%. As part of NRG Energy's acquisition of the LS Power assets in January 2001, NRG Energy, through its wholly owned subsidiary, LSP Kendall Energy LLC, has acquired a $554.2 million credit facility. The facility is non-recourse to NRG Energy and consists of a construction and term loan, working capital and letter of credit facilities. As of December 31, 2001, there were borrowings totaling approximately $499.5 million outstanding under the facility at a weighted average annual interest rate of 5.12%. Upon the acquisition of the LS Power assets, NRG Energy assumed approximately $326 million of bonds outstanding originally issued to finance the construction of the Batesville generation plant. In May 1999, LSP Energy Limited Partnership (Partnership) and LSP Batesville Funding Corporation (Funding) issued two series of Senior Secured Bonds (Bonds) in the following total principle amounts: $150 million 7.16% Series A Senior Secured Bonds due 2014 and $176 million 8.160% Series B Senior Secured Bonds due 2025. Interest is payable semiannually on each January 15 and July 15. In March 2000, a registration statement was filed by Partnership and Funding and became effective. The registration statement was filed to allow the exchange of the Bonds for two series of debt securities (Exchange Bonds), which are in all material respects substantially identical to the Bonds. The Exchange Bonds are secured by substantially all of the personal property and contract rights of the Partnership and Funding. The Exchange Bonds are redeemable, at the option of Partnership and Funding, at any time in whole or from time to time in part, on not less than 30 nor more than 60 days prior notice to the holders of that series of Exchange Bonds, on any date prior to their maturity at a redemption price equal to 100% of the outstanding principal amount of the Exchange Bonds being redeemed and a make whole premium. In no event will the redemption price ever be less than 100% of the principal amount of the Exchange Bonds being redeemed plus accrued and unpaid interest thereon. Principal payments are payable on each January 15 and July 15 beginning July 15, 2001. On March 13, 2001, NRG Energy completed the sale of 11.5 million equity units for an initial price of $25 per unit. The 11.5 million equity units sold included 1.5 million units sold pursuant to the underwriters' over-allotment option. NRG Energy received gross proceeds from the issuance of $287.5 million. Net proceeds from this issuance were $278.4 million after deducting underwriting discounts, commissions and estimated offering expenses. Each equity unit initially consists of a corporate unit comprising a $25 principal amount of NRG Energy's senior debentures and an obligation to acquire shares of NRG Energy common stock no later than May 18, 2004 at a price ranging from between $27.00 and $32.94. Approximately $4.1 million of the gross proceeds have been recorded as additional paid in capital to reflect the value of the obligation to purchase NRG Energy's common stock. Interest payments will be payable on the debentures quarterly in arrears on each February 16, May 16, August 16 and November 16, commencing May 16, 2001. Interest will be payable initially at an annual rate of 6.50% of the principal amount of $25 per debenture to, but excluding, February 17, 2004, or May 18, 2004 if the interest rate is not reset three business days prior to February 17, 2004 or three business days prior to May 18, 2004, the debentures will bear interest from February 17, 2004, or May 18, 2004, as applicable, at the reset rate to, but excluding, May 16, 2006. In addition, original issued discount will accrue on the debentures. The net proceeds were used in part to reduce amounts outstanding under NRG Energy's $600 million short-term bridge credit agreement, which was used to finance in part NRG Energy's acquisition of LS Power generation assets. In March 2001, NRG Energy increased its ownership interest in PERC, which resulted in the consolidation of its equity investment in PERC. As a result, the assets and liabilities of PERC became part of the assets and liabilities of NRG Energy. Upon completion of the transaction, NRG Energy recorded approximately $37.9 million of outstanding Finance Authority of Maine (FAME) Electric Rate Stabilization Revenue Refunding Bonds Series 1998 (FAME bonds) which were issued on PERC's behalf by FAME in June 1998. The face amount of the bonds that were initially issued was approximately $44.9 million and was used to repay the Floating Rate Demand Resource Revenue Bonds issued by the Town of Orrington, Maine 68

on behalf of PERC. The FAME bonds are fixed rate bonds with yields ranging from 3.75% to 5.2%. The weighted average yield on the FAME bonds is approximately 5.1%. The FAME bonds are subject to mandatory redemption in annual installments of varying amounts through July 1, 2018. Beginning July 1, 2008 the FAME bonds are subject to redemption at the option of PERC at a redemption price equal to 102% through June 30, 2009, 101% for the period July 1, 2009 to June 30, 2010 and 100% thereafter, of the principal amount outstanding, plus accrued interest. The loan agreement with FAME contains certain restrictive covenants relating to the FAME bonds, which restrict PERC's ability to incur additional indebtedness, and restricts the ability of the general partners to sell, assign or transfer their general partner interests. The bonds are collateralized by liens on substantially all of PERC's assets. In April 2001, NRG Energy issued $690 million of senior notes in two tranches. The first tranche of $350 million matures in April 2011 and bears an interest rate of 7.75%. The second tranche of $340 million matures in April 2031 and bears an interest rate of 8.625%. Interest on the notes is due semi-annually each April and October. The net proceeds of the issuance were used for repayment of short-term indebtedness incurred to fund acquisitions, for investments, general corporate purposes and to provide capital for future planned acquisitions. On June 22, 2001, NRG MidAtlantic Generating LLC (MidAtlantic), a wholly owned subsidiary of NRG Energy, borrowed approximately $420.9 million under a five year term loan agreement (Agreement) to finance, in part, the acquisition of certain generating facilities from Conectiv. The Agreement terminates in November 2005 and provides for a total credit facility of $580 million. Interest is payable quarterly. The debt is guaranteed by MidAtlantic and its wholly owned subsidiaries. The Agreement provides for a variable interest rate at either the higher of the Prime rate or the Federal Funds rate plus 0.50%, or the London Interbank Offered Rate (LIBOR) of interest. During the period ended December 31, 2001, the weighted average interest rate for amounts outstanding under the Agreement was 4.56%. MidAtlantic is obligated to pay a commitment fee of 0.375% of the unused portion of the credit facility. The Agreement requires MidAtlantic to comply with certain covenants concerning limitations on additional borrowings, sales of assets, capital expenditures, and payment of dividends or other distributions to shareholders. In June 2001, in connection with NRG Energy's acquisition of the Csepel facilities, NRG Energy assumed a non-recourse credit facility agreement that provides for borrowings of approximately $78.5 million and DEM 203.6 million. As of December 31, 2001, there exists an outstanding balance of approximately $169.7 million under this credit facility. The facility terminates in 2017 with principle payments due quarterly in varying amounts throughout the term of the agreement. Interest is payable quarterly at a variable rate. In June 2001, NRG Energy through its wholly owned subsidiaries, Brazos Valley Energy LP and Brazos Valley Technology LP, entered into a $180 million non-recourse construction credit facility to fund the construction of the 600 MW Brazos Valley gas-fired combined cycle merchant generation facility located in Fort Bend County, Texas. As of December 31, 2001, there exists an outstanding balance of $159.8 million under this credit agreement. The weighted average interest rate as of December 31, 2001 was 4.61%, interest is payable quarterly. In connection with NRG Energy's acquisition of the COBEE facilities, NRG Energy recorded on its balance sheet approximately $56.3 million of non-recourse long-term debt that is due in 18 semi-annual installments of varying amounts beginning January 31, 1999 and ending July 31, 2007. The loan agreement provides an A Loan of up to $30 million and a B Loan of up to $45 million. Interest is payable semi-annual in arrears at a rate equal to 6-month LIBOR plus a margin of 4.5% on the A Loan and 6-month LIBOR plus a margin of 4.0% on the B Loan. The A Loan and the B Loan are collateralized by a mortgage on substantially all of COBEE's assets. In August 2001, NRG Energy entered into a 364-day term loan of up to $296 million. The credit facility was structured as a senior unsecured loan and was partially non-recourse to NRG Energy. The proceeds were used to finance the McClain generating facility acquisition. In November 2001, the credit facility was repaid from the proceeds of a $181.0 million term loan and $8.0 million working capital facility entered into by NRG McClain LLC, with Westdeutsche Landesbank Girozentrale, New York branch, as agent (non-recourse to NRG Energy). The final maturity date of the facility is November 30, 2006. As of December 31, 2001, the 69

aggregate amount outstanding under this facility was $159.9 million. During the period ended December 31, 2001, the weighted average interest rate of such outstanding borrowings was 5.07%. In connection with NRG Energy's acquisition of the Audrain facilities, NRG Energy has recognized a capital lease on its balance sheet within long-term debt in the amount of $239.9 million, as of December 31, 2001. The capital lease obligation is recorded at the net present value of the minimum lease obligation payable. The lease terminates in May 2023. NRG Energy will make interest payments only over the term of the lease and no principal payments until the end of the lease term. In addition, NRG Energy has recorded in notes receivable, an amount of approximately $239.9 million, which represents its investment in the bonds that the county of Audrain issued to finance the project. In connection with NRG Energy's purchase of PowerGen's interest in Saale Energie GmbH, NRG Energy has recognized a non-recourse capital lease on its balance sheet within long-term debt in the amount of $311.9 million, as of December 31, 2001. The capital lease obligation is recorded at the net present value of the minimum lease obligation payable over the lease's remaining period of 20 years. In addition, a direct financing lease was recorded in notes receivable in the amount of approximately $318.9 million. The NRG Energy Center, Inc. notes are secured principally by long-term 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, 2001. The NRG Energy senior notes are unsecured and are used to support equity requirements for projects acquired and in development. Interest is 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, 2001. The Camas Power Boiler LP notes are secured principally by its long-term assets. In accordance with the terms of the note agreements, Camas Power Boiler LP is required to maintain compliance with certain financial covenants primarily related to incurring debt, disposing of assets, and affiliate transactions. Camas Power Boiler was in compliance with these covenants at December 31, 2001. The Crockett Corporation term loan is secured primarily by the long-term assets of the Crockett Cogeneration project. Crockett is required to maintain compliance with certain financial covenants primarily related to incurring debt, disposing of assets and complying with the terms of the contract to sell energy, capacity and steam to Pacific Gas & Electric and its other customer. Crockett was in compliance with these covenants at December 31, 2001, but the bankruptcy of Pacific Gas & Electric, the counterparty on a material contract that provides security to the lenders, gives rise to a situation that could result in the acceleration of the loan. The Crockett partnership has been working with the lenders to resolve this issue, and it is the view of NRG Energy management that the lenders will not exercise their right to accelerate this loan. 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. Interest and principal payments are due quarterly. The bonds are jointly and 70

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 inter-company notes between NRG Northeast and the guarantors. 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, 2001, there remains $610 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 (pounds)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, or redeemed by NRG Energy. 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, 2000) for purposes of financing the acquisition of the Killingholme facility and (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 Killingholme facility. The final maturity date of the facility is the earlier of June 30, 2019, or the date on which all borrowings and commitments under the largest tranche of the term facility have been repaid or cancelled. In March 2000, NRG South Central Generating LLC, an indirect wholly owned subsidiary of NRG Energy, issued $800 million of senior secured bonds in a two-part offering, to finance its acquisition of the Cajun generating facilities. The first tranche was for $500 million with a coupon of 8.962% and a maturity of 2016. The second tranche was for $300 million with a coupon of 9.479% and a maturity of 2024. Interest and principal payments are due quarterly. The bonds are secured by a security interest in NRG Central U.S. LLC's and South Central Generating Holding LLC's membership 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 inter-company notes between it and Louisiana Generating, and a revenue account and a debt service reserve account. In January 2001, NRG South Central Generating LLC exchanged all of its outstanding bonds for bonds registered under the Securities Act of 1933. As of December 31, 2001, there remains $763.5 million of outstanding bonds. In September 2000, Flinders Power Finance Pty, an Australian wholly owned subsidiary, entered into a twelve year AUD $150 million promissory note (US $81.4 million at September 2000). The interest has a fixed and variable component. At December 31, 2001, the effective interest rate was 5.89% and is paid semi annually. In December 2000, NRG Energy filed a shelf registration with the SEC to issue up to $1,650.0 million of an indeterminate amount of debt securities, preferred stock, common stock, depository shares, debt warrants, stock purchase contracts, stock purchase units and hybrid securities. This shelf registration includes $150 million of securities that were carried forward from NRG Energy's previous shelf registration filed in December 1999. In June 2001, NRG filed a shelf registration with the SEC to sell up to $2 billion in debt securities, common and preferred stock, warrants and other securities. NRG expects to use the net proceeds of offering under the shelf for general corporate purposes, which may include the financing and development of new facilities, working capital and debt reduction. In July 2001, NRG Energy completed the sale of $500 million of unsecured senior notes under this shelf registration. The senior notes were issued in two tranches, the first tranche of $340 million of 6.75% Senior Notes is due July 2006 and the second tranche of $160 million of 8.625% Senior Notes is due April 2031. Interest payments are due semi-annually on January 15 and July 15 71

until maturity for the Senior Notes due 2006 and April 1 and October 1 until maturity for the Senior Notes due 2031. NRG received net proceeds from the sale of both series of notes of approximately $505.2 million, including interest on the senior notes due 2031, accrued from April 5, 2001. The net proceeds were used to repay all amounts outstanding under NRG's revolving credit agreement and for investments and other general corporate purposes and to provide capital for planned acquisitions. Annual maturities of long-term debt and capital leases for the years ending after December 31, 2001 are as follows:

(THOUSANDS OF DOLLARS) TOTAL - ---------------------- ---------- 2002........................................................ $ 500,154 2003........................................................ 159,095 2004........................................................ 160,829 2005........................................................ 908,435 2006........................................................ 1,189,538 Thereafter.................................................. 5,425,935 ---------- Total.................................................. $8,343,986

Total accumulated amortization related to the assets recorded with respect to NRG Energy's capital leases at December 31, 2001 was $0. NRG ENERGY CREDIT RATING NRG Energy's unsecured credit rating is BBB- from Standard & Poor's and Baa3 from Moody's Investors Service. In December 2001, Moody's placed NRG Energy's credit rating on review for potential downgrade. NRG Energy's credit rating remains under review by Moody's for potential downgrade. As of December 31, 2001, and 2000, NRG Energy's off-balance sheet obligations pursuant to its guarantees of performance, equity and indebtedness obligations of its subsidiaries totaled approximately $721.7 million and $493 million, respectively. NRG Energy is directly liable for the obligations of certain of its project affiliates and other subsidiaries pursuant to guarantees relating to certain of their indebtedness, equity and operating obligations. In addition, in connection with the purchase and sale of fuel emission credits and power generation products to and from third parties with respect to the operation of some of NRG Energy's generation facilities in the United States, NRG Energy may be required to guarantee a portion of the obligations of certain of its subsidiaries. If Moody's or Standard & Poor's were to downgrade NRG Energy, many of the corporate guarantees and commitments currently in place would need to be supported with letters of credit or cash collateral within 5 to 30 days. 72

As of December 31, 2001, the amount of collateral required, if NRG Energy were downgraded, was approximately $960 million to satisfy certain of the above mentioned guarantees and certain obligations associated with the $2 billion construction/acquisition revolver. Of the $960 million in collateral that could be required, approximately $200 million relates to NRG Energy's guarantees of debt service reserve accounts required by some of its project-level financings, approximately $400 million relates to NRG Energy's power marketing activities; and $360 million would be required to support its Contingent Equity Guarantee associated with the $2 billion Construction/Acquisition Revolver. Because NRG Energy places a maximum amount on its guarantees in place to support power marketing activities, and because of the relatively small number of margin accounts in place, even very large changes in market conditions would not have a material impact on the approximately $400 million of collateral that would be required for NRG Power Marketing in the event of a downgrade. In the event of a downgrade, NRG Energy would expect to meet its collateral obligations with cash on hand, available credit lines provided under its revolving line of credit, liquidity support from Xcel Energy and potentially from the issuance of debt into capital markets. Xcel Energy has stated its plan to infuse $600 million of equity into NRG Energy in 2002 in connection with its exchange offer and merger. Of this amount, $300 million has already been provided (March 2002) in the form of a convertible subordinated note that Xcel Energy has said it will cancel if its exchange offer and merger are completed. If the offer and merger are not completed, Xcel Energy has said it will continue to evaluate the terms and timing of any additional investment in NRG Energy. NRG Energy's revolving line of credit is expected to be increased from $500 million to $1 billion in March 2002. In addition, NRG Energy will maintain its $125 million letter of credit facility and plans to secure an additional $125 million credit facility for total credit facilities of $1.25 billion to be available in 2002. The Contingent Equity Guarantee associated with NRG Energy's construction revolver could increase to a maximum of $850 million by the end of 2002 as NRG Energy utilizes the capacity of the Construction/ Acquisition Revolver. Therefore, the amount of collateral required by the end of 2002 could increase to $1.45 billion. NOTE 10 -- INCOME TAXES Through March 12, 2001, NRG Energy had a tax sharing agreement with its parent, Xcel Energy, that included the following significant provisions: (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 income tax computed as if the group had actually filed a separate return, 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) NRG Energy will be currently reimbursed for the tax credits it generates to the extent its tax credits are utilized in a consolidated return. Due to the 2001 public equity offering, NRG Energy and its subsidiaries will file a federal income tax return separate from Xcel Energy for the period March 13, 2001 through December 31, 2001. This 73

deconsolidation for tax purposes has had no material impact on current or deferred taxes recorded for NRG Energy. The provision (benefit) for income taxes for the years ended December 31, consists of the following:

2001 2000 1999 -------- -------- -------- (THOUSANDS OF DOLLARS) Current U.S.................................................... $ 29,301 $ 89,020 $ 4,661 Foreign................................................ 7,149 (614) 4,040 -------- -------- -------- 36,450 88,406 8,701 -------- -------- -------- Deferred U.S.................................................... 31,773 31,311 (6,693) Foreign................................................ 13,969 7,104 (7,668) -------- -------- -------- 45,742 38,415 (14,361) Tax credits recognized...................................

The effective income tax rates for the years ended December 31, 2001 and 2000 differ from the statutory federal income tax rate of 35% as follows:
2001 2000 -------------------- --------------------- Income before income taxes........................ $298,608 $ 275,673 ======== ========= Tax at 35%........................................ 104,512 35.0% 96,486 35% State taxes (net of federal benefit).............. 7,576 2.5% 29,541 10.72% Foreign operations................................

(510) (0.2)% 11,486 4.16% -------- -------- --------- -------- Income Tax Expense................................ $ 33,404 11.2% $ 92,738 33.64% ======== ======== ========= ========
For the year ended December 31, 2001, income tax expense was $33.4 million, compared to an income tax expense of $92.7 million for the year ended December 31, 2000, a decrease of $59.3 million. The decrease in tax expense compared to 2000 was primarily due to increased IRC Section 29 energy credits, a reduction in 74

the state effective tax rate, and a higher percentage of NRG's overall earnings derived from foreign projects in lower tax jurisdictions. For the year ended December 31, 2001, NRG Energy's overall effective tax rate was 11.2%, compared to 33.6% for the same period in 2000. For the year ended December 31, 2001, NRG Energy's overall effective income tax rate before recognition of tax credits was 27.5% compared to 46.0%, for the same period in 2000. The effective income tax rate for the year ended December 31, 2000 differs from the statutory federal income tax rate of 35% primarily due to state tax, foreign tax and tax credits as shown above. 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 un-remitted earnings of foreign subsidiaries of approximately $346 million and $238 million at December 31, 2001 and 2000, respectively. The additional U.S. income tax and foreign withholding tax on the un-remitted 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 Substantially all of NRG Energy's employees participate in defined benefit pension plans. The majority of the employees participate in Xcel Energy's noncontributory, defined benefit pension plan which was formerly sponsored by NSP. Other employees participate in noncontributory, defined benefit pension plans that are sponsored by NRG Energy or NRG Energy affiliates. Benefits are generally based on a combination of an employee's years of service and earnings. Some formulas also take into account Social Security benefits. Plan assets principally consist of the common stock of public companies, corporate bonds and U.S. government securities. In addition, NRG Energy provides postretirement health and welfare benefits (health care and death benefits) for certain groups of its employees. Generally, these are groups that were acquired in recent years and for whom prior benefits are being continued (at least for a certain period of time or as required by union contracts). Cost sharing provisions vary by acquisition group and terms of any applicable collective bargaining agreements. Certain former NRG retirees are covered under the legacy Xcel plan, which was terminated for non-bargaining employees retiring after 1998 and for bargaining employees retiring after 1999. Xcel's pension and other postretirement health and welfare benefit obligations and assets/(liability) at December 31, 2001 and 2000 were as follows:

NRG Energy participates in Xcel Energy's defined contribution 401(K) plan that covers substantially all employees. Total contributions to the plan were approximately $1.7 million, $1.1 million and $0.5 million for the years ended December 31, 2001, 2000 and 1999, 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 NRG Energy 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 Energy'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 2001, 2000 and 1999, NRG Energy recorded compensation expense of approximately $0, $6.0 million and $13.0 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). 401(K) PLANS NRG Energy also assumed several contributory, defined contribution employee savings plans as a result of its 2000 and 1999 acquisition activity. These plans comply with Section 401(k) of the Internal Revenue Code and cover substantially all of our employees who are not covered by Xcel Energy's 401(k) Plan. NRG Energy matches specified amounts of employee contributions to the plan. Employer contributions made to these plans were approximately $1.5 million, $1.1 million and $0.3 million in 2001, 2000 and 1999, respectively. PENSION AND OTHER BENEFITS -- 2001 ACQUISITIONS During 2001, NRG Energy acquired several generating assets and assumed benefit obligations for a number of employees associated with those acquisitions. The plans assumption included noncontributory defined benefit pension plans, matched 401(k) savings plans, and contributory post-retirement welfare plans. Of the 2001 acquisitions where these obligations were assumed, approximately 79% percent of such employees are represented by one local union under collective bargaining agreements, which expire on July 1, 2004. Plan liability and expense amounts for these acquisitions are included in the pension and postretirement health care amounts shown above. PENSION AND OTHER BENEFITS NRG Energy assumed the Hsin Yu Energy Development Co., LTD. defined pension obligation upon NRG Energy's approximate 60% acquisition of Hsin Yu Development Co. LTD during fiscal year 2001. The approximate net periodic benefit cost for the year related to this plan was $0.07 million. NRG Energy also assumed the pension obligation related to Killingholme due to NRG Energy's acquisition of the gas-fired combined cycle, baseload facility in March of 2000. Pension costs relating to this plan for FY 2001 were approximately $0.5 million. NOTE 12 -- SALES TO SIGNIFICANT CUSTOMERS During 2001, sales to two customers accounted for 26.7% and 13.8% of total revenues from majority owned operations in 2001. During 2000, sales to two customers accounted for 22.2% and 12.2% of total 77

revenues from majority owned operations in 2000. Sales to three customers accounted for 21.0%, 19.7% and 10.5% of total revenues from majority owned operations in 1999. NOTE 13 -- FINANCIAL INSTRUMENTS The estimated December 31 fair values of NRG Energy's recorded financial instruments are as follows:

2001 2000 ------------------------ ----------------------- CARRYING FAIR CARRYING FAIR AMOUNT VALUE AMOUNT VALUE ---------- ---------- ---------- --------- (IN THOUSANDS) Cash and Cash equivalents...................... $ 186,107 $ 186,107 $ 95,243 $ 95,243 Restricted cash................................ 161,842 161,842 12,135 12,135 Notes receivable, including current portion.... 777,602 777,602 77,012 77,012 Long-term debt, including current portion...... 8,343,986 8,217,452 3,797,318 3,838,627
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 At December 31, 2001 and 2000, NRG Energy had various foreign currency exchange instruments with combined notional amounts of $46.3 million and $8.8 million, respectively. These foreign currency exchange instruments were hedges of expected future cash flows. If the hedges had been terminated at December 31, 2001 and 2000, NRG Energy would have owed the counterparties $2.4 million and $0.7 million, respectively. Interest rates At December 31, 2001 and 2000, NRG Energy had various interest-rate swap agreements with combined notional amounts of $2.4 billion and $530 million, respectively. These contracts are used to manage NRG Energy's exposure to changes in interest rates. If these swaps had been terminated at December 31, 2001 and 2000, NRG Energy would have owed the counterparties $81.5 million and $28.9 million, respectively. Energy related commodities At December 31, 2001 and 2000 NRG Energy had various energy related commodities financial instruments with combined notional amounts of $1.0 billion and $309.0 million, respectively. These financial instruments take the form of fixed price, floating price or indexed sales or purchases, and options, such as puts, calls, basis transactions and swaps. These contracts are used to manage NRG Energy's exposure to commodity price variability in electricity, emission allowances and natural gas, oil and coal used to meet fuel requirements. If these contracts were terminated at December 31, 2001 and 2000, NRG Energy would have received $224.1 million and $52.8 million from counterparties, respectively. Credit Risk Management believes that NRG Energy's exposure to credit risk due to nonperformance by the counter-parties to its hedging contracts is insignificant, based on the investment grade rating of the counterparties. Counter-parties consist principally of financial institutions and major energy companies. NRG Energy actively manages its exposure to counter-party risk. NRG Energy has an established credit policy in place to minimize overall credit risk. Important elements of this policy include ongoing financial reviews of all counterparties, established credit limits, as well as monitoring, managing and mitigating credit exposure. 78

Enron Bankruptcy During the fourth quarter of 2001, NRG Energy recorded a net after-tax expense of approximately $6.7 million related to Enron Corp.'s bankruptcy. This amount includes a $14.2 million after-tax charge to establish bad debt reserves, which was partially offset by a $7.5 million after-tax gain on a credit swap agreement entered into as part of NRG Energy's credit risk management program. NRG Energy has fully provided for its exposure to Enron; however, as with any receivable, NRG Energy will pursue collection of all amounts outstanding through the ordinary course of business. In addition, an Enron subsidiary, NEPCO, is serving as the construction contractor for two greenfield development projects, the Kendall and Nelson projects (2,336 MW combined) currently under construction in Illinois. Enron guaranteed NEPCO's obligations under the construction contracts. To date, the actual construction and engineering work on both projects has continued without disruption and NRG Energy expects the projects to achieve commercial operations on schedule. NRG Energy believes its overall construction costs for these two projects will increase by approximately $22 per kilowatt, as a result of the need to restructure the underlying construction contracts following the Enron bankruptcy. NOTE 14 -- CAPITAL STOCK SALE OF STOCK In March 2001, NRG Energy completed the sale of 18.4 million shares of common stock for an initial price of $27 per share. The offering was completed with all 18.4 million shares of common stock being sold including the over-allotment shares of 2.4 million. NRG Energy received gross proceeds from the issuance of $496.6 million. Net proceeds from the issuance were $473.4 million after deducting underwriting discounts, commissions and estimated offering expenses. The net proceeds were used in part to reduce amounts outstanding under NRG Energy's short-term bridge credit agreement, which was used to finance in part NRG Energy's acquisition of the LS Power assets. At December 31, 2001, there were approximately 50,939,875 shares of common stock, and 147,605,000 shares of Class A common stock issued and outstanding. In June 2000, NRG Energy sold 32.4 million shares of common stock at $15 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 was approved by shareholders in June 2001 and which will be administered by 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, independent directors and employees under the plan. 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 market value of the stock at the date of grant, if any, of each option on the date of grant is recorded as compensation expense over a vesting period. Options granted prior to June 2001 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. Options granted in June 2001 and subsequently, vest over a four year period, with 25% vesting each year and generally expire ten years from the date of grant. The board's independent directors' options vested immediately upon being granted. The average exercise price of vested options at December 31, 2001 and 2000 was $14.39 and $9.51, respectively, all of which were granted in replacement of units previously outstanding under the equity plan. Compensation expense related to options granted totaled $1.9 million and $7.3 million, for the year ended December 31, 2001 and 2000, respectively. 79

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. Stock option transactions were (shares in thousands):

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model, with the following weighted-average assumptions used for grants in 2001 and 2000.
2001 2000 ----- ----- Dividends per year.......................................... -- -- Expected volatility......................................... 60.54 50.26 Risk-free interest rate..................................... 5.47 5.01 Expected life (years)....................................... 7 7
Using the Black-Scholes option-pricing model, the weighted-average fair value of NRG Energy's stock options granted for 2001 and 2000 is $13.26 and $14.38 per share, respectively. 80

NRG Energy accounts for its stock option plan in accordance with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," under which, no compensation cost has been recognized. Had compensation cost been determined consistent with SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123), NRG Energy's net income and per share amounts would have approximated the following pro forma amounts for the years ended December 31:

2001 2000 -------- -------- Net income.................................................. As reported $265,204 $182,935 Pro Forma $260,404 182,279 Earnings per share data: Basic earnings per share.................................... As reported $ 1.36 $ 1.10 Pro Forma 1.34 1.10 Diluted earnings per share.................................. As reported 1.35 1.10 Pro Forma 1.33 1.09
The effects of applying SFAS No. 123 on pro forma disclosures of net income and earnings per share for the years ended December 31, 2001 and 2000 are not likely to be representative of the pro forma effects on net income and earnings per share in future years for the following reasons: 1) the number of future shares to be issued under this plan is not known, 2) the effect of an additional year of vesting no options granted in prior years is not considered in the assumptions as of December 31, 2001 and 3) the assumptions used to determine the fair value can vary significantly. NOTE 15 -- EARNINGS PER SHARE Basic earnings per common share were computed by dividing net income by the weighted average number of Class A common stock and common stock shares outstanding during each year. Shares issued during the year are weighted for the portion of the year that they were outstanding. Diluted earnings per share is computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares that were outstanding during 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. The dilutive effect of the issuance of common stock in the future due to the outstanding warrants (11.5 million shares) to buy NRG Energy common stock issued in connection with NRG Energy's Corporate Units issuance in March 2001 is calculated using the treasury stock method. The reconciliation of basic earnings per common share to diluted earnings per share is shown in the following table (in thousands, except per share data):

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 $7.5 billion in the years 2002 through 2006. 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. FirstEnergy. In November 2001, NRG Energy signed purchase agreements to acquire or lease four coal-fired generating facilities totaling approximately 2,535 MW and two ash disposal sites from subsidiaries of FirstEnergy Corporation. The four generating facilities are located in Ohio, along the shore of Lake Erie, and are the approximately 376 MW Ashtabula facility in Ashtabula, Ohio, the approximately 249 MW Lake Shore facility in downtown Cleveland, the approximately 1,262 MW Eastlake facility near Cleveland and the approximately 648 MW Bay Shore facility near Toledo. NRG Energy is also acquiring all of the equity interests in Bay Shore Power Company, which is a subsidiary of FirstEnergy and the owner of a 136 MW petroleum coke-fired steam generating project currently undergoing testing and commissioning on the Bay Shore facility site. NRG Energy is working to close these acquisitions in the second quarter of 2002. In connection with the acquisition of these facilities, NRG Energy is entering into a Transition Power Purchase Agreement with FirstEnergy, pursuant to which NRG Energy will supply to FirstEnergy approximately 95% of the output from the facilities through 2005. 82

Conectiv. In June 2001, NRG Energy extended purchase agreements that were entered into with a subsidiary of Conectiv to acquire 794 MW of coal and oil-fired electric generating capacity and other assets in New Jersey and Pennsylvania, including an additional 66 MW of the Conemaugh Generating Station and an additional 42 MW of the Keystone Generating Station. By their terms these purchase agreements became terminable by either party after February 28, 2002, and on April 1, 2002 NRG Energy exercised its right to terminate the agreements. CALIFORNIA LIQUIDITY CRISIS NRG Energy's California generation assets include a 57.67% interest in Crockett Cogeneration, a 39.5% interest in the Mt. Poso facility and a 50% interest in the West Coast Power partnership with Dynegy. In March 2001, the California PX filed for bankruptcy under Chapter Eleven of the Bankruptcy Code, and in April 2001, Pacific Gas & Electric Company (PG&E) also filed for bankruptcy under Chapter Eleven. PG&E's filing delayed collection of receivables owed to the Crockett facility. In September 2001, PG&E filed a proposed plan of reorganization. Under the terms of the proposed plan, which is subject to challenge by interested parties, unsecured creditors such as NRG Energy's California affiliates would receive 60% of the amounts owed upon approval of the plan. The remaining 40% would be paid in negotiable debt with terms from 10 to 30 years. The California Power Exchange's (PX) ability to repay its debt is dependent on the extent to which it receives payments from PG&E and SCE. On December 21, 2001, the California bankruptcy court affirmed the Crockett Power Purchase Agreement (it had previously affirmed Mt. Poso's agreement) with PG&E and, in respect of the Crockett Power Purchase Agreement, approved a twelve-month repayment schedule of all past due amounts totaling $49.6 million, plus interest. The first payment of $6.2 million, including accrued interest, was received on December 31, 2001. NRG Energy's share of the net amounts owed to West Coast Power by the California ISO and PX totaled approximately $85.1 million as of December 31, 2001 compared to $101.8 million at December 31, 2000. These amounts reflect NRG Energy's share of (a) total amounts owed to West Coast Power less (b) amounts that are currently treated as disputed revenues and are not recorded as accounts receivable in the financial statements of West Coast Power LLC, and reserves taken against accounts receivable that have been recorded in the financial statements. The decrease is primarily attributed to cash collections from the California ISO during the fourth quarter of 2001. CONTRACTUAL COMMITMENTS In connection with the acquisition of certain generating facilities NRG Energy 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 83

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 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 liability associated with this out of the market contract in the amount of approximately $66 million in other long-term obligations and deferred income 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. During 2001, NRG Energy acquired a portfolio of projects located in Delaware, Maryland and Pennsylvania from Conectiv. Upon closing of the acquisition, NRG Energy assumed a power purchase agreement. This agreement, which is not project specific, requires NRG Energy to deliver and Conectiv to purchase 500 MW of electric energy around the clock at a specified price through 2005. The sales price of the contracted electricity was substantially lower than the fair value that the electricity on the merchant market at the date of acquisition. NRG Energy has recorded the liability associated with the out of market contract on the balance sheet in the amount of approximately $89.4 million as of December 31, 2001. Approximately $45.1 million is recorded in other current liabilities and approximately $44.3 million in other long-term obligations and deferred income. The difference will be amortized into income over the life of the agreement. ENVIRONMENTAL REGULATIONS As part of acquiring existing generating assets, NRG Energy has inherited environmental liabilities. Generally, potential liabilities are identified and researched during due diligence processes and funds are reserved in the financial pro forma to address them as circumstances dictate. Often, potential implementation plans are changed, delayed or abandoned due to one or more of the following conditions: (a) extended negotiations with regulatory agencies, (b) a delay in promulgating rules critical to dictating the design of expensive control systems, (c) changes in governmental/regulatory personnel, (d) changes in governmental priorities (i.e., events of September 11th, 2001), or (e) selection of a less expensive compliance option than originally envisioned. The following paragraphs present an update on capital investments associated with existing environmental liabilities. WEST COAST REGION Environmental expenditures at the Encina Generating Station include the installation of Selective Catalytic Reduction (SCR) emission control technology on all five units. These SCRs are mandated by the San Diego County Air Pollution Control District Rule 69 and by the December 13, 2001 Rule 69 Regular Variance Order 3732. Units 4 & 5 were retrofit with SCRs beginning in late 2001 and scheduled to end in spring 2002. SCR emission control installations on Units 1, 2 & 3 are scheduled to be phased in beginning in fall 2002 and ending in spring 2003. The cost for all five SCR retrofits is estimated at approximately $39 million. NORTHEAST REGION The total budgeted capital expenditures during the first 5 years of the Con-Ed, NIMO, Somerset and CLP assets acquired by NRG Energy were in the range of $60 million dollars. During the years 1999-2001, NRG Energy recorded approximately $4 million of expenditures on environmental matters related to inherited 84

liabilities associated with these assets. These expenditures were incurred as a result of moving forward with efforts to address NRG Energy's inherited remedial obligations, studies related to establishing strategies for complying with the NO(X) budget program, and other matters required as part of consent orders transferred to NRG Energy as part of acquisition packages. As the company progresses in its negotiations to close out consent order issues, an increased rate of expenditure is anticipated. NRG Energy estimates approximately $7.5 million to close out the remaining issues associated with remedial investigations/clean-ups at Somerset, Arthur Kill, Astoria, Middletown, Norwalk Harbor, Devon, and Montville. In response to liabilities associated with these activities, accruals have been established when reasonable estimates are possible. As of December 31, 2001 and 2000, NRG Energy has established such accruals in the amount of approximately $5.0 million and $6.0 million, respectively. 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 estimable, or when current remediation estimates are adjusted to reflect new information. During the years 2001, 2000 and 1999, NRG Energy recorded expenses of approximately $15.3 million, $3.4 million and $0.3 million of expenditures related to environmental matters, respectively. The balance of the estimated $60 million in capital expenditures over the next five years is most notably for landfill construction, installation of NO(X) controls, installation of best available technology for minimizing environmental impacts associated with impingement and entrainment of fish and larvae, particulate matter control improvements, and spill prevention controls. MID-ATLANTIC REGION Capital expenditures over the next five years related to resolving environmental concerns at the Indian River Generating Station are centered around possible closure of the existing landfill and construction of a new cell(s) to replace it, possible addition of a cooling tower, and the addition of controls to reduce NO(X) emissions. Currently, cost estimates for addressing the first two items vary widely with NRG Energy's success in selling ash and in NRG Energy's negotiations with the Delaware Natural Resources and Environment Commission (DNREC). If ash sales are poor, it is estimated that NRG Energy could spend up to $11 million over the five-year timeframe to close/construct sections of the landfill; if sales are robust, expenditures related to closure/construction are expected to be minimal. In the unlikely event NRG Energy is unable reach agreement with DNREC on extension of a variance, NRG Energy estimates a $40 million cooling tower could be required; if negotiations are successful, a cooling tower can be avoided. NRG Energy has also budgeted funds for installation of NO(X) controls at both the Indian River and Vienna Generating Stations. SOUTH CENTRAL REGION Approximately $35 million over the next five years has been budgeted for the addition of NO(X) controls to Units 1-3 at Big Cajun II; $5-10 million over the same time period is for NO(X) controls on the steam boilers at Big Cajun I. Approximately $4-5 million will be spent over the next two years to reduce particulate matter emissions during start-up of the Big Cajun II boilers and $3-5 million for expanding the existing bottom ash pond at the Big Cajun II plant site. NORTH CENTRAL REGION No capital expenditures related to environmental liabilities have been budgeted at this time. LEGAL ISSUES New York Environmental Litigation In January 2002 the New York Attorney General and the New York Department of Environmental Control filed suit in the western district of New York against NRG Energy and Niagara Mohawk Power Corporation, the prior owner of the Huntley and Dunkirk facilities in New York. The lawsuit relates to 85

physical changes made at those facilities prior to NRG Energy's assumption of ownership. The complaint alleges that these changes represent major modifications undertaken without the required permits having been obtained. 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, NRG Energy could be enjoined from operating the facilities if the facilities are found not to comply with applicable permit requirements. In July 2001, Niagara Mohawk Power Corporation filed a declaratory judgment action in the Supreme Court for the State of New York, County of Onondaga, against NRG Energy and its wholly-owned subsidiaries, Huntley Power LLC and Dunkirk Power LLC. Niagara Mohawk Power Corporation requests a declaration by the Court that, pursuant to the terms of the Assets Sales Agreement under which NRG Energy purchased the Huntley and Dunkirk generating facilities from Niagara Mohawk (the ASA), defendants have assumed liability for any costs for the installation of emissions controls or other modifications to or related to the Huntley or Dunkirk plants imposed as a result of violations or alleged violations of environmental law. Niagara Mohawk Power Corporation also requests a declaration by the Court that, pursuant to the ASA, defendants have assumed all liabilities, including liabilities for natural resource damages, arising from emissions or releases of pollutants from the Huntley and Dunkirk plants, without regard to whether such emissions or releases occurred before, on or after the closing date for the purchase of the Huntley and Dunkirk plants. NRG Energy has counterclaimed against Niagara Mohawk Power Corporation, and the parties have exchanged discovery requests. 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 in November 2000 (Pamela R. Gordon v. Reliant Energy, Inc., et al. and Ruth Hendricks v. Dynegy Power Marketing Inc., et al). NRG Energy has also been named in another suit filed in January 2001 in San Diego County and brought by three California water districts, as consumers of electricity (Sweetwater Authority v. Dynegy, Inc., et al.), and in two suits filed in San Francisco County, one 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.) and one brought by Pier 23 Restaurant as a class action (Pier 23 Restaurant v. PG&E Energy Trading, et al.). Certain NRG Energy affiliates in NRG Energy's West Coast power partnership with Dynegy (Cabrillo I and II, Long Beach Generation and El Segundo Power) have been named as defendants in a state court action in Los Angeles County (Bustamonte v. Dynegy, 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 Coordinating Council and otherwise. 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. These six civil actions brought against NRG Energy and other power generators and power traders in California have been consolidated and assigned to the presiding judge of the San Diego County Superior Court, and a pretrial conference has been scheduled for March 2002. 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. Shareholder Litigation On February 15, 2002, Xcel Energy announced its intention to commence an exchange offer to acquire all of the outstanding publicly held shares of NRG Energy. On the same day, eight separate civil actions were filed in the Court of Chancery of the State of Delaware in and for New Castle County by owners of NRG common stock, against Xcel Energy, NRG Energy, and NRG Energy's directors. The complaints contain a number of allegations, but the basic claim is that Xcel proposes to acquire the remaining ownership of NRG 86

for inadequate consideration and without full and complete disclosure of all material information, in breach of defendants' fiduciary duties. The complaints request the court to enjoin the proposed transaction and, in the event the exchange offer is consummated, to award damages to plaintiffs. 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 majority 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 disclosure and corporate charges (primarily interest expense) that have not been allocated to the operating segments.

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. Approximately $1.1 million was initially deposited in the Solid Waste Disposal Trust Fund in 1989, and $116,000 has been funded 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 liability. At December 31, 2001 and 2000, the carrying value of the trust fund investments and the related accrued decommissioning liability was approximately $4.3 million and $3.9 million, respectively. 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. 89

NOTE 21 -- ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITY On January 1, 2001, NRG Energy adopted Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS No. 133), as 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 the fair value of non-hedge derivatives will be immediately recognized in earnings. Changes in fair values of derivatives accounted for as hedges 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 (OCI) until the hedged transactions occur and are recognized in earnings. The ineffective portion of a hedging derivative instrument's change in fair value will be immediately recognized in earnings. NRG Energy also formally assesses both at inception and at least quarterly thereafter, whether the derivatives that are used in hedging transactions are highly effective in offsetting the changes in either the fair value or cash flows of the hedged item. This assessment includes all components of each derivative's gain or loss unless otherwise noted. When it is determined that a derivative ceases to be a highly effective hedge, hedge accounting is discontinued. SFAS No. 133 applies to NRG Energy's long-term power sales contracts, long-term gas purchase contracts and other energy related commodities financial instruments used to mitigate variability in earnings due to fluctuations in spot market prices, hedge fuel requirements at generation facilities and protect investments in fuel inventories. SFAS No. 133 also applies to various interest rate swaps used to mitigate the risks associated with movements in interest rates and foreign exchange contracts to reduce the effect of fluctuating foreign currencies on foreign denominated investments and other transactions. At December 31, 2001, NRG Energy had various commodity contracts extending through December 2003, and several fixed-price gas and electricity purchase contracts extending through 2018. ACCUMULATED OTHER COMPREHENSIVE INCOME The following table summarizes the effects of SFAS No. 133 on NRG Energy's Other Comprehensive Income balance as of December 31, 2001:

ENERGY INTEREST FOREIGN COMMODITIES RATE CURRENCY TOTAL ----------- -------- -------- -------- (GAINS/(LOSSES) IN $ THOUSANDS) OCI balance at December 31, 2000............. $ -- $ -- $ -- $ -- Initial adoption of SFAS No. 133........... (6,567) (16,064) -- (22,631) Unwound from OCI during period: - due to unwinding of previously deferred amounts..................................

The adoption of SFAS No. 133 on January 1, 2001, resulted in an after-tax unrealized loss of $22.6 million recorded to OCI related to previously deferred net losses on derivatives designated as cash flow hedges. During the year ended December 31, 2001, NRG Energy reclassified gains of $25.3 million from OCI to current-period earnings. This amount is recorded on the same line in the statement of operations in which the hedged item is recorded. Also during the year ended December 31, 2001, NRG Energy recorded an after-tax gain in OCI of approximately $119.0 million related to changes in the fair values of derivatives accounted for as hedges. The net balance in OCI relating to SFAS No. 133 as of December 31, 2001 was an unrecognized gain of approximately $71.1 million. NRG Energy expects $14.3 million of the deferred net gains on derivative instruments accumulated in OCI to be recognized as earnings during the next twelve months. 90

STATEMENT OF OPERATIONS The following tables summarize the effects of SFAS No. 133 on NRG Energy's statement of operations for the period ended December 31, 2001:

ENERGY RELATED COMMODITIES 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. Certain of these transactions have been designated as cash flow hedges. NRG Energy has accounted for these derivatives by recording the effective portion of the cumulative gain or loss on the derivative instrument as a component of OCI in shareholders' equity. NRG Energy recognizes deferred gains and losses into earnings in the same period or periods during which the hedged transaction affects earnings. Such reclassifications are included on the same line of the statement of operations in which the hedged item is recorded. No ineffectiveness was recognized on commodity cash flow hedges during the period ended December 31, 2001. NRG Energy's pre-tax earnings for the year ended December 31, 2001 were increased by an unrealized gain of $14.1 million associated with changes in the fair value of energy related derivative instruments not accounted for as hedges in accordance with SFAS No. 133. During the year ended December 31, 2001, NRG Energy reclassified gains of $25.8 million from OCI to current-period earnings and expects to reclassify an additional $24.2 million of deferred gains to earnings during the next twelve months on energy related derivative instruments accounted for as hedges. INTEREST RATES To manage interest rate risk, NRG Energy has entered into interest-rate swaps that effectively fix the interest payments of certain floating rate debt instruments. Interest-rate swap agreements are accounted for as cash flow hedges. The effective portion of the cumulative gain or loss on the derivative instrument is reported as a component of OCI in shareholders' equity and recognized into earnings as the underlying interest expense is incurred. Such reclassifications are included on the same line of the statement of operations in which the hedged item is recorded. No ineffectiveness was recognized on interest rate cash flow hedges during the period ended December 31, 2001. During the year ended December 31, 2001, NRG Energy reclassified losses of $0.7 million from OCI to current-period earnings and expects to reclassify $7.6 million of deferred losses to earnings during the next twelve months on interest rate swaps accounted for as hedges. 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. 91

No ineffectiveness was recognized on foreign currency cash flow hedges during the period ended December 31, 2001. NRG Energy's pre-tax earnings for the year ended December 31, 2001 were increased by an unrealized gain of $0.3 million associated with foreign currency hedging instruments not accounted for as hedges in accordance with SFAS No. 133. During the year ended December 31, 2001, NRG Energy reclassified gains of $0.2 million from OCI to current period earnings and expects to reclassify $2.2 million of deferred losses to earnings during the next twelve months on foreign currency swaps accounted for as hedges.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Under federal securities laws, NRG Energy's directors and executive officers are required to report, within specified monthly and annual due dates, their initial ownership in NRG Energy's securities and subsequent acquisitions, dispositions or other transfers of interest in such securities. NRG Energy is required to disclose whether it has knowledge that any person required to file such a report may have failed to do so in a timely manner. To the knowledge of NRG Energy, all of its directors and officers subject to such reporting obligations have satisfied their reporting obligations in full for 2001. ITEM 11 -- EXECUTIVE COMPENSATION COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION COMPENSATION PHILOSOPHY The Compensation Committee of the Board of Directors (the "Committee") consists of four members, two of which are independent. The purpose of the Committee is to, on a regular basis, review, approve, and where applicable, make recommendations to the Board of Directors concerning executive officer compensation. The Committee's philosophy regarding executive compensation is that such compensation should be directly aligned with improvements in corporate performance and increased shareholder value. The Committee's guidelines, which are intended to reflect such philosophy, include: - Providing a competitive total compensation package that enables the Company to attract and retain key executive talent. - Aligning compensation with the Company's annual and long-term business strategies and objectives. - Providing variable compensation opportunities that are directly linked to the Company's performance and shareholder return. For the fiscal year 2001, the Compensation Committee evaluated the competitiveness of its executive compensation based on information obtained by assessing data contained in the proxy statements of similar competitive power production companies. The competitive comparisons were made against a peer group of ten power generation companies. In determining the peer group, emphasis was placed on companies with non-regulated power generation operations that are reasonably similar in size to that of NRG. The Committee utilized such information to assess the Company's position in each individual aspect of executive compensation, including base salary, annual incentive compensation and long-term incentive compensation. ELEMENTS OF COMPENSATION Compensation for the Company's executive officers for the fiscal year 2001 consisted of the following elements: base salary, annual incentive compensation, and long-term incentive compensation. Base Salary. Annual base salary is designed to compensate executive officers for their sustained performance. For the fiscal year 2001, annual base salaries for executive officers were established by reviewing base pay levels for each executive's position in the peer group proxy analysis. The base salary recommendations also incorporate the executive officer's individual performance, the general contributions of the executive officer to overall corporate performance, and the level of achievement by the executive officer in respect to specific annual goals. In general, the 2001 base salary levels for executive officers, including the Chief Executive Officer, Mr. Peterson, were increased in accordance with comparable market data. The base salary amounts paid to the executive officers for the fiscal year 2001 are reflected in the salary column of the Summary Compensation Table. Annual Incentive Compensation. Annual incentive compensation is designed to compensate executive officers for satisfying certain Company goals and is determined as a percentage of each such executive officer's 97

annual base salary. Annual incentive compensation for the executive officers for the fiscal year 2001 was determined in accordance with median levels of annual incentive awards for comparable positions, as set forth in the peer group proxy analysis. For the fiscal year 2001, the target incentive for annual incentive compensation for executive officers ranged from 55% to 75% of base salary, with Mr. Peterson's target incentive being 75% of base salary. Annual incentive payout opportunities range from 0% to 200% of the target incentive. Target incentives for the executive officers for the fiscal year 2001, were based on some or all of the following factors: net income, business development and safety goals. Mr. Peterson's target incentive was based on 95% net income and 5% of safety goal. Overall the Company achieved the maximum net income and safety goal for 2001 with a net income growth of 45% from the fiscal year ending December 31, 2000. As such, Mr. Peterson received the maximum payout available for his annual incentive compensation. The annual incentive compensation paid to the executive officers for the fiscal year 2001, is reflected in the bonus column of the Summary Compensation Table. Long-Term Incentive Compensation. Prior to the completion of the Company's initial public offering and the adoption of the NRG 2000 Long-Term Incentive Compensation Plan (the "2000 Plan"), each of which occurred in May 2000, the Company offered the NRG Equity Plan (the "Equity Plan") to its executive officers and other selected employees. The Equity Plan was established in 1993 to promote the achievement of long-term financial objectives by linking the long-term incentive compensation of the employees to the achievement of value creation, as well as to attract and retain employees of outstanding competence, encourage teamwork among employees and provide employees with an opportunity for long-term capital accumulation. Under the Equity Plan, the Company made grants of "equity units", which were intended to simulate stock options. Grants of equity units were made annually at the discretion of the Board of Directors with a grant price consistent with the most recent valuation of equity units. In connection with the Company's initial public offering, the Company established the 2000 Plan, the principal components of which are non-qualified stock options. As such, the Company discontinued the Equity Plan. All outstanding, non-vested equity units for active employee participants were terminated and replaced with a comparable stock option grant. Under the 2000 Plan the Incentive Plan Subcommittee will approve a target number of option shares for each executive officer, with such targets to be based in part on proxy information and a base salary multiple to determine the long-term incentive compensation. It is intended that NRG's CEO will make a recommendation to the Incentive Plan Subcommittee as to the number of options to be granted and the Incentive Plan Subcommittee will be responsible for reviewing and approving all such recommendations and stock option grants to executive officers. Options granted will have an exercise price equal to the fair market value of the common stock of the Company on the date of grant, and typically, will be exercisable over a four-year period in increments of 25% per year. Initial grants may include a one-year waiting period prior to the vesting of such options. DISCUSSION OF COMPENSATION IN EXCESS OF $1 MILLION PER YEAR The Company has considered the implications of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), enacted under the Revenue Reconciliation Act of 1993, which precludes a public corporation from taking tax deduction for individual compensation in excess of $1 million for its Chief Executive Officer or any of its four other highest-paid officers. Additionally, the Company has considered the exemptions to such limitation, specifically for compensation that is performance based within the meaning of such Section, which are also provided in Section 162(m). In order to qualify compensation derived by executive officers from stock options as performance-based compensation, as contemplated by the Internal Revenue Service, the NRG Energy, Inc. 2000 Long-Term Incentive Compensation Plan was approved by the Board of Directors and the shareholders of the Company. Additionally, in order to qualify bonus payments to executives under Section 162(m) and preserve the deductibility of such payments, the Annual Incentive Plan for Designated Officers has been approved by the Committee, the Board, and the shareholders of the Company. 98

Regardless, in the future, the Company may award compensation to its executive officers that may not qualify under Section 162(m) as deductible compensation. The Company will continue to consider all elements of expense in providing such compensation, including the impact of Section 162(m).

DIRECTOR COMPENSATION NRG Energy does not award directors who are also employees of NRG Energy or employees of Xcel Energy any separate compensation or other consideration, direct or indirect, for service as a director. During 2001, directors not employed by NRG Energy or Xcel Energy ("Non-Employee Directors") received annual fees of $35,000 plus $1,000 for each Board of Directors meeting attended in person, $800 for each committee meeting attended in person and reasonable travel expenses. Committee chairs received an additional $200 per meeting attended in person. Non-Employee Directors participating in meetings of the Board of Directors or a committee by telephone received 50% of such meeting fees. In connection with NRG Energy's initial public offering, each of the Non-Employee Directors received a grant of stock options to purchase 5,000 shares of Common Stock pursuant to the 2000 Plan at an exercise price equal to $15, the initial public offering price of a share of Common Stock. Such options vest in four equal annual installments, beginning on the second anniversary of the date of each such grant. NRG Energy also granted stock options to each of the Non-Employee Directors in June 2001 for the purchase of 5,000 shares of Common Stock at an exercise price equal to the fair market value of the Common Stock on the date of such grant, pursuant to the 2000 Plan. Each of the Non-Employee Directors participates in NRG Energy's Independent Director Deferral Plan (the "Deferral Plan"). The Deferral Plan allows Non-Employee Directors to defer all or a portion of his or her annual fees, meeting fees and other fees paid in connection with service on the Board of Directors to a cash deferral account, a stock unit account or a combination of such accounts. The Deferral Plan provides for a 20% premium on fees deferred into a stock unit account. Fees deferred under the Deferral Plan are paid out in cash upon the retirement of the Non-Employee Director from service on the Company's Board of Directors or upon two payout commencement dates other than retirement, as determined by the Non-Employee Director. Payout of fees deferred under the Deferral Plan are made in installments, with a minimum of two and maximum of ten such installments, or in a lump sum. Each of NRG Energy's directors has an indemnification agreement that entitles him or her to indemnification for claims asserted against them in their capacity as directors to the fullest extent NRG Energy's permitted by Delaware law. 99

TOTAL STOCKHOLDER RETURN COMPARISON The graph below compares the NRG Energy's cumulative total stockholder return on Common Stock with the cumulative total return of the Standard & Poor's 500 Composite Stock Price Index and an index of comparable peer issuers (the "Peer Group Index") from May 31, 2000, the first date on which the Common Stock began trading on the New York Stock Exchange, to December 31, 2001, NRG Energy's fiscal year end (assuming a $100 investment in each vehicle on May 31, 2000 and the reinvestment of all dividends). The Peer Group Index consists of the following publicly traded companies in the global power generation industry: AES Corp., Calpine Corp., Dynegy, Inc. and Mirant Corp. The former Peer Group consisted of the following publicly traded companies in the global power generation industry: AES Corp., Calpine Corp., Dynegy, Inc., Orion Power Holdings, Inc. and Mirant Corp. The former Peer Group differs from the current Peer Group because Orion Power Holdings, Inc. is no longer publically traded. In accordance with the rules of the SEC, the returns are indexed to a value of $100 at May 31, 2000, and the returns of each company in the Peer Group Index have been weighted according to their market capitalization at December 31, 2000.

PENSION PLAN TABLES NRG Energy participates in Xcel Energy's noncontributory, defined benefit pension plan. Such plan covers substantially all of NRG Energy's employees. As of January 1, 1999, the pension benefit formula that applies to the Named Executive Officers was changed and each Named Executive Officer, together with all other affected nonbargaining employees, was given an opportunity to choose between two retirement programs, the traditional program and the pension equity program. Messrs. Peterson, Bluhm and Noer have selected the traditional program and Messrs. Mataczynski and Bender have selected the pension equity program. Under the traditional program applicable to certain of the Named Executive Officers, the pension benefit is computed by taking the highest average compensation below the integration level times 1.1333% plus the highest average compensation above the integration level times 1.6333%. The result is multiplied by credited service. The integration level is one-third of the social security wage base. The annual compensation used to calculate average compensation is base salary for the year. After an employee has reached 30 years of service, no additional years of service are used in determining the pension benefit under the traditional program. The benefit amounts under the traditional program are computed in the form of a straight-life annuity. Under the pension equity program applicable to certain of the Named Executive Officers, the formula for determining the pension benefit is average compensation times credited years of service times 10%. The annual compensation used to calculate average compensation is base salary for the year plus bonus compensation paid in that same year. There is no maximum on the number of years of service used to determine the pension benefit. The benefit amounts under the pension equity program are computed in the form of a lump sum. Both programs feature a retirement spending account, which credits $1,400 plus interest annually. The opening balance as of January 1, 1999 was $1,400, multiplied by years of service. The employment agreement between Mr. Peterson and NRG Energy provides that Mr. Peterson will receive the accumulated value of his pension payments had he begun payments at his earliest retirement eligibility. Additionally, the employment agreement provides that, in the event that Mr. Peterson elects a lump sum payment, the value of his benefits will be calculated based on both his and his spouse's mortality, subject to certain financial performance measures.

EMPLOYMENT AGREEMENTS DAVID H. PETERSON EMPLOYMENT AGREEMENT NRG Energy has entered into an employment agreement with Mr. Peterson which provides that Mr. Peterson will be employed as NRG Energy's highest level executive officer. The term of the agreement expires June 27, 2004. During the term of the agreement, Mr. Peterson's base salary will be reviewed at least annually by the Compensation Committee of the Board of Directors for possible increase. The agreement provides that Mr. Peterson will receive retirement and welfare benefits no less favorable than those provided to any other officer of NRG Energy. In addition, the agreement provides for participation in a supplemental executive retirement plan such that the aggregate value of the retirement benefits that Mr. Peterson and his spouse will receive at the end of the term of the agreement under all of NRG Energy's defined benefit pension plans and those of NRG Energy's affiliates will not be less than the aggregate value of the benefits he would 106

have received had he continued, through the end of the term of the agreement, to participate in the NSP Deferred Compensation Plan, the NSP Excess Benefit Plan and the NSP Pension Plan. Such retirement benefits include amounts to compensate Mr. Peterson for the monthly defined benefit payments he would have received during the term of the agreement and prior to the date of his termination of employment if monthly benefit payments had commenced following the month in which he first became eligible for early retirement under the Xcel Energy Pension Plan. The agreement also provides for certain additional benefits to be paid upon Mr. Peterson's death. If Mr. Peterson's employment is terminated by NRG Energy without cause, or by Mr. Peterson with good reason, in each case as defined in the agreement, Mr. Peterson will continue to receive his salary, bonus at the greater of target bonus or actual bonus for the last plan year prior to termination, incentive compensation with cash replacing equity based awards and benefits under the agreement as if he had remained employed until the end of the term of the agreement and then retired, at which time he will be treated as eligible for retiree welfare benefits and other benefits provided to the retired senior executives. However, if the termination of employment is a result of a change of control, as defined in the Equity Plan, the compensation and benefits will be continued for the longer of 30 months or through the end of the employment period. In accordance with the terms of the agreement, Mr. Peterson has agreed not to compete with the business of NRG Energy during the period of his employment and for one year after his termination or resignation. Mr. Peterson has also agreed not to solicit any of NRG Energy's customers for any business purpose that competes with NRG Energy's business during the period of his employment or two years after his termination or resignation. Finally, during the period of his employment and for two years after his termination or resignation, Mr. Peterson has agreed not to disclose any of NRG Energy's confidential information to any person not authorized by NRG Energy to receive such confidential information. JAMES J. BENDER, LEONARD A. BLUHM, CRAIG A. MATACZYNSKI AND JOHN A. NOER SEVERANCE AGREEMENTS Messrs. Bender, Bluhm, Mataczynski and Noer are participants in the Company's Executive officer and Key Personnel Severance Plan (the "Plan"). In June and July 2001, the Company executed severance plan agreements with Messrs. Bender, Bluhm, Mataczynski and Noer pursuant to the Plan. Each such agreement remains in effect until the third anniversary of its effective date. Each agreement has an effective date of May 31, 2001, except for the Company's agreement with Mr. Noer, which has an effective date of January 15, 2001. The severance agreements provide that if the employment of Messrs. Bender, Bluhm, Mataczynski, or Noer is terminated due to his death or disability, he will receive his base salary and accrued vacation through the date of termination or resignation. Each such agreement further provides that if any of Messrs. Bender, Bluhm, Mataczynski or Noer is terminated for cause, or if any of them voluntarily resigns without good cause, he will receive his base salary and accrued vacation through the date of termination or resignation, plus all other amounts to which he is entitled under any compensation plans of the Company, at the time such payments are due. Each such agreement further provides for the payment of severance benefits in the event that any of Messrs. Bender, Bluhm, Mataczynski or Noer is terminated by the Company without cause, or if any of them terminates his employment within three months of a material change or reduction in his job responsibilities with the Company or as a result of a material breach by the Company of the compensation or benefit terms of the severance agreement. The severance benefits payable include the payment of two times the participant's base salary, plus two times the participant's average annual bonus earned over the two full years prior to the date of termination, or two times the participant's target annual bonus established for the bonus plan year in which the participant's termination occurs, whichever is greater. Severance benefits are also payable to each of Messrs. Bender, Bluhm, Mataczynski and Noer if, within six months prior to, or twelve months after, the effective date of a Change in Control (as defined in the Company's Severance Plan) of the Company, his employment with the Company ends as a result of either an involuntary termination of his employment by the Company for reasons other than cause, or by voluntary termination by him for cause. Whether or not a particular transaction constitutes a change of control is to be determined by the Board of Directors of the Company. In the event of a Change in Control of the Company, 107

the severance benefits payable include the payment of three times the participant's base salary, plus three times the participant's average annual bonus earned over the two full years prior to the date of termination, or three times the participant's target annual bonus established for the bonus plan year in which the participant's termination occurs, whichever is greater. Under the terms of each such agreement, each of Messrs. Bender, Bluhm, Mataczynski and Noer has agreed not to compete with the Company's business during the course of his employment and for one year after his resignation or termination, unless there has been a Change of Control of the Company. Additionally, Messrs. Bender, Bluhm, Mataczynski and Noer have agreed not to disclose any of the Company's confidential and proprietary information.

ITEM 13 -- CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS RELATIONSHIPS AND RELATED TRANSACTIONS NRG Energy was initially incorporated in Minnesota in 1989, and was reincorporated in Delaware in 1992, as a wholly owned subsidiary of NSP. The Company became publicly traded on May 31, 2000. In August 2000, NSP merged with NCE to form Xcel Energy. Following the completion in March 2001 of a public offering by NRG Energy of 18.4 million shares of Common Stock (the "March 2001 Offering"), Xcel Energy owns an approximate 74% interest in the Common Stock and Class A Common Stock of NRG Energy on a combined basis, representing 96.7% of the total voting power of the Common Stock and Class A Common Stock on a combined basis. In addition, 4 directors of NRG Energy are executive officers of Xcel Energy. NRG Energy and Xcel Energy have entered into material transactions and agreements with one another and are expected to enter into material transactions and agreements from time to time in the future. Material agreements and transactions currently existing or currently proposed between NRG Energy and Xcel Energy are described below. OPERATING AGREEMENTS NRG Energy has two agreements with Xcel Energy for the purchase of thermal energy. Under the terms of the agreements, Xcel Energy charges NRG Energy for certain costs (fuel, labor, plant maintenance and auxiliary power) incurred by Xcel Energy to produce thermal energy. NRG Energy paid $7.1 million in 2001 under these agreements. One of the agreements expires on December 31, 2002, and the other expires on December 31, 2006. NRG Energy and Xcel Energy have executed a new agreement, expiring on December 31, 2010, to replace the agreement that would have expired on December 31, 2002; this new agreement will not become effective until it is approved by the Minnesota Public Utilities Commission. NRG Energy has a renewable 10-year agreement with Xcel Energy, expiring on December 31, 2006, under which Xcel Energy agrees to purchase refuse-derived fuel for use in certain of its boilers, and NRG Energy agrees to pay Xcel Energy a burn incentive. Under this agreement, NRG Energy received from Xcel Energy $1.6 million in 2001, and NRG Energy paid to Xcel Energy $2.8 million in 2001. NRG Energy has entered into an operation and maintenance agreement with Xcel Energy with respect to its Elk River and Becker Facilities, under which NRG Energy receives a base management fee and is 109

reimbursed for costs it incurs. The operation and maintenance agreement also provides for a management incentive fee payable to NRG, based upon the financial performance of the facilities. NRG Energy earned a total management fee, in addition to reimbursed expenses, of $1.9 million in 2001. This agreement expires on December 31, 2003. NRG Energy and Xcel Energy have entered into an asset purchase agreement for the sale of Xcel Energy's Elk River and Becker Facilities to NRG Energy. The boards of directors of Xcel Energy and NRG have approved the transaction. The Minnesota Public Utilities Commission has approved Xcel Energy's request for the transfer of assets. Xcel Energy expects that the transaction will be completed by the second quarter of 2002. REIMBURSEMENT FOR ADMINISTRATIVE SERVICES NRG Energy reimburses Xcel Energy for certain overhead and administrative costs, including benefits administration, engineering support, accounting, and other shared services. Employees of NRG Energy participate in certain employee benefit plans of Xcel Energy. NRG Energy paid Xcel Energy $12.2 million in 2001 as reimbursement for certain overhead costs and the cost of services provided. TREECYCLE AGREEMENT In February 2001, a wholly-owned subsidiary of NRG Energy, NRG Processing Solutions LLC (NRG PS), entered into agreements with Xcel Energy to provide for the assignment by Xcel Energy to NRG PS of various leases and contracts with respect to Xcel Energy's Treecycle business unit. The Treecycle operation manages wood waste from Xcel Energy's line-clearance operations in the Minneapolis and St. Paul metropolitan area. In conjunction with this transfer, NRG Energy and Xcel Energy have also entered into a one-year processing agreement whereby NRG PS agreed to process Xcel Energy's wood waste until December 31, 2001, for a minimum fee of $500,000. Such agreements were approved by the Minnesota Public Utilities Commission in April 2001. The agreements were not renewed. During the year ended December 31, 2001, NRG Energy received the minimum fee of $500,000 from Xcel Energy. CONSULTING SERVICES AGREEMENT NRG Energy has an agreement with Utility Engineering Corporation, a wholly owned subsidiary of Xcel Energy, under which Utility Engineering provides consulting services to NRG Energy. Consulting services are provided from time to time at NRG Energy's request. NRG Energy paid $1.4 million to Utility Engineering for consulting services in 2001. TAX ALLOCATION AGREEMENT NRG Energy was formerly a member of Xcel Energy's consolidated tax group for United States federal income tax purposes. Following the completion of the March 2001 Offering, Xcel Energy owns equity securities representing less than 80% of NRG Energy's value and, accordingly, NRG Energy is no longer a member of Xcel Energy's consolidated tax group. The responsibility for payment of taxes and the allocation between Xcel Energy and NRG Energy of tax benefits and liabilities was previously governed by a tax sharing agreement between NRG Energy and Xcel Energy. Such tax sharing agreement was replaced by a tax allocation agreement, which became effective as of December 2000, that formalizes the various practices which arose under the previous tax sharing agreement and reflects the change in NRG Energy's status from a wholly-owned subsidiary of Xcel Energy to a majority-owned subsidiary. OPTION AGREEMENT NRG Energy has entered into an option agreement with Xcel Energy under which NRG Energy has granted to Xcel Energy and its affiliates a continuing option to purchase additional shares of Common Stock. In the event that NRG Energy issues equity securities, Xcel Energy and its affiliates may exercise options to purchase shares of Common Stock to the extent necessary to maintain or restore an ownership percentage of 80% of the outstanding shares of Common Stock and Class A Common Stock on a combined basis. Such 110

option agreement expires if and when Xcel Energy and its affiliates beneficially own less than 30% of the outstanding Common Stock and Class A Common Stock on a combined basis. Following the March 2001 Offering, Xcel Energy's ownership in NRG Energy was reduced to approximately 74% of the outstanding shares of Common Stock and Class A Common Stock on a combined basis. Xcel Energy waived its rights under such option agreement in connection with the March 2001 offering. This option agreement would terminate upon completion of Xcel Energy's exchange offer for NRG Energy common stock. REGISTRATION RIGHTS AGREEMENT NRG Energy has entered into a registration rights agreement with Xcel Energy, under which NRG Energy has agreed to register the shares of Common Stock issuable upon conversion of shares of Class A Common Stock held by Xcel Energy and its affiliates under the following circumstances: - Demand Rights. Upon the written request of Xcel Energy, NRG Energy will register shares of Common Stock held by Xcel Energy and its affiliates specified in its request for resale under an appropriate registration statement filed and declared effective by the SEC. Xcel Energy may make a demand so long as: - it requests registration of shares with an anticipated aggregate offering price of at least $20 million; - it has made no more than four previous requests for the registration of common stock; and - NRG Energy has not completed a registered offering of Common Stock within the 180 day period before Xcel Energy's request. - Piggyback Rights. If at any time NRG Energy registers newly issued shares of Common Stock or registers outstanding shares of Common Stock for resale on behalf of any holder of Common Stock, Xcel Energy and its affiliates may elect to include in such registration any shares of Common Stock it holds. If the offering is an underwritten offering, the managing underwriter may exclude up to 75% of the shares of Xcel Energy and its affiliates if market factors dictate, but only if Xcel Energy and its affiliates is not exercising a demand right, described above, and only if all other shares being sold by other stockholders are excluded first. - Termination. The registration rights agreement will terminate upon the earlier of seven years from the date of the agreement or the date on which all remaining shares of Common Stock held by Xcel Energy and its affiliates, or issuable to Xcel Energy and its affiliates upon conversion of Class A Common Stock, may be sold in any 90-day period in compliance with Rule 144 under the Securities Act. This registration rights agreement will terminate upon the completion of Xcel Energy's tender offer for the exchange of NRG Energy's common stock. 111

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 Administrative Agent may rely on any such telephonic or facsimile 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 Administrative 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 Administrative Agent shall give prompt telephonic or facsimile notice to each Bank of any notice from the Borrower received pursuant to Section 2.5(a) above. The Administrative 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 Administrative 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 Administrative 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 Administrative Agent within the period required by Section 2.8(a) that it 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 15

available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent in Chicago, Illinois. The Administrative Agent shall make available to the Borrower Loans at the Administrative Agent's principal office in Chicago, Illinois or such other office as the Administrative Agent has previously agreed to, in writing, with the Borrower. (e) Administrative Agent Reliance on Bank Funding. Unless the Administrative Agent shall have been notified by a Bank before the date on which such Bank is scheduled to make payment to the Administrative 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 Administrative Agent may assume that such Bank has made such payment when due and the Administrative 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 Administrative Agent, such Bank shall, on demand, pay to the Administrative 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 Administrative Agent at a rate per annum equal to the Federal Funds Rate. If such amount is not received from such Bank by the Administrative Agent immediately upon demand, the Borrower will, on demand, repay to the Administrative 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; (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 16

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 Administrative Agent or, in the case of a Borrowing of Base Rate Loans, notice delivered to the Administrative 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 Administrative 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 Administrative 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 Administrative 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. Section 2.9 Default Rate. At any time (i) an Event of Default has occurred and is continuing, or (ii) after the occurrence of any event or circumstance which has a Material 17

Adverse Effect, each 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 Event of Default arises or such event or circumstance having a Material Adverse Effect occurs, as applicable, 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: 18

(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 Administrative 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 Administrative 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 Administrative 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 ABN AMRO Bank N.V. and/or Salomon Smith Barney Inc. the fees set forth in the Fee Letters at the times specified in the Fee Letters 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 Administrative 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 19

Commitments (whether 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) 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 Administrative 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 Administrative Agent by no later than 12:00 Noon (Chicago time) on the due date thereof at the principal office of the Administrative Agent in New York, New York pursuant to the payment instructions set forth on Part A of Schedule 4 hereof (or such other location in the United States as the Administrative Agent may designate to the Borrower). Any payments received after such time shall be deemed to have been received by the Administrative 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 Administrative 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 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 20

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.

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.

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 7.15, no authorization, consent, license, exemption, filing or registration with any court or governmental department, agency or instrumentality (including under the Public Utility Holding Company Act of 1935, as amended), nor any approval or consent of the stockholders of the Borrower or any Subsidiary or from any other Person, is necessary for 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 5.11 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 22

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.

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. (c) Notwithstanding anything in this Agreement to the contrary, the Borrower may not sell its equity interest in any Material Subsidiary unless prior to such sale the Borrower has delivered to the Administrative Agent a certificate pursuant to which the Borrower certifies that both immediately prior, and immediately after giving effect, to such sale no Default or Event of Default has occurred and is continuing and no event or circumstance has occurred which has had, or which is reasonably expected to have, a Material Adverse Effect.

For purposes of this covenant, (i) 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, and (ii) the amount of Indebtedness which may be excluded per the immediately preceding clause (i) shall not exceed $1,000,000,000.

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 Administrative Agent shall, if so directed by the Required Banks by written notice to the Borrower: (a) 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) 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 Administrative 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 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, continue to maintain or convert a Borrowing into 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, maintain or convert a Borrowing into Eurocurrency Loans under this 34

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 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 Administrative 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 Administrative Agent that the Federal Funds Rate or LIBOR, as applicable, as reasonably determined by the Administrative 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 Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative 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 35

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 (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 Administrative 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 Administrative 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 36

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 Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. (c) Each Bank that determines to seek compensation under this Section 9.3 shall notify the Borrower and the Administrative 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 Administrative Agent, to seek a substitute Bank or Banks reasonably satisfactory to the Administrative 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 Administrative 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. 37

SECTION 10. THE ADMINISTRATIVE AGENT. Section 10.1 Appointment and Authorization of Administrative Agent. Each Bank hereby appoints ABN AMRO Bank N.V. as the Administrative Agent under the Credit Documents and hereby authorizes the agent to take such action as Administrative Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Credit Documents. The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative 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 Administrative Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein. Section 10.2 Administrative Agent and its Affiliates. The Administrative 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 Administrative Agent, and the Administrative 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 Administrative 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 Administrative Agent in its individual capacity as a Bank. References in Section 2 hereof to the Administrative Agent's Loans, or to the amount owing to the Administrative Agent for which an interest rate is being determined, refer to the Administrative Agent in its individual capacity as a Bank. Section 10.3 Action by Administrative Agent. If the Administrative Agent receives from the Borrower a written notice of an Event of Default pursuant to Section 7.6(c)(i) hereof, the Administrative Agent shall promptly give each of the Banks written notice thereof. The obligations of the Administrative Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Administrative 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 Administrative Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Administrative 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 Administrative 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 Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in using its discretion in failing to take or in taking any action hereunder and thereunder. 38

Section 10.4 Consultation with Experts. The Administrative 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 Administrative Agent; Credit Decision. Neither the Administrative 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 Administrative 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 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 Administrative 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 Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. The Administrative 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 Administrative 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 Administrative 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 Administrative Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with the Administrative Agent signed by such payee in form satisfactory to the Administrative Agent. Each Bank acknowledges that it has independently and without reliance on the Administrative 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 Administrative 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 Administrative 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 39

be indemnified. The obligations of the Banks under this Section 10.6 shall survive termination of this Agreement. Section 10.7 Resignation of Administrative Agent and Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and the Borrower. Upon any such resignation of the Administrative Agent, the Required Banks shall have the right to appoint a successor Administrative 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 Administrative Agent shall have been so appointed by the Required Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Administrative Agent's giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, with the consent of the Borrower, appoint a successor Administrative 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 Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring or removed Administrative Agent under the Credit Documents, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder. After any retiring Administrative Agent's resignation hereunder as Administrative 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 Administrative 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 Administrative Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Bank or the Administrative Agent (as the case may be) would have received had such withholding not been made. If the Administrative Agent or any Bank pays any amount in respect of any such taxes, penalties or interest the Borrower shall reimburse the Administrative 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 Administrative Agent on whose account such withholding was made (with a copy to the Administrative Agent if not the recipient of the original) on or before the thirtieth day after payment. If any Bank or the Administrative Agent determines it has 40

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 Administrative 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 Administrative Agent determines is attributable to such deduction or withholding and which will leave such Bank or Administrative 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 Administrative Agent to arrange its tax affairs in whatever manner it thinks fit nor oblige any Bank or the Administrative 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 Administrative 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 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 Administrative 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 Administrative 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 Administrative 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 Administrative 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 Administrative 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 41

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 Administrative 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. 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 this Section 11.16 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations. If and to the extent any indemnification or reimbursement obligation of the Borrower under the Credit Documents is deemed unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of the underlying obligation permissible under applicable law. 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 42

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 facsimile or other electronic communication) and shall be given to a party hereunder at its address or facsimile number set forth below or such other address or facsimile number as such party may hereafter specify by notice to the Administrative Agent and the Borrower, given by courier, by United States certified or registered mail, or by other telecommunication device capable of creating a written record of such notice and its 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. This Agreement may also be executed by facsimile signature, and each such facsimile signature shall for all intents and purposes be deemed and original signature of the signatory thereof. 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 its rights and/or obligations 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 Administrative 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 44

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. 45

Section 11.12 Assignment of Commitments by Banks. (a) Each Bank shall have the right at any time, with the written consent of the Borrower and Administrative Agent (which consent shall not be unreasonably withheld or delayed), 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 (i) neither the consent of the Borrower nor of the Administrative Agent shall be required for any Bank to assign all or part of its Revolving Credit Commitment to any Affiliate of the assigning Bank or another Bank and (ii) the consent of the Borrower shall not be required if an Event of Default then exists. 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 Administrative Agent of an executed copy of such assignment agreement and the forms referred to in Section 11.1 hereof, if applicable, and the payment of a $3,500 recordation fee to the Administrative 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 or any portion of its Revolving Credit Commitment to an Affiliate of such Bank or at the request of the Borrower pursuant to Section 11.13(b), 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 without notice to, or the consent of, the Borrower or the Administrative Agent. (b) Notwithstanding anything to the contrary contained in this Agreement, any Bank (a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC") of such Granting Lender identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any such SPC to make any Loan, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 2.3 or 2.8 than the Granting Lender would have been entitled to receive had the Granting Lender not otherwise granted such SPC the option to provide 46

any Loan to the Borrower. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Bank would otherwise be liable so long as, and to the extent that, the related Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the Administrative Agent and each Bank against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be incurred by or asserted against the Borrower, the Administrative Agent or such Bank, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the rights of a Bank hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and that the voting rights attributable to any Loan made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement, any SPC may with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Loans to the Granting Lender. This Section may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loan is being funded by an SPC at the time of such amendment. Section 11.13 Amendments. (a) 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 Administrative Agent are affected thereby, the Administrative 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 47

(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. (b) 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") does not approve it, the Borrower may propose that another bank which is reasonably acceptable to the Administrative 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 Administrative 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 Administrative Agent be a Replaceable Bank. Section 11.14 Nonliability of Agents and Lenders. The relationship between the Borrower on the one hand and the Banks, the Administrative Agent and the Documentation Agents on the other hand shall be solely that of borrower and lender. Neither the Administrative Agent, the Syndication Agents, the Documentation Agents nor any Bank shall have any fiduciary duty to the Borrower. Neither the Administrative Agent, the Syndication Agents, the Documentation Agents nor any Bank undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower's business or operations. The Borrower agrees that neither the Administrative Agent, the Syndication Agents, the Documentation Agents nor any Bank shall have liability to the Borrower (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower in connection with, arising out of, or in any way related to the transactions contemplated and the relationship established by the Credit Documents, or any act,. omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. Neither the Administrative Agent, the Syndication Agents, the Documentation Agents, any Bank nor any of their respective Subsidiaries, Affiliates, officers or directors shall have any liability with respect to, and the Borrower hereby waives, releases and agrees not to sue for, any special, indirect, consequential or punitive damages in connection with, arising out of, or in any way related to any of the Credit Documents or the transactions contemplated thereby. Section 11.15 Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement. 48

Section 11.16 Legal Fees, Other Costs and Indemnification. The Borrower agrees to pay on demand all reasonable costs and expenses of the Administrative Agent and the Syndication Agents in connection with the preparation and negotiation of the Credit Documents (including past and future reasonable out-of-pocket expenses incurred by ABN AMRO Bank N.V. or Salomon Smith Barney Inc. in connection with the syndication of the transaction), including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent and the Syndication Agents, 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 Administrative 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 or that may be claimed against any of them by any Person arising out of or relating to any Credit Document (including any relating to any misrepresentation or false certification by or on behalf of the Borrower) 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 Administrative Agent or a Bank at any time, shall reimburse the Administrative Agent or Bank for any reasonable costs and legal or other expenses incurred in connection with investigating or defending against any of the foregoing or the enforcement of any rights or remedies under this Agreement, any Note and the other documents to be delivered hereunder, except if the same is directly due to the gross negligence or willful misconduct of the party to be indemnified. Section 11.17 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 11.18 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. Section 11.19 Governing Law. The validity and interpretation of this Agreement and the other Credit Documents, and the terms and conditions set forth herein, shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to any provisions relating to conflict of laws other than section 5-1401 of the New York General Obligations Law. Section 11.20 Submission to Jurisdiction; Waiver of Jury Trial. EACH OF THE BORROWER, EACH BANK AND THE ADMINISTRATIVE AGENT HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND OF ANY NEW 49

EACH OF THE BORROWER, EACH BANK AND THE ADMINISTRATIVE AGENT HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

EXHIBIT 99.1 WEST COAST POWER LLC Consolidated Financial Statements As of December 31, 2001 Together With Auditors' Report

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Member of West Coast Power LLC: We have audited the accompanying consolidated balance sheets of West Coast Power LLC (a Delaware limited liability company) as of December 31, 2001 and 2000, and the related consolidated statements of operations, member equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2001. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of West Coast Power LLC as of December 31, 2001 and 2000, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States. Our audit was made for the purpose of forming an opinion on the basic financial statements taken as a whole. The 2001 consolidating information in Note 10 is presented for purposes of additional analysis and is not a required part of the financial statements. This information has been subjected to the auditing procedures applied in our audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ Arthur Andersen LLP Houston, Texas February 28, 2002 (except with respect to the matter discussed in Note 9, as to which the date is March 11, 2002)

WEST COAST POWER LLC NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. BACKGROUND AND NATURE OF OPERATIONS: Background Prior to 1999, Dynegy Power Corp. (DPC), a wholly owned subsidiary of Dynegy Inc. (Dynegy), and NRG Energy, Inc. (NRG), a majority owned subsidiary of Northern States Power Company until its merger with New Century Energies, Inc., to form Xcel Energy, Inc., in August 2000 (collectively, the Sponsors) each held a 50 percent interest in two limited liability companies: El Segundo Power, LLC (ESP), and Long Beach Generation LLC (LBG) (collectively, the Historical LLCs). In May 1999, the Sponsors acquired the assets and liabilities which make up Cabrillo Power I LLC (Cabrillo I) and Cabrillo Power II LLC (Cabrillo II) (collectively, the New LLCs). Effective June 30, 1999, the Sponsors formed WCP Holdings LLC (Holdings) and West Coast Power LLC (WCP), a Delaware limited liability company. The Sponsors have an equal interest in Holdings and share in profits and losses equally. WCP is wholly owned by Holdings and serves as a holding company for the Historical LLCs and New LLCs. Upon formation of WCP, the assets and liabilities of the Historical LLCs were contributed to WCP by the Sponsors and were recorded at their historical costs because the transfer represented a reorganization of entities under common control. These financial statements include the results of operations of the Historical LLCs for all of 2001, 2000 and 1999 and the results of operations of the New LLCs since the date of their acquisition. Operations are governed by the executive committee with two representatives from each Sponsor. Nature of Operations ESP owns a 1,020-megawatt (MW) plant located in El Segundo, California, consisting of four steam electric generating units. ESP's assets were purchased from the Southern California Edison Company (SCE) through a competitive bid process for $88.3 million on April 4, 1998. Historically, the facility had operated as a merchant plant, selling energy and ancillary services through the deregulated California wholesale electric market. In 2001, the facility entered into a long-term power purchase agreement (PPA) with the California Department of Water Resources (CDWR), as discussed in Note 6, for a portion of the facility's generation through December 2004. The facility also maintained a must-run agreement (MRA) with the California Independent System Operator (ISO) that was terminated by the ISO on December 31, 1999. LBG owns a 560-MW plant located in Long Beach, California, consisting of seven 60-MW gas turbine generators and two 70-MW steam turbine units. LBG's assets were purchased from SCE on April 1, 1998, through a competitive bid process for $29.8 million. Historically, the facility had operated as a merchant plant, selling energy and ancillary services through the deregulated California wholesale electric market. In 2001, the facility entered into a long-term PPA with the CDWR, as discussed in Note 6, for a portion of the facility's generation through December 2004. Cabrillo I owns a 965-MW plant located in Carlsbad, California, consisting of five steam electric generating units and one combustion turbine. Cabrillo I's assets were purchased from San Diego Gas & Electric (SDG&E) on May 22, 1999, at a purchase price of $283.4 million. Historically, the facility had operated as a merchant plant, selling energy and ancillary services through the deregulated California wholesale electric market. In 2001, the facility entered into a long-term PPA with the CDWR, as discussed in Note 6, for a portion of the facility's generation through December 2004. The facility also maintains an MRA with the ISO.

Cabrillo II owns 17 combustion turbines with an aggregate capacity of 253 MW located throughout San Diego County, California. Cabrillo II's assets were purchased on May 22, 1999, from SDG&E through a competitive bid process for a purchase price of $69.1 million. The facility operates as a merchant plant, selling energy and ancillary services to the California wholesale electric market. The facility also maintains an MRA with the ISO. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Consolidation The consolidated financial statements include the accounts of WCP after elimination of intercompany accounts and transactions. Cash and Cash Equivalents WCP considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Inventories Inventories are stated at the lower of market or cost using last-in, first-out (LIFO) or average cost and are comprised of the following at December 31, 2001 and 2000: 2001 2000 -------------- -------------- Emissions credits (average cost) $ 7,292,677 $ 12,872,541 Materials and supplies (average cost) 10,810,138 10,372,169 Fuel oil (LIFO) 24,961,827 7,277,675 -------------- -------------- $ 43,064,642 $ 30,522,385 ============= ============= Emission credits represent costs paid by WCP to acquire additional NOx credits. WCP uses these credits to comply with emission caps imposed by various environmental laws under which it must operate. As individual credits are used, costs are recognized as operating expense. See additional discussion below at "Environmental Costs." Plant and Equipment Plant and equipment costs are being depreciated on a straight-line basis over estimated useful lives of 3 to 29 years. Impairment of Long-Lived Assets In the event that facts and circumstances indicate that the carrying amounts of long-lived assets could be impaired, an evaluation of recoverability is performed that compares the estimated future undiscounted cash flows associated with the asset to the asset's carrying amount to determine if a write-down is required. If this evaluation indicates that the assets will not be recoverable, the carrying value of WCP's assets would be reduced to their estimated fair value. Goodwill Goodwill represents the excess purchase cost over the estimated fair value of the assets acquired and liabilities assumed and has been amortized on a straight-line basis over 3 to 27 year estimated useful lives based on the useful life of the related plant and equipment.

Overhaul and Maintenance Reserves Effective January 1, 2001, WCP changed its method of accounting for major maintenance costs. Prior to 2001, WCP accrued major overhaul and maintenance costs expected to be incurred that are not covered by the operations and maintenance (O&M) agreements. Other maintenance and repair costs were charged to expense as incurred. As of January 1, 2001, WCP capitalizes major overhaul and maintenance costs over $100,000 that have future benefits and that are not covered by the O&M agreements as these costs are incurred. These costs are depreciated individually over the expected life of each overhaul or addition. Removal costs, parts having an expected life of one year or less and normal, routine maintenance and repair costs are expensed as incurred. The change had no material effect on the consolidated financial statements. Federal Income Taxes WCP is not a taxable entity for federal income tax purposes. Accordingly, there is no provision for income taxes in the accompanying consolidated financial statements. Revenue Recognition Revenues from the sale of energy and ancillary services are recorded based upon output delivered and/or service priced at market or other terms as contractually stipulated. Revenues received from the MRA are primarily derived from availability payments and amounts based on reimbursing variable costs. Historically, WCP's sales have been to the ISO, the California Power Exchange (PX) and Dynegy Power Marketing, Inc. (DYPM). In March 2001, WCP entered into a long-term PPA with the CDWR, as discussed at Note 6. Revenues identified as being subject to future resolution are accounted for as discussed in Note 8. Environmental Costs Environmental costs relating to current operations are expensed. Liabilities are recorded when an environmental assessment indicates that remedial efforts are probable and the costs can be reasonably estimated. During 2001, the state of California disallowed the purchase of NOx emission credits, but has allowed generators to use credits previously purchased. LBG and ESP have the ability to share emissions credits. When generators' emissions exceed the yearly allowance of credits and the inventory of previously purchased credits, a fine of $7.50 per pound of excess emissions is assessed to that generator and future credit allocations are reduced. No such fines were incurred by WCP in 2001. Cabrillo I executed a variance mitigation agreement (VMA) with the San Diego County Air Pollution Control District (SDC APCD) in March 2001 as Cabrillo I would not be able to meet District Rule 69's more stringent NOx emissions standards in 2001. The SDC APCD board gave Cabrillo I until July 1, 2003, to meet emission standards and approved the VMA for that time period, which set the mitigation fee for excess emissions above 419 tons per year at $15,500 per ton. WCP incurred approximately $11.1 million in mitigation fees during 2001. All emissions expenses are included in operating costs. Risk Management Activities WCP enters into various derivative instruments to hedge the risks associated with changes in commodity prices and interest rates. WCP uses physical forward contracts to hedge a portion of its exposure to price fluctuations of natural gas and electricity. Effective January 1, 2001, hedging gains and losses are recognized in accordance with Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities." Prior to the adoption of SFAS No. 133, WCP recognized hedging gains and losses when the related sales transactions occurred. WCP also entered into interest rate swap agreements, which effectively exchange variable interest rate debt for fixed interest rate debt. The agreements are used to reduce the exposure to possible increases in interest rates. WCP entered into these swap agreements with major financial institutions.

Concentration of Credit Risk WCP sells its electricity production to purchasers of electricity in California, which included the PX (prior to its declaring bankruptcy in January 2001), the ISO and, beginning in 2001, the CDWR. WCP remains exposed to credit risk on its outstanding ISO and PX receivables for power delivered from November 2000 through January 2001. Management is continually assessing WCP's exposure related to its California receivables and establishes reserves to reflect market uncertainties, as discussed in Notes 8 and 9. Use of Estimates in Financial Statement Preparation The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires estimates and assumptions that affect the reported amounts of assets and liabilities as well as certain disclosures. WCP's financial statements include amounts that are based on management's best estimates and judgments. Such estimates include, among other things, estimated reserves for probable contingencies such as those discussed in Note 8. Actual results could differ from those estimates. Fair Value of Financial Instruments WCP's financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable and debt instruments. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to the short-term maturity of these instruments. The fair value of WCP's debt instruments is considered to approximate the carrying amount of these instruments as their interest rates are based on the London Interbank Offering Rate (LIBOR). Additionally, WCP has entered into certain interest rate swap agreements in order to fix its effective interest rate as discussed in Note 7, fair value hedges, and electricity and gas options as discussed in Note 3. Adoption of SFAS No. 133 The Financial Accounting Standards Board (FASB) issued and subsequently amended SFAS No. 133, which became effective January 1, 2001. Provisions in SFAS No. 133, as amended, affect the accounting and disclosure of certain contractual arrangements and operations of WCP. Under SFAS No. 133, as amended, all derivative instruments are recognized in the balance sheet at their fair values and changes in fair value are recognized immediately in earnings, unless the derivatives qualify and are designated as hedges of future cash flows or qualify and are designated as normal purchases and sales. For derivatives treated as hedges of future cash flows, the effective portion of changes in the fair value of the derivative instrument is recorded in other comprehensive income until the related hedged items impact earnings. Any ineffective portion of a hedge is reported in earnings immediately. For derivatives treated as fair value hedges, changes in the fair value of the derivative and changes in the fair value of the hedged risk attributable to the related asset, liability or firm commitment are recorded in current period earnings. If the fair value hedge is effective, the amounts recorded to income attributable to the derivative and hedged risk will offset. Derivatives treated as normal purchases or sales are recorded and recognized in income using accrual accounting. WCP adopted SFAS No. 133 on January 1, 2001, and recorded a cumulative effect adjustment of approximately $(0.1) million to other comprehensive income attributable to certain gas and interest rate cash flow hedges. There was no impact on earnings at adoption. New Accounting Pronouncements In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 144 addresses the accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," and Accounting Principles Board (APB) Opinion No. 30, "Reporting the Results of Operations - Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events, and Transactions." WCP's adoption of SFAS No. 144 on January 1, 2002, did not have any impact on WCP's consolidated financial position or results of operations.

During 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets," which discontinues goodwill amortization over its estimated useful life; rather, goodwill will be subject to at least an annual fair value based impairment test. WCP is currently analyzing any impact the adoption of SFAS No. 142 effective January 1, 2002, will have on the consolidated financial position and results of operations for WCP. In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred with the associated asset retirement costs being capitalized as a part of the carrying amount of the long-lived asset. SFAS No. 143 also includes disclosure requirements that provide a description of asset retirement obligations and reconciliation of changes in the components of those obligations. WCP is evaluating the future financial effects of adopting SFAS No. 143 and expects to adopt the standard effective January 1, 2003. Reclassifications Certain reclassifications have been made to conform the prior year presentation to the current year presentation. 3. DERIVATIVES AND HEDGING: In 2000, WCP had purchased and sold gas and electricity options to manage the operating margins of its plants during 2001. The purchased gas call options had a fair value of approximately $1.4 million, and the sold electricity call options had a fair value of approximately $(12.2) million at December 31, 2000. The purchased gas calls were designated as cash flow hedges and, accordingly, changes in the market value of these contracts and the premiums paid were deferred until the actual natural gas purchases occurred in accordance with accounting principles generally accepted in the United States prior to the adoption of SFAS No. 133. The sold electricity options did not qualify for hedge accounting, and changes in the market value of these contracts were recorded in income. For the year ended December 31, 2000, WCP had recorded expense of approximately $12.2 million related to the sold electricity options. During 2001, these options were exercised. As electricity prices decreased significantly, WCP recognized income of approximately $12.1 million related to the sold electricity options. As a result of interpretations of SFAS No. 133 in 2001, WCP determined that the CDWR contract qualifies for the normal purchases and sales exception. WCP has entered into other forward purchase sales agreements for physical delivery of gas and other forward sales agreements for physical delivery of power that qualify for the normal purchases and normal sales exception to SFAS No. 133. WCP enters into interest rate swaps which qualify as cash flow hedges. These interest rate swaps are used to convert the floating interest rate component of debt to fixed rates as discussed in Note 7. During the year ended December 31, 2001, there was no material ineffectiveness from changes in fair value of hedge positions, and no amounts were excluded from the assessment of hedge effectiveness related to the hedge of future cash flows. Additionally, no amounts were reclassified to earnings in connection with forecasted transactions that were no longer considered probable. The balance in other comprehensive income at December 31, 2001, is expected to be reclassified to future earnings contemporaneously with the payments of interest. Of this amount, approximately $3.3 million of expense is estimated to be reclassified into earnings over the year ending December 31, 2002. The actual amounts that will be reclassified to earnings over the next year and beyond could vary materially from these estimates as a result of changes in market conditions. WCP has entered into a series of fixed price electricity purchases to hedge the fair value of its fixed price CDWR PPA. During the year ended December 31, 2001, there was no ineffectiveness from changes in fair value of hedge positions and no amounts were excluded from the assessment of hedge effectiveness. Additionally, no amounts were recognized in relation to firm commitments that no longer qualified as fair value hedge items.

The value of the fair value hedge at December 31, 2001, is approximately $(188.4) million and is included in the derivative liability accounts. The corresponding value of the hedged risk is approximately $188.4 million and is included in the derivative asset accounts. 4. RELATED PARTIES: WCP purchases fuel for its plants under natural gas supply agreements (GSAs) with Dynegy Marketing and Trade (DMT), an affiliate of WCP. Charges for fuel are based upon similar terms and conditions as could be obtained from third parties. WCP contracted with DYPM, an affiliate of WCP, to provide all power scheduling, power marketing and risk management for WCP under an energy management agreement (the EMA). Additionally, WCP contracted with DMT to provide all scheduling and marketing of fuel supply for WCP under the EMA. WCP contracted with NRG West, Inc., an affiliate of WCP, to manage the operations and management services agreements (OMSA). The services provided under the OMSA consisted primarily of overseeing the operations and maintenance efforts of SCE and SDG&E. SCE operated ESP and LBG until April 2000, and SDG&E operated Cabrillo I and Cabrillo II until May 2001. WCP then entered into O&M agreements with NRG Cabrillo Power Operations Inc. and NRG El Segundo Operations Inc., affiliates of WCP, for Cabrillo I and Cabrillo II effective May 2001 and for ESP and LBG effective April 2000. Fees for services primarily include recovery of the costs of operating the plant as approved in the annual budget and a base monthly fee. When the OMSAs were terminated once NRG became operator, WCP contracted with NRG Development Company, Inc., an affiliate of WCP, to provide services under the Administrative Management Agreement (the AMA). Services provided under the AMA include local services not covered under the O&M agreements, including environmental, engineering, legal and public relations services. Fees for such services are subject to executive committee approval if the amounts exceed a certain percentage of the applicable approved budget. WCP entered into an administrative services management agreement (the ASMA) with Dynegy Power Management Services, L.P., an affiliate of WCP, which provides administrative services such as business management and accounting to WCP. Fees for such services are subject to executive committee approval if the amounts exceed a certain percentage of the applicable annual approved budget. In addition to the related-party transactions listed above, WCP paid $14.2 million interest to DMT, as discussed in Note 8. Affiliates of WCP provide various services for WCP. Charges for these services are included in WCP's operating and general and administrative expenses and consisted of the following for 2001, 2000 and 1999: 2001 2000 1999 -------------- -------------- -------------- Operating expenses- Fuel $1,054,268,850 $ 482,937,131 $ 147,503,316 EMA charges 17,016,988 9,091,528 3,869,387 OMSA, O&M and AMA charges 51,935,752 15,373,707 744,401 -------------- -------------- -------------- $1,123,221,590 $ 507,402,366 $ 152,117,104 ============== ============== ============== ASMA fees included in general and administrative expenses $ 1,374,214 $ 776,403 $ 491,659 ============== ============== ==============

5. OPERATION AND MAINTENANCE AGREEMENTS: For the New LLCs' acquisition, WCP was required to enter into an O&M agreement with SDG&E which expired in May 2001. For 1999, the Historical LLCs were operated under an O&M agreement with SCE which expired in early 2000. The SDG&E and SCE O&M agreements were cost-plus agreements based on SDG&E's and SCE's estimates of the direct and indirect service costs for operating and maintaining the plant sites. Expenses related to such services of approximately $5.5 million, $14.1 million and $25.9 million were included in nonaffiliate operating costs in the accompanying consolidated statements of operations for 2001, 2000 and 1999, respectively. 6. POWER PURCHASE AGREEMENT: WCP entered into a long-term PPA with the CDWR in March 2001. From inception through December 31, 2001, the CDWR contracted for fixed price capacity sales of an aggregate of 1,000 MW from WCP's facilities. From January 2002 through December 31, 2004, the CDWR contracted for fixed price firm energy and fixed price capacity representing a substantial portion of WCP's capacity. Sales to CDWR constituted greater than 10 percent of WCP's total revenues in 2001. 7. LONG-TERM DEBT: WCP entered into a credit agreement with Bank of America Securities LLC, as agent, to arrange with a syndicate of banks (the Lenders) a five-year, $322.5 million amortizing term loan with a balloon payment and a $40 million working capital facility line of credit (the Credit Agreement). The Credit Agreement matures in June 2004. At December 31, 2001, no amounts were outstanding under the working capital facility. The interest rate on the outstanding loan balance was LIBOR plus 2.0 percent, which increased on July 1, 2001, to 2.125 percent. On September 30, 1999, WCP entered into two interest rate swap agreements related to the credit facility. One agreement effectively fixed the interest rate at 6.435 percent for the first $60 million and matures June 2004. The second swap agreement effectively fixed the interest rate at 6.230 percent for an incremental $40 million and matures in June 2002. At December 31, 2001, the fair values of the swaps maturing in 2004 and 2002, were approximately $(3.7) million and $(0.8) million, respectively. These swaps are designated as hedges of the future cash outflows for interest payments on the debt. WCP paid interest on the term loan, working capital line of credit and interest rate swaps totaling approximately $18.6 million in 2001, $27.3 million in 2000 and $13.2 million in 1999. The Credit Agreement is secured by all of WCP's assets and membership interests. The Sponsors have provided limited guarantees for environmental capital expenditures and interest. Environmental capital expenditures, as defined in the Credit Agreement, will be funded by the Sponsors, who will make capital contributions or subordinated loans to WCP to the extent necessary for environmental capital expenditures up to an aggregate of $60 million as of December 31, 2001. The Sponsors have each provided guarantees of approximately $25 million associated with minimum insurance requirements under the Credit Agreement. Additionally, in December 2001, one credit agency's downgrade of Dynegy's debt triggered a requirement for additional credit assurance. As such, Dynegy was required by the Lenders to post a $4.5 million letter of credit for WCP, which expires December 31, 2002. After year-end, this letter of credit was reduced to approximately $3.3 million following WCP's annual payment on the term loan. Future principal maturities under the term loan are as follows: 2002 $ 18,000,000 2003 18,000,000 2004 114,056,703 ---------------- $ 150,056,703 ===============

8. COMMITMENTS AND CONTINGENCIES: California Power and Natural Gas Markets Beginning in the fourth quarter of 2000, the power and natural gas markets in California experienced substantial volatility driven principally by a fundamental imbalance in supply and demand and the retail electricity price caps imposed on the state's two largest utilities. Both Pacific Gas & Electric Company (PG&E) and SCE defaulted on payments to the ISO and the PX as well as other creditors. PG&E has since filed for bankruptcy protection. As a result, the credit rating of both utilities has been reduced to noninvestment grade, and the ISO and the PX have defaulted in 2001 on payments due WCP. WCP is actively seeking the collection of its outstanding accounts receivable. However, due to previously discussed payment defaults, coupled with the lag time between receipts of revenues, payment of expenses and the increased fuel cost, WCP was forced to defer payment for a portion of its fuel cost in 2001. This deferral of payment caused WCP to be temporarily out of compliance with the terms of its GSAs. WCP's noncompliance also caused WCP to be temporarily out of compliance with the terms of its Credit Agreement. The executive committee of WCP took steps to address WCP's liquidity issues created by the California market situation as well as the resulting events of noncompliance under WCP's GSAs and Credit Agreement. These steps included (a) a negotiated deferral of payments owed under the GSAs, (b) a negotiated forbearance agreement with certain key creditors and (c) arrangement of alternative creditworthy purchasers for WCP's prospective operations. Under the forbearance agreement, which was approved by the Lenders, DMT granted forbearances with respect to the past events of noncompliance discussed above, subject to certain parameters as described therein. By December 31, 2001, WCP had paid in full all outstanding balances under the forbearance agreement, including interest costs of approximately $14.2 million. WCP is currently in compliance with its GSAs and its Credit Agreement. With all outstanding balances to DMT paid as of December 31, 2001, the forbearance agreement terminated on January 3, 2002. The state of California, through legislation appropriating funds for power purchases by the CDWR, has entered the market as a purchaser of electricity for resale to the utilities. In March 2001, WCP entered into an agreement to sell power to the CDWR through 2004, as discussed in Note 6. Under this agreement, the CDWR has always paid timely. Sales made to the ISO, which were backed by the CDWR and not related to sales under the PPA, were not paid timely. The payments were not made until after the issuance of the November 7th Federal Energy Regulatory Commission (FERC) order that required the ISO to bill the CDWR within 15 days and to file a schedule for bringing the remaining balance current within three months. By December 31, 2001, the ISO had remitted payment for February and March 2001. Since then, additional payments have been received; however, outstanding balances remain. The executive committee of WCP continues to monitor the impact of the California power and natural gas markets on the financial position and liquidity of WCP. It believes that the successful execution of the CDWR agreement as well as the desire of the conflicted parties to resolve, on a long-term basis, the pertinent issues giving rise to the current situation will provide financial stability for WCP. Litigation Class Action Lawsuits--There have been multiple class action lawsuits filed which name WCP as a defendant. The six class action lawsuits stem from the events occurring in the California power market during the summer of 2000. The complaints allege violations of California's Business and Professions Code, Unfair Trade Practices Act and various other statutes. Specifically, the named plaintiffs allege that the defendants, including the owners of in-state generation and various power marketers, conspired to manipulate the California wholesale power market to the detriment of California consumers. Included among the acts forming the basis of the plaintiffs' claims are alleged improper sharing of generation outage data, improper withholding of generation capacity and manipulation of power market bid practices. The plaintiffs seek unspecified treble damages.

The six lawsuits are at preliminary stages. Defendants in the six lawsuits have yet to file answers. The plaintiffs filed motions to remand five of the cases to state court. In respect to the sixth case, the parties agreed that, based on a judge's decision to remand the other five lawsuits, the case should go back to state court. All six lawsuits will be consolidated before a single California state court judge. After the actions were remanded, the parties agreed that the processing of these multiple actions should be coordinated. On December 12, 2001, the California Judicial Council resolved a dispute among the parties as to the county in which the actions should be coordinated, and it assigned the Coordination Proceedings (No. 4204 and No. 4205) to the Superior Court of California, County of San Diego. On December 20, 2001, the presiding judge of the San Diego Superior Court designated Judge Sammartino as the Coordination Trial Judge for the Coordination Proceedings. On January 17, 2002, Judge Sammartino set a preliminary trial conference for March 4, 2002, to, among other things, set schedules for (a) determining legal issues that might expedite disposition of the Coordination Proceedings, (b) establishing a discovery schedule and (c) resolving matters pertinent to the class action issue. The defendants in the six lawsuits have formed various joint defense groups in an effort to coordinate the defense of the claims and to share certain costs of defense. WCP believes the allegations are without merit and will vigorously defend these claims. In the opinion of management, the amount of ultimate liability with respect to these actions will not have a material adverse effect on the consolidated financial position or results of operations of WCP. FERC Orders--In response to the filing of a number of complaints challenging the level of wholesale prices, the FERC initiated a staff investigation and issued an order on December 15, 2000, implementing a series of wholesale market reforms and made subject to refund all spot market sales through the ISO and the PX markets beginning October 2, 2000. FERC also included an interim price review procedure for prices above a $150 per MW hour "breakpoint" on sales to the ISO and through the PX. The order does not prohibit sales above the breakpoint but the seller was subject to weekly reporting and monitoring requirements. In an order issued March 9, 2001, the FERC determined that only sales during so-called "Stage 3" emergency hours would be subject to refund beginning January 1, 2001. However, sales between October 2, 2000, and December 31, 2000, remained subject to refund under the FERC's December 15 order. Various parties sought rehearing of this market mitigation measure and, as explained below, the FERC ruled on the matter in an order issued on July 25, 2001. On April 26, 2001, the FERC revised its market mitigation plan, effective May 29, 2001, to cover all emergency hours. The mitigated price was to be in effect only during reserve deficiency hours. Suppliers charging prices above the mitigated price during those hours could file to justify those prices. On June 19, 2001, the FERC again revised its market mitigation plan, effective June 20, 2001. Pursuant to this plan, the FERC is mitigating prices charged in all hours throughout the Western Systems Coordinating Council based on the mitigated price in the ISO markets. During reserve deficiency hours, the mitigated price is set pursuant to an average index for gas times the heat rate of the last unit dispatched by the ISO during a "Stage 1" emergency, plus a 10 percent adder for credit risk. Nitrogen oxide charges, start-up costs and additional fuel costs will be collected through an ISO uplift charge. During nonreserve deficiency hours, the market clearing price is capped at 85 percent of the mitigated price. WCP has filed for rehearing and clarification of the order. The FERC also ordered all parties to participate in a 15-day settlement conference to determine refunds, which proved unsuccessful. Pursuant to that order, the settlement judge has issued a refund recommendation to the FERC, stating that refunds from all market participants since October 2000 probably total between several hundred million dollars and a billion dollars. The April 26, 2001, and June 19, 2001, orders apply only to sales made on a daily basis; that is, within 24 hours of delivery. After March 2001, the vast majority of power sold by WCP is committed to a long-term contract exempt from these orders. On July 25, 2001, as modified on December 31, 2001, the FERC initiated refund hearing procedures related to California wholesale spot market sales that occurred between October 2, 2000, and June 20, 2001. The July 25th order supercedes prior refund orders issued by the FERC that cover this period. In the July 25th order, the FERC developed a methodology to redetermine allegedly competitive market outcomes during each hour of this period. An administrative law judge has been appointed to determine (a) the mitigated price for

power during each hour of the refund period, (b) the amount of refunds owed by each supplier according to the FERC's methodology and (c) the amount currently owed to each supplier (with separate quantities due from each entity) by the ISO, the investor-owned utilities and the state of California. Any refunds owed would then be offset against amounts not paid. Management does not expect the administrative law judge to issue his findings before August 2002. WCP is actively participating in these proceedings and is appealing these and related orders. On December 19, 2001, the FERC issued an order that in part focused on the FERC-established price mitigation plan, which includes a formula prescribed by the FERC to determine maximum rates for wholesale power transactions in spot markets in the Western Systems Coordinating Council between June 21, 2001, and September 30, 2002. In this order, the FERC made some changes in this mitigation plan. Certain of these changes were put in place retroactively and might have the effect of reducing the applicable maximum rate in past periods. WCP has sought rehearing or clarification of this decision, pointing out that various other aspects of the December 19 order, coupled with other recent FERC orders, indicate that the FERC did not intend to modify past prices under this mitigation plan. Because of the complexity and state of this matter, the effect on WCP and whether it will lead to additional litigation cannot be predicted with certainty. In addition to the FERC investigation discussed above, several state and other federal regulatory investigations and complaints have commenced in connection with the wholesale electricity prices in California and other neighboring western states to determine the causes of the high prices and potentially to recommend remedial action. In California, the California Public Utilities Commission, the California Electricity Oversight Board, the California Bureau of State Audits, the California Office of the Attorney General and several California state legislative committees all have separate ongoing investigations into the high prices and their causes. With the exception of a report by the California Bureau of State Audits, none of these investigations has been completed and no findings have been made in connection with any of them. The California state audit report concluded that the primary causes of the market disruptions in California were fundamental flaws in the structure of the power market. Additionally, on February 25, 2002, the California Public Utilities Commission and the California Electricity Oversight Board filed complaints with the FERC asking that it void or reform power supply contracts between CDWR and, among others, WCP. The complaints allege that prices under the contracts exceed just and reasonable prices permitted under the Federal Power Act. While WCP believes the terms of its contracts are just and reasonable and do not reflect alleged market manipulation, it cannot predict how the FERC will respond to these complaints. Reserves As of December 31, 2001, WCP has reserved approximately $303.5 million related to disputed ISO revenues and penalties, disputed PX revenues, potential FERC refund amounts, accounts receivable collectibility and other miscellaneous amounts. These reserves are presented as offsets to receivables and revenue in the accompanying consolidated financial statements and represent management's best estimate of the probable exposure to losses arising from the ultimate resolution of the matters discussed above. Although such reserves may change over time as the market uncertainties are resolved, management believes such changes will not ultimately be material to WCP's consolidated financial position or results of operations. During December 2000, WCP entered into an interim agreement with the ISO. As of December 31, 2000, WCP had accrued an incremental $35 million in revenues that management believed to be associated with sales under this agreement. There is an ongoing reconciliation process between the ISO and WCP regarding this matter and, accordingly, the $35 million was reserved as contingent. Due to subsequent information provided by the ISO in 2001, WCP has revised this estimate during 2001 and included it in the above reserve. For the year ended December 31, 1999, WCP had accrued certain reserves pertaining to contingent revenues totaling approximately $10.8 million, increasing reserves from prior periods to approximately $37.8 million at December 31, 1999. These reserves were provided for various disputes with customers that were subject to

contract interpretations, compliance with processes and filed market disputes. Cash received totaling $11.4 million associated with reserves was loaned in 1999 to the Sponsors until resolution of the disputed items. These reserves were settled during 2000, and all loans to affiliates were repaid. Adjustments related to the settlement were applied against the contingent reserves with an insignificant impact on the consolidated statement of operations in 2000. 9. SUBSEQUENT EVENT: On March 11, 2002, the California attorney general filed, on behalf of the people of the state of California, complaints in San Francisco Superior Court against several energy generators, including those owned by WCP. The complaints allege that since June 1998, these generators sold power in the open market that should have been held in emergency reserve for the state. In the aggregate, the complaints seek more than $150 million in penalties, restitution and return profits from the several generators. WCP believes the allegations are without merit and will vigorously defend these claims. In the opinion of management, the amount of ultimate liability with respect to this action will not have a material adverse effect on the consolidated financial position or results of operations of WCP. 10. ACQUISITION OF CABRILLO I AND CABRILLO II: In May 1999, the Sponsors acquired the assets and liabilities of Cabrillo I and Cabrillo II from a third party. The acquisition was accounted for using the purchase method of accounting. Accordingly, the purchase cost, net of working capital, was allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. Consideration for the acquisition included cash paid of $352.5 million and the assumption of approximately $95.9 million in liabilities. The following unaudited pro forma information presents a summary of consolidated results of operations of WCP for the year ended December 31, 1999, as if the acquisition of the New LLCs by the Sponsors and subsequent transfer to WCP had occurred on January 1, 1999: Revenues $ 300,418,772 Net income 23,593,479 Consolidating Financial Statements not included.
